When did Clinical Quality Language (CQL) replace the expression logic portion of the QDM?

QDM versions prior to v.5.3 included both the conceptual data model (the categories and their context of use) and the expression logic to state measure clauses. QDM versions since v.5.3 include only the conceptual data model. This change occurred with electronic clinical quality measures designed for the 2019 reporting/performance period when measure developers started using CQL to express logic. Download current versions of the QDM from the Electronic Clinical Quality Improvement (eCQI) Resource Center QDM About tab.
