Choi and Kim: The Impact of Safety Climate and Fatigue on Safety Performance of Operating Room Nurses



This study was conducted to evaluate the level of safety climate, fatigue, and safety performance and to identify the impact of safety climate and fatigue on the safety performance of operating room nurses.


The study design was a descriptive survey. Participants were 174 operating room nurses from two general hospitals and two university hospitals in S and D cities. Three structurally designed questionnaires were used to evaluate their safety climate, fatigue, and safety performance. Collected data were analyzed using descriptive analysis, t-tests, ANOVAs, Pearson correlation coefficient, and stepwise multiple regression.


Safety performance of operating room nurses had a mean of 3.26 on a 5-point scale. ‘Current department career’(β=.17, p=.006) and ‘safety climate (work-unit contribution) (β=.63, p<.001) accounted for 39% of the variance in operating room nurses’ safety performance.


Findings indicate that work-unit contribution towards safety climate is an important factor in increasing operating room nurses' safety performance. Therefore, it is essential to find motivational properties consistent with the characteristics of the operating room environment.
