Abstract/Summary

KEY MESSAGES ● Studies from other sectors demonstrate the potential of a four-day week to improve service quality and efficiency and generate savings. However, benefits may not offset costs in a healthcare setting. ● Absenteeism, high staff turnover, and burnout that reduce service quality and increase healthcare costs are all likely to improve under a four-day week. ● Improved scheduling and team-based productivity could enhance efficiency, helping to maintain or improve delivery. If absenteeism, turnover and errors are reduced, savings may accrue. ● The NHS will need rigorous sector-specific evidence of the potential impact of a four-day week on workforce, service quality and productivity, as well as on its costs, risks and challenges, before considering implementation.
