Different patients need differing amount of times. We're not talking about doctors who work in private practice and have business hours. We're talking about doctors who work in hospitals and work prearranged shifts and have on-call time.

A doctor can't necessarily predict how much time a patient will need. If a doc is on an 8-hour shift (hypothetical; I doubt any docs are so lucky!), and gets a new patient at the 6 hour mark, it might not be known if the patient will only be in the hospital for an hour, which would be fine, or 4 hours, which would push the doc to 10 hours.

As the argument goes, that patient is safer staying with the doc into his/her 10th hour on the job, versus being transferred to a different, fresher doctor midway through. I think there's enough truth there for it to be persuasive, but 1) there are limits to how effective a doctor is going to be after a certain amount of time, and the benefits of patient continuity must start dropping as the doctor has been working longer, and 2) there seems to be little attention paid to improving the process of handing a patient off between two doctors, which could further reduce problems related to lack of continuity to the point where a doctor who has been working 10 hours will cause more bad outcomes than shifting patients to fresher doctors would.

But that's a big part of the problem already. It shouldn't be luck to have an 8 hour shift, it should be standard. And of course there may be times when circumstances demand you deviate from that standard, but if you start with 12 hour shifts, you already start wrong, and it can only get worse.

I think we're deviating from the point I was trying to address. The length of the shift isn't relevant, what's relevant is that different patients need different amount of times, and can arrive at any time during a doctor's shift. Based on both of those variables, a single patient can easily require care beyond a single doctor's shift, so saying "getting done with your current patient and then leaving should never lead to a 12-hour shift" doesn't really make sense, since that "current patient" could have arrived during hour 6 of your shift and then required a 6 hours of attention before being discharged. If you believe that doctor-patient continuity is more important than a doctor's rest, then you can easily justify any shift length up to the point where the doctor falls over.
