Frankly, as an American, I think we have shit quality of health service, based on the insurance cos' red tape and restrictions and paperwork alone. Getting healthcare in this country is a bureaucratic nightmare. Maybe the docs and meds and tests are good, but the overall service is bad.
(Disclaimer that I insist on Kaiser, an HMO – I would not live in a US area without it – which is pretty good, but helping family through health issues who had "gold standard" normal PPO was... different).
