The occurrence of post-traumatic stress disorder (PTSD), job burnout and its influencing factors among ICU nurses.

OBJECTIVE

This study was designed to explore the occurrence of post-traumatic stress disorder (PTSD) symptoms, job burnout and its influencing factors among nurses in intensive care units (ICU).

METHODS

A total of 150 ICU nurses were selected for questionnaire survey by systematic sampling and 143 questionnaires were returned. The questionnaires included a PTSD Checklist-Civilian Version (PCL-C), Maslach Burnout Inventory (MBI), Connor-Davidson Resilience Scale (CD-RISC) and the Social Support Rating Scale (SSRS). ICU nurses were divided into positive and negative groups according to PCL-C scores, the differences between the groups were compared, and the influencing factors for the occurrence of PTSD were analyzed.

RESULTS

ICU nurses had PCL-C scores ranging from 11 to 55 and were divided into the positive group (PCL-C ≥ 38, N=32) and the negative group (PCL-C < 38, N=111) according to the presence of PTSD, with a positive rate of 22.38%. The total MBI scores and scores in emotional exhaustion, depersonalization, and personal accomplishment in the positive group were significantly higher than those in the negative group, (P < 0.05). Health status, years of experience, age, CD-RISC scores, and SSRS scores showed significant difference between the two groups (P < 0.05). Multivariate logistic regression showed that MBI score was an independent risk factor for the development of PTSD symptoms among ICU nurses (OR > 1, P < 0.05), while CD-RISC score was a protective factor (OR < 1, P < 0.05).

CONCLUSION

The incidence rate of PTSD among ICU nurses was 22.38%, and MBI score and CD-RISC score were independent influencing factors for the occurrence of PTSD symptoms.
