What is FHIR, and when would you still be dealing with HL7 v2?
5 min readUpdated 2026-08-15
Answer
Short answer
FHIR is a resource-oriented REST API with a defined set of resources, constrained for real use by profiles and implementation guides. HL7 v2 is the older pipe-delimited messaging standard that still carries most of the event traffic inside hospitals, so the two coexist and an integration engine translates between them.

- How would you get five years of history for a whole population out of a FHIR server?
- An ADT feed stops delivering discharge messages overnight. How do you find out and what do you replay?
