Are transplants too scarce, or not scarce enough? A surprising debate about India

 India, now the most populous country in the world, does the third highest number of kidney transplants in the world (although their rate of transplantation per million population is quite low).  So transplants are nevertheless very scarce in India compared to the need, which is the situation worldwide.

Earlier this year, however, a paper by three veteran (non-Indian) transplant professionals who have headed large organizations expressed repugnance for the volume of transplants in India, and the fact that it depends mostly on living donor transplantation (LDT), suggesting it can be viewed as "both alarming and reprehensible."  Their paper's title makes it clear how they view it. 

Domínguez-Gil, Beatriz, Francis L. Delmonico, and Jeremy R. Chapman. "Organ transplantation in India: NOT for the common good." Transplantation 109, no. 2, February, 2025: 240-242. 

"The field of organ transplantation has evolved very differently across the world under the influence of different national healthcare financing systems. Healthcare is, in most countries, financed by taxation and thus through governmental budgets, in combination with private funds, mostly through contributory health insurance systems (eg, Australia, Canada, Europe, New Zealand, South America, and the United States). But across much of Asia, tertiary healthcare services, such as transplantation, are almost entirely dependent on the private finances of individuals. The impressive growth in Indian organ transplantation has been accomplished in for-profit hospitals, which have expanded Indian transplantation into 807 facilities, mostly associated with the major corporate hospital chains.6 Organ transplantation, in a part of the world where one-fifth of all people live, is thus largely not for the common good, but a treatment available for those with ample monetary resources." 

########## 

 This was followed by a firm rebuttal by distinguished Indian transplant professionals.  Their title makes their view equally clear:

Rela, Mohamed, Ashwin Rammohan, Vivek Kute, Manish R. Balwani, and Arpita Ray Chaudhury. "Organ Transplantation in India: INDEED, for the Common Good!." Transplantation 109, no. 6 (2025): e340-e342. 

 "We were deeply concerned by the article “Organ Transplantation in India: NOT for the Common Good” by Domínguez-Gil et al,  which we felt provided an unfairly critical view of the current state of organ transplantation in India. We aim to provide a point-by-point rebuttal based on actual figures and ground-reality rather than tabloid-press articles as cited by the authors.
 

"It is true that in the past 5 y, there has been an extraordinary growth in the number of transplantations in India (more than those achieved over several decades by European countries). While it is natural to be wary of this astronomical increase in transplant numbers, the authors’ assumption that this growth is likely nefarious reflects an outdated western mindset, rather than a true understanding of over 2 decades of massively coordinated effort by the Government of India, transplant professionals and all other stakeholders in the country. 

...

" The development of LDT has been presented with a negative connotation. This shows a scant understanding of the geo-socio-political idiosyncrasies prevalent in the Asian region, and unlike the west, its conventional dependence on LDT.

 ...

"The authors have further confused LDT and deceased donor transplantation with regards to foreigners having access to organs in India. The authors’ accusation of deceased donor organs being preferentially allocated to foreigner is presumptuous at best. The current organ allocation system under the aegis of the Government of India and state-wise organ transplant governing bodies is a very transparent process—and is reserved for Indian nationals.

...

" Transplant tourism being equated with organ commerce is erroneous, the authors’ fail to understand that many poor countries find India a more financially viable destination to get a transplant than countries in the west. Even affordable Governments in the middle east are moving to the east for transplantation, where the ministries have a direct tie-up with transplant units. 

"While it should be conceded that transplantation in India may not be available to all, true social upliftment necessitates broader initiatives beyond just immediate transplant availability: that of addressing poverty. Nonetheless, access to transplants for the underprivileged has greatly improved over the past decade. There are several public sector hospitals in the country that routinely provide transplantation services. In 2023, in the state of Tamil Nadu, 35.1% of all deceased donor renal transplants were performed for free in public sector hospitals (Table 1). 5 While traditionally, the private pay-from-pocket healthcare has been only for those with the resources, the central and several state governments (Tamil Nadu, Andhra Pradesh, Gujarat, etc) sponsor an all-inclusive healthcare state insurance for the poor, which includes transplantation at any approved private hospital in the state; which includes LDT.

I'm on my way to a conference in Cairo that is motivated in part by concern that healthcare in low and middle income countries has been impeded by some of the international healthcare organizations' lack of understanding or empathy for their situations. 

International Transplant Week in Egypt, 2025

 I'm preparing to spend next week in Cairo at the Donate Life Egypt 2025 International Transplant Week, where I'll give a talk on Thursday.  But much of my preparation is for Wednesday, when something potentially much more exciting is scheduled.

 

 

Wednesday (Nov. 12) will be devoted to an attempt to reach a new Global Consensus on Emerging Ethical Frontiers in Transplantation: Innovations & Global Collaboration

I'll be involved in Working Group 4: Ethical Frameworks for Regulated International Collaboration

Visualizing single versus multi-center kidney exchange: Dr. Vivek Kute

  Dr. Vivek Kute is the transplant nephrologist at one of the most active single-center kidney exchange programs in the world.  When he spoke on Thursday at Stanford's conference on extending kidney exchange, he used the slide below to help illustrate how India's move to multi-hospital kidney exchange (also  called kidney paired donation, KDP) would change the opportunities to find compatible living donor kidney transplants (LDKT)...

Kidney and liver exchange in India

 Here's an update from Dr. Vivek Kute and his colleagues on kidney and liver exchange in India.

Kute, V. B., Patel, H. V., Banerjee, S., Aziz, F., Godara, S. M., Bansal, S. B., ... & Srivastava, A. (2025). Analysis of kidney and liver exchange transplantation in India (2000–2025): a multicentre, retrospective cohort study. The Lancet Regional Health-Southeast Asia, Volume 37, June 2025, 100597. 

One Nation One Swap: National kidney exchange in India

 In India, the National Organ and Tissue Transplant Organization (NOTTO) wrote this week to all the State organizations (the SOTTOs) announcing the plan to form a nationwide kidney exchange program, called the "Uniform One Nation One Swap Transplant Program."

This has been the work of many people for a long time.  Of particular importance has been and will continue to be Dr. Vivek Kute from IKDRC Ahmedabad

 Here's the story in the Hindustan Times.

 NOTTO writes to states, UTs to implement swap organ transplant

Here's the letter itself:

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:

"Policy language: We suggest stepwise progress to achieve multicentre, regional, State and then a National program. Ideally, there should be engagement by the National Organ & Tissue Transplant Organization and the World Health Organization. 

While we recommend simultaneous surgery for mDRPs in a single exchange, sometimes logistical aspects have necessitated non-simultaneous exchanges"

 Wednesday, September 18, 2024 More on non-anonymous kidney exchange in India

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.)
