嵊州市2003～2005年常规免疫接种率监测评价

Evaluation on Surveillance Date of Routine Immunization Coverage in Shengzhou in 2003～2005

目的为了解嵊州市常规免疫接种率监测系统的现状。方法采用差值(D值)和比值(R值)评价方法对2003～2005年的监测资料进行比较分析。结果2003～2005年卡介苗、口服脊髓灰质炎疫苗、百白破联合疫苗、麻疹疫苗、乙型肝炎疫苗的常规免疫报告接种率均>99%,而估算接种率在75.57%～95.12%之间,与报告接种率相差较大。D值显示2003和2004年D值不可信,2005年可疑。R值显示2003和2005年报告资料可疑,2004年报告资料不可信。结论常规免疫监测数据存在偏高现象,主要与乡镇免疫工作人员业务素质较低,流动儿童的免疫规划管理不完善有关。应加强对免疫接种的监督管理和技术培训,完善流动儿童免疫接种管理。

objective In order to analyze the current status of the routine immunization coverage rates in Shenghzou. Methods The surveillance data of routine immunization coverage rates reported from 2003 to 2005 were analyzed using the evaluation method of difference （D） and ratio（R）. Results The routine coverage rates of BCG, OPV, DPT MV, HBV reported during 2003-2005 were 99%, but the estimated coverage rates of these five vaccines ranged from 75.57% to 95.12%. There are significant differences between reported coverage rates and estimated ones. By evaluating of the different values of reported and estimated rates, indicated that the data in 2003 and 2004 were unbelievable, the ones in 2005 were doubtful. Conclusion The results suggested that the surveillance data of routine immunization were overestimated. The main reason may be associated with the service quality of township immunity doctor is lower and the missed EPI administration for floating children. We should strengthen surveillance and technical training for EPI, improve immunization management for floating children.
