[Data analysis on hepatitis B through pilot surveillance reporting system in Henan province, 2012-2016]

Area of Science:

• Hepatology and Virology
• Public Health Surveillance
• Epidemiology

Background:

• Hepatitis B (HB) reporting systems require standardization to enhance monitoring quality.
• Previous reporting systems in Henan province faced challenges in data accuracy and classification.
• Improving surveillance is crucial for effective public health interventions against Hepatitis B virus (HBV).

Purpose of the Study:

• To standardize the reporting system for hepatitis B in Henan province.
• To improve the overall quality of the hepatitis B monitoring program.
• To assess the impact of a pilot surveillance program on reporting accuracy and diagnosis.

Main Methods:

• A pilot surveillance program was implemented across six sites in Henan province from 2012 to 2016.
• Data on hepatitis B case classification, HBsAg positivity, and ALT levels were analyzed annually.
• Anti-HBc IgM testing was performed on suspected acute hepatitis B cases to confirm diagnosis.

Main Results:

• Reported hepatitis B cases decreased by 84.90% between 2011 and 2016 in the monitored sites.
• The proportion of unclassified hepatitis B cases dropped from 36.87% to 0.08%, indicating improved classification.
• The rate of misdiagnosis for HBV carriers significantly decreased, and ALT detection rates improved.

Conclusions:

• The pilot surveillance program successfully improved the quality of hepatitis B reporting and diagnostic accuracy.
• Standardization of reporting and enhanced testing methods are vital for effective hepatitis B surveillance.
• Continued efforts are needed to further refine reporting accuracy and testing methodologies at monitoring sites.
