Organ donation following medical assistance in dying, Part II: a scoping review of existing processes and procedures.

OBJECTIVE: The objective of this review was to collate and summarize the current literature on what is known about organ donation following medical assistance in dying (MAiD). For this second part of a 2-part scoping review, the focus is on the existing procedures and processes for organ donation following MAiD. INTRODUCTION: Organ donation following MAiD is a novel and contentious issue worldwide. To give direction for future research and initiatives, a comprehensive understanding of the available evidence of existing procedures and processes for organ donation following MAiD is needed. INCLUSION CRITERIA: For this review, the population of interest included all individuals who underwent organ donation following MAiD; the concept was defined as procedures and processes involved in organ donation after MAiD; and the context was reports of organ donation following MAiD at home or in any health care setting worldwide. We considered quantitative and qualitative studies, text and opinion papers, gray literature, and unpublished material provided by stakeholders. METHODS: This scoping review was conducted in line with JBI methodology. Published studies were retrieved from MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), PsycINFO (Ovid), Web of Science Core Collection, and Academic Search Complete (EBSCOhost). Gray and unpublished literature included reports from websites and organ donation organizations in Canada, Belgium, and The Netherlands. Two independent reviewers screened all reports (both title and abstract, and full text) against the predetermined inclusion criteria, extracted data, and completed a content analysis. Any disagreements between the 2 reviewers were resolved through discussion or with another reviewer. RESULTS: We included 121 documents across parts I and II, and we report on 107 documents in this second part. The majority of the 107 documents were discussion papers, published in English, and in Canada from 2019 to 2021. In the content analysis, we identified 5 major categories regarding existing procedures and processes of organ donation following MAiD: i) clinical pathways for organ donation following MAiD; ii) organ donation following MAiD and the donor; iii) clinical practice tools for organ donation following MAiD; iv) education and support for health care providers involved in organ donation following MAiD; and v) health care providers' roles and perceptions during organ donation following MAiD. CONCLUSIONS: Findings from this review can be used to provide support and guidance for improvements in procedures and processes, as well as a rich resource for countries currently planning to establish programs for organ donation after MAiD.

Organ donation following medical assistance in dying, Part I: a scoping review of legal and ethical aspects.

OBJECTIVE: The objective of this review was to collate and summarize the current literature on what is known about organ donation following medical assistance in dying (MAiD). Additionally, for this first part of a 2-part scoping review, the focus is on legal and ethical considerations regarding organ donation following MAiD. INTRODUCTION: Organ donation following MAiD is a relatively new procedure that has sparked much debate and discussion. A comprehensive investigation into the legal and ethical aspects related to organ donation following MAiD is needed to inform the development of safe and ethical practices. INCLUSION CRITERIA: In this review, we included documents that investigated legal and/or ethical issues related to individuals who underwent organ donation following MAiD in any setting (eg, hospital or home) worldwide. We considered quantitative and qualitative studies, text and opinion papers, gray literature, and unpublished material provided by stakeholders. METHODS: This scoping review followed JBI methodology. Published studies were retrieved from databases, including MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), PsycINFO (Ovid), Web of Science Core Collection, and Academic Search Complete (EBSCOhost). Gray and unpublished literature included reports from organ donation organizations in Canada, The Netherlands, and Belgium. Two independent reviewers screened all reports (both by title and abstract and by full text) against the inclusion criteria, extracted data, and completed a content analysis. Disagreements between the 2 reviewers were resolved through discussions among the reviewers and the lead reviewer. RESULTS: We included 121 documents for parts I and II of our scoping review, 89 of which are included in part I. The majority of the 89 documents were discussion papers published in English and in Canada from 2019 to 2021. In the content analysis, we identified 4 major categories regarding ethical and legal aspects of organ donation following MAiD: i) legal definitions, legislation, and guidelines; ii) ethics, dilemmas, and consensus; iii) consent and objection; and iv) public perceptions. We identified the main legislation regulating the practices of organ donation following MAiD in countries where both procedures are permitted, the many ethical debates surrounding this topic (eg, eligibility criteria for organ donation and MAiD, disclosure of donors' and recipients' information, directed organ donation, death determination in organ donation following MAiD, ethical safeguards for organ donation following MAiD), as well as the public perceptions of this process. CONCLUSIONS: Organ donation following MAiD has raised many legal and ethical concerns regarding establishing safeguards to protect patients and families. Despite the ongoing debates around the risks and benefits of this combined procedure, when patients who request MAiD want to donate their organs, this option can help fulfill their last wishes and diminish their suffering, which should be the main reasons to offer organ donation following MAiD.

Is the process of withdrawal of life-sustaining measures in the intensive care unit different for deceased organ donors compared with other dying patients? A secondary analysis of prospectively collected data.

