Systematic Reviews: About systematic reviews

Who is this guide for?

This guide is for anyone conducting a systematic, scoping or systematised review. 

What is a systematic review?

A systematic review has a focused research question, it follows a set methodology that should be transparent, reproducible, and less biased than a narrative review. It will have a protocol and you will search multiple bibliographic databases (such as the Web of Science, MEDLINE, CINAHL, PsycInfo) as well as searching for grey literature (unpublished reports, guidelines, thesis, clinical trials).

Other review types?

There are many type of reviews, each will have their own methodology, see table 3 in this article by Sutton, A. et al. (2019) 'Meeting the review family: exploring review types and associated information retrieval requirements', Health Information & Libraries Journal, 36(3), pp. 202-222. Available at: https://doi.org/10.1111/hir.12276 and Temple University has a good guide https://guides.temple.edu/c.php?g=78618&p=9552831. There is also a useful tool called, Right Review that helps you decide what type of review would be most useful for you, see https://whatreviewisrightforyou.knowledgetranslation.net/

How can the library help?

For staff and postgraduate research students we offer online training sessions advertised via the Doctoral College and StaffBook, the session introduces the literature search process required for a systematic review and complements the course offered by SHTAC.

The library can help you:

  • decide on the bibliographic databases to include in your review, 
  • develop your search strategy, 
  • check your search strategies,
  • guide you to tools to assist with your review.
