Hey. You can search around; there's a current Pitt CCM fellow & a former fellow @ Pitt on this board.
I did anesthesiology residency there, and am doing CCM fellowship in Michigan. In all honesty, I likely would have stayed at Pitt for fellowship if not for compelling personal reasons to head a bit west, since it would have been an easy transition. I did my four ICU months as required by residency, and then two elective months as a senior resident. I'm VERY happy where I am, and loved my time in the 'burgh. Since I only saw the fellows (albeit for 6 months) and didn't actually do the training, take this with a grain of salt:
Probably the single biggest name in ICU still; I interviewed away from Pitt, and literally EVERY program director asked "Why would you leave Pitt to do training elsewhere?" Stand-alone CCM department whose Chair is ICU section editor of JAMA, tons of money, huge research efforts, and Drs. Angus, Kellum, Kochaneck, Kahn, Pinsky and others will get you published. Clinically, you get exposed to EVERYTHING - the flagship (UPMC Presbyterian) has a 22 bed CTICU (the usual, along with ECMO, VADs, and IABP), SICU, SICU-overflow, 23 bed Trauma ICU, Neurotrauma ICU and two floors of Neurovascular ICU, along with a 28 bed Transplant ICU. AND on call, you cover the whole hospital for codes and rapid-response calls. Plain and simple, you'll see it at Pitt. And your attendings will come from surgery, medicine, anesthesiology, and emergency medicine. EVERY day (not weekends) you get a fantastic lecture, from experts. My impression is that you get outstanding exposure - whether or not you want it. There are too many beds for you to have residents working beneath you. You get all the procedures, 'cause they won't get done on their own. You can't help but learn everything. But in comparison to where I am now, Pitt seems to treat fellows as super-senior residents, whereas I feel I'm treated like a junior attending now. As a resident in the ICU at Pitt, I can remember maybe 3 or 4 instances in which I was rounding with a fellow as my "leader", and there are several ICUs in which you simply do not run rounds without the attending there. Sum total: great exposure, lots of clinical work, not a ton of autonomy.
