Completeness of Human Papilloma Virus Vaccination: A Systematic Review

An Integrative Review of the Influence on Human Papillomavirus Vaccination Adherence among Adolescents

To enhance the vaccination rate of adolescents against HPV, understanding their current vaccination intentions and identifying the factors that influence their decision to vaccinate are imperative. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) was used to search for relative literature. Five electronic databases (CINAHL, PubMed, Web of science, Research Information Sharing Service (RISS) and Korea Citation Index (KCI)) were searched from 2007 to 2022, and 19 studies were selected for final review. The Mixed Methods Assessment Tool (MMAT) was used as a critical appraisal tool to evaluate the quality for various types of research designs. This integrative review revealed three themes, including facilitators (personal characteristics and environmental factors), barriers (lack of awareness and knowledge about HPV, concerns about side effects, and the burden of costs), and ways to increase vaccination uptake (knowledge promotion and HPV vaccines coverage by public insurance). To encourage HPV vaccine uptake, it is essential to enhance public knowledge, create compelling advertisements, and ensure that the vaccines are covered by public insurance. Moreover, providing educational programs that emphasize the effectiveness and significance of HPV vaccines to adults who can influence the vaccination decisions of adolescents is vital.

Communication strategies to improve human papillomavirus (HPV) immunisation uptake among adolescents in sub-Saharan Africa: a systematic review and meta-analysis

OBJECTIVES

Developing countries face the greatest cervical cancer disease burden and mortality with suboptimal immunisation uptake. This review explores the communication strategies adopted, successes, challenges and lessons learnt in sub-Saharan countries to enhance human papillomavirus (HPV) immunisation.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

PubMed, Hinari, Cochrane Library, Trip database, CINAHL, Web of Science, Scopus and seven grey resources were searched through May 2022.

ELIGIBILITY CRITERIA

We included observational studies addressing communication strategies for HPV immunisation uptake.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers used standardised methods to search, screen and code included studies. Data extraction and assessment of risk of bias were done in duplicate to enhance validity of the results. Meta-analysis was conducted using the random-effects model. Findings were summarised and synthesised qualitatively.

RESULTS

Communication intervention to facilitate decision-making achieved uptake rate of 100% (95% CI 0.99% to 1.00%), followed by intervention to enable communication, which achieved 92% (95% CI 0.92% to 0.92%). Communication intervention to inform and educate achieved 90% (95% CI 0.90% to 0.90%).Targeting both healthcare workers and community leaders with the communication intervention achieved 95% (95% CI 0.91% to 0.98%), while teachers and school boards achieved 92% (95% CI 0.84% to 1.01%). Targeting policymakers achieved 86% (95% CI 0.78% to 0.93%).Based on the method of communication intervention delivery, use of training achieved an uptake rate of 85% (95% CI 0.84% to 0.87%); similarly, drama and dance achieved 85% (95% CI 0.84% to 0.86%). However, use of information, education and communication materials achieved 82% (95% CI 0.78% to 0.87%).

CONCLUSION

HPV vaccine communication is critical in ensuring that the community understands the importance of vaccination. The most effective communication strategies included those which educate the population about the HPV vaccine, facilitate decision-making on vaccine uptake and community ownership of the vaccination process immunisation.

Human papillomavirus dose reminder preferences among parents from a diverse clinical sample: a qualitative study

