The CQL Style Guide provides standardized expressions of measure concepts across eCQMs and promotes a uniform “look and feel” to eCQM logic using CQL. The guide focuses on a set of common best practices that have been implemented across CQL-based eCQMs in CMS quality reporting programs. The style guide also promotes the use of consistent language within the framework of CQL, including libraries, aliases, definitions, and functions, as well as guidance on other conventions, such as operator precedence. Measure stewards or developers who are developing or specifying eCQMs for future inclusion in CMS programs should align with these best practices.
