Delirium
Delirium is a disturbance of attention and awareness, which develops over a short period of time. It is a change in a person’s baseline and fluctuates throughout the course of the day.1 Delirium can accompany almost any serious medical illness. It is an independent risk factor for increasing a person’s morbidity and mortality. Delirium is associated with an increased length of hospital stay and an increase in health care cost.2 There is growing literature to assist in the diagnosing and treatment of patients with delirium.
