Zorluk: ZorEnd-of-Life and Palliative Care

An 82-year-old woman with advanced Lewy body dementia is admitted to the intensive care unit with septic shock secondary to aspiration pneumonia. Over the past 48 hours, despite maximal vasopressor support and targeted antimicrobial therapy, she has developed progressive multiorgan failure, including anuric acute kidney injury and severe lactic acidosis. She is completely unresponsive to noxious stimuli, and the medical team determines her condition is terminal. She does not have a formal advance directive or a designated healthcare proxy.

Her family is present at the bedside. Her husband of 50 years, who resides in an assisted living facility due to mild cognitive impairment, clearly and consistently articulates that his wife "never wanted to be kept alive by machines with no hope of recovery." He requests the withdrawal of all life-sustaining treatments. Her oldest son, who just arrived from out of state, demands that continuous renal replacement therapy be initiated immediately, arguing that his father's memory issues invalidate his decision-making ability.

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

  1. Acknowledge the husband as the primary surrogate and transition to comfort-focused careCevap
  2. B
    Seek a court order to determine the husband's legal competence before withdrawing support
  3. C
    Initiate continuous renal replacement therapy based on the son's demand for aggressive care
  4. D
    Arrange for immediate transfer to an outpatient hospice facility for palliative withdrawal of support
  5. E
    Begin a continuous intravenous morphine infusion to proactively prevent dyspnea during extubation

Cevap

Acknowledge the husband as the primary surrogate and transition to comfort-focused care
The most appropriate action is to honor the husband's decision and transition the patient to comfort-focused care. In the absence of a formal advance directive or designated healthcare proxy, the legal hierarchy of surrogate decision-makers universally places the spouse at the top, ahead of adult children. Although the husband has mild cognitive impairment, clinical decision-making capacity is decision-specific. Because he demonstrates the ability to understand the medical situation, articulate a clear choice, and apply his wife's known values to the current scenario, he retains the clinical capacity to act as her surrogate. The son's demands cannot override the legally recognized primary surrogate.

Adım Adım Çözüm

1
Evaluate the patient's clinical status and prognosis.
The patient is in terminal multiorgan failure with no realistic chance of meaningful recovery.
Establishing the medical reality is required before discussing goals of care and withdrawal of support.
2
Determine the appropriate surrogate decision-maker according to legal hierarchy.
The husband is the legal next of kin and primary surrogate, superseding the adult children.
In the absence of a designated proxy or advance directive, state laws universally place the spouse at the top of the surrogate hierarchy.
3
Assess the surrogate's clinical decision-making capacity.
Despite having mild cognitive impairment, the husband demonstrates a clear understanding of the medical facts and applies the patient's known values to the decision.
Capacity is decision-specific; mild dementia does not automatically preclude the ability to make medical decisions on behalf of another if the criteria for capacity are met.

Anahtar Kavram

In the absence of an advance directive, the spouse holds the highest priority as surrogate decision-maker. Mild cognitive impairment does not automatically invalidate a surrogate's clinical capacity, which is determined by a physician based on the individual's ability to understand the situation and articulate a choice consistent with the patient's values.
