I do a bit of work with Epic as a 3rd party vendor, its interesting to say the least. The UX is pretty bad, but an internal human factors group seems to be gaining influence and decision making power in the organization. Its also odd because even as an older company, most of their workforce is in their mid 20's and early 30s, so change is coming eventually. That said, a bad Epic install will absolutely bankrupt a hospital.

And not to be a pedant, but Epic's big break was with Kaiser, Hopkins came a years or two later.
