The cost-effectiveness of using payment to increase living donor kidneys for transplantation

Abstract

Background and objectives For eligible candidates, transplantation is considered the optimal treatment compared with dialysis for patients with ESRD. The growing number of patients with ESRD requires new strategies to increase the pool of potential donors. Design, setting, participants, & measurements Using decision analysismodeling, this study compared a strategy of paying living kidney donors to waitlisted recipients on dialysis with the current organ donation system. In the base case estimate, this study assumedthat the number ofdonorswould increase by 5%with a payment of $10, 000.Quality of life estimates, resource use, and costs (2010 Canadian dollars) were based on the best available published data. Results Compared with the current organ donation system, a strategy of increasing the number of kidneys for transplantation by 5% by paying living donors $10, 000 has an incremental cost-savings of $340 and a gain of 0.11 quality-adjusted life years. Increasing the number of kidneys for transplantation by 10% and 20% would translate into incremental cost-savings of $1640 and $4030 and incremental quality-adjusted life years gain of 0.21 and 0.39, respectively. Conclusion Although the impact is uncertain, this model suggests that a strategy of paying living donors to increase the number of kidneys available for transplantation could be cost-effective, even with a transplant rate increase of only 5%. Future work needs to examine the feasibility, legal policy, ethics, and public perception of a strategy to pay living donors. © 2013 by the American Society of Nephrology.
