Validating the prognostic value of Freiburg index of posttransjugular intrahepatic portosystemic shunt survival score and classic scores in Chinese patients with implantation of transjugular intrahepatic portosystemic shunt

Background and aims 

It is important and challenging to evaluate the survival of cirrhotic patients undergoing transjugular intrahepatic portosystemic shunt (TIPS). We aimed to validate the Freiburg index of post-TIPS survival (FIPS) score and classic scores for predicting mortality in Chinese patients after TIPS creation.

Methods 

A total of 709 consecutive patients with cirrhosis from December 2011 to July 2018 who underwent TIPS placement were retrospectively reviewed. The prognostic value of the FIPS score, the model for end-stage liver disease (MELD) score, Child-Pugh score and Chronic Liver Failure Consortium Acute Decompensation score was validated with the receiver operating characteristic (ROC) curve and DeLong et al. test.

Results 

The MELD-Na score was superior to the FIPS score in predicting 1-month mortality [AUROC, 0.727 (0.692–0.759) vs. 0.588 (0.551–0.625); P = 0.048]. The MELD and MELD-Na scores were significant superior to the FIPS score in predicting 3-month mortality [AUROC, 0.730 (0.696–0.762) vs. 0.598 (0.561–0.634); P = 0.044 and 0.740 (0.706–0.772) vs. 0.598 (0.561–0.634); P = 0.028]. Subgroup analyses revealed that Child-Pugh score was better than FIPS score in predicting 3-month mortality [AUROC, 0.797 (0.745–0.843) vs. 0.578 (0.517–0.637); P = 0.049] in nonviral cirrhosis group.

Conclusion 

Classic scores still had good risk stratification and predictive ability of post-TIPS mortality. The FIPS score was not superior to the classic scores in the current Chinese cohort. The MELD and MELD-Na scores were significantly superior to the FIPS score in predicting 3-month mortality.
