The accuracy of the Geriatric Nutritional Risk Index in detecting frailty and sarcopenia in hospitalized older adults.

Sarcopenia, frailty, and malnutrition coexisted in 26% of our sample. GNRI Score at ≤ 86.73 was 71.9% sensitive and 65.6% specific for detecting frailty and its score at ≤ 89.04 was 64.42% sensitive and 63.53% specific for detecting sarcopenia. GNRI is a simple method, which could be used for sarcopenia, and frailty screening in all elders attending primary care settings where other tools for assessing muscle mass are unavailable.
