Objectives:
To describe return to work (RTW) for motor vehicle accident (MVA) survivors with mild traumatic brain injury (MTBI) and to examine relationships between RTW and injury severity, cognitive impairment, social interaction, discharge disposition, and sociodemographics.
Design:
Inception cohort assessed within 1 month of injury and at follow-up 6 to 9 months (mean = 7.4) after injury, for comparisons on outcome of RTW.
Setting:
Tertiary care center in Toronto (time 1); at home for follow-up.
Participants:
Fifty patients with MTBI resulting from MVA who were consecutively admitted during a 20-month period ending April 1994. Thirteen of 63 eligible patients refused consent or were lost to follow-up. Mean age was 31; 62% were men.
Eligibility Criteria:
(1) patients had been working; (2) they had no history of head injury, neurologic disease, or psychiatric illness requiring hospitalization; and (3) they had no catastrophic impairment from accident.
Main Outcome Measure:
Return to work (at premorbid or modified level).
Results:
Of the 42% who returned to work, 12% resumed their premorbid level of employment and 30% returned to modified work. There were significant differences (p<.05) between the groups in level of social interaction, premorbid occupation, and discharge disposition. On one test of cognitive functioning the difference was at p = .06.
Conclusion:
Social interaction, jobs with greater decision-making latitude, and discharge home were positively related to RTW for this population. Cognitive impairment within the first month was not a reliable indicator of RTW potential.
