Here is another possible factor: poor quality care (no offense to dear Rich)

The report identifies the causes of poor-quality health care as underuse, overuse, misuse, and waste of medical services. It estimates that 30 percent of all direct health care outlays today are the result of poor-quality care. A 2004 report by the RAND Corporation reinforces this point, as it finds that American patients receive proper care only 54 percent of the time
Right on target, and no offense taken.
I have spent the academic part of my career in a field called evidence-based medicine which strives to standardize care according to the best evidence when available. It also uses serious decision analysis to help use the evidence most appropriately. It results in better outcomes and about 30% lower charges. But it's a little complicated and its teaching has not met with uniform success. Canada is ahead in that regard -- in fact, I got my initial training and teaching experience in the field at McMaster.
Almost invariably, when you find pockets of care where the recommended approach for a given disease varies widely from doctor to doctor, it is a) more expensive, and b) not "evidence-based" in the formal sense of the term. Not only do we need better science, but we also need better systems to assure that we make the best of the science we already have.
BTW, I'd emphasize a point already made: we do have good and even great treatments and tests available that simply didn't exist 10 years ago. I am sometimes amazed at some of the new technology. But the chaotic market, regulatory, intellectual property and other forces invariably cause new technology prices to the very top edge of what the market will bare.
Sometimes I wonder if the only solution that will tame all this is a "clean slate." The forces at play are very highly entrenched and it is not easy to just practice good, compassionate, and scientific medicine in the community. Here in the academic towers there is some shelt
