Provider communication about HPV vaccination: A systematic review

A systematic review of practice-, provider-, and patient-level determinants impacting Asian-Americans' human papillomavirus vaccine intention and uptake

INTRODUCTION

Asian-Americans have been documented to have low human papillomavirus (HPV) vaccine initiation and completion. No research has attempted to examine underlying mechanisms of HPV vaccine uptake disparities among Asian-Americans. Using the P3 (practice, provider, and patient) model, this study aimed to identify practice-, provider-, and patient-level determinants of Asian-Americans' HPV vaccine intention and uptake.

METHODS

We conducted a systematic review of published literature regarding practice-, provider- and patient-level determinants of vaccine intention (e.g., intention, willingness, or acceptability) and uptake (e.g., initiation or completion). Eligible studies were those presenting empirical/original data, focusing on Asian populations in the U.S., including outcomes related to HPV vaccine intention and uptake, and analyzing data on factors associated with these outcomes separately for Asian groups.

RESULTS

Twenty-six studies (19 quantitative and 7 qualitative studies) were included in the review. Most commonly studied subgroups were Koreans (n = 9), Chinese (n = 6), and Cambodians (n = 5). Studies showed varied prevalence across subgroups (intention: 23.4%-72%; initiation: 14%-67%; completion: 9%-63%). Only 3 studies included measurements of practice-level determinants (language services, insurance policy). Twelve studies measured provider-level determinants (most commonly documented: HPV vaccine recommendation). All studies measured patient-level determinants (most commonly documented: HPV and HPV vaccine knowledge, perceived safety, perceived susceptibility, and perceived relationship between HPV vaccine and sexual activity).

CONCLUSIONS

Existing research on determinants of HPV vaccine intention and uptake among Asian-Americans currently lacks measurements of practice-level constructs and perspectives of clinic staff and providers, which are needed to guide system-level interventions and provider training. Data regarding patient-level determinants suggest that interventions for Asian-American populations can focus on providing educational information in culturally-appropriate manners, leveraging familial influences, and attending to access-related or cultural beliefs about HPV vaccine. Interventions should take into account varied vaccine intention and uptake prevalence in different Asian subgroups.

Social media engagement association with human papillomavirus and vaccine awareness and perceptions: Results from the 2017 US Health Information National Trends Survey

Due to social media's ability to publicize misinformation about vaccines, there is a need to study associations between social media engagement (SME) with human papillomavirus (HPV) and vaccine-related awareness and beliefs. Therefore, the study objectives were to (1) describe the SME of a nationally representative sample of US adults, and (2) determine the associations between SME and HPV-related awareness, HPV-related knowledge, HPV vaccine-related awareness, and perceived HPV vaccine efficacy. In 2019, we completed a secondary analysis of the 2017 Health Information National Trends Survey (Cycle 5.1). We created the SME index from 5 social media items. For each outcome variable, 3 models using binary and multinomial logistic regression were estimated. SME in the sample (n = 3171) was low (M = 0.9; range: 0-2). Respondents with higher SME had higher odds of HPV awareness (AOR = 1.56; 95% CI = 1.23, 1.99). Higher SME was associated with awareness of the HPV vaccine (AOR = 1.46; 95% CI = 1.16, 1.85). Respondents with higher SME had higher odds of perceiving HPV vaccine to be "not at all successful" (AOR = 2.22; 95% CI = 1.16, 4.24), "a little successful" (AOR = 1.99; 95% CI = 1.35, 2.94), "pretty successful" (AOR = 1.40; 95% CI = 1.04, 1.89), and "very successful" (AOR = 1.40; 95% CI = 1.02, 1.92) compared to those who selected "don't know" after adjusting for demographics and internet use. Our study highlights novel findings using a comprehensive SME index with a national sample providing insight to leverage existing consumer behaviors to better connect and disseminate accurate HPV information in a more strategic manner.

Parental intent to initiate and complete the human papillomavirus vaccine series in the USA: a nationwide, cross-sectional survey

BACKGROUND

Human papillomavirus (HPV) vaccine uptake among US adolescents is primarily dependent on the intent of their parents. To the best of our knowledge, an analysis quantifying parental intent to initiate and complete the HPV vaccine series in the USA at both the national and state level has not been done. We aim to estimate parental intent to initiate and complete the HPV vaccine series at the national-level and state-level and to identify reasons for lack of intent to initiate and complete the vaccine series.

METHODS

This cross-sectional study uses data from the adolescent component of the 2017-18 National Immunization Survey (NIS-Teen). Study participants were parents or caregivers of US adolescents aged 13-17 years, who were most knowledgeable about the immunisation status of the adolescents. The primary outcome was parental intent to vaccinate the adolescent in the next 12 months. The secondary outcomes were (1) the prevalence of reasons given for lack of intent to initiate and complete the HPV vaccine series, and (2) the relationship between receiving a recommendation from a health-care provider to vaccinate and intent to initiate the vaccination series. We computed national-level and state-level estimates for parental lack of intent to initiate and to complete the vaccine series; population-level estimates were derived using survey weights. A survey design-adjusted Wald F test was used for bivariate analysis. A multivariate logistic regression model was used to examine the association between health-care provider recommendation and parental intent to initiate the series. Analyses were stratified by history of health-care provider recommendation to initiate the HPV vaccine series.

FINDINGS

In 2017-18, the parent or caregiver of 82 297 US adolescents aged 13-17 years completed the NIS-Teen survey. 30 558 (37·1%) were unvaccinated and 9073 (10·8%) received only one HPV vaccine dose. Parents of 58·0% (17 171/29 086) of unvaccinated adolescents with data available on parental intent had no intention to initiate the HPV vaccine series. More than 65% of parents of unvaccinated adolescents in Idaho, Kansas, Michigan, Montana, Nebraska, North Dakota, Oklahoma, and Utah had no intention to initiate the HPV vaccine series. Parents of 23·5% (2166/9072) of initiators with data available on parental intent had no intention to complete the HPV vaccine series. More than 30% of parents in Arkansas, Florida, Georgia, Hawaii, Idaho, Utah, and West Virginia did not intend to complete the HPV vaccine series, whereas in the District of Columbia (11·2% [22/166]) and Rhode Island (20·4% [21/112]) parental lack of intent was relatively low (both regions have an HPV vaccine mandate). The most common reason for lack of intent among parents to initiate the vaccine for unvaccinated adolescents was safety concerns (22·8% [4182/16 455]); lack of a recommendation from a health-care provider (22·2% [440/1944]) was the most frequently cited reason for absence of intent to complete the series among parents of adolescents who received only one HPV vaccine dose. Receipt of a recommendation from a health-care provider was associated with greater odds of parental intent to initiate the HPV vaccine series (odds ratio 1·11, 95% CI 1·01-1·22). 45·5% (13 156/29 086) of parents of unvaccinated adolescents had reportedly received an HPV vaccine recommendation. Parents of 60·6% (7938/13 156) of unvaccinated adolescents with a recommendation from a health-care provider and data available on parental intent had no intention to initiate the series.

INTERPRETATION

Lack of parental intent to initiate and complete the HPV vaccine series for adolescents is a major public health concern in the USA. Combating vaccine safety concerns and strong recommendations from health-care providers could improve the currently suboptimal HPV vaccination coverage.

"There's Always Next Year": Primary Care Team and Parent Perspectives on the Human Papillomavirus Vaccine

Acceptance of the human papillomavirus (HPV) vaccination among parents and clinicians is high, but uptake remains low. Little is known about organizational and primary care team factors that influence the uptake of the HPV vaccine. Interviews with clinicians, clinic support staff, and parents of adolescent patients were conducted to better understand the interrelationships among the people and the organizational processes that influence HPV vaccine uptake at the point of care. Between July 2016 and February 2017, semi-structured interviews of 40 participants (18 clinicians, 12 clinic support staff, and 10 parents of adolescent patients) in a primary care network were conducted. Organizational structures and processes, such as electronic provider reminders, availability of "vaccination only" appointments, and knowledgeable primary care team members contributed to HPV vaccine uptake. Consistently high support of HPV vaccination was found among key informants; however, rather than refuse HPV vaccination, parents are opting to delay vaccination to a future visit. When parents express the desire to delay, clinicians and care team members described often recommending addressing HPV vaccination at a future visit, giving parents the impression that receiving the vaccine was not time-sensitive for their child. Discordance in HPV vaccination recommendations among providers and clinic support staff may contribute to delayed HPV vaccination. Strong, high-quality HPV vaccine recommendations are needed from all primary team members. Clinic interventions to accelerate HPV vaccine uptake may benefit from a team-based approach where every member of the primary care team is delivering the same consistent messaging about the importance of timely HPV vaccination.

