Toward <scp>cross‐platform</scp> electronic health record<scp>‐driven</scp> phenotyping using Clinical Quality Language

Abstract

CQL supports the representation of arbitrarily complex phenotype definitions, and our execution engine implementation demonstrated cross-platform execution against two widely used clinical data platforms. The language thus has the potential to help address current limitations with portability in EHR-driven phenotyping and scale in learning health systems.
