Organ donation and utilization in the USA

The processes leading to donor identification, consent, organ procurement, and allocation continue to dominate debates and efforts in the field of transplantation. A considerable shortage of donors remains while the number of patients needing organ transplantation increases.
This article reviews the main trends in organ donation practices and procurement patterns from both deceased and living sources in the USA. Although there have been increases in living donation in recent years, 2002 witnessed a much more modest growth of 1%. Absolute declines in living liver and lung donation were also noted in 2002.
In 2002, the number of deceased donors increased by only 1.6% (101 donors). Increased donation from deceased donors provides more organs for transplantation than a comparable increase in living donation, because on average 3.6 organs are recovered from each deceased donor. The total number of organs recovered from deceased donors increased by 2.1% (462 organs). Poor organ quality continued to be the major reason given for nonrecovery of consented organs from deceased donors.
The kidney is the organ most likely to be discarded after recovery. Over the past decade the discard rate of recovered kidneys has increased from 6% to 11%. Many of these are expanded criteria donor kidneys.     

Incentivizing Authorization for Deceased Organ Donation With Organ Allocation Priority: The First 5 Years

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.     

The Life-Years Saved by a Deceased Organ Donor

Understanding the additional life-years given to patients by deceased organ donors is necessary as substantial investments are being proposed to increase organ donation. Data were drawn from the Scientific Registry of Transplant Recipients. All patients placed on the wait-list as eligible to receive or receiving a deceased donor solid organ transplant between 1995 and 2002 were studied. The benefit of transplant was determined by the difference in the expected survival experiences of transplant recipients and candidates expecting transplant soon. An average organ donor provides 30.8 additional life-years distributed over an average 2.9 different solid organ transplant recipients, whereas utilization of all solid organs from a single donor provides 55.8 additional life-years spread over six organ transplant recipients. The relative contribution of the different organs to the overall life-year benefit is higher for liver, heart and kidney, and lowest for lung and pancreas. The life-year losses from unprocured and unused organs are comparable to suicide, congenital anomalies, homicide or perinatal conditions and half that of HIV. Approximately 250,000 additional life-years could be saved annually if consent for potential deceased donors could be increased to 100%. Therefore, increasing organ donation should be considered among our most important public health concerns.     

Organ donation and utilization in the United States, 2004

This article discusses issues directly related to the organ donation process, including donor consent, donor medical suitability, non-recovery of organs, organs recovered but not transplanted, expanded criteria donors (ECD), and donation after cardiac death (DCD). The findings and topics covered have important implications for how to evaluate and share best practices of organ donation as implemented by organ procurement organizations (OPOs) and major donor hospitals in the same donation service areas (DSAs). In 2002 and 2003, US hospitals referred more than one million deaths or imminent deaths to the OPOs of their DSA. Referrals increased by nearly 10% from 2002 to 2003 (1,022,280 to 1,121,392). Donor consents have increased by about 5% and the number of total deceased donors has risen from 6,187 to 6,455. Since multiple organs are recovered from most donors, this increase allowed more than 500 additional wait-listed candidates to receive an organ transplant than in the prior year. Non-traditional donor sources have experienced a large rate of increase; in 2003 the number of ECD kidney donors increased by 8% and the number of DCD donors increased by 43% , from 189 donors in year 2002 to 271 donors in 2003.     

Organ Donation and Utilization, 1995–2004: Entering the Collaborative Era

Continued progress in organ donation will help enable transplantation to alleviate the increasing incidence of end-stage organ disease. This article discusses the implementation and effect of the federally initiated Organ Donation Breakthrough Collaborative; it then reviews organ donation data, living and deceased, from 1995 to 2004. It is the first annual report of the Scientific Registry of Transplant Recipients to include national data following initiation of the collaborative in 2003. Prior to that, annual growth in deceased donation was 2%–4%; in 2004, after initiation of the collaborative, deceased donation increased 11%. Identification and dissemination of best practices for organ donation have emphasized new strategies for improved consent, including revised approaches to minority participation, timing of requests and team design. The number of organs recovered from donation after cardiac death (DCD) grew from 64 in 1995 to 391 in 2004. While efforts are ongoing to develop methodologies for identifying expanded criteria donors (ECD) for organs other than kidney, it is clear DCD and ECD raise questions regarding cost and recovery. The number of living donor organs increased from 3493 in 1995 to 7002 in 2004; data show trends toward more living unrelated donors and those providing non-directed donations.     

