Outline of Final Research Achievements

This study investigated the impacts of recent reforms to the long-term care insurance system on older adults and their caregivers. The main findings are as follows. The increase in the co-payment ratio for long-term care service use fees has curtailed service use among 20%-payers who were certified as care-level 4 or higher. Approximately 20% of primary caregivers of older adults in care-level 1 or 2 wish to be admitted to a nursing home, and older adult's ADL dependencies and problematic behaviors of dementia, and caregiver's age and economic status were related to their desire for admission. Use of home health care services increased positive feelings of caregivers providing medical care. Problematic behaviors of dementia and high co-payment rates for service fees were associated with unmet needs for service utilization, and unmet needs worsened caregiver's mental health. The percentage of those who positively evaluate the long-term care insurance system has decreased over time.
