The goal of this observational study is to investigate how the GLIM criteria* for the diagnosis of malnutrition should be operationalized in patients with chronic kidney disease (CKD) treated with hemodialysis. The main questions it aims to answer are:

• How can malnutrition be defined when applying different combinations and operationalization strategies of the GLIM criteria?

• How can information from other nutrition assessment tools be used in the operationalization of GLIM?

• Which combinations and operationalization strategies of the GLIM criteria can best predict deterioration in quality of life, muscle strength, and increased mortality? This is an observational study on patients with CKD in hemodialysis. Variables are extracted from the Swedish renal registry, SNR and medical records at two hemodialysis units at one university hospital in Sweden. Data collection started in the fall of 2024, and are collected during two timepoints (baseline and follow-up) when wanted variables for this study are routinely measured at the units. Data on 2-year overall survival are also collected.
