The best doctors in the US are more often than not also the best in the world. The US disproportionately attracts from abroad and produces domestically the MDs that are at the forefront of medicine.
The good and the okay doctors, i.e. the vast majority, are also very good. Probably a wash with most large Western nations.
America's actual problem, and failure, is prevention and uniform access to primary care. No surprises here.
Some US doctors are rich. With a strong bias toward certain medical specialties, where you can bill X thousand dollars for a "procedure". And do a lot of those procedures every week.
Vs. merely billing by the hour - then having to pay your office rent, utilities, medical school loans, nurse's salary, receptionist's wages, etc. etc. out of that. I've read quite a few accounts of that sort of doctor going bankrupt...unless they were being supported by the specialists, to whom they were referring patients who needed procedures or other expensive care.
Just anecdotal, but I visited Shanghai this summer and toured a top clinic - from my perspective, their standard of care is on par with, if not better, than many large (and quite good) groups like Sutter Health or Straub. The doctors there were educated in the U.S. and Germany (Massachusetts and Munich if memory serves).
Plus, if you can wait, treatment is nearly free, but you can get same day service for many procedures, like overnight ecg, for say $100 -$200.
Chinese public hospitals, at least ten years ago, didn’t provide nursing assistant care, so families would be responsible for cleaning and feeding someone in the hospital. Private hospitals are another matter, and when I lived in Beijing, I would go private even for ER services. And the private hospitals were pretty affordable, most of the doctors were foreign or foreign trained, most Chinese med students go to the public hospitals for residencies and after they graduate (my wife has a cousin in Shanghai finishing up her Med degree now). The program is different, it’s a 5 year degree plus residency, though you can go for a masters or PhD also (many doctors do), I think the American system of medical school is the odd one out.
Private health insurance had a cap (~$100k/year) for some reason. I thought that was risky.
If anyone has a friend or family member in the hospital, the best thing you can do is spend a few hours with them every day until they get out, or arange a schedule with other friends and family members.
Patients need advocates (and someone to help them from getting lonely, which also helps their recovery).
US doctors are not that good compared with a German or French doctor, they could be as bad as bad doctors in other countries.
