Zorluk: OrtaInformed Consent and Refusal

A 42-year-old woman is evaluated in the intensive care unit for a severe asthma exacerbation. Despite aggressive treatment with systemic corticosteroids, continuous nebulized bronchodilators, and non-invasive positive pressure ventilation, she develops worsening hypercapnic respiratory failure. The physician strongly recommends endotracheal intubation and mechanical ventilation. The patient is awake, alert, and communicates clearly. She adamantly refuses intubation, stating, 'I watched my mother suffer on a ventilator for months before she died. I will never let that happen to me. I understand I might die without it, but I accept that risk.' Her arterial blood gas shows a pH of 7.21, pCO2 of 68 mm Hg, and pO2 of 55 mm Hg on 100% oxygen. Her sensorium remains fully intact, and she consistently expresses her reasoning. Her husband arrives, becomes extremely distressed, and insists that the medical team intubate her immediately to save her life. Which of the following is the most appropriate next step in management?

  1. A
    Request an emergent psychiatric consultation to formally determine legal competence.
  2. B
    Proceed with immediate endotracheal intubation under the doctrine of implied consent.
  3. Document the refusal, respect the patient's decision, and continue maximal accepted non-invasive medical therapy.Cevap
  4. D
    Obtain informed consent from the husband to authorize the mechanical ventilation.
  5. E
    Discontinue all current medical interventions and arrange for immediate hospice discharge.

Cevap

Document the refusal, respect the patient's decision, and continue maximal accepted non-invasive medical therapy.
The correct action is to document the refusal, respect the patient's decision, and continue maximal accepted non-invasive medical therapy. A capacitated adult has the absolute right to refuse any medical treatment, including life-saving interventions. This patient clearly demonstrates clinical decision-making capacity: she understands her diagnosis, the proposed intervention, and the consequences of refusal (including death), and she uses logical reasoning based on her personal values to arrive at her choice. When a patient has capacity, their autonomous decision overrides the wishes of family members or surrogates. The physician should respect her refusal while continuing other supportive care she has not refused.

Adım Adım Çözüm

1
Evaluate the patient's clinical decision-making capacity.
The patient demonstrates intact capacity because she understands her condition, appreciates the risks of refusing treatment (including death), and provides a rational explanation based on her values.
Capacity is the primary prerequisite for a patient to refuse a life-saving medical intervention.
2
Assess the role of the family member.
The husband's demands to intubate cannot override the patient's refusal.
Surrogate decision-makers have no legal or ethical standing when the patient possesses decision-making capacity.
3
Determine the appropriate management plan.
The physician must honor the refusal for intubation while continuing to provide all other acceptable medical care.
Respect for autonomy dictates that a capacitated adult's medical choices must be honored, even if they result in death.
