An overview and comparison of approaches used for health policy analysis: What to use and when?

Abstract Background Public health challenges are complex and analyzing them requires advanced approaches such as, societal cost-benefit analysis (SCBA), health impact assessment (HIA), and strategic foresight. Analyzing health policy is a multifaceted process, and depends on, among others, the scope, approach, and policy goals. Given this complex and multifaceted nature, it is not always clear which approach to use, and how the approaches can complement each other. Therefore, health policy analysis could benefit from practical and explicit guidance regarding clear identification of cases and types of analysis. Hence in this paper we aim to develop a framework that can provide this guidance. Methods In this paper we describe the differences and similarities of three distinct health policy assessment approaches, SCBA (an economic evaluation approach that takes into account the impact on society as a whole), HIA (is a combination of tools that focus on evaluating the potential health effects of a given policy) and strategic foresight (a systematic and participatory approach used to anticipate and plan for future trends and uncertainties that may impact policy), their application, and how they can complement each other within the field of public health. A framework that can be used when deciding which health policy approach to use for a given case will be developed, based on existing literature, frameworks, and a case study. Discussion This paper contributes to knowledge on health policy analysis and towards efficiency and clarity in analyses conducted in this field. Key messages • There is little guidance regarding how to conduct health policy analysis. • Clear guidance on which approaches to use and how they complement each other will contribute towards efficiency and clarity in health policy analysis.
