RESUMO

Organ, tissue, and eye donations provide opportunities to leave a legacy by saving and/or enhancing the quality of life of others. There has been little published related to tissue or eye donation in hospice/palliative care and few initiatives to facilitate donation among hospice patients/families. Donation myths, gaps in knowledge, and, most significantly, lack of donation referral processes result in missed opportunities for patient/families to consider donation. One donor has the potential to impact 75 lives or more through tissue donation and 2 lives through eye donation. Hospice/palliative care providers can play key roles related to education, advocacy, and collaboration. The support of hospice/palliative care organizations and the local Organ Procurement Organization/Tissue and Eye Recovery Agency are essential for facilitating donation opportunities. This article summarizes current literature, examines legislation and regulations related to donation, presents a case that illustrates an opportunity for hospice community based donation, and shares practices that support donation in hospice/palliative care organizations together with the local Organ Procurement Organization/Tissue and Eye Recovery Agency. This article will hopefully provide the impetus for further study and the development of practices to optimize donation in hospice/palliative care, thus providing more patients and families the opportunity to turn loss into legacy.

RESUMO

BACKGROUND: Living donor liver transplantation (LDLT) continues to be the primary modality of liver transplantation in Asia, but it accounts for about 5% of all liver transplantations in the US. ABO incompatibility is the primary reason motivated donors are declined. Although kidney paired exchanges are common, liver paired exchange (LPE) is still evolving in the US. STUDY DESIGN: This is a retrospective review (between January 1, 2019, and July 31, 2021) of our initial experience with LPE. RESULTS: A total of 10 LPEs (20 LDLTs) were performed during the study period. Seven LPEs were initiated by a nondirected O donor. The other 3 pair sets involved 1 ABO compatible and 1 ABO incompatible pair. Transplantations in a pair set were completed within a mean of 4.8 (range 1-14) days of each other. All 20 donors are doing well with no major complications at 12.7 (range 1-20) months. Seventeen of 20 recipients are alive and have good allograft function. One recipient died in the early postoperative period. Two late deaths of patients with functioning allografts were due to COVID-19 (at 8 months) and peritoneal carcinomatosis and gram-negative sepsis (at 9 months). CONCLUSIONS: LPE is feasible in a high-volume LDLT center and is a useful option to increase LDLT by overcoming ABO incompatibility. Nondirected donors can be utilized to initiate an LPE.

RESUMO

BACKGROUND AND AIMS: The European Liver Transplant Registry (ELTR) has collected data on liver transplant procedures performed in Europe since 1968. APPROACH AND RESULTS: Over a 50-year period (1968-2017), clinical and laboratory data were collected from 133 transplant centers and analyzed retrospectively (16,641 liver transplants in 14,515 children). Data were analyzed according to three successive periods (A, before 2000; B, 2000-2009; and C, since 2010), studying donor and graft characteristics and graft outcome. The use of living donors steadily increased from A to C (A, n = 296 [7%]; B, n = 1131 [23%]; and C, n = 1985 [39%]; p = 0.0001). Overall, the 5-year graft survival rate has improved from 65% in group A to 75% in group B (p < 0.0001) and to 79% in group C (B versus C, p < 0.0001). Graft half-life was 31 years, overall; it was 41 years for children who survived the first year after transplant. The late annual graft loss rate in teenagers is higher than that in children aged <12 years and similar to that of young adults. No evidence for accelerated graft loss after age 18 years was found. CONCLUSIONS: Pediatric liver transplantation has reached a high efficacy as a cure or treatment for severe liver disease in infants and children. Grafts that survived the first year had a half-life similar to standard human half-life. Transplantation before or after puberty may be the pivot-point for lower long-term outcome in children. Further studies are necessary to revisit some old concepts regarding transplant benefit (survival time) for small children, the role of recipient pathophysiology versus graft aging, and risk at transition to adult age.

