Nutrition and
Hydration:
Moral and Pastoral Reflections (1992)
Resource Paper
NCCB Committee for Pro-Life Activities
Introduction
Modern medical technology seems to confront us with many questions not faced
even a decade ago. Corresponding changes in medical practice have benefited
many, but have also prompted fears by some that they will be aggressively
treated against their will or denied the kind of care that is their due as human
persons with inherent dignity. Current debates about life-sustaining treatment
suggest that our society's moral reflection is having difficulty keeping pace
with its technological progress.
A religious view of life has an important contribution to make to these modern
debates. Our Catholic tradition has developed a rich body of thought on these
questions, which affirms a duty to preserve human life but recognizes limits to
that duty.
Our first goal in making this statement is to reaffirm some basic principles of
our moral tradition, to assist Catholics and others in making treatment
decisions in accord with respect for God's gift of life.
These principles do not provide clear and final answers to all moral questions
that arise as individuals make difficult decisions. Catholic theologians may
differ on how best to apply moral principles to some questions not explicitly
resolved by the Church's teaching authority. Likewise, we understand that those
who must make serious health care decisions for themselves or for others face a
complexity of issues, circumstances, thoughts and emotions in each unique case.
This is the case with some questions involving the medically assisted provision
of nutrition and hydration to helpless patients -- those who are seriously ill,
disabled or persistently unconscious. These questions have been made more urgent
by widely publicized court cases and the public debate to which they have given
rise.
Our second purpose in issuing this statement, then, is to provide some
clarification of the moral issues involved in decisions about medically assisted
nutrition and hydration. We are fully aware that such guidance is not
necessarily final, because there are many unresolved medical and ethical
questions related to these issues and the continuing development of medical
technology will necessitate ongoing reflection. But these decisions already
confront patients, families and health care personnel every day. They arise
whenever competent patients make decisions about medically assisted nutrition
and hydration for their own present situation, when they consider signing an
advance directive such as a "living will" or health care proxy document, and
when families or other proxy decision makers make decisions about those
entrusted to their care. We offer guidance to those who, facing these issues,
might be confused by opinions that at times threaten to deny the inherent
dignity of human life. We therefore address our reflections first to those who
share our Judeo-Christian traditions, and secondly to others concerned about the
dignity and value of human life who seek guidance in making their own moral
decisions.
Moral Principles
The Judeo-Christian moral tradition celebrates life as the gift of a loving God,
and respects the life of each human being because each is made in the image and
likeness of God. As Christians we also believe we are redeemed by Christ and
called to share eternal life with Him. From these roots the Catholic tradition
has developed a distinctive approach to fostering and sustaining human life. Our
Church views life as a sacred trust, a gift over which we are given stewardship
and not absolute dominion. The Church thus opposes all direct attacks on
innocent life. As conscientious stewards we have a duty to preserve life, while
recognizing certain limits to that duty:
Because human life is the foundation for all other human goods, it has a special
value and significance. Life is "the first right of the human person" and "the
condition of all the others."[1]
All crimes against life, including "euthanasia or willful suicide," must be
opposed.[2] Euthanasia is "an action or an omission which of itself or by
intention causes death, in order that all suffering may in this way be
eliminated." Its terms of reference are to be found "in the intention of the
will and in the methods used."[3] Thus defined, euthanasia is an attack on life
which no one has a right to make or request, and which no government or other
human authority can legitimately recommend or permit. Although individual guilt
may be reduced or absent because of suffering or emotional factors that cloud
the conscience, this does not change the objective wrongfulness of the act. It
should also be recognized that an apparent plea for death may really be a plea
for help and love.
Suffering is a fact of human life, and has special significance for the
Christian as an opportunity to share in Christ's redemptive suffering.
