ADVANCE DIRECTIVES
René Descartes
...that we could be free of an infinitude of
maladies both of body and mind, and even
also possibly of the infirmities of age, if we
had sufficient knowledge of their causes,
and of all remedies with which nature has
provided us.
René Descrates: Discourse on Method,
Part VI.)
Four Principles of Medical Ethics
Nonmaleficence
Beneficence
Autonomy
Justice
Advance Care Planning
= process whereby a patient, in
consultation with healthcare providers,
family members, and important others,
makes decisions about his or her future
healthcare
„Every human being of adult years and
sound mind has the right to determine
what shall be done with his own body.“
(Benjamin Cardozzo´s statement, 1914)
USA
state laws allow individuals to complete
advance directives documents and to
name healthcare decision makers
federal law requires all patients admitted
to hospital to be notified of this right
most european countries have followed
suit with provisions for advance care
planning
Health Care Proxy
in association with passage of the Patient Self-
Determination Act (1990) laws has been passed
that enable individuals to designate the person
they wish to make healthcare decisions for them
once they lose decision-making capacity
in addition, laws pertaining to informed consent
have given family members the right to make
decisions on behalf of incapacitated patients
an alternative to family-based substitute decision
making is using the courts, such as assigning a
court-appointed guardian. This mechanism
exists in both USA and Canada
Decision Makers
USA
if no healthcare agent is authorized and available, the
practitioner must make a reasonable inquiry as to the
availability of other possible surrogates according to
the order of priority
legal guardian
spouse
adult child
parent
sibling
grandparent
grandchild
close friend
(Veterans Health Administration, 2003)
Decision Makers
when patients are asked who they would
want to represent them, the majority opt
for their own family members
(Singer, P.A., Viens, A.M., (eds.) (2008) The Cambridge Textbook of Bioethics. Cambridge University
Press, p.60)
Patients at increased risk for losing decisionmaking capacity
These high risk situation include:
early dementia
history of stroke
health conditions that predispose to a future stroke
(e.g. uncontrolled hypertension)
health conditions that predispose to delirium (e.g.
frailty, advanced age)
terminal illness
recurrent severe psychiatric illnesses (e.g. severe
dementia, mania, psychosis)
families with conflicts
social isolation (e.g. no family members or close
friends)
Health Care Proxy
= a substitute decision maker
the criteria on which the decision should
be based are:
the specific wishes previously expressed by
the patient
if specific wishes are not known, the patient´s
known values and beliefs
if neither specific wishes or values and beliefs
are known, the patient´s best interests
Problems
advance care planning has not been as
successful as proponents would wish
some patients change their views as time
passes
others request life-prolonging interventions
that subsequently prove to be unrealistic
substitute decision makers are not always
sure that a patient´s situation is equivalent to
that described in an advance directive
Substituted judgement and best interests
Substituted judgements
liwing will, advanced directives
without an advance directive, a proxy may then refer to
the patient´s values, both implicit and explicit,
regarding worldview (including religious beliefs),
lifestyle, and health care.
Best interests
in many cases, a proxy may not have any information a
bout a paataient´s values (infant, young children,
mentally disabled adults)
health is preferable to ilness, and life is preferable to
death
A twenty-eight-year-old man decided to terminate chronic renal dialysis because of
his restricted lifestyle and the burdens on his family. He had diabetes, was legally
blind and could not walk because of progressive neuropathy. His wife and
physician agreed to provide medication to relieve his pain and further agreed not to
put him back on dialysis even if he requested this action under the influence of
pain or other bodily changes. (Increased amounts of urea in the blood which restlt
from kidney failure, can sometimes lead to altered mental states, for example).
While dying in the hospital, the patient awoke complaining of pain and asked to be
put back on dialysis. The patient´s wife and physician decided to act on the
patient´s earlier request not to intervence, and he died four hours later.

