An Inventory of Deceased Donor Family Care and Contact Between Donor Families and Recipients in 15 European Countries.

Families of organ donors play an important role in the deceased organ donation process. The aim of this study was to gain insight into donor family care by creating an inventory of practice in various European countries. A questionnaire about donor family care and contact between donor families and recipients was developed. Representatives of the organ donor professionals of 15 European countries responded (94%). The donor coordinator plays a key role in care for the donor family. All countries provide information about the donation results to the families, although diminished due to privacy laws. Anonymous written contact between donor families and recipients is possible in almost all countries and direct contact in only a few. Remembrance ceremonies exist in most countries. Half of the respondents thought the aftercare could improve. This first inventory shows that differences exist between countries, depending on the organisation of the donation process, the law and the different role of the professionals. Direct contact between donor families and recipients is rarely supported by the donation organisation. To date there has been limited research about the experience of donor family aftercare and we would urge all donation organisations to consider this as a priority area.

Global Kidney Exchange: opportunity or exploitation? An ELPAT/ESOT appraisal.

This paper addresses ethical, legal, and psychosocial aspects of Global Kidney Exchange (GKE). Concerns have been raised that GKE violates the nonpayment principle, exploits donors in low- and middle-income countries, and detracts from the aim of self-sufficiency. We review the arguments for and against GKE. We argue that while some concerns about GKE are justified based on the available evidence, others are speculative and do not apply exclusively to GKE but to living donation more generally. We posit that concerns can be mitigated by implementing safeguards, by developing minimum quality criteria and by establishing an international committee that independently monitors and evaluates GKE's procedures and outcomes. Several questions remain however that warrant further clarification. What are the experiences and views of recipients and donors participating in GKE? Who manages the escrow funds that have been put in place for donor and recipients? What procedures and safeguards have been put in place to prevent corruption of these funds? What are the inclusion criteria for participating GKE centers? GKE provides opportunity to promote access to donation and transplantation but can only be conducted with the appropriate safeguards. Patients' and donors' voices are missing in this debate.

Donation after circulatory death today: an updated overview of the European landscape.

Donation after circulatory death (DCD) has become an accepted practice in many countries and remains a focus of intense interest in the transplant community. The present study is aimed at providing a description of the current situation of DCD in European countries. Specific questionnaires were developed to compile information on DCD practices, activities and post-transplant outcomes. Thirty-five countries completed the survey. DCD is practiced in 18 countries: eight have both controlled DCD (cDCD) and uncontrolled DCD (uDCD) programs, 4 only cDCD and 6 only uDCD. All these countries have legally binding and/or nonbinding texts to regulate the practice of DCD. The no-touch period ranges from 5 to 30 min. There are variations in ante and post mortem interventions used for the practice of cDCD. During 2008-2016, the highest DCD activity was described in the United Kingdom, Spain, Russia, the Netherlands, Belgium and France. Data on post-transplant outcomes of patients who receive DCD donor kidneys show better results with grafts obtained from cDCD versus uDCD donors. In conclusion, DCD is becoming increasingly accepted and performed in Europe, importantly contributing to the number of organs available and providing acceptable post-transplantation outcomes.

Appointing nurses trained in organ donation to improve family consent rates.

BACKGROUND: One of the most important bottlenecks in the organ donation process worldwide is the high family refusal rate. AIMS AND OBJECTIVES: The main aim of this study was to examine whether family guidance by trained donation practitioners increased the family consent rate for organ donation. DESIGN: This was a prospective intervention study. METHODS: Intensive and coronary care unit nurses were trained in communication about donation (ie, trained donation practitioners) in two hospitals. The trained donation practitioners were appointed to guide the families of patients with a poor medical prognosis. When the patient became a potential donor, the trained donation practitioner was there to guide the family in making a well-considered decision about donation. We compared the family consent rate for donation with and without the guidance of a trained donation practitioner. RESULTS: The consent rate for donation with guidance by a trained donation practitioner was 58.8% (20/34), while the consent rate without guidance by a trained donation practitioner was 41.4% (41/99, P = 0.110) in those patients where the family had to decide on organ donation. CONCLUSIONS: Our data suggest that family guidance by a trained donation practitioner could benefit consent rates for organ donation. RELEVANCE TO CLINICAL PRACTICE: Trained nurses play an important role in supporting the families of patients who became potential donors to guide them through the decision-making process after organ donation request.

