IntroductionThe HPV vaccine prevents HPV-related cancers and genital warts, which cause significant morbidity and mortality in the US. The vaccine is targeted toward 11–12 year old males and females, but is recommended for “catch-up” vaccination until age 26 for females. Young adult females (18–26 years) represent a unique group that may face distinct barriers to HPV vaccination, one of which is relationship status. The purpose of this study was to assess how relationship status impacts interest in HPV vaccination and primary reasons for non-vaccination among 18–26 year old young adult women.MethodsThe National Health Interview Survey 2010 was examined among unvaccinated females, 18–26 years (N = 1457). A survey-weighted logistic regression analysis with conversion to prevalence ratios assessed how interest in the HPV vaccine (yes/no) was influenced by relationship status (married, living with a partner, other, single) among young adult women. A Rao-Scott chi-square test examined differences between primary reasons for non-vaccination and relationship status among HPV vaccine uninterested women.ResultsAmong unvaccinated women, 31.4% were interested in the HPV vaccine. Women who were living with a partner (PR = 1.45, 95%CI 1.06–1.90) and single (PR = 1.42, 95%CI 1.11–1.76) were significantly more likely than married women to be interested in the HPV vaccine, while controlling for socio-demographic and other known risk factors. Additionally, primary reasons for non-vaccination differed based on relationship status among uninterested women (p < 0.01). Women who were married were more likely to cite not needing the vaccine compared to never married women (p < 0.05).ConclusionRelationship status in young adulthood impacts HPV vaccine interest and decision-making among a national sample of women. Primary reasons for non-interest in the vaccine may be shaped by attitudes and knowledge about the HPV vaccine that differ by relationship status. Future research is needed to elucidate ways to overcome relationship status as a barrier to HPV vaccination. 相似文献

BackgroundEstonia has high cervical cancer incidence and low screening coverage. We modelled the impact of population-based bivalent, quadrivalent or nonavalent HPV vaccination alongside cervical cancer screening.MethodsA Markov cohort model of the natural history of HPV infection was used to assess the cost-effectiveness of vaccinating a cohort of 12-year-old girls with bivalent, quadrivalent or nonavalent vaccine in two doses in a national, school-based vaccination programme. The model followed the natural progression of HPV infection into subsequent genital warts (GW); premalignant lesions (CIN 1–3); cervical, oropharyngeal, vulvar, vaginal and anal cancer. Vaccine coverage was assumed to be 70%. A time horizon of 88 years (up to 100 years of age) was used to capture all lifetime vaccination costs and benefits. Costs and utilities were discounted using an annual discount rate of 5%.ResultsVaccination of 12-year-old girls alongside screening compared to screening alone had an incremental cost-effectiveness ratio (ICER) of €14,007 (bivalent), €14,067 (quadrivalent) and €11,633 (nonavalent) per quality-adjusted life-year (QALY) in the base-case scenario and ranged between €5367–21,711, €5142–21,800 and €4563–18,142, respectively, in sensitivity analysis. The results were most sensitive to changes in discount rate, vaccination regimen, vaccine prices and cervical cancer screening coverage.ConclusionVaccination of 12-year-old girls alongside current cervical cancer screening can be considered a cost-effective intervention in Estonia. Adding HPV vaccination to the national immunisation schedule is expected to prevent a considerable number of HPV infections, genital warts, premalignant lesions, HPV related cancers and deaths. Although in our model ICERs varied slightly depending on the vaccine used, they generally fell within the same range. Cost-effectiveness of HPV vaccination was found to be most dependent on vaccine cost and duration of vaccine immunity, but not on the type of vaccine used. 相似文献

