目的 了解2018—2023年安徽省丙型病毒性肝炎(丙肝)病例重复报告现况及影响因素,为提高丙肝报告质量提供参考依据。方法 在中国疾病预防控制信息系统丙肝防治信息系统下载录入日期为2018年1月1日至2023年12月31日、现住址为安徽省的全部丙肝个案,依据患者身份证号进行查重,使用SPSS 23.0软件进行统计分析。结果 2018—2023年安徽省报告的62 588丙肝例中,重复报告13 693例,重复报告率为21.88%,且呈现逐年上升趋势(χ²_趋势=1 848.536,P<0.001)。重复报告以跨年度重复为主,占重复报告的59.66%。logistic回归分析结果显示,年龄在30岁以上(31~60岁:OR=1.517,95%CI:1.370~1.681,P<0.001;≥61岁:OR=1.704,95%CI:1.533~1.895,P<0.001)、家务及待业人群(OR=1.226,,95%CI:1.162~1.294,P<0.001)、离退休人群(OR=1.294,95%CI:1.209~1.384,P<0.001)、报告病例类型为确诊病例(OR=1.077,95%CI:1.022~1.134,P=0.005)、诊断状态为慢性(OR=2.126,95%CI:1.714~2.637,P<0.001)和未分型(OR=3.263,95%CI:2.618~4.068,P<0.001)丙肝重复报告率较高。相对于男性,女性丙肝重复报告率较低(OR=0.922,95%CI:0.888~0.959,P<0.001)。结论 安徽省2018—2023年丙肝重复报告率较高,呈现逐年上升的趋势,重复报告以跨年度重复为主。病例反复就诊和报卡时重卡识别功能有限是造成重复报告的两大原因。建议加强丙肝网络报告时的重卡识别功能,结合重复报告病例特征采取有针对性的措施,有望减少丙肝重复报告现象。

Objective To understand the current status and factors affecting repeat reporting of hepatitis C in Anhui Province from 2018 to 2023,and to provide reference for improving the quality of hepatitis C reporting. Methods Data on all hepatitis C cases with entry dates from January 1, 2018 to December 31, 2023 and current address in Anhui Province were downloaded from the Hepatitis C Prevention and Control Information System of China Disease Prevention and Control Information System.The repeat reports were checked based on the patients’ ID number.Statistical analysis was performed by using SPSS 23.0 software. Results Of the 62 588 hepatitis C cases reported in Anhui Province from 2018 to 2023,13 693 cases were repeated report,with a repeat reporting rate of 21.88%.Repeat reporting rate showed an upward trend from year to year (χ${}_{trend}^{2}$=1 848.536,P<0.001).Repeat reports were predominantly repeated across years,accounting for 59.66% of the repeated reports.The results of logistic regression analysis showed that people over 30 years old (31-60 years:OR=1.517,95% CI:1.370-1.681,P<0.001;≥61 years:OR=1.704,95% CI:1.533-1.895,P<0.001),the household and inactive population (OR=1.226,95% CI:1.162-1.294,P< 0.001),retired population (OR=1.294,95% CI:1.209-1.384,P<0.001),reported case type as confirmed cases (OR=1.077,95% CI:1.022-1.134,P=0.005),diagnosis status as chronic (OR=2.126,95% CI:1.714-2.637,P<0.001) and untyped cases (OR=3.263,95% CI:2.618-4.068,P< 0.001) were correlated with high rate of repeat reporting of hepatitis C.Compared to males,females had a lower rate of repeat reporting of hepatitis C (OR=0.922,95% CI:0.888-0.959,P<0.001). Conclusion The repeat reporting rate of hepatitis C in Anhui Province is high from 2018 to 2023,and shows an increasing trend year by year.Repeat reports are mainly repeated across years.Repeated visits by cases and limited functionality in recognizing repeat cards at the time of card reporting are the two main reasons for repeat reporting.It is recommended to enhance the ability of identification of repeat cards when reporting on the hepatitis C network.Targeted measures that incorporate the characteristics of repeat cases are expected to reduce repeat reporting of hepatitis C.
