Practical market design makes policy recommendations (which can violate NBER publication policy)

The National Bureau of Economic Research (NBER) publishes a widely read series of working papers, before publication in refereed journals. They also distribute a list of papers that have been published in medical journals, since those journals don't allow prepublication in working papers.  For both these series the NBER has a rule against papers that make policy recommendations.

This is sometimes a problem for the field of market design, since practical market design is about finding ways to improve the operation of markets, which is a kind of policy advice. I encountered this recently with the two papers described below, published in medical journals, which apparently are too policy related: the policy being to save more lives by arranging more transplants, in this case of hearts and kidneys respectively. (Medical journals have their own conventions, but aren't opposed to advice on medical practice...)

I received the following email from the NBER, accompanied by a line of explanation for each paper.

The email began:

"I apologize for my belated response about your journal articles; while the subject matter is clearly vital, after review of the full-text, we determined that your articles make policy recommendations that are too specific for NBER’s policy on working papers (which we apply to papers in the article list)."

 It then continued by highlighting the offending sentences in each article:

More on non-anonymous kidney exchange in India

 Here's some further description of how kidney exchange is conducted in India without authorization* to use nondirected donors (so that all exchanges are conducted in cycles, i.e. in the absence of chains of exchange).

Vivek B. Kute, Himanshu V Patel, Subho Banerjee,Divyesh P Engineer, Ruchir B Dave, Nauka Shah, Sanshriti Chauhan ,Harishankar Meshram , Priyash Tambi  , Akash Shah, Khushboo Saxena,Manish Balwani , Vishal Parmar, Shivam Shah, Ved Prakash ,Sudeep Patel, Dev Patel, Sudeep Desai, Jamal Rizvi , Harsh Patel, Beena Parikh, Kamal Kanodia, Shruti Gandhi, Michael A Rees,  Alvin E Roth,  Pranjal Modi “Impact of single centre kidney-exchange transplantation to increase living donor pool in India: A cohort study involving non-anonymous allocation,”Nephrology, September 2024, https://onlinelibrary.wiley.com/doi/10.1111/nep.14380  

"In India, 85% of organ donations are from living donors and 15% are from deceased donors. One-third of living donors were rejected because of ABO or HLA incompatibility. Kidney exchange transplantation (KET) is a cost-effective and legal strategy to increase living donor kidney transplantation (LDKT) by 25%–35%.

"3.3 Non-anonymous allocation

"The THOA*, which regulates KET in India, is silent on the need for anonymity, so there is no legal requirement for anonymity in India, as compared with other countries, such as the Netherlands and Sweden. Our experience was that 90% of iDRP [incompatible Donor-Recipient Pairs] requested the opportunity to meet their matched donor and recipient pair (mDRP) and 10% asked the treating physician to decide if they should meet. None of the iDRP requested anonymity. Therefore, we have practiced absolute non-anonymity, meaning that all mDRPs meet and share medical reports after a potential exchange is identified, but before the formal allocation of pairs. If an iDRP requests anonymity, we would be willing to accommodate them, but to date, none have done so.

"Upon meeting with their mDRP, the iDRP can refuse the proposed exchange option without reason and continue to be on the waitlist and active in the KET pool. iDRPs must complete transplant fitness and legal documents required for transplant permission from the health authority before they are given the opportunity to meet their mDRP. A meeting between mDRPs occurs in the presence of a transplant physician, who can help solve any query before the proposed match is accepted by the involved pairs. iDRP are introduced to their mDRP prior to scheduling transplants to avoid chain collapse due to iDRP refusal of the mDRP. The mDRP shares medical reports of donors with each other, can also discuss with their other family members, and consults with their family physician/nephrologist before deciding whether to proceed. Living kidney donors are fully informed of perioperative and long-term risks before making their decision to donate. In India, donor age group matching is most commonly expected for all iDRP in the KAS."

Kidney Paired Donation in Developing Countries: a Global Perspective

*Here's the THOA, THE TRANSPLANTATION OF HUMAN ORGANS AND TISSUES ACT, 1994

Kidney Paired Donation in Developing Countries: a Global Perspective

 Vivek Kute and his colleagues argue that one of the lessons from the developing world is that kidney exchange can save many lives, but may need to be organized differently in some ways than in the developed world.

Kidney Paired Donation in Developing Countries: a Global Perspective by Vivek B. Kute, Vidya A. Fleetwood, Sanshriti Chauhan, Hari Shankar Meshram, Yasar Caliskan, Chintalapati Varma, Halil Yazıcı, Özgür Akın Oto & Krista L. Lentine, Current Transplantation Reports (2023)  (here's a link that may provide better access]

Abstract

...

