Sorry, I only have my personal experience and that of my family and friends. And I didn't say "low".
Usually it's highly bureaucratic - you have to "climb a ladder" of doctors. First your GP, then a specialist, then, maybe a hospital. You wait a lot (sometimes weeks and months, because you are not "emergency"). And sometimes you encounter outright incompetence and have to go to a private doctor/hospital to have your problems properly attended to.
That summarizes my experiences with the healthcare systems of 4 different EU countries.
