In this morning’s Richmond Times Charles Krauthammer rails against the use of preventive interventions based on cost effectiveness in reducing chronic diseases. His argument is based on a CBO study but he lacks knowledge of epidemiology and appropriate interventions. At the same time we hear about a new report in the Journal of the National Cancer Institute (2009, August 18) that the public overestimates the value of screening. The authors found that the majority of participants have a dramatic overestimation of the benefits of such tests, and that doctors and other sources of information appear to have little impact on improving knowledge of the level of benefit. Ninety-two percent of women overestimated the benefit of mammography screening by at least one order of magnitude or reported they did not know; 89% of men overestimated the benefit of prostate-specific antigen screening or did not know. "Knowing the benefit of a treatment is a necessary condition for informed consent and rational decision making," the authors write.
