Background: Rapid systematic reviews (RRs) are a useful tool to provide healthcare decision-makers with the most up-to-date scientific evidence. Yet there remains much uncertainty about the most effective and efficient methods for carrying out RRs. In fact, there is even uncertainty about which are the main methodological concerns for RRs.
Objectives: To elicit a consensus from RR researchers on what they consider the most important methodological questions when conducting RRs in time-efficient ways.
Methods: People with experience in conducting and using evidence syntheses (researchers, knowledge users, policymakers, and healthcare providers) were invited to participate in an eDelphi study. A core group of experts generated an initial list of questions based on the available literature. Participants were then asked to rate and rank the importance of the methodological questions. Three survey rounds were performed to achieve a consensus. Items deemed of low importance were removed at each round. Items rated to be of high importance by ≥75% of participants were included in the final list.
Results: Each survey round elicited feedback from 52 to 70 experts. Of participants, 78% self-identified as researchers, 13% as healthcare practitioners, and 9% as policymakers. More than 30% of participants reported 15+ years of experience in evidence synthesis. The first survey round started with 29 items, and new items were suggested. In the second round, 26 items remained on the list. In the final round, only 7 Items were believed to be of high importance by ≥75% of participants. Three items concerned the search strategy, two focused on study selection, and two focused on quality/bias assessment. Conclusion: Seven items were consistently identified as highly important methodological concerns related to RRs. A consensus meeting will be held to discuss additional items and to generate a summary document containing the final priority list. The results will be used to inform further research in this area, contributing to the development of reliable and rigorous RRs. Patient, public or healthcare consumer involvement: Given the emphasis on the methodological aspects of RRs, patients were not included. The eDelphi does include interested parties, such as guideline and policy developers and end-users.
