Thinking in FHIR: The Curious Case of the Encounter++
summary
Legacy HL7 V2/CDA messages map to FHIR resources (Patient, Encounter, DiagnosticReport, Observation, DocumentReference/Binary, Account, Coverage) and the practical solution packages them: trigger V2 events create a FHIR subscription notification that sends a bundled payload of the encounter, patient and related resources; clients retrieve full encounter context with a single bundle post query rather than many GETs. This hybrid approach avoids a CDR, fits existing infra, reduces chattiness, and proves workable for gradual FHIR adoption.
