Critical care nurses are often exposed to many stressors, which may predispose them to develop work-related Post-Traumatic Stress Disorder (PTSD). Hence, this study's purpose was to identify factors associated with PTSD among nurses in the Intensive Care Unit (ICU), who had experienced trauma events.
For this descriptive study, 169 subjects were recruited at the C University Hospital, where data were collected through the intranet from February 1 to March 16, 2018. Based on the stress, appraisal-coping model, well-structured questionnaires were used to measure PTSD as the dependent variable; and Type D personality, resilience, communication ability, problem solving ability, stress coping style, stress inducing events, and social support as independent variables. Multiple logistic regression was used to analyze PTSD related factors.
The mean of PTSD symptoms was 15.52±12.94; with 20.7% and 45.6% of participants falling in the PTSD high risk and Type D personality groups, respectively. Moreover, resilience was found to be 107.41±12.79, traumatic events to be 28.25±7.07, and social support to be 80.22±12.20, while the following parameters were associated with PTSD: D type personality (Odds Ratio [OR]=4.27, 95% Confidence Interval [CI]=1.62~11.21), experience of traumatic events (OR=1.08, 95% CI=1.02~1.15), resilience (OR=0.96, 95% CI=0.92~0.99), and social support (OR=0.96, 95% CI=0.92~0.99).
While examining risk factors associated with PTSD, Type D personality and the occurrence of trauma events should be considered when nurses are assigned to ICUs, along with the improvements required in hospital culture for enhancing resilience and social support.