"Despite the advantages of KPD programs, they remain rare among developing nations, and the programs that exist have many differences with those of in developed countries. There is a paucity of literature and lack of published data on KPD from most of the developing nations. Expanding KPD programs may require the adoption of features and innovations of successful KPD programs. Cooperation with national and international societies should be encouraged to ensure endorsement and sharing of best practices.

Summary

KPD is in the initial stages or has not yet started in the majority of the emerging nations. But the logistics and strategies required to implement KPD in developing nations differ from other parts of the world. By learning from the KPD experience in developing countries and adapting to their unique needs, it should be possible to expand access to KPD to allow more transplants to happen for patients in need worldwide."

...

" Despite the advantages of KPD programs, they remain rare in the developing world, and the programs that exist have many differences with those of developed countries. Program structure is one of these differences: multi-center, regional, and national KPD programs (Swiss, Australia, Canada, Dutch, UK, USA) are more common in the developed than the developing world, whereas single center programs are more common

...

"kidney exchanges frequently take weeks to months to obtain legal permission in India despite the fact that only closely-related family members (i.e., parents, spouse, siblings, children, and grandparents) are allowed to donate a kidney [47].

...

"Protecting the privacy of a donor, including maintaining anonymity when requested, is common practice among developed countries but uncommon in developing nations. Anonymous allocation during KPD is a standard practice in the Netherlands, Sweden, and other parts of Europe, but this is not the case in countries such as India, Korea, and Romania [14, 48, 49]. In areas where anonymity is not maintained, the intended donor/recipient pair must meet and share medical information once a potential exchange is identified, but before formal allocation of pairs occurs. The original donor/ recipient pair may refuse the proposed exchange option for any reason and continue to be on the waitlist. In India, nonanonymous KPD allocation is standard practice and has the goal of increasing trust and transparency between the transplant team and the administrative team [14, 49]. Countries differ in philosophical approaches to optimizing trust and transparency, and objective data on most effective practices would benefit the global community."

Tomorrow I hope to have a few words to say about the equally unique situation in China.

Organ transplantation in China: in transition--and controversy about paying funeral costs

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.)

The Dr H.L. Trivedi Oration at the Indian Society of Transplantation (ISOT) Meeting 2022

Here's the meeting announcement:

ISOT 2022 NAGPUR

32^nd Annual Conference of The Indian Society of Organ Transplantation
2^nd Mid-term Meeting of Liver Transplantation Society of India
15^th Annual International Conference of NATCO
Dates : 12^th - 16^th October 2022 | Venue : Hotel Le Meridien, Nagpur

My talk, the Dr H.L. Trivedi Oration   is scheduled for 11:00am on Friday the 14th in Nagpur, which means I'll be giving it by zoom tonight, Thursday evening at 10:30 pm Pacific Time.

The presentation, which  will be about "Increasing the availability of transplants in India" is in honor of the late Dr. Hargovind Laxmishanker "H. L." Trivedi (August 1932 – October 2019), who I had the privilege of meeting,

Here's his obituary : 

Kute, Vivek, Himanshu Patel, Pankaj Shah, Pranjal Modi, and Vineet Mishra. "Professor Dr. HL Trivedi pioneering nephrologist and patriot who cared for his country (31-08-1932 TO 2-10-2019)." Indian Journal of Nephrology 29, no. 6 (2019): 379.

*********

Here's my concluding slide:

• India has enormous talent and accomplishment in living-donor transplantation
• To more nearly reach it’s potential, India needs to invest in recovering deceased donor organs.
• In the near term, it can build on it’s accomplishments in kidney transplantation, by 
• establishing national (not just regional) kidney exchange
• Continuing to explore international exchange for the hardest to match pairs
• Reducing restrictions on who can be an exchange donor
• Allowing non-directed donors and chains
• Allowing some chains to begin with a deceased-donor kidney
• Reducing financial barriers by increased investment in public hospitals and government health insurance, for organ donors as well as recipients

TTS2022 Awards--Congratulations

 Today at TTS2022, prizes will be awarded.  One that I know is very well deserved, is to Dr. Vivek Kute, for his extraordinary achievements in kidney transplantation in India. Congratulations to all the prize winners.

I've followed Dr. Kute's work over the years in multiple posts.

Kidney exchange in India: progress, then Covid

 Here's a paper reporting, among other things, a long kidney exchange cycle in India.  But Covid has put a temporary halt to all that.

But now Covid is taking a toll. Dr. Kute writes in an email that transplantation has been on hold in Gujarat since April. He says "we had cumulative 225 kidney transplant recipients with PCR confirmed COVID-19 in our single center. Over all mortality in transplants population 10% and much higher in dialysis."

Here's hoping that vaccine production ramps up and Covid falls away in India and the rest of the world soon.

I have quite a number of posts following the work of Dr. Kute and his colleagues in Ahmedabad.

Non-Simultaneous Kidney Exchange Cycles in India: new design, in Transplant International by Kute and Rees et al.

