Balancing organ quality, HLA-matching, and waiting times: impact of a pediatric priority allocation policy for deceased donor kidneys in Quebec.

Deceased donor kidney allocation policy must balance the desire for high-quality organs, good human leukocyte antigen (HLA) matching, and minimal waiting times. We describe a 10-fold reduction in waiting times and an improvement in nonimmunologic indices of organ quality for child recipients after a change in organ allocation policy in Quebec, Canada. The new policy gives first priority to children (<18 yr) irrespective of HLA matching or waiting time. HLA matching after the policy change was predictably much worse. This study highlights the trade-offs that must be considered both in setting allocation policy and in decisions for individual recipients. We also consider potential unintended negative effects of such a policy change.
