目的评价山东省预防接种信息系统(Immunization Information System,IIS)1~7岁儿童免疫规划疫苗接种率,为该系统在接种率监测中的应用提供参考依据。方法对山东省IIS收集的1~7岁儿童接种个案分年龄组、分地区、分户籍类型进行疫苗接种率分析。结果山东省IIS共收集1~7岁儿童个案8 049 733例;12月龄、24月龄、5岁和7岁应种疫苗接种率分别为93.35%~98.39%、88.47%~91.37%、75.08%~84.13%、52.87%~62.73%;莱芜、临沂、聊城、菏泽等市接种率处于全省较低水平;流动儿童接种率明显低于常住儿童。结论山东省免疫规划工作呈逐年加强趋势;24月龄以上年龄组、鲁西南和流动儿童是预防接种管理重点;在加强数据质量控制前提下,可利用IIS进行接种率监测与评价。
Objective To evaluate the vaccination rate of Immunization Information System (IIS) immunization programs for children aged 1 ~ 7 years in Shandong Province and provide a reference for the application of this system in the surveillance of inoculation rates. Methods The vaccination rate of 1 to 7 years old children collected from IIS in Shandong Province was analyzed by age group, sub-region and household type. Results A total of 8 049 733 cases of children aged 1 to 7 years were collected in IIS of Shandong Province. The vaccination rates of 12 months, 24 months, 5 years and 7 years old were 93.35% -98.39%, 88.47% -91.37%, 75.08 % -84.13%, 52.87% -62.73%. The immunization rates in Laiwu, Linyi, Liaocheng and Heze cities were lower in the province. The vaccination rate of migrant children was significantly lower than that of the resident children. Conclusion The immunization planning in Shandong Province has been strengthened year by year. The age group of over 24 months, the southwest of Shandong Province and migrant children are the key points of vaccination management. Under the premise of improving data quality control, IIS can be used to monitor and evaluate the vaccination rate.
