Ethics and Alzheimer’s-Part Two: Feeding Tubes

In 1988 during the Nancy Cruzan case involving a young, non-terminally ill woman in a so-called “persistent vegetative state” whose parents wanted her feeding tube withdrawn so she would die, I was asked if I was going to feed my mother who had Alzheimer’s disease. At the time, my mother had no problems with eating but I knew the real question was about a possible feeding tube later on.

Ironically, I had just written an  op-ed on the Cruzan case titled “Feeding is not Extraordinary Care  and I pointed out that if the withdrawal of food and water from people with severe brain injuries was accepted, the pool of potential victims would expand.

I was thinking about people like my mother and, sadly, I was right.

In 1993, just 3 years after Nancy Cruzan died a long 12 days after her feeding tube was removed, a letter in the Journal of the American Medical Association by Dr. Ezekiel Emanuel, one of the future architects of Obamacare, acknowledged that the actual proof purported to show that the Cruzan case met Missouri law requiring “clear and convincing evidence” that Ms. Cruzan would not want to live in a so-called “vegetative” state rested only on “fairly vague and insubstantial comments to other people”.

However, he noted that

“…increasingly it will be our collective determination as to what lives are worth living that will decide how incompetent patients are treated. We need to begin to articulate and justify these collective determinations.” (Emphasis added.) Source: The American Journal of Medicine January 1993 Volume 94 p. 115

ALZHEIMER’S AND FEEDING TUBES

When I was asked about whether I would feed my mother with Alzheimer’s, I gave the same answer I gave when my baby daughter Karen with Down Syndrome and a heart defect was critically ill in 1983: Their anticipated deaths must be from their conditions, not from deliberate starvation and dehydration.

In the end, neither one needed a feeding tube. My daughter’s kidneys and other organs shut down and, since food or water would cause worse fluid overload, Karen was not given extra fluid and her heart gave out a short time later. In my mother’s case, she eventually needed to be spoon-fed until she quietly died in her sleep.

As a former hospice and ICU nurse, these scenarios are very familiar to me. Multiple organ failure sometimes occurs with critical illness and dying patients often gradually lose their appetites as they approach death. In those cases, we would give what little these people want or need until death. But for people not dying or near death, we made sure that they had at least basic  medical care and the life essentials of food, clothing and shelter. This is-or used to be-simple common sense.

ALZHEIMER’S AS A FATE WORSE THAN DEATH

The easiest way to get people to accept death by starvation/dehydration is to get them to choose it for themselves even before they have a problem.

Thus, media stories of people and their families suffering tremendously because of Alzheimer’s are very persuasive. People fear becoming an economic and emotional burden on their families. Not surprisingly, many people then willingly check off feeding tubes and other medical treatments in their advance directives.

Position papers like that from the American Geriatrics Society and the Alzheimer’s Association can also paint a dark picture:

The Association asserts that research evidence support no medical benefit from feeding tubes in advance dementia and that feeding tubes may actually cause harm in the advanced state of Alzheimer’s. Additionally, it is ethically permissible to withhold nutrition and hydration artificially administer by  vein or gastric tube when the individual with Alzheimer’s or dementia is in the end stages of the disease and is no longer able to receive food and water by mouth

The presumption is that such a death is peaceful and painless when a person is assumed to be unaware in a “vegetative” or late Alzheimer’s state. However, Bobby Schindler has written an account of the reality  of a prolonged starvation/dehydration death on his sister Terri Schiavo that was hidden from the public.

“JOE’S” CASE

Several years ago, I cared for a man with early stage Alzheimer’s who had a serious pneumonia needing a ventilator for a couple of days. Afterwards, Joe (not his real name) was alert and cooperative but the ventilator tube unexpectedly affected his ability to swallow and speak easily. His family asked about a feeding tube and special swallow therapists to try to retrain his throat muscles so that he could eat and drink safely. That is how an even older friend of mine in the same situation but without Alzheimer’s was successfully treated recently.

However in Joe’s case, a neurologist was first called to evaluate Joe’s mental status. I was there as the doctor asked him questions like “How many fingers am I holding up?” The man answered the questions correctly but the neurologist immediately wrote for nothing by mouth including crucial blood pressure medications. He also then recommended no feeding tube to the family. No swallow therapy was ordered. Joe was never asked about this.