Reminders are an important method for encouraging patients to return for follow-up visits, such as for successive doses of the human papillomavirus (HPV) vaccine. However, patients may have preferences for different types of reminders. This study examined which reminder methods parents of pediatric patients found most useful and their thoughts on how the reminders helped them to complete their children’s HPV vaccine series. This qualitative study was conducted on a purposively sampled group of parents who participated in a multi-level intervention intended to improve uptake and completion of the HPV vaccine series. Parents who agreed to participate were interviewed by phone using semi-structured interviews about their satisfaction with different program components, including reminders they received. Interviews were conducted between May 26, 2016 and October 18, 2017. Thematic analyses of data were conducted using NVivo software. Among 269 program participants invited to participate in the interviews, 157 agreed (58.4%) and 89 were successfully interviewed (33.1%). Participants thought that reminders were effective at helping them return for follow-up visits to ensure their children received all recommended HPV vaccine doses. Although most parents preferred texts, many also favored other reminder methods by themselves or in combination with texts. Parents suggested that the reminders indicate the purpose of the appointment and for which child. Reminders are an important part of a multi-component intervention that aims to increase completion of the HPV vaccine series. Program enrollees prefer different types of reminders, so offering several options may improve returns for follow-up doses.

Maximizing Participant Engagement, Participation, and Retention in Cohort Studies Using Digital Methods: Rapid Review to Inform the Next Generation of Very Large Birth Cohorts

BACKGROUND

Many current research needs can only be addressed using very large cohorts. In such studies, traditional one-on-one phone, face-to-face, or paper-based engagement may not be feasible. The only realistic mechanism for maintaining engagement and participation at this scale is via digital methods. Given the substantial investment being made into very large birth cohort studies, evidence for optimal methods of participant engagement, participation, and retention over sustained periods without in-person contact from researchers is paramount.

OBJECTIVE

This study aims to provide an overview of systematic reviews and meta-analyses evaluating alternative strategies for maximizing participant engagement and retention rates in large-scale studies using digital methods.

METHODS

We used a rapid review method by searching PubMed and Ovid MEDLINE databases from January 2012 to December 2019. Studies evaluating at least 1 e-engagement, participation, or retention strategy were eligible. Articles were screened for relevance based on preset inclusion and exclusion criteria. The methodological quality of the included reviews was assessed using the AMSTAR-2 (Assessing the Methodological Quality of Systematic Reviews 2) measurement tool, and a narrative synthesis of the data was conducted.

RESULTS

The literature search yielded 19 eligible reviews. Overall, 63% (n=12) of these reviews reported on the effectiveness of e-engagement or participation promotion strategies. These evaluations were generally not conducted within very large observational digital cohorts. Most of the contributing reviews included multipurpose cohort studies (with both observational and interventional elements) conducted in clinical and research settings. Email or SMS text message reminders, SMS text messages or voice notifications, and incentives were the most commonly used design features to engage and retain participants. For parental outcomes, engagement-facilitation interventions influenced uptake and behavior change, including video feedback, goal setting, and intensive human facilitation and support. Participant-stated preferences for content included new knowledge, reminders, solutions, and suggestions about health issues presented in a clear, short, and personalized way. Perinatal and postpartum women valued self-monitoring and personalized feedback. Digital reminders and multiple SMS text messages were specific strategies that were found to increase adherence to medication and clinic attendance, respectively.

CONCLUSIONS

This review adds to the growing literature evaluating methods to optimize engagement and participation that may apply to large-scale studies using digital methods; it is promising that most e-engagement and participation promotion strategies appear to be effective. However, these reviews canvassed relatively few strategies, suggesting that few alternative strategies have been experimentally evaluated. The reviews also revealed a dearth of experimental evidence generated within very large observational digital cohort studies, which may reflect the small number of such studies worldwide. Thus, very large studies may need to proactively build in experimental opportunities to test engagement and retention approaches to enhance the success of their own and other large digital contact studies.

