ABSTRACT
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.
