Systematic Reviews

A systematic review is a comprehensive literature search that tries to answer a focused research question using existing research as evidence.

Librarian Collaboration

The U.S. Institute of Medicine, in their publication, “Finding what works in health care: Standards for systematic reviews,” recommends that the systematic review author team be “multidisciplinary, with…librarians or information specialists trained in searching bibliographic databases” in addition to subject matter experts, statisticians, and methodologists (Institute of Medicine, 2011). It’s always good to have a librarian on your side! A 2015 article by Rethlefsen, et al., found that systematic reviews “with librarian or information specialist co-authors are correlated with significantly higher quality reported search strategies

Systematic Reviews follow established guidelines and best practices, and including a librarian on your team goal with the goal to work with you to produce a high-quality review. Most librarians offer two tiers of collaboration: Tier One (basic support) and Tier Two (research partner). Roles and expectations of librarians and research teams based on the tier of collaboration. 

Tier One: Librarian as an Advisor

  • Consultation to determine the feasibility of a systematic review vs other review types.
  • Provide guidance on best practices, protocols, or guidelines, e.g. PRISMA.
  • Recommend appropriate databases and advise on initial search strategies. 
  • Provide advice on Covidence review management software.

Tier 2: Librarian as Research Partner

In Tier Two Collaboration

Librarian Responsibilities

 

Research Team Responsibilities

  • Consult with research team to determine the feasibility of a systematic review vs other review types.
  • Decide on type of review, based on timeline and scope of project.  
  • Be an active member of the research team.
  • Decide on roles (two independent screeners, one tie-breaker, statistician) and responsibilities of team members. 
  • Provide advice on best practices and standards for reporting (e.g., PRISMA,  Cochrane, etc ). 
  • Adhere to best practices and standards for reporting (e.g., PRISMA, Cochrane, etc ).
  • Provide advice on protocol registration (PROSPERO).
  • Register systematic review protocol in PROSPERO.
  • Identify appropriate databases, develop search strategies, perform searches, and document search details. A second librarian will peer review search strategies to ensure the highest quality.
  • Provide the librarian with ample time to complete the searches after protocol is registered in PROSPERO.
  • Import references and train research team on Rayyan/ Covidence review management software.
  • Begin title/abstract screening as soon as librarian imports references into Rayyan/Covidence review management software.
  • Assist with selection of quality assessment (risk of bias) tools and development of customized quality assessment and data extraction forms in Rayyan/Covidence.
  • Perform quality assessment (risk of bias) of included studies, and data extraction.
  • Write the search methods section of the manuscript and provide reproducible search strategies for the appendix.
  • Include librarian as co-author, and send manuscript draft to librarian for review prior to submission. Include search strategies in the publications's appendix.

Before You Meet with Your Librarian

Before Meeting with the Librarian Do the Following:

Spend some time formulating your topic.

Many systematic review topics fit into the PICO framework; that is, Patient/Problem/Population, Intervention, Comparator/Control, and Outcomes. However, if your topic doesn’t quite fit that framework, that’s okay too. There are other topic development frameworks for building a viable systematic review query, like those outlined in the JBI Evidence Synthesis Manual. The more you are able to describe your topic, the better off you’ll be from the start. If you’re struggling, a librarian may be able to guide you in formulating an effective research topic.

Identify key articles.

You don’t have to do a significant amount of searching, but take a look around in a platform like PubMed, from the U.S. National Library of Medicine, and see if you are able to locate a couple of important articles on your topic. Your librarian will find them very helpful for creating an effective and comprehensive search and understanding what you want to find.

Have a draft of the protocol.

Even if you haven’t completed it yet, the protocol is helpful for your librarian to understand your topic a little better. It’s also critical to outline your inclusion and exclusion criteria from the start to minimize bias, but also to inform the search process. Don’t forget that there’s a protocol extension, the PRISMA-P, that you can use to aid in compiling a proper protocol. 

Make sure you’ve planned the timeline appropriately.

Did you know that the average systematic review takes 67.3 weeks (Borah, et al., 2018)? Tools like Covidence can help reduce the time as a collaboration tool, but because of the effort involved, it’s critical to plan ahead. Your librarian will be working on other projects during the same time that they’re working on yours and will need time to create, test, translate, and run your searches. If you plan ahead and bring your librarian in from the beginning, you’ll be able to tackle each step of the process in a timely manner.

Invite librarian co-authorship.

The International Committee of Journal Editors makes a recommendation of including as a co-author anyone who has “made substantial contributions to the conception or design of the work” and participated in the drafting and revision of the manuscript. In addition to consulting on the search, many librarians are prepared to assist you with the search methods section and elements of the PRISMA Flow Diagram.

 

During and after your consultation, the librarian will take an initial look at the literature to make sure that no recent systematic reviews have been published about your topic. They will also use your identified key articles to create a robust literature search. They’ll probably ask you some questions, such as: How do you plan to perform the screening? What citation management program do you prefer? After the searches are translated and completed, the librarian may deduplicate the results and send you the file of results so that you can get started on title/abstract screening.

Librarians are an invaluable member of a systematic review team, making significant contributions to a robust, high-quality, reproducible search, and consulting on citation management and the search methods. If you’re ready to do a systematic review, make friends with your librarian.