Nevertheless there is nothing wrong in trying to relieve someone's suffering; in
fact it is a positive good to do so, as long as one does not intentionally cause
death or interfere with other moral and religious duties.[4]
Everyone has the duty to care for his or her own life and health and to seek
necessary medical care from others, but this does not mean that all possible
remedies must be used in all circumstances. One is not obliged to use either
"extraordinary" means or "disproportionate" means of preserving life -- that is,
means which are understood as offering no reasonable hope of benefit or as
involving excessive burdens. Decisions regarding such means are complex, and
should ordinarily be made by the patient in consultation with his or her family,
chaplain or pastor, and physician when that is possible.[5]
In the final stage of dying one is not obliged to prolong the life of a patient
by every possible means: "When inevitable death is imminent in spite of the
means used, it is permitted in conscience to take the decision to refuse forms
of treatment that would only secure a precarious and burdensome prolongation of
life, so long as the normal care due to the sick person in similar cases is not
interrupted."[6]
While affirming life as a gift of God, the Church recognizes that death is
unavoidable and that it can open the door to eternal life. Thus, "without in any
way hastening the hour of death," the dying person should accept its reality and
prepare for it emotionally and spiritually.[7]
Decisions regarding human life must respect the demands of justice, viewing each
human being as our neighbor and avoiding all discrimination based on age or
dependency.[8] A human being has "a unique dignity and an independent value,
from the moment of conception and in every stage of development, whatever his or
her physical condition." In particular, "the disabled person (whether the
disability be the result of a congenital handicap, chronic illness or accident,
or from mental or physical deficiency, and whatever the severity of the
disability) is a fully human subject, with the corresponding innate, sacred and
inviolable rights." First among these is "the fundamental and inalienable right
to life."[9]
The dignity and value of the human person, which lie at the foundation of the
Church's teaching on the right to life, also provide a basis for any just social
order. Not only to become more Christian, but to become more truly human,
society should protect the right to life through its laws and other
policies.[10]
While these principles grow out of
a specific religious tradition, they appeal to a common respect for the dignity
of the human person. We commend them to all people of good will.

Introduction Questions
Questions about Medically Assisted Nutrition and
Hydration
In what follows we apply these well-established moral principles to the
difficult issue of providing medically assisted nutrition and hydration to
persons who are seriously ill, disabled or persistently unconscious. We
recognize the complexity involved in applying these principles to individual
cases and acknowledge that, at this time and on this particular issue, our
applications do not have the same authority as the principles themselves.
Is the withholding or withdrawing of medically assisted nutrition and
hydration always a direct killing?
In answering this question one should avoid two extremes.
First, it is wrong to say that this could not be a matter of killing simply
because it involves an omission rather than a positive action. In fact a
deliberate omission may be an effective and certain way to kill, especially to
kill someone weakened by illness. Catholic teaching condemns as euthanasia "an
action or an omission which of itself or by intention causes death, in order
that all suffering may in this way be eliminated." Thus "euthanasia includes not
only active mercy killing but also the omission of treatment when the purpose of
the omission is to kill the patient."[11]
Second, we should not assume that all or most decisions to withhold or withdraw
medically assisted nutrition and hydration are attempts to cause death. To be
sure, any patient will die if all nutrition and hydration are withheld.[12] But
sometimes other causes are at work -- for example, the patient may be imminently
dying, whether feeding takes place or not, from an already existing terminal
condition. At other times, although the shortening of the patient's life is one
foreseeable result of an omission, the real purpose of the omission was to
relieve the patient of a particular procedure that was of limited usefulness to
the patient or unreasonably burdensome for the patient and the patient's family
or care-givers. This kind of decision should not be equated with a decision to
kill or with suicide.
The harsh reality is that some who propose withdrawal of nutrition and hydration
from certain patients do directly intend to bring about a patient's death, and
would even prefer a change in the law to allow for what they see as more "quick
and painless" means to cause death.[13] In other words, nutrition and hydration
(whether orally administered or medically assisted) are sometimes withdrawn not
because a patient is dying, but precisely because a patient is not dying (or not
dying quickly) and someone believes it would be better if he or she did,
generally because the patient is perceived as having an unacceptably low
"quality of life" or as imposing burdens on others.[14]
When deciding whether to withhold or withdraw medically assisted nutrition and
hydration, or other forms of life support, we are called by our moral tradition
to ask ourselves: What will my decision do for this patient? And what am I
trying to achieve by doing it? We must be sure that it is not our intent to
cause the patient's death -- either for its own sake or as a means to achieving
some other goal such as the relief of suffering.
Is medically assisted nutrition and hydration a form of "treatment" or
"care"?
Catholic teaching provides that a person in the final stages of dying need not
accept "forms of treatment that would only secure a precarious and burdensome
prolongation of life," but should still receive "the normal care due to the sick
person in similar cases."[15] All patients deserve to receive normal care out of
respect for their inherent dignity as persons. As Pope John Paul II has said, a
decision to forgo "purely experimental or ineffective interventions" does not
"dispense from the valid therapeutic task of sustaining life or from assistance
with the normal means of sustaining life. Science, even when it is unable to
heal, can and should care for and assist the sick."[16] But the teaching of the
Church has not resolved the question whether medically assisted nutrition and
hydration should always be seen as a form of normal care.[17]
Almost everyone agrees that oral feeding, when it can be accepted and
assimilated by a patient, is a form of care owed to all helpless people.
