The American Society of Anesthesia score was an independent predictor of 90-day mortality as
well as low functional status at one year in 720 patients presenting to a single center with
moderate to severe brain injury. When used in conjunction with other prognosticating tools such
as the Trauma and Injury Severity Score, it increased the prognostic value of these scales.
