Difficulty: MediumEnd-of-Life Care Ethics

A 42-year-old man is brought to the emergency department after a high-speed motorcycle collision. He sustains a massive acute subdural hematoma with significant midline shift. Despite emergent neurosurgical decompression, he progresses to a deep coma and requires continuous mechanical ventilation. The neurology team determines that his prognosis for meaningful neurologic recovery is highly unlikely. The patient is legally divorced and does not have an advance directive or a designated healthcare proxy. Several individuals arrive at the hospital and express differing views on the goals of care. His fiancée, who has lived with him for the past four years, insists on proceeding with a tracheostomy and percutaneous endoscopic gastrostomy tube. His 19-year-old biological daughter, who lives in another state and visits rarely, states that her father explicitly told her he would "never want to live on machines" and requests withdrawal of mechanical ventilation. The patient's mother insists on continuing all life-sustaining measures based on her religious beliefs. His ex-wife agrees with the daughter's request. Which of the following is the most appropriate next step in managing this patient's care?

  1. Follow the 19-year-old daughter's request to withdraw mechanical ventilation.Answer
  2. B
    Obtain consent from the fiancée to perform the tracheostomy and gastrostomy.
  3. C
    Continue mechanical ventilation as requested by the patient's mother.
  4. D
    Transfer decision-making authority to the hospital ethics committee.
  5. E
    Request the ex-wife to provide substituted judgment for the patient.

Answer

Follow the 19-year-old daughter's request to withdraw mechanical ventilation.
The correct action is to follow the directive of the 19-year-old daughter. When a patient lacks decision-making capacity and has not designated a healthcare proxy, a default surrogate decision-maker must be identified using the state's legal hierarchy. The standard hierarchy prioritizes individuals in the following order: legal spouse, adult children, parents, adult siblings, and then other relatives. Because the patient is legally divorced, there is no legal spouse. Although the fiancée has lived with the patient for four years, unmarried partners do not automatically receive the legal rights of a spouse in most jurisdictions without a formal advance directive. Therefore, the patient's 19-year-old daughter (an adult) is the highest-ranking legal surrogate. The fact that she lives out of state and visits rarely does not invalidate her legal authority. Her decision to withdraw mechanical ventilation, based on substituted judgment (what the patient would have wanted), must be honored.

Step-by-Step Solution

1
Determine the patient's decision-making capacity and existence of advance directives.
The patient is comatose (lacks capacity) and has no written advance directive or designated healthcare proxy.
This establishes the need for a default surrogate decision-maker.
2
Identify all available individuals and their relationship to the patient.
Available individuals include a fiancée, a 19-year-old daughter, a mother, and an ex-wife.
Mapping the relationships is necessary to apply the legal surrogate hierarchy.
3
Apply the standard legal surrogate hierarchy to the available individuals.
The hierarchy is: Spouse > Adult Child > Parent > Adult Sibling. The ex-wife is legally severed. The fiancée is not a legal spouse. Therefore, the 19-year-old adult child is the highest-ranking surrogate.
Legal precedent requires physicians to follow the direction of the highest-ranking available surrogate when determining goals of care.
