#2Almost certainly the selection bias plays a major role - surgeries done early in a week are different than those scheduled later in the week.

#3What about during football season? Doctors and nurses are pretty serious folks, but I can see them having a few too many during the exciting football games. Not all of them, of course, but some like the games.

Yeah, this reminds me a lot of the "Impossibly Hungry Judges" problem[0].

That's certainly a possible confounding factor that should be investigated, but let's not jump to conclusions.
Jumping to the conclusion that Monday surgeries are simpler could hide an important phenomena if that's not the reason Monday surgeries have lower 30 day mortality rates.

They do take this into account in the text. Odds ratios imply less risky procedures were normally done on weekends anyway, and you see the effect on all days other than Monday (to a lesser extent).

#8A mortality rate of 0.7% for elective procedures sounds high. What counts as elective but carries such risk? Is it similar in other countries?

This is a great article. The original paper was in my head as a truth, and I've revised that since reading this post. Thanks!
