Outline of Research at the Start

本研究「在宅認知症高齢者におけるリハビリテーションを含む介護サービス利用の長期的 効果検証」では、自宅に住む認知症高齢者の介護サービス利用の実態、及びそれらの利用による効果検証を、大規模データベースを用いて行うものである。中でもリハビリテーション 効果の検証を取り上げて行う。
自治体が保有する医療介護データベースを整備し、その後分析を進める。

Outline of Final Research Achievements

This study aimed to investigate the effect of rehabilitation on cognitive function in older adults with dementia. The study utilized medical and long-term care insurance data held by a municipality. A total of 3,487 individuals (with a mean age of 86 years) were analyzed with a follow-up period of 5 years. The study findings suggested that rehabilitation showed a tendency to improve cognitive function, although no statistically significant effect was observed.

Academic Significance and Societal Importance of the Research Achievements

研究の結果として、訪問や通所でリハビリテーションが認知機能低下抑制に効果を与えるということは観察されなかった。統計学的な限界もあるが、これらの知見をもとに今後はさらに他のサービスとの併用することでの抑制効果などを検証することで、認知機能低下を抑制するサービスを明らかにすることができる。
