This study proposes a novel method for identifying health care disadvantaged areas and analyzing the spatial disparities of health care accessibility using GIS. Taking Cheongju-si, Chungcheongbuk-do, South Korea as a research case, the current study analyzes disparities in health care accessibility with respect to travel times from patients’ residences to various levels of hospitals, employing origin-destination matrix analysis and iso-area as polygons mapping. Despite efforts to promote the consolidation between rural and urban areas, the study confirmed that significant health care disparities persist. Such issue might not be unique to Cheongju, but may also arise in other urban consolidated cities. This study discusses future research and policy implications for identification of health care disadvantaged areas and improvements to health care workforce supply systems.