Human papillomavirus vaccination 2020 guideline update: American Cancer Society guideline adaptation

The American Cancer Society (ACS) presents an adaptation of the current Advisory Committee on Immunization Practices recommendations for human papillomavirus (HPV) vaccination. The ACS recommends routine HPV vaccination between ages 9 and 12 years to achieve higher on-time vaccination rates, which will lead to increased numbers of cancers prevented. Health care providers are encouraged to start offering the HPV vaccine series at age 9 or 10 years. Catch-up HPV vaccination is recommended for all persons through age 26 years who are not adequately vaccinated. Providers should inform individuals aged 22 to 26 years who have not been previously vaccinated or who have not completed the series that vaccination at older ages is less effective in lowering cancer risk. Catch-up HPV vaccination is not recommended for adults aged older than 26 years. The ACS does not endorse the 2019 Advisory Committee on Immunization Practices recommendation for shared clinical decision making for some adults aged 27 through 45 years who are not adequately vaccinated because of the low effectiveness and low cancer prevention potential of vaccination in this age group, the burden of decision making on patients and clinicians, and the lack of sufficient guidance on the selection of individuals who might benefit.

Reasons for not receiving the HPV vaccine among eligible adults: Lack of knowledge and of provider recommendations contribute more than safety and insurance concerns

Background

The upward trends of vaccine exemptions in Texas are alarming. While HPV vaccine rates in this State are among the lowest nationwide, factors that contribute to the low HPV vaccination uptake among adults remain unknown. In this study, we examined the main reasons for not receiving HPV vaccination among age‐eligible adults.

Methods

The Texas health screening survey (2018), a multistage area probability design‐based survey of a representative sample of Texas residents, was used to identify 907 eligible adults (age ≥ 18 years) respondents, including 724 women aged ≤ 26 years in 2007 (≤38 years in 2018), and 183 men aged ≤ 21 years in 2011 (≤28 years in 2018). Participants who reported having never received an HPV shot, where asked the main reason for not receiving the vaccine.

Results

Overall, 58.5% (95%CI: 55.1‐62.0) of vaccine eligible adults reported having never received the HPV vaccine. The most commonly reported reasons for not receiving it were: did not know about the vaccine (18.5% (14.9‐22.1)), and provider did not recommend (14.1% (10.9‐17.4)). In contrast, commonly perceived reasons such as: safety concerns (7.2% (4.8‐9.5)), lack of insurance (3.4% (1.7‐5.1), and concerns about increasing sexual activity if vaccinated (0.2% (0.0‐0.5)), were less frequently reported.

Conclusion

Among vaccine‐eligible adults, safety and sexuality concerns do not appear to be the prime factors underlying low HPV vaccination rates. Rather than emphasizing them, educational interventions should aim at improving vaccine's knowledge, and enhancing provider recommendations on the necessity of HPV vaccination.

Intersectoral cooperation to increase HPV vaccine coverage: an innovative collaboration between Managed Care Organizations and state-level stakeholders

In order to reduce disparities in human papillomavirus (HPV) vaccine coverage, intersectoral approaches are needed to reach vulnerable populations, including Medicaid enrollees. This manuscript describes a collaboration between Medicaid Managed Care Organizations (MCOs), the American Cancer Society, and a state health department in a Midwestern state to address HPV vaccination. Qualitative interviews (n = 11) were conducted via telephone with key stakeholders from the three participating organizations using an interview guide designed to capture the process of developing the partnership and implementing the HPV-focused project. Interviews were transcribed and coded using thematic analysis. Interviewees described motivation to participate, including shared goals, and facilitators, like pooled resources. They cited barriers, such as time and legal challenges. Overall, interviewees reported that they believed this project is replicable. Conducting this project revealed the importance of shared vision, effective communication, and the complementary resources and experiences contributed by each organization. Valuable lessons were learned about reaching the Medicaid population and groundwork was laid for future efforts to serve vulnerable populations and reduce health disparities. This work has significant implications for other organizations seeking to partner with large nonprofits, state health departments, MCOs, or others, and the lessons learned from this project could be translated to other groups working to improve vaccination rates in their communities.

HPV: Injecting Truth into the Vaccine and Making Effective Recommendations

Human papillomavirus (HPV) immunization rates are significantly below the Healthy People 2020 target of 80% and lag behind other adolescent vaccines that are given at the same time. There is no top reason for parents' lack of HPV initiation, and many concerns could be addressed by talking to a health care provider. This article aims to equip clinicians with information regarding the impa-cts of HPV, address vaccine concerns, and guide clinicians with best practices regarding effective vaccine recommendations.[Pediatr Ann. 2020;49(6):e244-e247.].

Human Papillomavirus Vaccination Initiation and Completion among Youth Experiencing Homelessness in Seven U.S. Cities

Little is known about human papillomavirus (HPV) vaccination uptake among youth experiencing homelessness (YEH), who may be at higher risk for HPV than their housed counterparts. We examined the prevalence and associations of HPV vaccination initiation and completion among YEH. Guided by the Behavioral Model for Vulnerable Populations, we analyzed cross-sectional data collected from YEH (N = 1074; ages 18-26) in seven U.S. cities to assess HPV vaccination prevalence and to identify predisposing, enabling, and need factors associated with HPV vaccination status. Due to timing differences in the release of HPV vaccine recommendations, we conducted separate logistic regression analyses for men (n = 673) and women (n = 401). Approximately 19% of men and 37% of women had initiated and completed HPV vaccination. Several factors among men (i.e., older age, Latinx ethnicity, San Jose or St. Louis residence compared with New York City, never having had sex, and not previously being tested for STIs) and women (i.e., lower education level, San Jose or Houston residence compared with New York City, and never having had sex) were associated with lower odds of HPV vaccination initiation, completion, or both. Gay men had higher odds of initiating and completing the vaccination series than their heterosexual counterparts. Our findings reveal that HPV vaccination uptake is low among YEH and that there are vaccination disparities among subgroups of YEH. HPV vaccination strategies and resources that are easy-to-understand, facilitate point-of-care services, and address societal and system-level vaccination barriers encountered by YEH are needed.

An educational intervention to improve attitudes regarding HPV vaccination and comfort with counseling among US medical students

Many medical students are not comfortable recommending the human papillomavirus (HPV) vaccine because they do not feel prepared to discuss it with their patients. A prior study demonstrated that this is particularly a problem among unvaccinated students. Our purpose was to determine if medical student attitudes and comfort with counseling could be improved by attending a single lecture delivered by an expert on the topic. To assess the effects of the educational program, we conducted pre- and posttests on medical students before and after a single lecture on HPV vaccination. Changes in items related to attitude and comfort were examined. Student characteristics associated with changes in scores were also examined and compared. A total of 256 medical students participated in the pre- and posttests. Before the lecture, students demonstrated low knowledge of HPV vaccination and did not feel comfortable counseling parents of younger patients. However, students <30 years of age demonstrated significant improvements after the lecture in comfort. Asian and Hispanic students showed the greatest improvement in comfort with counseling, as did students who reported they had not received the HPV vaccine. Attending a single lecture given by an expert can improve medical students' attitudes and comfort with HPV vaccine counseling, especially if the students were not vaccinated themselves. This study suggests that including material on HPV vaccination in the standard medical student curriculum could help increase physician recommendation for the HPV vaccine.

Vaccine confidence: the keys to restoring trust

During the 20th century, the discovery of modern vaccines and ensuing mass vaccination dramatically decreased the incidence of many infectious diseases and in some cases eliminated them. Despite this, we are now witnessing a decrease in vaccine confidence that threatens to reverse the progress made. Considering the different extents of low vaccine confidence in different countries of the world, both developed and developing, we aim to contribute to the discussion of the reasons for this, and to propose some viable scientific solutions to build or help restore vaccine confidence worldwide.

Cognitive Bias in Clinicians' Communication about Human Papillomavirus Vaccination

National guidelines recommend human papillomavirus (HPV) vaccination for all 11-12-year-olds, but uptake among United States adolescents remains low. A major barrier to greater uptake is the lack of effective recommendations for HPV vaccine from clinicians. One potential influence on clinicians' recommendations for HPV vaccine that has been relatively unexplored is that of cognitive biases, or errors in judgement that result from 'mental shortcuts' used to make decisions under uncertainty. Therefore, we analyzed qualitative data from interviews with 32 pediatric clinicians using a framework of nine cognitive biases relevant to HPV vaccination: omission bias, ambiguity aversion, present bias, availability bias, optimism bias, naturalness bias, protected values, anchoring bias, and confirmation bias. We used a directed content analysis approach to iteratively code and analyze all transcripts in the dataset. We found evidence for several cognitive biases that were related to weaker recommendations for HPV vaccine. Commonly identified biases included anchoring bias (perception that vaccination unnecessary due to age/pubertal status); present bias (perception of burdens related to discussing vaccination), and optimism bias (belief that patient at low risk for HPV acquisition). We found less frequent evidence for ambiguity aversion (perception of missing information regarding vaccination) and omission bias (deferring vaccination). Other biases were identified infrequently or not at all. Our findings suggest that several cognitive biases may be an influence on clinicians' communication about HPV vaccine. Raising awareness of cognitive biases related to making HPV vaccine recommendations could help to strengthen the recommendations that clinicians provide.

Knowledge gaps and acquisition about HPV and its vaccine among Brazilian medical students

Objective

To analyze factors associated with knowledge gaps and acquisition about HPV and its vaccine among medical students.

Method

Cross-sectional and analytical study conducted at the University of São Paulo Medicine School, in 2016. A convenience sample of students completed a data collection instrument containing questions on knowledge about HPV and its vaccine, and vaccine acceptability. The level of knowledge and acceptability established as a "good level" was 80% of correct answers on the questionnaire. Internal validity was calculated with Cronbach's alpha value (α) = 0.74. Bivariate and multiple analyzes were performed using the Stata® program (Stata Corp, College Station, USA) 14.0.

