Nondirected living kidney donors--Abundant (the movie, in progress)

 Abundant is a movie in the making,  a documentary about altruism, focused on non-directed living kidney donors, who start kidney exchange chains. It isn't done yet, but now they are in the editing process...

"Abundant is a feature-length documentary film about the complex, human experience of giving.  To fully understand giving, Abundant enters the world of extreme altruism.  And there are no more extreme altruists than non-directed living kidney donors.  These rare individuals give a kidney away to a complete stranger.  It’s all risk, no reward.  Or is it? 

"Abundant features true stories of non-directed kidney donors recorded live on stage at the performance art show CrowdSource for Life.  Their stories illustrate the unimaginable impact of extreme giving.  It’s obvious their kidney donations saved another person’s life, but there is so much more involved.

"Insights from experts from the worlds of economics, spirituality, business, the arts, psychology and neuroscience, frame and explain the altruistic psyche. In his interview for Abundant, Buddhist monk Bhante Sujatha described giving with a literal translation from his Sri Lankan language, Sinhala.  In Sinhala, giving means, “It leaves my hand.”  That’s a clear, simple and elegant concept.  Yet so many of us struggle with the genuine act of giving and the abundance required to give openheartedly.

"Through stories, commentary and experiences, Abundant explores how our culture struggles with abundance and what we can do to become more altruistic as a community."

Kidney exchange (and other bits of market design) in the New York Times

 Peter Coy, the veteran New York Times economics columnist, writes about kidney exchange, after an interview/conversation sparked by a recent working paper of mine, Market Design and Maintenance. (He's a rare economic journalist who reads economists' papers.)

Here's his column, published yesterday afternoon:

The Economist Who Helped Patients Get New Kidneys, Feb. 5, 2024, 3:00 p.m. ET, By Peter Coy

He's also a rare interviewer: his column includes the names of more of my coauthors than I can recall in any other interview. In order of appearance: Tayfun Sonmez and Utku Unver, Frank Delmonico, Susan Saidman, Mike Rees (implicitly) when he names Mike's nonprofit Alliance for Paired Kidney Donation, and Elliott Peranson.  Market design is, after all, a team sport.

Here's his concluding paragraph:

"What is it like to straddle the worlds of academia and practice? I asked. “It takes a lot of patience,” he said. “Market design is outward-facing. I learn from trying to persuade people who aren’t economists. It’s a lot of fun also. Sometimes you have to go beyond your completely reliable scientific knowledge.”

Paying it forward

 Scott Cunningham, an economist who devotes a lot of his efforts to providing public goods, recently had a post on the phrase "paying it forward." He writes that he connected it with a movie with a similar name, but has recently come to view it differently (for reasons I find too embarrassing to quote, but related to the fact that I use the phrase now and then.)

Wikipedia says "Pay it forward is an expression for describing the beneficiary of a good deed repaying the kindness to others instead of to the original benefactor."  It goes on to say "Robert Heinlein's 1951 novel Between Planets helped popularize the phrase."  I could have first seen it there, as I read much of Heinlein's science fiction when I was a boy.

My associations with the phrase now mostly come from the motivations and actions of some living kidney donors, particularly in kidney exchange chains.

The phrase is certainly is evocative of what we do so much of in academia (when we're doing academia well): it describes the relationship between studying and teaching, and between teachers and students.

********

Scott's post announced that, as part of paying things forward, he's funding a prize for young economists.

Freakonomics replay and update on kidney exchange and organ donation

 Freakonomics Radio yesterday revisited some of their old podcasts about kidney exchange. In one, they interview me, and in another, they interview Ned Brooks, who listened to that interview and went on to become a non-directed kidney donor and to found an organization to support other kidney donors, the NKDO, National Kidney Donation Organization.  You can listen and/or read the transcript at this link:

EPISODE 209

Make Me a Match (Update)

"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.

"Last month, the federal government announced plans to modernize the U.S. organ-donation system. They want to speed up the process by which organ-transplant patients are matched with donated organs, and they also want to reduce racial inequities in the system. When we saw this news, we decided to go into our archive and put together the episode you’re about to hear. It’s a mashup of a 2015 episode, No. 209, called “Make Me a Match,” and a portion of a 2016 episode, No. 237, which includes a personal story from a listener who was inspired by that earlier episode to make a remarkable decision. All the relevant facts and figures have been updated. As always, thanks for listening."

