Abstract
This study investigated a 3-step procedure of nutritional risk screening, evaluation, and Global Leadership Initiative on Malnutrition (GLIM) diagnosis for Chinese elderly inpatients. Nutritional risk screening was performed as the first step using the Nutritional Risk Screening 2002 (NRS2002). Nutritional status evaluation was performed as the second step using the Mini-Nutritional Assessment Short Form (MNA-SF). Malnutrition diagnosis was performed as the third step using the GLIM criteria. The consistency of these tools and the validity of the GLIM criteria were proven. Fewer patients met the GLIM criteria compared with the NRS2002. Good correlations between malnutrition and frailty or sarcopenia were discovered.
