Predicting outcomes of frail older adults is complex, especially when they become seriously ill.
GAPNA member Margaret Sayers and co-authors tested the measurement properties, especially the predictive validity, of a frailty index based on a comprehensive geriatric assessment (FI-CGA) in an acute care setting in relation to the risk of death, length of stay, and discharge destination.
Results indicated the risk of dying increased with each 0.01 increment in the FI-CGA. People who were discharged home had the lowest admitting mean FI-CGA compared with those who died, or were discharged to nursing home. Likewise, increasing FI-CGA values on admission were significantly associated with a longer length of hospital stay.
The authors concluded frailty, measured by the FI-CGA, was independently associated with a higher risk of death and other adverse outcomes in older people admitted to an acute care hospital.
