  Abstract: Abstract Objective: To review the diagnostic information of 3,368 viral hepatitis B (Hepatitis B) inpatient cases reported by some healthcare institutions in Qinghai Province in the National Statutory Infectious Disease Reporting Information Management System in 2021, and to analyse the consistency of their reports and the factors affecting them. Methods: From July 2022 to April 2023, 3368 hepatitis B inpatient cases reported by 32 medical institutions in Qinghai Province were selected for the study using a typical survey method. The consistency between the reported classification and the reviewed classification was evaluated by reviewing the diagnostic information of the cases, combined with the Kappa consistency test, and the consistency-influencing factors were analysed in a univariate and multivariate manner. Results: In 3368 NNDRS-reported hepatitis B inpatient cases, 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 factors affecting the consistency of review included the level of the medical institution, the patients gender, occupation, past history, and the unit of diagnosis of the 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. 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 anti-HBc 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.
