Extending the OMOP Common Data Model for Critical Care Medicine: A Framework for Standardizing Complex ICU Data Using the SCCM C2D2

This study describes the development of a framework for extending the Observational Medical Outcomes Partnership (OMOP) common data model to accommodate the unique data requirements of critical care. The authors collaborated with the Society of Critical Care Medicine's Critical Care Data Dictionary (C2D2) initiative to map ICU-specific data elements, such as continuous physiologic monitoring, ventilator parameters, and medication infusions, to standardized OMOP concepts.