Christians should be especially sensitive to this obligation, because giving
food and drink to those in need is an important expression of Christian love and
concern (Mt. 10:42 and 25:35; Mk. 9:41). But our obligations become less clear
when adequate nutrition and hydration require the skills of trained medical
personnel and the use of technologies that may be perceived as very burdensome
-- that is, as intrusive, painful or repugnant. Such factors vary from one type
of feeding procedure to another, and from one patient to another, making it
difficult to classify all feeding procedures as either "care" or "treatment."
Perhaps this dilemma should be viewed in a broader context. Even medical
"treatments" are morally obligatory when they are "ordinary" means--that is, if
they provide a reasonable hope of benefit and do not involve excessive burdens.
Therefore we believe people should make decisions in light of a simple and
fundamental insight: Out of respect for the dignity of the human person, we are
obliged to preserve our own lives, and help others preserve theirs, by the use
of means that have a reasonable hope of sustaining life without imposing
unreasonable burdens on those we seek to help, that is, on the patient and his
or her family and community.
We must therefore address the question of benefits and burdens next, recognizing
that a full moral analysis is only possible when one knows the effects of a
given procedure on a particular patient.
What are the benefits of medically assisted nutrition and hydration?
According to international codes of medical ethics, a physician will see a
medical procedure as appropriate "if in his or her judgment it offers hope of
saving life, reestablishing health or alleviating suffering."[18]
Nutrition and hydration, whether provided in the usual way or with medical
assistance, do not by themselves remedy pathological conditions, except those
caused by dietary deficiencies. But patients benefit from them in several ways.
First, for all patients who can assimilate them, suitable food and fluids
sustain life, and providing them normally expresses loving concern and
solidarity with the helpless. Second, for patients being treated with the hope
of a cure, appropriate food and fluids are an important element of sound health
care. Third, even for patients who are imminently dying and incurable, food and
fluids can prevent the suffering that may arise from dehydration, hunger and
thirst.
The benefit of sustaining and fostering life is fundamental, because life is our
first gift from a loving God and the condition for receiving His other gifts.
But sometimes even food and fluids are no longer effective in providing this
benefit, because a patient has entered the final stage of a terminal condition.
At such times we should make the dying person as comfortable as possible and
provide nursing care and proper hygiene as well as companionship and appropriate
spiritual aid. Such a person may lose all desire for food and drink and even be
unable to ingest them.
Initiating medically assisted feeding or intravenous fluids in this case may
increase the patient's discomfort while providing no real benefit; ice chips or
sips of water may instead be appropriate to provide comfort and counteract the
adverse effects of dehydration.[19] Even in the case of the imminently dying
patient, of course, any action or omission that of itself or by intention causes
death is to be absolutely rejected.
As Christians who trust in the promise of eternal life, we recognize that death
does not have the final word. Accordingly we need not always prevent death until
the last possible moment; but we should never intentionally cause death or
abandon the dying person as though he or she were unworthy of care and respect.
What are the burdens of medically assisted nutrition and hydration?
Our tradition does not demand heroic measures in fulfilling the obligation to
sustain life. A person may legitimately refuse even procedures that effectively
prolong life, if he or she believes they would impose excessively grave burdens
on himself or herself, or on his or her family and community. Catholic
theologians have traditionally viewed medical treatment as excessively
burdensome if it is "too painful, too damaging to the patient's bodily self and
functioning, too psychologically repugnant to the patient, too restrictive of
the patient's liberty and preferred activities, too suppressive of the patient's
mental life, or too expensive."[20]
Because assessment of these burdens necessarily involves some subjective
judgments, a conscious and competent patient is generally the best judge of
whether a particular burden or risk is too grave to be tolerated in his or her
own case. But because of the serious consequences of withdrawing all nutrition
and hydration, patients and those helping them make decisions should assess such
burdens or risks with special care.
Here we offer some brief reflections and cautions regarding the kinds of burdens
sometimes associated with medically assisted nutrition and hydration.
Physical risks and burdens
The risks and objective complications of medically assisted nutrition and
hydration will depend on the procedure used and the condition of the patient. In
a given case a feeding procedure may become harmful or even life-threatening.
(These medical data are discussed at length in an Appendix to this paper.)
