In the 2000 survey, Switzerland spent the most per-capita of all European countries, US $3,216, compared to the US spending at US $4,631. By GDP, in 2000 the US spent 13.2% of GDP on healthcare, while Switzerland spent 10.3%. In the 2005 survey the US spent 15.4% of GDP while Switzerland spent 11.4%.
Wait times and quality of treatment are considered to be similar or slightly better than in the US.
I find comparing the Swiss system to the US to be interesting because they just recently (1997) moved from a system very much like what the US had to a system relying on non-government insurance coverage, with mandated coverage for all. The government specifies the basic services to be covered, and what a basic policy must look like in terms of copay, deductible, and maximum out of pocket. Any company offering insurance has to offer a policy meeting those standards, but may also offer other policies, with different deductibles, additional covered services, etc.
They don't have the morass of government healthcare plans (Medicare/Medicaid/TRICARE/SCHIP, etc), instead providing a simple subsidy for those who could not otherwise afford coverage to bring the cost below about 10% of income.
The insurers have a guaranteed market, in exchange for meeting regulatory requirements on plans that they offer.
