Stories to Prevent Cancer: A Pilot Study Using Cancer Survivor Narratives to Increase Human Papillomavirus Vaccine Intentions.

INTRODUCTION: Human papillomavirus (HPV) vaccination rates are lower than other recommended adolescent vaccines. Cancer survivor narratives are used to promote cancer prevention and control, but little is known about their impact on adolescent HPV vaccination. OBJECTIVE: This pilot study explored the feasibility and effects of a video education intervention using a cancer survivor narrative to improve parents' attitudes toward and intentions to get the HPV vaccine. METHODS: This study utilized a one-group design; participants completed a pre-intervention survey, watched the video before attending their sons' wellness visits, and completed a post-intervention survey within one week of their appointment. Using the narrative persuasion framework, we developed a 4-minute video of a local HPV-related cancer survivor to promote the HPV vaccine as cancer prevention. We recruited 37 participants between June and October 2020. Participants were parents of males ages 9-17 who had not yet initiated HPV vaccination. RESULTS: After the video, more parents agreed that HPV vaccination is safe (pre: 66% vs. post: 82%; P = .045) and that their child's chances of getting HPV-related cancer in the future are high (pre: 24% vs. post: 46%; P = .014). Overall, 91% of parents felt the cancer survivor story helped them understand the risks of HPV cancers, and 52% said the story influenced their decision to start HPV vaccination for their child. CONCLUSIONS: Our findings suggest that cancer survivor narratives influence parents' vaccine opinions and understanding of their child's risk of HPV infection, leading to increased parental intent to get the HPV vaccine for their adolescent males.

Increasing the adoption of evidence-based communication practices for HPV vaccination in primary care clinics: The HPV ECHO study protocol for a cluster randomized controlled trial.

BACKGROUND: The safe, highly-effective human papillomavirus (HPV) vaccine remains underused in the US. The Announcement Approach Training (AAT) has been shown to effectively increase HPV vaccine uptake by training providers to make strong vaccine recommendations and answer parents' common questions. Systems communications, like recall notices, can further improve HPV vaccination by reducing missed clinical opportunities for vaccination. Never tested in supporting HPV vaccination, the ECHO (Extension for Community Healthcare Outcomes) model is a proven implementation strategy to increase best practices among healthcare providers. This trial uses a hybrid effectiveness-implementation design (type II) to evaluate two ECHO-delivered interventions intended to increase HPV vaccination rates. METHODS: This 3-arm cluster randomized controlled trial will be conducted in 36 primary care clinics in Pennsylvania. Aim 1 evaluates the impact of HPV ECHO (AAT to providers) and HPV ECHO+ (AAT to providers plus recall notices to vaccine-declining parents) versus control on HPV vaccination (≥1 dose) among adolescents, ages 11-14, between baseline and 12-month follow-up (primary outcome). Using a convergent mixed-methods approach, Aim 2 evaluates the implementation of the HPV ECHO and HPV ECHO+ interventions. Aim 3 explores exposure to and impact of vaccine information from providers and other sources (e.g., social media) on secondary acceptance among 200 HPV vaccine-declining parents within 12 months. DISCUSSION: We expect to demonstrate the effectiveness and evaluate the implementation of two highly scalable interventions to increase HPV vaccination in primary care clinics. Our study seeks to address the communication needs of both providers and parents, increase HPV vaccination, and, eventually, prevent HPV-related cancers.

The Healthy, Immunized Communities Study: A pilot intervention to increase parents' intentions to get vaccines for their middle school children.

Pennsylvania shortened the provisional period for student vaccine compliance in 2018. We pilot tested a school-based health education intervention, The Healthy, Immunized Communities Study, to improve parents' intentions to get school-required (tetanus, diphtheria, acellular pertussis [Tdap]; and meningococcal conjugate [MCV]) and recommended (human papillomavirus [HPV]) vaccines for their children. In Phase 1, we partnered with the School District of Lancaster (SDL) to conduct four focus groups with stakeholders (local clinicians, school staff, school nurses, and parents) to inform the development of the intervention. In Phase 2, we randomized four middle schools in SDL to either the intervention (six email communications and school-community educational event) or control group. Seventy-eight parents took part in the intervention and 70 joined the control group. Vaccine intentions were compared within and between groups from baseline to 6-month follow-up with generalized estimating equations (GEE) models. Compared to the control, the intervention did not increase parents' vaccine intentions for Tdap (RR = 1.18; 95 % CI:0.98-1.41), MCV (RR = 1.10; 95 % CI:0.89-1.35), or HPV (RR = 0.96; 95 % CI:0.86-1.07). Among intervention participants, only 37 % opened ≥ 3 email communications and 23 % attended the event. Intervention participants reported high satisfaction with email communications (e.g., informative = 71 %) and felt that the school-community event met their educational objectives on key topics (e.g., immune system = 89 %). In conclusion, although we observed no intervention effect, our data suggest that this could be a result of the low uptake of intervention components. Further research is needed to understand how school-based vaccination-focused interventions can be successfully implemented with high fidelity among parents.
