HL7-to-FHIR Integration using InterSystems IRIS

Details

The video presents a practical demonstration of integrating HL7 to FHIR using InterSystems IRIS. The walkthrough details include setting up a Docker container, configuring services and business processes within the IRIS Management Portal, and deploying custom code via VS Code. The core function demonstrated is transforming incoming HL7 messages into standardized FHIR resources and sending them to a local FHIR server. The demonstration covers several critical steps: testing with sample HL7 messages, validating the resulting FHIR bundles using an HL7 Validator, adjusting production settings for various transmission modes, and finally confirming successful data transmission by querying the FHIR server using Postman. This technical approach provides a concrete solution for migrating medical data exchanged in legacy HL7 formats into modern FHIR resources. Such knowledge is highly relevant to solving interoperability challenges within Japanese healthcare IT systems, offering practical insights into data mapping and validation processes at an operational level.
