Trial Information

Adolescent Vaccination Kiosk Project

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 papillomavirus) 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.

Inclusion Criteria:

- Parents of adolescents (11-17 years) attending one of 3 participating pediatric

- able to read and converse in English.

Exclusion Criteria:

- Parent age < 18 years,

- prisoners,

- decisionally challenged participants.

Type of Study:


Study Design:

Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Health Services Research

Outcome Measure:

Utilization of vaccine information kiosks by parents/patients.

Outcome Description:

Descriptive statistics on kiosk utilization patterns overall, and disaggregated by various demographic, attitudinal and vaccination status categories will be derived. This will be assessed in intervention settings using data entered by parents, as well as paradata such as the order of web pages viewed, and time spent per page.

Outcome Time Frame:

12 months
