Abstract
As global healthcare systems strive for interoperability, two leading standards—openEHR and HL7 FHIR—have emerged with distinct strengths and limitations. openEHR excels in semantically rich, longitudinal clinical data modeling and persistence, while FHIR enables scalable, API-driven data exchange across systems. However, their divergent focus—data at rest vs. data in transit—creates challenges in achieving end-to-end interoperability.
This paper compares the two standards across key dimensions such as data modeling, query capabilities, governance, and exchange protocols, highlighting potential collision points. It then presents Carefluence’s approachto bridging this gap through a standards-aligned integration platform that translates structured openEHR data into FHIR-compatible APIs. By harmonizing semantic integrity with transport-layer accessibility, Carefluence enables healthcare systems to converge these standards into a unified, interoperable ecosystem.
