背景：流感疫苗接种覆盖率很低，特别是在低收入人群中。大多数疫苗通常在流感季节早期接种，但持续的疫苗接种努力对于实现最佳覆盖率至关重要。最近，短信流感疫苗接种提醒的影响在低收入人群中得到了展示。对延迟接种流感疫苗的儿童或最有效的消息类型的影响知之甚少。目的：确定教育加互动短信提醒对晚秋未接种的城市低收入儿童流感疫苗接种的影响。设计：随机对照试验。设置/参与者：来自四个学术附属儿科诊所的5462名6个月-17岁儿童的父母在2011年11月中旬之前未接种疫苗。干预：符合条件的父母按孩子的年龄和儿科诊所地点分层，并按1：1：1分配到教育加互动短信提醒、仅教育短信提醒或常规护理。使用与免疫登记关联的短信系统，干预儿童的父母每周最多收到七条短信提醒。在教育加互动短信臂中发送给家长的其中一条消息允许选择更多关于流感和流感疫苗接种的信息。主要观察指标：2012年3月31日之前接种流感疫苗。收集和分析了2012-2014年间的数据。结果：大多数儿童都有公共保险，会说西班牙语。不同组之间的基线人口统计数据相似。教育短信+互动短信组家长的儿童接种率(38.5%)高于单纯教育短信组(35.3%；差异=3.3%，95%CI=0.02%，6.5%；相对风险比=1.0 9，95%CI=1.002，1.19)和常规护理组(34.8%；差异=3.8%，95%CI=0.6%，7.0%；RRR=1.11，95%CI=1.02-1.21)ARM。结论：嵌入教育信息和互动选项的短信提醒对晚秋仍未接种疫苗的城市低收入少数民族儿童流感疫苗接种有一定的积极作用。(C)《2015美国预防医学杂志》
Background: Influenza vaccination coverage is low, especially among low-income populations. Most doses are generally administered early in the influenza season, yet sustained vaccination efforts are crucial for achieving optimal coverage. The impact of text message influenza vaccination reminders was recently demonstrated in a low-income population. Little is known about their effect on children with delayed influenza vaccination or the most effective message type.Purpose: To determine the impact of educational plus interactive text message reminders on influenza vaccination of urban low-income children unvaccinated by late fall.Design: Randomized controlled trial.Setting/participants: Parents of 5,462 children aged 6 months-17 years from four academically affiliated pediatric clinics who were unvaccinated by mid-November 2011.Intervention: Eligible parents were stratified by their child's age and pediatric clinic site and randomized using a 1:1:1 allocation to educational plus interactive text message reminders, educational-only text message reminders, or usual care. Using an immunization registry-linked text messaging system, parents of intervention children received up to seven weekly text message reminders. One of the messages sent to parents in the educational plus interactive text message arm allowed selection of more information about influenza and influenza vaccination.Main outcome measures: Influenza vaccination by March 31, 2012. Data were collected and analyzed between 2012 and 2014.Results: Most children were publicly insured and Spanish speaking. Baseline demographics were similar between groups. More children of parents in the educational plus interactive text message arm were vaccinated (38.5%) versus those in the educational-only text message (35.3%; difference=3.3%, 95% CI=0.02%, 6.5%; relative risk ratio (RRR)=1.09, 95% CI=1.002, 1.19) and usual care (34.8%; difference=3.8%, 95% CI=0.6%, 7.0%; RRR=1.11, 95% CI=1.02-1.21) arms.Conclusions: Text message reminders with embedded educational information and options for interactivity have a small positive effect on influenza vaccination of urban, low-income, minority children who remain unvaccinated by late fall.
