Effect of an HPV Vaccination Multi-Level, Multi-Component Program on HPV Vaccination Initiation and Completion in a Pediatric Clinic Network.

Despite clear evidence of the public health benefits of the human papillomavirus (HPV) vaccine in preventing HPV-related cancers and genital warts, underutilization of HPV vaccination in the United States persists. Interventions targeting multi-level determinants of vaccination behavior are crucial for improving HPV vaccination rates. The study's purpose was to implement and evaluate the adapted Adolescent Vaccination Program (AVP), a clinic-based, multi-level, multi-component intervention aimed at increasing HPV vaccine initiation and completion rates in a five-clinic pediatric network in Bexar County, Texas. The adaptation process was guided by established frameworks and involved formative work with clinic stakeholders. The study utilized a quasi-experimental single group pre- and post- study design, with an external comparison data using the National Immunization Survey-Teen (NIS-Teen) datasets for the same time period to examine the AVP's effect on HPV vaccination initiation and completion. A series of interrupted time series analyses (ITSA) compared the clinic system patient outcomes (HPV vaccination initiation and completion rates) in the post-intervention to the general adolescent population (NIS-Teen). Of the 6438 patients (11-17 years) with clinic visits during the 3-year study period, HPV vaccination initiation rates increased from 64.7% to 80.2% (p < 0.05) and completion rates increased from 43.2% to 60.2% (p < 0.05). The AVP was effective across various demographic and economic subgroups, demonstrating its generalizability. ITSA findings indicated the AVP improved HPV vaccination initiation and completion rates in clinic settings and that AVP strategies facilitated resilience during the pandemic. The minimal adaptation required for implementation in a new clinic system underscores its feasibility and potential for widespread adoption.

Adaptation and Formative Evaluation of Online Decision Support to Implement Evidence-Based Strategies to Increase HPV Vaccination Rates in Pediatric Clinics.

Human papilloma virus (HPV) vaccination rates remain below national goals in the United States despite the availability of evidence-based strategies to increase rates. The Adolescent Vaccination Program (AVP) is a multi-component intervention demonstrated to increase HPV vaccination rates in pediatric clinics through the implementation of six evidence-based strategies. The purpose of this study, conducted in Houston, Texas, from 2019-2021, was to adapt the AVP into an online decision support implementation tool for standalone use and to evaluate its feasibility for use in community clinics. Phase 1 (Adaptation) comprised clinic interviews (n = 23), literature review, Adolescent Vaccination Program Implementation Tool (AVP-IT) design documentation, and AVP-IT development. Phase 2 (Evaluation) comprised usability testing with healthcare providers (HCPs) (n = 5) and feasibility testing in community-based clinics (n = 2). AVP-IT decision support provides an Action Plan with tailored guidance on implementing six evidence-based strategies (immunization champions, assessment and feedback, continuing education, provider prompts, parent reminders, and parent education). HCPs rated the AVP-IT as acceptable, credible, easy, helpful, impactful, and appealing (≥80% agreement). They rated AVP-IT supported implementation as easier and more effective compared to usual practice (p ≤ 0.05). The clinic-based AVP-IT uses facilitated strategy implementation by 3-month follow-up. The AVP-IT promises accessible, utilitarian, and scalable decision support on strategies to increase HPV vaccination rates in pediatric clinic settings. Further feasibility and efficacy testing is indicated.

Parents' stigmatizing beliefs about the HPV vaccine and their association with information seeking behavior and vaccination communication behaviors.

Parents' stigmatizing beliefs about the HPV vaccine, such as beliefs that it promotes adolescent sexual activity, constitute a notable barrier to vaccine uptake. The purpose of this study is to describe the associations between parents' stigmatizing beliefs about the HPV vaccine, psychosocial antecedents to vaccination, and parents' intentions to vaccinate their children. Parents of vaccine-eligible children (n = 512) were surveyed in a large urban clinical network. Results indicate that two stigmatizing beliefs were significantly associated with self-efficacy in talking with a doctor about the HPV vaccine. Believing that the vaccine would make a child more likely to have sex was associated with citing social media as a source of information about the vaccine. Other stigmatizing beliefs were either associated with citing healthcare professionals as sources of information about the vaccine, or they were not significantly associated with any information source. This finding suggests that stigmatizing beliefs might discourage parents from seeking out information about the vaccine. This study is significant because it further highlights the importance of doctor recommendations to all patients at recommended ages; doctor visits may represent one of the few opportunities to normalize HPV vaccination and address parents' stigmatizing beliefs about the HPV vaccine.

AVPCancerFree: Impact of a digital behavior change intervention on parental HPV vaccine -related perceptions and behaviors.

Parent hesitancy contributes to reduced HPV vaccination rates. The HPVcancerfree app (HPVCF) was designed to assist parents in making evidence-based decisions regarding HPV vaccination. This study examined if parents of vaccine-eligible youth (11-12 yrs.) who use HPVCF in addition to usual care demonstrate significantly more positive intentions and attitudes toward HPV vaccination and greater HPV vaccination rates compared to those not using HPVCF. Clinics (n = 51) within a large urban pediatric network were randomly assigned to treatment (HPVCF + usual care) or comparison (usual care only) conditions in a RCT conducted between September 2017 and February 2019. Parents completed baseline and 5-month follow-up surveys. Participant-level analysis determined 1) change in HPV vaccination initiation behavior and related psychosocial determinants and 2) predictors of HPV vaccine initiation. Parents (n = 375) who completed baseline and 5-month follow-up surveys were female (95.2%), 40.8 (±5.8) yrs. married (83.7%), employed (68.3%), college educated (61.9%), and privately insured (76.5%). Between-group analysis of HPVCF efficacy demonstrated that parents assigned to receive HPVCF significantly increased knowledge about HPV and HPV vaccination (p < .05). Parents who accessed content within HPVCF significantly increased knowledge about HPV & HPV vaccine (p < .01) and perceived effectiveness of HPV vaccine (p < .05). Change in HPV vaccine initiation was not significant. A multivariate model to describe predictors of HPV vaccine initiation demonstrated an association with Tdap and MCV vaccination adoption, positive change in perceived effectiveness of the HPV vaccine, and reduction in perceived barriers against HPV vaccination. HPVCF appears to be a feasible adjunct to the education received in usual care visits and reinforces the value of apps to support the important persuasive voice of the health-care provider in overcoming parent HPV vaccine hesitancy.

A Healthy Retail Intervention in Native American Convenience Stores: The THRIVE Community-Based Participatory Research Study.

Objectives. To assess a healthy retail intervention in Tribal convenience stores in Oklahoma.Methods. We adapted healthy retail strategies to the context of 8 Tribally owned stores. We assessed individual- and store-level outcomes in a cluster-controlled intervention trial (April 2016-June 2017). We measured fruit and vegetable intake, store environment perceptions, and purchases before and after the intervention among a cohort of 1637 Native American shoppers. We used mixed-effects linear regression to estimate pre- to postintervention changes in and between groups.Results. We followed 74% of participants (n = 1204) 9 to 12 months. Intervention and control participants perceived healthier stores after intervention. Higher shopping frequency was related to purchases of fruits, vegetables, and healthy items.Conclusions. Intervention exposure was associated with healthy purchasing but not fruit and vegetable intake. Research is needed to further assess impacts of environmental interventions on intake.Public Health Implications. As the first healthy retail intervention in Tribally owned stores, our results contribute evidence for environmental and policy interventions to address obesity in Tribal Nations. Multicomponent interventions, led by Tribal leaders from diverse sectors, are needed to create healthy environments and sustainable improvements in Native American health.
