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.

Early detection of third-generation cephalosporin-resistant bacteria in blood culture tests influences the choice of antimicrobial agents. We report on our hospital’s system for early reporting of third-generation cephalosporin-resistant bacteria and its utility. The hospital operates a 24-h simple cefpodoxime (CPDX) testing system, where the content of a sample container with a positive blood culture result is smeared on a CA Sheep Blood Agar/VCM Chocolate EX II fractionation medium, and an antibiotic susceptibility test (AST) disk (Sensi-Disk CPDX) is placed at the center of the medium and incubated. The presence or absence of third-generation cephalosporin-resistant bacteria is estimated from the diameter of the growth inhibition zone. The physician in charge of AST makes comments on the chart based on the simple CPDX test results. The sensitivity of the simple CPDX test for detecting third-generation cephalosporin-resistant bacteria, based on AST results, was 95.5%. Among patients with failed antimicrobial therapy, the rate of switching antimicrobials before the AST results were known was 57.9% in cases where there were comments made by the physicians in charge of AST, compared with 42.9% in cases without comments. These results suggest that the simple CPDX test enables early and accurate detection of third-generation cephalosporin-resistant bacteria, facilitating early switching of antimicrobial agents through collaboration with physicians in charge of AST.
