Pre-Evaluation
Please complete the evaluation below prior to reading any of the course material.
Introduction
There is no doubt that modern medicine has made many technological advancements over the last few decades, forging the way for highly intricate diagnostic and treatment methods and improving the quality and longevity of many lives.
In order to truly keep up with changing times, healthcare professionals must consider much more than the technical aspects of healthcare delivery. They must take a closer look and a more conscientious approach to the way in which care is delivered, particularly across a wide variety of demographics and characteristics. Ensuring care is delivered with empathy, respect, and equity, as well as noting and honoring a patient’s differences, is how care transforms from good to truly great.
Practicing diversity, equity, and inclusion (DEI), as well as cultural competence in nursing professions must become a standard.
Health Disparities
When covering cultural competence in nursing, it is vital that a provider knows that each patient is a unique individual. However, there are some characteristics such as race, gender, age, sexual orientation, or disability that can create gaps in the availability, distribution, and quality of healthcare delivered.
These gaps can create lasting negative impacts on patients mentally, physically, spiritually, and emotionally and even lead to poorer outcomes than patients not within a special population. Modern healthcare professionals have a responsibility to learn to identify risks, provide sensitive and inclusive care, and advocate for equity in much the same way that they have a responsibility to learn how the human body, medications, or hospital equipment works.
Epidemiology
In order to understand the importance of cultural competence in nursing as well as the best practices for DEI in healthcare, let’s turn to data.
Healthy People 2020 provides a myriad of data that includes countless implications for changes that need to occur in healthcare settings for equitable care of all populations.
The data includes statistics such as:
- 12.6% of Black/African American children have a diagnosis of asthma, compared to 7.7% of white children (16).
- The rate of depression in women ages 65+ is 5% higher than that of men of the same age, across all races (16).
- Teenagers and young adults who are part of the LGBTQ community are 4.5 times more likely to attempt suicide than straight, cis-gender peers (16).
- 16.1% of Hispanics report not having health insurance, compared to 5.9% of white populations (16) .
- The national average of infant deaths per 1,000 live births is 5.8. The rate for Black/African American infants is nearly double at 11 deaths per 1,000 births (16).
- 12.5% of veterans are homeless, compared to 6.5% of the general U.S. population (16).
Additional disparities are seemingly endless and point unquestionably to the fact that cultural competence and DEI awareness are no longer things that healthcare professionals can be uninformed about. The purpose of this course is to outline and explore the most common or serious healthcare disparities, address ways in which healthcare delivery needs to be adjusted, and start the conversations needed to create a new generation of healthcare professionals that will close these gaps.
The importance of understanding DEI best practices in the health setting, as well as possessing cultural competence in nursing, is vital in making positive changes for all populations.
Implicit Bias
Before even diving into the characteristics and unique circumstances of various client demographics, it is important to understand and acknowledge implicit bias. Learning information about different cultures is not enough and implicit biases held by clinicians may impede their ability to apply that knowledge in culturally competent ways and lead to care that violates the ethics of nursing.
Implicit bias is a subconscious opinion or view that can impact attitudes and behaviors. Everyone has implicit bias; it is created through a combination of the attitudes a person was raised with and around, their lived experiences, and their effort to understand the experiences of those around them; all of which influence the lens through which we view the world. This differs from explicit bias which involves conscious behaviors such as slurs, harassment, or inappropriate comments. Having implicit bias is not inherently bad, but it is important to be aware of those biases and that they may be influencing the way a healthcare professional cares for their clients (29).
An easy-to-understand example is caring for a client who comes in wearing a hat with the logo of a baseball team you like. This common ground may make you feel more connected to this client, a conversation may be easygoing and familiar, and you may feel more inclined to make sure they are having a good experience. This does not mean you dislike your clients who do not share this commonality with you, but simply that the connection with this client shapes your thoughts and behaviors in a positive manner.
More often, though, we hear about implicit bias in a negative connotation as it has the capacity to impact the way clinicians feel about their clients which spills over into the way they listen to, assess, believe, and provide care for them. Implicit bias is subtle and insidious and may go unnoticed by both the clinician and the client, but the effects are cumulative and lead to gaps in health outcomes over time. Failing to address biases may actually impact the ethics of nursing care; autonomy, justice, beneficence, nonmaleficence, and veracity (36).
Autonomy
Autonomy is the principle that clients should be respected as individuals and allowed to make their own choices about their health, bodies, and treatment plans, free from outside influence or bias. Clients will often look to healthcare professionals for guidance on what to do for their health or how to proceed with treatment. Options should be offered with information about the risks and benefits of potential treatment plans in an unbiased, nonjudgmental way so that clients can make the best and most informed decision for themselves.
Unaddressed biases could lead nurses to give nonverbal or verbal cues to what they think or expect a client to do. It could lead to subtle changes in the way care options are presented to clients or may lead to clinicians omitting certain choices altogether, ultimately reducing the autonomy clients have over their own health.
Justice
Justice is the principle that all clients deserve fair and equitable care regardless of individual circumstances or differences. The care needed by clients from certain socioeconomic backgrounds, education levels, abilities, languages, cultures, or other unique circumstances will differ from other clients and those needs should be considered and accommodated when planning care. Biases may lead healthcare professionals to feel that disadvantaged clients should not receive individualized care because it is a “handout” or they may feel pity or judgment for those clients, as a result providing unjust and inequitable care.
A common example is incarcerated clients who are just as entitled to quality healthcare as their non-incarcerated peers but are much more likely to experience biased, uncompassionate, or judgmental care.
Beneficence
Beneficence is the moral obligation to do good. Nurses acting out of beneficence will strive to prevent harm, protect clients’ rights, and work towards the best possible outcomes to improve the healthcare experience for clients. An example of a way in which implicit bias can contradict beneficence is for transgender or nonbinary clients who have a different name or pronouns than what is legally listed in their chart. Nurses with bias against these clients may not put effort into utilizing the proper pronouns of name, causing distress and emotional harm to clients, and negatively impacting their experience during an already stressful time of illness or injury.
Nonmaleficence
Nonmaleficence is often associated with the Hippocratic oath and is the principle that healthcare professionals will do no harm to their clients. This principle is often understood to be of more importance than all the rest and all other actions or principles should be conducted in such a way that they do no harm. Differences in behaviors and attitudes towards clients, including stereotyping and microaggressions can negatively impact the client experience and the principle of nonmaleficence. Often, these types of issues will lead clients to delay or stop seeking care or will cause diagnoses, possible treatments, or preventative health measures to be missed. Even if the health outcome is good, harm is still done if clients feel uncomfortable, unsafe, or disrespected during care.
An example of how implicit bias can affect nonmaleficence is assuming an elderly client is cognitively impaired and directing questions and conversation to their caregiver. This not only is condescending and disrespectful but also increases the risk that important information needed for comprehensive care will be missed by not speaking with the client directly.
Veracity
Veracity or truthfulness is the obligation to communicate openly and truthfully with clients in a respectful, objective, and timely manner. Veracity is a key component in building trust between clinician and client. When implicit bias is present, clients may sense this, and the trust relationship is broken down. Clients may have poor compliance with treatment or not ask questions if they feel mistrustful of clinicians. Lack of veracity also increases risks for clients who may not have a full understanding of their care if information is omitted due to bias.
For example, a clinician may minimize a discussion about side effects from a particular form of birth control because they feel their client is young or already has enough children and needs to take birth control regardless. Their bias does not increase the risks of the method of birth control, but the client being uninformed does increase the risk of serious complications (36).
One of the first steps in addressing implicit bias is to identify it. Biases may present in many different forms and may impact client care in obvious or more subtle ways. If this is your first time exploring your own implicit biases, it can feel overwhelming or intimidating. It can be helpful to understand some of the different types of implicit bias and examples of what they might look like in order to identify biases you may be harboring or including in your nursing care.
- Halo Effect– Halo effect bias is assuming beliefs or opinions about someone based on one aspect of their appearance that is flattering or desirable. An example in healthcare would be not asking a teenage client if they vape, drink alcohol, or use drugs because they are an attractive and put-together student. Assuming someone does or does not participate in certain behaviors based on their appearance may lead to missed opportunities to gather accurate information and may create an inaccurate assessment of the client.
- Horns Effect– Similar to the halo effect, horn effect bias is assigning beliefs or opinions about someone based on one aspect of their appearance that is deemed undesirable. In healthcare, this could be viewing overweight clients as lazy, irresponsible, or less worthy of treatment. It could also be seeing clients with a lot of tattoos as being involved in criminal activity.
- Confirmation Bias– Confirmation bias is seeking or paying more attention to information that confirms an opinion or belief rather than seeking information that disproves it. This is equivalent to “seeing what you want to see.” In healthcare, this could look like accepting a previously given diagnosis even when additional data contradicts it, or a client doesn’t quite meet criteria.
- Affinity Bias– Affinity bias is the unconscious preference for people who look or behave similarly to oneself. There is a natural tendency to feel more comfortable around people of similar backgrounds, appearances, or ways of speaking and to feel less comfortable around those who are different in these areas. This bias can lead nurses to provide care that is more compassionate or with more attention to detail for clients who are like themselves. However, they also risk providing care that is of lower quality care or less empathetic to clients who are very different from themselves.
- Attribution- Attribution bias is the tendency to explain a person’s behavior as being part of their character rather than evaluating any situational factors. This could be assuming a client who is late to an appointment is lazy or does not care about their health, when in reality they may have some very stressful external factors affecting them. Attribution bias may also be assuming clients who are noncompliant with medication are passive about their health, when in reality they may not be taking the medication because of an undesirable side effect they are afraid to mention.
- Gender Bias- Gender bias is assuming a person’s abilities, intelligence, role, or symptom severity based purely on their gender. Nurses may have gender bias against clients by assuming a female client is “chatty” or “dramatic” if she is describing multiple symptoms or issues during a visit. Nurses can hold gender bias against other healthcare professionals, assuming a woman in scrubs is a nurse and a man in scrubs is a doctor, when in reality either role may be occupied by either gender.
- Contrast Bias– Contrast bias is the effect of comparing 2 separate things against each other rather than judging them as individual circumstances. This is commonly seen through the hiring process when 2 candidates may be compared to each other and one is deemed less qualified in comparison, even though they both may be well-qualified candidates. In healthcare, this can occur when comparing clients’ responses to procedures or pain. One client in labor may be stoic and quiet while another is vocal and higher energy. Both are normal responses to pain, but the more vocal client may be seen as difficult or dramatic when compared to the quiet client.
- Anchoring Bias– Anchoring bias is being “anchored” or only focusing on one initial piece of information about a situation, which then influences a person’s decision-making ability for the rest of the situation. An example in healthcare is a client with a history of congestive heart failure (CHF) presenting to the emergency department with a complaint of shortness of breath (SOB). Since SOB is a common symptom of progressing CHF, clinicians may be initially inclined to think this is the source of the symptom. This may lead to a delay in testing or diagnosis for other potential causes of SOB, such as a pulmonary embolism. By being anchored to the initial thoughts about this client’s case, a provider risks a missed diagnosis or poor outcome.
- Conformity Bias– Conformity bias is acting similar to those around you, despite your own views or other information about a topic. In healthcare, an example of conformity bias is a nurse working in an office where many staff members have a negative or judgmental view of clients with Medicaid insurance. The nurse may not have any experience with insurance or have noticed a difference in clients based on their insurance type, however the exposure to frequent negative comments about Medicaid eventually rubs off on the nurse who now shares a negative view of these clients.
- Name Bias- Name bias is an assumption about a person’s gender, race, or ability to fluently speak English prior to even meeting them. In healthcare, name bias can be related to clients whenever their name is viewed in the chart or can also be related to the hiring of healthcare professionals when recruiters are reviewing job applications. Assumptions from a person’s name are often baseless and others may change their opinion once they meet a person, but this bias could lead to missed opportunities for those without the “preferred” sounding name; usually Western or European, white, or even male. (37,38)
Implicit biases in healthcare may not just be about nurses’ behavior towards clients but can also exist within healthcare itself. Nurses may have certain biases against other nurses who are a different age, experience level, gender, race/ethnicity, or sexual orientation than themselves and may assume those nurses are less capable, intelligent, efficient, or have a lower work ethic. This may lead to resentment and tension among a department which hurts the unit’s teamwork and cohesiveness. A department with staff tension and a lack of teamwork will indirectly hurt client care as well, as staff are more likely to be stressed, burned out, or distracted.
On a systemic level, implicit bias from those in positions of power has led to; 1) largely underrepresented minority races as healthcare providers (in 2018 56.2% of physicians were white, while only 5% were Black and 5.8% Hispanic)(30), 2) lack of support, acceptance, and resources for LGTBQ individuals in the home, workplace, school, and community, 3) varied assessment of disability and inconsistent reporting throughout the population (reports range from 12% to 30%)(31), 4) difficulty obtaining health insurance or utilizing health resources for already at-risk groups.
Self Quiz
Ask yourself...
- Consider the facility you work at and the different types of clients you encounter there. As you are meeting a new client, are there any characteristics that you use to make assumptions about them? Age, race, gender, education level, sexual orientation, or gender identity?
- Choose one of the types of implicit bias from above and think of a time when you held this type of bias (be honest, everyone has implicit biases).
- Has there ever been a time when you experienced the receiving end of implicit bias? Which type do you think it was?
Race and Ethnicity
One of the most significant disparities in healthcare, and the one garnering the most attention and campaigns for change in recent years, is race and ethnicity. However, when covering the best practices for cultural competence in nursing, it is essential that we go over this topic. Studies in recent years have revealed that minority groups, particularly Black Americans, are sicker and die younger than white Americans. Examples include:
Current data shows that Black men are more likely to be diagnosed with prostate cancer and 2.5 times more likely to die from it than their white peers. A 2019 study through the University of Michigan Rogel Cancer Center explored prostate cancer outcomes when factors such as access to care and standardized treatment plans were controlled. They found that outcomes were comparable and Black men experienced similar mortality to the white men in the study, implying that they did not “intrinsically and biologically harbor a more aggressive disease simply by being Black” (11).
A 2020 study found that Black individuals over age 56 experience a decline in memory, executive function, and global cognition at a rate much faster than their white peers, often as much as 4 years ahead in terms of cognitive decline. Data in this study attribute the difference to the cumulative effects of chronically high blood pressure, more likely to be experienced by Black Americans (20).
Black women experience twice the infant mortality rate and nearly four times the maternal mortality rate of non-Hispanic white women during childbirth. One in five Black and Hispanic women report poor treatment during pregnancy and childbirth by healthcare staff. Studies indicate that in addition to biases within the healthcare system, some of these poor outcomes may also be attributed to cumulative effects of lifelong inferior healthcare (1).
Lack of health insurance keeps many minority patients from seeking care at all. 25% of Hispanic people are uninsured and 14% of Black people, compared to just 8.5% of white people. This leads to a lack of preventative care and screenings, a lack of management of chronic conditions, delayed or no treatment for acute conditions, and later diagnosis and poorer outcomes of life-threatening conditions (4).
Emerging data indicates that hospitalizations and deaths from COVID-19 are disproportionately affecting Black and Hispanic Americans, with Black people being 153% more likely to be hospitalized and 105% to die from the disease than white people. Hispanic people are 51% more likely to be hospitalized and 15% more likely to die from COVID-19 than white people (21).
The potential reasons are many, from genetics to environmental factors such as socioeconomic status, but data repeatedly shows that these factors are not enough to account for the disproportionate health outcomes when you correct for age, socioeconomic status, and other demographics; it eventually comes down to inequity in the structure of the healthcare systems in which we all live.
For example:
- Medical training and textbooks are mostly commonly centered around white patients, even though many rashes and conditions may look very different in patients with darker skin or different hair textures (13).
- There is also a lack of diversity in physicians; in 2018, 56.2% were white, while only 5% were Black and 5.8% Hispanic. More often than not, patients will see a physician who is a different race than they are, which can mean their particular experiences as a minority person, and how that relates to their health, are not well understood by their physician (2).
- While the Affordable Care Act increased the number of people who have access to health insurance, minority patients are still disproportionately uninsured, which leads to delayed or no care when necessary (4).
- Minority patients are also often those living in poverty, which goes hand in hand with crowded living conditions and food deserts due to outdated zoning laws created during times of segregation. This means less access to nutritious foods, fresh air, or clean water which has overall negative effects on health (21).
- Much of the issues with modern healthcare come from a history of racism as the healthcare system was being built. There is a long history of mistreatment, lack of consent, and lack of representation of Black clients which has shaped some modern attitudes about care delivery as well as being passed down as generational trauma that affects the way Black clients seek out and participate in care. It is important as clinicians to understand where some of this mistrust or skepticism comes from and not misinterpret hesitancy as passivity.
Examples of historic racism include:
- One of the most infamous examples is the Tuskegee Syphilis Study which took place in 1932 and included 600 Black men, about two-thirds of whom had syphilis. During the study, the men were told that they were being treated for syphilis and they were periodically monitored for symptom progression and blood collection. In exchange, they were given free medical exams and meals. Informed consent was not collected, and participants were given no information about the study other than that they were being “treated for bad blood”, even though no treatment was actually administered. By 1943, syphilis was routinely and effectively treated with penicillin, however the men involved in the study were not offered treatment and their progressively worsening symptoms continued to be monitored and studied until 1972 when it was deemed unethical. Once the study was stopped, participants were given reparations in the form of free medical benefits for the participants and their families. The last participant of the study lived until 2004 (33).
- The “father of modern gynecology,” Dr. J. Marion Sims, is another example steeped in a complicated and racially unethical past. Though he did groundbreaking work on curing many gynecological complications of childbirth, most notably vesicovaginal fistulas, he did so by practicing on unconsenting, unanesthetized, Black enslaved women. The majority of his work was done between 1845 and 1849 when slavery was legal and these women were likely unable to refuse treatment, sometimes undergoing 20-30 surgeries while positioned on all fours and not given anything for pain. Historically his work has been criticized because he achieved so much recognition and fame through an uneven power dynamic with women who have largely remained unknown and unrecognized for their contributions to medical advancement (39).
- Another example is the story of Henrietta Lacks, a young Black mother who died of cervical cancer in 1951. During the course of her treatment, a sample of cells was collected from her cervix by Dr. Gey, a prominent cancer researcher at the time. Up until this point, cells being utilized in Dr. Gey’s lab died after just a few weeks, and new cells needed to be collected from other patients. Henrietta Lacks’ cells were unique and groundbreaking in that they were thriving and multiplying in the lab, growing new cells (nearly double) every 24 hours. These highly prolific cells were nicknamed HeLa Cells and have been used for decades in the development of many medical breakthroughs, including studies involving viruses, toxins, hormones, and other treatments on cancer cells and even playing a prominent role in vaccine development. All of this may sound wonderful, but it is important to understand that Henrietta Lacks never gave permission for these cells to be collected or studied and her family did not even know they existed or were the foundation for so much medical research until 20 years after her death. There have since been lawsuits to give family members control over what the cells are used for, as well as requiring recognition of Henrietta in published studies and financial payments from companies who profited off of the use of her cells (34).
- Breastfeeding trauma, wherein Black enslaved women were used as wetnurses, forced to separate from their own babies so they could feed the infants of their owners. This is passed down as generational trauma and lower breastfeeding initiation and continuation rates among Black clients (35).
When considering all of the above scenarios, the common theme is a lack of informed consent for Black patients and the lack of recognition for their invaluable role in society’s advancement to modern medicine. It only makes sense that these stories, and the many others that exist, have left many Black patients mistrustful of modern medicine, medical professionals, or treatments offered to them, particularly if the provider caring for them doesn’t look like them or seems dismissive or unknowledgeable about their unique concerns. Awareness that these types of events occurred and left a lasting impact on many generations of Black families is incredibly important in order for medical professionals to provide empathetic and racially sensitive care.
Potential solutions to these problems are in the works across many fronts, but the breaking down and resetting of old institutions will likely require change on a broader, political level.
Medical school admission committees could adopt a more inclusive approach during the admission process. For example, they pay more attention to the background and perspectives of their applicants and the circumstances/scenarios in which they came from as opposed to their involvement in extracurriculars (or lack of) and former education. Incentivizing minority students to choose careers in healthcare as well as investing in their retention and success should become a priority in the admissions process (13). This is one of the main drivers and only possible paths to having minority representation in healthcare systems nationwide.
Properly training and integrating professionals like midwives and doulas into routine antenatal care and investing in practices like group visits and home births will give power back to minority women while still giving them safe choices during pregnancy (1).
Universal health insurance, basic housing regulations, access to grocery stores, and many other socio-political changes could also work towards closing the gaps in accessibility to quality healthcare and may vary by geographic location.
Self Quiz
Ask yourself...
- Did you ever receive a service or do business with a company that you felt treated you unfairly? Did you feel like that experience tainted your view or made you hesitate the next time you needed a similar service?
- Imagine you received a phone call from your healthcare provider’s office letting you know that the last time you were there, they collected blood work that was used for a medical experiment. Do you think you would be surprised by this? Confused? Maybe even angry?
- Now imagine you learned the experiment your blood work was used for made millions of dollars for your clinic. How would this change the way you felt? Would you feel entitled to some of that profit?
LGBTQ
Another highly at-risk group for healthcare inequity are members of the Lesbian, Gay, Bisexual, Transexual, and Queer (LGBTQ) community. When practicing cultural competence in nursing, the provider must become aware of how vulnerable this population is, especially in healthcare settings. Risks and examples of disparities within the LGBTQ community include:
- Youth are 2-3 times more likely to attempt suicide.
- More likely to be homeless.
- Women are less likely to get preventative screenings for cancer.
- Women are more likely to be overweight or obese.
- Men are more likely to contract HIV, particularly in communities of color.
- Highest rates of alcohol, tobacco, and drug usage
- Increased risk of victimization and violence
- Transgender individuals are at an increased risk for mental health disorders, substance abuse, and suicide, and are more likely to be uninsured than any other LGB individuals (17)
Current data suggests that most of the health disparities faced by this group of people are due to social stigma, discrimination, lack of access or referral to community programs, and implicit bias from providers leading to missed screenings or care opportunities.
Support systems and social acceptance are strongly linked to the mental health and safety of these individuals. Lack of support and acceptance in the home, workplace, or school leads to negative outcomes. Also, a lack of social programs to connect LBGTQ individuals to each other and build a community of safety and acceptance creates further gaps.
There is currently still discrimination in access to health insurance and employment for this population which can affect accessibility of quality health care as well as affordable coverage.
Following this, a compilation of recent data showcases that there are significant issues with the quality and delivery of care provided to those in the LGBTQ community.
This data includes:
- In a 2018 survey of LGBTQ youth, 80% reported their provider assumed they were straight and did not ask (18).
- In 2014, over half of gay men (56%) who had been to a doctor said they had never been recommended for HIV screening (14).
- A 2017 survey of primary care providers revealed that only 51% felt they were properly trained in LGBTQ care (25).
Although it is unclear as to whether this data stems from a lack of education or social awareness from the provider, it is evident that change needs to be made. At the root of many of the biases regarding LGBTQ clients is a lack of understanding when caring for people in this community. It is important for healthcare professionals to familiarize themselves with the definitions and differences in sexuality, gender identity, and the many terms within those categories to have a better understanding of how these factors affect the health and safety of clients. A glossary for reference and better understanding has been included at the end of this course.
In order to improve these conditions and close the gap for LGBTQ individuals, much can be done on the community level and in medical training:
- Community programs should be available to create safe spaces for connection and acceptance.
- Laws and school policies can focus on how to prevent and react to bullying and violence against LGBTQ individuals.
- Cultural competence training in medical professions needs to include LGBTQ issues.
- Data collection regarding this population needs to increase and be recognized as a medical necessity, as it is largely ignored currently.
It is essential for providers to stay up to date on changes and health trends among the LGBTQ population, as healthcare delivery methods may require adjustments over time; this is critical when learning about cultural competence in nursing.
Case Study:
Justin is a 44-year-old male who presents to the family practice office for an annual physical. He indicates some mild depression since a recent breakup with his long-term girlfriend but otherwise denies complaints today.
His exam is normal, and he had routine lab work at his physical last year, so none is ordered today. His PCP refers him for psychotherapy and indicates that if his depressive symptoms have not improved within 6-8 weeks, starting an SSRI may be beneficial.
Justin leaves the appointment with a referral and scheduled follow-up and nothing else. What the PCP failed to realize was that Justin ended his recent relationship to come out as gay and he has been dating men for about 4 months now. He was not asked to update any demographic information at check-in and was embarrassed to bring up the topic on his own.
Discussion
In this case, the PCP did not have a full picture of the client’s health history and risk factors. By assuming that Justin was still heterosexual because his last partner was a woman, the opportunity to educate about risks and screen for STIs, particularly HIV, was missed. Justin also may be a good candidate for medications like PREP and could benefit from the reduced risk of contracting HIV. A discussion about this medication and if it is a good fit for the client did not take place.
Self Quiz
Ask yourself...
- Think about a patient you have cared for who did not come in with a significant other. Did you make any assumptions about that client’s sexual orientation or gender identity?
- Would there have been different risk screenings you needed to perform if they were part of the LGBTQ community?
- Have you ever had someone repeatedly call you the wrong name or assume something incorrect about you? How did it make you feel?
Gender and Sex
Gender and sex play a significant role in health risks, conditions, and outcomes due to a combination of factors, including biological, social, and economic elements.
Among the differences in health data related to gender are:
- Women are twice as likely to experience depression than men across all adult age groups (7).
- About 12.9% of school-aged boys are diagnosed and treated for ADHD, compared to 5.6% of girls, though the actual rate of girls with the disorder is believed to be much higher (9).
- A 2010 study showed men and women over age 65 were about equally likely to have visits with a primary care provider, but women were less likely to receive preventative care such as flu vaccines (75.4%) and cholesterol screening (87.3%) compared to men (77.3% and 88.8% respectively) (5).
- In the same study, 14% of elderly women were unable to walk one block, as opposed to only 9.6% of men at the same age (5).
- Heart disease is the leading cause of death in women, yet women are shown to have lower treatment rates for heart failure and post-heart attack care, as well as lower prevalence but higher death rates from hypertension than men (6).
It is also important to differentiate the difference between gender and sex when practicing cultural competence in nursing.
Sex is the biological and genetic differentiation between male and female, whereas gender is a social construct of difference in societal norms or expectations surrounding men and women. For someone looking to better practice cultural competence in nursing and provide both equitable and inclusive care, it is essential that you know this differentiation.
Some health conditions are undeniably attributable to the anatomical and hormonal differences of biological sex; for example, uterine cancer can only be experienced by those who are biologically female. Many of the inequalities listed above disproportionately burden women due to the social and economic differences they experience in society; for example, 1 in 4 women experience intimate partner violence as compared to 1 in 9 men (22).
What are the reasons for this? A lot of it has to do with how women are perceived in society, how their symptoms may present differently than male counterparts, or how their symptoms are presented to and received by medical professionals.
For centuries, any symptoms or behaviors that women displayed (largely mental health related) that male doctors could not diagnose fell under the umbrella of hysteria. The recommended treatment for this condition was anything from herbs, isolation, sex, or abstinence and it is only in the last one hundred years or so that more accurate medical diagnoses began to be given to women. Hysteria was not deleted from the DSM until 1980 (27).
The Cameron study found that women were more verbose in their encounters with physicians and may not be able to fit all their complaints into the designated appointment time, leading to a less accurate understanding of their symptoms by their doctor (5).
The same study also indicated that women tend to have more caregiver responsibilities and feel less able to take time off for hospitalizations or treatments (5).
Symptoms of mental health disorders like ADHD may look different in girls than in boys. Girls who are having difficulty focusing may be categorized as “chatty” or a “daydreamer” by teachers, whereas boys are more likely to draw attention for being hyperactive or disruptive when both are experiencing symptoms of ADHD and could benefit from treatment (10).
To close these gaps and ensure equitable care for men and women, the way that teachers, doctors, and nurses view and respond to girls and women must be adjusted.
- Children who are struggling in school should be looked at more comprehensively and the differences in learning styles widely understood.
- Screening questionnaires and standard preventive care used when caring for clients in primary care.
- Social services should be utilized to help determine if women are pushing aside their own healthcare needs due to responsibilities at home.
- Medical professionals must be trained in the history of inequality among women, particularly regarding mental health, and proper, modern diagnostics must be used.
- The differences in communication styles of men and women should be understood when caring for patients.
Self Quiz
Ask yourself...
- In what ways do you think the history of “hysteria” in women may still be subtly present today?
- Think about the way we use the word hysterical in language. Now consider that the word is related to having a uterus and how this might influence cultural views of women.
- Consider that girls are diagnosed with ADHD about half as often as boys. In what ways do you think their symptoms differ?
Religion
Religion can impact when patients seek care, which treatments they will participate in, and how they perceive their care. Even advanced technology in healthcare can be perceived as unsatisfactory if it violates religious preferences for patients, so it is very important for healthcare professionals to be aware of certain religious preferences to provide the most competent and sensitive care possible.
Consequences of culturally incompetent care include:
- Negative health outcomes due to not participating in care that violates their religious beliefs.
- Patient relationships with healthcare professionals can suffer if they feel disrespected or misunderstood, causing patients to delay or avoid seeking care altogether.
- Dissatisfaction with care which can even lead to long-term trauma surrounding major events like birth, death, or chronic disease if a patient felt uninvolved or disrespected in their care (26).
There are many religions with different practices and ordinances, but we will cover some of the more major and common implications regarding health practices here. Typically, views on pregnancy/birth, death, diet, modesty, and treatment for illness are the most important areas for healthcare professionals to understand. Providers must continue to educate themselves on the practices and preferences of various religions; it is essential to practicing cultural competence in nursing.
Disclaimer: Please note that each religion has many variations and that not all practices may be the same. The following information has been sourced from “Cultural Religion Competency in Clinical Practice,” written by Drs. Diana Swihart, Siva Naga S. Yarrarapu, and Romaine L. Martin (26).
Buddhism
Study and meditate on life, cause and effect, and karma, working towards personal enlightenment and wisdom. They believe the state of mind at death determines their rebirth and prefer a calm and peaceful environment without sedating drugs. Have ceremonies around birth and death. Their diet is usually vegetarian (26).
Christian Science
Based on the belief that illness can only be healed through prayer. They typically choose spiritual healing for disease or illness prevention and treatment. Often refuse vaccines and delay treatment for acute illnesses. They avoid tobacco and alcohol but have no other dietary restrictions (26).
The Church of Jesus Christ of Latter-Day Saints/Mormon
Heavily family-oriented, involvement of family in major health/life events is important. Strict abstinence outside of heterosexual marriage. Fasting is required monthly, exempt during illness. Blood or blood products are accepted. Abortion is prohibited unless it is a result of rape or the mother’s life is in danger. Two elders present for the blessing of those ill or dying (26).
Hinduism
Centers on leading a life that allows you to reunite with God after death. Believes in reincarnation and so the environment around dying people must be peaceful. The presence of family and a priest during end of life is preferable. After death, the body is washed and not left alone until cremated. Euthanasia is forbidden. The right hand is used for eating (26).
Islam
Belief in God and the prophet Abraham. Prayer is required five times daily. Observe Ramadan, a month of fasting and abstinence during daylight (children and pregnant women are exempt from fasting). Autopsies should only be performed if legally necessary. Must eat clean, halal, food and excludes pork, shellfish, and alcohol. Female patients require female healthcare providers. Abortion is prohibited (26).
Jehovah’s Witness
Believe the destruction of the present world is coming and true followers of God will be resurrected. Do not celebrate birthdays or holidays. Believe death is a state of unconscious waiting. Euthanasia prohibited. Refuse blood and blood products. Abortion is prohibited. Pregnancy through artificial means (IUI, IVF) is prohibited (26).
Judaism
Belief in an all-powerful God and varying levels of interpretation/observance of laws and traditions. Cremation is discouraged or prohibited. Prayer is important for the sick and dying, after death the body is not left alone. Must eat kosher foods, which excludes pork. Amputated limbs must be saved and buried where the person will one day be buried. Abortion is allowed in certain circumstances (26).
Protestant
Christian faith formed in resistance to Roman Catholicism. Autopsy and organ donation are acceptable. Euthanasia is not acceptable. No restrictions on diet or traditional western medicine treatments (26).
Roman Catholicism
Christian faith is steeped in tradition and observance of sacraments. Clergy is present at end of life for the sacrament of Last Rites. Avoid meat on Fridays during Lent. Mass and Communion on Sundays is an obligation, and they may require a clergy member to visit during hospitalization. Abortion and birth control (other than natural family planning) are prohibited. Artificial conception is discouraged. Newborns with a grave prognosis need to be baptized (26).
To better practice cultural competence in nursing and improve the quality of care given that respects a patient’s faith and religious boundaries, one should focus on:
- Understanding basic differences and preferences with various religions and providing training for staff.
- Encouraging family to participate in health decision-making where appropriate.
- Providing interpreters where needed.
- Promoting an environment that allows for clergy, healers, or other religious figures of comfort to visit and participate in care if desired.
- Providing dietary choices that are considerate of religious dietary preferences.
- Recruiting staff that are minorities or of various religions.
- Respecting a client’s views on controversial topics such as pregnancy/birth, death, and acceptance or declining of treatments even if it conflicts with staff members’ own beliefs (26).
Self Quiz
Ask yourself...
- Imagine you work on a maternity unit and are caring for a new mother who observes the Islamic faith. What needs might she have in order to feel respected and comfortable with her care?
- Consider how religious needs being met or unmet might impact a client’s perception of their care, regardless of the health outcome.
- In what ways do you think met or unmet spiritual needs might impact care long after it has occurred, especially during times of birth or death?
Case Study
The nurse is caring for a terminally ill 78-year-old woman, Patricia. Several weeks ago, the client and her family decided that when the disease progressed, she would like to be placed on hospice and die at home without extraordinary measures or resuscitative efforts. The family is Roman Catholic and has also requested a priest be present to administer Last Rites.
Patricia was placed on hospice earlier this week and her condition has worsened to the point where death is near, and the priest has been called in. The nurse assists with clearing and tidying the space around Patricia’s bed and has brought in additional seating for family members. The priest performs the sacrament of Last Rites and then the family sits around the bed and prays together. The nurse administers pain medication on occasion, but for the most part, allows space for the family’s religious needs. After a few hours, Patricia dies, and the family continues to sit with her. They are sad, but overall, there is a sense of peace.
The nurse checks on the family a few weeks later as part of a follow-up program for grieving families. Patricia’s husband and children all agree that while they are grieving her loss, they feel a sense of spiritual peace with the time surrounding her death and they know it is what she wanted.
Discussion
This is an example of how attention to the beliefs and wishes of clients plays an important role in client and family perception of care received compared to the overall health outcomes. This client was terminally ill, so the health outcome was never going to be recovery or disease treatment. The client’s comfort level surrounding the end of life and the grieving process for the family afterward were both facilitated by making space for religious and spiritual needs in addition to medical care.

Age
As the Baby Boomer generation ages, there is a growing number of older adults in the U.S. In 2016, there 73.6 million adults over age 65, a number which is expected to grow to 77 million by 2034. As of 2016, 1 in 5 older adults reported experiencing ageism in the healthcare setting (24). As the number of older adults needing healthcare expands, the issue of ageism must be addressed. For providers looking to improve cultural competence in nursing practices, it is vital that ageism is addressed, as it flies under the radar. Ageism is defined as stereotyping or discrimination against people simply because they are old.
Ways in which ageism is present in healthcare include:
- Dismissing a treatable condition as part of aging.
- Overtreating natural parts of aging as though they are a disease.
- Stereotyping or assuming the physical and cognitive abilities of a patient purely based on age.
- Providers being less patient, responsive, and empathetic to a patient’s concerns or even talking down to patients or not explaining things because they believe them to be cognitively impaired.
- Elderly patients may internalize these attitudes and seek care less often, forgo primary or preventative screenings, and have untreated fatigue, pain, depression, or anxiety
- Signs of elder abuse may be ignored or brushed off as easy bruising from medication of being clumsy (24).
There are many reasons why ageist attitudes in healthcare may occur, including:
- Misconceptions and biases among staff members, particularly those that have worked with a frail older population and assume all elderly people are frail.
- Lack of training in geriatrics and the needs and abilities of this population.
- Standardizing screenings and treatments by age may help streamline the treatment process but can lead to stereotyping.
- Changing this process and encouraging an individual approach may be resisted by staff and viewed as less efficient.
In order to combat ageism and make sure healthcare is appropriately informed to provide respectful, equitable care:
- Healthcare professionals can adopt a person-centered approach rather than categorizing care into groups based on age.
- Facilities can adopt practices that are standardized regardless of age.
- Facilities can include anti-ageism and geriatric-focused training, including training about elder abuse.
- Healthcare providers can work with their elderly patients to combat ageist attitudes, including internalized ones about their own abilities (24).
On the opposite end of the lifespan, children are vulnerable to gaps in care due to assumptions about their cognitive capacity to participate in their care. Healthcare professionals may ignore or minimize communication from young clients, dismissing their concerns as trivial or something to be handled by adults.
This is partly because most medical decision making does require parental consent for anyone under the age of 18, with some exceptions for sensitive issues like STIs depending on your state. However, just because the final decision-making authority lies with the parents doesn’t mean that children and teens have no opinions or desire to be a part of their care (32).
Children also may exhibit behaviors that are less cooperative than adults due to pain, fear, or illness. This is developmentally appropriate and should not be labeled as “difficult” or “bratty,” but approached with empathy and an understanding of different developmental levels.
Different approaches include:
- Distractions such as toys, songs, videos, and comforts like hugs or breastfeeding should be used for babies and toddlers who are too young to understand what is happening.
- Play can be used for preschoolers to help demonstrate wearing hospital gowns/shoes/caps, giving medicine, or changing bandages. Preschoolers can be given simple explanations and use play to eliminate some of the unknown and prepare for hospital or clinic experiences.
- School age children can be given more detailed information and may enjoy picture books or stories. They should be given the opportunity to ask questions that should be answered honestly and not dismissed with responses like “You don’t need to worry.”
- Teenagers should be included in a full discussion of the risks versus benefits of treatment plans and more advanced information or even pamphlets and reading materials can be given about the disease process or treatment. This age group is striving for autonomy and should be treated respectfully, allowed to be a part of the decision-making process, and given privacy when possible and appropriate. Responsibility for their health should be shifted to them while still under the supervision of an adult. Teenagers who are taken seriously and given respect as an individual are more likely to form a trusting rapport with healthcare professionals, which is in turn necessary for their cooperation and compliance with treatment plans (32).
- It should also never be assumed that teenagers are “too young” be engaging in risky behaviors such as smoking, drugs, alcohol, or sexual activity. Making assumptions opens the door for missed screenings and preventative care (32).
Child Life specialists are a wonderful resource that should be utilized whenever available; these professionals are licensed in child development and assist with coping and education for children and adolescents in the hospital or clinic setting. They can be present for situations ranging from a simple blood draw to disclosing a terminal diagnosis (32).
Age specific treatment requirements change across the lifespan, and an important part of cultural competence is familiarity with the unique needs, strengths, and challenges of each age group. Familiarity with Erikson’s stages of development with help clinicians better understand their clients’ needs and customize care accordingly.
A brief review of Erikson’s stages of development is included below.
- Trust vs Mistrust, birth to 2 years: Infants and young toddlers in this stage are completely dependent on others to meet their needs. Their communication is very limited (crying) and, if cared for, they quickly learn that their needs will be met, and they are safe. If infants in this stage receive poor care, they may be fearful and struggle to trust their needs will be met.
- Autonomy vs Shame and Doubt, 2-3 years: At this stage, toddlers are seeking more control over choices and their bodies (and may even have tantrums when they want control). Skills, such as feeding themselves, getting dressed, communicating more effectively, helping with small tasks, and potty training provide a sense of confidence. If toddlers are not given some control over their own choices and bodies, they may doubt their abilities or feel shame.
- Initiative vs Guilt, 3-5 years: In this stage, children learn to explore, make decisions, and assert themselves in social interactions. If allowed freedom to explore the effect of their choices and interactions, children will develop a sense of initiative. If they are repressed through control or criticism, they will develop a sense of guilt.
- Industry vs Inferiority, 6-11 years: In this stage, children work to improve their abilities and seek recognition of their competence. If encouraged and praised, children will develop a sense of confidence. If ridiculed or discouraged, they will doubt their abilities.
- Identity vs Confusion, ages 12-18 years: This is the period of adolescence which is famously tumultuous. At this stage, individuals work to better understand their values, interests, and sense of self separate from the family unit. They seek independence and control over their appearance and how they spend their time and their acceptance in a peer group is important. Adolescents who receive positive reinforcement for their individuality will develop a strong sense of self. Those who do not receive positive reinforcement will lack confidence and feel insecure.
- Intimacy vs Isolation, 19-40 years: In this stage, adults work to form deeper and more intimate relationships, through both romantic partners and friendships. Success during this stage depends on how successfully a person achieved the previous stages. Those who are able to form strong relationships with others feel a sense of intimacy and contentment, whereas those with poor or unstable relationships will feel isolated and lonely.
- Generativity vs Stagnation, 40-65 years: During this stage, adults work to create and solidify a good and productive life, contributing to the world through careers, family, and community engagement. Those who are successful will feel a sense of connection and motivation, those who are unsuccessful may feel disconnected or stagnant.
- Integrity vs Despair, 65+: In this stage, older adults begin to look back on their lives and evaluate the impact or goals they have accomplished or failed to accomplish. Adults who feel proud or accomplished with all they have done will have a sense of integrity and satisfaction, whereas those with many regrets or lack of pride will feel despair or bitterness. (41)

Ask yourself...
- Have you ever cared for two elderly patients of the same age who seemed drastically different in their overall health and independence? Why do you think that is?
- Do you think seeing a client’s age on their chart (either very young or very old) influences how you feel about them before you even meet them?
- Think about Erikson’s developmental stages. Why do you think it is important to provide school age children with accurate information about their care and answer their questions rather than dismissing them?
Case Study
Sydney is a 17-year-old client who presents to the pediatric office alone with a complaint of dysuria. She has been coming to this office for years but has never spoken with her nurse practitioner alone, so she is feeling nervous, particularly given the nature of her symptoms.
She reports pelvic pain and dysuria for about 2 weeks, along with some foul smelling yellow vaginal discharge. She admits to being sexually active with 2 partners in the last year. She reports using condoms inconsistently. She does take hormonal birth control for acne, which is listed in her chart.
On exam, she has pelvic tenderness and yellow vaginal discharge. Otherwise, her exam is normal. The NP discusses that based on her history and exam; a diagnosis of chlamydia is likely. A urine sample is collected, and the NP states it will take a day or two for results to come back but that she can be started on an antibiotic now while awaiting results.
This NP has known Sydney for many years, knows her mother well, and knows that abstinence is the preferred method of sex education taught in Sydney’s home. The NP agrees that Sydney is too young to be sexually active and feels very concerned that she has contracted an STI and decides to contact Sydney’s mother to inform her of today’s visit.
Sydney’s mother is furious at this information and prohibits Sydney from attending prom the following week. She restricts access to her phone and activities outside of school. Sydney is distraught over the conflict at home and over the following weeks develops depressive symptoms with suicidal thoughts. She has sports physical for summer camp the following month but does not disclose any of her depressive symptoms to the NP as she now feels a lack of trust and that the NP just views her as a child with no autonomy.
Discussion
Consider this case and how the NP’s own implicit biases affected the care Sydney received. Now that the trust is broken between Sydney and her provider, the chances that she will seek care for future problems is small. This could result in serious negative health outcomes, particularly since she is experiencing suicidal thoughts and is at risk for self harm.
Now imagine this same case, but instead of the NP interjecting their own biases about the client, they follow Nevada law which allows minors to receive confidential treatment for STIs without parental consent. Sydney could be treated discreetly without her parent’s knowledge and the NP could utilize the opportunity to discuss safe sex and the importance of using condoms. This is much more likely to result in a positive outcome for Sydney, as she will be treated for the chief complaint, as well as be empowered to practice safer sex and hopefully avoid future STIs. She will also maintain a trusting relationship with this provider and feel comfortable making appointments for future concerns.
Self Quiz
Ask yourself...
- Do you think this case might have gone differently if Sydney had been 20 instead of 17?
- What are the risks of a teenager who does not feel she can confide in a parent or a healthcare professional when experiencing a health problem?
- The most competent form of care for Sydney should actually have started years ago by allowing her to speak with the NP privately at her wellness visits. How do you think Sydney’s case might have been different if she had an existing relationship of trust with this NP before she even became sexually active?
Veterans
Veterans are a unique population that faces many health concerns unique to the conditions of their time in service. Much of veteran health care is provided through the Veteran Affairs (VA) facilities, a nationalized form of healthcare involving government-owned hospitals and clinics and government-employed healthcare professionals. Again, the purpose of this course is to educate providers on how to practice cultural competence in nursing; however, let’s introduce the disparities found within this population by utilizing a few statistics.
- 1 in 5 veterans experience persistent pain and 1 in 3 veterans have a diagnosis related to chronic pain (8).
- Approximately 12% of veterans experience symptoms of PTSD in their lifetime, compared to 6% of the general population and 80% of those with PTSD also experience another mental health disorder such as anxiety or depression (8).
- More than 1 out of every 10 veterans experiences some type of substance use disorder (alcohol, drugs), which is higher than the rate for non-veterans (8).
- In 2019, around 9% of homeless adults were veterans (28).
- Veterans account for 20% of all suicides in the U.S., despite only about 8% of the U.S. population serving in the military (8).
- Disparities also exist within the veteran population and veterans who are a minority race or female experience these issues at an even higher rate
- For example, veteran women are twice as likely to experience homelessness than veteran men (28).
The causes of these troubling issues for veterans are multifaceted; some of them relate to the nature of work in the U.S. Military and increased exposure to trauma (particularly with those involved in combat), and some of them relate to the care of veterans, and their mental health during and after their service.
- 87% of veterans are exposed to traumatic events at some point during their service (8).
- Current data suggests fewer than half of eligible veterans utilize VA health benefits
- For some this means they are receiving care at a non-VA facility and for others it means they are not receiving care at all.
- Care at civilian facilities means healthcare professionals who may not have a full understanding of veteran issues (12).
- Less than 50% of veterans returning from deployment receive any mental health services (23).
All service members exiting the military are required to participate in the Transition Assistance Program (TAP), an information and training program designed to help veterans transition back to civilian life, either before leaving the military or retiring. The program is evaluated annually for effectiveness and currently includes components about skills and training for civilian jobs and individual counseling regarding plans after exit.
- Adding or strengthening components of TAP surrounding mental health care and utilization of VA healthcare services would be beneficial and could help reduce disparities.
- Changing the military culture surrounding mental health to strengthen and mandate training and usage of debriefing for active duty military could be beneficial as well.
- Incentivizing usage of the VA healthcare system for routine preventative and mental health care would help reach more veterans who may be in need.
- Additional training for healthcare professionals working within the VA with an emphasis on mental health disorders would ensure high-quality of care for veterans utilizing their services.
Self Quiz
Ask yourself...
- How could trauma better be handled for these patients in order to reduce their risk of all the other related issues?
- Why do you think some of the reasons could be that half of all Veterans do not utilize VA resources?
- How do you think clients with Veteran status might be cared for differently by civilian clinicians rather than those who work exclusively with Veterans?
Mental Illness and Disability
Disabilities are emerging as an under-recognized risk factor for health disparities in recent years, and this new recognition is a welcome change as more than 18% of the U.S (15) population is considered disabled. Disabilities can be congenital or acquired and include conditions that people are born with (such as Down Syndrome, limb differences, blindness, deafness), those presenting in early childhood (Autism, language delays), mental health disorders (bipolar, schizophrenia), acquired injuries (spinal cord injuries, limb amputations, change in hearing/vision), and age related issues (dementia, mobility impairment).
Public health surveys vary from state to state, but most categorize a condition as a disability based on the following: 1) blindness or deafness in any capacity at any age, 2) serious difficulties with concentrating, remembering, and decision making, 3) difficulty walking or climbing stairs, 4) difficulty with self-care activities such as dressing or bathing, 5) and difficulty completing errands, such as going to an appointment, alone over the age of 15 (19).
Health disparities affecting people with disabilities can include the way they are recognized, their access and use of care, and their engagement in unhealthy behaviors. In order to practice cultural competence in nursing, understanding the disparities that those with disabilities face is essential.
- Due to variations in the way disabilities are assessed, the reported prevalence of disabilities ranges from 12% to 30% of the population (19).
- People with disabilities are less likely to receive needed preventative care and screenings (15).
- Only 78% of women with disabilities were up to date with their pap test, while over 82% of non-disabled women were up to date with this preventative screening (19).
- People with disabilities are at an increased risk of chronic health conditions and have poorer outcomes (15).
- 27% of people with disabilities did not see a doctor when needed, due to cost, as opposed to only 12% of non-disabled peers (19).
- 21% of children with disabilities were obese, compared to 15% of children without disabilities (19).
- People with disabilities are more likely to engage in unhealthy behaviors such as cigarette smoking and lack of physical exercise than people without disabilities (15).
- During Hurricane Katrina, 38% of the people who did not evacuate were limited in their mobility or providing care to someone with a disability (19).
Many of the health differences between those with and without disabilities come down to social factors like education, employment (finances), and transportation which significantly affect access to care.
- 13% of people with disabilities did not finish high school, compared to 9% of non-disabled peers.
- Only 17% of people over the age of 16 with disabilities were employed, compared to nearly 64% of non-disabled peers.
- Only 54% of people with disabilities had at-home access to the internet, compared to 85% of people without disabilities.
- 34% of people with disabilities reported both an annual income <$15,000 and access to transportation, compared to 15% and 16% respectively for people without disabilities.
- Fewer than 50% of people with disabilities have private insurance, while 75% of people without disabilities have private health insurance.
- Even for those insured, 16% of people with disabilities have forgone care due to cost, compared to only 5.8% of insured people without disabilities (19).
If access to necessary preventive and acute health care is to be increased for those with disabilities, much must be changed in regard to the social determinants affecting this population. Policy changes on a community, state, and federal level will be needed to provide the social and economic support these people need. Potential solutions include:
- Streamline and standardize the process of identifying people with disabilities so they can be eligible for assistance as needed.
- School programs to help people with disabilities graduate and find jobs within their ability level.
- Community participation in making sure transportation, buildings, and facilities are accessible to all.
- Make internet access a basic and affordable utility, like running water and electricity.
- Address the inequities in health insurance accessibility and coverage.
- Provide social and economic support programs for parents of children with disabilities and provide transitional support as those children become adults (15).
Self Quiz
Ask yourself...
- Have you ever cared for a patient with a serious disability? Consider the ways in which even getting to the clinic or hospital where you work might be different or more challenging than for patients without a disability.
- What resources for people with disabilities are available in the community where you live?
- How do you think those resources might vary in surrounding areas?
LGBTQ Term Glossary
- Sex: A label, typically of male or female, assigned at birth, based on the internal reproductive structures, external genitals, secondary sex characteristics, or chromosomes of a person. Sometimes the label “intersex” is used when the characteristics used to define sex do not fit into the typical categories of male and female. This is static throughout life, though surgery or medications can attempt to alter physical characteristics related to sex.
- Gender: Gender is more nuanced than sex and is related to socially constructed expectations about appearance, behavior, and characteristics based on gender. Gender identity is how a person feels about themselves internally and how this matches (or doesn’t) the sex they were assigned at birth. Gender identity is not related to who a person finds physically or sexually attractive. Gender identity is on a spectrum and does not have to be purely feminine or masculine and can also be fluid and change throughout a person’s life.
- Cis-gender: When a person identifies with the sex they were assigned at birth.
- Transgender: When a person identifies with a different sex than the one they were assigned at birth. This can lead to gender dysphoria or feeling distressed and uncomfortable when conforming to expected gender appearances, roles, or behaviors.
- Nonbinary: When a person does not identify as entirely male or female. A nonbinary person can identify with some aspects of both male and female genders, identify with certain characteristics at different times, or reject both entirely.
- Sexual orientation: A person’s identity in relation to who they are attracted to romantically, physically, and/or sexually. This can be fluid and change over time, so do not assume a client has always or will always identify with the same sexual orientation throughout their life.
- Heterosexual/Straight: Being attracted to the opposite sex or gender as your own.
- Homosexual/Gay/Lesbian: Being attracted to the same sex or gender as your own.
- Bisexual: Being attracted to people of many sexes, including your own.
- Pansexual: Being attracted to people, regardless of sex or gender presentation.
Conclusion
In short, cultural competence in nursing means that although a provider may not share the same beliefs, values, or experiences as their patients, they understand that in order to meet the patient’s needs, they must tailor their care delivery. Nurses are patient advocates, and it is on them to ensure that they are providing equitable and inclusive care to all populations.
However, cultural competence in nursing is ever-changing and it is the responsibility of the provider to stay up-to-date in order to offer the best experience for all patients.
Bioterrorism in Nursing
With advancements of science and developments in microbial genetics, there is heightened concern regarding the abuse of these discoveries for acts of terrorism and war. Effective preparedness is a crucial asset to have in the management of an attack. Nurses and other healthcare practitioners play a vital role in this preparedness. It is essential that they have some knowledge of the prevention and control practices as well as knowledge of the various biological, chemical, nuclear, and radioactive agents that may be used in a potential intentional attack. Arming healthcare providers with expertise in preparedness, management, and treatment will allow for a smoother transition of action if a public health emergency ensues. It is vital for nurses to understand bioterrorism in nursing as nurses would play a major role in treatment of individuals affected by such an event.
Introduction
The threat of biological warfare may seem like a farfetched idea, something only one may see in a movie. However, with the recent events of our world, it seems more and more likely. With advancements of science and developments in microbial genetics, there is heightened concern regarding the abuse of these discoveries for acts of terrorism and war. Although regulations and procedures are securing the exposure or release of such pathogens in research laboratories exist, there is still risk involved.
Effective preparedness for bioterrorism in nursing staff is a crucial asset to have in the management of an attack. Nurses and other healthcare practitioners play a vital role in this preparedness. It is essential that they have some knowledge of the prevention and control practices as well as knowledge of the various biological, chemical, nuclear, and radioactive agents that may be used in a potential intentional attack. Arming healthcare providers with expertise in preparedness, management, and treatment will allow for a smoother transition of action if a public health emergency ensues.
“Bioterrorism is the intentional release or threat of release of biologic agents (i.e., viruses, bacteria, fungi, or their toxins) to cause disease or death among the human population or food crops and livestock to terrorize a civilian population or manipulate a government (1).”
Preparedness for bioterrorism in nursing staff will improve the ability to detect and control other infectious diseases.
“Weapons of mass destruction are atomic explosive weapons, radioactive material weapons, lethal chemical, and biological weapons, that are intended to harm a large number of people (2).”
Characteristics of Bioterrorist attack (1):
- The infectious agent used is likely to be uncommon and not prevalent to the region.
- May be genetically modified to make it resistant to vaccines and medications.
- It was produced in a way that enhances its transmission.
- Has the characteristics of a mass casualty event.
- Have a short and predictable incubation period.
- The target population should have little or no immunity against the organism.
- Little or no treatment should be available with the native population.
- It can be either covert or announced and can be caused by any pathogenic microorganism.
Weapons of mass destruction have the potential to (2):
- Produce a single moment of enormous destructive effect capable of killing millions of civilians, jeopardizing the natural environment, and altering the lives of future generations through their effects.
- Cause death or serious injury of people through toxic or poisonous chemicals
- Disseminate disease-causing organisms or toxins to harm or kill humans, animals or plants.
- Deliver nuclear explosive devices, chemical, biological, or toxin agents to use them for hostile purposes or in armed conflict.
Classification of Biological Weapons
Several bioterrorist agents that are classified as the most dangerous include anthrax, botulism, plague, smallpox, tularemia, and viral hemorrhagic fevers. Bioterrorist attacks can also come in the form of food or waterborne agents (1). Biological weapons are classified into different categories by the Center for Disease Control (CDC). Agents of bioterrorism are classified into three groups Category A, Category B, and Category C. They are based on the agents’ priority to cause a risk to national security and how easily they can be disseminated.
Category A: High Priority Agents
- Easily disseminated
- Cause high mortality
- Cause public panic and social disruption
- Require special action for public health preparedness
Category B: Second Highest Priority Agents
- Moderately easily to disseminate
- Cause moderate morbidity
- Require enhanced disease surveillance and public health diagnostic capacity (3, 4, 5)
Category C: Third Highest Priority Agents
- Could be engineered for mass dissemination in the future
- Have potential for high morbidity mortality and major health impact
Agents of Bioterrorism (3, 4, 5)
Category A Agents | Category B Agents | Category C Agents |
Anthrax | Alpha Viruses | Hanta viruses |
Botulism | Eastern and Western Equine Encephalomyelitis virus | Multidrug-resistant tuberculosis |
Tularemia | Brucellosis | Nipah virus |

Biological Agents
Anthrax
Anthrax is a severe infection caused by the bacterium Bacillus anthracis. In 2001, 22 cases of the disease were reported in the United States after anthrax spores were sent through the mail. Anthrax can be contracted in three different ways. Each type of infection has differing signs and symptoms. Person-to-person transmission of this disease is rare. It can also be naturally occurring as a result of contact with anthrax-infected animals such as sheep and cattle (6).
Cutaneous Anthrax: the anthrax spores enter the skin through a cut or abrasion, leading to swollen itchy sores on the skin (6).
- Incubation: 1-14 days after exposure
- Symptoms: The lesion presents as a painless, pruritic papule on the exposed areas of the skin. Vesicles may develop. After rupture, black eschar develops.
- Diagnostic testing: Blood culture, gram stain, culture of vesicular fluid. Blood and pleural fluid cultures should be obtained.
Mortality: If left untreated, this infection has a mortality rate of 20 % - Treatment: antibiotic therapy such as penicillin or doxycycline for 7-10 days (6).
Inhalational Anthrax: Develops when anthrax is inhaled through the lungs. T he inhaled anthrax spores travel to the alveoli. Spores can remain dormant up to 60 days (6).
- Symptoms: During the initial phase of inhaled infection, patients may have very unspecific symptoms such as fever, sweats, fatigue, non-productive cough, dyspnea, vomiting, hemorrhagic meningitis and shock.
- Diagnostic Testing: Rapid diagnostic test (nasal swab) should be performed in patients suspected of exposure to anthrax to confirm the diagnosis and determine antibiotic sensitivities. CT scanning should be considered if anthrax is suspected. WBC is typically normal or slightly elevated. Laboratory resources from the CDC can provide confirmatory testing.
- Treatment: Oral or IV antibiotic ciprofloxacin or doxycycline. Anthrasil is a human immune globulin used in combination with antibiotics (6).
- Mortality: 45%.
Gastrointestinal anthrax: This is very rare. This occurs from eating undercooked meat from an infected animal. Symptoms include nausea, loss of appetite, vomiting, and fever (6).
- Incubation: 1-7 days after exposure
- Mortality: 50% without treatment with treatment 40% (6).
- Vaccine for all types of Anthrax: BioThrax (7).
Plague
The plague also known as the “black death,” is caused by Tersinia pestis and has claimed millions of lives throughout history. The plague most commonly presents as the bubonic form but can also appear in sepsis or pneumonic form. There are approximately 10-15 cases of the plague in the United States per year (6).
The most common route of infection in humans involves the transmission of the bacteria following a plague-infected fleabite. Person to person transmission does not occur in bubonic or septicemic plague form. However, pneumonic plague is highly contagious. If the plague is aerosolized as a weapon, it could be extremely deadly (6).
- Incubation: Period: 2-8 days after exposure
- Symptoms: Symptoms present with a sudden onset of fever, chills, weakness, and swollen lymph nodes (bubo).
- Mortality: Pneumonic plague has an almost 100% mortality rate if not rapidly treated with antibiotics
- Treatment: streptomycin, gentamicin, ciprofloxacin, and doxycycline
- Vaccine: There is currently no vaccine (7)
Smallpox
The last reported case of smallpox occurred in 1977 in the United States, and it has two different forms. The deliberate introduction to this highly contagious disease could cause a worldwide pandemic in a matter of weeks (6).
- Incubation Period: 12-14 days
- Symptoms: Symptoms presently abruptly with a high fever, headache, backache, and malaise. Patients will then develop a maculopapular rash on the face. The rash also develops on the palms of the hands and soles of the feet.
- Mortality: 55% with treatment. Almost 100% without treatment.
- Treatment: TYPOXX- is the first drug with an indication for the treatment (6).
- Vaccine: CBER (7)
Tularemia
Tularemia is caused by the bacteria Francisella tularensis. It is also known as the “mild plague”. It is incredibly infectious, and simple contact with a culture plate can result in illness. The bacteria causing tularemia have many natural reservoirs, including rabbits, squirrels, muskrats, and cats. The primary source of infection for humans is domesticated rabbits. Tularemia can present in ulceroglandular, glandular, oculoglandular, oropharyngeal, typhoidal, or pneumonic forms (6).
Person to person contact does not occur. Bioterrorist dispersal could result in many pleuropneumonic cases. Without antibiotics, tularemia would progress to extreme respiratory failure and death (6).
- Incubation: Period: 1-14 days
- Symptoms: The symptom onset is rapid with fever, headache, myalgia, sore throat, nausea, vomiting, diarrhea, and dry or productive cough.
- Mortality: in United States is less than 2%.
- Treatment: aminoglycosides, macrolides, fluroquinolones, and chloramphenicol (6).
- Vaccine: There is currently no vaccine available (7).

Botulinum Toxin
Botulism is caused by Clostridium botulinum, which is a naturally occurring substance in soil. The toxin is derived from a spore-forming bacterium that has neuroparalytic effects. Most cases of botulism result from contaminated food. The most likely bioterrorism action with botulism would include contamination of food and aerosolization. The infection results from the absorption through a mucosal surface, with the intestine absorption being more common than through the lungs (6).
- Symptoms: Initial presentation includes GI upset that rapidly progresses to cranial nerve abnormalities. Progressive bilateral descending paralysis ensures followed by respiratory failure and death.
- Mortality: Less than 5 % if treated but approaches 60% if untreated
- Treatment: Supportive critical care with assisted ventilation, prevention of secondary infection (6).
- Vaccine: Botulism Immune Globulin Intravenous (7).
Viral Hemorrhagic Fever
There have been geographically isolated viruses, including Lassa, Ebola, Marburg, and Dengue that fall into the category of infectious agents for viral hemorrhagic fevers. The vectors of these viruses include rodents, mosquitoes, and ticks. Aerosolization is a more likely mode of terrorist dissemination (6).
- Incubation period: 2-21 days
- Symptoms: Abrupt onset of fever, myalgia, malaise, headache, vomiting, abdominal pain, and diarrhea. A maculopapular rash develops on the trunk, usually within five days. Later clinical symptoms include hepatic failure, renal failure, neurologic deficits, hemorrhagic diathesis, shock, and multi-organ dysfunction.
- Treatment: Treatment is supportive. Ribavirin (Virazole) has shown minimal success in the treatment of patients with hemorrhagic fevers. The CDC has recommended giving this to patients with suspected viral hemorrhagic fever pending final diagnosis (6).
- Vaccine: Ervebo (7)

Chemical Agents
Chemical agents are another type of biological warfare that exists and pose a threat to health and safety. Most chemical agents are liquids that are turned into vapors. When used as a weapon, they could be easily spread by explosion or spray. Chemical agents are extremely toxic chemicals that are lethal or have incapacitating effects on humans (19).
- They are cost–effective
- They may be used at lower levels of concentration to cause panic or disorder
- Chlorine, phosgene, and cyanides are widely used in the process of chemicals or pharmaceuticals
- They can be easily transported in the form of water bottles, cold drink cans, ampules, or pens
- The effect of intentional release varies depending upon the compound’s toxicity, its volatility, concentration, the route of exposure, the duration of exposure, and the environment.
Classification of Chemical Agents
Chemical warfare agents have differing characteristics and belong to various classes of compounds. They are classified in several different ways, but in general, are classified on their physiological effects produced on humans. They are classified as:
Blister Agents (vesicants)
- Inhaled or absorbed through the skin
- They can affect the eyes, airways, skin, and GI tract
- They can cause large blisters that resemble burns (8)
Example: Mustard Gas- If exposed, it can take up to 4-8 hours before experiencing symptoms (13)
Treatment involves lotions, eye drops, and pain medication. If an infection develops, antibiotics can be used (13). There is no antidote for mustard toxicity.
Blood Agents (Cyanogenic agents)
- These are generally inhaled and distributed through the blood
- They do not affect the blood but rather inhibit the production of blood components
- Lead to suffocation from delayed or lack of oxygen transport (12)
Treatment involves oxygen and mechanical ventilation. Treatment aims to dissociate the cyanide ion from the cytochrome oxidase-cyanide complex. This is accomplished by the administration of binders like amyl nitrite, sodium nitrite, and DMAP (14).
Nerve Agents
- Cause hyperactivity of muscles and organs
- Absorbed through skin, lungs, or by liquid or vapor exposure
- Can affect eyes, nose, airways, GI tract, muscles, and CNS (12)
- They are highly toxic and can cause death from a few minutes to a few hours after exposure (19).
Example: Sarin and VX. Exposure can cause interruption of breathing, muscle weakness, loss of consciousness, convulsions, and death (15)
There is no antidote for nerve agent poisoning (15).
Pulmonary Agents
- Inhaled through lungs
- Irritating to airway passages
- In extreme cases, the membranes swell, and the lungs become filled with liquid, and death results from lack of oxygen.
- Chlorine and phosgene are examples of this class
- The treatment of phosgene poisoning is palliative. The objective treatment is the prevention of pulmonary edema and the effects of anoxia. This may involve mechanical ventilation and administration of cortisone and sodium bicarb (16).
Riot-Control Agents
- These are compounds that cause temporary incapacitation by irritation of the eyes (Tearing and blepharospasm) as well as irritation of the upper respiratory tract
- Also known as “tear gas”
The treatment requires immediate decontamination of clothing and eyes (19).
Psychomimetic Agents
- Chemical agents that consistently produce changes in thought, perception, or mood without causing disturbances in the autonomic nervous system or severe disability
- LSD is the most well-known member of this group
- Affected individuals cannot follow a series of instructions or lack concentration
General supportive management of the patient includes decontamination of skin. The most significant risks to a patient’s life are injuries from their erratic behavior (18).
Toxins
- Poisonous chemical compounds synthesized in nature by living organisms such as bacteria, fungi, terrestrial or marine animals.
- There are two groups: Protein toxins and non-protein toxins
- Toxins as agents of warfare are restricted to assassinations or localized terrorist attacks
- The two most crucial toxin threats are botulinum toxin and Staphylococcus Enterotoxins B.
- The treatment for toxins is passive immunization with antitoxins (19).

