Surgeries On Friday Are More Frequently Fatal

antdude writes "A British Medical Journal (BMJ) research report says that 'Surgeries on Friday Are More Frequently Fatal ... compared to those who opt for really bad Mondays, Britons who have a planned surgery on a Friday are 44 percent more likely to die. And the few patients who had a leisurely weekend surgery saw that number jump to 82 percent. The skeleton staff working on weekends might be to blame.'"

The study only looked at elective surgery, not urgent surgery.

If you want real stats you have to go procedure by procedure and compare similar cases

Which, amazingly, is exactly what the authors of the paper did. It's open-access; click the link and read it for yourself.

Oh, wait, I forgot. On Slashdot, scientists are morons and people who read an article on a pop-sci site a month ago know everything, and any use of statistics can and must instantly be banished with the Words Of Power, Which I Will Not Utter Here.

This study is only about scheduled surgeries, i.e. non-emergency surgeries. That said, there is a continuum between the two, so it is plausible that they're more likely to be somewhat urgent, or else they would have put them off until a few weeks later so the doctor could go play golf. :-D

That said, I think the fatigue theory has a lot of merit. It is common knowledge that surgeries performed later in the day have higher rates of complications, surgical errors, anesthesia mistakes, etc. There's no reason to believe that surgeries later in the week would not be similarly affected, for precisely the same reason.
