Preoperative Patient Frailty and Operative Stress and Postoperative Mortality

Isn't this pretty much accounted for by doctors at this point?

Isn't it well know that there's a good chance that an elderly patient will die during or soon after significant surgery? For instance, there's a good chance that soon former President Jimmy Carter will once again have a fall that will result in him being hospitalized, and shortly after surgery, he'll pass.

I think this is the paper that was written about in this NYTimes article. https://www.nytimes.com/2019/12/13/health/frail-elderly-surg...

"The findings suggest that even minor surgical procedures are associated with high risk for patients with frailty and that surgeons and referring physicians should consider whether the potential benefits of surgery warrant the increased risk."

TLDR: sick people die more when you cut them open, even for little cuts.
