Global Kidney Exchange supported by the European Society of Transplantation's committee on Ethical, Legal, and Psychosocial Aspects of Transplantation .

Quite some time ago, the European Society for Organ Transplantation (ESOT) charged its committee on Ethical, Legal, and Psychosocial Aspects of Transplantation (ELPAT) with the task of evaluating those aspects of global kidney exchange (GKE). GKE had been greeted in some quarters with a number of dramatic accusations (e.g. that it was a form of organ trafficking), and the ELPAT committee tried to consider each of them.  Interestingly, the committee included members who I surmise started with a wide range of views, from cautious support to active hostility to GKE.

The final report, just published in Transplant International,  (which is the official journal of ESOT) is one that I think the committee can be proud of.  While you can tell that some committee members retain reservations about GKE, they nevertheless all agreed on a report that finds all of the principal objections raised against GKE to be unfounded.  Together with the even more clearly stated support for GKE in the Lancet, I think that this may mark a turning point: it certainly marks that GKE is receiving growing (and well deserved) support.

"Summary: This paper addresses ethical, legal, and psychosocial aspects of Global Kidney Exchange (GKE). Concerns have been raised that GKE violates the nonpayment principle, exploits donors in low‐ and middle‐income countries, and detracts from the aim of self‐sufficiency. We review the arguments for and against GKE. We argue that while some concerns about GKE are justified based on the available evidence, others are speculative and do not apply exclusively to GKE but to living donation more generally. We posit that concerns can be mitigated by implementing safeguards, by developing minimum quality criteria and by establishing an international committee that independently monitors and evaluates GKE’s procedures and outcomes. Several questions remain however that warrant further clarification. What are the experiences and views of recipients and donors participating in GKE? Who manages the escrow funds that have been put in place for donor and recipients? What procedures and safeguards have been put in place to prevent corruption of these funds? What are the inclusion criteria for participating GKE centers? GKE provides opportunity to promote access to donation and transplantation but can only be conducted with the appropriate safeguards. Patients’ and donors’ voices are missing in this debate." 

Here's their introduction:

"In 2017, Rees et al. [1] introduced “Global Kidney Exchange” (GKE), an international kidney exchange program that facilitates cross‐border exchanges between immunologically incompatible donor–recipient pairs in high‐income countries (HIC) and biologically compatible but financially impoverished donor–recipient pairs in low‐ to middle‐income countries (LMIC). GKE aims to overcome immunologic barriers in the developed world and poverty barriers in the developing world. The underlying rationale is that financial barriers prevent transplantation much more frequently than organ scarcity. The number of patients dying annually worldwide from end‐stage kidney disease due to inadequate financial resources far exceeds the number of patients in developed countries placed on kidney transplantation waitlists [1-3]. GKE has the potential to expand the genetic diversity of the donor pool which may help to transplant difficult‐to‐transplant, highly immunized patients [1]."

As they debunk the main arguments that have been made against GKE, I thought that some of these remarks were among the most interesting:

"Removing financial barriers to organ donation is an internationally agreed objective, enshrined, among others, in the World Health Organization’s (WHO) Guiding Principles on Human Cell, Tissue and Organ Transplantation and in the CoE Convention [13, 15]. These organizations highlight that prohibition of organ payments does not preclude reimbursing expenses incurred by the donor, including the costs of medical procedures [13, 17]. Given that countries’ legislation vary in their approach to what constitutes illicit payment versus legitimate reimbursement, it is doubtful whether GKE violates the nonpayment principle under all circumstances. For example, the University of Minnesota’s legal team vetted GKE and agreed to proceed. Other hospital legal teams have followed suit [1]."

...

"“[e]xploitation occurs when someone takes advantage of a vulnerability in another person for their own benefit, creating a disparity in the benefits gained by the two parties” [9]. It is hard to see, however, that this description of exploitation can be readily applied to GKE. Primarily, it is not clear that there is a significant disparity in benefits between recipients. Each patient receives a kidney transplant, and as Minerva et al point out, benefits are arguably greater for LMIC recipients, who get the additional benefit of their follow‐up care being paid for [33]. The same is true for the donors, who each obtain the desired benefit of their intended beneficiary receiving a transplant. Rather than there being a morally troubling disparity in benefit, GKE appears to offer either roughly equal benefit, or greater benefit for those who are allegedly exploited."

