Oral health care professionals recommending and administering the HPV vaccine: Understanding the strengths and assessing the barriers

What cancers explain the growing rural-urban gap in human papillomavirus-associated cancer incidence?

PURPOSE

Human papillomavirus (HPV) can cause cancers of the genital system, anus/rectum, and oropharynx. Prior research showed that HPV-associated cancer incidence was rising faster in nonmetro than in metro populations. Our study identified which cancers contributed to the widening disparity.

METHODS

Representing ∼93% of all cancers in the United States, we analyzed data from the North American Association of Central Cancer Registries (2000-2019). Restricting the analysis to HPV-associated cancers, we compared 5-year average age-adjusted incidence rates (per 100,000 population) for nonmetropolitan (Rural-Urban Continuum Codes 4-9) and metropolitan populations, by sex and cancer site. To quantify the rural-urban gap, we calculated rate ratios and absolute differences of incidence trends.

RESULTS

Although incidence was similar in 2000-2004 (nonmetropolitan = 9.9; metropolitan = 9.9), incidence in 2015-2019 was significantly higher in nonmetropolitan (12.3) than metropolitan (11.1) populations. The gap was widest for cervical cancers (females) in 2015-2019 (1.0 case per 100,000) but grew the most since 2000-2004 in oropharyngeal cancers among males (+1.1 cases per 100,000). The nonmetropolitan rate ratios for females (RR = 1.15, 95% C.I. = 1.13, 1.17) and males (RR = 1.07, 95% C.I. = 1.05, 1.09) in 2015-2019 were higher than the respective RRs for all other years. Since 2000, the nonmetropolitan disparity has significantly grown for anal and cervical cancers in females, and oropharyngeal cancers in both sexes.

DISCUSSION

Although preventable, nonmetropolitan Americans have shouldered a growing burden of HPV-associated cancers. To address these cervical, anal, and oropharyngeal cancer disparities, it is imperative that HPV vaccination programs are effectively implemented at scale.

A scoping review of evidence on routine cervical cancer screening in South Asia: investigating factors affecting adoption and implementation

NEED: Cervical cancer is a major global public health issue, particularly affecting low and middle-income countries, distinctly in the South Asian region. This geographical region lacks a well-organized routine cervical screening program. Consequently, this scoping review aimed to investigate the evidence on factors influencing the adoption and implementation of routine cervical cancer screening in South Asia.

METHODS

Adopting the "Arksey and O'Malley and Levac et al." methodology, databases such as PubMed, CINAHL, Web of Science, and Scopus were scrutinized in the pursuit of relevant studies. Subsequently, the collected data were synthesized by adopting the Consolidated Framework for Implementation Research (CFIR) model.

RESULTS

A total of 837 records were initially identified and screened for eligibility, including 55 studies. The successful adoption and implementation of cervical cancer screening in South Asia encounter numerous obstacles within the health system, including the absence of a comprehensive program protocol for screening, inadequate health infrastructure, and the presence of multiple sociocultural factors, such as social stigma, low levels of education, and concerns related to modesty.

CONCLUSION

To optimize adoption and implementation, it is imperative to construct a customized policy framework that incorporates a risk communication strategy tailored to the specific contexts of these nations. Drawing insights from the experiences of South Asian countries in executing cervical cancer screening programs can inform the formulation of policies for similar healthcare initiatives aimed at facilitating the expansion of HPV vaccination efforts.

Perceived barriers and facilitators to HPV vaccination: Insights from focus groups with unvaccinated mid-adults in a U.S. medically underserved area

