Abstract

Introduction: Most of health service provider, especially hospitals, require a 24 operational hours of work system. This requires the implementation of a rotating work (Work Shift) system to carry out the demands of its services. Working at noon (morning and afternoon shift) is normal working times according to human physiological conditions, but working at night would impact to the sleep cycle and regulation of human homeostasis. Various studies have found that workers on the night shift have a higher risk of injury or accidents due to work fatigue. Poor sleep quality is one of variable that is directly affected by work shifts that increase on female workers (Akerstedt et.al, 2009). This study aims to determine the impact of the night shift on sleep quality index (SQI) among female workers in Dr. HardjonoS. Hospital. Methods: Data Collected in August 2019 and involved 80 female workers as respondents who were randomly selected using simple random sampling technique. Data were obtained through direct observation and interviews to respondents. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) which resulted in a sleep quality scale. Work shift variables (WS) are divided into : non-night shift (morning, noon) and night shift (morning, noon, night). To find out the differences in physical conditions of workers in each shift, the Heart Rate (HR) of the night shift workers measured in the end of three shifts (morning : 07-14.00; Afternoon : 14.00-21.00; and night :21.00-07.00). Results: Using independent T-test analysis, there was a significant difference in Sleep Quality Index of workers with night shifts and non-night shifts (p < 0.000) with correlation coefficient 0.645. Workers with the night shift has PSQI score 15.155, 30 % higher than workers with non-nigh shift (PSQI Score 11.774). Conclusion: Result shows that working at night decrease in sleep quality index by 30 % than working at day. Workers on the night shift have the highest HR at the end of the shift (86.311 bpm) while workers at noon shift have the lowest HR (85.2).
