Problem
An interoperability hub that standardizes HL7 v2 flows into FHIR resources across a three-hospital network and private insurer ecosystem.
Solution
Problem
The client environment combined HL7 v2 messaging and multiple HIS platforms. Lack of FHIR alignment increased integration lead times and caused recurring data consistency issues.
Solution
We implemented MedLink FHIR Hub with an HL7 listener, FHIR mapping pipeline, consent and masking controls, and a centralized FHIR store. ADT, ORU, and ORM message families were normalized through reusable mapping policies.
Architecture Notes
- Terminology services automated SNOMED and LOINC code harmonization.
- Consent policies enforced scoped access and masking across downstream consumers.
- Full audit logging provided traceability for every transformation and data handoff.
Outcome
Integration timeline decreased from 12 weeks to 6 weeks. Cross-system data inconsistency dropped by 33%.
