Abstract: Objective To investigate the current status of technical stress,psychological capital and job burnout of operating room nurses,study the effects of technical stress and psychological capital on job burnout of operating room nurses,and provide reference for reducing the level of occupational burnout. Methods A cross-sectional survey method was used to investigate and analyze 176 operating room nurses from 13 grade-A tertiary hospitals in Hubei Province from May to July 2024 using the general situation scale,technical stress scale,psychological capital scale and job burnout scale. The differences in technical stress,psychological capital and job burnout scores were compared among different demographic characteristics. The correlation between technical stress,psychological capital and job burnout of operating room nurses was analyzed. The mediation test procedure was used to analyze the mediating effect of psychological capital between technical stress and job burnout of operating room nurses. Results The technical stress score of operating room nurses was （74.29±14.28）points,the psychological capital score was （92.35±15.47）points,and the job burnout score was （60.26±12.57）points. The differences in the scores of technical stress,psychological capital and job burnout were statistically significant among operating room nurses in different age,years of work,professional title,marital status,average monthly income,average number of monthly night shifts and average weekly working hours（all P<0.05）. The higher the level of technical stress of operating room nurses,the higher the level of job burnout（r=0.642,P<0.01）. The higher the level of psychological capital of operating room nurses,the lower the level of job burnout（r=-0.586,P<0.01）. The higher the level of psychological capital of operating room nurses,the lower the technical stress（r=-0.592,P<0.01）. The psychological capital of operating room nurses had a partial mediating effect between technical stress and job burnout（mediating effect value was 0.239）,accounting for 40.78% of the total effect. Conclusion The technical stress and job burnout of operating room nurses are at a high level. The psychological capital has a partial mediating effect in the effect of technical stress on job burnout of operating room nurses. Further improving psychological capital on the basis of reducing technical stress is helpful to alleviate the job burnout of operating room nurses.
