The Impact of prioritization on kidney and liver allocation in Israel

   Israel's  Organ Transplantation Law grants some priority on waiting lists for transplants to candidates who are first-degree relatives of deceased organ donors (i.e. whose family has given permission for someone's deceased organ donation) or who previously registered as organ donors themselves. (There's also a tiny priority for relatives of people who signed organ donor cards...)  Here are two papers that looks at the effect of those priorities on kidney and liver transplants, and how they interact with other priorities on waiting lists for Israeli organs.  

The first paper, on kidneys, concludes that the priorities are effective in reducing waiting time to transplant, and suggests that perhaps these priorities should not be so large compared to other existing priorities (e.g. for time on dialysis), or for priorities that could be established, e.g. for highly sensitized patients (who get high priority in the U.S., for example.)

Mor, Eytan, Meitar Bloom, Ronen Ghinea, Roi Anteby, Ronit Pasvolsky-Gutman, Ron Loewenthal, Ido Nachmani, and Tammy Hod. "The Impact of the Donor Card Holder Prioritization Program on Kidney Allocation in Israel." Transplantation (2024): 10-1097.

Abstract

Background: Since 2014, as part of a priority program within the Israeli Transplant Law, additional points were given to waitlisted candidates with donor cards. We assessed the impact on deceased donor kidney allocation.

Methods: This study enrolled all patients older than 18 y who underwent deceased donor kidney transplantation (January 2016–December 2019). Data were obtained from the National HLA Tissue Laboratory registry at the Sheba Medical Center. Patients were grouped by donor card status (ADI group) (not signed, 0 points; relative signed, 0.1 points; patient signed, 2 points; and relative donated, 9 points). The primary outcome was waiting time until kidney transplantation with and without the additional score.

Results: Four hundred forty-four patients underwent kidney transplantation during the study period: 281 (63%) were donor card holders (DCH) and 163 (37%) were not DCH. DCH with extra points waited 68.0 (±47.0) mo on average, compared with 94.6 (±47.3) mo for not DCH (P < 0.001). Donor card signers had a shorter time until transplant in a multivariable model. Without extra points, 145 recipients (32.6%) would have missed organs allocated to higher-scored candidates. Allocation changes occurred in 1 patient because of an additional 0.1 points, in 103 candidates because of an additional 2 points, and in 41 candidates because of an additional 9 points.

Conclusions: Additional DCH scores improved allocation and reduced waiting time for donor card signers and those with donating relatives. To enhance fairness, consideration should be given to reducing the score weight of this social criterion and raising scores for other factors, especially dialysis duration.

There are many fewer liver transplants than kidney transplants, and the effect of priority is less clear:

Ashkenazi, Tamar, Avraham Stoler, and Eytan Mor. "The effect of priority given to donor card holders on the allocation of livers for transplant—evidence from 7 years of the Israeli priority program." Transplantation 106, no. 2 (2022): 299-307.

Abstract

Background. The Israeli Transplant Law grants priority in organ allocation to patients signing a donor card. Liver transplant candidates get additional 2 points on their Model for End Stage Liver Disease score for signing a donor card, 0.1 points for a relative holding a card, and 5 points if a relative donated an organ. We studied the effect of the priority program on waiting list mortality and allocation changes due to priority.

Methods. Using Israeli Transplant data of 531 adult liver transplant candidates with chronic liver disease listed between 2012 and 2018 we compared waitlist mortality and transplant rate of candidates with and without priority. Then we analyzed liver allocations resulting from additional priority points and followed outcome of patients who were skipped in line.

Results. Of the 519 candidates, 294 did not sign a donor card, 82 signed, 140 had a relative sign, and for 3, a relative donated an organ. The rates of waitlist mortality in these 4 groups were 22.4%, 0%, 21.4%, and 0%, respectively, and the transplant rates were 50%, 59.8%, 49.3%, and 100%, respectively. Of the 30 patients who were skipped because of priority, 24 subsequently underwent transplant, 2 are on the waiting list, and 4 died within 0.75, 1.75, 7, and 17 mo.

Conclusions. The 2 points added to the Model for End Stage Liver Disease score were associated with lower waitlist mortality and higher transplant rate for candidates signing a donor card without significantly affecting access to transplant during allocation. Further research and consideration of optimal policy when granting priority for candidates signing a donor card should continue.

