Model for end-stage liver disease-sodium underestimates 90-day mortality risk in patients with acute-on-chronic liver failure.
It is unclear whether the model for end-stage liver disease-sodium (MELD-Na) score captures the clinical severity of acute-on-chronic liver failure (ACLF). We compared observed 90-day mortality in patients with ACLF with expected mortality based on the calculated MELD-Na and examined the consequences of underestimating clinical severity. ⋯ Acute-on-chronic liver failure (ACLF) is a condition marked by multiple organ failures in patients with cirrhosis and is associated with a high risk of death. Liver transplantation may be the only curative treatment for these patients. A score called model for end-stage liver disease-sodium (MELD-Na) helps guide donor liver allocation for transplantation in the United States. The higher the MELD-Na score in a patient, the more likely that a patient receives a liver transplant. Our study data showed that MELD-Na score underestimates the risk of dying at 90 days in patients with ACLF. Thus, physicians need to start liver transplant evaluation early instead of waiting for a high MELD-Na number.
