Adolescent Vaccination Reminder Study
This protocol describes a study about vaccination uptake among adolescents. The purpose of the study is to determine whether parents who receive email reminders will be more likely to obtain Tdap, HPV (human papilloma virus), meningococcal, and influenza vaccines for their adolescent children than parents who do not receive email reminders.
|Study Design:||Allocation: Randomized

|Official Title:||Adolescent Vaccination Reminders Using Email|
- New immunization doses [ Time Frame: New immunizations within 60 days of reminder notification ] [ Designated as safety issue: No ]To examine the effect of email vaccination reminders, new immunization doses (for four adolescent vaccines) of children of parents who receive email vaccination reminders, versus those who do not receive email reminders during the study period will be determined.
- Waived immunization doses [ Time Frame: Waived immunizations within 60 days of reminder notification ] [ Designated as safety issue: No ]To examine the effect of email vaccination reminders, waived immunization doses (for four adolescent vaccines) of children of parents who receive email vaccination reminders, versus those who do not receive email reminders during the study period will be determined.

Experimental: Vaccination Email Reminder
This group of parents in the study will receive email notifications about due/overdue vaccines for their adolescents. Vaccination records will be reviewed to identify adolescent patients in both practices who are newly eligible for a vaccine and/or overdue for a vaccine at the start of every other month. Email notifications will then be sent to the parents of these children.
Behavioral: Email Notification
This study will use a targeted email reminder/recall intervention that addresses specific aspects of adolescent under-immunization.
No Intervention: Usual Care
This group of parents in the study will not receive email notifications about due/overdue vaccines for their adolescents.
Adolescents are a reservoir population for a variety of vaccine preventable diseases (VPDs). Despite this, adolescent vaccination rates lag substantially behind national goals of 80% coverage for adolescent vaccines set forth by Healthy People 2020. This has been particularly the case for the vaccines most recently recommended for adolescents, such as the HPV (human papilloma virus) and seasonal influenza (flu) vaccines; national coverage levels in 2010 for HPV were 32% (for series completion among females only) and 35% for flu vaccine. Uptake levels for the two other adolescent-targeted vaccines, tetanus-diphtheria-acellular pertussis (Tdap) and meningococcal conjugate (MCV4) vaccines are currently at 69% and 63%, respectively.
A major barrier to increased adolescent vaccination levels is the lack of parental and provider recognition that an adolescent is due for vaccine doses. For providers, there are the dual challenges of getting adolescents to come in for annual preventive care visits and also minimizing "missed opportunities" for vaccination (i.e. clinical interactions with a patient where a needed vaccine could have been provided but was not). Reminder/recall systems are one mechanism to help address both of these challenges for providers while also informing parents about the need for adolescent vaccines.
