RESUMO
The first 2 living recipients of pig hearts died unexpectedly within 2 months, despite both recipients receiving what over 30 years of nonhuman primate (NHP) research would suggest were the optimal gene edits and immunosuppression to ensure success. These results prompt us to question how faithfully data from the NHP model translate into human outcomes. Before attempting any further heart xenotransplants in living humans, it is highly advisable to gain a more comprehensive understanding of why the promising preclinical NHP data did not accurately predict outcomes in humans. It is also unlikely that additional NHP data will provide more information that would de-risk a xenoheart clinical trial because these cases were based on the best practices from the most successful NHP results to date. Although imperfect, the decedent model offers a complementary avenue to determine appropriate treatment regimens to control the human immune response to xenografts and better understand the biologic differences between humans and NHP that could lead to such starkly contrasting outcomes. Herein, we explore the potential benefits and drawbacks of the decedent model and contrast it to the advantages and disadvantages of the extensive body of data generated in the NHP xenoheart transplantation model.

Partial heart transplant (PHT) is a recent clinical innovation involving the transplantation of a segment of the heart (valves) directly from the deceased donor into the recipient patient. This procedure holds out the possibility of significant benefit, especially for pediatric patients because these grafts show growth potential after transplant, reducing or eliminating the current need for repeat procedures. The clinical process for donation and transplant of partial heart (PH) grafts generally follows an organ clinical pathway; however, the Food and Drug Administration has recently stated its intent to regulate PH as tissues, raising a host of regulatory considerations. PHT requires donor testing and eligibility determinations within a short, clinically viable timeframe and, similar to organ transplant, involves donor-recipient matching. Waitlist allocation policies that are a regulatory focus of the Organ Procurement and Transplantation Network including equity and efficiency may become relevant. Oversight of PHT by the Organ Procurement and Transplantation Network could be accomplished through interpretation of the vascular composite allograft definition or through designation by the US Department of Health and Human Services of PH grafts as organs. While some clinical questions remain unanswered, it is important to carefully address these regulatory considerations to support the emergence of this innovation and ensure the continued trust of the donating public and the patients who may benefit from PHT.
RESUMO
Organ transplantation is a life-saving treatment for end-stage organ failure patients, but the US faces a shortage of available organs. US policies incentivize identifying recipients for all recovered organs. Technological advancements have extended donor organ viability, creating new opportunities for long-distance transport and international sharing. We aimed to assess organ exports from deceased US donors to candidates abroad, a component of allocation policy allowed without suitable domestic candidates. Based on national SRTR data from January 2014-September 2023, 388,342 organs were recovered for transplantation, with 511(0.13%) exported. Most exported organs were lungs(80%). Exported lung donors were older(41 vs. 34 years,p<0.001), more likely Hepatitis-C positive(22% vs. 4%,p<0.001), and more likely donors after circulatory death(20% vs 7%,p<0.001). Lungs that were eventually exported were offered to more US PTRs (median=65) than those kept in the US(median=21 and 41 for lungs recovered by non-exporting and exporting OPOs;p<0.001). Our study highlights the necessity for further research and clear policy initiatives to balance the benefits of cross-border sharing while considering potential opportunities for more aggressive organ allocation within the US.
RESUMO
Normothermic machine perfusion (NMP) is increasingly considered for pretransplant kidney quality assessment. However, fundamental questions about differences between in vivo and ex vivo renal function, as well as the impact of ischemic injury on ex vivo physiology, remain unanswered. This study utilized magnetic resonance imaging (MRI), alongside conventional parameters to explore differences between in vivo and ex vivo renal function and the impact of warm ischemia on a kidney's behavior ex vivo. Renal MRI scans and samples were obtained from living pigs (n = 30) in vivo. Next, kidney pairs were procured and exposed to minimal, or 75 minutes of warm ischemia, followed by 6 hours of hypothermic machine perfusion. Both kidneys simultaneously underwent 6-hour ex vivo perfusion in MRI-compatible NMP circuits to obtain multiparametric MRI data. Ischemically injured ex vivo kidneys showed a significantly altered regional blood flow distribution compared to in vivo and minimally damaged organs. Both ex vivo groups showed diffusion restriction relative to in vivo. Our findings underscore the differences between in vivo and ex vivo MRI-based renal characteristics. Therefore, when assessing organ viability during NMP, it should be considered to incorporate parameters beyond the conventional functional markers that are common in vivo.
RESUMO
Some United States organ procurement organizations transfer deceased organ donors to donor care units (DCUs) for recovery procedures. We used Organ Procurement and Transplantation Network data, from April 2017 to June 2021, to describe the proximity of adult deceased donors after brain death to DCUs and understand the impact of donor service area (DSA) boundaries on transfer efficiency. Among 19 109 donors (56.1% of the cohort) in 25 DSAs with DCUs, a majority (14 593 [76.4%]) were in hospitals within a 2-hour drive. In areas with DCUs detectable in the study data set, a minority of donors (3582 of 11 532 [31.1%]) were transferred to a DCU; transfer rates varied between DSAs (median, 27.7%, range, 4.0%-96.5%). Median hospital-to-DCU driving times were not meaningfully shorter among transferred donors (50 vs 51 minutes for not transferred, P < .001). When DSA boundaries were ignored, 3241 cohort donors (9.5%) without current DCU access were managed in hospitals within 2 hours of a DCU and thus potentially eligible for transfer. In summary, approximately half of United States deceased donors after brain death are managed in hospitals in DSAs with a DCU. Transfer of donors between DSAs may increase DCU utilization and improve system efficiency.

