目的分析铜川市2011-2016年乙型肝炎（乙肝）报告及其准确性，为改善乙肝监测质量提供依据。方法通过传染病报告信息管理系统收集铜川市所辖4个区县的乙肝病例报告个案并进行个案查重，分析乙肝报告发病率和重复报告率。结果2011-2016年铜川市共报告乙肝病例5148例，其中实验室和临床诊断病例5114例（99．34％），报告发病率为101．29／10万。在实验室和临床诊断乙肝病例中，急性、慢性、未分类乙肝分别占8．41％、80．76％、10．83％；总重复报告率为11．07％（566／5114），各级医疗机构的重复报告率为9．40％-11．49％（X^2=0．81，P〉0．05）。结论铜川市乙肝报告发病率准确性差，各级医疗机构普遍存在乙肝重复报告。

Objective To analyze reporting accuracy for hepatitis B reporting in Tongchuan city during 2011-2016, and to provide evidence for improving hepatitis B surveillance. Methods We used the Na- tional Infectious Diseases Reporting System to collect hepatitis B case reports from 4 counties of Tong- chuan for analysis of reporting incidence and the repetitive reporting rate for hepatitis B. Results A total of 5 148 hepatitis B cases were reported in Tongchuan during 2011-2016, among which 5 114 （99.34%） were laboratory- or clinical-confirmed cases, for a reported incidence of 101.29 per 100 000 population. In laboratory- and clinical-confirmed cases, acute, chronic and unclassified hepatitis B ac- counted for 8.41%, 80.76% and 10. 83%, respectively. The repetitive reporting rate was 11.07% （566/5 114）, ranging from 9.40% to 11.49% （X^2 =0.81, P 〉0.05） by hospital level. Conclusions The accuracy of reported incidence of hepatitis B was low in Tongchuan, with repeat reports being corn- mon in all hospital levels