RESUMO

BACKGROUND & AIMS: The concept of benchmarking is established in the field of transplant surgery; however, benchmark values for donation after circulatory death (DCD) liver transplantation are not available. Thus, we aimed to identify the best possible outcomes in DCD liver transplantation and to propose outcome reference values. METHODS: Based on 2,219 controlled DCD liver transplantations, collected from 17 centres in North America and Europe, we identified 1,012 low-risk, primary, adult liver transplantations with a laboratory MELD score of ≤20 points, receiving a DCD liver with a total donor warm ischemia time of ≤30 minutes and asystolic donor warm ischemia time of ≤15 minutes. Clinically relevant outcomes were selected and complications were reported according to the Clavien-Dindo-Grading and the comprehensive complication index (CCI). Corresponding benchmark cut-offs were based on median values of each centre, where the 75th-percentile was considered. RESULTS: Benchmark cases represented between 19.7% and 75% of DCD transplantations in participating centres. The 1-year retransplant and mortality rates were 4.5% and 8.4% in the benchmark group, respectively. Within the first year of follow-up, 51.1% of recipients developed at least 1 major complication (≥Clavien-Dindo-Grade III). Benchmark cut-offs were ≤3 days and ≤16 days for ICU and hospital stay, ≤66% for severe recipient complications (≥Grade III), ≤16.8% for ischemic cholangiopathy, and ≤38.9 CCI points 1 year after transplant. Comparisons with higher risk groups showed more complications and impaired graft survival outside the benchmark cut-offs. Organ perfusion techniques reduced the complications to values below benchmark cut-offs, despite higher graft risk. CONCLUSIONS: Despite excellent 1-year survival, morbidity in benchmark cases remains high. Benchmark cut-offs targeting morbidity parameters offer a valid tool to assess the protective value of new preservation technologies in higher risk groups and to provide a valid comparator cohort for future clinical trials. LAY SUMMARY: The best possible outcomes after liver transplantation of grafts donated after circulatory death (DCD) were defined using the concept of benchmarking. These were based on 2,219 liver transplantations following controlled DCD donation in 17 centres worldwide. Donor and recipient combinations with higher risk had significantly worse outcomes. However, the use of novel organ perfusion technology helped high-risk patients achieve similar outcomes as the benchmark cohort.

RESUMO

BACKGROUND & AIMS: Donor death is the most serious complication of living liver donation but is reported rarely. We investigated the actual mortality of living liver donors (LLDs) compared with matched control groups based on analysis of the Korean National Health Insurance Services (NHIS) database. METHODS: This cohort study included 12,372 LLDs who donated a liver graft between 2002 and 2018, and were registered in the Korean Network for Organ Sharing. They were compared to 3 matched control groups selected from the Korean NHIS and comprising a total of 123,710 individuals: healthy population (Group I); general population without comorbidities (Group II); and general population with comorbidities (Group III). RESULTS: In this population, 78.5% of living liver donors were 20-39 years old, and 64.7% of all donors were male. Eighty-nine donors (0.7%) in the LLD group died (68 males and 21 females), a mortality rate (/1,000 person-years) of 0.91 (0.74-1.12). Mortality rate ratio and the adjusted hazard ratio of the LLD group was 2.03 (1.61-2.55) and 1.71 (1.31-2.25) compared to Control Group I, 0.75 (0.60-0.93) and 0.63 (0.49-0.82) compared to Control Group II, and 0.58 (0.46-0.71) and 0.49 (0.39-0.60) compared to Control Group III. LLD group, depression, and lower income were risk factors for adjusted mortality. The incidence of liver failure, depression, cancer, diabetes, hypertension, brain infarction, brain hemorrhage, and end-stage renal disease in the LLD group was significantly higher than in Control Group I. CONCLUSIONS: Outcomes of the LLD group were worse than those of the matched healthy control group despite the small number of deaths and medical morbidities in this group. LLDs should receive careful medical attention for an extended period after donation. LAY SUMMARY: The incidence of mortality, liver failure, depression, cancer, diabetes, hypertension, brain infarction, brain hemorrhage, and end-stage renal disease in the living liver donor group was significantly higher than in the matched healthy group. Careful donor evaluation and selection processes can improve donor safety and enable safe living donor liver transplantation.