Organ transplants and capital punishment don't go well together

 I recently blogged about a paper by Robertson and Lavee in the American Journal of Transplantation, looking at surgeries conducted in China before 2015, a period in which China acknowledged that most transplants there were conducted with organs from executed prisoners.  Now they summarize their report in a column in the WSJ.

In China, New Evidence That Surgeons Became Executioners. Clinical reports recount scores of cases in which organ donors were alive when operations began.  By Jacob Lavee and Matthew P. Robertson

"The Wuhan doctors write: “When the chest of the donor was opened, the chest wall incision was pale and bloodless, and the heart was purple and beating weakly. But the heartbeat became strong immediately after tracheal intubation and oxygenation. The donor heart was extracted with an incision from the 4th intercostal sternum into the chest. . . . This incision is a good choice for field operation where the sternum cannot be sawed open without power.”

"By casually noting that the donor was connected to a ventilator (“tracheal intubation”) only at midsurgery, the physicians inadvertently reveal that the donor was alive when the operation began.

...

"Our findings end in 2015, but we think the abuse likely continues. Medical papers like those we studied were first unearthed by Chinese grass-roots investigators in late 2014, and it would have been simple to command journals to stop publishing the incriminating details after that. While China claims to have stopped using prisoners in 2015, our previous research raises doubts. In a 2019 paper in the journal BMC Medical Ethics, we used statistical forensics to show that the official voluntary-organ donation numbers were falsified, inflating the success of a modest voluntary organ-donation reform program used to buttress the reform narrative.

"Global medical leaders have largely dismissed such concerns. The World Health Organization took advice from Chinese transplant surgeons in the establishment of its anti-organ-trafficking task force—and then installed them on the membership committee. In 2020, WHO officials joined long-time apologists for China’s transplant system, attacking our previous research showing falsified numbers."

...

Mr. Robertson is a research fellow with the Victims of Communism Memorial Foundation and a doctoral candidate in political science at the Australian National University."

"Execution by organ procurement: Breaching the dead donor rule in China," by Matthew P. Robertson, and Jacob Lavee in the AJT

 Prior to 2015, it was legal in China to transplant organs recovered from executed prisoners. When I visited China in those days to talk about kidney transplantation from living donors, it was sometimes pointed out to me that, as an American, I shouldn't object to the Chinese use of executed prisoner organs, because we also had capital punishment in the US, but we "wasted the organs."  I replied that in the US we had both capital punishment and transplantation, but were trying to limit one and increase the other, and that I didn’t think that either would be improved by linking it to the other.  

So here's a just-published retrospective paper looking at Chinese language transplant reports prior to 2015, which identifies at least some instances that it regards as "execution completed by organ procurement."

Execution by organ procurement: Breaching the dead donor rule in China, by Matthew P. Robertson1, and Jacob Lavee2, American Journal of Transplantation, Early View, First published: 04 April 2022 https://doi.org/10.1111/ajt.16969

Abstract: The dead donor rule is fundamental to transplant ethics. The rule states that organ procurement must not commence until the donor is both dead and formally pronounced so, and by the same token, that procurement of organs must not cause the death of the donor. In a separate area of medical practice, there has been intense controversy around the participation of physicians in the execution of capital prisoners. These two apparently disparate topics converge in a unique case: the intimate involvement of transplant surgeons in China in the execution of prisoners via the procurement of organs. We use computational text analysis to conduct a forensic review of 2838 papers drawn from a dataset of 124 770 Chinese-language transplant publications. Our algorithm searched for evidence of problematic declarations of brain death during organ procurement. We find evidence in 71 of these reports, spread nationwide, that brain death could not have properly been declared. In these cases, the removal of the heart during organ procurement must have been the proximate cause of the donor's death. Because these organ donors could only have been prisoners, our findings strongly suggest that physicians in the People's Republic of China have participated in executions by organ removal.


"how should we understand the physician's role in a context where executed prisoners are the primary source of transplant organs? Might the transplant surgeon become the de facto executioner? Evidence suggestive of such behavior has emerged over many years from the People's Republic of China (PRC).8-14 To investigate these reports, this paper uses computational methods to examine 2838 Chinese transplant-related medical papers published in scientific journals, systematically collecting data and testing hypotheses about this practice. By scrutinizing the clinical procedures around intubation and ventilation of donors, declaration of brain death, and commencement of organ procurement surgery, we contribute substantial new evidence to questions about the role of PRC physicians in state executions.

