Optimizing nation-wide locations of dialysis centers: a geographic information system-based approach to improve healthcare accessibility and availability

To our knowledge, this is the first study to apply GIS to national patient-based data for assessing dialysis center accessibility and utilization. Our findings demonstrate how GIS integration with national registries can inform equitable healthcare planning and facility allocation. This approach offers policymakers a scalable, technology-driven strategy to optimize resource distribution, correct healthcare inequities, and improve accessibility for dialysis patients.
