Long-term effects of home-based bench-stepping exercise training on healthcare expenditure for elderly Japanese.

BACKGROUND: We examined the long-term effects of home-based bench-stepping exercise training on total healthcare expenditure (TOHEX) and number of outpatient visits (NOVIS) in elderly adults. METHODS: A total of 189 elderly Japanese (age 73 ± 4 years) participated in this study. They were randomly assigned to either an exercise or control group. TOHEX, NOVIS, and outpatient expenditure (OPEX) were evaluated every 6 months from 1 year before the start to the end of the intervention period, as well as 1 year after the end of the intervention. The exercise group was encouraged to perform home-based bench-stepping exercise training on most, and preferably all, days of the week for 18 months. RESULTS: The exercise group showed significant increases in lactate threshold as compared with pre-intervention values. There were no significant differences in TOHEX, OPEX, or NOVIS between the exercise and control groups 1 year before the start of the intervention, and the values remained similar during the first 12 months of the intervention period. However, at 18 months, TOHEX, NOVIS, and OPEX were significantly lower in the exercise group than in the control group (TOHEX: 170 007 ± 192 072 vs. 294 705 ± 432 314 yen, P = 0.008; NOVIS: 19.2 ± 26.3 vs. 28.2 ± 32.1 days, P = 0.012; OPEX: 132 973 ± 132 016 vs. 187 799 ± 158 167 yen, P = 0.005). CONCLUSIONS: The data indicate that a long-term home-based bench-stepping exercise program can reduce healthcare expenditure in elderly Japanese.

[Changes in community health and welfare services with introduction of the long-term care insurance system in Japan].

OBJECTIVE: In Japan, a long-term care insurance system for elderly people was introduced in April, 2000. We have conducted a survey using a questionnaire in order to explore consequent changes in community health and welfare services. METHODS: We sent questionnaires to all municipal governments (671 cities, 1,991 towns, 567 villages and 23 wards) in Japan in November, 2001, and obtained replies from 441 cities (response rate: 65.7%), 800 towns (40.2%), 197 villages (34.9%), and 16 wards (69.6%). The questionnaire included questions concerning the budget and manpower for community health and welfare services, the state of the long term care insurance system, and the activities of public health nurses. RESULTS: A total of 57% of all municipal governments was found to be carrying out the long term care insurance program in collaboration with other governments. In order to clarify the changes in welfare services for elderly people from the budgetary viewpoint, we calculated the ratios of the 2000 and 2001 fiscal budgets applied for welfare services for elderly people, in comparison with the 1999 fiscal year. The budgets for elderly people declined to about 40% in 2000 and 2001 compared with 1999, since the budget for care services was transferred to the account of the long term care insurance system. The activities of public health nurses employed by municipal governments were not affected by the introduction of long term care insurance system. About 80% of all municipal governments suggested that both the amounts of care services received by each elderly people and the number of elderly people who received care services were increasing, and about 70% indicated that the quality of care services was improved with introduction of the long term care insurance system. DISCUSSION: Most municipal governments consider that introduction of the long term care insurance system has had a good influence on community health and welfare services. Moreover, our results suggest that the long term care insurance has a beneficial impact on care services themselves.
