摘要
目的探索一种适合以县为单位应用的计算机辅助电话调查(Computer-assisted Telephone Interviewing,CATI)和非入户儿童接种率调查评价方法 。方法 在调查县应用CATI移动电话抽样技术,随机确定1岁、2岁各100名儿童作为目标儿童,通过儿童预防接种信息管理系统(Children Immunization Information Management System,CIIMS)获得目标儿童的预防接种信息,评价其扩大国家免疫规划疫苗的接种率,并与按容量比例概率抽样法(Probability Proportional to Size,PPS)接种率调查结果进行对比分析。结果 CATI调查共拨打移动电话号码8040个,获得1岁、2岁目标儿童样本215人,其中206名目标儿童通过嘉鱼县CIIMS或在预防接种单位获得了预防接种信息。PPS法共入户调查420名儿童,其中1岁和2岁各210人。两种方法 的调查接种率经卡方检验,1岁儿童口服脊髓灰质炎减毒活疫苗(Oral Poliomyelitis Attenuated Live Vaccine,OPV)第3剂、"四种疫苗"[卡介苗、OPV、白喉-破伤风-百日咳联合疫苗(Diphtherid,Tetanus and Pertussis Combined Vaccine,DTP)、含麻疹成分疫苗(Measles-containing Vaccine,MCV)]接种率、"五种疫苗"(以上的四种疫苗+乙型肝炎疫苗)全程免疫接种率,2岁儿童DTP第4剂、MCV第2剂、A群脑膜炎球菌多糖疫苗第1剂和第2剂的接种率,以及甲型肝炎疫苗的接种率的差异均有统计学意义(P<0.05),其余疫苗接种率的差异均无统计学意义。结论 CATI移动电话抽样和非入户接种率调查方法 简单、实用,可试用于以县为单位儿童预防接种率调查。
Objective To explore the evaluation method of vaccine coverage for county by using computer-assisted telephone interviewing(CATI) and not household survey. Methods By CATI, we determine the 100 targeted children who are l-year-old, 2-year-old, then through the child immunization information management system, we collect the targeted children vaccines information of the national expanded program on immunization (NEPI) and get the information of coverage, with comparing the probability proportional to size (PPS) survey. Results We called 8040 cell phone numbers and got 215 targeted samples, 206 targeted children founded by CIIMS. The PPS survey got 420 samples. Two methods by chi-square test showed that in one-year age group, the vaccine coverage had significant difference (P 〈0.05 ) on group A meningococcal polysaccharide vaccine, the third dose of oral poliomyelitisl attenuated live vaccine, four and five vaccines; in two-year age group, (P〈0.05) on the forth dose of diphtheria, tetanus and the vaccine coverage had significant difference pertussis combined vaccine, the second dose of measles containing vaccine, the second dose of Japanese encephalitis vaccine and hepatitis A vaccine. There was no statistical difference in the rest of the vaccine. Conclusions The CATI mobile phone sampling and not face to face vaccine coverage survey method can be used to the children vaccine coverage survey at county-level.
