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.

- 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.

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.

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).

- 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.
