Difficulty: HardInformed Consent and Refusal

A 45-year-old man is evaluated in the emergency department for a 4-day history of increasing pain, redness, and swelling on his right forearm. He has a medical history of bipolar disorder and hypertension. His temperature is 37.8°C (100.0°F), blood pressure is 135/85 mmHg, and pulse is 92/min. Examination reveals a 5-cm fluctuant, erythematous, and exquisitely tender mass on the volar aspect of the right forearm. The physician recommends an incision and drainage of the abscess. The physician clearly explains that without drainage, the infection could spread, potentially leading to sepsis, loss of the limb, or death. The patient listens and responds, 'I understand the infection could spread to my blood and kill me if you don't drain it. But I have a severe phobia of scalpels from a past trauma. I absolutely refuse any cutting. I will only take antibiotic pills.' The patient is alert, oriented, and exhibits linear thought processes. The nursing staff notes that the patient's sister is listed as his legally designated healthcare proxy in the electronic medical record. The physician contacts the sister, who states, 'He is not thinking clearly. I have his medical power of attorney. I authorize you to do the procedure.' Which of the following is the most appropriate next step in management?

  1. A
    Perform the incision and drainage because the sister's consent as healthcare proxy overrides his refusal
  2. B
    Request an urgent psychiatric consultation to legally declare the patient incompetent
  3. Document the patient's refusal, prescribe oral antibiotics, and arrange for close outpatient follow-upAnswer
  4. D
    Proceed with the incision and drainage under the emergency exception to informed consent
  5. E
    Admit the patient to the medical ward for intravenous antibiotics against his will

Answer

The most appropriate next step is to document the patient's refusal, prescribe oral antibiotics, and arrange for close outpatient follow-up.
The patient demonstrates intact clinical decision-making capacity because he can understand his diagnosis, appreciate the severe risks of refusing the incision and drainage (including potential limb loss and death), and communicate a clear choice based on his own values (phobia of scalpels). Having a psychiatric diagnosis, such as bipolar disorder, does not automatically impair capacity. Because the patient retains capacity, his designated healthcare proxy remains inactive and cannot override his decisions. Therefore, the physician must respect his refusal and provide the best alternative care that the patient is willing to accept, which in this case is oral antibiotics with close follow-up.

Step-by-Step Solution

1
Evaluate the patient's decision-making capacity.
The patient demonstrates clinical capacity by understanding his diagnosis, the proposed treatment, the severe risks of refusal, and clearly communicating his choice based on his values.
A patient's right to refuse treatment depends primarily on their clinical capacity, not their psychiatric history.
2
Determine the legal status and authority of the surrogate decision-maker.
The sister is the designated healthcare proxy, but this authority is only activated when the patient loses decision-making capacity.
Surrogates cannot override the wishes of a capacitated patient.
3
Formulate a management plan that respects the patient's autonomy.
The physician must honor the patient's refusal of the incision and drainage.
Forcing the procedure would constitute medical battery.
4
Select the best alternative treatment.
Prescribe oral antibiotics and ensure close follow-up.
Even when a patient refuses the optimal treatment, the physician maintains a duty of care to offer the best acceptable alternative.

Key Concept

A designated healthcare proxy is only activated when a patient loses clinical decision-making capacity. A capacitated patient has the right to refuse any medical intervention, regardless of proxy disagreement or the presence of a psychiatric diagnosis.
