| 目的 分析全国传染病报告信息管理系统（National Notifiable Disease Report System，NNDRS）中2011-2013年乙型肝炎（乙肝）报告病例中的重复报告现状，了解重复报告对乙肝报告发病的影响。方法 在NNDRS中，按照“报告地区浏览”下载“发病日期”在2011年1月1日至2013年12月31日期间所有报告病种为乙肝的个案，剔除“删除个案”后，根据识别个案的5项主要指标（身份证号码、姓名、性别、出生日期、现住址编码）的不同组合，形成6种查重方案，通过SAS 9.1.3软件编程实现重复病例查找。结果 2011-2013年NNDRS报告的3 389 374例乙肝个案中，重复病例249 047例，重报率为7.35%，其中6种查重方案可发现重报率范围为0.88%～6.38%。以2011年个案库为基准，3年重报率分别为2.91%、8.11%和11.72%。重报个案中，年度内重复报告占33.04%（71 709例），跨年重复报告占66.96%（145 329例）。去除重报个案后，2013年新疆维吾尔自治区和青海省乙肝报告发病率可分别下降30.80/10万和26.26/10万。结论 2011-2013年NNDRS报告乙肝病例中约有7.36%的重报，重复报告以跨年重报为主。乙肝重复报告对新疆、青海等省份的发病率统计影响较大。 |

| Objective To analyze the duplicated reporting of hepatitis B in the national notifiable communicable disease report system (NNDRS) in China during 2011-2013. Methods The data of hepatitis B reported from January 1, 2011 to December 31, 2013 were collected from NNDRS, the duplicated reporting were searched with software SAS 9.1.3 according to the cases'ID number, name, gender, birth data and current address code. Results During 2011-2013, a total of 3 389 374 hepatitis B cases were reported through NNDRS, but the duplicated reporting rate was 7.35% (249 047). According to 6 protocols, the duplicated reporting rate ranged from 0.88% to 6.38%. If using the data in 2011 as the baseline, the duplicated reporting rate in the three years was 2.91%, 8.11% and 11.72%, respectively. In the duplicated repeating, 33.04% (71 709) occurred in the same year, and 66.96% (145 329) occurred in other year. Without the duplicated repeating, the hepatitis B incidence in Xinjiang and Qinghai provinces in 2013 could decreased by 30.80/100 000 and 26.26/100 000, respectively. Conclusions The analysis indicated that the duplicated repeating rate of hepatitis B was 7.36% in NNDRS during 2011-2013, and the duplicated reporting mainly occurred in other years. The duplicated reporting of hepatitis B in NNDRS had greatly affected the accuracy of surveillance data in some provinces, such as Xinjiang and Qinghai. |
