Equity in healthcare is ensured to a large degree by access to public hospitals. By considering the spatial distribution of residents, the efficiency of such hospitals can be increased in terms of their locations and capacities. Conversely, accessibility metrics are a powerful tool for assessing the interaction between spatial distribution and supply and demand. Indicators from the Floating Catchment Area (FCA) family, a set of measures built on the gravity model and used to quantify spatial accessibility, have proven to be very suitable for studying spatial accessibility to health services. In this study, we use various FCA metrics to assess spatial accessibility to public hospitals by car. Our result shows spatial segregation in accessibility values. The result could be a starting point for the government to ensure equitable distribution of health services by car.