If the risks and burdens of a particular feeding procedure are deemed serious
enough to warrant withdrawing it, we should not automatically deprive the
patient of all nutrition and hydration but should ask whether another procedure
is feasible that would be less burdensome. We say this because some helpless
patients, including some in a "persistent vegetative state," receive tube
feedings not because they cannot swallow food at all but because tube feeding is
less costly and difficult for health care personnel.[21]
Moreover, because burdens are assessed in relation to benefits, we should ask
whether the risks and discomfort of a feeding procedure are really excessive as
compared with the adverse effects of dehydration or malnutrition.
Psychological burdens on the patient
Many people see feeding tubes as frightening or even as bodily violations.
Assessments of such burdens are necessarily subjective; they should not be
dismissed on that account, but we offer some practical cautions to help prevent
abuse.
First, in keeping with our moral teaching against the intentional causing of
death by omission, one should distinguish between repugnance to a particular
procedure and repugnance to life itself. The latter may occur when a patient
views a life of helplessness and dependency on others as itself a heavy burden,
leading him or her to wish or even to pray for death. Especially in our
achievement-oriented society, the burden of living in such a condition may seem
to outweigh any possible benefit of medical treatment and even lead a person to
despair. But we should not assume that the burdens in such a case always
outweigh the benefits; for the sufferer, given good counseling and spiritual
support, may be brought again to appreciate the precious gift of life.
Second, our tradition recognizes that when treatment decisions are made,
"account will have to be taken of the reasonable wishes of the patient and the
patient's family, as also of the advice of the doctors who are specially
competent in the matter."[22] The word "reasonable" is important here. Good
health care providers will try to help patients assess psychological burdens
with full information and without undue fear of unfamiliar procedures.[23] A
well-trained and compassionate hospital chaplain can provide valuable personal
and spiritual support to patients and families facing these difficult
situations.
Third, we should not assume that a feeding procedure is inherently repugnant to
all patients without specific evidence. In contrast to Americans' general
distaste for the idea of being supported by "tubes and machines," some studies
indicate surprisingly favorable views of medically assisted nutrition and
hydration among patients and families with actual experience of such
procedures.[24]
Economic and other burdens on care-givers
While some balk at the idea, in principle cost can be a valid factor in
decisions about life support. For example, money spent on expensive treatment
for one family member may be money otherwise needed for food, housing and other
necessities for the rest of the family. Here, also, we offer some cautions.
First, particularly when a form of treatment "carries a risk or is burdensome"
on other grounds, a critically ill person may have a legitimate and altruistic
desire "not to impose excessive expense on the family or the community."[25]
Even for altruistic reasons a patient should not directly intend his or her own
death by malnutrition or dehydration, but may accept an earlier death as a
consequence of his or her refusal of an unreasonably expensive treatment.
Decisions by others to deny an incompetent patient medically assisted nutrition
and hydration for reasons of cost raise additional concerns about justice to the
individual patient, who could wrongly be deprived of life itself to serve the
less fundamental needs of others.
Second, we do not think individual decisions about medically assisted nutrition
and hydration should be determined by macro-economic concerns such as national
budget priorities and the high cost of health care. These social problems are
serious, but it is by no means established that they require depriving
chronically ill and helpless patients of effective and easily tolerated measures
that they need to survive.[26]
Third, tube feeding alone is generally not very expensive and may cost no more
than oral feeding.[27] What is seen by many as a grave financial and emotional
burden on care-givers is the total long-term care of severely debilitated
patients, who may survive for many years with no life support except medically
assisted nutrition and hydration and nursing care.
The difficulties families may face in this regard, and their need for improved
financial and other assistance from the rest of society, should not be
underestimated. While caring for a helpless loved one can provide many
intangible benefits to family members and bring them closer together, the
responsibilities of care can also strain even close and loving family
relationships; complex medical decisions must be made under emotionally
difficult circumstances not easily appreciated by those who have never faced
such situations.
Even here, however, we must try to think through carefully what we intend by
withdrawing medically assisted nutrition and hydration. Are we deliberately
trying to make sure that the patient dies, in order to relieve care-givers of
the financial and emotional burdens that will fall upon them if the patient
survives? Are we really implementing a decision to withdraw all other forms of
care, precisely because the patient offers so little response to the efforts of
care-givers? Decisions like these seem to reach beyond the weighing of burdens
and benefits of medically assisted nutrition and hydration as such.
