The relationship between compassion fatigue and nursing working environment in emergency department nurses in tertiary hospital: A cross-sectional study

Emergency nurses in Yunnan Province generally suffer from high compassion fatigue, affected by multiple factors such as local cultural diversity and seasonal wild mushroom poisoning. A supportive work environment is significantly associated with lower compassion fatigue, highlighting the urgency to optimize the workplace. Future research should use longitudinal and mixed-method designs to explore seasonal dynamic changes and develop targeted interventions adapted to Yunnan's regional features, so as to alleviate compassion fatigue, improve nurses' mental health, and enhance patient care quality.
