The Child-Turcotte-Pugh score can be modified by inclusion of serum creatinine as a measure of renal function.
Parameter based on admission data:
(1) Child-Turcotte-Pugh score (from 5 to 15)
(2) serum creatinine in mg/dL
Serum Creatinine
Points
< 1.3 mg/dL
0
1.3 to 1.8 mg/dL
2
> 1.8 mg/dL
4
modified CTP score =
= (CTP score) + (points for serum creatinine)
Interpretation:
• minimum score: 5
• maximum score: 19
• The higher the score the worse the prognosis.
Performance:
• The modified score has areas under the ROC curve close to those shown for MELD score for 3 and 6 month survivals.
Subsequently Giannini et al reported a slightly different point assignment for the serum creatinine.
