One versus two fellows programS. I think that is a tough one. I know people who have gone to programs with only one fellow and have loved it (mayo in Jax, the one that I have heard the greatest things about). That being said, with one fellow programs I am concerned flexibility may be an issue. For example, if you want to change vacations or go to a meeting, changing your schedule may be a little bit more complicated with 1 fellow versus 2-5 fellows. Another thing that concerns me would be the on call schedule. However, I have to say the amount of fellows per program does not necessarily correlate with the number of weeks on call per year. I know of one big program, with more than three fellows per year, where fellows are on call for 26 weeks, that is half of the year. My understanding is that the program covers several hospitals. My recommendation is that you should go to every program you get an invite from. Your personal impression is the most important thing when choosing a place to do your fellowship. If your application is not superstrong and you really want to match, you should apply to one fellow programs. You never know what it will be like!
