We sought to determine how delirium subtyped by arousal affected 6-month function and cognition in acutely ill older patients. ⋯ Delirium with normal arousal, as opposed to delirium with decreased or increased arousal, was the only arousal subtype significantly associated with worsening 6-month function and cognition. Subtyping delirium by arousal may have important prognostic value.
