According to the Institute of Medicine's publication in JAMA in July of 2013, the US is falling behind most industrialized countries in nearly every measure of health care even though it is generally improving in most areas including an increase in longevity by three years.
This has little to do with how much we spend on health care because we spend more than twice as much as most other countries that are ranked in front of us. We also do not focus on a healthy lifestyle. The top risk factors increasing our risk for chronic diseases includes, poor diet, smoking, obesity, and hypertension. The most common causes of death have also not changed -- heart disease, cancer, stroke, diabetes, etc.
