摘要
院前急救医疗服务一直是城市医疗公共服务建设的重要内容,其城市院前急救医疗站点空间分布合理与否,直接影响急救医疗服务的效用。本文综合利用地理国情数据、交通大数据和统计数据,提出了以出行便利度、均等度、人口覆盖度和人口协调度4个空间测度,对急救医疗站点的空间分布特征进行分析的方法,用于识别现有站点布局存在的问题。针对存在的问题,结合现有站点和潜在站点,研究了全局和局部优化方法。以合肥市为例进行验证,结果表明站点空间特征分析方法能够有效识别现有站点布局存在的问题,站点布局优化的结果能够有效提高服务效用。
Prehospital emergency medical service has always been an important part of urban medical public service construction.Whether the spatial distribution of urban prehospital emergency medical stations is reasonable or not directly affects the effectiveness of emergency medical services.In this paper,we proposed a method to analyze the spatial distribution characteristics of emergency medical stations based on four spatial measures,namely,travel convenience,equality,population coverage and population coordination,by making comprehensive use of geographical national data,transportation big data and statistical data,to identify the problems existing in the layout of existing stations.Aiming at the existing problems,combined with existing sites and potential sites,we studied the global and local optimization methods.Taking Hefei City for example,the verification results show that this method can effectively identify the existing site layout problems,and the site layout optimization results can effectively improve the service effectiveness.
