MELD, MELD 3.0, versus Child score to predict mortality after acute variceal hemorrhage: A multicenter US cohort.

ABSTRACT

BACKGROUND: Acute variceal hemorrhage is a major decompensating event in patients with cirrhosis and is associated with high 6-week mortality risk. Many prognostic models based on clinical and laboratory parameters have been developed to risk stratify patients on index bleeding presentation, including those based on the Model for End-Stage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP). However, consensus on model performance remains unclear. METHODS: Using a large US multicenter cohort of hospitalized patients with cirrhosis who presented with acute variceal hemorrhage, this study evaluates, recalibrates, and compares liver severity index-based models, including the more recent MELD 3.0 model, to investigate their predictive performance on 6-week mortality. Models were also recalibrated and externally validated using additional external centers. RESULTS: All recalibrated MELD-based and CTP-based models had excellent discrimination to identify patients at higher risk for 6-week mortality on initial presentation. The recalibrated CTP score model maintained the best calibration and performance within the validation cohort. Patients with low CTP scores (Class A, score 5-6) were strongly associated with < 5% mortality, while high CTP score (Class C, score > 9) were associated with > 20% mortality. CONCLUSION: Use of liver severity index-based models accurately predict 6-week mortality risk for patients admitted to the hospital with acute variceal hemorrhage and supports the utilization of these models in future clinical trials as well as their use in clinical practice.
