Relational Self 關係性自我

The enhanced patient autonomy approach requires the inclusion of family members in the decision making process. (Surbone,

2006)

Patient autonomy = complex concept referring to both one’s capacity to choose and to one’s ability to implement one’s choices

Advanced Directives from a

Catholic Perspective

Francisco de Vitoria

 ordinary vs. extraordinary means 普通 vs. 特殊的手段

Medical advances now gave doctors much more options to cure and prolong life, and even prolong the dying process.

Pope Pius XII in 1957.

Ordinary vs extraordinary means

Ordinary (proportionate

相稱

) means are those basic care and treatments which doctors are obligated to provide and which under normal circumstances, patients should not refuse—run of the mill medical treatment, hygiene, antibiotics, etc.

Extraordinary (disproportionate 不相稱 ) means are those medical measures that can cause undue burden on the patients and the family, and therefore patients are not obliged to undergo these (experimental) treatments, or if they have been started could ask for their withdrawal.

Ordinary vs extraordinary means

There are objective and subjective elements that the patients and doctors must weigh the risks and benefits in each case.

Objective elements such as the difficulties, pain risk, cost and success rates, etc.

Subjective elements include fear, anxiety, physical or psychological suffering, shame, the desire to live on, the time to settle affairs, etc.

Preferred term is proportionality, since some ordinary means can become disproportionate in very ill patients, and some extraordinary means can be proportionate to patient needs when the risk and benefits are weighed.

Therapeutic obstinacy and

Euthanasia

Two extremes to be avoided.

Therapeutic obstinacy 治療頑固 : When all available treatments have been tried and patient is dying, doctors should accept this rather than employing all technology to prolong the dying process, thus causing more suffering and does not respect the dignity of the person.

(Unrealistic expectations from patients, family and doctors: Medicine or doctors seen as saviors, failure). Pius XII: extraordinary means can be withheld or withdrawn.

Therapeutic obstinacy and

Euthanasia

CCC 2278 Discontinuing medical procedures that are burdensome, dangerous, extraordinary, or disproportionate to the expected outcome can be legitimate; it is the refusal of “over-zealous” treatment.

“過分熱心 ” 治療 Here one does not will to cause death; one's inability to impede it is merely accepted.

The decisions should be made by the patient if he is competent and able or, if not, by those legally entitled to act for the patient, whose reasonable will and legitimate interests must always be respected.

Therapeutic obstinacy and

Euthanasia

Euthanasia: to end someone’s suffering by intentionally ending his or her life.

“By euthanasia is understood an action or an omission which of itself or by intention causes death, in order that all suffering may in this way be eliminated.”

(Declaration on Euthanasia 1980,

EV, CCC)

Level of intention, includes omission if the intention is there to provoke death. Could be voluntary or non-voluntary.

 安樂死:結束一個

人的痛苦,故意結

束她的生命。

 意向的 層次

 包括不行動故意造

成死亡

 可能是自願或不自

願的。

PVS and ANH

植物人 , 人工營養與水分

Water and nutrition are basic needs, not therapy.

Withdrawal with the intention to cause death, since PVS patients could live on indefinitely. That is, cause of death is starvation and dehydration.

Recent report form NEJM—some of them can have thought processes.

Historical Background on

Advanced directives

Quinlan Case: Natural Death Act 1979

Karen Ann Quinlan, PVS and on ventilator. Parents petitioned for withdrawal of respirator, but doctors refused. Court decided that ventilator is an extraordinary means, and can be withdrawn, citing Pius

XII.

Natural Death Act: There is a right to express one’s will regarding life sustaining treatments, and the right to withdraw or withhold them. In the case of mental incapacity, these rights can be expressed by either

Advanced Directives (written document) or durable power of attorney (proxy) by naming someone who could make the decision on behalf of the patient.

Historical Background on

Advanced directives

Cruzan Case: Patient Self-determination Act 1991

Nancy Cruzan also PVS, on artificial nutrition and hydration (PEG). Family wanted removal of tube feeding against doctor’s judgment. They were able to demonstrate retrospectively that this was the patient’s desire.

Patient Self-determination Act requires all health care institutions to advise all patients admitted to their facilities the availability of advanced directives.

Terri Schiavo

Context of the Living Will movement

Fear of technology: hooked up to machine and living an undignified existence

Euthanasia movement in the 1980s found it difficult to change the laws to permit euthanasia.

More emphasis on who decides rather than what is best for the patient.

Individualism: Self-determination often becomes the only criteria

Critiques

Difficulties in explaining to patients the medical conditions, and they could be subject to manipulation, undue fears and ideological pressures. Not truly informed consent.

Difficulty in foreseeing all possible future situations which can be complex. When circumstances change, people can change their minds (eg. Charles Kao)

Damaging relationships between doctors and patients: Doctors just execute the patient decision as a robot

Tyranny of Autonomy: Respect of the person includes looking for what is best for the patient.

Not all decisions are wise and good. One can choose the wrong thing. “No man is an island”—recent shift of emphasis that decision making is best when made in a wider “relational” context including family, friends, and co-religionists. Familism in Asia.

Legal frameworks

Legally binding (USA, Australia, UK,

Holland, Belgium) or just consultative and indicative (Italy, Germany, Austria)

Existence of Catholic versions of “Advanced

Directives” that respect the Catholic teaching (e.g. NCBC). In general, resistance to its use because of these problems.

Introduction of the Concept of

Advanced Directives in Hong Kong

Terminal illness / irreversible coma / PVS, are very different conditions.

Different principles apply here—for eg., any treatment in truly irreversible coma would be wrong, even ANH. Whereas in the case of PVS, withdrawal of ANH would be euthanasia.

Euthanasia defined as “direct intentional killing of a patient as a part of the medical care being offered.” Omission can also be a means of intentional killing.

Artificial vs. natural rather than proportionality the criteria. That is, artificial means are always inappropriate or burdensome… Definition of life-sustaining treatment includes ANH. (Catholic hospitals should not cooperate with this)

Family or relatives seen as enemies to patient self-determination.

Elimination of proxy as an option. This is absurd in the Asian context, especially in view of the recent shift of opinion coming from the Western experience.

Options only to withdraw or withhold treatments, no mention of desire to continue treatments under these conditions. Doubt: cost saving measures?
