Organ Use Rate: A New Indicator of Donation and Transplantation Efficiency.

The conversion rate has emerged as a good indicator of the effectiveness of the transplantation process by showing the percentage of potential donors who become real donors, but it overestimates the number of organs that are actually used for transplantation in recipients. The incorporation of organ use rate, a new quality indicator that reflects the actual number of organs used for transplantation excluding those that are discarded in the surgical block, provides complementary information of great value when comparing transplantation in different regions. This new variable allows more accurate prediction of the waiting time for the transplantation of a certain organ in patients with nonreversible organic insufficiencies, while providing the national authorities a real response in relation to the percentage of the demand for organs that can be satisfied.
