We retrospectively analyzed the response time of emergency teams(EmAT) in Niigata City according to geographical distribution using 25,713 ambulancerecords for 2007 and 2008. When these data were compared to the area-specific mortalitystatistics, we found that the risk of mortality from cerebrovascular disease (CbrVD) washigh in areas where emergency response teams took a long time to transfer patients tohospitals. Subsequently, we selected 1043 stroke cases from all ambulance records for oursimulation study. In Niigata City, there are 9 major emergency hospitals for strokemanagement. We presumed that patients who experienced stroke would be admitted to anyof these hospitals and thus calculated the estimated EmAT (eEmAT) for transfer to eachhospital. When 22 areas in Niigata City were classified into 4 groups on the basis of eEmAT,the average eEmAT in the area-group with the longest eEmAT was higher by 12 minutesthan that for the area-group with the shortest eEmAT. This disparity could be reduced byan average of 4.5 minutes if an additional major hospital would be established in the areaswith the longest eEmAT, which could result in the reduction of CbrVD-related mortalityrates by 20%.

我们使用2007年和2008年的25,713条急救车记录，根据地理分布，对新泻市急救队(EMAT)的反应时间进行了回顾分析。当将这些数据与特定地区的死亡统计数据进行比较时，我们发现，在应急小组将患者转移到医院需要很长时间的地区，脑血管疾病(CbrVD)的死亡风险很高。随后，我们从所有的救护车记录中选择了1043例中风患者进行模拟研究。在新泻市，有9家主要的急诊医院进行中风管理。我们假设发生中风的患者将被送往这些医院中的任何一家，从而计算出转移到每家医院的估计EMAT(EEmAT)。根据eEmAT将新泻市的22个地区分为4组，eEmAT最长的地区组的平均eEmAT比eEmAT最短的地区组高12分钟。如果在eEmAT时间最长的地区增设一家大型医院，这一差距可以缩小到平均4.5分钟，这可能会导致CbrVD相关死亡率降低20%。
