Zorluk: OrtaAdvance Directives and End-of-Life Care

A 68-year-old woman is admitted to the intensive care unit after suffering a massive intracerebral hemorrhage. She is comatose, requires mechanical ventilation, and lacks decision-making capacity. Her neurologic prognosis is deemed irreversible. The patient has a legally valid, written advance directive (living will) specifying that she does not want life-sustaining treatments, including mechanical ventilation, in the event of an irreversible neurologic injury. Her son, who is her legally appointed healthcare proxy, arrives at the hospital. After being updated on her prognosis, he states, "I know what her living will says, but as her proxy, I am overriding it. Keep her on the ventilator; I am not ready to let her go." Which of the following is the most appropriate next step in management?

  1. Explain to the son that the living will must be honored and prepare to withdraw mechanical ventilationCevap
  2. B
    Defer to the son's decision and continue mechanical ventilation indefinitely
  3. C
    Request a court injunction to remove the son as the designated healthcare proxy
  4. D
    Identify another family member to act as the surrogate decision-maker
  5. E
    Convene the hospital ethics committee to determine the patient's best interests

Cevap

Explain to the son that the living will must be honored and prepare to withdraw mechanical ventilation
The ethical principle of autonomy allows competent patients to direct their future medical care through advance directives. A living will provides clear, written instructions regarding a patient's preferences for end-of-life care. While a healthcare proxy is appointed to make decisions on the patient's behalf, their primary duty is to apply the principle of substituted judgment (acting as the patient would act). Consequently, a surrogate decision-maker cannot override a patient's clear, applicable, and documented wishes in a valid living will. Because this patient's living will explicitly refuses mechanical ventilation in the event of an irreversible neurologic injury, her written wishes supersede her son's demands. The physician should respectfully explain this legal and ethical framework to the son and proceed with honoring the patient's directive.

Adım Adım Çözüm

1
Assess the patient's decision-making capacity and the availability of advance directives.
The patient lacks capacity but has a valid written living will addressing her current irreversible condition.
Determines the foundation for medical decision-making based on patient autonomy.
2
Evaluate the surrogate's demands against the patient's written directive.
The healthcare proxy (son) is requesting interventions that directly contradict the patient's explicit written wishes.
Identifies a conflict between substituted judgment (proxy) and established patient autonomy (living will).
3
Determine the legal and ethical hierarchy of decision-making.
A clear, applicable written living will supersedes the contrary demands of a healthcare proxy.
Respects the primary ethical principle of patient autonomy, guiding the appropriate clinical action.
