Abstract:
Study examined the accuracy of self-reported length of coma and posttraumatic amnesia (PTA) in patients with medically verified traumatic brain injury (TBI) and identified factors that affect self-report of length of coma and PTA duration. A total of 242 individuals with medically verified TBI were identified from a registry of persons who had previously participated in TBI-related research. Review of medical records revealed that the mean medically documented length of coma and PTA duration was 6.9 and 19.2 days, respectively, and the mean self-reported length of coma and PTA duration was 16.7 and 106 days, respectively. The average discrepancy between self-report and medical record for length of coma and PTA duration was 8.2 and 64 days, respectively. Multivariable regression models revealed that time since injury, performance on cognitive tests, and medical record values were associated with self-reported values for both length of coma and PTA duration. In this study, people with medically verified TBI showed poor accuracy in their self-report of length of coma and PTA duration. Discrepancies were large enough to affect injury severity classification. The findings suggest that caution should be exercised when considering self-report of length of coma and PTA duration.
