Sizing Up Systematic Reviews: Not All Syntheses Are Created Equal
Senior Program Officer
Patient-Centered Outcomes Research Institute (PCORI)
About the Webinar
Systematic evidence reviews have become known as the “gold standard” for health care decision-makers in search of the most reliable and comprehensive information about a given clinical or public health topic. By taking a rigorous and transparent approach to identifying, assessing, and synthesizing a group of eligible studies on a specific clinical question, the reviews can make clear what is known and what the important remaining evidence gaps still to be answered are. As such, systematic reviews have become a cornerstone of trustworthy clinical practice guidelines.
The number of such reviews has increased exponentially in recent years, sometimes even exceeding the number of available trials in a given clinical topic area. With all of this activity, it is perhaps not surprising that sometimes even systematic reviews come to different conclusions on the same subject. So how do you know what to conclude? Which is “right”?
Using case examples as a guide, this talk demonstrates methods to critically assess the quality of published systematic reviews of clinical or public health interventions.
