I'm not aware of a single example of an OECD state (the USA aside, obviously) that doesn't apply significant price controls on healthcare, either explicitly, or by imposing a state-controlled monopsony. Across all the various approaches to healthcare systems in the developed world, that seems to be the single most consistently-adopted measure for keeping healthcare costs from going crazy, as far as I can tell.