RESUMO

BACKGROUND & AIMS: In Italy, since August 2014, liver transplant (LT) candidates with model for end-stage liver disease (MELD) scores ≥30 receive national allocation priority. This multicenter cohort study aims to evaluate time on the waiting list, dropout rate, and graft survival before and after introducing the macro-area sharing policy. METHODS: A total of 4,238 patients registered from 2010 to 2018 were enrolled and categorized into an ERA-1 Group (n = 2,013; before August 2014) and an ERA-2 Group (n = 2,225; during and after August 2014). A Cox proportional hazards model was used to estimate the hazard ratio (HR) of receiving a LT or death between the two eras. The Fine-Gray model was used to estimate the HR for dropout from the waiting list and graft loss, considering death as a competing risk event. A Fine-Gray model was also used to estimate risk factors of graft loss. RESULTS: Patients with MELD ≥30 had a lower median time on the waiting list (4 vs.12 days, p <0.001) and a higher probability of being transplanted (HR 2.27; 95% CI 1.78-2.90; p = 0.001) in ERA-2 compared to ERA-1. The subgroup analysis on 3,515 LTs confirmed ERA-2 (odds ratio 0.56; 95% CI 0.46-0.68; p = 0.001) as a protective factor for better graft survival rate. The protective variables for lower dropouts on the waiting list were: ERA-2, high-volume centers, no competition centers, male recipients, and hepatocellular carcinoma. The protective variables for graft loss were high-volume center and ERA-2, while MELD ≥30 remained related to a higher risk of graft loss. CONCLUSIONS: The national MELD ≥30 priority allocation was associated with improved patient outcomes, although MELD ≥30 was associated with a higher risk of graft loss. Transplant center volumes and competition among centers may have a role in recipient prioritization and outcomes. CLINICAL TRIAL NUMBER: NCT04530240 LAY SUMMARY: Italy introduced a new policy in 2014 to give national allocation priority to patients with a model for end-stage liver disease (MELD) score ≥30 (i.e. very sick patients). This policy has led to more liver transplants, fewer dropouts, and shorter waiting times for patients with MELD ≥30. However, a higher risk of graft loss still burdens these cases. Transplant center volumes and competition among centers may have a role in recipient prioritization and outcomes.

RESUMO

RESUMO Objetivo conhecer o perfil clínico e cirúrgico de pacientes que realizaram ceratoplastia em um hospital universitário. Métodos Trata-se de um estudo observacional analítico, do tipo transversal. Foram avaliadas as fichas de descrição cirúrgica dos prontuários dos pacientes transplantados nos anos de 2019 e 2020, a fim de analisar dados sociais e clínicos. Os dados foram tratados por meio do programa Microsoft Office Excel 2017. As variáveis numéricas foram analisadas com auxílio da estatística descritiva no programa Bioestat versão 5.3 (frequência, porcentagem, média). As informações descritivas foram analisadas qualitativamente. Resultados Foram realizados 167 procedimentos nesse período, notando-se faixa etária média de 45 anos, indivíduos do sexo masculino, receptores de tecidos doados no Pará ou provenientes do Estado do Ceará. Os transplantes foram majoritariamente ópticos, eletivos, com botão corneano doador em média de 8mm e receptor de 7,5mm. Quanto às indicações, a maioria era decorrente de distrofias corneanas, seguidas de leucoma e perfuração do globo ocular, com predominância da técnica cirúrgica penetrante, sutura interrompida e anestesia local. Conclusão O conhecimento desses dados é importante para considerar que o perfil clínico e cirúrgico dos pacientes do hospital estudado se aproxima da realidade nacional, sobretudo na indicação clínica.


ABSTRACT Objective to investigate the clinical and surgical profile of patients who performed keratoplasty in a university hospital. Methods It is a cross-sectional, observational study. The surgical description from the medical records of transplanted patients in the years 2019 and 2020 was assessed to analyze social and clinical data. Data were processed using the Microsoft Office Excel 2017 program. Numerical variables were analyzed using descriptive statistics in the Bioestat program version 5.3. Descriptive information was analyzed qualitatively. Results 167 procedures were performed in this period, with an average age of 45 years old, male individuals, recipients of tissue donated in Pará or sent from the State of Ceará. Transplants were mostly optic, elective, with an average corneal donor button of 8mm and recipient of 7.5mm. As for the indications, most were due to corneal dystrophies, followed by leukoma and perforation of the eyeball, with a predominance of the penetrating surgical technique, interrupted suture, and local anesthesia. Conclusion The knowledge of these data is important to consider that the clinical and surgical profile of patients in the hospital studied is close to the national reality, especially in clinical indication.

