Abstract
BACKGROUND: Sleep of inadequate quality, duration or regularity has potential negative physical and mental health outcomes. The impacts of poor sleep within the paramedic occupation are not well understood. AIMS: This review aimed to determine the prevalence of insomnia, excessive daytime sleepiness and poor sleep quality amongst paramedics, and to identify any relationships between insomnia, excessive daytime sleepiness, poor sleep quality and other health-related outcomes. METHODS: A systematic search identified studies that measured excessive sleepiness, insomnia or poor sleep quality using validated measures. The population was limited to paramedics in Australia, New Zealand or the UK owing to the similar nature of the workload, education standards, shift patterns and scope of practice. RESULTS: Four studies were included. All used the Pittsburgh Sleep Quality Index, two used the Epworth Sleepiness Scale and one used the Insomnia Severity Index. Sample sizes ranged between 60 and 342. The weighted mean prevalence of excessive daytime sleepiness was 30 %, and poor sleep quality reported as 71%. Only one study measured the association between sleep and other health-related outcomes; this study reported an association between sleep quality and multiple measures of mental health. CONCLUSIONS: The findings of this review suggest that paramedics experience both poor-quality sleep and excessive daytime sleepiness, and further suggest that there may be an association between poor sleep quality and mental health. Given sleep impacts a variety of health outcomes, as well as impacts work performance, research on the specific components of sleep is important.
