Abstract: |
(from the chapter) Systematic reviews have been integral to the evidence-informed practice movement as a means to keep up with the ever-increasing amount of literature on a given topic. However, decision makers are increasingly faced with an abundance of such reviews. Recently, the average number of systematic reviews published each day was estimated at 11. This equates to 330 each month or 3,960 per year. Umbrella reviews (or overviews) of reviews are a logical and appropriate next step, allowing linkages to be formed from the findings of separate reviews. An umbrella review does not duplicate searches, assessment of eligibility, assessment of risk of bias or meta-analyses from the included reviews, but rather provides an overall picture for a particular phenomenon. This is a more useful and inclusive method of informing guidelines and clinical practice. This chapter discusses systematic review. A systematic review is a descriptive research method in which the subjects or informants in the study are published or unpublished primary studies, rather than human subjects. Systematic reviews are an accepted form of research, the findings of which are used by practitioners to make point-of-care decisions based on the best available evidence for a focused clinical question.
