Abstract

Globally, rapid population aging—particularly in Korea—has extended life expectancy but not proportionally extended healthy life expectancy, resulting in longer periods of illness or disability and a higher demand for complex medical and social care. Therefore, prolonging healthy life and improving health-related quality of life have become primary objectives in geriatric medicine and rehabilitation. Geriatric rehabilitation is a critical intervention aimed at optimizing the functioning of older adults and pre-morbidly frail individuals who have lost independence due to acute illness or injury. For many older patients, the goal shifts from complete recovery to achieving a new equilibrium, maximizing autonomy despite greater dependency. Geriatric rehabilitation also targets key geriatric syndromes such as frailty, recognizing it as a dynamic and potentially reversible state that provides a crucial “time window” for intervention. This review summarizes the core principles and structural elements essential for geriatric rehabilitation, emphasizing the implementation challenges within the Korean healthcare system. Unlike the European consensus, which supports structured inpatient and outpatient services with seamless transitions of care guided by Comprehensive Geriatric Assessment, the Korean healthcare system remains fragmented and heavily centered on acute hospitals. This highlights the urgent need for a systematic model to integrate care facilities and strengthen interprofessional collaboration to support community-based “aging in place.” Effective geriatric rehabilitation requires multidisciplinary teams and multifaceted approaches to optimize quality of life, social participation, and independent living. Despite its importance, substantial awareness gaps and policy barriers persist, underscoring an urgent call to action.