Radioactive & Nuclear Agents
“A Radiological Dispersal Device (RDD) is any device that causes the purposeful dissemination of radioactive material without a nuclear detonation.” This can be in the form of a “Dirty Bomb” or other dispersal methods. Radioactive Sources can be solid, aerosol, gas, or liquid (20).
- Dirty Bomb = Explosive method of dispersion
- Explosion = radioactive and nonradioactive shrapnel and radioactive dust; radiation contamination, radiation exposure, physical injury, burns, and panic and fear (20).
Other dispersal methods can involve passive or active dispersion of unsealed radioactive sources. For example, dropping them on water or soil or dropping them from an airborne device (20).
A nuclear weapon is a device that uses a nuclear reaction to create an explosion. When a nuclear weapon explodes, it emits four types of energy: a blast wave, intense light, heat, and radiation. Nuclear weapons can be in the form of bombs or missiles (21). The energy to cause a nuclear explosion comes from splitting the two radioactive materials Uranium 235 and Plutonium-239. The bombs that were dropped on Hiroshima and Nagasaki, Japan, in World War II are examples of nuclear explosions.
When a nuclear weapon explodes, it creates a fireball. Within this fireball, everything is vaporized and carried upward, creating a mushroom-shaped cloud. The material within the once vaporized substance cools into dust particles that drop back down to earth, known as fallout. The fallout is radioactive and contaminates anything that it comes into contact with (21).

- What is an example of a Radiological Dispersal Device?
- What are some diverse ways that a Radioactive source can be dispersed as a method of warfare?
- What is the name of the material that was originally vaporized that cools into dust particles that drops back down to earth?
Dangers of a Nuclear Weapon
A nuclear weapon, if used, would cause extreme destruction, death, and injury to a large area. Those close to the blast could experience injury or death from the explosion, burns from the heat and fire, blindness from intense light, and radiation sickness.
People further from the blast but in range of fallout could experience effects of radiation sickness, contaminated food and water, and external or internal contamination from the fallout (21).

Radiation Exposure – Acute Radiation Syndrome (ARS)
Physical Findings Suggestive of ARS:
Vital Signs | Skin | Nervous System | Gastrointestinal | Hematologic |
Fever
Hypotension Tachycardia Tachypnea |
Erythema
Edema Blistering desquamation |
Impaired level of consciousness ataxia
Papilledema Motor/sensory deficit Presence/absence of reflexes |
Abdominal tenderness
GI bleeding |
Bruising
Ecchymosis Petechiae of skin |
*Acute Radiation exposure is the result of a radiological or nuclear incident.
There are four sub–syndromes of Acute Respiratory Syndrome:
1. Hematopoietic
Changes in blood cell counts will reflect the radiation dose. Lymphocytes, neutrophils, red cells, and platelets respond to radiation in different ways. The interpretation of lab values will depend on how long after radiation exposure the lab values were measured. Faster drops in absolute lymphocyte count and the absolute neutrophil count will reflect a higher dose of exposure (11).
2. Gastrointestinal
Nausea and or vomiting can occur soon after the brain, upper GI tract, and whole-body irradiation. Radiation can cause GI mucosal damage and damage to bone marrow elements. Both of these factors can cause GI blood loss. Consider treatment with anti-diarrheal meds, fluid replacement, and antimicrobial agents (22).
3. Cutaneous
Skin changes that occur earliest (hours to weeks) after exposure include erythema, swelling, edema, blistering, and skin sensitivity. Skin changes that could occur later (days to weeks) after exposure include skin desquamation, hair loss, and skin necrosis.
The management of cutaneous radiation injuries must be highly individualized. Management may include: wound debridement, fluid replacement, pain management, use of corticosteroids, antimicrobial therapy, and growth factors to enhance granulation (22).
4. Neurovascular
An increase and decrease in blood pressure and body temperature can occur hours after significant radiation exposure. These changes may reflect clinical infection and CNS irradiation. Fatigue, headache, and anorexia can also happen as well as cognitive and neurological deficits. Consider treatment with glucocorticoids if shock or increased intracranial pressure is present, consider mannitol, control body temperature, and blood pressure, consider CNS imaging (22).

Blast Injury
Primary blast injury can cause extreme barotrauma affecting air-filled organs leading to pulmonary damage, rupture of tympanic membranes, and rupture of hollow viscera (fatal). A secondary blast injury can lead to fragmentation injuries and penetrating trauma. A tertiary blast injury can be caused by structural collapse or people being thrown by blast force wind. This can lead to crushing injuries, blunt trauma, fractures, amputations, and open or closed brain injuries (23).
Thermal/Burn Injury
Thermal burn injuries occur by direct absorption of thermal energy through exposed skin. It can lead to burn casualties, eye injuries, and retinal scarring (23).
Long term effects of radiation:
- Delayed effects of acute radiation exposure
- Specific organ effects depending on where a given isotope is incorporated
- Carcinogenesis
- Mutagenesis (23)
Management of Patients with Radiation Exposure
If you were presented with a patient with potential radiation exposure, here is a list of things to consider:
- Look for early clinical signs and symptoms of Acute Radiation Syndrome (see chart above)
- Use Radiation Bio Dosimetry Tools to estimate whole–body radiation dose (22):
- Obtain CBC with differential and platelet count
- Input absolute lymphocyte counts into Interactive Calculator to estimate whole–body radiation dose
- Repeat CBC every 24 hours if possible, to increase the accuracy of the dose estimate and management
- Consider myeloid cytokines and antibiotics if whole–body dose estimate is ≥ 2 (22).

- What are some of the long-term effects of radiation?
Personal Protective Equipment (PPE)
“Personal protective equipment refers to clothing and respiratory coverings designed to shield an individual from chemical, biological, and physical hazards (24).”
The type of protection required depends on the incident and the duration of exposure that is anticipated. In general, PPE is more effective against chemical agents because biological agent incidents are not likely to be evident until well after the agent’s release (24).
There is a Personal Protective Equipment classification system that is used in describing the varying levels of protection:
Level A | Level B | Level C | Level D |
Provides the maximum amount of protection against vapors and liquids.
This type of protection is full encapsulation in chemical resistant sit, gloves, and boots as well as a pressure-demand, self-contained breathing apparatus. |
Is used when full respiratory protection is required, but danger to the skin from vapor is less.
It requires a non-encapsulating, splash-protective, chemical-resistant suit that provides LEVEL A protection against liquids but is NOT airtight |
Utilizes a splash suit along with a full-faced positive or negative pressure respirator | Limited to coverall or other work clothes, boots, and gloves |
*Information in text box retrieved from Chemical and Biological Terrorism: Research and Development to Improve Civilian Medical Response (24)
Types of Protection
There are several types of protective equipment, each with its own sets of requirements and uses. Listed are the various common elements of PPE (24):
Respiratory:
Appropriate respirators should be used to protect against adverse health effects that may be caused by breathing contaminated air
Eye/Face:
Eye and face protection will protect the user from hazards of potential flying fragments, sparks, or chemical splashes
Skin:
Skin protection should be used if a user has potential exposure to harmful substances
Noise:
Ear protection such as earplugs or earmuffs can prevent hearing damage. Exposure to high noise levels can cause hearing loss or impairment.
PPE Management
PPE requires the implementation of a management program for education and safety purposes. Training for PPE involves the proper mechanics of donning and doffing PPE, the maintenance and care of PPE, the limitations, and the appropriate disposal after use (24).
PPE Specifically for Biological Agents
A terrorist attack of biological agents presents different needs for PPE than a chemical attack agent. Unless there is pre-incident intelligence of a biological agent, a biological attack would be covert (24). Many of the biological agents have incubation times ranging from hours to weeks between exposure and clinical symptoms; if an aerosolized agent had been used, it is likely to have dissipated from the area before recognition of first responders (24).
Apart from smallpox, and plague bacteria, person-to-person transmission of the diseases rarely occur if “universal precautions are maintained (e.g., gloves, gown, mask, and eye protection).” The majority of patients that have been affected by other biological agents can be cared for without specialized isolation rooms or ventilation systems. The hemorrhagic virus infections may be transmissible with blood or aerosol. Therefore, respiratory protection for responders caring for these patients would be required (3).
If pre-incident intelligence puts rescue personnel at the scene of a release, the same PPE they would employ for a chemical incident will protect from biological agents (24).
PPE for Radiation Exposure
In all cases where radiation is suspected, first responders should wear personal radiation dosimeters that allow them to read the dose and or accumulated dose in real–time (20,24).
In the event the first responder is exposed to radiation only even with a high risk of contamination and non-radiation hazards have been excluded, Level C PPE will provide sufficient respiratory and dermal protection. However, in the event a first responder is exposed to a high-risk event of exposure, PPE gives no protection against high energy, highly penetrating forms of ionizing radiation (20).

Syndromic Surveillance & Reporting Procedures
Because of the heightened concern of bioterrorism’s potential possibility in our nation and across the world, public health agencies are currently testing new surveillance methods of early detection of illness resulting from a bioterrorism-related pandemic (12). Unlike traditional systems that utilize voluntary reporting from clinical providers to acquire data, syndromic surveillance continuously acquires data through protocols and automated routines. For example, Washington DC syndromic surveillance system collects emergency department data from hospitals within the area. Based on chief complaints, the system identifies possible high priority bioterrorism agents (15).
Establishing a Diagnosis
Establishing a diagnosis of a potential bioterrorist weapon is essential to a positive and efficient public health response. The diagnosis will guide treatment, medication management, and vaccinations. Diagnosis of a bioterrorist attack can be made through syndromic surveillance or clinical reporting (12).
Through Syndromic Surveillance
Many symptoms of biological weapons present with nonspecific symptoms in the preliminary stages. Patients with these illnesses seek patient care and are more than likely assigned a nonspecific diagnosis such as “viral syndrome.” The data on patients fitting various syndromic criteria is sent to the health department. This process flags a statistical detection threshold that has been exceeded. At this point, Epidemiologists determine if a preliminary investigation is warranted for further evaluation (25).
If they deem further investigation necessary, say, for example, a blood culture is taken from several patients. Within several hours a culture yields a presumptive diagnosis of anthrax, therefore, producing a full-scale public health response.
Through Clinician Reporting
Some patients that have been exposed to a biological agent may have short incubation periods.
Example: A patient is unknowingly exposed to inhalational anthrax. Respiratory distress occurs in this one person and is hospitalized. The patient is routinely admitted to the hospital and blood cultures are drawn. Within several hours a diagnosis of anthrax Is made. The patient’s physician informs the local health department yielding a full-scale response.
Health Alert Network
“The Health Alert Network (HAN) is the CDC’s primary method of sharing information regarding urgent public health incidents with public health information officers; federal, state, territorial, tribal, and local public health practitioners; clinicians; and public health laboratories (25).”
The HAN also collaborates with these groups to develop protocols and relationships that will ensure a solid foundation if the rapid distribution of public health information occurs. The HAN is a national program that provides vital information to state and local levels. The HAN messaging system transmits Health Alerts, advisories, updates, and information services to over one-million recipients (25).
Health Alert Network Message Types (25)
Health Alert | Health Advisory | Health Update | Info Service |
Provides important and time sensitive information for specific incident. It warrants immediate action/attention by health officials, laboratorians clinicians, and public members. HIGHEST IMPORTANCE. | Provides important information for a specific incident. This has recommendations or actionable items to be performed by public health officials, laboratorians, and or clinicians. May NOT require immediate action. | Provides updated information related to an incident or situation; unlikely to require immediate action | Provides public health information; unlikely to require immediate action. |

Suicide in the United States
Having a background knowledge of the risks and statistics of suicide in America is important for ER nurses to have an appreciation of the severity and factors related to suicide.
Prevalence, Incidence, Demographics, and Statistics
One suicide is one too many. Suicide is a tragic event and affects the lives of more than the person who took their own life. It impacts family, friends, associates, and others interacting with the individual. Suicide is beyond a cry for help, as the person believes taking their own life is the only solution to their pain and suffering.
Suicide is the ninth leading cause of death in the United States according to the American Foundation for Suicide Prevention costing $69 billion and the loss of approximately 48,344 lives in 2022 (1). Suicide rates are estimated to be approximately 14.5 per 100,000 individuals (2). From 1999 to 2016, American suicide rates increased by nearly 30%. Risk factors appear to be multifactorial and not always due to a mental health disorder.
Suicide in the United States has been ranked as one of the highest rates among developed nations and increased by 30% between 2000 and 2020, from 10.4 to 13.5 suicides per 100,000 individuals (3). In the top nine leading causes of death among those ages 10-64, there were almost 46,000 deaths in the United States from suicide in 2020, which is approximately one death every 11 minutes (4).
The rate of those who think about suicide is higher than those who carry it out. In 2020, 12.2 million Americans admitted to seriously thinking about killing themselves, 3.2 million planned a suicide attempt, and 1.2 million attempted a suicide, not resulting in death (5, 75). During the COVID-19 worldwide pandemic, depression rates increased three-fold, leading to an increase in suicide rates in the U.S., especially for men of color (6). Mental health became a publicly discussed health issue more than ever during the pandemic.
According to the CDC, firearms account for 50% of suicides in the United States, followed by suffocation (28%), drug poisoning (11%), and non-drug poisoning (3%) (3).
There has been a steady increase in both completed suicide and suicidal ideation in the past decade, possibly due to the increase in the availability of firearms, but also complicated by the stressful lifestyle of modern society. Interestingly, more suicides occur in rural areas than suburban areas, again possibly due to the availability of firearms (74).
The American Psychiatric Association Assessment and Management of Risk for Suicide Working Group explains the risk of suicide increases with the following conditions (35):
- Psychiatric diagnoses: especially mood disorders, psychotic disorders, anxiety disorders, posttraumatic stress disorder, substance use disorders, and disorders associated with impulsivity.
- Medical conditions: particularly those that are chronic, debilitating, disfiguring, or painful.

Definition of Terms
Defining terms related to suicide is important to understand what suicide is, versus suicide attempt and the terms related to self-inflicted death.
Suicide is defined by the Centers for Disease Control and Prevention and accepted as a standard definition as “death caused by injury to oneself with the intent to die” (3).
A suicide attempt is the action of self-harm with the intent to cause death without resultant death.
Suicidal ideation is the continual thinking of self-harm and death but is a broad term describing wishes and preoccupations of death and suicide. Because there is no standard definition for suicidal ideation, it becomes difficult for clinicians, researchers, and educators to identify and even code for it as a diagnosis (7).
Research indicates those with a mental health disorder are at higher risk for both suicidal ideation and eventual suicide, however, one study collected by the Centers for Disease Control revealed that as high as 50% of those who committed suicide had no known mental health disorder (7). Whether those deceased had a mental illness that was not yet diagnosed or not is unknown.
A study in the United Kingdom found that as high as 90% of those who successfully committed suicide had disclosed their suicidal ideation to their primary practitioner and 44% within the month of suicide. This points to the standard policy that a suicide threat should always be taken seriously (8).
The study found that only 22% of those primary care providers believed the threat and suicidal ideation to be a concern as they thought the person would never actually carry out the threat. For all healthcare professionals, this is a huge message and reminder to always take seriously any suicidal ideation of a client.
Imminent harm: An immediate and impending action that will cause bodily harm to self or others is imminent harm. When a client is assessed to be in imminent harm to themself, such as in an emergency department, an emergency legal code may be initiated to legally restrain the person to keep them safe. Each state may have a different code. The factors to consider include the duration of the risk, the nature of the potential injury, and the timeframe before the potential harm would occur.
Lethal: An action that is considered lethal, is sufficient to cause death. When discussing suicide, a legal action would cause the end of life of that person.
Homicide: The deliberate and unlawful killing of another person and is also called murder. Suicide is killing oneself and contrasts with homicide, which is taking the life of another person.
Classifying Levels of Risk
Identifying risk factors for suicide is valuable for suicide prevention. Recognizing which factors lead to suicide helps healthcare professionals classify the level of risk to know which level of action is necessary.
Self Quiz
Ask yourself...
- Identify the definition of suicidal ideation.
- Compare and contrast the definition of suicidal attempt and completed suicide.

- What are methods to determine lethality and suicide risk?
Suicide Risk Factors
Because suicide is multifactorial there are many issues to consider for those that may increase the risk for suicide. There are also protective factors within each category to consider and encourage that may help a person avoid suicidal ideation and behaviors.
Cultural Factors
Culture is defined as the customs, beliefs, behaviors, art, communication style, and dietary habits of a particular group based on ethnicity, race, religion, or even social group (10).
Cultural norms throughout history have had a powerful impact on the individual’s definitions of life, death, wellness, and disease. Historically, in some cultures, self-sacrifice by death could be considered honorable such as the Japanese belief in hari-kari death by disembowelment as a form of seppuku, a ritual suicide.
Suicide by ethnic groups varies with white European Americans having the highest rates, and American Indians and Native Alaskans the highest of ethnic groups (11).
Research also reveals that motivations towards suicide vary among different ethnicities. Latinx or Hispanic individuals were more likely to commit suicide for external stressors such as job loss, divorce, abuse, or discrimination, compared to their white counterparts who cite internal feelings of hopelessness and worthlessness (12). Ethnic minorities often demonstrate more feelings of hopelessness due to discrimination and racism, which puts them at risk for suicidal ideation and suicide (13).
Within culture there is a religious influence among people for their interpretation of the act of suicide. In Christian groups, suicide is considered one of the highest acts against God and is a sin. Other religions may consider suicide as the passing of this one life with a negative consequence for the reincarnation of the next life. Inherent in most cultures however is the sanctity of life and abhorrence of suicide, which in Hindu is termed soul-murder.
Culturally sanctioned doctor-assisted euthanasia is found in some European cultures and is acceptable only for terminal illnesses (13). Interviews with women after a suicide attempt reveal their feelings of not belonging to either culture as their adolescent experience is vastly different from their parents in the country of origin and they feel neither their parents nor peers understood them.
This research revealed that depression may not be the only emotion before a suicide attempt but additionally feelings of anger. Whereas the typical white male will commit suicide with firearms, and have access to them, a younger ethnically diverse population may attempt suicide with hanging or over-the-counter medication overdose demonstrating anger turned within.
Healthcare professionals need to recognize the impact and influence of culture and religion on an individual’s mental health and behaviors, which may either increase or protect against suicidal ideation and behaviors. Application for clinicians is to consider cultural implications along with the generic suicide risk tool that is being used.
Recognizing that Asian and Latinx Americans are generally motivated by external factors and white European Americans may be more motivated by internal factors can help guide the clinician to inquire about life factors that may impact depression, mental health, anxiety, and suicidal ideation.
Sometimes the culture itself may create feelings of shame such as the Asian culture of “saving face” versus the shame of letting parents or the general culture down. Some Asian cultures place great emphasis on excelling academically and if a child chooses not to study the topic directed by the parents, or doesn’t have the academic interest or aptitude, the child may experience deep shame and stress (15).
Protective factors within culture for an individual include feeling a sense of community within their culture. Following cultural norms and expectations appears to be protective as those who commit suicide are described as living without the boundaries of the culture such as being isolated and deviant.
Protective factors for any culture appear to be a sense of connectedness and purpose in life. Some people who still experience feelings of worthlessness or hopelessness may still find protection from feeling connected to their culture, family, an individual, or divine responsibility to honor the sanctity of life (13). Teaching traditional values and spirituality within the culture is a protective factor for youth (16).
Geographic Factors
Research shows geographic factors that matter in the incidence and prevalence of suicide.
Those in rural areas, including Veterans, have a higher incidence of suicide, which may be due to the availability of firearms (17). The only exception to that locality factor is African American males who have an increase in suicide in urban areas.
Living in rural areas may also promote social isolation, barriers to access to medical care for counseling and mental health treatment, and dangerous work conditions such as in farming communities. In addition to living in isolated areas, such as rural communities, geographic factors include living in negative and dangerous or disturbing neighborhoods in urban areas.
Protective factors include programs that help recognize people in isolated rural communities. Veteran programs can be helpful to those in rural areas who choose more isolated areas but can still promote a sense of community and belonging.
Telemedicine has been extremely helpful during the COVID-19 pandemic in delivering mental health and general medical care to people in isolation even in urban areas and can be used more in rural settings. The trend of embracing telemedicine during and after the pandemic has helped improve access to healthcare despite poor or no insurance. Sometimes people who have used telemedicine and screened positive for suicide risk are directed to an emergency department, where ER nurses can continue the screening and crisis management.
Economic Factors
External environmental factors such as unemployment and poverty play a role in despair. Areas with people below the poverty line and those who are unemployed do have an increased rate of suicide (18). Eviction and home foreclosure also increase the risk of suicide. Interestingly, a significant worsening of financial status was more significant as a risk towards suicidal ideation than chronic poverty (19).
Poor economic status also contributes to the lack of resources for mental health counseling and medications. The application for healthcare professionals is to assess the individual’s ability to afford psychiatric medications including simple SSRIs.
Protective factors could include robust financial resources, but suicide occurs even among wealthy or economically stable individuals.
Home and Family Factors
Family dynamics and a sense of belonging are key factors that can be either contributors to suicidal risk or protective factors (20). Even when a person may have a sense of family, they may still have a belief that they don’t want to be a burden, which can outweigh the home and family support, as seen in elderly suicide or those with terminal illnesses.
Studies reveal that the perception of a hostile home environment, criticism, invalidation, and lack of support for life choices increases suicidal ideation and behaviors of not just youth but adults (21, 22). Because suicide attempts are 20 times greater than completed suicide, interviews from persons who attempted suicide reveal family disharmony, parental divorce or arguments, sibling conflicts, and lack of support as factors that contributed to their sense of urgency to disappear from life.
Family factors also include a family history of suicide. Physical and genetic predispositions to mental health may be involved, but also important are the pattern of poor stress management and dysfunctional interpersonal dynamics. A history of physical, emotional, or sexual abuse, including incest, is a sign of dysfunctional family dynamics. A recent family loss and difficulty grieving can also be a risk factor.
Adverse childhood events (ACEs) accelerate mental health disorders and despair and create negative health outcomes in adulthood (23). The key message for healthcare professionals is to consider family dynamics beyond the individual at risk for suicide. Family intervention and group counseling and support may be needed in addition to the individual attention given for more effective risk management.
Protective factors for home and family include the strength and support a person may feel within a family unit. A sense of validation for their existence by loving family members is powerful. If an individual has mental health disorders or chooses an alternative lifestyle, support and understanding are protective against feelings of isolation and hopelessness.
Mental and Emotional Health
Studies reveal that although mental health disorders are found in approximately 50% of those who commit suicide, it is not a consistent factor for all cases of suicide. The more specific mental health issues include intrapersonal thoughts of a persistent sense of hopelessness, worthlessness, shame, guilt, meaninglessness, and a feeling trapped with no way out (24). Those with a sense of loneliness, separation, isolation, and feeling unloved, or rejected have an increased risk of suicidal ideation and behaviors (24).
In completing suicide screening tools, researchers have noticed that some people will skip the question of previous suicide attempts leading to a false conclusion of lower risk. Significance for clinical personnel is to review the entire instrument for completion before scoring.
Although depression is a recognized precursor to suicide it is not the only factor and is not always present. (23). Screening for depression in all individuals ideally should be done but screening is not adequate if there are no solutions or resources for the person, which could make the depression worse by creating a sense of hopelessness.
It is estimated that up to 18 million adults and 7% of the adult population have depression at any time (25). According to the American Society on Aging, up to two-thirds of elder suicides were related to untreated or undiagnosed depression. Not everyone who has depression should be placed in restraints and confinement for protection. Some screening instruments have fallen out of use after not being able to demonstrate valid and reliable identification of risk factors, such as the SAD screening tool (9).
Protective factors include strong mental and emotional health, but that is difficult for anyone to stay consistent all the time. Life itself is inherently difficult but the concept of resilience is key. Can you bounce back from a bad day within a short period, or do you linger in a state of despair or negative emotions? The ability to be resilient through life’s difficulties is key.
Mental health status and emotional strength can either increase suicide risk or add protection.
Depression
Depression is unfortunately a common emotion and is seen in at least 10% of adults at any time in the United States. Depression is a condition that follows and is interlaced with other health conditions such as the following (36). Depression is the most common mental health disorder as the issues of perceived isolation, hopelessness and lack of purpose are reported for those with suicide attempts and completed suicide.
Conditions that often correlate with depression:
- Cancer: 25% of cancer patients experience depression.
- Stroke: Up to 27% of post-stroke patients (more than 1/4 of all stroke patients) experience depression.
- Heart attack: 1 in 3 attack survivors experience depression.
- HIV: Depression is the second most common mental health condition of those with HIV.
- Parkinson’s Disease: 50% experience depression.
- Eating Disorders: approximately 33-50% of clients with anorexia have a comorbid mood disorder, such as depression (37).
- Substance Use Disorder: Over 20% of Americans with a mood disorder, including anxiety or depression have an alcohol or substance use disorder.
- Diabetes Mellitus: approximately 1/3 of all people with diabetes experience depression (Holt, et al, 2014).
- Polycystic ovary syndrome (PCOS): 20% of women with PCOS experience depression. (38).
Each of these conditions creates an additional risk of dissatisfaction with life and self-harm. Recognizing the prevalence of depression in the adult population is a call for healthcare professionals to screen all patients with simple questions for suicidal ideation.
Physical Factors
There are interesting theories based on physical factors that may impact the brain’s ability to think clearly and avoid self-harm. One theory proposes that low cortisol levels are seen in people who commit suicide, which may represent a lack of natural fight-or-flight response to stress. Low cortisol levels were found in the family history of suicide or suicide attempt. Lower than normal cortisol levels were also found in those who reported suicidal ideation. (26).
Another physiologic-based theory shows that microglial cells, found in activation of inflammation and stress are found concentrated in the prefrontal cortex of those who committed suicide. Excess microglial cells affect the concentration of neurotoxic waste products compared to neuroprotective metabolites (27).
Glutamine is a dietary amino acid related to mood and sense of well-being and inflammation may also cause alterations that may contribute to a lack of cognitive flexibility, increased impulsivity, poor memory, depressed mood, and suicidality (28).
There is emerging interest in identifying any genetic mutations that may increase the risk of suicidal ideation. Several studies have identified that gene mutations in families of those with increased incidence of depression include variants of the FKBP5 gene (29).
Risks for suicide are multifactorial and the research continues as suicide for any person and family is devastating.
Social Factors
Social isolation, feelings of not being socially accepted, or socially significant such as immigrants or ethnic minorities, are at risk for suicidal ideation and behaviors. The social construct is also related to culture as it involves interpersonal relationships.
Evidence shows that education, social status, and employment play an important role in suicidal ideation and behavior. Social factors include being male, unemployed, a lone person in a household, and divorced, widowed, or separated are strongly associated with death by suicide (30).
Protective social factors involve positive interpersonal relationships. Healthcare primary care providers, such as nurse practitioners, can refer individuals at risk for individual and group counseling and resources to develop improved emotional intelligence and interpersonal skills.

At-Risk Populations
Identifying at-risk populations comes from demographic information about the incidence and prevalence of suicide in the United States. Statistics reveal important information about the increased risk for some individuals, which is worth recognizing. Health departments and national organizations can better create prevention and education programs based on this data.
For example, knowing that Veterans in rural areas are at increased risk of suicide due to isolation and poor access to mental health resources allows Veteran agencies to better accommodate those needs, which has been helpful. As noted in the above-listed risk factors several population groups have been recognized to be at greater risk.
Gender
There is a higher incidence of suicide among males worldwide compared to females. Studies reveal that although the incidence of suicide is low in white males over age 75, those men who do attempt suicide have higher success rates. It is estimated 40 per 100,000 men over age 75 will commit suicide. Gender makes a difference as to the means of committing suicide.
When men attempt suicide, it is with more lethal and violent means such as with guns and ropes. Women over age 75 have much lower rates of 4 per 100,000 and are often less successful with suicide efforts and commonly use less lethal methods such as drug overdose attempts. Women are twice as likely to attempt suicide but when men have greater completion rates than women.
Age
The risk of suicide affects people differently in different age groups. There are two age groups with an increased incidence of suicide which include young adults from 25-34, and again a surge in reported attempts and completed acts in the elderly from age 75-84.
Adolescents with any of the above risk factors of depression, mental health disorders, race, dysfunctional family situation and substance use are at greater risk of suicide.
“During 2019, approximately one in five (18.8%) youths had seriously considered attempting suicide, one in six (15.7%) had made a suicide plan, one in 11 (8.9%) had made an attempt, and one in 40 (2.5%) had made a suicide attempt requiring medical treatment” (31).
According to the Suicide Prevention Center, suicide was the second leading cause of death for youth ages 10 to 14, and adults ages 25 to 34 in 2020. Suicide was the third leading cause of death for people ages 15 to 24, the fourth leading cause of death for ages 35 to 44, and the seventh leading cause of death for ages 55 to 64 (32).

Race
Ethnic groups with the highest rates of suicide and suicidal attempts are people of color, non-Hispanic whites, and native American Indians. Race, ethnicity, and culture were discussed earlier.
Diagnosis of Substance Use Disorder
Individuals with substance use disorders (SUD) are at a significantly greater risk of suicide for both males and females than those who don’t partake of addictive substances (72). Most research connecting substance use disorders with suicidal ideation and behaviors was conducted with Veterans, but another study examined the general population and found similar results (72). Using multiple substances is extra risky. Alcohol substance use disorder was the most common substance in the historical use of suicide attempts and completed suicide.
It is acknowledged that SUD and mental health disorders often are seen together. It is understood that the SUD condition is often an effort to deal with difficult mental health issues, family, and social issues and even loneliness and despair. When the combination of SUD and mental health disorders is not treated effectively, individuals often see suicide as a viable way to “make it all go away.”
The key message for healthcare professionals is to increase screening for substance use disorders. Using the Substance Use Brief Intervention and Referral to Treatment (SBIRT) method of asking simple screening questions should be done at each client interaction.
Military and Veterans
According to the National Veteran Suicide Prevention Annual Report, there are approximately 6000 veteran suicides annually, and 22 veteran suicides each day. The rate of suicides among this unique population is 1.5 times greater than the rate of non-military and veterans (33).
The Veterans Affairs Department (VA) recognizes the incidence of post-traumatic stress disorder (PTSD) among veterans who have served in the military and offers free services and education for prevention. Online website training, smartphone apps, and free counseling are available for veterans, healthcare professionals, and families.
In examining factors that contribute to the increase in suicide among our veterans several contributors have been identified. Transitioning out of the military and into civilian life is the most delicate time as military personnel often struggle to find their new routine and job, culture, new interpersonal relationships, often physical pain from injury, and new purpose (33 The first year of transition has been called “the deadly gap.”
Studies confirm that human beings crave a sense of belonging, which many veterans identify with in their military service. Once they leave that association, they often find a culture gap and few people understand what they may have experienced in war and military service. Veteran suicides represent almost 14% of all suicides even though their population as a group only represents 8% of the adult population (34).
Substance Use Disorder is also a contributor to the veterans’ population which compounds their risk for suicidal ideation and possible suicide (72). Many contributors to this increased risk have been explored such as risk-taking behavior personality that may have drawn them into the military initially, the use of substances to deal with traumatic military experiences, and the skill of firearms. The following diagram depicts these factors for our veterans.
(33)
Our veterans deserve the best medical and psychological care for their service to our country. The role of healthcare professionals, especially primary care providers, is to offer effective screening and education of resources that are available. A challenge is the limited knowledge many medical professionals have about veterans’ resources, which can be difficult to navigate.
Diagnosis of Mental Illness and PTSD
Although it has been assumed all those who commit suicide have a mental health disorder, statistics show only 50% of those who commit suicide had a diagnosed mental health disorder at the time. In contrast, according to the Psychiatric Association Practice Guidelines for Psychiatric Evaluation of Adults, as high as 90% of people who commit suicide meet the diagnostic criteria for one or more mental health illnesses (35).
Healthcare Providers
A unique population at risk for suicidal ideation and behaviors are the very professionals the general population relies on for healthcare when they are in a suicidal crisis. The emotional and often physical stress of the healthcare job itself can place workers at risk.
Healthcare workers face a unique set of obstacles that increase the risk of suicide. Their demanding nature, long hours, high-stress levels, and exposure to trauma all combine to exacerbate vulnerability, increasing suicide risks. Healthcare providers also endure emotional strain when managing patient suffering and ethical dilemmas while striving to provide optimal care within resource-constrained settings.
As mental illness is still perceived with great stigma in healthcare communities, individuals seeking help for mental health problems might avoid seeking assistance altogether, leading to underreporting and untreated issues of this nature. These factors combine to put healthcare professionals at an increased risk for suicide compared to the general population.
A study in the Journal of American Medical Association revealed physicians to have significantly higher suicide rates compared to general populations, underscoring the critical need for targeted interventions and support systems in healthcare industries to combat this significant threat (77).
Suicide among nurses was publicized more during the worldwide COVID-19 pandemic when nurses and healthcare workers functioned with little sleep between shifts, managed without adequate personal protective equipment, and stood by the bedsides of dying patients on ventilators that couldn’t survive the initial onslaught of the mysterious virus and worked despite fears of exposing their own family and loved ones.
The PTSD they experienced was influenced by feelings of hopelessness when no matter what they did could not stop the fatal power of the virus. Tragically the caregivers in trauma and critical care units often experience PTSD themselves, which we know is a risk factor to suicidal ideation.
Nurses are in a unique position to add mental health screening questions to the intake form of their patients. Likewise, taking time for self-care has become not only acceptable but a popular statement of permission to do what we should have been doing all along: healing the healers.
LGBTQIAS2+ Population
This unique population has been at increased risk for suicide due to the essential elements found in those with suicidal ideation and behaviors such as hopelessness for acceptance, often lack of family support, and lack of customized health resources.

Special Populations at Risk
Youth and Suicide
Suicide in youth most occurs between the ages 13-21 (69). Suicide by gender also reveals that teen girls from 12-19 are the highest incidence. Thankfully, suicide under the age of 5 is difficult to find in research and statistics. Risk factors include the lack of support and resources, or perceived by the teen, to help them address life’s challenges of critical decisions, high expectations at home, school, athletics, or anything of a competitive nature.
Mental health disorders are found in 90% of teen suicides. The most common disorder is depression. Other common disorders include anxiety and eating disorders that create distress for the individual. About 33% of suicides were proceeded by a suicide attempt or call for help.
As high as 50% of teens who committed suicide had a family member with a mental health disorder. It is supposed that the youth was modeling the maladaptive behaviors seen in the home. Divorce, violence in the home, and negative interpersonal relationships outside the home, such as a romantic breakup, have a great impact on young minds and can become fatal when they are not taught problem-solving skills.
Veterans and Military Personnel
A unique population at risk are our veterans and military personnel due to the added violence they have been exposed to and access to lethal means. Screening should be done by primary care providers, but that means the provider must be aware of their military history and service. Veterans Affairs has created extra programs after recognizing their unique added risk.
Suicide and the COVID-19 Pandemic
Not only did the coronavirus, known as Covid-19, cause the death of millions worldwide, but it created a never-before seen burden on healthcare workers who were exposed to the virus themselves, as they cared for dying patients. The rates of mental health distress, depression and anxiety soared among healthcare workers, which led some to suicide in an often-hopeless environment without adequate personal protective equipment and effective therapies.
It is estimated that in 2020 Covid-19 affected 213, 237, 126 individuals worldwide pending adequate reporting, and result in 4,452,903 deaths including some healthcare professionals.
(70). Those numbers continue to change and still increase each month.
As the burden of new mutations of Covid, including the BA.5 subvariant, take their toll on our vulnerable populations, the nursing shortage has worsened across America. A projected shortfall of 44,500 nurses is estimated by 2030 based on the current workforce and estimated need in hospitals. In the past two years exhausted nurses have left the bedside leaving gaps in direct patient care and facility administrators scrambling for compassionate and competent healthcare workers. Even nurses loyal to the profession have changed their bedside role.
A silver lining through the Covid-19 pandemic has been the new awareness of mental health challenges and stress among healthcare workers. Because of devasting suicides among “our own” more attention to the emotional resilience and well-being of our workers began. Hospitals and administrators began offering counseling, services, and screening.
Much is still needed but at least we as professionals have begun to recognize the healing of our professionals. Just as nurses are taught the risk factors and signs for suicide risk in the general population, we are now being taught to recognize those same signs in our colleagues including irritability, depression, truancy on shifts, appearance of disinterest and just going through the motions at work. Healthcare workers are also at greater risk for substance use disorders due to the increased stress of work and accessibility to medications and mind-altering substances.
Elderly and Suicide
Worldwide suicide rates show that increasing in age increases the risk of suicide, especially of those with chronic disease, or living alone. In the United States, assisted suicide is not a legal option, yet those who experience loneliness after a spouse dies, or have no family members to rely on are at increased risk for self-harm to end it all.
Primary care providers can follow up with care screening questions to identify risk factors. The challenge is always having the time in the insurance reimbursement squeeze of time. Offering seniors access to community services to prevent loneliness such as interest groups or those offered through accountable care organizations in your community can be helpful. Case managers have a unique role as well in being able to make routine phone calls to assess for risk and provide resources.

ER Suicide Screening and Assessment
Generally, the first medical professional in the hospital the individual will encounter after a suicide attempt is an ER nurse. The ER nurse is in a unique position to approach the person with compassionate and competent care.
Nurses deliver unconditional care and compassion for patients who are hurting both physically and emotionally. It is often the nurse who serves as the advocate for the patient by providing resources and communication with the family. A careful screening and assessment of all patients for suicide risk is important, especially in the ER as ER nurses encounter a large cross-section of individuals needing immediate help.
The Interview Process and Asking about Safety
Nurses, nurse practitioners, and healthcare workers can improve the ability to identify those at risk for suicidal ideation and behaviors with appropriate and effective screening questions. Often when a provider is unsure about a suspicion for the client’s risk of suicide, completing an objective screening tool can help clarify the risk factors and client’s mental state.
Just by taking this continuing education course, the topic of suicide and recognition of those at increased risk hopefully becomes forefront in your mind. A screening tool beyond a checklist is more valuable and allowing privacy for a client to complete the assessment is also valuable to get genuine responses. This assessment can be completed ideally in an emergency department by the nursing staff.
Screening Tools
The Joint Commission's NPSG 15.01.01 now requires healthcare professionals to use a validated tool to assess suicidal risk for all patients with reasons for seeking healthcare is the treatment or evaluation of a behavioral health condition (40).
When using a suicide risk tool in an emergency department, those patients who were ambivalent about living had a double increased risk of suicide and those with active suicidal ideation who had active thoughts and plans of suicide had a three-fold increase in probability of suicide within 30 days (41, 73).
Various screening tools and instruments exist and may be used differently in a primary care office setting versus an emergency department.
The most common screening tools used in office settings are:
- P4 Screener: a 4-question screening tool that asks the “4 P’s” of past suicide attempts, a plan, probability of suicide, and preventive factors (42).
- PHQ-2 Patient Health Questionnaire 2: this is a simplified 2-question screening for those at risk for harm to themselves or others. (43).
- PHQ-9 Patient Health Questionnaire 2: this is the 9-question version of the PHQ-2.
- Columbia-Suicide Severity Rating Scale (C-SSRS): questionnaire to assess suicidal behavior and reveal suicidal ideation for pediatrics to adults (44).
The most common suicide risk screening tools used in emergency departments with strong validity and reliability include:
- Ask Suicide-Screening Questions (ASQ): a 4-question screening tool for pediatric & young adults who present with medical complaints. It is recommended to administer without the parent/guardian being present.
- Manchester Self-Harm Rule (MSHR): uses 4 questions to identify the ED patient's risk of suicide or repeating self-harm based on their history.
- Risk of Suicide Questionnaire (RSQ): a 4-question screening tool suitable for 8 years through adult; it takes 90 seconds to complete.
The Joint Commission has approved these additional screening instruments as valid and reliable:
- Beck Hopelessness Scale (BHS): a 20-item questionnaire measuring pessimism and hopelessness (7).
- Beck Scale for Suicide Ideation (BSI): a 21-item self-report instrument for detecting and measuring the current intensity of the patients’ specific attitudes, behaviors, and plans to commit suicide during the past week. The first 5 questions can be used as a screening tool (50).
- Scale for Suicide Ideation-Worst (SSI-W): a 19-item rating scale that measures the intensity of patients’ specific attitudes, behaviors, and plans to commit suicide at the period when they were the most suicidal. It takes 10 minutes to complete (7).
- Death/Suicide Implicit Association Test (IAT): developed by Harvard to test implicit thoughts towards death and suicide.
- Geriatric Suicide Ideation Scale (GSIS): a 30-item questionnaire assessing suicidal ideation on a Likert scale and customized for ages 65+ (45).
- Nurses Global Assessment of Suicide Risk (NGASR): useful for new nurses in completing a clinical assessment.
- Scale for Suicidal Ideation (SSI): a classic 19-item questionnaire for clinicians or self-ratings (paper or computer-based).

Recognition of Warning Signs
Unfortunately, despite decades of research to identify possible risk factors of suicide, there is no one clear profile person or set of behaviors that reliably identify a suicidal personality. The conclusion from numerous studies is that suicidal thoughts and behaviors are due to a complex interaction of psychological, biological, environmental, interpersonal, and cultural factors. (46)
Unlike physical conditions that be assessed and identified visibly or with diagnostic instruments, the emotional components of suicidal ideation are complex and there is no one single screening instrument that is always reliable. What research does conclude is that by using any screening tool, and with the genuine sincerity of the practitioner, someone at risk may feel safe enough to open up.
The approachability and authentic compassion of the provider is a key factor in a client honestly expressing suicidal thoughts. Unfortunately, many healthcare providers are working with tight time constraints and limited client interaction, especially in urgent care settings. Practitioners working in a primary care office setting may also not even consider a client is at risk for suicide when the primary chief complaint is something common or mundane.
In one study, five categories of identifying factors should be assessed to identify those at risk for suicidal ideation or behaviors.
Effective suicide screening instruments should assess these components (47).
- Internal psychopathology (e.g., anxiety disorders; mood disorders; hopelessness; emotion dysregulation; sleep disturbances)
- Demographic factors (e.g., age; education; employment; ethnicity; gender; marital status; religion; socioeconomic status)
- Prior suicidal thoughts and behaviors (e.g., prior deliberate self-harm, non-suicidal self-injury, suicide attempt, suicide ideation)
- External psychopathology (e.g., aggressive behaviors; impulsivity; incarceration history; antisocial behaviors; substance abuse)
- Social factors (e.g., abuse history; family problems; isolation; peer problems; stressful life events)
Studies have identified common thought patterns of those who begin to entertain suicidal thoughts as when people perceive themselves to be a burden and don’t have a sense of belonging. These negative thought patterns begin to overcome the instinct of fear of death (48). When a person’s negative thought processes dwell on non-existence, it is said they develop the capability to die.
Repeated exposure to negative events and thoughts perpetuates the feelings of being burdensome and not belonging. If emotional pain is greater than connectedness and purpose the risk of suicide becomes greater.
The feeling of hopelessness was key, and an important concept for healthcare professionals to assess. Using standardized tools to assess for the lack of purpose, belonging, and hope are the critical concepts to assess and screen for.
The concern is that there is no one perfect screening tool, and results vary based on the provider’s personal prejudices, time constraints by the provider and the medical team to assess and address risk factors, cultural considerations of the client, cognition of the client, and current management of mental health disorders (49).

Assessing Lethality
After recognizing risk factors and warning signs, a nurse should assess the lethality and possibility of fatal actions by the client. Some warning signs may actually be indicative of depression and not a true risk for self-harm, however other behaviors may be indicative of a fatal act.
Death or survival depends on various risk factors that affect the degree of lethality. When completing a lethality assessment, three parts should be considered including 1) the degree of planning for suicide, 2) the potential of perceived lethality by the person, and 3) the accessibility to the means to carry out the desired action (51).
A suicide inquiry examines the ideation, plan, behavior, and intent of the client. Assessment tools ideally should be culturally appropriate and continue to be developed yet take time. Although many people have suicidal thoughts, not all will move forward to lethal actions.
It is important to recognize that suicidal thoughts can also move across a spectrum so the client with same risk factors may be at higher risk pending environmental and mental health triggers. Recognizing which risk factors can be modified is also important for a provider when making interventions and recommendations.
Identifying protective factors have not been as researched as risk factors but according to the National Center for Injury Prevention and Control, Division of Violence Prevention has identified the following such as effective clinical care, access to healthcare and interventions, support from medical professionals and family members, problem solving skills, and cultural and religious beliefs that discourage suicide (52).
Levels of Risk
Completing the screening survey is just one step, however, the practitioner needs to identify the score and level of risk. Just documenting the risk assessment score is not adequate. A meta-analysis study revealed that despite recognizing of warning signs and clear risk factors on an assessment, 95% of those did not commit suicide however 50% of those who did were in the low-risk categories (53). Perhaps less important than a score is to truly assess the client’s physical behaviors and emotional affect, and then take appropriate actions.
It is important to distinguish between active and passive suicidal ideation. Active suicidal ideation is when a person has a conscious desire for self-harm and death as a result. The means of inflicting death should not be the key focus, but rather the thought process and person’s expectation that their attempt could be fatal is the primary concern (54).
An example of an active suicidal ideation assessment item is the Modified Suicidal Ideation Scale (Miller et al, 1991) which asks questions such as:
- "Over the past day or two, when you have thought about suicide, did you want to kill yourself? How often? A little? Quite often? A lot? Do you want to kill yourself now?"
Examples of passive suicidal ideation assessment items include:
Scale for Suicidal Ideation (SSI) with questions to measure "passive suicidal desire.”
- 0 = Would take measures to save [one's own] life
- 1 = Would leave life/death to chance
- 2 = Would avoid steps necessary to save or maintain life
European Depression Scale (55) that asks:
- "In the past month, have you ever wished you were dead?"
Documenting Suicide Risk
Documenting suicide risk must be done as always after a provider’s visit, as in any documentation of a visit. The name of the risk screening tool and score should be included in the notes, along with interventions for safety and client/family education.

Healthcare Provider Training
Due to the continual high rates of suicide and suicide attempts, more effective suicide prevention strategies are needed. Ideally, if we knew exactly how to prevent suicide, there would be no more suicides, however the reality is much more complicated. Several ideas have been proposed including better training for practitioners to screen and interview effectively, and to reduce access to firearms (56).
The Joint Commission has issued recommendations for healthcare professionals and primary care providers to do the following before a client leaves an appointment or the ER:
- Review each patient’s personal and family medical history for suicide risk factors.
- Screen all patients for suicide ideation using a brief, standardized, evidence-based screening tool.
- Review screening questionnaires before the patient leaves the appointment or is discharged.
- Act based on the assessment results to inform the level of interventions needed (40).
Teaching family members and friends to support someone in a suicide crisis requires clear guidance (75).
Healthcare professionals can begin the public awareness of how to help such as the following actions:
- Talk openly and honestly. Don’t be afraid to ask questions like: “Do you have a plan for how you would kill yourself?”
- Remove means such as guns, knives, or stockpiled pills.
- Calmly ask simple and direct questions, like “Can I help you call your psychiatrist or counselor?”
- If there are multiple people around, have one person speak at a time.
- Express support and concern
- Don’t argue, threaten, or raise your voice.
- Don’t debate whether suicide is right or wrong.
- Try to model calmness in your own body.
- Be patient with the person.
- Use the phrase “It’s safe for you to share your feelings with me because I care about you.”
- Let the person know there are healthcare professionals who can help them with their thoughts.
Recognition of Warning Signs
According to the National Alliance on Mental Illness, recognizing warning signs and behaviors of someone about to commit suicide include the following:
- Increased alcohol and drug use
- Aggressive behavior
- Withdrawal from friends, family, and community
- Dramatic mood swings
- Impulsive or reckless behavior
- Collecting and saving pills or buying a weapon
- Giving away possessions
- Tying up loose ends, like organizing personal papers or paying off debts
- Saying goodbye to friends and family

Treatment and Management of Clients at Risk
Treatment and management of clients at risk for suicide is based on the unique risk factors and needs of the individual client. Several strategies including different therapies have been studied and are available.
Medical Management of Mental Illness
According to the National Institute of Mental Health (NIMH) as high as 46% of those who committed suicide had a mental illness (2). Management of clients with mental illness is one important treatment strategy. When clients with mental illness are not treated appropriately with effective pharmacological management or counseling, the risk of suicidal ideation increases.
The concerning mental health issues include intrapersonal thoughts of a persistent sense of hopelessness, worthlessness, shame, guilt, meaninglessness, and a feeling trapped with no way out (12). A combination of depression, anxiety, or psychological disorders can compound the feelings of hopelessness. Research shows that both pharmacological treatment and cognitive behavior therapy for mood disorders including depression and bipolar disorder, which are among the most common disorders in the world, have better outcomes than either strategy alone (61).
Currently, antidepressant medications used for mood disorders include monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants. In the past two decades, the more commonly prescribed agents that block the reuptake of serotonin, norepinephrine, or dopamine known as selective serotonin reuptake inhibitors (SSRIs) and serotonin/noradrenaline-reuptake inhibitors (SNRIs) (62).
Cognitive Behavior Therapy (CBT) has been the most researched therapy for the treatment of mood disorders and shows statistically significant improvements in mood for participants. ER nurses can also help patients obtain access to mental health services in their community. Knowing and sharing which mental health services are available is a way of advocating for patients experiencing depression and stress.
Management of Substance Abuse
As substance use disorder is associated with an increase in suicide risk, the ER nurse should screen for substance use. Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based practice used to identify, reduce, and prevent problematic use, abuse, and dependence on alcohol and illicit drugs (5). The SBIRT model is the practice of having healthcare professionals, from physicians, nurses, nursing assistants, medical assistants and any medical person who interacts with patients, screen for substance use and abuse. If the patient’ screen is positive, the healthcare professional refers them to available programs and community resources. SBIRT is an early and brief intervention of screening questions and takes less than 5 minutes. An additional history, physical exam, and clinical diagnosis of substance abuse disorder take an additional 10-20 minutes. The time for asking screening questions and offering resources is billable to Medicare/Medicaid. The screening and referral to treatment includes a patient encounter, history, physical exam, clinical diagnosis, and plan for care specific to the concern of substance abuse.
A key aspect of SBIRT is the integration and coordination of screening, early intervention, and treatment components into a system of care. The link between substance uses and suicidal ideation has been documented (5).
It is estimated that a person with a substance abuse addiction must be asked at least 10 times by a healthcare professional before they even move towards contemplation in the behavior change process. You may be person #2 or #10 but it takes screening without judgment, in the spirit of help and coaching to move a person forward to begin to consider substance use. Many people in a substance abuse pattern want to stop but don’t know how or what their resources are.
Simple questions to begin with include “Do you smoke?” If yes, then ask about the frequency of daily consumption and years smoked to calculate pack years. The next important question is simply to ask if they have a desire to stop smoking. If the answer is yes, then you can offer programs and resources. If the answer is no, then let them know you are concerned about their health and you are available with resources when they’re ready to stop.
Each time you have a patient encounter, simply go through the same questions and eventually the person may begin to be in the contemplative stage of change. For alcohol and illicit drug use using the CAGE format is an acronym to help you remember to ask certain questions.
Many people with a substance use disorder may feel like they are in a CAGE and just need help to get out.
C: Have you ever felt you needed to Cut down on your drinking? ...
A: Have people Annoyed you by criticizing your drinking? ...
G: Have you ever felt Guilty about drinking? ...
E: Have you ever felt you needed a drink first thing in the morning (Eye-opener) to steady your nerves or to get rid of a hangover?
Learning how to become comfortable with asking the screening questions takes practice and you can overcome any hesitation you may feel that you are prying into their personal life by practicing simple questions. Asking the screening questions is a strong start and then referring clients to effective resources for cessation and recovery is the next important component of SBIRT.
You need to learn what resources are available in your community such as free Alcoholics Anonymous meetings and groups, and more. A simple Google search is a good place to start. There are also many free national resources such as the 1-800-quit-now phone lines that will offer resources to individuals seeking help.

Suicidal ER Admission
ER nurses play a strong role in caring for a patient being admitted after a suicide attempt, one who verbalizes a high threat of suicide, and those who screen at risk for suicide.
When patients who have attempted suicide arrive at an ER for evaluation and admission, several critical steps must be followed to ensure their safety and provide appropriate care. Initial assessment takes place in the triage area where a nurse assesses and prioritizes care based on the severity of injuries sustained and mental health status.
Nurses working in triage play an invaluable role in quickly recognizing patients in need of immediate medical assistance, particularly those at risk of further harm or worsening health conditions.
After receiving reports from paramedics regarding any attempted suicide attempts and methods used in attempts, as well as interventions taken en route to hospital care, the nurse gathers pertinent details to share with the provider.
This report aids emergency room physicians and clinicians with their evaluation and treatment plan. Following triage and initial assessment, the nurse conducts a full physical exam on the patient to assess physical health issues because of attempted suicide as well as any injuries from the attempt (78).
This assessment includes vital signs monitoring, wound examination, and neurological testing to detect trauma or intoxication symptoms. Nurses conduct mental health evaluations to detect any psychiatric conditions or risks and assess an attempter's suicide risk.
Safety must always come first when caring for such individuals. Nurses work closely with hospital security to create an atmosphere conducive to patient safety and staff wellbeing. Security measures implemented may include continuous observation of patients and removal of potentially hazardous objects from the area near them; in addition to maintaining a calm, supportive atmosphere in the emergency department (ER).
Working closely together between nurses and security staff is vital to effectively address safety concerns and avoid additional injury. Security staff may assist in de-escalating volatile situations and assuring physical safety for both patients and others in the emergency setting.
Together with nurses and security personnel, nurses and security personnel can manage admission processes for those who have attempted suicide efficiently and compassionately while offering comprehensive emergency care in this setting.
Labs and Diagnostic Tests
Healthcare providers assessing suicidal patients in medical settings typically order laboratory and diagnostic examinations to evaluate physical health issues, identify any underlying medical conditions, and assess any self-inflicted injuries sustained during evaluation. These tests may differ based on an individual patient's presentation, medical history, and clinical judgment.
Some common lab and diagnostic tests that might be done for someone post-suicide attempt or in an acute suicide crisis include (80):
- Full Blood Count (CBC): This provides detailed information regarding red and white blood cell counts, platelet count, and hemoglobin levels of an individual patient. Abnormalities in these parameters could indicate serious medical conditions like infection, anemia, and other blood disorders.
- A Comprehensive Metabolic Panel (CMP) measures various organ function markers including electrolyte levels, kidney, and liver enzyme levels such as creatinine urea nitrogen ratios as well as liver enzyme activity including Alanine Amitransferase, Aspartate Amitransferase levels as well as glucose concentration levels.
- Urinalysis: Urinalysis evaluates both physical and chemical characteristics of urine samples to detect metabolic imbalances or organ dysfunction, including any trace amounts of blood, proteins, glucose, or abnormal cells present. Urinary tract infections, kidney dysfunction, or metabolic disorders may all be detected using simple labs and then a simple ultrasound.
- Drug Screening: Toxicology screening may also be conducted if substance abuse or overdose is suspected. This process typically includes clinical interviews, standardized assessment tools, and collaboration between mental health providers.

Legal and Ethical Issues with Suicide
Even with the best intentions to help people at risk for suicide, there are legal and ethical issues to consider. Privacy and the right to choose are still key concepts in our society. ER nurses are the frontrunners in seeing the legal side of protecting patients often against their will. When a patient is brought into the ER after a suicide attempt or threat of suicide, the admitting provider may write an order for a 72-hour emergency hold. This is about the legal statute that a person may be held against their will if they are deemed a threat to themselves or others.
Ideally ER admission for suicide should include a safe and compassionate environment, however, most emergency departments (EDs) lack the facilities, staff or expertise required to respond appropriately when dealing with mental health emergencies. Furthermore, most EDs tend to be noisy and disorganized environments unsuitable for de-escalating behavioral health crises. Retrofitting emergency departments to handle behavioral health and suicidal patients is expensive for many hospitals.
Even with adequate funding in place, psychiatric patients frequently experience more stigma and bias when receiving emergency care, including being made to undress without privacy as they may be placed in a hallway for easier monitoring, prolonged boarding times, and minimal therapeutic support during that period (79). ED patients generally don't benefit from much therapeutic assistance during that time. Basic needs like showering, brushing teeth, using the phone, and eating can be extremely challenging for psychiatric patients in ER settings.
An emergency department mental health evaluation does not aim to initiate or provide even short-term mental healthcare but to assess an individual's risk of self-harm (80). Such assessments only consider admission or discharge requirements without providing recommendations for actual treatments or recommendations to manage conditions that have arisen during evaluations.
As part of an overall suicide risk screening in an emergency department (ED), brief screening for suicide risk has limited sensitivity in identifying which patients pose the highest risk. However, low-risk patients can still be identified, and those in which psychiatric holds and real-time psychiatric consultation while in the ED may no longer be necessary allowing more expeditious discharge from the ED.
The role of the ER nurse in admitting a suicidal patient is a careful and delicate one due to the potentially lethal outcomes if a patient is discharged unsafely. Suicidal patients may be admitted into a psychiatric unit where security is provided at a higher level and psychiatric consultations are given. Ideally, the patient will be able to receive further assessments and referrals for appropriate services. Unfortunately, an ER nurse may never know the outcome of their careful attention to the suicidal patient, but knowing the nurse did all possible within their scope can still help. ER nurses can make a difference by becoming more active in public legislation for safe facilities for mental health patients, improvements in hospital policy development and staffing, and effective use of existing screening tools.

Case Study Continues
Due to careful and compassionate care from an emergency room nurse, Chad, the 27-year-old male who was brought into the ER after a suicide attempt was admitted and provided with appropriate psychological evaluation and referral for counseling services. After arriving at the emergency department following an attempted suicide attempt, he was met with kindness from a dedicated nurse.
Recognizing how urgent his condition was, she swiftly coordinated his admission process, so he received immediate medical care. With compassion and professionalism, the nurse conducted a detailed assessment, covering both physical and mental aspects of her patient's illness. Once stable, he continued receiving support from the nurse as his condition stabilized over time.
Recognizing the necessity for psychological evaluation and counseling services, the nurse collaborated closely with the healthcare team to facilitate the transition of the patient to appropriate mental health resources. The nurse advocated on behalf of his patient's needs, making certain he received follow-up care and support to address mental health concerns and reduce future self-harm risk. Through careful intervention and a compassionate approach by this ER nurse, the patient felt heard, understood, and supported during a vulnerable moment in his life.
With access to comprehensive mental health services as well as ongoing support services available at his disposal, his journey toward recovery was enabled thanks to a compassionate ER nurse who made such a significant difference when needed the most.

Conclusion
Suicide remains one of the leading causes of death in the United States. Risk factors have been identified and solutions proposed. Various prevention strategies include mental health awareness, public awareness for suicide prevention and detection, addressing limited access to lethal weapons, addressing unique concerns for high-risk sub-groups such as offering school-based resources for youth, educating healthcare primary care providers as the gatekeepers, staffing crisis hotlines, and promoting more free counseling services with legislation and tax funds.
Suicide is a complex issue and there are no single solutions. It will continue to require a multifactorial approach that addresses the cultural, economic, political, social, and religious factors. Every effort as a Nurse Practitioner to truly connect with your patients, provide screening, and offer real resources, is a life that may be saved.
Nevada HIV: Stigma, Discrimination and Bias
Introduction
One of the toughest challenges faced by people living with HIV is social stigma and discrimination. As we go through this course, please imagine a close family member or friend was recently diagnosed with HIV and you are comforting them with this life-changing news. Education is a powerful tool to reduce this stigma, as myths and inaccurate information continue to exist.
Overview of Human Immunodeficiency Virus (HIV)
Human immunodeficiency virus (HIV) is the virus that can destroy or impair immune system function and lead to acquired immunodeficiency syndrome (AIDS), which is known as the most advanced stage of HIV infection (14).
Etiology
This virus is unevenly distributed among races and genders.
- 39 million people globally were living with HIV (in 2022).
- 37.5 million adults
- 1.5 million children
- 53% of all people living with HIV were female.
- 1.3 million people became newly infected with HIV in 2022.
- Roughly 630,000 people died from AIDS-related illnesses or complications in 2022.
- At the end of December 2022, only an average of 76% of all people living with HIV were accessing antiretroviral therapy.
- 9.2 million people living with HIV did not have access to antiretroviral treatment in 2022.
- AIDS-related mortality has declined by 55% among women and girls and by 47% among men and boys since 2010.
HIV prevalence among the adult population is roughly 0.7% (15). However, it is much greater in certain populations. Populations that face the greatest impact include sex workers, homosexual men who are sexually active with men, those who inject illicit drugs, transgender individuals, and those in prison (15).
Pathophysiology
The virus attaches to the CD4 molecule and CCR5 (a chemokine co-receptor); the virus' surface fuses with the cellular membrane to enter into a T-helper lymphocyte (7). After integration in the host genome, the HIV provirus forms and then goes through transcription and viral mRNA production. HIV proteins are then produced in the host cell and can release millions of HIV particles that have the potential to infect other cells (7). This leads to the destruction of the cell-mediated immune (CMI) system, primarily by eliminating CD4+ T-helper lymphocytes, which are vital to this system.
- Acute HIV infection: Describes the period immediately after infection with HIV when an individual has detectable p24 antigen or has HIV RNA without diagnostic HIV antibodies.
- Recent infection: Describes the 6 months following infection.
- Early infection: This may refer to acute or recent infection.
Stages of HIV
Those who do not receive treatment typically progress through three stages. However, HIV treatment can slow or prevent progression of the disease. Significant advances in HIV treatment have led to such slowed progression that Stage 3 (AIDS) is less common now than in the early years of HIV.
Stages of HIV (4):
- Stage 1: Acute HIV Infection
-
- There is a large amount of HIV in the blood, making the virus very contagious.
- Flu-like symptoms are common.
- It is important for those who have symptoms and/or possible exposure to get tested.
- Stage 2: Chronic Infection
-
- Also called asymptomatic HIV infection or clinical latency.
- HIV is still active and continues to reproduce in the body.
- People may not have any symptoms or get sick during this phase but can transmit HIV.
- People who take HIV treatment as prescribed may never move into Stage 3 (AIDS).
- Without HIV treatment, this stage may last a decade or longer or may progress faster.
- Stage 3: Acquired Immunodeficiency Syndrome (AIDS)
-
- The most severe stage of HIV infection.
- Possible high viral load and high likelihood of transmission.
- People with AIDS have badly damaged immune systems. They can get an increasing number of opportunistic infections or other serious illnesses.
- Without HIV treatment, those in Stage 3 (AIDS) typically survive about three years.

