Ethical reflection support for potential organ donors' relatives: A narrative review

BACKGROUND

Even in countries with an opt-out or presumed consent system, relatives have a considerable influence on the post-mortem organ harvesting decision. However, their reflection capacity may be compromised by grief, and they are, therefore, often prone to choose refusal as default option. Quite often, it results in late remorse and dissatisfaction. So, a high-quality reflection support seems critical to enable them to gain a stable position and a long-term peace of mind, and also avoid undue loss of potential grafts. In practice, recent studies have shown that the ethical aspects of reflection are rarely and often poorly discussed with relatives and that no or incomplete guidance is offered. No review of the literature is available to date, although it could be of value to improve the quality of the daily practice.

OBJECTIVES

The objective was to review and synthesize the main concepts and approaches, theories and practices of ethical reflection support of the relatives or surrogates of potential post-mortem organ donors.

RESEARCH DESIGN

A narrative review was performed in the medical, psychological and ethical fields using PubMed, PsycArticles and Web of Science databases (1980-2020).

RESULTS

Out of 150 papers, 25 were finally retained. Four themes were drawn: the moral status of the potential post-mortem organ donor, the principlistic approach with its limits and critics, the narrative approach and the transcendental approach.

DISCUSSION

This review suggests an extension of psychological support towards ethical reflection support. The process of helping relatives in their ethical exploration of post-mortem organ donation is psychologically and morally characterized. The need for specialized professionals educated and experienced both in clinical psychology and in health ethics to carry out this task is discussed.

PRACTICAL IMPACT

This review could contribute to optimize the quality of the ethical reflection support by initiating an evolution from an empirical, partial and individual-dependent support to a more systematized, professionalized and exhaustive support.

A scoping review of the perceptions of death in the context of organ donation and transplantation

BACKGROUND

Socio-cultural perceptions surrounding death have profoundly changed since the 1950s with development of modern intensive care and progress in solid organ transplantation. Despite broad support for organ transplantation, many fundamental concepts and practices including brain death, organ donation after circulatory death, and some antemortem interventions to prepare for transplantation continue to be challenged. Attitudes toward the ethical issues surrounding death and organ donation may influence support for and participation in organ donation but differences between and among diverse populations have not been studied.

OBJECTIVES

In order to clarify attitudes toward brain death, organ donation after circulatory death and antemortem interventions in the context of organ donation, we conducted a scoping review of international English-language quantitative surveys in various populations.

STUDY APPRAISAL

A search of literature up to October 2020 was performed, using multiple databases. After screening, 45 studies were found to meet pre-specified inclusion criteria.

RESULTS

32 studies examined attitudes to brain death, predominantly in healthcare professionals. In most, around 75% of respondents accepted brain death as equivalent to death of the person. Less common perspectives included equating death with irreversible coma and willingness to undertake organ donation even if it caused death. 14 studies examined attitudes to organ donation following circulatory death. Around half of respondents in most studies accepted that death could be confidently diagnosed after only 5 min of cardiorespiratory arrest. The predominant reason was lack of confidence in doctors or diagnostic procedures. Only 6 studies examined attitudes towards antemortem interventions in prospective organ donors. Most respondents supported minimally invasive procedures and only where specific consent was obtained.

CONCLUSIONS

Our review suggests a considerable proportion of people, including healthcare professionals, have doubts about the medical and ethical validity of modern determinations of death. The prognosis of brain injury was a more common concern in the context of organ donation decision-making than certainty of death.

Ethical considerations in the use of pre-mortem interventions to support deceased organ donation: A scoping review

AIM

Pre-mortem interventions (PMIs) are performed on patients before the determination of death in order to preserve or enhance the possibility of organ donation. These interventions can be ethically controversial, and we thus undertook a scoping review of the ethical issues surrounding diverse PMIs.

METHODS

Using modified scoping review methods, we executed a search strategy created by an information specialist. Screening and iterative coding of each article was done by two researchers using qualitative thematic analysis, and narrative summaries of coded themes were presented.

RESULTS

We identified and screened 5365 references and coded 196 peer-reviewed publications. The most frequently cited issues were related to possible harms to the patient who is a potential donor, and legitimacy of consent. The most controversial issue was that PMIs may place patients at risk for physical harm, yet benefit is accrued mainly to recipients. Some authors argued that lack of direct medical benefit to the still living patient precluded valid consent from surrogate decision makers (SDMs), while many stated that some medical risk could be approved by SDMs if it aligns with non-medical benefits valued by the patient.

