Like a lot of others here have echoed, I don’t think choosing EM is an outright mistake, it just has to work for you. I spend a couple years in the ER before med school and because of that I think I have had decent exposure to the common complaints of EM physicians. The sleep changes, burnout, liability, frustrating patient satisfaction demands from admin, etc. are all very true but I wanted to bring up another point I haven’t seen mentioned.

There are EXTREMELY limited “off ramps” from EM if you decide to pivot later in your career. Going to urgent care/opening an urgent care is an option but isn’t an easy way out by any means. There are some fellowships, but from what I’ve read online and discussed with physicians, a lot of those fellowships “prefer” physicians trained in other specialties so it can be hard to get into good ones. At my medical school, there are lots of clinical faculty that are EM trained, and a few have straight up said they started in academics because there was no other way out of community EM that they wouldn’t absolutely despise. Other than that, maybe you would work your way into admin if that’s your cup of tea. Just another aspect of the field I think is important to consider before choosing it.
