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

Rest in Peace or in Pieces: Post-Mortem Care Options in U.S. Advance Directives

Advance Directives (ADs) have traditionally focused on documenting patients' end-of-life (EOL) care preferences. Recently, discussions surrounding post-mortem care as an additional aspect of EOL care planning have gained attention. This study examined ADs across all 50 states and the District of Columbia (referred to as "entities"), assessing their inclusion of two post-mortem categories: funeral planning and anatomical gifts. Results revealed that 29% of entities offered options from both categories, 43% provided options from only one of the categories, and 27% lacked options from either category. Unexpectedly, only one entity (2%) provided all post-mortem options from both categories. These findings suggest a lack of consistency in the availability of post-mortem options across ADs. By emphasizing the importance of comprehensive EOL care planning, this study provides valuable insights into the necessity for AD standardization, particularly regarding post-mortem preferences for patients who choose to express them.

Barriers to conversations about deceased organ donation among adults living in the UK: a systematic review with narrative synthesis

OBJECTIVES

To explore the barriers to conversations about deceased organ donation among adults living in the UK.

DESIGN

Systematic review with narrative synthesis.

DATA SOURCES

PubMed, MEDline via OVID, APA PsycInfo via EBSCO, Web of Science via Clarivate and Scopus via Elsevier, covering studies that were published between January 2006 and December 2023. Searches were conducted on 1 December 2023 and completed on 2 February 2024.

ELIGIBILITY CRITERIA

Studies published between January 2006 and December 2023, focusing on barriers to organ donation conversations among adults in the UK. Both qualitative and quantitative studies were included, emphasising cultural and generational factors. Non-English studies and those unrelated to the UK were excluded.

DATA EXTRACTION AND SYNTHESIS

Screening and data extraction were conducted by two independent reviewers using a standardised tool. Quality assessment was performed using Joanna Briggs Institute checklists, evaluating study bias. A narrative synthesis approach was used to integrate findings from heterogeneous studies.

RESULTS

11 studies (6 qualitative, 5 quantitative) with a total of 4991 participants were included. Four main thematic barriers emerged: (1) jinx factor-cultural beliefs associating discussion of death with bad luck; (2) generational impact-younger people were more open but cautious of upsetting parents; (3) ethnic disparities in conversations-varied challenges across diverse backgrounds and (4) cues to action-media and personal experiences prompted conversations. Facilitators included culturally tailored communication and community engagement.

CONCLUSION

Conversations about death and organ donation are often brief and hindered by cultural taboos surrounding death, generational differences in attitudes and the influence of family dynamics. Further research is needed to understand communication patterns better and to tailor interventions that encourage open discussions about organ donation across different ethnic groups.

Developing and Expanding Deceased Organ Donation to Its Maximum Therapeutic Potential: An Actionable Global Challenge From the 2023 Santander Summit

On November 9 and 10, 2023, the Organización Nacional de Trasplantes (ONT), under the Spanish Presidency of the Council of the European Union, convened in Santander a Global Summit entitled "Towards Global Convergence in Transplantation: Sufficiency, Transparency and Oversight." This article summarizes two distinct but related challenges elaborated at the Santander Summit by Working Group 2 that must be overcome if we are to develop and expand deceased donation worldwide and achieve the goal of self-sufficiency in organ donation and transplantation. Challenge 1: the need for a unified concept of death based on the permanent cessation of brain function. Working group 2 proposed that challenge 1 requires the global community to work toward a uniform, worldwide definition of human death, conceptually unifying circulatory and neurological criteria of death around the cessation of brain function and accepting that permanent cessation of brain function is a valid criterion to determine death. Challenge 2: reducing disparities in deceased donation and increasing organ utilization through donation after the circulatory determination of death (DCDD). Working group 2 proposed that challenge 2 requires the global community to work toward increasing organ utilization through DCDD, expanding DCDD through in situ normothermic regional perfusion, and expanding DCDD through ex situ machine organ perfusion technology. Recommendations for implementation are described.

