Adolescence – A Challenging Time to Promote Prevention and Immunization Juan Carlos Batlle, MD ‘04 University of Pennsylvania School of Medicine Thomas K. Zink, MD GlaxoSmithKline, Immunization Policy and Scientific Affairs
Adolescence: A Hidden Opportunity • 41 million youths aged 10-19 • Age group a crucible for high-risk behavior • 45% of high school students have had sex • 10% have tried cocaine • Older adolescents not accessing health care • ~20% have foregone needed care in the past year • ~20% have no insurance or medical home • One study puts cost of preventable adolescent morbidities at $700 billion / year (Adolescent Medicine: StARs. 1999;10(1):131-151.)
Adolescent Immunity (Or Lack Thereof) • Vaccination rates range from 20-90% • 35 mm youths 11-21 missing at least one vaccine • Late 80s/Early 90s: 47% of measles cases were among adolescents/young adults • Adolescents represent 70% of the 100-140K cases/year of hepatitis B and 29% of all pertussis cases Handal G. Adolescent immunization. Adolescent Medicine: State of the Art Reviews. 2000;11(2):439-452.; MMWR 2002; 51: 73-76.
Challenges to an Adolescent Approach • Age group changeability - Adolescents are a moving target, aged somewhere between 6 and 21 • Physicians tough to target - Adolescents are not the exclusive province of any MD • Deficient data - Most health and immunization data focuses on children 0-3 • Lack of a medical targeting model - Few products prescribed primarily to teens
Teens Engage In Risky Behaviors YRBS: CDC-conducted national school-based survey of 13,601 students in grades 9-12 during Feb-Dec 2001. • 46% had ever had sex (61% of blacks). 7% had sex before age 13 (16% of blacks). • 33% of students had sex within 3 mos. of survey. • 42% had not used a condom at last intercourse. • 870,000 pregnancies/year among 15-19 year olds. • 3mm STDs among 10-19 year olds. Youth risk behavior surveillance--United States, 2001. Morbidity & Mortality Weekly Report. Surveillance Summaries. 51(4):1-62, 2002 Jun 28.
Health Care “Risk” Also Increases 1999 Add Health Study: 12,105 adolescents (grades 7-12), 1994-95 school year. • 18.7% had foregone care in the past year. • 13.0% of teens had no insurance and another 6.5% had interrupted insurance. • Uninsured teens were most likely to forego care (23.9%). • 33.0% of all teens had no physical exam in the past year.

Physician Change Fragments Care NAMCS Office Visit Data
Health Care Guidance Slowly Rising • In 1995, ACIP recommended catch-up Hep B of all children 10-12 at “early adolescent visit” • In 1996, professional societies join (AMA, AAFP, AAP) with ACIP to promote prevention-oriented early adolescent visit • Guidelines appear (Bright Futures, GAPS) • 2004 Childhood Immunization Schedule includes a preadolescent visit
Adolescent Vaccines On The Way NIAID: The Jordan Report 2002.
Messaging Is Missing • For kids <15, 50% of visits for an acute issue; only 27% for non-illness care. • In 63% of visits, no therapeutic or preventive services were ordered or provided. • HIV/STD transmission discussed in 0.6% of visits. (Counseling most often on diet, 15.0% of visits). • Yet 86% of teens 15-17 rated sexual health a “big personal concern” and the highest rated concern overall. Source: NAMCS 2000 data.

Immunization registries Physician education Improved insurance Improved access to care Middle school mandates Patient education Tracking/outreach Incentive programs Passive: Attempt to “catch” patients. Active: Influence patients to ask for immunization. “Passive-Teen” vs. “Active-Teen” Strategies
Passive Strategy: Catch the Teens • School based health clinics - Proven entities with broad support; high enrollment of teens. • Job-related efforts - Employer incentives to build in paid time for minimum wage employees to seek health care. • Mobile clinic - Access under-served or fragmented areas. Concerts, malls, etc. • Mall kiosks - Low cost, confidential clinics to administer reproductive health services, immunizations, minor acute care.
Active Strategy: Quid Pro Quo • School entry requirements - Proof of immunization at a certain grade level. • Sports participation / Camp participation requirements • Motor voter type effort - Require immunization for driver’s license or SAT exam. • Tattoo/body piercing - Policy requirement of proof of immunization.
Thought Experiment: Churn Rate • 4 mm new 10 year olds each year – how do we catch them before they are 14? • Assume 30% are immunized annually • 1.2 mm immunized each year, then? No problem immunizing all 4mm by 14. • But, some kids never present to the system • Churn rate becomes important • Need to improve % of kids newly presenting to system, “churning” in the unimmunized
Takeaways At 30% annual rate, entire cohort is easily caught if all teens presented to system. # of years of catch-up is fixed. Churn rate is crucial: Increasing teens new to system to 58.3% yields 0.7mm incremental catchup each year and no lost teens The Churn Factor New 10 yr olds 4mm Imm. rate (4mmx30%) -1.2mm Churn Rate 58.3% Incremental gain/yr -0.7mm (-4mmx58.3%x30%) Years of catch-up 4yrs Incremental Catchup (-0.7mmx4yrs) -2.8mm Lost 10 year olds 0 Getting Teens Into System Is Key
Alternative Care Sites Simulate Churn • Clinics catch teens outside the traditional patient-doctor relationship • School-based health centers • Planned Parenthood / Teen clinics • HMO-based clinics • Immunization programs similarly catch teens • Motor/voter type drives • Canvassing campaigns • “Vaccinate Before You Graduate” • 70%+ of physicians agree that alternative care sites are acceptable for immunization.
Other Tools Effective At Churn • CHIP Enrollment: CHIP children were 85.6% UTD on at 24 months compared to 54% of non-CHIP • Tracking/Outreach: Increased mean health visits by 0.44/child/yr; raised immunization rate 20 % points. • Information systems: AFIX, using CASA system, increased immunization rate by 10 % points in 1 year in Maine. • Immunization drives: Baton Rouge drive immunized 5000 teens in 5 years with little financial support; GET HEP B in Missouri.

Expanding Physician Involvement Family Physicians • 33% to 50% of adolescent visits made to FP Emergency Physicians • 25% of adolescent visits to ER (13mm visits) OB/GYNs • Reach almost all women • Represent 40%-50% of all female teen visits Ramifications • Insurance coverage; new CPT codes • Patient / parent / provider attitudes
Milestone Prevention Visits As A Tool • Pre-adolescent visit at age 10-12 • Recommended visits at age 5, 10, 15, 20?