Physician Experiences with Communicating Organ Donation with the Relatives: A Dutch Nationwide Evaluation on Factors that Influence Consent Rates.

BACKGROUND: The aim of this nationwide observational study is to identify modifiable factors in communication about organ donation that influence family consent rates. METHODS: Thirty-two intensivists specialized in organ donation systematically evaluated all consecutive organ donation requests with physicians in the Netherlands between January 2013 and June 2016, using a standardized questionnaire. RESULTS: Out of 2528 consecutive donation requests, 2095 (83%) were evaluated with physicians. The questionnaires of patients registered with consent or objection in the national donor registry were excluded from analysis. Only those questionnaires, in which the family had to make a decision about donation, were analyzed (n = 1322). Independent predictors of consent included: requesting organ donation during the conversation about futility of treatment (OR 1.8; p = 0.004), understanding of the term 'brain death' by the family (OR 2.4; p = 0.002), and consulting a donation expert prior to the donation request (OR 3.4; p < 0.001). CONCLUSIONS: Our study showed that decoupling the organ donation conversation from the conversation about futility of treatment was associated with lower family consent rates. Comprehension of the concept of brain death by the family and consultation with a transplant coordinator before the organ donation request by the physician could positively influence consent rates.

Abdominal organ procurement in the Netherlands - an analysis of quality and clinical impact.

Between March 2012 and August 2013, 591 quality forms were filled out for abdominal organs in the Netherlands. In 133 cases (23%), there was a discrepancy between the evaluation from the procuring and transplanting surgeons. Injuries were seen in 148 (25%) organs of which 12 (2%) led to discarding of the organ: one of 133 (0.8%) livers, five of 38 (13%) pancreata and six of 420 (1.4%) kidneys (P < 0.001). Higher donor BMI was a risk factor for procurement-related injury in all organs (OR: 1.06, P = 0.011) and donor after cardiac death (DCD) donation in liver procurement (OR: 2.31, P = 0.034). DCD donation is also associated with more pancreata being discarded due to injury (OR: 10.333, P = 0.046). A higher procurement volume in a centre was associated with less injury in pancreata (OR = -0.95, P = 0.013) and kidneys (OR = -0.91, P = 0.012). The quality form system efficiently monitors the quality of organ procurement. Although there is a relatively high rate of organ injury, the discard rate is low and it does not significantly affect 1-year graft survival for any organ. We identified higher BMI as a risk factor for injury in abdominal organs and DCD as a risk factor in livers. A higher procurement volume is associated with fewer injuries.

Allocation and matching in kidney exchange programs.

Living donor kidney transplantation is the preferred treatment for patients suffering from end-stage renal disease. To alleviate the shortage of kidney donors, many advances have been made to improve the utilization of living donors deemed incompatible with their intended recipient. The most prominent of these advances is kidney paired donation (KPD), which matches incompatible patient-donor pairs to facilitate a kidney exchange. This review discusses the various approaches to matching and allocation in KPD. In particular, it focuses on the underlying principles of matching and allocation approaches, the combination of KPD with other strategies such as ABO incompatible transplantation, the organization of KPD, and important future challenges. As the transplant community strives to balance quantity and equity of transplants to achieve the best possible outcomes, determining the right long-term allocation strategy becomes increasingly important. In this light, challenges include making full use of the various modalities that are now available through integrated and optimized matching software, encouragement of transplant centers to fully participate, improving transplant rates by focusing on the expected long-run number of transplants, and selecting uniform allocation criteria to facilitate international pools.

Imprecise definitions of starting points in retrospectively reviewing potential organ donors causes confusion: call for a reproducible method like 'imminent brain death'.

