Let me know if you recall more about the cite.

But maybe most treatment is optional or speculative. If so, maybe we could spend 1/3 what we do now and be just as healthy.

Sure we are lots healthier now than in the past. The question is how much credit medicine deserves for that. Lots of other things have changed besides medicine.

It is a random sample of all Medicare patients. It looks at 5000 hospital regions in the country, and predicts total mortality in each region from a long list of features, one of which is how much is spent there in the last six months of life. I gave the URL for it - take a look for yourself: http://nberws.nber.org/papers/W6513
