The Informant (or source of information) provides information on a person that provides
relevant information, such as the parent of a comatose patient who describes the patient's
behavior prior to the onset of coma. An informant can be a person in one of two roles;
an person not formally identified in the system (e.g. a parent or guy on the street)
or an identified member of the care team. The non-formally identified informant bears
some formal or personal relationship to the patient and the nature of the relationship
with the patient can be captured.