Low donor supply and the high demand for transplantable organs is an international problem. The efficiency of organ procurement is often expressed by donor conversion rates (DCRs). These rates differ among countries, but a uniform starting point for defining a potential heart-beating donor is lacking. Imprecise definitions cause confusion; therefore, we call for a reproducible method like imminent brain death (IBD), which contains criteria in detail to determine potential heart-beating donors. Medical charts of 4814 patients who died on an ICU in Dutch university hospitals between January 2007 and December 2009 were reviewed for potential heart-beating donors. We compared two starting points: 'Severe Brain Damage' (SBD) (old definition) and IBD (new definition), which differ in the number of absent brainstem reflexes. Of the potential donors defined by IBD 45.6% fulfilled the formal brain death criteria, compared with 33.6% in the larger SBD group. This results in a higher DCR in the IBD group (40% vs. 29.5%). We illustrated important differences in DCRs when using two different definitions, even within one country. To allow comparison among countries and hospitals, one universal definition of a potential heart-beating donor should be used. Therefore, we propose the use of IBD.

Hypothermic Machine Perfusion as a National Standard Preservation Method for Deceased Donor Kidneys.

BACKGROUND: Recently, continuous nonoxygenated hypothermic machine perfusion (HMP) has been implemented as standard preservation method for deceased donor kidneys in the Netherlands. This study was designed to assess the effect of the implementation of HMP on early outcomes after transplantation. METHODS: Kidneys donated in the Netherlands in 2016 and 2017 were intended to be preserved by HMP. A historical cohort (2010-2014) preserved by static cold storage was chosen as the control group. Primary outcome was delayed graft function (DGF). Additional analyses were performed on safety, graft function, and survival up until 2 y after transplantation. RESULTS: Data were collected on 2493 kidneys. Analyses showed significantly more donation after circulatory death, preemptive transplantation, and retransplants in the project cohort. Of the 681 kidneys that were transplanted during the project, 81% were preserved by HMP. No kidneys were discarded due to HMP-related complications. DGF occurred in 38.2% of the project cohort versus 43.7% of the historical cohort (P < 0.001), with a significantly shorter duration within the project cohort (7 versus 9 d, P = 0.003). Multivariate regression analysis showed an odds ratio of 0.69 (95% confidence interval, 0.553-0.855) for the risk of DGF when using HMP compared with cold storage (P = 0.001). There was no significant difference in kidney function, graft survival, and recipient survival up until 2 y posttransplantation. CONCLUSIONS: This study showed that HMP as a standard preservation method for deceased donor kidneys is safe and feasible. HMP was associated with a significant reduction of DGF.

Current situation of donation after circulatory death in European countries.

The aim of the present study was to describe the current situation of donation after circulatory death (DCD) in the Council of Europe, through a dedicated survey. Of 27 participating countries, only 10 confirmed any DCD activity, the highest one being described in Belgium, the Netherlands and the United Kingdom (mainly controlled) and France and Spain (mainly uncontrolled). During 2000-2009, as DCD increased, donation after brain death (DBD) decreased about 20% in the three countries with a predominant controlled DCD activity, while DBD had increased in the majority of European countries. The number of organs recovered and transplanted per DCD increased along time, although it remained substantially lower compared with DBD. During 2000-2008, 5004 organs were transplanted from DCD (4261 kidneys, 505 livers, 157 lungs and 81 pancreas). Short-term outcomes of 2343 kidney recipients from controlled versus 649 from uncontrolled DCD were analyzed: primary non function occurred in 5% vs. 6.4% (P = NS) and delayed graft function in 50.2% vs. 75.7% (P < 0.001). In spite of this, 1 year graft survival was 85.9% vs. 88.9% (P = 0.04), respectively. DCD is increasingly accepted in Europe but still limited to a few countries. Controlled DCD might negatively impact DBD activity. The degree of utilization of DCD is lower compared with DBD. Short-term results of DCD are promising with differences between kidney recipients transplanted from controlled versus uncontrolled DCD, an observation to be further analyzed.

Appointing 'trained donation practitioners' results in a higher family consent rate in the Netherlands: a multicenter study.

