Abstract: Objective To investigate the occupational stress and its influencing factors of operating room nurses in hospitals in Jinan City,so as to provide reference for controlling and alleviating the occupational stress of operating room nurses. Methods In March 2021,the occupational stress of operating room nurses in six hospitals in Jinan was investigated,the occupational stress scale（OSI-R）was used to obtain the occupational task score,individual stress response score and individual response ability score of operating room nurses. The demographic data of operating room nurses were collected,and the influencing factors of occupational stress of operating room nurses were analyzed. Results A total of 231 operating room nurses were included. In the OSI- R score,the occupational task score was（183.52±16.98）,the individual stress response score was（105.71±12.36）,and the individual response ability score was（121.53±11.94）.Multiple step-wise regression analysis showed that age （β ’= 1.963）,hospital level （β ’= -2.037）,position title（β’=1.942） and night shift frequency（β’=1.867）were the influencing factors of occupational task scores;education（β’=-1.925）, position title（β’=-2.476）,night shift frequency（β’=2.058）and chronic diseases（β’=2.119）were the influencing factors of individual stress response;age（β’=1.908）,education（β’= 2.017）,working years（β’=2.364）,physical exercise（β’=1.853）and chronic diseases（β’=-1.679）were the influencing factors of individual response ability. Conclusion The occupational stress of operating room nurses in Jinan City is at a high level,and the occupational task,indi- vidual stress response and individual response ability are affected by many factors. Intervention measures should be taken to alleviate the occupational stress of operating room nurses.
