Difficulty: MediumEnd-of-Life and Palliative Care

A 78-year-old woman with advanced Alzheimer dementia is admitted to the medical intensive care unit with aspiration pneumonia and septic shock. She requires vasopressor support and noninvasive positive pressure ventilation. Despite broad-spectrum antibiotics and fluid resuscitation, her respiratory status continues to decline, and the care team considers endotracheal intubation. The patient is profoundly encephalopathic and lacks decision-making capacity. She does not have a designated healthcare proxy or an advance directive. The patient's family includes her 80-year-old husband and two adult daughters. The husband has a documented history of mild cognitive impairment. However, upon evaluation by the intensive care physician, the husband demonstrates a clear understanding of his wife's prognosis and the risks and benefits of intubation. He consistently expresses his rationale for choosing comfort-focused measures, citing his wife's previously expressed wishes to avoid mechanical ventilation. The two adult daughters strongly disagree with the husband and demand that their mother be intubated and fully resuscitated, arguing that their father's cognitive impairment invalidates his decision. Which of the following is the most appropriate next step in the management of this patient?

  1. Honor the husband's decision to transition to comfort-focused care because he has demonstrated clinical capacity.Answer
  2. B
    Transfer decision-making authority to the adult daughters because a diagnosis of cognitive impairment automatically precludes serving as a surrogate.
  3. C
    Obtain a formal psychiatric consultation to legally determine the husband's competence before implementing comfort measures.
  4. D
    Follow the directives of the adult daughters because adult offspring supersede a spouse with a neurologic diagnosis in the surrogate hierarchy.
  5. E
    Perform endotracheal intubation to maintain the patient's airway while awaiting a unanimous family consensus.

Answer

Honor the husband's decision to transition to comfort-focused care because he has demonstrated clinical capacity.
The husband holds the highest priority in the legal surrogate hierarchy. A diagnosis of mild cognitive impairment does not automatically preclude an individual from having clinical decision-making capacity. Because the intensive care physician has evaluated the husband and confirmed his ability to understand the prognosis, appreciate the risks and benefits, and reason through the options to arrive at a consistent choice, he possesses clinical capacity for this specific decision. Therefore, his directive to pursue comfort-focused care in alignment with the patient's values should be honored, despite the disagreement from the adult daughters.

Step-by-Step Solution

1
Identify the need for a surrogate decision-maker.
The patient lacks decision-making capacity and has no advance directive, so a legal surrogate must be identified.
Medical decisions cannot be made by the patient, requiring a prioritized family member.
2
Determine the legal surrogate hierarchy.
The spouse (husband) holds the highest priority, superseding the adult children.
State laws consistently prioritize spouses over adult children for medical decision-making when no proxy is designated.
3
Assess the husband's clinical capacity.
Despite his mild cognitive impairment, the husband demonstrates understanding, appreciation, reasoning, and consistent communication regarding this specific decision.
Capacity is decision-specific. A diagnosis of cognitive impairment does not automatically negate a person's clinical capacity.
4
Implement the valid surrogate's decision.
The care team should transition the patient to comfort-focused care.
The valid, capacitated surrogate's decision, which aligns with the patient's previously expressed wishes, must be honored over the objections of lower-priority family members.