"It is also unconvincing to consider GKE exploitative on other grounds. Rather than failing to protect the vulnerable, it seems that GKE addresses specific vulnerabilities by offering protection to those who are (i) vulnerable to death from kidney failure or (ii) vulnerable to losing a loved one due to kidney failure. It is similarly unconvincing to suggest that GKE treats people merely as a means to an end. Instead, one can see that participants in LMIC are respected as individuals, with measures put in place to protect their welfare and to ensure that their participation is voluntary."

...

The claim that donors and recipients in LMIC are too poor or vulnerable to voluntarily engage in GKE is also debatable and could be seen as paternalistic. First of all, the risk that voluntariness is undermined does not apply specifically to GKE or to LMIC alone, but applies to living donation more generally [35].

...

"The proclamation that countries have to be self‐sufficient was first declared by the 2008 DoI and the WHO [73, 74] and has rapidly gained momentum since [75-77]. The argument to ban GKE because of the need to achieve self‐sufficiency raises various implications however. First of all, it implies that the need for countries to become self‐sufficient is more important than the lives that can be immediately saved through GKE. Is achievement of self‐sufficiency so important that it overrides life‐saving alternatives? Who has the authority to decide which approach should get priority? Why is it required that countries become self‐sufficient in organ donation and transplantation, while it is universally accepted for countries to rely on global exchanges of all other types of goods and services?

 ***********************

The ESOT/ELPAT committee apparently operated under rules that prevented them from investigating some claims that required evidence, so they included some questions for us in their paper, which we answer in the comment that appeared in the same issue of TI. (For example, there was some confusion about what escrow meant in connection with the money provided for the foreign donor and recipient's medical expenses after their return home...)

In any event, the large number of co-authors to our comment (21!) is another expression of the broad and international support that GKE is achieving.

Child marriage in Somalia

 The Guardian has the story:

'A race against time': the new law putting Somalia's children at risk of marriage: Child marriage in the country has increased during coronavirus – and now a newly-tabled bill would allow children as young as 10 to marry   by Moulid Hujale

"According to the latest government figures, 34% of Somali girls are married before they reach 18, and 16% of them before their 15th birthday.

"While children are married off for different reasons, such as the economic benefit of a dowry, and an increase in child marriage cases has been reported during the coronavirus pandemic, early marriage is rooted in Somali culture. An old Somali saying goes: “Gabadh ama god hakaaga jirto ama gunti rag,” which loosely translates as “a girl should either be married or in a grave”.

"Marriage under 18 is not illegal, although Somalia’s constitution prohibits it and the country is signed up to several international treaties promising to tackle it. In July 2014, the government signed a charter committing to end child marriage by 2020. But in August, the Somali parliament tabled a controversial bill that would allow a child to be married once they reached puberty, which can mean 10 years old. The sexual intercourse related crimes bill would also allow marriage if parents consented. The UN has called the bill “deeply flawed”.

Transplant transport: direct commercial flights boost deceased donor transplants, by Wang, Zheng, and Dai

Abstract

Nearly 5,000 patients die every year while waiting for kidney transplants, and an estimated 18% of procured kidneys are discarded. Such a polarized co-existence of dire scarcity and massive wastefulness has been mainly driven by insufficient pooling of cadaveric kidneys across geographic regions. Although numerous policy initiatives are aimed at broadening organ pooling, they rarely account for a key friction — efficient airline transportation, ideally direct flights, is necessary for long-distance sharing due to the time-sensitive nature of kidney transplantation. Conceivably, transplant centers may be reluctant to accept kidney offers from far-off locations without direct flights. In this paper, we estimate the effect of the introduction of new airline routes on broader kidney sharing. By merging the U.S. airline transportation and kidney transplantation datasets, we create a unique sample tracking (1) the evolution of airline routes connecting all the U.S. airports and (2) kidney transplants between donors and recipients connected by these airports. We estimate the introduction of a new airline route increases the number of shared kidneys by 7.3%. We also find a net increase in the total number of kidney transplants with the introduction of new routes. Notably, the post-transplant survival rate remains largely unchanged, though average travel distance increases after the introduction of new airline routes. Our results are robust to alternative empirical specifications and have important implications for improving access to the U.S. organ transplantation system.