...

"The data we rely on in this paper involves transplant surgeries from 1980 to 2015. During this period, there was no voluntary donation system and very few voluntary donors. According to three official sources, including the current leader of the transplant sector, the number of voluntary (i.e., non-prisoner) organ donors in China cumulatively as of 2009 was either 120 or 130,30-32 representing only about 0.3% of the 120 000 organs officially reported to be transplanted during the same period (on the assumption that each voluntary donor gave three organs).18, 33, 34 The leader of China's transplant sector wrote in 2007 that effectively 95% of all organ transplants were from prisoners.35 According to official statements, it was only in 2014 that a national organ allocation system could be used by citizens.36

...

"Procuring vital organs from prisoners demands close cooperation between the executioner and the transplant team. The state's role is to administer death, while the physician's role is to procure a viable organ. If the execution is carried out without heed to the clinical demands of the transplant, the organs may be spoiled. Yet if the transplant team becomes too involved, they risk becoming the executioners.

"Our concern is whether the transplant surgeons establish first that the prisoners are dead before procuring their hearts and lungs. This translates into two empirical questions: (1) Is the donor intubated only after they are pronounced brain dead? And (2) Is the donor intubated by the procurement team as part of the procurement operation? If either were affirmative the declaration of brain death could not have met internationally accepted standards because brain death can only be determined on a fully ventilated patient. Rather, the cause of death would have been organ procurement.

...

"We define as problematic any BDD in which the report states that the donor was intubated after the declaration of brain death, and/or the donor was intubated immediately before organ procurement, as part of the procurement operation, or the donor was ventilated by face mask only.

...

"The number of studies with descriptions of problematic BDD was 71, published between 1980 and 2015. Problematic BDD occurred at 56 hospitals (of which 12 were military) in 33 cities across 15 provinces. 

...

"We have documented 71 descriptions of problematic brain death declaration prior to heart and lung procurement. From these reports, we infer that violations of the DDR took place: given that the donors could not have been brain dead before organ procurement, the declaration of brain death could not have been medically sound. It follows that in these cases death must have been caused by the surgeons procuring the organ.

"The 71 papers we identify almost certainly involved breaches of the DDR because in each case the surgery, as described, precluded a legitimate determination of brain death, an essential part of which is the performance of the apnea test, which in turn necessitates an intubated and ventilated patient. In the cases where a face mask was used instead of intubation48, 49—or a rapid tracheotomy was followed immediately by intubation,50 or where intubation took place after sternal incision as surgeons examined the beating heart44—the lack of prior determination of brain death is even more apparent.

"If indeed these papers document breaches of the DDR during organ procurement from prisoners as we argue, how were these donors prepared for organ procurement? The textual data in the cases we examine is silent on the matter. Taiwan is the only other country we are aware of where death penalty prisoners’ vital organs have been used following execution. This reportedly took place both during the 1990s and then once more in March 2011.51, 52

...

"The PRC papers we have identified do not describe how the donor was incapacitated before procurement, and the data is consistent with multiple plausible scenarios. These range from a bullet to the prisoner's head at an execution site before they are rushed to the hospital, like Tsai's description, or a general anesthetic delivered in the operating room directly before procurement. Paul et al. have previously proposed a hybrid of these scenarios to explain PRC transplant activity: a lethal injection, with execution completed by organ procurement. 

...

"We think that our failure to identify more DDR violations relates to the difficulty of detecting them in the first instance, not to the absence of actual DDR violations in either the literature or practice. Our choice to tightly focus only on papers that made explicit reports of apparent DDR violations likely limited the number of problematic papers we ultimately identified.

...

"As of 2021, China's organ transplant professionals have improved their reputation with their international peers. This is principally based on their claims to have ceased the use of prisoners as organ donors in 2015."

