Semantic interoperability in Czech healthcare environment supported by HL7 version 3

Area of Science:

• Health Informatics
• Medical Informatics
• Healthcare Interoperability

Background:

• Czech healthcare data exchange relies on national standards.
• A pilot Semantic Interoperability Platform (SIP) was developed to enable international standard utilization for electronic health record systems (EHR-Ss) exchange.
• This initiative was part of the national "Information Society" research project.

Purpose of the Study:

• To build a pilot Semantic Interoperability Platform (SIP) for exchanging health information among Czech electronic health record systems (EHR-Ss).
• To evaluate the utilization of international standards and nomenclatures in the Czech healthcare environment.
• To facilitate the transition from national to international data exchange standards.

Main Methods:

• Formulated requirements for the SIP.
• Analyzed communication standards including openEHR, HL7 v3, and DICOM, selecting HL7 v3 for health record exchange.
• Integrated two EHR systems, WinMedicalc 2000 and ADAMEKj EHR, into the pilot environment.

Main Results:

• Developed HL7-based local information models for the integrated EHR systems.
• Mapped local concepts to HL7-supported coding systems (LOINC, SNOMED CT, ICD-10).
• Implemented and tested data exchange using HL7 v3 messages for patient administration data, utilizing a configurable HL7 Broker.

Conclusions:

• Nationwide implementation necessitates adopting international coding systems and developing migration guidelines.
• The pilot proved the feasibility of the HL7 v3-based approach for semantic interoperability.
• Full integration into the European e-health context requires substantial effort and commitment.
