Kidney Allocation System

In the OPTN kidney allocation system, every kidney transplant donor is assigned a Kidney Donor Profile Index (KDPI) score and every potential adult kidney transplant recipient is assigned an Estimated Post Transplant Survival (EPTS) score.
The EPTS score is only used in kidney allocation when the donor has a KDPI of 20% or less. In other words, the EPTS is used to prioritize patients in only 20% of kidney allocations, while for 80% of allocations, EPTS is not used at all (Alliance Terminology & Data Resources May 2021)
