To conduct a pragmatic randomized clinical trial in which the researchers will determine the mortality impact of a protocol whereby all hemodialysis patients receive an oral, protein-based nutritional supplement during the dialysis procedure as compared to the existing nutritional protocol whereby only hemodialysis patients with serum albumin below 3.5 g/dL and incident hemodialysis patients during the first months of care receive an oral, intradialytic protein-based nutritional supplement during the dialysis procedure.
