['Cirrhotic patients undergoing transjugular intrahepatic portosystemic shunt (TIPS) for refractory ascites or recurrent variceal bleeding are at risk for decompensation and death. This study examined whether a new model for end stage liver disease (MELD), which incorporates serum sodium (MELDNa), is a better predictor of death or transplant after TIPS than the original MELD.', "One hundred forty-eight consecutive patients undergoing nonemergent TIPS for refractory ascites or recurrent variceal bleeding from 1997 to 2006 at a single center were evaluated retrospectively. Cox model analysis was performed with death or transplant within 6 months as the end point. The models were compared using the Harrell's C index. Recursive partitioning determined the optimal MELDNa cutoff to maximize the risk:benefit ratio of TIPS.", 'The predictive ability of MELDNa was superior to MELD, particularly in patients with low MELD scores. The C indices (95% confidence interval [CI]) for MELDNa and MELD were 0.65 (95% CI, 0.55-0.71) and 0.58 (95% CI, 0.51-0.67) using a cut-off score of 18, and 0.72 (95% CI, 0.60-0.85) and 0.62 (95% CI, 0.49-0.74) using a cut-off score of 15. Using a MELDNa >15, 22% of patients were reclassified to a higher risk with an event rate of 44% compared with 10% when the score was <or=15.'] Does new model for end stage liver disease improve prognostic capability after transjugular intrahepatic portosystemic shunt?
