UNOS Region:

This calculator uses a random forest classifier and correctly classifies patients at risk of developing composite renal outcome(CRO) within first year of heart transplantation with an AUC of 70%, sensitivity of 80%, specificity of 46%, negative predictive value of 98%, and positive predictive value of 8%.

*Composite renal outcome (CRO) defined as dependence on chronic dialysis, eGFR < 20 ml/min/1.73 m² or received a kidney transplantation within first year of transplant among adult heart transplant alone recipients.
§Default eGFR value is 10 ml/min/1.73 m² if on dialysis
