Overall, I'd agree. For the most common ailments that people would routinely see a doctor for or need and ER for, the "value for the hassle" is quite low.
For specific facets, we actually do really well (for instance, 5-year survival rates for certain types of cancer, and having the latest and greatest technology for certain cardiac medical care)
Granted, you have to live in close proximity to where those specialized services are offered. I'm fortunate enough to live in Northeast Ohio. Where (and I don't know the reason this came to be for a city like Cleveland) we have 3 globally ranked hospital systems with expansive networks all throughout the area, and their processes are quite streamlined. No matter where you live in Northeast Ohio, you can be to a Cleveland Clinic facility pretty quickly.
I've heard the dynamic described as "If you've broken your ankle, have a sinus infection, need your gall bladder removed, or just need a routine check-up, you're better of in a single-payer country...if you need heart surgery or cancer treatment, you want to be in the US (provided you have insurance) to have the best chance of survival"
Which, ironically enough, given the poor nutrition habits, the need for things like heart disease treatment and cancer treatment are higher here in the US.
