| 摘要:目的：借助地理信息系统，对北京市Z区医疗设施布局及居民就医空间可达性进行分析研究，旨在为促进医疗资源合理布局、提高居民医疗服务公平性提供决策参考。方法：基于ARCGIS软件，采用两步移动搜寻法模型，对北京市Z区的居民点对不同等级医疗机构的空间可达性进行测算。结果：Z区人口及医疗床位资源主要分布在中西部几条核心街道地区；空间可达性呈典型的单核辐射向四周的布局状况。一级医疗机构资源空间可达性东部更高，二、三级医疗机构则西部更高。结论：Z区医疗床位资源总量有待进一步提高。建议增加对西部地区一级医疗卫生机构的卫生资源投入，此外，通过建设医联体增强三级医院与基层医疗机构协作，从而促进优质资源下沉至东部地区，将有助于提高全区医疗卫生资源布局合理性。 |

| Abstract:Objective:To analyze the spatial distribution of medical facilities and the spatial accessibility of residents' medical treatment in Z District of Beijing with the help of geographic information system (GIS), so as to provide provide decision-making reference for promoting the rational distribution of medical resources and improving the fairness of residents' medical services. Methods:Using ARCGIS software, the two-step floating catchment area method was adopted to calculate the spatial accessibility of residential areas to different levels of medical institutions. Results:The population and hospital bed resources of Z District are mainly distributed in several core streets in the Central and Western regions. The spatial accessibility presented a typical layout of monocycle radiation to the surrounding areas. The spatial accessibility of the resource space of primary medical institutions is higher in the East, while that of secondary and tertiary medical institutions is higher in the West. Conclusions:The total amount of hospital bed resources in Z District needs to be further improved. It is suggested that the input of health resources allocated to primary medical institutions in the western region should be increased. In addition, through the construction of a Medical Consortium, the cooperation between tertiary hospitals and primary medical institutions should be strengthened in order to promote the sinking of high-quality resources allocated to the eastern region, which will be helpful in the improvement of rationality of medical and health resources allocation in Z District of Beijing. |
