目的：评价计算机生成电话提醒和召回信息在提高学龄前儿童免疫接种率中的作用。设计：随机对照试验。环境：佐治亚州城市和农村的14个县。研究对象：小于2岁的儿童（N=8002）；将电话号码列入已有的计算机免疫数据库；在4个月的登记期内，按时或迟于免疫接种。干预：儿童家庭被随机分组，在孩子预产期前一天接收或不接收普通或特定疫苗的计算机生成的电话提醒或召回信息，如果孩子迟到，则在随机分组后立即接收。主要结局指标：30天随访期间的免疫接种率。结果：4636名家庭随机接收信息的儿童中，1684名（36.3%）在30天内到卫生部门就诊，而3366名家庭未接触的儿童中有955名（28.4%）在30天内就诊(风险比[RR]=1.28； 95%可信区间[CI]=1.20 ~ 1.37
Objective: To assess the effectiveness of computer-generated telephone reminder and recall messages in increasing preschool immunization visits.Design: Randomized, controlled trial. Setting: Fourteen counties in urban and rural Georgia.Study Participants: Children (N=8002) who were younger than 2 years; had telephone numbers listed in preexisting computerized immunization databases; and were due or late for immunization(s) during the 4-month enrollment period.Intervention: Households of children were randomized to receive or not receive a general or vaccine-specific computer-generated telephone reminder or recall message the day before the child was due, or immediately after randomization if the child was late.Main Outcome Measure: The rates of immunization visits during the 30-day follow-up period.Results: Of the 4636 children whose households were randomized to receive a message, 1684 (36.3%) visited the health department within 30 days compared with 955 (28.4%) of the 3366 children whose households were not contacted (risk ratio [RR]=1.28; 95% confidence interval [CI]=1.20 to 1.37; P
