I definately concur with a lot of what gel1 said... here are some more general thoughts that I cut and pasted from an old PM I sent someone...
1. The approach in the 3rd and 4th years of treating med students like colleagues, and giving them a lot of freedom in the clinics and respecting their intelligence. Every 4th year I met talked about how different their experience has been from the typical scutwork stereotype. I think that by getting responsibility is the best way to learn.
2. Administrative support. Especially if you aren't going to school near your family, to have support from people who genuinely care (sylvia, lombard, rosita, the whole OME) just seems like such an advandage in dealing with the difficulties of med school, especially med school in a new city, new part of the country.
3. The approach the school takes to learning the delicate art of medicine. Things like Kyle the thanatologist, who is basically a death and dying coulselor in place solely for medical students. Dealing with issues all the way from anatomy lab (she teaches the short anatomy lab prep course about dealing with cadavers) to counselling 3rd and 4th year students doing their rotations. Every other school brushed over this topic, I'm sure they aren't disrespectful, but chicago seemed to stress the importance of it.
4. The 1st 2 years philosophy is to train you to think like a researcher and apply that critical mindset to a clinical setting. Most people say this makes the first 2 (especially MS2) really challenging, lots of material, I think P/F balances it out and I'd rather get more as opposed to less than enough material presented.
5. I'm interested in academic medicine, and while clearly I think most of the top schools can prepare you well for this, pritzker seems to place an added focus on this aspect of medicine. (can be a negative if you are interested in family practice)
anyways, as I said before I'm headed there next year, the link gel1 posted wasn't exactly a matchlist, they hand you one on the interview day. It has as many top hospital matches as any other (hopkins, duke, SF, stanford) I've seen. Pritzker can get you whereever you want to be, but a lot of schools can do that, so if you are lucky enough to get pick between places, go to where you want to be for four years. Pritzker is the best fit for me, I look forward to meeting all you guys next year.