PurposeWe tested the hypotheses that consistency and strength of clinician recommendation of the human papillomavirus (HPV) vaccination would be associated with vaccine delivery rates.MethodsFrom October 2015 through January 2016, we conducted a survey of primary care clinicians (n = 227) in Southeastern Minnesota to evaluate clinician behaviors regarding HPV vaccination. The survey response rate was 41.0% (51 clinical sites). We used the Rochester Epidemiology Project, a clinical data linkage infrastructure, to ascertain clinical site-level HPV vaccination rates. We examined associations of clinician self-reports of both the consistency and strength of their recommendations for HPV vaccination for patients aged 11–12 years (n = 14,406) with site-level vaccination rates.ResultsThe majority of clinicians reported consistently (always or usually) recommending the HPV vaccine to females (79.0%) and to males (62.2%); 71.9% of clinicians reported strongly recommending the vaccine to females while 58.6% reported strongly recommending to males. Consistency and strength of recommending the HPV vaccine was significantly higher among those practicing in pediatrics and board certified in pediatrics compared to family medicine. Higher rates of initiation (1 dose) [Incidence Rate Ratio (IRR) = 1.05; 95% CI (1.01–1.09)] and completion (3 doses) [IRR = 1.08; 95% CI (1.02–1.13)] were observed among clinical sites where, on average, clinicians more frequently reported always or usually recommending the vaccine for females compared to sites where, on average, clinicians reported recommending the vaccine less frequently. Similarly, higher rates of initiation [IRR = 1.03; 95% CI (1.00–1.06)] and completion [IRR = 1.04; CI (1.00, 1.08)] were observed among sites where clinicians reported strongly recommending the vaccine to females more frequently compared to sites where, on average, clinicians reported strongly recommending the HPV vaccine less frequently; similar associations were observed for male initiation [IRR = 1.05; CI (1.02,1.08)] and completion [IRR = 1.05; 95% CI (1.01, 1.09)].ConclusionsConsistency and strength of HPV vaccination recommendation was associated with higher vaccination rates. 相似文献

BackgroundHPV vaccination was recommended by the Advisory Committee on Immunization Practices for young adult females in 2006 and males in 2011 to prevent HPV-related cancers and genital warts. As this prevention mechanism continues to disseminate, it is necessary to monitor the uptake of this vaccine. College students represent an important population for HPV vaccination efforts and surveillance due to increased risk for HPV infection and representing a priority population for catch-up HPV vaccination. The purpose of this study was to assess the trends in HPV vaccination among U.S. college females and males from 2009 to 2013, and to examine whether predictors for HPV vaccination differ between males and females.MethodsThe National College Health Assessment-II (Fall 2009–2013) was used to assess trends in HPV vaccination using hierarchical logistic regression across genders and demographics. Data from 2013 were used to assess demographic variables associated with HPV vaccination for males and females, respectively. The analysis was conducted in 2015.ResultsFemales had nearly double the rates of HPV vaccination compared to males over time. All demographic sub-groups had significant increases in vaccine rates over time, with select male sub-groups having more accelerated increases (e.g., gay). Young age (18–21 vs. 22–26 years) was a significant predictor for HPV vaccination among males and females, while race/ethnicity was a predictor of vaccination among females only.ConclusionsThese findings identified specific demographic sub-groups that need continued support for HPV vaccination. Campus health centers may be rational settings to facilitate clinical opportunities for HPV vaccination among unvaccinated college students. 相似文献