Symptoms
Many patients may be asymptomatic following exposure and infection. The average time from exposure to onset of symptoms is 2 to 4 weeks, although in some cases, it can be as long as 10 months.
A constellation of symptoms, known as an acute retroviral syndrome, may appear acutely. Although none of these symptoms are specific to HIV, their presence of increased severity and duration is an indication of poor prognosis.
These symptoms are listed below (7):
- Fatigue
- Muscle pain
- Skin rash
- Headache
- Sore throat
- Swollen lymph nodes
- Joint pain
- Night sweats
- Diarrhea
Complications
A complication of HIV disease is its progression to acquired immunodeficiency syndrome (AIDS). AIDS occurs when lymphocyte count falls below a certain level (200 cells per microliters) and is characterized by one or more of the following (7):
- Tuberculosis (TB)
- Cytomegalovirus
- Candidiasis
- Cryptococcal meningitis
- Cryptosporidiosis
- Toxoplasmosis
- Kaposi sarcoma
- Lymphoma
- Neurological complications (AIDS dementia complex)
- Kidney disease
If not treated, HIV can have profound effects on the brain and brain function. Individuals living with HIV should be screened for neurocognitive impairment in a clinical setting, with support for management and neurorehabilitation.
HIV is highly transmissible during acute infection; rapid initiation of antiretroviral therapy (ART) reduces transmission and early viral suppression to preserve immune function. Essentially, healthcare workers must recognize the significant clinical benefits of early detection for the individual with HIV.
Removing barriers (such as stigmas) to seeking testing and treatment = LIFE

Ask yourself...
- What are examples of complications of HIV?
- How would you explain the importance of early detection to a patient?

Antiretroviral Therapy (ART)
Antiretroviral Therapy (ART) has transformed the prognosis of HIV from being a condition with declining health that leads to certain death, to a manageable long-term condition, with an expectation of good health and associated quality of life lifespan similar to the non-HIV population.
Clinical Management of HIV
When HIV infection is diagnosed, immediate care is crucial. ART dramatically reduces HIV-related morbidity and mortality, and viral suppression prevents HIV transmission.
The following recommendations support clinical decision-making (6):
- Clinicians should recommend antiretroviral therapy (ART) to all patients diagnosed with acute HIV infection.
- Clinicians should inform patients about the increased risk of transmitting HIV during the acute infection phase and for the 6 months following infection in patients who choose not to begin ART.
- As part of the initial management of patients diagnosed with acute HIV infection, clinicians should:
-
- Consult with a care provider experienced in the treatment of acute HIV infection.
- Obtain HIV genotypic resistance testing for the protease, reverse transcriptase, and integrase genes at the time of diagnosis.
- Patients taking post-exposure prophylaxis (PEP): When acute HIV infection is diagnosed in an individual receiving PEP, ART should be continued pending consultation with an HIV care provider.
- Patients taking pre-exposure prophylaxis (PrEP): The risk of drug-resistant mutations is higher in patients who acquire HIV while taking PrEP, so clinicians should consult with an experienced HIV care provider and recommend a fully active ART regimen.
The clinicians should implement treatment to suppress the patient’s plasma HIV RNA to below-detectable levels (6).
The urgency of ART initiation is even greater in the following individuals:
- Pregnancy
- Acute HIV infection
- 50 years and older
- Presence of advanced disease
For these patients, every effort should be made to initiate ART immediately, ideally on the same
Studies suggest that nearly 25% of all people living with HIV are not accessing antiretroviral therapy. HIV prejudice, unfair stigmas, discrimination, and bias likely correlate with this finding.
Counseling
Communication and interaction immediately following the initial diagnosis of HIV is critical for an ongoing therapeutic relationship. Empathy, compassion, confidentiality, trust, and hope should be paramount. Remember to explain that HIV treatment has dramatically changed the prognosis and future of those living with HIV and emphasize that life can continue very close to the way it did before, while also emphasizing the importance of beginning medication.
A reactive HIV screening result should prompt a care provider to counsel the patient about the benefits and risks of ART and HIV transmission risk, including the consensus that undetectable equals untransmutable (U=U).
Patient education and counseling include:
- Confirming the diagnosis of HIV
- Managing disclosure (if indicated)
- Adhering to the ART regimen
- Communication with the care team to address any potential adverse effects of medications or other concerns
- Clinic visits
- Case management for medications required for lifelong therapy
- In-depth education on ART; including pharmacy selection, insurance requirements and restrictions, copays, and refills.
- Psychosocial support management
- Referring to substance use and behavioral health counseling (if indicated)
- Assessing Health Literacy

The Devastation of an HIV Diagnosis
Those living with HIV have a completely different story and a very different approach to how they see and think of their HIV status. Several studies have documented and analyzed the psychological impact of an HIV diagnosis. It is meaningful to take a moment and focus on perspectives upon receiving a diagnosis of HIV from actual individuals who have dealt with this experience.
Bella shares, “When I got diagnosed with HIV in March 2008, I was totally devastated and felt that my whole world had been blown apart.”
Jack explains, “Close friends, family, anybody, even new people that I’d meet, I just felt that I couldn’t, I suppose I felt quite, quite worthless because I didn’t have the, [sighs] I felt like I’d lost something, I just found everything so tiring, I didn’t have anything to give, I didn’t feel that I had anything worthwhile to kind of contribute, I don’t know, I was just kind of like shell shocked I suppose.”
“A found poem” has been constructed from the interview transcript of Noelly:
"What Really Stands Out” poem by Noelly (5)
Themes emerged from the studies. A key theme developed in the analysis of the experience of receiving a diagnosis of HIV was ‘unwelcome and problematic changes in identity.’ Essentially, a separation of their lives into who they were, then following the diagnosis, who they are now (5). These individuals living with HIV often feel they have lost their previous identity and are now defined by this disease.
To compound this devastation, these individuals are further isolated by unfair treatment, discriminatory practices, and bias. Stigmas and discrimination impact patients in their quality of life with HIV through social isolation, stress, emotional coping, and denial of social and economic resources.
HIV-related stigmas are often associated with psychological distress, including depression, anxiety, and suicidal ideation. Furthermore, stigmas in healthcare settings are considered one of the major barriers to optimal treatment for those with HIV or AIDS. Numerous studies suggest that experiences of HIV-related stigmas resulted in lower access to HIV treatment, low utilization of HIV care services, poorer antiretroviral therapy (ART) adherence, and thus poorer treatment outcomes (12).
The majority of HIV-related stigma research and theory is based on Goffman’s (1963) work. According to Goffman, stigma can be defined as “an attribute that links a person to an undesirable stereotype, leading other people to reduce the bearer from a whole and usual person to a tainted, discounted one” (12).
Imagine this label of “tainted” or “discounted” was applied to your loved one or yourself. Reflect on the emotions you may experience. Would it be anger, hopelessness, or confusion? Isolation and psychological distress will most likely follow this experience of discrimination.
A helpful model for breaking down the impact of HIV stigma includes the four dimensions:
- Personalized stigma
- Concerns about sharing status
- Negative self-image
- Concern with public attitudes about people with HIV
Stigmas are said to challenge one’s humanity. Stigmas are significantly studied within social psychology. Research has aimed to understand the mechanism by which categories are constructed and linked to stereotyped beliefs, and which stigmas generate and perpetuate health inequities.
A major goal is to dismantle the stigma that continues to be significantly troublesome for people living with HIV today, encouraging proper healthcare access and treatment.

Defining Stigma, Discrimination, and Bias
A stigma is an attitude or belief that places a mark of disgrace associated with a particular circumstance, quality, or person (9). HIV stigmas are negative attitudes and beliefs about people who have acquired HIV. The stigma is a prejudice that comes with labeling an individual as part of a group that is believed to be socially unacceptable.
Here are a few examples:
- Believing that only certain groups of people can get HIV.
- Making moral judgments about people who take steps to prevent HIV transmission.
- Feeling that people deserve to get HIV because of their choices.
- Believing that those living with HIV have a morality issue.
Stigmas occur at multiple levels, including interpersonal, institutional (health organizations, schools, committees, and workplaces), community, and legislative levels.
There are different ways in which HIV-related stigmas can manifest. Stigmas have cognitive, affective, and behavioral manifestations. The stigma is associated with a deviation from a constructed ideal or expectation and can often result in the unfair and unjust treatment of an individual based on their HIV status.
The unjust treatment that manifests from a stigma is known as discrimination. Discrimination takes many forms, including isolation, ridicule, and physical and verbal abuse.
Bias occurs when prejudices influence outcomes and decisions (9). This can manifest as denial of services and employment based on HIV status rather than equality or merit.
The mechanism for these processes is based on societal patterns and dominant cultural beliefs in which the undesirable difference is identified and located in an individual or group; these differences amongst people are articulated and labeled as either good or bad. Labeled individuals experience status loss and discrimination that leads to unequal outcomes (e.g. health, economic, social).
Myths about HIV
The spread of myths and false information about HIV must stop for the stigma surrounding HIV to dissipate. The myths have continued to spread regardless of the evidence and research that disproves them. Those in the healthcare field can have a meaningful impact on providing education to all individuals and refute misconceptions.
Myth #1: HIV is a “death sentence”.
Truth: With proper treatment, individuals living with HIV can live a normal life span (11). “Since 1996, with the advent of highly active, antiretroviral therapy, a person with HIV with good access to antiretroviral therapy (ART) can expect to live a normal life span, so long as they take their prescribed medications,” says Dr. Amesh A. Adalja, a board-certified infectious disease physician and senior scholar at the Johns Hopkins Center for Health Security (10).
Myth #2: HIV can be easily spread by casual contact.
A recent survey found the following inaccurate responses and beliefs about the transmission of HIV:
- It can be transmitted by kissing
- It can be transmitted by spit/saliva
- It is spread only among homosexuals
- It is spread by mosquitoes
- It can be transmitted by toilet seats
- It can be transmitted through urine
- It can be transmitted by sharing utensils, cups, and plates.
Truth: HIV is only transmitted by coming into direct contact with certain body fluids from a person with HIV who has a detectable viral load.
These fluids include:
- Blood
- Semen (cum) and pre-seminal fluid (pre-cum)
- Rectal fluids
- Vaginal fluids
- Breast milk
For transmission to occur, the HIV in those fluids must enter the bloodstream of an HIV-negative person through the following:
- A mucous membrane (rectum, vagina, mouth, or tip of the penis)
- Open cuts or sores
- Direct injection (from a needle or syringe)
Myth #3: If someone has sex with an individual with HIV, the virus will automatically be transmitted.
Truth: Individuals living with HIV who take HIV medication as prescribed and maintain an undetectable viral load will not transmit HIV to their HIV-negative partners.
Myth #4: Those living with HIV cannot safely have children.
Truth: HIV can be transmitted from a mother to her baby during pregnancy, birth, or breastfeeding. This is called perinatal transmission. This is the most common way that children get HIV. However, if a woman with HIV takes the medications as prescribed throughout pregnancy and childbirth and gives HIV medication to her baby for 4 to 6 weeks after birth, the risk of transmission can be less than 1% (4).
Testing all pregnant women for HIV and starting HIV treatment immediately has significantly lowered this occurrence.

Forms of Discrimination in Healthcare
Discrimination includes many different actions, attitudes, and behaviors. It is not simply a negative interaction but can come in the form of HIV testing without consent, refusal of care and treatment, and breach of confidentiality. It also comes in the form of irrational self-protection measures that communicate a fear of this person.
Universal Precautions for Care
Imagine how you would feel if every encounter with you, someone applied an unreasonable amount of Personal Protective Equipment (PPE) to come near you. Would this make you feel as if they viewed you as “contagious” or “contaminated”? This act is not only unnecessary but also disrespectful and demeaning.
The evidence-based approach recommended is referred to as "universal precautions." Universal precautions are a standard set of guidelines to prevent the transmission of bloodborne pathogens. Blood and body fluid precautions should be consistently used for ALL patients, including those with HIV. Unless a condition or situation requires additional PPE, universal precautions should be followed in the same manner as it would with any patient (3).
Guidelines for Universal Precautions (3):
- All healthcare workers should routinely use appropriate barrier precautions to prevent skin and mucous membrane exposure when in contact with the blood or other body fluids of any patient.
- Gloves should be worn for touching blood and body fluids, mucous membranes, or non-intact skin of all patients, for handling items or surfaces soiled with blood or body fluids, and for performing venipuncture and other vascular access procedures.
- Gloves should be changed after contact with each patient.
- Masks and protective eyewear or face shields should be worn during procedures that are likely to generate blood droplets or other body fluids.
- Gowns or aprons should be worn during procedures that are likely to generate splashes of blood or other body fluids.
- Hands should be washed immediately after gloves are removed.
- Take precautions to prevent injuries caused by needles, scalpels, and other sharp instruments or devices during procedures
- Healthcare workers who have exudative lesions or weeping dermatitis should refrain from all direct patient care and from handling patient care equipment until the condition resolves.
- Isolation precautions should be used as necessary if associated conditions, such as infectious diarrhea or tuberculosis, are diagnosed or suspected.
Breach of Confidentiality
Patients with HIV may mistrust medical providers’ handling of their medical information which is a reason for them not to utilize health services and treatment. Essentially, the fear of compromised confidentiality can lead to becoming reluctant to seek HIV testing and counseling. This impacts the health outcomes of those living with HIV and impacts the community as a whole.
All members of the healthcare team must protect confidential information. Examples of breach of this duty include the following:
- Accessing confidential information, in any form, without a "need to know" to perform assigned duties.
- Leaving confidential information unattended in a non-secure area.
- Disclosing confidential information without proper authorization.
- Discussing confidential information in the presence of individuals who do not have the need to know to perform assigned duties.
- HIV status should never be relayed to anyone who is not directly involved in their care. An example would be if the nurse told another nurse that their patient had HIV, but this nurse was not involved in their care.
- Improper disposal of confidential information.
- Disclosing that a patient or employee is receiving care (except for authorized directory purposes).

Federal and Nevada State Laws Regarding HIV Discrimination
HIV criminalization is a term used to describe laws that criminalize otherwise legal conduct or increase the penalties for illegal conduct based on a person’s HIV-positive status.
HIV criminalization for potential exposure is largely a matter of state law. Federal legislation addresses criminalization in discrete areas, such as blood donation and prostitution. These laws vary as to what behaviors are criminalized or what behaviors result in additional penalties. Several states criminalize one or more behaviors that pose a low or negligible risk for HIV transmission.
In 2021, Nevada reformed their HIV criminal laws to reflect evidence rather than irrational fear.
SB 275 repeals NRS 201.205, which is an HIV-specific criminal offense with a penalty of up to ten years in prison and replaces it with a misdemeanor offense. The misdemeanor offense has the following restrictions:
- Requires intent to transmit, conduct likely to transmit, and actual transmission.
- This applies to the intentional transmission of any communicable disease
- If someone uses means to prevent transmission or if the individual subject to transmission knows the defendant has a communicable disease, knows conduct could result in transmission and consents.
Other changes to Nevada’s law include:
- Repeal of the category-B felony for engaging in or soliciting prostitution after a positive HIV test.
- Repeal of mandatory HIV testing provisions for individuals arrested for prostitution, arrested for a sexual offense, or coming into the custody of the Department of Corrections.
- Amendments to provisions regarding testing for communicable diseases following incidents in which first responders come in contact with bodily fluids.
- Repeal of a provision permitting confinement of persons living with AIDS
- Removal of many stigmatizing references to HIV and AIDS in the public health code.
- Amendments regarding the duties of individuals living with communicable diseases and public health officials’ authority to order testing, treatment, isolation, or quarantine.

Ethical Principles in Healthcare: Autonomy, Beneficence, Non-Maleficence, Justice
Did you know that the nursing profession is the leading trusted profession for honesty and ethics, and has sustained the title for 20 consecutive years (16)? This speaks volumes and should speak to our humanity in the fight to end HIV stigmatization.
Ethical principles should guide nurses to uphold the trust placed upon their shoulders. The topic of nursing ethics is broad, complex, and evolving. The American Nurses Association (ANA) developed a code that serves as a foundation for ethical nursing practice. The code consists of seven ethical obligations and nine provisions that outline the ethical responsibilities of nurses.
7 Ethical Obligations
The 7 ethical obligations within the AMA’s Code of Ethics for Nurses:
- Accountability
- Justice
- Nonmaleficence
- Autonomy
- Beneficence
- Fidelity
- Veracity
Accountability is considered a priority among the ethical principles in nursing. Accountability is when a nurse is responsible for their own choices and actions in the course of patient care. Each nurse is responsible for any inherent bias and cannot place blame on society or cultural norms.
Justice refers to fair and impartial care, as treating each patient fairly, regardless of their circumstances, is essential to better patient outcomes.
The following factors should never result in partiality or lower standards of care:
- HIV Status
- Age
- Race
- Sexual orientation
- Ethnicity
- Religion
- Socioeconomic status
9 Ethical Provisions
These provisions can individually apply to the treatment of those living with HIV:
American Nurses Association (ANA) Code of Ethics for Nurses: 9 Ethical Provisions | |
Provision 1 | “The nurse practices with compassion and respect for the inherent dignity, worth, and unique attributes of every person.” |
Provision 2 | “The nurse's primary commitment is to the patient, whether an individual, family, group, community, or population.” |
Provision 3 | “The nurse promotes, advocates for, and protects the rights, health, and safety of the patient.” |
Provision 4 | “The nurse has authority, accountability, and responsibility for nursing practice; makes decisions; and takes action consistent with the obligation to promote health and to provide optimal care.” |
Provision 5 | “The nurse owes the same duties to self as to others, including the responsibility to promote health and safety, preserve wholeness of character and integrity, maintain competence, and continue personal and professional growth.” |
Provision 6 | “The nurse, through individual and collective efforts, establishes, maintains, and improves the ethical environment of the work setting and conditions of employment that are conducive to safe, quality health care.” |
Provision 7 | “The nurse, in all roles and settings, advances the profession through research and scholarly inquiry, professional standards development, and the generation of both nursing and health policy.” |
Provision 8 | “The nurse collaborates with other health professionals and the public to protect human rights, promote health diplomacy, and reduce health disparities.” |
Provision 9 | “The profession of nursing, collectively through its professional organizations, must articulate nursing values, maintain the integrity of the profession, and integrate principles of social justice into nursing and health policy.” |

Reducing Stigmas and Discrimination
At this point in the course, we invite you to reflect on your own experiences and recognize any bias toward those with HIV. We will apply a technique from cognitive behavioral therapy, identify a thought or concept, challenge its truthfulness, and then dismantle false conceptions.
Education and Training
Healthcare employees, HIV prevention researchers, and service providers should receive formal education in their academic programs and their workplaces to learn how implicit bias influences the practice of medicine and impacts outcomes. Training should effectively develop skills to reduce negative behaviors and mitigate negative outcomes associated with these biases. Institutions and organizations should also develop and implement initiatives to identify disparities and inequities in their services and practices.
The Power of Language
Language has been a central theme in efforts to dismantle the stigma around HIV (8). When healthcare providers write or speak about HIV, the words they choose have the power to passively maintain ignorance and bias. However, they also have the power to convey respectful and accurate representations and perspectives on those living with this condition.
You may be inadvertently using stigmatizing language, so it is imperative to recognize this harmful language, stop using it, and join in the effort to reduce its use by others.
Let's Talk about it!
Speaking about HIV should not be taboo. The more a topic is discussed, the more it becomes normalized. Talking openly about HIV provides opportunities to correct misconceptions and help others learn more about HIV. Remember to be mindful of how you talk about HIV and people living with HIV. Discussions can be in-person or online; locations can include family, friends, support group members, workplace interactions, social media, and blogs. Get comfortable with saying things like “I was HIV tested and it was a very simple process”.
Educating children and young people to understand how stigmas are formed and operate can help dismantle the continuation of stigmas surrounding HIV.
The Power of Community
Studies show that individuals with strong social support are less likely to feel stigmatized than those who are isolated. If you notice someone is uncomfortable seeking comfort from friends and family, encourage them to contact their local public health department to find HIV support groups within the community.
The HIV Prevention Trials Network developed the LOC Community Engagement Program (CEP) which supports community advisory structures such as Community Working Groups (CWGs) and site Community Advisory Boards (CABs) to represent the participant community. These groups can raise research-related issues or concerns that may impact the participants, community, or study.
Using a cognitive behavioral therapy approach to understand relationships between thoughts, feelings, physical responses, and coping behaviors can be helpful.
Promoting individual-level coping skills and group-based social support focused on the following:
- Decreasing negative feelings toward self and others living with HIV
- Increasing planned and strategic HIV sharing with others and building supportive
- Networks to reduce fears and feelings of rejection
- Building skills to address HIV-related discrimination and other forms of stigma.
Advocacy and Policy
Reducing the stigma associated with HIV is critical for improving public health outcomes, encouraging individuals to seek testing and treatment, and supporting those living with HIV. An interprofessional approach can lead to meaningful change.
Early access to treatment and adherence to the treatment regimen reduces susceptibility to opportunistic infection associated with AIDS and increases life expectancy. To maintain this, clinical treatment guidelines that outline compassionate and unbiased delivery modes of health, treatment, and psychosocial support are required. Healthcare workers play a vital role in this process.
Here are some effective strategies that healthcare workers can use to reduce HIV stigmas:
- Education to Counter Myths and Misconceptions
- Provide accurate information to patients, communities, and even colleagues about HIV transmission, prevention, and the reality that an HIV diagnosis is a manageable health condition.
- Debunk Myths: Actively challenge myths and misconceptions about how HIV is transmitted. Clarify that it cannot be spread by casual contact such as shaking hands, sharing dishes, or hugging.
- Empathy and Nonjudgmental Care
- Show Genuine Empathy: Use supportive and empathetic communication, which is essential for making patients feel valued and understood.
- Avoid Judgment: Practice nonjudgmental care and treat all patients with the same level of compassion and professionalism, regardless of their HIV status.
- Confidentiality and Privacy
- Ensure Confidentiality: Strictly adhering to confidentiality laws and regulations regarding privacy will build trust and encourage patients to seek and continue treatment.
- Respect Privacy: Discuss sensitive information privately and discreetly to prevent inadvertent disclosure.
- Encourage Inclusive Language
- Use Appropriate Language: Employ language that is respectful and free from stigmas.
- Correct Stigmatizing Language: Gently correct peers and patients when they use stigmatizing language, explaining why it is considered harmful.
- Visibility and Public Advocacy
- Promote Positive Representation: Support and promote stories and data that highlight the normal and productive lives that people with HIV lead.
- Engage in Advocacy: Participate in public speaking, media interviews, or social media campaigns to advocate for people living with HIV and to educate the public.
- Professional Development and Training
- Engage in regular training on the latest HIV research, treatments, and approaches to care that emphasize dignity and respect.
- Cultural Competence: Train in cultural competency to better understand and address the diverse backgrounds and experiences of patients with HIV.
- Support Networks and Resources
- Provide Resources: Offer information about local support groups and other resources that may help individuals with HIV feel supported and less isolated.
- Encourage Social Support: Promote engagement with community networks which can provide practical and emotional support.
- Integrate HIV care with other health services to normalize treatment and reduce the isolation of HIV-specific services.
- Peer Involvement: Include peer counselors who are living with HIV in the care team to provide relatable experiences and hope.
By adopting these strategies, healthcare workers can significantly reduce the stigma surrounding HIV and improve both the mental and physical health outcomes for people living with HIV. This not only helps in managing the disease but also integrates support for individuals into everyday life, promoting a more inclusive and compassionate healthcare environment.

Conclusion
As we conclude our exploration of discrimination in the context of HIV/AIDS, we reflect on the profound lessons learned and the pressing challenges that remain. Throughout this course, we have examined the multifaceted nature of stigmas and discrimination—its roots, its manifestations, and the devastating impact on individuals and communities. Discrimination against people living with HIV/AIDS is not only a violation of human rights but also a significant barrier to effective HIV prevention, treatment, and care.
Through education, advocacy, and policy change, we can challenge misconceptions, change negative behaviors, and foster an environment where all individuals, regardless of their HIV status, are treated with dignity and respect. Let us take forward the call to action to advocate for inclusive policies, promote HIV awareness, and support the ongoing fight against the stigma.
End of Life Process
Introduction
Have you ever cared for someone who was dying, known someone who was in hospice, or just wondered what happens as we die? What exactly does “end of life” refer to? End of life is a broad term, and its meaning can vary from person to person. End of life is a time when death is approaching, usually in a matter of days.
This occurs in various patients experiencing a variety of ailments including end stage cancer, dementia, chronic diseases, and someone who may have organ failure after an accident (3).
Oftentimes, caregivers have little to no experience in caring for a patient experiencing the end-of-life process and can easily find themselves feeling overwhelmed, confused, and burned out. Understanding what to expect during the final weeks and days of life is imperative to cope with the changes as they occur.
These changes can vary from person to person. Although patients progress through the end-of-life process differently, there is usually a recognizable pattern of decline that occurs. To provide the best possible care and prepare both the dying patient and their family members, it is important for the nurse and caregiver to be able to distinguish the phases of the end-of-life process: transitioning, actively dying, and final moments.
Transitioning
The transitioning phase, otherwise identified as the pre-active phase, usually signals that a person is approaching the last two-to-three weeks of their life. During this time, caregivers might start to notice obvious changes, an increase in sleeping, for example. A transitioning person can sleep upwards of twenty hours per day. This significant increase is part of an overarching decrease in the patient engaging with the world and day-to-day life.
Beyond sleeping, examples of this disengagement include interacting less with friends and family, less desire to do one’s usual activities, and a lack of interest in things that were once pleasurable. Additional signs of a patient transitioning include increased weakness and decreased mobility.
These changes typically include a decline in function, becoming non-ambulatory, chairbound, and ultimately, bedbound. Patients may begin to fall during this time. Progressively, the patient will become more dependent on their caregivers to assist them with activities of daily living (ADL), which include bathing, eating, transferring, toileting, and continence. They will likely become bedbound.
Another indicator that someone may be transitioning is a change in nutrition and intake. Eating and drinking less is an expected part of decline during this time. Many patients will report a lack of appetite, taste changes, and an overall lack of interest in food and liquids. Changes in swallowing may further complicate a person’s ability to eat and drink.
It is not uncommon to downgrade a person’s diet during the transition phase. This might include going from a regular diet, down to soft, and finally, to pureed. Liquids are usually given in small amounts and with an added thickener. These changes are necessary to prevent choking and aspiration. Fluid overload is a risk at this point and can detract from one’s comfort, cause swelling, or crackles in the lungs.
“Approximately 43% of all palliative patients are affected by terminal agitation, which can manifest as restlessness, sweating and patients’ statements as verbal or facial expressions and defensive reactions” (5).
Increased agitation, anxiety, and restlessness may also arise during the transitioning phase. Terminal agitation and terminal restlessness are both unique to the last week or so of someone’s life and are often caused by physiological changes that occur during the end-of-life process but can also be a result of medication or emotional changes. Even if the patient had been calm previously, it is important to note that these symptoms may still occur.
Signs of terminal agitation include an inability to remain still, picking at items in the surrounding environment, and increased confusion. Fortunately, there are medications that can be given at the end of life to promote comfort and stop these symptoms when they arise. Lastly, it is not uncommon for the transitioning patient to have visions of and talk to deceased friends and family – both are normal and could sometimes be interpreted as a welcoming sign from loved ones.

Active Dying
Following the transition phase, most patients will then enter the final phase of the end-of-life process, the active dying period. This precedes imminent death. It can be hard to determine precisely when this stage begins. This phase usually lasts only two to three days and showcases significant signs of patient decline that differ from the previous phase, including a decrease in alertness and responsiveness.
For example, a patient may go from a semi-comatose state to comatose or obtunded and minimal reaction should be expected (1). Their eyes may be open or shut, and there is little movement in all extremities. This period can be described as a deep sleep.
Caregivers often describe it as a time of waiting. Cognitive changes, in combination with the previous changes in swallowing, make the intake of food, liquids, and medications unsafe. The patient is at high risk for aspiration. Mouth swabs can be used to hydrate the oral cavity and to do mouth care.
Medications that are liquid or can dissolve under the tongue are safe and can be used to manage symptoms at the end of life. Hospice patients are provided a comfort kit of medications to use should symptoms arise.
Additionally, changes in vitals are expected during this phase, and they typically do not cause the patient any discomfort. For example, temperature fluctuation is common at the end of life. It is not abnormal to have an elevated temperature during the active dying phase. This can be remedied with cooling measures such as a cool towel on the forehead or a fan to cool down the room. The skin may feel clammy as well.
Following, changes in blood pressure and heart rate may also occur. Blood pressure begins to trend lower during the pre-active phase and can become very low during the last few days of life. The heart rate will usually trend upward and can be well over 100 beats per minute, however, this is just something for the hospice nurse to note and is not usually treated.
Symptom management at the end of life can be difficult. Failure to adequately control symptoms can have a negative impact on one’s quality of life. These symptoms may include pain, respiratory distress, GI issues, and mobility changes (2). Pain while dying is one of the most common areas of concern for someone who is actively dying, and of course, no one wants to see their loved one in pain during their final days of life. The body becomes very sensitive to the slightest movement or touch, which can present challenges for caregivers when considering that the patient still needs to be cleaned, changed, and repositioned.
When the patient is no longer verbalizing their comfort, verbal pain cues must be assessed. These include grimacing, a furrowed brow, frowning, and possibly moaning. In some cases, repositioning can be an effective pain-relieving measure. Thankfully, pain can be treated up until death occurs.
Opioids are commonly used in end-of-life care, due to their ability to effectively manage pain without hastening death. Morphine is an example of a commonly used opioid (4). Nonpharmacological measures can also be used to relieve pain. This may include things like repositioning and soothing music.
Decreased urination is also common during the active dying phase. This is completely normal and expected. Caregivers may find that they do not need to change diapers as often. Urine may also appear darker in color, appearing a deep amber color due to more concentrated urine.
Excessive secretions can lead to something commonly known as the “death rattle.” This term is almost synonymous with the last days of life. It can be described as a moist sound that is audible when someone breathes and is a good indicator that death is near. The secretions collect in the throat due to a lack of coughing and the inability to clear them out (8).
Turning the patient on his or her side may help the secretions drain, and there are medications that can be administered to help dry them out. It is important to note that not everyone will experience this, and by the time it occurs, there is a disconnect within the patient, and he or she is not likely to experience any discomfort.
Maintaining skin integrity and preventing pressure injuries is also an important consideration during this time. With all the other previously mentioned changes occurring, it can be hard to provide the attention that the skin requires. Like other organs, the skin begins to fail in an actively dying patient (9).
This does not necessarily mean that pressure injuries and skin breakdown are inevitable. It is important to consider goals of care during this time. An aggressive approach to preventing skin breakdown might not be what the patient wants or necessarily needs. Measures for pressure injury prevention might include repositioning, use of pillows for elevation, hygiene, and moisture management.

Final Moments
It can be hard to imagine the final moments of someone’s life. This is especially true for caregivers and families who have witnessed steady decline throughout both stages of dying. There are likely to be signs that death is possible at any moment. A patient can be expected to be comatose with little to no response when death is imminent. The obtunded patient appears to be in a deep sleep. They are no longer verbally or physically responsive to voice or tactile stimulation.
In addition to changes in vitals described previously, changes in respiration usually occur. This is typically the most obvious change. Patterns can vary from shallow and fast to deep and slow. Periods of apnea are also normal. Cheyne-stokes breathing may also be present (3).
Skin changes are also expected; pallor, cyanosis, and mottling are signs that death is near. The body may begin to feel cool, especially in the hands and feet. Comfort medications can still safely be used up until death occurs. As mentioned before, foods and liquids should not be given at this point. Caregivers should continue to talk to the patient, as their hearing will remain until the end.
Hospice
Most people wish to die peacefully at home. Unfortunately, for many, this is not the case. Over 30% of people die in a hospital setting (6). Hospice is a form of palliative care and involves caring for the terminally ill as they begin the end-of-life process. A terminally ill patient has a life expectancy of 6 months or less. This is a comfort focused approach to care. The natural process of dying is accepted and allowed to proceed.
No life prolonging treatments or procedures are elected. Choosing a hospice allows both patients and their caregivers to achieve their end-of-life care goals. Hospice care includes an interdisciplinary team composed of nurses, physicians, aides, chaplains, and social workers. It includes symptom management, and emotional and spiritual support. There is also a bereavement team that is available after death. Medicare part A covers hospice services nearly completely.
Hospice care can be a short or long journey, with many ups and downs. For some, the prognosis might be obvious, but for others, it might be filled with many questions and much uncertainty. The benefits of hospice care are proven and can lead to a peaceful death. “The main care focus for patients is symptom management, which improves the quality of the remainder of their life.
Palliative care involves not only the patient but also their family members. Other measures are also taken so that the patients can live life comfortably and maintain dignity” (7). Both caregivers and patients seek to understand what end of life care entails and how to maintain comfort at end of life. Hospice clinicians should spend time providing education on this process to all of those involved.
Spiritual Considerations at End of Life
Taking care of the dying should be looked at from a holistic point of view. Addressing the physical needs of someone who is dying while ignoring any spiritual needs would be doing a disservice. Spirituality is considered the meaning of life. It may include religion, beliefs, or family traditions. It can mean different things to different people.
During end-of-life care, it has been shown to be disrupted in patients. Spiritual needs tend to be greater at the end of life. It is also frequently overlooked by healthcare professionals (10). Palliative care workers can help address spiritual needs in their patients by showing compassion, humility, and openness.
Dying patients may be conflicted spiritually due to things like guilt and unresolved issues. When spirituality is addressed appropriately, patients can more positively cope with illness. Caregivers of the dying should be aware of the relationship between a terminal prognosis and unmet spiritual needs.
Self Quiz
Ask yourself...
- Have you been present when someone died? How did it make you feel to witness this?
- What are signs that death is imminent?
- How do respirations change just prior to death?
- What education would you provide to a caregiver during this time?
Conclusion
Hopefully, this has been an informative piece and a guide on what to expect during end-of-life care. No two people experience death and dying in the same manner, and it can be challenging both physically and emotionally during the end of life. Proper symptom management during this time is crucial in ensuring that one dies comfortably. One should also consider any unmet spiritual needs and how, if unaddressed, could lead to poor patient outcomes.
Palliative care at the end of life can be a great help for caregivers. Hospice can be a great resource in managing symptoms and providing support up until death and beyond. Most people do not have experience in caring for a dying person and need education and assistance throughout the journey. Not everyone who is dying will experience all the symptoms mentioned in this course, and it is important to note that everyone experiences the end-of-life process in their own way and at their own pace.
Tirzepatide for Type 2 Diabetes and Weight Management
Introduction
The emergence of the drug tirzepatide is becoming more popular and widespread and is being utilized among those with diabetes and also those who desire to lose weight. It is one of the newest diabetic drugs given by injection that also triggers dramatic weight loss in those who use the injections.
The U.S. Food and Drug Administration (FDA) approved tirzepatide in 2022 for individuals with diabetes, particularly Type 2 Diabetes. The FDA officials have not approved tirzepatide yet for weight loss, but they are currently tracking the medication and may have a recommendation for its approval by the end of this year. Clinical trials have shown that individuals with an elevated body mass index (BMI) and who did not have diabetes lost a considerable amount of weight when they received tirzepatide (1).
Advanced Practice Registered Nurses (APRNs) need to understand how to safely prescribe tirzepatide and the reasoning as to why it causes weight loss for specific individuals.
Drug Classification
Tirzepatide is part of a class of medications called glucose-dependent insulin tropic polypeptide (GIP) receptor and glucagon-like peptide-1 (GLP-1) receptor agonists. It comprises a 39 amino acid linear synthetic peptide conjugate to selective receptor agonists in preclinical and clinical trials.
Tirzepatide is used for treating Type II diabetes in adults as an adjunct to diet and exercise. It is also used for weight loss in some individuals and has gained increased attention as a new therapeutic agent for glycemic and weight control.
Social media has had a significant influence and increased the desire to use tirzepatide, and while individual results vary, the weight loss in adults ranged from 12 – 25 pounds.
Online pharmacies, diet clinics, and medical spas are implementing thousands of ads on social media to capitalize on a surge of interest in the drug.
Self Quiz
Ask yourself...
- Why has there seemed to be an increase in patients requesting this medication? What other medicines intended for type 2 diabetes are also being used for weight loss management?
- What are the ethical considerations regarding marketing this drug for weight loss when its primary use is for type 2 diabetes? Could this impact supply and costs?
Indications of Usage
The use of tirzepatide is being used for both Type II diabetes and weight control in certain patients. It has been a game changer for people living with Type II diabetes. The drug’s primary use is as an adjunct to diet and exercise to improve glycemic control in adults with diabetes.
The drug has also proven beneficial for weight loss in patients experiencing obesity, and those who are taking the highest dosage have shared a body weight reduction of 15.7% (2). Tirzepatide is an injectable prescription medication used together with diet and exercise, and it is not yet known if it can be used safely with patients who have had pancreatitis.
It is important to remember that it is not to be used for patients with Type I diabetes, but it is safe for Type II diabetic patients. Also, the safety of tirzepatide has yet to be discovered for children and those under 18; therefore, the medication should not be used for this age group.
In studies conducted with or without diabetic medicines, 75% – 90% of patients taking tirzepatide reached an overall A1C of less than 7% with an average starting A1C of 7.9 – 8.6% across the following dosages – 5mg, 10mg, and 15mg. The study results were measured at weeks 40 and 52 (3).
Self Quiz
Ask yourself...
- What dietary and activity recommendations can you provide to patients using tirzepatide for weight loss?
- Is this drug intended for those who want to lose 5-10 pounds?
Use of Tirzepatide with Diabetic Patients
Tirzepatide can be used for patients with Type II diabetes in combination with a diabetic-friendly diet and exercise. The drug works by lowering the patient’s overall blood sugar and also improves the A1C results of patients over some time. The injection has been approved by the FDA to treat Type II diabetes and is administered once weekly (4).
It is considered the first in a new class of medications – a dual glucose-dependent insulin tropic polypeptide (GIP) and glucagon-like-peptide-1 (GLP-1) receptor antagonist. The mechanism of how it works mimics two gut hormones (GIP and GLP-1). These hormones are essential in how patients digest food and regulate blood glucose after meals. The hormones also play a role in making individuals feel fuller and curb specific food cravings.
The provider can prescribe tirzepatide before attempting other diabetic medications if a patient has a BMI of 30 or greater or 27 or greater with weight-related conditions and if the drug is combined with a personalized weight loss plan that addresses physical activity, nutrition, and lifestyle changes.
However, due to the cost and some insurance companies not covering the injection unless the patient has both diabetes and obesity, the provider must carefully consider prescribing this medication.
Case Study
The patient states this ‘miracle drug’ is worth paying for out of pocket!
Jeff Capron, a 53-year-old Boonville, New York, web developer, started taking tirzepatide in December 2022. His friend had reported good results with the medication, so Jeff looked into the research studies behind it and then spoke with his primary physician.
The physician said, “Yeah, let’s give it a shot,” even though he did not have much experience with it. The physician did not have an opinion one way or the other than looking at the data set and seeing no reason why they could not try it.
Jeff’s hemoglobin A1C went from 10.1% to 6% in 3 months, which was very promising. “I never had that kind of experience with any medication for diabetes.” There is a range in how much A1C reduction people experience with tirzepatide, but many people taking it can get their A1C under 7% — an ideal goal for people with Type 2 diabetes.
Jeff experienced constipation and a little trouble sleeping early, but both issues disappeared quickly. He says, “I wake up in the morning, and my fasting blood sugars are normal.”
The medication took effect, he says, within 12 hours. He compared the feeling to having a gastric bypass.
“You cannot overeat food. As soon as you overeat, you almost feel ill.” While it generally takes a few months to notice effects like A1C reduction and significant weight loss, side effects such as lower appetite may be felt immediately.
Weight loss was not his primary goal, but he lost about 35 pounds on the medication in the first five months. He also lost his sweet tooth. “I can maybe count three sweet things I have eaten since December.”
Jeff found that his appetite slowly recovered days after taking tirzepatide. “You take the shot every Sunday, and by Saturday, you start to get a lot of appetite,” he says. “It does not seem to affect your weight. If I eat a little bit more on Saturday night, on Sunday, the scale will not move one way or the other.”
Jeff is allergic to hornets, so he already carries an auto-injector. He was not worried about using another drug delivered through a needle. “It’s just a push button,” he says. It also helped that his wife is a nurse. “So, I had her with me the first time to ensure I was doing it right. I didn’t even feel it.”
When Jeff was first prescribed tirzepatide, his insurance covered it. The company has since removed that benefit. He has filed an appeal but pays about $1,000 monthly out of pocket for his weekly injections. He plans to keep paying as long as necessary.
He considers the financial burden well worth it. “I have never had a medication that worked as well before for chronic conditions,” Jeff says. “I’ve been blown away by it. For me, it’s a miracle drug. It got rid of my diabetes” (4).

Use of Tirzepatide for Weight Loss Management
As mentioned, this medication is indicated for patients with a BMI of >30 or a BMI of >27 with qualifying comorbidities. Obesity can become a chronic lifetime disease, and for conditions such as these, the patient needs to implement therapy for the lifetime of the disease.
In a study conducted for tirzepatide, there was a dramatic increase in effectiveness compared to traditional nonsurgical interventions such as diet, exercise, and lifestyle changes. However, it has been noted that taking tirzepatide on an ongoing basis is recommended and necessary to maintain any weight loss achieved from the medication.
If a patient stops taking the drug, likely, it will no longer work (5).
Public health officials have expressed concerns about using the drug long-term. Still, data is currently lacking regarding long-term effectiveness, treatment duration, and maintaining weight reduction once the therapy is discontinued.
A recent trial consisted of 783 participants with a BMI greater than 30, and these participants agreed to take either a 10mg or 15mg dose of tirzepatide over 36 weeks. The injection is given once weekly, so this would equal a total of 36 injections.
By the end of 36 weeks, participants lost more than 21% of their body weight. After 36 weeks, participants continued on tirzepatide or received placebo treatment for the following year. The patients needed to be made aware of which treatment they were receiving.
Those still taking tirzepatide injections weekly after 88 weeks lost an additional 7% of their body weight, and those taking the placebo regained 15% at the end of 88 weeks (5).

Common Side Effects and Contraindications
Side Effects
Patients vary immensely with different experiences and side effects related to tirzepatide; however, the following are the most common side effects experienced by those taking the medication:
- Nausea
- Decreased appetite
- Vomiting
- Diarrhea
- Indigestion
- Constipation
- Stomach Pain
Tirzepatide usually does not cause fatigue, leaving one feeling weak, tired, and low energy. However, fatigue can be a common side effect of Type II diabetes.
It is important to note that most individuals who experience nausea, vomiting, and diarrhea episodes do so while the dosage increases, and typically, the symptoms decrease over time. G.I. effects were more prominent in those taking tirzepatide than those taking the placebo. The individuals not in the placebo group were more likely to stop treatment due to the unpleasant side effects (3).
Self Quiz

- Does tirzepatide cause fatigue in patients who use it?
Contraindications
Tirzepatide may cause thyroid tumors, including thyroid cancer, and it is essential to watch for possible symptoms, such as swelling or a lump in the neck, hoarseness, shortness of breath, or trouble swallowing.
Tirzepatide should also not be prescribed to any patient with Type 1 Diabetes.
One of the main ways that tirzepatide works is by stimulating the release of insulin from the pancreas, and due to this fact, there have not been many studies and clinical trials that include those with Type I diabetes.
However, this is not to say that prescribers have never ordered tirzepatide for those with Type I diabetes. Still, it is essential to note that if prescribed, it would be in addition to traditional insulin therapy.
- Personal or family history of a type of thyroid cancer known as medullary thyroid carcinoma (MTC).
- Any history of Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

Safe Prescribing Practices, Guidelines, and Considerations for Providers
Safe Prescribing Practices
As with all prescribed medications, safe standards of care must be implemented and followed to ensure patient safety is maintained. The same applies to providers considering prescribing tirzepatide, and specific criteria must be met beforehand. The following information discusses guidelines involving exclusion and inclusion criteria for providers to prescribe tirzepatide (6) accurately.
Guidelines
Exclusion Criteria – If present, the following indicates that the patient should not receive tirzepatide:
- Diagnosis of Type I diabetes
- Personal or family history of medullary thyroid carcinoma or with Multiple Endocrine Neoplasia syndrome type 2
- Severe gastrointestinal dysmotility
- History of pancreatitis
- Pregnancy
- Proliferative Diabetic Retinopathy (PDR), severe Nonproliferative Diabetic Retinopathy (NDR), clinically significant myalgic encephalomyelitis (M.E.), or diabetic macular edema (DME) unless the risks/benefits have been discussed with the patient and are documented in the patient's health record along with monitoring plans and follow-up with an eye specialist who is informed at the time of initiation.
Inclusion Criteria – All of the following must be met for tirzepatide to be prescribed:
- Diagnosis of Type II diabetes
- A BMI of 25 or greater
- Inadequate glycemic control on at least 1mg of semaglutide injection plus two or more glucose-lowering drugs
- Change needed to achieve goal A1C is less than 1%.
- Goal A1C should be based on those recommended in the Diabetic Guidelines.
- Adherence to current diabetic medications as evidenced by a review of the prescription refill history during the six months.
Additional Inclusion Criteria – All of the following must be met for tirzepatide to be prescribed:
- Patients with atherosclerotic cardiovascular disease or chronic kidney disease
- Patients of childbearing potential who are using oral contraceptives
Inclusion Criteria for Weight Loss
- BMI of >30 or >27 with patient weight conditions.

- Would a patient with a BMI of 23 with no comorbidities qualify to use tirzepatide to lose 5-10% of their body weight? Why not?
- What impact can tirzepatide have on a person with a healthy weight and BMI of <25?
Considerations for Providers
There are specific considerations that prescribers must be aware of when contemplating if a patient should receive the medication tirzepatide. The following is imperative and must be considered each time the medication is prescribed to a patient:
- Clinical Indications – indicated for treating adults with insufficiently controlled diabetes mellitus as an add-on therapy to diet and exercise; as monotherapy when metformin is considered inappropriate due to contraindications or intolerance; and other medicinal products for treating Type II diabetes.
- Monitoring of medication – routine monitoring of serum calcitonin or thyroid ultrasound is of uncertain value but is recommended for early detection of Medullary Thyroid Cancer (MTC).
- Cost – the average price for tirzepatide ranges from $1,071-$1,351 without any coupons or insurance. Savings Card – manufacturer provided; patients can pay as little as $25 monthly for up to 12 injections. Savings Card – manufacturer provided; patients can pay as little as $25 monthly for up to 12 injections.
- Benefits and Risks – One must evaluate the effectiveness of diabetes and the weight loss experienced. Some of the risks must be evaluated, such as increased cost of medication, unpleasant gastrointestinal side effects, poor insurance coverage, and drug shortages. The FDA has warned that the medicine can cause thyroid C-cell tumors in rats, and it is not sure whether tirzepatide causes similar tumors.
How long does it take for tirzepatide to begin working?
Tirzepatide will start to lower one's blood sugar levels immediately, but it can take 8 to 12 weeks to reach one's target A1C goal.
Compared to other diabetic treatments, studies have shown that it can take eight weeks to reach an A1C target of less than or equal to 7% and 12 weeks to get an A1C of less than or equal to 6.5%. Significant weight loss can occur as early as 28 weeks.
Safe Administration
It is essential to follow the correct steps for safe administration of tirzepatide as listed below:
- The recommended starting dosage is 2.5mg, injected subcutaneously once weekly. The 2.5mg dosage is for treatment initiation and not for glycemic control.
- After four weeks, increase the dosage to 5mg, injected subcutaneously once weekly.
- If additional glycemic control is needed, increase the dosage in 2.5mg increments after at least four weeks on the current dose.
- The maximum dosage is 15mg, injected subcutaneously once weekly.
- If a dose is missed, instruct patients to administer it as soon as possible, within four days (96 hours) after the missed dose. If more than four days have passed, skip the missed dose, and administer the next dose on the regularly scheduled day. In each case, patients can then resume their regular once-weekly dosing schedule.
- The day of weekly Administration can be changed, if necessary, as long as the time between the two doses is at least three days (72 hours).
- Before initiation, train patients and caregivers on proper injection techniques.
- Instruct patients using the single-dose vial to use a syringe appropriate for dose administration (e.g., a 1ml syringe capable of measuring a 0.5 mL dose).
- Administer the medication once weekly, any time of day.
- Inject the medication subcutaneously in the abdomen, thigh, or upper arm.
- Rotate injection sites with each dose.
- Inspect the medication visually before use. It should appear clear and colorless to slightly yellow. Do not use the medicine if particulate matter or discoloration is seen.
- When using the medication with insulin, administer it as separate injections and never mix. It is acceptable to inject tirzepatide and insulin in the same body region, but the injections should not be adjacent.
Does the tirzepatide injection hurt when administered?
Pain from the injection site has not been reported as a common side effect, but it may occur.
Due to the injection being given subcutaneously, slight pain or discomfort can occur.

Alternatives to Tirzepatide for Weight Loss Management
In some instances, patients need to be aware of alternatives to tirzepatide in case they cannot take the actual injection for whatever reason. In cases such as these, there are alternative supplements that can be purchased over the counter, and they include the following (7):
- PhenQ – top OTC choice – comprehensive weight loss solution that targets specific body regions, facilitates prompt fat loss, and expedites the weight loss journey.
- PhenGold – the most potent OTC weight loss alternative – one of the top weight loss supplements that boost metabolism, making one less hungry, less tired, and an overall improved feeling.
- Capsiplex BURN – the best choice for men – helps to burn fat faster and keep blood sugar levels in check. It helps to keep one's muscles, curbs hunger, gives one more energy, and torches stubborn fats.
- Trimtone – the best choice for women – helps women to lose weight, eat less, increase metabolism, burn extra calories, and boost energy.
- Prime Shred – best fat burner for men – boosts metabolism, keeps muscles intact, increases energy, and helps maintain focus.
The advanced practicing nurse or prescriber needs to inform patients about alternative options such as these in an effort for individuals to understand that other choices are available and can be used. Many individuals need to be more knowledgeable about alternatives besides tirzepatide due to the extra hype from social media sources that promote advertisements related to tirzepatide only but do not mention the other options.
Why does social media influence and encourage patients to take tirzepatide?
Social media trends can be helpful but can also become harmful by setting unrealistic expectations and promoting a diet culture mentality. They can create an unhealthy obsession with "clean" eating, especially in the younger populations.
Due to this, many individuals take the medication despite any occurrence or history of Type II diabetes, and the drug can ultimately become misused.
It has been noted that there is an influx of patients requesting this medication for weight loss instead of the intended purpose, which is to help control Type II diabetes.
Tirzepatide represents one of the most recent non-medical treatments aimed at managing the symptoms of Type II diabetes. While it is not indicated for weight management, diabetic patients who receive it frequently report a significant reduction in body weight.
Empirical evidence suggests the efficacy of tirzepatide in weight management, and certain physicians currently endorse the Administration of the medication as a therapeutic and effective means to overcome obesity.
What are some severe side effects of tirzepatide that can impact patient safety?
The Administration of tirzepatide can benefit many individuals, but some severe side effects must be mentioned.
These include thyroid tumors, thyroid cancer, pancreatitis, hypoglycemia, serious allergic reactions, kidney issues, severe stomach problems, vision changes, and gallbladder issues. All these side effects must be taken seriously and reported, as they can lead to life-threatening

Conclusion
Medications like tirzepatide are game changers for those patients with type 2 diabetes that have failed other medications. Unfortunately, several companies seek to profit from its weight-loss benefits through aggressive marketing campaigns that limit the available supply and increase the costs for those who need it. As healthcare providers, we need to use sound clinical judgment and follow the exclusion/inclusion criteria and other guidelines before prescribing this medication, so we do not unintentionally cause harm while looking to appease our patients who request this.
Semaglutide and Type 2 Diabetes
Introduction
In 2017, the FDA approved the semaglutide injectable (Ozempic) for treating type 2 diabetes. The drug has experienced widespread acceptance due to its positive effects on weight loss and lowering of chronic health risks. The drug has risen in popularity over the past few years, as many well-known actors/actresses/songwriters, and more came forward, publicly sharing their weight loss journey.
This rise in popularity has also resulted in significant shortages of this medication, negatively impacting the lives of the diabetic community, local pharmacies, and healthcare providers. The goal of this continuing education course is to educate and empower the healthcare provider in all aspects of this drug regimen: clinical indications, patient education, cost options, and benefit/risk analysis.
Diabetes Overview
Diabetes is a chronic medical condition. Despite advances in diet, medications, and monitoring devices, diabetes diagnoses continue to grow at staggering rates. The Institute for Health Metrics and Evaluation (IHME) reports that over 529 million people worldwide are currently living with diabetes, and that number is expected to grow to 1.3 billion in only 30 years. While the risk factors for diabetes are vast in number (poor diet, inadequate activity, obesity, sedentary lifestyles, daily stressors, and more), the sad reality is that this chronic medical condition will most likely linger on for generations to come despite our efforts to contain this health epidemic (1).
According to the latest research on diabetes, there are over 37 million people in the United States alone with diabetes as of 2022. Statistically, approximately 28 million of them have a confirmed diagnosis, while another estimated 8 million are experiencing symptoms, without an official diagnosis. Diabetes currently ranks as the 7th leading cause of death in the United States (2).

Types of Diabetes
In basic terms, diabetes is an impairment in one’s ability to either adequately produce or utilize insulin, which results in elevated levels of circulating glucose. Chronically elevated glucose levels affect blood vessels at every level, causing chronic inflammation and raising the risk of heart disease, stroke, blindness, and atraumatic amputations.
There are three main types of diabetes:
Type 1 diabetes is thought to be an autoimmune disease. Approximately 5-10 percent of people with diabetes are diagnosed with type 1 diabetes. The diagnosis usually occurs in early childhood, and results in a lifetime use of insulin to regulate blood glucose levels.
Type 2 diabetes is thought to be related to dietary and lifestyle choices. It accounts for nearly 90-95 percent of diabetes diagnoses. Usually occurring later in life (adult-elderly population), it is believed to be related to factors such as diet, activity, weight gain, and related factors. Type 2 diabetes is usually controlled by diet and exercise, in addition to oral medications, although injectable insulin may be included in the treatment plan.
Gestational diabetes refers to elevated glucose levels occurring during pregnancy for patients who are not diabetic at the onset of pregnancy. This version of diabetes usually resolves itself post-partum, although a woman may develop type 2 diabetes later in life, unrelated to pregnancy.
Type 2 diabetes in children: no longer a “later in life diagnosis”
Children are now being diagnosed with type 2 diabetes at an alarming rate. Despite widespread education and an increased awareness of diabetes, our up-and-coming generation is unhealthier than ever. Many families lack access to healthy food for their families, due to both general socioeconomic challenges and an increased rate of food insecurity. (19)
The CDC recommends care providers have resources for diabetic patients and their families, such as food and nutrition programs, budget-friendly diabetes meal plans, how to save money on diabetes care, and coping strategies for diabetes. (19)

Diabetes Signs and Symptoms, Diagnostic Testing
There are various ways to test for diabetes. The fasting blood sugar (FBS)/ fasting glucose level is a simple way to test for diabetes.
The normal fasting glucose level is below 100mg/dl. The fasting glucose result of 100-125mg/dl indicates prediabetes and results above 126mg/dl indicate diabetes.
The hemoglobin A1C blood test is another test used to confirm the diagnosis of diabetes. The patient does not need to be fasting for this test; thus, it is easier to order this test regardless of the time of day. This blood test reflects the average glucose level over the period of 2-3 months.
The normal A1C level is below 5.7%. Test results between 5.7%- 6.4% indicate prediabetes. Test results above 6.5% indicate diabetes.
A random glucose reading above 200mg/dl, done at any time of day, indicates diabetes.
The diagnosis of diabetes is by blood tests, and for improved accuracy, should be based on two separate readings, done (at least) a day apart. In the case of fasting and random blood tests, dietary intake (large amounts of carbohydrates in a single meal) may adversely affect test results. This is not the case when using A1C testing for a confirmation diagnosis, as the results are the average of a 2–3-month span.
Target blood levels for a person with diabetes (3).
Target blood glucose levels for people with diabetes are as follows:
- Fasting glucose 80-130mg/dl.
- Postprandial blood glucose level- less than 180mg/dl
- A1C level 7-8%.
These target ranges are general guidelines. Patient-specific ranges will be dependent on a variety of factors, including preexisting comorbidities, overall health status, age, and activity levels.
The hallmark signs/symptoms of diabetes
- Polyuria- increased urination
- Polydipsia- increased thirst
- Polyphagia-increased hunger/appetite
The truth is, as healthcare providers, you will have patients who have no hallmark signs and symptoms of diabetes; the diagnosis will be found during annual preventive examinations often unrelated to any chronic disease. For this reason, many insurance companies now cover numerous preventive screenings, including diabetes screenings, as part of their wellness and prevention initiatives. These tests are often approved based on a patient's age, or preexisting conditions, rather than outright signs and symptoms.

Lifestyle Interventions and the Diabetes Prevention Program
The initial diagnosis of diabetes can be managed in a variety of ways, depending on the severity of the illness at the time of diagnosis. Lifestyle interventions (behavior modification education) are of utmost importance in the care and management of people with diabetes. Research over the past few decades has consistently shown that such interventions have immense positive effects on the successful long-term management of diabetes.
The official Diabetes Prevention Program was created in 2010 (4) and confirmed the effects of lifestyle interventions in the management of diabetes: Lifestyle interventions decreased the incidence of type 2 diabetes by 58% compared with 31% in the metformin-treated group. Thus, these findings now serve as the blueprint, if you will, for all-inclusive, patient-specific disease management guidelines. These lifestyle interventions will be discussed in detail later in the program.

Semaglutide
Semaglutide is an injectable drug used in the treatment of type 2 diabetes. It was approved by the FDA in May of 2017.
It is a once-a-week injectable and belongs to the drug class known as glucagon-like peptide-1 receptor agonists (GLP-1RAs) (5). It has been referred to as a “miracle weight loss drug” among those who are living with obesity, despite frequent side effects, unusually high out-of-pocket costs, drug shortages, and weight regain when attempting to stop using the medication.
GLP-1 receptor agonist: Hormone Review
GLP-1 RAs are a class of medications used to treat Type 2 diabetes, and in some cases, obesity treatment. They are also known as GLP-1 receptor agonists, incretin mimetics, and GLP-1 analogs.
Ghrelin and Leptin (6)
Ghrelin and Leptin are two hormones that greatly influence appetite and the sensation of fullness. Often referred to as the “hunger hormone.” Ghrelin is responsible for many functions, including playing a key role in metabolism through glucose and insulin regulation.
Ghrelin, produced in your stomach, signals your brain when you are hungry, and results in increased food intake.
Leptin, conversely, is produced in your fat cells, and signals to the brain when you have eaten enough (by a decrease in appetite).
Glucagon-like peptide-1 receptors
Known as GLP1 receptors, Glucagon-like peptide-1 receptor proteins are located in the beta cells of the pancreas as well as in the neurons in the brain. GLP-1 receptors are involved in the regulation of blood glucose levels and affect the secretion of insulin. These cells encourage the release of insulin from the pancreas, increase the volume of beta cells, and reduce the release of glucagon. In doing so, they increase the feeling of fullness during and between meals, suppressing the appetite and slowing gastric emptying.
Self Quiz
Ask yourself...
- What are some problems patients might face if they choose to take semaglutide?
- How do Ghrelin and Leptin relate to a patient's appetite?
What is meant by receptor agonist and antagonist?
The term agonist refers to any substance that mimics the actions of a hormone in producing a specific response: a receptor antagonist blocks a response from occurring.
Opioids are examples of receptor agonists in that they produce responses such as analgesia.
Naloxone/Narcan is an example of a receptor antagonist, in that it binds to a receptor site and decreases/blocks a response from occurring.
Semaglutide mechanism of action (7)
GLP-1 agonists work in several ways to positively affect glucose levels. Their mechanism of action includes the following:
- Increasing (stimulating) insulin secretion by the pancreatic beta cells.
- Decreasing the production of glucagon, a hormone that raises blood glucose levels
- Decreasing (slowing) gastric emptying
- Decreasing appetite (and thereby reducing food intake) by creating a sensation of stomach fullness
Through these mechanisms of action, semaglutide results in a lowering of serum glucose/A1C levels, which lowers the risk of cardiovascular events. Studies have also shown that semaglutide resulted in weight loss (approximately 8-14 pounds on average {dose dependent results}.

Side Effects of Semaglutide
Common side effects of semaglutide (8)
Common side effects may include any of the following:
- Nausea and vomiting
- Headache
- Diarrhea and stomach pain
- Upset stomach, indigestion, constipation, flatulence
These side effects usually subside within a few weeks, as the patient becomes acclimated to the medication.
Serious side effects of semaglutide
- Hypoglycemia- enhanced/worsened when used in combination with other diabetes medication. Symptoms may include drowsiness, confusion, weakness, irritability, and headache.
- Symptoms may include abdominal pain and distension, nausea and vomiting, fever, and back pain.
- Diabetic retinopathy. Symptoms may include blurred vision, vision loss, and diminished night vision.
- Kidney damage/injury/failure. Symptoms may include fatigue, nausea, diminished urine output, confusion, and edema of extremities.
- Gallbladder disease. Symptoms may include gallstones, abdominal pain, nausea and vomiting, and poor appetite.
Black Box Warning (9)
Semaglutide has a Black Box Warning for thyroid cancer. This is the most serious warning from the Food and Drug Administration (FDA) and is intended to alert consumers to the potential risks of a medication. This black box warning was issued when research found that the drug increased the risk of thyroid tumors in animals.
It is not known if semaglutide actually causes tumors in humans.
Contraindications
- Semaglutide is contraindicated in people with a personal or family history of MTC (medullary thyroid cancer) or in patients with multiple endocrine neoplasia syndrome type 2.
- Known hypersensitivity to semaglutide or any of the product components
Cautions
As noted under “serious side effects”, there have been reports of new illnesses or worsening of existing health conditions occurring “post-marketing”. Thus, healthcare providers are strongly encouraged to continue ongoing surveillance of any patients on semaglutide therapy. In addition, there is insufficient data available regarding the use of semaglutide by pregnant women. Women are therefore highly encouraged to stop any treatment with semaglutide for at least 2 months prior to a planned pregnancy.

Dosing
Semaglutide is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus (T2DM). It is looked upon favorably to reduce the risk of cardiovascular events in adults with T2DM and a preexisting history of cardiovascular disease. This drug is FDA-approved for use in people with diabetes, with a BMI of 27% or higher (a BMI of 25-29.9% is considered overweight).
Semaglutide (Ozempic) is available as an injectable prescription medication. Doses include 0.5mg, 1mg, or 2 mg, once weekly.
The injection should be administered subcutaneously to the abdomen, thigh, or upper arm. Injection sites should be rotated, and given as a single injection.
Start at 0.25 mg once weekly. After 4 weeks, increase the dose to 0.5 mg once weekly.
- If additional glycemic control is needed, increase the dose to 1 mg once weekly after at least 4 weeks on the 0.5 mg dose.
- If additional glycemic control is needed, increase the dose to 2 mg once weekly after at least 4 weeks on the 1 mg dose
Administer once weekly at any time of day, with or without meals. The maximum dose recommendation is 2mg/weekly once weekly.
Note: The initial 0.25-mg dose is intended for treatment initiation and is not effective for glycemic control
Missing Dose Guidelines
- If the missed dose is ≤5 days: Administer dose as soon as possible
- If missed dose >5 days: Skip the missed dose and administer the next dose on the regularly scheduled day; patients can then resume their regular once-weekly dosing schedule
Administration Day Guidelines (10).
The administration day each week can be changed, if necessary, as long as the time between 2 doses is at least 2 days (>48 hours)
Dose Availability (packaging)
- 2mg/1.5mL (1.34mg/mL); delivers doses of 0.25mg or 0.5mg per injection or four to eight doses per injection pen
- 4mg/3mL (1.34mg/mL); delivers 1mg per injection or 4 doses per injection pen
- 8mg/3mL (2.68 mg/mL); delivers 2mg per injection or 4 doses per injection pen
Treatment Goals- Effects on A1C and Weight (11)
A majority of adults who were placed on injectable semaglutide for diabetes management achieved a target A1C under 7% and were able to maintain it.
- Dose specific effects on A1C were as follows:
- 0.5mg dose injection yielded a 1.4% decrease
- 1.0mg dose injection yielded a 1.6% decrease
- 2.0 mg dose injection, in combination with diabetes pills, yielded a 2.1% decrease in A1C.
Adults taking semifluid injectables for diabetes management also noted weight loss.
- 8-pound weight loss reported with 0.5mg dose injection
- 10 pounds weight loss reported with 1.0mg dose injection
- Up to 14 pounds of weight loss reported with a 2.0mg dose injection

Prescribing insights: Long-Term therapy for a chronic condition?
Semaglutide is viewed favorably as a treatment option for Type 2 diabetes. It appears to lower A1C levels and body weight in the majority of patients, lowering their risk of future cardiovascular events.
The question of long-term medication use, for a chronic health condition, is being heavily discussed in the media. While a percentage of people can decrease or eliminate the need for chronic medications through significant lifestyle changes, there have been reports of weight gain in those who stopped taking this injectable medication.
Without intense lifestyle behavior modification education, there is a heightened risk of weight regain in the absence of such medications. Leaders in the treatment of obesity and related illnesses have commented that this drug is intended for long-term use.
Examples of this include the following:
“GLP-1 medications [like Ozempic] are designed to be taken long-term... They are chronic medications for the treatment of chronic conditions (both diabetes and obesity) (12)". - Christopher McGowan, M.D., a gastroenterologist specializing in obesity medicine and endobariatrics
“As with many chronic conditions, most people who use the drugs for diabetes or weight loss will need to keep taking them to keep benefiting from them. Depending on your individual situation, and without sustained lifestyle changes, it is likely you would need to be on these medications indefinitely to maintain weight loss (13)." - Dr. Cecilia Low Wang, a UCHealth expert in endocrinology, diabetes and metabolism.

