Are you currently working on a systematic review or research project and need assistance with search strategies and literature reviews? Himmelfarb Reference Librarians are skilled researchers who are trained to assist you with your review. A recent JAMA article extolled the benefits of using a medical librarian to improve the quality of a systematic review of the medical literature.
If you are considering a systematic review project, you should first consider its purpose. If you are investigating a well defined problem for which there exists several large clinical trials that follow quantitative research methods you will want to write an analytical review to summarise the results of trials and provide cumulative evidence about the efficacy of one specific intervention/treatment/dose. If you are investigating a less well understood problem for which there are few trials and/or you are reviewing observational data/qualitative research you will want to write a narrative review.
Having decided what type of literature review you wish to carry out, the next decision to think about is what is best way to present the information to your audience.
For a small audience such as journal club, grand rounds, or a conference proceedings, an analytical review can be summarised in a short review format such as: Cairns, J. (2012). ACP Journal Club. Review: Dabigatran increases MI and reduces mortality compared with warfarin, enoxaparin, or placebo. Annals Of Internal Medicine, 156(12), JC6-JC11. doi:10.7326/0003-4819-156-12-201206190-02011.
Alternatively you may wish to present the results of your literature review as a poster presentation such as: Abualenain, J., Alabdrabalnabi, T., Rasooly, I., Pines, J., Levett, P. (2013). The Impact of Interventions to Reduce Length of Stay in the Emergency Department: A Systematic Review. Poster presented by Dr. Abualenain at the Society for Academic Emergency Medicine (SAEM) 2013 Annual Meeting in Atlanta, Georgia, May 14-18, 2013.
Or publish your literature review in a journal article such as: Meier, E. R., Fasano, R. M., & Levett, P. R. (2017). A systematic review of the literature for severity predictors in children with sickle cell anemia. Blood Cells, Molecules & Diseases, doi:10.1016/j.bcmd.2017.01.014
When writing up the results of your systematic review for publication in a journal article for a wider professional audience you will need to include more detail about the methods you followed and the decisions you made on what studies to include/exclude from your review of the medical literature. For a narrative review guidelines on how to write up for publication are on the next tab of this research guide titled Types of literature review & methods. The rest of this research guide will focus on how to write up for publication an analytical review following the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses).
The PRISMA guidelines consist of a 27-item checklist and a four phase flow diagram. PRISMA is an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses.
The PRISMA guidelines were introduced in the journal article Liberati, A,, Altman, D,, Moher, D, et al. (2009). The PRISMA statement for reporting systematic reviews and meta-analyses of studies that evaluate health care interventions: explanation and elaboration. Plos Medicine, 6(7):e1000100. doi:10.1371/journal.pmed.1000100
It's a good idea to look at some examples of other review articles that cite this paper to see how the authors reported their systematic review following the PRISMA checklist. Here is a search in the PubMed database for some example reviews that have followed the PRISMA format.
The PRISMA Group have developed several extensions to the original PRISMA reporting standard for different types or aspects of systematic reviews, they include the following:
Here is a summary of what support Himmelfarb Librarians can offer to help with the literature search for your systematic review.
The Institute of Medicine's (2011) Standard (3.1.1) for Systematic Reviews suggests the review team "work with a librarian or other information specialist trained in performing systematic reviews to plan the search strategy." This guide outlines the role of the librarian in concordance with certain items in the Methods and Results sections of the PRISMA checklist:
