Comprehensive Geriatric Assessment and Frailty
Also known as comprehensive geriatric assessment · CGA · geriatric assessment · frailty · frailty phenotype · frailty index · Clinical Frailty Scale · CFS · sarcopenia · EWGSOP2 · Katz index · Lawton IADL scale · Timed Up and Go · MNA-SF · geriatric evaluation and management · GEM
Consultant-physician-depth guide to comprehensive geriatric assessment (CGA) and frailty for FRACP DWE and DCE — the multidimensional interdisciplinary diagnostic process, the four domains (medical, functional, psychological, social), the Katz ADL index, the Lawton IADL scale, the Timed Up and Go test, the Fried frailty phenotype, the Rockwood frailty index, the Clinical Frailty Scale, the EWGSOP2 sarcopenia criteria, the MNA-SF nutrition screen, the 4AT delirium screen, the MoCA and GDS, the CGA delivery models, and the Cochrane meta-analysis evidence for reduced mortality and institutionalisation.

Red flags
- An older person who is functionally declining — falling, losing weight, or losing independence in ADLs — is frail until proven otherwise, and the frailty is a treatable target, not an inevitable consequence of ageing
- Unintentional weight loss of more than 5 percent in 3 months or more than 10 percent in 6 months in an older person is a red flag for frailty, sarcopenia, malignancy, and depression — investigate, do not reassure
- A slow gait speed — under 0.8 metres per second over 4 metres — is a powerful single predictor of frailty, falls, disability, and mortality, and it should be measured in every geriatric assessment
- An older patient who is admitted to hospital and scores Clinical Frailty Scale 5 or above is at high risk of delirium, falls, pressure injuries, functional decline, institutionalisation, and death — the CFS changes the care plan, not just the paperwork
- Sarcopenia is not the same as frailty, but they overlap — low grip strength (under 27 kg in men, under 16 kg in women) plus low muscle mass on DEXA defines probable sarcopenia by EWGSOP2 and demands protein, resistance exercise, and vitamin D
Comprehensive Geriatric Assessment and Frailty
Meet the patient
An 82-year-old woman is admitted after a fall and a fractured wrist. She has fallen twice in six months, her medications number twelve, and her daughter says she has stopped managing her own finances. Her gait is slow and cautious, her grip is weak, and her MoCA is 21. The single number that belongs on her chart within 24 hours is the one that ties it all together: her Clinical Frailty Scale score.[1][3]
Two ideas decide her care, and they decide every frail older patient: CGA works when the team controls the care, and frailty is a treatable target, not an inevitability of age. Hold those two and the instruments and the evidence slot into place.[1]
