There are mountains of research comparing US healthcare cost-effectiveness with that of other countries, done by everyone from the OECD to McKinsey. The broad consensus is that, over all, the US system is far less cost effective than that of most Western countries, Japan, and a number of others. I recall that Berkshire, Amazon, and JPMorgan banded together to tackle this behemoth problem … and soon thereafter gave up.
The big cost drivers in the US system include high admin costs (paperwork, admin staffing), a large for-profit element that’s driven by billing for volume of procedures rather than for outcomes, and high pharma costs (incl. outsized advertising expense). The system also devotes an inordinately large fraction of total spend on expensive procedures on elderly patients that add little if anything to their quality of life (as noted in a prior post). The situation is hardly helped by the fact that the US has among the highest number of hospitalizations from preventable causes and the highest rate of avoidable deaths (esp. firearms).
The US “system” is in reality 3 systems cobbled together and largely an accident of history (as noted previously). For folks with great insurance and drug coverage (like me), it’s arguably the best system in the world, esp. if one requires state of the art care. For most of the year, I live walking distance from a world-class university medical center from which I receive excellent care (including twice for life-threatening medical issues) at very little cost (to me).
For most folks post-Obamacare, the US system offers decent health care but at an unnecessarily high price. Other systems worldwide provide better care at less cost: they eliminate much of the overhead, most or all of the profit skim, and keep costs within an overall annual budget.
As for the under-insured and uninsured in the US (about 1/8 of the population), they get little regular preventive care and show up in the ER when they’re very sick or badly injured. They’ll have bills trailing them for many years, much of which they’ll never pay off.
