An interventional study of Protect Me 4 Application + External Quality Improvement Support and Protect Me 4 Application Alone in Human Papillomavirus (HPV) Vaccines, sponsored by University of Florida. Not yet recruiting at 1 site in United States. Open to participants aged 18 Years to 99 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-14.
Sponsored by University of Florida · Not applicable, Interventional, and Health services research
Human papillomavirus (HPV) vaccines have potential to prevent an average of 26,900 cancer cases each year in the United States, but vaccine coverage rates remain low. The study team has developed an electronic application (app), Protect Me 4, to help parents and providers assess and have more productive conversations about needed vaccines.
The specific aims of this study are to: (1) evaluate the feasibility of implementing Protect Me 4, and (2) estimate preliminary efficacy of Protect Me 4 to increase HPV vaccine initiation (receipt of first dose).
Human papillomavirus (HPV) vaccines have potential to prevent an average of 26,900 cancer cases each year in the United States, but vaccine coverage rates remain low. The study team has developed a health information technology (HIT) electronic application (app), Protect Me 4, to help parents and providers assess and have more productive conversations about needed vaccines.
In past studies, Protect Me 4 users have demonstrated three times higher chances of initiating the HPV vaccine. Despite this promise, Protect Me 4 system implementation suffered from very low reach within clinics. In this phase of the project, the investigators will assess the feasibility of implementing Protect Me 4 in community clinics, as well as test vaccination rate data collection strategies and estimate the preliminary efficacy of Protect Me 4 to increase HPV vaccine initiation. Seven clinics will participate in the study, and three will be randomly assigned the use of Protect Me 4. Three of the clinics will act as controls and will not receive Protect Me 4. The final clinic will receive the intervention (but has not participated in any of the intervention development. This clinic will s as a demonstration clinic for the subsequent R01.
For evaluation, vaccination records will be grouped in three-month periods [initial (months 1-3), implementation (months 4-6) and maintenance (months 7-9)] from Medicaid and CHIP (Children's Health Insurance Program) claims and Florida Immunization Registry data. During the implementation period (months 4-6), intervention clinics will receive the Protect Me 4 app and External Quality Improvement Support (practice facilitation and external and internal provider peer opinion leaders and provider incentives). During the maintenance period (months 7-9), intervention clinics will receive Protect Me 4 without external support (practice facilitation and external provider peer opinion leaders).
To evaluate effectiveness at the individual-level, the study team will compare vaccination rates between eligible adolescents who visited intervention and control clinics across the three time periods.
Exclusion Criteria:
Parents of 11-12 year old children who visit participating interventional clinics during study period.
Behavioral: Protect Me 4 Application + External Quality Improvement Support · Behavioral: Protect Me 4 Application Alone
Health care providers and clinic staff for 11-12 year old patients at 4 participating pediatric clinics.
Behavioral: Protect Me 4 Application + External Quality Improvement Support · Behavioral: Protect Me 4 Application Alone
Adolescents between 11-12 years of age. Adolescent vaccination data is used in the study, adolescents will assent to participate. The parents, however, use the HIT system.
Parents of 11-12 year old children who visit participating control clinics during study period.
Health care providers and clinic staff for 11-12 year old patients at 3 participating pediatric control clinics.
Participants will be asked to interact with the Protect Me 4 application, using an iPad tablet. During the implementation period (months 4-6), intervention clinics will receive the Protect Me 4 app and External Quality Improvement Support (practice facilitation and external and internal provider peer opinion leaders and provider incentives). Providers from intervention clinics will complete audit and feedback reports to assess HPV vaccination rates with the assistance of the practice facilitator. Providers at the intervention clinic will complete a pre-intervention survey to obtain background information (demographics, approximate HPV vaccination rates, comfort with the use of technology etc.)
During the maintenance period (months 7-9), intervention clinics will receive Protect Me 4 without external support (practice facilitation and external provider peer opinion leaders). Providers from intervention clinics will complete audit and feedback reports to assess HPV vaccination rates without the assistance of the practice facilitator. Providers at the intervention clinic will complete a post-intervention survey to gain provider feedback regarding the feasibility of Protect Me 4 and changes in perceptions regarding the use of technology.
Also known as: Enhanced HIT System Intervention
Reach - Feasibility
Goal will be to have 80% of the parents of 11-12 year olds offered the Protect Me 4 app.
Time frame: After month 9
Adoption - Feasibility
Goal will be to have 70% of parents complete the Protect Me 4 app for each provider. App will be considered feasible of 80% or more of providers use the app during the study.
Time frame: After month 9
Provider-level Implementation - Feasibility
Goal will be to have providers report using the discussion tips approximately half the time they are provided and offering HPV vaccine 75% of the time it is due. App will be considered feasible if providers view shot lists for 60% of their patients with screens indicating that shots are due. Will aim for providers to look at specific hesitations reported by parents 60% of the time they login to the app and hesitations are reported.
Time frame: After month 9
Parent-level Implementation - Feasibility
Goal will be to have 95% of people who start the app successfully enter the app and 80% agree to participate (consent and assent.)
Time frame: After month 9
Maintenance - Feasibility
During months 7-9, the study team will assess clinic and provider maintenance of use of the Protect Me 4 app
Time frame: Months 7-9
Acceptability - Feasibility
At both the end of the implementation and the maintenance period, providers will complete the Post Intervention Survey.
Time frame: Month 6, Month 9
Data Collection Strategy
Analysis of de-identified participant datasets linked to clinic records, HIT participation date, and vaccinations from the Florida Medicaid and CHIP claims or the Florida Immunization Registry data.
Time frame: After month 9
Efficacy Measurements
Determination of HPV vaccine initiation using Current Procedural Terminology (CPT) and Current Vaccine Administered (CVX) codes
Time frame: After month 9
