The Evolution of Coronary Revascularization Appropriateness Use Criteria: From Mandatory to Forgotten.

The appropriateness use criteria (AUC) for coronary revascularization have been formulated through the joint efforts of several professional societies. The goals of AUC were to aid in physician decision making and to objectively define the need and context for revascularization. These criteria, developed using a standardized approach, were widely promoted and adopted in many practices. Rigorous use in daily practice and public reporting of adherence to these criteria has exposed some of their deficiencies. Revisions to the original version were made to accommodate public and physician sentiments. Not surprisingly, the recent percutaneous coronary intervention performance measures developed by the same professional societies that have proposed AUC, have suggested that AUC should be used for internal quality improvement only at this time. Therefore, the present role and future application of AUC to cardiology practice is uncertain. The goals of this review are to describe methodology and development of the coronary revascularization AUC, to focus on the strengths and limitations of AUC, and to identify challenges related to application of these criteria in daily practice.
