Objective:To investigate the level of Posttraumatic Stress Disorder Symptom (PTSDS) of operating room nurses in tertiary hospitals of Jinan, and to explore the relationship between PTSDS and traumatic events, resilience, job burnout, childhood trauma and other demographic factors, in order to improve physical and psychological health of operating room nurses.Methods:216 operating room nurses of tertiary hospitals in Jinan were administered questionnaires by cluster sampling method, and the response rate was 83.08%. Six instruments included general information questionnaire, Operating Room Nurse Traumatic Events Scale, the Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C), the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Maslach Burnout Inventory (MBI) and the Connor-Davidson Resilience scale (CD-RISC). All data obtained were statistically analyzed by software package SPSS16.0 for windows. Statistical methods such as completely randomized design analysis of variance (ANOVA), independent T test,x test, correlation analysis and multiple liner stepwise regression were used to assess the questionnaire.Results:1. The mean score of PTSD was 30.32±9.90 and the score of subscales Re-experiencing the trauma, Avoidance behaviors and Hyper-arousal behaviors was 9.41±3.23,11.63±4.25 and 9.28±3.56 respectively.21 out of the 216 objects were detected to be positive PTSD symptoms, and the positive rate was 21.3%.2. The prevalence of negative life event was 64.4% and the operating room nurse traumatic event was 95.8%.3. There were statistically significant differences of PTSDS in different groups divided by hospital, age and period of operating room service (P<0.05).4. There were statistically significant differences of PTSDS in different levels of operating room nurse trauma (P<0.01).5. The correlation analysis showed that there were positive relations between PTSD and trauma events, childhood trauma and job burnout (P<0.05,P<0.01).6. The main influential factors of PTSDS in operating room nurse were traumatic events(b'=0.369), emotional exhaustion (b'=0.251), depersonalization (b'=0.178) and sexual abuse (b'=0.121) and the percentage of variance explained was 40.2%.Conclusion:1. It was serious that the PTSDS of operating room nurses in the third class of hospital of Jinan, and the influential factors were traumatic events, emotional exhaustion, depersonalization and sexual abuse.2. Traumatic event was significantly related to the PTSDS and the more the trauma, the more serious the PTSDS. The most related factors of the PTSDS were the colleagues bullying, rescue the knife hacked patients and the doctor's reproach.3. The operating room nurse with higher level of job burnout had more serious PTSD. More attention should be taken to the relationship between the job burnout and PTSD.4.
