Recently, the deficiency of emergency care system has become a social issue by the decline in the number of emergency hospitals due to the shortage of doctors in Japanese rural communities. Although the number and distribution of doctors were taken into account when secondary-medical care areas were designated, real transportation time required to reach the emergency hospitals has not been considered enough. The main objective of this study was to clarify the characteristics of accessibilities to emergency hospitals by secondary-medical care sectors in Shimane Prefecture, excluding islands, using a Geographical Information System. We categorized areas within 3 min., 10 min., and 30 min. transportation time to evaluate the accessibility to emergency hospitals by calculating the population of each area. The western areas of Shimane such as Ooda, Masuda and Hamada had a higher proportion of residents with over 30 minutes of transportation time than the eastern parts. This result indicated that there was a disparity in terms of accessibility to emergency hospitals between the eastern and western parts of Shimane Prefecture. Furthermore, we estimated that residents in the Ooda area were forced to take longer transportation time after the closure of the Ooda City Hospital emergency unit. Our study suggested that not only the discussion of healthcare resources but also the consideration of accessibilities to emergency hospitals in a region was important for the planning of health and medical service.

Health care plan has been established in each secondary medical area. Although health care plan should be focused on needs of people live in such units, studies with a view from residents’ perspective have not always been considered adequately. The aim of this study was to examine the factors that effect on utilization of health care facilities located outside of the secondary medical area in a rural region. The data included 515 patients with hypertension, 253 patients with hyperlipidemia, and 104 patients with diabetes. Factors relating utilization of health care facilities were assessed by age, sex, employment, number of diseases, body mass index (BMI), carotid plaque score, HbA1c, distance to the nearest clinic, and distance to the nearest bus stop. We conducted a logistic regression analyses of that data divided into two groups; car use and non car use. The result showed that sex, BMI, carotid plaque score and distance to the nearest bus stop were statistically significantly associated with the utilization of health care facilities located outside of the secondary medical area in patients with car use. Whereas, there were no statistically significantly associations in patients with non car use. Our findings suggested that it is important to consider health utilization of patients with lifestyle related diseases for making sustainable health care plan.

As is often the case with rural communities in Japan, a dearth of health resources poses a serious problem in a mountainous region of Shimane Prefecture. Although a medical care plan focusing on needs of people should be devised with a view to building up a sustainable health care system, studies have not always adequately been pursued. The aim of this study was to assess the data on the patients with lifestyle-related health problems to and from health care facilities. A Geographic Information System was used for measuring the travel time and road distance. The data for 255 patients with hypertension, 114 patients with hyperlipidemia, and 42 patients with diabetes were amassed. The results showed that the average travel time and distance were much longer in patients with diabetes than those with hypertension. Statistically no significant difference was observed in severity of diabetes (HbA1c, BMI and LDL-c) and blood pressure levels between patients who received regular treatment at clinics in the two towns and those who went all the way to clinics outside of the towns. In addition, compared with the patients with diabetes aged 75 years or over, the average travel time and road distance for aged of 74 years or younger were much longer. Similarly, compared with the patients with hypertension aged 75 years or over, the average travel time and road distance for aged of 74 yeras or younger were also much longer. These results indicated that the diabetics and the elderly age 74 or younger tended to go to health facilities beyond the secondary-medical care zone. These findings also suggested that a closer cooperation between facilities in the neighboring secondary-medical care zones to improve the quality of medical services and support general practitioners to review the existing disease management program would make it possible to cope with the present situation.

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.
