From preventive policy to preventive practice.

Characteristics of the relationship of preventive policy to preventive practice are reviewed. The relatively low emphasis on prevention compared with treatment programs is discussed and the particular problem of the "anonymity" of prevention is defined. Prevention programs suffer in part because of the lack of identity of the specific individuals benefited. Examples from the cardiovascular diseases are used to illustrate the general points. The contrast between community- and patient-oriented prevention is important. Adequate levels of disease prevention and health promotion will never be attained one case at a time. Interactions among individuals are determinants of environmental behavioral factors relevant to health. The policy forming process is intrinsically interactive in nature. The Institute of Medicine's 1988 study of the future of public health is reviewed with respect to its emphasis on professional participation in the health policy process. Prevention is an essentially multidisciplinary area requiring the participation of many professions and disciplines. This property of prevention will be enhanced in the future. Ten principles which can be useful in translating preventive policy into preventive practice are presented.
