Regulatory effects of health examination programs on medical expenditures for the elderly in Japan.

In order to evaluate if there is any correlation between the use of general medical examination programs organized by each community under the Health Service Law for the Elderly, and the medical expenditures for the elderly, an analysis was conducted based on 97 communal data of Fukuoka prefecture, Japan in 1991. According to the results, the use of health examinations showed a statistically significant negative correlation with the medical expenditures for the elderly both for in- and outpatient services. The analysis of the medical expenditure components has clarified that this negative correlation is mainly due to the low utilization rate of services at medical facilities among the communities with a high participation rate in the examination. A part of this low utilization rate could be explained by the complementary effect of the examination program as an alternative for the elderly instead of going to a medical facility for consultation. The present result suggests that a community health service program could decrease the demand for medical services of the elderly.