RESUMO

ABSTRACT Objective: To outline the epidemiological profile of cornea donors and recipients before reaching queue zero. Methods: Epidemiological study, of quantitative approach, with transversal, analytical design, analyzing database records from the Health Secretary of the State of Ceará, from 2013 to 2015. Results: We obtained 1,558 cornea donors and 2,287 cornea recipients from 2013 to 2015. Most donors were male, capital residents, from 21 to 40 years old. Of donated eyeballs, 14.52% were disposed, due to poor condition, infiltration or positive serology. The recipients were predominantly women over 60 years old. The procedures were mostly elective, due to bullous keratopathy (28%). Regarding emergency transplants, ulcer (38.51%) and retransplant (35.14%) were most prevalent. Predominantly, transplants were funded by the Unified Health System. Conclusion: The majority of patients who were submitted to corneal transplantation are senile, especially females, therefore should be cautiously observed. On the other hand, donors are mainly male and young, reflecting the high number of tragic accidents. The surgery for bullous keratopathy is the most frequent among elective transplants, while the ulcer surgery is the main cause of emergency procedures. The fact that most surgeries were financed by the Unified Health System reflects the importance of this system.


RESUMO Objetivo: Traçar o perfil epidemiológico dos doadores e receptores de córnea antes de atingir a Fila Zero. Métodos: Estudo epidemiológico, de abordagem quantitativa, com delineamento transversal e analítico, analisando registros da base de dados da Secretaria de Saúde do Estado do Ceará, de 2013 a 2015. Resultados: Foram obtidos 1.558 doadores de córnea e 2.287 receptores de córnea, de 2013 a 2015. A maioria dos doadores era homem, procedente da capital, de 21 a 40 anos. Dentre os globos oculares doados, 14,52% foram descartados por má condição, infiltração ou sorologia positiva. Os receptores eram predominantemente mulheres acima de 60 anos de idade. Os procedimentos foram majoritariamente eletivos, devido à ceratopatia bolhosa (28%). Já para transplantes de emergência, a úlcera (38,51%) e o retransplante (35,14%) foram os mais prevalentes. Em geral, os transplantes foram custeados pelo Sistema Único de Saúde. Conclusão: A maioria dos pacientes submetidos a transplantes de córnea foram do grupo etário senil, principalmente do sexo feminino, devendo esse grupo ser observado com cautela. Em contrapartida, os doadores eram, principalmente, homens e jovens, refletindo o alto número de pessoas que morrem devido a acidentes trágicos. A cirurgia de ceratopatia bolhosa foi a mais frequente dentre os transplantes eletivos; já a de úlcera foi a principal causa dos procedimentos de emergência. O fato de a maioria das cirurgias ter sido financiada pelo Sistema Único de Saúde reflete a importância desse sistema.

RESUMO

RESUMO Objetivo: Tendo em vista que o sistema visual representa uma via de contaminação para o novo Corona vírus, a The Global Alliance of Eye Bank Association (GAEBA) divulgou um guideline preconizando a prevenção de transmissão do vírus entre o doadores de tecido ocular e o pacientes receptores, o que resultou em uma diminuição no número de ceratoplastias e aumento de filas de espera para transplantes de córnea (TC) em todo o mundo. Nesse sentido, o presente trabalho tem por objetivo analisar a situação do transplante de córnea (TC) no estado de Alagoas durante o primeiro ano de pandemia da COVID-19. Métodos: Trata-se de um estudo analítico, transversal, observacional utilizando dados provenientes de 3 fontes diferentes: Banco de Tecido Ocular Humano de Alagoas (BTO-AL), Registro Brasileiro de Transplantes (RBT) e Agência Nacional de Vigilância Sanitária (ANVISA). Resultados: Durante os últimos seis anos, foram realizados 284 TCs em Alagoas, segundo dados do Banco de Transplante de Olhos do estado (BTO), já segundo a Registro Brasileiro de Transplantes (RBT) foram realizados 451 TCs. A porcentagem de córneas não oriundas do BTO de Alagoas se mostrou crescente até 2019, porém decresceu em 2020, e no primeiro ano de pandemia , apenas 11,66% da necessidade anual estimada foi atendida, sendo o período com menor número de TCs realizados entre os seis anos analisados na pesquisa. Conclusão: O estudo demonstra o declínio na doação e realização de transplantes de córnea durante o primeiro ano da pandemia da COVID-19 em Alagoas.


