Comparison of the O-Log and GOAT as measures of posttraumatic amnesia

Primary 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. Research design: Retrospective study. Methods and procedures: 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. Main outcomes and 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.
