Difficulty: MediumDecision-Making Capacity

A 42-year-old man with a history of schizophrenia is hospitalized for treatment of right foot osteomyelitis. Despite receiving intravenous antibiotics, the infection is progressing. The orthopedic surgery team recommends a partial foot amputation to prevent life-threatening sepsis. The patient refuses to sign the consent form for the surgery. He calmly states, "I understand that my foot is severely infected and that I might die from this infection without the surgery. However, I know the government implanted a tracking microchip in my foot bone. If the surgeons remove it, the government will immediately execute me." The patient is oriented to person, place, and time. His vital signs are stable, and there is no evidence of delirium. Which of the following is the most appropriate next step in management?

  1. A
    Petition the local court system to formally rule on the patient's legal competence
  2. B
    Cancel the surgery and transfer the patient to an inpatient psychiatric facility
  3. C
    Request an ethics committee review to determine who should make the decision
  4. Contact the patient's closest available relative to obtain surrogate consentAnswer
  5. E
    Honor the refusal because the patient accurately verbalizes the medical consequences

Answer

Contact the patient's closest available relative to obtain surrogate consent
The correct answer is to contact the patient's closest available relative to obtain surrogate consent. Decision-making capacity requires four elements: the ability to understand the information, express a choice, appreciate the significance of the information, and reason logically. Although this patient understands the diagnosis and the risk of death, his reasoning is entirely dictated by a fixed, false belief (delusion) directly related to the surgery. Therefore, he lacks capacity for this specific decision. Because osteomyelitis requiring amputation is urgent but typically allows a window of time to communicate with family, the physician should follow the standard legal hierarchy and seek surrogate consent.

Step-by-Step Solution

1
Assess the patient's decision-making capacity across all four pillars: understanding, expressing a choice, appreciation, and reasoning.
The patient understands the medical facts but fails the reasoning and appreciation pillars due to a fixed delusion directly impacting the decision.
Capacity is decision-specific and requires the ability to logically manipulate information without interference from active psychiatric symptoms.
2
Determine the legal status of the patient's refusal.
The refusal is invalid because the patient lacks capacity for this specific decision.
A patient without capacity cannot provide informed consent or a valid informed refusal.
3
Identify the next step for obtaining consent in an urgent, non-emergent setting.
Consent must be obtained from a legally authorized surrogate decision-maker.
Since the situation is urgent but allows time to contact family, the standard surrogate hierarchy must be utilized rather than relying on implied emergency consent.

Key Concept

Patients with psychiatric illness can lack decision-making capacity if their symptoms (e.g., delusions) directly impair their ability to reason about or appreciate a specific medical intervention, necessitating the use of a surrogate decision-maker.
