Now Available: Quality Data Model (QDM) v5.4 August 2018 Publication

August 29, 2018 - 12:57pm

The Centers for Medicare & Medicaid Services has published the Quality Data Model (QDM), v5.4. The standard has been updated to align with the emerging standard, Health Level Seven International (HL7info-icon) Fast Healthcare Interoperability Resources (FHIR) and add increased explicit capabilities. Support for these features and modifications will be implemented in the production version of the Measure Authoring Tool (MATinfo-icon) to be released in the fall of 2018 (MAT v5.6). Measures produced using this QDM v5.4 publication are anticipated for implementation in calendar year 2020, whereas QDM v5.3 is for calendar year 2019. 

Note that the referenced document fixes minor errata noted in the document initially published to the eCQI Resource Centerinfo-icon in June 2018 and contains these changes:

  • Updates to address errata: inadvertent inclusions in attribute table 22 (p. 51) – Laboratory Test, Order and Laboratory Test, Recommended removed from status attribute
  • Adds the attribute daysSupplied for Medication, Order; Medication, Dispensed; and Medication, Discharge
  • Adds the attribute prescriberIdentifier to Medication, Order and Medication, Dispensed
  • Adds the attribute dispenserIdentifier to Medication, Dispensed

Previously published versions of the QDM (through v4.3) included the data model and logic required to compare one data element to another. With the adoption of Clinical Quality Language (CQL)info-icon by CMS in the fall of 2017, the QDM includes only the data model. This and future versions of the QDM require the use of CQL as a separate method for expressing logic. QDM will continue to evolve based on stakeholder input and feedback from the QDM User Group.

For More Information

You can find current and past versions of the QDM and QDM User Group meeting information on the eCQI Resource Center QDM page.
