Difficulty: HardDecision-Making Capacity

A 52-year-old woman with a 25-year history of treatment-resistant schizophrenia is evaluated in the clinic following a recent colonoscopy that revealed a large, obstructing adenocarcinoma of the ascending colon. The surgical oncology team recommends an urgent bowel resection. During the discussion, the patient appears disheveled and occasionally mumbles to herself. She correctly identifies her diagnosis, stating, "I have a tumor that will block my intestines and cause me to die." However, she declines the surgery. When asked for her reasoning, she says, "My father had the same surgery, and he spent his last six months in the ICU with tubes everywhere. I want to die peacefully at home, even if it happens sooner." She acknowledges that the voices she hears are currently telling her that the hospital food is poisoned, but she explicitly states, "I'm not refusing because of the voices; I just don't want the surgery." Which of the following is the most appropriate next step in management?

  1. A
    Conclude that she lacks capacity based on her active hallucinations and override her refusal
  2. B
    Request a judicial review to formally revoke her medical decision-making rights
  3. C
    Identify and contact a surrogate decision-maker according to the state-specific legal hierarchy
  4. Honor her wishes and transition her care to a symptom-management approachAnswer
  5. E
    Transfer the patient to the inpatient psychiatric unit for involuntary treatment

Answer

Honor her wishes and transition her care to a symptom-management approach.
This patient clearly demonstrates the four required pillars of decision-making capacity: she understands her medical condition (colon cancer), expresses a definitive choice (refusing surgery), appreciates the gravity of the consequences (acknowledges she will die without it), and provides logical, coherent reasoning (wanting to avoid a prolonged, painful ICU course like her father). Although she has a long-standing history of schizophrenia and is currently experiencing auditory hallucinations, her psychiatric symptoms are not driving her medical decision. Decision-making capacity is inherently decision-specific. Because her rationale for refusing the surgery is grounded in personal values and past experiences rather than delusional thinking, her capacity remains intact. Therefore, her autonomous decision must be respected, and the appropriate next step is to align her medical care with her goals, which involves transitioning to palliative or symptom-management care.

Step-by-Step Solution

1
Evaluate the four components of decision-making capacity.
The patient demonstrates understanding (knows she has a tumor), expresses a choice (declines surgery), appreciates the consequences (acknowledges it will cause her to die), and provides logical reasoning (wishes to avoid her father's ICU experience).
Capacity must be assessed systematically using standard criteria regardless of psychiatric history.
2
Analyze the impact of the patient's active psychosis on her specific medical decision.
While the patient is actively hallucinating about poisoned hospital food, this delusion is entirely disconnected from her reasoning for refusing surgery.
A psychiatric diagnosis or active psychosis only negates capacity if the psychiatric symptoms directly impair the specific decision being made.
3
Determine the most appropriate management based on the capacity assessment.
The patient has intact clinical capacity; therefore, her autonomous refusal of life-prolonging intervention must be respected.
Competent adults have the absolute right to refuse any medical treatment, even if that refusal will result in death.

Key Concept

Patients with severe psychiatric illnesses, including active psychosis, retain decision-making capacity as long as their psychiatric symptoms do not impair their understanding, appreciation, or reasoning for the specific medical decision at hand.
