A frailty index derived from a standardized comprehensive geriatric assessment predicts mortality and aged residential care admission.

Background: Frailty in older adults is a condition characterised by a loss or reduction in physiological reserve resulting in increased clinical vulnerability. However, evidence suggests that frailty may be modifiable, and identifying frail older people could help better target specific health care interventions and services.

Methods: This was a regional longitudinal study to develop a frailty index for older adults living in Canterbury New Zealand.
