Systematic Reviews - Definition

  • A systematic review brings together all empirical evidence that fits specific eligibility criteria to answer a very direct research question. Key characteristics of a systematic review are: a clear and concise question, specific inclusion and exclusion criteria, a rigorous and systematic search of the literature, critical appraisal of included studies, mechanisms to manage the citations and data, analysis and interpretation of the results and a final report for publication.
  • Difference between Literature Reviews and Systematic Reviews

Guides and Manuals

  • Finding What Works in Health Care: Standards for Systematic Reviews (IOM)

    IOM's (2011) standards address the entire systematic review process, from locating, screening, and selecting studies for the review, to synthesizing the findings and assessing the overall quality of the body of evidence, to producing the final review report. Includes a link to the IOM Standards for Systematic Reviews.

  • Cochrane Collaboration Handbook

    The Cochrane Handbook for Systematic Reviews of Interventions is the official document that describes in detail the process of preparing and maintaining Cochrane systematic reviews on the effects of healthcare interventions. This is Version 5.1.0 of the Handbook; last edited March 20, 2011.

  • Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA Statement)

    The aim of the PRISMA Statement is to help authors improve the reporting of systematic reviews and meta-analyses. The focus of PRISMA is randomized trials, but it can also be used as a basis for reporting systematic reviews of other types of research, particularly evaluations of interventions.

  • Methods Guide for Effectiveness and Comparative Effectiveness Reviews (AHRQ)

    This guide was developed to improve the transparency, consistency, and scientific rigor of those working on Comparative Effectiveness Reviews.

    Guidelines for producing a Campbell Systematic Review. The Campbell Collaboration is an international research network that produces systematic reviews of the effects of social interventions.

  • Systematic Reviews: CRD’s Guidance for Undertaking Reviews in Health Care

    Provides practical guidance for undertaking evidence synthesis based on a thorough understanding of systematic review methodology. Presents core principles of systematic reviews and highlights issues that are specific to reviews of clinical tests, public health interventions, adverse effects, and economic evaluations. The final chapter discusses incorporation of qualitative research in or alongside effectiveness reviews.

  • Qualitative Research Guide

    Online resources to aid in conducting, finding, using, synthesizing, and teaching qualitative research in health sciences.

  • Systematic reviews are widely recognised as reliable sources of information about the effects of health and social care interventions. But as with individual research studies, they can be hard to find, may have flaws and can be difficult to interpret. Between 1994 and March 2015, CRD produced and maintained DARE, a database uniquely providing access to over 13,000 abstracts of quality assessed and critically appraised systematic reviews.

What does it take to do a Systematic Review?

  • Time - Average time for a review is 18 months. Cochrane Reviews take approximately 2 years.
  • Team - Cochrane Reviews require teams to complete a review. Most reviews include subject specialists as reviewers to screen abstracts, statisticians to help with data analysis, librarians to develop comprehensive search strategies and a project leader to coordinate.
  • Defined Question - Clear and concise research question is the key to a good systematic review. Use PICO framework to identify key concepts and determine inclusion and exclusion criteria.
    • P=patient, population or problem
    • I=intervention, prognostic factor or exposure
    • C=comparison or intervention
    • O=outcome you would like to measure or achieve
  • Written protocol - To outline the study methodology.
  • Registered protocol - Register your protocol with PROSPERO. Registration is free and open to anyone undertaking a systematic review. You are required to register a protocol with Cochrane.
  • Comprehensive Literature Search - Identify key databases, develop a search strategy, conduct a comprehensive and detailed search and keep documented evidence of citations.
  • Citation Management - Best to work with a citation management system.
  • Follow reporting guidelines - Use appropriate guidelines for review of your publication.

Appraisal and Analysis

  • Jadad Scale

    The Jadad scale, sometimes known as Jadad scoring or the Oxford quality scoring system, is a procedure to independently assess the methodological quality of a clinical trial. Jadad et al. published a three-point questionnaire that formed the basis for a Jadad score. Jadad, A.R.; Moore R.A., Carroll D., Jenkinson C., Reynolds D.J.M., Gavaghan D.J., McQuay H.J. (1996). "Assessing the quality of reports of randomized clinical trials: Is blinding necessary?". Controlled Clinical Trials 1996 17 (1): 1–12. PMID 8721797

  • The Newcastle-Ottawa Scale (NOS) for assessing the quality of nonrandomised studies in meta-analyses

    Nonrandomised studies, including case-control and cohort studies, can be challenging to implement and conduct. Assessment of the quality of such studies is essential for a proper understanding of nonrandomised studies. The Newcastle-Ottawa Scale (NOS) is an ongoing collaboration between the Universities of Newcastle, Australia and Ottawa, Canada. It was developed to assess the quality of nonrandomised studies with its design, content and ease of use directed to the task of incorporating the quality assessments in the interpretation of meta-analytic results.

  • Review Manager (RevMan) is the software used for preparing and maintaining Cochrane Reviews. You can use RevManfor protocols and full reviews. It is most useful when you have formulated the question for the review, and allows you to prepare the text, build the tables showing the characteristics of studies and the comparisons in the review, and add study data. It can perform meta-analyses and present the results graphically.
