Cynthia Rand, MD, MPH
University of Rochester School of Medicine and Dentistry
Outline
Adolescent healthcare utilization
• Visit-based data (NAMCS)
• Population-based data (MEPS)
• Additional visit burden for universal HPV vaccine delivery (MEPS)
National Healthcare Visit Patterns of Adolescents
• 1994-2003 NAMCS (office-based) and NHAMCS (hospital-based) combined
• Visit-based database
• Visit patterns by age and gender
– Overall visits
– Preventive visits (V20.2, V70.0, V70.3, V70.5, V70.6, V70.8, V70.9)

Population Based Analysis:Adolescent Healthcare Utilization
• MEPS 2002-2003
• Adolescents ages 11-21
• Parent or self-report of ambulatory care
• Primary care in past year (Peds, IM, FP, GP in office based practice or clinic)
• Includes all adolescents, even if not receiving care
Ambulatory and Primary Care Within 1 Year: Females
C. Albertin, et al., presented at Pediatric Academic Societies’ Meeting, May 2006
•Ambulatory care: Visit to a physician, nurse/nurse practitioner, physician assistant or midwife
**Primary care: Had a visit to a pediatrician, family physician, internist or GP in an office-based practice or clinic

Adolescent Factors Associated With No Ambulatory Care
• Age– Older age (17-21 yrs old) for male
adolescents
• Race/Ethnicity– Other than white
• Income– All income levels less than 400% FPL
Potential Healthcare Visit Needs for Universal HPV Vaccine Delivery
• Primary care visits in 2002-2003 MEPS
• Determined whether 0, 1, 2 or 3 more visits needed
• Varied window of time to vaccinate
• Two scenarios:
– 1st vaccine given at a well visit
– 1st vaccine given at any visit

Independent Predictors of Needing More Visits (2-3 vs. 0-1) in 24 months
• Adolescents more likely to need more visits:– Older age– Male– Black– Uninsured– Near-poor
Limitations
• NAMCS/NHAMCS well visit defined by ICD-9 code documented
• MEPS well visit defined by parent report if <17
• Alternative sites not well identified (teen clinics, family planning clinics, etc)
Conclusions
• 30% of adolescents receive no care in 12 months
• >50% have primary care visits, declines with age• Peds/FP major care providers to age 16• Females continue to receive care, more from
ob/gyn with older age• Male adolescents drop off from care after age 16• Few adolescents have sufficient visits for 3
vaccines
Implications
• Immunize preferentially in early/mid adolescence
• Ob/gyns should reach older adolescent females with vaccines if missed earlier
• Avoid missed opportunities for vaccination
• Consider delivering series at wider intervals
Future Questions
• How to encourage annual visits for adolescents?
• How to access those not getting care in the medical home?
• Do vaccine delivery strategies that work for younger children work for adolescents?
• Can a vaccine series be given annually? (HPV)