Shared clinical decision-making (SCDM) about HPV vaccination has been recommended for U.S. mid-adults aged 27-45 since 2019. To explore barriers and facilitators to HPV vaccination in this population, we conducted 14 virtual focus groups with 86 unvaccinated mid-adults (34 men and 52 women) in California's medically underserved Inland Empire between September 2020 and January 2021. We systematically analyzed the focus group data using the rigorous and accelerated data reduction (RADaR) technique to identify key themes. Identified barriers included: lack of awareness, vaccine hesitancy, and perceived unaffordability (cited in 14 groups); lack of healthcare provider communication and insufficient time (13 groups); fear of moral judgment (12 groups); lack of motivation and information needs (10 groups); and lack of reliable transportation and foregone care during the COVID-19 pandemic (3 groups). Proposed facilitators included: tailored HPV vaccine information for mid-adults, cost mitigation, and improved vaccine accessibility (12 groups); healthcare provider-initiated conversations (6 groups); and vaccine reminders (4 groups). These findings highlight challenges to HPV vaccination among U.S. mid-adults eligible for SCDM and point to actionable strategies for improvement. Specifically, tailored educational interventions, decision-making tools for pharmacists, and integrating HPV vaccination into other healthcare encounters may enhance vaccination efforts in areas with limited primary care resources.

Identifying the Gaps in Human Papillomavirus (HPV) Vaccine Uptake: An Exploratory Factor Analysis of Adults in Tennessee

Background: Human papillomavirus (HPV) remains the most prevalent sexually transmitted infection in the United States (U.S.). By the age of 45, over 80% of Americans will contract HPV, which creates a significant public health concern. Despite the availability of effective vaccines, low vaccination uptake continues to be a challenge, particularly in Tennessee. Additionally, the Advisory Committee on Immunization Practices (ACIP) recently expanded recommendations for HPV vaccine usage to include adults aged 27-45, suggesting a population with the potential to experience a gap in preventative care. To understand the underlying factors that may hinder Tennesseans from receiving the HPV vaccine, we conducted a cross-sectional survey from 29 June to 17 August 2023 among adults aged 18 to 45 in Tennessee. The survey was developed and informed by a scoping review regarding the various constructs and frameworks used in vaccine hesitancy and our previous qualitative work. Using theory-based instruments and previous qualitative data, this study aimed to determine the underlying factors that may hinder Tennesseans from receiving the HPV vaccine, focusing on those adults within the recently approved age range of 27-45 years old. Methods: An Exploratory Factor Analysis of 2011 participants ultimately included five factors, which explain 70.3% of the variability. These were Benefits/Trust, Perceived Susceptibility, Attitude/Behavioral Control, Perceived Barriers, and Perceived Severity. All Cronbach alphas were greater than 0.80, indicating that each factor was reliable. Results: When stratifying by various demographics, our analysis found that race emerged as a significant factor (p = 0.002), while the interaction of race and vaccination status was not significant (p = 0.753). Black respondents had significantly lower levels of Benefits/Trust than White (p < 0.001) and Asian respondents (p = 0.030), with no significant differences between White and Asian respondents. Conclusions: These findings underscore the importance of researchers, healthcare professionals, public health officials, and policymakers in addressing these demographic differences to effectively increase vaccination rates and reduce HPV-associated cancer risks in Tennessee. Further studies are needed for targeted interventions to address these disparities.

Knowledge, attitude and perception of Italian dental students toward HPV-related oropharyngeal cancer and vaccination: a cross-sectional study

BACKGROUND

Human papillomavirus (HPV) infection is a leading cause of oropharyngeal squamous cell cancer (OPSCC). This study aimed to carry out a Knowledge, Attitude and Perception survey on HPV infection, HPV+ OPSCC, and HPV vaccination among Italian dental students.

METHODS

Through an online self-administered questionnaire consisting of 82 questions, data on dental students' sociodemographic characteristics, knowledge, attitudes and perceptions concerning HPV+ OPSCC, infection and vaccination were acquired. A statistical analysis, based on their year of attendance (early career, from 1st to 3rd year vs. late career, from 4th to 6th year) was also conducted.

