SummaryBackground & aimsMalnutrition is common in older persons. However, it is unclear whether malnutrition diagnosed with the Mini Nutritional Assessment (MNA) predicts mortality in older hospitalized patients.MethodsWe prospectively studied the impact of the MNA-short form (MNA-SF) and co-morbidities on long-term mortality in 444 patients (mean age 85.3 ± 6.7; 74.0% women) receiving geriatric inpatient care. In a cross-sectional study we studied the interplay between the MNA, nutritional markers and co-morbidities (using the Cumulative Illness Rating Scale, CIRS).ResultsThe prevalence of malnutrition and “at risk of malnutrition”, defined by MNA-SF, was 25.5 and 50.5% respectively in our prospective study. CIRS scores (HR = 1.09, p < 0.001) and a low BMI (HR = 0.96, p < 0.05), but not the MNA-SF (HR = 0.79 and 0.89 for “at risk” and malnutrition respectively, P = NS), were associated with 4-year mortality. CIRS scores, albumin and other nutritional markers were similar between MNA categories. High CIRS scores and hypoalbuminemia were observed even in patients with normal MNA scores. There was good agreement (>80%) between the MNA-SF and the complete MNA.ConclusionsMalnutrition as diagnosed with the MNA at admission failed to predict long-term mortality in older inpatients, likely due to the overriding impact of co-morbidities and acute disease.
