Realist review as a methodology for using evidence in health policies: An integrative review

Abstract

Objective: To identify and analyze the concepts of realist review and the recommended methodology for its development in the health area. Method: An integrative review which sought theoretical-methodological qualitative or quantitative studies through 11 data sources which analyzed or proposed theories and/or realist review methodology. Results: Twenty-three (23) studies, mainly published in the United Kingdom, were included. The realist review aims at explaining what makes a complex policy, program, or intervention work, in which aspects, for whom, in what context, to what extent, and why, by constructing theory, decompressing the functioning mechanisms, complex policy contexts or programs which generate results. Such methodology relies on the involvement of stakeholders in the problem from the early stages of the review process. Conclusion: The realist review has the potential to provide relevant and applicable subsidies for researchers, workers, policy makers and health decision makers.
