RESUMEN
OBJECTIVES: This research aims to explore the perceptions of nursing staff regarding the effects of daylighting on behavioral factors including mood, stress, satisfaction, medical error, and efficiency. BACKGROUND: In spite of an extensive body of literature seeking to investigate the impact of daylighting on patients, a limited number of studies have been done for the sake of nurses' perceptions and behavioral responses. METHOD: A mixed-methods approach, comprised of qualitative explorations (structured interviews) and a validated survey, was applied and the results were compared and triangulated. Five nurses were interviewed and 156 nurses volunteered for a lighting survey from six departments of three inpatient facilities in Iran. RESULTS: The findings of this study are consistent with the existing evidence that daylighting and view to the outside enhance nurses' perceptions regarding satisfaction, mood, stress, medical error, and alertness, while reducing fatigue and stress. CONCLUSION: Patient rooms and work stations are the most crucial areas to provide daylighting from nurses' perspectives.
