RESUMEN

Organ donation should neither enrich donors nor impose financial burdens on them. We described the scope of health care required for all living kidney donors, reflecting contemporary understanding of long-term donor health outcomes; proposed an approach to identify donor health conditions that should be covered within the framework of financial neutrality; and proposed strategies to pay for this care. Despite the Affordable Care Act in the United States, donors continue to have inadequate coverage for important health conditions that are donation related or that may compromise postdonation kidney function. Amendment of Medicare regulations is needed to clarify that surveillance and treatment of conditions that may compromise postdonation kidney function following donor nephrectomy will be covered without expense to the donor. In other countries lacking health insurance for all residents, sufficient data exist to allow the creation of a compensation fund or donor insurance policies to ensure appropriate care. Providing coverage for donation-related sequelae as well as care to preserve postdonation kidney function ensures protection against the financial burdens of health care encountered by donors throughout their lives. Providing coverage for this care should thus be cost-effective, even without considering the health care cost savings that occur for living donor transplant recipients.

RESUMEN

Kidney transplant recipients require specialized medical care and may be at risk for adverse health outcomes when their care is transferred. This document provides opinion-based recommendations to facilitate safe and efficient transfers of care for kidney transplant recipients including minimizing the risk of rejection, avoidance of medication errors, ensuring patient access to immunosuppressant medications, avoidance of lapses in health insurance coverage, and communication of risks of donor disease transmission. The document summarizes information to be included in a medical transfer document and includes suggestions to help the patient establish an optimal therapeutic relationship with their new transplant care team. The document is intended as a starting point towards standardization of transfers of care involving kidney transplant recipients.

RESUMEN

The supply of organs­particularly kidneys­donated by living and deceased donors falls short of the number of patients added annually to transplant waiting lists in the United States. To remedy this problem, a number of prominent physicians, ethicists, economists and others have mounted a campaign to suspend the prohibitions in the National Organ Transplant Act of 1984 (NOTA) on the buying and selling of organs. The argument that providing financial benefits would incentivize enough people to part with a kidney (or a portion of a liver) to clear the waiting lists is flawed. This commentary marshals arguments against the claim that the shortage of donor organs would best be overcome by providing financial incentives for donation. We can increase the number of organs available for transplantation by removing all financial disincentives that deter unpaid living or deceased kidney donation. These disincentives include a range of burdens, such as the costs of travel and lodging for medical evaluation and surgery, lost wages, and the expense of dependent care during the period of organ removal and recuperation. Organ donation should remain an act that is financially neutral for donors, neither imposing financial burdens nor enriching them monetarily.

RESUMEN

Public perception and misperceptions of socioeconomic disparities affect the willingness to donate organs. To improve our understanding of the flow of deceased donor kidneys, we analyzed socioeconomic status (SES) and racial/ethnic gradients between donors and recipients. In a retrospective cohort study, traditional demographic and socioeconomic factors, as well as an SES index, were compared in 56,697 deceased kidney donor and recipient pairs transplanted between 2007 and 2012. Kidneys were more likely to be transplanted in recipients of the same racial/ethnic group as the donor (p < 0.001). Kidneys tended to go to recipients of lower SES index (50.5% of the time, p < 0.001), a relationship that remained after adjusting for other available markers of donor organ quality and SES (p < 0.001). Deceased donor kidneys do not appear to be transplanted from donors of lower SES to recipients of higher SES; this information may be useful in counseling potential donors and their families regarding the distribution of their organ gifts.

RESUMEN

A policy proposal relating to transplantation of deceased donor organs into nonresidents of the United States was jointly sponsored by the Organ Procurement and Transplantation Network (OPTN)/United Network for Organ Sharing (UNOS) International Relations and Ethics Committees and approved by the OPTN/UNOS Board in June 2012. The proposal followed prior acceptance by the Board of the definitions of "travel for transplantation" and "transplant tourism" and the introduction in March 2012 of revised data collection categories for transplant candidates who are neither citizens nor residents. The most important aspect of the new policy concerns replacement of the previous so-called "5% rule" with the review of all residency and citizenship data and the preparation of a public annual report. The new policy does not prohibit organ transplantation in nonresidents. However, the policy and public data report will ensure transparency and support transplant center responsibility to account for their practices. Since the adoption of the policy, the first 19 months of data show that less than 1% of new deceased donor waitlist additions and less than 1% of transplantation recipients were non-US citizen/nonresidents candidates who traveled to the United States for purposes of transplantation. By adopting this policy, the US transplant community promotes public trust and serves as an example to the international transplant community.