Results

To evaluate the internal consistency of the instrument applied, the Cronbach's alpha equation was used, obtaining the alpha value (α) = 0.74 for this population. This value attests that the consistency of the answers obtained with this questionnaire is considered substantial and acceptable. Among the 518 medical students who completed the survey, the majority were men 312 (60.4%) with a mean age of 23 (± 2.8) years old; 199 (38.3%) of the students were in the final years of graduation (5th and 6th years). Students in the first, second and third year of study had a 51% higher risk of a knowledge gap when compared to students in the final years of graduation [PR 1.51 (1.3:1.8); p <0.001]. Men were at 22% higher risk of unsatisfactory knowledge than women are [PR 1.22 (1.07: 1.39). There was no knowledge acquisition during medical school in the following questions (p <0.05), indication of vaccine for individuals with HIV and contraindication in pregnant patients.

Conclusion

Male medical students, in the first year of medical school, and those who were not vaccinated had significant knowledge gaps about HPV. The novelty of the study includes the finding of non- acquisition of knowledge during the medical school graduation on safety and vaccination schedule and vaccine administration in specific populations.

Collaborating with Complementary and Alternative Medicine (CAM) Providers When Writing HPV Vaccine Review Articles

Novel strategies are needed to address vaccine hesitancy (VH), which correlates with complementary and alternative medicine (CAM). In Switzerland, CAM providers play important roles in vaccine counseling of vaccine hesitant (VH) parents, and traditional vaccination messaging tends to overlook CAM provider perspectives. In the setting of a Swiss national research program on VH, our key strategy has been to work together closely with CAM providers. To assess the feasibility of generating educational human papillomavirus (HPV) vaccine materials that would interest VH healthcare providers (HCPs), we invited four CAM providers to co-author two HPV vaccine review articles for general practitioners. We conducted thematic analysis of CAM provider comments to identify patterns that could complement and improve vaccination messaging from CAM perspectives. We identified several themes and generated an inventory of CAM provider messaging recommendations related to language use, presentation of background information, nuanced statements regarding HPV vaccine efficacy and safety, and communication tools that would be important to VH HCPs. Contrary to our initial expectations, and in an inclusive, respectful atmosphere of open dialogue, we were able to productively finalize our manuscripts. In the opinion of the CAM co-authors, the manuscripts effectively considered the communication needs and perspectives of VH HCPs. Engaging with CAM providers appears to be a feasible and innovative avenue for providing vaccine information and designing communication tools aimed at VH healthcare providers.

Factors associated with adolescent HPV vaccination in the U.S.: A systematic review of reviews and multilevel framework to inform intervention development

Multilevel factors impact HPV vaccine series initiation and completion among adolescents in the U.S. Synthesis of these factors is needed to inform intervention development and to direct future research. Current frameworks synthesizing factors focus on females only and do not include both series initiation and completion outcomes. We conducted a systematic review of reviews to identify modifiable individual-, provider-, and clinic-level factors associated with HPV vaccination outcomes among U.S. adolescents and developed a multilevel framework illustrating relations between factors to inform intervention development. We searched Medline, PsychInfo, Pubmed, CINAHL, and ERIC databases and included reviews published 2006 to July 2, 2018 describing individual-, provider-, or clinic-level factors quantitatively associated with HPV vaccination among U.S. adolescents. Two coders independently screened reviews, extracted data, and determined quality ratings. Sixteen reviews containing 481 unique primary studies met criteria. Factors synthesized into the multilevel framework included parent psychosocial factors (knowledge, beliefs, outcome expectations, intentions) and behaviors, provider recommendation, and patient-targeted and provider-targeted clinic systems. The scope of our framework and review advances research in two key ways. First, the framework illustrates salient modifiable factors at multiple levels on which to intervene to increase HPV vaccination. Second, the review identified critical gaps in the literature at each level. Future research should link the body of literature on parental intentions to vaccination outcomes, identify provider psychosocial factors associated with recommendation behaviors and subsequent vaccine uptake in their patient population, and understand clinic factors associated with successful implementation of patient- and provider-targeted system-level interventions.

Factors influencing rates of human papillomavirus vaccination

Purpose

Failure modes and effects analysis (FMEA) was used to identify ways in which community clinic practices related to suboptimal human papillomavirus (HPV) vaccination rates could be improved.

Method

FMEA is a standardized safety method that helps determine where processes fail, the impact of failures, and needed process changes. In a quality improvement initiative conducted at an academic health center–based community clinic, a multidisciplinary team used FMEA to map HPV vaccination processes and identify areas for improvement of vaccination practices. Risk priority numbers (RPNs) were assigned to identified failure modes based on likelihood of occurrence, likelihood of detection, and ability to correct locally. Failure modes with the highest RPNs were targeted for process improvements.

Results

High RPN failure modes were related to clinic processes for follow-up, immunization status checks during well-child visits, and vaccination discussions during sick-child visits. New procedures included scheduling follow-up vaccinations and reminders during the initial vaccination appointment. HPV immunization rates improved following implementation of these procedures, indicating that clinic processes focused on patient follow-up can impact vaccination series completion.

Conclusion

FMEA processes can help health systems identify workflow barriers and locally relevant opportunities for improvement. Team-based approaches to care process improvements can also benefit from standardized problem identification and solving.

The effects of message framing and healthcare provider recommendation on adult hepatitis B vaccination: A randomized controlled trial

Many adults in the U.S. do not receive recommended vaccines, and the research literature remains inconclusive on the best communication strategies for increasing this behavior. This study examined the association of message framing (gained-framed vs. loss-framed vs. control), and healthcare provider (HCP) recommendation (offered vs. recommended) on uptake of adult hepatitis B virus (HBV) vaccination in a high risk population using a 3 × 2 block design randomized controlled trial. Fear of shots, fear of vaccines, and perceived message framing were examined in secondary analyses. Of the 1747 participants, 47.7% (n = 833) received 0 doses of HBV vaccine, 27.8% (n = 485) received 1 dose, 10.4% received 2 doses, and 14.1% received all 3 recommended doses. There was not a significant interaction between message framing and HCP recommendation (p = .59). Mean number of doses received by the gain-framed group (m = 0.96) was not significantly different from the loss-framed group (m = 0.97, RR = 0.99, 95% CI = 0.88-1.12). However, those receiving any framing message received significantly more doses (m = 0.96) than those in the control condition (m = 0.81, RR = 1.17, 95%CI = 1.06-1.31). Participants who received a HCP recommendation received significantly more vaccine doses (m = 0.95) than those in the vaccine-offered condition (mean = 0.82, RR = 1.16, 95%CI = 1.05-1.28). These results suggest there is no difference in vaccine uptake between gain-frame and loss-frame messages, but both are better than a control message. These results also support advising HCP to provide a strong recommendation for vaccinations beyond merely offering it to patients. This study has implications for vaccine uptake beyond HBV, and can inform future research on effective vaccine communication research. Clinicaltrials.gov Identifier: NCT00739752. Registration date: August 20, 2008.

Online media scans: Applying systematic review techniques to assess statewide human papillomavirus vaccination activities

Background. Although the human papillomavirus (HPV) vaccine has been approved for use in adolescents in the US for over a decade, vaccination uptake remains low. Of concern, HPV vaccine coverage is below the national average in Minnesota, USA. To understand the reach of current HPV programming and research, we use an online media scan; this method may be applied to other jurisdictions to gain insight about various public health issues. Design and Methods. This online media scan describes the nature and scope of ongoing activities to increase HPV vaccination in Minnesota. The media scan included: a) structured internet searches of HPV vaccine health education/promotion activities ongoing in Minnesota since 2013, and b) searches in research databases of the published literature on HPV vaccination in Minnesota from 2013 to 2018. Results. Searches resulted in 880 online and 142 research article matches, with 40 and 36 meeting selection criteria. Results were categorized by activities focusing on race/ethnicity, sex, health providers, parents, lesbian, gay, bisexual, transgender and queer or questioning (LGBTQ) populations, geographic location, catchup vaccination, and insurance status. Most activities were statewide (52% health education/promotion and 35% research), followed by activities located in entirely urban areas (15% health education/promotion and 41% research) with only 6% of health education/promotion activities and 2% of research activities carried out in entirely rural areas. Conclusions. A range of local and statewide HPV vaccine health education/promotion and research activities were identified in Minnesota. Several efforts partnered with American Indian and Somali/Somali-American communities, but fewer activities focused on HPV vaccination among LGBTQ youth and HPV vaccination in rural areas.

Human papillomavirus vaccination among diverse college students in the state of Georgia: who receives recommendation, who initiates and what are the reasons?

