Abstract Introduction This study evaluates the effectiveness and implementation of PerfectFit@Night, an intervention to improve sleep, fatigue and recovery of night workers in healthcare. Methods PerfectFit@Night was implemented at twelve hospital departments that moved from the control to the intervention condition with two questionnaire measurements before and two measurements after the intervention. PerfectFit@Night lasted at least 3 months, and consisted of individual components (i.e., e-learning modules and targeted sleep coaching) and environmental elements (i.e., taking naps by using a powernap bed, healthy food provided during night shifts and a workshop on healthy rostering). The primary outcomes were sleep (night shift-related insomnia, sleep quality, sleep duration), fatigue and need for recovery. Mixed model analyses were performed to measure the outcomes over time. The implementation process was evaluated using the framework of Steckler and Linnan based on quantitative and qualitative data. Ethical approval was obtained. Results The first preliminary results showed that after three and six months of the intervention, the prevalence of night shift-related insomnia decreased with 11% (95% CI: -0.19, -0.04) and 13% (95% CI: -0.22, -0.05) respectively, while no effects were found for sleep quality and duration. After six months, the likelihood of more fatigue decreased (OR: 0.51, 95% CI: 0.28, 0.94) and the need for recovery decreased (β: -2.45, 95%CI: -4.86, -0.03). Discussion The final results of the analyses as well as the implementation of the intervention will be presented at the conference. Conclusion The preliminary results showed that PerfectFit@Night showed promising results for improving sleep, fatigue and recovery of night workers in healthcare.
