芜湖市2017—2021年丙型病毒性肝炎病例重复报告现况分析

Analysis of the current status of repeated reporting on hepatitis C cases in Wuhu City from 2017-2021

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(χ^(2)=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(χ^(2)=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(χ^(2) = 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(χ^(2) = 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.
