I'm not going to get into this debate here, I'd suggest checking out some info and then seeing if it fits with your assumptions. Page 200 here ranks worth health systems:
I don't think that table means what you think it means.
Table 10 on page 200 measures "attainment", which is something along the lines of (actual health improvements due to health care) / (best possible health improvements given spending level). That's a very different quantity than quality of care, which is what the original poster was talking about.
(It's actually more complicated, education levels are somehow worked in and details are described elsewhere.)
Rankings and indices are great, but it helps to know what you are actually ranking.