Organ Donation and Utilization in the United States, 1996–2005

The success of clinical transplantation as a therapy for end-stage organ failure is limited by the availability of suitable organs for transplant. This article discusses continued efforts by the transplant community to collaboratively improve the organ supply. There were 7593 deceased organ donors in 2005. This represents an all-time high and a 6% increase over 2004. Increases were noted in deceased organ donation of all types of organs; notable is the increase in lung donation, which occurred in 17% of all deceased donors. The percentage of deceased donations that occurred following cardiac death has also reached a new high at 7%. The number of living donors decreased by 2%, from 7003 in 2004 to 6895 in 2005. This article discusses the continued efforts of the Organ Donation Breakthrough Collaborative and the Organ Transplantation Breakthrough Collaborative to support organ recovery and use and to encourage the expectation that for every deceased donor, all organs will be placed and transplanted.     

Deceased Organ Donation in Canada: An Opportunity to Heal a Fractured System

There has been no significant increase in the number of deceased organ donors in Canada over the past decade. Canada's donation and transplant system will be restructured with the formation of a new national organization to oversee activity in provincially governed donation and transplantation services. We review the current status of deceased organ donation, highlight issues contributing to the current stagnation in donation and identify changes that will enable success in a new Canadian system. Determining Canada's organ donation performance is difficult because the data required to calculate meaningful metrics of donation performance are not available. Canadians wait longer for transplantation than Americans, and Canada is falling further behind the United States primarily because of fewer donations after cardiac death. The ongoing divide between intergovernmental jurisdictional domains limits national initiatives to improve Canada's donation system. The success of a new national system will be enabled by uniform provincial legislation to ensure that all patients are offered the option to donate, commitment of resources to support organ donation by provincial governments, transparent reporting of comparable metrics of donation performance, establishment of processes to introduce and implement new initiatives and alterations to reimbursement models for organ donation and recovery.     

Organ Donation and Utilization in the United States: 1998–2007

Organ transplantation remains the only life-saving therapy for many patients with organ failure. Despite the work of the Organ Donation and Transplant Collaboratives, and the marked increases in deceased donors early in the effort, deceased donors only rose by 67 from 2006 and the number of living donors declined during the same time period. There continues to be increases in the use of organs from donors after cardiac death (DCD) and expanded criteria donors (ECD). This year has seen a major change in the way organs are offered with increased patient safety measures in those organ offers made by OPOs using DonorNet^©. Unfortunately, the goals of 75% conversion rates, 3.75 organs transplanted per donor, 10% of all donors from DCD sources and 20% growth of transplant center volume have yet to be reached across all donation service areas (DSAs) and transplant centers; however, there are DSAs that have not only met, but exceeded, these goals. Changes in organ preservation techniques took place this year, partly due to expanding organ acceptance criteria and increasing numbers of ECDs and DCDs. Finally, the national transplant environment has changed in response to increased regulatory oversight and new requirements for donation and transplant provider organizations.     

