Systematic reviews are an integral component of evidence-based healthcare, but they can be hard to define. According to the Cochrane Library, a systematic review “is a high-level overview of primary research on a particular research question that tries to identify, select, synthesize and appraise all high quality research evidence relevant to that question in order to answer it.” (http://community-archive.cochrane.org/about-us/evidence-based-health-care) Like all quality research studies, the protocol used to conduct a systematic review must be spelled out in advance to minimize bias and to ensure that the review can be replicated by another group. Because of the rigor involved, systematic reviews can take several months to complete and usually involve two or more researchers. When done correctly, however, they can provide very reliable evidence for health care providers.
A quick search of PubMed shows that approximately 223 healthcare related systematic reviews have been completed here at the University of Vermont and more are ongoing. In an effort to support these projects, Dana Medical Library offered a series of three systematic review workshops this spring:
- Introduction to Systematic Reviews – led by Donna O’Malley and Gary Atwood, provided an overview of the elements that make up a systematic review and some of the issues that researchers encounter.
- Searching for Systematic Reviews – led by Donna O’Malley, showed researchers how to find existing systematic reviews for review.
- Going Gray: How to Find Gray Literature – led by Nancy Bianchi and Gary Atwood, outlined the role that gray literature plays in the systematic review process and reviewed potential sources that researchers can search.
The workshops were attended by faculty members, researchers, and students – many of whom are either at the initial stages of their own systematic review or anticipating one in the not too distant future.
Given the positive reaction to this first round of systematic review workshops, the Reference Librarians at Dana hope to offer them again in the future. Of course, researchers can also contact their liaison for help with their own research in the meantime.
