A-114 Predicting Long-Term Cognitive Outcomes From Acute Orientation Performance After Traumatic Brain Injury


 
 
 To evaluate how initial orientation, rate of change in orientation, and duration of post-traumatic amnesia (PTA) during inpatient rehabilitation predict cognitive functioning (overall cognition, episodic verbal memory, and executive function) 1 year and 2 years after sustaining a moderate-to-severe traumatic brain injury (TBI).
 
 
 
 Participants were 101 adults aged 18–81 years (M age = 39 years; 67% male) receiving inpatient rehabilitation following new-onset moderate–severe TBI at a level I trauma center, acute inpatient hospital. Orientation data (initial orientation, rate of change in orientation, and duration of PTA) were collected during inpatient rehabilitation where each participant received serial assessments of their orientation with the Orientation Log (O-Log) during bedside rounds. The Brief Test of Adult Cognition by Telephone (BTACT) was administered to participants over the telephone at 1 year and 2 years post-injury to assess cognitive outcomes.
 
 
 
 Initial orientation during acute inpatient rehabilitation was significantly associated with overall cognition (p < .01), episodic verbal memory (p < .01), and executive function abilities (p < .01) at 1 year post-injury. Duration of PTA and rate of change in orientation were not significant predictors, and none of the orientation factors predicted cognition at 2 years post-injury.
 
 
 
 Initial level of orientation is important to consider in the prediction of cognitive impairments one year following moderate–severe TBI. This supports the need to assess orientation early in the recovery process, particularly upon admission to acute rehabilitation.
