Electronic clinical quality measures (eCQMs) use data electronically extracted from electronic health records (EHRs) and/or health information technology systems to measure the quality of health care provided. The Centers for Medicare & Medicaid Services (CMS) use eCQMs in a variety of quality reporting and value-based purchasing programs.

There are several benefits of using eCQMs:

  •  eCQMs use detailed clinical data to assess the outcomes of treatment by healthcare providers and organizations
  •  eCQMs reduce the burden of manual abstraction and reporting for provider organizations
  •  eCQMs foster the goal of access to real-time data for bedside quality improvement and clinical decision support

Hospitals and providers use eCQMs to provide feedback on their care systems and to help them identify opportunities for clinical quality improvement. eCQMs are also used in reporting to CMS, The Joint Commission, and commercial insurance payers in programs that reimburse providers based on quality reporting.

Find eCQMs:

Eligible Hospital (EH) and Critical Access Hospital (CAH) eCQMs and supporting materials are on the Eligible Hospital/Critical Access Hospital page of this website.  

Eligible Professional (EP) and Eligible Clinician eCQMs and supporting materials are on the Eligible Professional/ Eligible Clinician page of this website.

Report eCQMs:

For current CMS programs, Eligible Hospitals, Critical Access Hospitals, Eligible Clinicians, and/or Eligible Professionals must use the most current version of eCQMs when reporting eCQMs. For hospital reporting guidance, visit Quality Net  and the Quality Reporting Center for specific program reporting education. For clinician reporting guidance, visit the Quality Payment Program website and the Quality Payment Program Resource Library. For information about the Promoting Interoperability Program, refer to the CMS Promoting Interoperability Program webpage.

For HHS programs using eCQMs, refer to specific program requirements.eCQI Graphic for Healthcare Goals

Many different organizations may participate in the development and maintenance of eCQMs.The CMS Measures Management System is a standardized system and provides details on the process for developing and maintaining the quality measures used in CMS's various quality reporting and initiative programs. Information on the CQM and eCQM development lifecycle is available in the Blueprint for the CMS Measures Management System (Blueprint) and on the eCQM Lifecycle webpage.

eCQM Lifecycle:

The eCQM Lifecycle is a series of phases eCQMs progress through when being developed, tested, implemented, and updated. CMS provides several opportunities for stakeholders to engage throughout the measure lifecycle. 

Updates to eCQMs:  

CMS requires eCQMs approved for CMS programs to be updated annually to reflect changes in evidence-based medicine, code sets, and measure logic. CMS works with measure stewards, measure developers, and users of the eCQMs to ensure necessary changes are reflected in the Annual Update. Additionally, CMS may provide addenda to the eCQM Annual Update periodically within the year to ensure updated code systems are reflected in the eCQM specifications and supporting materials.

Structure of eCQMs:

To be reported from an EHR, eCQMs are made of electronic specifications. Health Quality Measure Format (HQMF), a Health Level Seven International (HL7) standard, is used for electronically documenting eCQM content. These electronic specifications include:

  • Computable representation of the eCQM: Contains important details about the measure, how the data elements are defined, and the underlying logic of the measure calculation. The files include:
    • HQMF XML syntax. The HQMF includes a Header and a Body. The header identifies and classifies the document and provides important metadata about the measure. The body contains eCQM sections (e.g., definitions, population criteria, supplemental data elements).
    • CQL
    • Expression Logical Model (ELM) XML document
    • ELM JavaScript Object Notation (JSON)

  • The Human-readable representation of the eCQM displays the eCQM content in a human-readable format directly in a web browser, Hyper Text Markup Language (HTML) file (.html). This file does not include the underlying HQMF syntax, but the narrative content at the top of the HTML is extracted from the HQMF header.

  • Value sets and direct reference codes (DRCs) convey specific coded values that are allowed for the data elements within the eCQM. Value sets are identified by an object identifier (OID) and include several metadata elements. The value set includes a list of codes (i.e., the value set “expansion code set”) acceptable or valid for a specific data element in the measure, descriptors of those codes, the code system from which the codes are derived, and the version of that code system. DRCs are specific codes that are referenced directly in the eCQM logic to describe a data element or one of its attributes. Value sets and DRCs are found in the VSAC.

Naming eCQMs:

CMS created a unique “CMS eCQM Identifier” to name eCQM files. The naming convention adds the eCQM identifier assigned to the eCQM in the Measure Authoring Tool (MAT) with the “eCQM Version Number”. “CMS” is placed in front of the number. The eCQM Version Number is used to indicate the published version of the eCQM. For example, based on this naming convention, Eligible Professional measure (NQF0056-Diabetes: Foot Exam) would be CMS123v1 for the first version of the measure.

Binding Parameter Specification (BPS)

Category: Implementation

The value set Binding Parameter Specification (BPS) is generated by the National Libray of Medicine(NLM).  It is a record of the value set metadata information that defines the value set code lists specified by published CMS eCQMs. Measure implementers and vendors can use the BPS to track versions and other parameters that define the value set code lists for each eCQM release. The BPS contains the same information as its predecessor, the discontinued Data Element Catalog (DEC), as well as additional parameters. Users can access the BPS metadata file, for any released set of CMS eCQM value set files, through the NLM's Value Set Authority Center Downloadable Resources.


Category: Development, Testing
Who Uses Tool: Measure Developer

Software tool that allows eCQM developers to test and verify the behavior of their eCQM logic. The main goal of the Bonnie application is to reduce the number of defects in eCQMs by providing a robust and automated testing framework. The Bonnie application allows measure developers to independently load measures that they have constructed using the MAT. Developers can then use the measure metadata to build a synthetic patient test deck for each measure from the clinical elements defined during the measure development process. By using measure metadata as a basis for building synthetic patients, developers can quickly and efficiently create a test deck for a measure. The Bonnie application helps measure developers execute the measure logic against the constructed patient test deck and evaluate whether the logic aligns with the intent of the measure.

CQL-to-ELM Translator Reference Implementation

Category: Implementation

The HL7 CQL specification defines both a high-level, author friendly syntax for expressing clinical knowledge, as well as a machine friendly, syntax-independent canonical representation of clinical knowledge called Expression Logical Model (ELM). The high level syntax is designed to support measure and decision support authors, while the canonical representation is designed to support point-to-point sharing and machine processing applications.

The specification describes a formal mechanism for translating the high-level CQL syntax into the canonical ELM representation. This project provides a reference implementation of that translation. The translation component is designed to support use within an Integrated Development Environment (IDE), and has several options and features focused on providing translation support in such an environment. The reference implementation is intended to be used in support of CQF implementations as a tool to enable CQL output to be uniformly and automatically translated into ELM XML or JSON documents for sharing and distribution to support implementation, integration, translation, and execution of CQL-based artifacts.

The CQL-to-ELM Translator is substantially complete, supporting all language constructs of the latest version of CQL (Release 1 STU 2 (1.2)), as well as a broad range of functionality to support use of the translator in an Integrated Development Environment. Implementations making use of the translator can submit issues and track resolution progress through the Issues tracker in the Github repository.
