eCQI Standards

About electronic Clinical Quality Improvement standards

Standards are critical to data consistency, validity and interoperability. Their use makes it easier to:

  • Share information
  • Develop software
  • Integrate data
  • Implement systems

Standards, in the context of health IT, refer to agreed-on file formats for electronic documents, messages, and other healthcare related data elements. Click here to learn more about Health IT standards in general. Standards constantly improve so that more sophisticated data can be captured, used and analyzed.  Click here for a complete list of eCQM Standards and Tool Versions by year.

While eCQI is made up of eCQMs and Clinical Decision Support (CDS), you’d think both use the same standards, but they don’t. It’s important to understand the difference.

eCQM standards

Current CDS standards:

  • Virtual Medical Record (vMR) data model and templates
  • Health eDecisions (HeD) CDS Knowledge Artifact Specification (KAS)
    • Rules, order sets, documentation templates
  • Health eDecisions (HeD) Decision Support Service (DSS) and Implementation Guide

    QDM v5.3 represents a significant change from prior production versions as it no longer contains any logic expression. Previously published versions of the QDM (through version 4.3) included the data model and logic required to compare one data element to another. Beginning with the QDM v5.0 Draft for use with CQL testing, the QDM includes only the data model, whereas this and future versions require the use of CQL as a separate method for expressing logic. QDM v5.02 and v5.03 included minor changes for use with CQL testing. Version 5.3 is the production version for CQL-based eCQMs.
