A Mixed-Methods Examination of Factors Related to HPV Vaccination Promotion in Private Dental Settings, Iowa, 2019

Identifying System-Level Strategies to Engage in HPV Prevention Across Oral Health and Primary Care Settings

INTRODUCTION

HPV vaccination prevents most HPV-related cancers, yet uptake remains low. HPV is linked to an estimated 70% of oropharyngeal cancers (OPCs) in the US and outnumber cases of HPV-related cervical cancers. Not all OPCs can be detected through routine screening, making HPV vaccination a more effective primary prevention strategy. However, bridging primary and oral healthcare faces challenges due to a lack of referral networks between practices. The purpose of this study is to identify key infrastructure elements and policies, as well as HPV prevention strategies, among an academic practice network of dental clinics and partnering community health clinics in a southeastern state.

METHODS

Researchers held interviews with directors and focus groups with staff at six dental clinics and eight associated community clinics in a southeastern state. Interviews and focus groups at dental and community clinics were analyzed by two study team members using thematic analysis with Nvivo software.

RESULTS

A total of 90 participants participated in all focus groups and interviews (N = 14 interviews, 10 focus groups (5-13 participants per focus group). Most participants identified as white (58.9%) and female (70%), with an average age of 38.5 years. Researchers identified nine key study themes: three specific to the dental clinics' HPV conversations with patients, two related to community clinics' vaccine provision, and four involving the relationship between the dental and co-located community clinics. Dental clinic staff do not currently discuss HPV with patients. They are open to discussing HPV with patients but anticipate barriers that require preparation to overcome them. Community clinics have demonstrated previous success with HPV vaccination, but patients over the age of 18 face financial barriers to vaccination. Community clinics and dental clinics report that they do not currently have existing referral networks but are open to a referral system between practices if infrastructure is put into place to support it.

CONCLUSIONS

Our findings indicate that there is interest in, and potential for, increased discussion of HPV with dental patients and collaboration between dental and community clinics for HPV vaccination referral. The results of this investigation can be used to develop intervention strategies to increase HPV vaccination through referrals between dental clinics and nearby community clinics. Ultimately, this work can reduce health inequities in HPV-related cancers, serve as a model for US dental practices, and possibly influence public health policy.

Assessing a Continuing Education Course for Dental Hygienists to Improve HPV and HPV Vaccine Knowledge and Self-efficacy

Human papillomavirus is the most common sexually transmitted infection and causes anogenital and oropharyngeal cancers. Although HPV-related cancers can be prevented through vaccination, HPV vaccination rates are low compared to other vaccines. One of the strongest indicators for vaccination is provider recommendation, and dental health providers are well positioned to promote HPV vaccination among their patients. The purpose of this study was to determine if a continuing education (CE) course could improve dental hygienists' HPV-related knowledge and self-efficacy related to HPV vaccination recommendations. Data were collected from a sample of participants (n = 202) at a large dental hygiene conference in the southern US. A pre- and post-tests were administered with the CE course and differences in HPV vaccine knowledge and self-efficacy in counseling, recommending, and referring for the HPV vaccine were analyzed using SAS. HPV vaccine knowledge overall significantly increased post-CE (p < .001) and improvement was seen among several specific knowledge areas. However, knowledge regarding the common sites of HPV-related oral and oropharyngeal cancers remained moderate (82% correct) even after the CE intervention. There was no significant change from pre-test to post-test in participants' self-efficacy related to counseling patients about the HPV vaccine, recommending the HPV vaccine to patients, or referring patients for the vaccine. This study demonstrates that continuing education can improve dental hygienists' HPV-related knowledge. Since dental providers may play an important role in HPV-related cancer prevention, future work should develop continuing education tools that can motivate changes in self-efficacy and ultimately improve practice behaviors.

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.

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.

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.
