Abstract: Objective To investigate the incidence of sleep disorders among operating room nurses in grade A tertiary hospitals in Shanghai and analyze its related factors. Methods In July 2023, all operating room nurses in 8 grade A tertiary hospitals in Shanghai were included for this study. The General Information Survey Questionnaire, Nurse Job Stress Inventory, Job Content Questionnaire (JCQ), and Pittsburgh Sleep Quality Index (PSQI) were applied to conduct surveys on them. The incidence of sleep disorders among operating room nurses with different characteristics was compared, and logistic regression was applied to screen for influencing factors of sleep disorders among operating room nurses. Results This study ultimately included 426 operating room nurses, of whom 13.85% were male and 86.15% were female, with an average age of (37.58±5.26) years and an working experience of (12.46±4.13) years; the proportion of college education was 50.94%, and the proportion of bachelor degree or above was 49.06%; the proportion of junior nurses was 33.10%, the proportion of senior nurses was 37.09%, and the proportion of supervising nurses and above was 29.81%. Sleep disorders occurred in 242 cases (56.81%). The risk factors for sleep disorders among operating room nurses mainly included age of 28-<40 years (OR=3.016), working experience of 5-<10 years (OR=2.986), complicated with chronic diseases (OR=2.936), average monthly night shift frequency >5 times (OR=2.719), moderate or severe work pressure (OR=2.412, 3.084), and high occupational stress (OR=2.815), the protective factor was regular exercise (OR=0.406). Conclusions The incidence of sleep disorders among operating room nurses in grade A tertiary hospitals in Shanghai is relatively high, especially among age of 28-<40 years, working experience of 6-<10 years, complicated with chronic diseases, average monthly night shift frequency >5 times, moderate or severe work pressure, and high occupational stress. Therefore, effective strategies should be taken to intervene in the sleep of operating room nurses, and encourage them to carry out regular exercise to improve sleep disorders.
