title: Comparison of the O-Log and GOAT as measures of posttraumatic amnesia.
abstract: OBJECTIVE
  To compare PTA severity and duration assessments made by Orientation Log (O-Log) and the Galveston Orientation and Amnesia Test (GOAT) and the relationship of data yielded by these assessments to rehabilitation outcomes.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  O-Log, GOAT, demographic, length of stay, and Functional Independence Measure (FIM) data among 83 inpatient subjects with recent TBI requiring inpatient care were reviewed.
  
  
  RESULTS
  PTA severity and duration as assessed by the O-Log and the GOAT are statistically similar and correlate similarly with rehabilitation LOS and discharge total FIM score. Simple linear regression models suggest that O-Log scores better predict rehabilitation outcomes than GOAT scores.
  
  
  CONCLUSIONS
  Although the O-Log and GOAT perform similarly as measures of PTA severity and duration, PTA assessments using the O-Log offers better prediction of rehabilitation outcomes. Further study of the O-Log as an alternate assessment of PTA is warranted.
