Managers and clinicians: Perceptions of the impact of regionalization in two regions in Canada

The aim of this paper is to examine the approach taken to regionalization in Ontario, Canada, and its impact on health system performance as perceived by managers and clinicians.

Our findings demonstrate that both sets of actors see regional structures as contributing significantly to improving their respective health system although they also identify areas that require improvement. Managers and clinicians agreed on propositions to focus on health determinants, major considerations specific to the local context (population, geography) and support for a three-level system with well-defined functions. However, they also expressed differing propositions about the political power of hospitals
