In my world they sure are. Want health records on your iPhone? Well that comes via FHIR. You can even see the FHIR resource JSON in the Health app.

But there are many systems in a hospital. And as EuphoricEmu pointed out within the hospital, admits, discharges and movements throughout the hospital are still done via HL7v2 (a delimited and structured format).

Additionally, I would absolutely NOT build a new system on HL7v2 at this point in time. I would only use it to integrate with existing systems.

Also, I do know of EHR systems that use FHIR for their internal data storage format.

Yup, there are a few EHR vendors that have some limited support. Intersystems’ whole platform is shifting towards have pure native support for FHIR. It’s still very rough and to into the weeds of things you sadly have to delve into that very old language (objectscript = MUMPS). But thankfully there bindings for more modern languages for it.

Unfortunately consumer-facing use cases are the ones big EMR vendors like Epic are focusing on with FHIR, push is often neglected or left out meaning we still have to rely on good old HL7v2 to get real time feeds out of the system.

[EuphoricEmu]

Yes exactly! Since patient movement within a hospital is done primary with v2 and then hours or even days later a patient summary CCD might get sent across. Unless you’re dealing with encounter based CCDs. But those still aren’t live.

FHIR Subscriptions do exist.
