Recommendation ID
Nutritional status:- Is there any significant difference in nutritional status between people on the different dialysis treatment modalities?
Any explanatory notes
(if applicable)
Why this is important:- Undernutrition is a frequent finding in people with established renal failure (present in 30–40% of patients) and is associated with reduced survival. Conversely, weight gain, or regain, is common after starting peritoneal dialysis and is associated with a worsening lipid profile. Very high and low serum phosphate concentrations are also associated with poor outcomes. Clinical interventions are currently used to try to correct both abnormal phosphate levels and malnutrition. A rigorous study, using validated methods, is needed to compare the effects of haemodialysis and peritoneal dialysis on markers of nutritional status and phosphate control.
There is no single gold standard measure of nutritional status, so a panel of measurements should be used, reflecting the various aspects of protein–energy malnutrition. These outcome measurements should include subjective global assessment, assessment of dietary intake, anthropometric measures,weight and body mass index, biochemical markers (including phosphate, calcium, serum creatinine and albumin), and estimation of dialysis adequacy and residual renal function.
