Abstract: Objective: To investigate the self-efficacy and knowledge-sharing behavior of pressure injury management among nurses in operating rooms and to analyze the influencing factors of self-efficacy. Methods: From May to July 2022, a total of 591 nurses in operating rooms were selected from 25 hospitals in 13 provinces including Henan, Hunan and Jiangxi by convenience sampling. The general information questionnaire, the Nurse Stress Injury Management Self-efficacy Scale and the Clinical Nurse Knowledge- Sharing Behavior Scale were used. Results: Among 591 nurses, the average score of self-efficacy in pressure injury management was (3.73±0.81), and the average score of knowledge-sharing behavior was (2.82±0.88). The score of self-efficacy was significantly positively correlated with the score of knowledge-sharing behavior (r=0.515, P<0.001). The results of multiple linear regression analysis showed that the influencing factors of self-efficacy were hospital level, the total number of pressure injury knowledge training, the establishment of pressure injury group and knowledge-sharing behavior (all P<0.05). Conclusion: The self-efficacy of pressure injury of nurses in operating room is above the medium level, and the knowledge-sharing level is at the medium level. The higher the self-efficacy level, the stronger the knowledge-sharing level will be. It is suggested that nurse managers in operating rooms should carry out targeted intervention according to its influencing factors to improve the self-efficacy and knowledge-sharing behavior of nurses in the management of pressure injury. By this way, the incidence of perioperative pressure injury will be reduced and the quality of nursing will be improved.
