为了解安徽省儿童常规免疫接种率报告质量 ,并对现行的监测系统进行评价 ,应用EPIinfo 6 0 4软件对全省 1998年常规免疫接种率报告监测系统提供的数据进行统计分析。结果显示 ,全省常规免疫接种卡介苗、口服脊髓灰质炎疫苗、百白破混合制剂、麻疹疫苗、乙型肝炎疫苗等 5种疫苗的报告接种率均在 90 %以上 ,其估计接种率为 13 7%～ 85 1% ;地区级报告及时率为83 5 % ;对 12个地区的乡级报告数据分析 ,未报 1 8% ;农村和城市报告次数 <5次的分别占 5 1 0 %和 14 4%。通过D值、R值综合评价 ,4个 ( 2 5 % )地区判定为可信 ,其余为不可信 ,因此提高乡级报告工作质量 ,是常规免疫接种率监测系统数据可信性的关键 To understand the quality of routine immunization coverage of children in Anhui Province and to evaluate the current monitoring system, EPIinfo software was used to perform statistical analysis on the data provided by the monitoring system of routine immunization coverage in 1998 in the province. The results showed that inoculation rates of the five kinds of vaccines including routine immunization BCG vaccine, oral polio vaccine, baibaban mixture, measles vaccine and hepatitis B vaccine were over 90% in the province, and the estimated vaccination rate was 13 7 % ~ 85 1%; the reporting rate at the district level was 83.5%; the data of township level reporting in 12 districts were not reported as 18%; the reports of rural and urban areas <5 times accounted for 51.0% and 14 respectively 4%. Through the comprehensive evaluation of D value and R value, 4 (25%) areas are judged as credible and the rest as untrustworthy, so improving the quality of township reporting is the key to the credibility of routine vaccination rate monitoring system data
