I just came across, belatedly, a very interesting June 1, 2009 New Yorker article, "The Cost Conundrum", on the sources of greatly increasing medical costs (which confirm my own personal experiences).
Also very useful (I don't recall if I have circulated this before) with respect to medical errors, liability, and costs is a collection of articles in the September 2010 issue of Health Affairs magazine on the topic of "Medical Malpractice and Errors".
