NCT03709602

Brief Summary

The purpose of this research study is to find out which factors influence parents' ability to complete the human papillomavirus (HPV) vaccine series for their child. The information learned from this study may help the investigators develop programs to improve HPV vaccine completion rates among adolescents and reduce barriers to receiving the second shot of the vaccine series.

Outcome Measures

Primary Outcomes (1)

  • Overall HPV Vaccine Completion Rates

    Adolescents who completed the required HPV vaccine doses (e.g. two or three doses based on the CDC's vaccine administration guidelines for adolescents' ages 11 to 14 years) during the January 2017 to February 2019 observation period.

    up to 14 months

Secondary Outcomes (1)

  • HPV Vaccine Completion Within 14-Months

    within 14 months

Study Arms (3)

Adolescents ages 11 to 14 years

Adolescents ages 11 to 14 years who have received 1 dose of the HPV vaccine series between January 2017 and December 2017

Parent of adolescents

Parents as defined as the adolescent's biological mother or father, step-parents, or legal guardian, and who self-identified as the primary caregiver of the adolescent child and most likely to make medical decisions for the adolescent.

Cohort of Adolescents From Electronic Health Record (EHR)

A cohort of adolescents ages 11 to 14 who received 1 dose of the HPV vaccine from January 2017 to December 2017 within the university's health system network. The cohort was followed from January 2018 to February 2019 to assess vaccine completion within a 14-month period.
