Organ allocation in the United Kingdom.

Organ allocation procedures in the United Kingdom are monitored on a regular basis. Changes are frequently made to improve equity of access and outcomes, based on the performance of a current scheme and simulations of alternatives. This article summarizes current arrangements for the allocation of kidneys, livers and cardiothoracic organs, and illustrates the monitoring process. A new national pancreas allocation scheme is outlined and forthcoming developments in the allocation of livers and DCD donor kidneys are summarized.
