One or two types of death? Attitudes of health professionals towards brain death and donation after circulatory death in three countries.

This study examined health professionals' (HPs) experience, beliefs and attitudes towards brain death (BD) and two types of donation after circulatory death (DCD)--controlled and uncontrolled DCD. Five hundred and eighty-seven HPs likely to be involved in the process of organ procurement were interviewed in 14 hospitals with transplant programs in France, Spain and the US. Three potential donation scenarios--BD, uncontrolled DCD and controlled DCD--were presented to study subjects during individual face-to-face interviews. Our study has two main findings: (1) In the context of organ procurement, HPs believe that BD is a more reliable standard for determining death than circulatory death, and (2) While the vast majority of HPs consider it morally acceptable to retrieve organs from brain-dead donors, retrieving organs from DCD patients is much more controversial. We offer the following possible explanations. DCD introduces new conditions that deviate from standard medical practice, allow procurement of organs when donors' loss of circulatory function could be reversed, and raises questions about "death" as a unified concept. Our results suggest that, for many HPs, these concerns seem related in part to the fact that a rigorous brain examination is neither clinically performed nor legally required in DCD. Their discomfort could also come from a belief that irreversible loss of circulatory function has not been adequately demonstrated. If DCD protocols are to achieve their full potential for increasing organ supply, the sources of HPs' discomfort must be further identified and addressed.

"Allow natural death" is not equivalent to " do not resuscitate": a response.

Venneman and colleagues argue that "do not resuscitate" (DNR) is problematic and should be replaced by "allow natural death" (AND). Their argument is flawed. First, while end-of-life discussions should be as positive as possible, they cannot and should not sidestep painful but necessary confrontations with morality. Second, while DNR can indeed be nonspecific and confusing, AND merely replaces one problematic term with another. Finally, the study's results are not generalisable to the populations of physicians and working nurses and certainly do not support the authors' claim that there is a movement to replace DNR with AND.

Should individuals choose their definition of death?

Alireza Bagheri supports a policy on organ procurement where individuals could choose their own definition of death between two or more socially accepted alternatives. First, we claim that such a policy, without any criterion to distinguish accepted from acceptable definitions, easily leads to the slippery slope that Bagheri tries to avoid. Second, we suggest that a public discussion about the circumstances under which the dead donor rule could be violated is more productive of social trust than constantly moving the line between life and death.

Transfer of the hematopoietic stem cell transplant patient to the intensive care unit: does it really matter?

We critically reviewed published English language literature and concluded that from 1998 onward the survival of hematopoietic stem cell transplant (SCT) patients who experienced intensive care unit (ICU) transfer has improved. The factors associated with increased mortality during ICU stay included increased patient age, allogeneic transplant, intubation/mechanical ventilation, multiorgan system failure (MOSF), presumed/documented infection, graft-versus-host disease, and higher APACHE and O-PRISM score at ICU transfer. This encouraging outcome trend reflects evolving advances such as use of recombinant hematopoietic growth factors, use of mobilized blood cells rather than marrow, protective strategies for acute lung injury and early goal-directed therapy for sepsis syndrome. Patient selection bias (which patients were transferred and which were not sent to an ICU) also plays a role in ICU survival rates. New strategies to improve upon SCT patient outcome include use of a scoring system to predict mortality, better therapies for MOSF and integration of ICU components and multispecialist involvement earlier in the clinical course to prevent severe complications such as respiratory failure. SCT recipients comprise a heterogeneous group; to further advance this field, prospective multicenter trials involving larger populations from many centers are needed to reduce the biases of retrospective and single-center reports.

Philosophical debates about the definition of death: who cares?

Since the Harvard Committee's bold and highly successful attempt to redefine death in 1968 (Harvard Ad Hoc committee, 1968), multiple controversies have arisen. Stimulated by several factors, including the inherent conceptual weakness of the Harvard Committee's proposal, accumulated clinical experience, and the incessant push to expand the pool of potential organ donors, the lively debate about the definition of death has, for the most part, been confined to a relatively small group of academics who have created a large body of literature of which this issue of the Journal of Medicine and Philosophy is an example. Law and public policy, however, have remained essentially unaffected. This paper will briefly review the multiple controversies about defining death in an attempt to explain why they have and will remain unresolved in the academic community and have even less chance of being understood and resolved by politicians, legislators, and the general public. Considering this, we will end by suggesting the probable course of public policy and clinical practice in the decades ahead.

Health care ethics consultation: nature, goals, and competencies. A position paper from the Society for Health and Human Values-Society for Bioethics Consultation Task Force on Standards for Bioethics Consultation.

