I did a month there, so I can answer questions. The staff are all nice people, easy to work with. Good diversity and interests, too. There is a bit of a competitive air with Pitt, but at high levels everyone gets along, and we even had combined grand rounds one day. I got the impression that if you train here, you'd be ok anywhere, but if you're hardcore into research, then Pitt might be stronger.
The residents seem happy with most rotations, but PICU (at Children's of Pittsburgh) is a rotation that seems to leave a bad taste in their mouths. They work you pretty hard in some of the off service rotations, but it's getting better with the 80 hour requirement. One resident got like 5 days extra off at the end of the Neuro month, so she could stay under 80 average. You get a lot of ICU exposure, I think it was 6 months with CCU, MICU, Trauma ICU, Neuro ICU, etc. Makes for a busy residency, but confident residents who have NO problems with procedures. EM does airway. Teaching is protected time, and all on one day for the most part, plus M+M's and Rosen Rounds.
As for EMS, there's tons of opportunity for ridealongs on ground or air. LifeFlight just celebrated 25 years, so it's a well established program with 5-6 choppers. Dr. PS Martin heads it up, and is VERY proud of it.
I liked Allegheny, so let me know if you have any more questions. I'd like to hear what other people think about it compared to other smaller programs, so just keep this thread going...
