14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Methods Of Healthcare Delivery System

3.9K
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

科学分野:

  • 神経学および老年医学
  • バイオマーカー発見
  • 疫学

背景:

  • 前臨床アルツハイマー病(AD)は、認知機能が正常な個人におけるAD病理のバイオマーカー証拠によって特徴付けられます。
  • 現在の診断方法(PETスキャン、CSF収集)は侵襲的であり、認知機能が正常な集団には標準的ではありません。
  • 血液ベースのバイオマーカー(BBM)は、AD検出のための低侵襲性、スケーラブル、かつ費用対効果の高い代替手段を提供します。

研究 の 目的:

  • 米国、日本、ドイツ、中国における認知機能低下のリスクが最も高い50歳以上の前臨床AD患者の数を推定すること。
  • 血漿p-tau217レベルが前臨床ADの高リスク集団を特定する潜在的な有用性を評価すること。
  • 将来のAD介入のためのヘルスケアインフラストラクチャと予算計画に情報を提供すること。

主な方法:

  • 国別の国勢調査データと、認知症、MCI、アミロイドPET陽性の文献ベースの有病率推定値を利用しました。
  • アミロイド陽性で認知機能が正常な個人における臨床進行率が最も高い血漿p-tau217レベルの上位3分の1と関連付ける最近の発見を適用しました。
  • アミロイドPET陽性の前臨床AD集団の3分の1を考慮して、高リスクの前臨床AD集団を推定しました。

主要な成果:

  • アミロイドPET陽性を基準とした前臨床ADの推定人口(50歳以上):米国(22.0M、18.3%)、日本(11.2M、19.0%)、ドイツ(7.0M、18.5%)、中国(90.7M、17.0%)。
  • 推定高リスク前臨床AD人口(p-tau217の上位3分の1):米国(7.3M、6.1%)、日本(3.7M、6.3%)、ドイツ(2.3M、6.2%)、中国(30.2M、5.7%)。

結論:

  • 前臨床ADを有する相当数の個人は、効率的なスクリーニング方法の必要性を強調しています。
  • 血漿p-tau217などの血液ベースのバイオマーカーは、高リスクの個人を特定するのに役立ち、医療負担を軽減する可能性があります。
  • 経済的影響評価と治療計画のために、前臨床ADにおける血漿p-tau217の有病率に関するさらなる研究が不可欠です。
