I've been interested, since the massive run of European deaths in the spring, why US case fatality rates are so much lower than most European nations. Even today, we're sitting at just under 3%, while almost all developed nations are higher.....and significantly higher.

I've been wondering if this is an area where having nationalized health care is an impediment to the evolution of treatment modalities. Put another way, does having a nationalized system (with nationalized modalities of treatment) discourage doctors from quickly evolving those modalities based on their own experiences? And is this one way that the US's patchwork system where hospitals essentially work independently from one another, taking advice from the CDC but not being required to follow that advice, works to the advantage of the patient, since doctors and hospitals are more free to evolve modalities based on experience?
