As I have tried to show in my preceding posts on this Blog, the organ transplantation industry in fraught with medical/moral problems.  The first heart transplant by Dr. Christiaan Barnard in South Africa in 1967 caused the medical profession to hold the infamous Harvard meeting in 1968 at which it was decided that “brain death” was sufficient to declare a person dead and to harvest a person’s organs while the body was actually still alive.  In the article below published in the New England Journal of Medicine in August, 2013, by Drs. Ladin and Hanto, they described the problem of obtaining lungs for transplantation in pediatric patients.  Their article was challenged in the current issue of NEJM  by Dr. Thomas Egan and defended by Drs. Ladin and Hanto.  Obviously the problem of obtaining donor lungs for pediatric patients involves moral questions in addition to the scientific aspects of such transplantation.

Rationing Lung Transplants — Procedural Fairness in Allocation and Appeals

Interview with Dr. Keren Ladin on fairness in the allocation of lung transplants for children. (14:03) .

Organ transplantation requires explicit rationing and relies on public trust and altruism to sustain the organ supply. The well-publicized cases of two pediatric candidates for lung transplants have shaken the transplant community with emergency legal injunctions arguing that current lung-allocation policy is “arbitrary and capricious.” Although the resulting transplantation seemingly provided an uplifting conclusion to an emotional public debate, this precedent may open the floodgates to litigation from patients seeking to improve their chances of obtaining organs. These cases questioned the potential disadvantaging of children and the procedural fairness in lung allocation. But legal appeals exacerbate inequities and undercut public trust in the organ-transplantation system.

The controversy began when the parents of Sarah Murnaghan, a critically ill 10-year-old awaiting a lung transplant for cystic fibrosis, appealed through her physicians to the Organ Procurement and Transplantation Network (OPTN) for an exception to the policy that restricts lung-transplant candidates younger than 12 years to receiving organs from donors younger than 12. When this appeal failed, the Murnaghans appealed to the media, politicians, and finally a federal judge to grant access to the larger pool of lungs from adult donors. They argued that mistreatment of pediatric candidates for transplants would probably result in Sarah’s death. The merits of the case were never argued, since during the 10-day temporary injunction, Murnaghan received two lung transplants from adult donors. She has had serious complications, including pneumonia, and required a tracheostomy. .

In 2005, to improve equity and efficiency, the OPTN switched from prioritization based on waiting time, a first-come–first-served approach that often prioritized less-urgent cases for organs, to an approach that incorporated consideration of urgency. After a 5-year review, the OPTN had developed a lung allocation score (LAS) using medical factors that predict disease severity and the likelihood of dying on the waiting list.1 Such scores were assigned only to patients 12 or older, because there were insufficient data to support their applicability to younger populations, owing to their different diagnoses and limited outcomes data. Thus, patients younger than 12 were excluded from consideration for adolescent and adult donors’ lungs (which are allocated according to the LAS and geography) and limited to use of pediatric donors’ lungs, which are allocated according to two priority levels (different degrees of urgency based on medical criteria) and geography. . The LAS policy has increased lung-transplantation rates and reduced mortality on the waiting list among older patients.2

Pediatric patients, however, continue to have higher waiting-list mortality and are less likely to receive transplants (see graphsUnadjusted Relative Risk of Dying While on the Waiting List or Becoming Too Sick to Receive a Lung Transplant (Panel A) and Relative Likelihood of Receiving a Lung Transplant (Panel B), According to Age Group, September 12, 2010 to March 11, 2013.), despite wider geographic sharing of pediatric organs and the use of urgency levels — primarily because there are few pediatric donors. The supporters of the “under-12 rule” argue that it promotes equity and efficiency because of its aggregate benefits. They also cite the problematic discrepancy in lung size between adult donors and pediatric recipients. Furthermore, as a treatment for cystic fibrosis (the most common diagnosis among pediatric candidates for lung transplants), transplantation has been shown in several retrospective studies to have only marginal benefit, owing to improvements in medical management (although some data suggest otherwise).3 Lung transplantation in pediatric patients is also associated with high postoperative morbidity and mortality, largely because of the recipients’ underlying diagnoses. .

