摘要: 目的 探索集装箱医学媒介生物疫情管理的新方法,及时、有效地发现疫情的变化趋势并进行警示。方法 采用质量控制图法计算集装箱媒介疫情截获率的平均值、移动极差均值、警告限以及控制限,并做出单值-移动极差控制图。结果 根据2006年数据制作分析质控图,发现6月份集装箱媒介疫情截获率超过上控制限,剔除异常点后,制作管理质量控制图,并对2007年1-5月集装箱疫情截获率进行监测,发现2007年4月份疫情截获率明显超标,提示检验检疫部门对于高疫情截获月份入境的集装箱,需要加强查验力量重点开展检验检疫,防止媒介疫情通过集装箱携带传入国境。结论 质量控制图可以快速、简便、动态地对集装箱疫情截获情况起到警示作用,有助于检验检疫部门及时、合理地分配力量开展口岸集装箱检验检疫监管工作。

Abstract: Objective To explore a new scientific method of medical-vector management, and grasp effectively the change of epidemic situation in time to provide a early warning. Methods The values of ,Rs,UWL,LWL,UCL,LCL were calculated by the method of quality control chart(QCC), and then X-Rs chart was drawn. Results According to the data in 2006, the analytical QCC was drawn to find that the interception rate of medical pest exceeded the UCL in June of 2006. After elimination abnormal points, it was found that the interception rate in April 2007 exceeded obviously standard value compared to that of January to May 2007 analyzed by the management QCC. It suggested that the CIQ Institution should enhance the inspection and quarantine to the disembarkation containers to prevent the introduction of vector. Conclusion The QCC can make precaution to epidemic situation captured from entry containers and help to CIQ Institution enhancing the inspection and quarantine to containers in the ports.
