Abstract: Objective To investigate the sources of job burnout among nurses in tumor operating room,and propose corresponding strategies to alleviate job burnout. Methods A total of 72 nurses in tumor operating rooms from Harbin Medical University Cancer Hospital were selected by convenience sampling method from January to March 2023 as survey subjects. General information survey questionnaires,Maslach burnout inventory（MBI） and the Chinese nurse work stressors scale were used to investigate,and the coping methods were explored. Results The average scores of emotional exhaustion sense,indifference sense to work and personal non-achievement sense of 72 nurses in tumor operating rooms were （21.95±5.82）,（5.95±1.82） and （37.98±9.16）points,respectively. 56.94%（41/72） of nurses had a high level of job burnout in the dimension of emotional exhaustion,with a score of ≥19 points. 40.28%（29/72） of nurses had a high level of job burnout in the dimension of job indifference,with a score of ≥6 points. 59.72%（43/72） of nurses had a high level of job burnout in the dimension of personal non-accomplishment sense,with a score of ≤39 points. There were statistically significant differences in job burnout among operating room nurses with different age groups,working years in operating room and daily average effective nursing time（all P<0.05）. The main source of work stress for 72 nurses in tumor operating rooms was worrying about errors and accidents at work,and the secondary sources of work stress were low social status from nursing work and low salary and other welfare. The job burnout of nurses in tumor operating rooms was positively correlated with working years,daily average effective nursing time and work stressors（all P<0.05）. Multiple linear regression analysis showed that age,daily average effective nursing time and work stressors（low social status from nursing work,low salary and other benefits,worrying about errors and accidents in work） could be applied to predict job burnout of nurses in tumor operating room. Conclusion The level of job burnout among nurses in tumor operating rooms is relatively high,especially in those with age ≥35 years and heavy workload. It is necessary to pay attention to the main and secondary work stressors,adjust management methods and strengthen psychological construction for nurses in tumor operating room.