When I questioned the neurologist and pointed out that the man had given correct answers by nods and holding up the correct number of fingers when asked, the neurologist responded by saying that the man did not hold up his fingers “fast enough”!

This is the tragic reality when we judge some lives as not worth living.

UP CLOSE AND PERSONAL

One of my oldest friends, “Dr. Mary” (not her real name), is a pro-life doctor who asked me years ago to be her power of attorney for health care if she became incapacitated. She had never married and had no close relatives. She told me what she wanted, especially in light of the Nancy Cruzan case, and signed an advance directive available through our archdiocese.

My friend now has presumed Alzheimer’s dementia and she is now in the later stages. She can still feed herself, albeit somewhat messily. She no longer remembers my name or her friends’ names but she is delighted when we come.

At almost 90 and with inevitable death approaching, she now has a Do Not Resuscitate (DNR) order but her nursing home is well aware that this does not mean any reduction in care or attention.

Along with her other friends who visit and help, our goal now is to make Dr. Mary as happy and safe as possible. If she needs spoon-feeding, she will get it. All of us hope that Dr. Mary will never need a feeding tube but she will not be denied one if necessary.

But best of all, Dr. Mary will continue to receive our love until her Lord calls her home.

Can We Choose to Live?

In a 2016 study “What does “futility” mean? An empirical study of doctors’ perceptions” in the Medical Journal of Australia distilled this definition from the majority of responses:

Futile treatment is treatment that has only a very low chance of achieving meaningful benefit for the patient in terms of:

  • improving quality of life;

  • sufficiently prolonging life of acceptable quality; or

  • bringing benefits that outweigh the burdens of treatment

Alarmingly, the article also states: “Doctors may reach a view that treatment is futile, informed by their definition of futility and clinical indicators such as functional status, disease severity, and age.” (Emphasis added.)

Over 10 years ago, I wrote an article “Futility Policies and the Duty to Die” about little-known futility policies being promoted, even in Catholic hospitals. These policies allow doctors and ethics committees to overrule patients’ or families’ decisions to continue  care or treatment when a person’s prognosis or “quality of life” was considered too poor.

In February, I wrote about the still not passed Simon’s Law here in Missouri that exposed the secret futility policies that led to the death of Simon Crosier, a baby with Trisomy 18.

However, a couple of weeks ago, a horrified nurse friend showed me two health care directive she recently received as a patient. One was from a Catholic  health care facility and the other was a standard Missouri durable power of attorney directive . The wording in both made her question whether such futility policies were now being incorporated into such directives.

I understand her concern.

THE CATHOLIC  DURABLE POWER OF ATTORNEY FOR HEALTH CARE DIRECTIVE

A person signs such a directive in order to have a family member or other trusted person make health care decisions when they are incapacitated. An legally incapacitated person is  defined as  a “Person unable to make rational decisions or engage in responsible actions. Mental and/or physical deficiency, disability, illness, drug use causing temporary or permanent impairment.”

“Living wills” and other advance health care directives,  invented by so-called “right to die” groups, claimed to give people the power to choose at the end of life

Remembering the prolonged dehydration deaths of Nancy Cruzan and Terri Schiavo, two non-terminally ill but severely brain-injured women said to be in the so-called “persistent vegetative state”, a person might sign a directive but want to prevent such a terrible death for himself or herself.

However, while this Catholic directive has a section to make such a decision, it also an asterisked section attached to both withdrawal and refusal of withdrawal:

I DO NOT AUTHORIZE my Agent/Proxy to direct a health care provider to withhold or withdraw artificially supplied nutrition and hydration (including tube feeding of food and water) as  permitted by law.*

*(In a XXXXX health care facility, nutrition and hydration may be withheld or withdrawn if I have an irreversible condition which is end-state or terminal AND if the means of preserving my life have likely risks and burdens which outweigh the expected benefits or are disproportionate without a reasonable hope of benefit.) (Emphasis added)

Using such terms as “end-state or terminal”  could, for example, apply  not only to a “persistent vegetative state” but also to Alzheimer’s or other dementia. “Artificially supplied” could encompass a simple IV while the asterisked section inexplicably does not even include the words “artificially supplied” before the food and water.  Along with using terms like “disproportionate without a reasonable hope of benefit” without stating who makes that determination or what the criteria is for benefit, the average person could be understandably confused in a real life situation.

THE MISSOURI DURABLE POWER OF ATTORNEY DIRECTIVE

Many, if not most, Missouri hospitals have this directive.

