Studies on the geomedical health care system have become more important in medical geography. Geographical concepts and methods have been used to regulate issues regarding the placement of medical facilities, more specially in addressing the need for balance between patient needs and needs of medical resources. To create and build an effective geomedcial health care system, a number of essential factors must be considered, including efficient organization of health care institute, physical environment, population, government regulation, economic status, culture, education, public transport, etc. The gap which exists between supplement of medical resource and needs of the patients are affected by psychological and physical environmental barriers. Playing a crucial part in this gap is the distance patient and medical facilities. The purpose of this study is threefold: 1) to build a geomedical health care system model. 2) to analyze the relative factors of medical resources in central Taiwan, 1981-1990. 3) to analyze the spatial relationship between patients and hospital in central Taiwan, 1981-1990. Results will support the concept that population and distance between patients and hospital are the two most significant factors affecting the geomedical health care system in central Taiwan, 1981-1990.
