Measure Collaboration Workspace Frequently Asked Questions

What is the Measure Collaboration (MC) Workspace?

The Measure Collaboration Workspace is a collaborative portal that supports quality and IT staff at hospital and provider organizations to more easily implement and use eCQMs, and it is hosted on the eCQI Resource Center – which is the one-stop shop for the most current resources to support electronic clinical quality improvement.  

The MC 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 measures (eCQM). The MC Workspace is made up of four modules to support measure collaboration:

  • eCQM Concepts allows users to search existing measure inventories and submit new measure concepts for consideration
  • New eCQM Clinical Workflow allows users to review sample clinical workflows associated with new eCQMs and an opportunity to provide feedback on anticipated challenges
  • The eCQM Data Element Repository provides data definitions to aid in measure implementation and data mapping
  • eCQM Test Results provides transparency into how measures are tested and allow users to express interest in participating in eCQM testing activities
How do I learn more about using the MC Workspace?

The MC Workspace User Guide provides detailed information on using all of the modules.

Who sponsors this tool?

The Measure Collaboration Workspace is sponsored and maintained by the Centers for Medicare & Medicaid Services (CMS) within the U.S. Department of Health and Human Services.

Who are the primary users of the Measure Collaboration Workspace?

The Measure Collaboration Workspace is a public resource for use by clinicians, implementers (hospital/clinician clinical quality and EHR analysts and health IT vendors), measure developers, and the general public interested in electronic clinical quality measurement.

How often is the eCQM Data Element Repository updated?

The eCQM Data Element Repository currently provides data definitions for electronic clinical quality measures (eCQMs) used in CMS quality reporting programs for the 2019 Performance/Reporting Period and the 2020 Performance/Reporting Period.  The eCQM Data Element Repository will be updated each year to incorporate the eCQM annual updates.

Where do I go if I have a question or feedback about the Measure Collaboration Workspace?

The Measure Collaboration Workspace is hosted on the Electronic Clinical Quality Improvement (eCQI) Resource Center and is constantly improving to better meet the needs of its users. Please send any questions or feedback to

What happens to the comments that I submit on the eCQM Concepts, New eCQM Workflow, and the eCQM Test Results modules?

Comments submitted to the Measure Collaboration Workspace are sent to CMS and their measure developers for consideration. These comments may help provide suggestions not previously considered by the measure developers.  The comments collected in the Measure Collaboration Workspace are separate from the public comment obtained during the National Quality Forum (NQF) endorsement process and the federal rulemaking process. When measures progress to these phases when public comment is collected separately, commenting will be suppressed in the Measure Collaboration Workspace.

What is the difference between the electronic clinical quality measure (eCQM) data element repository (DERep) and the CMS data element library (DEL)?

The eCQM DERep is an online searchable repository that provides all the data elements and definitions associated with eCQMs used in CMS quality reporting programs by eligible hospitals, critical access hospitals, providers, and clinicians. The CMS DEL is the centralized resource for CMS assessment instrument data elements (e.g. questions and responses) and their associated health information technology (IT) standards, including the Minimum Data Set (MDS), Inpatient Rehabilitation Facility Patient Assessment Instrument (IRF-PAI), Functional Assessment Standardized Items (FASI), Outcome and Assessment Information Set (OASIS), Long-term Care Hospital Continuity Assessment Record and Evaluation (CARE) Data Set (LCDS), and the Hospice Item Set (HIS).