Present Data on Organ Donation and Transplantation in Poland

At present, organ transplantation activity in Poland is located in the middle among European Union countries. There are appropriate law regulations, well-organized legal structures, well-educated transplant teams, good transplantation results, and case registries. There are 24 organ transplant teams in 20 centers, including 46 programs. Since 1966, over 18,000 organs have been transplanted 14,300 kidneys; 1800 livers; 1700 hearts; 250 kidney/pancreases and 30 lungs. Every year almost 1500 organs are procured from about 500 cadaveric heart-beating donors (9–14 per million people [pmp]) with 50 from living donors: 800 to 1000 kidneys (21–28 pmp); over 200 livers (5–6 pmp); and 60 to 100 hearts (1.6–2.7 pmp). National transplant registries are maintained in Poltransplant including a central registry of refusals (the policy of presumed consent with registered objection on donation after death is implemented), waiting lists, a cadaveric and living donor registry, and a transplant registry. There are still some actions that should be undertaken to strengthen the transplantation system in Poland, to increase organ availability, to enhance the efficiency and accessibility of transplantation systems, and to improve quality and safety: namely, increasing deceased donations to their full potential, appointing transplant coordinators in every hospital where there is the potential for organ donation, promoting quality improvement programs, and promoting living donation.     

The European experience

This mini‐review on European experiences with tackling the problem of organ shortage for transplantation was based on a literature review of predominantly European publications dealing with the issue of organ donation from deceased donors. The authors tried to identify the most significant factors that have demonstrated to impact on donation rates from deceased donors and subsequent transplant successes. These factors include legislative measures (national laws and European Directives), optimization of the donation process, use of expanded criteria donors, innovative preservation and surgical techniques, organizational efforts, and improved allocation algorithms.     

Lack of impact of human leukocyte antigen matching in living donor kidney transplantation: experience at Akdeniz University

Lack of expansion of the deceased donor supply has resulted in a severe shortage of organs worldwide. Spousal donors are one possible alternative organ source for patients on the kidney transplant waiting list. Despite human lymphocyte antigen (HLA) matching between recipients and unrelated donors being poor, the reported survival rates for these grafts, including spouses, are comparable to those for grafts from living related donors and higher than those for deceased donor kidneys. In 2000, our renal transplantation program began accepting living donor-recipient pairs with one or zero HLA matches. The purpose of this study was to assess this policy for accepting living unrelated donors. The 3-year graft survival rates for the transplants from living unrelated donors were similar to that for transplants from living related donors (log-rank = 0.078). The number of HLA mismatches did not significantly influence the survival rates for either of these groups of living donor transplants. Multivariate analysis revealed that dialysis duration (P = .057) and recipient age (P = .066) negatively influenced patient survival in living donor kidney transplantation. The graft and patient survival rates for the donor transplantations were higher than those for deceased donor transplantations. In light of these findings and considering the increasing problem of organ shortage, we conclude that living unrelated kidney transplantation should be performed, with strict guidelines. Spousal donation is the most favorable form of living unrelated renal transplantation.     

Organ Donation and Transplantation Statistics in Belgium for 2012 and 2013

BackgroundThe 2012 and 2013 solid organ transplantation statistics were presented during the annual meeting of the Belgian Transplant Society.MethodsAll data presented were collected from Eurotransplant International Foundation and/or from all individual Belgian transplant centers.ResultsIt was demonstrated that the highest number of deceased donors detected (1310) from which 47.8% were an effective organ donor that corresponded to 29 per million inhabitants (pmi) in 2012 and 27.4 pmi in 2013. Out of 626 effective deceased organ donors, 491 (79%) were donors after brain death (DBD) and 135 (21%) donors after circulatory death (DCD), respectively. The majority (125/135; 93%) of DCD donors were DCD Maastricht category III donors and there were 7 (5%) donations following euthanasia. Family refusal tended to be lower for DCD (10.4%) compared to DBD donors (13.4%). Despite the increasing DCD donation rate, DBD donation remains stable in Belgium. The donor age is still increasing, reaching a median age of 53 years (range 0–90). Spontaneous intracranial bleeding (39.3%) and cranio-cerebral trauma (25%) remained the most frequent reasons of death. The number of living related kidney transplantations (57 in 2012 and 63 in 2013) followed the international trend albeit in Belgium it is still very limited. Nevertheless this activity could explain that the number of patients waiting for kidney transplantation (770) reached an absolute minimum in 2013. Except the reduced waiting list for lung transplantation (from 119 patients in 2011 to 85 in 2013), the waiting list remained stable for the other organs but almost 200 patients still died while on the waiting list.ConclusionsBelgium demonstrated the highest number of effective organ donors that corresponded to 29 per million inhabitants (pmi) in 2012 and 27.4 pmi in 2013. Thus far, and in contrast with other countries, there is no erosion of DBD in the DCD donor organ pool, but it is the important responsibility of all transplant centers and donor hospitals to avoid a substitution from DBD by DCD donors.     

