Parent Perception of Provider Interactions Influences HPV Vaccination Status of Adolescent Females

Clinician communication strategies associated with increased uptake of the human papillomavirus (HPV) vaccine: A systematic review

Human papillomavirus (HPV) is currently linked to almost 35,000 new cases of cancer in women and men each year in the United States. Gardasil-9 (Merck & Company), the only HPV vaccine now available in the United States, is nearly 100% effective at preventing precancers caused by oncogenic HPV types. In the United States, however, only about one half of adolescents are up to date with HPV vaccination. It is well known that health care clinicians' recommendations play a significant role in parents' decisions regarding HPV vaccination. A growing body of literature examines specific communication strategies for promoting uptake of the HPV vaccine. A comprehensive review of the evidence for each of these strategies is needed. The authors searched the PubMed, EMBASE, Cochrane Central Register of Controlled Trials, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, and Web of Science Complete databases for original articles with a defined clinician communication strategy and an outcome of HPV vaccine uptake or intention to vaccinate (PROSPERO registry no. CRD42020107602). In total, 46 studies were included. The authors identified two main strategies with strong evidence supporting their positive impact on vaccine uptake: strong recommendation and presumptive recommendation. Determinations about a causal relationship were limited by the small numbers of randomized controlled trials. There is also opportunity for more research to determine the effects of motivational interviewing and cancer-prevention messaging.

Pre-implementation evaluation for an HPV vaccine provider communication intervention among primary care clinics

OBJECTIVES

Interventions to improve health care provider communication about HPV vaccination can increase vaccine acceptance. Our objectives were to (1) identify clinics in locations with high HPV-associated cancer and low HPV-vaccination rates that would potentially benefit from dissemination of a proposed HPV Provider Communication intervention and (2) use qualitative interviews and a dissemination and implementation framework to assess readiness for change and fit of the HPV Provider Communication intervention to the context of these clinics.

METHODS

Local HPV-associated cancer and HPV vaccination rates were assigned to Practice-Based Research Network clinics using data from the Colorado Central Cancer Registry, the Colorado Immunization Information System, and the American Community Survey. Staff from 38 clinics located in areas with high numbers of adolescents not up-to-date for HPV vaccine and high rates of HPV-associated cancers were recruited for qualitative interviews. Interview questions used the Promoting Action on Research Implementation in Health Services (PARIHS) conceptual framework and addressed the proposed intervention, current vaccination practices and prior quality improvement (QI) experience.

RESULTS

Twenty-seven interviews were completed with clinicians, clinic managers, and other staff across 17 clinics (9 pediatric, 5 family medicine, 3 public/school-based health). Most clinics had some prior QI experience and there were few thematic differences between sites with more or less foundation for QI/immunization work. Participants were motivated to improve the health of their patients and valued both guidelines and local experience as important evidence to consider adopting an intervention. Interviewees were more interested in implementing the proposed intervention if it aligned with existing priorities and fit within clinic workflows. Facilitation needs included adequate time and external facilitation support for data tracking and analysis.

CONCLUSIONS

Qualitative interviews to understand clinic context and fit of an HPV Provider Communication intervention can inform implementation in settings with the highest potential for clinical impact.

Balancing Between Being Proactive and Neutral: School Nurses' Experiences of Offering Human Papilloma Virus Vaccination to Girls

The aim of this study was to describe the experiences of Swedish school nurses when they offered the human papilloma virus (HPV) vaccination to girls aged 10-12 years. Four focus groups with a total of 17 school nurses were conducted and analyzed using inductive content analysis. The results showed that the school nurses were balancing between keeping a neutral role and the need to increase the uptake of the HPV vaccination. They described the consent forms and information that they gave the girls and their parents to help them make an informed decision about the vaccination. There were also ethical and moral dilemmas that arose with regard to the HPV vaccinations. Our findings demonstrate the need to provide school nurses with clear guidelines and support, so they can play an active role in interacting with the girls and their parents when they offer the HPV vaccination.

