Interoperability's Next Chapter: Why Going FHIR-first is Urgent
Interoperability's next chapter - going FHIR‑first | Star Masterclass Star
A discussion was held regarding the transition from the established HL7 v2 standard to FHIR-first interoperability.
Summary
In healthcare, interoperability has become the essential technical foundation for AI-driven applications and digital products. Yanick Gaudet, an HL7 co-chair, explains that due to data fragmentation across various systems, migrating to the FHIR standard is critical for modernizing healthcare IT.
Key Players
Details
For decades, connected care and interoperability have been discussed in healthcare. However, by 2026, interoperability is no longer just a vision; it is the technical foundation required to power AI-driven applications, clinical trials, and advanced digital health products. Yanick Gaudet, Star Interoperability Solutions Architect and HL7 co-chair, explains that while standards like HL7 v2 have been widely deployed workhorses, they are often loose and heavily customized site by site. In contrast, FHIR is a modern, API-driven standard built around well-defined resources (e.g., Patient or Observation). This profile-based approach strictly constrains how data elements are structured and coded, enabling more consistent and predictable data exchange with less bespoke mapping effort. This makes FHIR ideally suited for today's ecosystem of cloud services, mobile apps, and AI-driven analytics, making interoperability a critical capability for developing new digital products quickly and reliably.
