Spatial layout optimization of medical institutions based on location-allocation modeling

Objective To analyze the spatial layout and accessibility of secondary or tertiary medical institutions in coastal cities of Beibu Gulf,Guangxito provide reference for government health planning.Methods Using the GIS software,we analyzed the current spatial layout of 33 secondary and tertiary general hospitals and 124 township-level residential areas with the OD cost matrix.The accessibilities for residential areas to medical institutions were calculated based on different impedance cutoff values.The minimized facility point in the location-allocation model was used to identify candidate sites for new healthcare providers to be established in the medical institution blank areas.Results Secondary and tertiary general hospitals were clustered in the central areas of cities and counties with dense road networks.Residents in eleven townships were inaccessible to hospitals within 50,000 m and in 8 townships were inaccessible to hospitals within 60 min,and the accessibility of hospitals has been significantly improved after the proposed addition of 9 medical facilities.Conclusions The servicing areas of medical institutions are overlapped in central areas of cities,and the distance to the secondary and tertiary hospitals is long in remote areas.The emergency medical service is not available in some residential areas.Therefore,the spatial layout of medical resources should be further optimized to meet the healthcare needs of residents.
