Measuring Emergency Care Network Coverage with Location-Allocation Models and GIS
The objective of this study is to measure how the Nova Scotia Emergency Care Network, consisting of Emergency Departments (EDs) and ambulance services, covers the population, and provide a tool to evaluate changes to the system. This study uses location-allocation models including the P-median problem (PMP), P-centre problem (PCP), location set covering problem (LSCP), and the maximal covering location problem (MCLP). Distance is measured in kilometres following the road network, and the population is represented as points that are assigned to an ED. We analyze the existing network by computing the population-weighted travel distance of the population to each facility, the maximum distance any person must travel, and the number of people within a specified distance from a facility. We also consider several proposed changes to the network and compute the degree of improvement expected using these metrics.
