Head injury accounts for approximately
one million patient attendances at
emergency departments in the UK each
year; 5% of these injuries are classified as
severe, 10% as moderate and 85% as minor
(Headway 2009). It is critical to make the
distinction between minor, moderate and
severe head injury because there is a degree
of morbidity associated with moderate and
severe trauma to the head (Headway 2009).
