文摘目的报告北京市2014年学龄前流动儿童选择性补充免疫活动（Selective Supplementary Immunization Activities,S-SIA）质量和效果评价结果。方法选择2014年1月1日-3月21日报告了≥2例8月龄-14岁麻疹病例的14个街道,由第三方派出现场人员入户调查,并实时传输调查数据。市疾病预防控制中心专业人员通过网络和电话提供实时技术支持,并汇总评估结果。根据批质量保证抽样法,在14个街道通过多阶段抽样抽取学龄前流动儿童45名,核查其在北京市儿童预防接种信息管理系统（Beijing Children Immunization Information Management System,BCIIMS）在管状态、预防接种证和口服脊髓灰质炎减毒活疫苗第1-3剂、含麻疹成分疫苗（Measles-containing Vaccine,MCV）第1、2剂,及脑膜炎球菌多糖疫苗、无细胞百日咳-白喉-破伤风联合疫苗、乙型肝炎疫苗（Hepatitis B Vaccine,Hep B）、流行性乙型脑炎减毒活疫苗第1剂接种率。调查全程均严格质量控制,并收集过程和结果数据进行调查质量评价和数据分析。结果共调查21 347个家庭户,调查到630名适龄儿童,家庭户与适龄儿童数比为34∶1,高于被调查居委会总体的平均水平（14∶1）。14个街道中,各有1个街道建预防接种证率和Hep B第1剂接种率〈90%的标准,10个街道的BCIIMS在管率〈90%的标准。共有37名BCIIMS未在管儿童,其中23名（62.16%）为迁出儿童。调整分析权重和抽样设计后计算接种率,除MCV第2剂外,S-SIA前、后的14个街道适龄儿童总体其他疫苗剂次平均接种率均〉98%。与S-SIA前相比,各疫苗剂次平均接种率的增幅为0.01%-1.55%。结论虽然学龄前流动儿童的BCIIMS在管率有待提高,但针对目标疫苗剂次的S-SIA效果不明显,其策略需调整以提高成本效益。
