Kidney Donor Profile Index Calculator

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 from last year; 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.

This calculator 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®.

To calculate KDPI and KDRI for a donor, please complete the form below. All fields are required, however, if diabetes or hypertension status are unknown, the calculator will assume the donor has the same chance as a randomly selected donor of having the condition. If HCV status is unknown, the calculator will assume the donor is negative for HCV.

Interpretation: The estimated risk of kidney graft failure from this donor is higher than 70% of all kidney donors recovered in 2012 and 1.22 times that of the median donor from 2012.

The KDPI combines many dimensions of information about a donor, including clinical parameters and demographics, to summarize the quality of the donor kidneys into a single number useful for decision-making.