Disparities in Healthcare Providers' Recommendation of HPV Vaccination for U.S. Adolescents: A Systematic Review

Infrequent provider recommendations continue to be a key barrier to human papillomavirus (HPV) vaccination, including among adolescents at higher risk for future HPV cancers. To inform future interventions, we sought to characterize disparities in health care providers' HPV vaccine recommendation for U.S. adolescents. We systematically reviewed studies published in 2012-2019 that assessed provider HPV vaccine recommendations for adolescents aged 9-17. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we identified 52 eligible studies and used a standardized abstraction form to assess recommendation prevalence by adolescent demographic characteristics. Studies consistently found that fewer parents of boys than girls reported receiving HPV vaccine recommendations (14 studies, range of difference: -11 to -35 percentage points). Studies also found fewer recommendations for adolescents who were younger (2 studies, -3% to -12% points), non-White (3 studies, -5% to -7% points, females only), lower income (3 studies, -1% to -8% points), or uninsured (1 study, -21% points, males only). Studies identified geographic disparities in southern and rural areas. In conclusion, findings from this systematic review identify disparities in HPV vaccine recommendation that may contribute to suboptimal vaccine uptake. Efforts to improve providers' HPV vaccine communication should focus on increasing recommendation consistency, especially for lower-income, non-White, and rural adolescents.

Changes in Strength of Recommendation and Perceived Barriers to Human Papillomavirus Vaccination: Longitudinal Analysis of Primary Care Physicians, 2008-2018

OBJECTIVES

To evaluate among pediatricians and family physicians human papillomavirus (HPV) vaccination recommendation practices for 11- to 12-year-old youth; report parental refusal/deferral of HPV vaccination; and report barriers to HPV vaccination changed over time.

STUDY DESIGN

We surveyed nationally representative networks of pediatricians and family physicians in 2008, 2010, 2013-2014, and 2018. Male vaccination questions were not asked in 2008; barriers and parental vaccine refusal questions were not asked in 2010.

RESULTS

Response rates were 80% in 2008 (680/848), 72% in 2010 (609/842), 70% in 2013-2014 (582/829), and 65% in 2018 (588/908). The proportion of physicians strongly recommending HPV vaccination for 11- to 12-year-old patients increased from 53% in 2008 to 79% in 2018 for female patients and from 48% in 2014 to 76% in 2018 for male patients (both P < .0001). The proportion of physicians indicating ≥50% of parents refused/deferred HPV vaccination remained steady for female patients (24% in 2008 vs 22% in 2018, P = .40) and decreased for male patients (42% in 2014 vs 28% in 2018, P < .001). Physician barriers to providing HPV vaccination were rare and decreased over time. Increasing numbers of physicians reported perceived parental barriers of vaccine safety concerns (5% "major barrier" in 2008 vs 35% in 2018, P < .0001) and moral/religious concerns (5% in 2008 vs 25% in 2018, P < .0001).

CONCLUSIONS

Between 2008 and 2018, more primary care physicians reported recommending HPV vaccination for adolescents, fewer reported barriers, and more physicians reported parents who had vaccine safety or moral/religious concerns.

Burden and Prevention of HPV. Knowledge, Practices and Attitude Assessment Among Pre-Adolescents and their Parents in Italy

Despite infections due to HPV nowadays represent the most common sexually transmitted diseases worldwide with recognized effective and safe preventive strategies, knowledge, attitudes; however, awareness on HPV is considerably low. The present study has two main objectives: 1. To conduct a literature review to analyze the evolution of preventive tools, the complexity of the vaccine choice process, and the challenges posed by HPV vaccine hesitancy and refusal among pre-adolescents and their parents; 2. To assess knowledge, practices and attitudes toward HPV infection and vaccination in a sample of Italian pre-adolescents and their parents. The observational study was carried out through the use of two anonymous and self-administered pre- and post-intervention questionnaires dedicated to the target populations. Between the administrations of the pre- and post-intervention questionnaires, an educational intervention on HPV infection and related diseases, and prevention strategies was conducted. All participants demonstrated suboptimal knowledge and positive attitudes in the pre-intervention questionnaire. Higher levels of knowledge and attitudes were observed among pre-adolescents thatused social networks and had heard of sexually transmitted diseases at home/school/physician and from parents and also who had heard of HPV from General Practitioners, Gynecologists, family members and newspapers. A significant increase in HPV vaccination awareness was observed among pre-adolescents after the educational sessions. Health education programs aimed at increasing knowledge, attitudes and awareness on HPV are needed to implement the outcomes of HPV immunization programs, especially if supported by the physicians involved in counselling and recommendation processes.

