| dc.description.abstract | Work fatigue is a significant issue in occupational health and safety, especially among healthcare workers in emergency departments (ED) who operate under high-pressure conditions. Based on preliminary interviews with eight nurses, it was found that seven frequently experienced a lack of fitness after completing their shifts, with complaints such as headaches, digestive disturbances, and loss of appetite. These symptoms are indicative of work fatigue, suggesting that nurses in the Emergency Department of Haji General Hospital Medan may be experiencing fatigue. This study aims to identify factors associated with work fatigue among ED nurses at Haji General Hospital Medan in 2025. A quantitative approach with a cross-sectional design was used. The population and sample consisted of all 34 ED nurses at the hospital. The independent variables studied included physical work intensity, mental work intensity, circadian rhythm, health status, and nutritional intake. Data were collected using various tools: a reaction timer for measuring fatigue, an oximeter for physical work intensity, the NASA-TLX questionnaire for mental workload, the Pittsburgh Sleep Quality Index (PSQI) for circadian rhythm, a 24-hour food recall for nutrition, and a health condition questionnaire. Data were analyzed using the Spearman rank correlation test. The results showed significant relationships between work fatigue and physical work intensity (p=0.002), mental work intensity (p=0.014), circadian rhythm (p=0.001), nutritional status (p=0.020), and health condition (p=0.001). Most nurses were found to experience moderate levels of work fatigue, totaling 13 individuals (38.2%). These findings indicate that work fatigue among ED nurses is influenced by physical and mental work intensity, circadian rhythm disturbances, inadequate nutrition, and poor health status. It is recommended that nurses maintain their health, balance activity with rest, manage work-related stress, and improve their nutritional intake to prevent fatigue. | en_US |