OBJECTIVE: To investigate whether observable differences exist between patterns of withdrawal of life-sustaining measures (WLSM) for patients eligible for donation after circulatory death (DCD) in whom donation was attempted compared with those patients in whom no donation attempts were made. SETTING: Adult intensive care units from 20 centres in Canada, the Czech Republic and the Netherlands. DESIGN: Secondary analysis of quantitative data collected as part of a large, prospective, cohort study (the Death Prediction and Physiology after Removal of Therapy study). PARTICIPANTS: Patients ≥18 years of age who died after a controlled WLSM in an intensive care unit. Patients were classified as not DCD eligible, DCD eligible with DCD attempted or DCD eligible but DCD was not attempted. PRIMARY AND SECONDARY OUTCOME MEASURES: The process of WLSM (timing and type and, if applicable, dosages of measures withdrawn, dosages of analgesics/sedatives) was compared between groups. RESULTS: Of the 635 patients analysed, 85% had either cardiovascular support stopped or were extubated immediately on WLSM. Of the DCD eligible patients, more were immediately extubated at the initiation of WLSM when DCD was attempted compared with when DCD was not attempted (95% vs 61%, p<0.0001). Initiation of WLSM with the immediate cessation of cardiovascular measures or early extubation was associated with earlier time to death, even after adjusting for confounders (OR 2.94, 95% CI 1.39 to 6.23, at 30 min). Other than in a few patients who received propofol, analgesic and sedative dosing after WLSM between DCD attempted and DCD eligible but not attempted patients was not significantly different. All patients died. CONCLUSIONS: Patients in whom DCD is attempted may receive a different process of WLSM. This highlights the need for a standardised and transparent process for end-of-life care across the spectrum of critically ill patients and potential organ donors.

Machine learning determination of motivators of terminal extubation during the transition to end-of-life care in intensive care unit.

Procedural aspects of compassionate care such as the terminal extubation are understudied. We used machine learning methods to determine factors associated with the decision to extubate the critically ill patient at the end of life, and whether the terminal extubation shortens the dying process. We performed a secondary data analysis of a large, prospective, multicentre, cohort study, death prediction and physiology after removal of therapy (DePPaRT), which collected baseline data as well as ECG, pulse oximeter and arterial waveforms from WLST until 30 min after death. We analysed a priori defined factors associated with the decision to perform terminal extubation in WLST using the random forest method and logistic regression. Cox regression was used to analyse the effect of terminal extubation on time from WLST to death. A total of 616 patients were included into the analysis, out of which 396 (64.3%) were terminally extubated. The study centre, low or no vasopressor support, and good respiratory function were factors significantly associated with the decision to extubate. Unadjusted time to death did not differ between patients with and without extubation (median survival time extubated vs. not extubated: 60 [95% CI: 46; 76] vs. 58 [95% CI: 45; 75] min). In contrast, after adjustment for confounders, time to death of extubated patients was significantly shorter (49 [95% CI: 40; 62] vs. 85 [95% CI: 61; 115] min). The decision to terminally extubate is associated with specific centres and less respiratory and/or vasopressor support. In this context, terminal extubation was associated with a shorter time to death.

Outcomes from organ donation following medical assistance in dying: A scoping review.

AIM: To collate and summarize the current international literature on the transplant recipient outcomes of organs from Medical Assistance in Dying (MAiD) donors, as well as the actual and potential impact of organ donation following MAiD on the donation and transplantation system. BACKGROUND: The provision of organ donation following MAiD can impact the donation and transplantation system, as well as potential recipients of organs from the MAiD donor, therefore a comprehensive understanding of the potential and actual impact of organ donation after MAiD on the donation and transplantation systems is needed. DESIGN: Scoping review using the JBI framework. METHODS: We searched for published (MEDLINE, Embase, CINAHL, PsycINFO, Web of Science, and Academic Search Complete), and unpublished literature (organ donation organization websites worldwide). Included references discussed the actual and potential impact of organ donation following MAiD on the donation and transplantation system. All references were screened, extracted and analysed by two independent reviewers. RESULTS: We included 78 references in this review and our finding were summarized across three categories: (1) Impact in the donor pool: (2) statistics on organ donation following MAiD; and (3) potential and actual impact of MAiD on the donation and transplant system. CONCLUSIONS: The potential impact of the MAiD donor on the transplant waiting list is relatively small as this process is still rare, however, due to the current organ shortage worldwide the contribution of this procedure should not be disregarded. Additionally, despite being limited, the existing research provided scanty evidence that organs retrieved from MAiD donors are associated with satisfactory graft function and survival rates and that outcomes from transplant recipients are comparable to those of organs from donation following brain death and may be better than those of organs from other types of donation after circulatory determined death. Still, further studies are required for comprehensive and reliable evidence.

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.

Family overrule of registered refusal to donate organs.

It is well known that families frequently overrule the wishes of dying patients who had previously expressed a wish to donate their organs. Various strategies have been suggested to reduce the frequency of these 'family overrules'. However, the possibility of families overruling a patient's registered decision not to donate has not been discussed in the medical literature, although it is legally possible in some countries. In this article, we provide an ethical analysis of family overrule of a relative's refusal to donate, using the different jurisdictions of the UK, Switzerland, Germany and the Netherlands to provide some context. Despite some asymmetries between overruling consent and overruling refusal, there are some cases in which donation should proceed despite a recorded refusal to do so.

[How does a doctor declare death?] / Hoe stelt een arts de dood vast?

