Electronic Clinical Quality Measure (eCQM) Data Element Repository (DERep)

The eCQM Data Element Repository (DERep) provides additional clarification for all the data elements associated with published and tested eCQMs used in CMS quality reporting programs as well as the definitions and clinical focus for each data element. An end user can filter information by data element, eCQM, Quality Data Model (QDM) attribute, QDM category, or QDM datatype data element.

The data elements provided are for use in eCQMs for 2019, 2020, and 2021 performance and reporting periods. Information contained within the DERep is derived from the eCQM specifications, QDM, and the Value Set Authority Center (VSAC). Each eCQM data element includes information about the value set or the direct reference code (DRC), along with the QDM datatype, and the QDM attributes used by that data element. The QDM information displayed for an eCQM reflects the version used in the development of the eCQM for a specific performance/reporting period. For the 2019 performance and reporting period, QDM Version 5.3 information is displayed. For 2020, QDM Version 5.4 information is displayed, and for 2021, QDM Version 5.5 Guidance Update information is displayed.

eCQM Data Elements

The eCQM Data Elements filter provides a listing of all data elements used in eCQMs for the selected CMS quality reporting and performance periods. Each eCQM data element includes information about the value set or the direct reference code, along with the QDM datatype and QDM attributes used by that data element.

eCQMs

The eCQMs filter currently provides a list of the Eligible Hospital/Critical Access Hospital and Eligible Professional/Eligible Clinician measures used in CMS quality reporting programs. The individual eCQM pages provide the measure rationale and a list of all the eCQM data elements associated with the measure and information about each data element.

QDM Categories

The QDM Categories filter provides a listing of all QDM categories used in eCQMs for CMS quality reporting. For each QDM category, the page provides the respective definition. A QDM Category is similar to a class of information (e.g., Medication, Procedure, Encounter).

QDM Datatypes

The QDM Datatypes filter provides a listing of all QDM datatypes available for use in eCQMs for CMS quality reporting. A QDM Datatype is the context in which each QDM Category is used to describe a part of the clinical care process. For each QDM category and datatype, the page provides the respective definition along with the available attribute groupings for the selected QDM datatype.

QDM Attributes

The QDM Attributes filter provides a listing of all the QDM attributes, i.e., metadata/information available for use with each QDM datatype in eCQMs for CMS quality reporting. Each attribute allows measure expressions for specific details about QDM data elements such as information about constraints, terminology binding, timing, and other requirements that provide clarity for what each eCQM data element requires for retrieval.

QDM Entities

Entities are not QDM datatypes or attributes. They represent concepts that can be used to specify details about the actor (or performer) of any QDM datatype. An eCQM can use the entities to provide further information required for an individual or organization actor to meet the measure’s criteria. Current QDM Entities include: Patient, Care Partner, Practitioner, and Organization.
