Reviews and Evidence Syntheses: Umbrella Review

Definition

Umbrella Reviews are high-level syntheses and critical summaries of research evidence as presented in systematic reviews.  They may also be called 'overviews of reviews',  'reviews of reviews', or 'meta-reviews' (not to be confused with meta analyses).

Goal or Purpose Or Key Features

The goal of an umbrella review is to provide a user-friendly summary of the recommendations and conclusions published in systematic reviews or meta analyses on a topic.  They give clinicians, policy makers, and others the ability to quickly understand what multiple evidence syntheses have found and act on that information.

Key features include:

  • The only type of publication included is a previous systematic review of meta analysis rather than primary studies such as randomized controlled trials, etc.
  • Provide overviews of broad research questions (sometimes even broader than the individual systematic reviews included) by comparing systematic reviews that may iinclude
    • Different interventions for the same problem
    • Different methods for the same intervention
    • Different populations for the same intervention
  • Assessment the quality of the included systematic reviews to ensure that the best evidence is being aggregated
