This tool calculates the UK Kidney Donor Risk Index used in the 2019 deceased donor matching scheme as well as the earlier risk index published by Watson et al. in 2012. They are simpler risk scoring system for deceased kidney donors than the equivalent KDRI used in the United States, and have slightly better performance than the US score when applied to outcomes from deceased donor kidney transplants in the UK.
The scores are presented both numerically and in quartile of risk. The analyses leading to this indices were based on different cohorts of patients, so donors appear to have a higher cohort of risk for 2019 score.
