OBJECTIVE: To examine the relative contributions of preinjury, injury severity,
and acute postinjury variables in predicting outcomes at 1 year following
moderate-severe traumatic brain injury (TBI). DESIGN: Secondary analysis of a
prospective longitudinal cohort study. SETTING: Four Veterans Affairs Medical
Center acute inpatient rehabilitation programs. PARTICIPANTS: Active duty
military or veterans with a nonpenetrating moderate-to-severe TBI. MAIN OUTCOME
MEASURES: Independent living status (N = 280) and work status (N = 248) at one
year postinjury. RESULTS: Preinjury characteristics as a group accounted for the
largest amount of variance in independent living status at 1 year; however,
posttraumatic amnesia (PTA) uniquely explained the largest amount of variance
(8.8%). Those with less than 60 days PTA were 9 times more likely to be
independent; those with less than 30 days PTA were 3 times more likely to be
independent. In contrast, acute postinjury characteristics accounted for the
largest amount of variance in work status, with time to rehabilitation explaining
the most unique variance (10.4%). Those with less than 48 days time to
rehabilitation were 2.4 times more likely to be productive. CONCLUSIONS: This
study highlights the differential contribution of variables in the prediction of
2 specific functional outcomes in a military sample, adding to our current body
of knowledge to assist clinicians, patients and their families following TBI.
