Collaborative Measure Development (CMD) Workspace

CMD Workspace

The CMD Workspace brings together a set of interconnected resources, tools, and processes to promote transparency and better interaction across stakeholder communities that develop, implement, and report electronic clinical quality measuresinfo-icon (eCQMinfo-icon).

CMD Workspace Components

The CMD Workspace will be comprised of five modules to assist clinicians, eCQMinfo-icon developers, implementers, and submitters during the entire eCQM lifecycle, from initial measure concept, through development, implementation, and reporting to CMS. Goals of the CMD Workspace are to:

  • Provide detailed data element definitions to support implementation
  • Achieve harmonizationinfo-icon across measures, data elements, and value setsinfo-icon
  • Improve alignmentinfo-icon of measure concepts with clinical need and newly published guidelines
  • Demonstrate how new measures fill existing quality reporting gaps
  • Increase involvement by clinical experts and EHRinfo-icon vendors during measure development
  • Offer transparency of test results during measure development
  • Provide notification of updates to measures under development

Access existing measures and the measures under consideration in the CMS Measures Inventory Tool (CMIT).


Available Components

eCQMinfo-icon Data Element Repository (DERepinfo-icon)

An online, searchable eCQM Data Element Repository provides all the data elements associated with eCQMsinfo-icon in CMS programs, as well as the definitions for each data element. This information will improve clarity for those implementing eCQMs.

Future Components

eCQM Concepts

The eCQM Concept Workspace will give users the ability to submit new measure concepts, align new measures with Meaningful Measures criteria, and identify whether similar measures exist. Feedback can help guide the measure developerinfo-icon to refine the concept and purpose behind a new measure to better suit the needs of the quality measurement reporting community.

New eCQM Clinical Workflow

Groups will be able to access all the measure development tools in the Collaborative Development Workspace and work in an iterative manner to perform measure development activities. Experts interested in a measure, measure endorsers, and other stakeholders can provide early comments, clinical workflow concerns, and guidance during the development lifecycle. Lessons learned from previous measure development efforts can help developers address implementation-specific issues that arise during development.

eCQM Test Results

The Draft Measure Test Results will offer transparency into the feasibility, reliabilityinfo-icon and validityinfo-icon testing, a testing scorecard, and additional characteristics of test sites, including types of health ITinfo-icon used, number of test sites included, and rating of each data element in the testing process for each measure.

Subscribe to CMD Workspace Updates

CMD Workspace participants will be able to sign up for alerts on the progress of evolving measures within a specialty area.

eCQMinfo-icon Data Element Repository (DERepinfo-icon)

The eCQM Data Element Repository (DERep) provides all the data elements associated with published and tested eCQMsinfo-icon for use in CMS quality reporting programs as well as the definitions and clinical focus for each data element. An end user can sort information by data element, eCQM, union, QDM attributeinfo-icon, or QDM categoryinfo-icon and datatype data element.

The data elements provided are for use by Eligible Professionalinfo-icon/Eligible Clinicianinfo-icon and Eligible Hospitalinfo-icon/Critical Access Hospitalinfo-icon eCQMs for 2019 CMS quality reporting and performance periods. Information contained within the DERep is derived from the eCQM specificationsinfo-icon, Quality Data Model, Version 5.3, and the Value Setinfo-icon Authority Center (VSACinfo-icon). Each eCQM data element includes information about the value set, the direct reference code (DRCinfo-icon), the QDM datatypeinfo-icon, and the QDM attributesinfo-icon used by that data element.

eCQMinfo-icon Data Element

The eCQM data elements provide a listing of all data elements used in eCQMsinfo-icon for 2019 CMS quality reporting and performance periods. Each eCQM data element includes information about the value setinfo-icon, the direct reference code, the QDM datatypeinfo-icon, and the QDM attributesinfo-icon used by that data element.


The eCQM filter currently provides a list of 66 eCQMs in CMS programs - 16 Eligible Hospitalinfo-icon/Critical Access Hospitalinfo-icon and 50 Eligible Professionalinfo-icon/Eligible Clinicianinfo-icon measures. 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.

eCQM Unions
The eCQM Unions filter provides a listing of the eCQM unions represented in the Clinical Quality Language (CQL)info-icon of the eCQM specificationsinfo-icon. For each eCQM unioninfo-icon, the data elements contained within the eCQM union are listed. The eCQM union operator within the CQL is used to combine two or more data elements, arguments or expressions onto a list, such that any item contained in the combined list fulfills the criteria of the union. In the CMS113v7 Medical Induction Medication union example below, a medication contained within the combined list of Oxytocin and Dinoprostone will fulfill the criteria of the union.

Medical Induction Medication:
  • ["Medication, Administered": "Oxytocin"] union ["Medication, Administered": "Dinoprostone"]

  • Note: The eCQM unions shown do not include the CQL logic criteria to fulfill them, or elements present in the embedded logic of the union. For each eCQM union, the eCQMs that use the union are listed. Please refer to the respective eCQM specificationinfo-icon for complete logic criteria associated with the unions.

    QDM Attributeinfo-icon

    The QDM Attributes filter provides a listing of all the QDM attribute definitions that can be reused in QDM datatype definitions in eCQMs for 2019 CMS quality reporting and performance periods. Each attribute includes specific details about QDM data elements including the QDM definition and where it is used within data elements.

    QDM Categoriesinfo-icon and QDM Datatypesinfo-icon

    The QDM Categories and QDM Datatypes filter provides a listing of all QDM categories and datatypes used in eCQMs for 2019 CMS quality reporting and performance periods. For each QDM categoryinfo-icon and datatype, the page provides the respective definition along with the available attribute groupings for the selected QDM datatype. A QDM Category consists of a single clinical concept identified by a value set or direct reference code (DRCinfo-icon). A QDM Datatype is the context in which each QDM Category is used to describe a part of the clinical care process.
