Systematic Review Resources

What Is a Systematic Review?

"A review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research, and to collect and analyse data from the studies that are included in the review. Statistical methods (meta-analysis) may or may not be used to analyse and summarise the results of the included studies." - from the Cochrane Handbook

Where Do I Find Systematic Reviews?

  • The Campbell Collaboration is an international research network that produces systematic reviews of the effects of social interventions focusing on education, crime and justice, and social welfare.
  • The Centre for Reviews and Dissemination (CRD) databases are updated daily and provide decision-makers with access to quality assessed systematic reviews, economic evaluations, summaries of health technology assessments, summaries of all Cochrane reviews and protocols, and summaries of Campbell reviews.
  • The Cochrane Database of Systematic Reviews (CDSR) includes the full text of regularly updated systematic reviews of the effects of healthcare prepared by The Cochrane Collaboration.
  • The Database of Abstracts of Reviews of Effects (DARE) covers a broad range of health related interventions and complements the CDSR by quality-assessing and summarizing reviews that have not yet been carried out by the Cochrane Collaboration. Each abstract includes a summary of the review together with a critical commentary about the overall quality.
  • Both PubMed and PubMed Clinical Queries can be used to locate systematic reviews. The Clinical Queries tool retrieves citations identified as systematic reviews, meta-analyses, reviews of clinical trials, evidence-based medicine, consensus development conferences, guidelines, and citations to articles from journals specializing in review studies of value to clinicians.

NOTE: Linking to the Cochrane Databases and PubMed through the Health Sciences Library ensures that you have access to the full text of systematic reviews and articles when available.
