Sample geospatial models showing patterns of community healthcare utilizations. Map A. Hispanic settlement patterns by census tract (target clinic noted with circle). Map B The geographic retrofitting model demonstrates the actual service area for the target clinic (note - many patients come to the clinic from distant parts of the city). Map C Complete models showing areas in need of improved access to primary care based on the retrofitting model of the safety-net, settlement patterns, and inappropriate ED utilization identified by the NYU algorithm.
