The Definition of Death
-
Two types of cases at the center of controversy
-
"brain-dead" or "whole brain-dead" patients
-
entire brain has irreversibly ceased functioning
-
so they are irreversibly unconscious
-
but cardiopulmonary function is maintained successfully by a respirator
and allied technology
-
"persistent vegetative state" (PVS) patients
-
brainstem function remains sufficient to sustain respiration and heartbeat
-
but due to irreversible damage to "the higher brain" or cerebral cortex
-
consciousness and cognition are irretrievably lost
-
Issues
-
Are patients in each group alive or dead?
-
What is the morally appropriate treatment for them?
-
Dueling standard
-
Traditional standard: permanent absence of respiration and and
heartbeat
-
according to this standard brain-dead patients are alive
-
as long as cardiopulmonary function can be artificially maintained
-
Whole-Brain: permanent nonfunctioning of the whole brain (proposed
in an influential Harvard Medical School ad hoc committee report in 1978)
-
according to this standard "whole brain-dead" patients are dead
-
even if cardiopulmonary function is being artificially maintained
-
Bio-Ethical Importance of the Difference: Examples
-
Concerning organ transplantation
-
if the patient is already dead, then taking vital organs for transplantation
(given appropriate consent) is morally unproblematic
-
if the patient is not already dead then taking the organs will be the cause
of the patients death, which is morally problematic
-
you're killing someone
-
to benefit someone else
-
Removal from respirator
-
if the patient is alive then we are allowing the patient to die by removing
life-sustaining treatment
-
if the patient is dead then the treatment isn't truly life-sustaining and
we don't allow the patient to die by removing it
-
Change of Consensus: Whole-Brain has become the Accepted Standard
-
1981 President's Commission's 1981 report Defining Death recommends
the adoption by all states of the Uniform Determination of Death Act
-
according to the Uniform Determination of Death Act an individual is dead
who has sustained either
-
"irreversible cessation of circulatory and respiratory function" or
-
"irreversible cessation of all functions of the entire brain, including
the brain stem"
-
Live Issues concerning the status of PVS individuals: Discussion in text
-
Robert M. Veatch
-
proposes a "higher brain-death" standard according to which a patient
is death who has sustained irreversible cessation of higher brain function
as most rational.
-
this should be the default position
-
nevertheless, each individual should be allowed to choose the definition
of death
-
most responsive to their personal or religious convictions
-
to be applied in their own case
-
through the exercise of a conscience clause which would allow them
to stipulate either
-
the traditional standard
-
or the whole-brain
-
Culver & Gert
-
urge a crucial distinction between
-
the death of the organism
-
the organism ceasing to be a person
-
traditional definition (following John Locke) a (moral) person has
-
consciousness: self awareness, including memory and foresight
-
cognition: intellectual, conceptual, or reasoning abilities
-
crucially
-
there could be nonhuman persons: perhaps dolphins, or ETs, or AIs
-
there can be and are human nonpersons
-
very young infants are not persons (yet)
-
the profoundly retarded and demented and not full persons
-
PVS individuals might be said to be profoundly nonpersons.
-
against the "higher brain-death" standard
-
should continue to think of inducing cardiac arrest as killing the patient
-
removing a PVS patients organs for transplantation likewise should continue
to be viewed as killing them
-
such direct killing is morally dubious (compare active euthanasia)
-
nevertheless it's morally permissible in the treatment of PVS patients
to "allow them to die"
-
by discontinuing all care (compare passive euthanasia)
-
even "ordinary and routine care" such as
Competent Adults and the Refusal of Life-Sustaining Treatment
-
Distinction: 3 Types of Cases (admittedly rough & ready)
-
where a patient, by accepting life-sustaining treatment, would return to
a state of health
-
rough edge: How assuredly?
-
refusal of treatment uncommon but "dramatic": e.g.,
-
Jehovah's Witness who refuses a live-saving blood transfusion
-
Christian Scientist who refuses a live-saving appendectomy
-
Ruth Macklin argues -- on grounds of autonomy -- that such refusals should
be allowed
-
where a patient, by accepting treatment, would prolong a severely compromised
-
rough edge: how severely?
-
refusal of treatment becoming increasingly more common
-
example: a severe arthritis sufferer who refuses treatment for her pneumonia
-
successful treatment will fully restore her to her previous highly impaired
& painful condition
-
which is nevertheless not a terminal condition
-
so it's not just "prolonging the dying process"
-
controversy
-
favoring condoning such refusal: considerations of autonomy
-
reservations about condoning such refusal: based on reluctance to recognize
"quality of life" factors as morally relevant
-
terminal illness: where a patient, by accepting treatment, would merely
prolong the dying process (
-
rough edges: How long? Ain't life terminal?
-
such refusal has a strong foundation in morality & law and is very
common: where treatment would merely "prolong the dying process" mentally
competent patients are generally recognized to have moral and legal rights
to refuse such treatment
-
example: a terminal cancer sufferer whose death can be postponed for a
time by "aggressive treatment"
-
Kantian -- autonomy based -- reasons to recognize such a right
-
Utility-based reasons: may be highly questionable in such cases whether
treatment is in the patient's best interest
-
if it will lead to a more miserable and prolonged process of dying
-
where less aggressive treatment -- or nontreatment -- might lead to a better
death
-
with less suffering
-
and more awareness, communicative capacity, etc.
