Abstract: Background: The population of adults aged 80 years and older is heterogenous with some being robust and others having a higher risk for adverse events. This study compares the predictive value of two tools used to identify older adults who are at higher risk for adverse outcomes: frailty phenotype according to Fried and a standardized physical performance test. Methods: The BELFRAIL population-based cohort of 567 community-dwelling adults aged 80 years and older living in Belgium. Fried frailty phenotype and physical performance test (gait, chair stand, standing balance tests and putting on and off a cardigan). The predictive value of the two tools in predicting mortality (up to 5.1 ± 0.25 years), hospitalization (3.0 ± 0.25 years) and decline in activities of daily living (after 1.7 ± 0.21 years) was compared using reclassification statistics and decision curve analysis. Results: Frail participants according to Fried phenotype and those in the lowest quartile of the physical performance test score had higher risk for mortality and hospitalization. Harrell C and area under operator curve were similar (< 0.70). Reclassification statistics and net benefit in decision curve analysis showed no significant difference between the two tools in identifying higher risk for mortality, hospitalization and functional decline. Conclusion: In a cohort of community-dwelling adults 80 years and older a standardized physical performance test was as good as the Fried frailty phenotype in identifying higher risk for adverse outcomes.
