Attitudes regarding organ donation from non-heart-beating donors

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.

Survey of public attitudes towards imminent death donation in the United States

Imminent death donation (IDD) is described as living organ donation prior to a planned withdrawal of life-sustaining care in an imminently dying patient. Although IDD was ethically justified by United Network for Organ Sharing, the concept remains controversial due to presumed lack of public support. The aim of this study was to evaluate the public's attitudes towards IDD. A cross-sectional survey was conducted of US adults age >18 years (n = 2644). The survey included a case scenario of a patient with a devastating brain injury. Responses were assessed on a 5-point Likert scale. Results showed that 68% - 74% of participants agreed or strongly agreed with IDD when posed as a general question and in relation to the case scenario. Participants were concerned about "recovery after a devastating brain injury" (34%), and that "doctors would not try as hard to save a patient's life" (33%). Only 9% of participants would be less likely to trust the organ donation process. In conclusion, our study demonstrates strong public support for IDD in the case of a patient with a devastating brain injury. Notably, participants were not largely concerned with losing trust in the organ donation process. These results justify policy change towards imminent death donation.

Decision-making in end of life care. Are we really playing together in the same team?

BACKGROUND

Limitation of life-sustaining treatment is increasingly common in critical care units, and controlled donation after circulatory death is starting to be included as an option within patient care plans. Lack of knowledge and misunderstandings can place a barrier between healthcare professionals.

OBJECTIVE

To determine the perceptions, knowledge and attitudes of physicians and nurses working in intensive care units regarding Limitation of life-sustaining treatment and controlled donation after circulatory death.

DESIGN, SETTINGS AND PARTICIPANTS

Cross-sectional study carried out in 13 Spanish hospitals by means of an ad hoc questionnaire.

METHODS

Contingency tables, Pearson's chi-squared test, Student's t-test and the Mann-Whitney u-test were used to carry out descriptive, bivariate and multivariate statistical analyses of responses.

RESULTS

Although Limitation of life-sustaining treatment is a widespread practice, the survey revealed that nurses feel excluded from the development of protocols and the decision-making process, whilst the perception of physicians is that they have greater knowledge of the topic, and decisions are reached in consensus.

CONCLUSIONS

Multi-disciplinary training programmes can help critical healthcare providers to work together with greater coordination, thus benefitting patients and their next of kin by providing excellent end-of-life care.

Impact of training on intensive care providers' attitudes and knowledge regarding limitation of life-support treatment and organ donation after circulatory death

The limitation of life-sustaining treatment is common practice in critical care units, and organ donation after circulatory death has come to be included as an option within this care plan. Lack of knowledge and misunderstandings can raise barriers between health-care providers (e.g., confusion about professional roles, lack of collaboration, doubts about the legality of the process, and not respecting patients' wishes in the decision-making process). The aim of the present study was to determine the knowledge and attitudes of intensive care physicians and nurses before and after a multidisciplinary online training program. A cross-sectional study was performed, and comparisons between the two groups were made using a χ² -test for categorical data and unpaired t-test or Mann-Whitney rank sum test for continuous data according to its distribution. Training benefited both professional categories, helping nurses to be more open-minded and willing to collaborate, while physicians became more aware of nurses' presence and the need to collaborate with them.

Are Organ Donation Attitudes and Beliefs, Empathy, and Life Orientation Related to Donor Registration Status?

Context

The severe organ donor shortage necessitates additional research on variables that may distinguish those who register to be organ donors and those who do not. Such research has important implications for the development of educational interventions.

Objective

To examine whether registered organ donors differ significantly from nondonors on measures of organ donation beliefs and attitudes, empathy, and life orientation.

Design and Setting

Prospective participants were approached about the study while visiting a local branch of the Department of Motor Vehicles. Once consent was obtained, participants completed several questionnaires.

Participants

Two hundred fifty community dwellers who visited the Department of Motor Vehicles office in Alachua County, Fla.

Main Outcome Measures

Organ donor registration status, beliefs about organ donation, attitudes toward organ donation, empathy, and life orientation (ie, optimism).

Results

Registered organ donors reported more positive beliefs toward organ donation than did nonregistered participants or participants who were undecided about their registration status. Registered organ donors also reported more positive organ donation attitudes and more optimism than did nonregistered participants.

