CQL Formatting and Usage Wiki

The Clinical Quality Language (CQL) Formatting and Usage Wiki is a collaborative, community-driven workspace dedicated to the development and sharing of CQL formatting conventions, coding patterns, and best practices. It serves as a central resource for measure developers, health information technology (IT) implementers, and clinical informaticists to standardize how CQL logic is represented within electronic clinical quality measures (eCQMs) and other clinical decision support artifacts. The Wiki provides practical guidance on writing clear, consistent, and maintainable CQL, including examples, templates, and usage recommendations, helping ensure that quality measure logic is accurately interpreted, interoperable, and easier to implement across different health IT systems.
