Objective  To investigate the fatigue and sleep status of medical staff in a top tertiary general(Grade Ⅲ with A level) hospital, so as to provide orientation for the development of physical and mental health services for medical staff.

  Methods  In August 2021, a questionnaire survey was conducted among 1 009 medical staff from a top tertiary general hospital in Beijing by convenient sampling. The Pittsburgh sleep quality index (PSQI) and Fatigue index - 14 (FS-14) were used to investigate the sleep quality and fatigue of the subjects. The influencing factors of sleep disorder and fatigue were analyzed by multivariate logistic regression model.

  Results  Totally 1 001 valid questionnaires were recovered with the effective recovery rate of 99.20%. The total average score of PSQI was (7.43±3.69), and the average sleep time was (6.25±1.09)h and 44.86% of them had sleep disorders. Totally 520 cases were judged as fatigue, with the average score of FS-14 was(7.31±3.77), and the incidence rate was 51.95%. The results of logistic regression analysis showed that: (1) Compared with personnel working in departments of internal medicine, the medical staff working in emergency departments(OR=1.78)and departments related to severe diseases(OR=2.21)were more likely to have sleep disorders (P < 0.05).(2) Compared with medical staff without stress, medical staff who often feel stressed were more likely to have sleep disorders and fatigue (OR=4.295, 5.646, P < 0.05).(3) Compared with medical staff with college degree and below education level, medical staff with graduate degree and above were less likely to have sleep disorders (OR=0.565, P < 0.05).(4)Compared with the medical staff with poor self -perceived health status, the medical staff with moderate self-perceived health status were less likely to suffer from sleep disorders and stress (OR=0.036 - 0.242, P < 0.05). (5) Compared with the medical staff working in the main urban area, the medical staff working in the sub central area were less likely to suffer from fatigue (OR=0.622, P < 0.05).(6) Compared with medical staff working less than 40 hours per week, medical staff working more than 50 hours a week were more likely to suffer from fatigue (OR=2.217, 1.593, P < 0.05).(7) Compared with the medical staff with employment time less than 5 years, the medical staff with employment time for 11 to 20 years were more likely to suffer from fatigue (OR=2.095, P < 0.05)(. 8) Compared with medical personnel who exercised less than 2 times a week, medical personnel who exercised more than 2 times a week were less likely to experience fatigue (OR=0.681, P < 0.05). All items of PSQI were positively correlated with physical fatigue, mental fatigue and total fatigue scores of FS -14 (P < 0.05).

  Conclusions  Fatigue and sleep quality problems were common among medical staff in this top tertiary general hospital in Beijing. We should improve the working environment, pay attention to physical and mental health, provide psychological support and other comprehensive measures to alleviate the fatigue and sleep problems of these medical personnel. Scientific staffing and workload balance should be done. The sleep education and a good working environment should be provided to improve the physical and mental health of medical personnel.
