  1. The Effects of Receiving Adolescent Clinical Preventive Services on Adolescent Behavior Elizabeth M. Ozer, Ph.D. Division of Adolescent Medicine, Department of Pediatrics University of California, San Francisco Sixth Annual Child Health Services Research Meeting San Diego, CA June 5, 2004

  2. Colleagues: Sally Adams, Ph.D.1, Joan Orrell-Valente, Ph.D.1, Julie Lustig, Ph.D.1, Susan Millstein, Ph.D.1, Charles Wibbelsman, M.D.2, Charles E. Irwin, Jr., M.D.1 1 University of California, San Francisco, Department of Pediatrics, Division of Adolescent Medicine 2 Kaiser Permanente, California

  3. Supported by:The AAMCthrough a cooperative agreement with theCenters for Disease Control and Prevention (CDC)&Agency for Health Care Research and Quality (AHRQ)&The California Wellness Foundation & Maternal & Child Health Bureau (MCHB)

  4. BACKGROUND • Majority of adolescent morbidity/ mortality is preventable

  5. Leading Causes of Mortality in Adolescents Ages 10-19, 2001

  6. MORBIDITY/MORTALITY • Accidents and injuries leading cause of death for both males and females • Many of these accidents involve alcohol and other substances

  7. 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

  8. 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)

  9. PROMOTE ADOLESCENT HEALTH • Requires participation of • Adolescents • Families • Schools • Communities • Federal, state & community policies

  10. PROMOTE ADOLESCENT HEALTH • Health care system • Most adolescents see a primary care provider at least once a year

  11. ADOLESCENT CLINICAL GUIDELINES Recommend that primary care providers screen & counsel adolescent patients for risky health behaviors • MCHB - Bright Futures • AMA/GAPS • AAP/AAFP • USPSTF

  12. 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)

  13. ADOLESCENT CLINICAL GUIDELINES • Despite guidelines, current delivery of preventive services below recommended levels • Limited research on how to implement adolescent preventive services

  14. UNANSWERED QUESTION If primary care providers screen adolescents for risky health behaviors… Does it have any effect on adolescent behavior?

  15. EFFECT ON ADOLESCENT BEHAVIOR • No published studies on the behavioral/ health effects of adolescents receiving clinical preventive services across multiple risk areas • Research on behavioral interventions focus on changing a specific risk behavior (e.g. smoking)

  16. RESEARCH GOALS • Develop and evaluate a system intervention to increase the delivery of adolescent clinical preventive services • Evaluate the effect of preventive screening and counseling on adolescent behavior

  17. ADOLESCENT HEALTHCARE • Most adolescents receive health care through a managed care system • Utilize Pediatric clinics within Kaiser Permanente, N. CA to conduct research

  18. RISK AREAS • Risky behaviors associated with major morbidity and mortality in adolescence: • Tobacco • Alcohol • Drugs • Sexual Behavior • Seatbelt • Helmet

  19. ADOLESCENT BEHAVIORAL OUTCOMES INTERVENTION IN KAISER SYSTEM IMPLEMENTATION OUTCOMES • 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

  20. RESEARCH GOAL 1 • Develop and evaluate a system intervention to increase the delivery of adolescent clinical preventive services

  21. SYSTEM INTERVENTION TO INCREASE DELIVERY OF CLINICAL PREVENTIVE SERVICES CURRENT DELIVERY OF PREVENTIVE SERVICES IMPROVED DELIVERY OF PREVENTIVE SERVICES Provider Training Tools Health Educator

  22. TRAINING • 8-Hour Training for Pediatric Primary Care Providers • Adolescent Health and Development • Effective Communication with Adolescents • Gave Clinicians Targeted Specific Messages about Risk Behaviors

  23. 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

  24. GUIDELINES FOR PROVIDER INTERVENTION • Not Engaging in Risky Behavior • Confirm questionnaire response • Reinforce positive behaviors

  25. GUIDELINES FOR PROVIDER INTERVENTION • Engaging in Risky Behavior • Confirm response • Express concern about risky behavior • Provide key messages

  26. KEY MESSAGESKey Messages for Sexual Behavior Message 1 Avoiding sex is the safest way to prevent pregnancy and sexually transmitted diseases or AIDS.