Cost Concerns
At this time, injectable semaglutide, FDA-approved for the treatment of Type 2 diabetes, has a self-pay price tag of $935.77 per month (4 injections). With FDA approval, many people with diabetes, insured under commercial plans, receive the drug for the cost of their copay. Those patients without coverage may use pharmacy discount cards that reduce the price, on average, to $814.55/month.

Emerging Concerns: Semaglutide and gastroparesis
In August 2023, a first-of-its-kind lawsuit was filed in Louisiana, against the makers of semaglutide. The lawsuit states the makers of this injectable drug did not adequately warn patients about the risk of severe gastrointestinal issues/possible gastroparesis.
The plaintiff in this case had used both Ozempic and Mounjaro and experienced repeated episodes of severe gastrointestinal events, warranting trips to the emergency room and additional medications to alleviate her symptoms (14). While this lawsuit is in the developing stages, it bears mentioning in terms of concerns over long-term usage of the drug and possible complications.
While the drug labeling for semaglutide (Ozempic) does not specifically mention gastroparesis, the semaglutide/Mounjaro drug label does state that the drug has not been studied in patients with severe gastrointestinal disease and is therefore not recommended in these patients.
Up to 50% of people with diabetes have some degree of delayed gastric emptying, but most have no digestive symptoms or have only mild symptoms. For some people with diabetes, problems managing blood glucose levels may be a sign of delayed gastric emptying (15).
Healthcare providers should evaluate all patients with diabetes for possible symptoms of underlying gastroparesis, such as the feeling of fullness shortly after beginning a meal, or the inability to finish a regular meal. Other symptoms of gastroparesis may include abdominal pain, nausea, bloating, vomiting, and anorexia.
Diabetes and gastroparesis
Uncontrolled or poorly controlled diabetes can affect nerve endings systemwide. Diabetes is a very common cause of gastroparesis. Although the condition is rare it occurs more often in people with chronic conditions such as diabetes, autoimmune diseases, and nervous system disorders. Nerve endings are injured or damaged, cease to function properly, and result in delayed gastric emptying. The delay in gastric emptying can cause various symptoms, such as nausea, vomiting, bloating and distension, abdominal pain, and poor appetite.
In addition to underlying medical conditions, some medications may cause symptoms of gastroparesis (delays in gastric emptying and overall gastric motility. These medications include narcotics, antidepressants, and anticholinergics.
Left untreated, diabetic gastroparesis may lead to malnutrition, electrolyte imbalances, and poor glucose management and control.

Diabetes Lifestyle changes: Patient education (16)
- Weight Management
- Healthy Eating
- Physical Activity
- Smoking Cessation
- Stress Management
The importance of patient education regarding lifestyle changes is a priority. As with any chronic medication condition, the patient and their family/support system must be given every opportunity to educate and empower themselves on self-management of their disease process. Patients must be given the benefit of the doubt that they can indeed embrace their health and well-being and work with their healthcare provider in maximizing their health outcomes.
For diabetes mellitus, numerous lifestyle behaviors should be addressed and actively worked on, so that the patient receives the maximum health benefits. The following lifestyle behaviors are in no particular order; they all warrant discussion at every office visit.
Diet
A person with diabetes should be educated on the effects of food and nutrition on their glucose level. Referrals to a dietitian/nutritionist or Certified Diabetes Care Education Specialist (CDCES) should be considered a top priority. Well-balanced nutritional intake, appropriate carbohydrate awareness, calorie monitoring if weight loss is appropriate to your specific patient) and medication/food interactions are all essential aspects of dietary lifestyle education. Many commercial insurance plans, as well as hospital community outreach programs, offer diabetes self-management classes.
Activity (17)
The CDC recommends a target goal of 150 minutes weekly, Patients should be educated on the positive effects of daily activity on overall health and well-being, stress management, and metabolism. Patients should find activities they are genuinely interested in, involve family and friends, and slowly build greater endurance through increased intervals of longer duration.
Sleep hygiene (18)
Patients should be educated on the positive effects of a good night’s sleep. The aim should be approximately 7-8 hours of restful sleep. Electronics should be powered down and (optimally) removed from the bedroom. A dark, well-vented, cool room temperature is encouraged, and large meals and late-evening caffeine should be avoided.
Medication adherence/ literacy
Medication education is critical to the health and well-being of a patient. Routine education of the patient, and family members or support systems when available, should be supportive and patient-specific. Patients should be assessed on language barriers, literacy issues, and related comprehension concerns. Medication education should include effects, side effects, treatment goals, and sick day management. Emergency care issues should also be discussed. Any monitoring equipment (continuous glucose monitors, accuchecks, lancets) should be reviewed with patients and confirmed with return verbalization and demonstration.
As discussed in this course, patients with chronic diseases must learn self-management techniques to optimize their health and well-being. They must become confident in their understanding of their disease process and take ownership of their health. In doing so, they minimize the risk of long-term complications, improve their self-worth, and actively invest (both time and money) in their future.

Medication Assisted Treatment
Introduction
Medication Assisted Treatment (MAT) is a treatment modality for substance use disorders. It combines counseling and behavioral therapies for addiction with medications used carefully to reduce the physical symptoms of cravings and withdrawal and assist clients in the recovery process. With half of people 12 and older reporting use of an illicit substance at least once and 21 million Americans experiencing addiction, this is an important and relevant topic (4).
Historically, an intense stigma is attached to both addiction and some of the medications used to treat addiction. A thorough understanding of substance use disorders, available MAT therapies, and care of affecting clients are essential topics for nurses to be familiar with, particularly those working in psychiatry, pain management, or addiction medicine.
Overview of Addiction and Substance Abuse:
Drug and alcohol abuse and addiction are chronic, complicated issues involving persistent changes to the brain. There is a stigma or misunderstanding that people with substance abuse disorders can stop any time they want to or lack the willpower or moral fortitude to stop using. This is entirely untrue, and even people who are "recovering" and have not had any drugs or alcohol in years can easily relapse into addiction once those brain changes have occurred (5).
When a person uses drugs or alcohol, the brain's reward center is flooded with dopamine. This provides a "buzz" or pleasurable sensation that may create the desire to use more of the same substance. Over time, and with regular use of the substance, the brain becomes accustomed to the flooding of dopamine and reduces the reward response, a process known as tolerance.
It will now take the same person a more significant amount of the substance to achieve the same "buzz" or "high" they used to feel. This process can also dull the pleasure response to activities not involving substance use, such as food, socialization, or sexual activity. Over time, the chemical changes in the brain can progress to include decreased functioning of learning, decision-making, judgment, response to stress, memory, and behavior (5).
To understand substance abuse disorders, it is first essential to understand some basic definitions. These terms are sometimes used interchangeably, but they mean different things and represent different stages of disease.
Definitions
Substance Use: Substance use is any consumption of drugs or alcohol, regardless of frequency or amount. An occasional glass of wine or taking an edible at a party is an example of substance use. Substance use does not cause problems or dependency in many people (5).
Substance Abuse: Substance abuse is the continued use of drugs or alcohol, even when they do cause problems. Conflict or problems at home, school, work, or legal issues related to the use of drugs or alcohol are signs of abuse. For example, being sent home from school for smoking in the bathroom or failing a drug test at work (5).
Substance Dependence or Addiction: Dependence and addiction can be used interchangeably or is sometimes called substance use disorder. Addiction occurs when a person cannot stop drinking or using drugs despite creating problems in their life. People who are addicted may experience cravings until they use a specific substance, or they may experience uncomfortable physical symptoms, known as withdrawal if they do stop (5).
The American Psychiatric Association (APA) utilizes the following criteria to diagnose clients who suffer from addiction. The more criteria a client answers yes to, the greater their problem with substance use.
Six or more positive criteria are indicative of addiction.
- Using substance in more significant amounts or for more extended periods than intended
- Trying to stop using but being unable to
- Increased amounts of time getting, using, or recovering from use of the substance
- Experiencing cravings or urges to use.
- Continuing to use the substance despite problems with relationships or social situations.
- Missing work, social, or recreational obligations or activities because of substance use
- Participating in risky behavior because of substance use
- Continuing to use the substance despite psychological or physical health problems.
- Needing to use more substance over time to achieve the desired effect.
- Experiencing withdrawal symptoms when stopping the substance (1).

Substance Abuse Statistics
Many factors go into gathering data on substance abuse disorders, from underreporting, the nuance between use, abuse, and addiction, and the large variety of substances available, with the legality of some substances varying by state or age.
The statistics below from 2020 are not meant to be an exhaustive list of substance use disorders in this country but rather an overview of some of the more prevalent addiction-related issues.
- 50% of people 12 years and older have used an illicit substance at least once.
- 5% of Americans 12 years and older have used drugs within the last month.
- This is a 3.8% increase from the previous year.
- About 50% of Americans 12 and over drink alcohol
- 4% of those people have an alcohol use disorder.
- About 20% of Americans use tobacco products or vape
- 18% of Americans over 18 used marijuana in the last 12 months
- 30% of those have some level of misuse or addiction.
- Marijuana is commonly involved in polysubstance use, paired with alcohol or other drugs.
- 7% of Americans over 12 misused opioids in the last 12 months
- 96% of those used prescription pain relievers
- Opioid prescriptions peaked in 2012, with 81.3 prescriptions per 100 people.
- The rate has declined recently due to increased attention to this crisis.
- In 2018, the rate was down to 51 prescriptions for every 100 people
- Fentanyl is now rising as a new and deadly concern.
- 5 million prescriptions were written for fentanyl in 2015.
- Fentanyl is involved in 53% of overdose deaths.
- 7% of all Americans misuse a prescription drug.
- 1% of those misuse stimulants
- 2% of those misuse sedatives
- 5% misuse painkillers
- Over 70,000 drug overdose deaths occur annually in the United States (4)
Risk Factors
A combination of factors is involved in the risk of addiction, and no one factor can determine if someone will develop addiction or after how many uses this will occur.
The addiction process does occur more easily or progresses more rapidly for people with certain risk factors, including:
Genetics
There is a strong genetic correlation with addiction, indicating that biology plays a significant role in the disorder. Family history of addiction, gender, ethnicity, and comorbid mental health conditions can all influence the risk of addiction. (5)
- Children of addicts are eight times more likely to develop an addiction at some point.
- In 2020, among those using illicit or misusing prescription drugs, 22% were male and 17% female.
- Only 20% of users in drug treatment programs are women.
- 9% of people with substance abuse disorders also have at least one mental health disorder (4)
Environment/Non-Genetic Demographics
The attitudes about drugs and alcohol from those in a person's network and life experiences play a role in the risk of addiction. Substance use among friends, family, or coworkers increases the risk that a person will also use substances. Exposure to substance use from a young age relaxed parental attitudes about substance use, and peer pressure from friends can increase the risk. Certain stressful life circumstances such as veteran status, history of sexual or physical assault, or being part of the LGBTQ community can also increase risk. (5)
- 20% of people in urban areas used illegal drugs in 2020 compared to 5% in rural locations.
- 51% of Americans with an illegal pain relief medication obtained it from a friend or relative.
- 7% of LGBTQ Americans abuse illicit drugs.
- 2% of LGBTQ Americans abuse alcohol.
- 7% of Veterans abuse illicit drugs.
- 80% of Veterans abuse alcohol (4)
Developmental Stage
Substance use at any age can lead to addiction, but children and teens are at particular risk due to their underdeveloped brains. The parts of the brain responsible for decision-making, risk assessment, and self-control do not fully develop until the early 20's, putting teenagers at increased risk of dangerous behaviors. In addition, the effects of drugs and alcohol on the developing brain may mean that those parts of the brain never fully develop at all for teens with substance abuse disorders. (5)
- 70% of users who try an illegal substance before age 13 will develop a substance use disorder within the next seven years.
- This is for only 27% of people who first try an illegal substance after age 17.
- 47% of youths report trying an illegal substance by the time they graduate high school (4)

Overview of Medication Assisted Treatment (MAT)
Treatment of substance abuse disorders is a complex and often tumultuous process. The nature of the brain changes that occur during addiction means that a person is never entirely "cured" but will always be considered "recovering" as the risk for relapse is always present. Effective treatment must be multifaceted and often involves removing triggers (such as people, places, and stressors) that may prompt a person to use again behavioral therapy, and medications to curb withdrawal symptoms and reduce cravings.
Medication Assisted Treatment (MAT) is a treatment that involves FDA-approved medications, in combination with behavioral therapy, in the recovery process for substance abuse disorders. Several medications are available for MAT, and evidence continues to emerge that the treatment is highly effective if used correctly.
However, it is a vastly underused and understudied treatment modality. MAT has been available in some form for over 50 years but is just starting to gain traction among the medical community (and policymakers) in recent years, with the federal government calling for more research and increased accessibility for the treatment (8).
The height of the opioid crisis in the last several years has highlighted the magnitude of drug addiction and deaths in the United States, bringing renewed attention to MAT as a treatment option. So, how does MAT work? Prescription medication is given to both stimulate the receptors seeking the abused substance and block the drug's euphoric effects.
Over time, this normalizes brain chemistry and helps the person break the habit of using without the discomfort of cravings and withdrawal symptoms. Gradually, the prescription medication dosage is reduced, all the while in conjunction with behavioral therapy and lifestyle changes, and eventually, the client should be able to stop the medication altogether, often within 1-3 months (8).
MAT does require close supervision by a trained medical professional and an appropriate facility for treatment. It can be done on an inpatient, partial inpatient, or outpatient basis. There may be side effects to the medication, and there is a risk of misusing or developing addiction to the new drug, though the successful outcomes often outweigh this risk. Clients must also participate in behavioral therapy for a comprehensive and effective treatment plan. As with any treatment regimen, careful consideration of the client's history and circumstances is essential (8).

Pharmacokinetics
Currently, there are three medications with FDA approval for MAT: buprenorphine, methadone, and naltrexone. Each will be discussed in depth below.
Buprenorphine
Mechanism of Action and Metabolism
Buprenorphine is an opioid partial agonist, acting on the same receptors as other opioids but with weaker effects. It can be used for the treatment of misuse of opioids, including:
- Heroin
- Fentanyl
- Oxycodone
- Hydrocodone
- Morphine
- Methadone (3)
Opiate receptors are G-protein coupled receptors (GPCRs) with four major types: Mu, Delta, Kappa, and opioid receptor like-1 (ORL1). Stimulation of these receptors results in varying levels of the following effects:
- Euphoria
- Relaxation
- Pain relief
- Sleepiness
- Sweating
- Constipation
- Impaired concentration
- Reduced sex drive (3)
Buprenorphine has a high affinity to the Mu-opioid receptor and is a partial agonist at this site, causing reduced opioid effects with a plateau or ceiling at higher doses. This limits dangerous effects and makes overdose unlikely. It also has slow dissociation from the site, allowing milder and more easily tolerated withdrawal effects compared to full agonists like morphine and fentanyl. Buprenorphine is also a weak kappa receptor antagonist and delta receptor agonist, reducing the craving sensation and improving tolerance to stress (3).
Buprenorphine has poor bioavailability when given orally due to the first-pass effect, where most of the drug is broken down in the liver and intestines. Because of this, sublingual or buccal are the preferred routes of administration and the most common forms in which the drug is manufactured. Transdermal patches and IV and IM forms exist, though not for use in MAT (3).
CYP34A enzymes break down buprenorphine, so other drugs, such as ketoconazole, may inhibit metabolism and increase available levels of buprenorphine. CYP34A inducers such as carbamazepine, topiramate, phenytoin, and barbiturates may speed metabolism and lower available levels. Once broken down, the med takes the form of norbuprenorphine and is excreted in the feces (3).
Available Forms
Buprenorphine is available by itself and with naloxone (in a 4 to 1 ratio). However, in oral form, naloxone is not readily absorbed, and buprenorphine is the only genuinely active ingredient. This combination is beneficial should clients try to inject their buprenorphine to get high; naloxone is a fast-acting opioid antagonist that is active when used intravenously and would block the opioid effect of buprenorphine, rendering it useless for recreational use and ensuring it has no street value.
The currently available preparations of buprenorphine for MAT include:
- Generic Buprenorphine/naloxone sublingual tablets
- Subutex - Buprenorphine sublingual tablets
- Suboxone - Buprenorphine/naloxone sublingual films
- Zubsolv - Buprenorphine/naloxone sublingual tablets
- Bunavail - Buprenorphine/naloxone buccal film (3)
Sublingual products dissolve within 2-10 minutes. Bloodstream absorption begins quickly, bypassing the first pass effect. Buprenorphine has a slow onset of action, peaking about 3-4 hours later. Metabolism is also slow, with the half-life lasting anywhere from 25 to 70 hours (an average of about 38 hours). This long half-life means the drug can be spaced out to every other day administration once weaning begins (3).
Dosing and Monitoring
Clients prescribed buprenorphine must stop using opioids for at least 12 to 24 hours before the first dose; this varies depending on which opioid they are stopping. For short-acting opioids like heroin and oxycodone, buprenorphine may be started 6-12 hours after the last dose. With longer-acting opioids such as morphine or extended-release preparations of oxycodone, buprenorphine should be delayed for about 24 hours. For the longest action opioids, fentanyl patch, 48 -72 hours must be between the last dose and buprenorphine initiation (3).
This initiation schedule means clients will be in the early stages of discomfort and withdrawal. Administration of buprenorphine when clients still have opioids in their bloodstream will lead to competition for receptor sites, rapidly replacing the opioid with buprenorphine and causing acute and more severe withdrawal symptoms.
Depending on the severity of a client's addiction, they may complete the first step of abstaining and withdrawal in an inpatient setting. Once the initial withdrawal symptoms have passed and the initial dose of buprenorphine has been given, the client may be discharged home to continue buprenorphine initiation on an outpatient basis (3).
Initial doses are typically 2-4mg, with up to 4mg given to clients used to higher potency or larger doses of opioids. The dose is gradually increased to meet the client's individual needs, with a maximum dosage of 24mg per day. The average client requires 8-12 mg per day and can reach this dose within the first 2-4 days. It is recommended that doses be supervised by a pharmacist at the dispensing pharmacy for the first two months of treatment to ensure compliance and clients are less likely to relapse (3).
The length of treatment with buprenorphine depends on each client's case and, for some, may be indefinite. Clients who do wish to wean off buprenorphine can begin the process once they are stable and experiencing few or no cravings, and a minimum of 8 weeks from treatment initiation. Doses are moved to alternating days and eventually discontinued altogether (3).
Side Effects and Contraindications:
As with any medication, there are potential side effects, including:
Common Side Effects
- Nausea
- Vomiting
- Drowsiness
- Dizziness
- Headache
- Memory loss
- Sweating
- Dry mouth
- Miosis
- Postural hypotension
- Sexual dysfunction
- Urinary retention
Serious side effects
- CNS depression
- QT prolongation
- Reduced seizure threshold
- Potential for abuse or overdose (3)
Buprenorphine is contraindicated for clients with a past hypersensitive reaction to it. It should be used cautiously for clients with respiratory suppression, older adults, or for those with liver pathologies. Regular monitoring of liver enzymes via lab work is essential (3).
It is a Category C medication for pregnancy, and the risks versus benefits should be carefully weighed. Buprenorphine does cross the placenta and increases the risk of withdrawal symptoms and neonatal abstinence syndrome (NAS) after delivery. However, for pregnant clients with the highest risk of relapse and abuse of opioids, evidence does support that continuation of buprenorphine during pregnancy may improve maternal and fetal outcomes (3).
Buprenorphine may be abused by crushing tablets, snorting the powder, or dissolving it into an injectable solution. Safety measures against this include supervised administration by a pharmacist and the addition of naloxone, which blocks the buprenorphine effects. While the effect ceiling of buprenorphine makes overdose difficult, combining the drug with benzodiazepines, alcohol, or other drugs can compound the CNS depressant effects and increase the risk of overdose (3).
Clinicians need to have a comprehensive health history of clients before initiating buprenorphine so that all risks and potential interactions can be addressed appropriately.
Role of the Pharmacist
Pharmacists play a significant role in the success of MAT involving buprenorphine. Outpatient doses are monitored by the dispensing pharmacist daily, with at-home quantities being allowed on a limited basis (such as weekends or travel) and only for the most motivated and compliant clients. Vital signs are collected before each dosage, with careful monitoring for hypotension or bradypnea. The dose may be skipped for clients who experience excessive side effects, and the client can return the next day for their dose.
Clients presenting with signs of overdose (usually to the ED) may receive naloxone, which will reverse overdose symptoms within 1 hour. Overdose symptoms include dizziness, pinpoint pupils, hypotension, bradypnea, hallucinations, seizure, or unconscious state.
If a client misses a dose, does not show up for it, or is experiencing significant side effects from buprenorphine, the prescribing clinician should be notified so that the treatment plan can be revisited and revised if needed (3).
Considerations for the Prescriber
When considering which medication to prescribe for MAT, prescribers should understand that buprenorphine offers advantages over methadone.
- Lower risk of abuse
- Safer, including at higher doses.
- Therapeutic dose achieved quickly.
- Easier to taper.
- Can be obtained from any provider rather than a methadone clinic.
- Less stigma
The cost of a 30-day supply is around $300. Buprenorphine/naloxone combinations are a little more expensive at $400/month. While prior authorization is usually required, most commercial insurance and state Medicaid programs will cover the medication.
Buprenorphine is a Schedule III Controlled Substance; however, recent federal regulations have been aimed at approving access to MAT, and any provider with an active DEA license may prescribe buprenorphine as allowed by state regulations. Specialized clinics are not required (as they are with methadone), and it is dispensed at regular pharmacies.
Prescribers are encouraged to participate in additional training about MAT with buprenorphine, but it is not required. Detailed documentation must be completed, including the reason for prescribing, start and end dates of treatment, the pharmacy used, the credentials of who will supervise administration, and frequency of follow-up and compliance monitoring. The sublingual and buccal routes are the only forms of medication used for MAT; patches, IM, and IV preparations are not routinely used for MAT.
The success of buprenorphine treatment depends on the client's education. Addiction potential, risk of combination with other CNS depressants, and side effects vs. signs of overdose should all be discussed with clients and their support system (3).

Methadone
Mechanism of Action and Metabolism
Methadone is a synthetic opioid and a full agonist of the Mu-receptor site, stimulating the same effects as opioids.
- Euphoria
- Analgesia
- Sedation
It can be used as a potent analgesic for pain not responding to traditional medications, such as in clients with cancer or terminal illness, as well as for MAT and neonatal abstinence syndrome (NAS).
For this course, it will be discussed as a MAT agent, used in treatment for clients addicted to opioids such as:
- Heroin
- Fentanyl
- Oxycodone
- Hydrocodone
- Morphine
- Hydromorphone (2)
Methadone is a full agonist at the Mu-receptor, meaning it is a more potent and more easily addictive medication than partial agonists like buprenorphine. Methadone has a long half-life (8-60 hours), occupying the Mu-receptors and blocking short-acting opioids from making a client high. The longer half-life also leads to less severe cravings and withdrawal symptoms. Methadone is also an antagonist to the N-methyl-d-aspartate (NMDA) receptor, which adds to its pain relief action (2).
It has high oral bioavailability, is active in the bloodstream within 30 minutes of ingestion and remains elevated for around 24 hours. It is broken down via CYP3A4 and CYP2B6 enzymes and metabolized through the liver, making it a good option for clients with renal problems.
Medications such as ciprofloxacin, benzodiazepines, fluconazole, cimetidine, and fluoxetine may slow methadone metabolism, increasing the available drug and the side effects of overdose risk. Other medications may speed metabolism and decrease the effects of methadone, including phenobarbital, phenytoin, rifampin, ritonavir, and carbamazepine (2).
Available Forms
Methadone is available in many forms, including oral, IM, subcutaneous, IV, and intrathecal, though only the oral is typically used for MAT.
- Methadone - tablets
- DISKETS - dispersible/dissolvable tablet
- Methadone HCL Intensol - 10mg/ml suspension
- Methadone - dispersible tablet (2)
Dosing and Monitoring
Oral dosing is initiated at 30-40 mg/day with a slow titration of 10-20 mg/week until the optimal dosage is reached. The optimal dosage varies by client and depends on the drug they are replacing, tolerance to opioids, and side effects experienced. A dosage between 80- 150 mg/day is the typical goal. (2)
If parenteral methadone is given, it is usually 50%-80% of the oral dosage.
Blood sugar, EKG, and methadone blood levels should be checked regularly, every week for higher-risk patients, and every 3-6 months for those in good health and compliance. The target methadone blood level is around 400 ug/ml (2).
Side Effects and Contraindications
Potential side effects are directly related to stimulation of the opioid receptors and include:
- Diaphoresis
- Flushing
- Pruritus
- Nausea
- Dry mouth
- Constipation
- Sedation
- Lethargy
- Respiratory Depression
- QT prolongation
- Hypoglycemia (2)
Methadone should be considered with a comprehensive view of a client's health history and other medications. Clients with CNS-related disease processes (trauma, increased ICP, dementia, or delirium) must be monitored closely or have other medication considered.
Methadone should not be used simultaneously as other opioids, benzodiazepines, alcohol, or antipsychotics due to increased CNS effects. Methadone is a Pregnancy Category C medication, and risks versus benefits should be weighed carefully. Infants exposed to methadone in utero are at increased risk of NAS after delivery (2).
Overdose can occur, and clients and support systems should be educated on signs of overdose.
- Lethargy
- Somnolence
- Stupor
- Coma
- Miosis
- Bradycardia
- Hypotension
- Respiratory sedation
- Cardiac arrest
Naloxone is used to reverse overdose (2).
Considerations for Prescribers and Clinics
Methadone is a Schedule II Controlled Substance, meaning it has a high abuse potential and must be carefully monitored. The Prescription Drug Monitoring Program (PDMP) is an electronic database used nationwide to register the distribution of controlled substances so that clients do not seek care at multiple clinics or pharmacies to obtain more of a controlled substance.
When prescribing methadone, providers should check the PDMP for both methadone and other prescription opioids so that they are fully aware of other medications clients may be receiving from other places. Regular urine drug screening should be performed to make sure clients are not using other substances not obtained by prescription and that they are testing positive for methadone, meaning they are genuinely taking it if administration is not observed (2).
At the beginning of treatment, methadone is given in the office under a nurse's supervision, and then clients are monitored for adverse effects. Some take-home doses (up to 7 in the first two weeks) may be arranged for weekends or during travel, but this possibility is limited during the first few weeks of treatment. As treatment progresses and compliance is demonstrated, clients may self-administer more doses at home (up to 28 doses per month) and go longer between visits to the clinic. The total length of treatment varies but is often 1-2 years and can even be indefinite (7).
There are methadone clinics that work entirely in the scope of addiction management, but primary care providers may prescribe methadone as well. Prescribers must have an active DEA license and comply with state-based controlled substance regulations (2).

Naltrexone
Mechanism of Action and Metabolism
Naltrexone has been in use since the 1960s and is an opioid antagonist. It competes primarily with the mu-receptor but also serves as an antagonist at the kappa and delta receptors. As an antagonist, it competes with agonists such as opioids and alcohol and blocks the effects of agonists at those sites.
- Prevents euphoria.
- Prevents intoxication.
- Reduces tolerance (6)
Naltrexone also acts on the hypothalamic-pituitary-adrenal axis, modifying it to reduce cravings and suppress alcohol consumption.
It is FDA-approved for use in clinical practice for the treatment of:
- Alcohol use disorder
- Opioid use disorder (prescription and non)
Naltrexone is absorbed orally and undergoes extensive metabolism via the first-pass effect. However, this does not affect its potency as naltrexone's active metabolite, 6β-naltrexone, acts as a potent opioid antagonist. The medication's half-life is around 4 hours but can last up to 24 hours. If administered parenterally, it bypasses the first pass and is even longer acting, with a half-life of 5-10 days. Naltrexone is excreted by the kidneys (6).
Available Forms
Naltrexone is available in an oral tablet and IM injection. Available preparations include:
- Generic naltrexone tablets
- Revia (oral tablet)
- Depade (oral tablet)
- Vivitrol (solution for IM injection, extended-release) (6)
Dosing and Monitoring
Since naltrexone will compete for and block all opioid receptor sites, the risk for withdrawal symptoms is high, and clients must stop the use of alcohol or opioids for 7-10 days before beginning treatment to lessen the risk of withdrawal symptoms. A naltrexone challenge is recommended at the start of therapy.
This consists of administering small amounts of naltrexone subcutaneously or via IV and monitoring the client and their vital signs for signs of withdrawal, such as:
- Nausea
- Vomiting
- Diaphoresis
- BP changes
- Tachycardia
- Rhinorrhea
- Agitation
- Tremors
- Abdominal pain
- Pupillary dilation (6)
If a client fails the naltrexone challenge and has not been long enough since their last use of alcohol or opioids, the naltrexone initiation should be delayed, and the test should be repeated in 24 hours. If clients tolerate the naltrexone test and the negative result, they may begin naltrexone treatment (6).
For oral tablets, dosing usually starts at 25 mg for the first dose. Clients are observed for withdrawal symptoms and side effects; an additional 25 mg is given 1 hour later. After that, clients take 50 mg per day. Clients may continue with 50mg daily or take 100 mg every other day or 150 mg every 3rd day (6).
Alternatively, naltrexone may be given via IM injection for more extended action, improving compliance and reducing relapse. Particularly for alcohol or heroin dependence, data indicates that the IM route has much higher success rates than the oral route. If a client receives the IM injection, 380 mg is given to the gluteal muscle every four weeks (6).
Side Effects and Contraindications
Most common side effects of naltrexone include:
- GI irritation
- Diarrhea
- Abdominal cramps
- Nausea
- Vomiting
- Hypertension
- Headache
- Anxiety
- Low energy
- Joint or muscle pain
- Nervousness
- Sleep disruption
Less commonly, clients report:
- Loss of appetite
- Constipation
- Dizziness
- Irritability
- Depression
- Rash
- Chills (6)
Caution should be used for clients with liver function issues and renal impairment. It is Category C for use during pregnancy, and the risks versus benefits of use in pregnancy must be carefully considered. It also crosses into breast milk and must be considered carefully.
There is limited data about the overdose of naltrexone, and there may be very few symptoms if an overdose occurs. Clients should be monitored for signs of liver dysfunction, seizures, depression, and suicidal ideations. No antidote for naltrexone is currently available.
Naltrexone is contraindicated for clients who failed a naltrexone challenge, test positive for opioids or alcohol on drug screening, have a history of seizures, or have experienced a past hypersensitivity reaction to naltrexone.
Clients may switch from buprenorphine or methadone to naltrexone at some point in treatment. Both medications are agonists at the opioid receptor sites, so changing to naltrexone (an antagonist) may increase the risk of withdrawal symptoms for the first two weeks of treatment (6).
Considerations for Prescribers
Because naltrexone does not cause any euphoria or "high," the abuse potential is non-existent. It is not a controlled substance and can be prescribed by any clinician with prescriptive authority. However, its use is typically only by those who work in mental health or addiction medicine. Clients can take the medication at home or go to the clinic for IM injections.
Many considerations for naltrexone use center around monitoring for side effects and treatment compliance. Baseline and periodic drug screening and liver function tests are prudent. Clients' support persons should be educated on compliance and signs of relapse. The IM formulation should be considered for those with poor compliance or most at risk for relapse (6).
Self Quiz
Ask yourself...

- How do side effects differ between naltrexone and the agonist medications like methadone?
- What does it mean if a client fails a "naltrexone challenge," and how does this delay their care?
Nursing Considerations
Nurses will encounter clients with addiction and even those receiving MAT in a variety of settings, including:
- Outpatient clinics for routine care of any health issues
- ED admission for acute problems not related to addiction.
- Inpatient hospitalization related to other health problems.
- Outpatient setting for participation in MAT or addiction management.
- ED admission for acute problems related to substance abuse or toxicity of MAT medication.
- Inpatient mental health admission for mental health and addiction issues
Regardless of the setting and if the client is being seen for an addiction issue or something else, it is crucial for nurses to be familiar with MAT medications and how they work to provide safe and competent care. Nurses may need to:
- Administer medication.
- Monitor lab results.
- Observe for side effects, toxicity, or withdrawal symptoms.
- Coordinate care within a multidisciplinary team
- Communicate with therapeutic and nonjudgmental techniques.
Self Quiz
Ask yourself...
- Have you ever cared for a client in a non-addiction setting who had a MAT medication on their drug list?

Case Study
Justin is a 32-year-old male who presents to the ED with nausea, lethargy, and confusion worsening over the last 24 hours. Upon exam, the nurse notes diaphoresis, slurred speech, and pinpoint pupils. His vitals are RR 10, HR 54, BP 82/58, SPO2 97%, Temp 99.0.
He reports taking Wellbutrin 150mg daily for depression and smoking cessation, methadone 100mg daily for history of oxycodone abuse, and was started on ciprofloxacin 250mg BID for a UTI 2 days ago at urgent care.
His labs are significant for a WBC of 15,000 but otherwise regular. He tests positive for methadone, which is expected, but not for other substances. He reports being compliant with MAT and avoiding opioid use for nine months.
It is determined that Justin is experiencing methadone toxicity due to the slowed metabolism of the drug from the combination of methadone and ciprofloxacin. He is given naloxone in the ED, and within an hour, his symptoms have improved significantly, and his vital signs are typical. His antibiotic is switched to cefdinir, and he is discharged home in stable condition with instructions to follow up with his PCP within 1-2 days.
Self Quiz
Ask yourself...
- Given Justin's presentation, how could you differentiate between methadone toxicity and relapse?
- How might Justin's condition have progressed if he had not sought emergency care?
- How would Justin's case have been different if he had not tested positive for methadone?
- In what ways could Justin's care before his ED visit have been improved to avoid this complication?
Conclusion
Substance use disorders are a long-standing and dangerous pathology experienced by millions of people each year. At the same time, the stigma of seeking help for such disorders has been eroding in recent years; there has also been a renewed push by the federal government to address the issue in evidence-based and meaningful ways, with access to effective treatment being at the top of the priority list.
Addiction treatment programs utilizing MAT will likely become much more popular in the coming years, and nurses will be on the front lines of this therapy. For nurses to provide competent and comprehensive care to this client population, up-to-date and accurate knowledge is necessary.
Hypertensive Agents
Definitions
Hypertension – high blood pressure above normal. Normal is considered anything less than 120/80 mmHg [7].
Antihypertensives – medications used to control hypertension and lower blood pressure [7].
Hypertensive crisis – severely elevated blood pressure of either:
- Systolic greater than 180 mmHg
- Diastolic greater than 120 mmHg [19].
Hypertensive emergency – acutely elevated blood pressure with signs of target organ damage [2].

Medications Overview
Antihypertensive medications are used for the treatment of hypertension and are used in both inpatient, outpatient, and emergency settings.
Some of the major antihypertensive medication classes include:
- Diuretics
- Beta-blockers
- Angiotensin-converting enzyme inhibitors
- Angiotensin II receptor blockers
- Calcium channel blockers
- Selective alpha-1 blockers
- Alpha-2 Receptor Agonists
- Vasodilators [3].
Different medical organizations have varying recommendations and hypertension treatment guidelines. Hypertension treatment clinical practice guidelines are available from organizations like the American Heart Association, the American College of Cardiology, and the European Society of Cardiology to name a few [21]. Healthcare providers should be aware of their healthcare institution’s recommendations for clinical practice guidelines and organizations.
All organizational guidelines share the same recommended treatment of starting antihypertensives immediately when:
- Blood pressure is greater than 140/90 mmHg for patients with a history of ischemic heart disease, heart failure, or cerebrovascular disease.
- Blood pressure is greater than 160/100 mmHg regardless of underlying medical conditions [21].
Again, healthcare providers should follow current and evidence-based clinical guidelines for initiating or titrating antihypertensive medications.
While most antihypertensives are prescribed in an outpatient setting, certain antihypertensives are indicated during hypertensive or medical emergencies. For example, intravenous (IV) vasodilators, like nitroprusside and nitroglycerin, and calcium channel blockers, like nicardipine, are used during hypertensive emergencies and crises.

Pharmacokinetics
Diuretics
Diuretics are a class of drugs that help control blood pressure by removing excess sodium and water from the body through the kidneys. There are several varying types of diuretics, some including thiazide, potassium-sparing, and loop, and all work to lower blood pressure differently [3].
Thiazide Diuretics
Thiazide diuretics remove excess sodium and water from the body by blocking the sodium-chloride (Na-Cl) channels in the kidneys’ distal convoluted tubule. As the Na-Cl channel becomes blocked, this inhibits the reabsorption of sodium and water into the kidneys. Concurrently, this causes a loss of potassium and calcium ions through the sodium-calcium channels and sodium-potassium pump [1].
Thiazide diuretics are approved by the Food and Drug Administration (FDA) for controlling primary hypertension and are available via oral route. Some common thiazide diuretics are hydrochlorothiazide, chlorthalidone, and metolazone [3].
When initiating this medication, the healthcare provider should start with the lowest dose, which is usually 25mg daily, and then increase accordingly to aid with blood pressure control or if the patient has excess fluid retention, usually as evidenced by leg swelling or edema [1].
Common side effects of thiazide diuretics include:
- Increased urination
- Diarrhea
- Headache
- Stomach and muscle aches [16].
As thiazide diuretics interfere with Na-Cl, Na-Ca, and Na-K channels, there is an increased potential for adverse effects, including:
- Hypotension
- Hypokalemia
- Hyponatremia
- Hypercalcemia
- Hyperglycemia
- Hyperlipidemia
- Hyperuricemia
- Acute pancreatitis
When prescribing thiazide diuretics, healthcare providers should avoid prescribing thiazide diuretics to patients with a sulfonamide allergy, since thiazides are sulfa-containing medications. Also, they should avoid prescribing these to patients with a history of gout [1].
Additionally, patients can experience a thiazide overdose if they take more than the amount prescribed. Patients with a suspected overdose may experience confusion, dizziness, hypotension, and other symptoms. These patients must seek emergency care and poison control must be alerted [16].
Potassium-Sparing Diuretics
Potassium-sparing diuretics remove excess sodium and water from the body without causing loss of potassium. Depending on the type, they interrupt sodium reabsorption by either binding to epithelial sodium channels or inhibiting aldosterone receptors. When catatonic sodium is reabsorbed, this creates a negative gradient causing the reabsorption of potassium ions through the mineralocorticoid receptor [5].
Potassium-sparing diuretics are approved for controlling hypertension and are usually combined with other diuretics, like thiazide or loop diuretics since they have a weak antihypertensive effect.
Common names of potassium-sparing diuretics are amiloride, triamterene, and spironolactone. These medications are available by either intravenous or oral routes. Spironolactone is commonly used for treating primary aldosteronism and heart failure [5]. Patients should be started on the lowest dose when first prescribing this class of medications.
Common side effects can include:
- Increased urination
- Hyperkalemia
- Metabolic acidosis
- Nausea
[4]
Healthcare providers should avoid prescribing this class of medications to patients with hyperkalemia or chronic kidney disease. They should also be avoided during pregnancy or in patients who are taking digoxin. Since potassium-sparing medications can cause hyperkalemia, periodic monitoring for electrolyte imbalances and potassium levels is necessary [4].
Loop Diuretics
Loop diuretics inhibit sodium and chloride reabsorption by competing with chloride binding in the Na-K-2Cl (NKCC2) cotransporter. Potassium is not reabsorbed by the kidney, which causes additional calcium and magnesium ion loss.
Loop diuretics are FDA-approved for the treatment of hypertension but are not considered first-line treatment. They can also be used for treating fluid overload in conditions like heart failure or nephrotic syndrome [12].
Loop diuretics are available via oral or IV routes and furosemide, torsemide, and bumetanide are common forms [3].
Bioavailability and dosage differ for each type and route of loop diuretics. The bioavailability of furosemide is 50%, with a half-life of around 2 hours for patients with normal kidney function, and dosages start at 8mg for oral medication. Torsemide has a bioavailability of about 80%, a half-life of about 3 to 4 hours, and oral dosages start at 5mg [12].
Common side effects can include:
- Dizziness
- Increased urination
- Headache
- Stomach upset
- Hyponatremia
- Hypokalemia [13].
Loop diuretics can lead to several adverse effects, including toxicity, electrolyte imbalances, hyperglycemia, and ototoxicity. They have a black box warning stating that high dosages can cause severe diuresis. Therefore, electrolytes, BUN, and creatinine values should be monitored closely by a healthcare provider.
People with a sulfonamide allergy may also be allergic to loop diuretics, so this should be avoided if the patient is allergic. Loop diuretics also interfere with digoxin and therefore should be avoided. Other contraindications include anuria, hepatic impairments, and use during severe electrolyte disturbances [12].

Beta-Blockers
Beta-blockers work by reducing the body’s heart rate and thus, lowering cardiac output resulting in lowered blood pressure [3]. The mechanism of action for beta-blockers varies, depending on the receptor type it blocks, and are classified as either non-selective or beta-1 (B1) selective.
Non-selective beta-blockers bind to the B1 and B2 receptors, blocking epinephrine and norepinephrine, causing a slowed heart rate. Propranolol, labetalol, and carvedilol are common non-selective beta-blockers.
Alternatively, beta-1 selective blockers only bind to the B1 receptors of the heart, so they are considered cardio-selective. Some examples include atenolol, metoprolol, and bisoprolol. Sotalol is a type of beta-blocker that also blocks potassium channels and is, therefore, a class III antiarrhythmic [8].
Beta-blockers are not primarily used for the initial treatment of hypertension but can be prescribed for conditions like tachycardia, myocardial infarction, congestive heart failure, and cardiac arrhythmias. It’s also approved for use in conditions such as essential tremors, hyperthyroidism, glaucoma, and prevention of migraines.
Beta-blockers are available in many forms, including oral, IV, intramuscular injection, and ophthalmic drops. Starting dosage and route are determined by the health condition being treated [8].
Common side effects of beta-blockers include:
- Bradycardia
- Hypotension
- Dizziness
- Feeling tired
- Nausea
- Dry mouth
- Sexual Dysfunction
[17]
This class of medications can also lead to more severe adverse effects such as orthostatic hypotension, bronchospasm, shortness of breath, hyperglycemia, and increased risk of QT prolongation, torsades de pointes, and heart block [8]. Healthcare providers should avoid prescribing non-selective beta-blockers to patients with asthma. Instead, they can prescribe cardio-selective beta-blockers for patients with asthma.
Additionally, the use of beta-blockers is contraindicated in patients with a history of bradycardia, hypotension, Raynaud disease, QT prolongation, or torsades de pointes. Healthcare providers must encourage patients to monitor their heart rate and blood pressure and follow administration parameters before taking beta-blockers daily since it decreases their heart rate.
Overdose of beta-blockers is life-threatening and healthcare providers must discuss the symptoms of an overdose and the need for emergency care [8].

Angiotensin-converting Enzyme Inhibitors
Angiotensin-converting enzyme (ACE) inhibitors prevent the body from producing angiotensin, a hormone that causes vasoconstriction. As angiotensin production is reduced, this allows the blood vessels to dilate and therefore lowers blood pressure [3].
Moreover, ACE inhibitors act specifically on the renin-angiotensin-aldosterone system (RAAS) by preventing the conversion of angiotensin I to angiotensin II. It also works to decrease aldosterone, which in turn, decreases sodium and water reabsorption [9].
ACE inhibitors usually end in the suffix -pril and some common examples include lisinopril, benazepril, enalapril, and captopril, and they usually end in the suffix [3].
While ACE inhibitors are approved for treating hypertension, they are also FDA-approved for other uses or combination therapies for medical conditions such as:
- Systolic heart failure
- Chronic kidney disease
- ST-elevated myocardial infarction
One non-approved FDA use is treatment of diabetic nephropathy [9]. This class of medication is available in oral, and IV forms, and dosages are dependent on clinical guidelines, underlying medical conditions, and route.
ACE inhibitors have common side effects, with some including:
- Dry cough
- Dizziness
- Hypotension [9].
This medication can also lead to adverse effects, such as syncope, angioedema, and hyperkalemia [9]. As angioedema is an adverse effect, healthcare providers should understand this class of medications is contraindicated in patients with a history of hypersensitivity to ACE inhibitors.
Additionally, ACE inhibitors are contraindicated in patients with aortic valve stenosis, hypovolemia, and during pregnancy. Individuals with abnormal kidney function should have renal function and electrolyte values monitored. If a patient develops a chronic dry cough, then the healthcare provider should consider another antihypertensive medication class by following current guidelines [9].

Angiotensin II Receptor Blockers
Similar to ACE inhibitors, Angiotensin II Receptor Blockers (ARBs) act on the RAAS by binding to angiotensin II receptors and thus block and reduce the action of angiotensin II. Again, this reduces blood pressure by causing blood vessel dilation and decreasing sodium and water reabsorption [11]. ARBs typically end in the suffix -artan and common names are losartan, valsartan, and Olmesartan [3]. Oral and IV routes of the medication are available and again, dosages are dependent on the medication specifically and form [11].
All ARBs are FDA-approved for the treatment of hypertension, but a select few are approved for treating other medical conditions, such as:
- Candesartan for heart failure
- Irbesartan for diabetic nephropathy
- Losartan for proteinuria and diabetic nephropathy
- Telmisartan for stroke and myocardial infarction prevention
- Valsartan for heart failure and reduction of mortality in patients with left ventricular dysfunction [11].
Although not as common as ACE inhibitors, two side effects of ARBs are dry cough and angioedema.
Other common side effects include:
- Dizziness
- Hypotension
- Hyperkalemia
[11]
Contraindications for use are if the patient is pregnant or has renal impairment or failure. If a patient is on an ARB, the healthcare provider should closely monitor lab values for electrolyte imbalances and kidney function.
Additionally, if a patient is taking lithium, ARBs can increase lithium concentration and therefore, lithium blood concentration should be frequently checked [11].

Calcium Channel Blockers
Calcium channel blockers (CCBs), also known as calcium channel antagonists, act by preventing calcium from entering the smooth vascular and heart muscles. In turn, this reduces heart rate and causes vasodilation [3].
They are further divided into two major categories, non-dihydropyridines and dihydropyridines, where there are differences in the mechanism of action. Non-dihydropyridines inhibit calcium from entering the heart’s sinoatrial and atrioventricular nodes and thus cause a cardiac conduction delay and reduce cardiac contractility.
Alternatively, dihydropyridines do not directly affect the heart but do act as a peripheral vasodilator leading to lowered blood pressure. Both categories are metabolized by the CYP3A4 pathway [15].
Names of non-dihydropyridine CCBs are verapamil and diltiazem. Dihydropyridine CCBs typically end in the suffix -pine and common names are amlodipine and nicardipine. Both categories are available via oral and IV routes for administration. Oral dosages of non-dihydropyridine CCBs start at 30mg daily and dihydropyridine CCBs start at 30mg daily for immediate release [15].
Calcium channel blockers can be used to treat other medical conditions in addition to hypertension and include:
- Coronary spasm
- Angina pectoris
- Supraventricular dysrhythmias
- Pulmonary hypertension
- Hypertrophic cardiomyopathy
Non-dihydropyridine CCBs can cause side effects like bradycardia, and constipation, while dihydropyridine CCBs can cause:
- Headaches
- Feeling lightheaded
- Leg swelling [15].
Both categories pose the risk of potential hypotension and bradycardia, so healthcare providers should closely monitor the patient’s blood pressure and heart rate when initiating or titrating the dosage.
Also, an overdose of this medication can lead to cardiac conduction delays, complete heart block, and cardiovascular collapse. Patients with possible symptoms of overdose should be sent to the emergency room immediately.
Additionally, healthcare providers should avoid prescribing CCBs to people with heart failure and sick sinus syndrome [15].

Selective Alpha-1 Blockers
Selective alpha-1 blockers act on the body’s sympathetic nervous system to lower blood pressure. They prevent norepinephrine from binding to the alpha-1 receptors of the sympathetic nervous system, causing smooth muscle relaxation and vasodilation which leads to lowered blood pressure [18].
Selective alpha-1 blockers are available via the oral route, end in the suffix -osin and examples are doxazosin, terazosin, and prazosin [3]. They are FDA-approved for the treatment of hypertension but are not considered first-line therapy. Additionally, this class of medications may be used to treat benign prostatic hyperplasia. Dosages can start as low as 1mg daily depending on the drug selected.
Common side effects include:
- Hypotension
- Tachycardia
- Dizziness
- Headache
- Weakness [18].
As selective alpha-1 blockers can lead to orthostatic hypotension, the healthcare provider should instruct the patient to take this medication at night. They should also avoid prescribing to the elderly population when able because of hypotension and increased fall risk [18].

Alpha-2 Receptor Agonists
Alpha-2 receptor agonists work by decreasing the activity of the sympathetic nervous system to lower blood pressure. It inhibits adenylyl cyclase and decreases the formation of cyclic adenosine monophosphate (cAMP). Alpha-2 agonists also cause vasodilation by reducing the amount of available cytoplasmic calcium [20].
This class of medications is typically administered via oral route but is also available in intravenous and transdermal forms. Two FDA-approved alpha-2 agonists for hypertension treatment are methyldopa and clonidine and dosages are dependent on the name and route.
Methyldopa is commonly prescribed to patients with hypertension and who are pregnant since it’s safe [20].
Common side effects of alpha-2 receptor agonists are:
- Dry mouth
- Drowsiness
- Fatigue
- Headache
- Sexual dysfunction [3].
Contraindications for use are orthostatic hypotension and autonomic disorders. Healthcare providers must avoid prescribing alpha-2 receptor agonists to individuals taking phosphodiesterase inhibitors [20].

Vasodilators
Vasodilators lower blood pressure by dilating the body’s blood vessels. It binds to the receptors of the blood vessel’s endothelial cells, releasing calcium. Calcium stimulates nitric oxide synthase (NO synthase), eventually converting to L-arginine to nitric oxide. As nitric oxide is available, this allows for GTP to convert to cGMP, and causes dephosphorylation of the myosin and actin filaments. As this occurs, the blood vessels’ smooth muscles relax, leading to vasodilation and lowered blood pressure.
Common vasodilators that act via this pathway are nitrates and minoxidil. Hydralazine is another vasodilator, but the mechanism of action is unknown [10].
Available forms of vasodilators are sublingual, oral, and intravenous. Similar to other classes of antihypertensives, vasodilator dosages depend on the form and treatment setting [10].
Nitrovasodilators like nitroprusside and nitroglycerin are used during hypertensive emergencies. Hydralazine is used for severe hypertension for the prevention of eclampsia or intracranial hemorrhage and minoxidil for resistant hypertension [10] [3].
Side effects for each will vary, but nitrates commonly cause:
- Reflex tachycardia
- Headache
- Orthostatic hypotension
[10]
Common side effects of hydralazine are headaches, heart palpitations, and myalgias. Minoxidil causes excessive hair growth, weight gain, and fluid retention [3]. Additionally, nitroprusside can potentially cause cyanide toxicity.
Vasodilators have varying degrees of contraindications, such as nitrates are avoided in patients with an inferior myocardial infarction. Hydralazine should not be given to patients with coronary artery disease, angina, or rheumatic heart disease. Healthcare providers should be aware of contraindications and monitor patients’ blood pressure and potential side effects [10].

Combination Antihypertensives
Many antihypertensive medications come in combined forms, such as ACE inhibitors and thiazide diuretics, beta-blockers and diuretics, or calcium channel blockers and ACE inhibitors. The mechanism of action for combination antihypertensives depends on the blend of medications [3].
Considerations for Prescribers
This section reviews potential considerations when prescribing antihypertensives.
When prescribing antihypertensive medications, there are several factors that healthcare providers must consider. The route is typically determined by the healthcare setting and dosage by the underlying treatment goals. Again, healthcare providers should follow current guidelines when initiating or titrating antihypertensive medications.
Healthcare providers must complete a thorough health history, and review lab values, and contraindications as mentioned above. Monitoring kidney function and electrolyte values is imperative while any patient is taking antihypertensive medications.
While a single antihypertensive medication is recommended for initial treatment, there are some scenarios where combination therapy or combination antihypertensives are recommended [14].
Healthcare providers should also discuss the potential side effects of antihypertensives with patients and what to do if they are experiencing symptoms. For instance, if a patient reports syncope, they should be advised to go to the emergency room or be seen immediately for further evaluation. Also, healthcare providers must encourage patients to monitor their heart rate and blood pressure at home and abide by administration parameters.
For example, instruct patients who are taking beta-blockers to measure their blood pressure and heart rate before taking their medication. If their heart rate is below 60 beats per minute, then they should not take the medication [14].
If a patient is experiencing side effects from an antihypertensive medication, then another alternative should be selected.

Upcoming Research
This section reviews upcoming research and medications for hypertension treatment.
Research on antihypertensive medications has slowed throughout the years. Some clinical trials were performed on the potential of endothelin receptor antagonists to reduce hypertension. However, some studies found several unwanted side effects, and thus clinical use was stopped for safety reasons.
An endothelin-A and endothelin-B receptor blocker, called aprocinentan, has shown promise for the treatment of resistant hypertension by lowering blood pressure and decreasing vascular resistance.
Research on sodium-glucose transport protein (SGLT2) inhibitors, which are typically used for the treatment of type II diabetes mellitus, is also ongoing. SGLT2 inhibitors may promote blood pressure reduction through diuresis and reduce sympathetic tone [21].

Conclusion
If hypertension is left untreated, it can lead to serious health complications, including death. When selecting antihypertensive treatment, healthcare providers should understand the pharmacokinetics of each drug class along with potential side effects and contraindications. They should also follow current clinical guidelines for an evidence-based approach.

Definition
Migraines are recurrent, pulsating headaches often accompanied by other symptoms such as nausea, sensitivity to light, and sensitivity to sound. According to recent studies by (17), migraines are recognized as a complex neurological disorder involving abnormal brain activity and a cascade of events leading to pain and associated symptoms.
The impact of migraines extends beyond physical pain, influencing various aspects of life, and recent literature by (14) highlights the profound effect on the quality of life, with disruptions in daily activities, work, and social interactions. For example, a professional experiencing frequent migraines might struggle to meet work deadlines and engage in social events. Recent advancements in diagnostic criteria by (15) emphasize the importance of a precise definition to ensure appropriate treatment strategies. Therefore, understanding the definition is crucial for accurate diagnosis and effective communication between healthcare providers and patients.

Asthma Treatment and Monitoring
Introduction
When hearing the phrase asthma, what comes to mind? If you're an advanced practice registered nurse (APRN) with prescriptive authority, you've definitely heard of asthma before. Even as a nurse or maybe before nursing school, conversations about prescription drug use and respiratory health existed every so often.
Presently, patients seek guidance and information on various health topics from APRNs, including medication management and respiratory health. The information in this course will serve as a valuable resource for APRNs with prescriptive authority of all specialties, education levels, and backgrounds, to learn more about medications that can treat and manage asthma.
Defining Asthma
What Is Asthma?
Asthma is a non-communicable chronic health condition that affects the airways of the lungs and affects millions of people nationwide. Asthma is often diagnosed in childhood and can resolve in adulthood or continue for the rest of a patient's life. Several studies postulate the cause of asthma, but there is no definitive cause.
Genetics, age, environmental exposures, smoking, and a history of allergies are thought to play a role in asthma severity and development. Clinical presentation of asthma often includes trouble breathing, chronic airway inflammation, and airway hyperresponsiveness. Assessment for asthma often includes patient history, clinical presentation, spirometry testing, and pulmonary function tests (PFTs).
What Are the Stages of Asthma?
Since asthma is a chronic condition, several established guidelines can be used to determine the severity of asthma and explore possible medication options. Depending on the stage of asthma and patient response to existing therapy, treatment and management vary.
The four stages of asthma include intermittent, mild, moderate, and severe. Based on the 2020 National Asthma Education and Prevention Program (NAEPP) guidelines, here is the standard criteria for what constitutes each stage of asthma (2).
Intermittent asthma is characterized with the following clinical presentation and assessment (2):
- Patient history of respiratory symptoms, such as cough, trouble breathing, wheezing, or chest tightness <2 times a week
- Asthmatic flare-ups are short-lived with varying intensity
- Symptoms at night are <2 a month
- No asthmatic symptoms between flare-ups
- Lung function test FEV 1 at >80% above normal values
- Peak flow has <20% variability am-to-am or am-to-pm, day-to-day
Mild persistent asthma is characterized with the following clinical presentation and assessment (2):
- Patient history of respiratory symptoms, such as cough, trouble breathing, wheezing, or chest tightness 3-6 times a week
- Asthmatic flare-ups may affect activity level and can vary in intensity
- Symptoms at night are 3-4 times a month
- Lung function test FEV1 is >80% above normal values
- Peak flow has less than 20-30% variability
Moderate persistent asthma is characterized with the following clinical presentation and assessment (2):
- Patient history of respiratory symptoms, such as cough, trouble breathing, wheezing, or chest tightness daily
- Asthmatic flare-ups may affect activity level and can vary in intensity
- Symptoms at night are >5 times a month
- Lung function test FEV1 is 60%-80% of normal values
- Peak flow has more than 30% variability
Severe persistent asthma is characterized with the following clinical presentation and assessment (2):
- Patient history of respiratory symptoms, such as cough, trouble breathing, wheezing, or chest tightness continuously
- Asthmatic flare-ups affect activity level and often vary in intensity
- Asthmatic symptoms at night are constant
- Lung function test FEV1 is <60% of normal values
- Peak flow has more than 30% variability
Based on patient history, clinical presentation, and these criteria, treatment can be administered to decrease the symptoms of the patient. If a patient presents with symptoms that are outside of your scope of work or understanding, you can always refer patients to a pulmonologist or asthma specialist.
Often times, more severe cases of asthma and asthma emergencies require increased frequency and dosing of asthma-related medications. Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history, pulmonary function, and health history prior to prescribing asthma medications (1).
What Are Asthmatic Emergencies?
Asthmatic emergencies are if a patient has asthma symptoms that are beyond what they typically experience and are unable to function without immediate medical intervention. Asthma emergencies can occur as a result of a patient being unable to access their asthmatic medications, being exposed to a possible allergen, or being under increased stress on the body.
Asthmatic emergencies often require collaborative medical intervention, increased dosages of medications discussed below, and patient education to prevent future asthmatic emergencies (1).
What If Asthma Is Left Untreated?
Depending on the clinical presentation and severity of asthma, asthma can cause several long-term complications if left untreated. If asthma is not properly managed, several complications, such as chronic obstructive pulmonary disease (COPD), decreased lung function, permanent changes to the lungs' airways, and death can occur (1, 2).
Defining Asthma Medications
What Are Commonly Used Medications to Manage Asthma?
Commonly used medications to manage asthma include inhaled corticosteroids, oral corticosteroids, short-acting beta agonists (SABAs), long-acting beta agonists (LABAs), long-acting muscarinic antagonists (LABAs), adenosine receptor antagonists, leukotriene modifiers, mast cell stabilizers, and monoclonal antibodies. The dosage, frequency, amount of asthma management medications, and medication administration route can all vary depending on clinical presentation, patient health history, and more.
How and Where are Asthma Medications Used?
Asthma medications can be used routinely or as needed for management of asthma symptoms depending on the patient. Asthma medications can be used at home, in public, and in health care facilities. Depending on the specific asthma medication and dosage, these medications can be taken by mouth, by an external device, such as an inhaler, via subcutaneous injection, or via intravenous solution (1).
What Are the Clinical Criteria for Prescribing Asthma Medication?
Clinical criteria for prescribing asthma medication can depend on the clinical presentation of a patient. Assessment of lung health and patient history are essential to determining the dosage and medications needed for adequate asthmatic symptom control.
Clinical guidelines from reputable organizations, such as the National Asthma Education and Prevention Program (NAEPP), the National Institutes of Health (NIH), the Global Initiative for Asthma (GINA), and the American Academy of Family Physicians (AAFP) can provide insight into the latest recommendations for asthma management (1, 2). In addition, local laws or health departments might have recommendations for asthma medication guidelines.
What Is the Average Cost for Asthma Medications?
Cost for asthma medications can significantly vary depending on the type of medication, insurance, dosage, frequency, medication administration route, and other factors. Cost is among a leading reason why many patients cannot maintain their medication regime (3). If cost is a concern for your patient, consider reaching out to your local pharmacies or patient care teams to find cost effective solutions for your patients.

Inhaled Corticosteroids Pharmacokinetics
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.
Drug Class – Inhaled Corticosteroids
Commercially available inhaled corticosteroids include: ciclesonide (Alvesco HFA), fluticasone propionate (Flovent Diskus, Flovent HFA, Armon Digihaler), budesonide (Pulmicort Flexhaler), beclomethasone dipropionate (QVAR RediHaler), fluticasone furoate (Arnuity Ellipta), and mometasone furoate (Asmanex HFA, Asmanex Twisthaler).
Clinical criteria for prescribing an inhaled corticosteroid includes adherence to the latest clinical guidelines, patient medical history, patient clinical presentation, and drug availability (4).
Inhaled Corticosteroids Method of Action
Inhaled corticosteroids have an intricate mechanism of action involving several responses to the immune system. Inhaled corticosteroids decrease the existing initial inflammatory response by decreasing the creation and slowing the release of inflammatory mediators. Common inflammatory mediators include histamine, cytokines, eicosanoids, and leukotrienes. Inhaled corticosteroids can also induce vasoconstrictive mechanisms, which, as a result, can lead to less blood flow, resulting in less discomfort and edema (4).
In addition to anti-inflammatory properties, inhaled corticosteroids can create a localized immunosuppressive state that limits the airways' hypersensitivity reaction, which is thought to reduce bronchospasms and other asthma-associated symptoms. It is important to note that inhaled corticosteroids often do not produce therapeutic effects immediately, as many patients may not see a change in their asthma symptoms for at least a week after beginning inhaled corticosteroid therapy (4).
Inhaled Corticosteroids Side Effects
Every medication has the possibility of side effects, and inhaled corticosteroids are no exception. Common side effects of inhaled corticosteroids include oral candidiasis (thrush), throat irritation, headache, and cough.
Patient education about rinsing their mouth and oral hygiene after use is essential to avoid the possibility of thrush and other oral infections and irritations. More severe side effects can include prolonged immunosuppression, reduction in bone density, and adrenal dysfunction (4).
Inhaled Corticosteroids Alternatives
While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with inhaled corticosteroids, so additional medication, increased dosage, a change in frequency, or a new medication class might need to be considered (4).

Oral Corticosteroids Pharmacokinetics
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.
Drug Class – Oral Corticosteroids
Commercially available oral corticosteroids include methylprednisolone, prednisolone, and prednisone. Clinical criteria for prescribing an oral corticosteroid includes adherence to the latest clinical guidelines, patient medical history, patient clinical presentation, and drug availability (4).
Oral Corticosteroids Method of Action
Methylprednisolone and prednisolone have a method of action as intermediate, long-lasting, synthetic glucocorticoids, have COX-2 inhibitory properties, and inhibit the creation of inflammatory cytokines (5).
Prednisone is a prodrug to prednisolone and has anti-inflammatory and immunomodulating glucocorticoid properties. Prednisone has a method of decreasing inflammation by reversing increased capillary permeability and suppressing the movement of certain leukocytes (6).
Oral Corticosteroids Side Effects
Every medication has the possibility of side effects, and oral corticosteroids are no exception. Methylprednisolone and prednisolone have possible side effects of skin changes, weight gain, increased intraocular pressure, neuropsychiatric events, neutrophilia, immunocompromised state, fluid retention, and GI upset.
Consider monitoring symptoms and overall health of patients on systemic corticosteroids to assess for long-term side effects (5). Prednisone has possible side effects of changes in blood glucose, changes in sleep habits, changes in appetite, increased bone loss, an immunocompromised state, changes in adrenal function, and changes in blood pressure (6).
Oral Corticosteroids Alternatives
While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with oral corticosteroids, so additional medication, increased dosage, a change in frequency, or a new medication class might need to be considered (6).

