Abstract: Objective To understand the correlation between occupational commitment,perceived stress and work engagement of nurses in operating room of grade-A tertiary hospitals in Nanchang City. Methods From January to June 2022,154 nurses in operating room of three grade-A tertiary hospitals in Nanchang City were investigated by the general information questionnaire,occupational commitment scale,perceived stress scale,and work engagement scale. Results Totally 129 operating room nurses scored （73.19±12.84）points in occupational commitment,（42.53±6.49）points in perceived stress and （64.72±12.62）points in work engagement. The results of correlation analysis showed that the occupational commitment of operating room nurses was negatively correlated with perceived stress（r=-0.969,P<0.01）,and positively correlated with work engagement（r=0.980,P<0.01）. The results of multivariate analysis indicated that age,education level,organizational support,family support,social support,perceived stress,and work engagement were all influencing factors for the occupational commitment of operating room nurses（all P<0.01）. Conclusion The occupational commitment of operating room nurses in grade-A tertiary hospitals in Nanchang City is at a medium level,and improving the perceived stress and salary investment level can enhance the professional commitment level of operating room nurses.