More on the UAE-Israel kidney exchange

If you're just tuning in, you can follow the story of the kidney exchange between the UAE and Israel here. The pairs who exchanged kidneys were an Israeli Arab husband and wife, a Jewish Israeli mother and daughter, and a mother and daughter who wish to be identified only as Arab residents of the United Arab Emirates.  (I joined their family at their home for a meal when I was in Abu Dhabi, but won't say more about them.)

It isn't a surprise that the donor in each pair couldn't donate to the intended recipient, because in each pair the recipient was a highly sensitized mother ( i.e. for whom it was hard to find a compatible kidney, because she had many antibodies against human proteins). During childbirth, mothers can develop such antibodies to the father's proteins that the children inherited. So the father and the daughters were incompatible donors, since the mother had antibodies against the paternal proteins (human leukocyte antigens) in their kidneys. Together with the fact that the mothers were quite hard to match, and that Israel and the UAE are both small, each with populations of around ten million, they had to look across national borders.

Cross border kidney exchange requires some diplomacy, particularly when the countries involved are getting together for the first time (and don't necessarily have a long history of cooperation). The key medical diplomats were Dr. Tamar Ashkenazi* the director of Israel Transplant and Dr Ali Abdulkareem Al Obaidli, Chairman of the UAE National Transplant Committee.  (Other key collaborators in the complicated logistics were Itai Ashlagi at Stanford and Atul Agnihotri and Mike Rees of the Alliance for Paired Kidney Donation.)  


So this was the plan:


And here's a picture of the Abu Dhabi kidney packed for shipping (masked in the picture are Sue and Mike Rees, who have a lot of experience with packing and shipping kidneys, another nurse whose name I don't know, and Dr. Muhammad Badar Zaman the UAE transplant surgeon who transplanted the  kidney that was on the way.


The little box taped to the top of the shipping container allows the kidney to be tracked in transit, via an app that gives you a picture of where it is at it travels:


And here's the swap of the two kidneys in shipping containers in the airport in Abu Dhabi (Tamar Ashkenazi and Dr. Ali are in the center, Atul and Mike are at the two ends...). Dr Ashkenazi was on both legs of the flight above--she flew in with the Israeli kidney and flew out with the UAE kidney.



On my last night in Abu Dhabi I had dinner with a lot of the docs. Across from me in the picture below are the two surgeons most actively involved in this exchange on the UAE side, transplant surgeon Dr. Zaman and the nephrectomy surgeon Dr. Hamid Reza Toussi.  Next to me is the nephrologist Dr. Mohamed Yahya Seiari.





Below is that whole dinner party. If you've been following these posts up til now, you've met all of them except the gentleman second from the left, Dr. Gehad ElGhazali, who is the head of the HLA lab, which is responsible for the data that allows the matching algorithm to predict which kidneys are compatible, and is responsible for the final 'crossmatch' tests that verify compatibility. Like all the other docs I encountered, he has a multi-international background. This reflects the UAE's very international population, which is why it seems a natural global hub for kidney exchange.




I only met the Israel participants in the exchange later, by Zoom: Shani Markowitz is the donor from the Jewish pair, and Walaa Azaiza is the recipient from the Israeli Arab pair.






The Israeli transplant surgeons are Dr Tony Karam at Rambam Hospital and Dr. Eitan Mor at Sheba Medical Center.

Lay attitudes towards organ donation from executed prisoners--by Bar-Hillel and Lavee

Here's a new paper reporting a survey, forthcoming in Behavioral Public Policy
Abstract:  A multi-item questionnaire concerning lay people's attitudes toward organ procurement without consent from executed prisoners was given to several hundred respondents. The items ranged from all-out condemnation (“It is tantamount to murder”) to enthusiasm (“It is great to have this organ supply”). Overall, we found two guiding principles upheld by most respondents: (1) Convicts have as much a right to their bodies and organs as other people, so the practice should be judged by the same standards as those that guide organ procurement from any donor. Procuring organs without consent is wrong. (2) Benefiting from those organs should be held to more lenient standards than are demanded for their procurement. So, benefitting from these ill-gotten organs should be tolerated.

Update: here's the published article
BAR-HILLEL, MAYA, and JACOB LAVEE. “Lay Attitudes toward Involuntary Organ Procurement from Death-Row Prisoners: No, But.” Behavioural Public Policy 6, no. 2 (2022): 325–41. doi:10.1017/bpp.2019.16.