 Perhaps the biggest part of the ongoing design of kidney exchange around the world involves adapting to constantly changing local conditions in patient and donor populations, and the prevailing laws, regulations and medical situation.  In India, where non-directed donation is illegal (except in Kerala), this means that some patients can be transplanted only if long exchange cycles are possible.  In most of the world, the requirement that the surgeries in a cycle be performed simultaneously has prevented this.

The paper below, organized by two of the world's most innovative transplant doctors, Vivek Kute and Mike Rees (first and last authors, in the medical manner), demonstrates a path forward in India. The paper reports 17 very carefully arranged and conducted non-simultaneous (and non-anonymous) kidney exchange cycles, accomplishing 67 transplants. These were performed at the  Trivedi Institute of Transplantation Sciences  (using our software:).

Vivek B. Kute, Himanshu V. Patel, Pranjal R. Modi, Sayyad J. Rizvi, Pankaj R. Shah, Divyesh P Engineer, Subho Banerjee, Hari Shankar Meshram, Bina P. Butala, Manisha P. Modi, Shruti Gandhi, Ansy H. Patel, Vineet V. Mishra, Alvin E. Roth, Jonathan E. Kopke, Michael A. Rees, “Non-simultaneous kidney exchange cycles in resource-restricted countries without non-directed donation,” Transplant International, February 2021.

Abstract: Recent reports suggest that bridge-donor reneging is rare (1.5%) in non-simultaneous kidney exchange chains. However, in developing countries, the non-directed donors who would be needed to initiate chains are unavailable, and furthermore, limited surgical space and resources restrain the feasibility of simultaneous kidney exchange cycles. Therefore, the aim of this study was to evaluate the bridge-donor reneging rate during non-simultaneous kidney exchange cycles (NSKEC) in a prospective single-center cohort study (n=67). We describe the protocol used to prepare co-registered donor-recipient pairs for non-simultaneous surgeries, in an effort to minimize the reneging rate. In addition, in order to protect any recipients who might be left vulnerable by this arrangement, we proposed the use of standard criteria deceased-donor kidneys to rectify the injustice in the event of any bridge-donor reneging.  We report 17 successful NSKEC resulting in 67 living-donor kidney transplants (LDKT) using  23 bridge-donors without donor renege  and  no intervening pairs became unavailable. We propose that NSKEC could increase LDKT, especially for difficult-to-match sensitized pairs (25 of our 67 pairs) in countries with limited transplantation resources. Our study confirms that NSKEC can be safely performed with careful patient-donor selection and non-anonymous kidney exchanges.

Kidney exchange in India: the legal framework

Robot-assisted kidney transplantation in Ahmedabad, India.

Long kidney exchange in Ahmedabad, India

Vivek Kute writes with the news:
IKDRC completes India’s longest cross-transplant chain

"Institute of Kidney Diseases and Research Center, Institute of Transplantation Sciences (IKDRC-ITS) Ahmedabad, India is pleased to share the news of an exciting milestone for the patients with end stage renal disease with incompatible living kidney donors. Our transplant team has completed longest Kidney Exchange transplant chain in India as well as Asia involving 10 donor-recipients pairs over 5 days in January 2020. Two kidney transplant surgeries were performed each on 4, 6 and 7 January, 3 transplants on 8 January and last kidney transplant was completed on 22 January 2020.
...
". The success of this program can be attributed to the selflessness of the more than 500 family members who have stepped forward to be living organ donors. Dr Vivek Kute Professor of Nephrology maintains the single center registry of incompatible pairs. Dr Vivek Kute  and his team is greatful to Prof. Michael Rees and Prof. Alvin Roth for providing the Alliance for Paired Donations software for computer allocation at free of cost. Transplant team members are Dr Vineet Mishra, Dr Pranjal Modi, Dr Himanshu Patel, Dr Jamal Rizvi, Dr Vivek Kute, Dr Bina Butala and others."

Kidney exchange in India: the legal framework

Last week in Ahmedabad I had a chance to interact with Dr. Vivek Kute and his colleagues at the Trivedi Institute, to better understand the setting of their innovative kidney exchange program.  The legal framework is of course a big part of that environment.

Here's India's Transplantation of Human Organs and Tissues Act (THOA), 2014 (scroll down for the English language version).

As in other places, much of the law is shaped by  repugnance towards kidney sales. To this end, the law requires that an Authorisation Committee approve donation from someone who is not a "near relative," in the immediate nuclear family.

"Authorisation Committee.
(3) When the proposed donor and the recipient are not near relatives, the Authorisation Committee shall,- 
(i)evaluate that there is no commercial transaction between the recipient and the donor and that no payment has been made to the donor or promised to be made to the donor or any other person; 
(ii)prepare an explanation of the link between them and the circumstances which led to the offer being made;"

In the case of kidney exchange, only a near relative may serve as the intended donor (i.e. no uncles, aunts, cousins, etc.).

