Background: In 2010 a new pancreas allocation system (PAS) was approved by the OPTN and implemented in October 2014, shortly preceding the new kidney allocation system (KAS). This system combined pancreas and simultaneous pancreas-kidney (SPK) candidates onto one match-run, added qualifying criteria for SPK waiting time, and set the kidney to follow the pancreas nationwide. Post-implementation, the OPTN pancreas committee studied the impact of the new PAS and KAS.

Methods: Using OPTN data from 6 months post-KAS implementation (12/4/14 – 6/4/15) and the same time-period from the prior year, the analyses show the impact on deceased donor pancreas and kidney utilization by pancreas and kidney donor risk indexes (PDRI and KDRI) and other factors. Odds of recovery and discard for donors were used to test utilization trends, and changes in proportions were studied for trends in volumes.

Results: Utilization of pancreas did not change. Kidney recovery rates have increased for KDPI<35% and decreased for KDPI>85%. Sharing of kidneys for adult transplants have increased significantly post-implementation (p<0.01), and regional adult SPK transplants have increased (p=0.06). SPK transplants are being performed on recipients further on the match run than pre-implementation (p=0.03). The proportion of kidney transplants that are SPK remained constant post-implementation as pre- (~5.5%).

Conclusions: Despite an increase in national volumes of deceased donors and transplants within the 6 month period following KAS implementation, pancreas recovery rates remain constant. The increase in regional SPK transplants has not resulted in fewer local transplants and OPOs place SPKs further on the match-run than before. PAS has not interfered with kidney allocation, using the same % of kidneys for SPK as in the past.