  27. KEY MESSAGESKey Messages for Sexual Behavior Message 2 If you choose to have sex, be responsible. Use a condom every time you have sex. If you don’t have a condom, don’t have sex. To ensure you don’t get pregnant or get your partner pregnant, and as a backup to a condom, use another form of birth control such as oral contraceptives or Depo Provera.

  28. HEALTH EDUCATOR • Additional clinic staff • Reinforces provider preventive health messages • Focuses on each adolescent’s primary risk areas • Facilitates referrals

  29. HEALTH EDUCATOR • Consistent with Social Cognitive Theory: • Specific area of behavior change • Focusing on the expected outcomes of the behavior • Setting an achievable goal • Building skills and confidence to change behavior

  30. INTERVENTION PROCEDURE • Adolescent Health Screening Questionnaire prior to well-visit • Provider well-visit • Utilizes Charting Form to deliver preventive services • 20 to 30 minutes • Health Educator visit • 15 to 30 minutes

  31. SUMMARY OF IMPLEMENTATION RESEARCH - GOAL 1 • Demonstrated the efficacy of providing training, tools and additional health education resources as a method for improving preventive screening and counseling with adolescents • Screening rates increased from an average of 47% to 94% across multiple risk areas (Ozer, Adams, Lustig et al., 2001, Health Services Research)

  32. ADOLESCENT BEHAVIORAL OUTCOMES INTERVENTION IN KAISER SYSTEM IMPLEMENTATION OUTCOMES • 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

  33. RESEARCH GOAL 2 • Evaluate the effect of preventive screening and counseling on adolescent behavior

  34. DESIGN ACROSS 3 PEDIATRIC CLINICS

  35. LONGITUDINAL INTERVENTION SAMPLE • Adolescents recruited from scheduled well-visits in 3 large Pediatric clinics within Kaiser Permanente, N. CA (1999-2000) • N = 1,233 • 14 Years of age • 51% female • Agreed to return to clinic at ages 15 & 16 for well-visits

  36. Ethnicity of Adolescents

  37. COMPARISON SAMPLES

  38. PRE-INTERVENTION COMPARISON SAMPLE • Adolescents recruited from scheduled well-visits in the same 3 Pediatric Clinics PRIOR TO preventive services intervention (Fall 1998) • N = 633 • Cohort sample of adolescents ages 14, 15, & 16 • 50% female • Did not enroll in longitudinal component of study

  39. STUDY TIMELINE ACROSS 3 CLINICS

  40. COHORT COMPARISON SAMPLES • Population-based CA sample • Kaiser Permanente, N. CA • Non-Intervention Pediatric Clinics

  41. RESULTS Health Behavior Rates for Intervention and Comparison Samples

  42. SUMMARY OF PRE-INTERVENTION COMPARISON SAMPLE • At age 14, behavior rates in the pre-intervention and intervention samples were similar, suggesting that risk levels were comparable • At age 15, intervention adolescents report significantly lower rates of risky behavior in every area except drug use, compared to those in the pre-intervention sample

  43. COHORT QUESTION • While results are promising, potential problem of cohort effects: Did all adolescents in N. CA decrease risky behavior in the years 2000 to 2001 (between ages 14-15)?

  44. COHORT QUESTION • To address this question, we utilize additional cohort comparison groups from N. CA to compare engagement in risky behaviors

  45. COMPARISON DATA SETS • POPULATION-BASED SAMPLE CALIFORNIA HEALTH INTERVIEW SURVEY (CHIS) - 2001 • State-wide health survey of California’s adults, adolescents and children • Randomly selected household telephone survey • Utilized data from adolescents who said that they had a well-visit within the past year

  46. COMPARISON DATA SETS • N. CA KAISER PERMANENTE Well-visits in non-intervention Pediatric clinics • Shafer, Tebb, Pantell et al., 2000 • Irwin & Ozer, 2001-02
