Objective To review the diagnostic information of 3368 viral hepatitis B inpatient cases reported by some healthcare institutions in Qinghai Province in the National Notifiable Disease Report System(NNDRS)in 2021,and to analyse the consistency of their reports and influence factor.Methods The study used the typical survey method to study 3368 hospitalized cases of hepatitis B reported by 32 medical institutions in Qinghai Province in 2021 from July 2022 to April 2023.The consistency between the reported classification and the reviewed classification was evaluated by reviewing diagnostic information of the cases,combined with the Kappa consistency test,and the consistency-influencing factors were analysed in a univariate and multivariate analysis.Results The consistency between acute,chronic,and unclassified reporting classifications and review classifications was poor(Kappa＜0.40);the consistency between acute and chronic review was poor(Kappa＜0.40).The main influence factor of the consistency of review included the level of medical institution,the patient's gender,occupation,past history,and the unit of diagnosis of initial onset of illness.Provincial medical institutions reported higher consistency,and male cases and herder cases had better consistency than female cases and other occupations.Review consistency of cases with past history was better than that of cases with unclear past history.Conclusion The consistency of diagnosis and reporting of hepatitis B cases in healthcare institutions in Qinghai Province in 2021 was low,with problems of inaccurate classification and duplicate reporting.It is recommended to strengthen the training and supervision of healthcare institutions,standardise the filling of'attached card'information,and promote the hepatitis B core antibody IgM test to improve the classification and diagnosis of acute and chronic hepatitis B,so as to comprehensively improve the accuracy of the diagnosis and reporting of hepatitis B cases.

OBJECTIVETo investigate the predictive value of hepatic venous pressure gradient (HVPG) for early bleeding after esophageal variceal ligation (EVL) by analyzing the differences in HVPG in patients with and without post-EVL bleeding.

METHODSThe medical records of patients who had been diagnosed with cirrhosis and esophageal varices and who had pre-EVL HVPG measurement data were surveyed. The study population included 105 patients from October 2010 to March 2014. Data of HVPG value, previous treatment history, endoscopic manifestation, and whether bleeding and serious complications occurred within 2 weeks after the ligation procedure were investigated as independent risk factors.

STATISTICAL METHODSincluded the chi-square test and Wilcoxon test, logistic regression modeling and receiver operating characteristic (ROC) analysis using the SPSS software version 16.

RESULTSOnly HVPG value was identified as an independent risk factor of early bleeding after EVL.According to the ROC analysis, the area under the curve (AUC) of HVPG for early bleeding after EVL was 0.866; when HVPG was more than or equal to 16 mmHg, AUC was 0.838. The sensitivity was 90.9% and the specificity was 76.4%.

CONCLUSIONHVPG is an independent factor of early bleeding after EVL and when HVPG cut-off value of more than or equal to 16 mmHg is used the predictive ability has certain accuracy and high sensitivity and specificity.
