Actually, it really isn’t.
It’s about connection. Before I got admitted for to any hospital, my family asked around all their friend on who knows anyone important in a hospital.
We went with a hospital where we knew the chief of medicine even though its a much smaller hospital than some.
The head of department came and did my admission and did the surgery himself. We of course sent nice gifts (bribes) to everyone involved.
Thats the only way you will get decent treatment in any hospital around here.
