醫療照護適當性：概念性定義、測量與國際倡議

Appropriateness of medical care: conceptualization, measurement, and international initiative review

醫療照護適當性為醫療品質的面向之一，概念性定義為正確的病人、正確的治療地點、正確的照護提供者、正確的時間，提供或使用正確照護的組合。測量方法包括內隱指標、明確指標及混合指標，國際醫療照護適當性倡議與實踐可分為概念建構期、指標建立期、減少浪費及避免低價值服務期、政策結合期。本文簡要回顧醫療照護適當性之定義、測量及國際倡議經驗，並討論研究與政策發展意涵，供後續學術與政策之應用。

Appropriateness of medical care is a crucial dimension of medical quality. The most common conceptual definition is the provision of the right care for the right patient, the right setting, the right service provider, and the right time. Measurement methods include implicit, explicit, and combined criteria. International initiatives and practices of appropriateness in medical care can be divided into the concept construction period, the indicator establishment period, the waste reduction and low-value care reduction period, and the policy implementation period. This narrative review reports the conceptual definition, measurement methods, and international initiatives of appropriateness of medical care. Implications for future research and policy development are discussed.
