In order to clarify the characteristics of the area where the visiting nursing station is located, we conducted a study to identify the regional characteristics of the visiting nursing station in Ishikawa Prefecture, using geographical information system(GIS). We mapped the elderly population, aging rate, and location data for the visiting nursing station using QGIS, and created trade areas(Voronoi diagrams). The aging rate for each trade area is 22.4%(min 8.8% to max 44.6%), about 5 times. The difference in area is about 850 times as large as the central value of 9.2 km2(min 0.5 km2 to max 423.2 km2). In addition, there was a tendency for stations with a large trade area to have a higher aging rate than that of smaller stations. Understanding the characteristics of the area surrounding visiting nursing stations using GIS facilitates the clarification of potential needs and opportunities for providing visiting nursing services that are suitable for each area.
为了阐明访视护理站所在区域的特征，我们利用地理信息系统（GIS）开展了一项研究，以确定石川县访视护理站的区域特征。我们使用QGIS绘制了老年人口、老龄化率以及访视护理站的位置数据，并创建了商业区（Voronoi图）。每个商业区的老龄化率为22.4%（最小值8.8%至最大值44.6%），约为5倍。面积差异约为中心值9.2平方公里（最小值0.5平方公里至最大值423.2平方公里）的850倍。此外，商业区大的护理站老龄化率往往高于商业区小的护理站。利用GIS了解访视护理站周边区域的特征，有助于明确适合各地区的访视护理服务的潜在需求和机会。