ABSTRACT Objective: Considering the visual system is one source of contamination for the new coronavirus, The Global Alliance of Eye Bank Association (GAEBA) released a guideline recommending prevention of virus transmission between eye tissue donors and recipients, which resulted in a reduction of keratoplasties and increase in the waiting lists for corneal transplants worldwide. Hence, this work aims to analyze the situation of corneal transplantation in the state of Alagoas, during the first year of COVID-19 pandemic. Methods: This is an analytical, cross-sectional, observational study using data from 3 different sources: Human Eye Tissue Bank of Alagoas (BTO-AL), Brazilian Transplant Registry (RBT) and National Health Surveillance Agency (ANVISA). Results: During the past six years, 284 corneal transplants were performed in Alagoas, according to data from the Eye Transplant Bank (BTO) of the state, whereas according to the Brazilian Transplant Registry (RBT) 451 corneal transplants were performed. The percentage of corneas not coming from the BTO of Alagoas increased until 2019 but dropped in 2020. In the first year of the pandemic, only 11.66% of estimated annual need was met, and this period had the lowest number of corneal transplants performed out of the six years analyzed in the research. Conclusion: The study demonstrated the decline in donation and performance of corneal transplants during the first year of the COVID-19 pandemic in Alagoas.

RESUMO

Importance: The proportion of living donor kidney transplants from donors unrelated to their recipients is increasing in the US. Objective: To examine the association between donor-recipient biological relationship and allograft survival after living donor kidney transplant. Design, Setting, and Participants: This retrospective cohort study used Organ Procurement and Transplantation Network data on US adult living donor kidney transplants (n = 86 154) performed from January 1, 2000, to December 31, 2014, excluding cases in which recipients previously received a kidney transplant (n = 10 342) or key data were missing (n = 2832). Last follow-up was March 20, 2020. Exposures: Donor-recipient biological relationship. Main Outcomes and Measures: The primary outcome was death-censored allograft failure. Univariate and multivariable time-to-event analyses were performed for death-censored allograft failure for the overall cohort, then separately for recipients with and without primary diagnoses of cystic kidney disease and for transplants from African American and non-African American donors. Results: Among the 72 980 transplant donor and recipients included in the study (median donor age, 41 years; interquartile range [IQR], 32-50 years; 43 990 [60%] female; 50 014 [69%] White), 43 174 (59%) donors and recipients were biologically related and 29 806 (41%) were unrelated. Donors related to their recipients were younger (median [IQR] age, 39 [31-48] vs 44 [35-52] years) and less likely to be female (24 848 [58%] vs 19 142 [64%]) or White (26 933 [62%] vs 23 081 [77%]). Recipients related to their donors were younger (median [IQR] age, 48 [34-58] vs 50 [40-58] years), more likely to be female (18 035 [42%] vs 10 530 [35%]), and less likely to have cystic kidney disease (2530 [6%] vs 4600 [15%]). Related pairs had fewer HLA mismatches overall (median [IQR], 3 [2-3] vs 5 [4-5]). After adjustment for HLA mismatches, donor and recipient characteristics, and transplant era, donor-recipient biological relationship was associated with higher death-censored allograft failure (hazard ratio, 1.05; 95% CI, 1.01-1.10; P = .03). When stratified by primary disease, this association persisted only for recipients without cystic kidney disease. When stratified by donor race, this association persisted only for transplants from African American donors. Conclusions and Relevance: In this cohort study, living donor kidney transplants from donors biologically related to their recipients had higher rates of allograft failure than transplants from donors unrelated to their recipients after HLA matching was accounted for. Further study is needed to determine which genetic or socioenvironmental factors are associated with this finding.

