Now Available: Quality Data Model (QDM) v5.3

June 16, 2017 - 11:27am

The Centers for Medicare & Medicaid Services has released the latest changes to the Quality Data Model (QDM) specification, version 5.3, for use with Clinical Quality Language (CQL). Support for these features and modifications will be implemented in the production version of the Measure Authoring Tool (MAT) released in Fall 2017 (version 5.4).

QDM v5.3 represents a significant change from prior production versions as it no longer contains any logic expression. Previously published versions of the QDM (through version 4.3) included the data model and logic required to compare one data element to another. Beginning with the QDM v5.0 Draft for use with CQL testing, the QDM includes only the data model, whereas this and future versions require the use of CQL as a separate method for expressing logic. QDM v5.02 and v5.03 included minor changes for use with CQL testing. Version 5.3 is the production version for CQL-based eCQMs.

QDM will continue to evolve based on stakeholder input and feedback from the QDM User Group.
