Outline of Final Research Achievements

This study developed the methods to quantify and visualize disparities in supply-demand balance of tertiary emergency care in Japan by utilizing Geographic Information Systems (GIS). We proposed two indicators: 1) Coverage rate: the proportion of patients within 45 minutes to EMCs by ambulance, and 2) Institute-to-Patient Ratio (IPR): 1 / the number of patients within 45 minutes to EMCs. We believe our study may contribute to secondary data utilization and evidence-based decision making for examining resource allocation in emergency medicine.
