Protein-energy wasting (PEW) is the chronic kidney disease (CKD)-specific diagnosis encompassing malnutrition. PEW is associated with adverse outcomes, including those receiving peritoneal dialysis (PD). Identifying PEW requires accurate methods to improve diagnosis. The Global Leadership Initiative on Malnutrition (GLIM) criteria is focused on validating a global consensus for malnutrition diagnosis in adults in clinical settings. While the GLIM criteria has been extensively studied in other clinical populations, there is limited evidence about the agreement with PEW in the PD setting.
