Same here, Random Resident. I loved MICU in my intern year. Absolutely hated every single month of SICU in my residency (mostly run by surgeons who used residents only for scutwork). But I love internal medicine, and I want to feel like a physician, not a stool sitter or a firefighter. And, long term, my guess is that at least 50% of anesthesiologists will end up either replaced by experienced CRNAs, or working at CRNA-level hourly rates. Unless the patient is ASA 4 (and possibly 3 for some procedures), we have made anesthesia safe enough to be practiced even by monkeys. It's just a matter of time. Just look at primary care physicians, except that those guys had the advantage of having their own patients, and their APRNs are way less militant. CCM is an escape route, an insurance for the future. It would also allow me to get my specialty diploma recognized in my home country, if ever needed.
I work in a renowned academic place, as an attending. For years, I have witnessed the decay of the status of the department in the eyes of the hospital and the surgeons. As a group, we get almost no respect from many of the surgeons. Even when we are respected, few of them treat us as equals. We push our patients' stretchers to the OR alone, even if working as solo attendings, making us look worthless in the eyes of the OR staff. We make up our own fluids, put on our own monitors, are being more and more ignored by the OR staff in the room (today I had 2 circulators in the room, and none of them moved a finger to help). Meanwhile everybody kisses the surgeons' butts up to their cecums. Some surgeons will interrupt our preop interviews like we don't exist. They would give us instructions about the kind of anesthesia they want, down to the level of "I want an LMA, not an ETT". Again, we are talking about board-certified attendings here. (As a resident or CRNA, these thunderstorms happen way above your head, so you don't know how good you have it.) The hospital admins overrule us when we occasionally cancel cases of well-connected surgeons, so we end up taking risks we shouldn't. If we are a minute late with getting the patient to the OR in the morning, a hospital middle manager will page us and treat us like kindergarteners, while the department will cut a part of our day's pay. And the list can go on. To quote Rodney Dangerfield, we mostly "don't get no respect". And it's not even worth complaining, because nothing changes except being branded as a troublemaker by your own department.
I will be doing CCM because I want to feel like a doctor again, not a valet for surgeons or periop monkey for CRNAs. I am not a prima donna, but I can't stand being treated like a doormat either. If that means being the primary attending for the patient, so be it. Even if it means never going back to the OR, or ending up in another academic place (which I'd hate, because I am a hard worker, not a CV padder or brown noser). The rest of the generic reasons you can find in similar recent threads.
Anesthesia incomes are going down. CCM salaries are going up. After the two intersect, private groups will suddenly become very interested in taking over ICUs. Same goes for the PSH, which might end up being paid better than some OR anesthesia.
