After 1985, the decrease in domestic nursing power progressed gradually. The care for the elderly shifted from domestic private nursing to public nursing-care services when the long-term nursing-care insurance law was enacted in 2000. Because many of the elderly receiving nursing care suffer from chronic ailments of hypertension or the consequences of cerebrovascular disease, etc., cooperation between hospitals and nursing homes is necessary and indispensable. We began exchanging information by E-mail on a trial basis with a special elderly nursing home in April 2009. We aimed to integrate medical care and nursing by sharing medical and nursing information. We concluded that the use of E-mail could serve our purpose. The reason why we reached this conclusion is as follows:The mechanism of the information transmission by E-mail, that also relates to semiotics and narratology, is related to the essence of the description. This mechanism functions as a tool for mutual understanding among hospitals, nursing homes, and families. This also functions as a device to make the medical and nursing experience join. As a result, this mechanism enables the elderly to escape death as dying of sickness in the hospital and to die a natural death in the course of nursing. It is an easy method that can be introduced at a low cost for the purpose of establishing cooperation in medical and nursing care among hospitals, clinics, nursing homes, and nursing support centers, etc. especially in medically underserved remote areas.

To clarify characteristics of home care in rural areas in Japan, we investigated the actual status of home care in a rural area (Asuke town, Asahi town, Inabu town, northern part of Toyota city and Shimoyama village) in Aichi prefecture. The subjects were 149 patients who were under medical care and nursing supervision at home for the last 2 years and a half. Age, sex, ADL, prognosis, principal care-givers of the patients and distance from patients' houses to our hospital were compared with the average data of all the nurse stations in Japan (1996). The percentage of patients over 90 years old was 23.4% in this area as against 13.5% of the national average. Sex and ADL levels were similar to the average. The proportion of females as principal care-givers of patients was 80%, which is about average. However, the proportion ofdaughters-in-law was 51.7%, double of the national average. In 48 cases (32%), the time required to get to the hospital by car was over 31 min. This ratio was 3 times higher than that of the average data, and it took 50 min from farthest patient's house (35km). In prognosis, 66 patients died-44 cases (67%) in hospital and 22 cases (23%) at home.
Our questionnaire survey regarding patients' and care-givers' wishes was responded to by 38 of 47 principal care-givers who utilized our home care and nursing survice program. One half of care-givers were over 60 yearsold and had taken care of a patient for over 5 years. Mental stress, feeding and toileting were major problems most principal care-givers cited. However, they required services at a day-care institution for elderly patients and recovery of used paper diapers. Death at home was wished by 23 (61%) patients and care-givers, if they received enough medial care and welfare services.
These findings revealed that elderly people take care of elderly patients, their houses are far from the hospital and they wish to die at home. More collaboration among all providers of medical care and health and welfare services, and the establishment of an information network are necessary to improve these problems, resulting in safe, acceptable and satisfied home care for patients and care-givers.

  We examined how difficult it would be for the elderly living in mountainous areas to go to the nearest hospital using a Voronoi tessellation representing the mathematical concept of neighborhood. We defined the index of the nursing-care capacity for the elderly as the ratio of the number of caregivers to the number of the elderly receiving nursing-care.
  The mean age of those who drive to the hospital by themselves worked out at 70±9.8 years. Meanwhile, that of those who go to the hospital by bus or taken to hospital in a car driven by a family member came to 80±7.0years. The latter was significantly older than the former.
  The areas of the Voronoi tessellation generated by patients' places of residence were divided into three groups according to the size. The plots of these three groups of the the places of residence on the map had a three-layer and doughnut-like structure, i. e., inner-, middle-, and outer-layer.
  The index of the nursing-care capacity in 2008 was less than 1.0 for the patients under 80 years of age. This means that when those who were at the age of 50 in 2008 become old and need nursing-care, access to the hospital will become harder to them than at present. For those who are over 80 years of age and live in the outer layer that is far away from arterial road, it will be almost impossible.
  These findings suggest that outpatient care with transportation assistance by a family member at present should be reconsidered because of the future lack of care personnel. It would also be necessary to consider the welfare of older people from the geographical point of view in order to manage the problems concerning the various physical and sociological difficulties of the elderly.
