Difficulty: MediumInformed Consent and Refusal

A 38-year-old man with a 10-year history of schizoaffective disorder is evaluated in the surgical ward for a rapidly spreading necrotizing soft tissue infection of his right lower extremity. Intravenous antibiotics have been initiated, but the surgical team determines that an urgent right above-knee amputation is required to prevent death from overwhelming sepsis. The physician discusses the procedure, risks, benefits, and the certainty of death without surgery. The patient refuses the amputation, stating, "I understand that if I don't have this leg cut off, the infection will spread to my blood and I will die in a few days. But my body is a temple, and I refuse to be mutilated. I would rather die intact." He calmly repeats the physician's explanations accurately and demonstrates clear understanding of his prognosis. His thought processes are linear, and he denies any current auditory or visual hallucinations commanding him to refuse. His sister, who is his emergency contact, arrives and demands that the surgery be performed, stating, "He has a severe mental illness; he's clearly not competent to make this choice. You have to save his life." Which of the following is the most appropriate next step in management?

  1. Document the patient's informed refusal and continue with antibiotics and supportive careAnswer
  2. B
    Obtain consent for the amputation from the patient's sister as the surrogate decision-maker
  3. C
    Petition the local court for an emergency order declaring the patient legally incompetent
  4. D
    Place the patient on an involuntary psychiatric hold to facilitate the life-saving surgery
  5. E
    Discharge the patient from the hospital immediately against medical advice

Answer

Document the patient's informed refusal and continue with antibiotics and supportive care
The correct action is to respect the patient's autonomy, document his refusal, and continue offering whatever medical management he will accept. This patient demonstrates the four essential components of decision-making capacity: he communicates a clear choice, understands his diagnosis and the proposed treatment, appreciates the severe consequences of refusing (including death), and provides a rational explanation for his choice based on his personal values. A history of a psychiatric condition, such as schizoaffective disorder, does not automatically strip a patient of their right to make medical decisions. Because his refusal is not driven by an acute psychotic symptom (e.g., command hallucinations instructing him not to have surgery), his capacity remains intact. Therefore, his refusal of the amputation must be honored.

Step-by-Step Solution

1
Assess the patient's decision-making capacity regarding the proposed amputation.
The patient successfully communicates a choice, understands the relevant information, appreciates the medical consequences (including death), and reasons about his choice.
Capacity must be established before determining if a patient's refusal of life-saving treatment is valid.
2
Evaluate the impact of the patient's psychiatric history on his current capacity.
The patient's schizoaffective disorder is not currently impairing his judgment, as he has no command hallucinations or delusions driving this specific refusal.
A psychiatric diagnosis does not automatically equate to a lack of decision-making capacity.
3
Address the sister's request to override the patient's decision.
The sister's request is denied because surrogate decision-making is only invoked when a patient lacks capacity.
Patient autonomy takes precedence over family wishes when the patient has intact capacity.
4
Determine the appropriate ongoing management plan.
The physician honors the refusal and continues to provide the medical care the patient is willing to accept.
Physicians must respect capacitated refusals but also have a duty of non-abandonment, continuing to offer supportive care.
