Development of a novel frailty index to predict mortality in patients with end-stage liver disease.

ABSTRACT: Cirrhosis is characterized by muscle wasting, malnutrition, and functional decline that confer excess mortality not well quantified by the Model for End-Stage Liver Disease (MELD) Sodium (MELDNa) score. We aimed to develop a frailty index to capture these extrahepatic complications of cirrhosis and enhance mortality prediction in patients with cirrhosis. Consecutive outpatients listed for liver transplantation at a single transplant center without MELD exceptions were assessed with candidate frailty measures. Best subset selection analyses with Cox regression identified subsets of frailty measures that predicted waitlist mortality (=death or delisting because of sickness). We selected the frailty index by balancing statistical accuracy with clinical utility. The net reclassification index
