Under what circumstances can a patient be treated without consent in an emergency?

• A. Treat only after confirming surrogate consent.
• B. Treat immediately only with written consent.
• C. Never treat without consent.
• D. In life-threatening emergencies, implied consent applies; after stabilization, respect onward wishes.

Answer: (D)

In an emergency with a life-threatening condition, clinicians can treat without the patient’s consent because of implied consent. The idea is that a reasonable person would want life-saving care when they cannot participate in the decision, and delaying treatment could lead to serious harm or death. This allows immediate actions to stabilize the patient.

Once the patient is stabilized, respect for autonomy kicks back in: if there is an advance directive, living will, or previously expressed wishes, those must be followed. If a surrogate decision-maker is available, they should determine what the patient would have wanted (substituted judgment) or, if that’s not possible, decisions should be made in the patient’s best interests. If the patient regains capacity, they have the right to accept or refuse further treatment.

Written consent is not required in true emergencies, because time is critical to preserve life.
