目的：确定在短信疫苗提醒中提供疫苗健康素养促进信息是否能提高需要接种两针的儿童在一个季节内接种第二针流感疫苗的接种率和及时性。方法：2012-2013年间，在纽约市3家社区诊所招募符合条件的6个月至8岁儿童首次接种流感疫苗时的家庭。儿童(n=660)被随机分配到“教育”短信组、“常规”短信组和“书面提醒”组。在注册时，所有的武器都收到了一份书面提醒，说明下一剂的截止日期。常规信息包括第二剂到期日和诊所就诊时间。教育信息增加了关于需要及时第二次接种的信息。通过CHI(2)测试评估4月30日之前接受第二剂疫苗的情况。及时性通过在预产期后2周(第42天)使用CHI(2)和随着时间的推移使用Kaplan-Meier分析来评估。结果：大多数家庭都是拉丁裔，并接受了公共保险，组间没有显著差异。教育组的儿童更有可能在4月30日之前接受第二次接种(72.7%)，而传统组(66.7%)和仅接受书面提醒的组(57.1%；P=0.003)相比更有可能接受第二次接种。到第42天(P<；.001)和随着时间的推移(P<；.001)，他们也有更及时的收到。结论：在这个低收入、城市、少数民族人群中，与传统的短信和书面提醒相比，嵌入健康素养信息提高了短信提醒在促进及时接种第二剂流感疫苗方面的有效性。
OBJECTIVE: To determine whether provision of vaccine-health-literacy-promoting information in text message vaccine reminders improves receipt and timeliness of the second dose of influenza vaccine within a season for children in need of 2 doses.METHODS: During the 2012-2013 season, families of eligible 6-month through 8-year-old children were recruited at the time of their first influenza vaccination from 3 community clinics in New York City. Children (n = 660) were randomly assigned to "educational" text message, "conventional" text message, and "written reminder-only" arms. At enrollment, all arms received a written reminder with next dose due date. Conventional messages included second dose due date and clinic walk-in hours. Educational messages added information regarding the need for a timely second dose. Receipt of second dose by April 30 was assessed by using chi(2) tests. Timeliness was assessed by receipt of second dose by 2 weeks after due date (day 42) using chi(2) and over time using a Kaplan-Meier analysis.RESULTS: Most families were Latino and publicly insured with no significant between-arm differences between groups. Children in the educational arm were more likely to receive a second dose by April 30 (72.7%) versus conventional (66.7%) versus written reminder-only arm (57.1%; P = .003). They also had more timely receipt by day 42 (P < .001) and over time (P < .001).CONCLUSIONS: In this low-income, urban, minority population, embedding health literacy information improved the effectiveness of text message reminders in promoting timely delivery of a second dose of influenza vaccine, compared with conventional text messages and written reminder only.