RESUMO

Importance: Historically, deceased organ donation was lower among Black compared with White populations, motivating efforts to reduce racial disparities. The overarching effect of these efforts in Black and other racial/ethnic groups remains unclear. Objective: To examine changes in deceased organ donation over time. Design, Setting, and Participants: This population-based cohort study used data from January 1, 1999, through December 31, 2017, from the Scientific Registry of Transplant Recipients to quantify the number of actual deceased organ donors, and from the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research Detailed Mortality File to quantify the number of potential donors (individuals who died under conditions consistent with organ donation). Data were analyzed from December 2, 2019, to May 14, 2020. Exposures: Race and ethnicity of deceased and potential donors. Main Outcomes and Measures: For each racial/ethnic group and year, a donation ratio was calculated as the number of actual deceased donors divided by the number of potential donors. Direct age and sex standardization was used to allow for group comparisons, and Poisson regression was used to quantify changes in donation ratio over time. Results: A total of 141 534 deceased donors and 5 268 200 potential donors were included in the analysis. Among Black individuals, the donation ratio increased 2.58-fold from 1999 to 2017 (yearly change in adjusted incidence rate ratio [aIRR], 1.05; 95% CI, 1.05-1.05; P < .001). This increase was significantly greater than the 1.60-fold increase seen in White individuals. Nevertheless, substantial racial differences remained, with Black individuals still donating at only 69% the rate of White individuals in 2017 (P < .001). Among other racial minority populations, changes were less drastic. Deceased organ donation increased 1.80-fold among American Indian/Alaska Native and 1.40-fold among Asian or Pacific Islander populations, with substantial racial differences remaining in 2017 (American Indian/Alaska Native population donation at 28% and Asian/Pacific Islander population donation at 85% the rate of the White population). Deceased organ donation differences between Hispanic/Latino and non-Hispanic/Latino populations increased over time (4% lower in 2017). Conclusions and Relevance: The findings of this cohort study suggest that differences in deceased organ donation between White and some racial minority populations have attenuated over time. The greatest gains were observed among Black individuals, who have been the primary targets of study and intervention. Despite improvements, substantial differences remain, suggesting that novel approaches are needed to understand and address relatively lower rates of deceased organ donation among all racial minorities.

RESUMO

OBJECTIVE: Despite growing evidence of comparable outcomes in recipients of donation after circulatory death and donation after brain death donor lungs, donation after circulatory death allografts continue to be underused nationally. We examined predictors of nonuse. METHODS: All donors who donated at least 1 organ for transplantation between 2005 and 2019 were identified in the United Network for Organ Sharing registry and stratified by donation type. The primary outcome of interest was use of pulmonary allografts. Organ disposition and refusal reasons were evaluated. Multivariable regression modeling was used to assess the relationship between donor factors and use. RESULTS: A total of 15,458 donation after circulatory death donors met inclusion criteria. Of 30,916 lungs, 3.7% (1158) were used for transplantation and 72.8% were discarded primarily due to poor organ function. Consent was not requested in 8.4% of donation after circulatory death offers with donation after circulatory death being the leading reason (73.4%). Nonuse was associated with smoking history (P < .001), clinical infection with a blood source (12% vs 7.4%, P = .001), and lower PaO2/FiO2 ratio (median 230 vs 423, P < .001). In multivariable regression, those with PaO2/FiO2 ratio less than 250 were least likely to be transplanted (adjusted odds ratio, 0.03; P < .001), followed by cigarette use (0.28, P < .001), and donor age >50 (0.75, P = .031). Recent transplant era was associated with significantly increased use (adjusted odds ratio, 2.28; P < .001). CONCLUSIONS: Nontransplantation of donation after circulatory death lungs was associated with potentially modifiable predonation factors, including organ procurement organizations' consenting behavior, and donor factors, including hypoxemia. Interventions to increase consent and standardize donation after circulatory death donor management, including selective use of ex vivo lung perfusion in the setting of hypoxemia, may increase use and the donor pool.

RESUMO

INTRODUCTION: The current pool of organs available for transplantation does not cover requirements, for this reason non-standard risk donors need to be incorporated into the pool. In this way, donors with small renal tumour are considered for transplantation after bench tumour excision. The aim of our study was to analyse our experience in using these grafts for transplantation. MATERIALS AND METHODS: Retrospective analysis from our prospective accrued database of donors with incidental renal mass used for kidney transplantation between January 2007 and August 2018. RESULTS: Twenty kidney transplantations were performed, thirteen cases received the affected kidney (after tumour removal) and seven the contralateral kidney; from six living and eleven deceased donors. Donor and recipient median age was 58 years (range 22-82) and 56.5 years (range 38-74), respectively. Mean tumour diameter was 12.7 mm (SD 9.5). Tumours resulted in two benign lesions and fifteen renal cell carcinoma. Surgical margins were negative. Two cases presented with bleeding after reperfusion was solved without repercussion. One case presented with immediate vein thrombosis. None of them present delayed graft function. After a 69 month follow-up none of the donors or the recipients presented tumour recurrence. CONCLUSIONS: Kidneys with small incidental tumours seem to be a good option for kidney transplantation in selected patients after bench surgery excision with good functional and oncologic results. More studies and longer follow-up are needed to confirm these results.

