The Power of Altruistic Kidney Donation
The podcast episode discusses the concept of altruistic kidney donation and the power of kidney exchange. Al Roth's work in market design and matching algorithms has revolutionized the organ transplant system, allowing for the creation of kidney chains that can save the lives of multiple patients. The episode highlights the potential impact of being an altruistic kidney donor and the leverage it creates in initiating kidney chains. The process of becoming a donor involves thorough medical testing and support from healthcare professionals. Family members may have varying reactions, but gaining an understanding of the surgical procedures and the potential to save lives often alleviates any concerns.
The Need for Kidney Transplants and Organ Shortage
The episode sheds light on the critical need for kidney transplants, stating that there are over 122,000 people on the organ transplant waiting list in the US, with the majority requiring a kidney. The supply of donated organs, particularly kidneys, lags far behind the demand. The limited availability of compatible deceased donors compounds the issue. However, the fact that healthy individuals have two kidneys and only need one presents an opportunity for living kidney donation. The podcast emphasizes that kidney exchange programs, like the ones Al Roth helped design, maximize the potential for kidney transplants by facilitating chains of transplant surgeries involving non-directed donors and recipients.
The Role of Market Design and Altruism in Organ Transplants
The podcast highlights the role of market design and the influence of altruistic actions in facilitating organ transplants. Al Roth's application of market principles to kidney donation has allowed for the organization of kidney chains, where donors who are not a match for their intended recipients donate to other recipients in need. These chains optimize the use of organ resources and enhance the chances of saving lives. The episode emphasizes that the success of these organ exchange programs relies on the participation of altruistic donors. Potential donors undergo extensive testing and evaluation to ensure their suitability for donation, and they are supported by advocates throughout the process.
Kidney Exchange as a Teaching Tool
The podcast episode highlights how kidney exchange started as a teaching tool and evolved into a practical solution. Initially, the speaker used kidney exchange as an example in a toy model to teach students. However, the concept gained traction, leading to the first kidney exchange in the United States in 2000. This marked the beginning of kidney paired exchange programs, where incompatible patient donor pairs would match with other couples, allowing the healthy member of each couple to donate a kidney to the needy member of another couple.
The Power of Altruistic Kidney Donation
This part of the podcast explores the impact of altruistic kidney donation and the role it plays in expanding kidney exchange opportunities. Jody Shakley Wright, an altruistic kidney donor, shares her experience of being inspired by a TV show and eventually donating her kidney to a recipient in need. Al Roth's algorithm helped match Jody's kidney with Julie Park in a kidney chain. This chain started with Jody and continued as subsequent donors in the chain enabled multiple transplants, making Jody's one act of kindness have a multiplier effect in improving the lives of several people.
Sure, markets work well in general. But for some transactions — like school admissions and organ transplants — money alone can’t solve the problem. That’s when you need a market-design wizard like Al Roth. Plus: We hear from a listener who, inspired by this episode, made a remarkable decision.
