Completion of the Human Papillomavirus Vaccination Series Among Adolescent Users and Nonusers of School-Based Health Centers.

ABSTRACT: OBJECTIVES:Uptake and completion of the human papillomavirus (HPV) vaccine series among adolescents are suboptimal in the United States. We examined immunization registry data to determine completion of the 3-dose HPV vaccine series among adolescents in Seattle, Washington, born during 1995-2000 who received ?1 dose of HPV vaccine. METHODS:Immunization data included the administrating facility, which identified adolescents who used school-based health centers (SBHCs) for any HPV vaccine dose. We calculated completion of the 3-dose series at any time and on time by the 13th birthday. We stratified analyses by sex and assessed differences in on-time and any-time completion between users and nonusers of SBHCs. RESULTS:Overall, 67.9% (8612 of 12?676) of females and 41.8% (3560 of 8521) of males with ?1 dose of HPV vaccine completed the 3-dose series. Compared with female SBHC nonusers, female SBHC users had 37% higher odds of completing the series at any time (adjusted odds ratio [aOR] = 1.37; 95% CI, 1.19-1.58) and 33% higher odds of completing the series on time (aOR = 1.33; 95% CI, 1.08-1.64). Compared with male SBHC nonusers, male SBHC users had 45% higher odds of completing the series at any time (aOR = 1.45; 95% CI, 1.23-1.70) and 79% higher odds of completing the series on time (aOR = 1.79; 95% CI, 1.11-2.89). CONCLUSION:Adolescent SBHC users had higher odds of completing the HPV vaccine series than adolescents who received all doses in traditional health care settings. SBHCs should be leveraged to increase adolescent immunization rates.

Project description:BACKGROUND:Delayed completion of human papillomavirus vaccination (4vHPV) series is common. We sought to identify factors associated with delay. METHODS:This substudy was part of a large prospective, multi-site study recruiting 9-17?year old girls at the time of their third 4vHPV dose to assess immunogenicity associated with prolonged dosing intervals. At participating sites, parents/legal guardians (caregivers) of all enrolled girls (9-17?years old) and enrolled girls aged 14-17?years were approached for participation. Caregivers completed a questionnaire measuring adolescent and caregiver sociodemographic characteristics, caregiver attitudes and beliefs about on-schedule HPV vaccination and HPV vaccine safety, adolescent's health behaviors, barriers to accessing health care, provider office vaccination practices and a Rapid Estimate of Adult Literacy in Medicine (REALM). Participating girls completed a separate questionnaire measuring their attitudes and beliefs about on-schedule HPV vaccination and HPV vaccine safety. Delay was defined as receiving the third 4vHPV dose >12?months after the first. Bivariate, multinomial logistic regression and multivariate logistic regression analyses were used to identify factors predicting delayed completion. RESULTS:Questionnaires were completed by 482 caregivers and 386 adolescents; 422 caregivers completed a REALM. Delayed 4vHPV dosing occurred in most adolescents (67%). In multivariate analyses, predictors of delayed completion included caregiver demographic factors (self-reported black vs. white race and high school or less education vs. college or more) and an interaction between caregiver's inability to get an immunization appointment as soon as needed and adolescent's type of insurance. CONCLUSIONS:Caregiver's race and educational level, accessibility of immunization appointments, and adolescent's insurance type were found to be related to delays in completion of 4vHPV, but caregiver or adolescent attitudes and beliefs about on-schedule HPV vaccination or HPV vaccine safety were not. Therefore, interventions to improve adherence to recommended vaccination schedules could benefit from a focus on improving access to immunizations. ClinicalTrials.gov (NCT01030562).

