Now Available: Clinical Quality Language (CQL) Style Guide

September 26, 2018 - 6:13pm

The Centers for Medicare & Medicaid Services (CMS) has published the Clinical Quality Language (CQL) Style Guide to the eCQI Resource Center.   

CMS developed the CQL style guide to support the electronic specification and maintenance of electronic clinical quality measures (eCQMs) that clinicians and hospitals can potentially use for reporting to CMS quality programs via certified electronic health records (EHRs). This style guide is intended to be used as a reference for measure stewards or developers who are developing or specifying eCQMs for potential future inclusion in CMS programs to align with CQL standards and best practices.

The purpose of the CQL style guide is to facilitate standardized expression of measure concepts across eCQMs and to promote consistency across eCQM logic using CQL. The guide includes information on standards and best practices for the use of CQL, and specifically libraries, definitions, aliases, argument names, and functions within the CQL framework.

Questions on the CQL style guide should be directed to the eCQM Issue Tracker.
