Under what circumstances is implied consent typically recognized?

Implied consent is recognized primarily when a patient's actions indicate agreement to a treatment or procedure, even if they do not verbally express that consent. This concept is based on the assumption that if a patient shows signs of understanding and acceptance, either through their behavior or by participating in the treatment process, consent to proceed is granted. For example, if a patient presents themselves for a dental procedure and sits in the treatment chair or does not object when asked for permission, this behavior can be interpreted as an implicit understanding and acceptance of the treatment being proposed.

In contrast, explicit consent documented in a patient’s file, verbal communication, or circumstances where a patient is unable to communicate do not fall under the definition of implied consent. Explicit consent is a more formal acknowledgment, while verbal communication requires a clear exchange of information and agreement. Additionally, when a patient cannot communicate—due to unconsciousness or severe impairment—different protocols for obtaining consent would apply, often requiring a surrogate decision-maker or legal representative to give consent on behalf of the patient. Thus, the essence of implied consent hinges on behaviors that suggest agreement rather than specific, documented, or expressed permissions.
