MED 264: Systematic Reviews: Guides, Standards, Organizations

a resource for finding data sources and standards to support systematic searches of the biomedical literature

Guides

Cochrane Handbook
http://www.cochrane-handbook.org
The Cochrane Handbook has become the de facto standard for planning and carrying out a systematic review. Chapter 6, Searching for Studies, is most helpful in planning your reivew.

AHRQ Methods Guide for Effectiveness and Comparative Effectiveness Reviews
http://www.effectivehealthcare.ahrq.gov/index.cfm/search-for-guides-reviews-and-reports/?pageaction=displayproduct&mp=1&productID=318
Very good chapters on conducting a review, most of which were published as articles in the Journal of Clincal Epidemiology. For searching see especially Finding Evidence for Comparing Medical Interventions and Selecting Observational Studies for Comparing Medical Interventions.

Standards

You will improve the quality of your review by adhering to the standards below. Using the approriate standard assures editors and reviewers that you have consciencously carried out your reveiw.

Institutes of Medicine Standards for Systematic Reviews
http://iom.edu/Reports/2011/Finding-What-Works-in-Health-Care-Standards-for-Systematic-Reviews.aspx 
The IOM standards promote objective, transparent, and scientifically valid systematic reviews. They 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.

The PRISMA Statement
http://www.prisma-statement.org/
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses is an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses. A 27-item checklist,  PRISMA  focuses on randomized trials but can also be used as a basis for reporting systematic reviews of other types of research, particularly evaluations of interventions. PRISMA may also be useful for critical appraisal of published systematic reviews, although it is not a quality assessment instrument to gauge the quality of a systematic review.

MOOSE Guidelines
http://www.consort-statement.org/mod_product/uploads/MOOSE%20Statement%202000.pdf

Meta-analysis of Observational Studies in Epidemiology checklist contains specifications for reporting of meta-analyses of observational studies in epidemiology. Editors will expect you to follow and cite this checklist.  It refers to the Newcastle-Ottawa Scale for assessing the quality of non-randomized studies, a method of rating each observational study in your meta-analysis.
