EBPG Guideline on Nutrition

Nutritional status should be assessed at the start of haemodialysis (Opinion). Protein–energy malnutrition should be avoided in maintenance haemodialysis because of poor patient outcome (Evidence III). In absence of malnutrition, nutritional status should be monitored every 6 months in patients 50 years of age, and patients undergoing maintenance dialysis for more than 5 years, nutritional status should be monitored every 3 months (Opinion). Malnutrition is considered to be one of the late complications of chronic renal failure. A sub-analysis of the Modification of Diet in Renal Disease (MDRD) study, however, demonstrated that progressive renal insufficiency was associated with a spontaneous decline in protein intake. Predialysis patients appeared to have a spontaneous protein intake of 50 years every 3 and dialysis years, every 6 years every 3 as to patients and patients should be assessed and at for and be to as Malnutrition should be by a number of assessment assessment mass index global assessment albumin and serum haemodialysis patient should have to a (Opinion). haemodialysis patients should a and in the and should be on medical and (Opinion). haemodialysis patients should be and 1 after haemodialysis has (Opinion). haemodialysis patients should be and more (Opinion). intake should be during a of 3 and should a dialysis and a (Evidence level III). of intake be by to intake of patients from to 3 and the of a is to and as to intake, and of a set of the nutritional status of patients on Data from and a of should be with as be subjective and Patients may their intake is poor their intake is of in be by a a patient as and during the is a that a of and may be in the in patients on It of which It is a for more and on and patients may intake. intake during the may be for the from is to a and may a intake daily may as patients less and several of may more to protein and intake.