A National Program Toward Improving Renal Health: Advancing Organ Donation Awareness

Background

Despite the national advocacy campaign for kidney transplantation from deceased donors in the Philippines 96% of kidneys transplanted into 721 kidney transplants from 1999 to 2001 came from living donors. A national survey on the knowledge, attitudes and perceptions of Filipinos on organ donation in 2001 showed factors that disadvantaged deceased organ donation to be poor understanding of “brain death,” religion, and fear of the operation. These concerns were addressed and another survey was conducted in 2005.

Objectives

To compare knowledge, attitudes, and perceptions of Filipinos on organ donation between 2001 and 2005, and compare the number of kidney transplants from deceased donors between 2001 until 2008.

Methods

Two surveys in 15 regions of the Philippines were conducted using multistage sampling. Using a structured questionnaire there were 2000 respondents in 2001, and 2140 in 2005. Analysis was performed using chi-square analysis.

Results

The majority of respondents knew about kidney donation. Between 2001 and 2005, there was increased awareness that transplants came from both living and deceased donors (37% to 41%) and a decline in those believing transplants came only from deceased donors (14% to 9%). Willingness to become a living (59% to 87%) or a deceased donor (35% to 49%) increased. The increase in transplantation from deceased donors from an average of 10 per year from 1999 to 2001 to 31 per year from 2006 to 2008.

Conclusion

Increased awareness about kidney donation among Filipinos, improved consent to become an organ donor, and an increase in kidney transplantation from deceased donors occurred from 2001 to 2008.     

Future Lawyers Support Organ Donation and Transplantation

In 2016 the total number of solid organ transplantations in Poland was 1469; the number of patients on waiting lists was approximately 1600 every month, and demand for organs is increasing every year. Transplantation has achieved increasing support and acceptance among Polish people; however, there are still many ethical, moral, and legal barriers related to this form of treatment of end-stage organ failure.

Aspects of Present and Future Data Presentation in Scandiatransplant

Scandiatransplant is the Nordic organ exchange organization having existed for almost 40 years. With close collaboration between transplant centers in the Nordic countries, it has been valuable to ensure the optimal usage of available organs. The heart is the most often exchanged organ within the collaboration. It has been decided to create a priority for hyperimmunized kidney patients for compulsory exchange of organs from deceased donors.The age of the deceased organ donors has changed from younger to older donors. The evaluation of deceased kidney transplantations and deceased liver transplantations from 1995 to 2007 is shown for 4 countries. Iceland by itself is performing living donor kidney transplantations with great intensity. Scandiatransplant will make efforts to present more data than just transplantation to yield a more complete picture of organ transplantation.     

Social media and organ donation: Ethically navigating the next frontier

As the organ shortage continues to grow, the creation of social media communities by transplant hospitals and the public is rapidly expanding to increase the number of living donors. Social media communities are arranged in myriad ways and without standardization, raising concerns about transplant candidates’ and potential donors’ autonomy and quality of care. Social media communities magnify and modify extant ethical issues in deceased and living donation related to privacy, confidentiality, professionalism, and informed consent, and increase the potential for undue influence and coercion for potential donors and transplant candidates. Currently, no national ethical guidelines have been developed in the United States regarding the use of social media to foster organ transplantation. We provide an ethical framework to guide transplant stakeholders in using social media for public and patient communication about transplantation and living donation, and offer recommendations for transplant clinical practice and future research.     

