ANALYSIS OF THE EFFECT OF WORKLOAD, WORK SHIFTS AND SLEEP QUALITY ON WORK PRODUCTIVITY THROUGH JOB FATIGUE IN NURSES AT BATARA GURU REGIONAL GENERAL HOSPITAL, LUWU REGENCY.

Abstract

Background. Workload, work shifts and sleep quality are several important factors that trigger fatigue in a nurse which ultimately contributes to nurse work productivity. Objective. This study aims to analyze the influence of workload, work shifts and sleep quality on work productivity through work fatigue in nurses at Batara Guru Regional Hospital, Luwu Regency. Method. This research uses a quantitative approach with a cross-sectional design. The sample consisted of 200 nurses as respondents who were selected using the Probability Random Sampling technique. Data collection was carried out using a questionnaire involving variables such as workload, work shifts, sleep quality, work fatigue and work productivity. Results. The analysis revealed that workload had no significant direct impact on work fatigue (P = 0.787) or productivity (P = 0.862). In contrast, shift work exhibited a significant positive direct effect on work fatigue (estimate = 0.518, P = 0.003) and a significant negative direct effect on work productivity (estimate = -0.466, P = 0.000). Meanwhile, sleep quality has a significant positive direct influence on work fatigue (estimate = 0.616) & (P = 0.004) and has a significant negative direct influence on work productivity (estimate = -0.600) & (P = 0.000). Through job tiredness, workload does not have an indirect impact on productivity, according to indirect influence results (P=0.768). In the meantime, work tiredness (P=0.006) and (P=0.001) are indirect effects of work shifts and quality on work productivity. Conclusion. Work shifts and sleep quality significantly impact work fatigue and work productivity directly. They also indirectly affect work productivity through work fatigue. In contrast, workload neither directly influences work fatigue and productivity nor indirectly impacts productivity through work fatigue.