Internal and External Validity of Social Media and Mobile Technology-Driven HPV Vaccination Interventions: Systematic Review Using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) Framework

Social media human papillomavirus (HPV) vaccination interventions show promise for increasing HPV vaccination rates. An important consideration for the implementation of effective interventions into real-world practice is the translation potential, or external validity, of the intervention. To this end, we conducted a systematic literature review to describe the current body of evidence regarding the external validity of social media HPV vaccination-related interventions. Constructs related to external validity were based on the reach, effectiveness, adoption, implementation, maintenance (RE-AIM) framework. Seventeen articles published between 2006 and 2020 met the inclusion criteria. Three researchers independently coded each article using a validated RE-AIM framework. Discrepant codes were discussed with a fourth reviewer to gain consensus. Of these 17 studies, 3 were pilot efficacy studies, 10 were randomized controlled trials (RCTs) to evaluate effectiveness, 1 was a population-based study, and 3 did not explicitly state which type of study was conducted. Reflecting this distribution of study types, across all studies the mean level of reporting RE-AIM dimensions varied with reach recording 90.8%, effectiveness (72.1%), adoption (40.3%), implementation (45.6%), and maintenance (26.5%). This review suggests that while the current HPV vaccination social media-driven interventions provide sufficient information on internal validity (reach and effectiveness), few have aimed to gather data on external validity needed to translate the interventions into real world implementation. Our data suggest that implementation research is needed to move HPV vaccination-related interventions into practice. Included in this review are recommendations for enhancing the design and reporting of these HPV vaccination social media-related interventions.

Use of patient navigators to increase HPV vaccination rates in a pediatric clinical population

A patient navigator (PN) program was implemented in pediatric clinics to increase uptake of the human papillomavirus (HPV) vaccine. The purpose of this study is to examine the impact of this program. All visits between April 1, 2013 and December 31, 2017 for 9-17 year old patients at 3 program and 5 non-program clinics were examined using electronic medical records. These dates included patient visits before and after program initiation (February 1, 2015). Visits including 1 dose of the HPV vaccine were assessed as a proportion of total visits for each month. Multivariable binary logistic regression was used to examine the odds of HPV vaccination across time, between program and non-program clinics, and age group. A total of 128,051 visits by 21,395 patients were examined. HPV vaccines were administered during 12,742 visits (10.0%). Odds of HPV vaccination during visits by 13-17 year olds was greater than during visits by 9-12 year olds in the pre-intervention period (odds ratio [OR]: 1.12, 95% confidence interval [CI]: 1.04-1.19). However, this association changed during the intervention period, with odds of HPV vaccination among visits by 13-17 year olds lower compared to visits by 9-12 year olds (OR: 0.78, 95% CI: 0.75-0.82). The odds of HPV vaccination were elevated among 9-12 year olds in program clinics as compared to 2014, the year before the program was implemented. Having on-site PNs can increase the frequency of HPV vaccination in pediatric clinics, particularly among patients 9-12 years of age.

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.

Caregiver acceptance of a patient navigation program to increase human papillomavirus vaccination in pediatric clinics: a qualitative program evaluation

Objective: The purpose of this evaluation was to examine the acceptability of a multi-component patient navigator (PN) intervention program designed to decrease barriers to human papillomavirus (HPV) vaccination among caregivers of adolescents. We sought to understand the most important components of the program from the caregivers' perspective and to evaluate remaining barriers to vaccination. Method: Caregivers of children 9-17 years old (N = 102) participated in qualitative semi-structured interviews with questions informed by the Theory of Planned Behavior. These interviews assessed experiences with a PN program which offered HPV vaccination, scheduling, and reminders in pediatric clinics. We included randomly selected 46 program participant transcripts and 11 decliner transcripts. A thematic approach was used to analyze transcripts for themes related to acceptability of HPV vaccination, important program components, and any problems encountered. Results: Major themes included: reasons for making HPV vaccination decision, helpful program components and suggestions for improvement, and remaining barriers to vaccination. Those who declined vaccination stated that their child was too young or not ready to think about sex, or they did not have enough information to make a decision. However, they felt that PNs were respectful of their decision. Program participants felt that vaccination was an important way to prevent cancer. Program participants had often not been aware of the vaccine and felt that having it explained was very helpful. Conclusion: This program evaluation found that caregivers of pediatric patients, even those who declined the HPV vaccine, appreciated the program and felt it provided important information about the vaccine.