Peter Cramton on the retail electricity market in California

 Peter Cramton* is an astute observer of electricity markets.  Here's his op-ed in the San Diego Union-Tribune:

Commentary: My monthly electric bill in Texas would be $250. In California, it is $1,000. Here’s why.

Here's the first paragraph:

"Rolling outages may appear to be a symptom of climate change. Extreme heat and intermittent renewables certainly challenge electricity markets. But these challenges can be met with good market design. The California market has flaws that make California electricity more expensive and less reliable than it should be. Fixing these flaws should be a priority."

and here's the final paragraph:

"California illustrates that good intentions do not necessarily produce good policy. Good policy is designed from what we know about markets and human behavior. Good policy is the only way to provide reliable electricity at least cost"

Who Gets In, and Why--an inside look at college admissions

Here's an essay from the WSJ, adapted from a forthcoming book with an evocative title, “Who Gets In and Why, by Jeffrey Selingo. The subtitle is A Year Inside College Admissions

The Secrets of Elite College Admissions: In the final ‘shaping’ of an incoming class, academic standards give way to other, more ambiguous factors by By Jeffrey Selingo, Aug. 28, 2020

"The year I was inside Emory University’s admissions office, the school received a record 30,000 applications for fewer than 1,400 spots in its incoming class. In early March, just weeks before official notices were scheduled to go out, the statistical models used by Emory to predict enrollment indicated that too many applicants had been chosen to receive acceptances. In the span of days, teams of admissions officers covering five geographical areas had to shift 1,000 applications from the thin “admit” stack to the much larger “deny” or “wait list” piles.

Matching inequality and strategic behavior under the Boston mechanism: Evidence from China's college admissions by Wu and Zhong

 Here's a paper that analyses the immediate acceptance ("Boston") algorithm that was in use in China's college admissions system in many provinces, in 2003.

Matching inequality and strategic behavior under the Boston mechanism: Evidence from China's college admissions

by BinzhenWu and Xiaohan Zhong

Games and Economic Behavior, Volume 123, September 2020, Pages 1-21,  https://doi.org/10.1016/j.geb.2020.05.007

Abstract: We examine matching inequality in students' matching outcomes for the Boston Mechanism in a large matching system, by measuring the degree of mismatch for each student. We link a student's mismatch with her reporting behavior of the first choice on her preference list to explore the reasons for matching inequality. Using administrative data from college admissions in China, we find significant gender differences, rural-urban gaps, and ethnic gaps in mismatching and first-choice behavior. These demographic differences exhibit various patterns and may be explained by risk aversion, information disadvantage, and minority-preferential admissions policies, respectively.

The econometrics of deceased kidney donation

Two papers have made me think about the power of econometric methods applied to studies of medical issues related to matching deceased donor kidneys to patients.

I recently heard Chuck Manski give a seminar on this paper published last year in PNAS:

One thing I took away from it is that proportional hazard (Cox) models are very popular in the medical literature, but they assume that effects (e.g. rejection of a graft) are proportional to time, and there are immunological processes that don't in fact have a constant hazard rate, but build up over time, so that isn't a good model for those things.

Predicting kidney transplant outcomes with partial knowledge of HLA mismatch

Charles F. Manski,  Anat R. Tambur, and Michael Gmeiner, PNAS October 8, 2019 116 (41) 20339-20345

"Abstract: We consider prediction of graft survival when a kidney from a deceased donor is transplanted into a recipient, with a focus on the variation of survival with degree of human leukocyte antigen (HLA) mismatch. Previous studies have used data from the Scientific Registry of Transplant Recipients (SRTR) to predict survival conditional on partial characterization of HLA mismatch. Whereas earlier studies assumed proportional hazards models, we used nonparametric regression methods. These do not make the unrealistic assumption that relative risks are invariant as a function of time since transplant, and hence should be more accurate. To refine the predictions possible with partial knowledge of HLA mismatch, it has been suggested that HaploStats statistics on the frequencies of haplotypes within specified ethnic/national populations be used to impute complete HLA types. We counsel against this, showing that it cannot improve predictions on average and sometimes yields suboptimal transplant decisions. We show that the HaploStats frequency statistics are nevertheless useful when combined appropriately with the SRTR data. Analysis of the ecological inference problem shows that informative bounds on graft survival probabilities conditional on refined HLA typing are achievable by combining SRTR and HaploStats data with immunological knowledge of the relative effects of mismatch at different HLA loci."

