Activity 3D. Calculating a CTP Score PDF Share Learning Objective Performance Indicators Initiate a comprehensive clinical and laboratory evaluation prior to treating a person for HCV infection Obtain the recommended core set of laboratory tests indicated for persons prior to starting HCV treatment Differentiate laboratory testing recommendations in persons with HCV based on cirrhosis status Correctly interpret test results for noninvasive assessment tools used to stage liver fibrosis Recognize the conditions that would lead to a presumptive diagnosis of decompensated cirrhosis Instructions: Read the case history, use the calculator below to determine the CTP score, and then answer the Activity Question.Case HistoryA 49-year-old woman is diagnosed with HCV infection but is lost to follow-up for several years. She is hospitalized 2 years later with abdominal distension and found to have ascites that requires large-volume paracentesis. Subsequently, the ascites responds well to diuretic therapy. She does not have hepatic encephalopathy. Hospital admission laboratory studies show the following: total bilirubin 2.5 mg/dL, serum albumin 2.7 mg/dL, alanine transaminase (ALT) 35 U/L, aspartate aminotransferase (AST) 65 IU/L, and international normalized ratio (INR) 1.9.Child-Turcotte-Pugh (CTP) Calculator ShareUse the Child-Turcotte-Pugh Classification for Severity of Cirrhosis calculator to estimate the cirrhosis severity. Select the applicable Clinical and Lab Criterias, then check the classification at the bottom. PointsClinical and Lab Criteria Encephalopathy None+1 Mild to moderate (grade 1 or 2)+2 Severe (grade 3 or 4)+3 Ascites None+1 Mild to moderate (diuretic responsive)+2 Severe (diuretic refractory)+3 Bilirubin (mg/dL) < 2+1 2-3+2 > 3+3 Albumin (g/dL) > 3.5+1 2.8-3.5+2 < 2.8+3 International normalized ratio < 1.7+1 1.7-2.3+2 > 2.3+3 Child-Turcotte-Pugh Class obtained by adding score for each parameter (total points) Related ActivitiesYou may find more information and a scenario for which you can use this calculator in the following activities from our curriculum:Calculating CTPCalculating a CTP Score This calculator operates entirely from your device.