Young adulthood is a critical time for catch-up HPV vaccination. We assessed predictors of vaccine recommendation and initiation among college students. We analysed cross-sectional surveys from 2397 students using multivariable logistic regressions. Guided by the Socio-ecological and Health Belief Models, measures included socio-demographic characteristics, intrapersonal measures (e.g. vaccine beliefs), interpersonal measures (e.g. doctor's recommendation) and institutional-level measures (e.g. college settings). The sample included students from private, public, technical and historically black colleges/universities. Of the sample, 64.5% were White; additionally, 48.3% of women (n = 750/1552) and 18.8% of men (n = 159/845) received a doctor's recommendation. Among women, predictors included older age, US-born, higher parental education and attending private schools. Among men, predictors included younger age, being homosexual and attending private schools. HPV vaccine series initiation was low-43.3% of women (n = 672) and 16.7% of men (n = 141). Doctor's recommendation predicted initiation for both sexes. Younger women, women attending technical colleges and men of 'multiple/other' race had lower odds of initiation. Common initiation barriers for both sexes included a lack of doctor recommendation and sexual inactivity. These barriers and the associations between nativity, race and socio-economic status with vaccine recommendation and initiation should be further investigated. Interventions should improve patient-provider communication around HPV vaccine.

HPV Vaccine recommendations: does a health care provider's gender and ethnicity matter to Unvaccinated Latina college women?

Objectives: There are disparities in the uptake of HPV vaccine among racial/ethnic minority women. The strongest predictor of HPV vaccine uptake among adult women is health care provider (HCP) recommendation; however, it is unclear how issues relating to race/ethnicity may mitigate these recommendations. Research shows that racial/ethnic and gender concordance between a patient and HCP can improve patient satisfaction, access and quality of care. If concordance contributes to improved patient-provider interactions, then it may be a factor in patient decisions regarding HPV vaccination. The objectives of this study were to (1) explore gender and ethnicity HCP preference regarding HPV vaccination among unvaccinated; and (2) understand factors associated with those preferences. Design: Unvaccinated Latina college students (n = 187) completed a survey that assessed HCP preferences, medical mistrust, cultural assimilation and HPV vaccine recommendation. Logistic regression models evaluated associations between above variables with HPV knowledge and preference for a female and/or Latina HCP. Results: Most respondents had health insurance (71%), a regular HCP (64%), were US-born (67%), with foreign-born parents (74%). Thirty-four percent and 18% agreed that they would be more likely to get the HPV vaccine if the recommending HCP was female and Latino, respectively. Latina women reporting higher medical mistrust preferred a HPV vaccine recommendation from a Latino/a provider. Conclusions: Latinas' preferences regarding gender and ethnicity of their HCPs may affect patient-provider interactions. Increasing diversity and cultural awareness among HCPs, and providing linguistically and culturally-appropriate information may decrease patient-provider mistrust, increase uptake of the HPV vaccine, and decrease persistent cervical cancer disparities.

Communication around HPV vaccination for adolescents in low- and middle-income countries: a systematic scoping overview of systematic reviews

BACKGROUND

Human papillomavirus (HPV) infection causes cervical cancer. More than 80% of those diagnosed with cervical cancer live in low- and middle-income countries (LMICs). The World Health Organization recommends vaccination as a public health measure against cervical cancer. Communication interventions are able to change how people think about vaccination and are thus instrumental in addressing vaccine hesitancy. Our aim was to provide a broad scoping overview of the available evidence on communication with adolescents, parents, and other stakeholders around HPV vaccination for adolescents, with a specific focus on LMICs.

METHODS

We conducted a systematic scoping overview of systematic reviews addressing a range of questions regarding communication around HPV vaccination. We considered reviews published between 2007 and 2018 focusing on communication around HPV vaccination and that searched for qualitative or quantitative studies for inclusion. We searched the Epistemonikos database which includes reviews from multiple electronic databases. Two overview authors screened titles and abstracts and examined potentially eligible reviews in full text. Data extraction was performed by one overview author and verified by a second. We assessed the reliability of the included reviews using an adapted version of AMSTAR 2.

RESULTS

We included twelve reviews in our overview. Four reviews assessed the effectiveness of communication interventions. These interventions intended to inform or educate about HPV and HPV vaccination, such as videos and fact sheets, or to remind or recall, such as text message reminders. Eight reviews assessed factors associated with HPV vaccination uptake, including communication-related factors such as whether the vaccine was recommended by a physician and people's knowledge regarding the vaccine. Nine reviews searched for studies from LMICs, but most found only a small number of studies from these countries.

CONCLUSIONS

The small number of studies identified from LMICs is of concern as these countries face the largest burden of disease related to HPV. This scoping overview also found and excluded a number of reviews because of important methodological limitations, highlighting the need for future reviews to use appropriate methods. The overview indicates areas in which further primary studies are needed on HPV vaccination communication in LMICs.

Associations between HPV vaccination among women and their 11-14-year-old children

The human papillomavirus (HPV) vaccine has been available in the United States for over a decade. We sought to examine the associations between self-reported receipt of HPV vaccination among women and their 11-14-year-old children in 27 low-coverage states. Among the 3,261 mothers we surveyed, 18% reported receiving ≥1 dose of HPV vaccine. A significantly higher proportion of vaccinated women reported vaccination of their children compared to unvaccinated women (83% vs. 56%, p < .001). In multivariable logistic regression, vaccinated women (vs. unvaccinated) had 3.58 (95% CI: 2.81-4.56) times the adjusted-odds of vaccinating their children (≥1 dose HPV vaccine). Among unvaccinated children, vaccinated mothers (vs. unvaccinated) had 3.32 (95% CI: 2.09-5.26) times the adjusted odds of high intention to vaccinate their children in the next 12 months. We did not observe associations between mothers' vaccination confidence and their vaccination status. We conclude that mothers who received ≥1 dose of HPV vaccine may be more likely to initiate or highly intend to initiate the HPV vaccine series for their children. This may have important implications for meeting population goals for HPV vaccination coverage as an increasing proportion of mothers are likely to be vaccinated over time.

A "Sense"-ational HPV Vaccination Quality Improvement Project in a Family Medicine Residency Practice

BACKGROUND

Human papillomavirus (HPV) vaccination uptake for adolescents and young adults in the United States remains far from national goals. Using a multi-component intervention aligned with community-wide efforts, we implemented a quality improvement project to increase HPV vaccinations among 9-26 year-old male and female patients in an urban, low income, minority population family medicine residency practice.

METHODS

The pre-intervention year was November 2, 2014 to October 31, 2015 and the intervention year was November 1, 2015 to October 31, 2016. Based on community input and published literature, the interventions were creative, practice-specific provider-, patient-, and system-level strategies. To compare pre- and post-intervention vaccinations, HPV vaccination data were extracted from an electronic medical record request for age-eligible patients seen in the practice during the intervention year. Chi-square, McNemar's and 2-tailed, 2-sample Z tests were used to test differences in vaccination initiation (≥1 dose) and completion (3 doses) across groups and over time.

RESULTS

Despite high pre-intervention rates (58% and 75%), HPV vaccine initiation significantly increased 12.8 percentage points (PP) for males and 10.6 PP for females from pre- to post-intervention (P < 0.001). HPV vaccine completion also significantly increased 16 PP for males and 10.9 PP for females (P < 0.001). Young adult patients (18-26 years-old) had significant increases in completion rates (9.9 PP; P < 0.001), not observed among adolescents (20 PP; ns).

CONCLUSIONS

Consistent and abundant positive HPV vaccination messaging, low-cost sensory rewards, process change, and community, clinician, and nonclinical staff engagement were associated with higher HPV vaccine initiation and completion, especially among young adults.

Facilitators and Barriers to the Implementation of the HPV VACs (Vaccinate Adolescents Against Cancers) Program: A Consolidated Framework for Implementation Research Analysis

PURPOSE AND OBJECTIVES

The human papillomavirus (HPV) vaccine is an effective but underused method for preventing multiple cancers, particularly cervical cancer. Although interventions have successfully targeted barriers to HPV vaccine uptake in various clinical settings, few studies have explored their implementation. Our study examines the delivery of the HPV VACs (Vaccinate Adolescents Against Cancer) Program and elicits information on barriers and facilitators to implementation.

INTERVENTION APPROACH

The VACs Program pilot was a multilevel, evidence-based intervention conducted by the American Cancer Society in 30 federally qualified health centers (FQHCs) in the United States.

EVALUATION METHODS

We conducted in-depth interviews (N = 32) by telephone with representatives of 9 FQHC partners. We structured the interview guides on Consolidated Framework for Implementation Research (CFIR) domains. We asked about project start-up activities, implementation strategy selection, policy- and practice-level changes, staffing structure, challenges, and key factors leading to project success. At least 2 researchers coded each interview transcript verbatim.

RESULTS

Participants most frequently identified the electronic health record system, training and education, concrete tools and resources, and provider champions as facilitators to implementing HPV VACs. Limited staff resources, challenges of electronic health records, issues with state immunization registries, patient misinformation about vaccines and vaccine stigma, cultural/language barriers, competing priorities, levels of funding, staff buy-in, training needs, and low health literacy were identified as barriers.

IMPLICATIONS FOR PUBLIC HEALTH

Providing appropriate training for FQHC staff members and providers along with technical assistance and facilitation tools were critical for increasing provider confidence in recommending HPV vaccine. Addressing capacity-building and implementation barriers in FQHCs can increase effective implementation of evidence-based interventions to increase HPV vaccination uptake and reduce the burden of future cancers.

