Abstract
The purpose of this study was to identify the important factors which determine the correlation between the level of knowledge of medical information concerning home care services for the elderly. The level of knowledge by principal component score was correlated with the record of past medical examinations, educational background, expanded ADL total score, number of information outlets, and number of impersonal media. From the results of multiple regression analysis, the correlation factors were the number of impersonal media, expanded ADL total score, record of present medical examination, and educational background. The multiple correlation coefficient was 0.37. This paper discusses the present state of medical information based on the above results.
