Compassion Fatigue (CF) is commonly observed in professions associated with human and animal care. The COVID-19 pandemic compelled laboratory animal research institutions to implement new work practices in order to maintain essential animal care operations. These modifications ranged from shift changes to last-resort measures, such as culling animal colonies, to accommodate reduced staffing. Such changes could cause personnel to experience increased stress, isolation, and helplessness-all of which can increase CF risk. In the current study, 200 persons involved with animal research completed an online survey to gauge whether CF among laboratory animal personnel had increased during the pandemic. The survey examined professional quality of life, self-assessed levels of CF, institutional changes, perceived changes in animal welfare, and institutional measures intended to alleviate CF. A total of 86% of participants had experienced CF at some point in their career, with 41% experiencing a CF event (new or worsening symptoms of CF) during the pandemic. In addition, 90% of participants who reported a CF event also reported subsequent effects on their personal or professional lives. Health, employment, and animal-related stress that arose due to the pandemic were all found to influence CF scores significantly. Although 96% of respondents were considered essential workers, 67% did not feel as valued for their work as other essential personnel. Furthermore, 88% of personnel responsible for the euthanasia of healthy animals who experienced a CF event reported that CF also affected their personal life, professional life, or both, and 78% responded that interventions from internal CF programs or leadership did not help to alleviate symptoms of CF. The COVID-19 pandemic and resultant institutional changes will likely have lasting effects on persons and organizations. By determining and subsequently mitigating sources of CF, we can better assist the laboratory animal community during future crises.
