Chapter 32: Functional Assessment of the Older Adult

Functional Assessment of the Older Adult delves into the multidimensional functional assessment of the older adult, a crucial component of geriatric healthcare aimed at distinguishing normal age-related changes from pathological geriatric syndromes. It provides a foundational framework for evaluating an individual's functional status, which encompasses basic Activities of Daily Living (ADLs) assessed by tools like the Katz Index, and more complex Instrumental Activities of Daily Living (IADLs) measured via the Lawton scale. The text also explores Advanced Activities of Daily Living (AADLs) and objective physical performance metrics, prominently featuring the Timed Up and Go (TUG) Test to quantify functional mobility and evaluate fall risk. A significant portion of the chapter focuses on the cognitive and psychological domains, differentiating among dementia, delirium, and depression while highlighting vital screening instruments such as the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), and the Geriatric Depression Scale. Furthermore, the assessment expands into the social domain, evaluating formal and informal support networks alongside the critical identification of caregiver burden and burnout. The educational material thoroughly examines various contexts of care, ranging from Acute Care for Elders (ACE) units and innovative Hospital at Home programs to assisted living, skilled nursing facilities, and continuing-care retirement communities that support the concept of aging in place. To promote the maintenance of independence, the chapter strongly advocates for tailored physical exercise regimens, meticulous environmental hazard assessments to prevent falls, and proactive discussions regarding older-adult driving safety and cessation. It concludes by addressing essential special considerations for the aging patient, including nonpharmacologic sleep interventions, spiritual health evaluations, and adapted communication strategies for interviewing individuals experiencing pain or altered cognition, ensuring a holistic, patient-centered approach to elder care and nursing practice.
