The Model for End-Stage Liver Disease (MELD) score has reduced predictive ability in patients with cirrhosis and MELD scores ≤ 20. We aimed to assess whether a 5-stage clinical model could identify liver transplantation (LT) candidates with low MELD scores who are at increased risk for death. We conducted a case-control study of subjects with cirrhosis and MELD scores ≤ 20 who were awaiting LT at a single academic medical center between February 2002 and May 2011. Conditional logistic regression was used to evaluate the risk of liver-related death according to the cirrhosis stage. We identified 41 case subjects who died from liver-related causes with MELD scores ≤ 20 within 90 days of death while they were waiting for LT. The cases were matched with up to 3 controls (66 controls in all) on the basis of the listing year, age, sex, liver disease etiology, presence of hepatocellular carcinoma, and MELD score. The cirrhosis stage was assessed for all subjects: (1) no varices or ascites, (2) varices, (3) variceal bleeding, (4) ascites, and (5) ascites and variceal bleeding. The MELD scores were similar for cases and controls. Clinical states contributing to death in cases were: sepsis 49%, spontaneous bacterial peritonitis 15%, variceal bleeding 24%, and hepatorenal syndrome 22%. In a univariate analysis, variceal bleeding [odds ratio (OR) = 5.6, P = 0.003], albumin (OR = 0.5, P = 0.041), an increasing cirrhosis stage (P = 0.003), reaching cirrhosis stage 2, 3, or 4 versus lower stages (OR = 3.6, P = 0.048; OR = 7.4, P < 0.001; and OR = 4.1, P = 0.008), a sodium level < 135 mmol/L (OR = 3.4, P = 0.006), and hepatic encephalopathy (OR = 2.3, P = 0.082) were associated with liver-related death. In a multivariate model including the cirrhosis stage, albumin, sodium, and hepatic encephalopathy, an increasing cirrhosis stage (P = 0.010) was independently associated with liver-related death. In conclusion, assessing the cirrhosis stage in patients with low MELD scores awaiting LT may help to select candidates for more aggressive monitoring or for living or extended criteria donation.