Patients, families, and health care providers have a right to expect that ethics consultants can deal competently with the complex issues that they are asked to address. The Society for Health and Human Values-Society for Bioethics Consultation Task Force on Standards for Bioethics Consultation explored core competencies and related issues in ethics consultation. This position paper summarizes the content of the resulting Task Force Report, which included nine general conclusions: 1) U.S. societal context makes "ethics facilitation" an appropriate approach to ethics consultation; 2) ethics facilitation requires certain core competencies; 3) core competencies can be acquired in various ways; 4) individual consultants, teams, or committees should have the core competencies for ethics consultation; 5) consult services should have policies that address access, patient notification, documentation, and case review; 6) abuse of power and conflicts of interest must be avoided; 7) ethics consultation must have institutional support; 8) evaluation of process, outcomes, and competencies is needed; and 9) certification of individuals and accreditation of programs are rejected.

Bureaucratizing suicide.

Although helpful in many ways, the Guidelines for Assessing Mental Capacity and Impaired Judgment fall short in 3 areas. First, the term capacity is poorly defined and explicated. Second, the inevitable role of the evaluator's own values is given short shrift. Finally, the Guidelines rely too heavily on lists and formal test without guidance about what is most important. This failure threatens to further burden dying patients with unwanted and unnecessary bureaucratic intrusion.

An annotated bibliography for ethics training in consultation-liaison psychiatry.

The expanding field of bioethics has created a need in psychiatry for rapid access to the complex bioethics literature. This is especially true in consultation-liaison work. An annotated bibliography was created by a task force of the Academy of Psychosomatic Medicine charged with exploring how psychiatrists function on bioethics committees. The bibliography is organized into headings that reflect how bioethical problems came to the attention of psychiatrists. Introductory references allow the reader an overview of the history of bioethics and a selection of useful textbooks. References are provided explaining how ethical principles are used. References are also organized by areas of medical work frequently visited by consultation-liaison psychiatrists.

Increased risk of death in patients with do-not-resuscitate orders.

BACKGROUND: Whereas studies have shown higher mortality rates in patients with do-not-resuscitate (DNR) orders, most have not accounted for confounding factors related to the use of DNR orders and/or factors related to the risk of death. OBJECTIVE: To determine the relationship between the use of DNR orders and in-hospital mortality, adjusting for severity of illness and other covariates. DESIGN: Retrospective cohort study. PATIENTS: There were 13,337 consecutive stroke admissions to 30 hospitals in 1991 to 1994. MEASURES: To decrease selection bias, propensity scores reflecting the likelihood of a DNR order were developed. Scores were based on nine demographic and clinical variables independently related to use of DNR orders. The odds of death in patients with DNR orders were then determined using logistic regression, adjustment for propensity scores, severity of illness, and other factors. RESULTS: DNR orders were used in 22% (n = 2,898) of patients. In analyses examining DNR orders written at any time during hospitalization, unadjusted in-hospital mortality rates were higher in patients with DNR orders than in patients without orders (40% vs. 2%, P<0.001); the adjusted odds of death was 33.9 (95% CI, 27.4-42.0). The adjusted odds of death remained higher in analyses that only considered orders written during the first 2 days (OR 3.7; 95% CI, 3.2-4.4) or the first day (OR 2.4; 95% CI, 2.0-2.9). In stratified analyses, adjusted odds of death tended to be higher in patients with lower propensity scores. CONCLUSION: The risk of death was substantially higher in patients with DNR orders after adjusting for propensity scores and other covariates. Whereas the increased risk may reflect patient preferences for less intensive care or unmeasured prognostic factors, the current findings highlight the need for more direct evaluations of the quality and appropriateness of care of patients with DNR orders.

Prosecutors and end-of-life decision making.

OBJECTIVE: To examine personal beliefs and professional behavior of state criminal prosecutors toward end-of-life decisions. DESIGN: Mail survey. SETTING: District attorney offices nationwide. PARTICIPANTS: All prosecuting attorneys who are members of the National District Attorneys Association. A total of 2844 surveys were mailed with 2 follow-up mailings at 6-week intervals; 761 surveys were returned for a response rate of 26.8%. The majority of respondents were white men, Protestant, and served in rural areas. INTERVENTIONS: None. MAIN OUTCOME MEASURES: On the basis of 4 case scenarios, (1) professional behavior as determined by respondents' willingness to prosecute and what criminal charges they would seek; and (2) personal beliefs as determined by whether prosecutors believed the physicians' actions were morally wrong and whether they would want the same action taken if they were in the patient's condition. RESULTS: Most respondents would not seek prosecution in 3 of the 4 cases. In the fourth case, involving physician-assisted suicide, only about one third of the respondents said that they definitely would prosecute. Those who would prosecute would most often seek a charge of criminal homicide. A majority of respondents believed that the physicians' actions were morally correct in each of the 4 cases and would want the same action taken if they were in the patient's position. There was a strong correlation between personal beliefs and professional behaviors. CONCLUSIONS: A large majority of responding prosecutors were unwilling to prosecute physicians in cases that clearly fall within currently accepted legal and professional boundaries. In the case of physician-assisted suicide, results reflected a surprisingly large professional unwillingness to prosecute and an even greater personal acceptance of physician-assisted suicide.

