Analysis on the quality of reporting date of hepatitis C in Urumqi, 2016

Objective Through investigation of the special subject, we hope to understand the diagnostic reports on viral hepatitis C (hepatitis C) in Urumqi in 2016 as well as the inconsistencies between report of acute and chronic hepatitis C cases and the diagnosis of clinicians and other questions, and thus promote the standardization of diagnosis and reporting of hepatitis C. Methods We adopted stratified random sampling method, sampling the directly reported hepatitis C cases from the network of 37 medical units in Urumqi in the first quarter of 2016. By accessing the hospital information system (HIS) according to hospitalization number, we obtained the subjects’ visit information and record of diagnosis on discharge, among which we further verified the data quality of hepatitis C - related cases in the first quarter of 2016. Results Among the total sampling of 12 diagnosis and treatment institutions at provincial/municipal/county level with 333 cases of factual investigation, only 50.0% (6/12) were capable of nucleic acid test (NAT). In the judgment of diagnosis and classification, the accuracy for clinically diagnosed cases was 67.8% (120/177), 58.3% (91/156) for laboratory confirmed cases (x2=3.20, P=0.070); 84.9% (107/126) for the diagnosis and classification of hepatitis C disease department, and 57.1% (72/126) for the classification between acute and chronic, which were all higher than those of the non-hepatology departments as 50.2% (104/207) and 48.3% (100/207) (x2=40.60, P<0.01; x2=2.40, P=0.110 ). In addition, 2 medical institutions among them misjudged the case as acute hepatitis C, resulting in 0 (0/40) accuracy for the classification of acute and chronic. Conclusions Currently, the hepatitis C NAT capability in medical institutions in Urumqi is relatively weak, and the accuracy for the classification of case reports relatively low. It is suggested that we should strengthen the hepatitis C nucleic acid laboratory capacity of medical institutions in Urumqi and enhance the quality of Hepatitis C diagnosis reports produced by medical staff.
