Low-cost therapeutic agents. Uses and abuses.

The past quarter century has seen a transformation of the pharmaceutical industry from blind empiricism to the design of drugs to act as agonists or antagonists at specific receptor sites. As truly effective technology, many have led to marked savings in cost. Savings have been achieved when therapeutic drugs, often highly specific, can be substituted for surgery and other invasive procedures and when therapeutic drugs can be used to prevent illness and the need for treatment. Further savings are achieved with the reduced prescription of ineffective drugs. It is estimated that therapeutic drugs and vaccines contribute about half of medicine's contribution to increased life expectancy and improved quality of life in this century at about 7% of national expenditures for medical care in the United States.

Ivan Illich and the pursuit of health.

Fifty years ago, when medicine had relatively few effective treatments to offer, its value was unquestioned. Twenty-five years ago clinicians had become concerned that treatment could sometimes do harm and McKeown published epidemiological evidence claiming that medicine did little good. This state of affairs was used by Illich to bolster his crusade against technology in general. Today it is clear that medicine now makes a large contribution to health. But doubts still exist and alternative pathways to health are continually exhorted. Large-scale efforts at behavioural modification, encouraging the adoption of healthier lifestyles, have been largely unsuccessful. Social activists now argue that funds should be diverted from medical care to social programmes that, they claim, might contribute more to health. While it is true that health is strongly associated with socio-economic status (income, education and occupation), there is little sense of how best to reallocate scarce resources so as to improve the health impact of social and economic programmes. Social reform is not a substitute for medical care. Rather, our social environment is a second, important but quite separate, determinant of health and well-being.

Improving health: measuring effects of medical care.

The impact of medical care on the quality and length of life of the population has been poorly documented. The rapid growth of evidence of efficacy of therapy for individual medical conditions now offers the opportunity to create an inventory of benefits. A method for creating such an inventory is described, as is its application to a selection of condition-treatment pairs, chosen for their high incidence of prevalence, their serious outcomes, and the demonstrated efficacy of their treatment. An aggregate effect of medical care on life expectancy is found to be roughly five years during this century, with a further potential of two years. Although there is no overall index of quality of life analogous to life expectancy, our inventory demonstrates the enormous burden of pain, suffering, and dysfunction that afflicts the population for which medical care can provide a large measure of relief.

Is efficacy the gold standard for quality assessment?

"Efficacy"-medical care that is achievable under optimal conditions-is generally considered to be the appropriate standard for quality assurance. In this paper I argue that what is needed is a broadened definition of efficacy that includes the appropriateness of an intervention as well as the level of technical skill used in its provision. To establish efficacy, so defined, I suggest that well-designed nonexperimental, as well as experimental, studies be undertaken that employ registries and data banks, as well as formal clinical trials, and that decision analysis be used to synthesize the results. This will require a significant effort and investment in outcome studies of medical and surgical technologies. With growing recognition by the public that quality can be highly variable-aided by the Health Care Financing Administration's publication of hospital mortality and morbidity data-the medical care system will ignore outcome studies and quality assurance at its own peril.
