Compassion fatigue is caused by the overwhelming sensations of compassion and empathy one may feel when caring for individuals suffering from acute or chronic illness, disasters, or other traumatic events. It may also occur in response to vicarious trauma, which is the emotional toll experienced by a caregiver when caring for an individual who has experienced trauma. Compassion fatigue is particularly prevalent within the healthcare industry; however, individuals in various other professions may also carry the risk of experiencing compassion fatigue. The various professions include healthcare workers, child protection workers, veterinarians, clergy, teachers, social workers, palliative care workers, journalists, police officers, firefighters, paramedics, animal welfare workers, public librarians, and student affairs professionals. Additionally, non-professionals, including family members and informal caregivers of those with chronic illnesses, may also encounter compassion fatigue.
Several factors contribute to an individual's susceptibility for compassion fatigue, including insufficient support systems and an inclination to avoid one’s
emotions. Organizational flaws within high-risk fields, such as healthcare, contribute to compassion fatigue among workers. For example, a "culture of silence," where distressing events such as deaths within intensive care units are not openly discussed, has been linked to compassion fatigue. Lack of awareness regarding symptoms and inadequate training regarding the risks associated with high-
stress occupations also contribute to high rates of compassion fatigue. Rates increase with prolonged exposure to individuals in need. For example, homelessness can be more prevalent in large urban areas, resulting in more urban dwellers developing compassion fatigue.
