Difficulty: MediumInformed Consent and Refusal of Care

A 47-year-old man with end-stage liver disease due to chronic hepatitis C is brought to the emergency department with massive hematemesis. On arrival, he is lethargic, severely confused, and unable to participate in medical decision-making. The clinical team determines that he requires an emergent upper endoscopy and potentially a transjugular intrahepatic portosystemic shunt (TIPS) procedure to control the life-threatening variceal bleeding. The patient's medical record contains a valid advance directive executed one year ago that explicitly names his domestic partner as his healthcare agent. When contacted by telephone, the domestic partner states, 'He told me he never wanted any more invasive procedures if he got to this point. Please just keep him comfortable.' Shortly after, the patient's parents arrive at the hospital. They are legally married and state they are his biological next of kin. Upon learning of the partner's decision, the parents become angry and demand the medical team proceed with the life-saving procedures immediately. Which of the following is the most appropriate next step in management?

  1. Cancel the procedures and initiate comfort measures as directed by the domestic partner.Answer
  2. B
    Proceed with the procedures based on the parents' directive because biological relatives supersede unmarried partners.
  3. C
    Perform the procedures under the doctrine of emergency implied consent to stabilize the patient.
  4. D
    Provide blood transfusions to maintain hemodynamics while seeking an emergency court injunction.
  5. E
    Consult the hospital ethics committee to legally reassign decision-making authority to the parents.

Answer

The correct answer is to cancel the procedures and initiate comfort measures as directed by the domestic partner.
The correct answer is to cancel the procedures and initiate comfort measures as directed by the domestic partner. When a patient lacks decision-making capacity, medical decisions must be made by a surrogate. The legal hierarchy of surrogate decision-makers strictly dictates that a formally appointed healthcare proxy (agent) supersedes all other default legal next-of-kin, including legal spouses, adult children, and parents. Because the patient established an advance directive explicitly naming his domestic partner as his proxy, the partner has full, overriding legal authority to make medical decisions on his behalf. The parents, despite being biological relatives, have no legal standing to override the appointed proxy's decision. Therefore, the physician must honor the proxy's directive to transition to comfort care, even in a life-threatening emergency.

Step-by-Step Solution

1
Assess the patient's decision-making capacity.
The patient is lethargic and encephalopathic, confirming he lacks the capacity to make his own medical decisions.
Before relying on any surrogate, it must be established clinically that the patient cannot participate in the informed consent process.
2
Identify the appropriate legal surrogate decision-maker.
The patient has an advance directive naming his domestic partner as his healthcare agent (proxy).
A legally appointed healthcare proxy holds the highest authority in medical decision-making, superseding all default biological next-of-kin.
3
Determine the clinical plan based on the legal surrogate's directive.
The proxy refuses the invasive procedures and requests comfort measures, which must be honored.
The physician is legally and ethically obligated to follow the valid proxy's directives, regardless of objections from other family members.