The power of kidneys, altruism, and books. (And recommendation of a doctor in the UK)

 Here's a story, about kidneys and about books, in inews.co.uk:

‘It’s a gift with no conditions attached’: Why I donated my kidney to a person I’ll never meet. 250 people die each year in the UK because there are not enough kidneys available. So when GP Richard Armitage discovered altruistic donation was possible, he gave away an organ. By Tom Ough

"Despite being a GP, Richard Armitage had spent most of his career unaware that altruistic donations were possible. In this respect, Armitage, 34, was like many of his colleagues in the medical profession. That changed in 2017. Armitage, visiting the Nobel Laureate Museum Stockholm, bought a book by Alvin Roth, an economist who won a Nobel Prize in 2012. The book was Who Gets What — and Why: The New Economics of Matchmaking and Market Design, and in it Roth wrote how we allocate things within markets that aren’t dictated by money.

"Examples include the allocation of children to schools, doctors to hospitals, and kidneys to people with end-stage renal disease. Roth discussed what is known as non-directed altruistic kidney donations – in short, kidneys donated to strangers. Sitting on the plane home, Armitage read the book with fascination. When he returned to Nottingham he checked the NHS website to see whether non-directed altruistic kidney donation was possible in the UK. It was.

...
"In 2018 altruistic donors began being routinely added to the UK Living Kidney Sharing Scheme (UKLKSS), which oversees this sharing of organs by living donors. Apparently as a result of the move, in 2019 there was a 60 per cent rise in altruistic donations – from 124 to 183. Twenty-eight per cent of kidney transplants are now from living donors.
...
"It seemed a good application of the kind of moral philosophy that Armitage had discovered the same year, 2017, when he read Famine, Affluence and Morality. It is an influential essay in which Peter Singer, an Australian philosopher, argued that the West should be donating far more resources to humanitarian causes.
...
"All of Armitage’s intellectual discovery, including his reading of Roth’s writing on kidney donation, happened in one year, 2017 – also the year that Armitage finished his GP training. It marked the end of “a 10-year head-down slog” that began with the first day of medical school. “After I passed my last exam, it felt like I finally lifted my head up and asked: ‘But why am I doing this?’”

"And so Armitage’s first conversation with his regional kidney transplant centre was followed by an appointment with a Living Donor Nurse, who explained what donation would entail: the testing, the preparation, the surgery. Armitage was invited to speak to his loved ones and consider whether he was ready; it turned out he wasn’t.

"There were several hold-ups. At first, Armitage felt the beginning of his GP career was the wrong time to take weeks off work. Then Covid stalled the NHS’s kidney-sharing scheme. Armitage still wanted to donate his kidney, and successfully underwent a battery of investigations: a renal tract ultrasound scan, an electrocardiogram, chest X-ray, various fasted blood tests, and an X-ray of his kidney. As per the requirements of the donation scheme, Armitage met a clinical psychologist to discuss his state of mind, put the psychologist in touch with a loved one in order to independently assess his state of mind, and met a representative of the Human Tissue Authority to ensure that he was not donating his kidney under duress or for financial gain.
...
"Armitage spent several weeks in Ukraine as part of his work for the charity UK-Med, which sent British medics to deliver emergency healthcare. “That obviously meant I couldn’t continue with the donation process,” he says with some understatement. But when he got home, he told the donor team he was ready. “Can we crack on?”, he asked.

"The operation was on 23 November. Everything was in place; Armitage was part of a chain on which three people with end-stage renal disease were due a kidney.
...
"And just before he was discharged – three days after surgery, having convinced the hospital staff he was ready to take care of himself – he was informed that all the recipients in the chain now had working kidneys. “That was a very meaningful moment that made it all worthwhile,” says Armitage."

Kidney exchange collaboration between Stanford and APKD

 I recently had occasion to review the long collaboration between my Stanford colleagues and Mike Rees and the Alliance for Paired Kidney Donation. It turns out that, together with other coauthors, Mike and his APKD colleagues have written well over a dozen papers with me and my colleagues at Stanford.  (My own collaboration with Mike and APKD goes back to when Itai Ashlagi and I were still in Boston, where my earliest papers on kidney exchange were with  Tayfun Sönmez and Utku Ünver, and with Frank Delmonico and his colleagues at the New England Program for Kidney Exchange.)

Kidney exchange in The Times of India

Prospects for improving kidney exchange in France

A recent article in Néphrologie & Thérapeutique simulates how kidney exchange in France could possibly be made substantially more effective, following liberalizations in the law. (The article is in French, but also has an English abstract.) A promising feature is that the article is a collaboration between physicians and market design economists.

