BACKGROUND • Majority of adolescent morbidity/ mortality is preventable
MORBIDITY/MORTALITY • Accidents and injuries leading cause of death for both males and females • Many of these accidents involve alcohol and other substances
MORBIDITY/MORTALITY • Sexually transmitted diseases are common infectious diseases among adolescents • Among adolescents ages 15-19, pregnancy and childbirth are the leading causes of hospitalization
BACKGROUND • Risky behaviors co-occur • Behaviors responsible for leading causes of morbidity/mortality during adulthood are initiated during second decade of life (e.g., smoking, substance use, physical inactivity, risky sexual behavior)
PROMOTE ADOLESCENT HEALTH • Requires participation of • Adolescents • Families • Schools • Communities • Federal, state & community policies

ADOLESCENT CLINICAL GUIDELINES • National Committee for Quality Assurance (NCQA) Guidelines (HEDIS) have Adolescent-Specific Measures: • Screening for alcohol use • Annual visit to provider • Immunization status • Screening sexually active females for Chlamydia trachomatis (Over 15 years old)
ADOLESCENT CLINICAL GUIDELINES • Despite guidelines, current delivery of preventive services below recommended levels • Limited research on how to implement adolescent preventive services
RISK AREAS • Risky behaviors associated with major morbidity and mortality in adolescence: • Tobacco • Alcohol • Drugs • Sexual Behavior • Seatbelt • Helmet
SEXUAL BEHAVIOR • Increase condom use • Delay onset • SUBSTANCE USE • Decrease initiation • Decrease use • TOBACCO • Decrease initiation • Decrease smoking • SEATBELTS • Increase seatbelt use • HELMETS • Increase helmet use • SYSTEM IMPLEMENTATION OF PREVENTIVE SERVICES • Increased Screening • Increased Counseling INCREASE PREVENTIVE SERVICES TO ADOLESCENTS
GOAL • Develop and evaluate a system intervention to increase the delivery of adolescent clinical preventive services
SYSTEM INTERVENTION TO INCREASE DELIVERY OF CLINICAL PREVENTIVE SERVICES CURRENT DELIVERY OF PREVENTIVE SERVICES IMPROVED DELIVERY OF PREVENTIVE SERVICES Provider Training Tools Health Educator
TRAINING • 8-Hour Training for Pediatric Primary Care Providers • Adolescent Health and Development • Effective Communication with Adolescents • Give Clinicians Targeted Specific Messages about Risk Behaviors
TOOLS • Adolescent Health Screening Questionnaire • Provider Charting Form • Provides information from the Adolescent Health Screening Questionnaire to indicate health behavior of the patients • Provides prompts and cues for provider intervention
GUIDELINES FOR PROVIDER INTERVENTION • Not Engaging in Risky Behavior • Reinforce positive behaviors
GUIDELINES FOR PROVIDER INTERVENTION • Engaging in Risky Behavior • Confirm response • Express concern about risky behavior • Provide key messages

International Pregnancy and Birth Rates, Teens 15-19 The United States has much higher teen pregnancy and birth rates than other fully industrialized countries. U.S. teen pregnancy rates are twice as high as rates in Canada and eight times as high as rates in Japan. UNICEF. (2001). A league table of teenage births in rich nations. Innocenti Report Card, 3. Pregnancy rates were calculated by the National Campaign using birth and abortion data from this report and miscarriage data which were estimated using the formula the Alan Guttmacher Institute uses in generating U.S. teen pregnancy data, with miscarriages=20% of births + 10% of abortions.
