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。
Objective To explore the feasibility of directly evaluating the vaccination rate of children through vaccination information system. Methods The vaccination coverage of the National Immunization Program (EPI) was expanded in the survey counties through the Children Immunization Information Management System (CIIMS), and compared with the results of surveys on the Probability Proportional to Size (PPS) And routine immunization coverage rates were compared. Results A total of CIIMS totaled 3 264 children aged 1 and 3 205 children aged 2 years in the surveyed counties. The PPS conducted a total of 420 children in the household survey, of which 210 were 1-year-old and 2-year-old. Inoculation rate of routine immunization survey in 2010 was> 99.00% for each dose of vaccine. Inoculation rates obtained by CIIMS and PPS by χ2 test, 1 year old Hepatitis B Vaccine (HepB) 2, Diphtheria, Pertussis and Tetanus Combined Vaccine (DPT )) There was significant difference in the inoculation rate between the first dose and the first dose of Measles-containing Vaccine (MCV) (P <0.05); the third dose of HepB, the third dose of DTP, the third dose of MCV (P <0.05). There was no significant difference in the other vaccines and inoculation rates (P> 0.05). The differences of vaccination rates between the two vaccines and Japanese Encephalitis Vaccine (JEV) were statistically significant (P < > 0.05). 1 year old and 2 year old CIIMS statistical inoculation rate and 2010 routine immunization monitoring report inoculation rate by χ2 test, respectively 7 doses and 13 doses vaccination rate difference was statistically significant (P <0.05), accounting for 58.33% And 72.22%. Conclusion The rapid and accurate inoculation rate through CIIMS is a powerful tool to evaluate immunization planning.
