Rating the Strength of Evidence and Recommendations for Disability
and Rehabilitation Research

April 14, 2010 (2 pm CDT / 3 pm EDT)

About the Webcast

Rating the quality of research evidence and strength of recommendations for evidence-based clinical guidelines/practice is an important issue in the field. The webcast will provide an overview of the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system for rating evidence and the strength of recommendations, and how to use its tools. A next step would be to see if there is a "fit" for GRADE within the disability and rehabilitation arena, at the pre-NARRTC Conference workshop, scheduled for May 2, 2010.

The GRADE Working Group "has developed a common, sensible, and transparent approach to grading quality of evidence and strength of recommendations." Recommendations to administer, or not administer, an intervention, should be based on the tradeoffs between benefits on the one hand, and risks, burden and, potentially, costs on the other. GRADE attempts to serve as a single system that avoids shortcomings seen in numerous complex systems and minimizes bias. Nearly 40 national and international organizations, including AHRQ, WHO, and the Cochrane Collaboration have endorsed the GRADE approach since it began in 2000. ›› Learn more about GRADE.
