  • Note: I do not have to be involved for a systematic review to be accomplished; however, Cochrane as well as many other agencies have indicated that by having an information professional (librarian) involved will increase the success and decrease the bias of the study.

Systemtic reviews in a nutshell

systematic reviews can use different studiesA systematic review (SR)...“seeks to systematically search for, appraise and synthesize research evidence, often adhering to guidelines on the conduct review.” - Cochrane Handbook

Systematic reviews are NOT literature reviews.

SRs use primary studies as data and so are secondary studies. The quality of the studies included and the level of rigor in the search, defines the quality of the SR. Traditionally, a SR was only of randomized control trials (RCTs). But you can gather and analyze a variety of study types. Meaning, out of all of the evidence out there, whether it’s RCTs, case studies, thesis... what is of quality and answers my specific question.

Important Characteristics of a SR:
Systematically search (rigorous methodology)
Study appraisal (quality evidence)
Synthesis (answer question)
Guidelines (standards, protocols, etc.)

A bit of history

SRs started gaining popularity in medicine in the 90s as a methodology to review all possible evidence at one time. SRs seek to answer a VERY specific question (such as a PICO) in order to eliminate bias and save time for your doctor to make a clinical decision. Or for policy makers to make a decision based on evidence, in a timely manner.

Basically, with the increase of literature, there was a need for a analyzing the studies that have been done so one did not have to read all 20 articles, but could rely on this one, review.