Factors Associated with School Nurses' and Personnel's Professional Practice to Encourage Parents to Vaccinate Against Human Papillomavirus

BACKGROUND

School nurses and personnel play a vital role in promoting the human papillomavirus (HPV) vaccine. The purpose of this study was to identify factors associated with school nurses' and personnel's professional practice to provide parents with HPV vaccine information and to encourage parents to vaccinate their child against HPV.

METHODS

School nurses and personnel from Ohio and Missouri completed a survey to assess their professional practice in providing HPV vaccine information and encouraging parents to vaccinate their child against HPV. Independent variables included demographics, HPV knowledge/attitudes, perceptions of their as an opinion leader for the HPV vaccine, self-efficacy to provide vaccine education, and perception of school district support.

RESULTS

Providing parents with HPV vaccine information was predicted by age, role within the school, grade-serving, knowledge, perceptions, self-efficacy, and district support; accounting for 38% of the variance (p < .000, R²  = .38). Encouraging parents to vaccinate their child against HPV was predicted by perception, self-efficacy, and grade-serving; accounting for 39% of the variance (p < .000, R²  = .39).

CONCLUSIONS

To enhance school nurses' and personnel's professional practice, interventions should focus on nurses' and personnel's perception of their role as opinion leaders and self-efficacy to provide HPV education and vaccine recommendation.

HPV vaccination has not increased sexual activity or accelerated sexual debut in a college-aged cohort of men and women

Background

The human papillomavirus (HPV) is the most common sexually transmitted infection and is linked to several types of cancer. HPV vaccination uptake in the U.S. is relatively low, despite the vaccine’s high efficacy. Some parents of adolescents have concerns that vaccination will encourage sexual behavior and therefore choose not to vaccinate. Previous studies investigating vaccination and sexual behavior have included only young women and girls.

Methods

The objective of this study is to assess associations between HPV-vaccination and sexual behavior in a college-age cohort of both men and women. We analyzed questionnaire data collected from the Michigan HPV and Oropharyngeal Cancer Study, a cohort study designed to investigate HPV infection and its association with sexual behavior (data collected 2015–17, Ann Arbor, MI). Here, we consider vaccination status, sexual behavior, and substance use among 241 college-aged men and women. Logistic, Poisson, and Cox regression were used to determine the relationship between probability of sexual debut, number of sexual partners, and HPV vaccination status at baseline as well as between age at sexual debut and vaccination status at debut.

Results

HPV vaccination status was not significantly associated with an increased likelihood of sexual debut (odds ratio: 0.80 (95% CI: 0.41–1.58), decreased age of sexual debut (hazard ratio: 0.81 (95% CI: 0.65–1.00), nor an increased number of sexual partners (per year sexually active; incidence rate ratio: 1.27 (95% CI: 0.86–1.87)) in this cohort, after controlling for age, race, sex, and substance use. Instead, race or alcohol use were independent predictors of sexual behavior.

Conclusions

Concerns about the influence of the HPV vaccine on sexual behavior are likely unfounded for both men and women. These results can aid in increasing vaccine acceptability, inform and strengthen physician recommendations, and ultimately reduce the burden of HPV and HPV-related cancers in the U.S.

Abandoning Medical Authority: When Medical Professionals Confront Stigmatized Adolescent Sex and the Human Papillomavirus (HPV) Vaccine

Despite authority's centrality to the medical profession, providers routinely forgo their medical authority during clinical encounters. Research focuses on patients challenging medical authority but indicates these confrontations are uncommon and providers seldom relinquish their authority in response. Using rare data of 75 audio recordings of adolescent vaccine discussions during clinical encounters and interviews with and observations of medical staff, I examine how staff leverage or abandon their medical authority to convince parents to vaccinate. I find medical professionals use less authority when at risk of stigmatizing patients: Medical professionals are less authoritative when recommending human papillomavirus (HPV) vaccination versus other adolescent vaccines, particularly when addressing the need to vaccinate before sexual onset due to concerns of labeling the child as sexually active. Medical staff defer to parents in ways that potentially discourage HPV vaccine uptake: They encourage HPV vaccination less than other vaccines and infrequently challenge parents' sex-related reasons for vaccine refusal.

Use of community forums to increase knowledge of HPV and cervical cancer in African American communities

Cervical cancer adversely impacts African American communities. While disparities in incidence remain unclear, communities continue to use forums to increase cervical cancer education. The purpose of this paper is to examine the efficacy of using community forums to increase human papillomavirus vaccine (HPVV) and cervical cancer knowledge in African American communities. This study is a one-group pretest-posttest study design using a 17-item questionnaire to collect data from 412 participants in diverse communities. Our analyses revealed perceived knowledge increased significantly after the forums for African American participants. For African Americans, perceived knowledge prior to the forums was explained by gender, access to care, and trust in clinical trials. After the forum, perceived knowledge was associated with access to care and trust in vaccines. Participants who had health insurance reported higher perceived HPV and cervical cancer knowledge and greater trust in vaccines. This study found community forums that address the cultural and historical context of research mistreatment related to HPVV development and include diverse racial/ethnic representation of stakeholders may be a useful strategy to increase HPVV, and cervical cancer knowledge in African American communities.

Cervical Cancer Patients' Willingness and Ability to Serve as Health Care Educators to Advocate for Human Papillomavirus Vaccine Uptake

Human papillomavirus (HPV) causes nearly all cervical cancer. Only half of females and less than half of males receive the recommended HPV vaccine dose. This study explores whether cervical cancer patients may serve as health advocates to adolescents and their parents in encouraging the uptake of the HPV vaccine. The study targeted an opportunity sample of women seen in the gynecology oncology clinic with a diagnosis of cervical cancer. During interviews, patients were asked about the following: provider conversations regarding cervical cancer, knowledge of HPV and the vaccine, discussions with family or friends about the causes or prevention of cervical cancer, and whether they would be willing to talk with others about the HPV vaccine. Twenty-three interviews were conducted in 2016-2017. Patients ranged from 28 to 61 years of age. Four team members developed a coding list, then used these themes to code the interviews. Six themes resulted from the analysis of the transcripts: (1) Expressions of fears, questioning effectiveness of vaccine; (2) Low level of health literacy; (3) Acquiring health information from television, internet; (4) Provider conversations (with patients regarding HPV and the vaccine); (5) Patient stigma surrounding cervical cancer; (6) Patients' willingness to serve as a health care educator. While cervical cancer patients overall expressed a willingness to serve as health care educators, barriers remain. Low health literacy and a lack of understanding of the causes of cervical cancer persist. These issues will need to be addressed in order for cervical cancer patients to be effective advocates.

Young Deaf Adults' Knowledge of Human Papillomavirus and Human Papillomavirus Vaccine's Effectiveness in Preventing Cervical, Anal, Penile, and Oral Cancer

STUDY OBJECTIVE

To describe knowledge and risk perception of human papillomavirus (HPV) among deaf adults who use American sign language (ASL) comparison with hearing adults in the United States.

DESIGN

Secondary HPV knowledge data for the deaf subset sample were drawn from the Health Information National Trends survey in ASL that was administered between 2015 and 2018. HPV knowledge data for the hearing subset sample were drawn from cycle 5 of the Health Information National Trends survey in English that was administered in 2017.

SETTING

Surveys are a nationally based survey of deaf ASL users in the United States and a nationally based survey of hearing non-ASL users in the United States.

PARTICIPANTS

The age of the deaf and hearing subset samples was determined on the basis of catchup vaccine eligibility criteria as outlined by the Centers for Disease Control and Prevention that recommends catchup vaccination in women, men who have sex with men, immunocompromised individuals, and those who identify as transgender.

INTERVENTIONS AND MAIN OUTCOME MEASURES

We examined HPV, HPV vaccine, and HPV-related cancer knowledge in deaf and hearing subsets.

RESULTS

Our sample consisted of 235 deaf and 115 hearing adults aged 18-26 years. Of the deaf participants 58% (136/235) reported knowledge of HPV compared with 84% (97/115) of hearing participants (P < .001). Hearing participants showed higher accuracy in risk perception of HPV relation to cervical cancer compared with deaf participants (P < .001). Hearing participants were more likely to have heard of the HPV vaccine as well as believe it is successful in preventing cervical cancer compared with deaf participants (P < .001).

CONCLUSION

Deaf ASL users are less likely to have knowledge of HPV, virus-related cancer risk, and preventative vaccination compared with hearing peers.

Social Determinants of Human Papillomavirus Vaccine Uptake: An Assessment of Publicly Available Data

OBJECTIVES

Despite cancer prevention benefits associated with the human papillomavirus (HPV) vaccine, uptake in the United States is relatively low among males and females. Our objective was to use the Healthy People 2020 social determinants of health framework to determine the availability and characteristics of data on economic, educational, social, health care, and community factors affecting HPV vaccine uptake in the United States.

METHODS

We included the most recent data sets from 6 publicly available, US-based, federally funded surveys that contained at least 1 measure of HPV vaccination among adolescents and young adults. We searched each data set for any social determinants of health measures within the 5 domains of the framework: economic stability, education, social and community context, health and health care, and neighborhood and built environment.

RESULTS

The social determinants of health domains of education, economic stability, and health and health care appeared in all data sets. The domains of social and community context and neighborhood and built environment appeared in only 3 data sets. Even when domains were represented, we discovered gaps in the data sets, in which only limited measures of the social determinants were available.

