Capacity is obtained via written and verbal communication for all patients. Anyone who is over the age of 16 can be presumed to be able to have the capacity to consent to their own medical treatment unless concerns are raised. Anyone under the age of 16 can consent to their own treatment, as long as they are able to show that they can understand the implications of that treatment. Of course there will be people who are over 16 who will be unable to understand and make decisions, just as there will be people under 16 who are unable to consent. A full overview of our approach to consent can be found here.