Perspectives pour une évolution du programme de don croisé de reins en France

Perspectives for future development of the kidney paired donation programme in France by Julien Combe, Victor Hiller, Olivier Tercieux,  Benoît Audry, Jules Baudet, Géraldine   Malaquin, François Kerbaul, Corinne Antoine, Marie-Alice Macher, Christian Jacquelinet, Olivier Bastien, and Myriam Pastural

Abstract: "Almost one third of kidney donation candidates are incompatible (HLA and/or ABO) with their directed recipient. Kidney paired donation allows potential donors to be exchanged and gives access to a compatible kidney transplant. The Bioethics Law of 2011 authorised kidney paired donation in France with reciprocity between 2 incompatible “donor-recipient” pairs. A limited number of transplants have been performed due to a too restricted authorization compared to other European practices. This study presents the perspectives of the new Bioethics Law, enacted in 2021, which increases the authorised practices for kidney paired donation in France. The two simulated evolutions are the increase of the number of pairs involved in a kidney paired donation to 6 (against 2 currently) and the use of a deceased donor as a substitution to one of living donor. Different scenarios are simulated using data from the Agence de la Biomedecine; incompatible pairs registered in the kidney paired donation programme in France between December 2013 and February 2018 (78 incompatible pairs), incompatible transplants performed during the same period (476 incompatible pairs) and characteristics of deceased donors as well as proposals made over this period. Increasing the number of pairs has a limited effect on the number of transplants, which increases from 18 (23% of recipients) in the current system to 25 (32% of recipients) when 6 pairs can be involved. The use of a deceased donor significantly increases the number of transplants to 41 (52% of recipients). This study makes it possible to evaluate the increase in possibilities of kidney transplants by kidney paired donation following the new bioethics law. A working group and an information campaign for professionals and patients will be necessary for its implementation."

While the paper focuses on the situation in France, it's opening lines could have been written anywhere:

"La France, comme l’ensemble des pays du monde, souffre d’une pénurie de greffons rénaux de sorte que le nombre de malades en attente d’une greffe de rein ne cesse de croître." [France, like all countries in the world, suffers from a shortage of kidney transplants so that the number of patients waiting for a kidney transplant continues to grow."

Here's hoping that the authors will succeed in their plans to use deceased-donor initiated chains to save more lives in France.

The Future of Living Donor Kidney Transplants May 7, 2022 (online webinar hosted at U. Chicago)

Yesterday I posted about the increasing incidence and prevalence of end stage renal disease

On Saturday I'll be taking part in a medical education webinar, open to the general public, on avenues to increase the availability of safe, ethical and legal kidney transplants.  Some will find it controversial*, even repugnant, since one of the big topics is the ethics of compensating kidney donors. (I'll be talking about some  of the incremental improvements that have been and can be pursued while that discussion goes on. Some of those have also had to overcome some opposition...)

There's an all-star cast of speakers.

Kidney Paired Donation Chains Initiated by Deceased Donors

 Starting kidney exchange chains with a deceased donor is a good idea whose time is coming.  

Wen Wang, Alan B. Leichtman, Michael A. Rees, Peter X.-K. Song, Valarie B. Ashby, Tempie Shearon, John D. Kalbfleisch,  Kidney Paired Donation Chains Initiated by Deceased Donors, Kidney International Reports, 2022, https://doi.org/10.1016/j.ekir.2022.03.023.

(https://www.sciencedirect.com/science/article/pii/S2468024922012438)

"Abstract:

• Introduction: Rather than generating one transplant by directly donating to a candidate on the waitlist, deceased donors (DD) could achieve additional transplants by donating to a candidate in a kidney paired donation (KPD) pool, thereby, initiating a chain that ends with a living donor (LD) donating to a candidate on the waitlist. We model outcomes arising from various strategies that allow DDs to initiate KPD chains. 

• Methods: We base simulations on actual 2016-2017 US DD and waitlist data and use simulated KPD pools to model DD initiated KPD chains. We also consider methods to assess and overcome the primary criticism of this approach, namely the potential to disadvantage Blood Type O waitlisted candidates. 

• Results: Compared to shorter DD initiated KPD chains, longer chains increase the number of KPD transplants by up to 5% and reduce the number of DDs allocated to the KPD pool by 25%. These strategies increase the overall number of Blood Type O transplants and make LDs available to candidates on the waitlist. Restricting allocation of Blood Type O DDs to require ending KPD chains with LD Blood Type O donations to the waitlist markedly reduces the number of KPD transplants achieved. 

• Conclusion: Allocating fewer than 3% of DD to initiate KPD chains could increase the number of kidney transplants by up to 290 annually. Such use of DDs allows additional transplantation of highly sensitized and Blood Type O KPD candidates. Collectively, patients of each blood type, including Blood Type O, would benefit from the proposed strategies."