Variation in the use of do-not-resuscitate orders in patients with stroke.

OBJECTIVES: To identify sociodemographic and clinical characteristics associated with the use of do-not-resuscitate (DNR) orders in hospitalized patients with stroke. To examine whether the use of DNR orders varies across hospitals. METHODS: This observational cohort study used data collected for 13337 consecutive eligible patients with a primary diagnosis of stroke. These patients were discharged in 1991 through 1994 from 30 hospitals in a large metropolitan area. Study data were abstracted from patients' hospital records using standard forms. Admission severity of illness was measured using a validated multivariable model. Sociodemographic and clinical factors independently associated with the use of DNR orders were identified using stepwise logistic regression. RESULTS: Do-not-resuscitate orders were written for 2898 patients (22%). Patient characteristics independently (P < .01) associated with increased use of DNR orders included increasing age (odds ratio [OR], 1.06 per year); admission from a skilled nursing facility (OR, 2.44) or through the emergency department (OR, 1.49); cancer (OR, 2.73), intracerebral hemorrhage (OR, 2.12), coma (OR, 7.47), or lethargy or stupor on admission neurological assessment (OR, 3.38); and increasing admission severity (OR; 1.29 per decile). In contrast, African American race was associated with lower use of DNR orders (OR, 0.54). Although substantial variation in the use of DNR orders was observed across hospitals, with rates ranging from 12% to 32%, adjusting for the above patient characteristics eliminated much of this variation, including differences between major teaching and other hospitals and between hospitals with and without religious affiliations. CONCLUSIONS: In our community-based analysis of patients with stroke, the use of DNR orders was common and was strongly related to several patient characteristics. These factors explained much of the variation across hospitals. While our analysis did not account for differences in patient preferences for treatment, the differences we observed in the use of DNR orders across sociodemographic groups are suggestive of variations in care and may have important implications for the cost and quality of hospital care.

Consultation-liaison psychiatry and clinical ethics. Historical parallels and diversions.

As clinical ethicists increasingly populate hospital settings, a definition of their roles and responsibilities vis à vis those of consultation-liaison (C-L) psychiatrists remains a matter of both interest and uncertainty. Both fields share certain evolutionary and ideological features, yet until very recently, psychiatry has ignored medical ethics, leaving the field to other medical specialties. This estrangement can be explained by psychiatry's traditional suspicion and devaluation of moral philosophy and its more recent wish to be identified more with biomedicine than with the "softer" social sciences and humanities. C-L psychiatry has both a lot to offer and a lot to learn from clinical ethics.

Dialysis patient attitudes toward financial incentives for kidney donation.

Offering financial incentives to families of brain-dead individuals has been proposed as a way to increase the supply of organs for transplantation. However, such incentives may lead to weakening of altruism and exploitation of poor families. We investigated dialysis patient attitudes toward the potential benefits and problems of incentives. Using a structured questionnaire, we interviewed 60 randomly selected patients at three chronic hemodialysis units. Subjects were asked to make an explicit trade-off between maintaining altruism versus increasing the supply of kidneys. They were also asked to make a trade-off between protecting poor families versus increasing the supply of kidneys. In addition, we asked subjects how they thought incentives would affect donation by different types of families. We found that 37% of all subjects placed more emphasis on maintaining altruism, 42% placed more emphasis on increasing the supply of kidneys, and 22% placed an equal emphasis on maintaining altruism and on increasing the supply of kidneys. Similarly, 35% of all subjects placed more emphasis on protecting poor families, 33% placed more emphasis on increasing the supply of kidneys, and 32% placed an equal emphasis on protecting poor families and on increasing the supply of kidneys. Subjects thought financial incentives would greatly increase donation by poor families while having little impact on rich families. In conclusion, even though dialysis patients are likely to benefit from increasing the supply of kidneys, many of them want to maintain altruism and protect poor families even if that means fewer kidneys. These concerns should be addressed in proposals to modify the transplant system.

Medical futility.

Recent discussions about futility have been useful in elucidating health professionals' responsibility to communicate, to establish trust, and to collaborate with patients and families about end-of-life decisions. They have highlighted the often impersonal and fragmented care that patients receive in today's large medical centers. Futility also has been a stalking horse for the much more important and problematic issue of rationing. The latter must be discussed on its own merits, however painful that may be.
