摘要
目的从空间设施布局优化的角度探讨疫情下的医院服务区分布与基于服务区设置集中隔离点的方法。方法基于Huff模型描绘了上海市三级医院的服务区空间分布;以最大化覆盖率为目标,采用位置分配模型预测医院选址的优化布局,设置潜在的候选位置。结果在上海市可收治病例的三级医院中,中心地区医院密度高;城乡医院服务区空间分布差异明显,郊区医院的服务区面积大;优化配置布局的结果显示,可在松江区中心新增1家医院,在浦东新区中间区域增加适量医院。结论结合医院服务区分布,隔离点可以设置于各街道中与所属医院相近的位置,明确出现病例时各个隔离点对应送往的医院。优化布局建议在松江区和浦东新区增加三级医院。
Objective To explore the distributions of hospital service areas under epidemic situation and the methods of setting centralized isolation points based on service areas from the perspective of space facility layout optimization.Methods A Huff model was applied to analyze the distributions of service areas of tertiary hospitals in Shanghai.Candidate locations were set to achieve maximizing coverage,and a location-allocation model was applied to predict the optimal hospital location.Results Among the tertiary hospitals that can admit COVID-19 cases in Shanghai,the central area had a high density of hospitals.The distributions of service areas in urban and rural hospitals were obviously different,and the service areas of rural hospitals were large.It was recommended to optimize the allocation of a new hospital in the center region of Songjiang District and an appropriate number of hospitals in the central area of Pudong New District.Conclusion Considering the distribution of hospital service areas,isolation points can be set in the communities close to the affiliated hospitals,and the hospitals corresponding to each isolation point should be clearly identified when a case occurs.It is recommended to optimize the configuration to add tertiary hospitals in Songjiang District and Pudong New District.