BackgroundThe 9-valent HPV (9vHPV) vaccine was developed to prevent infection and disease related to 9 HPV types (HPV6/11/16/18/31/33/45/52/58) which cause approximately 90% of cervical cancers, HPV-related vulvar, vaginal and anal cancers, and genital warts worldwide. In a pivotal efficacy study, the 9vHPV vaccine prevented infection and disease due to the 9 vaccine types. Duration of protection remains to be determined. Vaccines that induce long-term protection are generally characterized by the generation of immune memory. The purpose of this report is to assess the persistence of HPV antibody response and existence of immune memory at 5 years post-vaccination.MethodsA subset of subjects (N = 150) who received 3 doses of 9vHPV vaccine at day 1, month 2 and month 6 in the pivotal efficacy study continued in a study extension and received a fourth dose of 9vHPV vaccine at month 60. Serum HPV antibody levels were measured pre-dose 4 and at 7 and 28 days post-dose 4 by competitive Luminex immunoassay. Adverse events were assessed using a vaccination report card.ResultsHPV antibodies induced following the 3-dose series of 9vHPV vaccine in the base study persisted through month 60 with seropositivity rates ranging from 77.5% to 100%. Geometric mean titers at 1 week and 1 month post-dose 4 were 1.25–4.10 and 1.65–4.88-fold higher, respectively, than levels observed 1 month following the completion of the three-dose primary series. Seropositivity rates were >99% and 100% at 1 week and 1 month post-dose 4, respectively. The fourth dose of 9vHPV vaccine was generally well tolerated.ConclusionsA three-dose regimen of the 9vHPV vaccine induced persistent HPV antibody response through 5 years post-vaccination. Administration of a fourth dose resulted in a strong anamnestic response to all 9 vaccine types. These findings suggest that the efficacy of the 9vHPV vaccine will be long lasting.Clinical Trials.gov Identifier: NCT00543543. 相似文献

BackgroundAustralia commenced a publically-funded, National Human Papillomavirus (HPV) Vaccination Program in 2007 with a two year catch-up phase for females aged 12–26 years.ObjectiveTo identify the factors associated with the uptake of the HPV vaccine (which has a recommended 3-dose schedule in Australia) by young adult women vaccinated by general practitioners and community-based programs within the catch-up phase.Methods1139 women who were eligible to receive the free HPV vaccine during the catch-up period were recruited in 2008–2009 (age 20–29 years at recruitment), in New South Wales, after having a normal (negative) cervical smear result recorded on the NSW Pap Test Register. Participants completed a self-administered questionnaire providing information on vaccination status, and sociodemographic and other factors.ResultsOverall, 880 (77%) women reported receiving ≥1 dose of the vaccine and 777 women (68%) reported receiving ≥2 doses. In multivariable analysis (adjusting for the period for which each woman was eligible for free HPV vaccination), uptake of ≥1 dose of the vaccine was significantly associated with being born in Australia (p < 0.01), being single (p = 0.02), being nulliparous (p < 0.01), living in a higher socioeconomic status area (p-trend = 0.03), living in more remote areas (p = 0.03), drinking alcohol (p < 0.01) and using hormonal contraceptives (p < 0.01). Although vaccinated women were more likely to have fewer sexual partners than unvaccinated women (p-trend = 0.02), they were also more likely to report a prior sexually transmitted infection (STI) (p = 0.03). Similar factors were associated with receiving ≥2 doses.ConclusionsIn this group, women living in higher socioeconomic status areas were more likely to be vaccinated against HPV in the catch-up phase of the national program. Although vaccinated women tended to have fewer sexual partners, they also reported prior STIs, which may be a marker of increased risk of prior exposure to HPV. The findings of this study reinforce the continuing need to prioritise equitable delivery of vaccination to various population subgroups. 相似文献

IntroductionThis study aimed to evaluate the early population impact of Ontario’s school-based human papillomavirus (HPV) vaccination program, implemented in September 2007 for grade 8 females, by comparing anogenital wart (AGW) health care utilization before and after vaccine program implementation, in program-eligible and program-ineligible cohorts, focusing on 15–26 year olds.MethodsUsing a retrospective longitudinal population-based study design, health administrative data were used to identify incident AGWs and total health service utilization (HSU) for AGWs for Ontario residents 15 years and older between April 1 2004 and March 31 2014. The study period was divided into two eras: the pre-vaccine program era and the vaccine program era. Negative binomial models were generated to analyze trends across time by age group and sex. We adjusted female rates for routine Papanicolaou (Pap) testing to address spillover effects of Pap smear policy changes on AGW diagnosis.ResultsBetween fiscal years 2004 and 2013, AGW incidence decreased 2.6% on average per year in 15–17 year old females, and total HSU for AGWs decreased an average of 4.8% and 2.2% per year in 15–17 and 18–20 year old females. Comparing the vaccine era to the pre-vaccine era, AGW incidence decreased 6.5% in 18–20 year old females, and AGW HSU decreased 13.8%, 11.1%, and 10.0% in 15–17, 18–20, and 21–23 year old females respectively. In contrast, male AGW incidence rates increased an average of 4.1%, 2.8%, and 0.9% per year in 15–17, 21–23, and 24–26 year old males respectively. AGW incidence rates increased 12.2% in 15–17 year old males from the pre-vaccine to vaccine era.ConclusionThe decline in AGW incidence and HSU in program-eligible females suggests the school-based HPV vaccination program has had an early population impact in Ontario. The increasing AGW incidence in males suggests no early evidence of herd effects in males. 相似文献

