Many of the worlds best hospitals are in Europe, in countries like Denmark, Germany, Sweden, France and Sweden. Just as one example, Charité in Berlin is world famous and have had "more than half of all German Nobel Prize winners in Physiology or Medicine" (https://www.charite.de/en/), just as one example.
Granted, many of the best hospitals are indeed in the US, but I guess less people have access to the many great hospitals in the US (or can afford access rather) compared to hospitals in Europe.
The main difference between Europe and the US on this point is health insurance (or the lack of in the US). Those technologies are available worldwide - it heavily depends on whether you can afford it or not.
