Abstract: (2162 Views)
Background and Aim: The realist review has been introduced to review and synthesize the evidence related to the implementation of complex healthcare interventions. This method interprets the results of an intervention by explaining the causal relationships between the intervention and the results. This study aimed to explain the methodology of realist review in the health system.
Materials and Methods: This study was conducted using the scoping review. The following databases were used to find articles using appropriate search strategies and relevant key words: Pubmed, Scopus, Science Direct, and Embase electronic databases, as well as Google Scholar and Google search engines. Finally 49 articles were selected (in the period between January 1990 and December 2020) for review.
Results: The realist review is a theory-based approach to synthesize evidence related to the complex interventions, explaining the reasons for the successes or failures of interventions based on the causal relationships between the interventions, contexts, mechanisms and outcomes. A protocol was introduced to conduct a realist review composed of three phases ─ explaining, development and correcting the intervention program theory ─ and including seven steps of determining research questions; explaining the initial program theory; developing search strategies; collecting, evaluating and selecting evidence; synthesizing evidence; modifying the initial theory; and making suggestions. In addition, the structure of a realist review article was described and a checklist for evaluation of a realist review study was introduced.
Conclusion: The realist review is a suitable method for reviewing the complex health system interventions, explaining how an intervention relates to the results obtained. A realist review explains how, under what conditions and for whom a health and therapeutic intervention works.