In the context of official Church teaching, it is not yet clear to what extent
we may assess the burden of a patient's total care rather than the burden of a
particular treatment when we seek to refuse "burdensome" life support. On a
practical level, those seeking to make good decisions might assure themselves of
their own intentions by asking: Does my decision aim at relieving the patient of
a particularly grave burden imposed by medically assisted nutrition and
hydration? Or does it aim to avoid the total burden of caring for the patient?
If so, does it achieve this aim by deliberately bringing about his or her death?
Rather than leaving families to confront such dilemmas alone, society and
government should improve their assistance to families whose financial and
emotional resources are strained by long-term care of loved ones.[28]
What role should "quality of life" play in our decisions?
Financial and emotional burdens are willingly endured by most families to raise
their children or to care for mentally aware but weak and elderly family
members. It is sometimes argued that we need not endure comparable burdens to
feed and care for persons with severe mental and physical disabilities, because
their low "quality of life" makes it unnecessary or pointless to preserve their
lives.[29]
But this argument -- even when it seems motivated by a humanitarian concern to
reduce suffering and hardship -- ignores the equal dignity and sanctity of all
human life. Its key assumption -- that people with disabilities necessarily
enjoy life less than others or lack the potential to lead meaningful lives -- is
also mistaken.[30] Where suffering does exist, society's response should not be
to neglect or eliminate the lives of people with disabilities, but to help
correct their inadequate living conditions.[31] Very often the worst threat to a
good "quality of life" for these people is not the disability itself, but the
prejudicial attitudes of others--attitudes based on the idea that a life with
serious disabilities is not worth living.[32]
This being said, our moral tradition allows for three ways in which the "quality
of life" of a seriously ill patient is relevant to treatment decisions:
Consistent with respect for the inherent sanctity of life, we should relieve
needless suffering and support morally acceptable ways of improving each
patient's quality of life.[33]
One may legitimately refuse a treatment because it would itself create an
impairment imposing new serious burdens or risks on the patient. This decision
to avoid the new burdens or risks created by a treatment is not the same as
directly intending to end life in order to avoid the burden of living in a
disabled state.[34]
Sometimes a disabling condition may directly influence the benefits and burdens
of a specific treatment for a particular patient. For example, a confused or
demented patient may find medically assisted nutrition and hydration more
frightening and burdensome than other patients do because he or she cannot
understand what it is. The patient may even repeatedly pull out feeding tubes,
requiring burdensome physical restraints if this form of feeding is to be
continued. In such cases, ways of alleviating such special burdens should be
explored before concluding that they justify withholding all food and fluids
needed to sustain life.
These humane considerations are quite different from a "quality of life" ethic
that would judge individuals with disabilities or limited potential as not
worthy of care or respect. It is one thing to withhold a procedure because it
would impose new disabilities on a patient, and quite another thing to say that
patients who already have such disabilities should not have their lives
preserved. A means considered ordinary or proportionate for other patients
should not be considered extraordinary or disproportionate for severely impaired
patients solely because of a judgment that their lives are not worth living.
In short, while considerations regarding a person's quality of life have some
validity in weighing the burdens and benefits of medical treatment, at the
present time in our society judgments about the quality of life are sometimes
used to promote euthanasia. The Church must emphasize the sanctity of life of
each person as a fundamental principle in all moral decision-making.
Do persistently unconscious patients represent a special case?
Even Catholics who accept the same basic moral principles may strongly disagree
on how to apply them to patients who appear to be persistently unconscious --
that is, those who are in a permanent coma or a "persistent vegetative state"
(PVS).[35] Some moral questions in this area have not been explicitly resolved
by the Church's teaching authority.
On some points there is wide agreement among Catholic theologians:
An unconscious patient must be treated as a living human person with inherent
dignity and value. Direct killing of such a patient is as morally reprehensible
as the direct killing of anyone else. Even the medical terminology used to
describe these patients as "vegetative" unfortunately tends to obscure this
vitally important point, inviting speculation that a patient in this state is a
"vegetable" or a subhuman animal.[36]
The area of legitimate controversy does not concern patients with conditions
like mental retardation, senility, dementia or even temporary unconsciousness.
Where serious disagreement begins is with the patient who has been diagnosed as
completely and permanently unconscious after careful testing over a period of
weeks or months.