And here's a recent working paper that says that if we want to maximize life years added by transplant, more organs should go more quickly to healthier patients:

Choices and Outcomes in Assignment Mechanisms: The Allocation of Deceased Donor Kidneys

Nikhil Agarwal, Charles Hodgson, Paulo Somaini, August 17, 2020

"Abstract: While the mechanism design paradigm emphasizes notions of efficiency based on agent preferences, policymakers often focus on alternative objectives. School districts emphasize educational achievement; and transplantation communities focus on patient survival. However, it is unclear whether choice-based mechanisms perform well when assessed using these outcomes. This paper evaluates the assignment mechanism for allocating deceased donor kidneys on the basis of the additional patient life-years from transplantion (LYFT). We examine the role of choice in increasing LYFT and compare equilibrium assignments to benchmarks that remove choice. Our approach combines a model of choice and outcomes in order to study how selection induced in the mechanism produces the outcome of

interest, LYFT. We show how to identify and estimate the model using quasi-experimental variation resulting from the mechanism. The estimates suggest that the design in use selects patients with better survival prospects after a transplant and matches them well. It results in an average LYFT of 7.97, which is 0.88 years higher than a random assignment. However, there is scope for increasing the aggregate LYFT to 12.07. While some of this increase can be achieved by assigning transplanted patients to different donors, realizing the majority requires transplanting relatively healthy patients, who would have longer life-expectancy even without a transplant. Therefore, a policymaker faces a dilemma between transplanting patients that are sicker and those for whom life will be extended the longest."

Profile of Amy Finkelstein in the PNAS

 Profile of Amy N. Finkelstein by Jennifer Viegas

"“It is a very exciting time to be an economist,” says Amy Finkelstein, a professor of economics at the Massachusetts Institute of Technology (MIT) who was elected to the National Academy of Sciences in 2018. “Economics has become a rigorous science, combining theory and data to better understand how the world works and how to improve it.” Focusing on the healthcare sector in the United States, Finkelstein integrates economic models, empirical methods, and data to find solutions for problems facing health insurance markets and healthcare delivery systems. Her research carries implications for healthcare policy. Finkelstein’s Inaugural Article (1) reports that a nationwide Medicare reform influenced the treatment of patients who were covered by other kinds of health insurance. The findings suggest that such broad effects should be taken into account when formulating future healthcare policies.

"Three Generations of Women with Doctorates

"Finkelstein was born in New York City in 1973 to biologist parents, who both earned doctorates at The Rockefeller University. In 1940, her mother immigrated to the United States from Poland, where her maternal grandmother had received a doctorate in comparative literature at the University of Warsaw. Finkelstein says, “It is remarkable that a Jewish woman in the 1920s was able to earn a doctorate in Eastern Europe.” The Finkelstein family papers documenting their lives are archived at the US Holocaust Memorial Museum in Washington, DC."

2020 Best 40 Under 40 Professors: Övül Sezer, University of North Carolina at Chapel Hill Kenan-Flagler Business School

 BY: NATHAN ALLEN

Here's that Q&A from her interview:

"Professor I most admire and why:

"There have been so many professors who inspired me and influenced me in several ways and I am so grateful for all the things I learned from them. But one class that I took in college changed the course of my path. Back in college, I was studying math, spending a lot of time on equations and mathematical proofs. In a very serendipitous way, I ended up trying to take a graduate-level economics class, called “Experimental Economics” because I wanted to take a class where I didn’t have to do any weekly “problem set” but it still counted as credit. To be able to take the class as an undergrad, I needed the professor’s permission. The professor teaching the course happened to be Al Roth, who allowed me to the class and introduced me to the love of experiments. Through him, I started learning a lot about experiments, and how we can take our very own observations about life and test them. This was the first time I fell in love with experimental science, and this is where I am today. In addition to being a great professor, Al Roth is also a very thoughtful and a kind person. I feel tremendously grateful to have taken that class."

