Geriatric Health Assessment and Frailty Management

Geriatric health assessment integrates multidimensional evaluation of older adults to identify medical, functional, psychological and social needs. The cornerstone is the comprehensive geriatric assessment (CGA), which systematically reviews comorbidity, cognition, mobility, nutrition and social support to guide tailored interventions. Frailty, a clinical syndrome of diminished reserve and resistance to stressors, arises from cumulative declines across multiple physiological systems. It may be operationalised as a phenotype, characterised by weight loss, exhaustion, weakness, slow walking speed and low activity, or as a frailty index that quantifies the accumulation of deficits. Identification of frailty is crucial for risk stratification, allowing preventive measures such as exercise programmes, nutritional optimisation and medication review. Management strategies address sarcopenia through resistance training and protein supplementation, reduce polypharmacy, target underlying contributors such as inflammation or malnutrition, and mobilise social support. Early detection and a person-centred approach have demonstrated reductions in adverse outcomes, including hospitalisation, functional decline and mortality, underscoring the global imperative for frailty-informed care pathways.

Technical terms

Comprehensive Geriatric Assessment (CGA): A multidimensional evaluation of an older person’s medical, functional, psychosocial and environmental status to inform care planning.

Frailty Phenotype: A clinical construct defining frailty by the presence of three or more specific criteria such as unintentional weight loss, muscle weakness, exhaustion, slow gait speed and low physical activity.

Frailty Index: A quantitative measure reflecting the proportion of accumulated health deficits (symptoms, signs, diseases) in an individual, expressed as a ratio.

Sarcopenia: Progressive loss of skeletal muscle mass and strength associated with ageing, contributing to frailty and physical disability.

Polypharmacy: Concurrent use of multiple medications, which increases the risk of adverse drug events and can exacerbate frailty.
