营口市1999～2004年常规免疫接种率监测评价

Evaluation on Surveillance Data of Routine Immunization Coverage Rates in Yingkou in 1999-2004

目的了解营口市常规免疫接种率监测现状。方法对1999～2004年常规免疫接种率监测结果，采用差值（D）和比值（R）评价方法进行比较分析。结果县（市、区，下同）级报告的及时率和完整性均为100％，1999～2004年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〉98％，而估计接种率与报告接种率相差较大。除2001、2002年D值不可信外，其余均为可疑或可信。结论常规免疫监测数据存在偏高，主要与流动儿童的免疫规划管理不完善和部分县的工作薄弱有关。应加强技术培训，做好流动人口预防接种管理，提高报告接种率的可信性。

Objective In order to analyze the current status of the routine immunization coverage rates in Yingkou. Methods The surveillance data of routine immunization coverage rates reported from 1999 to 2004 were analyzed using the evaluation method of difference （D） and ratio （R）. Results The results indicated that both the timeliness and completeness of coverage rates reported from 1999 to 2004 were 100%. The routine coverage rates of OPV, DPT, MV, HepB reported during 1999 - 2004 were 98 %, but the estimated coverage rates of these four vaccines ranged from 66.6 % to 117.8%. There are significante differences between reported coverage rates and estimated ones. The evaluation of the different values between reported rates and estimated ones indicated that the data were doubtful or reliable except that the ones in 2001 and 2002 were unbelievable. Conclusions The results suggested that the surveillance data of routine immunization were overestimated, and that the development of EPI in Yingkou was unbalanced due to lack of management of EPI among migrant children and performance of EPI in some areas. We should strengthen technical training and improve immunization management for floating population to enhance the reliability of reported immunization rate.
