Question 1

What is the Child-Pugh score?

Accepted Answer

The Child-Pugh score (also called Child-Turcotte-Pugh score) is a clinical scoring system used to assess the severity of chronic liver disease, particularly cirrhosis. It uses five parameters: total bilirubin, serum albumin, INR (or PT), presence of ascites, and degree of hepatic encephalopathy. Each parameter is scored 1-3 points, with total scores ranging from 5-15 points. The score classifies patients into Class A (5-6 points), Class B (7-9 points), or Class C (10-15 points).

Question 2

How do you calculate Child-Pugh score?

Accepted Answer

To calculate Child-Pugh score, assign points (1-3) for each of five parameters: Bilirubin (<2=1pt, 2-3=2pts, >3=3pts), Albumin (>3.5=1pt, 2.8-3.5=2pts, <2.8=3pts), INR (<1.7=1pt, 1.7-2.3=2pts, >2.3=3pts), Ascites (none=1pt, mild=2pts, moderate-severe=3pts), and Encephalopathy (none=1pt, grade 1-2=2pts, grade 3-4=3pts). Sum the points to get total score. Score 5-6=Class A, 7-9=Class B, 10-15=Class C.

Question 3

What does Child-Pugh Class A, B, and C mean?

Accepted Answer

Child-Pugh Class A (5-6 points) indicates well-compensated cirrhosis with 1-year survival of 95-100% and 2-year survival of 85-90%. Class B (7-9 points) represents significant functional compromise with 1-year survival of 80-85% and 2-year survival of 55-60%. Class C (10-15 points) indicates decompensated cirrhosis with poor prognosis: 1-year survival of 45-50% and 2-year survival of 35-40%. The classification guides treatment decisions and transplant evaluation.

Question 4

What is a good Child-Pugh score?

Accepted Answer

A good Child-Pugh score is 5-6 points (Class A), indicating well-compensated cirrhosis. These patients have the best prognosis with excellent survival rates and low surgical risk (10% operative mortality). Patients can often be managed medically with regular monitoring. Scores of 7-9 (Class B) indicate moderate disease requiring close monitoring and possible transplant evaluation. Scores of 10-15 (Class C) represent severe disease requiring urgent transplant evaluation.

Question 5

How does Child-Pugh score predict survival?

Accepted Answer

Child-Pugh score correlates strongly with survival in cirrhosis. Class A patients have 1-year survival of 95-100% and 2-year survival of 85-90%. Class B patients have 1-year survival of 80-85% and 2-year survival of 55-60%. Class C patients have significantly reduced survival: 1-year survival of 45-50% and 2-year survival of 35-40%. The score helps predict complications, guide transplant timing, and inform patient discussions about prognosis.

Question 6

When is Child-Pugh score used?

Accepted Answer

Child-Pugh score is used for: assessing cirrhosis severity and prognosis, stratifying surgical risk in liver disease patients, guiding liver transplant evaluation and priority, predicting survival in chronic liver disease, determining treatment intensity and monitoring frequency, evaluating risk for variceal bleeding and other complications, and making decisions about invasive procedures. It's widely used in hepatology, gastroenterology, and critical care medicine.

Question 7

What is the difference between Child-Pugh and MELD score?

Accepted Answer

Child-Pugh (5-15 point scale) uses five clinical and lab parameters including subjective assessments (ascites, encephalopathy). MELD score (6-40 scale) uses only three objective lab values: bilirubin, creatinine, and INR. MELD is preferred for liver transplant allocation because it's more objective and better predicts short-term mortality. Child-Pugh remains useful for general cirrhosis classification, surgical risk assessment, and clinical decision-making. Many centers use both scores complementarily.

Question 8

Can Child-Pugh score improve?

Accepted Answer

Yes, Child-Pugh score can improve with effective treatment of the underlying liver disease and its complications. Treatment of hepatitis C can reverse fibrosis and improve scores. Alcohol cessation in alcoholic cirrhosis improves outcomes. Managing ascites with diuretics, treating encephalopathy with lactulose, and improving nutrition can reduce point values. However, advanced cirrhosis (Class C) rarely reverses completely. Early intervention in Class A or B offers the best chance for improvement.

Question 9

What are the limitations of Child-Pugh score?

Accepted Answer

Limitations include: subjective assessment of ascites and encephalopathy (inter-observer variability), ceiling effect (maximum 15 points doesn't stratify very sick patients), not validated for acute liver failure, less accurate for short-term mortality prediction than MELD, doesn't include renal function (important prognostic factor), and may not reflect disease severity in some conditions. Despite limitations, it remains widely used and clinically valuable for chronic liver disease assessment.

Question 10

How accurate is this Child-Pugh calculator?

Accepted Answer

This calculator uses the standard Child-Pugh scoring system with validated cutoff values and survival estimates from multiple studies. The calculation is mathematically precise. However, accuracy depends on correct input of clinical parameters. Subjective parameters (ascites severity, encephalopathy grade) require clinical judgment. Survival estimates are population averages and individual outcomes vary. Use this calculator as a clinical tool alongside comprehensive patient assessment and medical judgment.
