  1. CRBSI catheter-related blood stream infection
  2. Fit using forwards stepwise selection using all variables listed in Table 1 and forcing age and distance to closest nephrology practice to remain in the model
  3. aSubstances include alcohol, cocaine, ecstasy, intravenous drugs, marijuana, off-prescription drugs, and smoking
  4. Liver disease includes alpha-1 antitrypsin disease of the liver, cirrhosis due to any cause, fatty
  5. bLiver disease if confirmed on liver biopsy (ever), glycogen storage diseases, hemochromatosis, primary biliary cirrhosis, primary sclerosing cholangitis, veno-occlusive liver disease, and Wilson’s disease
