Critical Appraisal: limiting quality appraisal to methodological appropriateness and quality.ĭue to these limitations, an REA may be more prone to bias than a SR.

Data Extraction: only extracting a limited amount of key data, such as year, population, sector, study desig, sample size, moderators/mediators, main findings, and effect sizes.

Inclusion: only including specific research designs (e.g.

Searching: consulting a limited number of databases, and excluding unpublished research.

Aspects of the search may be limited to produce a quicker result: In order to be ‘rapid’ an REA makes concessions in relation to the breadth, depth and comprehensiveness of the search. The main way in which these two types of summaries vary is in relation to the time and resources used to produce them and the scope and depth of the results produced. An REA applies the same methodology as a SR and both involve the following steps: Because of this the likelihood of bias is considerably smaller in a SR compared to traditional literature reviews.Ī Rapid Evidence Assessments (REAs) is another type of evidence summary that can inform practice. A SR is therefore transparent, verifiable and reproducible. A systematic approach is applied to selecting studies: the methodological quality of the studies in question is assessed by several researchers independently of each other on the basis of explicit criteria. These studies are then assessed to ascertain their internal validity. The aim of a systematic review (SR) is to identify all relevant studies on a specific topic as comprehensively as possible, and to select appropriate studies based on explicit criteria.

the review that presents the most valid and reliable scientific evidence, is the systematic review. What is a Rapid Evidence Assessment (REA)?
