When I did pentesting I couldn’t tell you how many times I’ve reviewed apps that used real patient data in their UTM and dev environments. Absolutely a big HIPAA violation to anyone who isn’t a covered entity. This is going to be a huge suggestion in reports for that kind of work.

#22When they say "Most EHRs use a message format called HL7v2, which is ugly and tedious to type." they aren't kidding, here's an example of it:

I've worked a lot with DICOM which has plenty of warts (as expected with a 30 year old living standard), but HL7 is a bit much for me. At least FHIR and DICOMweb are considerably saner.

no shot anyone actually types this out, right? surely this must be generated by machines for machine ingestion.

The wire format is a bit messy and hard to read. But developers mostly work through libraries like HAPI which have a decent API.
Re: Simulated Hospital
#26This would be such a great use case for an LLM.
Why?
Re: Simulated Hospital
#27Nice effort, and its something. But something may not be good enough to solve hard problems. Can simulated hospital simulate efforts by staff to quickly add into many charts a medication Rx - by taking one patient note and copying 1 note, then pasting that into several? Does it simulate staff forgetting the dosage was not edited after pasting into all those charts ? Or staff not logging out of their userID, to avoid…
In your view, what was the purpose of your comment? Who are you lecturing?

I designed HL7v2 and v3 (xml based) parsers in Mirth. It was horrible, but boy did I learn a ton. Subtle bugs could lead to scary outcomes like drug doses being way off. Seeing the string “PID” still causes nightmares.

HAPI is amazing.