ObjectivesTo assess the safety and immunogenicity of the investigational 9-valent (6/11/16/18/31/33/45/52/58) HPV (9vHPV) vaccine in prior recipients of a 3-dose regimen of quadrivalent (6/11/16/18) HPV (qHPV) vaccine.MethodsV503-006 was a randomized, double-blinded, safety/tolerability and immunogenicity study of the 9vHPV vaccine in females 12–26 years of age who were previously vaccinated with qHPV vaccine. Subjects were randomized in a 2:1 ratio to receive 3 doses of 9vHPV vaccine (n = 618) or saline placebo (n = 306) at day 1, month 2, and month 6. Systemic, injection-site and serious adverse experiences (AEs) were monitored. Serum samples were collected at day 1, month 2, and month 7. Anti-HPV 6/11/16/18/31/33/45/52/58 titers were measured using the 9-valent HPV competitive Luminex Immunoassay (cLIA).ResultsThe frequency of injection-site AEs (days 1–5 following any vaccination) was higher in the 9vHPV vaccine group than in the placebo group (91.1% and 43.9%, respectively). The frequencies of vaccine-related systemic AEs (days 1–15 following any vaccination) were generally comparable between the 2 groups (30.6% in the 9vHPV vaccine group, and 25.9% in the placebo group). One vaccine-related serious AE was reported in each of the 9vHPV vaccine and placebo groups. Few subjects (9vHPV = 0.5%; placebo = 0%) discontinued due to an AE. At 4 weeks post-dose 3, over 98% of subjects in the 9vHPV vaccine group were seropositive for HPV types 31/33/45/52/58, with marked elevations in cLIA geometric mean titers (GMTs) to these HPV types. Anti-HPV 31/33/45/52/58 GMTs were lower than in subjects administered 9vHPV vaccine who had not previously received qHPV vaccine (based on cross-study analyses); the clinical significance of this difference is unknown.ConclusionsAdministration of a 3-dose regimen of 9vHPV vaccine to adolescent girls and young women 12–26 years of age who are prior qHPV vaccine recipients is highly immunogenic with respect to HPV types 31/33/45/52/58 and generally well tolerated. 相似文献

Australia commenced an ongoing school based government funded human papillomaviruses (HPV) (cervical cancer prevention) vaccination program in April 2007 for adolescent females aged 12–13 years. In addition, up to December 31, 2009, a catch-up program for young females 13–26 years of age was offered: a school-based vaccination program was used to offer HPV vaccine to girls enrolled in school (14–17 years), and general practitioners or other community health provider offered vaccine to young women aged 18–26 years. To date, only the quadrivalent vaccine (HPV 6/11/16/18) has been utilized in the funded program. Acceptance of the vaccine is high with coverage of 3 doses of the HPV vaccine in the school age cohort around 70%, and just over 30% in the older age cohort. Since the vaccination program was initiated, a reduction in new cases of genital warts of 73% among vaccine eligible age females has been evidenced in STI clinics across Australia. A reduction of 44% of new cases in young males (not a part of the free program) was also documented during this same time period, suggesting significant herd immunity. Similarly, in the state of Victoria, a small but significant decrease in high grade abnormalities in Pap screening findings has been reported in young women < 18 years for the period 2007–9, as compared to pre-vaccination. Challenges for the future include how we can sustain and improve HPV vaccination coverage in young Australian women, while maintaining cervical cancer screening participation and reviewing cervical cancer screening methods. 相似文献

