Information and Communication Technology - Guideline 92. eHealth interoperability at institutional, national and international levels
The institution’s various electronic health applications are interconnected through standardized interoperability mechanisms with consistent information flow to ensure complementarity of services and no contradiction or duplication of data. All applications operate in harmony with the social security information system including disability benefits when relevant, and with the national health services and/or national health insurance architecture.
eHealth interoperability covers institutional, national and international system interaction.
Established international standards and coding systems are implemented from the beginning of any development and deployment. HL7 international standards guide information package, communication from one party to another, setting the language, structure, and data types for seamless integration between systems. DICOM (Digital Imaging and Communications in Medicine) is the international standard to transmit, store, retrieve, print, process, and display medical imaging information. LOINC is the universal standard for identifying health measurements, observations, and documents. SNOMED CT is a systematized nomenclature of clinical terms. These capabilities enable the institution to be integrated with national health services and/or national health insurance systems.
