Outliers do not say much about the overall quality of healthcare in a country. Rather obvious lesson in statistics.
Reminds me of the Russian mathematician who moved to the US after the fall of the Soviet Union. Most of his essays were criticizing American students, but in one essay he was quite frank:
Russians who graduate with math degrees are better than Americans who do so, by a wide margin. However, the average American is better at math because they still get access to some math education in university and do not need to be a top student for admission. Whereas in Russia, if you didn't meet a rather high bar, you simply couldn't get admitted as an engineering/physics/math program, and thus couldn't further your math education (I believe he said the cutoff was even before university).
Country with the top mathematicians, but country with worse math outcomes.
