A broadening donor pool, increased risk aversion, and inefficient organ allocation may all contribute to the long-term increase in the percentage of deceased donor kidneys discarded, concludes a study in Transplantation.
The researchers analyzed Organ Procurement and Transplantation Network data to explore possible reasons for the well-documented, two-decade-long increase in the US deceased donor kidney discard rate (DKR). Beginning at 5.1% in 1988, the KDR rose more or less steadily to a high of 19.1% in 2009. This trend occurred at a time when the number of kidneys nearly doubled, from 7705 to 14,394. The KDR subsequently stabilized
