What is Compassion Fatigue?
Carla Joinson coined the term “compassion fatigue” in 1992, referring to it as the “cost of caring” and the “loss of the ability to nurture.”
Since then, varying definitions for compassion fatigue have come into play. Simply stated, compassion fatigue “describes the physical, emotional, and psychological impact of helping others — often through experiences of stress or trauma.” Some may refer to it as secondary stress reaction, secondhand shock, secondary traumatic stress, or vicarious trauma. This is mostly because it’s associated with occupations that may have stressful environments.
This is not to be confused with the term “burnout,” which is more a byproduct of what you might experience due to compassion fatigue. This will be discussed later when I get into the impact compassion fatigue has on nurse well-being and patient care.
What Causes Compassion Fatigue in ED Nurses?
Patient Acuity and Volume
Aside from the urgent care cases (common colds, etc.), patient acuity in the ED is generally high. Caring for the critically ill and critical injuries can be emotionally and mentally taxing. Unlike other areas where you may care for the same patients for the full 12-hour shift, the ED has high patient turnover. There’s a constant flow of patients, which does not allow for adequate breaks during most shifts.
Patient Population and Exposure to Trauma
ED nurses work with patients who have alcohol or substance-use disorders, psychiatric patients, life-threatening injuries, and more. Many ED nurses have a mindset that they know what they signed up for. Dealing with stressful encounters is a part of the job. It is common to think you’ve built up a tolerance. But there are only so many times you can witness traumatic events before they start to affect you.
Exposed to traumatic events on a regular basis can result in secondary traumatic stress. Where a nurse may think a tolerance has been built up, the reality is the constant stress can affect resilience over time.
Work Environment
A supportive work environment allows nurses to provide adequate patient care. Challenges such as understaffing, limited resources, and feelings of insufficient support from leadership, can intensify compassion fatigue. As stated before with patient volume, the inability to take breaks during a longer shift can also contribute to physical and emotional exhaustion.
Neurological Effects of Compassion Fatigue
The neurological effects associated with compassion fatigue are multi-dimensional. Below I will discuss the areas where compassion fatigue can lead to adverse neurological effects:
Chronic Stress Response
Compassion fatigue can activate the hypothalamic-pituitary adrenal (HPA) axis. The HPA is the communication system between the hypothalamus, pituitary gland, and adrenal glands. Its function is to regulate the body’s stress reaction by releasing stress hormones, such as cortisol.
Chronic activation of this stress response can result in persistent high cortisol levels, which can cause immune system dysfunction, cardiovascular issues, and metabolic issues. Chronic stress response also causes neurological issues, disrupting neurotransmitters, such as serotonin and dopamine, which are instrumental in mood regulation and cognitive function.
Cognitive Impairment
High levels of stress hormones can cause structural changes in the brain, leading to memory issues. This is due to the impairment of the hippocampus. In addition to memory impairment, chronic stress can affect the prefrontal cortex. This subsequently affects judgment, decision-making and problem-solving abilities. It affects how the brain decides whether to persist or quit.
Emotional Dysregulation
Compassion fatigue can also lead to increased amygdala activity. Known as the brain’s “fear center,” the increased activity can result in symptoms of anxiety and depression, or even emotional numbness. You might develop an emotional detachment — a precursor to apathy in patient care.
Physical Manifestations of Neurological Issues
Muscle tension from chronic stress affects the neck, shoulders, and back, not to mention more frequent headaches or migraines. The neurological issues associated with compassion fatigue can disrupt sleep patterns, further exacerbating cognitive and emotional issues, along with increasing physical tiredness.
How Compassion Fatigue Affects Patient Care
It is often said that you cannot pour from an empty vessel. The care of a patient is only as good as the well-being of the nurse.
Considering all the effects already discussed, the well-being of the nurses has a direct effect on the level of care we can provide. The numbness mentioned earlier affects the level of empathy we have for our patients. Empathy is the very foundation of what we do. When that is altered, the quality of nurse-patient interactions is affected.
In the same frame, cognitive impairment can have a serious impact on quality of care. Imagine being cognitively impaired as a nurse and having difficulty with memory and decision-making. This can lead to medical errors. For the sake of patient safety, it is important to know how to manage compassion fatigue.
