FHIR Implementation Guide for EU Digital Green Certificate

Details

This guide explains the implementation guidelines for the EU Digital Green Certificate, based on the Fast Healthcare Interoperability Resources (FHIR) standard. It focuses on structuring critical data elements such as vaccination records and clinical documents. Technically, it describes how multiple related resources—such as `Composition-dgc`, `Patient-dgc`, and `Immunization-dgc`—are bundled together using resource types like `Bundle-dgc`. Specific profiles are defined for key data points, such as `Observation-CovidImmunity`, ensuring consistency and interoperability in vaccination records. Furthermore, the guide integrates multiple standard terminologies, including SNOMED CT, LOINC, and ATC. This allows coded information—such as vaccine names, diseases, and test results—to be attached via elements like `CodeableConcept-uv-ips`. This ensures that diverse medical concepts are handled uniformly. The content serves not only as a technical tutorial but also demonstrates concrete methods for data standardization in response to international public health challenges (pandemic response). It provides comprehensive knowledge necessary for implementation, including associated terminologies and concept maps, making it highly relevant for ensuring interoperability in Japanese healthcare IT.
