Vocational outcome indicators in atypically recovering mild TBI: a post-intervention study.
Beyond issues of MTBI etiology, a key question remains the characterization and early identification of those individuals at risk of poor functional outcome. Using a retrospective analysis, the current study aimed at identifying the specific indicators related to return to work in adults with both symptomatic MTBI and functional impacts, having completed a specialized intervention program. In terms of outcome, 59.1% of the cohort (n=110) returned to some form of work-related activity by the end of intervention whereas the rest had not. Three of the sixteen variables studied were retained (logistic regression) as providing unique and significant (p<0.05) contributions to the prediction outcome model, namely age, number of subjective symptoms and the presence of a public insurance provider. There was also an interaction between the presence of a public insurance provider and referral delay. Overall percentage of cases correctly classified by the model was 70%, positive predictive accuracy was 72.9%, whereas negative predictive accuracy was 65%. Our findings suggest that any studies attempting to assess functional outcome need to take account of the multifactorial nature of MTBI, including not only more objective psychological/physiological variables related to the injury, but also subjective complaints and environmental factors.
