A systematic review is a research method in which a team formulates a research question, searches, selects, and appraises the literature in order for researchers, practitioners, and policy-makers to make evidence based decisions.
The key characteristics of a systematic review are:
- a clearly stated set of objectives with an explicit, reproducible methodology;
- a systematic search that attempts to identify all studies that would meet the eligibility criteria;
- an assessment of the validity of the findings of the included studies, for example through the assessment of risk bias; and
- a systematic presentation, and synthesis, of the characteristics and findings of the included studies.
Systematic reviews are reproducible, transparent, and the methods used are documented. A systematic review answers specific questions which are fully described in the protocol. Bias is minimized by having at least two people on the team do each step. A systematic review may take a year or more to complete.
Librarians are expert searchers who can support and guide investigators throughout the systematic review process.
