Abstract: Objective: To investigate the status quo of nurses' knowledge about the prevention and control of catheter-related infection, so as to provide reference for improving nurses' knowledge about the prevention and control of catheter-related infection. Methods: From July 12 to August 12, 2023, a self-designed questionnaire on prevention and control of catheter-related infection was used, and the questionnaire was distributed to clinical nurses, nursing managers and full-time nursing staff through the platform of the Infection Prevention and Control Committee of Chinese Nursing Association. Results: Among the 11 questions, there were 5 questions with 50% correct answers and only 3 questions with 80% correct answers. The highest correct rate is the disinfection method of infusion joint (97.49%), and the lower correct rate is the dilution of normal saline before sputum aspiration (19.80%), the cleaning and disinfection of indwelling catheter (19.06%), the regular air bag deflation of patients with tracheal intubation (15.51%), and the bladder function exercise before pulling out the catheter (9.97%). There was statistical significance in comparing the length of service, professional titles and positions of nurses in hospitals with different grades (P<0.05). Conclusion: Nurses' practical knowledge of prevention and control of catheter-related infection needs to be improved, and evidence-based ability and related knowledge training need to be strengthened.
