Geriatric Assessment and Evaluation
Geriatric assessment and evaluation is the structured, multidimensional appraisal of an older adult's medical, functional, cognitive, psychological, and social status. Rather than focusing on a single organ system, it characterises the whole person to identify problems, capacities, and care needs that a conventional disease-oriented evaluation would miss.
Definition
Geriatric assessment is a systematic, multidimensional and usually interdisciplinary process that evaluates the medical, functional, cognitive, psychological, and social domains of an older person to generate an integrated picture of health status and care needs.
Scope
This area orients the reader to how older adults are assessed across several domains: overall multidimensional (comprehensive) evaluation, functional status and activities of daily living, frailty, cognition and mental status, and social and environmental circumstances. It frames assessment as a methodological and conceptual field within geriatric medicine and not as treatment guidance.
Sub-topics
Core questions
- What domains beyond disease diagnosis determine an older adult's health and care needs?
- How does multidimensional assessment differ from standard single-system clinical evaluation?
- Why are function, frailty, cognition, and social context treated as distinct but interacting assessment domains?
Key concepts
- Multidimensional assessment
- Interdisciplinary evaluation
- Functional status
- Frailty
- Cognitive and mental status
- Social and environmental context
- Domain integration into a care picture
Mechanisms
Geriatric assessment works by decomposing an older person's health into complementary domains and then recombining the findings into an integrated profile. Each domain is appraised with validated instruments and clinical observation, and the domains interact: impaired cognition can degrade functional independence, frailty amplifies vulnerability to stressors, and social or environmental factors shape whether assessed needs can be met. Comprehensive geriatric assessment formalises this logic as a coordinated, often interdisciplinary process whose value over usual care has been examined in controlled trials and meta-analyses.
Clinical relevance
Multidimensional assessment underpins how geriatric medicine describes and stratifies older patients, and meta-analyses of comprehensive geriatric assessment have examined its association with outcomes such as independent living. The area describes how older adults are characterised and how evidence on assessment is generated; it is reference-educational and is not a basis for individual diagnostic or treatment decisions.
Epidemiology
Population ageing has made multidimensional assessment increasingly central to the care of older adults, who frequently present with multimorbidity, functional decline, and frailty that no single diagnosis captures. Frailty in particular is common in later life and rises with age, motivating assessment frameworks that look beyond discrete diseases.
History
Structured assessment of older patients grew out of mid-twentieth-century British geriatric medicine and was consolidated as comprehensive geriatric assessment in the later twentieth century. Stuck and colleagues' 1993 meta-analysis brought the approach to wide attention by pooling controlled trials, and subsequent syntheses such as Ellis and colleagues (2011) extended the evidence to hospitalised older adults, while the parallel maturation of frailty science added a further organising concept to the field.

Frequently asked questions
- How does geriatric assessment differ from a standard medical evaluation?
- A standard evaluation centres on diagnosing disease in specific organ systems, whereas geriatric assessment is explicitly multidimensional, appraising medical, functional, cognitive, psychological, and social domains together to build an integrated picture of the whole person.
- What are the main domains of geriatric assessment?
- Commonly recognised domains include overall multidimensional evaluation, functional status and activities of daily living, frailty, cognition and mental status, and social and environmental circumstances, each of which is covered as a topic under this area.