CONCLUSION

The addition of questions about the social determinants of health to the surveys that generate these data sets, particularly in the domains of social and community context and neighborhood and built environment, would strengthen the ability of public health researchers, policy makers, and professionals to identify associations between the social determinants of health and HPV vaccine uptake.

Characterizing Trends in Human Papillomavirus Vaccine Discourse on Reddit (2007-2015): An Observational Study

Background

Despite the introduction of the human papillomavirus (HPV) vaccination as a preventive measure in 2006 for cervical and other cancers, uptake rates remain suboptimal, resulting in preventable cancer mortality. Social media, widely used for information seeking, can influence users’ knowledge and attitudes regarding HPV vaccination. Little is known regarding attitudes related to HPV vaccination on Reddit (a popular news aggregation site and online community), particularly related to cancer risk and sexual activity. Examining HPV vaccine–related messages on Reddit may provide insight into how HPV discussions are characterized on forums online and influence decision making related to vaccination.

Objective

We observed how the HPV vaccine is characterized on Reddit over time and by user gender. Specifically, this study aimed to determine (1) if Reddit messages are more related to cancer risks or sexual behavior and (2) what other HPV vaccine–related discussion topics appear on Reddit.

Methods

We gathered all public Reddit comments from January 2007 to September 2015. We manually annotated 400 messages to generate keywords and identify salient themes. We then measured the similarity between each comment and lists of keywords associated with sexual behavior and cancer risk using Latent Semantic Analysis (LSA). Next, we used Latent Dirichlet Allocation (LDA) to characterize remaining topics within the Reddit data.

Results

We analyzed 22,729 messages containing the strings hpv or human papillomavirus and vaccin. LSA findings show that HPV vaccine discussions are significantly more related to cancer compared with sexual behavior from 2008 to 2015 (P<.001). We did not find a significant difference between genders in discussions of cancer and sexual activity (P>.05). LDA analyses demonstrated that although topics related to cancer risk and sexual activity were both frequently discussed (16.1% and 14.5% of word tokens, respectively), the majority of online discussions featured other topics. The most frequently discussed topic was politics associated with the vaccine (17.2%). Other topics included HPV disease and/or immunity (13.5%), the HPV vaccine schedule (11.5%), HPV vaccine side effects (9.7%), hyperlinks to outside sources (9.1%), and the risks and benefit of HPV vaccination (8.5%).

Conclusions

Reddit discourse on HPV vaccine encompasses a broad range of topics among men and women, with HPV political debates and cancer risk making up the plurality of the discussion. Our findings demonstrated that women and men both discussed HPV, highlighting that Reddit users do not perceive HPV as an issue that only pertains to women. Given the increasing use of social media as a source of health information, these results can inform the development of targeted online health communication strategies to promote HPV vaccination to young adult users of Reddit. Analyzing online discussions on Reddit can inform health communication efforts by identifying relevant, important HPV-related topics among online communities.

The Role of Dental Providers in Preventing HPV-Related Diseases: A Systems Perspective

Successfully educating dental providers and patients about the link between human papillomavirus (HPV) and oropharyngeal cancer requires coordinated efforts to increase HPV-related prevention practices. The aim of this study was to identify, using a systems perspective, the multi-level determinants related to how dental providers can promote HPV prevention in dental practices. Data for this qualitative study were collected in 2015-16 from focus groups with dentists (four focus groups, n=33), focus groups with dental hygienists (four focus groups, n=48), and in-depth interviews with dental opinion leaders (n=13). Results were triangulated and mapped along micro, meso, and macro system levels. At the micro level, participants identified patient characteristics and low self-efficacy as influential determinants when discussing HPV prevention. At the meso level, relationships among dentists, dental hygienists, and the physical practice environment were factors affecting dental providers' HPV prevention efforts. At the macro level, professional organizations impacted how dental providers interacted with their patients on this topic. These results suggest that improving HPV prevention among dental providers requires a multi-level approach that considers the distinctive context of dental settings, dental training, and perceptions of professional roles. The findings suggested that the macro- and meso-level determinants may be challenging to modify due to the distinctive culture and practice models of dentistry. Nevertheless, the association between HPV and oral cancer requires an expansion of prevention strategies used in dental practices. Improving dental providers' self-efficacy to communicate HPV prevention through continuing education and integration of skill-guided training in dental and dental hygiene curricula could facilitate this process.

Dental opinion leaders' perspectives on barriers and facilitators to HPV-related prevention

Evidence suggests a causal connection between the Human Papillomavirus (HPV) and oropharyngeal cancers. HPV-related oropharyngeal cancers are increasing and are the most common HPV-associated cancer. Previous research suggests that dental professionals recognize a role in the prevention of HPV and oropharyngeal cancers. As an initial step to investigating effective mechanisms of incorporating HPV prevention into dental practices, including the HPV vaccine, this qualitative study explored dental opinion leaders' perspectives on barriers and facilitators to HPV-related prevention in the dental profession. Dental opinion leaders were identified through: (1) national professional organizations and advocacy groups, (2) by indication of an expert panel, and (3) focus groups conducted with oral health providers. Thirteen participants representing 11 organizations were interviewed via telephone. Interview recordings were transcribed verbatim and thematically coded using a priori and emergent codes. Opinion leaders described multi-level factors influencing dental providers' HPV-related prevention practice behaviors. Barriers included HPV as a sensitive topic and the need for HPV-related education and skills. Facilitators included perceptions of HPV prevention as part of the dental providers' role and the potential development of passive educational methods to provide HPV-related information to patients. Opinion leaders reported dental providers have a role in the prevention of HPV and oropharyngeal cancer; yet, to fully incorporate this topic into their practice, dental providers need further education and skill-based training. Opinion leaders have significant role in shaping this topic as a priority and identifying potential interventions to assist dental providers' HPV-related prevention. Future research should maximize the role of opinion leaders as key change agents.

Knowledge, attitudes and factors associated with acceptability of human papillomavirus vaccination among undergraduate medical, dental and nursing students in South India

Purpose: To evaluate knowledge, attitudes and factors associated with acceptability of human papillomavirus (HPV) vaccine among undergraduate medical, dental, and nursing students in South India. Methods: Using a post-test study design, a convenience sample of 988 students (age 18-26 years) were surveyed. The primary outcome was vaccine acceptability (likely to intend to receive the vaccine). Bivariate analysis using Chi-Square test of independence and multivariate binary logistic regression analysis was used to examine factors associated with vaccine acceptability. Results: Out of 988 students surveyed, majority had heard about cervical cancer (95%), HPV (89.3) or genital warts(77.5). Only 59.7% had heard of HPV vaccine prior to the survey; 65.2% intended to receive the vaccine and 68.3% were willing to recommend the vaccine to others. Participants aged <22 years were less likely to accept the vaccine (OR:0.85, CI:0.76-0.96) compared with participants aged older than 22 years. Medical students (OR:1.12, CI:1.03-1.23), students who reported alcohol use (OR:1.15, CI:1.03-1.29) and those with moderate knowledge scores were more likely to intend to receive the vaccine (OR:1.14, CI:1.04-1.24), compared to others. On multivariate analysis, only course (OR 1.366, CI 1.016-1.835) and attitude score (OR 4.17; CI 2.12-8.2) were statistically associated with intention to receive the HPV vaccine. Conclusion: Two-thirds of students intended to receive the HPV vaccine. Although the overall awareness of the HPV-related disease and prevention is good, considerable knowledge gaps exists in many areas suggesting that that more education about HPV disease and benefits of vaccination should be included in the undergraduate medical school curriculum.

Persuasive messaging for human papillomavirus vaccination by adolescent providers in a five-country multi-site study

OBJECTIVE

Strong persuasive messaging by providers is a key predictor for patient acceptance of prophylactic human papillomavirus vaccination. We aimed to determine optimal messaging to promote human papillomavirus adolescent vaccination across different geographical sites.

METHODS

Adolescent providers (n = 151) from Argentina, Malaysia, South Africa, South Korea, and Spain were surveyed on messages, family decision makers, and sources of communication to best motivate parents to vaccinate their adolescent daughters overall, and against human papillomavirus. Multivariate logistic regression assessed the likelihood of recommending messages specifically targeted at cervical cancer with providers' characteristics: gender, medical specialization, and previous administration of human papillomavirus vaccination.

RESULTS

Mothers were considered the most important human papillomavirus vaccination decision makers for their daughters (range 93%-100%). Television was cited as the best source of information on human papillomavirus vaccination in surveyed countries (range 56.5%-87.1%), except Spain where one-on-one discussions were most common (73.3%). Prevention messages were considered the most likely to motivate parents to vaccinate their daughters overall, and against human papillomavirus, in all five countries (range 30.8%-55.9%). Optimal messages emphasized cervical cancer prevention, and included strong provider recommendation to vaccinate, vaccine safety and efficacy, timely vaccination, and national policy for human papillomavirus vaccination. Pediatricians and obstetricians/gynecologists were more likely to cite that the best prevention messages should focus on cervical cancer (OR: 4.2, 95% CI: 1.17 to 15.02 vs other medical specialists).

