Developing a public health policy-research nexus: An evaluation of Nurse Practitioner models in aged care

•We review literature on research and policy to identify key features for health policy program evaluations.•We use these key features to describe a conceptual framework for complex health policy program evaluations.•We describe the application of this conceptual framework to a current national aged care policy program in Australia.•We propose that using this framework can increase the policy impact of health policy program evaluations.

A frustration often expressed by researchers and policy-makers in public health is an apparent mismatch between respective priorities and expectations for research. Academics bemoan an oversimplification of their work, a reticence for independent critique and the constant pressure to pursue evaluation funding. Meanwhile, policy-makers look for research reports written in plain language with clear application, which are attuned to current policy settings and produced quickly. In a context where there are calls in western nations for evidence based policy with stronger links to academic research, such a mismatch can present significant challenges to policy program evaluation. The purpose of this paper is to present one attempt to overcome these challenges. Specifically, the paper describes the development of a conceptual framework for a large-scale, multifaceted evaluation of an Australian Government health initiative to expand Nurse Practitioner models of practice in aged care service delivery. In doing so, the paper provides a brief review of key points for the facilitation of a strong research-policy nexus in public health evaluations, as well as describes how this particular evaluation embodies these key points. As such, the paper presents an evaluation approach which may be adopted and adapted by others undertaking public health policy program evaluations.