Current policies in organ and tissue donation and transplantation (OTDT) systems in Canada and the United States unnecessarily restrict access to donation for sexual and gender minorities (SGMs) and pose safety risks to transplant recipients. We compare SGM-relevant policies between the Canadian and United States systems. Policy domains include the risk assessment of living and deceased organ and tissue donors, physical examination considerations, viral testing recommendations, and informed consent and communication. Identified gaps between current evidence and existing OTDT policies along with differences in SGM-relevant policies between systems, represent an opportunity for improvement. Specific recommendations for OTDT system policy revisions to achieve these goals include the development of behavior-based, gender-neutral risk assessment criteria, a reduction in current SGM no-sexual contact period requirements pending development of inclusive criteria, and destigmatization of sexual contact with people living with human immunodeficiency virus. OTDT systems should avoid rectal examinations to screen for evidence of receptive anal sex without consent and mandate routine nucleic acid amplification test screening for all donors. Transplant recipients must receive enhanced risk-to-benefit discussions regarding decisions to accept or decline an offer of an organ classified as increased risk. These recommendations will expand the donor pool, enhance equity for SGM people, and improve safety and outcomes for transplant recipients.

BACKGROUND & AIMS: The National Liver Offering Scheme (NLOS) was introduced in the UK in 2018 to offer livers from deceased donors to patients on the national waiting list based, for most patients, on calculated transplant benefit. Before NLOS, livers were offered to transplant centres by geographic donor zones and, within centres, by estimated recipient need for a transplant. METHODS: UK Transplant Registry data on patient registrations and transplants were analysed to build statistical models for survival on the list (M1) and survival post-transplantation (M2). A separate cohort of registrations - not seen by the models before - was analysed to simulate what liver allocation would have been under M1, M2 and a transplant benefit score (TBS) model (combining both M1 and M2), and to compare these allocations to what had been recorded in the UK Transplant Registry. The number of deaths on the waiting list and patient life years were used to compare the different simulation scenarios and to select the optimal allocation model. Registry data were monitored, pre- and post-NLOS, to understand the performance of the scheme. RESULTS: The TBS was identified as the optimal model to offer donation after brain death (DBD) livers to adult and large paediatric elective recipients. In the first 2 years of NLOS, 68% of DBD livers were offered using the TBS to this type of recipient. Monitoring data indicate that mortality on the waiting list post-NLOS significantly decreased compared with pre-NLOS (p <0.0001), and that patient survival post-listing was significantly greater post- compared to pre-NLOS (p = 0.005). CONCLUSIONS: In the first two years of NLOS offering, waiting list mortality fell while post-transplant survival was not negatively impacted, delivering on the scheme's objectives. IMPACT AND IMPLICATIONS: The National Liver Offering Scheme (NLOS) was introduced in the UK in 2018 to increase transparency of the deceased donor liver offering process, maximise the overall survival of the waiting list population, and improve equity of access to liver transplantation. To our knowledge, it is the first scheme that offers organs based on statistical prediction of transplant benefit: the transplant benefit score. The results are important to the transplant community - from healthcare practitioners to patients - and demonstrate that, in the first two years of NLOS offering, waiting list mortality fell while post-transplant survival was not negatively impacted, thus delivering on the scheme's objectives. The scheme continues to be monitored to ensure that the transplant benefit score remains up-to-date and that signals that suggest the possible disadvantage of some patients are investigated.

