Analysis on cases reporting and serological test results of hepatitis B in hospitals at different levels in Baoshan, Yunnan

Objective To analyze the case reporting and serological test results of hepatitis B in hospitals at different levels in Baoshan, Yunnan province, and explore the possible problems in the case reporting.

Methods The data of hepatitis B cases reported in Baoshan in 2016 were downloaded from China disease prevention and control information system, including cases reported in other areas but now living in Baoshan. The data included demographic data, case reporting data, and serological test results, such as alanine aminotransferase (ALT), hepatitis B core antibody-IgM (HBcAb-IgM). Database was established by Excel, and software SPSS 19.0 was used for data process and analysis.

Results The number of cases of HBsAg carriers, unclassified, abnormal ALT, ALT＞P₇₅, and undetected HBcAb-IgM reported by class I hospitals and class II hospitals were higher than those reported by hospitals at other level, the differences were statistically significant (χ²＝884.623, 885.244, 489.321, 560.361, 1 124.17, respectively, P＜0.01). Similarly, for each of the above indicators, the number of cases reported by health center and general hospitals was higher than that reported by other type hospitals, the difference was statistically significant (χ²＝316.875, 309.754, 359.044, 473.882, 332.055, respectively, P＜0.01).

Conclusion More cases of hepatitis B were reported by class II hospitals and class I hospitals, but more cases were misreported. It is necessary to strengthen the case verification in county-level general hospitals and health centers.
