What constitutes expressed consent in a medical context?

Expressed consent in a medical context refers to the clear communication of a patient's agreement to a proposed medical treatment or procedure. This can be conveyed through verbal affirmation or through non-verbal actions that demonstrate understanding and agreement. The key aspect of expressed consent is that it must be intentional and unambiguous, indicating that the patient is aware of and agrees to the treatment being provided.

In situations where a healthcare provider discusses a procedure with a patient, the patient can verbally affirm their consent, or they might nod or otherwise indicate their agreement non-verbally. This form of consent is essential for respecting patient autonomy and ensuring that individuals have control over their medical decisions.

Other options do not fully encompass the definition of expressed consent. Written documentation is one form of consent but is not the only approach. Assumed consent applies primarily in emergencies and situations where the patient is unconscious or unable to provide consent. Informed consent typically requires a discussion about the risks and benefits of a procedure, rather than just the act of agreeing, making it broader than the concept of expressed consent. Thus, verbal or non-verbal actions indicating consent most accurately define expressed consent in a medical context.
