1  Adolescent Immunization in Primary and Alternative Settings, and Health Care Utilization
Peter G. Szilagyi MD MPH Department of Pediatrics University of Rochester School of Medicine and Dentistry

2 Who are these people? Why are they important for adolescent immunizations?

3 Outline Where should adolescents be vaccinated?
Primary care Other settings What should change in primary care settings? What are the benefits of adolescent vaccination? We focus on two major research questions: We study methods to improve immunization delivery, particularly for poor children or those with chronic conditions. Second, we study implementation of new vaccines, using a “benches to trenches” approach. Studies include basic laboratory work to identify viruses, clinical investigation to measure disease burden, and health services research to study how best to deliver new vaccines.

5 Definition of Adolescent
11-21 years of age 40 million across the US 14% of the US population

6 Current Utilization of Healthcare Among Adolescents across the US (Summary of Studies)
Methods Analyses of two national datasets MEPS ( ) NAMCS/NHAMCS (2002) Assess utilization by Age, Gender, demographics Determine types of health providers seen

7 The critical role of primary care

8 Percent of Adolescents with a Usual Source of Care
Summary from several studies

9 Receipt of Ambulatory Care* Within 1 Year Among Females
*Ambulatory care- Any visit to a physician, nurse/nurse practitioner, physician assistant or midwife Christina Albertin et al. PAS Meetings, 2006

10 Receipt of Ambulatory Care* and Primary Care ** Within 1 Year
*Ambulatory care- Any visit to a physician, nurse/nurse practitioner, physician assistant or midwife **Primary care- Any visit to a pediatrician, family physician, internist or general practitioner in an office-based practice or clinic.

11 Receipt of Ambulatory Care* and Primary Care ** Within 1 Year
Most visits are to primary care *Ambulatory care- Any visit to a physician, nurse/nurse practitioner, physician assistant or midwife **Primary care- Any visit to a pediatrician, family physician, internist or general practitioner in an office-based practice or clinic.

12 Receipt of Ambulatory Care* and Primary Care ** Within 1 Year
Most visits are to primary care Less so for older girls *Ambulatory care- Any visit to a physician, nurse/nurse practitioner, physician assistant or midwife **Primary care- Any visit to a pediatrician, family physician, internist or general practitioner in an office-based practice or clinic.

13 Receipt of Ambulatory Care and Primary Care Within 1 Year by Age Year and Gender
*Ambulatory care- Any visit to a physician, nurse/nurse practitioner, physician assistant or midwife **Primary care- Any visit to a pediatrician, family physician, internist or general practitioner in an office-based practice or clinic.

14 Receipt of Ambulatory Care and Primary Care Within 1 Year by Age Year and Gender
Younger boys: same as girls Older boys: use less care *Ambulatory care- Any visit to a physician, nurse/nurse practitioner, physician assistant or midwife **Primary care- Any visit to a pediatrician, family physician, internist or general practitioner in an office-based practice or clinic.

17 Who is this person? Why is this important for adolescent immunizations?

18 Who is this person? Why is this important for adolescent immunizations?
In attempting to diagnose a problem, first do the experiment that can confirm the most likely diagnosis

19 Who is this person? Why is this important for adolescent immunizations?
Why do you rob banks?

20 Who is this person? Why is this important for adolescent immunizations?
Because that’s where the money is Why do you rob banks?

21 Who is this person? Why is this important for adolescent immunizations?
Willy Sutton (bank robber) Because that’s where the money is Why do you rob banks? Sutton’s Law: In attempting to diagnose a problem, first do the experiment that can confirm the most likely diagnosis

22 Critical Role of Primary Care
Most adolescent visits are to primary care Major sources of healthcare: Young and middle teens: pediatricians & family MDs Older girls: add OB-GYNs Thus, focus adolescent immunizations towards: Primary care (pediatricians and family physicians) Younger adolescents

46 No Visits to Medical Homes in Prior Year

47 No Visits to Medical Homes in Prior Year
More likely if: Poor Uninsured Minority

48 No Visits to Medical Homes in Prior Year
More likely if: Poor Uninsured Minority We need to: help get adolescents in for healthcare visits Patient reminders Improved access

49 Few Preventive Visits

50 Few Preventive Visits 1/3 - 2/3 of teens have a preventive visit within a year Most visits to primary care are NOT preventive visits

51 Few Preventive Visits 1/3 - 2/3 of teens have a preventive visit within a year Most visits to primary care are NOT preventive visits Medical Homes should: -Focus on  preventive visits -Vaccinate during other visits -Vaccinate while young (more preventive visits)

52 Medical homes will need to bring adolescents in for more visits

53 Special Case- HPV Vaccine

67 Benefits to Adolescent Vaccinations
Reduce vaccine preventable diseases HPV, Pertussis, Meningococcus, Hepatitis, Varicella, Tetanus, Influenza Reduce spread of infections (“herd immunity”) Might lead to improvements in other services Medical homes: Preventive services Macro level: Health insurance and systems for teens More coordinated care across healthcare settings Renewed focus on the adolescent population

71 Summary Lessons from Current Utilization Patterns
Focus on primary care settings Pediatrics, Family MD, OB-GYN (for older girls) Consider “some” alternative settings (for subgroups) Schools, Teen-oriented settings, ? ED in some cases? Rethink strategies within medical homes More preventive visits, Vaccinate at all visits Tracking, reminder, recall Consider benefits of adolescent immunizations Vaccine preventable diseases Additional benefits to adolescent health care
