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.
