The best approach is to find a couple programs you really like and do away rotations there and do well. Here is my take on some of them after interviewing/knowing people there/doing aways.
Philadelphia hospitals: I hope you like trauma.
Jefferson: Really good overall general surgery program. I loved the residents I worked with there and the surgeons were very very good. I found the program's hierarchy rather malignant though. Residents worked long hours (100+ two weeks I was there, 80+ the other two). Not as trauma heavy as Penn/Temple. Require 1 research year (6-yr program), may become 7yr depending on when you apply.
UPenn/HUP: Will see great surgery. reputed to be malignant. I was there as a student and found the people I worked with liked me (do your job, do it well, don't complain) but people could be really short/blunt. Research heavy. Attendings very good at what they do. Adherence to hours questionable. 7 year program (two research years)
Temple: Very trauma heavy because you are in the heart of ghetto. Will see a lot of gsw/stabbings. Not so fantabulous for things like whipples, hepatobiliary, transplant surgeries, but you'll get more than your fair share of numbers and it will be exciting to say the least. They try to adhere strictly to 80 hr wks (the residency director is awesome with residents). (5 year program)
Drexel/Hahnemann: Less trauma heavy. Short staffed. Longer than normal hours. Not reputed to be the best program mostly due to financial instability of the institution. (5 year program)
Abington (PA): Great program. One of my friends is here and he loves it. It's a private hospital, but the attendings let the residents work will all their patients. Very focused on teaching. (not good for research if you want to do it). Adher to 80 wks on average (they try to make it a point). Will def. get numbers. (5 year program)
UMDNJ: Good program. Residents I know from there noted that they get good numbers, not really malignant, lots of experiences. Do less scut, better hours. (5 year program)
Problem with phila/camden hospitals: you do a lot of scut. Nursing help isn't as nice as other places or private hospitals, because they are very very short staffed. As a student, I did about 100 abg's alone in three weeks (I was only one doing them in the ICU), A-lines, IVs, dressing changes, etc. Social workers are limited in the area too. But you learn a lot and it prepares you very well, although as an attending, you'll probably very rarely need to put in an IV.
Hope this helps