RESULTS

A total of 412 dental students completed the questionnaire. Knowledge of HPV+ OPSCC was reported by 61% of early-career students and 73% of late-career students, with high awareness of the HPV-OPSCC correlation in both groups (85% vs. 89%, respectively). The percentage of correct responses regarding HPV infection knowledge was 61% for early-career and 73% for late-career students, while vaccine knowledge was 70% and 78%, respectively. Over 90% of students acknowledged the dentist's role in educating patients about HPV and OPSCC, and attitudes toward discussing HPV and vaccination were positive. However, only about half would recommend the vaccine to either gender. Statistically significant differences were found between early- and late-career groups across all knowledge sections (p < 0.001), while no significant differences emerged for perception (p = 0.076) or attitude (p = 0.147).

CONCLUSIONS

The study reveals encouraging results but highlights significant gaps in dental students' knowledge, perceptions, and attitudes toward HPV+ OPSCC, infection, and vaccination. Addressing these gaps through targeted education and training in dental curricula could improve HPV prevention awareness and patient education, ultimately enhancing public health outcomes.

Retrospective study of a pilot program focused on educating dental patients on human papillomavirus and vaccination in a hospital setting

INTRODUCTION

Human papillomavirus (HPV) is an epidemic currently affecting 80 million people in the United States. The HPV virus can be passed from one person to another via sexual intercourse, oral sex, open mouth kissing and skin-to-skin contact. In some cases, the infection is not eliminated by the immune system and can cause cancer of the head and neck, cervix, anus, and genitals. There has been a rise in oropharyngeal cancer (OPC) associated with HPV, which can be missed on conventional dental screening examinations. Dentists should engage in promoting HPV vaccination as a primary measure for OPC prevention. The goal of this HPV pilot program was to educate and offer same day HPV vaccination to dental patients by using a multidisciplinary approach in a hospital setting.

METHODS

Patients 18 through 26 years of age who presented to the Erie County Medical Center's dental clinic were approached and educated on HPV. Eligible patients received a direct recommendation for the HPV vaccine. Those interested in same day vaccination were referred to the division of infectious diseases' YOU Center for Wellness. A retrospective chart review was completed for patients who were HPV educated from March 5, 2020, through December 15, 2021. Charts were evaluated for age, sex, race, ethnicity, reason for visit, HPV vaccine referral, and HPV vaccine administration.

RESULTS

326 patients were included in the chart review. The prominent sex, race, and ethnicity were male, Black or African American, and non-Hispanic origin. The median age was 23. Most patients presented to the dental clinic for an emergency visit and were not previously vaccinated against HPV. 110 patients were unvaccinated, and 44 patients were referred to the division of infectious disease for same day vaccination. Of these 44, 24 patients initiated the vaccination process. Five patients received all three doses, three patients received two doses, and 16 patients received one dose.

CONCLUSION

This pilot program successfully vaccinated 24 patients with at least a single dose of the HPV vaccine. This multidisciplinary model can be implemented in other health care settings.

Case-finding for HPV vaccination eligibility within a dental office with concurrent development of a dialogue tool

Background

Human papillomavirus (HPV) immunization can prevent cancers, but uptake has been incomplete (and worse with the COVID-19 pandemic). Dental clinicians already screen for oral cancers, many of which are caused by HPV, and could identify vaccination candidates, but this requires a case-finding strategy.

Objective

The purpose of this study was (1) to develop and test a case-finding approach to identify patients who were candidates for HPV vaccinations, (2) to test an HPV vaccination intervention by dental professionals on vaccination uptake.

Methods

Design: Prospective, non-randomized feasibility case finding study with a 4-week enrollment period and a 6 week follow up period in general dental offices.Setting: Two general and non-commercial dentistry offices in Edmonton, Alberta Canada.Subjects: Consecutive scheduled (non-emergent) patients who met the Health Canada criteria for HPV vaccination: immunocompetent males and females aged 9-45 years and those who are immunocompromised. Consent for the discussion was obtained from each subject or parent.Intervention: Scheduled dental patients meeting the inclusion criteria were flagged by a research assistant who reviewed the appointment schedule each week for 4 weeks. For these subjects, dental clinicians (dentists and dental hygienists) used our Dental Dialogue Tool to discuss HPV vaccination and answer questions. Participating patients who consented to receive the HPV vaccine were given a prescription by the attending dentist and were directed to follow-up with a local pharmacy to have the vaccine administered. Each participant that was provided with an HPV prescription was contacted after 6 weeks to identify if they received the first dose of vaccine.Outcomes: Yield of our case-finding strategy and receipt of a patient's first HPV vaccine dose during 6 weeks post vaccine prescription.

