An example of harmo- nization within the measure set is the postprocedural optimal medical therapy composite measure in the present document, which is aligned with the similar National Quality Forum endorsed ACCF facility-level measure.

General Discussion 4.1. Process Measures Process measures have several advantages. They are more readily under the control of clinicians than are structural or outcome measures and also are actionable targets for quality improvement.
