Abstract: Objective To explore a comprehensive management mode to increase classification ratio of acute hepatitis cases.Methods To analyze the cause of low classification ratio of acute viral hepatitis reported by hospitals in Zhabei District in 2008-2009, then propose, practice and evaluate the management mode in 2010.Results Lack of tracing unclassified cases was found to be the main cause of low classification ratio. An omni tracing mode for hepatitis classification was introduced and found to be very effective to increase tracing ratio of unclassified cases and furthermore increase classification ratio. The tracing ratio and classification ratio reached 90.38% and 93.06% in 2010 which were significantly higher than the two of 72.38% (χ²=13.61,P=0.00)and 69.44% (χ²=28.92,P=0.00) in 2008, also the two of 80.14% (χ²=4.84,P=0.03)and 80.92%(χ²=9.52,P=0.00) in 2009.Conclusion The omni tracing mode is effective and practical to increase classification ratio.