The consent process for organ and tissue donation is complex, both for families and professionals. To help professionals in broaching this subject we performed a multicenter study. We compared family consent to donation in three hospitals between December 2007 and December 2009. In the intervention hospital, trained donation practitioners (TDP) guided 66 families throughout the time in the ICU until a decision regarding donation had been reached. In the first control hospital, without any family guidance or training, 107 families were approached. In the second control hospital 'hostesses', who were not trained in donation questions, supported 99 families during admittance. A total of 272 families were requested to donate. We primarily compared consent rates, but also asked families about their experiences through a questionnaire. Family consent rate was significantly higher in the intervention hospital: 57.6% (38/66), than in the control hospitals: 34.6% (37/107) and 39.4% (39/99). The 69% response rate to the questionnaire -~5 months after death - showed no confounding variables that could have influenced the consent rate. Appointing TDPs in the intervention hospital to guide families during admittance and the donation decision-making process, results in higher family consent rates.

Organ donation performance in the Netherlands 2005-08; medical record review in 64 hospitals.

BACKGROUND: The Netherlands has a low number of deceased organ donors per million population. As long as there is a shortage of suitable organs, the need to evaluate the donor potential is crucial. Only in this way can bottlenecks in the organ donation process be detected and measures subsequently taken to further improve donation procedures. METHODS: Within a time frame of 4 years, 2005-08, medical charts of all intensive care deaths in 64 hospitals were reviewed by transplant coordinators and donation officers. Data were entered in a web-based application of the Dutch Transplant Foundation, both to identify the number of potential organ donors (including donation after cardiac death), as well as to analyse the reasons for potential donor loss. RESULTS: In total, 23 508 patients died in intensive care units, of which 64% were younger than 76 years. The percentage of all potential organ donors out of the total number of deaths decreased from 8.2% in 2005 to 7.1% in 2008. Donor detection increased from 96% in 2005 to 99% in 2008. Of the potential donors, 17-21% recorded consent and 17-18% recorded objection in the national Donor Register. If the Donor Register was not decisive, the consent rate of families approached for organ donation was 35% in 2005, 29% in 2006, 41% in 2007 and 31% in 2008. The overall conversion rate (the number of actual donors divided by the number of potential donors) was 30%, 26%, 35% and 29% in these years. In the group of potential donor losses, objection by families accounted for about 60% during this study. CONCLUSIONS: This study showed that the maximal number of potential organ donors is about three times higher than the number of effective organ donors. The main reason accounting for approximately 60% of the potential donor losses was the high family refusal rate. The year 2007 showed that a higher percentage of deceased organ donors can be procured from the pool of potential donors. All improvements should focus on decreasing the unacceptably high family refusal rates.

The optimal chain length for kidney paired exchanges: an analysis of the Dutch program.

Living donor kidney exchange programs offer incompatible donor-recipient pairs the opportunity to be transplanted. To increase the number of these transplants, we examined in our actual donor-recipient couples how to reach the maximum number of matches by using different chain lengths. We performed 20 match procedures in which we constructed four different chain lengths: two, up to three, up to four and unlimited. The actual inflow and outflow of donor-recipient couples for each run were taken into consideration in this analysis. The total number of matched pairs increased from 148 pairs for only two-way exchanges to 168 for three-way exchanges. When a chain length of 4 was allowed five extra couples could be matched over a period of 5 years. Unlimited chain length did not significantly affect the results. The optimal chain length for living donor kidney exchange programs is 3. Longer chains with their inherent logistic burden do not lead to significantly more transplants.

A plea for uniform European definitions for organ donor potential and family refusal rates.

