Abstract

|
|
Objectives: This study aimed to analyze people’s accessibility to medical institutions providing national gastric cancer screening services in Gangwon-do using a geographic information system(GIS).
Methods: To assess the spatial accessibility, network analysis was applied. Two types of network analysis-Service area analysis and origin-destination cost matrix(OD-cost matrix)-were applied to create network dataset.
Results: The results of the analysis of the service area revealed that it took more than 60 minutes each to reach tertiary hospitals and general hospitals from 74.4% and 9.6% of Gangwon-do areas, respectively. Similarly, it took more than 60 minutes each to reach hospitals and clinics from 4.2% and 3.4% of Gangwon-do areas, respectively. The results of the OD-cost revealed that there were large regional variations in distance and time taken to reach the medical institutions.
Conclusions: there were regional variations of spatial accessibility between Si and Gun in Gangwon-do.
