New to HAPI FHIR - Standard Practice for extracting data from data sources?

[NickW]

Hello.

My organization is currently looking at installing and configuring a HAPI FHIR server. And one of the biggest questions I find myself trying to answer is how HAPI is supposed to pull data from from our EHR or data source.

Does HAPI have a way to make calls for data against other data sources? Can it be configured to make HTTP calls to another application or database out of the box? Does such a feature need to be custom built?

Or is it necessary to configure a connection via an integration engine?

Any advice or information would be greatly appreciated.
And please let me know if I need to elaborate on this question for clarity. I’m happy to do so.

Assuming you're talking about the HAPI FHIR JPA server, this module acts only as a server/repository. Any code to pull data from it or push data to it needs to be written on top.

There are a few specific exceptions to the "it's just a server" comment:

- Subscriptions will make outgoing calls

- The Bulk Import module can make outgoing calls to fetch data from a compliant endpoint

- The HAPI FHIR client module can be used to build clients

..but overall, think of HAPI FHIR as the FHIR Server, whose APIs can be called to store data, fetch data, discover data, etc.

Cheers,

James

Hey James,

Thank you for this. This advice certainly helps me to level-set out-of-the-box expectations, next time this topic is brought up.

Much obliged, and have a great day.

Same case I am also trying. Need to make my EHR as FHIR complaint. Do I need only JPA server module. Where to start from to achieve my target
