Abstract
The medical service situation of out-patient medical treatment in 43 cities and towns of Kagawa Prefecture was analyzed, and classified using principal component analysis. When viewed by the average of 43 cities and towns, the rate of dependence on one's own area was 48.4%, the rate of patients from one's own area at 73.3%. Generally, the self-sufficiency of medicalcare was high, and the medical treatment zone was wider in the city region compared with the county region. The medical service situation in 43 cities and towns was classified into 5 types such as the Nuclear type: 4 cities; the Base type: 1 city and 4 towns; the Averageother type: 18 towns; the Peripheral type (the Insular region type: 3 towns; the Peninsular or remote place type: 2 towns; the Satellite city type: 2 towns) and the Depopulated type: 9 towns, using principal component analysis with the rate of dependence on one's own area, rate of patients from one's own area, dependence entropy and medical treatment zone entropy as the input data.
