OBJECTIVE: To determine the accuracy of self-reported length of coma and
posttraumatic amnesia (PTA) in persons with medically verified traumatic brain
injury (TBI) and to investigate factors that affect self-report of length of coma
and PTA duration. DESIGN: Prospective cohort study. SETTING: Specialized
rehabilitation center with inpatient and outpatient programs. PARTICIPANTS:
Persons (N=242) with medically verified TBI who were identified from a registry
of persons who had previously participated in TBI-related research. INTERVENTION:
Not applicable. MAIN OUTCOME MEASURES: Self-reported length of coma and
self-reported PTA duration. RESULTS: Review of medical records revealed that the
mean medically documented length of coma and PTA duration was 6.9+/-12 and
19.2+/-22 days, respectively, and the mean self-reported length of coma and PTA
duration was 16.7+/-22 and 106+/-194 days, respectively. The average discrepancy
between self-report and medical record for length of coma and PTA duration was
8.2+/-21 and 64+/-176 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. CONCLUSIONS: In this investigation, persons 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. Caution should be exercised when considering self-report of
length of coma and PTA duration.