Short-Acting Beta Agonists (SABAs)
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.
Drug Class – SABAs
Common commercially available SABAs include albuterol sulfate (ProAir HFA, Proventil HFA, Ventolin HFA), albuterol sulfate inhalation powder (ProAir RespiClick, ProAir Digihaler), levalbuterol tartrate (Xopenex HFA), and levalbuterol hydrochloride (Xopenex) (4).
SABAs Method of Action
Short-acting beta-agonists (SABAs) have a rapid onset as broncho-dilating medications. SABAs, especially albuterol in emergent situations, are used often to quickly relax bronchial smooth muscle from the trachea to the bronchioles through action on the β2-receptors.
While SABAs are effective bronchodilators in the short term for asthma symptoms, SABAs do not affect the underlying mechanism of inflammation. As a result, SABAs are often used for short-acting intervals, such as few hours, and have limited capabilities to prevent asthma exacerbations alone (4). SABAs can be administered via meter-dosed inhalers, intravenous, dry powder inhalers, orally, subcutaneously, or via nebulizer.
SABAs Side Effects
Every medication has the possibility of side effects, and SABAs are no exception. Because of the beta receptor agonisms, possible SABA side effects include increased heart rate, chest pain, chest palpitations, body tremors, and nervousness (4). Because of the short half-life of SABAs, chronic side effects are not typically observed.
SABAs Alternatives
While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with SABAs, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Long-Acting Beta Agonists (LABAs)
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.
Drug Class – LABAs
Common commercially available LABAs are salmeterol and formoterol (7).
LABAs Method of Action
Long-acting beta-agonists (LABAs) have a rapid onset like SABAs, but also have a longer half-life. LABAs are used often as asthma maintenance medications to relax bronchial smooth muscle from the trachea to the bronchioles through action on the β2-receptors. While SABAs are effective bronchodilators in the short term for asthma symptoms, LABAs are effective bronchodilators in the long term for asthma symptoms.
Like SABAs, LABAs do not affect the underlying mechanism of inflammation. LABAs can be administered via meter-dosed inhalers, intravenous, dry powder inhalers, orally, subcutaneously, or via nebulizer. LABAs are often effective for 12-hour durations (7).
LABAs Side Effects
Every medication has the possibility of side effects, and LABAs are no exception. Like SABAs, because of the beta receptor agonisms, possible LABA side effects include increased heart rate, chest pain, chest palpitations, body tremors, and nervousness (7). Other more prolonged side effects can include changes in blood glucose levels and changes in potassium levels with prolonged LABA use (7).
LABAs Alternatives
While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with LABAs, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).
In addition, there are combination inhaled corticosteroid/LABA medications that can be considered, such as fluticasone propionate and salmeterol (Advair Diskus, Advair HFA, AirDuo Digihaler, AirDuo RespiClick, Wixela Inhub), fluticasone furoate and vilanterol (Breo Ellipta), mometasone furoate and formoterol fumarate dihydrate (Dulera), and budesonide and formoterol fumarate dihydrate (Symbicort) (4).

Long-Acting Muscarinic Antagonists (LAMAs)
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.
Drug Class – LAMAs
Common commercially available LAMAs include two inhalation powders via inhalers known as tiotropium bromide (Spiriva Respimat) and fluticasone furoate, umeclidinium, and vilanterol (Trelegy Ellipta) (4).
LAMAs Method of Action
Both drugs mentioned above are long-acting muscarinic antagonists (LAMAs). LAMAs work to alleviate asthmatic symptoms by antagonizing the type 3 muscarinic receptors in bronchial smooth muscles, resulting in relaxation of muscles in the airway (4). Because LAMAs are long-acting, they are not recommended for cases of acute asthma exacerbations or asthmatic emergencies (4).
LAMAs Side Effects
Possible LAMA side effects include urinary retention, dry mouth, constipation, and glaucoma (4).
LAMAs Alternatives
While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with LAMAs, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Adenosine Receptor Antagonists Pharmacokinetics
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.
Drug Class – Adenosine Receptor Antagonists
The commercially available adenosine receptor antagonist for asthma management is theophylline as a pill or intravenous (8).
Adenosine Receptor Antagonists Method of Action
The method of action for theophylline is acting as a nonselective adenosine receptor antagonist, acting as a competitive, nonselective phosphodiesterase inhibitor, and reducing airway responsiveness to histamine, allergens, and methacholine (8).
Adenosine Receptor Antagonists Side Effects
Common side effects of theophylline include GI upset, headache, dizziness, irritability, and arrythmias (8).
Adenosine Receptor Antagonists Alternatives
While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with theophylline, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Leukotriene Modifiers Pharmacokinetics
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.
Drug Class – Leukotriene Modifiers
Commercially available leukotriene modifiers include montelukast (Singular) and zafirlukast (Accolate) as oral pills taken once a day. Zileuton (Zyflo CR) is a 5-lipoxygenase inhibitor that also modifies leukotriene activity (4).
Leukotriene Modifiers Method of Action
Montelukast and zafirlukast work to control asthma-related symptoms by targeting leukotrienes, which are eicosanoid inflammatory markers. Montelukast works in particular by blocking leukotriene D4 receptors in the lungs, thus allowing decreased inflammation in the lungs and increased relaxation of lung smooth muscle (9).
Zafirlukast works by being a competitive antagonist at the cysteinyl leukotriene-1 receptor (CYSLTR1) (10). Zileuton is a 5-lipoxygenase inhibitor, in which 5-lipoxygenase is needed for leukotriene creation. Blocking 5-lipoxygenase decreases the formation of leukotrienes at several receptors. As a result of decreased leukotriene production, there is decreased inflammation, decreased mucus secretion, decreased bronchoconstriction (11).
Leukotriene Modifiers Side Effects
Possible side effects of montelukast include headaches, GI upset, and upset. Neuropsychiatric events, such as nightmares, changes in sleep, depression, and suicidal ideation are more severe side effects associated with montelukast.
Possible side effects of zafirlukast include headache, GI upset, and hepatic dysfunction (9).
Possible side effects of zileuton include hepatic dysfunction, changes in sleep, changes in mood, headaches, and GI upset. When the leukotriene modifiers, neuropsychiatric side effects are to be monitored for in particular, especially for suicidal ideation (9,10,11).
Leukotriene Modifiers Alternatives
Some patients might not report their symptoms alleviating with leukotriene modifiers, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Mast Cell Stabilizer Pharmacokinetics
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.
Drug Class – Mast Cell Stabilizer
A commercially available mast cell stabilizer is cromolyn available via metered-dose inhaler and nebulizer solution (12).
Mast Cell Stabilizer Method of Action
Cromolyn has a method of action in which it inhibits the release of inflammatory mediators from cells, such as the release of histamine and leukotrienes (12).
Mast Cell Stabilizer Side Effects
Every medication has the possibility of side effects, and cromolyn is no exception. Common side effects of cromolyn include dry throat, throat irritation, drowsiness, dizziness, cough, headache, and GI upset (12).
Mast Cell Stabilizer Alternatives
While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with mast cell stabilizers, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Monoclonal Antibody Pharmacokinetics
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.
Drug Class – Monoclonal Antibody
Commercially available monoclonal antibodies include Omalizumab (Xolair), mepolizumab (Nucala), reslizumab (Cinqair), benralizumab (Fasenra), dupilumab (Dupixent), and tezepelumab-ekko (Tezspire). Omalizumab, mepolizumab, benralizumab, dupilumab, and texepelumab-ekko are available via subcutaneous injection. Reslizumab is available via intravenous solution (4).
Monoclonal Antibody Method of Action
Omalizumab is an anti-IgE monoclonal antibody that works by inhibiting the binding of IgE to mast cells and basophils. As a result of decreased bound IgE, activation and release of mediators, such as histamine, in the allergic response are decreased (13).
Mepolizumab, reslizumab, and benralizumab are interleukin (IL)-5 antagonists. These IL-5 antagonists inhibit IL-5 signaling, allowing for a decrease in the creation and survival of eosinophils. However, the full method of action for IL-5 antagonists is still unknown, as more evidence-based research is needed (4, 15).
Dupilumab is an IgG4 antibody that inhibits IL-4 and IL-13 signaling by binding to the IL-4Rα subunit. This inhibition of the IL-4Rα subunit allows for the decrease of IL-4 and IL-13 cytokine-induced inflammatory responses (14).
Tezepelumab-ekko is an IgG antibody that binds to the thymic stromal lymphopoietin (TSLP) and prevents TSLP from interacting with the TSLP receptor. Blocking TSLP decreases biomarkers and cytokines associated with inflammation. Knowing this, the full method of action for Tezepelumab-ekko is still unknown, as more evidence-based research is needed4,15.
Monoclonal Antibody Side Effects
Possible side effects of omalizumab include injection site reactions, fracture, anaphylaxis, headache, and sore throat (13). Possible side effects of mepolizumab, reslizumab, and benralizumab include injection site reactions, headache, and hypersensitivity reactions (4). Possible side effects of dupilumab include joint aches, injection site reactions, and headache (14). Possible side effects of tezepelumab-ekko include injection site reactions and headache (14).
Monoclonal Antibody Alternatives
While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with monoclonal antibodies, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Nursing Considerations
Nurses remain the most trusted profession for a reason, and APRNs are often pillars of patient care in several health care settings. Patients turn to nurses for guidance, education, and support. While there is no specific guideline for the nurses' role in asthma education and management, here are some suggestions to provide quality care for patients currently taking medications to manage asthma or concerned about possibly having asthma.
- Take a detailed health history. Often times, respiratory symptoms, such as a cough or trouble breathing, are often dismissed in health care settings, or seen as "common symptoms with everyone." If a patient is complaining of symptoms that could be related to asthma, inquire more about that complaint.
Ask about how long the symptoms have lasted, what treatments have been tried, if these symptoms interfere with their quality of life, and if anything alleviates any of these symptoms. If you feel like a patient's complaint is not being taken seriously by other health care professionals, advocate for that patient to the best of your abilities.
- Review medication history at every encounter. Often times, in busy clinical settings, reviewing health records can be overwhelming. Millions of people take asthma medications at varying dosages, frequencies, and times of day. Many people with asthma take more than one medication to manage their symptoms.
Ask patients how they are feeling on the medication, if their symptoms are improving, and if there are any changes to medication history.
- Be willing to answer questions about asthma, respiratory health, and medication options. Society stigmatizes open discussions of prescription medication and can minimize symptoms of asthma, such as a chronic cough.
There are many people who do not know about medication options or the long-term effects of undiagnosed or poorly managed asthma. Be willing to be honest with yourself about your comfort level discussing topics and providing education on asthma medications and asthma clinical assessment options.
- Inquire about a patient's life outside of medications, such as their occupation, living situation, and smoking habits. Household exposures, such as carpets or pets, can trigger asthma. Occupations with high exposure to smoke can also trigger asthmatic symptoms. Smoking, living with someone who smokes, or residing in an area with high levels of pollution can also influence asthma symptoms.
Discuss possible solutions to help with symptoms, such as improving ventilation, increasing air quality, and mask wearing when possible.
- Communicate the care plan to other staff involved for continuity of care. For several patients, especially for patients with severe asthma, care often involves a team of nurses, specialists, pharmacies, and more. Ensure that patients' records are up to date for ease in record sharing and continuity of care.
- Stay up to date on continuing education related to asthma medications, as evidence-based information is always evolving and changing. You can then present your new learnings and findings to other health care professionals and educate your patients with the latest information. You can learn more about the latest research on asthma and asthma-related medications by following updates from evidence-based organizations.
How can nurses identify if someone has asthma?
Unfortunately, it is not always possible to look at someone with the naked eye and determine if they have asthma. While some people might have visible asthmatic symptoms, such as wheezing or trouble breathing, asthmatic clinical presentation can significantly vary from person to person.
APRNs can identify and diagnose if someone has asthma by taking a complete health history, listening to patient's concerns, and offering pulmonary function testing.
What should patients know about asthma medications?
Patients should know that anyone has the possibility of experiencing side effects medications for asthma management, just like any other medication. Patients should be aware that if they notice any changes in their mood, experience any sharp headaches, or feel like something is a concern, they should seek medical care.
Nurses should also teach patients to advocate for their own health in order to avoid untreated or undetected asthma and possible chronic complications from asthma or asthma-related medications.
Here are important tips for patient education in the inpatient or outpatient setting:
- Tell the health care provider of any existing medical conditions or concerns (need to identify risk factors).
- Tell the health care provider of any existing lifestyle concerns, such as tobacco use, other drug use, sleeping habits, occupation, diet, menstrual cycle changes (need to identify lifestyle factors that can influence asthmatic medication use, asthma severity, and asthma management).
- Tell the health care provider if you have any changes in your breathing, such as pain with deep breathing or persistent coughing (potential asthma exacerbation symptoms or possibility of asthma medications not being as effective for treatment).
- Tell the nurse of health care provider if you experience any pain that increasingly becomes more severe or interferes with your quality of life.
- Keep track of your health, medication use, and health concerns via an app, diary, or journal (self-monitoring for any changes).
- Tell the health care provider right away if you are having thoughts of hurting yourself or others (possible increased risk of suicidality is a possible side effect for montelukast use).
- Take all prescribed medications as indicated and ask questions about medications and possible other treatment options, such as non-pharmacological options or surgeries.
- Tell the health care provider if you notice any changes while taking medications or on other treatments to manage asthma (potential worsening or improving health situation).

SSRI Use in Major Depressive Disorder
Introduction
When hearing the phrase selective serotonin reuptake inhibitors, what comes to mind? If you're an advanced practice registered nurse (APRN) with prescriptive authority, you've heard of SSRIs before. Even as a nurse or maybe before nursing school, conversations about prescription drug use and mental health existed every so often.
Presently, patients seek guidance and information on various health topics from APRNs, including medication management, women's health, and mental health. The information in this course will serve as a valuable resource for APRNs with prescriptive authority of all specialties, education levels, and backgrounds to learn more about SSRIs and major depressive disorder (MDD).
Defining SSRIs
What Are SSRIs?
Selective serotonin reuptake inhibitors, known as SSRIs, are a type of pharmacological drug class. SSRIs have existed for the past several decades as a class of prescription medications that can manage major depressive disorder (MDD) and other mental health conditions (1).
While this course focuses explicitly on SSRI use in MDD management, SSRIs are also Food and Drug Administration (FDA) approved to manage obsessive-compulsive disorder (OCD), panic disorder (PD), post-traumatic stress disorder (PTSD), and social anxiety disorder (SAD). In addition, several off-label uses for SSRI include management for binge eating disorder and menopausal vasomotor symptoms.
How and Where Are SSRIs Used?
SSRIs are commonly prescribed to manage MDD and other mood disorders in the U.S. and around the world in pediatric, adult, and geriatric populations (1, 2). SSRIs can be taken by mouth as a pill, capsule, or liquid oral solution. Presently, SSRIs cannot be offered via intravenous, rectal, buccal, or injection routes.
What Is the Clinical Criteria for Prescribing SSRIs?
Clinical criteria for prescribing SSRIs can vary depending on the intention for the SSRI. In the case of MDD, several factors can play a role in the clinical criteria for prescribing SSRIs. A patient's adherence to swallowing a pill daily, dosage given the patient's weight, medical history, and MDD concerns, and prior experience with other medications can influence prescribing SSRIs. When considering prescribing SSRIs for MDD management, consider assessing the patient for MDD first, taking a detailed health history, and discussing the risk versus benefits of starting SSRIs for this patient (1, 3).
What Is the Average Cost for SSRIs?
Cost for SSRIs can significantly vary depending on the type of SSRI, insurance, dosage, frequency, and other factors. Cost is among leading reasons why many patients cannot maintain their medication regime (4). If cost is a concern for your patient, consider reaching out to your local pharmacies or patient care teams to find cost-effective solutions for your patients.
What Is Major Depressive Disorder (MDD)?
Major depressive disorder (MDD) is a mental health condition in which a person has consistent appetite changes, sleep changes, psychomotor changes, decreased interest in activities, negative thoughts, suicidal thoughts, and depressed mood that interfere with a person's quality of life (5). According to the Diagnostic and Statistical Manual of Mental Health Disorders, a patient must have at least five persistent mood related symptoms, including depression or anhedonia (loss of interest in activities once enjoyed), that interferes with a person's quality of life to be formally diagnosed with MDD. Note that MDD does not include a history of manic episodes, and pediatric populations can present with more variable MDD symptoms (5). As an APRN, you can assess for MDD by doing a detailed patient health history or having a patient complete the Patient Health Questionnaire-9 (PHQ-9) - a depression assessment tool (5).

SSRI Pharmacokinetics
Drug Class SSRIs
Selective serotonin reuptake inhibitors, known as SSRIs, are a type of pharmacological drug class part of the antidepressant drug class. They can be prescribed at various dosages depending on the patient history, severity of major depressive disorder (MDD), other medication use, and other factors based on patient-centered decision making. Currently, SSRIs that are FDA approved for MDD management include paroxetine, sertraline, citalopram, escitalopram, vilazodone, and fluoxetine. SSRIs can be prescribed for the oral route and are available via capsule, tablet, or liquid suspension/solution. SSRIs can be taken at any time of day. They can be taken with or without food, though vilazodone in particular is recommended with food. SSRIs are often prescribed to be taken once a day, sometimes twice a day, depending on the severity of MDD. Health care provider professional discretion and patient condition should guide therapy (1).
SSRIs are metabolized by and known to affect the cytochrome P450 system. CYP2D6 inhibitors include escitalopram, citalopram, sertraline, paroxetine, and fluoxetine. Fluoxetine and fluvoxamine are inhibitors of CYP2C19. Fluvoxamine is an inhibitor of CYP1A2. Consider reviewing a patient's medication history and health history prior to prescribing SSRIs (1).
SSRIs Method of Action
SSRI method of action has been subject to several studies, especially in the last few years. Serotonin is a neurotransmitter that plays a role in mood and other bodily functions. It can be measured in plasma, blood, urine, and CSF (6). It is important to note that serotonin is rapidly metabolized to 5-hydroxyindoleacetic acid (5-HIAA) (6). SSRIs work by inhibiting the reuptake of serotonin at certain chemical receptors, thereby increasing serotonin activity and concentration (1). SSRIs inhibit the serotonin transporter (SERT) at the presynaptic axon terminal.
By obstructing the SERT, a higher amount of serotonin (5-hydroxytryptamine or 5HT) remains in synaptic clefts. This higher amount of serotonin can then stimulate postsynaptic receptors for a more extended period (1). While SSRIs can increase serotonin activity, there is some evidence that suggests the possibility of long-term SSRI use reducing serotonin concentration (6). In addition, the clinical response to SSRIs in patients with MDD can take anywhere from a few to several weeks to emerge (7). While some research suggests that there are initial improvements in mood, evidence remains inconclusive as to the exact time SSRIs can take to provide a therapeutic response for patients (7). Also, while research suggests that SSRIs can increase serotonin levels, there is still mixed evidence on the exact method of action for SSRIs (7).
As a result, it is important to counsel patients that SSRIs can take a few weeks to provide a therapeutic response and to monitor mood and symptoms while taking SSRIs.
SSRI Side Effects
Every medication has the possibility of side effects, and SSRIs are no exception. Fortunately, SSRIs are known to have less side effects than other drug classes of antidepressants, such as monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants (TCAs). The most commonly known side effects of SSRIs include weight gain, sleep changes, headache, gastrointestinal issues, drowsiness, orthostatic hypotension, and sexual function changes (1).
Sleep changes can include an increased desire to sleep, increase in the amount of time sleeping, or insomnia. Gastrointestinal issues can include an upset stomach, nausea, or dry mouth. Mood changes, such as anxiety, are possible side effects as well. Sexual function changes can include erectile dysfunction, libido changes, impaired orgasmic response, and vaginal dryness (1, 8).
There are more serious possible side effects of SSRIs as well. For instance, SSRIs have the possible side effect of QT prolongation, which if left untreated or undiagnosed, can lead to fatal cardiac arrythmias (1, 8). In particular, the SSRI citalopram has been shown to have more of a risk for QT prolongation compared to other SSRIs. Also, like any other medication that can possibly increase levels of serotonin in the body, there is a possibility of serotonin syndrome as a complication of SSRI use. Possible serotonin syndrome clinical manifestations include increased blood pressure, increased sweating, increased reflex ability, and increased dry eyes (8). Due to the wide varied range of side effects, patient counseling, monitoring, and education is essential when prescribing SSRIs.
SSRI Black Box Warning
In 2004, the FDA issued a black box warning for SSRIs and other antidepressant medications due to the possible increased risk of suicidality in pediatric and young adult populations (up to age 25). When considering SSRI use in patients under 25 and knowing MDD is a risk factor for suicidality, having a conversation with the patient about risks versus benefits must be considered. However, in the past several years since the FDA's warning, there is no clear evidence showing a correlation between SSRIs and the increased risk of suicidality (1, 8). Health care provider professional discretion and patient condition should guide therapy.
SSRI Alternatives
MDD can be a complex, chronic condition to manage with varying clinical presentation and influence on a patient's quality of life. There are several alternatives to SSRI use, such as: (1, 9)
- Other prescription drugs
- Serotonin-norepinephrine reuptake inhibitors (SNRIs). Commonly known SNRIs include milnacipran, venlafaxine, desvenlafaxine, duloxetine, and levomilnacipran.
- Atypical antidepressants. Commonly known atypical antidepressants include bupropion and mirtazapine.
- Tricyclic antidepressants (TCAs). Commonly known TCAs include amitriptyline, desipramine, imipramine, clomipramine, doxepin, and nortriptyline.
- Monoamine oxidase inhibitors (MAOIs). Commonly known MAOIs include phenelzine, tranylcypromine, isocarboxazid, and selegiline.
- Psychotherapy, such as cognitive behavioral therapy (CBT) or interpersonal therapy
- Electroconvulsive therapy (ECT)
- Vagus Nerve Stimulation (VNS)
- Transcranial Magnetic Stimulation (TMS)

Nursing Considerations
Nurse’s Role
What Is the Nurses' Role in SSRI Patient Education and Management?
Nurses remain the most trusted profession for a reason, and APRNs are often pillars of patient care in several health care settings. Patients turn to nurses for guidance, education, and support. While there is no specific guideline for the nurses' role in SSRI education and management, here are some suggestions to provide quality care for patients interested in or currently taking SSRIs to manage current or suspected major depressive disorder (MDD).
- Take a detailed health history. Often times, mental health symptoms, such as depressive thoughts or anxiety, are often dismissed in health care settings, even in mental health settings. If a patient is complaining of symptoms that could be related to major depressive disorder, inquire more about that complaint. Ask about how long the symptoms have lasted, what treatments have been tried, if these symptoms interfere with their quality of life, and if anything alleviates any of these symptoms. If you feel like a patient's complaint is not being taken seriously by other health care professionals, advocate for that patient to the best of your abilities.
- Review medication history at every encounter. Often times, in busy clinical settings, reviewing health records can be overwhelming. While a vast number of people take SSRIs, many are no longer benefiting from the medication. Ask patients how they are feeling on the medication, if their symptoms are improving, and if there are any changes to medication history.
- Ask about family history. If someone is complaining of symptoms that could be related to MDD, ask if anyone in their immediate family, such as their parent or sibling, experienced similar conditions.
- Be willing to answer questions about mental health and SSRIs. Society can often stigmatize open discussions of prescription medication and mental health. SSRIs are no exception. There are many people who do not know about the benefits and risks of SSRIs, the long-term effects of unmanaged MDD, or possible treatment options. Be willing to be honest with yourself about your comfort level discussing topics and providing education on SSRIs and MDD.
- Communicate the care plan to other staff involved for continuity of care. For several patients, MDD management often involves a team of mental health professionals, nurses, primary care specialists, pharmacies, and more. Ensure that patients' records are up to date for ease in record sharing and continuity of care.
- Stay up to date on continuing education related to SSRIs and mental health conditions, as evidence-based information is always evolving and changing. You can then present your new findings to other health care professionals and educate your patients with the latest information. You can learn more about the latest research on SSRIs and mental health by following updates from evidence-based organizations.
Identifying Major Depressive Disorder
How can nurses identify if someone has major depressive disorder?
Unfortunately, it is not possible to look at someone with the naked eye and determine if they have MDD. APRNs can identify and diagnose if someone has MDD by taking a complete health history, listening to patient's concerns, having patients complete the PHQ-9 questionnaire and communicating any concerns to other health care professionals (9).
Patient Education
What should patients know about SSRIs?
Patients should know that anyone has the possibility of experiencing side effects of SSRIs, just like any other medication. Patients should be aware that if they notice any changes in their mood, experience any sharp headaches, or feel like something is a concern, they should seek medical care. Due to social stigma associated with mental health and SSRI use, people may be hesitant to seek medical care for fear of being dismissed by health care professionals (1, 6). In addition, side effects (that interfere with the quality of life) are often normalized (1, 6). However, as more research and social movements discuss mental health and SSRI use more openly, there is more space and awareness for SSRI use and mental health.
Nurses should also teach patients to advocate for their own health in order to avoid progression of MDD and possible unwanted side effects of SSRIs. Here are important tips for patient education in the inpatient or outpatient setting.
- Tell the health care provider of any existing medical conditions or concerns (need to identify risk factors)
- Tell the health care provider of any existing lifestyle concerns, such as alcohol use, other drug use, sleeping habits, diet, menstrual cycle changes (need to identify lifestyle factors that can influence SSRI use and MDD)
- Tell the health care provider if you notice any changes in your mood, behavior, sleep, sexual health (including vaginal dryness or erectile dysfunction), or weight (possible changes that could hint at more chronic side effects of SSRIs)
- Tell the health care provider if you have any changes in urinary or bowel habits, such as increased or decreased urination or defecation (potential risk for SSRI malabsorption or possible unwanted side effects)
- Tell the nurse of health care provider if you experience any pain that increasingly becomes more severe or interferes with your quality of life
- Keep track of your mental health, medication use, and health concerns via an app, diary, or journal (self-monitoring for any changes)
- Tell the health care provider right away if you are having thoughts of hurting yourself or others (possible increased risk of suicidality is a possible side effect for SSRI use)
- Take all prescribed medications as indicated and ask questions about medications and possible other treatment options, such as non-pharmacological options or surgeries
- Tell the health care provider if you notice any changes while taking medications or on other treatments to manage your MDD (potential worsening or improving mental health situation)

Antibiotic Use for UTI
Introduction
A urinary tract infection (UTI) can develop in anyone but is more common in females than males. Approximately 40% of American women will develop a urinary tract infection in their lives [2]. Many UTIs can lead to serious health complications, including sepsis and sometimes patient mortality.
Thus, healthcare providers must be knowledgeable of the signs and symptoms of UTIs, the available antibiotics, and UTI treatment guidelines. Understanding the different pharmacokinetics of antibiotics used to treat UTIs is essential during drug selection. This course outlines UTI antibiotic pharmacology and addresses pharmacokinetics, including mechanism of action, side effects, usage, and contraindications.
Definitions
This section covers the definitions related to UTI treatment and management.
Urinary Tract Infection
Bacterial infection of the lower urinary tract (usually confined to the bladder). This is also sometimes called cystitis and is primarily caused by the bacteria E. coli [2].
Asymptomatic Bacteremia
A urine specimen is collected on a patient and shows the presence of bacteria, but they do not have any UTI symptoms [5].
Pyelonephritis
Bacterial infection of the upper urinary tract (i.e. kidneys) [6].
Urosepsis
When a urinary tract infection causes a systemic infection, also known as sepsis [6].

Medications Overview
This section briefly reviews UTI antibiotic classes and medical indications.
Certain antibiotics are used to prevent or treat urinary tract infections and are used in both inpatient and outpatient settings. Healthcare providers should follow current guidelines regarding UTI treatment, which depends on the patient and type of urinary tract infection. UTI treatment algorithms are further divided into:
- Uncomplicated UTIs
- Complicated UTIs
- Prophylactic treatment for recurrent UTIs [6]
What constitutes uncomplicated UTIs are patients who have urinary symptoms, but do not have signs of systemic infections, like fever, flank pain, costovertebral angle (CVA) tenderness, etc. Patients can be male or female, unlike previous guidelines that categorized all males as complicated UTIs. Also, patients with uncomplicated UTIs usually have no underlying health conditions or risk factors that may affect treatment [6].
Conversely, complicated UTIs occur when patients have systemic symptoms. Patients who are pregnant, have a history of UTIs, or who are considered elderly also fall under complicated UTIs. Patients with pyelonephritis are automatically considered as having complicated UTIs as well. Patients with recurrent UTIs may be prescribed certain low-dose antibiotics for prevention [6].
Regardless of the UTI type, below are some of the common antibiotics prescribed:
- Trimethoprim-sulfamethoxazole
- Nitrofurantoin
- Fluoroquinolones
- Ciprofloxacin
- Levofloxacin
- Beta-lactams
- Cephalexin
- Amoxicillin-clavulanate
- Ceftriaxone
- Cefdinir
- Piperacillin-tazobactam
- Meropenem
- Fosfomycin
- Pivmecillinam

Pharmacokinetics
This section discusses the pharmacokinetics of each antibiotic medication used to treat UTIs.
Trimethoprim-sulfamethoxazole
Sulfonamides, also called sulfa drugs, are a class of medications commonly used to treat bacterial infections, including UTIs. A common sulfonamide medication used to treat UTIs is sulfamethoxazole formulated with trimethoprim which is sometimes abbreviated as TMP-SMX, TMP-sulfa, or TMP-SMZ [22]. Trimethoprim-sulfamethoxazole is also approved by the Federal Drug Administration (FDA) to treat chronic bronchitis exacerbations, otitis media in children, and shigellosis.
This medication is also used for prevention and treatment of traveler’s diarrhea, toxoplasmosis, and Pneumocystis jirovecci and Pneumocystis carinii pneumonia. Some other off-label or non-FDA-approved uses are tuberculosis, malaria, listeria, pertussis, and community-acquired pneumonia [10].
Since this a combination medication, TMP-SMX works by two different mechanisms of action. Trimethoprim competes with the enzyme dihydrofolate reductase and subsequently stops the production of tetrahydrofolate from converting to folate.
Sulfamethoxazole, a CYP2CP inhibitor, competes with p-aminobenzoic acid during dihydrofolate synthesis. These two medications combined work against folate production and block bacterial biosynthesis of nucleic acids and proteins. Both medications are metabolized by the liver [10].
TMP-SMX is available via oral and intravenous (IV) forms. Adult TMP-SMX oral dosages are typically 160mg/800mg for the treatment of UTI, respectively, and dosages for children under 40 kilograms are weight-based. This medicaiton is best absorbed orally when taken with at least eight ounces of water. Intravenous TMP-SMX is given to hospitalized patients and dosages will vary. Some common side effects of trimethoprim-sulfamethoxazole include:
- Nausea and/or vomiting
- Rash and photosensitivity
- Dizziness
- Fatigue
- Loss of appetite and anorexia [10]
As this medication’s mechanism of action interferes with folate production, folate deficiency is also common. More severe side effects may include Stevens-Johnson syndrome, anemia, and Clostridioides difficile (C. diff) diarrhea. This medication should not be prescribed to patients with a sulfa allergy since it can cause anaphylaxis [10].
Before prescribing this medication, healthcare providers should also be aware of the precautions and contraindications. Healthcare providers should be cautious when prescribing this medication to patients with decreased kidney function, as it can lead to toxicity and high potassium levels. Therefore, baseline and frequent monitoring of blood urea nitrogen (BUN), creatinine, and potassium levels are helpful.
Other contraindications include patients with liver failure, hematological disorders, or who are pregnant. TMP-SMX interferes with several medications, including phenytoin, digoxin, diuretics, and rifampin. Many of these medication interactions increase the risk for potential hyperkalemia, medication toxicity, and QT prolongation [10].

Nitrofurantoin
Nitrofurantoin is another antibiotic commonly prescribed to treat urinary tract infections. This medication has been FDA-approved since 1953 to treat and prevent lower UTIs and is commonly considered a first-line treatment. Currently, nitrofurantoin has no other approved or off-label uses. It comes in two different forms, which are monohydrate and macrocrystalline [16].
The mechanism of action for nitrofurantoin is not completely understood. However, it is thought to be absorbed by bacterial flavoproteins in the gastrointestinal tract and then further prevents bacterial enzymes from synthesizing DNA, RNA, and cell wall proteins [16].
Nitrofurantoin is only available via the oral route. The dosage is usually 100 mg twice daily for UTI treatment and for UTI prophylaxis is 50mg to 100mg once daily. Common medication side effects include:
- Nausea and/or vomiting
- Diarrhea
- Loss of appetite [16]
Severe reactions, although rare, are pulmonary toxicity where patients may present with fever, chills, cough, and dyspnea. It may also cause liver toxicity, liver failure, and peripheral neuropathy. This medication is contraindicated in patients with a creatinine clearance of less than 60 mL/minute, hemolysis, or who have glucose-6-phosphate dehydrogenase (G6PD) deficiency [16].
Healthcare providers should also be aware of considerations when prescribing nitrofurantoin. They must understand that nitrofurantoin should not be prescribed to patients with suspected or confirmed pyelonephritis, since it is only used to treat lower UTIs.
Nitrofurantoin should not be prescribed to people who are pregnant, especially between 38 to 42 weeks gestation, and neonates. It is also not recommended to give to patients who are 65 years or older due to increased potential adverse effects. For patients who take nitrofurantoin long-term for prophylactic use, liver function tests should be routinely completed and monitoring of pulmonary function [16].

Fluoroquinolones
Fluoroquinolones are a class of antibiotics used to treat UTIs and other bacterial conditions. Examples of common fluoroquinolones include ciprofloxacin, moxifloxacin, and levofloxacin. However, ciprofloxacin is more commonly used to treat UTIs than the others and therefore, will be the medication reviewed in this section [19].
In addition to urinary tract infections, ciprofloxacin is FDA-approved to treat various health conditions. Some common health conditions treated are gonorrhea, chancroids, joint infections, prostatitis, and some gastrointestinal infections. Ophthalmic forms are used to treat corneal ulcers and conjunctivitis, while otic forms may be used in otitis externa [17].
Ciprofloxacin’s mechanism of action is considered bactericidal since it works by inhibiting bacterial DNA replication. It acts against DNA topoisomerase and DNA gyrase to hinder DNA replication. Ciprofloxacin is most effective against gram-negative bacteria, but also some gram-positive bacteria. Due to mutations in the DNA gyrase, ciprofloxacin and other fluoroquinolones have begun to show bacterial resistance over the past several years [17].
Ciprofloxacin comes in many forms, including oral, IV, ophthalmic, and otic. For the treatment of UTI, this medication is available via oral and IV forms. Recommended dosages are dependent on the severity of UTI and route. Oral dosages for UTI treatment range from 250mg to 500mg twice daily, while IV dosages can range from 200mg to 400mg twice daily to upwards of 400mg every eight hours. Regardless of the administration route, common side effects are nausea and diarrhea. Some serious adverse effects include:
- QT prolongation
- Hypoglycemia
- Hyperglycemia
- Photosensitivity [17]
Ciprofloxacin has an FDA black box warning of tendinitis and tendon rupture, peripheral neuropathy, and myasthenia gravis exacerbation. Due to the effects this medication has on tendons, Achilles tendon rupture, aortic aneurysm, and aortic dissection are also serious adverse effects. If the healthcare provider suspects any adverse effects, including mild tendonitis, the medication should be discontinued immediately.
Furthermore, when prescribing ciprofloxacin, there are additional considerations and contraindications. As with all medications, ciprofloxacin should not be prescribed to patients with a known allergy to this medication.
Ciprofloxacin should not be prescribed along with tizanidine, theophylline, or cyclosporine due to interactions. Antacids can also interfere with the absorption of ciprofloxacin and ciprofloxacin toxicity is more likely in older adults. Healthcare providers should encourage patients with diabetes to closely monitor their blood glucose levels at home since this medication can cause hypo- or hyperglycemia [17].

Beta-lactams
Beta-lactams are a class of antibiotics used to treat various bacterial conditions, including UTIs. The three main beta-lactams covered below are those commonly used to treat UTI and include cephalexin, amoxicillin-clavulanate, and ceftriaxone. Other beta-lactams that are approved for UTI treatment are cefpodoxime, cefdinir, and cefadroxil, and work similarly to others in this medication family.
Cephalexin
Cephalexin is a beta-lactam antibiotic that is classified as a first-generation cephalosporin. It was initially approved by the FDA in 1970 and is widely used throughout healthcare settings. In addition to acute and chronic UTIs, cephalexin is approved to treat upper and lower respiratory infections, bone infections, and otitis media. It is also used to treat surgical site, skin, and soft tissue infections [8].
Cephalexin falls under the beta-lactam class since its structure has a beta-lactam ring. This ring inhibits the synthesis of peptidoglycan which further disrupts the bacterial cell wall. More specifically, the beta-lactam ring binds to the penicillin-binding proteins during peptidoglycan synthesis, causing the disruption of the bacterial cell wall and viability [8].
Cephalexin is only available via oral route and can be prescribed in tablet, capsule, and suspension forms. Daily dosages from 1000mg to 4000mg for adults and for children, are weight-based and range from 25mg to 100mg per kilogram per day. Some side effects of cephalexin include:
- Abdominal pain
- Diarrhea
- Nausea and/or vomiting
- Rash
- Candidiasis [8]
Other reactions may include increased liver enzymes, C. diff colitis, and hemolytic anemia. Although cross-reactivity with penicillin is somewhat uncommon, healthcare providers should use caution when prescribing this medication to patients who are allergic to penicillin. Furthermore, it should not be prescribed to patients with a cephalosporin allergy. Cephalexin also interacts with metformin, causing decreased clearance of metformin from the body.
If a patient is taking metformin, they should be advised to closely monitor their blood glucose levels since the risk for hypoglycemia is increased. Healthcare providers should also be cautious when prescribing this medication to patients who are taking probenecid. Cephalexin can also increase prothrombin time, which typically requires monitoring, especially for those undergoing anticoagulant treatment [8].

Amoxicillin-clavulanate
As its name implies, amoxicillin-clavulanate is a combination medication of amoxicillin and clavulanic acid. In addition to treating UTIs, this medication is FDA-approved to treat rhinosinusitis, acute otitis media, skin infections, and aspiration and community-acquired pneumonia. Other non FDA-approved uses are impetigo, chronic obstructive pulmonary disease exacerbations, diabetic foot infections, and human and animal bites [4].
Amoxicillin-clavulanate works via two different mechanisms of action since it is a combination medication. The amoxicillin component is a beta-lactam antibiotic and works via the same mechanism as cephalexin described above. Clavulanic acid is a beta-lactamase inhibitor, which prevents bacteria from destroying beta-lactam antibiotics. Thus, the reason why clavulanic acid is often combined with amoxicillin [4].
This medication is only available via oral forms, such as suspensions, chewable, immediate-release, or extended-release tablets. Dosages are dependent on the underlying condition being treated, medication form (i.e. immediate- versus extended-release), and the patient’s age. Regardless of dosage, amoxicillin-clavulanate can lead to common gastrointestinal side effects, such as:
- Diarrhea
- Nausea
- Vomiting
- Loose stools [4]
Vaginal candidiasis is another common side effect of amoxicillin-clavulanate. For patients who are breastfeeding, this medication may cause hypersensitivity reactions in infants since it is excreted in breast milk. Additionally, amoxicillin-clavulanate has several drug interactions with medications, including probenecid, oral anticoagulants, allopurinol, and oral contraceptives. For patients on hemodialysis or with severe renal impairment, usually where their creatinine clearance is less than 30 mL/min, dose adjustments are recommended.
Healthcare providers should monitor patients’ liver enzymes for possible hepatic impairment, and if hepatic injury occurs, stop the medication immediately and follow treatment recommendations accordingly. Since amoxicillin is a penicillin derivative, it should not be prescribed to individuals with a penicillin allergy [4].

Ceftriaxone
Ceftriaxone is another beta-lactam antibiotic used to treat UTIs and is usually an adjunct medication. It is a third-generation cephalosporin that is also used to treat gonorrhea, pelvic inflammatory disease, meningitis, and certain abdominal, respiratory, and joint infections. Additionally, ceftriaxone treats bacteremia, sepsis, and infective endocarditis. Since ceftriaxone belongs to the beta-lactam class, its mechanism of action is the same as previously described cephalexin [18].
Ceftriaxone comes in both intravenous and intramuscular (IM) forms since it is not absorbed through the gastrointestinal tract. For UTI treatment, the dosage for adults is 1 to 2 grams IV or IM every 24 hours. In an outpatient setting, ceftriaxone is often given as a single IM dose to patients with pyelonephritis who are not hospitalized. Again, this medication is used as an adjunct medication, so it is given as a single IM dose, followed by another oral antibiotic for UTI treatment. Dosages for children range from 50mg to 75mg per kilogram per day for both IM and IV forms [18]. Some common side effects of ceftriaxone are:
- Diarrhea
- Nausea
- Vomiting
- Dysgeusia (metallic or foul taste in the mouth)
- Injection site reaction, especially for IM [18]
Other adverse effects associated with ceftriaxone are hemolytic anemias, neutropenia, and thrombocytosis. It should also be noted that this medication can cause neurological symptoms, cholelithiasis, jaundice, elevated liver enzymes, and pancreatitis [18].
Healthcare providers should also review ceftriaxone’s precautions and contraindications. This medication is cross-reactive with penicillin and can cause a hypersensitivity reaction. Furthermore, it should not be prescribed to patients with a cephalosporin allergy. If ceftriaxone is administered through an IV, it must not be mixed with calcium-containing IV solutions or products. Other possible medication interactions are estradiol, cyclosporine, and bumetanide. For patients with liver or kidney impairment, dosages must be adjusted and should not exceed 2 grams per day [18].

Cefdinir
Cefdinir is another beta-lactam antibiotic used to treat UTIs and is also a third-generation cephalosporin. In addition to UTI treatment, cefdinir is approved for the treatment of pneumonia, bacterial infections involving the skin, and respiratory infections of the ears, throat, and sinuses. As cefdinir is a third-generation cephalosporin, its mechanism of action is the same as previously described ceftriaxone. Thus, it interferes with bacterial cell wall synthesis [13].
Cefdinir is only available via oral route by either capsule or liquid suspension. Treatment dosages and duration are dependent on the underlying condition it is being used to treat [13]. For UTI, this medication is usually prescribed at 300mg twice daily for 5 to 7 days. However, this course may be extended for patients with pyelonephritis or complicated UTIs. Some common side effects of this medication include:
- Nausea and vomiting
- Diarrhea
- Vaginal itching
- Red-tinged stools [13]
Other more serious side effects may include rash, hives, facial swelling, and difficulty breathing or swallowing. As with all medications, healthcare providers should be aware of this medication’s precautions and contraindications. Cefdinir should not be prescribed to patients with a cephalosporin allergy or who are taking probenecid. It should also be avoided in patients with gastrointestinal diseases, like colitis, and kidney disease. This medication should be taken at least two hours apart from any aluminum, magnesium, or iron supplement. Additionally, healthcare providers should avoid prescribing the oral suspension form to patients with diabetes, since it contains high amounts of sucrose and can potentially raise blood sugar levels [13].

Other Antibiotics Used to Treat UTI
This section reviews other antibiotics used to treat urinary tract infections. Two common additional antibiotics administered in an inpatient setting include piperacillin-tazobactam and antipseudomonal carbapenems, such as imipenem or meropenem. These are usually reserved for patients with at least one risk factor for multidrug-resistant gram-negative organisms [7]. Drug information about meropenem will be discussed in greater detail below. Other less common antibiotics available in the outpatient are fosfomycin and pivmecillinam. Although these medicatios are used less commonly, it is still important to understand their pharmacokinetics.
Piperacillin-tazobactam
As mentioned, piperacillin-tazobactam is used to treat multidrug-resistant gram-negative UTIs in an inpatient setting. In addition to treating UTIs, it is approved for the treatment of skin, gynecological, and certain abdominal infections. This medication is a combination of piperacillin (a penicillin antibiotic) and tazobactam (a beta-lactamase inhibitor). Therefore, its mechanism of action is that of both the penicillin and beta-lactam classes as previously described [15].
Piperacillin-tazobactam is available in IV form and the dosage is usually 3.375 grams every six hours [7]. Like many antibiotics, some common side effects include:
- Diarrhea
- Nausea and/or vomiting
- Stomach pain [15]
This medication can also cause mouth sores, sleeping difficulties, and in more severe cases, itching, difficulty swallowing, and wheezing. Piperacillin-tazobactam should not be prescribed to patients who are taking other penicillin or beta-lactam antibiotics or who have an allergy. It interferes with certain medications including, aminoglycosides, anticoagulants, methotrexate, and vancomycin. Additionally, for patients with diabetes, this medication can cause false results with certain glucose tests [15].

Meropenem
An antipseudomonal carbapenem, meropenem, is used to treat inpatient multidrug-resistant gram-negative UTIs. Meropenem is also approved for the treatment of pneumonia, intra-abdominal infections, peritonitis, and meningitis [21].
This medication’s mechanism of action is similar to beta-lactams, as it falls under the same family of antibiotics. It binds to penicillin-binding proteins and inhibits bacterial cell wall synthesis by inhibiting peptidoglycan [21].
Meropenem is only available in IV form and dosages are dependent on the condition being treated. For UTIs, 1 gram is administered every 8 hours. Gastrointestinal side effects are common for this medication and include symptoms like diarrhea, nausea, vomiting, and constipation. Additional adverse effects may include:
- Drowsiness
- Headache
- Insomnia
- Depression [21]
Seizures are also a potential adverse effect, and therefore, healthcare providers must monitor patients for neurological symptoms. Agranulocytosis, thrombocytopenia, gastrointestinal bleeding, and hemolytic anemia are other conditions which have been reported when taking this medication. For patients with renal impairment, the dosage will need to be adjusted. Meropenem also has many medication interactions, with some major ones including afatinib, atogepant, cariprazine, and colchicine [21].

Fosfomycin
Fosfomycin is an antibiotic that is FDA-approved to treat uncomplicated urinary tract infections and is considered a first-line treatment option. In the United States, fosfomycin is only available in oral, powder which is mixed and dissolved in liquid. Furthermore, although this medication is a first-line UTI treatment option, it is not widely available in the United States [20].
This medication’s mechanism of action works by interfering with the formation of peptidoglycan precursor UDP N-acetylmuramic acid, also known as UDP-MurNAc. As it acts one step prior to the beta-lactam antibiotic family, Fosfomycin enters the bacteria through the transporter systems L-alpha-glycerophosphate and hexose-6-phosphate. This medication also reduces the ability of bacteria to adhere to the epithelial cells of the urinary tract [9].
To treat UTI, a single dose of 3 grams of fosfomycin is given, which is added to about 3 to 4 ounces of cold water to dissolve the medication. Common side effects may include:
- Nausea
- Diarrhea
- Headache
- Back pain [14]
Other serious side effects are joint pain, rash, facial or oral swelling, and jaundice. Healthcare providers should review this medication’s interactions and contraindications. Fosfomycin interacts with medications like cisapride, metoclopramide, and certain vitamins. Healthcare providers should use caution when prescribing to patients with a history of asthma, liver disease, or who are pregnant or breastfeeding [14].

Pivmecillinam
Pivmecillinam is another antibiotic used to treat lower urinary tract infections and is part of the UTI treatment algorithm. However, the FDA has not approved this medication for use in the United States [11]. Therefore, most of the specific drug information is not available.
Considerations for Prescribers
This section reviews potential considerations when prescribing antibiotics for UTIs.
Healthcare providers must consider and review several factors when prescribing antibiotics for UTI treatment. First, the medication’s route, dosage, and treatment duration are usually determined by the setting (inpatient versus outpatient), the type of UTI (e.g. empirical, asymptomatic bacteremia, uncomplicated, complicated, or prophylaxis), and the patient’s underlying medical conditions and risk factors. Furthermore, healthcare providers should strive to follow current treatment guidelines, approved uses, and their organization’s protocols when initiating or adjusting these medications. Healthcare providers must review the patient’s medical history, recent lab values, contraindications, and potential side effects.
Patient Population
Certain classes of antibiotics should be avoided in specific individuals or patient populations, and thus, healthcare providers must be aware of these precautions, contraindications, and black box warnings. Ciprofloxacin can lead to medication toxicity and hypoglycemia in older adults and must be avoided in this patient population when able [17]. Additionally, prescribing medications, such as TMP-SMZ and cephalexin, should be cautioned in patients with renal impairment [8, 10]. Prescribing nitrofurantoin, TMP-SMZ, cephalexin, and ceftriaxone should be cautioned in patients with liver failure or elevated liver enzymes. Healthcare providers should routinely monitor the patient’s liver enzymes and function tests [8, 10, 16, 18].
The patient’s gender at birth plays another large factor in antibiotic selection since treatment for males is considered a complicated UTI and antibiotic duration is extended. Furthermore, in patients who are pregnant or breastfeeding, certain antibiotics should not be prescribed, with some including TMP-SMZ and fluoroquinolones. Alternative treatments for patients who are pregnant are amoxicillin-clavulanate or [6]. For patients with chronic UTIs, initial prophylactic treatment should be started for 3 months and then reevaluated thereafter for prevention. Typical low-dose prophylactic antibiotics are TMP-SMX and nitrofurantoin. However, the healthcare provider should strongly consider medication compliance and potential antibiotic resistance [1].
Allergies
Healthcare providers should also review the patient’s allergies and cross-reactivity of certain antibiotics. Trimethoprim-sulfamethoxazole should not be prescribed to individuals with a sulfa allergy. Furthermore, healthcare providers should not prescribe patients with a penicillin allergy amoxicillin-clavulanate and should use caution when prescribing these individuals beta-lactams or cephalosporins due to their potential cross-reactivity, although the percentage is low [8, 10].
Medication History
As discussed, certain antibiotics interact with specific medications. Healthcare providers must review the patient’s medication list prior to prescribing antibiotics. For instance, amoxicillin-clavulanate interacts with allopurinol and lessens the effectiveness of oral contraceptives. Patients on oral contraceptives should be instructed to use backup birth control methods while on the antibiotic [4]. Additionally, while interactions may exist medication timing plays an important role. For example, medications such as ciprofloxacin and TMP-SMZ interact with antacids. However, if the antibiotic is taken two hours before or six hours after the antacid, a potential medication interaction is less likely [17]. Cephalexin is better absorbed on an empty stomach while other antibiotics are recommended to be taken with food [8].
Bacterial Sensitivity
Some antibiotics do not treat certain strains of bacteria and thus, healthcare providers must be judicious about initial antibiotic selection and following up with the patient about their urine culture results. For example, bacterial growth on the urine culture might not be sensitive to the initial antibiotic prescribed and may be resistant. Therefore, the antibiotic may need to be changed or dual therapy may be needed.
Also, patients with recurrent UTIs sometimes develop antibiotic resistance to first-line medications for the treatment of UTI, so an alternative medication should be initially prescribed, and a urine culture sent. If the patient is treated frequently for UTIs, then a referral to urology is warranted for further evaluation [6]. In some patients, asymptomatic bacteremia is found on a routine urinalysis completed during an annual comprehensive exam. Healthcare providers should review the current screening and treatment guidelines on asymptomatic bacteria in adults. For most patients, a urine culture should be sent for further evaluation, and antibiotic administration delayed until the culture has resulted [5].
Patient Education
Patients should be instructed on potential medication side effects and signs of adverse reactions. In an outpatient setting, healthcare providers must instruct patients on worsening symptoms and when to seek immediate or emergent treatment. Oftentimes, urinary tract infections move upstream into the kidneys and cause pyelonephritis or urosepsis [6].

Upcoming Research
This section reviews upcoming research and medications for UTI treatment.
The bacteria strain, E. coli, is typically responsible for urinary tract infections. However, this is not the case for all UTIs, and some patients have developed multiple drug-resistant organisms due to recurrent infections. Therefore, there is much research needed on UTI antibiotic treatment to eradicate these organisms. Recent development of immunomodulatory therapy has been considered as well as medications that inhibit bacterial adhesions to the epithelial cells of the urinary tract. Vaccinations against UTI have also shown recent promise, but further research is still needed [3]. Other non-antibiotic therapies are also being researched, like Lactobacillus-containing products (i.e. probiotics) and cranberry supplements [12].

Conclusion
As discussed, antibiotic selection for the treatment of urinary tract infections depends on a variety of factors. Healthcare providers should understand the pharmacokinetics, potential side effects, interactions, and contraindications when selecting an antibiotic. They should also follow current clinical guidelines and their facility’s protocols for a more evidence-based approach. Furthermore, ordering a urine culture or referring a patient to a urologist is warranted for patients with recurrent urinary tract infections.

Oral STI Medications
Introduction
When hearing the phrase sexually transmitted infections, what comes to mind? If you're an advanced practice registered nurse (APRN) with prescriptive authority, you've definitely heard of sexually transmitted infections (STIs) before. Even as a nurse or maybe before nursing school, conversations about prescription drug use and sexual health existed every so often.
Presently, patients seek guidance and information on various health topics from APRNs, including medication management and sexual health. The information in this course will serve as a valuable resource for APRNs with prescriptive authority of all specialties, education levels, and backgrounds to learn more about oral medications that can treat and manage STIs.
Defining Sexually Transmitted Infections (STIs)
What Are STIs?
Sexually transmitted infections (STIs) are infections that transmitted via sexual activity, such as oral sex, vaginal sex, anal sex, and sexual skin-to-skin contact. STIs can be bacterial, viral, and parasitic in nature and infect millions of people in the USA and around the world every year. STIs can be stigmatized as only common among those who are poor or unhoused, but it is important to note that anyone who is engaging in sexual activity is at risk for a STI (1).
What Are Bacterial STIs?
Bacterial STIs include chlamydia, gonorrhea, syphilis, bacterial vaginosis, chancroid, and mycoplasma genitalium.
Chlamydia is the most common bacterial STI in the United States and a leading cause of infection-related vision loss worldwide. Chlamydia is a bacterial infection as a result of exposure to the Chlamydia trachomatis bacterium via sexual contact.
Gonorrhea is another common bacterial STI in the United States and is a bacterial infection as a result of exposure to the Neisseria gonorrhoeae bacterium via sexual contact.
In addition, syphilis is another bacterial infection as a result of exposure to the spirochete Treponema pallidum bacteria via sexual contact (4). Syphilis rates in the United States were once very minimal but have increased significantly over the past few years (4).
Bacterial vaginosis is a vaginal condition in which there is an imbalance of bacteria in the vaginal microbiome (5). Several cases of bacterial vaginosis can be related to vaginal sexual activity; however, people can have bacterial vaginosis anytime there is an imbalance of bacteria in the vaginal microbiome (5).
Chancroid is a bacterial infection that is a result of exposure to the H. ducreyi bacterium via sexual contact (6). Chancroid prevalence in the United States has decreased over the past several years but is still a bacterial STI of concern (6).
The final bacterial STI for this course is mycoplasma genitalium, in which someone is exposed to this bacterium via sexual contact.
What Are Viral STIs?
Viral STIs include herpes simplex virus (HSV), human papillomavirus (HPV), and human immunodeficiency virus (HIV). HSV, also known as herpes, is a chronic viral infection that is transmitted via sexual skin-to-skin contact and sexual activity (8). HPV is the world's most common sexually transmitted infection, a chronic viral infection, and is transmitted via sexual skin-to-skin contact and sexual activity (9).
HIV is a chronic viral infection transmitted via blood, semen, vaginal secretion, or breastmilk that can progress to acquired immunodeficiency syndrome (AIDS) if left untreated and unmanaged (10).
What Are Parasitic STIs?
Trichomoniasis is a parasitic STI that is a result of being exposed to the Trichomonas vaginalis protozoan parasite via sexual activity (11).
What If STIs Are Left Untreated?
Depending on the STI, STIs can cause several long-term complications if left untreated. If HIV is not properly managed, several complications, such as AIDS and immune-related deficiencies, can emerge (10). Untreated or repeated chlamydia and gonorrhea infections can lead to chronic pelvic pain, genital pain, genital discharge, and infertility (2,3).
If syphilis is left untreated, neurological, cardiac, and musculoskeletal complications can occur (4). While the most common STI symptom is no symptom, it is important to offer routine STI screening and be able to assess and manage positive STI results if they occur.
Defining Oral STI Medications
Oral STI medications depend on the type of infection being treated or managed. Bacterial STIs are treated with antibiotics, and some viral STIs are managed with antiviral medications. The most common oral STI medications are azithromycin, metronidazole, acyclovir, and doxycycline.
Oral STI medications are used in various clinical settings, such as hospitals, outpatient clinical settings, public health departments, correction facilities, and more. Oral STI medications are prescribed and then taken by mouth. Depending on the dosage and type of STI, someone might take only one pill of an antibiotic to cure chlamydia or take a series of pills to manage their HIV viral load.
What are the Clinical Criteria for Prescribing Oral STI Medication?
Clinical criteria for prescribing oral STI medications can vary depending on the STI itself. First, a health care provider would order and perform testing to detect STIs, such as a Pap smear, urine sample, visual examination, blood sample, or genital swab (1,2,3,4,9).
If any of these tests show a positive result for an STI, clinical guidelines from reputable organizations, such as the Centers for Disease Control and Prevention (CDC) or the National Institutes of Health (NIH), are followed to manage these conditions (1, 2). In addition, local laws and health departments might have reporting requirements if a patient tests positive for an STI, so be sure to check with your local boards of nursing or health department on any reporting requirements.
What Is the Average Cost for Oral STI Medications?
Cost for oral STI medications can significantly vary depending on the type of medication, insurance, dosage, frequency, and other factors. Cost is among a leading reason why many patients cannot maintain their medication regime (12). If cost is a concern for your patient, consider reaching out to your local pharmacies or patient care teams to find cost effective solutions for your patients.

Antibiotic Pharmacokinetics
Drug Class – Oral Antibiotics for STIs
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient’s medication history and health history prior to prescribing oral medications for STIs.
Bacterial STIs include chlamydia, gonorrhea, syphilis, bacterial vaginosis, chancroid, and mycoplasma genitalium.
Oral Antibiotics Method of Action
The method of action for oral antibiotics for STI treatment depends on the antibiotic and the type of bacterium present.
Chlamydia infections are a result of exposure to the chlamydia trachomatis bacteria. A chlamydia infection can be treated with a course of doxycycline 100mg pills twice a day for seven days. Alternative treatment options include azithromycin 1 g pill as a single dose or levofloxacin 500mg pill once a day for seven days (1,2).
Doxycycline is an antibiotic that is part of the tetracycline drug class and works by preventing the growth of gram-negative and gram-positive bacteria, such as chlamydia trachomatis, Neisseria gonorrhoeae, and spirochete Treponema pallidum (13). Doxycycline works to eliminate the chlamydia trachomatis bacteria by binding to the 30S prokaryotic ribosomal unit during the protein synthesis, thus slowing down and eliminating the growth of bacteria (13).
Azithromycin and erythromycin are antibiotics that are part of the macrolide drug class and work by preventing the growth of many gram-negative and gram-positive bacteria (14). Azithromycin and erythromycin work to eliminate the chlamydia trachomatis bacteria and Hemophilus ducreyi by binding to the 50S subunit of bacterial ribosomes and leading to decreased bacterial synthesis (14).
Levofloxacin is an antibiotic that is part of the fluoroquinolone drug class and works by directly stopping bacterial DNA synthesis, as levofloxacin is considered to have the strongest activity against gram-positive, penicillin-sensitive, and resistant bacterium (15). Levofloxacin works to eliminate the chlamydia trachomatis bacteria by breaking the DNA strands through DNA-gyrase inhibition (15).
Gonorrhea infections are a result of exposure to the Neisseria gonorrhoeae bacteria. Gonorrhea infection treatment guidelines include a single injection of ceftriaxone depending on the patient’s weight (16). If ceftriaxone is a contraindication for the patient’s condition or unavailable, gonorrhea can be treated with a course of doxycycline 100mg pills twice a day for seven days (16).
Syphilis infection is a result of exposure to the spirochete Treponema pallidum bacteria (4). Syphilis infection treatment guidelines include benzathine penicillin injections, where the dosage and frequency depend on the stage of syphilis, patient age, and other co-existing health conditions. Some guidelines also recommend doxycycline 100mg pills twice a day for 14 days; however, penicillin injections appear to be more effective at syphilis management and treatment (4).
Bacterial vaginosis is not always STI, as bacterial vaginosis is the result of an imbalance of bacteria in the vaginal microbiome. However, regardless of the cause of bacterial vaginosis, current guidelines for bacterial vaginosis treatment includes metronidazole pills at 500mg twice a day for seven days with possible intravaginal application of metronidazole or clindamycin as well (5).
Metronidazole is a medication that is part of the nitroimidazole antimicrobial and antiprotozoal drug class, where its method of action involves protein synthesis inhibition (17). Metronidazole works to eliminate bacteria and Trichomonas vaginalis protozoan by causing the destruction of helical DNA structure and strand breakage, causing bacterial death (17). Tinidazole is another medication part of the nitroimidazole drug class, has a similar pharmacokinetic profile to metronidazole, and a higher cure rate for parasitic infections (17).
Chancroid is a result of exposure to the Haemophilus ducreyi (H. ducreyi) bacteria via sexual contact. Current guidelines for chancroid treatment include either a single dose of azithromycin 1g pill, a single ceftriaxone 250 mg injection, ciprofloxacin 500mg pills twice a day for three days, or erythromycin 500mg pills three times a day for seven days.
Ciprofloxacin is an antibiotic that is part of the fluoroquinolone drug class, where it works to eliminate the H. ducreyi bacteria by breaking the DNA strands through DNA-gyrase inhibition (18).
Having Mycoplasma Genitalium as an STI is a result of exposure to this bacterium. Current guidelines for mycoplasma Genitalium treatment depend on the macrolide sensitivity of the bacteria and patient condition. If the mycoplasma Genitalium is macrolide sensitive, the recommendations include doxycycline 100mg pills twice a day for 7 days followed by a single azithromycin 1mg pill, then followed by one 500mg pill once a day for three additional days (7). If the mycoplasma Genitalium is macrolide resistant or if resistance testing is not available, recommendations include doxycycline 100mg pills twice a day for 7 days followed by a single azithromycin 1mg pill, followed by moxifloxacin one 400 mg pill daily for seven days (7).
Trichomoniasis is a parasitic STI that is a result of being exposed to the Trichomonas vaginalis protozoan parasite via sexual activity (11). Current guidelines for trichomoniasis treatment include metronidazole one 500mg pill twice a day for 7 days for women or a single metronidazole 2g pill for men. An alternative treatment option for both men and women include a single tinidazole 2g pill (11).
Oral Antibiotic Side Effects
Every medication has the possibility of side effects, and oral antibiotics are no exception. Possible side effects of doxycycline include photosensitivity, GI upset, headaches, tooth discoloration, and a skin rash (13). More severe side effects of doxycycline include chest pain, leukopenia, changes in heart rate, and hepatoxicity.
Doxycycline is also contraindicated for pregnant people and children under 12 because of the teratogenic properties and risk of teeth discoloration. Doxycycline is also contraindicated for people who are allergic to tetracycline medications or penicillin (13).
Possible side effects of azithromycin and erythromycin include hepatotoxicity, GI upset, QT interval prolongation, and cardiac complications. Azithromycin and erythromycin are contraindicated in people who are allergic to macrolides (14).
Possible side effects of levofloxacin and moxifloxacin include photosensitivity, GI upset, headache, tendon rupture, changes in glucose levels, seizures, QT interval prolongation, and peripheral neuropathy. Levofloxacin and moxifloxacin are contraindicated in pregnancy and breastfeeding patients (15). Levofloxacin has FDA-issued box warnings for side effects related to tendinitis and tendon rupture, peripheral neuropathy, and central nervous system effects (15).
Possible side effects of metronidazole include peripheral neuropathy, metallic taste, GI upset, and confusion (17). Consuming alcohol and being in the first trimester of pregnancy are contraindications for metronidazole usage (17).
Possible side effects of ciprofloxacin include GI upset, QT interval prolongation, glucose level changes, and photosensitivity. FDA-issued box warnings for side effects related to ciprofloxacin include tendinitis and tendon rupture, peripheral neuropathy, and central nervous system effects (18).
Oral Antibiotics Alternatives
Given the nature of bacterial STIs, the only evidence-based method of treating bacterial STIs is with antibiotic medications (1). Condom use can help prevent the transmissions of STIs1.

