Meld score long term prognosis5/8/2023 The Model for End-stage Liver Disease (MELD) 8 does not include encephalopathy and ascites as factors contributing to the probability of being transplanted. SHEILA JOWSEY, TERRY SCHNEEKLOTH, in Transplantation of the Liver (Second Edition), 2005 Adapting to the Waiting Period Status 3 (MELD score <24) includes patients with liver disease that is too early for cadaveric transplantation but may be a suitable live donor transplantation candidate. Status 2b (MELD score 24–29) includes patients with end-stage liver disease, severely ill, but not requiring hospitalization. Status 2a (MELD score >29) includes patients with end-stage liver disease, severely ill, and potentially hospitalized. Status 1 includes patients with acute liver failure/disease with an estimated survival of less than 7 days (highest priority for liver transplantation). MELD is calculated using bilirubin, international normalized ratio, and creatinine (the MELD calculator can be accessed at There are four listing status categories for patients with liver disease: ▪ It is a better predictor of perioperative mortality than the Child's scoring system and therefore has replaced it. The MELD score is an objective model that predicts a patient's 90-day mortality while waiting for a liver transplant. The Model for End-stage Liver Disease (MELD) is a scoring system for prioritizing patients for liver transplantation. Another model called Albumin-Bilirubin (ALBI) score was introduced in February 2015 and uses serum albumin and bilirubin levels to assess liver function ( Johnson et al., 2015). In 2006, the MELD score was updated to include serum sodium levels and referred to as MELD-Na ( Biggins et al., 2006). To overcome this problem, the CP score was replaced by the MELD score in 2002 ( Freeman et al., 2002). Hence, there was a good chance that a person that had the greatest need for a liver transplant might not receive it because they were added to the list at a later time. Within category 3 which had the sickest patients, priority was given to patients who had been on the list the longest. CP score is categorical and classified patients based on their liver function into status 1, 2A, 2B and 3. Prior to 2002, the United Network for Organ Sharing which administers the national Organ Procurement and Transplantation Network, used Child-Pugh score to determine which patient qualified to receive an available donor liver. The risk score in this method was calculated from 4 prognostic values-bilirubin level, creatinine level, International Normalized Ratio (INR), derived from prothrombin time and cause of cirrhosis. MELD was introduced in 2000 to predict survival in patients undergoing transjugular intrahepatic portosystemic shunt procedure for portal hypertension ( Malinchoc et al., 2000).
