Resource Profile: CQFM Computable Measure

The CQFM Computable Measure Profile describes minimum expectations for a computable electronic Quality Measure (QM), including the use of a computable library. For more information on the usage of this profile, refer to the Profiles and Packaging pages in this implementation guide.

Usage:

• Derived from this Resource Profile: CQFM Cohort Measure, CQFM Composite Measure, CQFM Continuous Variable Measure, CQFM Proportion Measure and CQFM Ratio Measure
• Examples for this Resource Profile: BCSComponent, CCSComponent, EXM108, EXM124... Show 11 more, EXM125, EXM130, EXM146, EXM55, MeasureEXM, EXMRatioMeasure, HBPComponent, MultiRateExample, PVSComponent, TSCComponent and Terminology_FHIR
