This document discusses adolescent use of preventive services based on USPSTF recommendations and an analysis of claims data from a large health plan. The analysis found that the rate of preventive care visits was low, averaging less than 0.3 visits per year. Adolescents had more frequent non-preventive visits, averaging 1.5 visits per year. Longitudinal data on over 40,000 continuously enrolled adolescents showed that guidelines for annual preventive visits were met less than 2% of the time. The document recommends developing better evidence for adolescent clinical preventive services, taking advantage of every medical encounter to provide preventive care, and using clinical systems to improve delivery rates.
