I find it extremely difficult to compare health care among industrialized countries.

Availability is also a factor in costs.
You often hear praise of the health system in Sweden, while a friend of mine said that she needed a while to get used to long waiting times before she would get an appointment.
So, in some countries people consider it normal to wait 2-3 weeks for a dentist appointment, or half a year for some heart surgery. In other countries both is a matter of hours or days.
Under some national health plans, the use of "fancy" technologies like MRT or PET scan/CT is reserved for the almost terminally ill, while elsewhere it's routine.

I find it really hard to make an overall judgement on what is "better" or "cheaper" unless you can also compare what you will get for you money, and how readily available it is.
