Abstract: Objective Investigate the current situation and related influences of factors of knowledge, belief and practice of nosocomial infection prevention and control among nurses in non-infectious departments in the isolation ward of novel coronavirus pneumonia. In the context of public health emergencies, nursing managers can formulate and improve the knowledge and information of nosocomial infection prevention and control for non-infectious department anti-epidemic support nurses. It provides a theoretical basis for the intervention strategy at the overall level. Method The self-designed Questionnaire on Knowledge, Confidence and Practice of Nosocomial Infection Prevention and Control of Supporting Nurses in Non-infectious Department was used to investigate the non-infectious department nurses of medical teams in 18 tertiary general hospitals from July 2021, who fought against COVID-19 in the isolation ward of Nanjing Public Health Medical Center. Result 438 questionnaires were sent out and 435 valid questionnaires were recovered, with an effective response rate of 99.32%. The score rates of knowledge, attitude, behavior and knowledge of nosocomial infection prevention and control among 435 anti-epidemic support nurses in non-infection department were 72.82%, 97.39%, 97.36% and 95.15%, respectively. The result of multivariate analysis showed that gender was the influencing factor of knowledge level of nosocomial infection prevention and control, age and the degree of attention of leaders were the influencing factors of attitude level of nosocomial infection prevention and control, and the degree of leadership attention was the influencing factor of behavior level of nosocomial infection prevention and control. Gender, age and leadership attention were the influencing factors of knowledge, belief and practice in nosocomial infection prevention and control (P<0.05). Conclusion The overall level of knowledge, attitude, behavior, knowledge, belief and practice of nosocomial infection prevention and control of anti-epidemic support nurses in non-infection department is high, but the knowledge dimension is still insufficient. Nursing managers can try to start with the factors that affect the level of knowledge, belief and practice of nosocomial infection prevention and control, and take targeted intervention strategies for supporting nurses to ensure that measures for nosocomial infection prevention and control are in place.