CONCLUSION

PMIs require consensus that benefit includes concepts beyond medical benefit to the patient who is a potential donor. Informed consent must be confirmed for each PMI and not assumed to be part of general consent for donation. Risk must be proportionate to the potential benefit and newly proposed interventions should be reviewed carefully for medical efficacy and potential risks.

Obtaining tissues and organs: empowering actions of nurses in the light of ecosystem thinking

OBJECTIVES

to analyze, in the light of ecosystem thinking, the actions of nurses that stimulate the potential to increase the rates of organ and tissue donation.

METHODS

descriptive, exploratory, mixed method study, of the embedded type, with simultaneous realization and emphasis on the quantitative approach, including 125 nurses from the Intra-hospital Commission for Donation of Organs and Tissues for Transplants in the Southern Region of Brazil. Data were collected using an online survey questionnaire. Quantitative data were analyzed using the Statistical Package for the Social Sciences software; and qualitative, Bardin content analysis.

RESULTS

the identified actions refer to the reception of the family, exclusive dedication and remunerated valorization of the nurses of the commission, media and dissemination campaigns for society in general and educational actions for the training of professionals.

CONCLUSIONS

the results of the actions encourage the possibility of increasing the rates of organ and tissue donation for transplantation.

Role of intensive care nurses on guiding patients' families/relatives to organ donation

Objective:

The aim was to determine the role of intensive care nurses on guiding the families/relatives of brain-death patients to organ donation.

Methods:

This research is a descriptive study. While the population of the study consisted of 1710 nurses working in the intensive care units of public, private and university hospitals in the city of Istanbul, the sample consisted of 353 intensive care nurses selected with stratified random sampling method from the probability sampling methods from this population. The data were collected by using “Data Collection Form”.

Results:

It was determined that 74.5% of the intensive care nurses carefully listened the family/relatives of the patient with possible brain death or suffering from brain death and supported them to express their emotion and thoughts clearly; when the family/relatives of the patients hospitalised in the intensive care unit wanted to get information about organ donation, 20.7% of the nurses made the preliminary explanation themselves and then guided the patient to an organ transplant coordinator for detailed information and 3.1% of the nurses generally gave this information themselves.

Conclusions:

It was determined that the knowledge of the intensive care nurses about brain death and organ donation was partially adequate and the function of guiding the families/relatives of brain-death patients to organ donation was mostly done by the physician.

Summary of Spanish recommendations on intensive care to facilitate organ donation

With the aim of consolidating recommendations about the practice of initiating or continuing intensive care to facilitate organ donation (ICOD), an ad hoc working group was established, comprising 10 intensivists designated by the Spanish Society of Intensive Care and Coronary Units (SEMICYUC) and the Spanish National Transplant Organization (ONT). Consensus was reached in all recommendations through a deliberative process. After a public consultation, the final recommendations were institutionally adopted by SEMICYUC, ONT, and the Transplant Committee of the National Health-Care System. This article reports on the resulting recommendations on ICOD for patients with a devastating brain injury for whom the decision has been made not to apply any medical or surgical treatment with a curative purpose on the grounds of futility. Emphasis is made on the systematic referral of these patients to donor coordinators, the proper assessment of the likelihood of brain death and medical suitability, and on transparency in communication with the patient's family. The legal and ethical aspects of ICOD are addressed. ICOD is considered a legitimate practice that offers more patients the opportunity of donating their organs upon their death and helps to increase the availability of organs for transplantation.

[Critical care management of the potential organ donor : Current recommendation for adults]

The shortage of donor organs has not improved in recent years. To increase the number and success of transplantation it is crucial to optimize the processes of early identification of potential organ donors and structured critical care management. The therapy starts long before brain death is diagnosed. Structured in-house organ donor management protocols ensure a highly qualified critical care that has a direct impact on the transplantation outcome. The therapy is based on the established standards. The main focus is on differentiated catecholamine and volume therapy. Vasopressin, in combination with norepinephrine, is effective for both treating vasoplegia and electrolyte disturbances. Despite poor evidence, steroids are useful for stabilizing hemodynamics and treating the consequences of neuroendocrine dysfunction. Overall, prospective studies are required to give general recommendations for critical care.