Patient Adopted by the 34th World Medical Assembly, Lisbon, Portugal,1981
The unconscious patient
If the patient is unconscious or otherwise unable to
express his/her will, informed consent must be
obtained whenever possible, from a legally entitled
representative.
If a legally entitled representative is not available, but a
medical intervention is urgently needed, consent of the
patient may be presumed, unless it is obvious and
beyond any doubt on the basis of the patient's previous
firm expression or conviction that he/she would refuse
consent to the intervention in that situation.
However, physicians should always try to save the life
of a patient unconscious due to a suicide attempt.
Persistent Vegetative State (PVS)
= a clinical condition of unawareness of
self and environment in which the patient
breathes spontaneously, has a stable
circulation, and shows cycles of eye
closure and opening which may simulate
sleep and waking
the vegetative state has to have endured
for at least one month in order for it to be
considered persistent The Multi-Society Task Force on PVS,

Donald Dax Cowart
In 1973, Donald Cowart was critically injured in a
propane gas explosion, that caused severe
burns over sixty-five percent of his body.
For more than a year, he objected to the painful
treatments that he was receiving. Cowart was
physically incapable of ending his own life, since
his hands had been severely damaged in the
accident, but he made repeated verbal requests
that he be allowed to die, or that someone help
him end his own life.
Donald Dax Cowart
Despite his protestation, his doctors and
his mother continued to provide treatment,
including a number of paonful skin graft
surgeries.
Cowart survived the ordeal and is still
alive today, but insists that hed should
have been allowed to die.

Eluana Englaro
1972 - 2009
in a persistent vegetative
state since being injured
in a car crash in 1992.
In July 2008, a court in
Milan ruled that doctors
had proved Ms Englaro's
coma was irreversible.
It also accepted that,
before the accident, she
had expressed a
preference for dying over
being kept alive artificially.
Eluana Englaro
1972 - 2009
Eluana Englaro, the comatose woman at the
centre of a euthanasia debate that divided Italy
and sparked a constitutional crisis, died on Feb
9 2009 at the age of 38, four days after doctors
began to remove her life support.
She had been in a vegetative state for 17
years after a car accident. Ms Englaro’s father
had been fighting for a decade for a dignified
end to his daughter’s life in accordance with
what he and her friends have testified were her
own wishes. At his request, doctors at a clinic
in Udine stopped feeding.
Eluana Englaro
1972 - 2009
Italy's Prime Minister Silvio
Berlusconi drafted a decree to
prevent doctors from letting her
die, but President Giorgio
Napolitano refused to sign it.
Italy does not allow euthanasia.
Patients have a right to refuse
treatment, but they are not
allowed to give advance
directions on the treatment they
wish to receive if they become
unconscious.
Trace of Thought Is Found in
‘Vegetative’ Patient
Dobrovolník či pacient má myslet na pohybovou aktivitu (hraní tenisu), když
chce říci „ano“ a má se uvolnit nebo myslet na prostorovou aktivitu (procházení
se po ulicích), chce-li říci „ne“
Trace of Thought Is Found in
‘Vegetative’ Patient
A two-way channel to an immobilized, severely
brain-injured person also opens up a world of
ethical challenges.
“If you ask a patient whether he or she wants to
live or die, and the answer is die, would you be
convinced that that answer was sufficient?” said
Dr. Joseph J. Fins, chief of the medical ethics
division at Weill Cornell Medical College in New
York. “We don’t know that.
Their answer might be ‘Yes, but’ — and we
haven’t given them the opportunity to say the
‘but.’

Futile Treatment
quantitative futility
a treatment is capable of producing a result,
but extremely unlikely to do so
recovery is "impossible" or "virtually
impossible"
qualitative futility
the problem lies not in the low probabilities,
but when there are questions about the value
of the end result ("lacking in purpose")
"Good"
how much longer life is an unqualified good
for an individual?
how much more life is good for us as
individuals, other things being equal?
the simple answer is that no limit should be set.
life is good, death is bad
some, of course, eschew any desire for
longer life
they profess still more modest claim:
not adding years to life, but life to years
no increased life span, but only increased health
The problem of boredom and tedium
if the life span were increased - say by
twenty years - would the pleasures of life
increase proportionately?
would professional tennis players really enjoy
playing 25 percent more games of tennis?
would the Don Juans of our world feel better
for having seduced 1 250 women rather than
1000?
The problem of boredom and tedium
Leon Kass
To know and to feel that one goes around
only once, and that the deadline is not out
of sight, is for many people the necessary
slur to the pursuit of somenting
worthwhile. To number our days is the
condition for making them count and for
treasuring and appreciating all that life
brings
The problem of boredom and tedium

Homer´s immortals, for all their eternal
beauty and youthfulness, live shallow and
rather frivolous lives, their passions only
transiently engaged, in first this and then
that.
they live as spectators of the mortals,
who by comparison have depth,
aspiration, genuine feeling, and hence a
real centre to their lives.

It is probably no accident that it is a
generation whose intelligentsia proclaim
the meaninglessness of life that embarks
on its indefinite prologation and that seeks
to cure the emptiness of life by extending
it.