RATIONALE & OBJECTIVE: South Asian (SA) Canadians with kidney failure have a 50%-77% lower likelihood of kidney transplant and are less likely to identify potential living donors (LDs). This study aimed to identify health system-, patient-, and community-level barriers and facilitators for accessing LD kidney transplantation in the SA community to inform the development of health system- and community-level interventions to address barriers. STUDY DESIGN: Qualitative study. SETTING & PARTICIPANTS: 20 SA recipients of an LD or deceased-donor kidney transplant, 10 SA LDs, and 41 general SA community members. ANALYTICAL APPROACH: In-depth multilingual interviews were conducted with recipients and LDs. Gender-, language-, and age-stratified focus groups were conducted with general SA community members. Summative content analysis was used to analyze the data. RESULTS: Hesitancy in approaching potential donors, fear about the health of potential LDs, information gaps, language barriers, and challenges evaluating out-of-country donors were highlighted as significant barriers by recipients, and financial concerns and information gaps were identified by donors. Cultural barriers in the SA community were highlighted by donors, recipients, and community members as critical factors when considering donation and transplant; women and elderly SA Canadians highlighted nuanced challenges. Participants reported generally a favorable perception of their health care teams, citing SA representation in the teams as important to providing culturally and linguistically sensitive care. LIMITATIONS: Limited geographic, race, and cultural representation and reliance on virtual data collection. CONCLUSIONS: This study highlights several culturally relevant barriers to donation and transplant that are potentially modifiable through patient-, health system-, and community-focused engagement and education.

As the number of designated organ donors continues to lag behind the number of waiting list patients, teenagers remain a promising demographic of potential organ donors. The current study enlisted Michigan and Ohio driver education students to participate in an online digital learning intervention, License to Save Lives (LTSL). Students were randomly assigned to either an interactive or noninteractive LTSL intervention. Across both states, the pretest-posttest design revealed greater knowledge among students following exposure to either the interactive or noninteractive LTSL program. No attitudinal or behavioral differences emerged between the interactive and noninteractive conditions. Michigan (39.82%) and Ohio (58.10%) students registered to be organ donors at a respectable rate. The results are discussed with an emphasis on feasibility and sustainability as well as the promise for digital games to promote organ donation knowledge, attitude, and registration among teenagers.

INTRODUCTION: The decision to become a living donor requires consideration of a complex, interactive array of factors that could be targeted for clinical, policy, and educational interventions. Our objective was to assess how financial barriers interact with motivators, other barriers, and facilitators during this process. METHODS: Data were obtained from a public survey assessing motivators, barriers, and facilitators of living donation. We used multivariable logistic regression and consensus k-means clustering to assess interactions between financial concerns and other considerations in the decision-making process. RESULTS: Among 1592 respondents, the average age was 43; 74% were female and 14% and 6% identified as Hispanic and Black, respectively. Among employed respondents (72%), 40% indicated that they would not be able to donate without lost wage reimbursement. Stronger agreement with worries about expenses and dependent care challenges was associated with not being able to donate without lost wage reimbursement (OR = 1.2, 95% CI = 1.0-1.3; OR = 1.2, 95% CI = 1.1-1.3, respectively). Four respondent clusters were identified. Cluster 1 had strong motivators and facilitators with minimal barriers. Cluster 2 had barriers related to health concerns, nervousness, and dependent care. Clusters 3 and 4 had financial barriers. Cluster 3 also had anxiety related to surgery and dependent care. CONCLUSIONS: Financial barriers interact primarily with health and dependent care concerns when considering living organ donation. Targeted interventions to reduce financial barriers and improve provider communication regarding donation-related risks are needed.

