Which of the following best describes the criteria for legally valid informed consent?

• A. Patient signature; Provider signature; Witness signature; Freely given
• B. Patient signature; Provider signature; Freely given; Obtained by provider
• C. Patient signature; Family signature; Witness signature; Freely given
• D. Patient signature; Provider signature; Witness signature; Informed

Answer: (A)

Legally valid informed consent hinges on a voluntary, informed decision made by a capable patient and properly documented. The best description includes the patient’s signature to confirm agreement, the clinician’s signature to show that the discussion and disclosure occurred and consent was obtained, and a witness’s signature to provide an independent record that the process happened and the patient’s decision was voluntary. The phrase “freely given” emphasizes there was no coercion, duress, or undue influence.

Family signatures aren’t appropriate substitutes for the patient’s own consent unless a legal representative is authorized, and simply labeling consent as “informed” doesn’t capture the necessary documentation and affirmation of voluntariness. Obtaining consent is about the patient’s autonomous agreement, supported by proper documentation from the clinician and, when used, a witness.
