Complementarity of nutritional screening tools to GLIM criteria on malnutrition diagnosis in hospitalised patients: A secondary analysis of a longitudinal study.

Background & Aims: The Global Leadership Initiative on Malnutrition (GLIM) proposed a two-step approach for the malnutrition diagnosis: screening to identify "at risk" patients by any validated nutritional screening tool (NST), followed by a detailed nutritional assessment for diagnosis and grading the severity of malnutrition. Since there are several validated NST, this study aimed to evaluate the complementarity of five NST to GLIM criteria for malnutrition diagnosis in a sample of hospitalized patients.

Methods: A secondary analysis of a longitudinal study.
