Introduction: Many studies have indicated that stress and fatigue among hospital staff are one of the influencing factors that affect medication errors, staff performance and could reduce hospital safety. This study aimed at investigating the impacts of environmental factors on staff's stress and fatigue and provides designing approaches for minimizing these factors.
Material and Method: In this descriptive cross-sectional survey, 126 hospital staff were chosen randomly from four hospitals in the city of Tehran and questionnaires were distributed among them. Data were analyzed using SPSS 22, which included descriptive statistics, Friedman and chi-square test.
Results: According to the results, 90.5 percent of respondents described their working environment as stressful and 64.3 percent stated that physical environment makes them tired. The results revealed that among the 11 environmental variables that negatively affect stress, noise, light and spatial layout ranked one to three according to the degree of their influence. Moreover, among the 11 variables that cause fatigue in working environment, noise, light and the location of nursing station ranked one to three based on their impacts.
Conclusion: The results showed that the physical environment has a great impact on most of hospital staff. Noise and light have the great impact on both of stress and fatigue and we can improve the hospital environment through proper lighting design and reducing design.