Cognitive and non-cognitive factors affecting decision-making about deceased organ donation in Italy: a systematic review

INTRODUCTION

Decision-making about organ donation (OD) is influenced by interrelated cognitive and non-cognitive factors. The identification of these factors in the general population and among healthcare professionals (HCP) in Italy are key ethical and scientific requirements to inform targeted communication and policy-making interventions, and to promote decision-making processes that are truly informed.

EVIDENCE ACQUISITION

A systematic review of articles published between January 1, 1999, and January 31, 2024 was performed by searching four databases using these terms: "organ donation" AND (attitude OR opinion OR knowledge OR awareness OR intention OR beliefs OR norms OR perception) AND (Italy OR Italian). The reference sections of included articles were scrutinized for additional references.

EVIDENCE SYNTHESIS

Most respondents (lay citizens and HCPs) were in favor of OD, but many (mainly but not exclusively lay citizens) would not authorize OD in the event of death of a family member. Lack of knowledge about OD and the gap between demand and supply of organs, fear of body mutilation, doubts about the criteria for brain death diagnosis, doubts about the wishes of the deceased family member, and distrust towards medical doctors and the healthcare system were the most commonly reported reasons, confirming that cognitive and non-cognitive factors are at play.

CONCLUSIONS

The majority of the Italian population supports OD, but cognitive and non-cognitive barriers are present even among HCPs. Communication campaigns, encouraging family discussions about OD, providing better education for HCPs (including medical and nursing students), and making it easier to sign OD cards may promote informed decision-making and possibly increase consent rates.

Brain Death Knowledge and Attitudes Among Fourth-Year Medical Students at Umm Al-Qura University

Background Despite clear definitions of brain death, students and medical professionals may have varying understandings. This study investigated the knowledge and attitudes of medical students regarding brain death. Methods A cross-sectional survey was administered to 142 fourth-year medical students at Umm Al-Qura University. The survey used single-choice and Likert scale questions to assess knowledge of brain death definition, diagnosis procedures, and student attitudes. Prior to administration, the questionnaire underwent content validation by experts in medicine, ethics, and public health. Results A significant proportion of students lacked knowledge of the legal definition of brain death in Saudi Arabia (26.1%), brain death diagnostic procedures (43.7%), and prerequisites for declaring brain death (38%). While some students expressed confidence in diagnosing brain death, concerns about misdiagnosis were also present. Conclusion Fourth-year medical students in this study demonstrated significant knowledge gaps regarding brain death. Medical education programs may need to be revised to provide more comprehensive training on brain death and its implications. Additionally, public awareness campaigns could improve understanding and facilitate informed decision-making about organ donation. Further research, including multicenter studies, is warranted to confirm these findings and guide educational interventions.

Critical care specialists, the missing link in organ procurement for transplantation

The procurement process for organ donation begins with the identification of potential organ donors in emergency or critical care units (CCU), followed by their clinical evaluation, diagnostic procedures, and therapeutic interventions, mostly conducted in CCUs. It concludes with the request for organ donation and, if accepted, the retrieval of organs. Despite most interventions occurring in detection units, there has been a neglect of the strategic role played by critical care specialists (CCS) in managing and caring for brain-dead or near-brain-death patients. Questions arise: Are they willing to undertake this responsibility? Do they fully comprehend the nature of organ procurement? Are they aware of the specific interventions required to maintain possible organ donors in optimal physiological condition? Our objective is to examine the role of CCS in organ procurement and propose ways to enhance it, ultimately aiming to increase and enhance organ donation rates.

