EHR Integration via HL7 / FHIR
How a hospital's EHR exchanges data with labs, radiology and insurers through an integration engine, translating between HL7 v2 and FHIR.
Drawing diagram…
What this diagram shows
- An integration engine sits between the EHR and every outside system
- Old systems speak HL7 v2, new ones use FHIR REST APIs
- Failed messages go to an error queue for review, never silently dropped
Prompt used
Flowchart for EHR integration: the EHR raises an event (new admission, lab order, discharge). The integration engine (Mirth Connect) receives it, validates and maps it, then routes it: HL7 v2 ORM messages to the lab system, DICOM worklist to radiology, FHIR Claim resources to the insurer API. Results come back as HL7 ORU or FHIR Observation and are written into the patient's record. Messages that fail validation go to an error queue for an integration analyst.