[Deaths that save lives: the complexities of medical care for patients with suspected brain death]

The objective of this study was to understand how physicians at the largest emergency department in a large Brazilian city orient care for critical patients with suspected brain death and who are potential organ donors. This ethnographic study was conducted in an emergency care hospital, a reference in traumatology in Latin America, located in downtown Belo Horizonte, Minas Gerais State. The institution took pioneering steps in Brazil with a specific sector where patients with suspected brain death are referred. The fieldwork was performed over the course of nine months, based on targeted observations and interviews with 43 on-duty staff physicians (25 men and 18 women), from 28 and 69 years of age. Data analysis followed the "signs, meanings, and actions" model. The ethnography revealed the process of medical care for patients with suspected brain death, including: intensive care, adherence to protocol, and communicating the patient's status to the family. In the latter case, the dialogue reveals the controversies in the concept of brain death, the sociocultural context, and the emergency care context. It became clear that this process of medical care extrapolates merely normative issues, entering into a complex web of elements, especially the professional's role as mediator of a myriad of interwoven elements and tensions. Between confirmation of the brain death and communicating the situation to the family, ambivalent perceptions emerge, both for the physicians and the family members. The study evidenced how the tenuous definition of what constitutes life and death touches on all of the medical act, with direct implications on care for patients/potential donors and their families.

What do people agree to when stating willingness to donate? On the medical interventions enabling organ donation after death

Purpose of the study

The purpose of this study is to explore donor relatives’ experiences of the medical interventions enabling organ donation, as well as to examine the donor relatives’ attitudes towards donating their own organs, and whether or not their experiences have influenced their own inclination to donate.

Methods

The experiences of donor relatives were explored via in-depth interviews. The interviews covered every step from the deceased family member being struck by a severe bleeding in the brain till after the organ recovery, including the medical interventions enabling organ donation. The interviews were analysed through qualitative and quantitative content analysis.

Results

Brain death and organ donation proved to be hard to understand for many donor relatives. The prolonged interventions provided after death in order to enable organ donation misled some relatives to believe that their family member still was alive. In general, the understanding for what treatment aimed at saving the family member and what interventions aimed at maintaining organ viability was low. However, most donor relatives were either inspired to, or reinforced in their willingness to, donate their own organs after having experienced the loss of a family member who donated organs.

Conclusions

There is a need for greater transparency regarding the whole chain of events during the donation process. Yet, having experienced the donation process closely did not discourage the donor relatives from donating their own organs–but rather inspired a willingness to donate. This indicates an acceptance of the medical procedures necessary in order to enable organ donation after death.

Perspectives toward brain death diagnosis and management of the potential organ donor

BACKGROUND

Organ donation and transplantation represent one of the most important scientific advances over the last decades. Due to the complexity of these procedures and related ethical-legal aspects, however, there are a lot of doubts and uncertainty about the brain death diagnosis and the maintenance of potential organ donor.

AIM

To identify and discuss the different meanings and experiences of registered nurses and physicians from an adult intensive care unit in relation to the diagnosis of brain death and the maintenance of potential organ donors for transplantation purposes.

STUDY DESIGN

Participants were registered nurses and physicians from an adult intensive care unit at a University Hospital from Brazil. Data were collected through semi-structured interviews and analyzed using content analysis.

ETHICAL CONSIDERATIONS

This study was approved by the University of São Paulo at Ribeirão Preto College of Nursing Research Ethics Committee.

RESULTS

Two main categories emerged from the analysis: (1) brain death diagnosis and its implications and (2) maintenance of the potential organ donor and its repercussion in the donation-transplantation process. Six subcategories were also identified: (1.1) understanding the brain death diagnosis as a tool to aid decision-making; (1.2) diagnosis as guarantee of rights; (1.3) difficulties encountered to establish the diagnosis; (1.4) clinical criteria adopted in Brazil and related ethical-legal aspects; (2.1) specificities of care to the brain dead person and outcomes; and (2.2) nurse's duties toward the brain dead person.

CONCLUSION

Although the brain death diagnosis is scientifically and legally defined in Brazil and the maintenance of the potential organ donor for transplantation purposes has been addressed during the last years, there are still some doubts about the subject, as its understanding varies according to the personal beliefs, culture, and educational background of individuals, including those who work in this scenario.

[Therapy escalation for the potential organ donor : Are all intensive care measures also ethically justifiable?]

