I am doing an anesthesia CCM fellowship at the current time. I am finding that i spend the most time reading on nutrition, abx selection, and dialysis (CRRT). Other than that most things for me are intuitive because i had been doing them for years in the OR. There is a literature that needs to be read ie FACT, SAFE, CORTICUS, Early Goal Directed Therapy, but overall these are not mind blowing concepts for the anesthesiogist.
I had thought i would be quicker to consult but then i spent some time in a medical ICU and to be honest they seemed to consult more often.
The hours are not as good as when i was an anethesia resident.
