How Kidney Donor Profile Index is calculated and used
The Kidney Donor Risk Index (KDRI) combines a variety of donor factors to summarize the risk of graft failure after kidney transplant into a single number. The KDRI expresses the relative risk of kidney graft failure for a given donor compared to the median kidney donor; values exceeding 1 have higher expected risk than the median donor, and vice versa.
The KDPI is a remapping of the KDRI onto a cumulative percentage scale, such that a donor with a KDPI of 80% has higher expected risk of graft failure than 80% of all kidney donors recovered last year and can be used to compute KDPI and KDRI for a hypothetical or actual donor. The calculations and assumptions mirror those used for computing KDPI and KDRI in DonorNet®.
- If diabetes or hypertension statuses are unknown, the calculator will assume the donor has the same chance as a randomly selected donor having the condition.
- If HCV status is unknown, the calculator will assume the donor is negative for HCV.
The KDPI is used in combination with EPTS to match some kidney donors and recipients.
