Short Tilte:Acute confusion following traumatic brain injury
Year, Volume, Issue, Page(s):04, 18, 2, 131-142
Study examined the incidence and course of acute confusion or delirium in patients with traumatic brain injury in an acute neurorehabilitation setting. Eighty-five patients were evaluated using measures of motor restlessness (Agitated Behavior Scale), cognition (Cognitive Test for Delirium), orientation (Galveston Orientation and Amnesia Test), and delirium (Delirium Rating Scale). Evaluation scores, demographic variables, and injury characteristics of subjects who met the criteria for delirium were compared to those who did not. Results showed that 59 subjects met the criteria for delirium on initial evaluation and 42 of those resolved delirium during rehabilitation. Multivariable logistic regression analyses revealed significant unique associations of the Galveston Orientation and Amnesia Test, the Delirium Rating Scale, the Cognitive Test for Delirium, and time elapsed since injury with delirium status. Authors conclude that acute confusion is common and has a complex neurobehavioral presentation that is not adequately characterized with a single measure.
