Difficulty: MediumAdvance Directives and Surrogate Decision Making

A 48-year-old man with advanced amyotrophic lateral sclerosis is admitted to the hospital with severe aspiration pneumonia and acute hypercapnic respiratory failure. On evaluation, he is lethargic, oriented only to person, and lacks medical decision-making capacity. The patient has a legally valid advance directive, executed two years ago while he had full capacity, which explicitly states, "I refuse intubation and mechanical ventilation under any circumstances." At that same time, he also designated his husband as his durable power of attorney for healthcare.

The patient's respiratory status worsens, and he is in impending respiratory arrest. His husband, who is at the bedside, becomes highly distressed and tells the physician, "I know what his living will says, but I cannot lose him today. I am his designated proxy, and I demand that you intubate him to save his life."

Which of the following is the most appropriate next step in management?

  1. A
    Intubate the patient, as the proxy's current demand supersedes the prior written directive
  2. B
    Intubate the patient under the emergency consent exception due to the immediate threat to life
  3. Withhold intubation, as the explicit written directive takes precedence over the proxy's demandAnswer
  4. D
    Withhold intubation and transfer proxy authority to the patient's parents
  5. E
    Convene an urgent ethics committee meeting before making a final decision on intubation

Answer

The most appropriate action is to withhold intubation, as the explicit written directive takes precedence over the proxy's demand.
The correct action is to withhold intubation, as the patient's explicit written directive takes precedence. When an incapacitated patient has a clear, applicable, and legally valid advance directive (living will), it functions as a direct extension of their autonomy. A designated healthcare proxy is ethically and legally bound by the 'substituted judgment' doctrine, meaning they must make decisions aligned with the patient's known wishes. A proxy cannot unilaterally override a patient's clear written refusal of life-sustaining treatment based on their own emotional distress or personal preferences.

Step-by-Step Solution

1
Assess the patient's clinical status and decision-making capacity.
The patient is lethargic, confused, and lacks capacity to make current medical decisions.
To determine whether the patient can direct his own care or if an advance directive/surrogate must be utilized.
2
Identify available advance directives and authorized decision-makers.
The patient has a clear living will refusing intubation and a legally designated healthcare proxy (his husband).
To establish the legal framework for subsequent medical interventions.
3
Resolve the conflict between the living will and the proxy's current demands.
The living will is followed, and intubation is withheld despite the husband's requests.
A designated proxy is bound by the substituted judgment doctrine and cannot override the patient's explicit, written autonomous choice.

Key Concept

A legally valid, explicit advance directive (living will) representing an incapacitated patient's autonomous choice supersedes the contradictory demands of a designated healthcare proxy.
