As Taiwan rapidly transitions into a super-aged society, the growing prevalence of multimorbidity accompanied by geriatric syndromes among older adults has become a major challenge for clinical practice. Because aging is associated with diminished physiological reserve, even minor stressors may trigger systemic deterioration and functional decline. Consequently, the traditional disease-centered model of care is no longer sufficient to address the complex healthcare needs of this population. This review examines the pivotal role of Nurse Practitioners (NPs) within current integrated geriatric care within current healthcare policies and clinical practice. Early identification of high-risk older adults is achieved through the use of the Clinical Frailty Scale (CFS) and the FIND-NEEDS screening tool, followed by a Comprehensive Geriatric Assessment (CGA) to detect atypical presentations and guide individualized care planning. The article further emphasizes a shift from a diagnosis-oriented to a problem-oriented approach by integrating the 5Ms framework (Mind, Mobility, Medications, Multi-complexity, and Matters Most) with the SMARTER principles to develop dynamic, patient-cen-tered care plans. Eliciting patients’ values and priorities—particularly what matters most to them—serves as the cornerstone of shared decision-making, while continuous monitoring and incremental recommendations help improve treatment adherence. Furthermore, NP-led transitional care facilitates seamless communication and coordination across healthcare settings, ensuring continuity of care from hospital to community and reducing the risk of unplanned readmissions. By integrating comprehen-sive assessment, interdisciplinary communication, care coordination, and longitudinal management, nurse practitioners play a critical role in bringing order to the complexity of caring for older adults with multimorbidity and in delivering high-quality, integrated geriatric care.