Some moral theologians argue that a particular form of care or treatment is
morally obligatory only when its benefits outweigh its burdens to a patient or
the care providers. In weighing burdens, they say, the total burden of a
procedure and the consequent requirements of care must be taken into account. If
no benefit can be demonstrated, the procedure, whatever its burdens, cannot be
obligatory. These moralists also hold that the chief criterion to determine the
benefit of a procedure cannot be merely that it prolongs physical life, since
physical life is not an absolute good but is relative to the spiritual good of
the person. They assert that the spiritual good of the person is union with God,
which can be advanced only by human acts, i.e., conscious, free acts. Since the
best current medical opinion holds that persons in the persistent vegetative
state (PVS) are incapable now or in the future of conscious, free human acts,
these moralists conclude that, when careful diagnosis verifies this condition,
it is not obligatory to prolong life by such interventions as a respirator,
antibiotics, or medically assisted hydration and nutrition. To decide to omit
non-obligatory care, therefore, is not to intend the patient's death, but only
to avoid the burden of the procedure. Hence, though foreseen, the patient's
death is to be attributed to the patient's pathological condition and not to the
omission of care. Therefore, these theologians conclude, while it is always
wrong directly to intend or cause the death of such patients, the natural dying
process which would have occurred without these interventions may be permitted
to proceed.
While this rationale is convincing to some, it is not theologically conclusive
and we are not persuaded by it. In fact, other theologians argue cogently that
theological inquiry could lead one to a more carefully limited conclusion.
These moral theologians argue that while particular treatments can be judged
useless or burdensome, it is morally questionable and would create a dangerous
precedent to imply that any human life is not a positive good or "benefit." They
emphasize that while life is not the highest good, it is always and everywhere a
basic good of the human person and not merely a means to other goods. They
further assert that if the "burden" one is trying to relieve by discontinuing
medically assisted nutrition and hydration is the burden of remaining alive in
the allegedly undignified condition of PVS, such a decision is unacceptable,
because one's intent is only achieved by deliberately ensuring the patient's
death from malnutrition or dehydration. Finally, these moralists suggest that
PVS is best seen as an extreme form of mental and physical disability -- one
whose causes, nature and prognosis are as yet imperfectly understood -- and not
as a terminal illness or fatal pathology from which patients should generally be
allowed to die. Because the patient's life can often be sustained indefinitely
by medically assisted nutrition and hydration that is not unreasonably risky or
burdensome for that patient, they say, we are not dealing here with a case where
"inevitable death is imminent in spite of the means used."[37] Rather, because
the patient will die in a few days if medically assisted nutrition and hydration
are discontinued,[38] but can often live a long time if they are provided, the
inherent dignity and worth of the human person obligates us to provide this
patient with care and support.
Further complicating this debate is a disagreement over what responsible
Catholics should do in the absence of a final resolution of this question. Some
point to our moral tradition of probabilism, which would allow individuals to
follow the appropriate moral analysis that they find persuasive. Others point to
the principle that in cases where one might risk unjustly depriving someone of
life, we should take the safer course.
In the face of the uncertainties and unresolved medical and theological issues,
it is important to defend and preserve important values. On the one hand, there
is a concern that patients and families should not be subjected to unnecessary
burdens, ineffective treatments and indignities when death is approaching. On
the other hand, it is important to ensure that the inherent dignity of human
persons, even those who are persistently unconscious, is respected, and that no
one is deprived of nutrition and hydration with the intent of bringing on his or
her death.
It is not easy to arrive at a single answer to some of the real and personal
dilemmas involved in this issue. In study, prayer and compassion we continue to
reflect on this issue and hope to discover additional information that will lead
to its ultimate resolution.
In the meantime, at a practical level, we are concerned that withdrawal of all
life support, including nutrition and hydration, not be viewed as appropriate or
automatically indicated for the entire class of PVS patients simply because of a
judgment that they are beyond the reach of medical treatment that would restore
consciousness. We note the current absence of conclusive scientific data on the
causes and implications of different degrees of brain damage, on the PVS
patient's ability to experience pain, and on the reliability of prognoses for
many such patients.[39] We do know that many of these patients have a good
prognosis for long-term survival when given medically assisted nutrition and
hydration, and a certain prognosis for death otherwise -- and we know that many
in our society view such an early death as a positive good for a patient in this
condition. Therefore we are gravely concerned about current attitudes and policy
trends in our society that would too easily dismiss patients without apparent
mental faculties as non-persons or as undeserving of human care and concern. In
this climate, even legitimate moral arguments intended to have a careful and
limited application can easily be misinterpreted, broadened and abused by others
to erode respect for the lives of some of our society's most helpless members.
