Moreau-Gaudrey et al reported a simple score for evaluating the nutritional status of a patient undergoing maintenance hemodialysis. The authors are from multiple institutions in France.
Patient selection: maintenance hemodialysis
Parameters:
(1) serum albumin in g/dL
(2) body mass index (BMI) in kg per square meter (using postdialysis body weight)
(3) predialysisserum creatinine to body surface area ratio (µmol/L per square meter)
(4) normalized protein nitrogen appearance (nPNA) in g per kg per day (a measure of protein intake)

total score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: 0
• maximum score: 4
• The higher the score the better the overall survival.
• A patient with a low score is likely to benefit from nutritional support.
