目的通过设立乙型病毒性肝炎监测点,了解法定报告系统中急、慢性乙肝的构成,提高乙肝分类诊断的准确性。方法收集监测点2013年-2014年报告的乙肝病例核心信息,对报告的乙肝病例开展相应的实验室检测。结果2013年-2014年云浮市监测点共报告1 178例乙肝,男、女性别比为2.78∶1,平均年龄为43.6岁,集中在20岁~65岁,职业以农民、工人和待业为主。监测点乙肝急性、慢性和未分类病例分别占4.07%、95.76%和0.17%,而非监测点中乙肝急性、慢性和未分类病例分别占4.66%、68.92%和26.42%。监测点6项核心信息填写率,除“首次出现症状时间”一项外,其余均比非监测点填写率高。结论监测点报告的乙肝病例以慢性病例居多,未分类病例比例大幅下降,乙肝急、慢性分类准确性高于非监测点,开展实验室诊断对提高乙肝病例分类准确性非常必要。
OBJECTIVE To understand the constitution of acute and chronic hepatitis B in the statutory reporting system by establishing a monitoring point of hepatitis B virus and improve the accuracy of the diagnosis of hepatitis B classification. Methods Collect the core information of hepatitis B cases reported by the monitoring points from 2013 to 2014 and carry out the corresponding laboratory tests on the reported hepatitis B cases. Results From 2013 to 2014, a total of 1,178 hepatitis B patients were tested in Yunfu City, with a ratio of 2.78:1. The average age was 43.6 years, with a concentration of 20 years to 65 years. Occupations were mainly farmers, workers and unemployed . The acute, chronic and unclassified cases of hepatitis B in surveillance sites accounted for 4.07%, 95.76% and 0.17% respectively, while the acute, chronic and unclassified cases of hepatitis B in non-surveillance sites accounted for 4.66%, 68.92% and 26.42% respectively. Monitoring points 6 core information fill rate, except for “first symptom onset ” one, the rest are higher than non-monitoring point fill rate. Conclusion The reported cases of hepatitis B in the monitoring sites are mostly chronic cases, the proportion of unclassified cases dropped significantly, and the diagnostic accuracy of chronic hepatitis B and chronic diseases was higher than that of non-monitoring points. It is necessary to carry out laboratory diagnosis to improve the classification accuracy of hepatitis B cases.
