目的应用儿童预防接种信息管理系统(Children Immunization Information Management System,CIIMS)平台对接种率进行分析和评价。方法对CIIMS数据质量、CIIMS平台统计扩大国家免疫规划(National Immunization Program,NIP)疫苗接种率、按容量比例概率抽样法(Probability Proportional to Size,PPS)调查接种率进行分析。结果 CIIMS单位实施率、数据及时上传、备份率达到100%;儿童个案信息录入率逐年提高,2013年个案上传率达到98.91%,个案重复率在0.19%~1.28%,及时录入率和信息准确率达到95%的接种单位分别占72.24%和93.06%。2010年、2011年、2012年出生儿童11剂次疫苗的接种率CIIMS和PPS法均在90%以上,多数剂次疫苗接种率在两种方法之间有显著性差异(χ~2检验,P<0.05),其中满1岁接种的疫苗剂次CIIMS统计的接种率均略低于PPS法。结论 CIIMS数据获取方便、结果准确,可用于评价疫苗接种率,但需定期进行数据维护,CIIMS目前尚不能取代接种率调查。
Objective To analyze and evaluate the vaccination rate by using the platform of Children Immunization Information Management System (CIIMS). Methods The CIIMS data quality and the CIIMS platform were used to expand the national immunization program (NIP) vaccination rate and analyze the vaccination rate according to the Probability Proportional to Size (PPS) survey. Results The implementation rate and data of CIIMS units were up-to-date with the backup rate of 100%. The case-based information entry rate of children increased year by year. The case upload rate reached 98.91% in 2013 and the case repetition rate was 0.19% ~ 1.28% 95% of the vaccination units accounted for 72.24% and 93.06% respectively. In 2010, 2011 and 2012, the immunization rates of 11 doses of vaccination for children born in 2012 were over 90% in both CIIMS and PPS methods, and the most of the vaccination rates in most of the doses were significantly different between the two methods (χ ~ 2 test, P <0.05), among which the vaccination rate of vaccines over the age of one year was slightly lower than that of the PPS method. Conclusion The CIIMS data are easy to obtain and accurate. It can be used to evaluate the vaccination rate. However, CIIMS data can not be substituted for the inoculation rate yet.
