Sleep quality analysis of Chinese medical civilians in the Subtropics during different stages of deployment

Abstract

Abstract Background: Inadequate sleep and poor sleep quality have been linked to higher incidences of major industrial and workplace accidents. They also have been associated with poorer health outcomes, such as increased risks of obesity, diabetes, cardiovascular disease, neurogenerative diseases, and poor mental health. Therefore, it is important to ensure adequate sleep and good sleep quality to promote the physical and mental wellbeing of individuals. The aim of this study was to analyze the sleep quality of medical civilians participating in a medical emergency rescue exercise, which involved travelling long distances on a train. Methods: We used the Pittsburgh Sleep Quality Index (PSQI) to measure the sleep duration and sleep quality during four different phases of the exercise, namely the training phase (T1), travel phase (T2), official task phase (T3), and quarantine phase (T4). Results: The mean sleep durations during each phase were 6.678 h (T1), 6.64 h (T2), 6.41 h (T3), and 7.06 h (T4), and the mean PSQI score of the sleep quality across all four phases was 4.43. The highest proportion of sleep disturbance occurred during the travel phase (c2=477; p<0.001). The nonmedical team members had a longer sleep duration and a better sleep quality compared to those of the medical team members (p<0.05). Conclusion: Our study demonstrated that medical civilians experience a shorter sleep duration and a poorer sleep quality during deployment. Interventions such as lowering acute stress levels and workload, promoting good sleep hygiene and attitudes towards sleep, and improving the sleep environment may help to improve the overall sleep quality of medical team members.
