目的通过分析评价北京市不明原因肺炎病例监测的情况,为做好人禽流感监测提出建议。方法对北京市2005～2006年报告的7例不明原因肺炎病例进行分析,计算从发病到入院、诊断、报告等时间间隔,并评价不明原因肺炎监测报告的准确性和及时性。结果2005～2006年北京市各级医院共计报告不明原因肺炎病例7例,报告时间集中在2005年11月～2006年4月间。所有病例最后诊断均排除人禽流感。7例不明原因肺炎病例从发病到首诊、从发病到入院、从发病到诊断等时间间隔均较长。其中从发病到首诊平均8d,而从入院到诊断平均要5d。在北京首诊的病例时间或曾到3家及以上医院就诊的病例时间间隔相对较长。所有病例报告及时,有3例病例在临床表现和(或)实验室检查结果中均有部分指标不符合诊断标准,准确性有待提高。结论应该加强人员培训,提高不明原因肺炎病例监测的准确性;不明原因肺炎病例从发病到诊断时间较长,难以及时发现禽流感疫情。
Objective To analyze and evaluate the surveillance of pneumonia cases with unexplained causes in Beijing and make recommendations for the monitoring of human bird flu. Methods Seven cases of pneumonia of unexplained pneumonia reported in Beijing from 2005 to 2006 were analyzed and the time interval from onset to admission, diagnosis and reporting was calculated, and the accuracy and timeliness of the pneumonia report with unknown causes were evaluated. Results From 2005 to 2006, hospitals of all levels in Beijing reported a total of 7 cases of unexplained pneumonia, the report time concentrated in November 2005 ~ April 2006. The final diagnosis of all cases ruled out human bird flu. 7 cases of unexplained pneumonia cases from the onset to the first visit, from the onset to admission, from the onset to diagnosis interval are longer. Which from the onset of the first visit to an average of 8d, and from admission to the diagnosis of an average of 5d. The time between the first case visit in Beijing and the third or above hospital visit was relatively long. All cases reported in a timely manner, there are 3 cases of clinical manifestations and (or) laboratory test results in some of the indicators do not meet the diagnostic criteria, the accuracy needs to be improved. Conclusions Staff training should be strengthened to improve the accuracy of surveillance of pneumonia of unknown cause. It is difficult to detect the outbreak of avian influenza in time from the onset of pneumonia to the diagnosis of unexplained pneumonia.
