Evaluation of a Brief Intervention to Improve Human Papillomavirus-Related Awareness, Knowledge, and Attitudes Among Ethnically and Sexually Diverse College Students

Human papillomavirus (HPV) is a preventable infection responsible for anogenital and oropharyngeal cancers, as well as genital warts. Two safe and effective vaccines are recommended for adolescents and young adults to protect against HPV infection. Both are severely underutilized. Sexual and ethnic minorities are disproportionately affected by HPV infection and its sequelae. The goals of this study were to (1) assess baseline differences in HPV-related awareness, knowledge, and attitudes between men and women, and (2) evaluate the differential efficacy of a brief, educational HPV intervention among ethnically and sexually diverse college students. Students attending undergraduate courses from 2015 to 2017 participated in a brief, tailored, classroom intervention designed to improve HPV-related awareness, knowledge, and attitudes. These outcomes were assessed immediately before and following an evidence-based educational presentation about HPV risks, outcomes, treatments, and prevention. At baseline, 84% of participants (N=386) had heard of HPV; 28% of men and 55% of women reported receiving ≥1 dose of HPV vaccine. Vaccinated women were seven times more likely to report favorable attitudes than unvaccinated women (RR=7.1, CI[3.3-15.5]). Hispanic participants had more positive attitudes toward HPV vaccination (62% vs. 44%; P=0.009) and were more willing to become vaccinated (66% vs. 46%; p=0.02) than non-Hispanic participants at baseline. Gay and bisexual men (92%) were more likely than heterosexual men (68%) to have heard of HPV, to receive any doses of HPV vaccine (37% vs 19%), to view HPV vaccination positively (58% vs 39%), and more willing to be vaccinated (86% vs 39%;

Increasing HPV Vaccination in a Network of Pediatric Clinics using a Multi-component Approach

Background: Despite continued public health efforts to increase human papillomavirus (HPV) vaccination among adolescents, initiation remains below the level needed to reach the Healthy People 2020 goal of 80% series completion by age 13. Methods: We developed, implemented, and evaluated a multi-component program that used evidence-based strategies to increase HPV vaccine initiation in a network of 51 pediatric clinics in Houston, Texas. Our target populations were the clinic network, healthcare providers, male and female patients ages 11-17, and their parents. The program, called the Adolescent Vaccination Program (AVP), was conducted from March 2016 through March 2019 and contained strategies to increase vaccination including: HPV immunization champions; provider assessment and feedback; provider continuing education; provider reminders; and patient reminders. We used a single group pre/post design with an external comparison – NIS-Teen. Our primary outcome was initiation of the HPV vaccine based on the electronic health record. We used interrupted time series analysis (ITSA) to measure change in initiation over time. We calculated monthly, quarterly, and annual rates of initiation for each physician, clinic, and the network. We examined patterns of initiation by patient age, sex, race/ethnicity, and type of insurance. Results: By the end of the project, the 51 clinics averaged 77.4% initiation. Rates increased annually from September 2015 through March 2019. ITSA analysis over 75 months showed an increase in vaccine initiation of 0.396% per month from the introduction of the program in March 2016. Average individual clinic improvement was 0.37% per month ranging from -0.04% to 0.68% through March 2019. Data for the 11-12 year olds, the target age group for initiating the vaccine, showed a greater percentage increase (54.2%) compared with the 13-17 year olds (29.6%). Hispanics and African Americans had the highest initiation rates in all years while non-Hispanic whites had the lowest. Families without insurance had the lowest rates while those with Medicaid/Medicare had the highest. Conclusions: We observed a secular trend upward in both the network and NIS-Teen data; however, the network showed a steeper increase. The AVP is a promising program of strategies to increase HPV vaccination in a clinic setting

Improving Human Papillomavirus-Related Knowledge and Attitudes Among Ethnically Diverse Young Adults

Purpose: To make baseline comparisons and evaluate the efficacy of an intervention designed to improve human papillomavirus (HPV) and HPV vaccine awareness, knowledge, and attitudes among ethnically diverse participants. Methods: Design: Pre- and post-intervention surveys. Setting: An urban, Hispanic-Serving South Florida university. Subjects: Three hundred eighty-seven diverse college students attending a gender studies course. Intervention: Students received a brief educational message designed to improve HPV-related knowledge and attitudes. Baseline and follow-up survey data were collected. Measures: Outcome measures included baseline and follow-up awareness of HPV, perceived knowledge of HPV and HPV vaccination, measured knowledge score, vaccine attitudes, and doses of HPV vaccine received. Analysis: Chi-square, analysis of covariance (ANCOVA), and Wilcoxon rank-sum tests were used to compare baseline differences and evaluate the efficacy of the intervention. Results: Hispanic participants had more positive attitudes toward HPV vaccination (62% vs. 44%, p=0.009) and were more willing to become vaccinated (66% vs. 46%, p=0.02) than non-Hispanic participants at baseline. Hispanic women (48%) were more likely to have initiated HPV vaccination than Hispanic men (27%, p=0.006). At baseline, only 30% of participants scored ≥4/7 points in knowledge. Participants' HPV knowledge improved by 41% after the intervention, with no difference by ethnicity in the post-intervention score. Conclusion: The intervention was useful in improving HPV-related knowledge and attitudes among diverse college students. Future studies should examine barriers to vaccination among ethnic minorities

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
