The list is long, but here's the ones that count. My top four.
1) Columbia: Solid clinical trainig, decent didactics, excellent peds, okay regional, great opportunities for research/academics, chairman very approachable, residents seem happy, chance to moonlight, and a chance to enjoy a brief time in Manhattan (when I'm not catching up on sleep). Liked the residents, but there didn't seem to be a lot of camraderie. None-the-less, they seemed happy.
2) Duke: Solid Clinical training, solid didactics, excellent regional, great peds, the hospital is amazing, and the opportunities for research are excellent. Residents were great, and I had a blast hanging out with them while I was there. I'm not sure I want to live in Durham at this point in my life though. Beautiful place, gorgeous surroundings, fantstic beaches not too far away, but I've lived in smaller cities for a long time and am curious to try out something different (Manhattan is very different). It was a tough and close tie between the two which I may change in a fit of last minute maddness.
3) BI: Loved the people. Staff were great to talk with, residents were all approachable and very happy. Peds was amazing, and the clinical training was solid. Research is okay, but being in the harvard system affords a lot of opportunites to connect with others locally, which is a great potential. Living. . . Boston summers are fantastic. A very close 3rd.
4) Cornell. I liked the residents here the best. They were the closest to the kind of people I'm surrounded by now and feel I'd fit in with best. Opportunities for research are there, but no-one specifically in the area I'm interested in. Excellent regional, decent didactics, decent peds, and Manhattan in a very liveable way. For me the tough part that put them lower is the discord amongst the residents right now. The new surgeons from Sinai have increased the work-load for the residents, which I'm now averse to, but it's also increased the unpredictability. For me that was the most important part, and what I believe has caused so much strife for the residents at this point. While research opportunities are important to me, and Cornell doesn't have the set up of the four for me to go in the direction I'm looking at, I probably would have ranked them one or two if it weren't for these issues. The crux is that the PD, Swamidoss, is fantastic, seems to be a great resident advocate, and is actively working to correct this situation. Signing up to be there in a year's time with the likelyhood that things might not improve, or might get worse just seems like a gamble to me. A frustratingly difficult fourth.
My decisions are all based on the impressions I've garnered over the past few months. If you've got any additional or different information, I'd be happy to hear it. . . might make the final decision easier.
