从一起农村麻疹爆发分析疫情被动监测系统的工作状态

Measles Surveillance in a Rural Area:Assessment of a Passive Reporting System

将一起农村麻疹爆发流行中疫情被动监测结果与流行结束时的爆发调查进行比较，发现被动监测从流行开始到高峰出现均有一个月的迟报时程，未能发现重灾区，小年龄组漏报偏多加重了发病年龄高移的错觉。疫情被动监测体制日益难于被卫生资源不足的农村基层卫生组织和临床医生所接受。处方诊断制以其能把住漏记关、基层易于接受、报告及时和廉价见长，对疫情监测改革将有重要意义。

Comparison of the data provided by thepassive epidemic reporting system( PERS )with those of epidemicologic investigationduring the outbreak of measles in a ruralarea,Rongshui County,from November 26,1992 to May 10,1993 indicated that the PERSdelayed the report one month during the out-break,failed to describe the time ,place and age distributions correctly. The main draw-backs of the PERS were tediousness and delay.The reformed active surveillance system withdiagnostic recipe made the reporting precedures much simpler and well acceptable by the phy- sicians.
