The Czech Republic, it's even worse in Poland, Hungary and Slovakia (personal experience); I also have even more horror stories about the Czech system - right now I'm waiting for the third month to finally get a bad tooth checked (and I will have to pay around $500 if I don't want the tooth simply extracted, no other option covered by insurance is available).
On the other hand I had extremely good experience with cheap private healthcare in Ukraine. I wasn't brave enough to test their public system.
Sorry I didn't mention it, I thought I did but I mentioned just the currency.
I'm not denying that certain public systems work good or even great - there is Germany just next to my country with their excellent system (it's getting worse according to my German friends though, but I'm not sure about that, I don't have enough first-hand experience). I'm arguing that there is less motivation in a public system so it could easily lead to bad situations, but of course sometimes it doesn't.
