2009-2015年白银市流行性感冒监测质量评估

Evaluation of influenza surveillance in Baiyin,2009-2015

  • 摘要: 目的 了解白银市流行性感冒(流感)监测网络运行情况,评估流感监测质量,探索市级评估方法。方法 依据《全国流感监测工作质量评估方案》,结合市级实际情况,选取国家级哨点医院、市级网络实验室和暴发监测管理三方面指标,对白银市各年度流感监测质量进行量化评分。结果 2009-2015年,白银市流感监测质量综合评估平均得分为73.25分,2015年最高,为88.75分。两家哨点医院流感样病例(ILI)及时报告周次比例一直在90.00%以上,无缺报、漏报,采样合格周次比例2013年以来达90.00%以上(趋势2=42.613,P=0.000;趋势2=17.356,P=0.000),标本送检及时率分别为53.91%和40.89%。市级网络实验室核酸检测及时率呈逐年上升趋势(趋势2=272.189,P=0.000),送检毒株复核一致率从73.08%上升至98.00%以上(趋势2=20.129,P=0.000),阳性标本亚型鉴定比例、接受国家盲样考核正确率达100.00%,但流感病毒的鸡胚分离能力需要提高,向国家流感中心及时送检毒株数量不足。全市7年报告28起ILI/流感暴发疫情,监测管理情况良好。结论 白银市流感监测质量明显提高,但仍需加强哨点医院ILI监测,市级网络实验室在原有工作基础上进一步提高流感病毒的鸡胚分离率。

     

    Abstract: Objective To evaluate the performance of influenza surveillance in Baiyin, Gansu province, and provide evidence for the influenza surveillance evaluation at city level. Methods According to the National Influenza Surveillance Evaluation Protocol and local situation, the performance of influenza surveillance in Baiyin was evaluated by using the data from sentinel hospitals, laboratory network and outbreak surveillance. Results From 2009 to 2015, the average score of influenza surveillance comprehensive evaluation was 73.25, the highest score was 88.75 in 2015. In two sentinel hospitals, the timely weekly reporting rate of influenza like illness (ILI) was always 90.00%, no underreporting occurred, the weekly qualified sampling rate had been 90.00% since 2013(trend2=42.613,P=0.000; trend2=17.356, P=0.000), the timely detection rates of samples were 53.91%, 40.89% respectively. In local network laboratories, the timely detection rate of nucleic acid of influenza virus showed an increasing trend (trend2=272.189, P=0.000), the verifying consistent rate increased from 73.08% to 98.00%(trend2=20.129, P=0.000), all the positive samples were subtyped and the correct rate of blind sample assessment was 100.00%, but the chick-embryo isolation of influenza virus needed to be improved, and the virus strains timely sent to national influenza center were insufficient. A total of 28 ILI outbreaks were reported during this period, the surveillance management was performed well. Conclusion The influenza surveillance quality has been improved significantly in Baiyin, but it is still necessary to strengthen the surveillance in sentinel hospitals, and the chick-embryo isolation rate of influenza virus should be further improved in local network laboratories.
