Mental Capacity and informed consent
Consent refers to a person’s voluntary assent to a particular action, decision or interaction. There are many different types of consent. These include:
- Implied consent – where no verbal or written consent has been given, but an action by the individual in question suggests their agreement. For example, if a patient offers their arm to have their blood pressure taken.
- Informed consent – requires an explicit understanding of all the relevant facts, including risks and available alternatives. Usually, information is provided in order to help the person to understand what is proposed and why. This type of consent is often associated with medical procedures in healthcare settings; it is also often formalised with a physical signature on a consent form.