HPV vaccine awareness and the association of trust in cancer information from physicians among males
《Vaccine》2017,35(20):2661-2667
IntroductionBlack and Hispanic men are diagnosed with more HPV-related cancers and at later stages compared to other racial/ethnic groups. Physician communication with men about HPV vaccination may be beneficial to increasing HPV vaccinations and decreasing HPV transmission. The purpose of this study was to examine HPV and HPV vaccine awareness among men by race, and the association between trust in cancer information from physicians and ever hearing about HPV and the HPV vaccine.MethodsU.S. adult males (age 18+) were identified from the 2014 Health Information National Trends Survey (HINTS) (n = 1203). Binomial logistic regression models assessed the influences of race/ethnicity and trust of cancer information from physicians on men having heard of HPV and the HPV vaccination.ResultsApproximately 50% of the sample had never heard of HPV and 53% had never heard of the vaccine. Black men were less likely to know that HPV is sexually transmitted compared to White and Hispanic men (p < 0.001). Hispanic and Black men were less likely to have heard about the HPV vaccine when compared to White men (p < 0.001). Additionally, Hispanic men were less likely to trust a doctor about cancer information compared to White and Black men (p < 0.001).ConclusionFindings highlight the lack of awareness about HPV among men. Furthermore, statistically significant racial/ethnic differences were found in HPV vaccine knowledge and trust in receiving cancer information from physicians. Future interventions should include community-based approaches and improved physicians’ HPV-related communication to increase knowledge and uptake of the HPV vaccine. 相似文献

PurposeWe tested the hypothesis that clinician knowledge, clinician barriers, and perceived parental barriers relevant to the human papillomavirus (HPV) vaccination account for the variation in vaccine delivery at the practice-site level.MethodsWe conducted a survey from October 2015 through January 2016 among primary care clinicians (n = 280) in a 27-county geographic region to assess clinician knowledge, clinician barriers, and perceived parental barriers regarding HPV vaccination. Primary care clinicians included family medicine physicians, general pediatricians, and family and pediatric nurse-practitioners. We also used the Rochester Epidemiology Project to measure HPV vaccination delivery. Specifically we used administrative data to measure receipt of at least one valid HPV vaccine dose (initiation) and receipt of three valid HPV vaccine doses (completion) among 9–18 year old patients residing in the same 27-county geographic region. We assessed associations of clinician survey data with variation in vaccine delivery at the clinical site using administrative data on patients aged 9–18 years (n = 68,272).ResultsConsistent with our hypothesis, we found that greater knowledge of HPV and the HPV vaccination was associated with higher rates of HPV vaccination initiation (Incidence rate ratio [IRR] = 1.05) and completion of three doses (IRR = 1.28). We also found support for the hypothesis that greater perceived parental barriers to the HPV vaccination were associated with lower rates of initiation (IRR = 0.94) and completion (IRR = 0.90). These IRRs were statistically significant even after adjustment for site-level characteristics including percent white, percent female, percent ages 9–13, and percent with government insurance or self-pay at each site.ConclusionsClinician knowledge and their report of the frequency of experiencing parental barriers are associated with HPV vaccine delivery rates—initiation and completion. Higher measures of knowledge correlated with higher rates. Fewer perceived occurrences of parental barriers correlated with lower rates. These data can guide efforts to improve HPV vaccine delivery in clinical settings. 相似文献

