Having seen countless cases of poor patient management by EM residents and attendings, there's a reason why Duke medicine residents often carry a bit of resentment about the EM folks.
I think that that says it all. However, let me tell you of an opposing perspective from "up above", despite your claims (which I take as absolutely true) of faculty being unprofessional enough to defame another faculty member to junior people (including students), which is professionally inexcusable and unacceptable. We were told that, per Andrew Muir and Diana McNeill, the EM residents should not complete every workup, as there was nothing being left for IM residents to do, save for data mining and following up lab results. As you may be unwilling to believe this, ask Kathy Clem. Xavier Preud'homme said the same thing - that he has been at Duke from well before there was true "EM" until after the program had been moving along, and it was leaps and bounds from before until after.
Finally, Duke IM residents, generally, have not distinguished themselves in the ED (showing up late, seeing less than 1 patient per hour, blatantly avoiding procedures, and then complaining about what they DO have to do), and, adding that to the disdain they show, it's a positive-feedback loop, and it's reiterated among highly impressionable second-year med students rotating through. There were a few that did indeed stand out, and did a fine job, but they were certainly in the minority.
Now, I'm making buckets of cash, and am easily following the standard of care, and that is due to the training I had at Duke. That in itself is directly a result of Susan Promes and her management of the program. You don't have to like her (as you evidently don't, but, in case you're not clear on it yet, one doesn't need to be liked to be effective), but,
de jure and
de facto, what she does works. And the faculty that would deride her don't have standing, or the guts to stand up for their principles, as she did, as I said, receive a teaching award from Duke.
UCSF is not a low-profile place, and they had many to choose from, and they chose her. Honestly, I think that the collective minds of UCSF, SFGH, and University Hospital have a bit more evolved perspective than a relatively young, newly-graduated doctor. What I'm saying is that it isn't a free pass with her, but you get your chops - guaranteed. Because people are rubbed the wrong way because it's not the typical coddling style amongst the "in crowd" (of which we were decidedly not invited into), that has little bearing on the results - even if it is that "I don't want to be like that", that's enough. I can tell you, whether people liked her or not (including all of the "EM residents" you know - whom I guarantee, for most at least, I know better than you), we all got what we needed. No one has yet to have flunked their board certification exams, among other benchmarks.
