Last February, the New England Journal of Medicine ran a potentially misleading review of the cost-effectiveness of illness prevention strategies that may have led many casual readers (such as the editors of the Washington Post Health section) to conclude that most health-improving measures — such as aggressive counseling for people who are either overweight or smoke — cost more in the long run than they are worth. This week’s Journal of the American Medical Association carried a proper antidote by Steven H. Woolf of Virginia Commonwealth University, who is fast becoming a leading expert on prevention techniques for improving the nation’s health.
Woolf admits that personal behavior is difficult to change, and many intervention strategies for preventing disease cost more money for the health care system than they save. But he takes direct aim at the NEJM article claim that "drew similarities between the cost-effectiveness ratios of prevention and disease treatments, all but ignoring the much lower cost-effectiveness ratios of the preventive services that guidelines advocate."
