Systematic Review Program: Getting Started

Thinking of doing a systematic review?

What is a systematic review?

"A scientific investigation that focuses on a specific question and that uses explicit, planned scientific methods to identify, select, assess, and summarize the findings of similar but separate studies. It may or may not include a quantitative synthesis of the results from separate studies (meta-analysis) depending on the available data." IOM p 1.

What do systematic reviews accomplish?

"Well-conducted systematic reviews systematically identify, select, assess, and synthesize the relevant body of research, and will help make clear what is known and not known about the potential benefits and harms of alternative drugs, devices, and other healthcare services. Thus, systematic reviews of comparative effectiveness research (CER) can be essential for clinicians who strive to integrate research findings into their daily practices, for patients to make well-informed choices about their own care, for professional medical societies and other organizations that develop clinical practice guidelines (CPGs), and for payers and policy makers.SRs can also inform medical coverage decisions and be used to set agendas and funding for primary research by highlighting gaps in evidence."  IOM p. 17.

Report at a Glance: Standards for Systematic Reviews. (brief list)

"These standards address the entire systematic review process, from locating, screening, and selecting studies for the review, to synthesizing the findings (including meta-analysis) and assessing the overall quality of the body of evidence, to producing the final review report.

These standards are for systematic reviews of comparative effectiveness research of therapeutic medical or surgical interventions."

A systematic review primer

" Targeted to beginners....... this primer (1) highlights the differences between review types; (2) outlines the major steps in performing a systematic review; and (3) offers a set of resources to help authors perform and report valid and actionable systematic reviews."

How long does it take to complete a systematic review?

Planning and conducting a systematic review is a time intensive research project.  Time to completion will vary depending on the scope of the review and the size and availability of the review team.  A well-designed systematic review may take a year or more to complete.

The Cochrane Handbook for Systematic Reviews of Interventions  provides the following  table showing estimated time for each task.