This directive has a section stating:

If I am persistently unconscious or there is no reasonable expectation of my recovery from a seriously incapacitating or terminal illness or condition, I direct that all of the life-prolonging procedures that I have initialed below be withheld or withdrawn. (Emphasis added)

This list includes not only “artificially supplied nutrition and hydration” but also antibiotics, CPR and “all other life-prolonging medical or surgical procedures that are merely intended to keep me alive without reasonable hope of improving my condition or curing my illness or injury.” (Emphasis added) Note that, according to the directive, a person need not have a terminal illness or be in a coma to qualify for withdrawal.

The next section can seem reassuring if a person has qualms about a decision to withdraw treatment or care being made too quickly or influenced by age or disability.  However, the directive only states that such treatments or care may  be tried-at the doctor’s  discretion-for an undefined “reasonable”period of time before withdrawal. Unfortunately, this section also includes automatic consent to pain relief, even in dosages that can suppress breathing and appetite as in terminal sedation:

3. However, if my physician believes that any life-prolonging procedure may lead to a recovery significant to me as communicated by me or my Agent to my physician, then I direct my physician to try the treatment for a reasonable period of time.  If it does not cause my condition to improve, I direct the treatment to be withdrawn even if it shortens my life.  I also direct that I be given medical treatment to relieve pain or to provide comfort, even if such treatment might shorten or suppress my appetite or my breathing, or be habit-forming. (Emphasis added)

The Catholic health directive also includes this section, almost verbatim.

CONCLUSION

With the help of the media, mentally disabling conditions like Alzheimer’s are often portrayed to the public as a fate worse than death and a terrible burden on a family. Tragically, the “right to die” mentality has led many people to conclude that they should die if they develop such conditions or, if dying, that their death may be accelerated to spare their families.

As a nurse who has seen the problems with advance directives firsthand, I helped design my own durable power of attorney advance directive without exemptions or checkoffs that could be misused or misinterpreted. I also educated my husband and family about the medical ethics involved.

As I wrote in my blog Living with “Living Wills”, there are better alternatives available to the standard kinds of advance directives even though no directive is foolproof.

Adequately informed consent is required for legal consent to surgery. Shouldn’t advance directives that involve life or death be held to the same standard before signing?

 

 

LIVING WITH “LIVING WILLS”

In the early 1970s when I was a young ICU nurse, none of us medical professionals had even heard of a “living will”. There was a universal presumption for life and “quality of life” was something to be improved, not judged.

Nevertheless, sick people could and did refuse treatment and even check themselves out of the hospital against medical advice. When patients appeared to be dying, they or their families could agree to a “do not resuscitate” (DNR) order. Overly aggressive or useless treatments could be discouraged when such measures were considered medically futile or excessively burdensome for the patient. But one thing we didn’t do was offer to withhold or withdraw medical care like tube feedings to cause or hasten a patient’s death.

Unknown to us, all this began to change after Louis Kutner, a Chicago lawyer, wrote an article in the Indiana Law Journal titled Due Process of Euthanasia: The Living Will, A Proposal” in 1969. (emphasis added). By 1970, The Euthanasia Society of America (later renamed the Society for the Right to Die) distributed 60,000 living wills. In 1976, California passed the nation’s first “living will” law. Now, there are proposals to eventually include even physician-assisted suicide in “living wills”.

I use the common term “living will” to represent the wide variety of end of life documents that have evolved since the original “living will”, including the newest but problematic one called POLST (physician orders for life-sustaining treatment).

I wrote a 2001 article “Of Living Wills and Butterfly Ballots”   because I was concerned that many people were signing such documents with little knowledge of the history and problems with such documents that I witnessed as a nurse and ethics committee member. However, with the crucial help of a sympathetic media, court cases involving seriously brain-injured people like Terri Schiavo and government mandates such as the 1990 Patient Self-Determination Act have resulted in the heavy promotion of “living wills” as simple, worry-free documents. Now the federal government is set to begin paying healthcare providers for talking to all Medicare beneficiaries about such documents.

CAN “LIVING WILLS” BE HAZARDOUS TO YOUR HEALTH?