A still-skeptical view of transplantation in China

My recent post on transplantation in China reported on optimistic assessments of the move away from using executed prisoners as a source of organs. Not everyone is optimistic: here's a recent editorial from the BMJ:

Engaging with China on organ transplantation
BMJ 2017; 356 doi: https://doi.org/10.1136/bmj.j665  (Published 07 February 2017)
by Wendy A Rogers, Matthew P Robertson, and Jacob Lavee

It starts with a story from the bad old days, and then turns to the current environment, saying in part:

"Since January 2015, China has vowed to halt the use of organs from executed prisoners. After a pilot in 2010-14, a procurement programme using donated organs from people who meet circulatory death criteria was rolled out nationally. There are now national transplantation registries and organ procurement organisations. Yet there is no new law or regulation in China banning the use of organs from executed prisoners. Nor have existing regulations permitting the use of prisoners’ organs been rescinded. Prisoners remain a legal source of organs if they are deemed to have consented before execution, thus permitting ongoing retrieval of organs from prisoners executed with or without due process.1

"The transplant registries are not open to public scrutiny or independent verification. Inexplicably high volumes of transplantation continue to take place in China,8 and wealthy foreigners can still obtain liver and heart transplants, booked in advance.11 The Transplantation Society’s former president Francis Delmonico acknowledged under oath at a recent US Congressional hearing that he cannot verify claims about reform in China. The main evidence for reform has simply been the public assertions of Huang Jiefu and other government officials."

NSF grant on collaborative kidney exchange: final report

I had a long-running NSF grant at the NBER in the years when I was at Harvard, called "Collaborative Research on Kidney Exchange." I recently filed a final report for the last leg of it, which ran from 2011-2016. (I'm still collaborating on kidney exchange, and anticipate doing so for some time, with my long term collaborators Itai Ashlagi and Mike Rees.)
Here is the link to the page on which you can find the report by searching for Federal Award ID Number 1061932  (that takes you to a page that has found the grant, and then you have to click on the number to get the report--your government dollars at work as we used to say:)

For some reason, the final report is missing many of the publications reported in the annual progress reports...but it gives an idea of what we were thinking when we began this leg of the work, and some of the different directions in which we were led.

A more comprehensive list of publications from this work in the period 2011-16 is below, I may have more to say about them in the future.

The effects of Israel's new organ transplantation law on family consent for deceased donation

Deceased donor organs are a scarce resource with the property that how they are allocated may influence their scarcity, by influencing the decisions of potential donors and their families.  Recent changes in Israeli law give us a window on this...
Incentivizing Authorization for Deceased Organ Donation With Organ Allocation Priority: The First 5 Years
by A. Stoler, J. B. Kessler, T. Ashkenazi, A. E. Roth, J. Lavee

American Journal of Transplantation, Volume 16, Issue 9, September 2016
Pages 2639–2645

Abstract

The allocation system of donor organs for transplantation may affect their scarcity. In 2008, Israel's Parliament passed the Organ Transplantation Law, which grants priority on waiting lists for transplants to candidates who are first-degree relatives of deceased organ donors or who previously registered as organ donors themselves. Several public campaigns have advertised the existence of the law since November 2010. We evaluated the effect of the law using all deceased donation requests made in Israel during the period 1998–2015. We use logistic regression to compare the authorization rates of the donors’ next of kin in the periods before (1998–2010) and after (2011–2015) the public was made aware of the law. The authorization rate for donation in the period after awareness was substantially higher (55.1% vs. 45.0%, odds ratio [OR] 1.43, p = 0.0003) and reached an all-time high rate of 60.2% in 2015. This increase was mainly due to an increase in the authorization rate of next of kin of unregistered donors (51.1% vs. 42.2%). We also found that the likelihood of next-of-kin authorization for donation was approximately twice as high when the deceased relative was a registered donor rather than unregistered (89.4% vs. 44.6%, OR 14.27, p < 0.0001). We concluded that the priority law is associated with an increased authorization rate for organ donation.

