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

July 2, 2018 - 10:10am

The Centers for Medicare & Medicaid Services has published the Quality Data Model (QDM) standard, version 5.4. 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 Fall 2018 (MAT v5.6). Measures produced using QDM v5.4 are anticipated for implementation in calendar year 2020, whereas QDM v5.3 is for calendar year 2019. 

QDM v5.4 contains the following changes from QDM v5.3, Annotated:

  • Added QDM datatypeinfo-icon Assessment, Order
  • Added “setting” attribute to QDM datatype Medication, Order
  • Removed the “method” attribute from all datatypes with a recommended or order context
  • Provided additional guidance to the use of the QDM datatype Device, Applied
  • Provided additional guidance for the use of the QDM datatype Symptom
  • Removed the “supply” attribute from QDM datatypesinfo-icon for which clinical data does not provide supply information
  • Removed the “anatomical approach site” attribute from several QDM datatypes
  • Retained the distinction between QDM categoriesinfo-icon Intervention and Procedure even though interoperability standards do not provide any differentiation between the two concepts
  • Merged three Communication QDM datatypes – Communication, Provider to Patient; Communication, Patient to Provider; Communication, Provider to Provider into a single QDM datatype, Communication, Performed
  • Provided some guidance on the use of the QDM substance category with existing use cases (blood product administration and exclusive breast milk feeding for newborn infants in the hospital)

Previously published versions of the QDM (through version 4.3) included the data model and logic required to compare one data element to another. With the implementation of Clinical Quality Language (CQL) in Fall 2017, the QDM includes only the data model, so this and future versions 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.