Nevertheless, appeals to list children for adult organs have merit. First, designating age 12 as the cutoff arbitrarily disadvantages some children because age is a poor proxy for size. Younger patients who meet the size requirements and could benefit from adult lungs should be considered eligible. Second, in allocating other organs, we often prioritize children, partly on the basis of “fair innings” considerations (equalizing people’s chances of living until a given age) and partly because of the unique importance for physical and cognitive development that a transplant may confer. These arguments also apply to lung transplantation. Third, transplanting lungs into children is similarly efficient to doing so in adults, since their graft-survival rates are similar. Lobar resection can facilitate transplantation of adult lungs into smaller pediatric patients — also with similar results.4 Finally, given the scarcity of pediatric lung transplants, the data necessary for optimal validation of the LAS in this population may never be available. Without conclusive data, we should err on the side of inclusion, not exclusion from access to a broader supply of lifesaving organs. Currently, only 30 children in the United States await lung transplants, and only 11 of them are 6 to 11 years of age. The change that would occur by allowing these children access would most likely have little effect on nonpediatric candidates. .

In response to objections that children are unfairly disadvantaged, the OPTN will review its lung-allocation policy during the next year and allow expedited appeals to an expert lung-allocation board in the interim. Candidates approved during this period will gain access to the full pool of lungs on the basis of the LAS and geographic location, while maintaining their pediatric priority. . Are the organ-allocation and appeals processes fair? Despite this case, we believe they are. An ethical framework that is gaining traction in health policy, Accountability for Reasonableness (A4R), offers an approach for achieving fairness and legitimacy in allocating health resources.5 A4R requires transparency about the objectives of and evidence for decisions, consensus about the relevance of rationales used in resource allocation, a process for reevaluating and revising criteria in light of new evidence, and procedures for enforcing these conditions in the deliberative process. This approach claims that a fair deliberative process results in outcomes that are acceptable to all. .

A4R has limitations in Murnaghan’s case, including those resulting from the limited data regarding lung-transplantation outcomes in the pediatric population. But generally, organ allocation follows A4R’s tenets: it is public, transparent, revisable, enforceable, and open to appeals, and it incorporates key stakeholders. Organ-allocation algorithms seek to balance equity and efficiency. Committees comprising medical and ethics experts, transplant recipients and donors, and other key stakeholders meet in a predictable and transparent way. They deliberate and issue reports and policy recommendations that are opened to public comment. Policies are enforced and revised regularly on the basis of new evidence. .

Transplant candidates and their families go to great lengths to obtain lifesaving treatment. They should be assured of fair process and, in cases of error or newly available information, allowed to appeal decisions. Appeals waged through federal courts and the court of public opinion, however, undermine fairness. Judicial appeals grant discretionary access to wealthier people, exacerbating disparities and discrimination. Moreover, appeals are inefficient, complicating allocation and leading to longer allocation times, poorer matches due to expansion of criteria, and greater difficulty in managing the waiting list. Lawsuits also inappropriately saddle courts with decisions about health policy. Finally, appeals reduce transparency and predictability, undermining the public perception of fairness, which could reduce donation rates. . Although the OPTN’s allowance of appeals to an expert panel is preferable to judicial appeals, it is problematic. Relying on physicians to appeal on behalf of candidates leaves patients of lower socioeconomic status, those less informed about their options, and those lacking advocates vulnerable to worse treatment. Physicians may also fear that accepting the responsibility of mounting appeals means assuming greater risk of poor outcomes and subsequent audits, which may also result in disparities. .

To prevent unequal treatment, absent better data, we believe the OPTN should expand its policy to automatically assign an LAS to pediatric candidates and put those meeting the size and LAS criteria for adult and adolescent organs on the waiting list. Lung transplants should be allocated on the basis of the LAS and size match, with consideration of lobar resection for small recipients of adult lungs. Children should retain preference for lungs from pediatric donors. . Overall, we believe that the organ-allocation process is fundamentally fair, in part because of procedures in place to revise and modify allocation. It is because of this fair process that errors can be discovered and addressed. Our proposed changes would provide more lifesaving lungs to children; they would also provide useful data for the 1-year policy review and could ensure equal treatment for all children awaiting lung transplants. .

In their Perspective article, Ladin and Hanto (Aug. 15 issue)1 misrepresent the lung-allocation policy of the Organ Procurement and Transplantation Network (OPTN) by stating that candidates younger than 12 years of age are restricted to receiving lungs from donors younger than 12 years of age. In fact, within each organ procurement organization (OPO), lungs from donors younger than 18 years of age must be made available to all pediatric patients before being made available to adults. Children younger than 12 years of age may receive lungs from adult donors if the lungs are declined by adolescents and adults.2 . Ladin and Hanto ignore critical references. The decision to exclude children younger than 12 years of age from receiving allocation scores was based on careful data review3; it did not result from insufficient data. Cystic fibrosis is indeed “the most common diagnosis among pediatric candidates” — but not among children younger than 12 years of age. This is another reason why calculating an allocation score was difficult. Waiting time was retained as a criterion in this age group because of the diversity of diagnoses and limited information about the risk of death among these patients and the effect of these diagnoses on survival after transplantation. .

