This study says: "Longer Shifts for Surgical Residents are Safe for Patients"

It does not say: "[Making residents work less hours for more money] ended in way worse patient care and more deaths. "

This study says: "resident physicians who were randomly assigned to schedules that eliminated extended shifts made more serious errors than resident physicians assigned to schedules with extended shifts, although the effect varied by site." However, it adds a big caveat: "The number of ICU patients cared for by each resident physician was higher during schedules that eliminated extended shifts." Additionally, the shorter shifts could still be 16 hours, and there was no data about total hours worked in a week, just about the length of a single shift.

It does not say: "[Making residents work less hours per week or for more money] ended in way worse patient care and more deaths. "

This study says: "Shorter duty hours for medical residents, although marginally better for residents themselves, may result in worse patient care, according to a randomized trial assessing resident duty hour schedules in the intensive care unit."

This is the closest to your argument, but again, it looks at the length of individual shifts, not total hours worked in a week or month, which may have more of an impact.

Until we see a few studies showing that sustained 40 hour workweeks with 8 hour work days are inferior in patient outcome, I think these are all just bullshit.

And even then, the issue is wellbeing of the residents. It's not all about the patients. My workplace does better if I work 100 hours a week; I do not.