BACKGROUND: The 2018 UNOS allocation policy change deprioritized geographic boundaries to organ distribution, and the effects of this change have been widespread. The aim of this investigation was to analyze changes in donor transplant center distance for organ travel and corresponding outcomes before and after the allocation policy change. METHODS: The UNOS database was utilized to identify all adult patients waitlisted for heart transplants from 2016 to 2021. Transplant centers were grouped by average donor heart travel distance based on whether they received more or less than 50% of organs from >250 miles away. Descriptive statistics were provided for waitlisted and transplanted patients. Regression analyses modeled waitlist mortality, incidence of transplant, overall survival, and graft survival. RESULTS: Centers with a longer average travel distance had a higher mean annual transplant volume with a reduction in total days on a waitlist (86.6 vs. 149.2 days), an increased cold ischemic time (3.6 vs. 3.2 h), with no significant difference in post-transplant overall survival or graft survival. CONCLUSIONS: The benefits of reducing waitlist time while preserving post-transplant outcomes extend broadly. The trends observed in this investigation will be useful as we revise organ transplant policy in the era of new organ procurement and preservation techniques.

England switched to an opt-out system of consent in 2020 aiming to increase the number of organs available. Spain also operates an opt-out system yet has almost twice the organ donations per million population compared with England. We aimed to identify both differences and similarities in the consent policies, documents and procedures in deceased donation between the two countries using comparative qualitative content and discourse analysis. Spain had simpler, locally tailored documents, the time taken for families to review and process information may be shorter, there were more pathways leading to organ donation in Spain, and more robust legal protections for the decisions individuals made in life. The language in the Spanish documents was one of support and reassurance. Documents in England by comparison appeared confusing, since additions were designed to protect the NHS against risk and made to previous document versions to reflect the law change rather than being entirely recast. If England's ambition is to achieve consent rates similar to Spain this analysis has highlighted opportunities that could strengthen the English system-by giving individuals' decisions recorded on the organ donor register legal weight, alongside unifying and simplifying consent policies and procedures to support families and healthcare professionals.

The shortage of organs for transplantations is increasing in Europe as well as globally. Many initiatives to the organ shortage, such as opt-out systems for deceased donation and expanding living donation, have been insufficient to meet the rising demand for organs. In recurrent discussions on how to reduce organ shortage, financial incentives and removal of disincentives, have been proposed to stimulate living organ donation and increase the pool of available donor organs. It is important to understand not only the ethical acceptability of (dis)incentives for organ donation, but also its societal acceptance. In this review, we propose a research agenda to help guide future empirical studies on public preferences in Europe towards the removal of disincentives and introduction of incentives for organ donation. We first present a systematic literature review on public opinions concerning (financial) (dis)incentives for organ donation in European countries. Next, we describe the results of a randomized survey experiment conducted in the United States. This experiment is crucial because it suggests that societal support for incentivizing organ donation depends on the specific features and institutional design of the proposed incentive scheme. We conclude by proposing this experiment's framework as a blueprint for European research on this topic.

Intensive Care to facilitate Organ Donation (ICOD) consists of the initiation or continuation of intensive care measures in patients with a devastating brain injury (DBI) in whom curative treatment is deemed futile and death by neurological criteria (DNC) is foreseen, to incorporate organ donation into their end-of-life plans. In this study we evaluate the outcomes of patients subject to ICOD and identify radiological and clinical factors associated with progression to DNC. In this first prospective multicenter study we tested by multivariate regression the association of clinical and radiological severity features with progression to DNC. Of the 194 patients, 144 (74.2%) patients fulfilled DNC after a median of 25 h (95% IQR: 17-44) from ICOD onset. Two patients (1%) shifted from ICOD to curative treatment, both were alive at discharge. Factors associated with progression to DNC included: age below 70 years, clinical score consistent with severe brain injury, instability, intracranial hemorrhage, midline shift ≥5 mm and certain types of brain herniation. Overall 151 (77.8%) patients progressed to organ donation. Based on these results, we conclude that ICOD is a beneficial and efficient practice that can contribute to the pool of deceased donors.

In this study, 10 years of procurement quality monitoring data were analyzed to identify potential risk factors associated with procurement-related injury and their association with long-term graft survival. All deceased kidney, liver, and pancreas donors from 2012 to 2022 and their corresponding recipients in the Netherlands were retrospectively included. The incidence of procurement-related injuries and potential risk factors were analyzed. Of all abdominal organs procured, 23% exhibited procurement-related injuries, with a discard rate of 4.0%. In kidneys and livers, 23% of the grafts had procurement-related injury, with 2.5% and 4% of organs with procurement-related injury being discarded, respectively. In pancreas procurement, this was 27%, with a discard rate of 24%. Male donor gender and donor BMI >25 were significant risk factors for procurement-related injury in all three abdominal organs, whereas aberrant vascularization was significant only for the kidney and liver. In the multivariable Cox regression analyses, procurement-related injury was not a significant predictor for graft failure (kidney; HR 0.99, 95% CI 0.75-1.33, p = 0.99, liver; HR 0.92, 95% CI 0.66-1.28, p = 0.61, pancreas: HR 1.16; 95% CI 0.16-8.68, p = 0.88). The findings of this study suggest that transplant surgeons exhibited good decision-making skills in determining the acceptability and repairability of procurement-related injuries.

