Zorluk: OrtaAdvance Directives and End-of-Life Care

A 58-year-old woman with widely metastatic breast cancer is admitted to the palliative care unit for management of intractable bone pain and severe dyspnea. She is intermittently confused, deeply somnolent, and currently lacks the capacity to make complex medical decisions. Her medical prognosis is poor, with an estimated survival of days to weeks. Two years ago, while fully competent, the patient executed a legal advance directive designating her longtime friend as her healthcare proxy. The document explicitly outlines her preference for comprehensive symptom management aimed at comfort, even if such measures inadvertently shorten her life. The designated proxy requests the initiation of a continuous intravenous morphine infusion to alleviate her distress. The patient's sister, who has been estranged for a decade but recently arrived at the hospital, vehemently opposes the infusion, demanding that it be withheld out of fear it will cause a fatal respiratory arrest. Which of the following is the most appropriate next step in management?

  1. A
    Consult the hospital ethics committee to formally authorize the infusion before proceeding
  2. B
    Defer to the sister's directive because biological next-of-kin legally supersede non-relative proxies
  3. Initiate the morphine infusion as directed by the designated healthcare proxyCevap
  4. D
    Withhold the morphine infusion and revoke the proxy's authority for requesting a potentially life-shortening intervention
  5. E
    Seek a court-appointed guardianship to resolve the dispute between the proxy and the sister

Cevap

The most appropriate next step is to initiate the morphine infusion as directed by the designated healthcare proxy.
The patient lacks decision-making capacity but has a legally valid advance directive appointing her friend as her healthcare proxy. In the hierarchy of surrogate decision-makers, a legally designated proxy explicitly chosen by the patient supersedes all default biological next-of-kin, including her sister. The proxy's request for a continuous morphine infusion directly aligns with the patient's documented wishes for symptom management. Furthermore, this intervention is ethically justified under the principle of double effect, which permits the administration of potentially life-shortening medications (such as high-dose opioids causing respiratory depression) provided the primary intention is the relief of severe suffering.

Adım Adım Çözüm

1
Determine the patient's decision-making capacity.
The patient is confused and somnolent, lacking the capacity to make medical decisions.
Capacity determines whether the patient can direct their own care or if a surrogate must be utilized.
2
Identify the appropriate surrogate decision-maker based on legal hierarchy.
The patient has a legally executed advance directive appointing her friend as her healthcare proxy.
A designated healthcare proxy holds the highest priority in the surrogate hierarchy, superseding biological next-of-kin such as the sister.
3
Evaluate the ethical validity of the proxy's request for high-dose opioids.
The request is ethically valid under the principle of double effect and aligns with the patient's documented wishes for comfort-focused care.
Medications may be administered to relieve severe suffering even if they carry a foreseeable secondary risk of hastening death, provided the primary intent is symptom relief.
