摘要
目的分析哈尔滨市2011年疑似预防接种异常反应(Adverse event following immunization,AEFI)的特征,评价AEFI监测系统运转情况。方法对《疑似预防接种异常反应信息管理系统》报告的哈尔滨市2011年AEFI数据进行描述性分析。结果 2011年哈尔滨市共报告188例AEFI,以一般反应为主,占报告总数的86.7%;下半年报告的病例占全年总数的72.9%;年龄≤1岁和1岁<年龄≤2岁组报告病例最多,分别占总数的42.0%和36.2%;吸附无细胞百白破联合疫苗因接种针次多,AEFI发生数也最多,占总数的49.5%;一般反应中,报告最多的是发热、红肿、硬结,占85.1%。结论哈尔滨市AEFI及时报告率、及时调查率、调查表及时上报率等监测指标均达到较高水平。今后应加强对基层人员的培训和督导检查,在乡级单位开展网络直报,进一步提高AEFI监测系统的敏感性和及时性。