Results

Our case-finding strategy assessed 656 scheduled patients over 4 weeks. From this screening,179 (a case-finding yield of 20.4 %), were candidates for HPV vaccine discussion. Forty-three of these 179 patients (24 %) were already vaccinated.. Two patients (1.1 %) did not consent to be spoken with and 134 (74.8 %) consented to the HPV vaccine discussion.. Forty-eight of 134 patients (35.8 %) of patients accepted a prescription from the dentist after speaking with the dental clinician. Ultimately, 8/48 (16 %) (patients received their first dose of the HPV vaccine by the 6 week of follow-up call. However, this is only 4.5 % (8/177) of those patients who did consent for the discussion of HPV cancers and vaccination from their dentist.

Conclusion

We demonstrated that case-finding for HPV vaccine candidates in general dental offices was feasible, with a reasonable yield. While the dental dialogue tool was described as a great resource to explain the facts and answer questions, very few patients were vaccinated after 6 weeks of follow-up. Further work is necessary to sharpen the intervention, perhaps including follow-up discussions with the dental clinicians.

Patient receptivity to receiving vaccinations in the dental clinic at a rural federally qualified health center

BACKGROUND

More than 28 million people in the United States visited their dentists but not a physician in 2018, yet only a few states allow dentists to administer vaccines to patients, and those vaccines are limited to influenza, COVID-19, and human papillomavirus.

METHODS

To assess the receptiveness of adult dental patients and caregivers of pediatric dental patients to receive necessary vaccines during their dental appointment, a survey was distributed to patients attending a dental visit at a rural federally qualified health center from June 28, 2021, through December 31, 2021.

RESULTS

Among the responses from 643 adult patients and 625 pediatric caregivers, approximately one-half (54.2% and 49.9%, respectively) reported being receptive to receiving vaccines in the dental clinic, with 28.5% and 21.8% not being receptive to vaccines, respectively. Primary language, age group, number of children, and primary care center all were associated significantly with reported likelihood of receiving vaccines (P < .05). The most reported concern about receiving vaccines at a dental clinic was a preference for their primary care physician to provide all vaccinations, according to 22.2% of adult patients and 39.8% of pediatric caregivers.

CONCLUSIONS

The authors' findings support efforts to administer vaccines during dental visits to improve immunization rates among adults and children. Ongoing communication with primary care physicians regarding administration of vaccines in the dental clinic could reduce concerns by adult patients and pediatric caregivers.

PRACTICAL IMPLICATIONS

Strategies and policies that establish protocols to ensure the safe and effective administration of vaccines in dental visits should be implemented and supported.

The relation between human papillomavirus (HPV) and oropharyngeal cancer: a review

Oropharyngeal squamous cell carcinomas (OPSCC) represent a major public health challenge. In 2020, the international agency for research on cancer (IARC) recorded 98,421 cases of OPSCC worldwide. Over the past decade, the epidemiological profile of patients with OPSCC has shifted, mainly due to a change in etiological factors. Previously, alcohol and tobacco were considered the primary contributors, but the human papillomavirus (HPV) is now recognized as the leading cause of these tumors. This study aimed to conduct a literature review on the relationship between OPSCC and HPV for the general practitioner. The review examined the primary clinical differences between HPV⁺ and HPV^- OPSCC, their prognosis and treatment. In addition, the various HPV diagnostic methods were analyzed. Although there is a vast amount of literature on HPV, this review is unique in its ability to present the key information in an organized and accessible way and enables healthcare professionals to gain a better understanding of the relationship between HPV and oropharyngeal cancer. This, in turn, can contribute to the prevention of various cancers caused by the HPV virus, including oropharyngeal cancer.

