Here are some thoughts on the IM programs people seem to be asking for:
1) UCLA: excellent program; but hard. Its for those people who are basic science oriented. Housestaff have very little voice in changing things. They get top notch applicants (i hear this year, its over 2000 applications for their IM program! .. yikes, who's got a calc to do the odds?)
2) Harbor-UCLA: Another excellent program. Academically upthere with UCLA, great patient population; however, the housestaff are scutted like you would not believe! call months are too rough and back-to-back.
3) Cedars-sinai: Excellent faculty, not quite competitive against UCLA or Harbor. Good housestaff, but given that the patient population is predominately private, you only get to really touch 1 out of 5 of your patients, the other 4 are looked after by the attending, and you're no more than a glorified shadow.
4) Olive View- UCLA (aka SFVP): Excellent teaching/academics, strong housestaff, incredible patient population/pathology. You get to be the real doctor here, no scutwork, and a fair workload. Housestaff are the happiest here.
My personal feeling is that they're all great programs, and you will learn a lot; but depending on your personality type, I would chose accordingly. Hope it's useful, good luck on apps!
peace,
