Designing the work week in healthcare: a systems agenda for safer, sustainable work

Healthcare systems internationally face persistent workforce shortages, rising burnout and increasing concerns regarding patient safety. While these challenges are often addressed through staffing, resilience or wellbeing initiatives, less attention has been paid to the temporal architecture through which healthcare work is organised. This paper argues that fatigue represents a systems-level signal of maladaptive temporal design rather than an inevitable consequence of clinical work and proposes temporal governance as a novel framework for redesigning healthcare work.

An integrative review was undertaken combining evidence from empirical studies, policy evaluations, organisational pilots and systems theory. International working-time reduction initiatives published between 2015 and 2025 were identified through targeted searches of academic databases, government reports and grey literature. Cases were analysed comparatively to identify recurring mechanisms linking temporal redesign with workforce and organisational outcomes.

Across heterogeneous international settings, reductions in working time were consistently associated with improvements in workforce wellbeing, lower burnout, reduced sickness absence, improved retention and preservation or enhancement of organisational performance. Four convergent mechanisms emerged across studies: physiological recovery, cognitive clarity, temporal autonomy and organisational focus. These mechanisms provide a plausible systems-level explanation for how redesigning working time can simultaneously improve human sustainability and organisational effectiveness. Drawing upon complexity science, the paper proposes a mechanism-based theory of change in which temporal redesign stabilises reinforcing fatigue loops and strengthens adaptive capacity within healthcare systems.

Fatigue should be understood not solely as an occupational health issue but as an indicator of systemic temporal imbalance. Working-time redesign offers a promising governance intervention capable of improving workforce sustainability while maintaining organisational performance. Rather than framing shorter working hours as a workforce benefit alone, healthcare organisations should recognise time as critical infrastructure that can be intentionally designed, governed and evaluated as a core patient safety variable. Future research should determine the optimal temporal architectures for different healthcare contexts and establish time as a measurable dimension of healthcare quality and safety.