Controlled Donation After Circulatory Determination of Death

Controlled donation after circulatory determination of death (cDCDD) concerns donation after withdrawal of life-sustaining therapy (W-LST). We examine the ethical issues raised by W-LST in the cDCDD context in the light of a review of cDCDD protocols and the ethical literature. Our analysis confirms that W-LST procedures vary considerably among cDCDD centers and that despite existing recommendations, the conflict of interest in the W-LST decision and process might be difficult to avoid, the process of W-LST might interfere with usual end-of-life care, and there is a risk of hastening death. In order to ensure that the practice of W-LST meets already well-established ethical recommendations, we suggest that W-LST should be managed in the ICU by an ICU physician who has been part of the W-LST decision. Recommending extubation for W-LST, when this is not necessarily the preferred procedure, is inconsistent with the recommendation to follow usual W-LST protocol. As the risk of conflicts of interest in the decision of W-LST and in the process of W-LST exists, this should be acknowledged and disclosed. Finally, when cDCDD programs interfere with W-LST and end-of-life care, this should be transparently disclosed to the family, and specific informed consent is necessary.

Attitudes toward Death Criteria and Organ Donation among Healthcare Personnel and the General Public

Objective

To examine attitudes toward death criteria and their relation to attitudes and behaviors regarding organ donation.

Data Sources

This article reviews empirical studies on the attitudes of healthcare personnel and the general public regarding death criteria and organ donation.

Study Selection and Data Extraction

The review was restricted to studies that had as a primary focus attitudes toward 1 or more of the following 3 specific criteria for determining death: (1) brain death, the irreversible loss of all functions of the entire brain; (2) higher brain death, the loss of cerebral cortex function alone; and (3) the circulatory-respiratory criteria commonly used in donation after cardiac death.

Data Synthesis

Studies consistently show that the general public and some medical personnel are inadequately familiar with the legal and medical status of brain death; attitudes toward the dead donor rule are strong predictors of willingness to donate organs using controversial criteria; concerns about donation after cardiac death surround the withdrawal of life support more than the actual death criteria used; and concerns about death criteria correlate with less favorable attitudes toward organ donation.

Conclusions

Both general and ethical education may serve to guide policy and facilitate family member requests and informed consent dialogues. Furthermore, helping families to understand and accept not only medical and legal criteria for determining death, but also ethical criteria for withdrawing life support may help them be more comfortable with their decisions.

Neonatal and Pediatric Organ Donation: Ethical Perspectives and Implications for Policy

The lifesaving processes of organ donation and transplantation in neonatology and pediatrics carry important ethical considerations. The medical community must balance the principles of autonomy, non-maleficence, beneficence, and justice to ensure the best interest of the potential donor and to provide equitable benefit to society. Accordingly, the US Organ Procurement and Transplantation Network (OPTN) has established procedures for the ethical allocation of organs depending on several donor-specific and recipient-specific factors. To maximize the availability of transplantable organs and opportunities for dying patients and families to donate, the US government has mandated that hospitals refer potential donors in a timely manner. Expedient investigation and diagnosis of brain death where applicable are also crucial, especially in neonates. Empowering trained individuals from organ procurement organizations to discuss organ donation with families has also increased rates of consent. Other efforts to increase organ supply include recovery from donors who die by circulatory criteria (DCDD) in addition to donation after brain death (DBD), and from neonates born with immediately lethal conditions such as anencephaly. Ethical considerations in DCDD compared to DBD include a potential conflict of interest between the dying patient and others who may benefit from the organs, and the precision of the declaration of death of the donor. Most clinicians and ethicists believe in the appropriateness of the Dead Donor Rule, which states that vital organs should only be recovered from people who have died. The medical community can maximize the interests of organ donors and recipients by observing the Dead Donor Rule and acknowledging the ethical considerations in organ donation.

Non-therapeutic intensive care for organ donation

Background and Purpose:

Providing non-therapeutic intensive care for some patients in hopeless condition after cerebrovascular stroke in order to protect their organs for possible post-mortem organ donation after brain death is an effective but ethically tricky strategy to increase organ grafting. Finding out the feelings and opinion of the involved healthcare professionals and assessing the training needs before implementing such a strategy is critical to avoid backlash even in a presumed consent system.

Participants and methods:

A single-centre opinion survey of healthcare professionals was conducted in 2013 in the potentially involved wards of a French University Hospital: the Neurosurgical, Surgical and Medical Intensive Care Units, the Stroke Unit and the Emergency Department. A questionnaire with multiple-choice questions and one open-ended question was made available in the different wards between February and May 2013.

Ethical considerations:

The project was approved by the board of the Lorraine University Diploma in Medical Ethics.

Results:

Of a total of 340 healthcare professionals, 51% filled the form. Only 21.8% received a specific education on brain death, and only 18% on potential donor’s family approach and support. Most healthcare professionals (93%) think that non-therapeutic intensive care is the continuity of patient’s care. But more than 75% of respondents think that the advance patient’s consent and the consent of the family must be obtained despite the presumed consent rule regarding post-mortem organ donation in France.

