One way that Bismarck nations control costs is through government-set prices for care.

Patients in France typically pay all their health fees directly to the doctor and are later reimbursed by their insurance fund.

People in Bismarck countries tend to visit the doctor and receive more CT and MRI scans than people who live in Beveridge countries.