Project description:BackgroundCompletion rates among adolescents who initiate the human papillomavirus (HPV) vaccine 3-dose series are low. SMS text message vaccine reminders are effective, but less is known about the best types for HPV series completion or the ability to assess and target vaccine decision-making stage.ObjectiveThe aim of this study is to compare the effectiveness of HPV vaccine series completion in minority adolescents who received precision and educational versus conventional SMS text message reminders.MethodsEnrolled parents of adolescents aged 9-17 years who received the first HPV vaccine dose at 1 of the 4 academic-affiliated community health clinics in New York City were randomized 1:1 to 1 of the 2 parallel, unblinded arms: precision SMS text messages (which included stage-targeted educational information, next dose due date, and site-specific walk-in hours) or conventional SMS text messages without educational information. Randomization was stratified according to gender, age, and language. The primary outcome was series completion within 12 months. In post hoc analysis, enrollees were compared with concurrent nonenrollees and historical controls.ResultsOverall, 956 parents were enrolled in the study. The precision (475 families) and conventional (481 families) SMS text message arms had similarly high series completion rates (344/475, 72.4% vs 364/481, 75.7%). A total of 42 days after the first dose, two-thirds of families, not initially in the preparation stage, moved to preparation or vaccinated stage. Those in either SMS text message arm had significantly higher completion rates than nonenrollees (708/1503, 47.1% vs 679/1503, 45.17%; P<.001). Even after removing those needing only 2 HPV doses, adolescents receiving any SMS text messages had higher completion rates than historical controls (337/2823, 11.93% vs 981/2823, 34.75%; P<.001). A population-wide effect was seen from 2014 to 2016, above historical trends.ConclusionsSMS text message reminders led to timely HPV vaccine series completion in a low-income, urban, minority study population and also led to population-wide effects. Educational information did not provide an added benefit to this population.Trial registrationClinicalTrials.gov NCT02236273; https://clinicaltrials.gov/ct2/show/NCT02236273.

Project description:ImportanceHuman papillomavirus (HPV) vaccination coverage is suboptimal in the US. The association between HPV vaccination requirements for school entry and HPV vaccination coverage remains to be studied.ObjectiveTo examine the association between HPV vaccination school-entry requirements and vaccination initiation in jurisdictions with such vaccination policies (ie, Virginia, the District of Columbia, and Rhode Island) compared with other regions of the US, as determined by the National Center for Chronic Disease Prevention and Health Promotion.Design, setting, and participantsIn a population-based, cross-sectional study, 2017 data from the National Immunization Survey-Teen database were used to determine HPV vaccination initiation. Data from 2008 to 2017 were then examined to assess the association between HPV vaccination school-entry policies and vaccination initiation. Data were obtained for adolescents aged 13 to 17 years in the US with health care professional-reported HPV vaccination histories (cross-sectional study, n = 4784; pre-post policy comparisons, n = 42 431). This study was conducted from May 1, 2019, to March 31, 2020.ExposuresState-level HPV vaccination school-entry requirements from 2008 to 2017.Main outcomes and measuresHealth care professional-confirmed HPV vaccination initiation.ResultsThe 2017 cross-sectional study included 4784 adolescents aged 13 to 17 years (2228 [46.6%] girls; 2556 [53.4%] boys; mean [SD] age, 15.0 [1.4] years; interquartile range, 14-16 years). Compared with nonpolicy jurisdictions within the same region, Rhode Island and the District of Columbia, which have HPV immunization school-entry requirements, had higher levels of HPV vaccination initiation (Rhode Island: adjusted odds ratio [aOR], 4.34; 95% CI, 2.16-10.00; District of Columbia: aOR, 2.35; 95% CI, 1.39-4.19). However, compared with regional nonpolicy states, Virginia's HPV vaccination initiation did not differ significantly (aOR, 1.01; 95% CI, 0.72-1.42). The 2008-2017 pre-post policy comparisons involved 42 431 adolescents aged 13-17 years (22 362 [52.7%] girls; 20 069 [47.3%] boys; mean [SD] age, 15.0 [1.4] years; interquartile range, 14-16 years). Postpolicy levels of HPV vaccination initiation in girls was significantly higher in Rhode Island (aOR, 3.12; 95% CI, 1.92-5.07) than prepolicy values. Similar changes were noted for postpolicy HPV vaccination initiation in boys in the District of Columbia (aOR, 6.36; 95% CI, 4.27-9.46) and Rhode Island (aOR, 5.84; 95% CI, 3.92-8.69) compared with prepolicy measures. With respect to regional nonpolicy states during the same period, both girls and boys in Rhode Island and boys in the District of Columbia experienced larger increases in HPV vaccination initiation. For example, in Rhode Island, boys aged 16 to 17 years had 7.32 (95% CI, 3.56-15.06) times the change in pre-post policy HPV vaccination initiation, while girls aged 16 to 17 years had 1.28 (95% CI, 0.60-2.73) times the change. In the District of Columbia, boys had 6.36 (95% CI, 4.27-9.46) times the change in pre-post policy HPV vaccination initiation.Conclusions and relevanceThe findings of this study suggest that HPV vaccination school-entry requirements are associated with increases in vaccination initiation. Expanding such policies may increase HPV vaccination in the US.