Antiviral Pharmacokinetics
Drug Class – Oral Antivirals for STIs
Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing SSRIs.
Viral STIs include herpes simplex virus (HSV), human papillomavirus (HPV), and human immunodeficiency virus (HIV).
Oral Antivirals Method of Action
HSV, also known as herpes, is a chronic viral infection that is transmitted via sexual skin-to-skin contact and sexual activity (8). Current guidelines for HSV antiviral medication management include one acyclovir 400mg pill twice a day, one valacyclovir 500mg or 1g pill a day, or one famciclovir 250mg twice a day with a duration depending on the severity of the HSV outbreak, patient health history, and clinical presentation. Since HSV is a chronic viral health condition, dosage and frequency can vary from patient to patient.
Acyclovir and valacyclovir are an antiviral medication part of the antiviral drug class that works by incorporating into viral DNA, thus reducing further HSV synthesis (19). Valacyclovir is the prodrug to acyclovir (19). Famciclovir is a prodrug antiviral medication part of the nucleoside analog antiviral drug class, where its method of action involves inhibiting DNA polymerase, leading to decreased viral replication (20).
HPV is the world's most common sexually transmitted infection, a chronic viral infection, and is transmitted via sexual skin-to-skin contact and sexual activity (9). There are no oral STI medication options to manage HPV (9).
HIV is a chronic viral infection transmitted via blood, semen, vaginal secretion, or breastmilk that can progress to acquired immunodeficiency syndrome (AIDS) if left untreated and unmanaged (10). Given the complex pharmacological properties of HIV antiviral medications and HIV clinical manifestations, refer to specialty care for HIV for chronic management or seek additional training if possible (10).
There are several antiviral medications that can be used to manage HIV depending on the patient's health history, severity of HIV status, and clinical presentation. Oral antiviral drug classes for HIV medications include capsid inhibitors, entry inhibitors, nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), integrase strand transfer inhibitors (ISTIs), and protease inhibitors (PIs) (10).
Lenacapavir is a capsid inhibitor often prescribed at 600 mg once a day that works to distort HIV capsid protein function, thus reducing the influence of HIV in the body. Similar to HSV medications, dosage, frequency, and co-administration of other HIV-related antivirals will depend on patient response to the medication, patient health history, and patient condition (10).
Entry inhibitors work to reduce the HIV viral load by blocking HIV from entering CD4 cells. There are three main types of entry inhibitors: CCR5 antagonists, fusion inhibitors, and attachment inhibitors.
Maraviroc is an entry inhibitor pill often prescribed at 150, 300, or 600 mg, depending on patient health history and severity of HIV. Maraviroc acts as a CCR5 antagonist, where the method of action is blocking HIV from binding to the chemokine coreceptor 5 (CCR5) (10).
Enfuvirtide is an injection medication and acts as an entry inhibitor by preventing HIV from fusing to CD4 cells walls. Fostemsavir is another entry inhibitor pill often prescribed at 600mg twice daily, where the method of action is binding to the HIV glycoprotein GP120 to inhibit HIV attachment to host T cells (10).
NRTIs include abacavir, emtricitabine, lamivudine, tenofovir alafenamide, tenofovir disoproxil fumarate, zidovudine, didanosine, and stavudine. NRTIs are often given in pairs, where the most commonly prescribed pairs are tenofovir alafenamide-emtricitabine, tenofovir disoproxil fumarate-emtricitabine, and abacavir-lamivudine. Clinical management of HIV with NRTIs can depend on severity of HIV, co-existing health conditions, and patient health history. NRTIs' method of action involves undergoing intracellular phosphorylation mediated by host enzymes, allowing HIV's DNA chains to be depleted over time (10).
NNRTIs work to suppress the HIV viral load by preventing HIV-1 reverse transcriptase from creating new nucleotides to the HIV DNA chain. Common NNRTI medications include efavirenz, nevirapine, doravirine, etavirine, and rilpivirine (10).
INSTIs work to suppress the HIV viral load by targeting the strand transfer step of HIV DNA replication, thus reducing the rate in which the HIV DNA replicates. Common INSTI medications include raltegravir, elvitegravir, dolutegravir, and bictregravir (10).
Protease inhibitors work to suppress the HIV viral load by suppressing the cleaving of Gag-Pol polyproteins in HIV-infected cells, thus having cells that are not mature enough to be infectious in the body. Protease inhibitors include atazanavir, darunavir, lopinavir, indinavir, fosamprenavir, nelfinavir, saquinavir, and tipranavir (10).
Oral Antiviral Side Effects
Every medication has the possibility of side effects, and oral antivirals are no exception.
- The most common side effects of acyclovir and valacyclovir include fatigue, GI upset, confusion, headache, and neurotoxicity (19). Most common side effects of famciclovir include GI upset, headache, and hepatoxicity (20).
- Common side effects of lenacapavir include GI upset, changes in blood sugar, changes in urine, and hepatic dysfunction (10).
- Side effects commonly noted in maraviroc include skin rash, GI upset, sexual dysfunction, and anemia. There is an FDA boxed warning for maraviroc and hepatoxicity (10).
- The most common side effects of fostemsavir include increased serum creatine, prolonged QT elongation, changes in cholesterol levels, changes in glucose levels, changes in liver, and confusion (10).
- Common side effects of NRTIs include mitochondrial toxicity, which can have a significant range of clinical presentations, such as hepatic dysfunction, peripheral neuropathy, changes in cholesterol levels, or changes in pancreatic function. Zidovudine, in particular, has an FDA boxed warning for hematological toxicity, myopathy, and severe hepatomegaly (10).
- Common side effects of NNRTIs include GI upset, headache, skin rash, changes in cholesterol levels, and changes in glucose levels. The most commonly prescribed NNRTIs rilpivirine and etavirine have possible side effects of prolonged QT interval and neuropsychological effects (10).
- Side effects commonly reported with INSTIs include changes in weight, headache, and GI upset. Dolutegravir and raltegravir in particular have possible side effects of myopathy, elevations in creatine phosphokinase (CPK), and rhabdomyolysis (10).
- Common side effects of protesase inhibitors include changes in blood glucose, changes in cholesterol levels, hepatotoxicity, PR interval prolongation, GI upset, and headache (10).
Oral Antiviral Alternatives
HIV and HSV are complex, chronic conditions that are often managed with antiviral medications and require patient monitoring to observe patient response to the medications and clinical presentation.
While antiviral medications are considered the standard for evidence-based care for HSV and HIV, lifestyle modifications to strengthen one's immune system, such as increased sleep, decreased stress, and a healthy diet are thought to play a role in HIV and HSV management (10). Condom use can help prevent the transmissions of STIs (1).

Nursing Considerations
Nurses remain the most trusted profession for a reason, and APRNs are often pillars of patient care in several health care settings. Patients turn to nurses for guidance, education, and support.
While there is no specific guideline for the nurses' role in STI education and management, here are some suggestions to provide quality care for patients currently taking oral medications to manage STIs or concerned about possibly having a STI.
- Take a detailed health history. Often times, sexual health, such as pain during sex or bleeding after sex, are often dismissed in health care settings. If a patient is complaining of symptoms that could be related to a STI, inquire more about that complaint.
Ask about how long the symptoms have lasted, what treatments have been tried, if these symptoms interfere with their quality of life, and if anything alleviates any of these symptoms. If you feel like a patient's complaint is not being taken seriously by other health care professionals, advocate for that patient to the best of your abilities.
- Review medication history at every encounter. Often times, in busy clinical settings, reviewing health records can be overwhelming. Millions of people take antibiotics and antiviral medications for various infections. Ask patients how they are feeling on the medication, if their symptoms are improving, and if there are any changes to medication history.
- Be willing to answer questions about sexual health and oral STI medication options. Society stigmatizes open discussions of prescription medication and sexual health. There are many people who do not know about safe sexual practices, the long-term effects of undiagnosed or repeat STIs, or possible STI treatment options.
Be willing to be honest with yourself about your comfort level discussing topics and providing education on oral STI medications and STI prevention.
- Communicate the care plan to other staff involved for continuity of care. For several patients, especially for patients with viral STI infections or re-current STIs, care often involves a team of mental health professionals, nurses, specialists, pharmacies, and more. Ensure that patients' records are up to date for ease in record sharing and continuity of care.
- Stay up to date on continuing education related to oral STI medications and STIS. This is essential, as evidence-based information is always evolving and changing. You can then present your new learnings and findings to other health care professionals and educate your patients with the latest information.
You can learn more about the latest research on oral STI medications and STIs by following updates from evidence-based organizations.
How can nurses identify if someone has a STI?
Unfortunately, it is not possible to look at someone with the naked eye and determine if they have an STI. While some people might have visible STI symptoms, such as a wart or discharge, the most common STI symptom is no symptom.
APRNs can identify and diagnose if someone has a STI by taking a complete health history, listening to patient's concerns, and offering STI testing.
What should patients know about oral STI medication?
Patients should know that anyone has the possibility of experiencing side effects on antiviral or antibiotic medications for STIs, just like any other medication. Patients should be aware that if they notice any changes in their vision, experience any sharp headaches, or feel like something is a concern, they should seek medical care.
Because of social stigma associated with sexual health, people are hesitant to seek medical care because of fear, shame, and embarrassment. However, as more research and social movements discuss sexual health more openly, there is more space and awareness for STI prevention and management.
Nurses should also teach patients to advocate for their own health in order to avoid untreated or undetected STIs and possible unwanted side effects of oral STI medication.
Here are important tips for patient education in the inpatient or outpatient setting:
- Tell the health care provider of any existing medical conditions or concerns (need to identify risk factors)
- Tell the health care provider of any existing lifestyle concerns, such as alcohol use, other drug use, sleeping habits, diet, menstrual cycle changes (need to identify lifestyle factors that can influence SSRI use and major depressive disorder management)
- Tell the health care provider if you have any changes in your pelvis, such as pain with urination, pain during sex, or bleeding during or after sex (potential STI symptoms)
- Tell the nurse of health care provider if you experience any pain that increasingly becomes more severe or interferes with your quality of life
- Keep track of your sexual health, medication use, and health concerns via an app, diary, or journal (self-monitoring for any changes)
- Tell the health care provider right away if you are having thoughts of hurting yourself or others (possible increased risk of suicidality is a possible side effect for ____ use)
- Take all prescribed medications as indicated and ask questions about medications and possible other treatment options, such as non-pharmacological options or surgeries
- Tell the health care provider if you notice any changes while taking medications or on other treatments to manage STIs (potential worsening or improving health situation)

Conclusion
STIs affect millions of people nationwide and can affect anyone who is having sex. Oral STI medication is often a first-line pharmacological option for managing several STIs. However, clinical presentation and symptom management for STIs can vary widely. Education and awareness of different STIs and different oral STI medications can influence the lives of many people in a healthy way.

Introduction
Pain is complex and subjective. The experience of pain can significantly impact an individual’s quality of life. According to the National Institute of Health (NIH) (40), pain is the most common complaint in a primary care office, with 20% of all patients reporting pain. Chronic pain is the leading cause of disability, and effective pain management is crucial to health and well-being, particularly when it improves functional ability. Effective pain treatment starts with a comprehensive, empathic assessment and a desire to listen and understand. Nurse Practitioners are well-positioned to fill a vital role in providing comprehensive and empathic patient care, including pain management (23).
While the incidence of chronic pain has remained a significant problem, how clinicians manage pain has significantly changed in the last decade, primarily due to the opioid epidemic. This education aims to discuss pain and the assessment of pain, federal guidelines for prescribing, the opioid epidemic, addiction and diversion, and recommendations for managing pain.
Definition of Pain
Understanding the definition of pain, differentiating between various types of pain, and recognizing the descriptors patients use to communicate their pain experiences are essential for Nurse practitioners involved in pain management. By understanding the medical definition of pain and how individuals may communicate it, nurse practitioners can differentiate varying types of pain to target assessment.
According to the International Association for the Study of Pain (27), pain is “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or terms of described such in damage.” The IASP, in July 2020, expanded its definition of pain to include context further.
Their expansion is summarized below:
- Pain is a personal experience influenced by biological, psychological, and social factors.
- Pain cannot be inferred solely from activity in sensory neurons.
- Individuals learn the concept of pain through their life experiences.
- A person’s report of an experience in pain should be respected.
- Pain usually serves an adaptive role but may adversely affect function and social and psychological well-being.
- The inability to communicate does not negate the possibility of the experience of pain.

Types of Pain
Pain originates from different mechanisms, causes, and areas of the body. As a nurse practitioner, understanding the type of pain a patient is experiencing is essential for several reasons (23).
- Determining an accurate diagnosis. This kind of pain can provide valuable clues to the underlying cause or condition.
- Creating a treatment plan. Different types of pain respond better to specific treatments or interventions.
- Developing patient education. A nurse practitioner can provide targeted education to patients about their condition, why they may experience the pain as they do, its causes, and treatment options. Improving the patient's knowledge and control over their condition improves outcomes.
Acute Pain
Acute pain is typically short-lived and is a protective response to an injury or illness. Patients are usually able to identify the cause. This type of pain resolves as the underlying condition improves or heals (12).
Chronic Pain
Chronic pain is diagnosed when it continues beyond the expected healing time. Pain is defined as chronic when it persists for longer than three months. It may result from an underlying disease or injury or develop without a clear cause. Chronic pain often significantly impacts a person's physical and emotional well-being, requiring long-term management strategies. The prolonged experience of chronic pain usually indicates a central nervous system component of pain that may require additional treatment. Patients with centralized pain often experience allodynia or hyperalgesia (12).
Allodynia is pain evoked by a stimulus that usually does not cause pain, such as a light touch. Hyperalgesia is the effect of a heightened pain response to a stimulus that usually evokes pain (12).
Nociceptive Pain
Nociceptive pain arises from activating peripheral nociceptors, specialized nerve endings that respond to noxious stimuli. This type of pain is typically associated with tissue damage or inflammation and is further classified into somatic and visceral pain subtypes.
Somatic pain is most common and occurs in muscles, skin, or bones; patients may describe it as sharp, aching, stiffness, or throbbing.
Visceral pain occurs in the internal organs, such as indigestion or bowel spasms. It is more vague than somatic pain; patients may describe it as deep, gnawing, twisting, or dull (12).
Neuropathic pain
Neuropathic pain is a lesion or disease of the somatosensory nervous system. Examples include trigeminal neuralgia, painful polyneuropathy, postherpetic neuralgia, and central poststroke pain (10).
Neuropathic pain may be ongoing, intermittent, or spontaneous pain. Patients often describe neuropathic pain as burning, prickling, or squeezing quality. Neuropathic pain is a common chronic pain. Patients commonly describe allodynia and hyperalgesia as part of their chronic pain experience (10).
Affective pain
Affective descriptors reflect the emotional aspects of pain and include terms like distressing, unbearable, depressing, or frightening. These descriptors provide insights into the emotional impact of pain on an individual's well-being (12).

Case Study
Mary Adams is a licensed practical nurse who has just relocated to town. Mary will be the utilization review nurse at a local long-term care facility. Mary was diagnosed with Postherpetic Neuralgia last year, and she is happy that her new job will have her mostly doing desk work and not providing direct patient care as she had been before the relocation. Mary was having difficulty at work at her previous employer due to pain. She called into work several times, and before leaving, Mary's supervisor had counseled her because of her absences.
Mary wants to establish primary care immediately because she needs ongoing pain treatment. She is hopeful that, with her new job and pain under control, she will be able to continue a successful career in nursing. When Mary called the primary care office, she specifically requested a nurse practitioner as her primary care provider because she believes that nurse practitioners tend to spend more time with their patients.
Assessment
The assessment effectively determines the type of treatment needed, the options for treatment, and whether the patient may be at risk for opioid dependence. Since we know that chronic pain can lead to disability and pain has a high potential to negatively affect the patient's ability to work or otherwise, be productive, perform self-care, and potentially impact family or caregivers, it is imperative to approach the assessment with curiosity and empathy. This approach will ensure a thorough review of pain and research on pain management options. Compassion and support alone can improve patient outcomes related to pain management (23).
Record Review
Regardless of familiarity with the patient, reviewing the patient's treatment records is essential, as the ability to recall details is unreliable. Reviewing the records can help identify subtle changes in pain description and site, the patient's story around pain, failed modalities, side effects, and the need for education, all impacting further treatment (23).
Research beforehand the patient's current prescription and whether or not the patient has achieved the maximum dosage of the medication. Analysis of the patient's past prescription could reveal a documented failed therapy even though the patient did not receive the maximum dose (23).
A review of documented allergens may indicate an allergy to pain medication. Discuss with the patient the specific response to the drug to determine if it is a true allergy, such as hives or anaphylaxis, or if the response may have been a side effect, such as nausea and vomiting.
Research whether the patient tried any non-medication modalities for pain, such as physical therapy (PT), occupational therapy (OT), or Cognitive Behavioral Therapy (CBT). Note any non-medication modalities documented as failed therapies. The presence of any failed therapies should prompt further discussion with the patient, family, or caregiver about the experience. The incompletion of therapy should not be considered failed therapy. Explore further if the patient abandoned appointments.
Case Study
You review the schedule for the week, and there are three new patient appointments. One is Mary Adams. The interdisciplinary team requested and received Mary's treatment records from her previous primary care provider. You make 15 minutes available to review Mary's records and the questionnaire Mary filled out for her upcoming appointment. You see that Mary has been diagnosed with Postherpetic Neuralgia and note her current treatment regimen, which she stated was ineffective. You write down questions you will want to ask Mary. You do not see evidence of non-medication modalities or allergies to pain medication.

Pain Assessment
To physically assess pain, several acronyms help explore all the aspects of the patient's experience. Acronyms commonly used to assess pain are SOCRATES, OLDCARTS, and COLDERAS. These pain assessment acronyms are also helpful in determining treatment since they include a character and duration of pain assessment (23).
O-Onset | S-Site | C-Character |
L-Location | O-Onset | O-Onset |
D-Duration | C-Character | L-Location |
C-Character | R-Radiate | D-Duration |
A-Alleviating | A-Associated symptoms | E-Exacerbating symptoms |
R-Radiating, relieving | T-Time/Duration | R-Relieving, radiating |
T-Temporal patterns (frequency) | E-Exacerbating | A-Associated symptoms |
S-Symptoms | S-Severity | S-Severity of illness |
Inquire where the patient is feeling pain. The patient may have multiple areas and types of pain. Each type and location must be explored and assessed. Unless the pain is from a localized injury, a body diagram map, as seen below, is helpful to document, inform, and communicate locations and types of pain. In cases of Fibromyalgia, rheumatoid arthritis, or other centralized or widespread pain, it is vital to inquire about radiating pain. The patient with chronic pain could be experiencing acute pain or a new pain site, such as osteoarthritis, that may need further evaluation and treatment (23).
Inquire with the patient how long their pain has been present and any associated or known causative factors. Pain experienced longer than three months defines chronic versus acute pain. Chronic pain means that the pain is centralized or a function of the Central Nervous system, which should guide treatment decisions.
To help guide treatment, ask the patient to describe their pain. The description helps identify what type of pain the patient is experiencing: Allodynia and hyperalgesia indicate centralized pain; sharp, shooting pain could indicate neuropathic pain. Have the patient rate their pain. There are various tools, as shown below, for pain rating depending on the patient's ability to communicate. Not using the pain rating number alone is imperative. Ask the patient to compare the severity of pain to a previous experience. For example, a 1/10 may be experienced as a bumped knee or bruise, whereas a 10/10 is experienced on the level of a kidney stone or childbirth (23).
Besides the 0-10 rating scale and depending on the patient's needs, several pain rating scales are appropriate. They are listed below.
The 0-5 and Faces scales may be used for all adult patients and are especially effective for patients experiencing confusion.
The Defense and Veterans Pain Rating Scale (DVPRS) is a five-item tool that assesses the impact of pain on sleep, mood, stress, and activity levels (20).
For patients unable to self-report pain, such as those intubated in the ICU or late-stage neurological diseases, the FLACC scale is practical. The FLACC scale was initially created to assess pain in infants. Note: The patient need not cry to be rated 10/10.
Behavior | 0 | 1 | 2 |
Face | No particular expression or smile | Occasional grimace or frown, withdrawn, disinterested | Frequent or constant quivering chin, clenched jaw |
Legs | Normal position or relaxed | Uneasy, restless, tense | Kicking or legs drawn |
Activity | Lying quietly, in a normal position, or relaxed | Squirming, shifting back and forth, tense | Arched, rigid, or jerking |
Cry | No cry wake or asleep | Moans or whimpers: occasional complaints | Crying steadily, screams, sobs, frequent complaints |
Consolability | Content, relaxed | Distractable, reassured by touching, hugging, or being talked to | Difficult to console or comfort |
(21).
Assess contributors to pain such as insomnia, stress, exercise, diet, and any comorbid conditions. Limited access to care, socioeconomic status, and local culture also contribute to the patient's experience of pain (23). Most patients have limited opportunity to discuss these issues, and though challenging to bring up, it is compassionate and supportive care. A referral to social work or another agency may be helpful if you cannot explore it fully.
Assess for substance abuse disorders, especially among male, younger, less educated, or unemployed adults. Substance abuse disorders increase the likelihood of misuse disorder and include alcohol, tobacco, cannabis, cocaine, and heroin (29).
Inquire as to what changes in function the pain has caused. One question to ask is, "Were it not for pain, what would you be doing?" As seen below, a Pain, Enjoyment, and General Activity (PEG) three-question scale, which focuses on function and quality of life, may help determine the severity of pain and the effect of treatment over time.
What number best describes your pain on average in the past week? 0-10 |
What number best describes how, in the past week, pain has interfered with your enjoyment of life? 0-10 |
What number determines how, in the past week, pain has interfered with your general activity? 0-10 |
(21).
Assess family history, mental health disorders, chronic pain, or substance abuse disorders. Each familial aspect puts patients at higher risk for developing chronic pain (23).
Evaluate for mental health disorders the patient may be experiencing, particularly anxiety and depression. The Patient Health Questionnaire (PHQ4) is a four-question tool for assessing depression and anxiety.
In some cases, functional MRI or imaging studies effectively determine the cause of pain and the treatment. If further assessment is needed to diagnose and treat pain, consult Neurology, Orthopedics, Palliative care, and pain specialists (23).
Case Study
You used OLDCARTS to evaluate Mary's pain and completed a body diagram. Mary is experiencing allodynia in her back and shoulders, described as burning and tingling. It is exacerbated when she lifts, such as moving patients at the long-term care facility and, more recently, boxes from her move to the new house. Mary has also been experiencing anxiety due to fear of losing her job, the move, and her new role. She has moved closer to her family to help care for her children since she often experiences fatigue. Mary has experienced a tumultuous divorce in the last five years and feels she is still undergoing some trauma.
You saw in the chart that Mary had tried Gabapentin 300 mg BID for her pain and inquired what happened. Mary explained that her pain improved from 8/10 to 7/10 and had no side effects. Her previous care provider discontinued the medication and documented it as a failed therapy. You reviewed the minimum and maximum dosages of Gabapentin and know Mary can take up to 1800mg/day.
During the assessment, Mary also described stiffness and aching in her left knee. She gets a sharp pain when she walks more than 500 steps, and her knee is throbbing by the end of the day. Mary rated the pain a 10/10, but when she compared 10/10 to childbirth, Mary said her pain was closer to 6/10. Her moderate knee pain has reduced Mary's ability to exercise. She used to like to take walks. Mary stated she has had knee pain for six months and has been taking Ibuprofen 3 – 4 times daily.
Since Mary's pain is moderate, you evaluate your options of drugs for moderate to severe pain.

Opioid Classifications and Drug Schedules
A comprehensive understanding of drug schedules and opioid classifications is essential for nurse practitioners to ensure patient safety, prevent drug misuse, and adhere to legal and regulatory requirements. Nurse practitioners with a comprehensive understanding of drug schedules and opioid classifications can effectively communicate with colleagues, ensuring accurate medication reconciliation and facilitating interdisciplinary care. Nurse practitioners’ knowledge in facilitating discussions with pharmacists regarding opioid dosing, potential interactions, and patient education is essential (49).
Drug scheduling became mandated under the Controlled Substance Act. The Drug Enforcement Agency (DEA) Schedule of Controlled Drugs and the criteria and common drugs are listed below.

Commonly Prescribed Opioids, Indications for Use, and Typical Side Effects
Opioid medications are widely used for managing moderate to severe pain. Referencing NIDA (2023), this section aims to give healthcare professionals an overview of the indications and typical side effects of commonly prescribed Schedule II opioid medications, including hydrocodone, oxycodone, morphine, Fentanyl, and hydromorphone.
Opioids are derived and manufactured in several ways. Naturally occurring opioids come directly from the opium poppy plant. Synthetic opioids are manufactured by chemically synthesizing compounds that mimic the effects of a natural opioid. Semi-synthetic is a mix of naturally occurring and man-made (35).
Understanding the variations in how an opioid is derived and manufactured is crucial in deciding the type of opioid prescribed, as potency and analgesic effects differ. Synthetic opioids are often more potent than naturally occurring opioids. Synthetic opioids have a longer half-life and slower elimination, affecting the duration of action and timing for dose adjustments. They are also associated with a higher risk of abuse and addiction (38).
Hydrocodone
Mechanism of Action and Metabolism
Hydrocodone is a Schedule II medication. It is an opioid agonist and works as an analgesic by activating mu and kappa opioid receptors located in the central nervous system and the enteric plexus of the bowel. Agonist stimulation of the opioid receptors inhibits nociceptive neurotransmitters' release and reduces neuronal excitability (17).
- Produces analgesia.
- Suppresses the cough reflex at the medulla.
- Causes respiratory depression at higher doses.
Hydrocodone is indicated for treating severe pain after nonopioid therapy has failed. It is also indicated as an antitussive for nonproductive cough in adults over 18.
Available Forms
Hydrocodone immediate release (IR) reaches maximum serum concentrations in one hour with a half-life of 4 hours. Extended-release (ER) Hydrocodone reaches peak concentration at 14-16 hours and a half-life of 7 to 9 hours. Hydrocodone is metabolized to an inactive metabolite in the liver by cytochrome P450 enzymes CYP2D6 and CYP3A4. Hydrocodone is converted to hydromorphone and is excreted renally. Plasma concentrations of hydromorphone are correlated with analgesic effects rather than hydrocodone.
Hydrocodone is formulated for oral administration into tablets, capsules, and oral solutions. Capsules and tablets should never be crushed, chewed, or dissolved. These actions convert the extended-release dose into immediate release, resulting in uncontrolled and rapid release of opioids and possible overdose.
Dosing and Monitoring
Hydrocodone IR is combined with acetaminophen or ibuprofen. The dosage range is 2.5mg to 10mg every 4 to 6 hours. If formulated with acetaminophen, the dosage is limited to 4gm/day.
Hydrocodone ER is available as tablets and capsules. Depending on the product, the dose of hydrocodone ER formulations in opioid-naïve patients is 10 to 20 mg every 12 to 24 hours.
Nurse practitioners should ensure patients discontinue all other opioids when starting the extended-release formula.
Side Effects and Contraindications
Because mu and kappa opioid receptors are in the central nervous system and enteric plexus of the bowel, the most common side effects of hydrocodone are constipation and nausea (>10%).
Other adverse effects of hydrocodone include:
- Respiratory: severe respiratory depression, shortness of breath
- Cardiovascular: hypotension, bradycardia, peripheral edema
- Neurologic: Headache, chills, anxiety, sedation, insomnia, dizziness, drowsiness, fatigue
- Dermatologic: Pruritus, diaphoresis, rash
- Gastrointestinal: Vomiting, dyspepsia, gastroenteritis, abdominal pain
- Genitourinary: Urinary tract infection, urinary retention
- Otic: Tinnitus, sensorineural hearing loss
- Endocrine: Secondary adrenal insufficiency (17)
Hydrocodone, being an agonist, must not be taken with other central nervous system depressants as sedation and respiratory depression can result. In formulations combined with acetaminophen, hydrocodone can increase the international normalized ratio (INR) and cause bleeding. Medications that induce or inhibit cytochrome enzymes can lead to wide variations in absorption.
The most common drug interactions are listed below:
- Alcohol
- Benzodiazepines
- Barbiturates
- other opioids
- rifampin
- phenytoin
- carbamazepine
- cimetidine,
- fluoxetine
- ritonavir
- erythromycin
- diltiazem
- ketoconazole
- verapamil
- Phenytoin
- John’s Wort
- Glucocorticoids
Considerations
Use with caution in the following:
- Patients with Hepatic Impairment: Initiate 50% of the usual dose
- Patients with Renal Impairment: Initiate 50% of the usual dose
- Pregnancy: While not contraindicated, the FDA issued a black-boxed warning since opioids cross the placenta, and prolonged use during pregnancy may cause neonatal opioid withdrawal syndrome (NOWS).
- Breastfeeding: Infants are susceptible to low dosages of opioids. Non-opioid analgesics are preferred.
Pharmacogenomic: Genetic variants in hydrocodone metabolism include ultra-rapid, extensive, and poor metabolizer phenotypes. After administration of hydrocodone, hydromorphone levels in rapid metabolizers are significantly higher than in poor metabolizers.
Oxycodone
Mechanism of Action and Metabolism
Oxycodone has been in use since 1917 and is derived from Thebaine. It is a semi-synthetic opioid analgesic that works by binding to mu-opioid receptors in the central nervous system. It primarily acts as an agonist, producing analgesic effects by inhibiting the transmission of pain signals (Altman, Clark, Huddart, & Klein, 2018).
Oxycodone is primarily metabolized in the liver by CYP3A4/5. It is metabolized in the liver to noroxycodone and oxymorphone. The metabolite oxymorphone also has an analgesic effect and does not inhibit CYP3A4/5. Because of this metabolite, oxycodone is more potent than morphine, with fewer side effects and less drug interactions. Approximately 72% of oxycodone is excreted in urine (Altman, Clark, Huddart, & Klein, 2018).
Available Forms
Oxycodone can be administered orally, rectally, intravenously, and as an epidural. For this sake, we will focus on immediate-release and extended-release oral formulations.
- Immediate-release (IR) tablets
- IR capsules
- IR oral solutions
- Extended-release (ER) tablets
Dosing and Monitoring
The dosing of oxycodone should be individualized based on the patient's pain severity, previous opioid exposure, and response. Initial dosages for opioid naïve patients range from 5-15 mg for immediate-release formulations, while extended-release formulations are usually initiated at 10-20 mg. Dosage adjustments may be necessary based on the patient's response, but caution should be exercised. IR and ER formulations reach a steady state at 24 hours and titrating before 24 hours may lead to overdose.
Regular monitoring is essential to assess the patient's response to treatment, including pain relief, side effects, and signs of opioid misuse or addiction. Monitoring should include periodic reassessment of pain intensity, functional status, and adverse effects (Altman, Clark, Huddart, & Klein, 2018).
Side Effects and Contraindications
Common side effects of oxycodone include:
- constipation
- nausea
- sedation
- dizziness
- respiratory depression
- respiratory arrest
- hypotension
- fatal overdose
Oxycodone is contraindicated in patients with known hypersensitivity to opioids, severe respiratory depression, paralytic ileus, or acute or severe bronchial asthma. It should be used cautiously in patients with a history of substance abuse, respiratory conditions, liver or kidney impairment, and those taking other medications that may interact with opioids, such as alcohol (4).
It is also contraindicated with the following medications and classes:
- Antifungal agents
- Antibiotics
- Rifampin
- Carbamazepine
- Fluoxetine
- Paroxetine
Considerations
- Nurse practitioners should consider the variations in the mechanism of action for the following:
- Metabolism differs between males and females: females have been shown to have less concentration of oxymorphone and more CYP3A4/5 metabolites.
- Infants have reduced clearance of oxycodone, increasing side effects.
- Pediatrics have 20-40% increased clearance over adults.
- Reduced clearance with age increases the half-life of oxycodone.
- Pregnant women have a greater clearance and reduced half-life.
- Impairment of the liver reduces clearance.
- Cancer patients with cachexia have increased exposure to oxycodone and its metabolite.
- Maternal and neonate concentrations are similar, indicating placenta crossing (4)
Morphine
Mechanism of Action and Metabolism
Morphine is a naturally occurring opioid alkaloid extracted from the opium poppy. It was isolated in 1805 and is the opioid against which all others are compared. Morphine binds to mu-opioid receptors in the brain and spinal cord, inhibiting the transmission of pain signals and producing analgesia. It is a first-line choice of opioid for moderate to severe acute, postoperative, and cancer-related pain (8).
Morphine undergoes first-pass metabolism in the liver and gut. It is well absorbed and distributed throughout the body. Its main metabolites are morphine-3-glucuronide and morphine-6-glucuronide. Its mean plasma elimination half-life after intravenous administration is about 2 hours. Approximately 90% of morphine is excreted in the urine within 24 hours (8).
Available Forms
Morphine is available in various forms, including.
- immediate-release tablets
- extended release tablets
- oral IR solutions
- injectable solutions
- transdermal patches
Dosing and Monitoring
Morphine is hydrophilic and, as such, has a slow onset time. The advantage of this is that it is unlikely to cause acute respiratory depression even when injected. However, because of the slow onset time, there is more likelihood of morphine overdose due to the ability to “stack” doses in patients experiencing severe pain (Bistas, Lopez-Ojeda, & Ramos-Matos, 2023).
The dosing of morphine depends on the patient's pain severity, previous opioid exposure, and other factors. It is usually initiated at a low dose and titrated upwards as needed. Monitoring pain relief, adverse effects, and signs of opioid toxicity is crucial. Reevaluate benefits and harms with patients within 1 to 4 weeks of starting opioid therapy or of dose escalation. General recommendations for initiating morphine (Bistas, Lopez-Ojeda, & Ramos-Matos, 2023).
Prescribe IR opioids instead of ER opioids.
Prescribe the lowest effective dosage, below 50 Morphine Milligram Equivalents (MME) /day.
Side Effects and Contraindications
Because morphine binds to opioid receptors in the brain and spinal cord, is metabolized in the liver and gut, and has a slow onset, the following side effects are common:
- Constipation
- Nausea
- Vomiting
- Sedation
- Dizziness
- Respiratory depression
- Pruritis
- Sweating
- Dysphoria/Euphoria
- Dry mouth
- Anorexia
- Spasms of urinary and biliary tract
Contraindications of morphine are:
- Known hypersensitivity or allergy to morphine.
- Bronchial asthma or upper airway obstruction
- Respiratory depression in the absence of resuscitative equipment
- Paralytic ileus
- Risk of choking in patients with dysphagia, including infants, children, and the elderly (8)
Concurrent use with other sedating medications: Amitriptyline, diazepam, haloperidol, chlorpromazine
Morphine interacts with the following medications:
- Ciprofloxacin
- Metoclopramide
- Ritonavir
Considerations for Nurse Practitioners
Assess for medical conditions that may pose serious and life-threatening risks with opioid use, such as the following:
- Sleep-disordered breathing, such as sleep apnea.
- Pregnancy
- Renal or hepatic insufficiency
- Age >= 65
- Certain mental health conditions
- Substance use disorder
- Previous nonfatal overdose
Fentanyl
Mechanism of Action and Metabolism
Fentanyl is a synthetic opioid more potent than morphine and was approved in 1968. Fentanyl is an agonist that works by binding to the mu-opioid receptors in the central nervous system. This binding inhibits the transmission of pain signals, resulting in analgesia. Fentanyl is often used for severe pain management, particularly in the perioperative and palliative care settings, or for severe pain in patients with Hepatic failure (8).
It is a mu-selective opioid agonist. However, it can activate other opioid receptors in the body, such as the delta and kappa receptors, producing analgesia. It also activates the Dopamine center of the brain, stimulating relaxation and exhilaration, which is responsible for its high potential for addiction (8).
Indications for fentanyl are as follows:
- Preoperative analgesia
- Anesthesia adjunct
- Regional anesthesia adjunct
- General anesthesia
- Postoperative pain control
- Moderate to severe acute pain (off-label)
Available Forms
- Fentanyl is available in various forms, including:
- transdermal patches
- injectable solutions
- lozenges
- nasal sprays
- oral tablets (8)
Dosing and Monitoring
Fentanyl is metabolized via the CYP3A4 enzyme in the liver. It has a half-life of 3 to 7 hours, and 75% of Fentanyl is excreted in the urine and 9% in feces.
The dosing of fentanyl depends on the route of administration and the patient's needs. For example, transdermal patches are typically applied every 72 hours, while injectable solutions are titrated to achieve the desired analgesic effect. Monitoring should include assessing pain levels, respiratory rate, blood pressure, and sedation scores (8).
Fentanyl is most dosed as follows:
- Post-operative pain control
- 50 to 100 mcg IV/IM every 1 to 2 hours as needed; alternately 0.5 to 1.5 mcg/kg/hour IV as needed. Consider lower dosing in patients 65 and older.
PCA (patient-controlled analgesia): 10 to 20 mcg IV every 6 to 20 minutes as needed; start at the lowest effective dose for the shortest effective duration - refer to institutional protocols (8).
Moderate to severe acute pain (off-label) 1 to 2 mcg/kg/dose intranasally each hour as needed; the maximum dose is 100 mcg. Use the lowest effective dose for the shortest effective duration (8).
Side Effects and Contraindications
Common side effects of fentanyl include:
- respiratory depression
- sedation
- constipation
- nausea
- vomiting
- euphoria
- confusion
- respiratory depression/arrest
- visual disturbances
- dyskinesia
- hallucinations
- delirium
- narcotic ileus
- muscle rigidity
- addiction
- loss of consciousness
- hypotension
- coma
- death (8).
The use of fentanyl is contraindicated in patients in the following situations:
- After operative interventions in the biliary tract, these may slow hepatic elimination of the drug.
- With respiratory depression or obstructive airway diseases (i.e., asthma, COPD, obstructive sleep apnea, obesity hyperventilation, also known as Pickwickian syndrome)
- With liver failure
- With known intolerance to fentanyl or other morphine-like drugs, including codeine or any components in the formulation.
- With known hypersensitivity (i.e., anaphylaxis) or any common drug delivery excipients (i.e., sodium chloride, sodium hydroxide) (8).
Considerations for Nurse Practitioners
Nurse practitioners prescribing fentanyl should thoroughly assess the patient's pain, medical history, and potential risk factors for opioid misuse. They should also educate patients about the proper use, storage, and disposal of fentanyl. It should be used cautiously in patients with respiratory disorders, liver or kidney impairment, or a history of substance abuse. Fentanyl is contraindicated in patients with known hypersensitivity to opioids and those without exposure to opioids.
Alcohol and other drugs, legal or illegal, can exacerbate fentanyl's side effects, creating multi-layered clinical scenarios that can be complex to manage. These substances, taken together, generate undesirable conditions that complicate the patient's prognosis (8).
Hydromorphone
Mechanism of Action and Metabolism
Hydromorphone is a semi-synthetic opioid derived from morphine. It binds to the mu-opioid receptors in the central nervous system. It primarily exerts its analgesic effects by inhibiting the release of neurotransmitters involved in pain transmission, thereby reducing pain perception. Hydromorphone also exerts its effects centrally at the medulla level, leading to respiratory depression and cough suppression (1).
Hydromorphone is indicated for:
- moderate to severe acute pain
- severe chronic pain
- refractory cough suppression (off-label) (1)
Available Forms
Hydromorphone is available in various forms, depending on the patient’s needs and severity of pain.
- immediate-release tablet
- extended release tablets
- oral liquid
- injectable solution
- rectal suppositories
Dosing and Monitoring
The immediate-release oral formulations of hydromorphone have an onset of action within 15 to 30 minutes. Peak levels are typically between 30 and 60 minutes with a half-life of 2 to 3 hours. Hydromorphone is primarily excreted through the urine.
The dosing of hydromorphone should be individualized based on the patient's pain intensity, initiated at the lowest effective dose, and adjusted gradually as needed. Close monitoring of pain relief, adverse effects, and signs of opioid toxicity is essential. Patients should be assessed regularly to ensure they receive adequate pain control without experiencing excessive sedation or respiratory depression.
The following are standard dosages that should only be administered when other opioid and non-opioid options fail.
- Immediate-release oral solutions dosage: 1 mg/1 mLoral tablets are available in 2 mg, 4 mg, and 8 mg.
- Extended-release oral tablets are available in dosages of 8 mg, 12 mg, 16 mg, and 32 mg.
- Injection solutions are available in concentrations of 1 mg/mL, 2 mg/mL, 4 mg/mL, and 10 mg/mL.
- Intravenous solutions are available in strengths of 2 mg/1 mL, 2500 mg/250 mL, ten mg/1 mL, and 500 mg/50 mL.
- Suppositories are formulated at a strength of 3 mg (1).
Side Effects and Contraindications
Hydromorphone has potential adverse effects on several organ systems, including the integumentary, gastrointestinal, neurologic, cardiovascular, endocrine, and respiratory.
Common side effects of hydromorphone include:
- Constipation
- Nausea
- Vomiting
- Dizziness
- Sedation
- respiratory depression
- pruritus
- headache
- Somnolence
- Severe adverse effects of hydromorphone include:
- Hypotension
- Syncope
- adrenal insufficiency
- coma
- raised intracranial pressure.
- seizure
- suicidal thoughts
- apnea
- respiratory depression or arrest
- drug dependence or withdrawal
- neonatal drug withdrawal syndrome
- Hydromorphone is contraindicated in patients with:
- known allergies to the drug, sulfites, or other components of the formulation.
- known hypersensitivity to opioids.
- severe respiratory depression
- paralytic ileus
- acute or severe bronchial asthma (1).
Caution should be exercised in patients with:
- respiratory insufficiency
- head injuries
- increased intracranial pressure.
- liver or kidney impairment.
Considerations for Nurse Practitioners
As nurse practitioners, it is crucial to assess the patient's pain intensity and overall health status before initiating Hydromorphone. Start with the lowest effective dose and titrate carefully for optimal pain control. Regular monitoring for adverse effects, signs of opioid toxicity, and therapeutic response is essential. Educate patients about the potential side effects, proper dosing, and the importance of not exceeding prescribed doses. Additionally, nurse practitioners should be familiar with local regulations and guidelines regarding opioid prescribing and follow appropriate documentation and monitoring practices.
Additional Considerations
In terminal cancer patients, clinicians should not restrain opioid therapy even if signs of respiratory depression become apparent.
Hydromorphone requires careful administration in cases of concurrent psychiatric illness.
Specific Patient Considerations:
- Hepatic impairment and Renal Impairment: Initiate hydromorphone treatment at one-fourth to one-half of the standard starting dosage, depending on the degree of impairment.
- Pregnancy considerations: Hydromorphone can traverse the placental barrier and induce NOWS.
- Breastfeeding considerations: Nonopioid analgesic agents are preferable for breastfeeding women.
- Older patients: hydromorphone is categorized as a potentially inappropriate medication for older adults (1).
Tramadol
Mechanism of Action and Metabolism
Tramadol is a Schedule IV opioid medication with a higher potential for dependency and misuse than non-opioid medications. It binds to opioid receptors in the central nervous system, inhibiting the reuptake of norepinephrine and serotonin. It also has weak mu-opioid receptor agonist activity.
The liver metabolizes tramadol mediated by the cytochrome P450 pathways (particularly CYP2D6) and is mainly excreted through the kidneys.
Tramadol is used for moderate to severe pain.
Available Forms of Tramadol include:
- Immediate-release-typically used for acute pain management.
- Extended-release-used for chronic pain.
Dosing and Monitoring
Tramadol has an oral bioavailability of 68% after a single dose and 90–100% after multiple doses and reaches peak concentrations within 2 hours. Approximately 75% of an oral dose is absorbed, and the half-life of tramadol is 9 hours (18).
Tramadol dosing should be individualized based on the patient's pain severity and response.
The initial dose for adults is usually 50-100 mg orally every 4-6 hours for pain relief. The maximum daily dose is 400 mg for immediate-release formulations and 300 mg for extended-release formulations (18).
It is essential to monitor the patient's pain intensity, response to treatment, and any adverse effects. Regular reassessment and adjustment of the dosage may be necessary.
Side Effects and Contraindications
Tramadol is responsible for severe intoxications leading to consciousness disorder (30%), seizures (15%), agitation (10%), and respiratory depression (5%). The reactions to Tramadol suggest that the decision to prescribe should be carefully considered.
Common Side Effects of Tramadol Include:
- Nausea
- Vomiting
- Dizziness
- Constipation
- Sedation
- Headache
- CNS depression
- Seizure
- Agitation
- Tachycardia
- Hypertension
- reduced appetite
- pruritus and rash
- gastric irritation
Serious side effects include:
- respiratory depression
- serotonin syndrome
- seizures
Contraindications
Tramadol is contraindicated in patients with:
- history of hypersensitivity to opioids
- acute intoxication with alcohol
- opioids, or other psychoactive substances
- Patients who have recently received monoamine oxidase inhibitors (MAOIs)
Additionally, the following can be observed in tramadol intoxication:
- miosis
- respiratory depression
- decreased level of consciousness
- hypertension
- tremor
- irritability
- increased deep tendon reflexes
Poisoning leads to:
- multiple organ failure
- coma
- cardiopulmonary arrest
- death
Considerations for Nurse Practitioners
Tramadol has been increasingly misused with intentional overdoses or intoxications. Suicide attempts were the most common cause of intoxication (52–80%), followed by abuse (18–31%), and unintentional intoxication (1–11%). Chronic tramadol or opioid abuse was reported in 20% of tramadol poisoning cases. Fatal tramadol intoxications are uncommon except when ingested concurrent with depressants, most commonly benzodiazepines and alcohol (18).
Tramadol poisoning can affect multiple organ systems:
- gastrointestinal
- central nervous system: seizure, CNS depression, low-grade coma, anxiety, and over time anoxic brain damage
- Cardiovascular system: palpitation, mild hypertension to life-threatening complications such as cardiopulmonary arrest
- respiratory system
- renal system: renal failure with higher doses of tramadol intoxication
- musculoskeletal system: rhabdomyolysis
- endocrine system: hypoglycemia, serotonin syndrome (18)
Cannabis
Mechanism of Action and Metabolism
Cannabis is classified as a Schedule I status. It contains various cannabinoids, with delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) being the most studied. THC primarily acts on cannabinoid receptors in the brain, producing psychoactive effects, while CBD has more diverse effects on the nervous system. These cannabinoids interact with the endocannabinoid system, modulating neurotransmitter release and influencing various physiological processes (32).
Similar to opioids, cannabinoids are synthesized and released in the body by synapses that act on the cannabinoid receptors present in presynaptic endings (32). They perform the following actions related to analgesia:
- Decrease the release of neurotransmitters.
- Activate descending inhibitory pain pathways.
- Reduce postsynaptic sensitivity and alleviate neural inflammation.
- Modulate CB1 receptors within central nociception processing areas and the spinal cord, resulting in analgesic effects.
- Attenuate inflammation by activating CB2 receptors (32).
- Emerging research shows cannabis is indicated for:
- Migraines
- chronic pain
- back pain
- arthritic pain
- pain associated with cancer and surgery.
- neuropathic pain
- diabetic neuropathic pain when administered early in the disease progression.
- sickle cell disease
- cancer
- inflammatory bowel disease (32)
Available Forms
Cannabis refers to products sourced from the Cannabis sativa plant. There are differences between cannabis, cannabinoids, and cannabidiol (CBD). Cannabinoids are extracted from the cannabis plants. Cannabinoid-based treatments, such as dronabinol and CBD, are typically approved medical interventions for specific indications. THC (9-tetrahydrocannabinol) is the psychoactive component of the cannabis plant. CBD is a non-psychoactive component (32).
Cannabis can be consumed in different forms, each with a different onset and duration. Patients may have individual preferences, including:
- smoking/vaporizing dried flowers.
- consuming edibles
- tinctures or oils
- applying topicals (32)
Dosing and Monitoring
Inhaling marijuana via the lungs by smoking or vaping causes maximum plasma concentration within minutes. Psychiatric effects begin within seconds to a few minutes after inhalation and peak after 15 to 30 minutes. The effect diminishes throughout 2 to 3 hours (32).
Oral ingestion of marijuana causes psychiatric effects that typically occur between 30 and 90 minutes and reach maximum effect after 2 to 3 hours. Ingested marijuana effects last about 4 to 12 hours (32).
Dosing cannabis is challenging due to variations in potency and individual responses. Start with low doses and titrate slowly to achieve the desired effect while minimizing side effects. Regular monitoring is crucial, including assessing symptom relief, adverse effects, and potential drug interactions. Encourage patients to keep a diary to track their cannabis use and its effects (32).
Side Effects and Contraindications
Cannabis can exacerbate mental health conditions such as anxiety and psychosis. Common side effects of cannabis include (32):
- Dizziness
- dry mouth
- increased heart rate
- impaired memory
- psychoactive effects
Contraindications include:
- Pregnancy
- Breastfeeding
- heart disease
- respiratory conditions
- history of substance abuse
- mental health disorders

Case Study
Mary is agreeable to trying an increased dose of Gabapentin. Mary would also like to see a counselor to discuss her past and get help with her anxiety. You made an appointment for Mary to see a Licensed Clinical Social Worker in your clinic.
You read the side effects and warnings for Gabapentin, and it is unsafe to use Gabapentin and Tramadol together since they are both depressants. You order a non-steroidal drug for Mary's somatic knee pain and make a consult for imaging studies on her left knee. You also make a referral to Orthopedics.
You educated Mary about the side effects of Gabapentin and scheduled a follow-up appointment. The day after Mary began her treatment with the increased Gabapentin, you called Mary to follow up on its effect. Mary still has pain, but she is not having any untoward side effects. Gabapentin may not work immediately so you will schedule a follow-up call in 3 days.

Opioid Use, the Opioid Epidemic, and Statistics
The use and misuse of opioids has become a pressing public health concern, leading to a global epidemic. The history of opioid use, the opioid epidemic, and associated statistics provide essential context for healthcare professionals in addressing this public health crisis. More importantly, it is estimated that 1 in 4 patients receiving prescription opioids in primary care settings will misuse them. In addition, 50% of opioid prescriptions are written by primary care providers, including nurse practitioners (22). Understanding the factors contributing to the epidemic and the magnitude of its impact is crucial for effective prevention, intervention, and treatment strategies.
History of Opioid Use
Opioids have a long history of medicinal use, dating back to ancient civilizations. They have been a drug of choice for pain relief for thousands of years. The introduction of synthetic opioids in the 19th century, such as morphine and later heroin, revolutionized pain management. However, their potential for addiction and misuse soon became apparent (16).
The Opioid Epidemic
The opioid epidemic refers to the surge in opioid misuse, addiction, and overdose deaths. The epidemic gained momentum in the late 1990s with increased prescribing of opioids for chronic pain (43).
No doubt, increased prescribing put opioids in the hands of consumers, but increased prescribing resulted from a multifactorial influence. One of the main influences was aggressive marketing by pharmaceutical companies, which has been well publicized. However, due to the long history of underprescribing pain medications for fear of misuse and addiction, the medical community was primed to expand its opioid prescribing practices (31).
A historical event that increased comfort with prescribing opioids, in the writer's opinion, was the introduction of the Medicare Hospice Benefit in 1986. Medical directors must be contracted or employed by hospices, and these medical directors had or soon gained pain management expertise. To further promote hospice and effective pain management, the hospice medical directors, with newly acquired skills, provided education throughout medical communities about pain management and specifically to decrease the fear of using opioids. Pharmacies and attending physicians grew accustomed to giving opioids for home use. Hospice care is for terminally ill patients, defined as a life expectancy of 6 months or less. Still, the reality is that hospice discharges 12 to 40% of patients for ineligibility and other reasons.
A more prominent factor in increasing opioid prescribing was the 1996 American Pain Society's introduction of pain as "the 5th Vital sign." Soon after, The Joint Commission promoted pain as "the 5th Vital Sign" and began compliance surveys in healthcare organizations requiring pain assessment details to be as prominent as blood pressure and heart rate. The Joint Commission cited a quote from 1968 by a nurse from the University of California Los Angeles, Margo McCaffrey, who defined pain as "…Whatever the experiencing person says it is, existing whenever s/he says it does." The Joint Commission accreditation programs pursued pain management as part of the accreditation process throughout its healthcare accreditation programs, including hospice accreditation by 1989 per TJC Timeline (48).
The National Institute of Health published an article about the Joint Commission's role in the opioid epidemic, particularly regarding the definition of pain, "This definition emphasizes that pain is a subjective experience with no objective measures. It also stresses that the patient, not the clinician, is the authority on the pain and that their self-report is the most reliable indicator of pain. This set the tone for clinicians: Patients are always to be trusted to report pain accurately” (45).
Statistics on the Opioid Epidemic
In the United States alone, over 500,000 people died from opioid overdoses between 1999 and 2017. The number of opioid-related overdose deaths continues to increase, with synthetic opioids, mainly illicitly manufactured Fentanyl, playing a significant role in recent years (46). Fentanyl-laced drugs, such as marijuana, are increasingly sold knowing and unknowingly to introduce medications with a high addiction rate, thus creating new consumers. This practice can potentially increase deaths due to the imprecise nature of manufacturing (16).
Opioid-related hospitalizations have also risen substantially. In 2014, there were approximately 1.27 million hospitalizations related to opioids in the United States. These hospitalizations not only place a burden on healthcare systems but also reflect the severe consequences of opioid misuse (3).

Federal Regulations on Opioid Prescribing
The history of substance use disorder prevention that promotes opioid recovery and treatment for patients and communities can be traced back to the early 20th century. However, the current approach to addressing opioid addiction and promoting healing has evolved significantly in recent times (36).
In the early 1900s, health professionals treated opioid addiction with punitive measures, including incarceration and moralistic approaches. The focus was on punishing individuals rather than providing effective treatment. This approach persisted for several decades until the mid-20th century when the medical community started recognizing addiction as a medical condition rather than a moral failing (36).
The Controlled Substances Act (CSA), introduced in 1970, was a response to increasing drug abuse and illicit drug trafficking in the United States. The CSA is a federal law regulating the manufacture, possession, distribution, and use of certain substances, including drugs and medications, that can potentially cause abuse and dependence. Its primary purpose is to combat drug abuse, reduce drug-related crimes, and protect public health and safety. The Drug Enforcement Agency (DEA) plays a crucial role in enforcing the CSA by monitoring and controlling controlled substance production, distribution, and use (31).
In the 1990s, the significant increase in opioid prescribing, leading to a surge in opioid addiction and overdose deaths, prompted a shift in focus toward prevention. Efforts were made to educate healthcare providers about the risks of overprescribing opioids and to implement prescription drug monitoring programs to track and prevent abuse (36).
The Comprehensive Addiction and Recovery Act (CARA) was signed into law in 2016 to expand access to treatment and recovery services for opioid addiction. This legislation allocated funding for prevention, treatment, recovery, and support services while promoting evidence-based practices and programs (36).
The Centers for Disease Control and Prevention (CDC) published guidelines in 2016 for prescribing opioids for chronic pain, which was updated in 2022. These guidelines emphasize the importance of non-opioid alternatives, using the lowest effective dose for the shortest duration, and assessing the benefits and risks of continued opioid therapy (13).
Furthermore, the Substance Use Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act (SUPPORT) was signed into law in 2018, providing additional resources to address the opioid crisis. This legislation expanded access to medication-assisted treatment (MAT), increased the availability of naloxone, a medication used to reverse opioid overdose, and enhanced support for recovery housing (36).
In recent years, there has been a growing recognition of the importance of a comprehensive approach to opioid addiction, including harm reduction strategies, increased access to naloxone, and the integration of mental health services. Communities and organizations have been working together to address the underlying issues contributing to addiction, such as poverty, trauma, and social determinants of health (50).
Overall, the history of substance use disorder prevention that promotes opioid recovery and treatment has evolved from a punitive approach to a more compassionate and evidence-based model. Efforts are now focused on prevention, early intervention, and expanding access to comprehensive treatment and support services for individuals and communities affected by opioid addiction (36).
The most current federal regulations on opioid prescribing for healthcare providers are the amendments to the CSA in 2018, which added new rules to limit the quantity and duration of opioid prescriptions for acute pain to seven days. In 2022, the CDC updated recommendations to the Clinical Practice Guidelines for Prescribing Opioids for Pain.
The 2022 CDC guidelines are summarized below (13):
- Non-opioid therapies should be considered the first-line treatment for chronic pain.
- Establish clear treatment goals with patients, including realistic pain management and functional improvement expectations.
- Conduct a thorough risk assessment for potential harms before initiating opioid therapy.
- When opioids are used, start with the lowest effective dose and consider immediate-release opioids instead of extended-release or long-acting opioids.
- Prescribe the lowest effective dose for the shortest duration possible, typically three days or less and rarely exceeding seven days.
- Reassess benefits and risks within one day after prescribing opioids, including checking the prescription drug monitoring database.
- Avoid prescribing opioids and benzodiazepines concurrently whenever possible due to the increased risk of overdose and death.
- Offer naloxone to patients at increased risk of opioid overdose, including those with a history of overdose, substance use disorder, or concurrent benzodiazepine use.
- When opioids are no longer needed, taper the dose gradually to minimize withdrawal symptoms.
- Arrange an evidence-based treatment for patients with opioid use disorder, including medication-assisted treatment (Naltrexone, Buprenorphine, or Methadone).

Safe Prescribing and Prescription Monitoring Program
Prescription Drug Monitoring Programs (PDMP) are state-run electronic databases that track.
the prescribing and dispensing of controlled substances. PDMPs are designed to improve patients.
care and safety by giving clinicians access to patients' prescription histories, allowing them to make informed decisions when prescribing controlled substances. PDMPs help identify patients at risk of substance misuse or prescription drug overdose. They also enable clinicians to identify potential drug interactions and prevent opioid diversion (14).
PDMPs collect and store data from pharmacies and prescribers in a centralized database. Clinicians can access this database to review a patient's prescription history, including the types of medications prescribed, the prescribers involved, and the dispensing pharmacies (14).
In many states, PDMP use is mandated by law, and nurse practitioners may be required to register and use the system. It is essential to understand state-specific laws and regulations regarding PDMP use.
PDMPs have some limitations, such as incomplete data or delays in reporting. The CDC emphasizes that clinicians should use PDMP data for their clinical assessment and other relevant information to make informed decisions about prescribing controlled substances. Still, PDMP cannot be used as the sole basis for denying or providing treatment (14).
Case Study
After five days on Gabapentin, Mary was doing well, and her neuropathic pain had decreased to 3/10. However, Mary suffered a fall after her knee "gave out" and injured her knee and back. She was in severe pain, and her family drove her to the ER. The ER doctors saw Mary, and orthopedics were consulted. Mary has surgery scheduled for a knee replacement a week from now.
Mary was prescribed Vicodin because she was in excruciating pain, but her prescription only allowed enough medication for two days. Mary has made an appointment with you to renew her prescription.
You evaluate Mary because you know that concomitant use of Gabapentin and opioids puts Mary at risk for respiratory depression and possible side effects, including accidental overdose.
Mary stated she has been more alert the past 24 hours and is afraid her functional status will continue to decline if she does not have more Vicodin because the pain in her back and knee makes it difficult to stand. You assess Mary. Mary stated she occasionally drinks alcohol but has not had a drink since she moved. She has no familial history of substance abuse or mental health disorders.
Mary's mother stayed at her house to help her for the first 24 hours after Mary's return from the ER, but Mary is providing her care now.
You check the PDMP database and see that Mary was prescribed eight pills she has taken over the last 48 hours.
Since the Vicodin has been effective without untoward side effects, and Mary's function is improving, you decide to refill the prescription of Vicodin. You will taper the dose to three Vicodin daily for two days and two for one day. Mary will be near her appointment for a knee replacement as well.

Preventing Opioid Use Disorder
As previously discussed, opioid addiction is a growing concern worldwide, affecting individuals from all walks of life. According to the CDC, "Anyone who takes prescription opioids can become addicted to them" (14).
As frontline healthcare professionals, nurse practitioners must recognize the signs of opioid addiction to provide timely intervention and support. This section will outline the key indicators of opioid addiction.
Physical Symptoms
Physical symptoms are often the first noticeable signs of opioid addiction. These symptoms may include constricted pupils, drowsiness, slurred speech, impaired coordination, and increased sensitivity to pain. Additionally, individuals struggling with opioid addiction may exhibit frequent flu-like symptoms, such as a runny nose, sweating, itching, or gastrointestinal issues.
Behavioral Changes
Opioid addiction can significantly impact an individual's behavior. These may include increased secrecy, frequent requests for early prescription refills, doctor shopping (seeking prescriptions from multiple healthcare providers), neglecting personal hygiene, and experiencing financial difficulties due to excessive spending on opioids (37).
Social Isolation
Opioid addiction often leads to social withdrawal and isolation. Individuals struggling with opioid addiction may distance themselves from family, friends, and social activities they once enjoyed. They may exhibit erratic mood swings, become defensive or hostile when confronted about their drug use, and display a general lack of interest in previously important activities (30).
Psychological Changes
The psychological impact of opioid addiction is significant. Individuals with opioid addiction may exhibit increased anxiety, depression, irritability, and restlessness. They may also experience cognitive impairments, memory lapses, and difficulties in decision-making. Healthcare professionals should be attentive to these changes, as they can indicate opioid addiction (51).
Tolerance and Withdrawal Symptoms
The development of tolerance and withdrawal symptoms are critical signs of opioid addiction. Individuals may require increased dosages of opioids to achieve the desired effect, indicating a growing tolerance. Furthermore, withdrawal symptoms such as muscle aches, nausea, vomiting, insomnia, and intense cravings for opioids may occur when the drug is discontinued or reduced abruptly (51).