Recently, I talked to lawyers who expressed confusion and concern over the “living wills” they were asked to draw up. In addition, Medscape, a subscription website for medical professionals, and the American Medical News have published recent articles such as “Advance Directives May Be Hazardous to Your Health”  and “Clearing Up Confusion on Advance Directives”. The last article even warns

“misinterpretations of end-of-life documents too often result in lost lives or unwanted care” such as when “physicians incorrectly assume that DNR means not to treat a patient who is critically ill”.

When even doctors and lawyers are confused, there is a big problem. In the real world of medicine, I even heard some doctors say that if in doubt, it might be legally safer not to treat than to treat someone with a “living will” in an emergency because of lawsuits where a patient with a “living will” survived or had serious impairments.

SHOULD I EVEN HAVE A “LIVING WILL”?

When “living wills” first came out, I felt I was safer not to have one to make sure I received treatment. Later, I changed my mind. I felt it was safer to designate someone I trusted with the legal authority to make decisions if I was unable to speak for myself rather than just leave it to my family members, some of whom vigorously disagreed with my stance for feeding brain-injured people like Terri Schiavo.

I never tell people that they must or must not have a “living will” but everyone should be fully informed. I do encourage people to check out information sites like the Pro-Life Healthcare Alliance’s “Informed-A Guide to Critical Medical Decisions”  which has sections explaining ventilators, CPR (cardiopulmonary resuscitation), feeding tubes, misuse of opioids and sedatives as well as end of life considerations.

There are also several informative and protective “living will” documents from organizations like the Patients Rights Council and the American Life League. The National Right to Life Committee even has such documents online and specific to state laws.

SOME POINTS TO CONSIDER BEFORE SIGNING A “LIVING WILL” STYLE DOCUMENT

Here are some of my personal recommendations as a nurse before signing a standard “living will” or even a protective one.

1. Make sure the document is as short as possible, simple to understand and that the presumption for life is expressly stated so that if doctors are in doubt about your wishes, they should treat you.

What most people do not know is that “living will” style documents often go unread by doctors and nurses until a critical situation develops and time is of the essence. Even worse, some doctors and nurses still assume or misinterpret “living wills” as meaning the patient does not want treatment, especially if the patient is older or disabled.

2. Avoid vague terms like “significant recovery” and “terminal event” that have no objective medical standard and can easily be misinterpreted.

I’ve seen patients who have just had a stroke or head injury incorrectly judged “terminal” or “incurable by doctors. Such patients often get better with time and treatment. And, of course, any treatment that is medically futile or excessively burdensome to the patient can be ethically withdrawn later. I add the emphasis because now futility and burden are too often assumed to mean an inadequate “quality of life” or economic burden to the family or society.

3. Designate one person you trust to make your medical decisions with a backup person or persons.

Sometimes when only one person is the designated decision maker, he or she may be unavailable or incapacitated so a backup is important especially in a critical situation.

4. Consider not checking off particular treatments or conditions to be automatically refused.

Personally, I wanted a positive “living will” that only designates my decision maker and his/her right to make decisions about my care rather than signing a “living will” to refuse future treatment or set possible future conditions where I would want treatment stopped or withheld. Instead, I want all current options, risks and benefits of treatment fully explained to my decision maker based on my current condition.

5. Many “living wills” contain a section on pain with such sentences such as “I want my doctor to give me enough pain medicine to relieve my pain”. You might consider adding a phrase like “without hastening my death.”

I have seen unnecessarily high doses of pain medicine deliberately given to make a patient unconscious while food and water were stopped. Often, this was called “comfort care” instead of terminal/palliative sedation  but the result was hastening or causing death by dehydration and/or suppression of breathing.

Everyone wants and deserves adequate pain control at the end of life. Carefully increasing doses of pain medication and other measures work in virtually any situation and family members should advocate this for their loved ones.

CONCLUSION

There may be no perfect “living will” but as a former hospice nurse and family caregiver myself, I believe that dying people have a right to a good death with as few medical interventions as possible for comfort without deliberately hastening or causing death. The time before death may be short or long but I believe that people have the right to die at their own natural pace.

Death is not something to get over with as soon as possible. As some people with terminal illness have told me, they hated being treated as if they were already dead when they were still alive. They wanted to hear jokes, be with family and friends, go to church, etc. And since hearing is thought to be the last sense to go, I interacted with my dying patients in comas just as I did with my conscious patients.

The process of coming to terms with  death can be difficult at times but it also can be a meaningful time to review a life with all its joys and sorrows as well as a time for family and friends to show love, support and even healing.
