愛滋病患／HIV感染者因雞尾酒療法的成功治療已成為慢性病，然而治療成功需仰賴幾近完美的服藥信守（adherence），因此服藥信守是愛滋慢性病程中十分重要照護議題。本文以Walker及Avant的概念分析步驟進行愛滋病患／HIV感染者服藥信守的概念分析，由文獻查證中歸納分析出信守三個型態的定義屬性：行動、態度、關係，並由案例分析加以確認概念屬性的範圍。藉由信守概念的前置與促進因素和結果的分析，形成信守概念的架構，以及舉出信守的實證指標與測量工具，均有助於日後發展服藥信守概念相關的護理理論以及更具效度的測量工具，並可運用於提升服藥信守介入措施之相關研究與護理實務。

Due to the success of highly activity antiretroviral therapy, the AIDS/HIV disease has become a chronic disease. However, the success in treatment depends on perfect medicine adherence. Therefore, adherence to medical regiment is an important issue in AIDS/HIV nursing care process. The concept analysis had emphasized in this article.
