PSA Screening and Prostate Cancer


Making health policy involves many different aspects of life:  scientific evidence of a highly predictive diagnostic test, reasonable price, competing resource demands, comfort and convenience of a test, seriousness of the disease being detected, impact of the disease on the individual and the population, etc.

Anyone who’s been involved in health policy debates will recognize that, except for predictive value of the test and actual cost of the test, both of which can be determined somewhat objectively, all of the rest of the items listed above are laden with values (and one can argue even arriving at the predictive value involved significant calls on various values in doing the studies).   Evidence-based medicine only provides information, it doesn’t provide a support of values and how they will be applied in society.

Rather than reproduce some of the less-than-obvious arguments about screening for prostate cancer here, those interested can find more information in Paul Menzel’s and my recent posting on the Oxford University Press blog website.
