To achieve this goal, the ACC/AHA Task Force on Performance Measures has outlined a set of mandatory sequential steps.1 The following sections outline how these steps were applied by the present writing committee. 2.1. Identifying Clinically Important Outcomes To guide the selection of measures for inclusion in the mea- sure set, the writing committee sought to identify structures, processes, and outcomes that are most meaningful to patients undergoing PCI, as recommended by recent guidelines and appropriate use criteria (AUC). A key aspect was to determine outcomes that are most relevant for patients. A complete list of the desirable outcomes identified by the writing committee and how they relate to the proposed process measures is included in the measure specifications that can be found at http://www.ama- assn.org/apps/listserv/x-check/qmeasure.cgi?submit=PCPI. 2.2. Dimensions of Care Given the multiple measurable domains of providing care, the writing committee identified and explicitly articulated the rel- evant dimensions of care that should be evaluated.As part of the methodology, each potential performance measure was catego- rized into its relevant dimension of care (Table 2). Classification into dimensions of care facilitated identification of areas in which evidence was lacking and prevented duplication of Table 2. 2013 ACC/AHA/SCAI/AMA-PCPI/NCQA Percutaneous Coronary Intervention Performance Measure Set: Dimensions of Care Measures Matrix* Measure Name Diagnostics Patient Education Treatment Self-Management Monitoring of Disease Status Comprehensive Documentation of Indications for PCI 2.