RESUMO

Importance: Organ transplant is a life-saving procedure for patients with end-stage organ failure. In the US, organ procurement organizations (OPOs) are responsible for the evaluation and procurement of organs from donors who have died; however, there is controversy regarding what measures should be used to evaluate their performance. Objective: To evaluate OPO performance metrics using combined mortality and donation data and quantify the associations of population demographics with donation metrics. Design, Setting, and Participants: This national cohort study includes data from the US organ transplantation system from January 2008 through December 2017. All individuals who died within the US, as reported by the National Death index, were included. Exposures: Death, organ donation, and donation eligibility. Main Outcomes and Measures: Evaluation of the variation in donation metrics and the use of ineligible donors by OPO and demographic subgroup. Results: This study included 17 501 742 deaths and 75 769 deceased organ donors (45 040 men [59.4%]; 51 908 White individuals [68.5%]). Of these donors, 15 857 (20.9%) were not eligible, as defined by the OPOs. The median donation metrics by OPO were 0.004 (range, 0.002-0.012) donors per death, 0.89 (range, 0.68-1.30) donors per eligible death, and 0.72 (range, 0.57-0.86) eligible donors per eligible death. The OPOs in the upper quartile of the overall eligible donors per eligible death metric were in the upper quartile of annual rankings on 90 of 140 occasions (64.3%). There was little overlap in top-performing OPOs between metrics; an OPO in the upper quartile for 1 metric was also in the upper quartile for the other metrics on 37 of 570 occasions (6.5% of the time). The median donor eligibility rate, defined as the number of eligible donors per donor, was 0.79 (range, 0.61-0.95) across OPOs. Age (eg, 65 to 84 years, coefficient, -0.55 [SE, 0.03]; P < .001; vs those aged 18 to 34 years), sex (male individuals, -0.09 [SE, 0.02]; P < .001; vs female individuals), race (eg, Black individuals, 0.35 [SE, 0.02]; P < .001; vs White individuals), cause of death (eg, central nervous system tumor, 0.48 [SE, 0.08]; P < .001; vs anoxia), year (eg, 2016-2017: -0.10 [SE, 0.03]; P < .001; vs 2008-2009), and OPO were associated with the use of ineligible donors; OPO was a significant factor associated with performance in all metrics (χ256, 500.5; P < .001; coefficient range across individual OPOs, -0.15 [SE, 0.09] to 0.75 [SE, 0.09]), even after accounting for population differences. Female and non-White individuals were significantly less likely to be used as ineligible donors. Conclusions and Relevance: We demonstrate significant variability in OPO performance rankings, depending on which donation metric is used. There were significant differences in OPO performance, even after accounting for differences in potential donor populations. Our data suggest significant variation in use of ineligible donors among OPOs, a source for increased donors. The performance of OPOs should be evaluated using a range of donation metrics.

