Abstract: Objective To Investigate the information technology pressure,role conflict,and occupational burnout among operating room nurses,explore the impact of information technology pressure and role conflict on occupational burnout,and provide a basis for alleviating occupational burnout. Methods A purposive sampling method was used to survey 194 operating room nurses from 7 grade-A tertiary general hospitals in Shanghai from June to December 2023 using a questionnaire. The information technology stress scale,role conflict scale and job burnout scale were used for investigation,and the data were analyzed. Results The information technology stress score of operating room nurses was （34.28±6.84）points,the role conflict score was （28.46±5.14） points,and the job burnout score was （62.29±12.63）points. The influencing factors of information technology stress,role conflict andjob burnout of operating room nurses were age,years of work,professional title and personal monthly income（all P<0.05）. The information technology stress and role conflict of operating room nurses were positively correlated with job burnout（r=0.574,0.558,both P<0.01）,and information technology stress and role conflict were positively correlated（r=0.566,P<0.01）. Role conflict played a mediating role between information technology stress and job burnout of operating room nurses,with a mediation effect of 0.260,accounting for 44.52% of the total effect. Conclusion Information technology stress and role conflict of operating room nurses are at a high level,and role conflict plays a mediating role between information technology stress and job burnout of operating room nurses. Reducing the level of information technology stress and role conflict is conducive to alleviating job burnout.
