Fellows do not take at-home or pager calls. In addition to Monday through Friday daytime shifts, fellows also work during the day on 2 weekends during the months when they are rotating on pulmonary consults. While rotating in the ICU at CPMC, fellows work a block of four consecutive nights in lieu of a 7-day week of daytime shifts. During all other rotations, fellows work during the day on 1 weekend of the month.
