Systematic Review Process: Planning Your Search

This guide will assist teammates and researchers at Advocate Health - Midwest who are seeking information on and instructions for conducting systematic reviews.

Your Search Plan

Search Plan

Your search plan will be a brief summary of the topic of the study, a summary of inclusion and exclusion criteria, a list of the appropriate publications, sources and methods that you will use for identifying materials and a list of concepts related to your topic. Your search strategy will put into operation the decisions you have made in your search plan.

PICO

Construct your search strategy using PICO or another appropriate framework such as SPIDER or ECLIPSE to ensure that the research question can be translated into search concepts. For more information on these frameworks, view our Effective Literature Searching guide

It may be useful to work with a librarian who has experience in a range of bibliographic databases to plan your search strategy. The librarian may, for instance, conduct a preliminary search of PubMed using their “clinical queries” to find recent systematic reviews on your research question.

You should plan to conduct your search in multiple databases. You will also modify your search strategy through trial and error since this is an iterative process.

Remember, Advocate Aurora librarians are available to suggest databases, help with search strategies and conduct searches for Advocate Health - Midwest team members.

Protocols For Your Project

It is recommended that you create a protocol for your systematic review project in order to:

  • minimize the risk of bias
  • promote transparency of your methods
  • avoid duplication of existing research

The protocol includes inclusion and exclusion criteria. Inclusion criteria is everything that a study must have in order to be included in your review. Exclusion criteria are the factors that would make a study ineligible to be included in your review.

These criteria may include dates, how a study was designed, population and outcomes. The protocol will also include eligibility, search strategy and how you'll assess the studies.

Note that to prevent bias you will need to include studies in other languages. Include in your protocol how you will find and translate these studies.

You should provide detailed documentation of your search strategy to ensure that it is reproducible and reported correctly. Document in detail where you are searching and what you are searching for.

Once you have developed a protocol, you should register it. Registering your protocol will let others know what you're researching, so they don't duplicate your work. Registering a protocol also makes your project more appealing to publishers because you have taken the time to avoid bias and duplication.

Sample organizations for registering protocols include:

  • PROSPERO
    An international database of prospectively registered systematic reviews in health and social care, welfare, public health, education, crime, justice, and international development, where there is a health-related outcome. PROSPERO accepts registrations for systematic reviews, rapid reviews and umbrella reviews but does not accept scoping reviews or literature scans.
     
  • The Cochrane Library
    A database that contain different types of high-quality, independent evidence to inform healthcare decision-making. It is mandatory to register and publish your protocol when conducting a Cochrane review. To register a review, please refer to proposing and registering a new Cochrane review.
     
  • Campbell Collaboration
    An international social science research network that produces high quality, open and policy-relevant evidence syntheses, plain language summaries and policy briefs. They accept proposal for new reviews, evidence and gap maps (EGMs), and methods research papers for publication in Campbell Systematic Reviews. Please consult the Campbell Collaboration for details on submitting proposals for systematic reviews.
     
  • Joanna Briggs Institute (JBI)
    An international research organization based in the Faculty of Health and Medical Sciences at the University of Adelaide, South Australia. JBI works with universities and hospitals from across the globe through the JBI Collaboration (JBIC), which is the largest global collaboration to integrate evidence-based healthcare within a theory informed model that brings together academic entities with hospitals and health systems. To register for new JBI Systematic Review, at least one of the authors must be from JBI affiliated entities
