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, QDM attribute, or QDM category and datatype data element.

The data elements provided are for use in eCQMs for 2019 and 2020 Performance and Reporting periods. Information contained within the DERep is derived from the eCQM specifications, Quality Data Model (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. In the eCQMs for the 2019 Performance and Reporting period, QDM Version 5.3 information is displayed. In the eCQMs for the 2020 Performance and Reporting period, QDM Version 5.4 information is displayed.

eCQM Data Element

The eCQM data elements provide 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.

eCQM

The eCQM 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 Attribute

The QDM Attributes filter provides a listing of all the QDM attribute definitions that can be reused in QDM datatype definitions in eCQMs for CMS quality reporting. Each attribute includes specific details about QDM data elements including the QDM definition and where it is used within data elements.

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 consists of a single clinical concept identified by a value set or direct reference code (DRC).

QDM Datatypes

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