Acceptance in Theory but not Practice – Chinese Medical Providers’ Perception of Brain Death

Healthcare Professionals’ Understandings of the Definition and Determination of Death: A Scoping Review

Background.

During the 1950s, advances in critical care, and organ transplantation altered the relationship between organ failure and death. There has since been a shift away from traditional cardiocirculatory based to brain-based criteria of death, with resulting academic controversy, despite the practice being largely accepted worldwide. Our objective is to develop a comprehensive description of the current understandings of healthcare professionals regarding the meaning, definition, and determination of death.

Methods.

Online databases were used to identify papers published from 2003 to 2020. Additional sources were searched for conference proceedings and theses. Two reviewers screened papers using predefined inclusion and exclusion criteria. Complementary searches and review of reference lists complemented the final study selection. A data extraction instrument was developed to iteratively chart the results of the review. A qualitative approach was conducted to thematically analyze the data.

Results.

Seven thousand four hundred twenty-eight references were identified. In total, 75 papers met the inclusion criteria. Fourteen additional papers were added from complementary searches. Most were narratives (35%), quantitative investigations (21%), and reviews (18%). Identified themes included: (1) the historical evolution of brain death (BD), (2) persistent controversies about BD and death determination, (3) wide variability in healthcare professionals’ knowledge and attitudes, (4) critical need for BD determination revision.

Conclusions.

We concluded that although BD is widely accepted, there exists variation in healthcare providers’ understanding of its conceptual basis. Death determination remains a divisive issue among scholars. This review identified a need for increased opportunities for formal training on BD among healthcare providers.

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.

Muslim American physicians' views on brain death: Findings from a national survey

Background

Biotechnology has introduced a new physiological state, "brain death," that continues to attract controversy and confusion. While variability in diagnostic criteria for, and physician practices regarding, "brain death" has been studied, few studies examine physicians' normative views on the significance of "brain death" and how religiosity implicates these views.

Objective

The objective is to assess how Muslim physicians' views on death, and how their religiosity and acculturation, associate with their perceptions of "brain death."

Methods

A randomized national sample of 626 American Muslim physicians completed a mailed questionnaire assessing sociodemographic characteristics, religiosity, and views about death. Measures of religious practice and acculturation were analyzed as predictors of physician views at the bivariate and multivariable levels. In conducting the multivariate analysis, P-values less than 0.05 were deemed statistically significant.

Results

Two-hundred and fifty-five respondents completed the survey (41% response rate). Most participants agreed that death is the irreversible cessation of cardiac and respiratory function (90%), while half agreed or disagreed with other definitions of death, such as loss of personhood or the equivalence of cardiopulmonary and neurological criteria for death. Physicians who scored higher on the religious practice scale had significantly lower odds of agreeing with the statement; "brain death" signifies the departure of the soul from the body [odds ratio (OR) = 0.57, 95% confidence interval (CI): 0.33-0.98]. Those who were born in the US, or immigrated to the US as a child, had greater odds of viewing death as the irreversible loss of personhood and consciousness [OR = 3.52, 95% CI: 1.62-7.63].

Conclusion

Physician characteristics such as religiosity and acculturation appear to influence their views on what constitutes death and how it should be diagnosed. In our sample of Muslim physicians, there appears to be significant reservation toward equating neurological and cardiopulmonary criteria to determine death and disquiet regarding the meaning of "brain death" in general.

Cultural sensitivity in brain death determination: a necessity in end-of-life decisions in Japan

Background

In an increasingly globalized world, legal protocols related to health care that are both effective and culturally sensitive are paramount in providing excellent quality of care as well as protection for physicians tasked with decision making. Here, we analyze the current medicolegal status of brain death diagnosis with regard to end-of-life care in Japan, China, and South Korea from the perspectives of front-line health care workers.

Main body

Japan has legally wrestled with the concept of brain death for decades. An inability to declare brain death without consent from family coupled with cultural expectations of family involvement in medical care is mirrored in other Confucian-based cultures (China and South Korea) and may complicate care for patients from these countries when traveling or working overseas. Within Japan, China, and South Korea, medicolegal shortcomings in the diagnosis of brain death (and organ donation) act as a great source of stress for physicians and expose them to potential public and legal scorn. Here, we detail the medicolegal status of brain death diagnosis within Japan and compare it to China and South Korea to find common ground and elucidate the impact of legal ambiguity on health care workers.

Conclusion

The Confucian cultural foundation of multiple Asian countries raises common issues of family involvement with diagnosis and cultural considerations that must be met. Leveraging public education systems may increase awareness of brain death issues and lead to evolving laws that clarify such end-of-life issues while protecting physicians from sociocultural backlash.