CONCLUSIONS

Provider communication messages that would motivate parents to vaccinate against human papillomavirus were based on strong recommendation emphasizing prevention of cervical cancer. To frame convincing messages to increase vaccination uptake, adolescent providers should receive updated training on human papillomavirus and associated cancers, while clearly addressing human papillomavirus vaccination safety and efficacy.

HPV vaccine recommendation profiles among a national network of pediatric practitioners: understanding contributors to parental vaccine hesitancy and acceptance

Background: Practitioner communication is one of the most important influences and predictors of HPV vaccination uptake. The objective of this study was to conduct a latent class analysis characterizing pediatric practitioner HPV recommendation patterns. Methods: Pediatric practitioners of the American Academy of Pediatrics' (AAP) Pediatric Research in Office Settings (PROS) national network completed an online survey where they were presented with 5 hypothetical vignettes of well child visits and responded to questions. Questions asked about their use of communication strategies, assessments about the adolescent patient becoming sexually active in the next 2 years for decision-making about HPV vaccine recommendation, and peer norms. Latent class analysis characterized practitioner subgroups based on their response patterns to 10 survey questions. Multinomial logistic regression examined practitioner characteristics associated with each profile. Results: Among 470 respondents, we identified three distinct practitioner HPV vaccine recommendation profiles: (1) Engagers (52%) followed national age-based guidelines, strongly recommended HPV vaccination, and perceived peers as strongly recommending; (2) Protocol Followers (20%) also strongly recommended HPV vaccination, but were less likely to engage families in a discussion about benefits; and (3) Ambivalent HPV Vaccine Recommenders (28%) delayed or did not recommend HPV vaccination and were more likely to use judgment about whether adolescents will become sexually active in the next two years. Practicing in a suburban setting was associated with twice the odds of being an Ambivalent Recommender relative to being an Engager (OR = 2.2; 95% CI:1.1-4.1). Conclusions: Findings underscore the importance of continued efforts to bolster practitioner adoption of evidence-based approaches to HPV vaccine recommendation especially among Ambivalent Recommenders.

Importance of a team approach to recommending the human papillomavirus vaccination

BACKGROUND AND PURPOSE

Few studies have examined human papillomavirus (HPV) vaccine communication in the context of the health care team.

METHODS

In 2016, the investigators conducted a national, online survey of U.S. parents who reported having discussed HPV vaccination with their adolescent's health care team. Multivariable logistic regression assessed associations between HPV vaccine initiation (≥1 dose) and having: 1) discussed HPV vaccination with multiple team members and 2) received congruent recommendations about HPV vaccination.

CONCLUSIONS

Of the 795 parents in the sample, about half (52%) reported discussing HPV vaccination with multiple team members, including nurse practitioners, nurses, and physicians. Most reported receiving congruent recommendations for (76%) or against (12%) HPV vaccination; few (12%) received mixed recommendations. Parents who discussed HPV vaccination with multiple team members had greater odds of series initiation (odds ratio [OR] = 2.34, 95% CI: 1.61-3.40), whereas those who received mixed versus congruent recommendations for HPV vaccination had lower odds of vaccination (OR = 0.56, 95% CI: 0.33-0.95).

IMPLICATIONS FOR PRACTICE

Findings suggest that a coordinated team approach to recommendations may encourage HPV vaccination. Nurse practitioners are well positioned to facilitate coordination efforts within their clinical practices.

Effective HPV Vaccination Strategies: What Does the Evidence Say? An Integrated Literature Review

PROBLEM

The updated Advisory Committee on Immunization Practices (ACIP) 2016 guidelines recommends vaccination for the human papillomavirus (HPV) for all adolescents starting at ages 11-12 years. The United States continues to fall short of the benchmarks set by Healthy People 2020. The national vaccination rates hover at 49.5%, creating much room for improvement in health care systems. The purpose of this literature review was to identify evidence-based interventions to implement for improved outcomes.

ELIGIBILITY CRITERIA

An integrative literature review was conducted using the CINAHL, EBSCO, Academic Search Complete, ProQuest and Medline databases. The search was limited to studies published in peer reviewed journals in the last 10 years.

SAMPLE

Of the available studies, 201 met inclusion criteria with 46 studies meriting further review.

RESULTS

Barriers to vaccination included missed opportunities due to lack of provider recommendation and awareness of current guidelines, and parental vaccination hesitancy. Effective strategies included reminder systems and strong provider recommendations.

CONCLUSIONS

No one method has been effective in maintaining increases in vaccination rates. Multi-method strategies demonstrate the highest rates of maintaining increases in HPV vaccination. Strong provider recommendations are a cornerstone to any multi-method intervention.

IMPLICATIONS

Providers and nurses need to shift conversations to strong recommendations for the HPV vaccination and include additional reminder systems, including protocols to meet Healthy People 2020 goals for HPV vaccination.

Implementation of Strategies to Improve Human Papillomavirus Vaccine Coverage: A Provider Survey

INTRODUCTION

Human papillomavirus (HPV) vaccine coverage in the U.S. is persistently suboptimal, despite research describing barriers to vaccination and strategies to increase vaccination coverage. The objective was to assess providers' approach to the HPV vaccine and their implementation of strategies to increase HPV vaccination coverage. The hypothesis was that adoption of improvement measures to address underuse of the HPV vaccine has not occurred.

METHODS

Community pediatric providers from two Midwestern practice-based research networks completed self-administered electronic surveys. Data were collected over 6 months in 2015 and organized and analyzed in 2016.

RESULTS

There were 100 providers that participated. Despite agreement with national recommendations, some providers delayed their recommendation until the adolescent was older and many reported missed vaccination opportunities. Many providers experienced parental concerns including safety of the HPV vaccine, belief their child was not at risk of HPV infection, and their child's resistance to receiving multiple shots. Providers identified the following as barriers to adherence to Advisory Committee on Immunization Practices guidelines: bad publicity of the HPV vaccine, information about the HPV vaccine on the web, and a lack of a follow-up system for those who delayed HPV vaccine initiation. Approximately half of the participants had implemented strategies to address these barriers beyond offering immunization-only appointments.

CONCLUSIONS

Participants were aware of barriers to HPV vaccine use, but many had not adopted a systematic approach to increase vaccine coverage. A better understanding of the challenges facing providers to adopting improvement measures and a strategy to address barriers to implementation are needed to improve HPV coverage.

Parental awareness of Meningococcal B vaccines and willingness to vaccinate their teens

Background:

In the US, Meningococcal B (MenB) vaccines were first licensed in 2014. In 2015, the Advisory Committee on Immunization Practices recommended that parents of teens talk to their provider about receiving MenB vaccine, rather than issuing a routine recommendation. We assessed parental awareness of MenB vaccines and willingness to vaccinate their teens with MenB vaccines compared to MenACWY vaccines, which have been routinely recommended for many years.

Methods:

We surveyed parents of teens attending high school in 2017–18 during the Minnesota State Fair. Parents reported via iPad their knowledge of and concern about meningococcal disease and their awareness of and willingness to vaccinate with MenB and MenACWY vaccines. We assessed the relationship between meningococcal disease knowledge and concern, MenB and MenACWY vaccine awareness, and willingness to vaccinate with MenB and MenACWY using adjusted logistic regression.

Results:

Among 445 parents, the majority had not heard of the newly introduced MenB vaccines Bexsero^® (80.0%; 95% CI: 76.0–83.6) or Trumenba^® (82.0%; 95% CI: 78.1–85.5) or the MenACWY vaccines Menactra^® or Menveo^® (68.8%; 95% CI: 64.2–73.0). The majority were at least somewhat willing to vaccinate their teen with MenB vaccine (89.6%; 95% CI: 86.5, 92.3) and MenACWY vaccine (91.2%; 95% CI: 88.2, 93.7). Awareness of MenB vaccines (OR: 3.8; 95% CI: 1.2–12.2) and concern about meningococcal disease (OR: 3.1; 95% CI: 1.5–6.3) were significantly associated with willingness to vaccinate with MenB vaccine.

Conclusions:

Awareness of MenB vaccine is lacking among parents of teens but is an important predictor of willingness to vaccinate with the newly licensed MenB vaccines.

Decline in HPV-vaccination uptake in Denmark - the association between HPV-related media coverage and HPV-vaccination

BACKGROUND

In 2014, Denmark experienced a rapid decline in vaccination uptake for the human papillomavirus (HPV) vaccine after a successful introduction of the vaccine in 2009. Before the decline, the uptake of the first HPV vaccine was around 90% for girls born in the period 1998 to 2000, while it dropped to 54% for girls born in 2003. The decline followed negative public attention from 2013 coinciding with increasing suspected adverse-event reporting to the Danish Medicines Agency. The aim of this study is to describe the HPV-vaccination uptake, to quantify relevant HPV-related media coverage, and analyse the relation between media coverage and HPV-vaccination acceptance in Denmark in year 2009-2016.

METHODS

Three types of data were used for the analysis: Immunisation data from 243,415 girls, media coverage (8524 news items) and Google search activity. We used changes in the correlation between media coverage and vaccination uptake to identify a changing point in their relationship. The relationship before and after the changing point was analysed determined on the interactions between vaccination uptake, media and search activity, with search activity as a proxy for public attention.