Resources for assessing parents' vaccine hesitancy: a systematic review of the literature

The concept of Vaccine Hesitancy has begun to appear in the scientific landscape, referring to the reluctance of a growing proportion of people to accept the vaccination offer. A variety of factors were identified as being associated with vaccine hesitancy but there was no universal algorithm and currently there aren’t any established metrics to assess either the presence or impact of vaccine hesitancy. The aim of this study was to systematically review the published questionnaires evaluating parental vaccine hesitancy, to highlight the differences among these surveys and offer a general overview on this matter. This study offers a deeper perspective on the available questionnaires, helping future researches to identify the most suitable one according to their own aim and study setting.

Suboptimal uptake of human papillomavirus (HPV) vaccine in survivors of childhood and adolescent and young adult (AYA) cancer

PURPOSE

To estimate the population-based incidence of HPV vaccination after childhood cancer.

METHODS

Pediatric and young adult cancer survivors identified in the institutional Comprehensive Cancer Center registry were linked to the North Carolina Immunization Registry (NCIR). Initiation and completion of any HPV vaccine was evaluated in survivors born between 1984 and 2002 with an NCIR record by December 2014. Descriptive statistics and Kaplan-Meier estimates of cumulative incidence were stratified by sex and age at eligibility for vaccine. Cox proportional hazards were conducted and stratified by sex.

RESULTS

Among 879 (n = 428 female; n = 451 male) study-eligible cancer survivors without prior HPV vaccination (n = 501 < 18 years, n = 378 ≥ 18 years at the time of eligibility), the cumulative incidence of HPV vaccine initiation following cancer therapy was 48.1% among females at 8.2 years and 29.2% among males at 5.0 years after vaccine eligibility among those < 18 years, and 6.2% among females at 8.1 years and 2.0% among males at 4.2 years after vaccine eligibility among those ≥ 18 years. Among those who initiated vaccination, 53% of females and 43% of males completed a 3-dose series. Younger age at cancer diagnosis (≤ 10 and 11-14 years vs. ≥ 15 years) and shorter interval from diagnosis to vaccine eligibility were more likely to initiate vaccination in models adjusted for age at eligibility, race/ethnicity, cancer type, relapse, and transplant.

CONCLUSIONS

Despite the benefit of a cancer prevention strategy, cancer survivors are sub-optimally vaccinated against HPV.

IMPLICATIONS FOR CANCER SURVIVORS

Immunization registries can help oncologists and primary care providers identify gaps in vaccination and target HPV vaccine delivery in survivors.

HPV vaccination, knowledge, and attitudes among young cervical cancer survivors in the Deep South

INTRODUCTION

Although FDA approved for over 10 years, uptake of the human papillomavirus (HPV) vaccination has been slow, particularly among states in the Deep South with high cervical cancer incidence and mortality. The purpose of this study was to explore variables associated with cervical cancer among survivors who were age-eligible for the HPV vaccine and to assess HPV vaccination history, barriers, perceptions, and other associated behaviors within this cohort.

METHODS

A mixed methods strategy was used for the study, first identifying eligible cervical cancer survivors from our institution and abstracting demographic and clinicopathologic medical record data. Twenty-three participants from this cohort then completed semi-structured qualitative telephone interviews regarding HPV vaccination participation, knowledge, and attitudes. Interviews were audio-recorded, transcribed, and analyzed using thematic content analysis.

RESULTS

Of the 464 cervical cancer patients treated at our institution from 2011 to 2016, 137 (30%) were under age 40 at diagnosis. Seventy-seven women with invasive disease were identified (median age = 33 years), and 56% had been seen by a gynecologist within 5 years of diagnosis. Forty-six of these women met eligibility criteria for inclusion in the qualitative interview, of which 23 successfully completed (response rate = 50%). Of those interviewed, the majority (84%) reported current access to regular medical care. While 90.9% did not receive any doses of HPV vaccination, 78.3% stated they likely would have been vaccinated if it had it been recommended. Four major themes were identified within the interviews: HPV knowledge, vaccine acceptability, healthcare engagement, and provider communication.