We aimed to assess the impact of hospital characteristics on the outcomes of detected possible brain-dead donors, in our organ procurement network in Iran. Data was collected through twice-daily calls with 57 hospitals' intensive care units and emergency departments over 1 year. The donation team got involved when there was suspicion of brain death before the hospital officially declared it. The data was categorized by hospital size, presence of neurosurgery/trauma departments, ownership, and referral site. Out of 813 possible donors, 315 were declared brain dead, and 203 were eligible for donation. After conducting family interviews (consent rate: 62.2%), 102 eligible donors became actual donors (conversion rate: 50.2%). While hospital ownership and the presence of trauma/neurosurgery care did not affect donation, early referral from the emergency department had a positive effect. Therefore, we strongly recommend prioritizing possible donor identification in emergency rooms and involving the organ donation team as early as possible. The use of twice-daily calls for donor identification likely contributed to the consistency in donation rates across hospitals, as this approach involves the donation team earlier and mitigates the impact of hospital characteristics. Early detection of possible donors from the emergency department is crucial in improving donation rates.

BACKGROUND: HIV+-to-HIV+ organ transplantation has demonstrated promise and is now authorized for research purposes in certain countries. However, organ transplantation is dependent on the availability of organ donors. We assessed the awareness and willingness to donate organs among people with HIV (PWH) in Uganda. METHODS: We conducted a multicenter cross-sectional study between October 2023 and January 2024 in four large HIV clinics in Northern Uganda. The study population consisted of PWH. A structured questionnaire was used to collect data regarding awareness, willingness, and beliefs regarding organ donation. Organ donation was defined as the willingness to be a living donor of a solid organ. We conducted multivariable logistic regression to assess for an association between willingness to donate organs and selected exposures. Data were analyzed in Stata version 15.0. Results are expressed as adjusted odds ratio (AOR) with 95% confidence intervals (CI). RESULTS: A total of 232 participants were recruited. The mean age ± standard deviation of the participants was 42.2±11.8 years. All participants were on antiretroviral therapy. Sixty-two (26.7%) had a CD4 count less than or equal to 200 cells/mm3. The majority (80.6%, n = 187) had ever heard of organ donation. Slightly more than a third (34.9%, n = 81) were willing to donate organs. Factors associated with willingness to be a living organ donor included being female (AOR: 1.56; 95% CI: 1.15-2.11), having a tertiary education level (AOR: 1.79; 95% CI: 1.03-3.11), average monthly income >500 000 UGX (135.1USD) (AOR: 5.5; 95% CI: 1.97-15.40), ever heard about organ donation (AOR: 5.4; 95% CI: 1.67-17.8), and attending an organ donation campaign (AOR: 2.0; 95% CI: 1.07-3.74). CONCLUSIONS: Awareness about organ donation was high but the willingness to be a living organ donor was low among PWH in Uganda. There is a need to sensitize the community about the need and benefits of organ donation with the involvement of media and the healthcare workers.

Although pediatric organ donation represents a small proportion of overall organ donation, children and adolescents make a significant contribution to the pool of donated organs. In this study 252 solid organs were collected from children and adolescent. Two hundred and two recipients benefited from 62 pediatric organ donors, with a recipient/donor ratio of 3.3.
BACKGROUND: Pediatric organ donors represent a small but important portion of the deceased donor pool, helping both children and adults in the transplant waitlist. Despite this, pediatric donation remains an overlooked subject of research. METHODS: Retrospective, singlecenter, descriptive study. All brain death patients under 18 years old who were admitted to the Intensive Care Unit (ICU) between January 1st, 2006, and December 31st, 2021, and who were eligible for organ donation were included. RESULTS: Between January 2006 and December 2021, 200 children/adolescent died in the ICU. From those, 62 patients (31%) were considered eligible for organ donation. The mean age of the donors at the time of death was 8.8 years. Sixtythree per cent were male. The most frequent cause of death was traumatic brain injury (n = 36). Two hundred and fifty organs were collected benefitting 202 persons with a recipient/donor ratio of 3.3. Kidneys were the most frequent organ donated (n = 116), followed by liver (n = 56) and heart (n = 34). The median number of organs donated per child was four, with a minimum of 1 organ and maximum of 8. CONCLUSIONS: Pediatric organ donation represents a small proportion of overall organ donation, but children and adolescents have important impact on the lives they save. The field of pediatric organ donation needs more research to better understand the contribution of the pediatric population to both adults and children who wait for an organ.