"(4)Cases of swap donation referred to under subsection (3A) of section 9 of the Act shall be approved by Authorisation Committee of hospital or district or State in which transplantation is proposed to be done and the donation of organs shall be permissible only from near relatives of the swap recipients."

The present law also does not allow nondirected donors.

Abstract: "Kidney exchange transplantation is well established modality to increase living donor kidney transplantation. Reasons for joining kidney exchange programs are ABO blood group incompatibility, immunological incompatibility (positive cross match or donor specific antibody), human leukocyte antigen (HLA) incompatibility (poor HLA matching), chronological incompatibility and financial incompatibility. Kidney exchange transplantation has evolved from the traditional simultaneous anonymous 2-way kidney exchange to more complex ways such as 3-way exchange, 4-way exchange, n-way exchange,compatible pair, non-simultaneous kidney exchange,non-simultaneous extended altruistic donor, never ending altruistic donor, kidney exchange combined with desensitization, kidney exchange combined with ABO incompatible kidney transplantation, acceptable mismatch transplant, use of A2 donor to O patients, living donor-deceased donor list exchange, domino chain, non-anonymous kidney exchange, single center, multicenter, regional, National, International and Global kidney exchange. Here we discuss recent advances in kidney exchanges such as International kidney exchange transplantation in a global environment, three categories of advanced donation program, deceased donors as a source of chain initiating kidneys, donor renege myth or reality, pros and cons of anonymity in developed world and (non-) anonymity in developing world, pros and cons of donor travel vs kidney transport, algorithm for management of incompatible donor-recipient pairs and pros and cons of Global kidney exchange. The participating transplant teams and donor-recipient pairs should make the decision by consensus about kidney donor travel vs kidney transport and anonymity vs non-anonymity in allocation as per local resources and logistics. Future of organ transplantation in resource-limited setting will be liver vs kidney exchange, a legitimate hope or utopia?"

An interesting section of the paper discusses different practices regarding anonymity in kidney exchange centers in different countries:

"PROS AND CONS OF ANONYMITY IN DEVELOPED WORLD AND (NON-) ANONYMITY IN DEVELOPING WORLD

There is disparity on standard practice of kidney exchange in developed and developing World in term of (non-) anonymity. There is variable practice on anonymity before and after surgery in different countries.

Conditional approach[38]: When the donor-recipient pairs give consent for meeting after surgery, they are allowed to meet each other after surgery in some countries such as the United States of America[39] and the United Kingdom[40]. In other countries, such as the Netherlands and Sweden[41], anonymity is absolute. Anonymity protects patients, donors and transplant hospital/ administration against the risks of revoking anonymity and prevents further commercialization of organs, and breach of patient donor privacy. An Ethical, Legal and Psychosocial Aspects of Organ Transplantation (ELPAT), a subsection of the European Society for Organ Transplantation reported that a conditional approach to anonymity should be possible after surgery[42]. Pronk et al[38] showed that most donor-recipient pairs who participated in anonymous donation process are in favour of a conditional approach to anonymity. Guidelines on how to revoke anonymity if both parties agree are needed and should include education about pros and cons of (non-) anonymity and a logistical plan on how, when, where, and by whom anonymity should be revoked.

Non-anonymous allocation[11,12]: Donor-recipient pairs are allowed to meet each other before allocation of donor for surgery and even after surgery. They can share medical reports of exchange donors before surgery and kidney transplant and donor surgery outcome after surgery. Donor-recipient pairs do not choose their match but donor-recipient pairs may decline a match or can withdraw from participation in the kidney exchange program at any time, for any reason. Non-anonymous allocation has the potential of commercialization of organs in case of compatible donor-recipient pairs along with breach in privacy of donor-recipient pairs. Kute et al[11,12] reported that donor-recipient pairs are willing for non-anonymous allocation process in single center study of 300 kidney exchange transplants in India. They reported that non-anonymity is more helpful in manual allocation in absence of computer software allocation which also increases trust between patients, donors and transplant hospital/administration and legal team. More long term prospective studies are required to explore the donor and recipient perspective on anonymity in living kidney donation in different socio-economic regions and countries."

Regarding Global Kidney Exchange they conclude:

"Global kidney exchange appears to provide life-saving kidney transplantation to poor donor-recipient pairs from developing countries that otherwise could die due to economic constrain[50-53]."

And here's their conclusion:

CONCLUSION

"Kidney exchange transplantation has increased living donor kidney transplantation for end stage renal disease patients with chronological incompatibility and financial incompatibility. The participating transplant teams and donor-recipient pairs should make the decision by consensus about kidney donor travel vs kidney transport and anonymity vs non-anonymity in allocation as per local resources and logistics. There is need of uniform algorithm for management of incompatible donor-recipient pairs."
