My impression as a CA 2 AMG Anesthesia resident is purely a personal one.
At my institution we have two Anesthesiology/CCM attendings, and they both happen to be Non US physicians. They are very smart, and for the most part, are excellent teachers. They are very detailed in their treatment, which seems to be a recurring concept as I work with more and more intensivists (currently I happen to be on a Pediatric ICU rotation working with pediatric ccm-non-anesthesia attendings).
Attractive attributes of Anes CCM to me: Very sick patients, opportunities for many procedures in common with anesthesiology-CL,AL,intubations, vent management, resuscitations, transfusion medicine, pulmonary and cardiac medicine, post-op medicine, life-threatening diseases other than hemorrhaging parturients, eg acute respiratory distress,etc etc. ASA people seem to think it is the future direction for anesthesiologists. Fellowship is only one year long. Non-competitive currently-do it where you want to live. Maybe more respect as a physician later. Something to separate you completely from a CRNA. Opens the door to academics if you so desire etc. (as if it was hard to get a job at univ hosp anyways.)
Negatives to me:Currently finding its place as a specialty in private practice and even in academic setting. In my institution, Anes CCM docs take the pressure off the trauma surgeons by rounding, but it is clear that the trauma surgeons are considered 'the primary service' in the ICU. In private hospitals, it seems to be the pulmonologists who 'run' the ICUs out there, and I hear Anesthesiology CCM reimbursement is not super lucrative, either. I do not particularily enjoy the Infectious Disease aspect, and debating about how the cultures were drawn before or after the abx, or what abx, or what dose etc. etc.Oh yeah, do you like rounding, dictating, writing lists of orders, etc?
I am sure it would not *HURT* to do a ccm fellowship, but how much it would advance your career as an anesthesiologist is another question. But another question to ask is do you LIKE CCM? Would anyone even know what you were talking about if you told them you going to now become an ICU doc, and how is that different from the small-town internist/hospitalist who still runs the local little icu anyways?
Food for thought.
