目的分析我国群体性不明原因疾病事件的报告概况和报告质量。方法对2004-2009年间,通过突发公共卫生事件报告管理信息系统报告的群体性不明原因疾病事件进行描述性分析;并按照初步建立的完整性、准确性和时效性定义,评价其报告质量。结果 2004-2009年间,全国(不含港澳台地区)共计有27个省(自治区、直辖市)的112个县(区)报告不明原因疾病事件139起。对符合纳入标准的137起事件分析显示,2004年和2005年报告数合计占报告总数的88.32%,浙江、云南、福建和北京4省(市)报告数合计占报告总数的43.07%;82.48%的事件报告不完整,在有详细信息的事件中45.57%报告不准确;从首次报告首例病人到首次报告事件发生的时间间隔为0 min至70 d,62.07%的事件小于1 d;从首次报告接到报告到创建报告的时间间隔为12 min至298 d,56.39%的事件介于1～6 d之间。结论我国的群体性不明原因疾病事件报告具有明显的时间、地区集中性,虽近年来报告水平有所提高,但总体报告质量有待改进;现有报告规范有待完善。
Objective To analyze the general situation of reports and the quality of reports of group-unknown disease events in our country. Methods Descriptive analysis of group-specific unexplained disease events reported from the Emerging Public Health Incident Management Information System between 2004 and 2009 and the quality of their reports were evaluated in accordance with the initial definitions of completeness, accuracy and timeliness. Results From 2004 to 2009, a total of 112 counties (districts) of 27 provinces (autonomous regions and municipalities directly under the Central Government) in the whole country (excluding Hong Kong, Maucao and Taiwan regions) reported 139 unidentified disease events. The analysis of 137 incidents meeting the inclusion criteria showed that the total number of reports in 2004 and 2005 accounted for 88.32% of the total number of reports, while the total number of reports in Zhejiang, Yunnan, Fujian and Beijing in 4 provinces accounted for 43.07% of the total; 82.48% Reported 45.57% of the cases with inaccurate reports inaccurate; the time interval from the first reported patient to the first reported incident was 0 to 70 days, and 62.07% of events were less than 1 day; from the first time The time interval from the receipt of a report to the creation of a report was 12 to 298 days, with 56.39% of events ranging from 1 to 6 days. Conclusions Our report on group-based unexplained disease events has obvious time and regional concentration. Although the level of reporting has been raised in recent years, the overall reporting quality needs to be improved. The existing reporting norms need to be improved.