Conclusion:

The acceptance by healthcare professionals of non-therapeutic intensive care for brain death organ donation seems fairly good, despite a suboptimal education regarding brain death, non-therapeutic intensive care and families’ support. But they ask to require previously expressed patient’s consent and family’s approval. So, it seems that non-therapeutic intensive care should only remain an ethically sound mean of empowerment of organ donors and their families to make post-mortem donation happen as a full respect of individual autonomy.

Views of pediatric intensive care physicians on the ethics of organ donation after cardiac death

OBJECTIVE

Donation after cardiac death has been endorsed by professional organizations, including the American Academy of Pediatrics as a means of increasing the supply of transplantable organs. However, ethical concerns have been raised about donation after cardiac death, especially in children. This study explores the views of pediatric intensive care physicians on the ethics of pediatric donation after cardiac death.

DESIGN

Internet survey.

SUBJECTS

Physician members of the American Academy of Pediatrics Section of Critical Care.

INTERVENTIONS

Physicians were emailed an anonymous survey consisting of four demographic items and 16 items designed to assess their views on the ethics of pediatric donation after cardiac death. Responses to ethics items were rated on a 5-point scale ranging from strongly disagree to strongly agree. Physicians were also given the opportunity to provide free-text comments regarding their views.

MEASUREMENTS AND MAIN RESULTS

Of the 598 eligible physicians, 264 (44.1%) responded to the survey. Of these, 193 (73.4%) were practicing in a transplant center and 160 (60.6%) participated in at least one donation after cardiac death procedure at the time of survey completion. Two hundred twenty (83.4%) agreed or strongly agreed that regarding donation after cardiac death, parents should be able to make decisions based on the best interests of their child. Two hundred twenty-two (84.1%) agreed or strongly agreed that it is not acceptable to harvest organs from a child before the declaration of death, consistent with the Dead Donor Rule. However, only 155 (59.1%) agreed or strongly agreed that the time of death in donation after cardiac death can be conclusively determined. Twenty-nine (11.0%) agreed or strongly agreed that the pediatric donation after cardiac death donor may feel pain or suffering during the harvest procedure.

CONCLUSIONS

Most pediatric intensive care physicians agree that the Dead Donor Rule should be applied for donation after cardiac death and that donation after cardiac death can be consistent with the best interest standard. However, concerns about the ability to determine time of death for the purpose of organ donation and the possibility of increasing donor pain and suffering exist.

Donation after cardiac death: community views about 'decent' intervals

Donation after cardiac death (DCD) offers an alternative pathway to donation for some donors. Successful recovery of organs for transplantation following DCD requires that organ recovery surgery commence as soon as possible after death has occurred. This limits the amount of time that family and friends can spend with the donor prior to surgery. The aim of this study was to identify community views about the timing of organ recovery in DCD. Data were collected from two sources in South Australia: 32 members of the public participated in four focus groups, and 2693 adults participated in a representative population survey. Respondents were asked their views about a decent interval to wait after death prior to organ recovery surgery. Focus group participants identified a tension between preserving organ viability and allowing families time with the deceased. Of the survey respondents, 45.2% selected a timeframe compatible with potentially viable donations; 34.1% selected a timeframe incompatible with viable donations; and 20.8% gave an indeterminate answer. These findings provide information about public perceptions of DCD, can be used to inform educational campaigns about DCD and serve as a baseline for evaluating such campaigns, and identify a number of areas for further investigation.

Are Front Line Health Professionals Responsible for the Organ Crisis?

The process and techniques of organ transplantation have improved significantly; however, there remains a supply-demand mismatch that appears to grow wider as years go by. In this literature review, databases covering published studies from 1990 to 2006 were searched for studies focused on medical doctors' and/or registered nurses' attitudes towards human-to-human organ donation and/or transplantation. The results indicate that healthcare professionals do play a significant part in the procurement of organs for transplantation and may be partly responsible for the lack of transplantable organs available. However, the review further illustrates their complex role within the healthcare system, and suggests that responsibility for organ procurement may be best placed within the domain of specialist personnel.

Survey of pediatricians' opinions on donation after cardiac death: are the donors dead?

OBJECTIVE

There has been debate in the ethics literature as to whether the donation-after-cardiac-death donor is dead after 5 minutes of absent circulation. We set out to determine whether pediatricians consider the donation-after-cardiac-death donor as dead.

METHODS

A survey was mailed to all 147 pediatricians who are affiliated with the university teaching children's hospital. The survey had 4 pediatric patient scenarios in which a decision was made to donate organs after 5 minutes of absent circulation. Background information described the organ shortage, and the debate about the term "irreversibility" applied to death in donation after cardiac death. Descriptive statistics were used, with responses between groups compared by using the chi(2) statistic.