Engaging new partners in human papillomavirus (HPV) vaccine promotion: Considerations for training private practice dental professionals in HPV vaccine promotion

OBJECTIVES

With rates of the human papillomavirus (HPV) vaccination remaining low and rates of oropharyngeal cancer rising, engaging new partners to promote vaccination is necessary. We aimed to identify dental hygienists' and dentists' knowledge about HPV, the HPV vaccine, and preferences for continuing education.

METHODS

This mixed-methods study recruited dental hygienists and dentists working in private practice in Iowa to participate in a mailed cross-sectional survey (dental hygienists) and qualitative telephone interviews (dental hygienists and dentists). Survey and interview topics included existing knowledge about HPV vaccination, HPV vaccination promotion efforts, barriers to HPV vaccine promotion, and preferences for continuing education (CE).

RESULTS

We received 470 surveys from dental hygienists (response rate = 22.6%) and interviewed 19 dental hygienists and 20 dentists. Vaccine efficacy and safety, along with communication strategies, were key topics of interest for CE. Dental hygienists' most commonly identified barriers were lack of knowledge (67%) and low comfort levels (42%).

CONCLUSIONS

Knowledge was identified as a key barrier to providing a strong recommendation for HPV vaccination and convenience was the most important factor to consider for any future CE. Our team is in the process of designing a CE course based on this information to help dental professionals effectively engage in HPV vaccine promotion in their practices.

Evidence on factors influencing HPV vaccine implementation in South Asia: A scoping review

Cervical cancer is a significant public health concern globally, with low and middle-income countries bearing the highest burden, specifically the South Asian region. Therefore, the current scoping review aimed to highlight the factors influencing the implementation of human papillomavirus (HPV) vaccination in South Asia. Adopting the 'Arksey and O'Malley and Levac et al.' methodology, multiple electronic databases were searched to identify relevant records. The results were narratively synthesised and discussed, adopting the Consolidated Framework for Implementation Research (CFIR) model. We identified 527 records, which were assessed for eligibility based on title, abstract, and full text by three reviewers, followed by data extraction of 29 studies included for analysis in the review. Implementing HPV vaccination programs in South Asia faces various challenges, such as economic, health system, financial, health literacy, and sociocultural factors that hinder their successful implementation. To successfully implement the vaccine, a tailored risk communication strategy is necessary for these countries. Knowledge gained from the experience of South Asian nations in implementing the HPV vaccine can assist in policymaking in similar healthcare for advancing the implementation of HPV vaccination.

A clinician’s dilemma: what should be communicated to women with oncogenic genital HPV and their partners regarding the risk of oral viral transmission?

Head and neck cancer, the sixth most common cancer worldwide, account for about 1 out of 20 malignant tumors. In recent years a reduction in the incidence of cervical cancer, but a concomitant major increase in the incidence of HPV-mediated oropharyngeal cancer caused by orogenital HPV transmission has been observed. Consequently, in wealthy countries oropharyngeal squamous-cell carcinomas (OPSCC) is now the most frequent HPV-related cancer, having overtaken cervical cancer. Without effective medical interventions, this incidence trend could continue for decades. As no specific precursor lesion has been consistently identified in the oral cavity and oropharynx, HPV vaccination is the logical intervention to successfully counteract also the rising incidence of OPSCCs. However, HPV vaccine uptake remains suboptimal, particularly in males, the population at higher risk of OPSCC. Alternative primary prevention measures, such as modifications in sexual behaviors, could be implemented based on knowledge of individual genital HPV status. Until recently, this information was not available at a population level, but the current gradual shift from cytology (Pap test) to primary HPV testing for cervical cancer screening is revealing the presence of oncogenic viral genotypes in millions of women. In the past, health authorities and professional organizations have not consistently recommended modifications in sexual behaviors to be adopted when a persistent high-risk HPV cervicovaginal infection was identified. However, given the above changing epidemiologic scenario and the recent availability of an immense amount of novel information on genital HPV infection, it is unclear whether patient counseling should change. The right of future partners to be informed of the risk could also be considered. However, any modification of the provided counseling should be based also on the actual likelihood of a beneficial effect on the incidence of HPV-associated oropharyngeal cancers. The risk is on one side to induce unjustified anxiety and provide ineffective instructions, on the other side to miss the opportunity to limit the spread of oral HPV infections. Thus, major health authorities and international gynecologic scientific societies should issue or update specific recommendations, also with the aim of preventing inconsistent health care professionals’ behaviors.

