The Effects of Lighting, Lactic Acid Levels, and Occupational Factors on Performance of Nurses, With Work Fatigue at Latemmamala Regional Hospital

Introduction: Nurse performance can decline due to complaints of work fatigue. Fatigue can occur due to both internal and external factors. Methods: This study used a quantitative cross-sectional approach. The sampling technique used probability sampling resulted in 160 respondents. Results: Lighting (p = 0.002 < 0.05), Lactic Acid (p = 0.000 < 0.05), physical workload (p = 0.000 < 0.05), length of work (p = 0.020 < 0.05), subjective work fatigue (p = 0.000 < 0.05), and objective work fatigue (p = 0.000 < 0.05) had a significant effect on nurse performance, while work shift (p = 0.082 > 0.05) had no effect. In multivariate analysis, the indirect impact of physical workload on nurses' performance through objective work fatigue showed a significant influence.(p = 0.001 < 0.05) and length of work on nurse performance through objective work fatigue had a significant effect (p = 0.011 < 0.05). Conclusions: Physical workload and length of work have an indirect effect on nurse performance through work fatigue. or unstructured, no longer than 250 words; written in the past tense and in the third person singular.