RESUMEN

While kidney paired donation (KPD) enables the utilization of living donor kidneys from healthy and willing donors incompatible with their intended recipients, the strategy poses complex challenges that have limited its adoption in United States and Canada. A consensus conference was convened March 29-30, 2012 to address the dynamic challenges and complexities of KPD that inhibit optimal implementation. Stakeholders considered donor evaluation and care, histocompatibility testing, allocation algorithms, financing, geographic challenges and implementation strategies with the goal to safely maximize KPD at every transplant center. Best practices, knowledge gaps and research goals were identified and summarized in this document.

RESUMEN

The Transplantation Society, in collaboration with the Canadian Society of Transplantation, organized a forum on education on ODT for schools. The forum included participants from around the world, school boards, and representatives from different religions. Participants presented on their countries' experience in the area of education on ODT. Working groups discussed about technologies for education, principles for sharing of resources globally, and relationships between education, and health authorities and non-governmental organizations. The forum concluded with a discussion about how to best help existing programs and those wishing to start educational programs on ODT.

RESUMEN

Organ procurement organizations (OPOs) report a nearly fourfold difference in donor availability as measured by eligible deaths per million population (PMP) based on hospital referrals. We analyzed whether mortality data help explain geographic variation in organ supply as measured by the number of eligible deaths for organ donation. Using the 2007 National Center for Health Statistics' mortality data, we analyzed deaths occurring in acute care hospitals, aged ≤ 70 years from cerebrovascular accidents and trauma. These deaths were mapped at the county level and compared to eligible deaths reported by OPOs. In 2007, there were 2 428 343 deaths reported in the United States with 42 339 in-hospital deaths ≤ 70 years from cerebrovascular accidents (CVA) or trauma that were correlated with eligible deaths PMP (r(2) = 0.79.) Analysis revealed a broad range in the death rate across OPOs: trauma deaths: 44-118 PMP; deaths from CVA: 34-118 PMP; and combined CVA and trauma: 91-229 PMP. Mortality data demonstrate that deaths by neurologic criteria of people who are likely to be suitable deceased donors are not evenly distributed across the nation. These deaths are correlated with eligible deaths for organ donation. Regional availability of organs is affected by deaths which should be accounted for in the organ allocation system.

RESUMEN

Mycobacterium tuberculosis is a ubiquitous organism that infects one-third of the world's population. In previous decades, access to organ transplantation was restricted to academic medical centers in more developed, low tuberculosis (TB) incidence countries. Globalization, changing immigration patterns, and the expansion of sophisticated medical procedures to medium and high TB incidence countries have made tuberculosis an increasingly important posttransplant infectious disease. Tuberculosis is now one of the most common bacterial causes of solid-organ transplant donor-derived infection reported in transplant recipients in the United States. Recognition of latent or undiagnosed active TB in the potential organ donor is critical to prevent emergence of disease in the recipient posttransplant. Donor-derived tuberculosis after transplantation is associated with significant morbidity and mortality, which can best be prevented through careful screening and targeted treatment. To address this growing challenge and provide recommendations, an expert international working group was assembled including specialists in transplant infectious diseases, transplant surgery, organ procurement and TB epidemiology, diagnostics and management. This working group reviewed the currently available data to formulate consensus recommendations for screening and management of TB in organ donors.

