For patients lacking capacity with no surrogate, which standard guides care?

• A. Best interest standard, aligned with patient values and medical judgment; involve ethics
• B. Follow physician's personal preferences
• C. Wait for a surrogate to be found before acting
• D. Auto treat as if patient chose the most aggressive option

Answer: (A)

When a patient cannot make decisions and has no surrogate, care is guided by what would be best for the patient overall. This best interest standard means weighing the likely benefits and burdens of treatments, considering what the patient would value or have wanted if known, and applying clinical judgment to promote the patient’s well-being and dignity. If there are any prior wishes, advance directives, or documented preferences, those inform the determination, and ethics input can help ensure the choice aligns with ethical and legal standards.

Relying on the physician’s personal preferences isn’t appropriate because decisions should be centered on the patient’s values and best interests, not one clinician’s viewpoint. Waiting indefinitely for a surrogate can delay needed care and cause harm. Automatically prescribing the most aggressive option ignores the patient’s values and the balance of benefits and burdens.