Ward doctors in regular medical departments have to be competent in declaring the death of a patient. The majority of literature on confirmation of death focuses on special circumstances, including intensive care patients and cases involving organ donation. There is no consensus regarding the procedure and criteria for declaration of death in a 'normal' patient on a medical ward. In this article we describe the death criteria, changes that occur in the body following death, and how death can be declared in in a 'normal' patient on a medical ward and in special circumstances.

Conscientious objection to deceased organ donation by healthcare professionals.

In this article, we analyse the potential benefits and disadvantages of permitting healthcare professionals to invoke conscientious objection to deceased organ donation. There is some evidence that permitting doctors and nurses to register objections can ultimately lead to attitudinal change and acceptance of organ donation. However, while there may be grounds for conscientious objection in other cases such as abortion and euthanasia, the life-saving nature of donation and transplantation renders objection in this context more difficult to justify. In general, dialogue between healthcare professionals is a more appropriate solution, and any objections must be justified with a strong rationale in hospitals where such policies are put in place.

European Vignettes in Donation After Circulatory Death.

Donation after circulatory death (DCD) is increasing in Europe, yet there is widespread variability in practice. Insight into actual practice is difficult to acquire simply by analyzing protocols and laws from each individual country. For this reason, the 3 DCD vignettes in this article have been constructed to outline routine and standard DCD practice in the United Kingdom, the Netherlands, and Spain. These imagined vignettes reflect a "typical" case, based on the authors' extensive experience with DCD but are not real patient cases. They are a resource aimed at stimulating discussion regarding European organ donation practice and provide a knowledge bank for those wanting to establish a DCD program in their country. It is our hope that by providing these vignettes, the wider organ donation and transplant community, as well as philosophers and the public, will have a better understanding of what DCD really is and what it really isn't.

Family Over Rules? An Ethical Analysis of Allowing Families to Overrule Donation Intentions.

Millions of people want to donate their organs after they die for transplantation, and many of them have registered their wish to do so or told their family and friends about their decision. For most of them, however, this wish is unlikely to be fulfilled, as only a small number of deaths (1% in the United Kingdom) occur in circumstances where the opportunity to donate organs is possible. Even for those who do die in the "right" way and have recorded their wishes or live in a jurisdiction with a "presumed consent" system, donation often does not go ahead because of another issue: their families refuse to allow donation to proceed. In some jurisdictions, the rate of "family overrule" is over 10%. In this article, we provide a systematic ethical analysis of the family overrule of donation of solid organs by deceased patients, and examine arguments both in favor of and against allowing relatives to "veto" the potential donor's intentions. First, we provide a brief review of the different consent systems in various European countries, and the ramifications for family overrule. Next, we describe and discuss the arguments in favor of permitting donation intentions to be overruled, and then the arguments against doing so. The "pro" arguments are: overrule minimises family distress and staff stress; families need to cooperate for donation to take place; families might have evidence regarding refusal; and failure to permit overrules could weaken trust in the donation system. The "con" arguments are: overrule violates the patient's wishes; the family is too distressed and will regret the decision; overruling harms other patients; and regulations prohibit overrule. We conclude with a general discussion and recommendations for dealing with families who wish to overrule donation. Overall, overrule should only rarely be permitted.

Ethical, legal, and societal issues and recommendations for controlled and uncontrolled DCD.

This report deals with organ retrieval procedures in both controlled and uncontrolled DCD, looking at the ethical, legal, and psychosocial aspects during the different phases of the process. A recently published report by the UK Donation Ethics Committee (UKDEC) has served as an important reference document to outline the steps in the controlled DCD patient-donor pathway (Academy of Medical Royal Colleges. UK Donation Ethics Committee. An ethical framework for controlled donation after circulatory death. December 2011). For uncontrolled DCD, the UKDEC pathway description was adapted. At the 6th International Conference in Organ Donation held in Paris in 2013, an established expert European Working Group reviewed the UKDEC reports, which were then considered along with the available published literature. Along this pathway, the crucial ethical, legal, and psychosocial aspects have been flagged, and relevant recommendations have been formulated based on a consensus of the working group.

[Kidney donor with severe disseminated intravascular coagulation: transplantation however successful]. / Nierdonor met ernstige diffuse intravasale stolling: Toch succesvolle transplantatie.

A 41-year-old male, with no previous medical history, was admitted to our intensive care unit with severe isolated neurotrauma and a Glasgow Coma Scale of E1-M1-V1, mid-dilated unreactive pupils and severe abnormalities on the brain CT-scan. A severe syndrome of disseminated intravascular coagulation (DIC) and non-oliguric renal insufficiency developed. Following clinical and neurophysiological examination the patient was declared brain-dead, and the family gave permission for organ donation. The left kidney was transplanted and functioned well immediately. However, in view of the DIC and renal function disorders the right kidney was not considered usable for transplantation elsewhere. Pathological examination revealed many fibrin thrombi in the glomerular capillaries and acute tubular necrosis. This case supports the view that thrombotic microangiopathy in kidneys of patients with DIS, even with renal function impairment, is not an a priori reason for excluding donation.
