HL7 FHIR Webinar: The Future of Health Data Exchange

Audience Assessment and Engagement
📌 The presenter used a virtual whiteboard session format, similar to a previous one at the HIMSS conference, to engage attendees.
🧑‍💻 Polls were used to gauge the audience, revealing that most attendees were primarily technical (0% caregivers in this specific session) and focused almost exclusively on interoperability (over 80% focus).
💡 Approximately 20% of attendees had already dug into the FHIR specification.

FHIR vs. HL7 V2 Interoperability
⚙️ Traditional HL7 V2 involves translating data models between systems (like HIS and Lab systems) requiring at least two translation steps and relying on workflow-oriented messaging.
🔄 FHIR (Fast Healthcare Interoperability Resources) allows for real-time, interactive access to data at the source of truth (e.g., HIS or Lab database) via an API.
➕ FHIR usage allows vendors to expose their data via a standardized API, enabling arbitrary developers to access the same information, promoting openness beyond proprietary stacks.

FHIR Implementation Lifecycle and Projects
📈 The concept of the Gartner Hype Cycle was referenced, placing FHIR currently climbing up the expectations curve, aiming for the Plateau of Productive Use.
🖥️ The Argonaut Project is a collaborative effort (involving Epic, Cerner, Mayo, etc.) focused on implementing a limited, US-centric version of FHIR resources related to the Data Access Framework (DAF) for Meaningful Use compliance.
🔬 Key Argonaut use cases include querying medication lists, problems, allergies, and lab results via profiled FHIR resources.

Real-World FHIR Workflows and Applications
🏥 In a device workflow, FHIR allows a bedside device to directly query the EMR (Epic/Cerner) via a query interface using the barcode data, potentially eliminating intermediate servers and stale ADT feeds.
➕ Devices can also create an Observation resource directly in the HIS, impacting data ingestion workflows positively.
☁️ The SMART on FHIR framework enables cloud-based applications to integrate securely. This allows a cloud application to present a portion of the user experience *inside* the EMR window in real-time (e.g., displaying cardiac risk charts based on real-time LDL/HDL values retrieved via FHIR).

Key Points & Insights
➡️ FHIR's primary advantage over HL7 V2 is enabling real-time, interactive access to the source of truth data within institutional walls, rather than just workflow-based message exchange.
➡️ To learn more, consult the HL7 FHIR website (specifically the Draft Standard for Trial Use #2) and explore the defined ~100 resources (like Patient, Diagnostic Report).
➡️ The Argonaut Project is leading the practical implementation by focusing on a limited set of key resources required for US Meaningful Use/DAF compliance, demonstrated by looking at specific `fhir.cerner.com` or Epic implementations.
➡️ SMART on FHIR facilitates powerful integrations where external cloud apps can co-mingle data and presentation layers within the existing EMR interface seamlessly.
