湖北省荆州市流感监测哨点监测质量及流感病毒核酸检测阳性率影响因素分析

Sentinel surveillance quality of influenza and influencing factors for influenza virus nucleic acid detection in Jingzhou, Hubei

  • 摘要:
    目的比较湖北省荆州市2家流行性感冒(流感)监测哨点医院监测质量及流感病毒核酸检测阳性率(PR)的影响因素,为提高流感监测质量提供参考。
    方法从中国流感监测信息系统收集 2010— 2018年度荆州市2家流感监测哨点(哨点A、哨点B)的流感样病例(ILI)和病原学监测资料,采用ILI百分比(ILI%)和ILI PR评价2家哨点监测结果。 将医院、病例性别、是否为流行季节、发病与采样时间间隔、采样与检测时间间隔等因素作为自变量,核酸检测结果作为因变量,采用二分类logistic回归分析核酸检测结果的影响因素。
    结果哨点A和哨点B ILI%分别为2.34%和1.34%,差异有统计学意义(χ2=3 096.26,P=0.000)。 哨点A和哨点B的PR分别为13.63%和14.84%,差异有统计学意义(χ2=4.69,P=0.030)。 2家哨点医院ILI%、PR变化趋势均一致(rs=0.568,P=0.000;rs=0.824,P=0.000)。 哨点A和哨点B的ILI%和PR变化趋势一致(rs=0.306,P=0.026;rs=0.477,P=0.000)。 logistic回归分析结果显示,PR与医院(OR=1.15,95% CI:1.05 ~ 1.26)、是否为流行季节(OR=3.19, 95% CI:2.88 ~ 3.52)有关。
    结论荆州市流感监测哨点医院整体运行良好,2家流感监测哨点ILI%与PR均存在差异,监测哨点和流行季节是影响PR的主要因素。

     

    Abstract:
    ObjectiveTo evaluate the surveillance quality of influenza and influencing factors for influenza virus nucleic acid detection in two influenza sentinel hospitals in Jingzhou of Hubei province, and provide evidence for the improvement of the quality of influenza surveillance.
    MethodsThe surveillance data of influenza-like illness (ILI) and pathogens from two influenza sentinel hospitals (hospital A and hospital B) in Jingzhou from 2010 to 2018 were collected from the China Influenza Surveillance Information System, ILI case proportion (ILI rate) and nucleic acid positive rate of ILI cases were used to evaluate the surveillance quality. Factors such as hospital, case sex, season, interval between onset and sampling, interval between sampling and detection were used as independent variables. Pathogen test result of ILI case was used as dependent variables, and the influencing factors was analyzed by two-category Logistic regression.
    ResultsThe ILI rates of hospital A and hospital B were 2.34% and 1.34%, respectively, and the difference was significant (χ2=3 096.26, P=0.000). The influenza virus nucleic acid positive rates of hospital A and hospital B were 13.63% and 14.84%, respectively, and the difference was significant (χ2=4.69, P=0.030). The change trends of ILI rate and nucleic acid positive rate of the two sentinel hospitals were consistent (rs=0.568, P=0.000; rs=0.824, P=0.000). Hospital A and Hospital B had consistent change trends of ILI rate and nucleic acid positive rate (rs=0.306, P=0.026; rs=0.477, P=0.000). Logistic regression results showed that sentinel hospital (OR=1.15, 95% CI: 1.05–1.26) and season (OR=3.19, 95% CI: 2.88–3.52) were associated with the positive rate of influenza virus nucleic acid detection.
    ConclusionThe overall performance of influenza sentinel surveillance was well in Jingzhou. There were differences in ILI rate and positive rate of influenza virus nucleic acid detection between two influenza sentinel hospitals. Sentinel hospital and season were the main factors affecting the positive rate of influenza virus nucleic acid detection.
