Romania has universal healthcare, if pathetic, and health care data is likely not stored at all, and in any case not at a centralized place. And we're definitely in Europe, the EU even.

Admittedly, this may be a bit besides the point. Still, I think the universality of your assertion is based mostly on thinking that the world is made only of a handful of "important" countries.

A lot of UK NHS patient data is stored by GPs who are private sector contractors and do not use NHS systems.

I do not know the details - I have worked with medical systems handling NHS data a bit but not the details of what is stored where and how it is transferred between systems. I do recall some news stories about GPs not cooperating with the NHSs push to a centralised system because of privacy concerns - articles on The Register IIRC.
