Health care and game theory - the case of kidney transplantation

View/ Open
Abstract
This thesis offers a concise, practice-oriented overview of how game theory and
matching theory can improve kidney transplantation. We frame the problem as
interdependent decision making among patients, donors, and transplant centers, which
calls for rules that align incentives and support cooperation. Transplantation is one of
the superior option for end-stage kidney disease, yet demand exceeds supply, creating
congestion on waiting lists for organs from deceased donors. Within this context,
better use of living donors and kidney-pair exchange programs, built on stable
matching algorithms, can resolve incompatibilities and raise the probability of
transplantation. This study consists of a review of international practice with a
simplified matching model to highlight desired properties such as stability,
transparency, efficiency, and equity. We conclude that a coordinated exchange
framework with clear compatibility criteria, a unified registry, and continuous metric
based evaluation can shorten waiting times and increase successful transplants,
benefiting both patients and the health system.
