This Component supports communication of a quality measure (aka an "eMeasure"). Clinical concepts (e.g. "atrial fibrillation", "coronary artery disease") and parameters (e.g. "numerator", "denominator") in an eMeasure are formally defined to support consistent and unambiguous interpretation. The eMeasure is standardized as a structured document, where one can capture the complete narrative of the measureand a formalized computable representation of statements.