Conversion of potential organ donors to actual donors is negatively influenced by family refusals. Refusal rates differ strongly among countries. Is it possible to compare refusal rates in order to be able to learn from countries with the best practices? We searched in the literature for reviews of donor potential and refusal rates for organ donation in intensive care units. We found 14 articles pertinent to this study. There is an enormous diversity among the performed studies. The definitions of potential organ donors and family refusal differed substantially. We tried to re-calculate the refusal rates. This method failed because of the influence caused by the registered will on donation in the Donor Register. We therefore calculated the total refusal rate. This strategy was also less satisfactory considering possible influence of the legal consent system on the approach of family. Because of lack of uniform definitions, we can conclude that the refusal rates for organ donation can not be used for a sound comparison among countries. To be able to learn from well-performing countries, it is necessary to establish uniform definitions regarding organ donation and registration of all intensive care deaths.

Building Kidney Exchange Programmes in Europe-An Overview of Exchange Practice and Activities.

BACKGROUND: Considerable differences exist among the living donor Kidney Exchange Programmes (KEPs) that are in use and being built in Europe, contributing to a variation in the number of living donor transplants (Newsletter Transplant; International figures on donation and transplantation 2016). Efforts of European KEPs to exchange (best) practices and share approaches to address challenges have, however, been limited. METHODS: Experts from 23 European countries, collaborating on the European Network for Collaboration on Kidney Exchange Programmes Cooperation on Science and Technology Action, developed a questionnaire to collect detailed information on the functioning of all existing KEPs in Europe, as well as their opportunities and challenges. Following a comparative analysis, results were synthesized and interpreted by the same experts. RESULTS: The practices, opportunities and challenges reported by 17 European countries reveal that some of the 10 operating programs are mature, whereas others are in earlier stages of development. Over 1300 transplants were performed through existing KEPs up to the end of 2016, providing approximately 8% of their countries' living kidney donations in 2015. All countries report challenges to either initiating KEPs or increasing volumes. Some challenges are shared, whereas others differ because of differences in context (eg, country size, effectiveness of deceased donor program) and ethical and legal considerations (eg, regarding living donation as such, nonrelated donors, and altruistic donation). Transnational initiatives have started in Central Europe, Scandinavia, and Southern Europe. CONCLUSIONS: Exchange of best practices and shared advancement of national programs to address existing challenges, aided by transnational exchanges, may substantially improve access to the most (cost) effective treatment for the increasing number of patients suffering from kidney disease.

Evolution of Deceased Organ Donation Activity Versus Efficiency Over a 15-year Period: An International Comparison.

BACKGROUND: The donation rate (DR) per million population is not ideal for an efficiency comparison of national deceased organ donation programs. The DR does not account for variabilities in the potential for deceased donation which mainly depends on fatalities from causes leading to brain death. In this study, the donation activity was put into relation to the mortality from selected causes. Based on that metric, this study assesses the efficiency of different donation programs. METHODS: This is a retrospective analysis of 2001 to 2015 deceased organ donation and mortality registry data. Included are 27 Council of Europe countries, as well as the United States. A donor conversion index (DCI) was calculated for assessing donation program efficiency over time and in international comparisons. RESULTS: According to the DCI and of the countries included in the study, Spain, France, and the United States had the most efficient donation programs in 2015. Even though mortality from the selected causes decreased in most countries during the study period, differences in international comparisons persist. This indicates that the potential for deceased organ donation and its conversion into actual donation is far from being similar internationally. CONCLUSIONS: Compared with the DR, the DCI takes into account the potential for deceased organ donation, and therefore is a more accurate metric of performance. National donation programs could optimize performance by identifying the areas where most potential is lost, and by implementing measures to tackle these issues.

Surgical quality in organ procurement during day and night: an analysis of quality forms.