Transplant surgeons meet in Hong Kong amid questions about China's continued use of organs from executed prisoners

The NY Times has the story: Debate Flares on China’s Use of Prisoners’ Organs as Experts Meet in Hong Kong

It discusses a recent article in the American Journal of Transplantation:
Transplant Medicine in China: Need for Transparency and International Scrutiny Remains by T. Trey, A. Sharif, A. Schwarz, M. Fiatarone Singh, and J. Lavee

Here's the abstract of the article:
"Previous publications have described unethical organ procurement procedures in the People's Republic of China. International awareness and condemnation contributed to the announcement abolishing the procurement of organs from executed prisoners starting from January 2015. Eighteen months after the announcement, and aligned with the upcoming International Congress of the Transplantation Society in Hong Kong, this paper revisits the topic and discusses whether the declared reform has indeed been implemented. It is noticeable that China has neither addressed nor included in the reform a pledge to end the procurement of organs from prisoners of conscience, nor have they initiated any legislative amendments. Recent reports have discussed an implausible discrepancy of officially reported steady annual transplant numbers and a steep expansion of the transplant infrastructure in China. This paper expresses the viewpoint that, in the current context, it is not possible to verify the veracity of the announced changes and it thus remains premature to include China as an ethical partner in the international transplant community. Until we have independent and objective evidence of a complete cessation of unethical organ procurement from prisoners, the medical community has a professional responsibility to maintain the academic embargo on Chinese transplant professionals."

The NY Times story includes this:
"In an interview conducted on the messaging app WeChat, Huang Jiefu, a senior Chinese transplant official and a former deputy minister of health, appeared to defend the changes but simultaneously acknowledge they were far from perfect.

“We have finished walking the first step of a long march of 10,000 li, the task is heavy and the road far, but we are walking on a path of light,” he wrote. "

Organ transplants and executed prisoners in China

It appears that China's reliance on executed prisoners for transplantable organs is unlikely to end soon, but will be incorporated into what Chinese officials hope will be a more transparent system:

Govt seeks fairness in organ donor system for inmates

Updated: 2014-03-07 07:20

By Shan Juan (China Daily USA)


"China is set to further strengthen the regulation of organ donations from executed prisoners and integrate it into the existing public voluntary organ donation and allocation system, according to a political adviser close to the situation.
Huang Jiefu, director of the China Organ Donation Committee and former vice-minister of health, made the remarks on Tuesday on the sidelines of the ongoing two sessions.
"By doing that, organs from death-row inmates used for life-saving operations are secured in a fair, transparent, and corruption-free manner," he said.
Previously, organ donations from executed prisoners were handled inappropriately by "some doctors and law enforcement officers", which might lead to malpractice and corruption, he said.
To end that, "we will regulate the issue by including voluntary organ donations by executed prisoners in the nation's public organ donation system to help ensure an open and fair practice", he said.
China launched the system in 2010 to make it easier for the public to donate organs and ensure the organs are given based on need rather than the "highest bidders".
As of Sunday, 1,570 organ donations had been facilitated via the system, according to Huang.
Donations from executed prisoners were initially not covered by the system. Zhu Jiye, director of the liver and gallbladder surgical department of Peking University People's Hospital, called for changes to the system, to ensure that death-row inmates are not coerced into donating organs.
"We respect their right to donate, but it must be voluntary and their donated organs should be used fairly," he said.
According to Zhu, transplant surgery using organ donations from death-row inmates has declined in recent years, and there were only two such operations at his hospital last year.
Huang added: "China is gradually moving away from a long-term reliance on executed prisoners as a major source for organ donations."
In November, 38 out of the 165 transplant centers in China signed a declaration vowing to stop using donated organs from executed prisoners, according to Huang.
He expects that procedures that include the procurement and allocation of organs from inmates who have been executed will be integrated into the national system soon.
"We've reached consensus with the legal and law enforcement departments on that," he said.
To ensure that donations are voluntary, written consent from the inmate and the family is required, he said.
Another source who didn't want to be named but is close to the situation said written consent from the executed prisoner's lawyer will be added as well.
Also, only designated organ procurement organizations will be allowed to approach law enforcement departments regarding the issue, Huang said.
Most importantly, "donated organs from executed prisoners will be put into a computerized system to ensure fair allocation", he said.
"Any organ donations, including those by executed prisoners, have to go through the system and the computerized allocation process," he added.
Statistics from the National Health and Family Planning Commission show that about 300,000 Chinese people need organ transplants every year.
However, only around 10,000 eventually receive one.
