Thanks for the heads-up!

Do you know of a good way to leverage this API in a way that can be directly used by clinicians to pull and work with data?

You'll have to start by finding the FHIR web service endpoint URL for your EHR instance, as well as appropriate authentication credentials.

Client applications can be written using the HAPI FHIR library.
