Difficulty: HardInformed Consent and Refusal of Care

A palliative care consultation is requested for a 68-year-old man who is hospitalized with a malignant small bowel obstruction secondary to widely metastatic pancreatic adenocarcinoma. The patient is currently obtunded, responding only to deep painful stimuli, and lacks decision-making capacity. His medical record contains a legally executed durable power of attorney for healthcare (DPOA-HC) designating his longtime domestic partner as his healthcare surrogate. He also has a living will, signed seven years ago, explicitly stating he would not want artificial nutrition, hydration, or surgical interventions if he developed a terminal condition. The domestic partner requests that the medical team focus exclusively on comfort measures and decline both surgical decompression and total parenteral nutrition (TPN). Shortly after, the patient's adult son from a previous marriage arrives. He is distraught, argues that the living will is outdated since it was signed years before the cancer diagnosis, and demands that the team immediately initiate TPN and consult surgery. The son threatens to file a lawsuit if his father is not treated aggressively. Which of the following is the most appropriate next step in management?

  1. A
    Administer total parenteral nutrition temporarily until a hospital ethics committee can formally mediate the family dispute
  2. Honor the domestic partner's request and transition the patient to comfort-focused careAnswer
  3. C
    Follow the adult son's demands because he is a first-degree relative and legally supersedes a domestic partner
  4. D
    Transfer decision-making authority to the adult son because the living will was executed significantly prior to the current acute diagnosis
  5. E
    Seek a court-appointed emergency guardian to make healthcare decisions due to the threat of legal action from a direct family member

Answer

Honor the domestic partner's request and transition the patient to comfort-focused care.
The correct action is to honor the domestic partner's request for comfort care. When a patient lacks decision-making capacity, the medical team must turn to an advance directive or a surrogate. A Durable Power of Attorney for Healthcare (DPOA-HC) is a legal document in which a patient designates a specific person to make medical decisions on their behalf. This designated proxy supersedes all other family members, including first-degree relatives like adult children, regardless of the biological relationship. Furthermore, the domestic partner's decision strictly adheres to the principle of substituted judgment, as it perfectly aligns with the patient's own living will. The son's threat of legal action and his claim that the living will is 'outdated' do not invalidate the legal standing of the DPOA-HC or the advance directive.

Step-by-Step Solution

1
Assess the patient's current decision-making capacity.
The patient is obtunded and lacks decision-making capacity.
This establishes the clinical requirement for a surrogate decision-maker to direct medical care.
2
Identify the legal surrogate decision-maker.
The domestic partner is identified as the legal surrogate.
The patient has a valid durable power of attorney for healthcare (DPOA-HC). A legally appointed proxy supersedes the default state next-of-kin hierarchy (such as adult children).
3
Evaluate the surrogate's requested management against the patient's known wishes.
The partner's request for comfort care strictly aligns with the patient's living will.
Surrogates must use substituted judgment. The living will clearly refuses artificial nutrition and surgery in terminal states.
4
Determine the appropriate clinical action despite external pressure.
Proceed with comfort-focused care, declining TPN and surgery.
The threats of a disgruntled family member or the age of an advance directive do not invalidate a legally binding DPOA-HC or a documented living will.

Key Concept
