HPV Vaccine Hesitancy Among Indiana Youth With Cancer and Blood Diseases

May 7, 2024 updated by: Scott L Coven, DO, MPH, Indiana University
For the identified groups of patients (survivors of childhood cancer and youth with sickle cell disease) the investigators want to better understand the barriers to, and facilitators of, HPV vaccination. Through HCP interviews the investigators will also assess both attitudinal and logistical obstacles to HPV vaccination. Some subspecialty HCPs may believe, for instance, that it is the primary care provider's responsibility to vaccinate or they may be unfamiliar with the requirement to enter vaccination data into CHIRP. Also, in some cases HPV vaccine may not be readily available in subspecialty clinic locations and/or subspecialty HCPs may not be Vaccines for Children (VFC) providers. Participants: the investigators will focus on two patient groups: survivors of childhood cancer, which includes children aged 9-21 years who have completed active therapy for cancer and are eligible for vaccination, and sickle cell disease, which includes children aged 9-21 years with a diagnosis of sickle cell disease. The investigators will recruit parents of children aged 9-21 years and older adolescents aged 18-21 years. For pediatric patients, the investigators selected a lower age of 9 years because HPV vaccine is licensed down to 9 years of age, and an upper limit of 21 years, as that is considered the upper bound of adolescence by the American Academy of Pediatrics. For patients 9-17 years of age, only parents will be interviewed by video or phone because parents are the vaccine decision-makers. For patients 18-21 years of age, the investigators will interview both young adults and their parents, because, while the young adult has legal decision-making capacity, in reality, the decision is frequently made jointly by the young adult and parent, and older adolescents are frequently unwilling to go against their parents' wishes. All research procedures will be conducted in English. Participants will be excluded if they have an intellectual disability or severe medical illness such that they are unable to consent or to understand the questions.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

9 years to 75 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with sickle cell disease or cancer. Caregivers of patients with sickle cell disease or cancer. Healthcare providers of patients with sickle cell disease or cancer.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Vaccine Hesitancy 5 point Likert scale
Time Frame: 1 Day
Patients will be scored using scale: 1=strongly disagree; 2=disagree; 3=neither agree nor disagree; 4=agree; and 5=strongly agree; lower scores mean less confidence/more hesitancy; higher scores mean more confidence/less hesitancy.
1 Day
Vaccine Hesitancy 5 point Likert scale
Time Frame: 1 Day
Caregivers will be scored using scale: 1=strongly disagree; 2=disagree; 3=neither agree nor disagree; 4=agree; and 5=strongly agree; lower scores mean less confidence/more hesitancy; higher scores mean more confidence/less hesitancy.
1 Day
Hesitancy or Confidence of counseling or giving the HPV vaccine of health care providers
Time Frame: 1 Day

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