In light of these concerns, it is our considered judgment that while legitimate
Catholic moral debate continues, decisions about these patients should be guided
by a presumption in favor of medically assisted nutrition and hydration. A
decision to discontinue such measures should be made in light of a careful
assessment of the burdens and benefits of nutrition and hydration for the
individual patient and his or her family and community. Such measures must not
be withdrawn in order to cause death, but they may be withdrawn if they offer no
reasonable hope of sustaining life or pose excessive risks or burdens. We also
believe that social and health care policies should be carefully framed so that
these patients are not routinely classified as "terminal" or as prime candidates
for the discontinuance of even minimal means of life support.
Who should make decisions about medically assisted nutrition and hydration?
"Who decides?" In our society many believe this is the most important or even
the only important question regarding this issue; and many understand it in
terms of who has legal status to decide. Our Catholic tradition is more
concerned with the principles for good moral decision-making, which apply to
everyone involved in a decision. Some general observations are appropriate here.
A competent patient is the primary decision-maker
about his or her own health care, and is in the best situation to judge how the
benefits and burdens of a particular procedure will be experienced. Ideally the
patient will act with the advice of loved ones, of health care personnel who
have expert knowledge of medical aspects of the case, and of pastoral counselors
who can help explore the moral issues and spiritual values involved. A patient
may wish to make known his or her general wishes about life support in advance;
such expressions cannot have the weight of a fully informed decision made in the
actual circumstances of an illness, but can help guide others in the event of a
later state of in competency.[40] Morally even the patient making decisions for
himself or herself is bound by norms that prohibit the directly intended causing
of death through action or omission, and by the distinction between ordinary and
extraordinary means.
When a patient is not competent to make his or her own decisions, a proxy
decision-maker who shares the patient's moral convictions, such as a family
member or guardian, may be designated to represent the patient's interests and
interpret his or her wishes. Here, too, moral limits remain relevant -- that is,
morally the proxy may not deliberately cause a patient's death or refuse what is
clearly ordinary means, even if he or she believes the patient would have made
such a decision.
Health care personnel should generally follow the reasonable wishes of patient
or family, but must also consult their own consciences when participating in
these decisions. A physician or nurse told to participate in a course of action
that he or she views as clearly immoral has a right and responsibility either to
refuse to participate in this course of action or to withdraw from the case, and
he or she should be given the opportunity to express the reasons for such
refusal in the appropriate forum. Social and legal policies must protect such
rights of conscience.
Finally, because these are matters of life and death for human persons, society
as a whole has a legitimate interest in responsible decision-making.[41]

point, but these do not have the force of official Church teaching. For
example, in 1985 a study group of the Pontifical Academy of Sciences

on him, including feeding." Pontifical Academy of Sciences, "The Artificial

27. A possible exception is total parenteral
feeding, which requires carefully prepared sterile formulas and more
intensive daily monitoring. Ironically, some current health care policies
may exert economic pressure in favor of TPN because it is easier to obtain
third-party reimbursement. Families may pay more for other forms of feeding
because some insurance companies do not see them as "medical treatment." See

35. Coma and persistent vegetative state are not the same. Coma,
strictly speaking, is generally not a long term condition, for within a few
weeks a comatose patient usually dies, recovers, or reaches the plateau of a
persistent vegetative state. "Coma implies the absence of both arousal and
content. In terms of observable behavior, the comatose patient appears to be
asleep, but unlike the sleeping patient, he cannot be aroused from this
state . . . the patient in the vegetative state appears awake but shows no
evidence of content, either confused or appropriate. He often has sleep-wake
cycles but cannot demonstrate an awareness of himself or his environment."

Neurosciences (Churchill Livingstone 1983), Volume I, page 956.

38. Because patients need nutritional support to live during the
weeks and months of observation required for a responsible assessment of
PVS, the cases discussed here involve decisions about discounting such
support rather than initiating it.
39. One recent scientific study of recovery rates followed up 84
patients with a firm diagnosis of PVS. Of these patients, "41% became
conscious by 6 months, 52% regained their consciousness by 1 year, and 58%
recovered consciousness within the 3-year follow-up interval." The study was
unable to identify "predictors of recovery from the vegetative state" --
that is, there is no established test by which physicians can tell in
advance which PVS patients will ultimately wake up. The data "do not exclude
the possibility of vegetative patients regaining consciousness after the
second year," though this "must be regarded as a rare event." Levin,

Moral Principles Conclusion
In this document we reaffirm moral principles that provide a basis for
responsible discussion of the morality of life support. We also offer tentative
guidance on how to apply these principles to the difficult issue of medically
assisted nutrition and hydration. We reject any omission of nutrition and
hydration intended to cause a patient's death. We hold for a presumption in
favor of providing medically assisted nutrition and hydration to patients who
need it, which presumption would yield in cases where such procedures have no
medically reasonable hope of sustaining life or pose excessive risks or burdens.
