The necessity of understanding and aggressively arguing for your medical care is a real shame here in the US and IMO most of the reason why we see worse outcomes for certain minority groups with heart attacks etc not getting sent to specialists at the same rate. My experience is some doctors and staff actively welcome you participating but some don’t and you never know which one it is.
Living outside of the US, advocating for your own care is actually good. When I lived in Asia you generally don’t question what your doctor says, you just do it.
Thats certainly true in my experience in Japan, though there they are usually hyper conscious of doing procedures correctly so I don’t know if it would be better or worse.
