Other questions Once a medical treatment is started, can it be stopped?
Yes. There is no legal or ethical difference between withholding and withdrawing a medical treatment. Therefore, people who may want to try a potentially helpful treatment can do so without fear that, once started, it could not be removed. Professional organizations such as the American Medical Association, as well as the courts, have affirmed that it is ethical to discontinue medical treatments that do not benefit the patient. If the patient no longer wants a treatment, for any reason, providers are legally obligated to withdraw it.
In practice, however, caregivers might resist withdrawing a treatment once it has begun. A caregiver might believe he or she would be helping to cause death, even though the patient's condition is irreversible. Also, caregivers might be confused or misinformed about what the law requires and what constitutes ethical practice. They might mistakenly believe they cannot stop treatment, even with clear evidence that the patient would not want it. If a physician refuses to end treatment, the patient or family should find out the reason for the refusal.
When Nancy Levitt's mother was first diagnosed with dementia 14 years ago at age 78, the doctor told her she could safely drive to familiar places. But Levitt, 61, who volunteers at UCLA's Center on Aging in Los Angeles, was still nervous. Unexplained nicks and dents started appearing on her mother's car. She forgot where she parked. Levitt tried to discuss driving safety with her mother, but she angrily denied there was a problem. Then, she would forget their talks about driving altogether.
Do healthcare providers run any legal risk by honoring advance directives?
No. Most advance directive statutes state explicitly that providers run no legal risk for honoring valid advance directives. No healthcare provider has ever been successfully prosecuted for honoring a patient's request to stop treatment. In fact, providers might run more legal risk when imposing treatment against a person's or healthcare agent's wishes.
What if my healthcare provider will not honor my advance directives?
In many states, healthcare providers can refuse to honor advance directives for moral or religious reasons. Some of those states require such individuals be removed from the case and transfer care of the patient to someone who will honor the patient's request. But in practice a healthcare provider's refusal to honor an advance directive can cause difficulties. For example, it may be hard to find a physician or facility willing to accept the patient. For this reason, it is important to ask in advance if a healthcare provider has personal views or if an institution has any policy that would prevent them from honoring a person's legal right to refuse treatment.