Recognizing that judgments about the benefits and burdens of medically assisted
nutrition and hydration in individual cases have a subjective element and are
generally best made by the patient directly involved, we also affirm a
legitimate role for families' love and guidance, health care professionals'
ethical concerns, and society's interest in preserving life and protecting the
helpless. In rejecting broadly permissive policies on withdrawal of nutrition
and hydration from vulnerable patients, we must also help ensure that the
burdens of caring for the helpless are more equitably shared throughout our
society. We recognize that this document is our first word, not our last word,
on some of the complex questions involved in this subject. We urge Catholics and
others concerned about the dignity of the human person to study these
reflections and participate in the continuing public discussion of how best to
address the needs of the helpless in our society.
Appendix
Technical Aspects of Medically
Assisted Nutrition and Hydration
Procedures
for providing nourishment and fluids to patients who cannot swallow food
orally are either "parenteral" (bypassing the
digestive tract) or "enteral" (using the digestive tract).
Parenteral or intravenous
feeding is generally considered "more hazardous and more expensive" than
enteral feeding.[42] It can be subdivided into peripheral intravenous
feeding (using a needle inserted into a peripheral vein) and central
intravenous feeding, also known as total parenteral feeding or
hyperalimentation (using a larger needle inserted into a central vein near
the heart). Peripheral intravenous lines can provide fluids and electrolytes
as well as some nutrients; they can maintain fluid balance and prevent
dehydration, but cannot provide adequate nutrition in the long term. [43]
Total parenteral feeding can provide a more adequate nutritional balance,
but poses significant risks to the patient and may involve costs an order of
magnitude higher than other methods of tube feeding. It is no longer
considered experimental, and has become "a mainstay for helping critically
ill patients to survive acute illnesses where the prognosis had previously
been nearly hopeless," but its feasibility for life-long maintenance of
patients without a functioning gastrointestinal tract has been
questioned.[44]
Because of the limited
usefulness of peripheral intravenous feeding and the special burdens of
total parenteral feeding--and because few patients so completely lack a
digestive system that they must depend on these measures for their sole
source of nutrition -- enteral tube feeding is the focus of the current
debate over medically assisted nutrition and hydration. Such methods are
used when a patient has a functioning digestive system but is unable or
unwilling to ingest food orally and/or to swallow. The most common routes
for enteral tube feeding are nasogastric (introducing a thin plastic tube
through the nasal cavity to reach into the stomach), gastrostomy (surgical
insertion of a tube through the abdominal wall into the stomach), and
jejunostomy (surgical insertion of a tube through the abdominal wall into
the small intestine).[45] These methods are the primary focus of this
document.
Each method of enteral tube
feeding has potential side-effects. For example, nasogastric tubes must be
inserted and monitored carefully so they will not introduce food or fluids
into the lungs. They may also irritate sensitive tissues and create
discomfort; confused or angry patients may sometimes try to remove them, and
efforts to restrain a patient to prevent this can impose additional
discomfort and other burdens. On the positive side, insertion of these tubes
requires no surgery and only a modicum of training.[46]
Gastrostomy and jejunostomy
tubes are better tolerated by many patients in need of long-term feeding.
Their most serious physical burdens arise from the fact that their insertion
requires surgery using local or general anesthesia, which involves some risk
of infection and other complications. Once the surgical procedure is
completed, these tubes can often be maintained without serious pain or
medical complications, and confused patients do not often attempt to remove
them.[47]

eventually collapse after a period of intravenous feeding, and will collapse
much faster if complex nutrients such as proteins are included in the
formula. See U.S. Congress, Office of Technology Assessment,

47. Major, page 22; OTA, page 282. Many ethicists observe that there
is no morally significant difference in principle between withdrawing a
life-sustaining procedure and failing to initiate it. However, surgically
implanting a feeding tube and maintaining it once implanted may involve a
different proportion of benefit to burden, because the transient risks of
the initial surgical procedure will not continue
or recur during routine maintenance of the tube.