An Update on Brain Death/Death by Neurologic Criteria since the World Brain Death Project

The World Brain Death Project (WBDP) is a 2020 international consensus statement that provides historical background and recommendations on brain death/death by neurologic criteria (BD/DNC) determination. It addresses 13 topics including: (1) worldwide variance in BD/DNC, (2) the science of BD/DNC, (3) the concept of BD/DNC, (4) minimum clinical criteria for BD/DNC determination, (5) beyond minimum clinical BD/DNC determination, (6) pediatric and neonatal BD/DNC determination, (7) BD/DNC determination in patients on ECMO, (8) BD/DNC determination after treatment with targeted temperature management, (9) BD/DNC documentation, (10) qualification for and education on BD/DNC determination, (11) somatic support after BD/DNC for organ donation and other special circumstances, (12) religion and BD/DNC: managing requests to forego a BD/DNC evaluation or continue somatic support after BD/DNC, and (13) BD/DNC and the law. This review summarizes the WBDP content on each of these topics and highlights relevant work published from 2020 to 2023, including both the 192 citing publications and other publications on BD/DNC. Finally, it reviews questions for future research related to BD/DNC and emphasizes the need for national efforts to ensure the minimum standards for BD/DNC determination described in the WBDP are included in national BD/DNC guidelines and due consideration is given to the recommendations about social and legal aspects of BD/DNC determination.

The impact of clinical education on knowledge and attitudes towards brain death among Polish medical students - a cross-sectional study

BACKGROUND

Understanding brain death is essential for progress in organ transplantation; however, it remains a challenging ethical matter. In 2019, Poland revised its legislation on brain death to align with international standards. This study aimed to evaluate the knowledge and worldview concerning brain death among Polish medical students, categorised according to their stage of education.

METHODS

An online questionnaire was administered to 169 medical students from four Polish medical universities. The participants were divided into preclinical (n = 94) and clinical (n = 75) groups. The questionnaire consisted of two parts, with the first part comprising 13 questions focusing on knowledge about brain death and the process of its determination. The second part contained six questions related to the participants' worldview regarding brain death, particularly concerning organ transplantation.

RESULTS

The average score obtained by the respondents was 7.53 (± 2.35; min. 1, max. 13) in knowledge checking part of the developed questionnaire (maximal score:13). Students in the clinical stage of their education achieved significantly higher scores compared to preclinical students (mean 8.84; ± 1.89 vs mean 6.49; ± 2.15; p < 0.001). Significant correlations were found between the results of the knowledge part of the questionnaire and responses to worldview questions.

CONCLUSIONS

The stage of education influenced the knowledge of brain death among medical students, although the overall test scores were unsatisfactory. Higher test scores were associated with worldview responses indicating compliance with the current legislation in Poland and evidence-based medicine.

Decision-making About Premortem Interventions for Donation: Navigating Legal and Ethical Complexities

Premortem interventions (PMIs) for organ donation play a vital role in preserving opportunities for deceased donation or increasing the chances of successful transplantation of donor organs. Although ethical considerations relating to use of particular PMIs have been well explored, the ethical and legal aspects of decision-making about the use of PMIs have received comparatively little attention. In many countries, there is significant uncertainty regarding whether PMIs are lawful or, if they are, who can authorize them. Furthermore, emphasis on consideration of therapeutic goals in substitute decision-making frameworks may discourage consideration of donation goals. In this article, we examine the fundamental questions of who should have the authority to make decisions about the use of PMIs on behalf of a potential donor and how such decisions should be made. We draw on international examples of legal reform that have sought to clarify the legal position in relation to administering PMIs and identify potential elements of an effective regulatory model for PMIs. In doing so, we argue that reforms are needed in many countries to provide legal certainty for clinicians who are responsible for supporting decision-making about PMIs and to ensure that the goals and preferences of potential donors are accorded due consideration in the decision-making process.

Opinion of surveyed nurses on transplantation and reasons for negative public attitudes toward organ donation

