Difficulty: MediumInformed Consent and Refusal of Care

A 65-year-old man with advanced amyotrophic lateral sclerosis is brought to the emergency department after suffering a massive ischemic stroke. He is profoundly obtunded and requires intubation for airway protection upon arrival. The patient's electronic medical record contains a valid advance directive, completed one year ago when he was cognitively intact, explicitly stating he refuses intubation and mechanical ventilation under any circumstances. The document also legally designates his wife as his healthcare proxy. His wife arrives at the hospital in distress and states, "I know what his living will says, but I cannot bear to lose him today. Please keep him on the breathing machine until our children can fly in this weekend." Which of the following is the most appropriate next step in management?

  1. Arrange for extubation and transition the patient to comfort-focused careAnswer
  2. B
    Maintain mechanical ventilation until the children arrive as requested by the proxy
  3. C
    Request an urgent hospital ethics committee consultation before altering his respiratory support
  4. D
    Assess the wife's decision-making capacity given her acute emotional distress
  5. E
    Attempt to contact the children directly to serve as alternate surrogate decision-makers

Answer

Arrange for extubation and transition the patient to comfort-focused care
The correct answer is to arrange for extubation and transition to comfort-focused care. This patient has a valid, clearly written advance directive specifying he does not want mechanical ventilation under any circumstances. The core ethical and legal principle of patient autonomy dictates that a competent patient's prior written wishes must supersede the desires of their designated healthcare proxy or next-of-kin. The proxy's role is strictly to enact the patient's known wishes through substituted judgment, not to override them for personal or emotional reasons. Because the patient's explicit instructions refuse intubation, maintaining mechanical ventilation is a violation of his autonomy and constitutes medical battery. The physician is obligated to honor the advance directive.

Step-by-Step Solution

1
Evaluate the patient's current clinical status and decision-making capacity.
The patient is profoundly obtunded and lacks decision-making capacity.
Determining capacity is the first step in identifying who has the authority to make current medical decisions.
2
Review the medical record for advance care planning documents.
A valid advance directive is found explicitly refusing intubation and mechanical ventilation.
When a patient lacks capacity, previously expressed written wishes provide the strongest legal and ethical guidance.
3
Compare the surrogate's requests with the patient's advance directive.
The wife's request for continued mechanical ventilation directly contradicts the advance directive.
This identifies a conflict between the proxy's emotional desires and the patient's autonomous instructions.
4
Execute the medical plan that aligns with the highest standard of patient autonomy.
The medical team plans for extubation and comfort care.
A valid, explicit advance directive supersedes the contradictory requests of a healthcare proxy or next-of-kin.

Key Concept
