We don't use Epic for our clinic (no way can we afford it), but about 70% of the hospitals around us do. As affiliated clinicians we have logins to, like, 10 hospitals. The reason Epic is everywhere is it's infinitely configurable and part of buying into it is buying the configuration you want and need and being supported in its continued operation. Epic is apparently a bitchin' place to work.

Those warnings were undoubtedly added by the doctor's administrator, or whoever is top-of-the-foodchain of their Epic install.

There's a real dividing line in healthcare right now: clinicians who are good at computer and clinicians who are not. the ones who are not are experiencing a real kick in the nuts in their patient care because they have to give over an embarrassing amount of time to just entering shit in. The ones who are fresh out of medical school have never known any different so they just rip. It's a shame, really, because there are a lot of great doctors out there with a lot of experience and they can give patients about half as much time as the new kids because they sit there struggling with the EHR. Epic is better than most, and a well-tuned system uses a lot of scripting and workflow shenanigans to get out of the clinician's way.
