CCF isn't really an academic program in the traditional sense of it. The CC is a money making machine, and they do manage to snag some decent talent and get some research done in-spite of this. They have good name recognition with the lay person. They have the reputation that they - the people running the place - are there for the CC first everything else come second, and if you happen to get a deec education out of doing their staff's h&p's and consults, then bonus for you and I suppose them. They have really sick patients in their ICUs which is kind of a good thing as long as it's not overwhelming. I just don't take them that seriously. Maybe it's because I'm an ivory tower snob (I'm not), but I just don't think it all adds up to some kind of great career builder on the aggregate. If you're planning on going out into the community to practice, which is fine, that's where MOST docs go and the community needs good docs, then CCF would be fine at the top of your list. If you're at all serious about doing REAL research, making a career out of that, then it's not a place at the top of your list.
Rank the programs the way you want to rank them. It's your fellowship and your career. You know your goals. Going with your gut has almost never done anyone wrong.