RESUMEN

Organ donation and transplant rates vary widely across the globe, but there remains an almost universal shortage of deceased donors. The unmet need for transplants has resulted in many systematic approaches to increase donor rates, but there have also been practices that have crossed the boundaries of legal and ethical acceptability. Recent years have seen intense interest from international political organizations, led by the World Health Organization, and professional bodies, led by The Transplantation Society. Their efforts have focused on the development of a series of legal and ethical frameworks, designed to encourage all countries to eradicate unacceptable practices while introducing programmes that strive to achieve national or regional self-sufficiency in meeting the need for organ transplants. These programmes should seek to reduce both the need for transplantation and also develop deceased donation to its maximum potential. Living donation remains the mainstay of transplantation in many parts of the world, and many of the controversial--and unacceptable--areas of practice are found in the exploitation of living donors. However, until lessons are learnt, and applied, from countries with highly developed deceased donor programmes, these abuses of human rights will be difficult to eradicate. A clear international framework is now in place to achieve this.

RESUMEN

The Joint Commission requires all hospitals have a policy regarding donation after cardiac death. To this date however, a quantitative analysis of adult hospital donation after cardiac death (DCD) policies and its impact on transplantation outcomes has not been reported. Specific characteristics for DCD polices were identified from 90 of the 164 (54.9%) hospitals within the New England Organ Bank's donor service area. Forty-five policies (50.0%) allow family members to be present during withdrawal of life-sustaining therapy (WLST) whereas eight (8.9%) prohibit this. Seventeen policies (18.9%) require WLST to occur in the operating room (OR); 20 (22.2%) specify a location outside of the OR. Fifty-six (62.2%) policies fail to state the method of determining death; however, some require arterial line (15 policies, 16.6%) and/or EKG (10 policies, 11.1%). These variables were not associated with organ recovery, utilization or donor ischemia time. Our regional analysis highlights the high degree of variability of hospital DCD policies, which may contribute to misunderstanding and confusion among providers and patients that may influence acceptance of this mode of donation.

RESUMEN

Donation after cardiac death (DCD) has proven effective at increasing the availability of organs for transplantation.We performed a retrospective examination of Massachusetts General Hospital (MGH) records of all 201 donors from 1/1/98 to the 11/2008, including 54 DCD, 115 DBD and 32 DCD candidates that did not progress to donation (DCD-dnp). Comparing three time periods, era 1 (01/98-12/02), era 2 (01/03-12/05) and era 3 (01/06-11/08), DCD's comprised 14.8,48.4% and 60% of donors, respectively (p = 0.002). A significant increase in the incidence of cardiovascular/cerebrovascular as cause of death was evident in era 3 versus eras 1 and 2; 74% versus 57.1% (p<0.001),as was a corresponding decrease in the incidence of traumatic death. Interestingly, we noted an increase in utilization of aggressive neurological management over time, especially in the DCD group.We detected significant changes in the make-up of the donor pool over the past decade. That the changes in diagnosis over time did not differ between DCD and DBD groups suggests this difference is not responsible for the increase in DCD rates. Instead, we suggest that changes in clinical practice, especially in management of patients with severe brain injury may account for the increased proportion of DCD.

RESUMEN

Nucleic acid testing (NAT) for HIV, HBV and HCV shortens the time between infection and detection by available testing. A group of experts was selected to develop recommendations for the use of NAT in the HIV/HBV/HCV screening of potential organ donors. The rapid turnaround times needed for donor testing and the risk of death while awaiting transplantation make organ donor screening different from screening blood-or tissue donors. In donors with no identified risk factors, there is insufficient evidence to recommend routine NAT, as the benefits of NAT may not outweigh the disadvantages of NAT especially when false-positive results can lead to loss of donor organs. For donors with identified behavioral risk factors, NAT should be considered to reduce the risk of transmission and increase organ utilization. Informed consent balancing the risks of donor-derived infection against the risk of remaining on the waiting list should be obtained at the time of candidate listing and again at the time of organ offer. In conclusion, there is insufficient evidence to recommend universal prospective screening of organ donors for HIV, HCV and HBV using current NAT platforms. Further study of viral screening modalities may reduce disease transmission risk without excessive donor loss.

RESUMEN

The extent of organ sales from commercial living donors (CLDs) or vendors has now become evident. At the Second Global Consultation on Human Transplantation of the World Health Organization's (WHO) in March 2007, it was estimated that organ trafficking accounts for 5-10% of the kidney transplants performed annually throughout the world. Patients with sufficient resources in need of organs may travel from one country to another to purchase a kidney (or liver) mainly from a poor person. Transplant centers in 'destination' countries have been well known to encourage the sale of organs to 'tourist' recipients from the 'client' countries.

