Cochrane Rapid Reviews Methods Group offers evidence-informed guidance to conduct rapid reviews

Open access

Abstract

OBJECTIVES: To develop methods guidance to support the conduct of rapid reviews (RRs) produced within Cochrane and beyond, in response to requests for timely evidence syntheses for decision-making purposes including urgent health issues of high priority. STUDY DESIGN AND SETTING: Interim recommendations were informed by a scoping review of the underlying evidence, primary methods studies conducted, and a survey sent to 119 representatives from 20 Cochrane entities, who were asked to rate and rank RR methods across stages of review conduct. Discussions among those with expertise in RR methods further informed the list of recommendations with accompanying rationales provided. RESULTS: Based on survey results from 63 respondents (53% response rate), 26 RR methods recommendations are presented for which there was a high or moderate level of agreement or scored highest in the absence of such agreement. Where possible, how recommendations align with Cochrane methods guidance for systematic reviews is highlighted. CONCLUSION: The Cochrane Rapid Reviews Methods Group offers new, interim guidance to support the conduct of RRs. Because best practice is limited by the lack of currently available evidence for some RR methods shortcuts taken, this guidance will need to be updated as additional abbreviated methods are evaluated.

TL;DR

The Cochrane Rapid Reviews Methods Group presents interim, evidence-informed guidance with 26 recommendations for conducting rapid reviews, based on scoping reviews, primary methods studies, and a Cochrane stakeholder survey. It defines rapid reviews as accelerated knowledge synthesis and emphasizes stakeholder involvement, flexibility, and transparency.

Key findings

  • The survey had a 53% response rate (n = 63; completed 46%, n = 53), with respondents from 19 of 20 Cochrane entities; 62% (n = 39) had previously participated in a rapid review, and only 1 of 59 respondents indicated Cochrane should not undertake rapid reviews.
  • The label “Cochrane RR” was endorsed by 43/57 respondents (75%), and 26 rapid review methods recommendations were included where there was high or moderate agreement or where an item ranked first.
  • Agreement thresholds were high ≥70%, moderate ≥50–69%, and low <50%; if only low-level agreement was reached, the most endorsed response was still recommended so each stage had a recommendation.
  • The recommended definition is: “A rapid review is a form of knowledge synthesis that accelerates the process of conducting a traditional systematic review through streamlining or omitting various methods to produce evidence for stakeholders in a resource-efficient manner.”

Methods

  • Guidance was informed by two scoping reviews (one of 216 rapid reviews and 90 methods articles; one identifying 14 empirical studies evaluating rapid review methods), two primary methods studies (English-language restriction; single- vs dual-reviewer screening via Cochrane Crowd), and a survey.
  • The survey was sent in September 2019 to 119 individuals from 20 Cochrane entities; results were analyzed with descriptive statistics, and recommendations were mapped to Cochrane MECIR guidance where possible.
  • Final recommendations were agreed through discussion among RRMG convenors; the authors state they did not follow a formal recommendation process but used a deliberate and systematic approach.

Limitations

  • Stated: the survey response rate was somewhat lower than typical Internet surveys (58%); not all rapid review stages had corresponding evidence; best practice is limited by lack of currently available evidence for some shortcuts; and the interim guidance will need updating as abbreviated methods are evaluated.
  • Stated: the guidance was developed within Cochrane and focused on rapid reviews of interventions; the authors note future adaptation is needed for other review types (e.g., diagnostic test accuracy or screening), and some recommendations may not apply across all rapid reviews.
  • Evident: no formal ethics approval was sought because the survey was internal, and no formal recommendation process was used; some recommendations therefore rest on expert/survey agreement where empirical evidence was absent.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
