Comparison of openEHR and HL7 FHIR standards

Jacek Kryszyn, Waldemar T. Smolik, Damian Wanta, Mateusz Midura, Przemysław Wróblewski


Health informatics is characterized by the need to
securely store, process and transmit large amounts of sensitive
medical data while ensuring interoperability with other systems.
Among many standards used in such systems there are two which
have gained interest in recent years and cover most of those
needs: openEHR and HL7 FHIR. In this paper, both standards
are discussed and compared with each other. The architecture of
both systems, the similarities and differences, methods of data
modeling and ensuring interoperability were presented.
