I can only n=1, but most, if not all, experiences we've had obtaining medical care were better in Europe. Care specialist for my autistic kids, primary care, etc. From my unofficial surveys, many folks I know in the US are having a hard time finding various care providers, even if they have insurance. More data on this is always welcome.
I can believe this; it's my personal and anecdotal evidence (and that which is believed by family) that the maximum quality of US medical care is quite incredible, but any perceived median (accounting for accessibility and cost) is really quite shit
It seems fairly common in the US to have a hard time finding a doctor that will take your insurance, especially so if you are on Medicaid. Even with good insurance, a lot are just not seeing new patients. More and more tasks are being pushed off onto nurse practitioners and physician's assistants. And the number of residencies is still limited by the AMA, so you aren't getting enough new doctors.
