I know, I know, I'm against ER fellowships.
Not practicing in the ER for 2 years seems like a huge negative. There goes your peds knowledge, the ophtho skills, the ortho reductions, the Ob-Gyn knowledge, etc.
If you want to practice ER, and want extra ICU experience, why not go to a four year program and make that your emphasis for all of your electives.
ICU knowledge is only applicable to a small part of what we do. Septic patient? Give lots of fluids. How much? Lots, and get them the heck out of here.
A lot of time on ICU patients is managing line infections, weaning vents, and deciding what antibiotics to give based on culture results. What antibiotics should we give them in the ER? Lots of them, strong ones that kill everything, and get them the heck out of here.
I'm not demeaning ICU docs. They have one difficult job. However, some people have the mistaken impression that they deal with only acute issues. I was surprised to run into a lot of really chronic problems with patients on ICU patients. It seemed that medical ICU was 50% chronic care issues (trach patients, vent dependent muscular dystrophy patients and chronically ill patients who land in the ICU every 2 months and spend half their lives in the hospital).
If you like the ER, train in the ER. If you like ICU, an internal medicine residency or anesthesiology residency with a fellowship is going to train you better for the ICU, and ultimately, get you more respect from your colleagues in the ICU.
