actually, i found that most of my programs had traditional call during intern year at least. about 33% had night float during 2-3 or 4 years. i cannot think of one that was night float all the way through. this surprised me. personally, i could have gone either way. i like the shift work of night float, and the fact that when not floating, you go home at night. but, traditional call is cool too, as you go home the next day by noon. and, with the 80 hour rule, it seems like 6 in one, half dozen the other. in most programs you will get near 80 hours a week on some months, and get 50-60 on others. i didn't notice a big difference overall in the time spent working.
