ObjectivesTo investigate the association between providing leaflets to support pediatricians in explaining the safety of the human papillomavirus (HPV) vaccine and mother’s decision to vaccinate their daughters in Japan.MethodsIn this cross-sectional study, we conducted a survey of mothers to evaluate the effect of leaflets that were created to support pediatricians in explaining the safety profile of the HPV vaccine. Mothers who provided consent for vaccination before receiving an explanation were excluded from the study. The primary outcome was the mother’s decision to vaccinate their daughters with the HPV vaccine after receiving an explanation from pediatricians using our leaflets.ResultsAmong 161 eligible mothers, 101 decided on HPV vaccination (decided group) and 60 did not (decided against group). There was no difference in the maternal background between the 2 groups. The decided group had a significantly more positive impression of the leaflets than the undecided group. In multivariable logistic regression analysis, a detailed explanation for possible adverse events and specific solutions to them was associated with the mother's decision to have their daughters vaccinated (odds ratio 2.35, 95% confidence interval 1.02–5.44), but not the pathology of cervical cancer and the HPV vaccination process.ConclusionLeaflets emphasizing an explanation of adverse events may contribute to mothers’ decision making for HPV vaccination. 相似文献

BackgroundGSK initiated a Pregnancy Registry in the United States (US) for the reduced-antigen-content tetanus-diphtheria-acellular pertussis (Tdap; Boostrix, GSK) vaccine with the aim to detect and describe pregnancy outcomes in women vaccinated with Boostrix 28 days before estimated conception or during pregnancy.MethodsVoluntary reports of pregnancy exposure to Boostrix received from spontaneous and post-marketing surveillance sources in the US were assessed. Reports were classified as prospective or retrospective based on the knowledge of pregnancy outcomes at the time of reporting. For completeness, reports of exposure to Boostrix or to the Tdap-inactivated poliovirus vaccine (Boostrix-IPV, GSK) reported to the global safety database from countries outside the US were also evaluated.ResultsFrom May 2005 to August 2019, 1517 (1455 prospective and 62 retrospective) pregnancy reports were received in the Boostrix US Pregnancy Registry. Of the prospective reports, 250 had known outcomes: 244 live infants with no apparent birth defects (BDs), three live infants with BDs, and three spontaneous abortions with no apparent BDs. Of the retrospective reports, 55 had known outcomes: 33 live infants with no apparent BDs, 16 live infants with BDs, one spontaneous abortion with no apparent BDs, four stillbirths with no apparent BDs, and one stillbirth with BDs. Cumulatively, 1321 pregnancy reports (1006 for Boostrix; 315 for Boostrix-IPV) were received from countries outside the US. Of these, 163 prospective reports and 551 retrospective reports had known outcomes. Results were in line with those from the Boostrix US Pregnancy Registry.ConclusionsData currently available from the Boostrix US Pregnancy Registry and from countries outside the US suggested that exposure to Boostrix or Boostrix-IPV during pregnancy does not raise safety concerns related to adverse pregnancy outcomes or BDs. 相似文献

背景 人口老龄化趋势下,罹患多种慢性病的失能或半失能老年人对居家医疗护理服务需求迫切,但基层医务人员提供居家医疗护理服务存在较大的医疗风险和安全隐患,加强居家医疗护理服务的安全管理,有利于提高基层医务人员提供居家医疗护理服务的意愿。 目的 调查基层医疗卫生机构对居家护理服务的安全支持情况和医务人员的服务意愿,为进一步推动居家医疗护理服务发展提供参考依据。 方法 2021年8—10月,采用便利抽样法在四川省五大经济区抽取49所基层医疗卫生机构的1 131例医务人员。自行设计调查问卷,以"问卷星"电子问卷的形式收集资料。问卷内容包括医务人员的一般情况(8个条目)、提供居家医疗护理服务的经历(2个条目)、医疗机构对医务人员的安全支持(7个条目)、医务人员的居家医疗护理服务意愿(1个条目)。比较不同特征医务人员提供居家医疗护理服务的意愿,采用二元Logistic回归分析医务人员提供居家医疗护理服务意愿的影响因素。 结果 1 131例基层医务人员中,692例(61.18%)报告有过居家医疗护理服务的经历,193例(17.06%)报告在服务过程中发生过不良事件/安全事件,531例(46.95%)报告其所在医疗机构未评估过患者接受居家医疗护理服务的安全风险,199例(17.60%)表示所在机构评估了医务人员提供居家医疗护理服务的安全风险,299例(26.44%)在居家医疗护理服务过程中使用APP定位系统,273例(24.14%)由机构配备报警、延迟预警等设备,807例(71.35%)表示居家医疗护理服务过程中没有获得所在机构内其他医务人员的支持措施,303例(26.79%)表示机构曾组织居家医疗护理服务的专项研讨活动,352例(31.12%)表示接受过有关居家医疗护理服务专项培训,853例(75.42%)表示愿意提供居家医疗护理服务。二元Logistic回归分析结果显示,就职的基层医疗卫生机构类型,目前受聘的专业技术职称,医疗机构是否评估过患者接受居家医疗护理服务的安全风险,在居家医疗护理服务过程中是否配备报警、延迟预警等设备,是否参加过有关居家医疗护理服务的专项培训,对医务人员提供居家医疗护理服务意愿有影响(P<0.05)。 结论 现阶段居家医疗护理服务的安全支持不足,多种因素影响基层医务人员提供居家医疗护理服务的意愿。基层医疗卫生机构应加强对患者接受居家医疗护理服务安全风险的评估,为提供居家医疗护理服务的医务人员配备报警、延迟预警等设备,积极举办居家医疗护理服务相关的专项培训并鼓励医务人员参加,以降低医务人员提供居家医疗护理服务的风险,保障其人身安全。 相似文献