CONCLUSIONS

Qualitative interviews revealed significant missed opportunities for prevention since most participants stated they would have been vaccinated if given the option. Substantial gaps in knowledge and mixed understanding HPV's association with cervical cancer were observed, demonstrating potential missed opportunities for education and communication between providers of multiple specialties and their patients.

Evaluation of the Implementation of a Multicomponent Intervention to Improve Health Care Provider Communication About Human Papillomavirus Vaccination

OBJECTIVE

To evaluate the relative use, usefulness, and facilitators and barriers to use as perceived by providers of 5 different components in a human papillomavirus vaccine communication intervention-which was found to be effective at improving human papillomavirus vaccination rates.

METHODS

Four serial surveys of 108 providers (doctor of medicine, nurse practitioner, or doctor of osteopathic medicine) from intervention clinics involved in the study assessed the use and usefulness of the 5 communication intervention components during a 12-month period.

RESULTS

Survey response rates were 79% to 86%. The fact sheet (64%-77%) and motivational interviewing techniques (MI; 86%) were the most used components-use was sustained during the 12-month period. These components also were perceived as somewhat or very useful by most providers, and this perceived usefulness increased over time (very or somewhat useful at end of study, 97% fact sheet, 98% MI, respectively). Although fewer providers reported using the Web site (15%-42%), or disease images (6%-17%), when these were used, most providers (67%-87%) felt they were somewhat or very useful. The decision aid was not used frequently (17%-41% of providers), and 43% of providers felt it was not very or not at all useful. Facilitators and barriers were identified for each component. The fact sheet and MI were perceived as the easiest to integrate into the clinic workflow.

CONCLUSIONS

The fact sheet and MI were the most used and most useful intervention components. Both were easy to integrate into clinic workflow, and their use was sustained over time. Dissemination of similar interventions in the future should focus on these 2 specific components.

Development and Evaluation of a Social Media Health Intervention to Improve Adolescents' Knowledge About and Vaccination Against the Human Papillomavirus

This study describes the formative research, execution, and evaluation of a social media health intervention to improve adolescents’ knowledge about and vaccination against human papillomavirus (HPV). Based on the results from formative focus groups with adolescents (N = 38) to determine intervention feasibility, parameters, and message preferences, we developed and conducted a pretest/posttest evaluation of a 3-month social media health intervention for adolescents who had not completed the HPV vaccine series (N = 108). Results revealed that adolescents who fully engaged with the intervention improved in their knowledge compared with a control group, and many were also likely to have interpersonal discussions with others about what they learned. Adolescents are generally interested in receiving information about HPV and the vaccine, along with other relevant health information, through social media channels if messages are considered interesting, their privacy is protected, and the source is credible.

Parents' uptake of human papillomavirus vaccines for their children: a systematic review and meta-analysis of observational studies

OBJECTIVE

To examine factors associated with parents' uptake of human papillomavirus (HPV) vaccines for their children.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Cochrane Library, AIDSLINE, CINAHL, EMBASE, PsycINFO, Social Sciences Abstracts, Ovid MEDLINE, Scholars Portal, Social Sciences Citation Index and Dissertation Abstracts International from inception through November 2017.

METHODS

We included studies that sampled parents and assessed uptake of HPV vaccines for their children (≤18 years) and/or sociodemographics, knowledge, attitudes or other factors associated with uptake. Study risk of bias was assessed using the Effective Public Health Practice Project tool. We pooled data using random-effects meta-analysis and conducted moderation analyses to examine variance in uptake by sex of child and parent.

RESULTS

Seventy-nine studies on 840 838 parents across 15 countries were included. The pooled proportion of parents' uptake of HPV vaccines for their children was 41.5% (range: 0.7%-92.8%), twofold higher for girls (46.5%) than for boys (20.3%). In the meta-analysis of 62 studies, physician recommendation (r=0.46 (95% CI 0.34 to 0.56)) had the greatest influence on parents' uptake, followed by HPV vaccine safety concerns (r=-0.31 (95% CI -0.41 to -0.16)), routine child preventive check-up, past 12 months (r=0.22 (95% CI 0.11 to 0.33)) and parents' belief in vaccines (r=0.19 (95% CI 0.08 to 0.29)). Health insurance-covered HPV vaccination (r=0.16 (95% CI 0.04 to 0.29)) and lower out-of-pocket cost (r=-0.15 (95% CI -0.22 to -0.07)) had significant effects on uptake. We found significant moderator effects for sex of child.

