Advancing HPV Vaccination Among HIV Positive Adults: The CHAMPS Study

Study Overview
=================
Brief Summary
-----------------
People living with HIV (PLWH) are 28 times more likely to be diagnosed with Human Papillomavirus (HPV) - associated anal cancer than the general population. The HPV vaccine is an effective and safe approach to prevent and reduce the risk of HPV-related disease among PLWH. HPV vaccine programs tailored and implemented in the HIV population are lagging for this high-risk group. The CDC's 4 Pillars Transformation Program is a multi-level, evidence-based intervention that has been successfully used to increase HPV vaccination in the general population and is ready to be tested in the high-risk HIV population, particularly PLWH in the rural South. This program offers providers and clinic staff evidence-based strategies to increase HPV vaccination uptake via training and educational resources. This study proposes to tailor and refine the 4 Pillars Program and do this project in three HIV clinics in Georgia (AID Atlanta, AID Newnan, and Albany Model Rural HIV Clinic) and enroll n=365 PLWH who are age 18-45 years from those clinics.

Detailed Description
-----------------
People living with HIV (PLWH) are 28 times more likely to be diagnosed with HPV- associated anal cancer than the general population. The HPV vaccine is an effective and safe approach to prevent and reduce the risk of HPV-related disease among PLWH. However, in previous pilot studies, there were significant gaps found in knowledge and awareness of the HPV vaccine as well as low receipt of the HPV vaccine (13.5%) in our population of rural PLWH. HPV vaccine programs tailored and implemented in the HIV population are lagging for this high-risk group. The Center for Disease Control's (CDC) 4 Pillars Transformation Program is a multi-level, evidence-based intervention that has been successfully used to increase HPV vaccination in the general population and is ready to be tested in the high-risk HIV population, particularly PLWH in the rural South. Thus, this study proposes to tailor and refine the 4 Pillars Program and do this project in three HIV clinics in Georgia (AID Atlanta, AID Newnan, and Albany Model Rural HIV Clinic) and enroll n=365 PLWH who are age 18-45 years from those clinics. To be included in the study, interested participants must meet the following criteria: Patients enrolled in the study will meet the following criteria: 1) HIV positive; 2) 18-45 years of age; 3) read and speak English; 4) capable of informed consent; 5) have not been previously received the three series HPV vaccine; 6) no contraindications to receiving the HPV vaccine. The 4 Pillars Program offers providers and clinic staff evidence-based strategies to increase HPV vaccination uptake via training and educational resources. Providers and clinic staff who are interested in participating will enroll online and complete an electronic informed consent before participating in the focus groups and completing the evaluation surveys. Providers and clinic staff will be offered an opportunity participate in an in-service training (CE units will be available) that will provide education and resources on the 4 Pillars program and will learn more about HPV, HPV vaccination, and HPV-associated cancers. Providers and clinic staff will be asked to recommend and administer the HPV vaccine during each routine clinic visit. Consenting providers and clinic staff will be asked to complete pre-intervention evaluations, an intervention evaluation every 3 months, a post-evaluation, and post-intervention evaluations. For patient enrollment, the research coordinator, with assistance from a clinic-designated Immunization Champion (IC), will review the clinic's appointment schedule to call patients in the target age range (18- 45 years of age) one week in advance of their appointments to inform them of the study and to determine eligibility. If eligible and interested in the proposed study, the individual will be given an overview of the research study, including purpose, what participation entails, potential risks and benefits of participation, and measures that will be used to ensure confidentiality. Participants will be assured participation is completely voluntary and that they may withdraw from the study at any time without consequences. If the individual volunteers to participate in the study, an electronic informed consent will be obtained by the research assistant(s) via REDCap. Participants will be asked to consent to have their HPV vaccination status confirmed via electronic medical records and GRITS. Participants will then watch a short video on HPV and HPV vaccines that can be viewed on their phones (or the clinic's iPad) while waiting to be seen. Potential participants will be asked to follow the study's private Facebook page which will offer additional educational information tailored towards individuals with HIV on HPV-related disease and general health promotion and risk reduction tips. A post-intervention evaluation will be provided after the third immunization is given or due (if missed).

Design Details

Primary Purpose: Prevention
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: The study will be implemented at the clinic, Provider, and Patient levels. Every level will receive a different intervention or none in the case of the control. Clinic and Provider level will receive training on recommending and administering the vaccine at the clinic. Patient level will accept or decline the recommendation for the HPV vaccine. The Control arm will be collected from EMR and the GRITS database from patients not receiving the vaccine before the intervention period.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: 4 Pillars Program<br>Patients at study clinics who consent to have their HPV vaccination history verified with the Georgia Registry of Immunization Transactions and Services (GRITS). | Behavioral: CDC 4 Pillars Program<br>* The CDC's 4 Pillars Transformation Program (4 Pillars Program) is a robust and empirically supported strategic approach that promotes the uptake of adult vaccinations and addresses facilitators and barriers at the patient, provider, and clinic level. This multi-level, evidence-based intervention has been successfully utilized to increase HPV vaccination in the general population and is primed to be tested in the high-risk HIV population, particularly PLWH in the rural South. This proposal seeks to expand the success of the 4 Pillars Program and tailor, refine, and implement in the HIV positive population who are at extraordinarily high risk for HPV-related cancers and can obtain the most benefit from the vaccine.<br>|
| No Intervention: Adjacent time-period Control Group<br>The background HPV update rate among PLWH will be obtained by using the electronic medical record (EMR) and GRITS to identify HPV vaccination uptake 18 months prior to the intervention. These data are collected retrospectively and no study participants are prospectively assigned to this study arm. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of patients initiating the HPV vaccine | Initiation of the HPV vaccine is defined as receiving the first or second immunization from the series. This variable will be measured by electronic medical records and GRITS at 24 months post baseline. | 24 months post baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of participants completing the HPV vaccine | Completion is defined as receiving all 3 immunizations from the series, regardless of time. This variable will be measured by electronic medical records and GRITS 24 months post baseline. | 24 months post baseline | 
| Change in uptake rate of vaccination | The team will calculate the percent change in initiation of the vaccine and percent change in completion of the vaccine from the control phase and 24 months post intervention, after adjusting for demographics differences in population. | Baseline and 24 months post baseline |
