Spain. I have private health insurance (it’s quite affordable here).

If you are dying, use the public services. They will do whatever it takes (under their material resources) to save you.

If you want comfort and probably reduce waiting times, go private. Public hospitals have long waits for anything that’s not immediately disabling/life threatening.

Example. My dad had a fall at home alone and broke his femur. He used his telemedicine device to call for help. When I got at his home, the paramedics were already there. They stabilised him, put him in ambulance and brought him to a public hospital. The same evening he had a titanium inserted. After five days in the hospital he was transferred to a recovery center.

Guess the cost?

Zero euros.
