Of 30,779 deceased-donor kidneys recovered for transplantation in 2023¬¬, 8583 (28%) were not used. The National Academies of Sciences, Engineering, and Medicine declared kidney non-utilization a critical problem that mandates immediate attention and remedy. Highly prioritized candidates receive many offers for kidneys that vary greatly in quality; these candidates usually refuse offers for non-ideal kidneys sequentially while the clock counts down to kidney non-use. Minutes matter because kidneys that have been recovered and stored degrade quickly while organ procurement organizations (OPOs) make offers for one patient at a time according to the allocation ordering. Many candidates would certainly have benefitted from receiving one of these non-ideal kidneys. I will describe as best I can why and how donated kidneys that could provide benefit go unused, and how I am applying discrete event simulation models to suggest alternative allocation rules that might help. My argument is that reducing the number of donated kidneys that go untransplanted is a wicked problem. In fact, some and possibly most of the problems discussed at this IMSI conference should be reframed as wicked problems by enlarging the boundaries of the solution sets considered. Wicked problems are problems that I fear those with training like ours will reflexively formulate as optimization problems; wicked problems in fact are "ill-formulated, so neither the information to be obtained nor the solution set to be considered can be defined, and the ramifications in the whole system are thoroughly confusing."
