Objectives:
Urologists can benefit from a standardized system for guideline development and presentation. This article introduces the GRADE system and explains how it may be useful for Urologic physicians, in their practice and in their healthcare systems.
Methods:
The GRADE system is reviewed. Specific aspects of how GRADE rates the quality of the evidence and the strength of recommendations are explored.
Results:
GRADE can provide explicit and structured guidance, which separates the quality of evidence from the strength of recommendations. This information can be used by consumers of guidelines, including patients, physicians, and policy makers.
Conclusions:
Urologists can benefit from a more transparent and rigorous framework when formulating recommendations. GRADE is an emergent proposal with broader implications for healthcare policy as well.
