まとめ
この研究は,低所得国および中所得国のワクチンと保健システムに対する信頼を測定するためのワクチン信頼枠組みを開発し,検証した. フレームワークは信頼の不足に対処することで 弾力的なワクチン需要を構築するのに役立ちます.
科学分野:
- 世界保健
- ワクチン学
- 医療システム研究
背景:
- ワクチンの需要には信頼が不可欠ですが,低・中所得国 (LMICs) では明確な定義と検証された測定ツールが欠けています.
- 現存する信頼指標は ワクチン接種率を向上させるのに 関連性や有効性がないことが多いのです
研究 の 目的:
- LMICにおけるワクチンの関連性のある信頼の枠組みと測定ツールを開発し,検証する.
- ワクチンの需要を回復させる 戦略として信頼を活用する
主な方法:
- ナイジェリア,ケニア,パキスタンでの民族学的研究を含む探索的連続混合方法の研究.
- ケニアとパキスタンの介護者を対象とした全国的な調査を通じて,ワクチン信頼枠組みの検証.
- 心理学的性質とワクチン接種行動との関連を評価するために,確認因数分析とロジスティック回帰を用いた分析.
主要な成果:
- ワクチン信頼の枠組みは4つの領域と15の次元から成り立っています
- ケニアとパキスタンの7404人の参加者からの調査データは,信頼がワクチンの行動と意図に影響することを示しました.
- 地元の健康とワクチンのシステムに対する認識に関する定性的な発見と一致する信頼の地域的変動が観察されました.
結論:
- 検証されたワクチン信頼枠組みは,LMICにおける保健システムとワクチン信頼を評価するための文脈に基づいたツールを提供します.
- この枠組みは,予測ツール,援助介入の設計,またはモニタリング研究における測定ツールとして機能することができます.
- 信頼を築くための介入の設計と測定におけるその有用性を評価するためのさらなる研究が進行中です.

Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

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...
