When I did surgery, we were on q3d calls and when on-call, we stayed until 1-2am and therefore could sneak in 3 hours of sleep here and there. BUT our interns were like, "that's nothing! WHEN we were med students @ UT-Houston or Tulane (or fill in other names), we were on q3d call on surgery and we had to stay overnight with the residents!" So which schools are famous for being tough (or malignant) in its demand for students on clinical rotations? And which schools baby its students on rotations and are known to treat them insanely well? (cough, cough, UPenn, anybody? The intern from Penn sends my classmates home real early when they are on call together! Apparently, at Penn, they are only on-call q7d while on surgery and get one day off per week to sleep, GUARANTEED!).
