Systematic Reviews

A guide to conducting systematic reviews at the University of the Sunshine Coast

Protocol overview

Once you have defined your question, you need to develop a systematic review protocol. The purpose of a protocol is to outline your systematic review process in a clear and transparent manner to reviewers and readers.

The content in a protocol includes:

  • Research questions and aims of the review.
  • Your PICO breakdown (or the relevant framework you are using).
  • Your eligibility criteria (inclusion and exclusion).
  • Where you will search (databases and grey literature).
  • How you will:
    • screen your records
    • extract and manage the data
    • assess bias
    • analyse data

Your eligibility criteria is what you plan to include and exclude from your review. It needs to:

  • match each of your PICO elements
  • be agreed upon by all reviewers before screening starts

The key areas for your criteria are:

Demographic factors

e.g. age, sex, ethnicity

Study design and duration

e.g. what types of studies do you need to answer your question?

Measure

e.g. are you looking at a particular type of measure?

Date range

e.g. only apply a date range if you are updating a previously published systematic review

PRISMA for systematic review protocol (PRISMA-P)

PRISMA-P is 'a guideline to help authors prepare protocols for planned systematic reviews and meta-analyses that provides them with a minimum set of items to be included in the protocol.' - PRISMA-P Statement, p. 2

Publisher requirements

While PRISMA-P is the preferred reporting items for systematic reviews and meta-analysis, there may be other specific requirements from your review body or publisher, for example:

  • breakdown of number identified through databases searches.
  • breakdown of number of records excluded through:
    • title screening
    • abstract screening
    • full-text screening

Registering your protocol

It is a good practice to register your protocol, as you do not want anyone else to do the exact same review you are doing.

Reviews with health-related outcomes (systematic, umbrella, rapid, but not scoping) can be registered on PROSPERO. Once you register, your review will:

  • be available open access through the PROSPERO database.
  • have a unique registration number. This number can be cited in publications and reports to provide the link between your planned and completed review. This is recommended by PRISMA (2009) and many publishers.

If you are working on a review for an organisation affiliated with JBI (Joanna Briggs Institute) - a 'JBI Collaboration Entity' -  you can register the title of your review on their website.

 

Publishing your protocol

You can publish your protocol in various journals. There are some examples below:

Protocols for Cochrane and Joanna Briggs Institute reviews are published on their websites:
