Insomnia, Sleepiness, and Fatigue Among Polish Nurses

Background: Sleep disorders can result in sleepiness, fatigue, and apathy, and may contribute to serious occupational consequences such as errors at work. The aim of the study was to examine the level of insomnia, sleepiness, and fatigue in a sample of Polish nurses. Methods: The research was conducted among nurses employed in the Lublin region of Poland. A sample of nurses were invited to participate in a survey in which we measured insomnia, sleepiness, and fatigue using the Athens Insomnia Scale (AIS), the Epworth Sleepiness Scale (ESS), and the Fatigue Severity Scale (FSS). Findings: Among the 200 nurses that were surveyed, 141 (70.5%) responded. The findings indicated that a total of 47.8% of the surveyed nurses reported insomnia. Half (50.0%) exceeded the threshold for fatigue relative to the general population. Although no differences in fatigue and sleepiness were observed by level of insomnia between those who did and did not work night shift, we observed an overall correlation between insomnia (AIS) and sleepiness (ESS), as well as between insomnia (AIS) and fatigue (FSS). Conclusions/Application to practice: This sample of Polish nurses displayed problems with sleep quality. The consequences of insomnia and fatigue challenge occupational health workers to go beyond traditional care and standard diagnostic tests. Undertaking preventive measures aimed at reducing health hazards, and the risk of making a mistake at work due to increased sleepiness and fatigue, in nurses are warranted.
