Modern eHealth infrastructures are composed of a multitude of digital systems that process information from business processes in the health care sector. These systems need to exchange data in order to comprehensively support a patients journey through the health care system. Ambiguous, contradicting or misinterpreted data can harm a patients life in the worst case. Therefore interoperability standards are needed to harmonize the data exchange among all involved systems. As a secondary effect, FHIR defines and unifies technical terms on the domain level.

openIMIS is dependent on a variety of other information systems in a national eHealth landscape. As part of the Modular Transformation of openIMIS, all communication interfaces between different modules, internally and to the outside world, are to be based on the data structures defined in FHIR.
Currently openIMIS supports HL7-FHIR in Release 3 (STU3) for selected business processes. As soon as major partners in the ecosystem indicate a switch to FHIR Release 4 (R4), openIMIS will make plans to follow.
HL7 FHIR resources are structured in modules (not to be confused with openIMIS modules) on five levels. the following table will provide links to the resources and modules in their respective version and list the ones that are relevant for openIMIS.