BACKGROUND: Italy presently does not have a pediatric organ donation program after cardiocirculatory determination of death (pDCDD). Before implementing a pDCDD program, many centers globally have conducted studies on the attitudes of pediatric intensive care unit (PICU) staff. This research aims to minimize potential adverse reactions and evaluate the acceptance of the novel donation practice. METHODS: We conducted an electronic and anonymous survey on attitudes toward pDCDD among healthcare professionals (HCPs) working at eight Italian PICUs. The survey had three parts: (I) questions about general demographic data; (II) 18 statements about personal wishes to donate, experience of discussing donation, and knowledge about donation; (III) attitudinal statements regarding two pediatric Maastricht III scenarios of organ donation. RESULTS: The response rate was 54.4%, and the majority of respondents were nurses. Of those who responded, 45.3% worked in the Center, 40.8% in the North, and 12.8% in the South of Italy. In total, 93.9% supported pediatric organ and tissue donation, 90.3% supported donation after neurological determination of death (DNDD), 78.2% supported pDCDD, and 69.7% felt comfortable about the idea of participating in pDCDD on Type III patients, with a higher percentage of supportive responses in the Center (77.2%) than in the North (65.1%) and South (54.5%) of Italy (p-value < 0.004). Concerning scenarios, 79.3% of participants believed that organ retrieval took place in a patient who was already deceased. Overall, 27.3% considered their knowledge about DCDD to be adequate. CONCLUSIONS: Our study provides insight into the attitudes and knowledge of PICU staff members regarding pDCDD in Italy. Despite a general lack of knowledge on the subject, respondents showed positive attitudes toward pDCDD and a strong consensus that the Italian legislation protocol for determining death based on cardiocirculatory criteria respects the "dead donor rule." There were several distinctions among the northern, central, and southern regions of Italy, and in our view, these disparities can be attributed to the varying practices of commemorating the deceased. In order to assess how practice and training influence the attitude of PICU staff members, it would be interesting to repeat the survey after the implementation of a program.

BACKGROUND: Western Norway has the lowest number of actual deceased organ donors per million inhabitants in Norway. We wished to find the total number of potential donors and donor organs during 2 years at Haukeland University Hospital, the largest hospital in the region, and evaluate where and why potential donors were lost. METHODS: We evaluated all patients who died at Haukeland University Hospital in 2018-19. We checked if intensive care patients, filling the criteria as organ donors after brain death, became donors, and the reasons why potential donors were lost. We also estimated the number of potential donors after circulatory death. We checked if patients transferred from the intensive care units and patients never admitted to intensive care were potential donors. Location, gender, age, and possible number of organs were registered. RESULTS: Of 1453 in-hospital deaths, 20 brain-dead patients became actual donors. One brain-dead and two other potential donors, one of them discharged to a bed ward, were not evaluated at the intensive care units. Relatives refused in five patients. Three fulfilled the Norwegian criteria from 2021 as organ donors after circulatory death. Ten potential donors after brain death were never admitted to intensive care and died on neurological or neurosurgical wards. If all potential organ donors were realised, the number of donors would double. The number of transplanted organs would increase less, as organs used per donor would drop from 3.50 to 2.90. CONCLUSION: Our study cannot explain the low number of donors in our region compared with the rest of Norway. If all potential donations were implemented, the number of actual donors would double. Patients dying outside the intensive care units represent the largest potential source for extra donors, maximally increasing the number of donors by 42%, high-quality livers 44% and kidneys 18%. Introducing organ donation after circulatory death may increase the number of donors by 15% and the number of high-quality livers and kidneys by 12%.
