My own experience with our health system occurred a couple of years ago. I paid $750/month for health insurance for myself, which was the full cost since I owned the company. I had a very minor stroke while photographing a friend's wedding in Bellevue WA. Within 30-40 minutes I was in the emergency room where I told them I had suffered a stroke that caused partial blindness. They concluded that I might have a detached retina instead and that I should return to PA and visit with my normal doctor. No treatment was done and I was not seen by a neurologist or ophthalmologist.
I flew home the next day where it was determined quickly that I had suffered a stroke. Because I was not treated in the ER, my partial blindness became permanent while clot breaking treatment at that time would almost certainly have restored my vision. I spent three days in the hospital for testing. A couple of months later I had a prostate biopsy whch created enough swelling that I ended up in the emergency room for catheterization. My medical bills for the year were over $60,000 of which I ended up paying almost $5,000 out of pocket. Much of the care I received was great, but not where it counted most. The cost, whether paid by me or the insurance company (from an economic perspective it's the same) was at best questionable.
I believe we have a very good health care system for those that can afford to pay and a very poor system for those that cannot. As Hoosier indicated, some of our poor outcomes on health indicators says more about our diet than our health care. However, that is less valid when dealing with meausres of infant mortality where we do not look good compared to most of the developed countries and many of the third world countries. In those cases, poor distribution of services is more of a factor.
