Shared decision making occurs when someone needs help with making some or all decisions. It concerns the continuous involvement of an individual other than the person whose decision it is. In terms of the decision making as it is being considered in this course, the person should be included as much as possible whether or not they have capacity. As far as possible, the decisions of a person who lacks mental capacity should be shared decisions, rather than decisions made on their behalf by someone else.
The list below gives examples of people who may be involved in helping someone who lacks mental capacity to make decisions. The primary decision maker is the person who lacks mental capacity. Usually, the more complex the decision, the greater the need to involve people with expertise in mental capacity, who are in the lower half of the list, although this is not a requirement.