Leveraging teachable moments in cancer prevention by improving HPV vaccination in health professional students (HPS): A systematic review

Introduction

Vaccination against HPV is safe and effective in cancer prevention, yet vaccination uptake remains low. Strong recommendation of HPV vaccination by healthcare providers increases immunization rates, but gaps in knowledge persist surrounding HPV and HPV vaccination amongst health professional students (HPS). It is critical to educate HPS in all professions to maximize vaccination opportunities and increase vaccine uptake. The objective of this study is to evaluate evidence on HPV knowledge, vaccine uptake, and educational interventions in HPS to identify specific deficits to improve education.

Methods

A systematic literature search for articles on HPV vaccine uptake, knowledge, and educational interventions in HPS was performed in PubMed, Embase, Web of Science, CINAHL, and Scopus from January 1, 2006 – July 21, 2021. Included studies assessed HPS for HPV vaccine uptake, knowledge, counseling comfort, or educational interventions to increase HPV vaccine knowledge. Studies were screened for inclusion by 2 independent reviewers and evaluated for risk of bias. PRISMA guidelines for reporting were followed.

Results

Twenty-one unique articles met inclusion criteria and were included in the analysis. Of the studies included, 20 included knowledge, 11 included vaccine uptake, 8 included interventions, and 12 included counseling comfort. The students in the studies included medical (n=14), dental (n=7), dental hygiene (n=6), nursing (n=3), physician assistant (n=2), public health (n=1), and pharmacy (n=1). Across studies, HPV vaccine series initiation ranged from 34.6-70.3%, with 28.3-58.3% up to date on vaccination. Most students knew that HPV causes cervical cancer (99%), but fewer knew that HPV causes head and neck cancer (40-47%) and oropharyngeal cancer (45%). Educational interventions included team-based approaches and lectures, and improved outcomes including vaccine knowledge, vaccination schedule, and cancer knowledge. Medical students with lower knowledge of HPV were more hesitant to recommend vaccination at baseline but were more likely to recommend vaccination after an education session.

Discussion

Across HPS, inadequacies persist in HPV vaccine uptake, knowledge, and counseling comfort. It is critical to target vaccine uptake in this population and improve existing educational efforts to reduce preventable cancers. Institutions must prioritize HPV vaccine education to impact HPV related death.

Dental providers' perceptions of the feasibility and acceptability of implementing vaccine administration programs in dental settings: A qualitative study

OBJECTIVES

Involving dental offices in routine vaccinations could have a positive impact on public health. In this study, we assessed dental providers' attitudes and perceptions regarding implementing vaccination in dental settings.

METHODS

We performed semi-structured interviews with 31 dental providers (25 dentists and 6 dental hygienists) enrolled in the Western region of the National Dental Practice-Based Research Network as of June 28, 2021. Interviews were recorded and transcribed. We analyzed transcripts using deductive and inductive coding approaches.

RESULTS

We identified three main themes that captured the perceptions of dental practitioners regarding the feasibility of implementing vaccine administration in a dental setting: (1) dental practitioners perceive contributing to the public health mission of disease prevention as having high value, (2) dental practitioners face considerable complexity when deciding whether to implement vaccine administration, and (3) dental practitioners do not understand current laws and associated reimbursement models related to vaccine administration.

CONCLUSIONS

To make vaccination commonplace in dental practices, legal changes to allow dental practitioners to administer vaccines should be followed by concrete guidance and relevant trainings to help interested dental practitioners successfully implement vaccination programs in their clinical settings.