BackgroundA nine-valent human papilloma virus (9vHPV) vaccine has been developed to prevent infections and diseases related to HPV 6/11/16/18 (as per the licensed quadrivalent HPV (qHPV) vaccine) as well as to five additional oncogenic HPV types (HPV 31/33/45/52/58). The 9vHPV vaccine has the potential to prevent 90% of cervical cancers, HPV-related anal, vaginal and vulval cancers and anogenital warts. We compared the immunogenicity and safety of the 9vHPV vaccine versus the qHPV vaccine in 16–26-year-old men.MethodsParticipants (N = 500) were randomised to receive 9vHPV or qHPV vaccines on day 1, month 2 and month 6. Serology testing was performed on day 1 and month 7. HPV type-specific antibody titres (anti-HPV 6/11/16/18/31/33/45/52/58) were determined by competitive Luminex immunoassay and expressed as geometric mean titres and seroconversion rates. Vaccine safety was also assessed.ResultsThe HPV 6/11/16/18 immune responses elicited by the 9vHPV vaccine were comparable with those elicited by the qHPV vaccine. All participants receiving the 9vHPV vaccine seroconverted for HPV 31/33/45/52/58. The 9vHPV and qHPV vaccines showed comparable safety profiles.ConclusionsIn addition to immune responses to HPV 31/33/45/52/58, a three-dose regimen of the 9vHPV vaccine elicited a similar immune response to HPV 6/11/16/18 when compared with the qHPV vaccine in men aged 16–26 years. The safety profile was also similar for the two vaccines. The results from this study support extending the efficacy findings with qHPV vaccine to 9vHPV vaccine in men aged 16–26 years.NCT02114385 相似文献

BackgroundReceiving a healthcare provider's recommendation is a strong predictor of HPV vaccination, but little is known empirically about which types of recommendation are most influential. Thus, we sought to investigate the relationship between recommendation quality and HPV vaccination among U.S. adolescents.MethodsIn 2014, we conducted a national, online survey of 1495 parents of 11–17-year-old adolescents. Parents reported whether providers endorsed HPV vaccination strongly, encouraged same-day vaccination, and discussed cancer prevention. Using an index of these quality indicators, we categorized parents as having received no, low-quality, or high-quality recommendations for HPV vaccination. Separate multivariable logistic regression models assessed associations between recommendation quality and HPV vaccine initiation (≥1 dose), follow through (3 doses, among initiators), refusal, and delay.ResultsAlmost half (48%) of parents reported no provider recommendation for HPV vaccination, while 16% received low-quality recommendations and 36% received high-quality recommendations. Compared to no recommendation, high-quality recommendations were associated with over nine times the odds of HPV vaccine initiation (23% vs. 74%, OR = 9.31, 95% CI, 7.10–12.22) and over three times the odds of follow through (17% vs. 44%, OR = 3.82, 95% CI, 2.39–6.11). Low-quality recommendations were more modestly associated with initiation (OR = 4.13, 95% CI, 2.99–5.70), but not follow through. Parents who received high- versus low-quality recommendations less often reported HPV vaccine refusal or delay.ConclusionsHigh-quality recommendations were strongly associated with HPV vaccination behavior, but only about one-third of parents received them. Interventions are needed to improve not only whether, but how providers recommend HPV vaccination for adolescents. 相似文献

PurposeLittle is known about how the number of HPV vaccine doses affect adherence to screening guidelines. This study compared adherence to cervical cancer screening by the number of HPV vaccine doses received by young women and assessed whether the specialty of vaccinating providers affected behavior.MethodsThis retrospective cohort study using administrative insurance claims records included 24,964 19–26 year old women who received at least 1 injection of the HPV vaccine between January 2006 and November 2009. Vaccinated young women continuously enrolled in a nationally-representative private insurance plan for 6 months prior to and 37 months after HPV vaccine administration were included. Logistic regression was used to compare the odds of Papanicolaou (Pap) testing 3 years after vaccine initiation by number of vaccine doses and provider type.ResultsIn this sample, 79.3% had a Pap test 3 years following vaccine initiation. Receiving 1 (aOR: 0.60, 95% CI 0.55–0.65) or 2 (aOR: 0.80, 95% CI 0.74–0.87) doses was associated with decreased odds of Pap testing compared to 3 doses. Many young women in our sample (16.5%) were diagnosed with cervical dysplasia prior to HPV vaccination. Patients vaccinated by non-obstetrician/gynecologists were less likely to get a Pap test following vaccination.ConclusionsWomen who received 1 or 2 doses of the HPV vaccine were less likely than those who received 3 doses to be screened for cervical cancer 3 years following vaccine initiation. Pediatricians and primary care physicians should convey the importance of initiating and continuing screening to HPV vaccinated patients. 相似文献

