Abstract:
Objective To evaluate the quality of the hepatitis B report data on a pilot surveillance in Zhejiang Province from 2013 to 2015.Methods Hepatitis B report data of 6 pilots in Zhejiang Province from 2013 to 2015 were extracted from national notifiable infectious disease reporting system,including reported cases of hepatitis B,classification of hepatitis B cases and supplementary card information etc. To evaluate the accuracy of hepatitis B classification,information of supplementary cards was used to make classification diagnose for hepatitis B.Results A total of 3214 hepatitis B cases were reported in 6 pilot surveillance counties in Zhejiang Province between 2013 and 2015. Excluded 32 duplicated cases within the year and between years,3182 hepatitis B cases were actually reported,hepatitis B cases repeated reporting rate was 1%. A total of 2717 hepatitis B cases were correctly classified,and the accuracy rate of classification was 85.39%,showing an increasing trend (P<0.05). The proportion of accurate classification of reported hepatitis B by referring to the results of positive time of HBsAg and ALT from the supplementary card were 80.86% and 97.29% respectively. Among those reported acute hepatitis B cases,90.43% of them filled with anti-HBc IgM positive in supplementary card. The proportion of accurate classification of reported hepatitis B by referring to the information for liver puncture and the HBsAg and anti-HBs transform during the recovery period in supplementary cards were 0.19% and 5.13% respectively. Among those reported acute hepatitis B cases,0.69% of them were chronic or undetermined. Among those reported chronic hepatitis B cases,13.92% of them were acute,undetermined or HPV carrier. Five out of 3182 cases were unclassified,accounting for 0.16%.Conclusion The quality of classification diagnosis for hepatitis B should be improved in Zhejiang Province. Filling in the supplementary card is very beneficial for the classification of hepatitis B.
