Following a recommendation of the Consensus Conference on Transplant Program Quality and Surveillance, SRTR implemented a 3-year rolling cycle to rebuild the statistical models used to derive expected outcomes and evaluate program performance. SRTR developed a standardized model-building process with oversight by the SRTR Technical Advisory Committee, and new models for kidney transplant recipients have been developed. Transplants performed 1/1/2011-6/30/2013 were used to develop the models. The least absolute shrinkage and selection operator (LASSO) procedure was used to determine the optimal set and form of risk predictors to include in the models such that the predictive ability of the models was optimized using 10-fold cross-validation. The discriminatory ability of the models as measured by the C statistic ranged from 0.65 to 0.76 (Table), comparable with the previous models.
Model | C statistic |
---|---|
Adult, deceased donor, graft survival | 0.6576 |
Adult, deceased donor, patient survival | 0.7136 |
Adult, living donor, graft survival | 0.6735 |
Adult, living donor, patient survival | 0.7599 |
