目的对2011-2013年3个监测年度新乡市哨点医院所采集的流感样病例样品质量进行评价,以指导下一步监测工作。方法对流感监测管理系统中的ILI样品信息的周/月采样量,采样时间分布,患者发病至采样时间间隔,采样至送检时间间隔以及2011-2013年督导资料中采样病例临床描述进行分析,对照《全国流感监测方案(第二版)》的要求进行样品质量评价。结果采样量合格率为9 1.92%,每个工作日都能采集ILI样品,避免集中采样,98.79%的ILI样品均在患者发病3 d之内采集,84.82%的样品在采集后2 d内送至流感网络实验室,81.97%的采样病例符合ILI诊断标准,各项指标从2011-2013年逐步提高。结论新乡市流感样病例样品质量较高,但仍需进一步改进。
Objective To evaluate the quality of samples collected from the sentinel hospitals in Xinxiang City during the three monitoring years from 2011 to 2013 to guide the further monitoring. Methods The weekly / monthly sampling of ILI sample information in influenza surveillance management system, sampling time distribution, patient onset to sampling time interval, sampling to submission time interval and the clinical description of sampled cases from 2011-2013 supervision data were analyzed. The quality of the samples was evaluated against the requirements of the “National Influenza Surveillance Program (Second Edition)”. Results The passing rate of sampling was 9 1.92%. ILI samples were collected every working day to avoid concentrated sampling. 98.79% of ILI samples were collected within 3 days after onset of the disease and 84.82% samples were sent within 2 days after the acquisition To influenza network laboratory, 81.97% of the sampling cases meet the ILI diagnostic criteria, the indicators gradually increased from 2011-2013. Conclusion The samples of flu-like illness in Xinxiang City are of high quality, but still need to be further improved.
