The health costs of defensive medicine

By Walter Olson, Ted Frank, and David Nieporent

There is no shortage of examples of medical malpractice litigation where plaintiffs blame doctors for failing to perform a CT scan. E.g., Oct. 2006 and Feb. 2004. This plainly raises costs far more than the direct costs of medical malpractice insurance that you see when the trial bar claims that malpractice reflects only 1-2% of health-care expenses. Tom Baker, among others, argues that defensive medicine has to be viewed as good with bad, because of improved health-care outcomes from the additional care. But not all defensive medicine is positive; it can be irrelevant, or, worse, adversely affects health results.

Malpractice litigation does change doctors' incentives, but only with respect to short-term results. Because doctors won't be sued for long-term consequences of defensive medicine, there is a substantial risk of overexposure to radiation in the course of defensive CT scans—a problem identified in a study in the latest issue of Annals of Emergency Medicine (Winslow, et al., Quantitative Assessment of Diagnostic Radiation Doses in Adult Blunt Trauma Patients; Reuters summary), finding that standard trauma treatment—1005 chest X-ray equivalents—results in an additional 322 cases of cancer per 100,000 treated because of use of CT scans. Earlier: Feb. 2004.
