HL7 Clinical Quality Language (CQL)-based Health Quality Measure Format (HQMF) Implementation Guide (IG)

eCQI Tools


The CQL-based HQMF IG constrains the HL7 HQMF IG by utilizing both a domain analysis model called the Quality Data Model (QDM) and an expression logic called CQL. QDM allows quality measure developers to describe clearly and unambiguously the data required to calculate quality measures. QDM data types are mapped to the HQMF templates. CQL allows the sharing of unambiguous logic among eCQMs and can be used with multiple data models.