CONCLUSIONS

Findings indicate suboptimal levels of HPV vaccine uptake, twofold lower among boys, that may be improved by increasing physician recommendations, addressing parental safety concerns and promoting parents' positive beliefs about vaccines, in addition to expanding insurance coverage and reducing out-of-pocket costs. Limitations of this meta-analysis include the lack of intervention studies and high risk of bias in most studies reviewed. Further studies should disaggregate HPV vaccine uptake by sex of child and parent.

Human Papillomavirus Vaccination: Narrative Review of Studies on How Providers' Vaccine Communication Affects Attitudes and Uptake

The burden of human papillomavirus (HPV) infections is substantial, causing thousands of cancers and deaths in the United States yearly. Safe and effective vaccines exist, yet remains underutilized, particularly among younger adolescents for whom the vaccine is targeted. Provider communication techniques are known to affect parents' and adolescents' acceptance of this vaccine. In this review, we examine the influence that provider communication techniques have on parental attitudes regarding HPV vaccine, as well as how those techniques affect vaccination uptake. We explore the limited literature that has directly measured the influence of provider communication techniques on parental attitudes, which suggests that the strength of a provider recommendation strongly influences parents' perceptions regarding the safety of HPV vaccine, and that brief recommendations might be best for parents without significant concerns. We also review the literature regarding the use of so-called 'presumptive' recommendations, and how these types of recommendations are associated with increased HPV vaccine uptake. Finally, we present new information regarding the use of motivational interviewing as a provider communication technique to improve vaccination uptake, particularly among vaccine-hesitant parents. We close with suggestions for 'best practices' that include using brief, strong, unambiguous language to introduce the HPV vaccine, followed by more nuanced communication techniques, such as motivational interviewing, when encountering resistance.

Characterizing safety-net providers' HPV vaccine recommendations to undecided parents: A pilot study

OBJECTIVE

Although provider recommendation is a key predictor of HPV vaccination, how providers verbalize recommendations particularly strong ones is unknown. We developed a tool to describe strength and content of provider recommendations.

METHODS

We used electronic health records to identify unvaccinated adolescents with appointments at six safety-net clinics in Dallas, Texas. Clinic visit audio-recordings were qualitatively analyzed to identify provider recommendation types (presumptive vs. participatory introduction; strong vs. weak), describe content communicated, and explore patterns between recommendation type and vaccination.

RESULTS

We analyzed 43 audio-recorded discussions between parents and 12 providers. Most providers used a participatory introduction (42 discussions) and made weak recommendations (24 discussions) by using passive voice or adding a qualification (e.g., not school required). Few providers (11 discussions) gave strong recommendations (clear, personally-owned endorsement). HPV vaccination was lowest for those receiving only weak recommendations and highest when providers coupled the recommendation with an adjacent rationale.

CONCLUSION

Our new tool provides initial evidence of how providers undercut their recommendations through qualifications or support them with a rationale. Most providers gave weak HPV vaccine recommendations and used a participatory introduction.

PRACTICE IMPLICATIONS

Providers would benefit from communication skills training on how to make explicit recommendations with an evidence-based rationale.

Student HPV vaccine attitudes and vaccine completion by education level

PURPOSE

We describe HPV vaccine attitudes among students of different education levels.

METHODS

High school, college, and graduate-level health care professional students were surveyed regarding HPV vaccine knowledge, attitudes, and receipt. Relationships between categorical variables were analyzed using chi-square tests of independence and z-tests for proportions. Means for quantitative variables were compared using t-tests and one-way analysis of variance.

RESULTS

57% and 42% of the 889 students reported starting and completing HPV vaccine series, respectively, with no statistical difference by education level. 61% of students who reported receiving a provider recommendation had completed the series, compared to 6% of those who did not receive recommendation (p<0.001). The belief that HPV vaccine prevents cancer was strongly associated with vaccine completion (p=0.003).

CONCLUSION

HPV vaccine coverage rates remain suboptimal. Future interventions should focus on improving provider recommendation and patient belief that HPV vaccine prevents cancer.
