2006-2007年四川省监测点乙型病毒性肝炎病例报告情况分析

Analysis of Hepatitis B Morbidity at Sentinel Surveillance Sites of Sichuan Province in 2006-2007

目的分析四川省监测点乙型病毒性肝炎(乙肝)发病报告的准确性,为规范乙肝报告提供依据。方法根据四川省乙肝监测试点县(区)所有医疗机构网络直报乙肝病例以及对报告病例中符合监测对象病例进行流行病学个案调查并采集血清标本进行实验室检测后复核诊断,统计急、慢性乙肝病例构成。结果监测点医疗机构通过"疾病监测信息报告管理系统"报告的乙肝病例中未分类病例所占比例较高(43.67%);缺乏实验室诊断依据的病例占17.70%;医院和省级实验室检测HBsAg、抗HBcIgM一致率分别为96.23%、56.18%;急性乙肝误诊率80.49%。结论目前的乙肝报告难以真实反映四川省急性和慢性乙肝的发病现状,进一步健全乙肝的监测和报告系统是必要的。

Objective To analyze the accuracy of HBV morbidity report and provide the basis for the standardized HBV surveillance. Methods We collected the cases of hepatitis B （HBV） from two pilot sentinel surveillance sites in Sichuan province and processed the investigation, took and re-tested blood sample, then calculated the proportion of the acute hepatitis B and the chronic hepatitis B. Results In the cases reported by the hospitals from NNDRS （national notifiable disease report system）, the proporti6n of cases without classification was 43.67%, the proportion of cases without experimental result was 17. 70%, the consistency of the HBsAg, HBcIgM between the results of provincial CDC and the results of hospitals was 96. 23% and 56. 18% respectively, the proportion of acute Hepatitis B misdiagnosises was 80. 49%. Conclusions According to the present HBV morbidity reports, we cannot get the accurate and reliable information about the disease incidence and current situation of acute hepatitis B and chronic hepatitis B. It＇s necessary to enhance the surveillance of hepatitis B in Sichuan province.
