Table 1 Formulae for calculating Kidney Donor Profile Index and expected post-transplant survival
KDPI
KDPI = exp (-0.0194 × I[age < 18 year] × [age - 18 year] + 0.0128 × [age - 40 year] + 0.0107 × I[age > 50 year] + 0.179 × I[race = African American] + 0.126 × I[hypertensive] + 0.130 × I[diabetic] + 0.220 × [SCr - 1 mg/dL] - 0.209 × I[SCr 1.5 mg/dL] × [SCr - 1.5 mg/dL] + 0.0881 × I[cause of death = CVA] - 0.0464 × [{height - 170 cm}/10] - 0.0199 × I[weight < 80 kg] × [{weight - 80 kg}/5] + 0.133 × I[donation after cardiac death] + 0.240 × I[hepatitis C] - 0.0766, where I is equal to 1 if the condition is true and I is equal to 0 if the condition is false
EPTS
EPTS score = 0.047 × MAX (age - 25. 0) - 0.015 × Diabetes × MAX (Age - 25.0) + 0.398 × Prior Organ Transplant - 0.237 × Diabetes × Prior Organ Transplant + 0.315 × log(Years on Dialysis + 1) - 0.099 × Diabetes × log(Years on Dialysis + 1) + 0.130 × (Years on Dialysis = 0) - 0.348 × Diabetes × (Years on Dialysis = 0) + 1.262 × Diabetes
