Creating healthy hospital retail food environments: Multiple pathways to successful at scale policy implementation in...

In 2017, the Australian state of New South Wales introduced a revised policy to provide a healthy food and drink environment for staff and visitors in the state's publicly funded health facilities. We sought to understand how contextual factors, intervention features and the responses of diverse stakeholders affected the policy's implementation in public hospitals.

Ninety-nine interviews were conducted with chief executives, implementers and retailers in the health and food retail systems after the target date for the implementation of 13 initial policy practices. Stakeholder responses were analysed to understand commitment to, engagement with and achievement of these practices and the different contexts and implementation approaches that prompted these responses.

Key mechanisms that drove systemic change included stakeholders' broad acceptance of the policy premise; stakeholders' sense of accountability and desire for the policy to succeed; and the policy's perceived benefits, feasibility and effectiveness. Important underpinning factors were chief executives' commitment to implementation and monitoring, a flexible approach to locally tailored implementation and historical precedents.

This study provides policy and practice insights for the initial phase of state-wide implementation to achieve change in health facility food retail environments.
