Difficulty: HardAdvance Directives and Surrogate Decision Making

A 45-year-old man with end-stage alcoholic cirrhosis and refractory hepatic encephalopathy is admitted to the intensive care unit with severe variceal bleeding. Despite emergent endoscopic banding and maximal medical therapy, he develops progressive multiorgan failure. He is intubated, comatose, and lacks decision-making capacity. The critical care team determines that continued aggressive interventions are non-beneficial and wishes to discuss transitioning to comfort-focused care.

Two individuals arrive at the hospital, both claiming decision-making authority:
1. The patient's legally married wife, from whom he has been separated (but not legally divorced) for two years. She presents a legally valid "General Durable Power of Attorney" executed three years ago, designating her as the agent for all his financial and property affairs. She insists on continued aggressive life-sustaining treatment.
2. The patient's close friend. He presents a legally valid "Durable Power of Attorney for Healthcare" executed one year ago, explicitly designating him as the patient's healthcare proxy. The friend requests transition to comfort-focused care, citing the patient's previously expressed wishes to avoid prolonged mechanical ventilation.

The wife argues that her status as the legal spouse, combined with her General Power of Attorney, legally supersedes a document naming a non-family member.

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

  1. A
    Continue aggressive life-sustaining treatment as directed by the wife because spousal rights override non-relative proxy designations in the statutory hierarchy.
  2. B
    Continue aggressive life-sustaining treatment as directed by the wife because a General Durable Power of Attorney encompasses medical decision-making authority.
  3. Transition the patient to comfort-focused care in accordance with the direction of the friend.Answer
  4. D
    Defer the transition to comfort-focused care and consult the hospital ethics committee to establish surrogate authority.
  5. E
    Defer the transition to comfort-focused care and petition for court-appointed guardianship due to the conflicting legal documents.

Answer

The physician should transition the patient to comfort-focused care in accordance with the direction of the friend, who is the legally designated healthcare proxy.
The correct action is to follow the directives of the designated healthcare proxy. When a patient lacks decision-making capacity, the physician must identify the lawful surrogate. The highest order of surrogate authority is a legally executed Durable Power of Attorney for Healthcare (DPOA-HC). By naming his friend in this document, the patient explicitly transferred his medical decision-making rights to the friend. This written designation legally supersedes the default statutory hierarchy (which would otherwise prioritize the spouse). Furthermore, the wife's General Durable Power of Attorney only grants her authority over the patient's financial and legal affairs; it does not authorize her to make medical decisions. Therefore, the friend is the sole legal surrogate, and his request for comfort care, which aligns with the patient's previously expressed wishes and medical appropriateness, must be honored.

Step-by-Step Solution

1
Assess the patient's capacity and need for a surrogate decision-maker.
The patient is intubated, comatose, and lacks decision-making capacity, requiring a surrogate.
Incapacitated patients require an authorized surrogate to make medical decisions on their behalf.
2
Evaluate the legal authority of the competing individuals.
The friend possesses a Durable Power of Attorney for Healthcare. The wife possesses a General (Financial) Power of Attorney and spousal status.
Different legal documents and relationships confer different types of authority.
3
Determine the highest-ranking legal authority for medical decisions.
The friend's Durable Power of Attorney for Healthcare explicitly grants medical decision-making authority. This legally supersedes the default statutory surrogate hierarchy (which would have prioritized the spouse) and the financial POA (which grants no medical authority).
A patient's explicit written designation of a healthcare proxy is the highest legal standard for surrogate authority.
4
Execute the decision made by the lawful surrogate.
Follow the friend's request to transition to comfort-focused care.
The physician has a legal and ethical obligation to follow the directives of the authorized healthcare proxy, provided the requests are medically appropriate.

Key Concept

A Durable Power of Attorney for Healthcare designates a proxy who holds ultimate medical decision-making authority, superseding both the default statutory next-of-kin hierarchy and any financial or general Power of Attorney documents.
