In 1984 the Assistant Secretary for Health formed the US Preventive Services Task Force (USPSTF), asking the members to develop age-, sex-, and other risk factor—specific recommendations concerning the appropriate use of preventive interventions in the clinical setting. The article by Greene et al1 in this issue completes the series of background articles and recommendations by the USPSTF published in JAMA. Since the April 1987 report on breast cancer screening,212 articles and an introductory editorial have been published in The Journal.1-13 These background articles were prepared by task force members for use in their deliberations and aided in the development of their final report, the Guide to Clinical Preventive Services: An Assessment of the Effectiveness of 169 Interventions.14
The guide provides recommendations for clinical practice on 169 interventions for the prevention of 60 target conditions. These interventions include screening tests, immunizations, chemoprophylaxis, and patient counseling.
