In your health care directive, you can express your wishes and feelings about medical treatment in as much detail as you choose. For example, in most cases you can:
Here, we briefly discuss some medical procedures that you should be familiar with before you provide directions about your care. Dry or off-putting as it may seem, it’s a good idea to at least read quickly through the sections below to gain a basic understanding of:
However, you may not need to get into even that much detail if you are already certain of any of the following:
When completing your health care instructions, consider your preferences about life-prolonging treatments or procedures. Many people need a little more information before answering these questions.
A life-prolonging procedure or treatment is one that would only prolong the process of dying or sustain a condition of permanent unconsciousness. In other words, the patient would die soon—or die without regaining meaningful consciousness—whether or not the treatment was administered. This section describes the most common life-prolonging treatments—a respirator, cardiopulmonary resuscitation (CPR), surgery and so on—in some detail.
Bear in mind that the types of medical procedures that are available will change over time. Technological advances mean that currently unfathomable procedures and treatments will become available and treatments that are now common will become obsolete. Also, the treatments that are available vary drastically depending on the sophistication of medical facilities.
Blood and blood products. Partial or full blood transfusions may be recommended to combat diseases that impair the blood system, to foster healing after a blood loss, or to replenish blood lost through surgery, disease or injury.
Cardiopulmonary resuscitation. CPR is used when a person’s heart or breathing has stopped. CPR includes applying physical pressure and using mouth-to-mouth resuscitation. Electrical shocks are also used if available. CPR is often accompanied by intravenous drugs used to normalize body systems. A final step in CPR is often attaching the patient to a respirator.
Diagnostic tests. Diagnostic tests are commonly used to evaluate urine, blood, and other body fluids and to check on all bodily functions. Diagnostic tests can include X-rays and more sophisticated tests of brain waves or other body systems. Some tests—including surgery—can be expensive, painful and invasive.
Dialysis. A dialysis machine is used to clean and add essential substances to the blood—through tubes placed in blood vessels or into the abdomen— when kidneys do not function properly. The entire cleansing process takes three or more hours and is performed on most dialysis patients two or three times a week. With portable dialysis machines, it is possible for some patients to have the procedure performed at home rather than in a hospital or other advanced care facility.
Drugs. The most common and most controversial drugs given to seriously ill or comatose patients are antibiotics—administered by mouth, through a feeding tube, or by injection. Antibiotics are used to arrest and squelch infectious diseases. Patients in very weakened conditions may not respond even to massive doses of antibiotics.
Many health care providers argue that infectious diseases can actually be a benefit to those in advanced stages of an illness, since they may render a patient unconscious, and presumably not in pain, or help to speed up the dying process. Others contend that if an antibiotic can eliminate symptoms of an illness, it is almost always the proper medical treatment.
Drugs may also be used for pain. If, within your health care directive, you state that you do not want drugs to prolong your life, they will still be administered for pain control unless you specifically indicate that you do not want them.
Respirator. A mechanical respirator or ventilator assists or takes over breathing for a patient by pumping air in and out of the lungs. Patients are connected to respirators either by a tube that goes through the mouth and throat into the lung or attaches directly to the lung surgically.
Respirators are often used to stabilize patients who are suffering from an acute trauma or breathing crisis, and they are removed as soon as they are no longer needed. If a respirator has been attached to a person who is terminally ill or in a permanent coma, however, most doctors will resist removing the machinery unless there is clear written direction that this is what the patient would want.
Surgery. Surgical procedures, such as amputation, are often used to stem the spread of life-threatening infections or to keep vital organs functioning. Major surgery such as a heart bypass is also typically performed on patients who are terminally ill or comatose. You might want to consider the cost, time spent recovering from the invasive surgery, and inevitability of death when deciding whether to include surgery in your final medical treatment.
If you are permanently comatose or close to death from a serious illness, you may not be able to survive without the administration of food and water. Unless you indicate that treatment should be withheld, doctors will provide you with a mix of nutrients and fluids through tubes inserted in a vein, into your stomach through your nose, or directly into your stomach through a surgical incision, depending on your condition.
Intravenous (IV) feeding, where fluids are introduced through a vein in an arm or a leg, is a short-term procedure. Tube feeding, however, can be carried on indefinitely.
Permanently unconscious patients can sometimes live for years with artificial feeding and hydration without regaining consciousness. If food and water are removed, death will occur in a relatively short time due to dehydration, rather than starvation. Such a course of action generally includes a plan of medication to keep the patient comfortable.
When you make your health care documents, you can indicate whether you want artificially administered food and water withheld or provided. This decision is difficult for many people. Keep in mind that as long as you are able to communicate your wishes, by whatever means, you will not be denied food and water if you want it.
If you want death to occur naturally—without life-prolonging intervention—it does not mean you must forgo treatment to alleviate pain or keep you comfortable. In fact, in your health care directive, you can state that you wish to receive any care that is necessary to keep you pain-free, unless you specifically state otherwise.
This type of care, sometimes known as “comfort care,” is now more commonly called “palliative care.” Rather than focusing on a cure or prolonging life, palliative care emphasizes quality of life and dignity by helping a patient to remain comfortable and free from pain until life ends naturally. Studies have shown that palliative care services are greatly appreciated by the family and friends of dying patients. Numerous organizations promote public awareness of palliative care options, and information about treatment options is widely available on the Internet. (See “Where to Get More Help,” below.) However, despite the wide recognition of the benefits of palliative care, a major nationwide study in 2002 revealed that relatively few people get the palliative care they should. Most hospitals do not have integrated palliative care plans among their treatment options. Very few doctors understand it well, and it is still not emphasized in medical training. More than a decade later, the benefits of palliative care have become more widely known and accepted, but it still does not get the attention it deserves. As a result, many people die in hospital intensive care units, sometimes in severe pain, not knowing their suffering could have been greatly eased. You may wish to spend some time educating yourself about palliative care so that you can discuss your wishes with your health care agent and your treatment providers. When you complete your health care directive, you will have the opportunity to express any particular wishes you have about palliative care.
For many people, the desire to direct what kind of medical care they want to receive is driven by a very specific event—watching a loved one die, having an unsatisfactory brush with the medical establishment, or preparing for serious surgery. Your ultimate decisions are likely to be influenced by factors such as your medical history, your knowledge of other people’s experiences with life-prolonging medical procedures, or your religious beliefs. If you are having great difficulty deciding about your preferences for medical care, take a few moments to figure out what’s getting in your way. If you are unsure about the meaning or specifics of a particular medical treatment, turn to a doctor you trust for a more complete explanation. If the impediment is fear of sickness or death, talk over your feelings with family members and friends.
