A systematic review uses a structured and reproducible method to identify, assess and critically appraise all relevant studies in response to a specific research query. It can be either quantitative or qualitative, and will generally take a team of researchers many months to complete (Wilkinson, 2020).
The key characteristics of a systematic review are:
a clearly stated set of objectives with pre-defined eligibility criteria for studies;
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 of bias; and
a systematic presentation, and synthesis, of the characteristics and findings of the included studies (Higgins & Thomas, 2019).
A systematic review is a rigorous type of evidence synthesis. Systematic reviews require more time and manpower than traditional literature reviews. While this guide focuses on systematic reviews, readers should be aware of the other types of reviews (scoping reviews, narrative reviews, etc) that are viable forms of evidence synthesis.

Grant and Andrew Booth.
How can the UVic Libraries help?
The National Academy of Medicine, PRIMSA, and the Cochrane Collaboration all recommend consulting with a librarian when developing a systematic review. Librarians are specially trained in developing search strategies and methodologies for systematic reviews.
Librarians trained in evidence synthesis methods can provide support in many stages of the review process. For example, we can:
Contact UVic Libraries for a systematic review consultation. List your department in the request.
Please note that librarians can only advise on search strategies, documentation, and information resources, and they will not conduct searching on your behalf.

Yale University's Harvey Cushing/John Hay Whitney Medical Library Systematic Searches tutorial page
This series of tutorials cover the fundamental concepts and general procedure of searching the health science literature in a systematic manner. They will mainly focus on systematic searches required by a "systematic review". The goal of these tutorials is to ensure that your search is comprehensive, methodical, transparent and reproducible, so that your conclusions are as unbiased and closer to truth as possible.