RESULTS

We identified July 2013 as a changing point in the relationship between media coverage and vaccination uptake. We found no significant relationship between media coverage and vaccination uptake in the first part of the time series (June 2009 to June 2013), whereas from July 2013 and onwards there was a negative Pearson's correlation of - 0.52. The changing point coincides with both an increase in Google searches for "HPV side effects" and media coverage with negative content.

CONCLUSIONS

Following a successful launch of the HPV-vaccination programme, concerns about vaccine safety shifted the public opinion and the coverage by the media. The noticeable shift in correlation between vaccination uptake and media coverage before and after July 2013 could indicate that increased media coverage influenced the decline in vaccination uptake. Media monitoring may represent an important tool in future monitoring and assessment of confidence in vaccination programmes.

Reasons for Lack of HPV Vaccine Initiation in NIS-Teen Over Time: Shifting the Focus From Gender and Sexuality to Necessity and Safety

PURPOSE

To describe changes in parents' reasons for lack of HPV vaccine initiation in American male and female adolescents from 2010 to 2016.

METHODS

Log binomial regression was used to examine prevalence and trends across time in reasons parents do not intend to vaccinate from the National Immunization Survey - Teen (NIS-Teen).

RESULTS

In females, safety concerns were the most common reasons in 2010 (23%) and 2016 (22%). Lack of necessity (21% vs. 20%), knowledge (14% vs. 13%), and recommendation (9% vs. 10.0%) remained stable, whereas child's lack of sexual activity decreased from 19% to 10% (p<.01). For males, lack of necessity (24% vs. 22%), recommendation (22% vs. 17%), and knowledge (16% vs. 14%), and child's lack of sexual activity (16% vs. 9%) and gender (13% vs. 2%) decreased from 2010 to 2016 (p<.05). Safety concerns increased (5% vs. 14%) (p<.01).

CONCLUSIONS

Vaccine messages should reflect current trends and focus on persistent concerns about knowledge, safety, and necessity, rather than sexuality and gender.

Outreach and Reminders to Improve Human Papillomavirus Vaccination in an Integrated Primary Care System

This study evaluated the impact of health system-based outreach and reminders on human papillomavirus (HPV) vaccine series initiation and completion. Parents of 10 to 12 year olds (n = 1805) were randomized to receive either (1) an outreach letter and brochure recommending HPV vaccination followed by automated HPV vaccine reminders or (2) usual care. We interviewed a subset of 50 parents to assess program acceptability. Outcomes were HPV vaccine initiation during the study period and on-time series completion. Rates of HPV vaccine initiation during the study period (July 2015 to August 2016) were similar between the intervention and control groups, but initiation within 120 days of randomization was higher in the intervention group (23.6% and 18.8%, P = .04) as was completion during the study period (10.3% vs 6.8%, P = .04). Reminders for doses 2 and 3 did not affect completion. The program was acceptable to parents. This study provides evidence that health system-based outreach and reminders can improve HPV vaccination.

What is the most useful tool in HPV vaccine promotion? Results from an experimental study

Introduction: Human papillomavirus infection (HPV) affects 70-80% of female population throughout the lifetime, exposing them to the risk of developing genital warts and cervical cancer. Despite these correlated risks and the demonstrated efficacy of the vaccine, coverage rates for two-three doses are around 70% in Italy and 67% in Piemonte (below the expected 95%). Aim of the study is to investigate whether this situation is due to a lack of information and awareness among young adults. Results: Students showed increased knowledge after the intervention and more than 90% found the 3 informative materials as sources of useful information. After the intervention students would strongly recommend HPV vaccination (OR = 3.45; p < 0.001). Discussion: Higher rates of correct answers after the distribution of informative material underline the importance of knowledge delivery. Differences among the kind of material were reported; it appears that a combination of leaflet's positive features, such as clarity and intelligibility, and article's completeness of information represents the best solution to reach communication goals in vaccination campaigns targeted on educated populations. Methods: Researchers conducted an experimental study on a large population of undergraduate students from University of Turin. Participants' knowledge about HPV was assessed with questionnaires before and after the examination of 3 different kinds of informative material (journal article describing HPV infection, gynecologist video-interview and institutional leaflet about HPV prevention) on HPV and vaccine. Differences among groups were explored by using univariate tests, differences in pre- post- knowledge were assessed with McNemar tests. Relevant associations were searched with logistic regression models.

National Trends in Parental Human Papillomavirus Vaccination Intentions and Reasons for Hesitancy, 2010-2015

Background

Human papillomavirus (HPV) vaccination uptake remains lower than other recommended adolescent vaccines in the United States. Parental attitudes are important predictors of vaccine uptake, yet little is known about how they have changed over time.

Methods

Participants included US residents aged 13-17 years with documented vaccination status who had received <3 doses of HPV vaccine whose parents responded to the National Immunization Survey-Teen, 2010-2015.

Results

Of the 76971 participants, 63.0% were male, 58.8% were non-Hispanic white, and 14.4 years was the median age. The percentage of unvaccinated teens decreased from 2010 to 2015, yet, annually, parents of unvaccinated teens of both sexes most often reported that they were "not likely at all" to vaccinate their teen. The percentage decreased significantly from 41.5% to 31.2% (P < .001) for parents of unvaccinated females from 2010 to 2015 but did not change among parents of males from 2012 to 2015. Conversely, parents of undervaccinated teens of both sexes reported higher and increasing vaccination intent over time. In 2015, nearly one-third of parents of unvaccinated teens reported that the vaccine was "not needed/necessary." Concerns about vaccine safety and side effects declined among parents of unvaccinated females but increased among parents of males (7.3% to 14.8%; P < .001).

Conclusions

Although parental vaccination intent and knowledge improved over time, intent remains low and many parents still have significant concerns about HPV vaccination, even after series initiation. Multiple strategies are needed to improve series initiation and completion in the United States.

A retrospective and prospective look at strategies to increase adolescent HPV vaccine uptake in the United States

The HPV vaccine debuted more than ten years ago in the United States and many strategies have been evaluated to increase HPV vaccination rates, which include not only improving current vaccination behaviors but also sustaining these behaviors. Researchers and practitioners from a variety of backgrounds have engaged in this work, which has included efforts directed at public health and government policies, health education and health promotion programs, and clinical and patient-provider approaches, as well as work aimed to respond to and combat anti-HPV vaccination movements in society. Using a previously developed conceptual model to organize and summarize each of these areas, this paper also highlights the need for future HPV vaccine promotion work to adopt a multi-level and, when possible, integrated approach in order to maximize impact on vaccination rates.

Parents' Views on the Best and Worst Reasons for Guideline-Consistent HPV Vaccination

Background: Human papillomavirus (HPV) vaccination could prevent most HPV-associated cancers, but few U.S. adolescents are vaccinated according to guidelines. To inform efforts to counsel parents more effectively, we sought to quantify their views on the best and worst reasons for guideline-consistent HPV vaccination. We hypothesized that parents' views would differ according to their vaccination confidence.Methods: We developed a best-worst scaling experiment to evaluate 11 reasons healthcare providers commonly give for HPV vaccination. The instrument was administered in 2016 via a national online survey to 1,177 parents of adolescents. Parents completed 11 choice tasks of 5 reasons each, indicating the best and worst reason in each task. We used conditional logistic regression to rank reasons for the sample overall and by vaccination confidence (low/high).Results: Parents viewed cancer prevention as the best reason for HPV vaccination (P < 0.001). Other commonly endorsed reasons were preventing a common infection, having lasting benefits, or being a safe vaccine (all P < 0.001). Reasons viewed as worst were: It is a scientific breakthrough; I got it for my own child; and your child is due (all P < 0.001). Stratified analyses indicated small differences in how often parents with low versus high vaccination confidence endorsed messages (P < 0.001), but the two groups ranked reasons similarly overall.Conclusions: Parents prioritized cancer prevention as the best reason for guideline-consistent HPV vaccination. Several other common reasons, including having vaccinated one's own child, may warrant additional testing.Impact: Providers should emphasize cancer prevention when discussing HPV vaccination, as recommended by the Centers for Disease Control and Prevention, the President's Cancer Panel, and others.

Implementing a Multipartner HPV Vaccination Assessment and Feedback Intervention in an Integrated Health System

CONTEXT

Human papillomavirus (HPV) vaccine initiation rates are persistently lower than rates for other adolescent-recommended vaccines. Assessment and feedback interventions are a recommended strategy for improving vaccination rates.

OBJECTIVE

To provide a guide for implementing a multipartner intervention to increase HPV vaccine initiation rates.

SETTING

Nine primary care facilities within the Kaiser Permanente Northwest (KPNW) health care system.

INTERVENTION

In 2015-2016, we implemented a system-wide assessment and feedback intervention to promote HPV vaccination. In partnership with the Centers for Disease Control and Prevention, the Oregon Immunization Program, and KPNW's leadership, we developed an education session combining information on HPV infection, parental communication strategies, and facility-specific coverage data.

RESULTS

Twelve months postintervention, HPV dose 1 vaccination coverage increased from 71% to 72% among females and from 65% to 68% among males.

CONCLUSIONS

A collaborative approach was critical to engaging leadership and enlisting support from providers and to developing appropriate materials for clinical audiences. Information provided here can be used as a guide for conducting assessment and feedback interventions focused on HPV vaccination initiation.
