The effects of resident work hours on well‐being, performance, and education: A review from a Japanese perspective

Abstract

AbstractThis article examines the impact of working‐hour restrictions on the well‐being, performance, and education of medical residents in Japan. Despite Japan's plan to introduce new regulations for resident working hours by 2024, there is still an ongoing debate regarding their appropriateness. This review provides a comprehensive overview of the current regulations of resident working hours worldwide, with a specific focus on weekly hours. The varying regulations are highlighted, including the 80‐hour‐per‐week regulation in the United States and the 48‐h‐per‐week regulation in the European Union influencing other regions. The article also discusses the effectiveness of working‐hour restrictions on residents' mental health, with shorter working hours having potentially greater benefits. However, the impacts on medical safety and resident education are mixed, and further reduction in working hours must be carefully considered to avoid adverse effects. The planned changes to working‐hour limits for residents in Japan offer a unique opportunity to gain new evidence on the impact of such regulations, which will be of interest to policymakers and researchers worldwide.