State-of-the-science concepts of HPV-related oropharyngeal squamous cell carcinoma: a comprehensive review

High-risk (HR) human papillomavirus (HPV) infection is recognized as a primary etiologic factor of anogenital cancers and more recently of a subgroup of oropharyngeal squamous cell carcinomas (OPSCC). The incidence of HPV-related OPSCC has increased dramatically in several developed countries in the past 3 decades and is currently the most common cancer caused by HR-HPV in the United States and Germany, surpassing cervical cancer. Consequently, the patient's demographic and clinicopathologic profile has shifted to nonsmoking and nondrinking younger men with higher schooling level and with a history of multiple oral sex partners. Patients with HPV-related OPSCC often show better treatment outcomes and higher survival rates than their HPV-unrelated counterparts, which has led to a change in tumor staging for HPV-related cases. HPV vaccination is emerging as an effective primary prevention strategy, and systematic screening of HPV DNA in blood and salivary oral rinse samples of HR patients is being examined to determine if it may provide a surveillance method and support early diagnosis of HPV-related OPSCC. In this context, a narrative review was conducted to provide an overview of the state-of-the-art of HPV-related OPSCC, including epidemiology, risk factors, clinicopathologic and molecular features, screening, prevention, management, and prognosis.

Changing Perspectives on Pediatric Human Papillomavirus (HPV) Vaccination among Dental Students and Residents Reveals Recent Increase in Vaccine Hesitancy

This study was a retrospective analysis of previously collected anonymous survey data regarding vaccine awareness, beliefs, and knowledge among dental (DMD) students and postgraduate (PG) residents. The protocol for this study was approved by the Institutional Review Board (IRB) as exempt. A total of 341 responses were collected from n = 293 DMD students and n = 48 PG residents. Although most respondents agreed that vaccines were necessary, safe, and effective, over the past 4 years (2017-2020) a growing percentage of respondents disagreed. In addition, although most respondents disagreed that there are too many required vaccines, vaccines can make you sick, or are dangerous, a growing percentage of respondents now agreed with these statements. Finally, although most respondents were aware of the HPV vaccine, recently a growing percentage of both students and residents reported they had insufficient information about this vaccine. These results provide novel insights into recent changes in attitudes and beliefs regarding vaccination among this population. Moreover, analysis of these shifts in attitudes and knowledge about HPV vaccination suggests that curricular integration of vaccine research and hesitancy may be needed to answer these questions in a supportive learning environment that fosters critical thinking and evidence-based practice and decision making.

Identifying the Utility of Dental Providers in Human Papillomavirus Prevention Efforts: Results From the National Health and Nutrition Examination Survey 2015-2018

PURPOSE

The aim of this study is to (1) examine the prevalence of human papillomavirus (HPV) vaccination in adolescents and young adults in the U.S., including those who had a dental visit in the last year but not a medical visit and (2) to determine an association between last visit to the dentist and HPV vaccination status.

METHODS

We conducted a cross-sectional study using data from the National Health and Nutrition Examination Survey from 2015 to 2018, including participants 9-26 years. Descriptive statistical analyses were conducted to characterize the study population and calculate the prevalence of HPV vaccination in adolescents and young adults, including those who had a dental visit in the last year but not a medical visit. Logistic regression analyses were performed to examine the association between last visit to the dentist and HPV vaccination status.

RESULTS

In total, 38.6% of participants were vaccinated for HPV, with higher prevalence of vaccination in those with the following characteristics: female, older age, higher income, higher education level, and having medical insurance. Participants who had a dental visit in the last year had an HPV vaccination rate of 40.8%. Of those who had a dental visit and were not vaccinated for HPV, 12.5% did not have a medical visit. Having a dental visit in the last year increased the odds of being vaccinated for HPV (odds ratio 1.69, confidence interval 1.26-2.28).

CONCLUSIONS

Dentists see a significant number of adolescents and young adults who are unvaccinated for HPV in a given year and could serve as an access point for HPV vaccine delivery in the future.
