Quality Measurement and Reporting

Page standards status: Informative

Clinical Quality Language has been in use in the quality measurement domain for many years to provide computable representation of logic as part of quality measure specifications. Much of the guidance and patterns presented in this implementation guide are generalizations of patterns established for use in specifying quality measures in FHIR.

For more detailed information on this use case, see:

• QI Core: Quality improvement profiles, derived from US Core, adding additional information and in support of quality improvement use cases
• Quality Measures: Quality Measures implementation guide, describes how to use FHIR Clinical Reasoning and CQL to represent structured and computable quality measure specifications
• Data Exchange for Quality Measures: Data Exchange for Quality Measures, describes how to use quality measure specifications to exchange data-of-interest for quality measures, as well as calculate and report quality measures.

Measure specifications for use in the US Realm can make use of content from this implementation guide as these patterns and libraries are refined through implementation experience.
