【摘要】 目的探索通过预防接种信息系统直接评价儿童接种率的可行性。方法在调查县通过儿童预防接种信息管理系统(Children Immunization Information Management System,CIIMS)统计其扩大国家免疫规划疫苗接种率,并与按容量比例概率抽样法(Probability Proportional to Size,PPS)接种率调查结果和常规免疫报告接种率进行对比分析。结果 CIIMS共统计到调查县1岁儿童3 264人,2岁儿童3 205人。PPS法共入户调查420名儿童,其中1岁和2岁各210人。2010年调查县常规免疫报告接种率各疫苗各剂次均>99.00%。CIIMS和PPS两种方法得到的接种率经χ2检验,1岁儿童乙型肝炎疫苗(Hepatitis B Vaccine,HepB)第2剂、百日咳-白喉-破伤风联合疫苗(Diphtheria,Pertussis and Tetanus Combined Vaccine,DPT))第1剂和含麻疹成分疫苗(Measles-containing Vaccine,MCV)第1剂接种率的差异有统计学意义(P<0.05);2岁儿童HepB第3剂、DTP第3剂、MCV第2剂、乙脑疫苗(Japanese Encephalitis Vaccine,JEV)第1剂和第2剂接种率的差异有统计学意义(P<0.05),其余疫苗及剂次接种率的差异均无统计学意义(P>0.05)。1岁和2岁CIIMS统计接种率和2010年常规免疫监测报告接种率经χ2检验,分别有7剂次和13剂次的疫苗接种率的差异有统计学意义(P<0.05),占58.33%和72.22%。结论通过CIIMS统计接种率迅速、准确,是评价免疫规划工作的有力工具。更多还原

【Abstract】 Objective To explore the feasibility of immunization coverage for the county by using Children Immunization Information Management System(CIIMS).Methods In the survey county,the coverage of the national expanded program on immunization(NEPI) was collected by CIIMS,comparing with the probability proportional to size(PPS)survey.Results By CIIMS,3 264 targeted children(1-year-old) and 3 205 targeted children(2-year-old) were observed.Using PPS,420 children were surveyed,including 210 targeted children of 1-year-old and 2-year-old.Two methods tested by chi-square showed that in one-year age group,the vaccine coverage had significant difference(P <0.05)on the second dose of HepB(hepatitis B vaccine),the first dose of DPT(diphtheria,pertussis and tetanus combined vaccine),the first dose of MCV(measles-containing vaccine);in two-year age group,the vaccine coverage had significant difference(P < 0.05)on the third dose of HepB,the third dose of DPT,the second dose of MCV,the first and the second dose of Japanese encephalitis vaccine.There was no statistical difference in the rest of the vaccine.Conclusion Estimating vaccination rates by CIIMS is quick and accurate,it could be used to evaluate immunization program.更多还原
