Have a read of this - the Commonwealth Fund rankings of wealthy country's health care systems, published last July:

http://www.commonwealthfund.org/publications/fund-reports/20...

Just to add some colour:

Quality: U.S. fares best on provision and receipt of preventive and patient-centered care. While there has been some improvement in recent years, lower scores on safe and coordinated care pull the overall U.S. quality score down

Access: Not surprisingly—given the absence of universal coverage—people in the U.S. go without needed health care because of cost

Efficiency: On indicators of efficiency, the U.S. ranks last among the 11 countries

Equity: The U.S. ranks a clear last on measures of equity.

Healthy lives: The U.S. ranks last overall with poor scores on all three indicators
