Evaluation of influence for community emergency medical service after the closure of emergency hospital: with basic analysis by GIS

摘要本研究以岛根县急诊医院为研究对象，利用实际急诊识别资料与地理资讯系统（GIS），评估其可达性。我们收集了来自四个消防部门的紧急识别数据，然后评估了从最初响应紧急呼叫到到达现场的时间以及救护车从现场开车到医院的时间。此外，我们在3分钟内对区域进行了分类。10分钟。， 30分钟。超过30分钟。基于GIS的交通时间评价急诊医院可达性。根据我们的分析，首先我们确认，在一些消防部门区域，与其他时区相比，患者在工作日晚上被迫花费更长的运输时间。其次，我们发现各二级医疗护理区到急诊医院的交通时间存在差异，大田区估计居民在可达性方面受到急诊单位关闭的影响。

The purpose of this study was to evaluate the accessibility to emergency medical hospitals in Shimane Prefecture by using actual emergency recognition data and GIS. We gathered emergency recognition data from four fire departments and then evaluated the time from initial response to the emergency call to the arrival at the scene and the time an ambulance drives from the scene to hospitals. Additionally, we categorized areas within 3 mins., 10 mins., 30 mins. and over 30 mins. transportation time to evaluate the accessibility to emergency hospitals by using GIS.As result of our analysis, firstly we confirmed patients were forced to take longer transportation time in weeknights, compared to other time zones in some fire department areas. Secondly, we found there was a disparity of transportation time to emergency hospitals among secondary medical care zones and estimated residents in the Ohda area were influenced by the closure of the emergency unit in terms of accessibility.
