Objective:To explore the psychological experience of front-line nurses combating the COVID-19 epidemic and provide suggestions and evidence for clinical interventions.Methods:From January 25th to 27th, 2020, a semi-structured interview was conducted using phenomenological research methods on 10 front-line nurses combating COVID-19 from a Class Ⅲ Grade A hospital, and Giorgi phenomenological analysis was used to analyze the data.Results:The psychological experience of clinical front-line nurses in this study could boil down to three themes: negative psychological experience (fear, worry, and fatigue) , insufficient ability to cope with public health emergencies (insufficient awareness of disease, and insufficient emergency rescue nursing skills) , and rational understanding of the fight against the epidemic (a sense of mission and confidence) .Conclusions:Clinical front-line nurses have different levels of negative psychological experience and lack the ability to respond to public health emergencies. Hospitals should strengthen psychological assistance and humane care for clinical front-line nurses, promote training for emergency disaster rescue nursing, improve hospital emergency management capabilities, and ensure efficient rescue work.