Scandiatransplant report 2009

Scandiatransplant is the Nordic organ exchange organization that has existed for 41 years by a close collaboration between transplant centers. It has been valuable to ensure the optimal usage of available organs for transplantation. Analyzing the database for the past 15 years (1995-2009) revealed that the fraction of organ donors in the age category 60 to 90 years has increased considerably. The number of retrieved organs from deceased donors increased for kidney, liver, and lungs but only slightly for hearts. In the last time period, the mean number of organs retrieved per deceased donor counting only those having a recipient increased to 3.7 for younger donors and to 2.6 from the older group. In 2009, the STAMP (Scandiatransplant acceptable mismatch program) was launched to help highly immunized kidney patients. In 2009, kidney transplantations exhibited for Norway, 60 per million people (pmp); more than 40 pmp for Sweden and for Denmark; approximately 35 pmp for Finland; and more than 20 pmp for the living donor kidney transplantations in Iceland. The best year ever within Scandiatransplant with respect to total number of organ transplantations from deceased and living donors was 2009.     

The Impact of Organ Procurement Injury on Transplant Organ Availability

Patients on the transplant waiting list continue to have a significant wait time as organ supply remains low. Many initiatives have been undertaken in the last few years to attempt to increase the organ allograft supply. As organ procurement organizations have attempted to increase their procurement of organs from deceased donors, emphasis has been placed on avoidance of injury to organs during procurement. To analyze the success of this attention, data were collected from 29 of 57 organ procurement organizations in the United States. Data collection was from November 2017 to January 2020. Total injury rate ranged from 6% (donation after brain death) to 8.4% (donation after circulatory death). Level 3 injuries, those resulting in loss of the allograft, ranged from 1.1% in donation after brain death to 1.6% in donation after circulatory death. The most likely injured organ resulting in loss of viability (level 3 injury) during procurement was the right kidney. We noted that among donors with procurement injuries, a higher number had no previous abdominal surgery and there were more injuries noted from attending surgeons (compared to trainees). Deceased donor procurement organ injuries, though rare, lead to substantial loss of transplantable organs every year. Given that the United Network for Organ Sharing has recorded >10,000 deceased donors yearly for the past few years, such injuries can result in hundreds of transplantable organs lost. In this article we detailed the incidence and degree of injury and some variables that may be associated with these injuries.     

Stimulus for Organ Donation: A Survey of the American Society of Transplant Surgeons Membership

Federal legislation has been proposed to modify the National Organ Transplant Act in a way that would permit government-regulated strategies, including financial incentives, to be implemented and evaluated. The Council and Ethics Committee of the American Society of Transplant Surgeons conducted a brief web-based survey of its members' (n = 449, 41.6% response rate) views on acceptable or unacceptable strategies to increase organ donation. The majority of the membership supports reimbursement for funeral expenses, an income tax credit on the final return of a deceased donor and an income tax credit for registering as an organ donor as strategies for increasing deceased donation. Payment for lost wages, guaranteed health insurance and an income tax credit are strategies most strongly supported by the membership to increase living donation. For both deceased and living donation, the membership is mostly opposed to cash payments to donors, their estates or to next-of-kin. There is strong support for a government-regulated trial to evaluate the potential benefits and harms of financial incentives for both deceased and living donation. Overall, there is strong support within the ASTS membership for changes to NOTA that would permit the implementation and careful evaluation of indirect, government-regulated strategies to increase organ donation.     

The Impact of Tax Policies on Living Organ Donations in the United States

In an effort to increase living organ donation, fifteen states passed tax deductions and one a tax credit to help defray potential medical, lodging and wage loss costs between 2004 and 2008. To assess the impact of these policies on living donation rates, we used a differences‐in‐differences strategy that compares the pre‐ and postlegislation change in living donations in states that passed legislation against the same change in those states that did not. We found no statistically significant effect of these tax policies on donation rates. Furthermore, we found no evidence of any lagged effects, differential impacts by gender, race or donor relationship, or impacts on deceased donation. Possible hypotheses to explain our findings are: the cash value of the tax deduction may be too low to defray costs faced by donors, lack of public awareness about the existence of these policies, and that states that were proactive enough to pass tax policy laws may have already depleted donor pools with previous interventions.