Surrogacy in the time of covid travel restrictions

 The NY Times has the story:

Mothers, Babies Stranded in Ukraine Surrogacy Industry--Virus travel bans are wreaking havoc on surrogacy agencies that help same-sex couples build families  By Maria Varenikova

"In one of the more bizarre consequences of coronavirus travel restrictions, biological parents, babies and surrogate mothers have become scattered and sometimes stranded in multiple countries for months this year.

"Ukraine, with its relatively permissive reproductive health laws and an abundance of willing mothers among a poor population, is a hub of the international business, executives in the industry and women’s rights advocates say.

"But Ukrainian law bans surrogacy for same-sex couples or for clients who wish to select the sex of the child. In response, a branch of the Ukrainian industry began moving women to other jurisdictions for impregnation and birth, often to legal gray zones like the largely unrecognized, Turkish-backed, splinter state of Northern Cyprus.

...

"The women travel to have an embryo implanted, return to Ukraine for seven months of pregnancy, then travel again to give birth.

"Virus travel restrictions drew attention earlier this year for blocking heterosexual parents from retrieving their babies inside Ukraine. At one point, 79 babies were stacked up in Kyiv, cared for by nurses, in cribs at a hotel.

...

"It is a very common illegal business in such countries as Northern Cyprus, Transnistria, Abkhazia and other unrecognized statelets, said Sergii Antonov, a lawyer and authority on reproductive law in Ukraine.

"In Northern Cyprus, the Ukrainian mothers give birth without a legal surrogacy contract. Instead, they renounce custody after birth, which allows the genetic parents to adopt the children. It is a legal process that can stretch for several weeks.

"In February and March, 14 Ukrainian mothers, fearful of being stranded by virus travel bans, left Northern Cyprus after giving birth but before completing the transfer to the genetic parents, leaving behind a crop of babies in legal limbo.

School choice with common preferences and incomplete information admits a winner's curse, by Kloosterman and Troyan

 Suppose that schools have an intrinsic quality that would affect the preferences of all students if they knew it, but some students are better informed than others. Then, for uninformed students, there can be a kind of winner's curse associated with being accepted to a school: the fact that it had seats available suggests that it might not be high quality.  Kloosterman and Troyan propose mitigating this by giving each student a secure school for which he/she has high enough priority to be admitted regardless of others' preferences: " a secure school is one with enough seats for j and every student who has higher priority than j. "  When all students have the same ordinal preferences at every state of the world, then the deferred acceptance algorithm with students proposing continues to make it a dominant strategy for informed students to state their true preferences, and there is an equilibrium that avoids the winners curse in which each uninformed student lists their secure school as their first choice.

School choice with asymmetric information: Priority design and the curse of acceptance

by Andrew Kloosterman and Peter Troyan 

Theoretical Economics, Volume 15, Issue 3, July 2020, Pages: 1095-1133

Abstract: We generalize standard school choice models to allow for interdependent preferences and differentially informed students. We show that, in general, the commonly used deferred acceptance mechanism is no longer strategy‐proof, the outcome is not stable, and may make less informed students worse off. We attribute these results to a curse of acceptance. However, we also show that if priorities are designed appropriately, positive results are recovered: equilibrium strategies are simple, the outcome is stable, and less informed students are protected from the curse of acceptance. Our results have implications for the current debate over priority design in school choice.

...

"How do secure schools help the uninformed? The problem for them is the curse of acceptance, and a secure school allows for them to have a default option that they can get in every state. Hence, the curse is entirely eliminated by allowing them to expect to get average utility, rather than always being left with the worst schools in every state. Theorem 1 formalizes this intuition to all markets in the common ordinal preferences model."

 Some rules seem clear: anyone born in the U.S. is an American citizen, as is any child of an American parent.  But in these partisan times, even clear rules are subject to argument, and questionable distinctions can be brought up to litigate old repugnances.

ABC has the story:

State Dept. fighting to deny US citizenship to gay couple's child: A federal judge ruled in June that the agency had to grant citizenship.  By Conor Finnegan

"The State Department is appealing a federal judge's decision that it must recognize the U.S. citizenship of a young girl born via surrogate to a gay couple -- prolonging one of many legal fights over its controversial policy that was deemed unconstitutional in June.

"Roee Kiviti and Adiel Kiviti of Chevy Chase, Maryland, are legally married and both U.S. citizens. Their daughter Kessem was born in Canada via a surrogate, so the State Department has argued in federal court that she is "born out of wedlock" and not entitled to birthright citizenship.