- How do you ensure appropriate documentation when prescribing controlled substances?
Opioid Overdose
The management of opioid overdose, withdrawal, and addiction requires a comprehensive approach that combines pharmacological interventions with psychosocial support. Naloxone remains a vital tool for reversing opioid overdose, while medications such as Methadone, buprenorphine, and naltrexone play crucial roles in withdrawal and addiction treatment (National Institute of Health, 2023). Nurse practitioners must stay vigilant and informed about the evolving landscape of medications. This section aims to provide a comprehensive review of medications and treatment strategies for opioid overdose, withdrawal, and addiction and is excerpted from the NIH (40).
Naloxone
Mechanism of Action and Metabolism
Naloxone is an opioid receptor antagonist. It works by binding to opioid receptors and displacing any opioids present, thereby reversing the effects of opioid overdose. It has a higher affinity for opioid receptors than most opioids, effectively blocking their action.
Naloxone is indicated for emergency intervention of opioid overdose. It effectively reverses respiratory depression and other life-threatening effects. Studies suggest the potential benefits of combining naloxone with other medications, such as buprenorphine (see below), to improve outcomes. Initiatives promoting community-based naloxone distribution programs have shown promising results in reducing opioid-related deaths.
Available Forms
Naloxone is available in various formulations:
- Intranasal
- Intramuscular
- Intravenous
- auto-injectors.
The most used form is the intranasal spray, which is easy to administer and requires no specialized training. Intranasal naloxone formulations have gained popularity due to their ease of use and increased availability. A recent study showed that the non-FDA-approved compound spray was far less effective than either FDA compound (15).
Dosing and Monitoring
The recommended initial dose of naloxone for opioid overdose is 2mg intranasally or 0.4mg to 2mg intramuscularly or intravenously. If the patient does not respond within 23- minutes, additional doses may be administered every 2-3 minutes. Continuous monitoring of the patient's respiratory status is essential, as repeat doses may be required due to the short half-life of naloxone.
Side Effects and Contraindications
Naloxone has been shown not to affect individuals without opioids in their system.
Common side effects of naloxone include
- Withdrawal symptoms: increased heart rate, sweating, and agitation
- nausea
- vomiting
- headache
Contraindications include known hypersensitivity to naloxone and situations where the use of naloxone may be unsafe or not feasible.
Considerations for Nurse Practitioners
Fentanyl and other opioids have a rapid onset, and the need to act quickly is paramount. As mentioned previously, the ease of use and higher plasma concentrations using the FDA-approved 4-mg FDANxSpray device compared with the locally compounded nasal sprays should be considered when ordering Naloxone (15).
Fentanyl and other potent synthetic opioids may require multiple administrations of naloxone to achieve reversal of an overdose (Chiang, Gyaw, & Krieter, 2019). As a nurse practitioner prescribing naloxone, it is crucial to assess the patient's risk factors for opioid overdose, such as a history of substance use disorder or chronic pain management. Education regarding the proper administration of naloxone should be provided to the patients and their caregivers. Additionally, it is essential to provide resources for follow-up care, including addiction treatment and ongoing support.
Methadone
Mechanism of Action and Metabolism
Methadone is a long-acting opioid agonist that effectively suppresses withdrawal symptoms and reduces cravings. It binds to the same opioid receptors in the brain as other opioids. It relieves withdrawal symptoms and reduces cravings by blocking the euphoric effects of opioids, thus helping individuals with opioid dependence to achieve stability (33).
Available Forms
Methadone is available in oral tablets and liquid formulations. The oral tablet is the most used form and is typically administered once daily (33).
Dosing and Monitoring
Methadone dosing is individualized based on the patient's response and needs. Initially, the dose often started low and gradually increased until the patient reached a stable dose. Dosing may need to be adjusted based on the patient's response, adherence, and any changes in their overall health. Regularly monitoring the patient's vital signs, urine drug screens, and assessment of their withdrawal symptoms and cravings is essential.
Side Effects and Contraindications
Common side effects of methadone include:
- Constipation
- dry mouth
- drowsiness
- sweating
- weight gain
- respiratory depression
Contraindications include:
- known hypersensitivity to methadone
- severe asthma
- respiratory depression
- certain heart conditions (33).
Considerations for Nurse Practitioners
As a nurse practitioner prescribing methadone, conducting a comprehensive assessment of the patient's medical history, current medications, and substance use history is crucial. Opioid treatment programs or specialized clinics are often involved in methadone treatment, so collaboration and coordination of care with these programs are essential. Regularly monitoring the patient's progress, adherence, and potential side effects or drug interactions is essential. Additionally, providing education on the risks and benefits of methadone and the importance of adherence to the prescribed regimen is crucial for successful treatment outcomes.
Buprenorphine
Mechanism of Action and Metabolism
Buprenorphine is a partial opioid agonist with a ceiling effect that minimizes the risk of overdose while reducing withdrawal symptoms. Buprenorphine is a partial opioid agonist that binds to the same receptors as other opioids but produces a weaker response. It has a high affinity for the mu-opioid receptors, which helps reduce cravings and withdrawal symptoms in individuals with opioid dependence.
Available Forms
Buprenorphine is available in different formulations, including sublingual tablets, buccal films, and extended-release injections. The sublingual tablets have different strengths, such as 2mg, 4mg, 8mg, and 12mg. Buprenorphine is taken as a daily tablet or weekly or monthly injection.
Dosing and Monitoring
The dosing of buprenorphine varies depending on the individual's opioid dependence severity and treatment phase. Initially, a low dose (e.g., 2-4mg) is given, and it may gradually increase to a maintenance dose of 8-24 mg daily. Regular monitoring is essential to assess the patient's response, adherence, and potential side effects.
Side Effects and Contraindications
Common side effects of buprenorphine include:
- Constipation
- Nausea
- Headache
- Insomnia
- Sweating
Serious side effects are rare but can include:
- Respiratory depression
- Allergic reactions
Buprenorphine is contraindicated in individuals with:
- Severe respiratory insufficiency
- Acute intoxication with opioids
- Known hypersensitivity
Considerations for Nurse Practitioners
Nurse practitioners can prescribe buprenorphine for opioid dependence treatment under the Drug Addiction Treatment Act (DATA). To become eligible, they must complete specific training requirements and obtain a waiver from the Substance Abuse and Mental Health Services Administration (SAMHSA). Nurse practitioners should assess patients thoroughly, including their opioid use history, comorbidities, and medication compatibility, while ensuring appropriate counseling and referral for comprehensive treatment (40).
Clonidine + Lofexidine
Mechanism of Action and Metabolism:
Both Clonidine and Lofexidine are alpha-2 adrenergic agonists. They work by stimulating alpha-2 receptors in the brain, which reduces sympathetic outflow and norepinephrine release. This results in decreased sympathetic activity, leading to various effects such as reduced blood pressure, decreased heart rate, and alleviated withdrawal symptoms (28).
Available Forms
Clonidine is available in oral tablets and patches. Lofexidine is available in oral tablets and is taken as needed (40).
Dosing and Monitoring
For opioid withdrawal, the Clonidine dose ranges from 0.1-0.3 mg every 4-6 hours. Lofexidine is usually initiated at 0.53 mg three times daily, and the dose can be increased to 2.88 mg daily. Monitoring blood pressure and heart rate is essential during treatment (40).
Side Effects and Contraindications:
Common side effects of both medications include:
- dry mouth
- sedation
- dizziness
- constipation
- orthostatic hypotension (40).
Both medications are contraindicated in patients with:
- Hypotension
- Bradycardia
- heart block
- history of hypersensitivity to the drugs (40).
Considerations for Nurse Practitioners:
An early study of lofexidine vs. clonidine for withdrawal symptoms showed that treatment with lofexidine resulted in lower withdrawal symptoms, fewer mood problems, less sedation, and hypotension. There were no significant differences in craving levels, morphine metabolites in urine, or dropout rates when both were compared.
Lofexidine can be a safe option for outpatient treatment as it does not lead to hypotension. However, nurse practitioners must closely monitor patients' blood pressure and heart rate during treatment and educate them about possible side effects. If patients experience any concerning symptoms, they should inform their nurse practitioner immediately.
Gradual dose reduction of Clonidine is crucial to prevent rebound hypertension. Before prescribing either medication, nurse practitioners should assess for any contraindications or potential drug interactions (19).
Emerging Therapies for Withdrawal
Extended-release naltrexone: Naltrexone is an opioid receptor antagonist that blocks the effects of opioids, reducing the risk of relapse. It is taken as a monthly injection.
Alpha-2 adrenergic agonists: Emerging evidence suggests the potential use of dexmedetomidine and guanfacine for managing opioid withdrawal symptoms.
Medication-Assisted Treatment (MAT):
Methadone was introduced in the 1960s and marked a significant turning point in opioid addiction treatment or MAT. Along with counseling and behavioral therapies, MAT became the cornerstone of opioid addiction recovery.
Examples of medications used:
- Methadone
- Buprenorphine:
- Naltrexone:
Adjunctive Pharmacotherapies:
Antidepressants: Selective serotonin reuptake inhibitors and tricyclic antidepressants may help manage co-occurring depression and anxiety.
Anticonvulsants:
Medications like Gabapentin and pregabalin show promise in reducing opioid cravings and improving treatment outcomes.

Other Substance Use Disorders
Patients in pain may struggle with Substance Use Disorders other than Opioid Use Disorder. Substance use disorders may often occur with mental health conditions such as anxiety, depression, and bipolar disorder. In addition, many individuals engage in polydrug use. Understanding the most common Substance Use Disorders aids in a comprehensive assessment of the patient and the development of appropriate treatment plans (28).
Alcohol Use Disorder (AUD):
The prevalence of AUD worldwide was estimated to be 9.8% in men and 5.5% in women in 2016 (28).
Cannabis Use Disorder (CUD):
the prevalence of CUD in the United States increased from 2.18% in 2001-2002 to 2.89% in 2012-2013. (28).
Cocaine Use Disorder:
According to the National Survey on Drug Use and Health (NSDUH), in 2019, approximately 1.9 million Americans aged 12 or older had cocaine use disorder in the past year (44).
Methamphetamine Use Disorder:
A study published in Drug and Alcohol Dependence reported that the prevalence of methamphetamine use disorder in the United States was estimated to be 0.2% in 2015-2016 (6).

Drug Diversion and Illegal opioids
Misuse of opioids is facilitated by diversion and is defined as "the transfer of drugs from lawful to unlawful use" (24). Most commonly, this occurs when family and friends share prescribed opioids with other family and friends. Opioids and other controlled drugs are also diverted from healthcare facilities. Statistics show that healthcare facility diversion has increased since 2015 (24)
Diversion affects patients, healthcare workers, healthcare facilities, and public health. Patients experience substandard care due to ineffective pain management and impaired healthcare workers. In addition, affected patients are at risk of infections from compromised syringes (24).
Healthcare employees who divert are at risk of overdose and death. If caught, they face criminal prosecution and malpractice suits. Healthcare facilities also bear the cost of diverted drugs via internal investigations, follow-up care for affected patients, regulatory fines for inadequate safeguards, and declining public trust (24).
Despite the enormous consequences of drug diversion, healthcare facilities have implemented few processes to detect and deter the diversion of controlled substances (24).

- What protocols can nurse practitioners implement to prevent drug diversion within their healthcare setting?
Patient Teachings and Considerations
Opioids have significant side effects and carry a risk of addiction and overdose. Nurse practitioners can decrease the risks of misuse and addiction by educating patients on appropriate disposal, safe storage, and potential signs of addiction. Taking additional time to provide teaching nurse practitioners can promote patient safety, informed decision-making, and responsible opioid use.
Safe Storage and Disposal:
- Teach patients to store opioids securely, out of reach of children, pets, visitors, and non-caregiver family members, to prevent accidental ingestion or misuse (13). Only the caregiver, if applicable, or the patient should have access to pain medications.
- Instruct patients on proper disposal methods, such as using drug take-back programs or mixing opioids with undesirable substances (e.g., coffee grounds) before throwing them away (11) (13).
Medication Adherence:
- Emphasize the importance of taking opioids as prescribed, at the correct dose and frequency, to achieve optimal pain relief.
- Encourage patients to notify their healthcare provider if they experience inadequate pain control or side effects (35).
Potential Side Effects:
- Educate patients about common side effects of opioids, including constipation, nausea, sedation, and respiratory depression.
- Discuss strategies to manage side effects, such as maintaining adequate hydration, consuming a fiber-rich diet, and using over-the-counter laxatives as needed (11).
Risk of Dependence and Addiction:
- Explain the potential for opioid dependence and addiction, especially with long-term use or a history of substance abuse.
- Encourage patients to promptly report signs of opioid misuse, such as craving, loss of control, or continued use despite negative consequences (51).
Avoiding Alcohol and Other Central Nervous System Depressants:
- Instruct patients to avoid consuming alcohol or other medications that can enhance the sedative effects of opioids, increasing the risk of respiratory depression.
- Advise patients to contact the Nurse Practitioner before starting new medications, including over-the-counter drugs or herbal supplements (2).
Driving and Operating Machinery:
- Inform patients about the potential impairment caused by opioids, including reduced alertness, reaction time, and coordination.
- Advise patients to avoid driving or operating heavy machinery while taking opioids until they know how the medication affects them (14).

Case Study
You take some extra time with Mary to educate her on the taper dose of Vicodin, the potential for harm, and the risk of opioids, especially when used concomitantly with Gabapentin. You let Mary know it is unsafe to use alcohol, not only with Vicodin but also with Gabapentin. You let Mary know that Vicodin has a risk of dependency and misuse and, therefore, she will be monitored carefully. You also educate that Mary should store the Vicodin away from visibility by anyone but herself since she can self-administer her medication. You let Mary know that Vicodin can cause constipation and that she should increase her water intake and take a stool softener.
You ask Mary to call you if her pain is not adequately relieved or if her medications run out before the three days.
You let Mary know that if she does stop taking the Vicodin before she has completed all the medication, she should dispose of it by mixing the pills with liquid and coffee grounds to make them unpalatable to animals and others.
Mary complied with your education, completed her course of Vicodin, and was scheduled for surgery. Mary's social worker helped her communicate with her new employer and delayed her start date until after her recovery.
During her recovery, Mary received physical therapy and a short course of pain medication managed by her orthopedist.
Mary returned to the clinic for a follow-up visit after completing her therapy and before starting work. Mary's pain level in her knee is 3/10, and she already feels like she can walk further than pre-surgery. Gabapentin has continued to help Mary's neuropathic pain in her back, and she reports 2/10. Mary looks forward to beginning her new job and is optimistic about the future.
Conclusion
Pain management is the leading cause of primary care appointments and chronic pain is the leading cause of disability. Yet, prescribing opioids for primary care patients is also a factor in drug misuse and the opioid epidemic. Nurse practitioners are challenged to appropriately treat pain and effectively control diversion, addiction, and death from overdose.
It is imperative that nurse practitioners use evidence-based practices to assess, appropriately intervene, and educate about the benefits and potential harm caused by treatment with opioids. Nurse practitioners must stay up to date with the current federal regulations regarding PDMPs, clinical prescribing guidelines, and emerging treatments for pain and opioid abuse disorders.
Anticoagulant Therapy
Introduction
Anticoagulants are a class of medications that prevent and treat blood clots, or venous thromboembolism (VTE).
The Centers for Disease Control and Prevention (CDC) estimates that around 900,000 people in the United States are affected by some form of venous thrombosis every year. Furthermore, the CDC estimates around 60,000 to 100,000 Americans die from some form of venous thromboembolism each year.
They further state that sudden death is the first symptom that occurs in about 25% of people who have a pulmonary embolism [4]. Thus, healthcare providers must be knowledgeable of the signs and symptoms of venous thromboembolism and the available anticoagulants for prevention and treatment.
Understanding the different pharmacokinetics of anticoagulant medication is essential during drug selection. This course outlines anticoagulant pharmacology and addresses pharmacokinetics, including mechanism of action, side effects, usage, and contraindications.
Definitions
Anticoagulants - medications used to prevent and treat blood clot formation, commonly referred to as “blood thinners” [5].
Venous Thromboembolism - a condition where a blood clot forms in a vein, including deep vein thrombosis and pulmonary embolism, and appears during periods of hemostasis [5].
Self Quiz
Ask yourself...
- What are anticoagulants?
- What is a venous thromboembolism?
Medications Overview
Anticoagulant medications are used for the prevention and treatment of venous thromboembolism in both inpatient and outpatient settings.
The major anticoagulant medication classes include:
- Unfractionated Heparin
- Low Molecular Weight Heparin
- Vitamin K Dependent Antagonists
- Direct Oral Anticoagulants
- Direct Thrombin Inhibitors
- Direct Factor Xa Inhibitors [14]
Unlike anticoagulants, antiplatelets act on platelet formation. Although commonly mistaken as an anticoagulant, they are not a part of this class [14].
Depending on the type of anticoagulant, they have other indications for use, such as:
- Atrial Fibrillation stroke prevention
- Left Ventricular Thrombus
- Left Ventricular Aneurysm
- Prosthetic Heart Valve
- Venous Thromboembolism treatment
- VTE prevention in people with cancer
- Pulmonary Embolism
- Pregnancy
- Heparin-Induced Thrombocytopenia

Pharmacokinetics
Unfractionated Heparin
Unfractionated heparin, also known as heparin, is a medication used to prevent excess blood coagulation. It’s used to prevent and treat thrombotic events like deep vein thrombosis (DVT) and pulmonary embolism (PE).
Heparin is also used in patients with atrial fibrillation to prevent blood clot formation and during medical procedures, like dialysis, continuous renal replacement therapy, extracorporeal circulation, and heart catheterizations and surgeries. It’s also used for various off-label indications and usually in inpatient settings, such as acute coronary syndrome, percutaneous coronary intervention (PCI), or as a bridge medication when converting to oral anticoagulants [15].
Heparin works by binding to an antithrombin that inactivates thrombin and thus, blocks the clotting cascade. More specifically, by inactivating thrombin factor IIa and factor Xa, fibrinogen is not converted to fibrin, and in turn, prevents clot formation [15].
Heparin is available via intravenous (IV) and subcutaneous (SQ) forms. Intravenous heparin is infused via continuous infusion until therapeutic levels are achieved, while the SQ form is administered intermittently for VTE prophylaxis. Starting dosages of IV heparin usually begin with a bolus of 80 units per kilogram (kg), and then a continuous infusion rate of 18 units/kg/hour. However, this is dependent on the underlying medical condition being treated and is titrated to achieve therapeutic levels.
In hospital settings, heparin flushes are available to lock and maintain IV-line patency. Additionally, subcutaneous dosages of heparin are weight-based and dependent on the medical condition [15].
Common side effects of heparin include:
- Bleeding
- Thrombocytopenia
- Injection site reactions
- Hyperkalemia
[15]
As bleeding is a common side effect, nurses and healthcare providers must monitor patients for evidence of bleeding. Some signs or symptoms of bleeding can include petechiae, bruising, nosebleeds, hematuria, and bright red or dark, tarry stools. Moreover, heparin-induced thrombocytopenia (HIT) usually occurs within five days of initiating heparin therapy, causing serious adverse effects, like myocardial infarction, stroke, DVT, PE, and even death [15].
Before ordering this medication, healthcare providers should be aware of this anticoagulant’s contraindications. Heparin is contraindicated in individuals who have a platelet count of less than 100,000/mm or they have an active, uncontrolled bleed except if they have disseminated intravascular coagulation (DIC). It should also be avoided in patients with a history of HIT or who cannot have routine blood monitoring of heparin therapeutic levels.
Monitoring the patient’s hemoglobin, hematocrit, and vital signs is also essential to detecting a possible hemorrhage [15].
As heparin affects clotting time, healthcare providers must order therapeutic monitoring for activated partial thromboplastin time (aPTT) and activated clotting time (ACT). Prior to patients being initiated on a heparin infusion, a baseline aPTT level is drawn and then subsequently monitored every 6 hours until a therapeutic aPTT level is achieved. After there are two or more aPTT therapeutic results, then an aPTT is drawn every 24 hours.
The therapeutic range of heparin is typically 1.5 to 2 times the normal range, and titration algorithms are dependent on the healthcare facility’s protocols. ACT monitoring is less specific than aPTT and is typically reserved for PCI or cardiac bypass [15].

Low Molecular Weight Heparin
Another medication used to prevent excess blood coagulation is low molecular weight heparin (LMWH). This medication is used to prevent venous thromboembolic disease in hospitalized patients and is also used to treat DVT and PE. Low molecular weight heparin is also approved for use and treatment of medical conditions such as ST-elevation myocardial infarction (STEMI), unstable angina, and extracorporeal clot prevention.
Common names of LMWH include enoxaparin and dalteparin [13].
Low molecular weight heparin’s mechanism of action works on the body’s clotting cascade by activating antithrombin III. Once antithrombin III is activated, it binds to factor Xa, which inhibits thrombin activation. Therefore, clot formation is prevented since fibrinogen is not converted to fibrin. This medication’s mechanism of action slightly differs from heparin, as LMWH inhibits factor Xa only, while heparin acts on factor IIa and factor Xa [13].
Low molecular weight heparin is available via subcutaneous injection. Dosages of this medication are typically calculated by body weight and are dependent on whether it’s being used for prevention or treatment. LMWH is typically administered once or twice daily and is safe to administer during pregnancy.
Some adverse effects of LMWH include:
- Bleeding
- Heparin-induced Thrombocytopenia
- Injection site reactions
- Osteoporosis [13].
Some other side effects are spontaneous fracture, hyperaldosteronism, and hypersensitivity reactions. Before prescribing this medication, healthcare providers must be knowledgeable of LMWH contraindications. It’s contraindicated in patients with hemorrhagic disorders, peptic ulcer disease, cerebral hemorrhage, trauma, and recent eye or nervous system surgeries.
Additionally, healthcare providers should caution when prescribing LMWH to patients with chronic kidney disease, as it increases the risk of accumulation in their system. Lower doses may be required for these individuals. A benefit of low molecular weight heparin when compared to unfractionated heparin is that the patient’s aPTT blood levels do not need to be monitored [13].

Vitamin K Dependent Antagonists
Vitamin K antagonists (VKAs) are a class of anticoagulant medications used in the prevention and treatment of blood clots. Warfarin is a commonly prescribed VKA and other less common VKAs are acenocoumarol, fluindione, and phenprocoumon [7].
Warfarin is approved for the treatment and prevention of pulmonary embolism, venous thrombosis, and thromboembolic complications of heart valve replacement and atrial fibrillation. It’s also used to reduce mortality risk after a myocardial infarction or stroke. Prevention of transient ischemic attack and stroke are additional off-label indications [11].
Vitamin K antagonists act by inhibiting the liver’s vitamin K epoxide reductase complex 1 (VKORC1). This reduces the amount of vitamin K reserves and therefore reduces the production of the body’s clotting factors that require vitamin K. Some clotting factors that are reduced include factors II, VII, IX, and X [7].
Vitamin K antagonists are available in oral form and are typically taken once daily in the afternoon or evening. Warfarin is rapidly absorbed, and onset of action is about 24 to 72 hours. The medication’s therapeutic effects aren’t normally seen until five to seven days after taking the medication. The typical starting dosage is 5 mg but might be less (2.5 mg) in patients who are elderly or who have liver disease [11].
Some common side effects of this class of medications include:
- Bleeding or bruising
- Nausea
- Vomiting
- Abdominal pain
- Altered sense of taste [11].
As VKAs alter the body’s ability to clot, it can cause more serious adverse effects, such as:
- Significant bleeding or hemorrhage
- Purple toe syndrome
- Warfarin-induced skin necrosis
- Calciphylaxis [11].
Warfarin and other VKAs have several contraindications such as gastrointestinal bleeding, cerebral aneurysm, dissecting aortic aneurysm, or other hemorrhagic conditions. Additionally, if the patient has had a recent nervous system, eye, or trauma surgery, then this medication should not be prescribed. Threatened abortion, malignant hypertension, and regional or lumbar anesthesia blocks are contraindications as well [11].
When prescribing VKAs, healthcare providers must order therapeutic monitoring and assess the patient’s prothrombin (PT) or international normalized ratio (INR). INR is usually the preferred method where a baseline level is initially drawn, and then subsequent levels are drawn within a week. The therapeutic range is dependent on the underlying medication condition, where the goal can range from an INR of 2 to 3 for most patients or from 2.5 to 3 for patients with a mechanical mitral valve.
Once the patient has reached their therapeutic goal, levels are typically drawn every four weeks unless there have been changes in their medications. Additionally, patients who take VKAs should have their hemoglobin and hematocrit levels and liver and kidney function checked at least every 6 months [11].

Direct Oral Anticoagulants
Direct oral anticoagulants (DOACs) are a class of anticoagulant medications mainly used to prevent thrombosis formation. There are two main classes of DOACs, which include direction thrombin inhibitors and direct factor Xa inhibitors [6].
Direct Thrombin Inhibitors
Direct thrombin inhibitors (DTIs) are used to treat and prevent thrombosis in patients with heparin-induced thrombocytopenia, acute coronary syndrome, or during percutaneous coronary intervention. Common names of direct thrombin inhibitors include argatroban, bivalirudin, fondaparinux, and dabigatran [9]. Additional off label uses may include anticoagulation during dialysis or renal replacement therapy, and it can be used as an alternative anticoagulant for patients who are resistant to heparin [10].
Direct thrombin inhibitors block coagulation activities that are involved in fibrin clot formation. There are two types of direct thrombin inhibitors, which are univalent DTIs that act by binding to the active site of thrombin, and bivalent DTIs that bind to two sites, the active thrombin site and exosite I.
As the thrombin pathways are blocked and cleavage of fibrinogen to fibrin is prevented, this ultimately inhibits clot formation and coagulation [9]. Some DTIs, like argatroban, are metabolized primarily via the cytochrome P450 enzyme [10].
This class of anticoagulant medications is typically available in intravenous form. However, it is also available in oral form, but dabigatran is the only available oral form. Starting dosages for DTIs depend on the medical condition being treated [9].
Some side effects of DTIs may include:
- Bleeding
- Gastrointestinal symptoms and bleeding
- Hypotension
- Dyspnea
- Fever
- Sepsis
[10]
When DTIs are used during PCI, some potential side effects are back pain, nausea, chest pain, and headache. Contraindications include increased bleeding, a history of medication hypersensitivity, lumbar puncture, and spinal anesthesia [10].
As most patients who are treated with DTIs have HIT, aPTT monitoring is common and the goal is 1.5 to 3 times the patient’s baseline. For patients who undergo PCI, ACT is used, and levels are obtained according to the hospital’s protocol or policy [10].
Direct Factor Xa Inhibitors
Direct factor Xa inhibitors are used to prevent and treat several blood clotting disorders. Examples of direct factor Xa inhibitors include apixaban, rivaroxaban, and edoxaban and they are only available in oral form [9].
These medications are often used to reduce the risk of stroke in patients with atrial fibrillation or other cardiac arrhythmias. Direct Xa inhibitors are also used to prevent and treat conditions like DVT or PE [1]. Rivaroxaban is approved for secondary prevention and adjunct therapy after acute coronary syndrome and peripheral artery disease [12].
Direct factor Xa inhibitors directly bind to factor Xa, preventing it from cleaving prothrombin to thrombin. This results in blocking the propagation phase of the coagulation cascade [9]. It is metabolized via the liver and by the CYP3A4/5 and CYP2J2 mechanisms [12].
Starting dosages of direct factor Xa inhibitors depend on the underlying medical condition. Rivaroxaban usually is started at 20mg daily for atrial fibrillation stroke prevention or 10mg daily for VTE prevention [12].
Some side effects of direct factor Xa inhibitors may include:
- Dizziness
- Hemorrhage
- Abdominal Pain
- Pruritis
- Nausea
[1] [12]
Direct factor Xa inhibitors have several drug interactions and thus, the healthcare provider must review any potential interactions before initiating this medication. Common drugs that have potential interactions are aspirin, ketoconazole, phenytoin, rifampin, and carbamazepine [1].
They are also contraindicated in patients with hepatic and renal impairment, antiphospholipid syndrome, and increased bleeding risk. Most have black box warnings of increased risk of thrombotic adverse events and spinal or epidural hematoma. They should also be avoided in patients who are pregnant or breastfeeding [12].
Although this class of medications does not require routine blood monitoring, the healthcare provider should consider obtaining baseline aPTT, PT, and kidney and liver function.
If the patient is scheduled for surgery with a moderately high risk of bleeding, direct factor Xa inhibitors should be held for at least 48 hours before the procedure [1].

Considerations for Prescribers
This section reviews potential considerations when prescribing anticoagulants.
When prescribing anticoagulant medications, healthcare providers must consider and review several factors. First, the route and dosage are typically determined by the setting, inpatient versus outpatient, if it’s being used for prevention or treatment, and the underlying medical condition.
Additionally, healthcare providers should strive to follow current guidelines, approved uses, and hospital protocols when initiating or adjusting these medications. Healthcare providers must review the patient’s medical history, baseline lab values, contraindications, and recommended therapeutic medication range as discussed above.
Low molecular weight heparin is often considered safe during pregnancy [13]. Certain anticoagulants, especially warfarin, should be avoided in patients who are elderly, prone to falls, or have reduced kidney function [11]. Oftentimes, anticoagulants are combined with antiplatelet medications to produce better therapeutic results in certain medical conditions [8].
Healthcare providers should also review the potential common and adverse side effects of anticoagulants with patients. Additionally, as bleeding is a serious adverse effect, they should review potential signs of bleeding, such as dizziness, uncontrolled bleeding to the skin, blood in the stool or urine, and other symptoms [15]. Patients should be instructed to seek immediate medical treatment if they experience any of these symptoms, fall at home, or have another traumatic injury.
In addition, they should be instructed on how to control bleeding when cuts occur to the skin [11]. A common side effect of LMWH is pain and bruising around the injection site. Therefore, patients should understand the importance of rotating injection sites and if side effects become a concern, then an oral alternative should be considered [13].
As periodic blood monitoring is required for many anticoagulants, such as INR, PT, or aPPT, the healthcare provider must review the importance of completing these labs and coming to their scheduled visits [15, 11]. If the patient is non-compliant with laboratory monitoring, then the healthcare provider should consider other alternatives, such are direct oral anticoagulants that do not require routine bloodwork or DTIs that have a wider therapeutic range [6] [9].
In addition, the healthcare provider must be knowledgeable about the potential drug interactions for each medication and dietary concern. For example, patients on vitamin K antagonists should reduce their intake of foods high in vitamin K since it counteracts the therapeutic effects of the medication. They should avoid foods rich in vitamin K, such as spinach, kale, and broccoli [7]. Co-administration of other anticoagulants, aspirin, and non-steroidal anti-inflammatory medications also increases bleeding risk [11].
Most anticoagulant medications can potentially cause toxicity and patients should seek emergency medical treatment. Therefore, healthcare providers must be aware of the signs and symptoms of toxicity and the reversal agent, or antidote, for each medication.
Protamine sulfate is the reversal agent for heparin and low molecular weight heparin. Protamine sulfate is administered via IV push and if administered too rapidly can lead to pulmonary edema, vasoconstriction, and pulmonary hypertension [15]. Vitamin K is the antidote for vitamin K antagonists [11]. Andexanet alfa is the reversal agent for direct factor Xa inhibitors and idarucizumab is approved for the reversal of dabigatran specifically [12].

Upcoming Research
This section reviews upcoming research and medications for anticoagulant treatment.
There have been many new anticoagulant medications introduced over the past several years and research continues to evolve for this type of medication. More recently, a newer class of anticoagulant medications called anti-factor XI and Xia inhibitors, affect the factor XI pathway for clot formation. However, it’s still being researched and there are ongoing clinical trials [3].
Moreover, in November 2023, the American Heart Association released promising information about abelacimab, a monoclonal antibody that acts as a factor XI inhibitor, which has been shown to reduce stroke risk in patients with atrial fibrillation. The same report stated that bleeding risk was reduced by more than 60% while taking this medication [2].
Potential factor VII and VIII inhibitors are also being researched [16].

Conclusion
Anticoagulants are typically indicated for the prevention and treatment of blood clotting conditions, including deep vein thrombosis and pulmonary embolism. However, they have several additional approved and off-label uses. Healthcare providers should understand the pharmacokinetics, potential side effects, and contraindications when selecting an anticoagulant. They should also follow current clinical guidelines and their facility’s protocols for a more evidence-based approach.

SNRIs for Depression
Introduction
Depression can significantly interfere with daily activities and diminish quality of life among patients who experience it. Major depressive disorder (MDD) is one of the leading causes of the burden for worldwide diseases (5). At the present stage, the first-line treatment of MDD is selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). Research has found that SNRIs showed faster antidepressant effects than SSRIs (5).
The serotonin norepinephrine reuptake inhibitors (SNRIs) are a family of antidepressants that inhibit the reuptake of both serotonin and norepinephrine; however, it is important to recognize the differences among each specific drug in this class. In this course, we will examine pharmacological properties, clinical indications, mechanism of action, metabolism and excretion, dosing schedules, side effects, and warnings of each SNRI currently approved by the United States Food and Drug Administration (FDA) for the treatment of depression.
Forms and Symptoms of Depression
Depression can have crippling effects. Research suggests that genetic, biological, environmental, and psychological factors play a role in depression (7). Depression can be present with other comorbidities, such as mental disorders, diabetes, cancer, heart disease, and chronic pain. Depression can make these conditions worse, and vice versa. Certain medications have been shown to increase depressive symptoms.
Common forms of depression are: (7)
- Major depression - which includes symptoms of depression most of the time for at least two weeks that regularly interfere with work, sleep, eating, and quality of life.
- Persistent depressive disorder (dysthymia), which often includes less severe symptoms of depression that last much longer, typically for at least two years.
- Perinatal depression - occurs when a woman experiences major depression during pregnancy or after delivery (postpartum depression).
- Seasonal affective disorder – impacted by change in seasons, typically starting in late fall and early winter and improving during spring and summer.
- Depression with symptoms of psychosis - a severe form of depression in which the patient experiences psychosis symptoms, such as delusions or hallucinations
Common symptoms of depression include:
- Persistent sad, anxious, or “empty” mood
- Feelings of hopelessness
- Irritability, frustration‚ or restlessness
- Feelings of guilt, worthlessness, or helplessness
- Loss of interest or pleasure in hobbies or activities once enjoyed
- Fatigue or lack of energy
- Aches, musculoskeletal pain, or headaches without injury or obvious causation, and do not improve with medication.
- Gastrointestinal issues
- Difficulty concentrating, remembering, or making decisions
- Poor sleeping patterns
- Changes in appetite
- Suicide attempts or thoughts of death or suicide

- Are you aware of certain biological, environmental, or psychological factors that play a role in depression?
- How would you describe the difference between occasional sadness and depression?
- Can you name common symptoms of depression?
- Which drug class has shown faster antidepressant effects in studies, SSRIs or SNRIs?
Pharmacokinetics of SNRIs
The major mechanism of action of SNRIs is the inhibition of presynaptic neuronal uptake of 5-HT (serotonin) and norepinephrine after release from the synaptic cleft (3). Blocking the reuptake prolongs the presence of monoamines in the synaptic cleft within the central nervous system (CNS). This causes an increase in postsynaptic receptor stimulation and additional post synaptic neuronal transmission (3).
Serotonin
Serotonin, or 5-hydroxytryptamine (5-HT), is a neurotransmitter that has an important role in regulating various activities, including behavior, mood, memory, and gastrointestinal homeostasis (1). It is often referred to as the “feel good hormone” and delivers messages between brain cells, contributing to well-being, mood, appetite, social behavior, as well as helping to regulate the body’s sleep-wake cycle.
Serotonin is synthesized in the raphe nuclei of the brainstem and the enterochromaffin cells of the intestinal mucosa (1). Serotonin is a primary treatment target for major depressive disorder (MDD), post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), and anxiety disorders.
Norepinephrine
Norepinephrine, also known as noradrenaline, is a neurotransmitter in the brain that plays an essential role in the regulation of arousal, attention, cognitive function, and stress reactions. It also functions as a hormone peripherally as part of the sympathetic nervous system in the “fight or flight” response.
During states of stress or anxiety, norepinephrine and epinephrine are released and bind to adrenergic receptors throughout the body which exert effects such as dilating pupils and bronchioles, increasing heart rate and constricting blood vessels, increasing renin secretion from the kidneys, and inhibiting peristalsis.
It works closely with dopamine and serotonin systems and is thought to help mobilize the brain for action, increasing alertness, focus, and the retrieval of memory (4).
The increased availability of serotonin and norepinephrine in the nerve synapse means that information can be transmitted easier from one nerve to another.
There are currently five SNRIs approved by the FDA for use in the U.S.:
- Venlafaxine (Effexor XR)
- Duloxetine (Cymbalta, Irenka)
- Desvenlafaxine (Pristiq, Khedezla)
- Levomilnacipran (Fetzima)
- Milnacipran (Savella)
- Milnacipran (Savella TM) is not approved by the FDA to treat depression, but rather only fibromyalgia. For this reason, this course will not review this SNRI.
As mentioned, all SNRIs regulate serotonin and norepinephrine, but there are subtle differences in how much absorption they prevent and the side effects of each type.
Self Quiz

- Do all SNRIs have the same uses?
- Can you define serotonin and norepinephrine in your own words?
- Are you familiar with these SNRIs? If so, have you known patients who have benefited from use?
- How would you describe the relationship between sleep cycles, nutrition, and mood?
Venlafaxine
Venlafaxine (Effexor ™) is approved by the FDA and was the first SNRI approved in the U.S. It is available in an extended-release formula and works by regulating levels of serotonin and norepinephrine.
Uses
- Major depressive disorder
- Generalized anxiety disorder
- Social anxiety disorder
- Panic disorder
Mechanism of Action
Venlafaxine increases serotonin, norepinephrine, and dopamine in the brain by blocking transport proteins and preventing their reuptake at the presynaptic terminal (10). This action leads to more neurotransmitters available at the synapse, which ultimately increases the stimulation of postsynaptic receptors.
Venlafaxine is a bicyclic phenylethylamine compound; it is a more potent inhibitor of serotonin reuptake than norepinephrine reuptake (8). Venlafaxine acts as a selective serotonin reuptake inhibitor at 75 mg, but when a higher dose is given, such as 225 mg/day, it has significant effects on the norepinephrine transporter as well (10). Venlafaxine does not have MAO-inhibitory properties.
Pharmacodynamics
The pharmacodynamics of venlafaxine is as follows: (9)
Absorption: 92-100% absorbed after oral administration.
Distribution: Extensive distribution into body tissues.
Metabolism and Excretion: Extensively metabolized in first pass through the liver. 5% of venlafaxine is excreted unchanged in urine; 30% of the active metabolite is excreted in urine.
Half-life: 3-5 hr.; ODV: 9-11 hr.
Contraindications
- Hypersensitivity
- Precaution advised for use in patients with:
- Cardiovascular disease
- Hepatic or renal impairment
- History of seizures or neurologic impairment
- History of mania
- History of drug abuse
- Angle-closure glaucoma
Obstetrics (OB): Use during pregnancy only if risks are closely examined. There is a potential for discontinuation syndrome or toxicity in the neonate when venlafaxine is taken during the 3rd trimester (9). Venlafaxine is a category C pregnancy drug and can potentially pass into breast milk (8).
Venlafaxine is contraindicated if it causes worsening suicidal ideation, depression, anxiety, and psychosis. Precaution is needed for patients with heart failure patients, hyperthyroidism, and those with recent myocardial infarctions, as it can raise blood pressure and increase heart rate. Venlafaxine raises the risk of seizures, and prescribers should avoid the drug in patients with a seizure disorder (8).
Adverse Reactions / Side Effects
Adverse reactions / side effects of venlafaxine include: (10)
CV: Chest pain, hypertension, palpitations, tachycardia.
Neuro: Abnormal dreams, anxiety, dizziness, headache, insomnia, nervousness, paresthesia.
Dermatology: ecchymoses, itching, photosensitivity, skin rash.
EENT: rhinitis, visual disturbances.
GI: abdominal pain, altered taste, anorexia, constipation, diarrhea, dry mouth, dyspepsia, nausea, vomiting, weight loss.
GU: Decreased libido, erectile dysfunction, urinary frequency, urinary retention.
Hematological: Bleeding.
Serotonin syndrome – a condition of building up high levels of serotonin in the body due to medication use. Although rare, serotonin syndrome is a very serious condition that has a high mortality rate (5). Signs of serotonin syndrome include tachycardia, sialorrhea (excessive saliva production), hyperactive bowel sounds, mydriasis (sustained dilated pupils), hyperthermia, and diaphoresis (6). This condition is caused by combining monoamine oxidase inhibitors, tricyclic antidepressants, triptans, additional serotonin receptor modulators, or over-the-counter drugs such as St. John's Wort (6).
If a clinician is suspecting serotonin syndrome, the Sternbach and Hunter criteria can be useful to help arrive at a definitive diagnosis.
Drug-Drug Interactions
- Concurrent use with MAO inhibitors or serotonergic neurotransmitter systems, including tricyclic antidepressants, fentanyl, buspirone, tramadol, amphetamines, and triptans, may increase the risk of serotonin syndrome (9).
- Concurrent use of NSAIDs, aspirin, warfarin or other drugs that affect coagulation may increase the risk of bleeding.
- Concurrent use of other medications that may increase risk of hypertension.
- Concurrent use with alcohol may cause a rapid release of drug and should be avoided.
- Monitor closely for any changes in behavior that could indicate the emergence or worsening of suicidal thoughts or behavior or depression.
Route and Dosage in Depression
PO (Adults): Tablets: 75 mg/day in 2-3 divided doses; may increase by up to 75 mg per day every 4 days, up to 225 mg/day. Do not exceed 375 mg per day in 3 divided doses.
Extended-release capsules: 75 mg once daily (some patients may be started at 37.5 mg once daily) for 4-7 days; may increase by up to 75 mg/day at intervals for no less than 4 days (not to exceed 225 mg/day).
ALERT: US Boxed Warning
Antidepressants increased the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders (10). Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults older than 24 years old (10).
Venlafaxine is not approved for use in pediatric patients.

Duloxetine
Duloxetine (Cymbalta ™) has the most FDA-approved uses of any SNRI, and, unlike Venlafaxine, is proven to be effective in the treatment of other conditions, such as neuropathy, fibromyalgia, and osteoarthritis (9).
Drug Class
Selective Serotonin/Norepinephrine Reuptake Inhibitors
Uses
Duloxetine is used for the following conditions: (9)
- Major depressive disorder
- Diabetic peripheral neuropathic pain
- Generalized anxiety disorder
- Chronic musculoskeletal pain (including chronic lower back pain and chronic pain from osteoarthritis)
- Fibromyalgia
Mechanism of Action
Duloxetine inhibits serotonin and norepinephrine reuptake, and also enhances dopamine levels within the prefrontal cortex. This increase in dopamine levels involve the inhibition of norepinephrine transporters, which are particularly attracted to dopamine, making it effective in transporting dopamine and norepinephrine (2). Essentially, inhibition of norepinephrine transporters can cause an increase in dopamine.
The secondary mechanisms of action, in increasing dopamine, is helpful in pain reduction. This occurs due to increased activity of noradrenergic and serotonergic neurons in the descending spinal pathway on the dorsal horn and suppression of excessive input from reaching the brain (2). The perception of pain can be reduced as these signals are interrupted.
Pharmacokinetics
Absorption: Well-absorbed following oral administration.
Distribution: Unknown.
Protein Binding: >90%.
Metabolism and Excretion: Primarily metabolized in the liver via the CYP2D6 and CYP1A2 isoenzymes. Excretion: Fecal is 20%; renal is 70% as metabolites.
Half-life: 12 hr.
Time/Action Profile (Plasma Concentrations):
ROUTE | ONSET | PEAK | DURATION |
PO | Unknown | 6 hr. | 12 hr. |
Contraindications:
Contraindications in the use of duloxetine include: (9)
- Hypersensitivity
- Concurrent use of MAO inhibitors or MAO-like drugs (linezolid or methylene blue).
- Severe renal impairment (CCr <30 mL/min).
- Hepatic impairment or substantial alcohol use (increased risk of hepatitis).
Use cautiously in:
- History of suicide attempt or ideation.
- History of mania (may activate mania/hypomania).
- History of seizure disorder.
- Diabetes (may worsen glycemic control).
- Angle-closure glaucoma.
OB/ Lactation: Use while pregnant or breastfeeding only if potential maternal benefit justifies potential risk to infant.
Geriatric Precaution: Appears on Beers list. May worsen or cause syndrome of inappropriate antidiuretic hormone (SIADH) secretion and/or hyponatremia in older adults; closely monitor sodium concentrations.
Adverse Reactions / Side Effects
CV: Hypertension, orthostatic hypotension.
EENT: Increased intraocular pressure, blurred vision.
Endocrine: SIADH.
Fluids and Electrolytes: Hyponatremia.
GI: Decreased appetite, constipation, dry mouth, nausea.
GU: Dysuria.
Neurological: Drowsiness, fatigue, insomnia.
Drug-Drug Interactions
- Concurrent use with MAO inhibitors is contraindicated; wait at least 14 days following discontinuation of MAO inhibitor before initiation of levomilnacipran (9). Concurrent use with MAO-inhibitor like drugs, serotonergic neurotransmitter systems, including tricyclic antidepressants, SNRIs, fentanyl, buspirone, tramadol, amphetamines, and triptans may increase the risk of serotonin syndrome (9).
- Increased risk of hepatotoxicity in patients who abuse alcohol or have alcohol use disorder (9).
- Increased risk of serious arrhythmias when used with thioridazine; avoid concurrent use (9).
- Concurrent use of NSAIDs, aspirin, warfarin or other drugs that affect coagulation may increase the risk of bleeding.
- Concurrent use of other medications that may increase risk of hypertension.
- Concurrent use with alcohol may cause a rapid release of drug and should be avoided.
- Monitor closely for any changes in behavior that could indicate the emergence or worsening of suicidal thoughts or behavior or depression.
Route and Dosage in Depression
PO (Adults): 40-60 mg/day (as 20 mg or 30 mg twice daily or as 60 mg once daily) as initial therapy, then 60 mg once daily as maintenance therapy (9).

Desvenlafaxine
Desvenlafaxine (Pristiq ™) received approval from the FDA in 2008. The drug is similar to Venlafaxine structurally and 10 times more potent in inhibiting serotonin reabsorbing than norepinephrine (6). It has been observed weakly blocking dopamine reuptake, similar to Venlafaxine and Duloxetine.
Uses
Desvenlafaxine is an antidepressant that is an FDA-approved drug to treat major depressive disorder in adults. For healthy women who have contraindications to estrogen, desvenlafaxine has an off-label use to treat hot flashes during menopause (6).
Mechanisms of Actions
Desvenlafaxine is the primary active metabolite of venlafaxine. Therefore, the two agents are structurally similar in that they both contain two chemical rings that are not next to each other. In vitro studies have shown that desvenlafaxine is ten times more selective for serotonin than for norepinephrine, making it similar to the drug duloxetine (6).
Pharmacokinetics
Absorption: 80% absorbed following oral administration.
Distribution: Widely distributed to tissues.
Metabolism and Excretion: 55% metabolized by the liver, 45% excreted unchanged in urine.

Contraindications/Precautions
- Hypersensitivity to venlafaxine or desvenlafaxine.
- Concurrent use of MAO inhibitors or MAO-like drugs (linezolid or methylene blue).
- Should not be used concurrently with venlafaxine.
Use cautiously in:
- Untreated cerebrovascular or cardiovascular disease, including untreated hypertension (control BP before initiating therapy).
- Bipolar disorder (may activate mania/hypomania).
- Moderate or severe renal impairment.
- History of seizures or neurologic impairment.
- Moderate or severe hepatic impairment.
- Angle-closure glaucoma.
OB: Safety is not established in pregnancy. Desvenlafaxine is excreted into breast milk, with one study reporting that peak levels are 3.3 hours after a dose (6).
Adverse Reactions / Side Effects
There is a broad range of general adverse effects that patients have reported with desvenlafaxine. A study comparing desvenlafaxine to a placebo in treating major depressive disorder in adolescents noted the most common side effects to be abdominal pain, decreased appetite, headache, and nausea (6).
Less common side effects were diarrhea, dizziness, and cough.
Abruptly stopping the use of desvenlafaxine can cause irritability, nausea, and headaches (6). Gradually tapering the medication is recommended to avoid such side effects.
Drug-Drug Interactions
- The concurrent use of all SNRIs and MAO inhibitors may result in serious and potentially fatal reactions (it may increase the risk of serotonin syndrome) (9). A period of at least two weeks is recommended between stopping MAO inhibitors and initiating venlafaxine (9).
- Concurrent use of NSAIDs, aspirin, warfarin or other drugs that affect coagulation may increase the risk of bleeding.
- Concurrent use of other medications that may increase the risk of hypertension.
- Concurrent use with alcohol may cause a rapid release of drug and should be avoided.
- Monitor closely for any changes in behavior that could indicate the emergence or worsening of suicidal thoughts or behavior or depression.
Increased risk of hepatotoxicity in patients who abuse alcohol or have alcohol use disorder (9).
Increased risk of serious arrhythmias when used with thioridazine; avoid concurrent use (9).
Route and Dosage in Depression
PO (Adults): 50 mg once daily (range = 50-400 mg/day).
Renal Impairment:
PO (Adults): CCr 30-50 mL/min: 50 mg once daily; CCr <30 mL/min: 50 mg every other day or 25 mg once daily.

Levomilnacipran
Levomilnacipran (Fetzima ™) is the most recent medication approved for treating major depression.
Levomilnacipran is different from other SNRIs because it has greater inhibition of norepinephrine than serotonin; essentially, it has twice the potency of norepinephrine reuptake inhibition compared to serotonin (3). The more recent FDA approval and relatively lower number of prescriptions may be contributing factors to an overall low volume of research and evidence on this drug.
Levomilnacipran has a one-a-day extended-release form, which makes it easier for patients to stick to its regimen. The drug has no effect on dopamine and affects reuptake inhibition of serotonin and norepinephrine steadily at any dose (3).
Uses
- Major Depressive Disorder
Mechanisms of Actions
Levomilnacipran enhances the amount of serotonin (5-HT) and norepinephrine (NE) activity in the central nervous system by inhibition of reuptake at 5-HT and NE transporters (9). Levomilnacipran has shown to be a more potent inhibitor of NE versus 5-HT transporter (9).
Pharmacokinetics
Absorption: Well-absorbed (92%) following oral administration.
Metabolism and Excretion: Primarily metabolized in the liver via the CYP3A4 isoenzyme. 58% eliminated unchanged in urine; 42% metabolized; metabolites are renally eliminated.

- Bipolar disorder (may activate mania/hypomania).
- Renal impairment.
OB: Use only if potential maternal benefit justifies potential fetal risk.
Geriatric: Consider age-related decrease in renal function, chronic disease state and concurrent drug therapy in older adults; increased risk of hyponatremia.
Adverse Reactions/Side Effects
CV: Hypertension, hypotension, palpitations, tachycardia.
Dermatology: Hyperhidrosis (excessive sweating), rash.
EENT: Mydriasis.
Fluids and Electrolytes: Hyponatremia (in association with syndrome of inappropriate antidiuretic hormone [SIADH]).

Nursing Considerations
It is vital to recognize how each patient is unique and different in their journey of depression treatment. Nurses play a key role in assessing and providing advocacy for these patients.
The following are important nursing considerations:
- Thorough and focused mental status assessment
- Assess level of consciousness and orientation, appearance and general behavior, speech, motor activity, affect and mood, thought and perception, attitude and insight, and cognitive abilities.
- Assess status and mood changes.
- Assess suicidal tendencies, especially in early beginning of SNRI (9).
- Monitor BP before and periodically during therapy. Sustained hypertension may be dose-related; decrease dose or discontinue therapy if this occurs.
- Assess for serotonin syndrome.
- Provide patient education on medication use, dosage, and side effects. Provide patient education on support and resources available.
Nursing Diagnosis: Disturbed Thought Processes
Nursing Diagnosis: Ineffective Coping
Lab Assessments
Monitor CBC with differential and platelet count periodically during SNRI therapy. These medications can cause anemia, leukocytosis, leukopenia, thrombocytopenia, basophilia, and eosinophilia (9).
May cause an increase in serum alkaline phosphatase, bilirubin, AST, ALT, BUN, and creatinine, and serum cholesterol.
SNRIs can also cause electrolyte abnormalities (hyperglycemia or hypoglycemia, hyperkalemia or hypokalemia, hyperuricemia, hyperphosphatemia or hypophosphatemia, and hyponatremia).
Conclusion
SNRIs are an effective method of treatment for those suffering from depression. The effectiveness of SNRIs is dependent on a variety of factors like dosage and time spent in the body. Although the mechanisms of actions and makeup of SNRIs are consistent, each drug has differences on how much reuptake they prevent and the side effects of each type. Prescribers must be aware of these differences, the uses, mechanisms of action, side effects, and warnings.
Corticosteroid Therapy
Introduction
When many people hear of steroids, they may think of athletes. However, the steroids that some athletes misuse to enhance their strength and training abilities are not the same as those administered for allergic reactions and some inflammatory conditions. The steroids used by some athletes are called anabolic steroids. The steroids used for the treatment of disease are called corticosteroids.
Steroids are hormones naturally produced in the body (made from cholesterol) to regulate the function of various bodily systems [2]. Some steroid hormones are produced by the adrenal glands of the endocrine system (a set of two glands that rest atop the kidneys). The adrenal glands produce the hormone types: glucocorticoids, mineralocorticoids, and adrenal androgens [2]. Corticosteroid medication mimics glucocorticoids, more specifically a glucocorticoid called “cortisol.”
The Immune System
Corticosteroids are well-known for increasing a patient’s risk for infection. This is due to the medication’s effect on the immune system, particularly its anti-inflammatory properties. It is important to have a clear understanding of how the immune system works as well as the inflammatory process that takes place when a foreign pathogen enters the body.
How Does the Immune System Work?
In a typical immune system the immune system is triggered by an antigen – a marker in the body that alerts cells of the immune system that there’s a foreign invader present, like a pathogen or foreign object. Subsequently, a series of events follows. Like in a war, the body rounds up the first line of defense soldiers to fight the pathogen.
These include [11]:
- Proteins (called “the inflammasome”) to active inflammatory responses.
- Macrophages to engulf and digest pathogens.
- Neutrophils to help kill pathogens and rid of the leftover debris.
- Endothelial cells to help rid of the dead pathogens/debris.
The influx of these cells to the site of injury or infection is the beginning of inflammation.
What is Inflammation?
Inflammation is more than just “swelling.” Inflammation is a process in which a cascade of events occurs to help the immune system fight against pathogens and foreign bodies. The inflammatory process encompasses a variety of signs/symptoms including redness, warmth, swelling, and drainage [11].
For example, when a person sustains a traumatic injury to the skin causing an open wound, the accompanying redness (or erythema) is caused by a rush of red blood cells through the site [5]. The dilation of the blood vessels is what causes this “rush” of cells. The increased blood flow also causes the localized warmth that typically occurs. Blood vessel dilation is responsible for the associated swelling as well. The pus that forms is a combination of fluid, dead immune/pathogen cells, and debris from the fight, essentially, the “casualties at war” that must be removed from the body [5].
As with fever, inflammation aids in the fight against pathogens and therefore should not be inhibited unless it is likely to be damaging or fatal in and of itself. [11]. This inflammatory process is acute in nature, and typically goes away on its own or with the help of medication. While acute inflammation from a normal immune response is natural and beneficial, chronic inflammation is harmful and can lead to permanent damage of tissues and body systems.
Chronic inflammation can be seen in conditions including inflammatory bowel disease, cancer, heart disease, and autoimmune disorders like rheumatoid arthritis, multiple sclerosis, and systemic lupus erythematosus [11]. Chronic inflammation is typically caused by an overactive immune system or autoimmune disease (when the immune system mistakenly attacks normal tissues). In cases like these, inhibiting the inflammatory process by suppressing the immune system is most beneficial. This is where corticosteroids come into play.

Corticosteroids: The Basics
Corticosteroids are a group of steroidal therapy medications that are often the go-to for reducing inflammation in the body. Once referred to as “a miracle drug,” these medications are helpful in the treatment of acute and chronic inflammatory conditions and autoimmune diseases.
Corticosteroids are also useful in emergency situations, for example during asthma attacks or allergic reactions – when the inflammation is life-threatening. Corticosteroids are synthetically formulated to mimic the hormone cortisol.
What is Cortisol?
As mentioned earlier, the adrenal glands of the endocrine system produce three different types of steroid hormones, one of which is glucocorticoids. Cortisol is a major glucocorticoid hormone.
There are two major structures of the adrenal glands – the outer layer (cortex) and inner portion (medulla) – each producing its own hormones. The outer layer (cortex) produces cortisol, hence the name “corticosteroid” [6].
Cortisol levels in the body rise when a person is stressed [2]. This hormone helps to regulate metabolism, growth, reproduction, and the immune system [2]. Cortisol also aids in cardiovascular function by making blood vessels more sensitive to natural vasoconstrictors in the body (like adrenaline) [2].
How Do Corticosteroids Work?
Corticosteroids work by suppressing the immune system which in turn reduces inflammation. In patients with an overactive immune system or acute flareups from a triggering agent, the inflammation can cause troubling symptoms, become prolonged, and spread to other areas within the body. If left untreated, inflammation can lead to tissue scarring (or damage to affected structures) and loss of bodily functions [11].
The challenge with administering corticosteroids to suppress an overactive immune system is balancing the benefits of inflammatory symptom relief and the risks of infection due to the resulting underactivity of the immune system. In this case, clinicians are encouraged to start with the lowest therapeutic dose possible, carefully monitor its use in patients with infections, and ensure that the benefits exceed the risks [6].
Corticosteroids also stop the body from producing its own natural cortisol. In a sense, a course of corticosteroids gives the adrenal glands a break. In a short course of corticosteroids, once the medication is discontinued, the adrenal glands can start back releasing cortisol. However, the adrenal glands do not resume releasing cortisol right away and need time to start working again.
This is why corticosteroids (oral and parenteral forms) should not be stopped abruptly when taken for more than about two weeks [6]. If stopped abruptly, patients may develop adrenal insufficiency during this period, which can be life-threatening.

Corticosteroid Pharmacology
Common corticosteroid formulations include intravenous (IV), intramuscular (IM), intra-articular (injected directly into a joint), oral, inhaled, intranasal (nasal spray), topical, ophthalmic (eye drops), and otic (ear canal). The increased risk of infection is most associated with systemic formulations (oral and parenteral).
The following sections will cover the pharmacology of systemic corticosteroids, including indications, mechanisms of action, pharmacokinetics, precautions, adverse effects, drug interactions, and warnings [7].
Indications
Corticosteroids are useful in the treatment of many medical conditions. Some indications for corticosteroids among adults include the following diseases, conditions, and situations (maybe drug- or route-specific) [6][7].
Allergic Reactions
Corticosteroids are well-known for treating mild to severe allergic reactions. These include anaphylaxis, angioedema, and laryngeal edema (non-infectious). Others include hypersensitivity reactions to medications or food, severe seasonal allergies (like allergic rhinitis), contact dermatitis (or rash), and itching.
Autoimmune Diseases
Corticosteroids are used to treat autoimmune disorders including systemic lupus erythematosus, Crohn’s disease, rheumatoid arthritis, and plaque psoriasis. Others include autoimmune hepatitis, hemolytic anemia, celiac disease (gluten intolerance), sarcoidosis (marked by lumps of inflammatory cells throughout the body) and myasthenia gravis (marked by weakness in voluntary muscles).
Pulmonary Exacerbations
Corticosteroids are useful in the treatment of exacerbations from asthma and chronic obstructive pulmonary disease (COPD).
Adrenal Insufficiency
Corticosteroids may be used to treat both primary and secondary adrenocortical insufficiency. This includes Addison’s disease, congenital adrenal hyperplasia, and adrenogenital syndrome.
Inflammatory Bowel Disease
Inflammatory bowel disease, such as the aforementioned Crohn’s disease, and ulcerative colitis may be treated with corticosteroids.
Neuro/Musculoskeletal Disorders
Corticosteroids are used in the treatment of ankylosing spondylitis (chronic inflammation of spinal joints), bursitis, polymyalgia rheumatica (marked by muscle pain and stiffness), osteoarthritis, and psoriatic arthritis. Corticosteroids can also treat neurological conditions like multiple sclerosis and Bell’s palsy (facial paralysis, often temporary).
Inflammatory Eye Conditions
Corticosteroids are useful in the systemic treatment of inflammatory ophthalmic conditions including optic neuritis, allergic conjunctivitis, and other conditions that cause inflammation of various structures of the eye.
Organ Transplant Rejection Prophylaxis
Renal transplant guidelines recommend corticosteroids in combination with other medications to prevent kidney rejection after transplantation (called induction therapy or immunosuppressant therapy). Corticosteroids are also indicated for heart and liver transplant rejection prophylaxis.
Cancer
Corticosteroids may be used for the palliative treatment of cancers including multiple myeloma and chronic lymphocytic leukemia (CLL). They may also be used to treat Hodgkin lymphoma (in conjunction with cancer medications), aggressive non-Hodgkin lymphoma, peripheral T-cell lymphoma, and neoplastic-associated hypercalcemia.
COVID-19
Although still in the investigative stages, the World Health Organization (WHO) recommends systemic corticosteroids as an adjunctive treatment for severe COVID-19 [6][13].

- What is the most common indication for corticosteroid therapy you have witnessed in your practice?
- Have you ever prescribed/administered corticosteroids for prophylaxis treatment alone?
- Can you think of ways to minimize the severity of adverse effects of corticosteroid therapy among patients most at risk?
Mechanism of Action
As already mentioned, corticosteroids suppress the immune system. This is done by preventing protein synthesis in certain cells of the immune system (like macrophages and neutrophils), ultimately inhibiting their fighting potential [6][11]. More specifically, corticosteroids repress the activity of DNA within the immune cell – an activity that would otherwise serve as the beginning of protein synthesis.
Within immune cells, DNA sends messages to protein-making structures within the cell that prompts them to start making protein. However, the message must be “translated” or “decoded” (transcription) first before the structures can “understand” what to do [6][12]. Messenger RNA (mRNA) is the transcribed version of DNA. Corticosteroids work by making it difficult for DNA to be transcribed into mRNA.
Pharmacokinetics
The pharmacokinetics of corticosteroids differ based on drug type and route. The following is the pharmacokinetics of three common systemic corticosteroid drugs: prednisone, methylprednisolone, and dexamethasone [6].
Prednisone
Prednisone comes in oral forms, both immediate-release (IR) and delayed-release. Prednisone IR is quickly absorbed in the gastrointestinal (GI) tract with a peak effect after one to two hours. Delayed-release tablets are released four hours after ingestion and peak after about six hours. Prednisone is metabolized by the liver and excreted by the kidneys.
Methylprednisolone
Methylprednisolone is rapidly absorbed orally and peaks within one to two hours. After IV administration, effects can occur within one hour with nearly complete excretion in 12 hours. When given as an injection in the joint, methylprednisolone absorption can occur over several days. This medication is distributed into various organs and body structures including the kidneys, intestines, skin, liver, and muscle. Methylprednisolone is metabolized by the liver and excreted by the kidneys.
Dexamethasone
Oral dexamethasone peaks in one to two hours. Absorption times for parenteral forms depends on the dosage and indication. For example, in patients with cerebral edema, treatment response from an IV dose of dexamethasone followed by an IM dose occurs in 12 to 24 hours [1]. Dexamethasone is rapidly distributed into the skin, intestines, liver, muscle, and kidneys. As with prednisone and methylprednisolone, this medication is metabolized by the liver and excreted by the kidneys.

Contraindications and Precautions
Clinicians should not prescribe/administer prednisone to patients with an allergy to the drug or any components of its formulation. Precautions should be taken in patients with an allergy to other corticosteroids as cross-sensitivity can occur. Clinicians should also be aware that high-dose systemic corticosteroids place patients at risk for immunosuppression, especially when prescribed/administered with other immunosuppressant medications.
Although carrying a lower risk, moderate-dose and low-dose corticosteroid preparations should be monitored as well. Clinicians should avoid prescribing/administering these medications to patients with fungal or bacterial infections that are not well controlled with anti-infective medications.
Pregnancy and Breastfeeding Precautions
While corticosteroids are not contraindicated for pregnant or breastfeeding patients, clinicians have reason to be cautious when prescribing/administering these medications [6]. The following are precautions for pregnant and breastfeeding patients.
Pregnancy
If corticosteroids must be prescribed/administered during pregnancy, precaution should be taken as these medications cross the placenta and may be harmful to the fetus/infant (may cause adrenal insufficiency in the infant). Although the risks are small and inconsistent, oral or facial clefts (like cleft palate) may occur if systemic corticosteroids are prescribed/administered during the first trimester.
Breastfeeding
Corticosteroids are distributed into breastmilk. While no reported side effects have been reported in breast-fed infants, lower doses are recommended as high doses may cause problems with the infant’s growth and development. Corticosteroids can interfere with the infant’s ability to produce their own glucocorticoid hormones. With prednisone in particular, peak concentrations in breastmilk occur in about one hour after the dose is taken and it is recommended for patients to avoid breastfeeding during this time. However, the total daily dose of prednisone reaching the infant has been shown to be approximately 0.1% of the mother’s total daily dose [6].

- Have you ever witnessed a patient have a severe allergic reaction to a corticosteroid? If so, what was the treatment/anecdote?
- Have you ever been in a situation in which you had no choice but to prescribe/administer corticosteroids to a patient who was pregnant?
Adverse Effects
Corticosteroids given systemically can affect multiple body systems, particularly with prolonged use. Short-term use in high doses typically does not cause adverse effects [6]. Adverse effects of corticosteroids can be as mild as a rash to as severe as psychosis or a ruptured heart wall.
The following are adverse effects categorized by body systems [6].
Neurological
Corticosteroids may increase intracranial and intraocular pressure which can lead to optic nerve damage and visual impairments. These medications can also lower seizure thresholds. Other neurological findings include headache, vertigo, and peripheral neuropathy.
Pulmonary
Corticosteroids can reactivate tuberculosis (TB) in patients who have a history of active TB.
Cardiovascular
Sodium retention, edema, and low potassium may occur in patients with high blood pressure or congestive heart failure (can also occur with renal failure/insufficiency). Left ventricular free-wall rupture can occur in patients with a recent myocardial infarction. Corticosteroids may also exacerbate arrhythmias and cause blood clots which may lead to a stroke.
Endocrine
Corticosteroids are known to decrease glucose tolerance and raise blood glucose levels. This can aggravate existing diabetes mellitus. Hypothalamic-pituitary-adrenal (HPA) suppression or signs/symptoms of Cushing’s syndrome (marked by high cortisol levels) can also occur with prolonged systemic use.
Gastrointestinal/Genitourinary
Corticosteroids can increase the risk of GI perforation and should therefore be monitored in patients with peptic ulcer disease, diverticulitis, or GI abscess. Additionally, esophageal ulcers and GI bleed may occur with use. Corticosteroids may cause weight loss, but can stimulate the appetite as well, leading to weight gain conversely. Menstrual irregularity may occur as well.
Musculoskeletal
Osteopenia (loss of bone density) and osteoporosis (more severe bone loss) can occur due to decreased bone formation, increased bone resorption, and inhibition of osteoblast function. Bone fractures (primarily in elderly patients) can occur as well. Acute generalized myopathy leading to quadriparesis (weakness in all extremities) may occur in patients with neuromuscular disease or those receiving neuroblocking medications. Muscle pain and waste can also occur due to protein depletion.
Skin
Corticosteroids may cause impaired wound healing due to protein depletion. Sweating, abnormal hair growth, and striae (stretch marks) can also occur with use. While corticosteroids may be useful in the treatment of rashes and itching, they can cause these symptoms as well.
Psychiatric
Psychiatric problems can occur with corticosteroid use, including euphoria, severe depression, anxiety, hallucinations, psychosis, personality changes, and withdrawn behavior. Patients may also experience insomnia, impaired cognition, mood swings, irritability, and restlessness.
Laboratory Changes
A common lab finding with corticosteroid use is leukocytosis (without an infectious or inflammatory cause). It is important for clinicians to differentiate between infectious and corticosteroid-related leukocytosis. Other lab findings may include low neutrophil count and abnormal electrolyte levels (high sodium, low calcium, and low potassium).

