There is a paucity of data for the assessment of frailty in acutely ill hospitalized older adults. We aim to (1) compare the performance of frailty measures [5-item scale of fatigue, resistance, ambulation, illnesses, and loss of weight) (FRAIL), Tilburg Frailty Indicator (TFI), and Clinical Frailty Scale (CFS)] in identifying frailty, using the widely adopted Frailty Index (FI) as "gold standard," and (2) compare their ability to predict negative outcomes among hospitalized older adults. ⋯ FRAIL and CFS are simple frailty measures that may identify older adults at highest risk of adverse outcomes of hospitalization. FRAIL performed better in predicting in-hospital mortality.