RESUMEN

We examined factors associated with expanded criteria donor (ECD) kidney discard. Scientific Registry of Transplant Recipients (SRTR)/Organ Procurement and Transplantation Network (OPTN) data were examined for donor factors using logistic regression to determine the adjusted odds ratio (AOR) of discard of kidneys recovered between October 1999 and June 2005. Logistic and Cox regression models were used to determine associations with delayed graft function (DGF) and graft failure. Of the 12,536 recovered ECD kidneys, 5139 (41%) were discarded. Both the performance of a biopsy (AOR = 1.21, p = 0.02) and the degree of glomerulosclerosis (GS) on biopsy were significantly associated with increased odds of discard. GS was not consistently associated with DGF or graft failure. The discard rate of pumped ECD kidneys was 29.7% versus 43.6% for unpumped (AOR = 0.52, p < 0.0001). Among pumped kidneys, those with resistances of 0.26-0.38 and >0.38 mmHg/mL/min were discarded more than those with resistances of 0.18-0.25 mmHg/mL/min (AOR = 2.5 and 7.9, respectively). Among ECD kidneys, pumped kidneys were less likely to have DGF (AOR = 0.59, p < 0.0001) but not graft failure (RR = 0.9, p = 0.27). Biopsy findings and machine perfusion are important correlates of ECD kidney discard; corresponding associations with graft failure require further study.

RESUMEN

Graft survival rates from deceased donors aged 35 years or less among all primary pediatric kidney transplant recipients in the United States between 1996 and 2004 were retrospectively examined to determine the effect of HLA-DR mismatches on graft survival. Zero HLA-DR-mismatched kidneys had statistically comparable 5-year graft survival (71%), to 1-DR-mismatched kidneys (69%) and 2-DR-mismatched kidneys (71%). When compared to donors less than 35 years of age, the relative rate of allograft failure was 1.32 (p = 0.0326) for donor age greater than or equal to age 35. There was no statistical increase in the odds of developing a panel-reactive antibody (PRA) greater than 30% at the time of second waitlisting, based upon the degree of HLA-A, -B or -DR mismatch of the first transplant, nor was there a 'dose effect' when more HLA antigens were mismatched between the donor and recipient. Therefore, pediatric transplant programs should utilize the recently implemented Organ Procurement and Transplantation Network's (OPTN)allocation policy, which prioritizes pediatric recipients to receive kidneys from deceased donors less than 35 years of age, and should not turn down such kidney offers to wait for a better HLA-DR-matched kidney.

RESUMEN

INTRODUCTION: Prolonged lymphatic drainage and lymphocele are undesirable complications following kidney transplantation. We evaluated the impact of kidney recovery methods (deceased donor vs laparoscopic nephrectomy) on the lymphatic complications of the kidney transplant recipients. METHOD: The incidence of lymphatic complications was retrospectively analyzed in recipients of deceased donor kidneys (DD, n = 62) versus laparoscopically procured kidneys from living donors (LP, n = 61). A drain was placed in the retroperitoneal space in all recipients. The drain was maintained until the output became less than 30 mL/d with no evidence of fluid collection by ultrasound examination. RESULTS: There was no statistically significant difference in the patient demographics (age, gender, and original disease and procedure time) between two groups. The incidence of lymphocele that required therapeutic intervention was comparable in both groups (3.2%). However, the duration of drain placement was significantly longer in the LP group than in the DD group, 8.6 +/- 2.5 days versus 5.4 +/- 2.5 day, respectively (P < .05). CONCLUSION: The recipients of laparoscopically removed kidneys had a higher incidence of prolonged lymphatic leakage. More meticulous back table preparation may be required in LP kidneys to prevent prolonged lymphatic drainage after kidney transplantation. These observations may indicate that the major source of persistent lymphatic leakage is lymphatics of the allograft rather than severed recipient lymphatics.
