まとめ
世界の認知症ケアコストは劇的に変化しており、シリアや日本のような一部の国では経済を上回る支出の伸びが見られます。これは、高齢化が進む中で、慎重な医療政策立案の必要性を浮き彫りにしています。
科学分野:
- 老年医学と公衆衛生、医療経済学、グローバルヘルス政策
背景:
- 65歳以上の世界の人口は2030年までに10億人を超えると予測されています。認知症関連支出は2050年までに1兆6000億ドルに達すると予測されており、政策立案のためにGDPに対する相対的な変化を追跡する必要があります。
研究 の 目的:
- 2000年から2019年までの認知症ケア支出と費用の世界的な傾向を分析すること。国の経済成長(GDP)と認知症関連支出の変化との関係を評価すること。
主な方法:
- 認知症関連支出、GDP、および医療支出に関するIHME、世界銀行、WHOのデータを利用しました。195カ国のケア率、単価、および関連支出の相対的な変化を計算しました。多くの国について、支出弾力性と認知症関連支出の相対変化率(DERCR)を決定しました。
主要な成果:
- 20年以上にわたり、認知症ケアの率と費用には著しい世界的なばらつきが観察されました。シリアと日本は、経済全体の拡大を上回る認知症関連支出の伸びを示しました。ミャンマーにおける認知症の地域ベースケアの増加が最大であり、日本におけるナーシングホームベースケアの単価弾力性が最も高いなど、国別の顕著な変化がありました。
結論:
- 2000年から2019年の間に、認知症ケアの利用と支出において、世界的に著しい相対的な変化がありました。認知症ケア支出は、特にシリアと日本のような特定の国々において、経済成長よりも急速に増加しています。認知症ケア費用の増加における国別のパターンを特定するためには、さらなる研究が必要です。
