Systematic Reviews: Support Overview

Librarian Support

Interested in systematic reviews? A librarian can answer your questions via email or meet with you for one hour to offer guidance on the process, standards and best practices.


We can discuss the following during the hour: What you can expect to do before we meet:
  • Advice on:

    • Identifying appropriate review methodology and standards

    • Formulating a research question, defining inclusion/exclusion criteria, and registering a review protocol

    • Advise on developing systematic review searches, including the use of index terms in appropriate databases 

    • Assist with building an initial PubMed search

    • Explain or demo different databases and search interfaces 

    • Screening software and methodology for article screening, critical appraisal, and data extraction   

  • Recommendations about databases, grey literature resources, and citation management software 

  • Identification of relevant databases, potential journals, and suggested edits for existing search strategies 

  • Identify your team - typically 3-5 people, including the PI, context expert, 2 reviewers, and an operations manager.

  • Review your team's time commitment - typically 12-24 months

  • Provide information on review questions, purposes, background/significance. Provide citations and/or links for up to 3 relevant articles.

  • Review the types of reviews (i.e. literature, scoping) explained below.

Is a Systematic Review for Me?

Systematic review - A systematic review synthesizes data from articles into a summary review which has the potential to make conclusions more certain. Systematic reviews are considered the highest level of evidence in evidence-based medicine (EBM) evidence pyramidAn overview of the systematic review process includes:

  • Time Commitment: Typically 12–24 months from start to finish (may take longer)
  • Team Requirement: Typically 3-5 people at minimum. You will need at least a primary reviewer and a secondary reviewer. Other roles to consider include a subject expert, methodologist/statistician, operations manager, and medical librarian.
  • Topic: A significant question is being asked and answered. The topic is not the subject of a recent review and is not being worked on currently by others.

If this doesn't meet your needs, see "A typology of reviews: an analysis of 14 review types and associated methodologies".
