    Abstract:
    Issues in the selection and timing of liver transplantation for primary sclerosing cholangitis (PSC) remain controversial. Although the Child-Pugh classification (CP) score and Mayo PSC model have similar abilities to estimate pretransplantation survival, a comparison of these 2 scores in predicting survival after liver transplantation has not been conducted. The aim of this study is to compare the Mayo PSC model and CP score in predicting patient survival and related economic outcomes after liver transplantation. Data from 128 patients with PSC, identified from the NIDDK database, were used to calculate patient-specific Mayo PSC and CP scores before transplantation. Levels reflecting a poor outcome were defined a priori. Receiver operating characteristic (ROC) curves and regression methods (Cox proportional hazards and linear regression models) were used to assess the relationship between these 2 scores and 5 post liver transplantation outcome measures. CP score was found to be a significantly (P <.05) better predictor of death 4 months or less after liver transplantation than: (a) length of hospital stay >21 days (or death before discharge) and (b) resource utilization >200,000 units (measured by area under the ROC curve). The Cox model identified statistically significant (P <.05) associations between CP score and each outcome after adjusting for the Mayo PSC risk score. Similar results were not observed for the Mayo PSC model when adjusted for CP score. Among patients with PSC undergoing liver transplantation, CP score was a better overall predictor of both survival and economic resource utilization compared with the Mayo PSC model.