Black Box Warning
Black box warnings are issued by the U.S Food and Drug Administration (FDA) to warn the public about the serious adverse effects of some medications. The most recent black box warning for corticosteroids was issued in 2014. The FDA warned against administering corticosteroid injections into the epidural space of the spine for the treatment of neck/back pain and radiating pain in the extremities [4]. When administered in this way, serious (although rare) adverse effects can occur including vision loss, stroke, paralysis, and death.
Drug Interactions
The therapeutic effect of corticosteroids may be counteracted or enhanced when administered with certain medications. Clinicians should perform an accurate medication reconciliation when prescribing/administering corticosteroids to ensure effective and safe treatment.
The following are medications that interact with corticosteroids categorized by a decreased or increased therapeutic effect [1]. Corticosteroid doses should be adjusted accordingly.
Decreased Therapeutic Effect
Medications that can decrease the level of corticosteroids in the blood when administered together include:
- Barbiturates
- Carbamazepine
- Ephedrine
- Phenytoin
- Rifampin
- Cholestyramine (affects oral corticosteroids in particular)
Increased Therapeutic Effect
Medications that can increase the level of corticosteroids in the blood when administered together include:
- Ketoconazole
- Macrolide antibiotics

Clinical Guidelines on Corticosteroid Use in the Critically Ill
Clinical practice guidelines for corticosteroid therapy were developed to assist clinicians and providers in ensuring optimal prescribing and administration practices. Currently, guidelines are in place for corticosteroid use in critical illness. The most recent 2024 guidelines were reestablished for the treatment of septic shock, acute respiratory distress syndrome, and community-acquired bacterial pneumonia, particularly in adult patients.
In the following sections, these guidelines are compared with prior 2017 recommendations [3]. Clinicians practicing in acute care settings can use the following guidelines when prescribing/administering corticosteroids to patients who are critically ill.
Sepsis and Septic Shock
Previously, the guidelines recommend against administering corticosteroids in adult patients with sepsis without shock. Instead, corticosteroids were recommended in patients with septic shock not responsive to fluid and moderate- to high-dose vasopressor therapy.
Current Recommendation: Administer corticosteroids to adult patients with septic shock. Do not administer high dose/short duration corticosteroids for adult patients with septic shock (no more than 400 mg per day of a hydrocortisone equivalent for no more than three days).
Acute Respiratory Distress Syndrome
Previously, the guidelines recommended corticosteroid use in patients with early moderate to severe acute respiratory distress syndrome (PaO2/FIO2 of less than 200 and within 14 days of onset).
Current Recommendation: Administer to adult hospitalized patients with acute respiratory distress syndrome.
Community-Acquired Bacterial Pneumonia
Previously, the guidelines recommended corticosteroid use for five to seven days at a daily dose of less than 400 mg IV hydrocortisone (or equivalent) in hospitalized patients with community-acquired pneumonia.
Current Recommendation: Administer to adult patients hospitalized with severe bacterial community-acquired pneumonia. There is no recommendation for adult patients hospitalized with less severe bacterial community-acquired pneumonia.
Clinical Guidelines on Corticosteroid Use for COVID-19
While data is limited and still developing, both the World Health Organization (WHO) and the National Institutes of Health (NIH) developed clinical practice guidelines for the use of corticosteroids as a treatment for COVID-19.
Clinicians practicing in acute care settings can use the following guidelines when prescribing/administering corticosteroids to patients with COVID-19.
Global Guidelines for Corticosteroid Use for COVID-19
As mentioned earlier, the WHO recommends corticosteroids for the treatment of severe COVID-19 [6]. The 2020 “Corticosteroids for COVID-19: Living Guidance” recommendations are as follows [13]:
- The WHO recommends systemic corticosteroids rather than no corticosteroids for the treatment of patients with severe and critical COVID-19.
- The WHO suggests not to use corticosteroids in the treatment of patients with non-severe COVID-19.
National Guidelines for Corticosteroid Use for COVID-19
The National Institutes of Health (NIH) developed the 2023 “Therapeutic Management of Hospitalized Adults with COVID-19” guidelines outlining various drug therapy recommendations for patients with COVID-19, including corticosteroids. Recommendations are as follows [9][10]:
- The panel recommends against the use of dexamethasone (or other systemic corticosteroids) for the treatment of COVID-19 in patients who do not require supplemental oxygen.
- The panel recommends against the use of dexamethasone (or other systemic corticosteroids) in nonhospitalized patients in the absence of another indication.
- The panel recommends patients with COVID-19 receiving dexamethasone (or another corticosteroid) for an underlying condition to continue this therapy as directed by their health care provider.

Patient Education
Therapeutic and safe corticosteroid use is dependent on safe prescribing and administration practices, as well as patient compliance. Optimal patient education is vital for successful treatment with corticosteroids.
The following are teaching points to share with patients about corticosteroid use [1][6][7].
- Adverse Effects: Patients should be informed of common adverse effects, particularly elevated blood sugar, mood changes, appetite changes, and weight gain.
- Vaccine Safety: Patients should be encouraged to check with their health provider before receiving vaccines (Corticosteroids should not be given with live vaccines)
- Infection Risk: Patients should be informed of the risk for developing an infection when corticosteroid doses are high or used to suppress the immune system, and to therefore avoid exposure to chickenpox or measles.
- Administration: Patients should be instructed to avoid abruptly stopping corticosteroids to prevent adrenal insufficiency and potentially death. They should also be made aware that stress on the body (for example, when having surgery) may require additional doses of corticosteroids.

Future Implications
Corticosteroid use may be on the rise. As aforementioned, corticosteroids are useful in the treatment of autoimmune disease. In the U.S., researchers anticipate a rise in autoimmune diseases in the future.
In a 2020 study in Arthritis and Rheumatology, researchers noted that the prevalence of antinuclear antibodies (ANA) (markers of autoimmune disease) is increasing in the U.S. [8]. The study analyzed the antibodies of over 14,000 participants (age 12 and older) over the course of three time periods. Results revealed the following:
- From 1988 – 1991, 22 million people had antibodies.
- From 1999 – 2004, 27 million people had antibodies.
- From 2011 – 2012, 41 million people had antibodies.
The study also found that antibody prevalence is highest among males, non-Hispanic whites, adults over age 50, and adolescents. Young people age12 to 19 had the highest antibody prevalence. While it is unclear why this is the case among the youth, the study findings may suggest an increase in the use of corticosteroids in the future. Further, clinicians might anticipate changes in clinical guidelines for safe prescribing/administration practices.

Corticosteroids are helpful in the treatment of many medical conditions and diseases. While the use of these medications is common, there are equally associated risks, many of which can be life-threatening. Safe prescribing/administration practices are imperative. Clinicians can ensure that treatments are safe and effective through the gathering of accurate health histories, careful evaluation of each patient’s situation, weighing of risks and benefits, and provision of effective education to patients.

Anti-Arrhythmics
Introduction
Cardiac arrhythmias continue to present significant clinical challenges and remain a cause common of death and disability [5]. Arrhythmias encompass a wide array of heart rate and rhythm disturbances; they are classified into broad terms as bradyarrhythmia’s (heart rates below 60 beats per minute) and tachyarrhythmias (heart rates exceeding 100 beats per minute) [10].
The defining feature of cardiac arrhythmias is an irregular heartbeat, or a symptom of abnormal heart rhythm linked to irregular initiation of electrical impulses, or a combination of both factors.
The mechanisms underlying cardiac arrhythmias are complex. The management of these conditions often involves the administration of antiarrhythmic drugs. It is vital that prescribers are aware of the pharmacokinetics of this drug class.
Overview of Cardiac Arrhythmias
Arrhythmias impact an estimated 17 million individuals across the planet, they rank among the most prevalent forms of heart disease [8]. The clinical manifestations of arrhythmias vary from asymptomatic individuals to sudden cardiac death (SCD), contributing to 10–15% of all mortality cases [10].
The only pattern considered to be a normal heart rhythm is the normal sinus rhythm. In this state, an electrical impulse originates in the sinoatrial (SA) node and travels through the heart [1]. This delayed impulse occurs in the atrioventricular (AV) node, then it proceeds through the His-Purkinje network, which encompasses the bundle of HIS, the left and right bundle branches, and the Purkinje fibers [1]. These reactions essentially coordinate each beat of the heart.
Despite the notable limitations associated with existing antiarrhythmic medications, pharmacological intervention remains a fundamental aspect of managing cardiac arrhythmias [5]. Research suggests that arrhythmias occur in 1.5% to 5% of the general population, with atrial fibrillation being the most prevalent form [1, 10].
Arrhythmia refers to any deviation from the heart's normal rhythm, with the normal sinus rhythm being the baseline for a healthy heart rhythm [1]. The categorization of arrhythmias occurs through various criteria, with the most prevalent method being the heart rate of conduction. This includes bradyarrhythmia’s, where the heart beats slower than 60 beats per minute (bpm), and tachyarrhythmias, where the heart rate exceeds 100 bpm [1].
Atrial fibrillation (AF) is the most frequent occurring sustained cardiac arrhythmia and linked to heightened morbidity and mortality rates, in addition to increased healthcare costs [2][3].
Arrhythmias may originate from congenital anomalies (present from birth) or can develop due to irritation or damage to the myocardial tissue, causing disruptions or ‘short circuits’ in the heart's electrical system [13].
Basics of Antiarrhythmic Drugs (AADs)
Antiarrhythmic drugs (AADs) continue to be fundamental in the management of cardiac arrhythmias and classified based on the cardiac action potential [4]. The action of these drugs works toward the immediate cessation of atrial and ventricular arrhythmias (acute cardioversion) and for the long-term prevention of arrhythmia recurrence to maintain normal sinus rhythm [5].
A limited number of new AADs have reached the market despite the growing incidence of cardiac arrhythmias [5].
Two key objectives define the rationale for treating arrhythmias: (1) to mitigate significant clinical symptoms, including weakness, syncope, or the onset or worsening of congestive heart failure caused by an arrhythmia, and (2) to extend the patient's lifespan [8].
In the initial stages of antiarrhythmic drug (AAD) development, the primary focus was on controlling ventricular arrhythmias [6]. The direction of treatment changed following the adverse outcomes highlighted by the Cardiac Arrhythmia Suppression Trial (CAST) and the Survival with Oral D-Sotalol (SWORD) trial, which demonstrated that patients receiving AADs (encainide or flecainide) fared worse than those on placebo [6].
The primary criterion of antiarrhythmic drugs is safety. In the last decade antiarrhythmic drugs have been subject to intense reevaluation, prompted by the outcomes of large-scale human research studies that highlighted various risks and limitations associated with pharmacological treatments for arrhythmias [7].
In the Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) study, the trial demonstrated that although achieving rhythm control was associated with improved survival the adverse effects negated survival benefits [8].

Definition
Antiarrhythmic agents, often referred to as cardiac dysrhythmia medications, constitute a category of pharmaceuticals designed to moderate the heart’s electrical impulse and mitigate rapid heart rhythms; these rhythms include atrial fibrillation (AF), supraventricular tachycardia (SVT), and ventricular tachycardia (VT) [11].
This class of drugs influence cardiac ionic channels or receptors, modifying the cardiac action potential, or its creation and transmission [11]. These alterations affect the activation spread or repolarization pattern, suppressing cardiac arrhythmias [12].
Common symptoms of arrhythmias include heart fluttering, abnormal or rapid heart rhythms, lightheadedness, fainting spells, chest pain, and breathlessness. Individuals may also experience heart palpitations, dizziness or feeling faint, chest pain or discomfort, weakness, and fatigue [12].

- How do antiarrhythmic agents contribute to the suppression of arrhythmias and the alleviation of associated symptoms such as heart fluttering, lightheadedness, and chest pain?
- Do you have experience administering antiarrhythmic medications to patients?
Classification of Antiarrhythmic Medications
The categorization of arrhythmias is based on the location within the conduction pathway where they originate.
There are two main groups:
- Supraventricular - originating from the atria or the atrioventricular (AV) node.
- Ventricular - occur distal to the AV node.
[23]
Prior to 2018, the categorization of antiarrhythmic drugs was based on the Vaughan-Williams (VW) classification system, which organized these medications by their principal mechanism of action [4, 14]. The initial Vaughan-Williams classification had limitations. When introduced in the 1970s, the range of antiarrhythmic drugs focused on altering the function of Na+, K+, and Ca2+ channels, as well as targeting intracellular processes governed by adrenergic activity [15].
Today, there is a broader range of advanced antiarrhythmics, many possessing overlapping interactions with drugs in other classes. For example, amiodarone, categorized under Class III (Potassium channels blockers), also exhibits sodium and calcium-channel blocking properties (Class IV).

Class 0: HCN Channel Blockers
Ivabradine
Ivabradine is designed to lower heart rate. It is used in the management of stable angina pectoris and chronic heart failure with heart rate ≥70 bpm across various clinical scenarios, including those with either preserved or compromised left ventricular (LV) function.
Ivabradine is effective by decreasing heart rate while preserving myocardial contractility and coronary vasomotor responsiveness, thereby reducing oxygen consumption, and extending diastolic duration [16] [17].
Self Quiz
Ask yourself...
- How does Ivabradine's mechanism of action contribute to its therapeutic benefits in patients with stable angina pectoris and chronic heart failure?
Class I: Voltage-gated Na+ Channel Blockers
Class IA
Class IA medications block fast sodium channels and include agents such as quinidine, procainamide, and disopyramide [11]. Quinidine, disopyramide, and procainamide are used in the management of supraventricular tachyarrhythmias, recurrent atrial fibrillation, ventricular tachycardia, ventricular fibrillation, Brugada syndrome, and Short QT Syndrome (SQTS) [4].
These drugs are associated with the highest risk of proarrhythmic among sodium channel blockers due to their capacity to prolong the QTc interval, which restricts their use because of their proarrhythmic potential [11].
For patients with Brugada syndrome, Quinidine is an alternative to implantable cardioverter-defibrillator (ICD) placement [66].
This class has also shown utility in individuals with short QT syndrome experiencing recurrent ventricular arrhythmias (VAs), reducing the frequency of ICD shocks in these patients [66].
Disopyramide is employed in cases of hypertrophic obstructive cardiomyopathy (HOCM), when combined with a beta-blocker or verapamil to alleviate symptoms like angina or dyspnea in patients unresponsive to beta-blockers or verapamil alone [67].
Procainamide is useful for exposing and diagnosing Brugada syndrome in individuals suspected of the condition but without a confirmed diagnosis [68]. Procainamide has shown to reestablish sinus rhythm in patients with Wolff-Parkinson-White (WPW) syndrome who experience atrial fibrillation (AF) without hemodynamic instability, which is marked by a wide QRS complex or a rapid pre-excited ventricular response [69]. Procainamide may also assist in terminating ventricular tachycardia and other arrhythmias [69].

Class IB
Lidocaine and Mexiletine treat ventricular tachycardia and ventricular fibrillation after a myocardial infarction by inducing a mild blockade of sodium channels [4]. These are not effective for treating atrial arrhythmias [4].
In the context of long QT syndrome, mexiletine is capable of reducing the QTc interval and has been employed to decrease the incidence of recurrent arrhythmias and the need for interventions by implantable cardioverter-defibrillators (ICDs) [70].
The effectiveness of Lidocaine diminishes in instances of hypokalemia, necessitating the correction of potassium levels [80].

Class IC
Research recommends Encainide (Enkaid), flecainide (Tambocor), and propafenone (Rythmol SR) for managing supraventricular and ventricular tachyarrhythmias that do not respond to standard treatments, in the absence of underlying structural heart disease. [72].
Propafenone increases the effects of cyclosporin, desipramine, and theophylline [81].
Class IC is used to treat premature ventricular contractions and catecholaminergic polymorphic ventricular tachycardia [18]. These drugs block sodium channels without altering the QT interval and suit ongoing management in individuals with symptomatic supraventricular tachycardia (SVT) who have no structural or ischemic heart disease, and either are unsuitable for or opt against catheter ablation. [11].
In addition, these agents are effective for the pharmacological cardioversion of atrial fibrillation (AF). The “pill in the pocket” strategy involves patients with paroxysmal AF carrying a loading dose of medication to take at the onset of an AF episode. This approach aims for chemical cardioversion to restore normal rhythm, rather than adhering to a regular maintenance dose regime [71].
The Cardiac Arrhythmia Suppression Trials (CAST I and II) showed that patients with a history of myocardial infarction, treated with class IC agents (flecainide, encainide, moricizine) to reduce premature ventricular contractions (PVCs), faced a higher mortality risk compared to those receiving placebo [72].

Class ID
Ranolazine presents a potential therapeutic option for managing tachyarrhythmias and ventricular tachycardia [19].
Class II: Autonomic Inhibitors/Activators
The literature recommends beta-blockers (BB) for managing the heart rate in individuals with paroxysmal, persistent, or permanent atrial fibrillation (AF) and atrial flutter [73]. Beta-blockers (BB) are also beneficial for long-term management in patients with symptomatic supraventricular tachycardia (SVT) [73].
Due to their favorable safety profile and efficacy, healthcare professionals can consider beta-blockers as the first-choice therapy for ventricular arrhythmias [39]. Their use is associated with a reduction in adverse cardiac events in conditions such as long QT syndrome and catecholaminergic polymorphic ventricular tachycardia [74].
For patients exhibiting symptomatic premature ventricular contractions (PVCs) in the absence of underlying heart disease, beta-blocker therapy can help decrease the frequency of recurrent arrhythmias and alleviate symptoms [75].

IIa: Inhibitors including pindolol, carvedilol, timolol, nadolol (non-selective beta-blockers), and bisoprolol, atenolol, metoprolol, esmolol (selective beta-1 blockers) treat rate control in atrial fibrillation, atrial flutter, and ventricular tachyarrhythmia [4].
IIb: Activators: The use of Isoproterenol can manage ventricular escape rhythm in cases of complete AV block before pacemaker implantation [4][20].
IIc: Inhibitors: Atropine treats symptomatic sinus bradycardia and conduction block [4][21].
IId: Activators: For the management of supraventricular tachyarrhythmias, Carbachol, methacholine, and digoxin [4].
IIe: Activators: Adenosine for the cessation of paroxysmal supraventricular tachycardia (PSVT) [22].
Class III: K+ Channel Blockers/Openers
Potassium channel blockers decrease potassium efflux out of the cell and prolong the QTc interval [4] Amiodarone displays sympatholytic effects as well as sodium and calcium channel blocking properties, leading to reduced conduction through the AV and sinus nodes [4].
Amiodarone helps maintain sinus rhythm in patients with atrial fibrillation (AF) and those suffering from left ventricular systolic dysfunction [4].
Amiodarone also stands as a viable choice for pharmacological cardioversion and can help manage ventricular rate in critical patients without pre-excitation, though it is less effective than non-dihydropyridine calcium channel blockers [4] [49].
Amiodarone is the preferred antiarrhythmic medication for suppressing ventricular arrhythmias (VA) [4]. Administration of intravenous amiodarone may achieve rhythm stabilization in cases of unstable persistent ventricular arrhythmias (VA) following defibrillation [49]. Administering intravenous amiodarone stabilizes rhythm in cases of unstable persistent ventricular arrhythmias (VA) following defibrillation.
In addition, amiodarone controls ventricular arrhythmias (VA) in patients with ischemic heart disease who are also receiving beta-blocker treatment [4].
Observations show that Dronedarone reduces hospital admissions for atrial fibrillation (AF) in individuals with a history of non-permanent AF who are in sinus rhythm. However, for patients with permanent AF that cannot convert back to normal sinus rhythm, it is contraindicated due to FDA reviews indicating a significant increase in the risk of cardiovascular death, stroke, and heart failure in these cases [76].
Dofetilide is employed in the treatment of atrial arrhythmias and for the acute pharmacological cardioversion of atrial fibrillation or flutter [77].
Sotalol, combining class II beta-blocker properties and class III potassium channel blocker effects, manages both ventricular and supraventricular arrhythmias. [78].
Ibutilide (Corvert) targets the treatment of atrial fibrillation or flutter, underlining its specialized use in managing these specific arrhythmias [79].

IIIA: Voltage-dependent K+ channels
Amiodarone and dronedarone are notable for their role as non-selective potassium (K+) channel blockers, which are crucial in the treatment of unstable ventricular tachycardia and life-threatening recurrent ventricular fibrillation [4].
Kv11.1 (rapid K+ current) blockers: Dofetilide, almokalant, ibutilide, sematilide, and sotalol manage ventricular tachycardia in patients without prior myocardial infarction or underlying structural heart disease. They also treat Wolff-Parkinson-White (WPW) syndrome when associated with atrial fibrillation [4].
Kv1.5 (ultra-rapid K+ current) blockers: Vernakalant serves to convert recent onset atrial fibrillation in patients without structural or ischemic heart disease. It is important to note that the FDA does not approve this specific use of vernakalant [24].
IIIb: Metabolically dependent K+ channels blockers: Nicorandil and pinacidil are employed as second-line treatments for stable angina [25].
Class IV: Ca2+ handling modulators
Non-dihydropyridine calcium channel blockers, such as diltiazem and verapamil, reduce conduction speed and decelerate signal transmission through the AV node [82]. These medications are effective for controlling the ventricular rate in both acute and chronic cases of atrial fibrillation (AF) and atrial flutter [82].
In the acute management of stable patients with supraventricular tachycardia (SVT), including focal and multifocal atrial tachycardias, diltiazem and verapamil serve as viable treatment options [4] [39].

IVa: Bepridil and falipamil, which block non-selective surface membrane calcium (Ca2+) channels, may manage supraventricular tachyarrhythmias [4]. Verapamil and diltiazem, which block surface membrane L-type calcium (Ca2+) channels, treat supraventricular arrhythmias, and control the rate of atrial fibrillation [4].
IVb: Propafenone and flecainide serve as intracellular calcium channel blockers utilized in addressing catecholaminergic polymorphic ventricular tachycardia (CPVT) [4].

Clinical Prescribing Criteria
Antiarrhythmic medications are pivotal in managing symptoms and safeguarding against the decline of cardiac function caused by conditions such as tachycardia, irregular rhythms, or desynchrony [4]. The primary objective is to reestablish normal cardiac rhythm and conduction, averting the onset of more severe and fatal arrhythmias.
Antiarrhythmics have a narrow therapeutic index, indicating a minimal margin between the effective dosage and the onset of toxicity [4]. There is a tenuous balance between suboptimal treatment and the risk of toxic or proarrhythmic effects, underscoring the importance of precise dosing and monitoring. Clinical attention focuses on the patient's clinical status, underlying structural and functional conditions, and the mechanisms of arrhythmia at both cellular and molecular levels.
The use of antiarrhythmic drugs in therapy seeks to alter conduction velocity, by either slowing down or speeding it up, modify the excitability of cardiac cells via changes in the length of the effective refractory period, and suppress unusual spontaneous activity [14].
Numerous variables influence the effectiveness of antiarrhythmic drugs, such as race, sex, genetics, environmental temperature, drug interactions, precipitating factors, changes in neurohormones, the disease's present condition and severity, and disease-driven structural changes in the body [30]. The complexity increases with some antiarrhythmic drugs (AADs) displaying diverse electrophysiological and pharmacological effects that depend on the administration route, plasma concentration, and the existence of active metabolites.
A variety of factors can influence the efficacy of medications, including racial background, gender, genetic makeup, ambient temperature, interactions between different drugs, initiating triggers, neurohormonal fluctuations, the current state and intensity of the disease, and alterations in the body's structure caused by the disease itself [31].
Complicating the pharmacology, certain antiarrhythmic drugs (AADs) exhibit a wide range of electrophysiological and pharmacological actions, which can vary based on the method of administration, concentration levels in the plasma, and the presence of active metabolites [4] [5].

The Cardiac Electrical Cycle (Electrical Cascade)
The cardiac action potential represents the sequence of ion exchanges that result in the successive depolarization and repolarization of the cardiac myocyte, culminating in muscle contraction [4]. During its resting phase, a cardiac myocyte maintains a baseline resting membrane potential ranging from negative 80 to negative 90 millivolts [32].
Antiarrhythmic drugs slow down ion movement during various stages of the cardiac action potential [32].
- Phase 0: The “depolarization” phase of the action potential occurs due to the influx of sodium ions (Na+) into the cell, following an electrochemical gradient, leading to a membrane potential of around positive 30 millivolts [33].
- Phase 1: “The notch,” or the early repolarization phase of the action potential, features potassium (K+) ions flowing out. [4] [33].
- Phase 2: “The plateau” phase occurs when the inward movement of calcium ions (Ca2+) balances the outward movement of potassium (K+) ions [4] [34].
- Phase 3: “The repolarization” phase of the action potential occurs through the efflux of potassium (K+) ions along their electrochemical gradient out of the cell. This movement removes the positive charge of the K+ ion from the cell, reinstating the cardiac myocyte's negative potential [33][34].
- Phase 4: Reactivation of the Na/K-ATPase pump, which re-establishes the resting membrane potential in the cardiac myocyte [4][35].

Pharmacokinetics of Anti-Arrhythmic Medications
Pharmacokinetics involves the study of drug absorption, distribution, metabolism, and excretion. All antiarrhythmic drugs affect the conductance of membranes and ions, modifying cardiac action potential dynamics either via direct or indirect action.
For example, some medications inhibit fast sodium channels, essential for controlling the rate of membrane depolarization (phase 0) during an action potential [33]. Electrical conduction velocity links to membrane depolarization and blocking sodium channels slows this velocity down [32][33]. Slowing conduction velocity is advantageous for eradicating tachyarrhythmias resulting from reentry circuits [36].
Various antiarrhythmic drug classes affect the duration of action potentials and the effective refractory period [37]. Extending the effective refractory period often eradicates reentry tachyarrhythmias [38]. This effect occurs by inhibiting potassium channels and postponing the repolarization phase (phase 3) of action potentials [38].
Medications that inhibit the slow inward calcium channels aim to diminish pacemaker activity by decelerating the depolarizing pacemaker potential’s rate of rise (phase 4 depolarization) [14].
These drugs also decrease the speed of electrical signal transmission through the atrioventricular (AV) node [14][38]. Similar to sinoatrial (SA) node cells, AV nodal cells rely on the influx of calcium ions for depolarization [34]. Due to the potential for sympathetic nervous system activity to cause arrhythmias, beta1-adrenoceptor blockers are employed to diminish the sympathetic impact on the heart [39]. These beta-adrenoceptors connect to ion channels through specific signal transduction pathways, indicating that beta-blockers modify ion conductance across the membrane, influencing calcium and potassium conductance [39].
In instances of AV block, doctors sometimes use drugs like atropine, a muscarinic receptor antagonist, to counteract vagal effects [40]. AV block can emerge as an adverse effect of beta-blocker medication, and stopping the beta-blocker in such cases may return AV conduction to normal [41].
An increased ventricular rate can be a consequence of atrial flutter or fibrillation [42].
In response, medications that slow down conduction through the atrioventricular (AV) node regulate the ventricular rate. Calcium channel blockers and beta-blockers are particularly effective for this purpose [4].
Digoxin proves advantageous for patients with systolic heart failure, also referred to as heart failure with reduced ejection fraction (HFrEF), characterized by an ejection fraction of less than 40% [43]. Nonetheless, it does not contribute to a reduction in mortality [43]. When standard treatments do not achieve heart rate objectives in atrial fibrillation or atrial flutter, clinicians can deploy Digoxin for heart rate management [44].
Administration of digoxin is contraindicated in instances of pre-excitation due to accessory pathways since it promotes AV blockade and could precipitate ventricular tachyarrhythmias [44]. In conditions of elevated sympathetic activity, digoxin is ineffective, and beta-blockers are the preferred treatment option [44].
Healthcare providers favor oral drug formulations for their improved patient compliance, ease of use, and scalability, which offer economic advantages [45]. However, the oral bioavailability of drugs can vary, influenced by differences in physicochemical characteristics and metabolic activities that impact pharmacokinetics [46]. Challenges such as intestinal metabolism, efflux mechanisms in the gastrointestinal tract, and the hepatic first-pass effect hinder the bioavailability of drugs administered orally [46] [47].
The first-pass effect describes a pharmacokinetic process in which a drug undergoes metabolism at a specific site in the body before reaching the systemic circulation or its intended site of action, which reduces the concentration of the active drug available [47]. The liver, a primary location for drug metabolism, has a direct link to the first-pass effect. This effect can also occur in other active metabolic areas of the body, such as the lungs, blood vessels, gastrointestinal tract, and various tissues [47].

Absorption
Antiarrhythmic medications exhibit quick absorption, but the pronounced first-pass effect often reduces their bioavailability [47]. They achieve peak plasma concentrations within 1–3 hours, except for digoxin and dronedarone, which reach their peak in 3–6 hours, and amiodarone, which takes 6–8 hours to peak [11]. In elderly individuals and patients with liver dysfunction, the oral bioavailability of medications tends to be higher [11].
Intestinal bacteria transform digoxin into inactive compounds; antibiotics such as tetracycline and erythromycin eliminate these bacteria, leading to elevated levels of digoxin in the bloodstream [44]. The antiarrhythmic effect of digoxin starts within 2–5 minutes after its intravenous administration [44].
The absorption of drugs through the gastrointestinal tract is crucial for their bioavailability, with meals playing a role that can either enhance or impede this process [46]. For instance, a high-fat meal can increase the oral absorption of dronedarone by fourfold [11].

- How do factors such as age, liver function, intestinal flora, and dietary habits influence the therapeutic levels and efficacy of these drugs in the bloodstream?
Distribution
With the exception of sotalol, antiarrhythmic drugs (AADs) exhibit some degree of binding to plasma proteins [11]. Amiodarone, digoxin, flecainide, and propafenone build up in the heart at concentrations higher than those in plasma and dialysis cannot remove them [11].
The concurrent administration of flecainide and amiodarone increases flecainide plasma concentrations by 50% [48].
Disopyramide, mexiletine, sotalol, and verapamil can cross the placenta and appear in breast milk. High concentrations of Procainamide also occur in breast milk and eliminated by newborns [11].
Oral administration of amiodarone reaches steady-state plasma concentrations after an extended period, except when administered in substantial loading doses; delivering it via intravenous form also delays its maximal effect [49]. This delay is indicative of its distribution across multiple compartments, including the intravascular compartment, which a standard loading dose saturates, a peripheral compartment encompassing various tissues, and a deep compartment represented by adipose tissue, serving as a reservoir for the drug [49].
Amiodarone is known for its distinctive side effects, with a 15% prevalence rate in the first year of use, which can escalate to up to 50% with prolonged treatment [87]. Side effects include pulmonary fibrosis, thyroid dysfunction, photosensitivity, blue-grey skin discoloration, corneal microdeposits, peripheral neuropathy, and elevated liver enzymes [87]. Providers must weigh the potential benefits of amiodarone against its long-term risks [94].

- How does the differential binding of antiarrhythmic drugs to plasma proteins and their accumulation in various body compartments (heart and adipose tissue) affect their pharmacodynamics and pharmacokinetics?
Biotransformation
Antiarrhythmic drugs (AADs) undergo metabolism in the liver through CYP450 isoenzymes, resulting in active metabolites that either block sodium (Na+) channels (such as mexiletine and propafenone), extend action potential duration (APD) [for instance, N-acetylprocainamide (NAPA)], or cause central nervous system (CNS) toxicity (as seen with lidocaine) [11].
Genetics influence the metabolism of CYP2D6 resulting in higher plasma concentrations and extended half-lives (t½) of metoprolol and propafenone in individuals with poor metabolizing capabilities (6% of Caucasians) compared to those who are rapid metabolizers [50]. In similar fashion, the conversion of procainamide to N-acetylprocainamide (NAPA) varies, with 15–20% metabolized in individuals classified as 'slow-acetylators' and 25–33% in 'fast-acetylators' [11].
These metabolic phenotypes are determined by genetics. There are no standard tests available to identify a patient's metabolic phenotype prior to treatment initiation, with the exception of measuring the procainamide/NAPA concentration ratio. It is advisable to decrease dosages for poor or slow metabolizers to two-thirds or less of the standard maintenance dose [11] [51].
Lipophilic beta-blockers, such as bisoprolol, carvedilol, metoprolol, and propranolol, undergo metabolism via CYP2D6, and their bioavailability and half-life (t½) are prolonged in cases of liver dysfunction [11]. The body excretes hydrophilic beta-blockers, including atenolol and sotalol, in their unchanged form through the urine [11].
Following an intravenous loading dose, lidocaine undergoes metabolism with a half-life (t½) of 1.5–2 hours. In patients with liver impairment or decreased hepatic blood flow — including the elderly, those experiencing cardiogenic shock, heart failure, myocardial infarction, or those taking cimetidine and beta-blockers — lidocaine's plasma levels increase, and its half-life extends [51]. In these cases, one should lower both the loading and maintenance doses.
Due to its brief half-life, an initial loading dose of lidocaine requires supplementation with a continuous infusion or repeated administrations to achieve and maintain a consistent plasma concentration [53].
Intravenous Esmolol undergoes rapid hydrolysis in red blood cells, with a half-life of ∼ 9 minutes, and achieves complete reversal of beta-blockade 20–30 minutes after drug cessation [11]. Intravenous adenosine acts within 15–30 seconds, with erythrocytes and vascular endothelial cells absorbing and metabolizing it through adenosine deaminase (ADA), leading to a short half-life (t½) of less than 10 seconds [11].

- How do genetic variations in CYP450 isoenzymes (CYP2D6) affect the metabolism, efficacy, and safety of antiarrhythmic drugs?
Elimination
Antiarrhythmic drugs (AADs) vary in their extent of excretion through urine and feces [11]. The half-life (t½) of these drugs extends in elderly individuals and patients with renal impairment (such as digoxin, disopyramide, dofetilide, flecainide, procainamide, and sotalol) or liver dysfunction (including amiodarone, diltiazem, flecainide, lidocaine, metoprolol, mexiletine, propafenone, propranolol, quinidine, and verapamil) [11]. This prolongation also occurs in congestive heart failure (seen with amiodarone, flecainide, lidocaine, mexiletine, procainamide, and quinidine) or after a myocardial infarction (noted with disopyramide, lidocaine, and mexiletine) [11][54].
For these patients, it is advisable to lower the dosages and to conduct regular ECG monitoring. Amiodarone is subject to extensive metabolism in the liver, excreted through the bile, and has a prolonged half-life (t½) ranging from 25 to 110 days. This extended half-life accounts for the persistence of its effects for weeks or even months following cessation of the drug [11][55].
Due to their short half-life (t½), manufacturers dispense certain antiarrhythmic drugs, including beta-blockers, diltiazem, propafenone, and verapamil, in modified-release formulations [11].
Amiodarone, cimetidine, diltiazem, ketoconazole, procainamide, propranolol, and verapamil elevate plasma concentrations of quinidine [11]. Quinidine acts as a strong inhibitor of CYP2D6 and P-glycoprotein (P-gp), raising the plasma levels of drugs metabolized by this enzyme; it also reduces digoxin clearance, necessitating a 50% reduction in digoxin dosage [11]. Beta-blockers, cimetidine, and halothane cause an increase in plasma concentrations of lidocaine, thereby requiring a reduction in lidocaine dosage [11]. In addition, mexiletine elevates the plasma levels of theophylline, while amiodarone increases the levels of mexiletine [56].
Flecainide and propafenone lead to higher plasma concentrations of digoxin and propranolol. Propafenone (Rythmol) raises the plasma levels of digoxin, metoprolol, propranolol, and warfarin [48]. Mexiletine and quinidine amplify the effects of warfarin; thus, it is advisable to decrease the dosage of warfarin and monitor the prothrombin time/international normalized ratio (INR) [11] [48].
Amiodarone inhibits P-glycoprotein (P-gp) and several cytochrome P450 isoenzymes, such as CYP1A2, CYP2C9, CYP2D6, and CYP3A4, thus increasing the plasma concentrations of drugs metabolized by these pathways or that are substrates of P-gp [94]. Dosage modifications are necessary for medications such as digoxin, flecainide, and warfarin; it is also important to monitor digoxin concentrations and the international normalized ratio (INR) [57][58].
Cholestyramine may decrease the absorption of amiodarone [59]. Since diltiazem and verapamil inhibit both CYP3A4 and P-glycoprotein (P-gp), adjusting the dosages of drugs metabolized by CYP3A4 or are substrates of P-gp becomes necessary [59]. Furthermore, verapamil has the capacity to suppress the liver's metabolism of lipophilic beta-blockers, resulting in elevated plasma concentrations of these medications [60].
There is a significant pharmacokinetic interaction between certain antiarrhythmic/rate controlling medications (such as amiodarone, quinidine, dronedarone, verapamil, digoxin, and diltiazem) and non-vitamin K antagonist oral anticoagulants (NOACs) due to competition for P-glycoprotein (P-gp) or inhibition of CYP3A4 (notably by diltiazem, dronedarone, and verapamil) [61] [62].
Due to these interactions leading to elevated plasma levels of NOACs, experts advise against combining dronedarone with dabigatran and recommend reducing the dose of edoxaban by 50% [62] [63]. Consider reducing the dose of all non-vitamin K antagonist oral anticoagulants (NOACs) when administering amiodarone alongside other P-gp competing substances [64].
Prescribers recommend reducing the dose of dabigatran (Pradaxa) when used with verapamil. Combining edoxaban with verapamil, especially when other P-gp competitors are present, may also necessitate a dose reduction [65].

Other Antiarrhythmic Drugs
- Adenosine is effective for both diagnosing and halting supraventricular tachycardia (SVT) arising from atrioventricular nodal reentrant tachycardia (AVNRT) or orthodromic atrioventricular reentrant tachycardia (AVRT) [83]. Adenosine serves as a diagnostic aid by revealing underlying atrial flutter or atrial tachycardia (AT) [83]. Adenosine can also terminate focal AT caused by a triggered mechanism and distinguish focal AT from AVNRT and AVRT [83]. Adenosine, a purine nucleoside, results from the breakdown of adenosine triphosphate [86]. Within cardiomyocytes, it interacts with Gi-protein type 1 receptors, facilitating swift potassium efflux and hyperpolarization, while also inhibiting calcium influx [86]. These actions decrease the heart rate and slow down conduction velocity by targeting the AV node.
- Digoxin is not a first-line therapy for ventricular rate control in patients with AF, a combination of digoxin and beta-blocker/or non-dihydropyridine calcium channel blockers is a reasonable rate control option in patients with AF and heart failure [84].
Treatment of Overdose
In instances of antiarrhythmic drug overdose, medical professionals must ensure the patient has a clear airway, adequate breathing, and support for circulation [4] [87]. Managing cardiac arrest and severe toxicity from poisoning involves the use of specialized interventions, including antidotes and venoarterial extracorporeal membrane oxygenation (VA-ECMO), alongside fundamental and advanced life support techniques [87].
Symptoms such as nausea, vomiting, neurological manifestations, and lethal arrhythmias characterize Digoxin toxicity [88]. To treat ventricular tachyarrhythmias from digoxin toxicity, clinicians can use lidocaine, and atropine serves as an option for bradyarrhythmia’s. In addition, digoxin-specific antibody fragments prove effective in severe toxicity cases [89].
Therapeutic and excessive dosages of dofetilide may induce Torsades de Pointes (TdP), which clinicians manage by reducing or stopping the drug's dosage [90]. If the arrhythmia persists, initial treatment involves activated charcoal if ingestion occurred within the last 15 minutes, followed by intravenous magnesium and correction of any electrolyte imbalances [90].
For persistent arrhythmias, administering isoproterenol/dopamine may serve as a temporary measure until initiating pacing [90].
In cases of beta-blocker poisoning, treatments involve administering catecholamines, applying high-dose insulin euglycemic therapy, and using vasopressors, noting glucagon for its positive effects on hemodynamics [91].
Treating calcium channel blocker (CCB) overdoses involves administering intravenous calcium, dopamine, and norepinephrine. High-dose insulin therapy can reduce mortality in cases of calcium channel blocker poisoning [60]. For severe shock or cardiac arrest resulting from these overdoses, extracorporeal life support is employed [60]. Case reports indicate that clinicians use lipid emulsion therapy to treat overdoses of amiodarone and flecainide [4] [92].

Conclusion
Arrhythmias encompass a broad spectrum of heart rate and rhythm disturbances and present significant clinical challenges. Atrial fibrillation (AF) is the most prevalent arrhythmia, associated with increased morbidity, mortality, and healthcare costs [2][3]. Management involves antiarrhythmic drugs (AADs), which play a fundamental role despite their limitations and the potential for adverse effects.
Antiarrhythmic agents, classified by their primary action mechanism on the cardiac action potential, impact ionic channels or receptors, aiming to suppress arrhythmias [4]. The management objectives for arrhythmias include alleviating significant clinical symptoms and extending life.
Pharmacokinetic aspects, such as drug absorption, distribution, metabolism, and excretion, play crucial roles in the effectiveness and safety of AADs. Pharmacodynamics involves modifying the cardiac action potential and conduction velocity to prevent or terminate arrhythmias. Factors influencing drug efficacy include genetics, environmental conditions, and the patient's specific clinical profile.
Treatment of overdose with antiarrhythmic drugs requires immediate medical intervention, including antidotes and supportive measures like venoarterial extracorporeal membrane oxygenation (VA-ECMO) for severe cases. The management of specific drug toxicities, such as digoxin and beta-blockers, involves targeted therapies and supportive care to mitigate adverse effects and stabilize the patient's condition.

Nursing Care in Lewy Body Dementia
Introduction
Lewy body dementia is one of the more common causes of dementia. Currently it is the second most common dementia disorder following Alzheimer’s disease [2]. This condition is shown to affect more than 1.4 million people in the United States [1] [2]. Of dementia cases in older adults, Lewy body dementia is said to make up 5% of people with dementia [2]. Lewy body dementia is a disorder that progresses over time [1]. The progression of the disease differs between individuals and the severity of the symptoms [1].
On average an individual lives between five to eight years after diagnosis [1]. Currently there is not a cure for this disease [1]. This course will examine the causes of this disease, signs and symptoms patients might experience, diagnostic tests, types of management, and educational resources for family members. This course is designed to inform nurses about this common disease and to use this information in their daily practice to care for their patients.
Self Quiz
Ask yourself...
- What do you think is the most common form of dementia in the United States?
- How common is Lewy body dementia in other parts of the world?
- Is there currently a cure for Lewy body dementia?
- Why do you think Alzheimer’s disease is more common than Lewy body dementia?
Definition
Lewy body is an umbrella term that includes two separate diagnoses: Dementia with Lewy bodies and Parkinson’s disease dementia [5]. As these diseases progress, they develop together and are seen as one entity, not two separate conditions [4]. Lewy body dementia is a condition that involves neurocognitive disorders that include hallucinations, memory loss, behavior changes, and parkinsonism features [2]. This disease can also affect intellectual abilities and cause individuals to act out dreams during REM (rapid eye movement) sleep [2]. REM sleep behavior disorder sometimes may be experienced before any other symptoms are exhibited [2].
Lewy body dementia is known for a buildup of deposits of alpha- synuclein proteins called Lewy bodies [1]. Diagnosing this condition can be difficult because many neurological disorders have similar symptoms. Lewy body dementia and Parkinson disease dementia are very similar. For a diagnosis of Lewy body dementia, there must be a cognitive impairment with motor symptoms occuring in less than 12 months [3]. Parkinson’s disease dementia affects an individual’s movements; cognitive symptoms appear later (greater than one year) [5].
Lewy body dementia is known to affect older adults generally between the ages of 50 and 85 [2]. This disease is said to be underdiagnosed due to a large number of diagnoses occuring post-death during autopsies [4]. Several medications used to treat neurocognitive and behavioral symptoms in other conditions can worsen the symptoms of Lewy body dementia [4]. Therefore, an accurate diagnosis can impact an individual’s quality of life.

Epidemiology
Lewy body dementia affects a significant number of individuals in the United States. This condition is found more often in men than women [4]. Age is thought to be the greatest risk factor for an individual developing this disease [4]. An individual who has a family history of Lewy body dementia and Parkinson’s disease is at a higher risk for developing this condition [3].
Lewy Body dementia is more widespread in European, Asian, and African ethnic groups [3]. In individuals with Parkinson’s disease, the incidence of Parkinson’s disease dementia is said to be around 25-30% [4]. The incidence of individuals with Parkinson disease developing this type of dementia after having Parkinson’s for more than 20 years increases to around 83% [4].

Pathophysiology
There is a buildup of alpha- synuclein proteins that causes neurons to die in Lewy body dementia [2] [5]. As mentioned above in this course, this buildup of proteins is called Lewy bodies. The death of neurons that produce dopamine result in problems with movement, cognitive impairment, a decline in cognition, and sleep disturbances [4]. In Lewy body dementia there is a deficiency of acetylcholine [3]. There is also a decrease in acetylcholine with Alzheimer’s disease, but the deficiency is greater with Lewy body dementia [3]. The decrease in neurons that produce acetylcholine causes memory loss and learning impairment [4].
The mutation of synuclein alpha and synuclein beta genes can cause dementia with Lewy bodies [2]. Mutations in apolipoprotein E and GBA genes are potential risk factors for developing the disease [2]. There have been cases where a buildup of alpha-synuclein was found during an autopsy, but the individual did not show any clinical signs of Lewy Body dementia when alive [4]. The function of these proteins in this condition is still undetermined [5].

Etiology
The exact cause of Lewy body dementia is still unknown. While research is ongoing and new developments are occuring, the specific cause has not been determined. The accumulation of Lewy bodies cause cell death which causes symptoms, however, the reason for the buildup of Lewy bodies is still under research [5]. As mentioned earlier, there are specific gene mutations that have been shown to increase the likelihood of producing altered alpha- synuclein proteins, in turn causing them to clump together (forming the Lewy bodies) [2].
The mutation of the GBA gene interferes with the function of lysosomes, which can affect the breakdown of the alpha- synuclein proteins, causing the proteins to accumulate [2]. The e4 allele type of the APOE gene has been shown to increase the risk of developing Lewy body dementia [2]. These clumps of Lewy bodies form inside and outside of neurons in different areas of the brain, where they can alter the function of the cell and can cause the cell to die [2].
The neurons that develop the neurotransmitter dopamine are especially impacted by these clumps of Lewy bodies, which was addressed earlier in this course [2]. Further research is required to find out why these Lewy bodies develop in certain individuals. Currently, age, genetics, and environmental factors are some of the greatest risk factors [3].

Clinical Signs and Symptoms
Lewy body dementia is a progressive disorder – the signs and symptoms worsen over time. The symptoms that are more common are sleep changes, impaired behavior, movement, and cognition [5]. Research shows that the location of Lewy body accumulation impacts the clinical signs and symptoms the individual experiences [3]. If Lewy bodies develop in the brainstem and cerebral cortex first, the condition is called dementia with Lewy bodies, and the onset of the dementia is early [3]. If Lewy bodies accumulate in the brain stem and then develop into the cerebral cortex as time passes, the onset of dementia appears later, and this condition is called Parkinson’s disease dementia [3].
Rapid Eye Movement Sleep Behavior Disorder
Rapid eye movement (REM) sleep behavior disorder is sometimes the first clinical sign of dementia with Lewy bodies [2]. Individuals with this disorder move and talk while dreaming in their sleep [2]. The movements can be violent and cause the individual to fall out of bed [5]. Individuals may kick, punch, and scream in REM sleep (the second half of their sleep) [4]. REM sleep behavior disorder is seen in 76% of patients with dementia with Lewy bodies [4].
This disorder can cause fractures and contusions in some individuals resulting from falling out of bed [4]. This can not only affect the individual, but also the sleep partner of the patient [4]. In some cases, separate sleeping arrangements are needed for the safety of the individual and their sleeping partner. A questionnaire by the patient and sleep partner is part of the diagnosis of REM sleep behavior disorder [14]. If the individual does sleep next to someone, this questionnaire can be helpful as most of the time the patient cannot recall the events while asleep [14]. Video polysomnography is required for a complete diagnosis of this disorder [14]. These events while asleep must be repeated to meet the diagnostic criteria [14].
Other Sleep Disorders
Other disorders of sleep include sleepiness in the daytime, restless leg syndrome, confusion when awakened, and obstructive sleep apnea [4].
Visual Hallucinations
Visual hallucinations are present in about 80% of individuals with Lewy body dementia [1]. Visual hallucinations are a core clinical symptom of dementia with Lewy bodies [4]. They are more common in women than in men [4]. Individuals are aware of these hallucinations and can tell others what they experienced [4]. Visual hallucinations are vivid to individuals and have been said to range from people walking around the house to seeing people that have died sitting next to them [6]. During the beginning stages of the disease, the hallucinations do not seem to affect the patient as much as when the disease progresses [6]. Patients are said to be afraid of these hallucinations in the later stages of the disease [6]. Nonvisual hallucinations are less common, however can occur in some patients [1]. These hallucinations include smelling or hearing something that is not in their surroundings [1].
Fluctuation in Cognition
Fluctuation in cognition is also a clinical sign that is associated with dementia with Lewy bodies [4]. This symptom includes changes in attention, concentration, and alertness [5]. These changes are random and can differ day-to-day [1]. Symptoms can include delirium, and mimic symptoms that are caused by metabolic diseases, which can further the difficulty with identifying the correct diagnosis [4]. To diagnose dementia with Lewy bodies, one of the episodes must be confirmed [4]. These fluctuations can be present in other forms of dementia in their later stages but when present in earlier stages, they point to dementia with Lewy bodies [4].
Memory loss that impacts activities of daily living can be found in later stages of Lewy body dementia [1]. Memory loss early on is more often a characteristic sign of Alzheimer’s dementia [1]. Confusion about the individual’s whereabouts, and inability to multitask can also occur in dementia with Lewy bodies [4].
Problems with Movement
Problems with movement are signs of Lewy body dementia. Bradykinesia (slow movements) and rigidity occur in about 85% of individuals with dementia with Lewy bodies [4]. Tremor at rest is less common in individuals with this condition [4]. Loss of coordination and difficultly swallowing can occur [1]. Problems with movement greatly increase the risk of falls for these individuals [4]. This can place strain on the individual’s caregivers [4].
Autonomic Dysfunction
Autonomic dysfunction can be present in dementia with Lewy bodies and Parkinson’s disease dementia. This symptom is seen in about 90% of patients with Lewy body dementia [4]. The symptoms that result from autonomic dysfunction can be constipation, urinary incontinence, orthostatic hypotension, erectile dysfunction, and dizziness [1] [4]. Orthostatic hypotension appears as early as five years prior to the diagnosis of Lewy body dementia [4]. Syncope and falls are usually the result of orthostatic hypotension [4]. Constipation can also occur earlier in the disease process [4].

Diagnostic Tests and Evaluations
Throughout this course, it has been mentioned that Lewy body dementia is significantly underdiagnosed. Individuals are usually diagnosed as the disease progresses due to the symptoms that overlap with other forms of dementia and other neurological and psychiatric disorders [3]. An autopsy of the brain after death is one of the only ways to have a conclusive diagnosis of Lewy body dementia [16]. There are certain diagnostic criteria and diagnostic tests that are used to diagnose an individual with Lewy body dementia.
Diagnosis by Symptoms
Lewy body dementia is probable when an individual experiences dementia and two main features of the disease. Lewy body dementia is a potential diagnosis if the individual experiences progressive dementia and one main feature of the disease [3]. As discussed in the clinical signs and symptoms section of this course, key features of Lewy body dementia are cognitive fluctuations, dementia that progresses, problems with movement (signs of parkinsonism), REM sleep behavior disorder, and visual hallucinations [3] [16].
Timing of symptoms is relevant for distinguishing between the two forms of Lewy body dementia [3]. Currently healthcare providers use the time span of one year to distinguish the two forms [3]. If dementia occurs within one year of the appearance of movement problems, then a diagnosis of dementia with Lewy bodies is used [3]. If an individual is diagnosed with Parkinson’s disease and starts experiencing symptoms of dementia more than one year after their Parkinson’s diagnosis, then Parkinson’s disease dementia is used [3]. Some indicative biomarkers in addition to clinical symptoms are used in diagnosis [4]. Some of these biomarkers can be found in cerebral spinal fluid (CSF) and are still under research [4].
Cognitive Tests
Cognitive testing can be used to show the cognitive impairment of patients with Lewy body dementia [3]. The Mini-Mental State Examination can be used as an initial screening test [4]. This exam tests cognitive function by focusing on concentration, orientation, and memory [15]. This test can be limited since symptoms of these patients can fluctuate day to day [3]. Another cognitive function test is the Montreal Cognitive Assessment (MoCA) [15]. Providers do not usually diagnose based on a single test; instead, they use the results to look for other signs and symptoms of Lewy body dementia [4].
Imaging Tests
There are certain imaging tests that can help with diagnosis and distinguishing between other dementia disorders. A single-photon emission computerized tomography (SPECT) scan can help support a diagnosis [16]. This is a nuclear scan that can sense radioactivity [16]. If the SPECT scan shows a reduced dopamine transporter uptake in the basal ganglia, this can be a sign of Lewy body dementia [16]. This will separate the diagnosis between Lewy body dementia and Alzheimer’s disease [4]. Performing this scan alone will not lead to a possible diagnosis of Lewy body dementia; however, in combination with other diagnostic tests, the scan can lead to a more certain diagnosis [4]. Results from these scans can appear normal initially, and the scan may need to be repeated [4].
An iodine- MIBG myocardial scintigraphy can be performed to support Lewy body dementia [16]. This would show decreased communication of cardiac nerves [16]. The results may be skewed by heart disease or certain drugs [4]. A CT or MRI may be used but these imaging tests can present mixed results [4]. With Alzheimer’s disease, significant atrophy is seen in the medial temporal lobes [4]. There is normally minimal atrophy in Lewy body dementia [4].
As mentioned earlier in the course, video polysomnography is needed for the diagnosis of REM sleep behavior disorder [14]. This sleep study without the loss of muscle tone can also point towards a diagnosis of Lewy body dementia as REM sleep behavior disorder has now moved to a key feature of this disease [14].

Case Studies
Case Study #1
A 74-year-old male presents to his primary care provider after his wife reports abnormal behavior over the past several months. His wife reports the patient kicks and screams during sleep. The patient reports seeing little people walking around the living room during the day. The wife states the patient some days will fall asleep throughout the day while completing activities. The patient states difficulty walking and muscle stiffness.
The wife states last week the patient was supposed to go to the local grocery store to buy milk. After two hours passed, the wife called her husband as she was worried about him. He states he got lost finding the grocery store and did not know where he was. The wife said she had to drive to find her husband and bring him home. The patient also reports dizziness when standing. After the nurse obtained an orthostatic blood pressure, the patient was positive for orthostatic hypotension.

Case Study #2
A 70-year-old female presents to the emergency department via EMS after falling at home. The patient’s daughter called 911 after finding her on the floor when going to visit her. Upon arrival at the emergency department the patient is oriented to self. The patient does not know where she is or what happened to precipitate the fall. The patient has a past medical history of hypertension, diabetes type II, and Parkinson’s disease.
The patient was diagnosed with Parkinson’s disease two years prior. The daughter states the patient has been forgetful lately and not acting like herself. The daughter reports that her mom’s behavior is different from day-to-day. An MRI and the National Institutes of Health Stroke Scale (NIHSS) are used to rule out a cerebrovascular accident. A complete blood count (CBC), a complete metabolic count (CMP), and urinalysis are obtained. The patient suffered a contusion to her right cheek and a right radius fracture. The patient states that she sees figures dancing in the room and smells popcorn. The patient appears to be frightened by the hallucinations. The patient’s daughter states for the last six months the patient has had difficulty swallowing and a reduced appetite.

Management
Currently there is not a cure for Lewy body dementia, only supportive treatment. The management of this disease involves a multifaceted approach, including therapies, pharmacological treatments, and family support.
Therapies
Specific therapies can help with symptom management and help improve the individual’s quality of life. Occupational therapy can help improve a patient’s ability to complete activities of daily living. Speech therapy can help with swallowing coordination and improve the clarity and volume of speech [5]. Physical therapy can aid patients with problems with movement [5]. Mental health counseling can help individuals and their families with managing behaviors and their emotions [5].
Medications
Pharmacotherapy can help with supportive treatment but can also worsen symptoms if certain medications are taken. Below are some examples of medications that are used by patients with Lewy body dementia.
- Cholinesterase Inhibitors are used to help cholinergic activity to improve cognitive function [6].
- Rivastigmine was one of the first of these drugs to be tested [6]. Patients were noted to have improved on their cognitive exams [6]. It is also shown to reduce hallucinations and lessen anxiety [6]. This class of drugs has been said to improve the quality of life for some patients [4].
- Donepezil and Galantamine are also used to reduce dementia symptoms of hallucinations [6]. These drugs were initially targeted for patients with Alzheimer dementia, however, they are effective for individuals with Lewy body dementia as well [3]. A study was done stating even if there is not a sign of cognitive improvement, this should not be the criteria to stop the medication as this medication has been proven to protect the individual from further impairment of cognition [4].
- Atypical Antipsychotics are prescribed to patients that are not seeing a reduction of symptoms while on cholinesterase inhibitors [3]. These types of drugs are seen as controversial due to the many adverse effects that have been seen in patients [4]. Drugs such as haloperidol and olanzapine should be avoided in patients with Lewy body dementia as they can cause neuroleptic malignant syndrome (a life-threatening condition) [5]. Quetiapine, clozapine, pimavanserin, and aripiprazole are atypical antipsychotic drugs that can be used to improve agitation and help prevent cognitive fluctuations [5].
- Carbidopa-Levodopa can be used in patients to manage problems with movement [3]. This medication can cause side effects and can result in hallucinations, delusions, and increase confusion [3]. Providers should begin with low doses of this medication [3].
- Clonazepam is a benzodiazepine that can lessen the REM sleep behavior disorder that patients with dementia with Lewy bodies can experience [5]. Between 33-65% of patients with REM sleep behavior disorder can experience an injury while sleeping [5]. This medication has been proven to decrease injuries that occur during sleep [5]. Clonazepam can adversely affect individuals with gait disorders or sleep apnea [5].
- Melatonin is a hormone that can be used for patients that are affected by REM sleep behavior disorder (5). Studies have shown that the use of melatonin lessened the frequency and the severity of symptoms associated with REM sleep behavior disorder [5]. Melatonin can have side effects such as headaches in the morning, sleepiness during the day, and hallucinations [5].
- Memantine is used to treat dementia symptoms [5]. This medication is an NMDA receptor antagonist that stops effects of glutamate in the brain [5]. Memantine has been shown to improve symptoms of patients early in the disease [5].

Nursing Care
As mentioned before, there is not a cure for Lewy body dementia. Caring for patients with Lewy body dementia includes supportive treatment. Nurses can play a significant role in caring for these patients and providing the family with support. Home health nurses can help with frequent assessment of the patient and their environment [3]. Environmental changes may be needed to protect the patient from falls and other accidents. Home health nurses can assess the type of assistance the patient would benefit from.
Nurses can aid the family by providing education to assist in how to care for the patient. Family members and caregivers must be aware of the changes in behavior, fluctuations in cognition, and hallucinations that the individual might experience [3]. Nurses must also provide education to the caregiver of the patient on the side effects of certain medications, as they can affect an individual with this disease [7].

Family Support
Lewy body dementia is growing in recognition; however, many people might not be aware of this condition and the disease process. Family members need support from health care professionals to better care for their loved ones. Support can come in the form of education and preparing the family for the symptoms the individual may experience. The cognitive function of patients with this disease can be very limited [3]. Family members must be educated on monitoring the individual closely to promote safety [3]. These individuals are at a high risk for falling and developing aspiration pneumonia (due to swallowing difficulties) [3]. Family members should be educated in preparing for an emergency.
Individuals with Lewy body dementia may need care and the family needs to know how to inform health care providers of their specific needs. It is important to educate family members that their roles in their past relationship with the patient will likely change due to the disease process. To prevent caregiver burnout, family members must be aware of their limitations and know when they need help [7]. Modifying the patient’s home may be needed for patient safety [3]. Each patient may have specific needs and family members should know what modifications may be necessary [3].

- Can nurses help to prevent caregiver burnout?
Prognosis
The prognosis of Lewy body dementia can be viewed as poor. As mentioned briefly earlier in this course, this disease is progressive and after diagnosis, the life expectancy is five to eight years [3]. The range of expectancy has also been attributed to delay in diagnosis, which can further delay supportive treatment to improve quality of life for the individual [3]. Patients can die from complications from the disease. Complications can include cardiac complications, falls, adverse effects from medications, pneumonia, and suicide [3].
Compared to Alzheimer’s dementia, the risk of hospitalization or death due to respiratory infections is higher in patients with Lewy body dementia [8]. The median age at death is said to be similar between patients with Alzheimer’s dementia and Lewy body dementia [8]. The life expectancy from diagnosis to death is shorter in patients with Lewy body dementia [8]. The patient’s environment has been shown to play a role in the increased risk of mortality [8]. Patients in nursing homes have been shown to have a higher risk of mortality [8]. Caregivers can decrease the risk of complications by educating themselves on this disease and keeping their loved ones safe.

Resources for Family Support
Lewy body dementia is a diagnosis that can affect all aspects of an individual’s life and their family members lives. As nurses we must provide support for family members so they can better care for their loved ones and improve their quality of life. As recognition of this condition grows, family support resources are increasing. The Lewy Body Dementia Association is a nonprofit organization that raises awareness and provides support for families with individuals that suffer from Lewy body dementia [10]. Support groups can be found on their website to help families across the country in their local area [10].
The Lewy Body Dementia Association was started by caregivers of individuals with this condition. They also focus on education and research into the disease. This association is a resource for family members [10].
Another resource for family members is The Lewy Body Dementia Resource Center. This is a nonprofit charitable organization that gives assistance and support to those who care for someone with Lewy body dementia [9]. This organization was founded by caregivers of individuals with Lewy body dementia. They have a support phone line that is available seven days a week to answer questions [9]. They also promote research and early diagnosis of this disease [9].

Research Programs
Lewy body dementia is the second most common form of dementia in the United States [4]. This illness is thought to be underdiagnosed and commonly mistaken for other neurological disorders [3]. Research on Lewy body dementia can decrease the time it takes to diagnose a patient, and can help with management of the condition.
The National Institute of Neurological Disorders and Stroke provides support for a variety of research endeavors for Lewy body dementia [11]. In 2021 The National Institute of Health spent $93 million dollars on Lewy Body dementia research [11]. One program is the Biomarkers for Lew body dementias program. This program aims to increase clinical data collection from patients with this condition, find biomarkers to expand further research, and allow access to the science community to help with further studies [11]. Another program is the Parkinson’s Disease Biomarkers Program. This program’s purpose is to collectively research with healthcare professionals, patients and family members, and technology professionals to increase biomarker research [11].
Biomarker research has been increasing in Lewy body dementia. A biomarker is a feature that can specifically indicate a certain disease [12]. For quite some time there were not any identified biomarkers for Lewy body dementia. There are certain biomarkers that aid in distinguishing Alzheimer’s disease from Lewy Body dementia [13]. These biomarkers can be assessed through imaging or in cerebral spinal fluid [13]. Currently these biomarkers are only helpful if another disease is doubtful [13].
New biomarkers are needed to separate Alzheimer’s dementia from Lewy Body dementia and other neurological disorders [13]. Biomarkers that can help with early diagnosis would be beneficial for early treatment [13].

Conclusion
Lewy Body dementia affects 1.4 million Americans [2]. The disease is underdiagnosed and often diagnosed incorrectly. Incorrect diagnoses can lead to worsening of symptoms and the administration of drugs that can lead to adverse effects.
Educating healthcare providers and the community about Lewy body dementia can improve quality of life for individuals with the disease. As nurses, we must be informed about this disease to better educate our patients and their caregivers, and to know how to advocate for our patients.