BackgroundMany youth with special health care needs (YSHCN) have not received recommended adolescent vaccines, yet data are lacking on correlates of vaccination among this population. Such information can identify subgroups of YSHCN that may be at risk for under-immunization and strategies for increasing vaccination.MethodsWe analyzed weighted data from a population-based sample of parents with an 11- to 17-year-old child with a special health care need from the 2010–2012 North Carolina Child Health Assessment and Monitoring Program (n = 604). We used ordinal logistic regression to identify correlates of how many recommended vaccines (tetanus booster, meningococcal, and HPV [at least one dose] vaccines) adolescents had received.ResultsOnly 12% of YSHCN (18% of females and 7% of males) had received all three vaccines. More YSHCN had received tetanus booster vaccine (91%) than meningococcal (28%) or HPV vaccines (32%). In multivariable analyses, YSHCN who were female (OR = 2.59, 95% CI: 1.57–4.24), ages 16–17 (OR = 2.06, 95% CI: 1.10–3.87), or who had a preventive check-up in the past year (OR = 2.98, 95% CI: 1.24–7.21) had received a greater number of the vaccines. YSHCN from households that contained a person with at least some college education had received fewer of the vaccines (OR = 0.57, 95% CI: 0.33–0.96). Vaccine coverage did not differ by type of special health care need.ConclusionsVaccine coverage among YSHCN is lacking and particularly low among those who are younger or male. Reducing missed opportunities for vaccination at medical visits and concomitant administration of adolescent vaccines may help increase vaccine coverage among YSHCN. 相似文献

ObjectiveWe describe provider documented counseling patterns and perception regarding HPV vaccination among patients with a history of cervical dysplasia.MethodsAll patients ages 21–45 who underwent colposcopy at a single academic medical center from 2018 to 2020 were sent a self-administered survey through the electronic medical record patient portal to assess their attitudes regarding human papillomavirus (HPV) vaccination. Demographic information, HPV vaccination history, and documented obstetrics and gynecology provider counseling at the time of colposcopy were examined.ResultsOf 1465 patients, 434 (29.6 %) reported or had documented receipt of at least one dose of the human papillomavirus vaccine. The remainder reported they were not vaccinated or had no documentation of vaccination. Proportion of vaccinated patients was higher among White compared to Black and Asian patients (P = 0.02). On multivariate analysis, private insurance (aOR 2.2, 95 % CI 1.4–3.7) was associated with vaccinated status while Asian race (aOR 0.4, 95 % CI 0.2–0.7) and hypertension (aOR 0.2, 95 % CI 0.08–0.7) were less likely to be associated with vaccination status. Among patients with unvaccinated or unknown vaccination status, 112 (10.8 %) received documented counseling regarding catch-up human papillomavirus vaccination at a gynecologic visit. Patients seen by a sub-specialist obstetrics and gynecologic provider were more likely to have documented provider counseling regarding vaccination compared to those seen by a generalist obstetric/gynecologist provider (26 % vs 9.8 %, p < 0.001). Patients cited lack of physician discussion (53.7 %) and the belief that they were too old to receive the HPV vaccine (48.8 %) as the main reasons for remaining unvaccinated.ConclusionHPV vaccination and the rate of obstetric and gynecologic provider counseling regarding HPV vaccination among patients undergoing colposcopy remains low. When surveyed, many patients with a history of colposcopy cited provider recommendation as a factor in their decision to undergo adjuvant HPV vaccination, demonstrating the importance of provider counseling in this group. 相似文献