RESUMO

Resumen La donación de órganos en Chile es insuficiente, con una tasa histórica de alrededor de seis donantes por millón de habitantes. Las reformas legales, mejoras organizacionales y campañas comunicacionales han permitido hacer del año 2019 el más exitoso en cuanto a donación de órganos y trasplantes. El trasplante hepático en Chile fue realizado por primera vez en el año 1969 en el Hospital Naval de Valparaíso, falleciendo el receptor precozmente. El primer trasplante exitoso fue realizado en el año 1985 en el Hospital Militar de Santiago. Desde esa fecha hasta la actualidad se han realizado 1.812 trasplantes de hígado, el 43,6% en hospitales universitarios, el 35,1% en clínicas privadas y un 21,5% en hospitales estatales. El 23,1% en la Pontificia Universidad Católica (PUC), el 20,6% en el Hospital Clínico de la Universidad de Chile (HCUCH), el 15,9% en el Hospital Luis Calvo Mackenna (HLCM), el 15,9% en Clínica Las Condes (CLC), el 14,3% en Clínica Alemana de Santiago (CA), el 5,6% en el Hospital del Salvador (HdS), 2% en Clínica Dávila (CD), 2% en el Sanatorio Alemán de Concepción (SA) y 0,9% en Clínica Santa María (CSM) De este total, 455 son en pacientes pediátricos, de ellos 63,3% en Hospital Luis Calvo Mackenna el 21,1% en la Clínica Las Condes el 7,7% en la Pontificia Universidad Católica de Chile, el 6,4% en la Clínica Alemana y 1,5% en el Sanatorio Alemán. Desde el 2015, aproximadamente el 80% de los trasplantes pediátricos se realizan en el HLCM. Sobrevidas reportadas en adultos van del 75% a 85% al año y de 75% a 92% al año en pacientes pediátricos dependiendo el período. Hay centros que nunca han reportado sus resultados. Se espera mejorar la educación en pro de una sociedad proclive en la donación, mejorar la organización de detección, mantención y procuramiento, aumentar la utilización de órganos, potenciar la utilización los de donantes cadáveres, con técnica Split o hígado dividido y, mientras no tengamos un sistema de donación que dé cuenta de las necesidades del país, mantener los programas de donante vivo. Finalmente debe motivarse a generaciones jóvenes para que se dediquen a esta importante actividad.


Organ donation in Chile is insufficient, with a historical rate of six donors per million inhabitants. Legal reforms, organizational improvements, and communications campaigns have made 2019 the most successful year in terms of organ donations and transplants. The first liver transplant in Chile was performed in 1969 at the Naval Hospital in Valparaíso. However, the patient passed away shortly after. The first successful transplant was performed in 1985 at the Militar Hospital in Santiago. As of that date to present day, 1.812 liver transplants have been performed: 43.6% of these in university hospitals, 35.1% in private clinics, and 21.5% in state hospitals. Of these, 23.1% were performed at the Pontificia Universidad Católica de Chile (PUC), 20.6% at the Universidad de Chile Clinical Hospital (HCUCH), 15.9% at the Luis Calvo Mackenna Hospital (HLCM), 15.9% at the Las Condes Clinic (CLC), 14.3% at the Alemana Clinic in Santiago (CA), 5.6% at the del Salvador Hospital (HdS), 2% at the Dávila Clinic (CD), 2% at the Alemán Sanatorium in Concepción (SA), and 0.9% at the Santa María Clinic (CSM). Of this total, 455 correspond to pediatric patients. Of these patients, 63.3% were at the Luis Calvo Mackenna Hospital, 21.1% at the Las Condes Clinic, 7.7% at the Pontificia Universidad Católica de Chile, 6.4% at the Alemana Clinic, and 1.5% at the Alemán Sanatorium. Since 2015, approximately 80% of pediatric transplants are performed at the HLCM. Reported one-year survival range from 75% to 85% in adults and 75% to 92% in pediatric patients per year, depending on the period. Some centers have never reported their results. It is expected that education of a society prone to organ donation improves, as well as improving the detection, maintenance, and procurement of potential donors, increasing the utilization of organs, enhancing the utilization of organs from deceased donors with Split technique, and, while we are building towards a donation system that responds to the needs of the nation, upholding live donor programs. Finally, younger generations are to be motivated so that they dedicate themselves to this important activity.

RESUMO

Public Health Service increased risk donor kidneys are discarded 50% more often than nonincreased risk donor kidneys despite equivalent patient and graft survival outcomes. Patient and provider biases as well as challenges in risk interpretation contribute to the underuse of increased risk donor organs. As the ultimate decision to accept or reject an increased risk donor organ results from the patient-provider conversation, there is an opportunity to improve this dialogue. This report introduces the best-case/worst-case communication guide for structuring high-stake conversations on increased risk kidney offers between transplant providers and their patients. Through best case/worst case, providers focus on eliciting patient values and long-term goals. The patient's unique context can then inform an individualized discussion of "best," "worst," and "most likely" outcomes and support the provider's ultimate recommendation. Transplant providers are encouraged to adopt this communication strategy to enhance shared decision-making and improve patient outcomes.
