Measure Selection Measure de nition a) The patient group to whom the measure applies (denominator) and the patient group for whom conformance is achieved (numerator) are clearly defined and clinically meaningful. Measure exceptions and exclusions b) Exceptions and exclusions are supported by evidence. Reliability c) The measure is reproducible across organizations and delivery settings. Face validity d) The measure appears to assess what it is intended to. Content validity e) The measure captures most meaningful aspects of care. Construct validity f) The measure correlates well with other measures of the same aspect of care. 3. Measure Feasibility Reasonable effort and cost* a) The data required for the measure can be obtained with reasonable effort and cost. Reasonable time period b) The data required for the measure can be obtained within the period allowed for data collection. Actionable* a) Those held accountable can affect the care process or outcome. Unintended consequences avoided b) The likelihood of negative unintended consequences with the measure is low.

Prior research demonstrated that the indication for revascularization can be captured and evaluated for appropriateness, although high rates of incomplete data collection were noted (19). These criteria propose that emergency or urgent revascularization for patients with acute coronary syndromes is generally considered appropriate.