-
Controversial Distinction: Types of Life-Sustaining Treatment
-
"extraordinary means": mechanical respiration, kidney dialysis, surgery,
antibiotics
-
"ordinary means": nutrition and hydration, even if artificially delivered
(e.g., by IV)
-
controversy
-
some argue against allowing refusal of nutrition and hydration due to the
symbolic connection of food and water with care and concern
-
others (including the AMA Council on Ethical and Judicial Affairs) argue
that nutrition and hydration are like any other treatment
-
they may fail to provide sufficient benefit to warrant continuance
-
and competent patients should be allowed to make this decision for themselves
-
Controversial Distinction
-
withholding life-sustaining treatment, i.e., never beginning it
-
withdrawing life-sustaining treatment that is already underway
-
controversy
-
many physicians are more comfortable withholding than withdrawing
-
AMA Council on Ethical and Judicial Affairs insists there is no ethically
significant difference
Resuscitation Decisions, DNR Orders, and Judgments of Futility
-
President's Commission for the Study of Ethical Problems in Medicine and
Biomedical and Behavioral Research
-
patient self-determination should be the single most important factor in
resuscitation decisions
-
physician's assessment of benefit to the patient is also relevant
-
proposes guidelines for balancing these factors in variety of cases
-
of competent patients (summarized in Table 1 on p. 339)
-
of incompetent patients (summarized in Table 2 on p. 340)
-
Tomlinson & Brody: Rationales for DNR orders
-
rationales involving quality of life judgments
-
since such judgments must ultimately made by the patient (or their family
if the patient is incompetent)
-
it's wrong for physician to write a DNR order in such cases without the
patient (or their surrogate's) permission
-
the rationale that resuscitation would almost certainly be futile
-
such judgments fall within the purview of the physicians expertise
-
and are most appropriately left to the physician alone
-
physicians are not obligated to provide treatments they consider
futile even if patients (or their surrogates) desire them
-
Mark Wicclair: judgments of "futility" are not purely objective but always
involve an evaluative component
Advance Directives and Treatment Decisions for Incompetent Adults
-
Advance Directives
-
rationale
-
terminal illness, treatments, and the dying process may impair the decision-making
capacities of the terminally ill patient
-
advance directives provide a reliable way for the patient to make their
wishes know to the physician and their families while their decision-making
capacities are still unimpaired
-
two types of directives
-
instructional directives wherein
-
a person specifies instructions about care desired
-
in case their decision-making capacities become impaired
-
when it deals with decisions regarding withholding of life-sustaining treatment,
such instructional directives are commonly known as "living wills"
-
proxy directives wherein
-
a person specifies a surrogate to make health-care decisions for them
-
in the event their decision-making capacities become impaired
-
the legal mechanism for executing a proxy directive is called a "durable
power of attorney" for health care
-
not the same as financial "durable power of attorney"
-
my wife's families case
-
reasons for choosing a proxy directive over or in addition to an instructional
directive
-
written directives can be ambiguous
-
foreseeing all the contingencies that might arise is next to impossible
-
Surrogate Decision makers obligations
-
where instructional directives exist, follow them
-
where no such directives exist or are unclear apply the substituted
judgment standard
-
make the decision the patient would have made
-
given their values and preferences
-
if they had been able to choose
-
where the substitute judgment standard yields no clear guidance apply the
best-interests standard
-
make the decision that a rational person would choose
-
in the patient's circumstances
-
Difficulties with Living Wills and other Instructional Directives
-
The Patient Self-Determination Act passed by Congress in October of 1990
requires all health-care institutions receiving federal funds to inform
their patients of their rights to formulate advance directives.
-
Worries about the force, construction, and implementation of such directives
-
commonly "living will" provisions only become active upon a diagnosis of
"terminal illness"
-
excludes PVS patients
-
excludes extreme dementia patients (e.g., advanced Alzheimer's sufferers)
-
problem: it might be my wish not to linger on in a PVS but that
wish would not be accommodated under the provisions of such a living will.
-
other directives speak of "reasonable expectation of regaining a meaningful
quality of life"
-
but what's reasonable?
-
and what quality of life counts as "meaningful"
-
Issue: Is refusal to follow the provisions of a patient's instructional
directive ever justified?
-
might be good reason to think the patient would not have wanted a certain
provision to be followed -- e.g. no mechanical ventilation -- if they had
anticipated the actual circumstances that have arisen.
-
"past wishes vs. present interest problems"
-
example
-
someone who has stipulated that no life-sustaining measures are to be performed
if they become severely demented
-
but they have become severely but "pleasantly demented"
-
their life seems enjoyable to them as it is
-
even such as it is
-
upshot: life-sustaining treatment may be in their present best interests
though incompatible with their past wishes
-
Joanne Lynn: "Why I Don't Have a Living Will": It's not for everyone.
-
two groups of patients unsympathetic to providing advance directives
-
those who are uneasy about the very prospect of making choices that may
impact the length of their lives
-
those who would simply prefer to entrust the decision-making to family
or friends should the need arise
-
nevertheless there are "four good uses for advance directives"
-
cases where a patient would be well-served by executing a durable power
of attorney of health care
-
to document unusual or very specific preferences
-
to alleviate patient and family anxieties
-
as a focal point for organizing discussion of the patient's priorities
and preferences.
