Health Accessibility Mapping: Isochrone and and Network Analysis Approach

Abstract

Abstract—  Every individual has the right to a standard of living that ensures the health, welfare of self and family. One of the important pillars to maintain the quality of life and community welfare is through health services. Accessibility to health facilities shows how health services from a geographical aspect. South Nias Regency was chosen as the study area in this research because it has the second lowest Community Health Development Index (CHI) in North Sumatra Province. Geographic information system (GIS)-based isochrone and network analysis models were used to see how the accessibility of health facilities in underdeveloped districts such as South Nias. The results show that the accessibility of health facilities in South Nias Regency is influenced by the distance to the center of government, which is in the southern part of the district. The further away from the government center, the lower the accessibility of health facilities due to the unavailability of health facilities close to the population. The mode of transportation and road network also affect accessibility, where the driving car mode is an alternative in expanding the range of accessibility in terms of time and the cycling road mode is more effective in being able to reach existing health facilities in terms of distance. Therefore, equal distribution of the number of health facilities needs to be considered for the central and northern parts of South Nias Regency, and the development of road network infrastructure can be improved to reach available health facilities.
