目的 了解芜湖市丙型病毒性肝炎病例的重复报告情况,分析影响重复报告的因素。方法 收集中国疾病预防控制信息系统中的传染病监测系统芜湖市2017—2021年丙型病毒性肝炎病例,根据患者身份证号或患者姓名、性别、人群分类、疾病名称、出生日期、现住址核对报告病例是否重复报告,计算丙型病毒性肝炎病例重复报告率。结果 2017—2021年医疗机构共报告丙型病毒性肝炎5 317例,重复报告928例,重复报告率为17.45 %。其中年度内重复报告240例,年平均重复报告率为4.5％,不同年度重复报告差异无统计学意义(χ²＝1.036,P＞0.05);年度间重复报告688例,重复报告率为13.55％。患者年龄越大,重复报告率越高,不同年龄人群重复报告率差异有统计学意义(χ²＝68.89,P＜0.05);重复报告率从高到低依次为地市级(19.14%)、省级(17.69%)、乡镇及以下(16.56%)、县区级(15.21%)。结论 芜湖市丙型病毒性肝炎病例报告存在重复报告情况,以省市医疗机构重复报告、跨年度重报为主。

Objective To understand the repeated reporting of hepatitis C in Wuhu City and analyze the factors affecting the repeated reporting. Methods The reported cases of hepatitis C in Wuhu City from 2017 to 2021 were collected from the infectious disease surveillance system of the China Disease Prevention and Control Information System.The repeat reporting rate of hepatitis C cases was calculated by checking whether the reported cases were repeatedly reported according to the patient's ID number or patient's name,gender,population classification,disease name,date of birth,and current address. Results A total of 5 317 cases of hepatitis C were reported by healthcare institutions from 2017 to 2021,and 928 cases were repeatedly reported,with a repeat reporting rate of 17.45 %.A total of 240 cases were repeatedly reported in the year,with an average annual rate of 4.5%.There was no significant difference in the repetition rate between years (χ²=1.036,P>0.05).688 cases were repeatedly reported between years,with a repeat reporting rate of 13.55%.With the increase of age,the repeat reporting rate showed an upward trend.There was a statistically significant difference in the repeat reporting rate among the different age groups (χ²=68.89,P<0.05).The repeat reporting rate,in descending order,was at the prefectural and municipal levels (19.14%),provincial level (17.69%),township and below (16.56%),and county and district levels (15.21%). Conclusion There is repeated reporting of Wuhu City hepatitis C cases,mainly in the form of repeated reporting by provincial and municipal medical institutions and re-reporting across years.
