And the savings opportunities being missed, in the Washington Post:
Defensive medicine -- the practice of ordering tests and procedures that aren't needed to protect a doctor from the remote possibility of a lawsuit -- is ubiquitous. A 2005 survey in the Journal of the American Medical Association related that 93 percent of high-risk specialists in Pennsylvania admitted to the practice, and 83 percent of Massachusetts physicians did the same in a 2008 survey. The same Massachusetts survey showed that 25 percent of all imaging tests were ordered for defensive purposes, and 28 percent and 38 percent, respectively, of those surveyed admitted reducing the number of high-risk patients they saw and limiting the number of high-risk procedures or services they performed.
Trial lawyers have lately seized on evidence that tests can be overused for other reasons as well as an support for the view that the role of defensive medicine can safely be ignored. Glad they've cleared that up!