OBJECTIVES: To analyse a potential association between surgical quality and time of day. DESIGN: A retrospective analysis of complete sets of quality forms filled out by the procuring and accepting surgeon on organs from deceased donors. SETTING: Procurement procedures in the Netherlands are organised per region. All procedures are performed by an independent, dedicated procurement team that is associated with an academic medical centre in the region. PARTICIPANTS: In 18 months' time, 771 organs were accepted and procured in The Netherlands. Of these, 17 organs were declined before transport and therefore excluded. For the remaining 754 organs, 591 (78%) sets of forms were completed (procurement and transplantation). Baseline characteristics were comparable in both daytime and evening/night-time with the exception of height (p=0.003). PRIMARY OUTCOME MEASURE: All complete sets of quality forms were retrospectively analysed for the primary outcome, procurement-related surgical injury. Organs were categorised based on the starting time of the procurement in either daytime (8:00-17:00) or evening/night-time (17:00-8:00). RESULTS: Out of 591 procured organs, 129 organs (22%) were procured during daytime and 462 organs (78%) during evening/night-time. The incidence of surgical injury was significantly lower during daytime; 22 organs (17%) compared with 126 organs (27%) procured during evening/night-time (p=0.016). This association persists when adjusted for confounders. CONCLUSIONS: This study shows an increased incidence of procurement-related surgical injury in evening/night-time procedures as compared with daytime. Time of day might (in)directly influence surgical performance and should be considered a potential risk factor for injury in organ procurement procedures.

A highly efficient living donor kidney exchange program for both blood type and crossmatch incompatible donor-recipient combinations.

BACKGROUND: Lack of deceased donors for kidney transplant patients in the Netherlands encouraged alternative options to expand the living donor pool for recipients who have a willing donor but cannot donate directly because of a positive crossmatch or ABO blood type incompatibility. A national donor kidney exchange was considered as a possible solution. METHODS: From January 2004 until June 2006, 146 couples from seven kidney transplantation centers were enrolled and participated in 10 match procedures. The Dutch Transplant Foundation was responsible for the allocation and the National Reference Laboratory for Histocompatibility in Leiden performed all the serological crossmatches. RESULTS: For 72 out of the 146 (49%) donor-recipient combinations, a match was found. The success rate in the positive crossmatch group was significantly (P = 0.0015) higher than in the ABO-incompatible group (44/69 vs. 28/77); median panel reactive antibodies of the matched recipients in the positive crossmatch group was 38% (0-100) and in the ABO-incompatible group 0% (0-27; P < 0.001). We were least successful for ABO blood type incompatible pairs with blood type O recipients, but for 9/53 (17%) there were possibilities. These nine blood type incompatible pairs were coupled to nine positive crossmatch pairs, which reflects the efficiency of combining the two categories of donor-recipient combinations into one program. CONCLUSION: The donor kidney exchange program in the Netherlands, in which all seven kidney transplantation centers participated, proved to be a successful program to expand the number of living donor kidney transplantations.

Non-heart-beating donor kidneys in the Netherlands: allocation and outcome of transplantation.

BACKGROUND: Since February 1, 2001, kidneys from both heart-beating (HB) and non-heart-beating (NHB) donors in The Netherlands have been indiscriminately allocated through the standard renal-allocation system. METHODS: Renal function and allograft-survival rate for kidneys from NHB and HB donors were compared at 3 and 12 months. RESULTS: The outcomes of 276 renal transplants, 176 from HB donors and 100 from NHB III donors, allocated through the standard renal allocation system, Eurotransplant Kidney Allocation System, and performed between February 1, 2001 and March 1, 2002 were compared. Three months after transplantation, graft survival was 93.7% for HB kidneys and 85.0% for NHB kidneys (P<0.05). At 12 months, graft survival was 92.0% and 83.0%, respectively (P<0.03). Serum creatinine levels in the two groups were comparable at both 3 and 12 months. Multivariate analysis identified previous kidney transplantation (relative risk [RR] 3.33; P<0.005), donor creatinine (RR 1.01; P<0.005), and NHB (RR 2.38; P<0.05) as independent risk factors for transplant failure within 12 months. In multivariate analysis of NHB data, a warm ischemia time (WIT) of 30 minutes or longer (P<0.005; RR 6.16, 95% confidence interval 2.11-18.00) was associated with early graft failure. No difference in 12-month graft survival was seen between HB and NHB kidneys after excluding the kidneys that failed in the first 3 months. CONCLUSION: Early graft failure was significantly more likely in recipients of kidneys from NHB donors. A prolonged WIT was strongly associated with this failure. Standard allocation procedures do not have a negative effect on outcome, and there is no reason to allocate NHB kidneys differently from HB kidneys.