RESULTS

The response rate was 54% (80 of 147). In each scenario, when given a patient described as dead with absent circulation for 5 minutes, <or=60% of respondents strongly agreed/agreed that the patient is definitely dead, <or=50% responded that the patient is in the state called "dead," and <or=56% strongly agreed/agreed that the physicians are being truthful when calling the patient dead. On at least 1 of the scenarios, 38 (48%) of 147 responded uncertain, disagree, or strongly disagree that the patient is definitely dead. Although the patients in the 4 scenarios were in the identical physiologic state, with absent circulation for 5 minutes, 12 (15%) of 80 respondents did not consistently consider the patients in the state called "dead" between scenarios. Fewer than 5% of respondents answered strongly agree/agree to allow donation after cardiac death while also answering disagree/strongly disagree that the patient is definitely dead, suggesting little support to abandon the dead-donor rule.

CONCLUSIONS

Most pediatrician respondents were not confident that a donation-after-cardiac-death donor was dead. This suggests that additional debate about the concept of irreversibility applied to donation after cardiac death is needed.

(Uncontrolled) donation after cardiac determination of death: a note of caution

In this short article, we articulate a position that organ recovery from uncontrolled DCD (uDCD)--primarily patients who have suffered a cardiac arrest--is unlikely to result in a significant number of organs, and this small gain must be balanced against significant risk of unduly influencing resuscitation provider decision-making, and jeopardizing public trust in the propriety of organ donation and transplantation.

Intensive Care Unit Extubation Does Not Preclude Extrarenal Organ Recovery from Donors after Cardiac Death

BACKGROUND

We have sought to increase the utilization of both renal and extrarenal organs from donors after cardiac death (DCD), including DCD donors with ICU extubation.

METHODS

Extubation occurred in the intensive care unit (ICU; n=15) and operating room (OR; n=5). The charts of donors were reviewed for demographics, cause of death, time of asystole and cold perfusion. Recipient's charts were reviewed for graft function, length of hospitalization, serum creatinine (Cr) at discharge and last follow-up. Peak transaminases, amylase, and lipase for liver and pancreas recipients were also reviewed. Data are presented as means+/-SEM.

RESULTS

From December 2002 until December 2004, 20 DCD donors were utilized yielding 34 kidney transplants (33 recipients), five liver (1 liver-kidney), and two pancreas (SPK) transplants. Mean follow-up overall is 260 days. ICU extubation occurred in 26/33 (78.8%) kidneys, 3/5(60%) livers and 1/2 (50%) pancreata performed. Time from extubation to asystole was 15.9+/-1.9 min and overall warm ischemia time was 12.5+/-1.0 min. Serum Cr at discharge and at last follow-up for renal grafts are 4.3+/-0.5 and 1.9+/-0.3 mg/dl, respectively. Peak AST and ALT levels after OLTx were 3620+/-951 and 1955+/-266 i.u., respectively. Peak and discharge total bilirubin were 8.1+/-0.9 and 2.5+/-0.5 mg/dl. Length of hospitalization was 9.6+/-1.0 and 15.8+/-2.3 days for kidney and liver recipients, respectively. Both pancreas recipients were insulin free after transplant.

CONCLUSIONS

ICU extubation should not eliminate extrarenal organs from consideration and may be preferable to OR extubation by improving family support and eliminating OR staff concerns about their role in end-of-life care.

Executive summary from the Intraoperative Advisory Council on Donation After Cardiac Death of the United Network for Organ Sharing: practice guidelines

The number of organs recovered from asystolic donors is less than anticipated and is explained partially by negative attitudes held by health care providers. To understand the reasons for these beliefs and find solutions, the United Network for Organ Sharing under contract with the Department of Health and Human Services convened the Intraoperative Advisory Council on Donation After Cardiac Death in September, 2001. The Council found that, unlike other medical specialties, operating room health care providers were uncertain of their roles and duties in the care of donors declared dead with cardiopulmonary criteria, known as donation after cardiac death. They were reluctant to care for terminally ill patients in whom death was an expected outcome. Council members deliberated these issues, seeking solutions to repatriate operating room health care providers with the national effort to provide reliable and compassionate care to organ donors and their families. The Council requested the construction of practice guidelines, believing that the structure provided by guidelines will improve health provider confidence in donation after cardiac death and thus improve the quality of care. Physician and nonphysician health care providers from the operating room met to create the Guidelines for the United Network for Organ Sharing, which they believe will improve the quality of care of asystolic organ donors.
