307 patients ≥65years who were hospitalized in geriatric wards were included in this prospective analysis. A fifty-item frailty index (FI), a ten-domain+co-morbidity frailty index based on a standardized comprehensive geriatric assessment (FI-CGA), the nine category Clinical Frailty Scale (CFS-9), the CSHA rules-based frailty definition (CSHA-RBFD), and the frailty phenotype (FP) were assessed during the patients' hospital stays.
Among those frailty instruments that were evaluated, the CFS-9 emerged as the most powerful for prediction of one-year mortality.
