The creatinine index is a simple parameter that reflects the dietary protein intake (from skeletal muscle) and skeletal muscle mass of a patient. This can help in the assessment of the protein-energy wasting that occurs in long-term hemodialysis patients.
Parameters:
(1) sex
(2) age in years
(3) single-pool Kt/V for urea (dialysis adequacy)
(4) serum creatinine prior to dialysis

creatinine index in mg/kg/day =
= SUM(points for all of the parameters) + 16.21
Interpretation:
• A downward trend in the creatinine index is associated with clinical deterioration.
• A creatinine index less than 22 mg/kg/day is considered reduced
