Prevention & Community Health: Systematic Review

Research Guide for the SPHHS Department of Prevention and Community Health

Step #1 Defining Your Research Question

A main characteristics of a systematic review is a clearly stated set of objectives with pre-defined eligibility criteria for studies. 

Help with clearly defining your research question, consider using PICO to help you frame your question in a complete format.

  • Patient or problem
  • Intervention
  • Comparison
  • Outcome

TIP: Check to see if there is a systematic review already published on your topic! 

Step #2: Create a Protocol for Search Criteria

Before you begin your search it is important to establish your eligibility criteria. A systematic search that attempts to identify all studies that would meet the eligibility criteria.  Include the following:

  • What is your inclusion criteria?
  • What is your exclusion criteria?

TIP: Your PICO statement should help drive what the inclusion/exclusion criteria
EXAMPLE: population characteristics (gender, age, disease...); study type (see Study Type 101 tutorial); date (specific date range if applicable; language (i.e English only); intervention (i.e. participants who completed smoking intervention program).

What is a Systematic Review?


“A systematic review is a review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research, and to collect and analyze data from the studies that are included in the review.”

Registered Protocol: PROSPERO

Once you have created  your "protocol" good practice is to register it with PROSPERO, an International Prospective Register of Systematic Reviews.

Benefits:

  • Registration is free!
  • You can search for systematic review protocols on your topic. (Very helpful to view other search strategies and inclusion/exclusion criteria)
  • Registering your protocol may help you publish your systematic review 

Step #3 Search Strategy

Searching for the literature on your topic begin by developing a search strategy with combination keywords and MeSH terms.  Consider the following databases (subject databases will depend heavily on your research topic)
