台灣已邁入超高齡社會，許多高齡者同時面臨多重共病、多重用藥、功能衰退以及照護需求複雜化等問題。以單一疾病為導向的傳統照護模式已難以回應此一趨勢所衍生的複雜照護需求。在此背景下，整合照護模式逐漸受到重視，其強調醫療、護理、復健與社會資源的連結，並以全人、連續性與功能導向的照護理念為核心。專科護理師（Nurse Practitioner, NP）在此模式中扮演關鍵角色，其進階評估能力、跨疾病整合之臨床判斷、跨專業協作、藥物管理與照護轉銜規劃皆是提升高齡照護品質的核心要素。本文旨在探討NP 在高齡整合照護模式中的角色定位與功能，並進一步分析其於多重共病情境下的臨床決策實務。透過文獻回顧與案例討論，本文說明 NP 如何在複雜臨床情境中進行風險評估、優先順序設定、照護目標協商與跨團隊協作，以達成全人、連續且整合的照護。亦強調 NP 在高齡整合照護中的角色價值，以回應超高齡社會的臨床挑戰。

Traditional disease-centered models are no longer sufficient to address the multifaceted challenges associated with this population. Consequently, integrated care has emerged as a preferred approach, emphasizing the coordination of medical, nursing, rehabilitation, and social services while promoting person-cen-tered, continuous, and function-oriented care. Within this model, Nurse Practitioners (NPs) play a pivotal role in optimizing care for older adults with multimorbidity. Their advanced clinical assess-ment skills, ability to integrate clinical information across multiple chronic conditions, expertise in medication management, leadership in interprofessional collaboration, and coordination of care transi-tions are fundamental to improving the quality and continuity of geriatric care. This article examines the roles and functions of NPs within integrated geriatric care and further discusses their clinical decision-making strategies for managing older adults with multimorbidity. Drawing on the current lit-erature and case-based discussions, the article illustrates how NPs perform comprehensive risk assess-ments, prioritize competing clinical problems, facilitate shared decision-making through goal setting, and coordinate multidisciplinary care in complex clinical situations. These approaches support the delivery of holistic, continuous, and integrated care while addressing patients’ functional goals and individual healthcare priorities. Overall, this article highlights the indispensable role of nurse practi-tioners in integrated geriatric care and demonstrates how their advanced clinical expertise and care coordination capabilities contribute to meeting the growing healthcare demands of an aging society.Taiwan has entered a super-aged society, in which a growing number of older adults experience multi-
