Coproduction in evidence synthesis is increasingly recognized as essential for developing meaningful evidence for decision-making. However, little is known about when, how, and whom to involve, and no clear research agenda exists to guide which methodological aspects of coproduction should be prioritized. This study aimed to identify and prioritize research topics through a rigorous process.
This study employed a Delphi process based on James Lind Alliance (JLA) methodology for research priority setting and predefined in the study protocol (https://osf.io/q3r7u/files/j3bmd). The authors adapted methods from JLA in two ways.
First, rather than focusing on a specific health condition involving people with lived experience, they examined methodological research priorities in coproduction of evidence synthesis, a broader research area of interest to the general public. They defined five interest-holder groups relevant to evidence synthesis: patients/carers/public, researchers, coproduction experts, policymakers, and health professionals.
Second, they used a Delphi approach where participants rated predefined topics, which were used to analyse group and overall mean scores to identify priorities instead of creating individual priority lists for consensus discussion. We, however, maintained core JLA principles of equal participation across interest-holder groups and transparency in the process.