The gap between the number of organs needed and the number available has dramatically increased in Germany in the last decade-for intensivists and transplantation specialists, it is challenging to cover the demand responsibly. It is therefore increasingly important to identify potential organ donors in order to realize organ donation. An escalation of intensive care measures is often required, which raises critical ethical questions. In Germany, organ donation is only allowed after brain death with prior informed consent from the deceased or his/her relatives. Determining the willingness of the potential organ donor and adapting the subsequent intensive care to it requires experience and empathy. Therapy escalation for the realization of organ donation is not opposed to the basic ethical principles of medicine, but remains an individual decision. A time limitation of this last intensive therapy phase to achieve optimal conditions for transplantation should be discussed with the relatives and adapted to the medical requirements. This article would like to highlight ethical questions that are relevant in the context of therapy escalation of potential organ donors and, thus, support the decision-making process.

An assessment of advance relatives approach for brain death organ donation

BACKGROUND:

Advance announcement of forthcoming brain death has developed to enable intensivists and organ procurement organisation coordinators to more appropriately, and separately from each other, explain to relatives brain death and the subsequent post-mortem organ donation opportunity.

RESEARCH AIM:

The aim was to assess how potentially involved healthcare professionals perceived ethical issues surrounding the strategy of advance approach.

RESEARCH DESIGN:

A multi-centre opinion survey using an anonymous self-administered questionnaire was conducted in the six-member hospitals of the publicly funded East of France regional organ and tissue procurement network called 'Prélor'.

PARTICIPANTS:

The study population comprised 460 physicians and nurses in the Neurosurgical, Surgical and Medical Intensive Care Units, the Stroke Units and the Emergency Departments.

ETHICAL CONSIDERATIONS:

The project was approved by the board of the Lorraine University Diploma in Medical Ethics and the Prélor Network administrators.

MAIN FINDINGS:

A slight majority of 53.5% of respondents had previously participated in an advance relatives approach: 83% of the physicians and 42% of the nurses. A majority of healthcare professionals (68%) think that the main justification for advance relatives approach is the comprehensive care of the dying patient and the research of his or her most likely opinion (74%). The misunderstanding of the related issues by relatives is an obstacle for 47% of healthcare professionals and 51% think that the answer given by the relatives regarding the most likely opinion of the person regarding post-mortem organ donation really corresponds to the person opinion in only 50% of the cases or less.

CONCLUSION:

Time given by advance approach should be employed to help and enable relatives to authentically bear the values and interests of the potential donor in the post-mortem organ donation discussion. Nurses' attendance of advance relatives approach seems necessary to enable them to optimally support the families facing death and post-mortem organ donation issues.

Organ Donation and Elective Ventilation: A Necessary Strategy

Organ transplantation is the sole treatment to improve or save the life of patients with final-stage organ failure. The shortage of available organs for transplantation constitutes a universal problem, estimating that 10% of patients on waiting lists die. Brain death is an undesirable result; nevertheless, it has beneficial side-effects since it is the most frequent source of organs for transplantation. However, this phenomenon is relatively uncommon and has a limited potential. One of the options that focuses on increasing organ donation is to admit patients with catastrophic brain injuries (with a high probability of brain death and nontreatable) to the Intensive Care Unit, with the only purpose of donation. To perform elective nontherapeutic ventilation (ENTV), a patient's anticipated willingness to donate organs and/or explicit acceptance by his/her relatives is required. This process should focus exclusively on those patients with catastrophic brain injuries and imminent risk of death which, due to its acute damage, are not considered treatable. This article defends ENTV as an effective strategy to improve donation rate, analyzing its ethical and legal basis.

Intensive care medicine and organ donation: exploring the last frontiers?

The main, universal problem for transplantation is organ scarcity. The gap between offer and demand grows wider every year and causes many patients in waiting list to die. In Spain, 90% of transplants are done with organs taken from patients deceased in brain death but this has a limited potential. In order to diminish organ shortage, alternative strategies such as donations from living donors, expanded criteria donors or donation after circulatory death, have been developed. Nevertheless, these types of donors also have their limitations and so are not able to satisfy current organ demand. It is necessary to reduce family denial and to raise donation in brain death thus generalizing, among other strategies, non-therapeutic elective ventilation. As intensive care doctors, cornerstone to the national donation programme, we must consolidate our commitment with society and organ transplantation. We must contribute with the values proper to our specialization and try to reach self-sufficiency by rising organ obtainment.