The authors propagate the misperception that there are too few pediatric donors of lung transplants for children. Each year, less than 10% of organ donors younger than 11 years of age provide lungs, as compared with more than 35% of adolescent organ donors (Table 1Table 1Pediatric Lung Donors, Patients on Waiting Lists, and Transplant Recipients in the United States, 2003–2012.). Nearly 30% of lungs from donors younger than 12 years of age are transplanted into adults (unpublished data from the OPTN). Thus, the reduced likelihood of transplantation in children 6 to 11 years of age cannot be ascribed solely to donor availability.4 We believe it results from a combination of geography and conservative pediatric transplantation programs. Finally, most children younger than 12 years of age are too small to receive lobar lung transplants from adult donors. In contrast to lobar liver transplants, lungs must fit into the thorax. Indeed, in the study by Marasco et al. cited by the authors, only 2 of the 23 recipients of lobar lung transplants were younger than 12 years of age. Thus, there is insufficient evidence to support changing allocation policy to encourage the increased use of lobar lung transplants from deceased donors in children. .

Instead of lobar transplantation, children younger than 12 years of age would be best served by broader geographic sharing of lungs through elimination of local OPO priority. This change would increase the likelihood that pediatric organs would be available to and transplanted into children. It would ensure that lungs are available to all candidates — pediatric and adult — and that they are best matched for size, urgency, and benefit, in contrast to the existing system in which local priority often prevents donor lungs in one place from being transplanted into a patient who has a higher allocation score and who lives in a nearby state. .

The authors reply:

The revised allocation policy has resulted in an uneven distribution of benefits and burdens. Pediatric candidates have a higher risk of dying while they are on the waiting list, and those 6 to 11 years of age have lower transplantation rates. . Our Perspective article accurately reflects the lung-allocation policy.1 Although transplantation of adult lungs into pediatric candidates is possible, it is rarely performed. Adults and adolescents are prioritized for those transplants. Adolescent lungs must be declined for adolescent candidates before they are made available to pediatric candidates. The small numbers of pediatric candidates and donors exacerbate the struggle to match need with availability. Furthermore, some pediatric candidates who are close to 12 years of age may be able to receive a small adult lung. At a minimum, these patients should be afforded this opportunity. We also suggest that the United Network for Organ Sharing (UNOS) review the rates at which organs are declined in children. . Egan and Sweet cite their own article, which contradicts their statement that sufficient data exist to exclude pediatric candidates from the use of the lung-allocation score (LAS). In that article, they state that “because of the small number of potential recipients younger than 12 years, risk factors for death cannot be reliably calculated with the available data.” This conclusion provides support for our article and the decision by UNOS to collect more data about the LAS in younger populations. . Egan and Sweet misconstrue our argument about lobar lung transplants. We do not advocate these as a general policy, but we support their use in certain circumstances, given evidence of good outcomes achieved by some programs. The patient described in our article, Sarah Murnaghan, is recovering at home because of such a transplant. Broader geographic sharing of lungs may increase the availability of pediatric lungs and should be examined, though potential gains should be weighed against the costs of longer ischemic time. .

The authors conflate potential and available organs. We support efforts to increase pediatric lung donation. However, UNOS policy must fairly allocate actual, not potential, organs. Fairness for pediatric candidates requires equal access to treatment. The exception afforded to Sarah Murnaghan should be extended to all children. .

  1. Your Excellency, I have a question on a completely unrelated topic. It would seem that the Church ought to threaten with excommunication those who vote specifically with the intention of plundering the rich by means of the graduated income tax. For St. Thomas Aquinas, in the Summa Theologica, (I, II, Q. 96, Art. 4) wrote that only laws that burden society “proportionately” are just. But the graduated income tax is inherently unjust; it is designed to soak the rich. Therefore those who specifically intend to support the graduated income tax with their vote ought to be so threatened. (This does not deny whatever sort of duty it is the rich have towards the Church and the poor.) St. Thomas Aquinas, in De Regno: to the King of Cyprus, wrote that a tyrant is worse than a slaver or slave-trader, because he enslaves everybody. St. Augustine declared that Alexander the Great was like a grand pirate. It also seems to me that any vote for a party that is left of center is intrinsically evil because it is a vote to increase the plundering of the richirrespective of any other reason, such as a pro-peace policy. Would you be so gracious as to offer your opinion? Thank you. Benjamin Warren
