Unfortunately, applicants are choosing programs based on brand and convenience, and not as much on education. It's the difference between
the outer scorecard and the inner scorecard, as Buffett likes to say.
“I say ‘Lookit. Would you rather be the world’s greatest lover, but have everyone think you’re the world’s worst lover? Or would you rather be the world’s worst lover but have everyone think you’re the world’s greatest lover?'” — Warren Buffett
If one gives up one year of attending-level income (plus the decades of compounding which would increase its real value 2-3 times), one had better know why. It's one of the most expensive investments in one's life, and one should treat it accordingly, not just throw out the money blindly. One should get the best education one can for that money, with the best return on investment, both in happiness and income. Most anesthesiology fellowships have an abysmal ROI (critical care included).
One more secret: there is no rush! One can go back and do a fellowship 5-10 years after graduation, if it's truly important for one's career. It may be inconvenient, but it's doable, and it's probably much wiser than jumping blindly into one, after residency, like most greenhorns do, based on whatever stories they hear during residency from ivory tower academics, instead of their own real-life attending experience.
On topic:
OP, I don't know any of these programs except from hearsay. I would drop Vandy (and any other program that is too involved with
midlevel education). I would definitely interview at a program I hear good things about
from former grads, and/or one that tends to attract fellows from big name residencies. It seems that Michigan ticks those two boxes (besides the impressive education).
Most (but not all) anesthesiology-CCM programs offer a decent education, because the best education comes from self-study and experience, so all they have to do is to not overwork the fellow, and have enough pathology and well-educated faculty.
Forget location, focus on brand and education. And if you cannot get into a good program this year, wait. Don't just list/accept any CC fellowship. Critical care is not competitive, and you may get into a better one post-match.
