Ahh, beg to differ --- yes, the specified curriculum is the same but how the specifications are met are as vast and varied as the human mind can conceive ---
So things to consider:
1) Do you like the area? Can you find reasonable housing close by (important on post call days and home call) in a neighborhood you would feel safe/want to live in
2) Do the residents seem happy? Can you talk to all of them or do they have some that they hide on "off service" rotations that never seem to be available when you're there?
3) How many procedures do the residents actually get -- ask to the see the procedure logs of more than 1 resident -- see if you can observe a few biopsies (both shave and punch), joint injections, OB procedures (cryo, implanon) that THE RESIDENTS are doing unsupervised (means they've been signed off) -- also check to see if they can let you observe hospital procedures that THE RESIDENTS are doing unsupervised, including central lines, paradentesis/thoracentesis, ABGs, etc.; suturing, stapling, treating shoulder dislocations, setting fractures, casting/splinting/wound treatment/starting IVs
4) Look at how freely the residents ask questions, especially the interns -- check the interactions with the attendings -- do the residents seem comfortable, do they call them by their first name?
5) Ask if they've put a resident on probation? how do they handle problem children? what's their plan for a resident who's struggling? How often in the last 4-5 years have they had a resident not graduate? Transfer? What's their coaching process?
6) if they're opposed -- how are they treated by the specialists -- go rotate with some of the residents who are on off-service rotations and see how they're treated?
that should do it for a start
