Aim: To measure the ability to predict 6-month mortality of several different instruments for evaluating nutrition, and to compare agreement between results obtained with these different instruments. %26lt;br%26gt;Methods: Prospective, multi-centre cohort study, including subjects aged 75 years or older, admitted to hospital through the emergency room. The predictive capacity of the different nutrition instruments (namely: Mini Nutritional Assessment (MNA), Geriatric Nutritional Risk Index (GNRI), body mass index (BMI) and albuminemia) were tested using a Cox model after adjustment for socio-demographic and clinical variables. Agreement between these four instruments was assessed by calculating Cohen%26apos;s Kappa coefficient. %26lt;br%26gt;Results: In total, 1306 subjects were included in the cohort, average age 85 +/- 6 years. The crude death rate at 6 months was 24.4%. Prevalence of malnutrition varied from 24 to 59%. All the nutrition instruments evaluated were significantly related to survival; the strongest associations with mortality were observed with GNRI (hazard ratio [HR] = 1.65; 95% CI = 1.31-2.06) and MNA (HR = 1.64; 95% CI = 1.27-2.03). Agreement between indicators was moderate to poor. %26lt;br%26gt;Conclusion: The GNRI and the MNA appear to be the most useful tools for detecting malnutrition in elderly patients admitted via the emergency room.
