Noting that managed care organizations face numerous challenges as they respond to adolescents' special health care needs, this report provides the managed care industry with practical information about opportunities for strengthening their health care delivery to adolescents. The report is organized around two goals for health plans. The first goal, facilitate adolescents' access to health care, focuses on policies and systems that can enhance health plans' responsiveness to adolescent members. The second goal, engage teens, parents, and community resources to improve adolescent health, demonstrates the benefits of partnerships to maximize the internal efforts of health plans. The report contains 11 strategies that can help health plans reach these goals. Strategies for Goal 1 include promoting regular preventive health visits; seizing health promotion opportunities; ensuring access to primary caregivers with skills, experiences, and interest in adolescent issues; encouraging the use of multidisciplinary clinical teams; offering comprehensive screening and response for high-risk behaviors; protecting teens' confidentiality; and providing services through specialized adolescent health care centers. Strategies for Goal 2 are to: include adolescents in quality improvement initiatives, help parents and others learn how to support adolescents' health and well-being, participate in community-based health initiatives, and support and disseminate research about adolescent preventive care. Each strategy section also spotlights one or more existing programs and presents outcome data when available. Five appendices include the Managed Care Self-Assessment Tool, clinical preventive service guidelines for adolescents, the Group Health Cooperative parent/teen letter, acknowledgements, and program contacts and other resources.
