Background: The Eurotransplant acceptable mismatch program has improved transplantation access for highly-sensitised recipients. However, the benefits and costs of implementing such a program remain unknown.

Methods: Using decision analytical modelling, we compared the average waiting time for transplantation, overall survival gains (in life-years and quality-adjusted life-years gained) and costs of integrating an acceptable mismatch allocation model compared with the current deceased-donor kidney allocation model in Australia.

Results: Acceptable mismatches were identified in 12 of 28 (43%) highly-sensitised recipients using HLAMatchmaker. Inclusion of acceptable mismatches in the current allocation model improved the transplantation access for 4 (14%) highly-sensitised recipients, with an average reduction in waiting time of 34 months (from 86 to 52 months). Compared with the current allocation model, incorporating an acceptable mismatch allocation model achieved an overall lifetime gain of 0.034 quality-adjusted life-years and savings of over $4,000 per highly-sensitised patient, with a small consequential loss of 0.005 quality-adjusted life-years and extra costs of  $800 for every reallocated patient.

Conclusions: Despite modest overall health gains, application of an acceptable mismatch allocation model is an equitable approach to improve transplantation access for highly-sensitised transplant candidates without compromising the overall health benefits among the other patients on the deceased-donor waitlist in Australia.
