The reason resident physicians work so much is because residents make $60k working 80+ hour weeks, and the PAs or NPs who would be willing to cover the floors at night would make $150k+ working 40hrs/wk. Residents also have no collective bargaining power because of the residency match system. You can't easily leave one program and go to another because you don't like the working conditions, for example. If you want to leave, you're more or less blackballed unless you're switching fields. And you don't want to speak up about the conditions because you've got $300k in debt and a degree that's useless until you finish residency.
The 3rd year of medical school is much tougher since we spend about 10 months of that year on rotations in the hospital. While some rotations are much lighter, others like surgery again get close to the hours limits. This is complicated by the shelf exams we take every 8–12 weeks. These require an additional ~2–3 hours/day of studying and most of a weekend day as well. Obviously, this study time is not counted towards the hours limits, but it definitely factors into fatigue and burn out.
Sounds like they should just legislate away the "Residency match system."
Pre-med = college, and aside from the highly scientific work load is no different than any other college experience.
Medical school (no longer called "pre-med" by anyone) is typically 2 years of classes and 2 years of clinical rotations. The rotations are not going to be 120 hours a week but may be 60-80. But unless you go to a teaching hospital and consent to student contact (which may or may not be a requirement of treatment) no med school student is touching you.
Residency is after med school (they're full doctors now) where you train your specialty, and at least in the 4 year program I'm familiar with, their title is intern, resident, resident, senior resident for each of the four years. They have increasingly high levels of responsibility as they progress and by the 4th year they are basically oversight/management of the other residents who assist on complex cases and bring in at attending physician(s) for big stuff. Hours are typically 80+ and I'm sure you could approach 100 for very demanding or emergent specialties but it's certainly not "pre-med training" and 120 is pushing it for sure.
After you graduate residency you move to an attending, fellowship, or research position and the hours drop back down to the 60-70 range and decrease as you gain seniority.
Can someone please tell me why they still put medical students through this institutional hazing?
