BACKGROUND & AIMS: We aimed to develop a simple prognostic model in predicting fulminant liver failure (FLF) patient mortality within 14 days after being listed on the waiting list.
METHOD: A total of 4004 patients with FLF who were listed for liver transplantation were enrolled for model formation (n=2782) and validation (n=1222). Through univariate and multivariate logistic analysis, independent risk factors were selected to develop the logistic regression model and construct a nomogram. Discrimination was evaluated by calculating the area under the receiver operating characteristic (AUROC) and calibration by calibration plot and the Hosmer-Lemeshow test.
RESULTS: Etiology, age, international normalized ratio >2.76, bilirubin >15mg/dL, serum creatinine >1.5mg/dL, ventilator use, ascites, Grade 3-4 hepatoencephalopathy were independent predictors for early mortality of FLF patients on the waiting list. The constructed logistic regression model (FLF-transplant score) demonstrated good calibration with excellent discrimination with an AUROC of 0.8031 (0.7833-0.8228) in training set and 0.785 (0.7541-0.8159) in the validation set. The Hosmer-Lemeshow test demonstrated good fitness between prediction and actual results in both training (P=0.4514) and validation (P=0.1625) sets. The performance of constructed model was superior to MELD score with an AUROC of 0.5761 (0.5418-0.6105) in the validation set (P<0.001). Cirrhotic patients with a MELD score > 40 showed a higher 14-day mortality rate than Status 1A patients with a FLF-transplant score < 200 (P<0.001).
CONCLUSIONS: The model developed here show good discrimination and calibration in predicting on-waiting-list mortality. The allocation policy for the FHF patients should be re-considered based on the FLF-transplant score.
