The National Kidney Foundation’s Kidney Disease Outcomes Quality Initiative (KDOQI) issued a clinical practice guideline for Nutrition in Chronic Renal Failure, as well as a 2008 revision of recommendations for Nutrition in Children with CKD. For adult patients on maintenance dialysis, the KDOQI guidelines recommend routine assessment of the following nutritional parameters:

  • Predialysis or stabilized serum albumin: Monthly
  • Percentage of usual postdialysis (hemodialysis) or postdrain (peritoneal dialysis) body weight: Monthly
  • Percentage of standard (National Health and Examination Survey II [NHANES II]) body weight: Every 4 months
  • Subjective global assessment: Every 6 months
  • Dietary interview and/or diet diary: Every 6 months
  • Protein Equivalent of Total Nitrogen Appearance normalized to body weight (nPNA): Monthly with hemodialysis; every 3-4 months with peritoneal dialysis
