Systematic Review

This document provides an overview of what a systematic review is in 3 paragraphs. It begins by stating that systematic reviews have replaced traditional narrative reviews as they bring a rigorous methodology to summarizing research evidence. The second paragraph outlines the key steps of a systematic review which include identifying all relevant published and unpublished evidence, assessing study quality, synthesizing findings, and interpreting results in an unbiased way. The third paragraph notes that while many high quality systematic reviews are available, not all published ones have been rigorously conducted so their findings may sometimes mislead without interrogation.

G Systematic reviews have increasingly replaced traditional narrative reviews and expert commentaries as a way of summarising research evidence. G Systematic reviews attempt to bring the same level of rigour to reviewing research evidence as should be used in producing that research evidence in the first place. G Systematic reviews should be based on a peer-reviewed protocol so that they can be replicated if necessary. G High quality systematic reviews seek to:

Identify all relevant published and unpublished evidence Select studies or reports for inclusion Assess the quality of each study or report Synthesise the findings from individual studies or reports in an unbiased way Interpret the findings and present a balanced and impartial summary of the findings with due consideration of any flaws in the evidence.

G Many high quality peer-reviewed systematic reviews are available in journals as well as from databases and other electronic sources. G Systematic reviews may examine quantitative or qualitative evidence; put simply, when the two or more types of evidence are examined within one review it is called a mixed-method systematic review. G Systematic reviewing techniques are in a period of rapid development. Many systematic reviews still look at clinical effectiveness, but methods now exist to enable reviewers to examine issues of appropriateness, feasibility and meaningfulness. G Not all published systematic reviews have been produced with meticulous care; therefore, the findings may sometimes mislead. Interrogating published reports by asking a series of questions can uncover deficiencies.
