Résumé
OBJECTIVE@#To study the working experience of COVID-19 care nurses.@*METHODS@#Twenty two nurses taking care of COVID-19 patients were interviewed by means of descriptive phenomenology. All the data were transcribed and recorded, and then processed into WORD documents. The Colaizzi 7 footwork was used to classify, encode, establish nodes and extract themes based on Nvivo11.0 software.@*RESULTS@#Two main themes were extracted: one is the positive feelings of nurses, including the sense of professional mission and pride, the sense of achievement and happiness, the improvement of self-worth and ability, the powerful support system and the power of role models; the other is the negative experience of nurses, including the worry and anxiety at work, the lack of experience and trust, the difficulty of work, and the inconvenience of isolating life.@*CONCLUSIONS@#s While fully affirming the work value of nurses, it is necessary for the society, hospitals and patients to give extensive and continuous support, care and respect to nurses, so as to stimulate their working enthusiasm and sense of professional achievement. Hospital managers need to implement all kinds of security work, meet the safety needs of nurses, pay attention to the physical and mental health of nurses, strengthen the training of nursing talents for critical and severe diseases and infectious diseases, improve the allocation of human resources, and enhance the ability of material allocation and reserve for major health events, so as to make adequate preparations for coping with public health events in the future.
