Oh, man. Who lied to you about healthcare compensation?
Just go check glassdoor.
Major IT companies bail on healthcare because margins suck and it's enormously regulated.
I give you, for instance, DICOM, Hl7, Meaningful Use, Infobutton, or any of the other half-useless dead-letter, best of the 80s-era mainframe technologies that are required to meet healthcare regulatory burden.
The best thing that's come out lately if FHIR, which is 9 years old and still doesn't qualify an EHR for meaningful use. Instead, it's all pipe-delimited TCP/MLLP and WTF.