Organ transplantation saves thousands of lives every year. Despite growing awareness of transplantation, the issue of obtaining organs for transplantation has been controversial for years. Hundreds of people are waiting in lines all the time for transplantation, for whom it is the only hope for a cure. One extremely important factor contributing to the low number of transplants is the low number of organ donations from deceased donors. Nurses are considered key facilitators of the organ procurement and transplantation process. Their knowledge of and attitudes toward organ donation can influence public opinion, as well as the decisions of their families to donate the organs of the deceased. The purpose of our study was to determine the opinions of surveyed nurses about transplantation and the reasons for negative public attitudes toward organ donation. The survey included 793 nurses employed in surgical wards across Poland with varying levels of job seniority. The survey was conducted between September and October 2022. The research tool was a survey questionnaire, consisting of three parts: socio-demographic data, questions assessing the respondents' knowledge of behavior about transplantation, and a non-standardized tool to measure respondents' emotional and motivational attitudes toward transplantation. Participation in the survey was anonymous and voluntary. The statistical analysis for independence of variables used the χ 2 test. On the other hand, coefficients based on the Phi and Cramer's V test, as well as Kruskal Wallis non-parametric tests for assessing differences (for more than 2 samples) were used to determine the strength of the relationship. During these analyses, in addition to standard statistical significance, the corresponding "p" values were calculated using the Monte Carlo method. According to the nurses surveyed, transplantation is a life-saving procedure. A significant proportion of the nurses (85.6%) believe that there are too few donors in Poland. According to 41.8% of the respondents, this is due to the fear of misdiagnosis of death, for 23.4% it is incompatible with their worldview or religion and 31.8% believe it is due to the belief in the inviolability of the human body after death. The survey showed that, in the nurses' opinion, the reason for objections to organ transplantation is the deficit in public's knowledge of cell, tissue and organ donation from both living and dead donors. Therefore it is extremely important to conduct educational campaigns in this regard.

The ethics of donation after circulatory death organ recovery: an overview of new considerations arising from procurement practice and policy changes

PURPOSE OF REVIEW

The aim of this study is to examine ethical issues raised by organ recovery from donors after circulatory death (DCD).

RECENT FINDINGS

Recent technological developments and policy modifications have implications for evolving ethical issues related to DCD organ procurement and donation. We identify four such changes and discuss the most significant ethical issues raised by each: the use of cardiac perfusion machines and the need to develop criteria to allow prioritization for organ preservation in joint thoracic-abdominal procurements, normothermic regional perfusion and the irreversibility criterion in the definition of death, practice variability in DCD withdrawal of care and death declarations, and equitable access to donation, and changes in organ procurement organization evaluation metrics and transplant system resource utilization.

SUMMARY

The evolution of DCD donation raises new ethical concerns that require further analysis to ensure that deceased donors, donor families and transplant recipients are treated respectfully and equitably.

A machine-learning approach to estimating public intentions to become a living kidney donor in England: Evidence from repeated cross-sectional survey data

Background

Living kidney organ donors offer a cost-effective alternative to deceased organ donation. They enable patients with life-threatening conditions to receive grafts that would otherwise not be available, thereby creating space for other patients waiting for organs and contributing to reducing overall waiting times for organs. There is an emerging consensus that an increase in living donation could contribute even more than deceased donation to reducing inequalities in organ donation between different population sub-groups in England. Increasing living donation is thus a priority for National Health Service Blood and Transplant (NHSBT) in the United Kingdom.

Methods

Using the random forest model, a machine learning (ML) approach, this study analyzed eight waves of repeated cross-sectional survey data collected from 2017 to 2021 (n = 14,278) as part of the organ donation attitudinal tracker survey commissioned by NHSBT in England to identify and help predict key factors that inform public intentions to become living donors.

Results

Overall, around 58.8% of the population would consider donating their kidney to a family member (50.5%), a friend (28%) or an unknown person (13.2%). The ML algorithm identified important factors that influence intentions to become a living kidney donor. They include, in reducing order of importance, support for organ donation, awareness of organ donation publicity campaigns, gender, age, occupation, religion, number of children in the household, and ethnic origin. Support for organ donation, awareness of public campaigns, and being younger were all positively associated with predicted propensity for living donation. The variable importance scores show that ethnic origin and religion were less important than the other variables in predicting living donor intention.

Conclusion

Factors influencing intentions to become a living donor are complex and highly individual in nature. Machine learning methods that allow for complex interactions between characteristics can be helpful in explaining these decisions. This work has identified important factors and subgroups that have higher propensity for living donation. Interventions should target both potential live donors and recipients. Research is needed to explore the extent to which these preferences are malleable to better understand what works and in which contexts to increase live organ donation.
