RESUMO
The establishment of a sustainable healthcare system based on residents’ needs is an urgent issue in a rural region. For this purpose, considering the structure of a healthcare system, such as the numbers of beds, doctors, and nurses is important. In addition, the study of healthcare utilization using the date gathered through geographic information systems (GIS) would be very helpful in building such a healthcare system. In Japan, however, there are few published studies available on how health services are utilized. The aim of this paper was to review articles of GIS research on healthcare utilization. We conducted a systematic search of published peer-reviewed literature on PubMed. We found 38 articles that satisfied our inclusions criteria for review. Of them, 12 articles had a map for understanding health needs or demands, 23 articles carried analyses of distance and time for health utilizations, and seven articles had a buffer or database for analyses of healthcare utilization. Most of these articles have dealt with pediatric care and emergency care. Given the aging population in a rural region, we concluded that a more evidence-based approach should be taken to rural health focussing on lifestyle-related diseases.
