Holistic sleep improvement strategies for frontline nurses served during a public health emergency (COVID‐19) in Wuhan, China: A quasi‐experimental study

AIM: To examine effects of holistic sleep improvement strategies on frontline nurses who served in Wuhan, China, during a public health emergency (COVID‐19). DESIGN: A pre–post‐test design with single group was conducted with a convenience sample applied the Transparent Reporting of Evaluations with Non‐randomized Designs statement. METHODS: Fifty‐two nurses were recruited from a COVID‐19 designated hospital, receiving holistic sleep improvement intervention, which concentrated on scientific human resource management, comfortable sleep environment establishment, self‐relaxation and self‐adjustment training and humanistic care. Data was collected at baseline and 4‐week follow‐up post intervention using self‐reported questionnaires. RESULTS: The total score of Pittsburgh Sleep Quality Index scale was 8.69 ± 4.346 at baseline. After 4 weeks of follow‐up, the score statistically significantly decreased to 7.48 ± 3.691. Subjective sleep quality (p = .016), sleep efficiency (p = .015), sleep disturbances (p = .007) were statistically significantly improved after the intervention, while there were no statistically significant differences in sleep latency (p = .205), sleep duration (p = .375), sleep medication (p = .723) or daytime dysfunction (p = .747).