Project description:BackgroundThe Human Papillomavirus (HPV) vaccine has offered a great promise to reduce the cervical cancer burden; its utilization (uptake) however has been lagging. However, the levels and factors associated with the uptake of the vaccine have not been well investigated, especially in the local context.ObjectiveTo assess the uptake of human papillomavirus vaccination and its associated factors among adolescent school girls in ambo town, Oromia, Ethiopia, 2020.MethodsAn institution-based cross-sectional quantitative study design supplemented with the qualitative inquiry was employed to assess Human Papillomavirus vaccination uptake and its associated factors among 422 adolescent school girls in Ambo town, central Ethiopia from December 1-30, 2020. The collected data were coded, entered, and cleaned by using Epi info 7.2.3 and exported to SPSS version 25 for analysis. Descriptive statistics were used to compute summary statistics and proportions. Both bivariate and multivariable logistic regression was employed to identify factors associated with HPV vaccine uptake. Adjusted odds ratio and 95% confidence interval were used for the strength and directions of association. A P-value of < 0.05 was used to declare statistical significance. Qualitative findings have been analyzed with manual thematic analysis.ResultThe proportion of HPV vaccination uptake among school girls in this study was 44.4%. Hearing about HPV vaccine [AOR = 2.50, 95%CI: (1.045-5.959)], availability of awareness creation [AOR = 2.53, 95%CI: (1.507-4.258)], and favorable attitude [AOR = 2.049, 95%CI: (1.153-3.64)] were the key identified factors associated with vaccination uptake. In addition, poor perception, fear of side effects, and misunderstanding were among the major factors identified by qualitative findings.ConclusionThere was low uptake of HPV vaccination among the school Adolescents in the study area. Availability of awareness creation programs, favorable attitude towards HPV vaccine, and hearing about HPV vaccine was significantly associated with the uptake of the HPV vaccination. Therefore, awareness creation and behavior change education are mandatory to scale up the vaccination.

Project description:BackgroundPatient portals are frequently used in modern health care systems as an engagement and communication tool. An increased focus on the potential value of these communication channels to improve health outcomes is warranted.ObjectiveThis paper aimed to quantify the impact of portal use on patients' preventive health behavior and chronic health outcomes.MethodsWe conducted a retrospective, observational cohort study of 10,000 patients aged 50 years or older who were treated at the University of Pennsylvania Health System (UPHS) from September 1, 2014, to October 31, 2016. The data were sourced from the UPHS electronic health records. We investigated the association between patient portal use and patients' preventive health behaviors or chronic health outcomes, controlling for confounders using a novel cardinality matching approach based on propensity scoring and a subsequent bootstrapping method to estimate the variance of association estimates.ResultsPatient-level characteristics differed substantially between portal users, comprising approximately 59.32% (5932/10000) of the cohort, and nonusers. On average, users were more likely to be younger (63.46 years for users vs 66.08 years for nonusers), white (72.77% [4317/5932] for users vs 52.58% [2139/4068] for nonusers), have commercial insurance (60.99% [3618/5932] for users vs 40.12% [1632/4068] for nonusers), and have higher annual incomes (US $74,172/year for users vs US $62,940/year for nonusers). Even after adjusting for these potential confounders, patient portal use had a positive and clinically meaningful impact on patients' preventive health behaviors but not on chronic health outcomes.ConclusionsThis paper contributes to the understanding of the impact of patient portal use on health outcomes and is the first study to identify a meaningful subgroup of patients' health behaviors that improved with portal use. These findings may encourage providers to promote portal use to improve patients' preventive health behaviors.
