Zorluk: ZorEnd-of-Life and Palliative Care

A 71-year-old man is evaluated in the hospital for a transition to comfort-focused care. He has a history of ischemic cardiomyopathy for which a left ventricular assist device (LVAD) was implanted as destination therapy three years ago. Two months ago, he was diagnosed with widely metastatic pancreatic adenocarcinoma and has experienced rapid functional decline. He is now completely bedbound, cachectic, and experiencing poorly controlled abdominal pain despite escalating doses of intravenous opioids. During a family meeting, the patient, who demonstrates clear decision-making capacity, requests to be discharged to home hospice. He also explicitly requests that his LVAD be deactivated once he arrives home, stating, "I am ready to die naturally, and I do not want this machine keeping my body alive anymore." The cardiology team expresses concern that turning off the implanted device is ethically and legally equivalent to physician-assisted suicide. Which of the following is the most appropriate next step in management?

  1. Arrange for home hospice discharge and coordinate with the palliative team to deactivate the LVAD at the patient's residence.Cevap
  2. B
    Decline the deactivation request, as intentionally disabling an internal device that replaces native organ function constitutes active euthanasia.
  3. C
    Defer the deactivation until a court-appointed psychiatrist formally confirms the patient is legally competent to refuse life support.
  4. D
    Transfer the patient to an inpatient hospice unit, as withdrawal of advanced mechanical circulatory support is prohibited in the home setting.
  5. E
    Obtain written authorization from the patient's next of kin, as surrogate consent is mandatory when withdrawing destination therapy devices.

Cevap

Arrange for home hospice discharge and coordinate with the palliative team to deactivate the LVAD at the patient's residence.
The correct response is to honor the patient's request to be discharged home and coordinate the deactivation of the LVAD with the hospice team. Ethically and legally, an LVAD is a life-sustaining medical treatment. There is no distinction between withholding or withdrawing an LVAD and other forms of life support, such as mechanical ventilation, hemodialysis, or artificial nutrition. A patient with decision-making capacity has the absolute right to refuse or request withdrawal of any medical intervention, even if doing so will predictably result in death. Turning off the device allows the patient's underlying severe cardiomyopathy to follow its natural course; it does not constitute active euthanasia or physician-assisted suicide. Furthermore, LVAD deactivation can be safely managed in the home hospice setting provided that preemptive symptom management (e.g., administering opioids and benzodiazepines for anticipated dyspnea and anxiety) is arranged.

Adım Adım Çözüm

1
Assess the patient's medical condition and prognosis.
The patient has a terminal malignancy with weeks to live and is suffering from refractory symptoms.
Establishes the clinical context for transitioning to comfort measures only.
2
Evaluate the patient's capacity and request.
The patient has clear decision-making capacity and requests LVAD deactivation upon returning home.
A patient with capacity has the absolute legal and ethical right to refuse any medical treatment, including life-sustaining therapy.
3
Apply ethical principles to the specific device.
LVADs are considered life-sustaining medical treatments, legally and ethically equivalent to mechanical ventilators or hemodialysis.
Withdrawing an LVAD allows the underlying disease to take its natural course; it is distinct from physician-assisted suicide or active euthanasia.
4
Determine the appropriate care setting.
Discharge to home hospice with coordinated deactivation is planned.
LVAD deactivation can safely and ethically be performed at home with appropriate hospice support and anticipatory symptom management protocols.
