In many places in Europe, they have a so-called “treatment guarantee,” which means that if the wait is longer than 30 days for non-emergency treatment and procedures referred by a doctor, you can elect treatment at the private hospital instead of a public hospital. No charge.
For emergencies, you are always treated immediately at either a public or private hospital.
E: I’m mentioning this because I’ve encountered a large number of uninformed Americans who always start crying about “people dying on wait-lists in Europe and Canada unlike in America.” No.
