A few years ago I worked with a healthcare analytics company, creating an HL7 FHIR server as well as a de-identification product. The main problem with this area isn't technical - FHIR, HL7 etc all exist to meet these problems, rather the issue is buy-in/the market.

Most of those healthcare companies take the approach of "if it works don't touch it" or they where already bought into one of the existing large EPR's - which is why we ended up putting our product on the back-burner as the market wasn't there yet.
