Performance of GLIM with different nutrition risk screening tools in predicting 90-day mortality in critically ill adults with acute stroke: A comparison study.

Abstract

Background: The Global Leadership Initiative on Malnutrition (GLIM) proposes a diagnostic process for malnutrition, including initial screening with nutrition screening tools, followed by diagnostic evaluation. This study aimed to compare the performance of GLIM with different nutrition screening tools in predicting 90-day mortality in adults who are critically ill with acute stroke.

Methods: A comparative study was conducted on 308 adults (who critically ill) with acute stroke. Multiple nutrition screening tools were evaluated upon admission. Nutrition status was assessed using GLIM criteria. The predictive performance of GLIM on mortality was analyzed using Cox regression.

Results: The prevalence of malnutrition ranged from 17.86% to 28.25%, depending on the nutrition screening tools used for classification. During 90-day of follow-ups, 112 (36.36%) deaths occurred. GLIM effectively predicted 90-day mortality, with GLIM and the modified Nutritional Risk in the Critically Ill (mNUTRIC) screening demonstrating the best predictive ability [Hazard Ratio: 2.807 (1.816-4.339)].

Conclusion: Malnutrition identified by GLIM with mNUTRIC demonstrates a good ability to predict mortality in critically ill adults with acute stroke. GLIM criteria anticipate mortality and might guide interventions, with important implications for clinical practice and research.
