Not OP but I can tell you that due to the object size limitations of FHIR objects, document exchange is just not feasible. Using FHIR to register a patient is pretty pointless currently as every older and larger hospital sends HL7v2.

RHIOs building gateways for 3rd party apps is very much the future of FHIR. But they’ll still be interacting with that crufty legacy system.

Just my own two cents.

Thanks! I was not aware of the object size limitations nor of RHIOs

Are RHIOs using engineers/consultants to wrapped legacy systems then devise methods to make accessing that data easier -- how are RHIOs using FHIR and legacy system to construct the future of medical data interoperability?

RHIOs exist predominantly to allow the exchange of patient information between participating hospitals or even regions. I personally only have insight into how two RHIOs operate. Both are very interested how they can turn FHIR into another avenue to distribute patient information.

The issue is that most EHR/EMR vendors have very limited limited interoperability with FHIR. As a lot of these vendors are struggling with CCD 2.1 implementations. The exciting space is allowing patients through 3rd party apps to request specific information or even send it to the HIE (RHIO in this case) and let there GPs know of certain events.

Which means a lot of work to bend over backwards to get APIs exposed for these 3rd parties.
