Awesome CQL

A collection of awesome links, tutorials, and resources on the Clinical Quality Language.

Clinical Quality Language (CQL) plays an important role in the standardization and exchange of clinical rules. As a common language and syntax for expressing clinical concepts and calculations, it facilitates interoperability across different healthcare systems.

Mastering Clinical Quality Language is essential for healthcare professionals, developers, and quality measure analysts involved in the standardization and exchange of clinical rules.

I've published this list of important links to resources, tutorials, and examples on CQL in order to help everyone deepen their understanding, proficiency in, and appreciation of this language.