...

"The Kiviti's are not the only family in a legal battle with the department on this issue.

"According to Immigration Equality, Derek Mize and Jonathan Gregg, a gay couple in Atlanta, are also awaiting a ruling by a federal judge over their daughter Simone's citizenship.

"The group also represents Allison Stefania and Lucas Zaccari -- a lesbian couple fighting for their daughter's citizenship. She was born to Lucas, an Italian citizen, via in vitro fertilization, so the State Department ruled she was born out of wedlock to a non-U.S. citizen, disregarding Allison's U.S. citizenship and their marriage. The couple is also awaiting a decision."

The Canadian Resident Matching Service: a history

 Here's a brief history of the Canadian medical residency match:

Gallinger J, Ouellette M, Peters E, Turriff L. CaRMS at 50: Making the match for medical education [Les 50 ans du CaRMS: jumelage pour l’éducation médicale]. Can Med Educ J. 2020;11(3):e133-e140. Published 2020 Jul 15. doi:10.36834/cmej.69786

Abstract: "Entry into postgraduate medical training in Canada is facilitated through a national application and matching system which establishes matches between applicants and training programs based on each party’s stated preferences.

"Health human resource planning in Canada involves many factors, influences, and decisions. The complexity of the system is due, in part, to the fact that much of the decision making is dispersed among provincial, territorial, regional, and federal jurisdictions, making a collaborative national approach a challenge. The national postgraduate application and matching system is one of the few aspects of the health human resources continuum that is truly pan-Canadian.

"This article examines the evolution of the application and matching system over the past half century, the values that underpin it, and CaRMS' role in the process."

More on Deceased donors as non‐directed donors in kidney exchange chains

I anticipate that we  will be reading more in the future about kidney exchange chains started by a deceased donor kidney.  In the meantime, here are two recent papers:

Abstract

As proof of concept, we simulate a revised kidney allocation system that includes deceased donor (DD) kidneys as chain‐initiating kidneys (DD‐CIK) in a kidney paired donation pool (KPDP), and estimate potential increases in number of transplants. We consider chains of length 2 in which the DD‐CIK gives to a candidate in the KPDP, and that candidate’s incompatible donor donates to the deceased donor (DD) waitlist. In simulations, we vary initial pool size, arrival rates of candidate/donor pairs and (living) non‐directed donors (NDDs), and delay time from entry to the KPDP until a candidate is eligible to receive a DD‐CIK. Using data on candidate/donor pairs and NDDs from the Alliance for Paired Kidney Donation, and the actual DDs from the Scientific Registry of Transplant Recipients (SRTR) data, simulations extend over two years. With an initial pool of 400, respective candidate and NDD arrival rates of two per day and 3 per month, and delay times for access to DD‐CIK of 6 months or less, including DD‐CIKs increases the number of transplants by at least 447 over two years, and greatly reduces waiting times of KPDP candidates. Potential effects on waitlist candidates are discussed as are policy and ethical issues.

Abstract: "Kidney paired donation (KPD) is a valuable way to overcome immunological incompatibility in the context of living donation, and several strategies have been implemented to boost its development. In this article, we reviewed the current state of the art in this field, with a particular focus on advanced KPD strategies, including the most recent idea of initiating living donor (LD) transplantation chains with a deceased‐donor (DD) kidney, first applied successfully in 2018. Since then, Italy has been running a national program in which a chain‐initiating kidney is selected from a DD pool and allocated to a recipient with an incompatible LD, and the LD’s kidney is transplanted into a patient on the waiting list (WL).

"At this stage, since the ethical and logistic issues have been managed appropriately, KPD starting with a DD has proved to be a feasible strategy. It enables transplants in recipients of incompatible pairs without the need for desensitizing and also benefits patients on the WL who are allocated chain‐ending kidneys from LDs (prioritizing sensitized patients and those on the WL for longer)."

Organs for sale

 Given the heated discussions and intense repugnance that often accompany questions concerning compensation for organs, you might be surprised to find an American Organ Clearing House  that has a section devoted to Organs for Sale.  

The site appears to get a lot of support from religious institutions

Needless to say, although money plays an important role, this kind of commerce still involves a good deal of matching.