BackgroundBetween 2010 and 2014, the percentage of 13–17 year-old girls administered ≥3 doses of the human papilloma virus (HPV) vaccine (“fully vaccinated”) increased by 7.7 percentage points to 39.7%, and the percentage not administered any doses of the HPV vaccine (“not immunized”) decreased by 11.3 percentage points to 40.0%.ObjectiveTo evaluate the complex interactions between parents’ vaccine-related beliefs, demographic factors, and HPV immunization status.MethodsVaccine-related parental beliefs and sociodemographic data collected by the 2010 National Immunization Survey-Teen among teen girls (n = 8490) were analyzed. HPV vaccination status was determined from teens’ health care provider (HCP) records.ResultsAmong teen girls either unvaccinated or fully vaccinated against HPV, teen girls whose parent was positively influenced to vaccinate their teen daughter against HPV were 48.2 percentage points more likely to be fully vaccinated. Parents who reported being positively influenced to vaccinate against HPV were 28.9 percentage points more likely to report that their daughter's HCP talked about the HPV vaccine, 27.2 percentage points more likely to report that their daughter's HCP gave enough time to discuss the HPV shot, and 43.4 percentage points more likely to report that their daughter's HCP recommended the HPV vaccine (p < 0.05). Among teen girls administered 1–2 doses of the HPV vaccine, 87.0% had missed opportunities for HPV vaccine administration.ConclusionResults suggest that an important pathway to achieving higher ≥3 dose HPV vaccine coverage is by increasing HPV vaccination series initiation though HCP talking to parents about the HPV vaccine, giving parents time to discuss the vaccine, and by making a strong recommendation for the HPV. Also, HPV vaccination series completion rates may be increased by eliminating missed opportunities to vaccinate against HPV and scheduling additional follow-up visits to administer missing HPV vaccine doses. 相似文献

BackgroundVaccination has been suggested to be involved in the aetiology of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). HPV vaccine was introduced in the Norwegian Childhood Immunisation Programme and offered 12 year old girls from 2009. We studied the association between HPV vaccination and risk of CFS/ME and also assessed medical history in relation to both risk of CFS/ME and HPV vaccine uptake.MethodsIndividual data from national registries, including the Norwegian Population Registry, the Norwegian Patient Registry and the Norwegian Immunisation Registry were linked using the unique personal identification number. Yearly incidence rates of CFS/ME for 2009–2014 were calculated among the 824,133 boys and girls, aged 10–17 living in Norway during these 6 years. A total of 176,453 girls born 1997–2002 were eligible for HPV vaccination and included in further analyses. Hazard ratios (HRs) of CFS/ME were estimated using Cox regression. Risk differences (RDs) of vaccine uptake were estimated with binomial regression.ResultsA similar yearly increase in incidence rate of CFS/ME was observed among girls and boys, IRR = 1.15 (95% confidence interval (CI) 1.10–1.19) and 1.15 (95% CI 1.09–1.22), respectively. HPV vaccination was not associated with CFS/ME, HR = 0.86 (95% CI 0.69–1.08) for the entire follow-up period and 0.96 (95% CI 0.64–1.43) for the first two years after vaccination. The risk of CFS/ME increased with increasing number of previous hospital contacts, HR = 5.23 (95% CI 3.66–7.49) for 7 or more contacts as compared to no contacts. Girls with 7 or more hospital contacts were less likely to be vaccinated than girls with no previous hospital contacts, RD = −5.5% (95% CI −6.7% to −4.2%).ConclusionsNo indication of increased risk of CFS/ME following HPV vaccination was observed among girls in the first 6 birth cohorts offered HPV vaccine through the national immunisation programme in Norway. 相似文献
