Multidisciplinary outpatient treatment in patients with mild traumatic brain injury: A randomised controlled intervention study

To evaluate the efficacy of a multidisciplinary outpatient follow-up programme compared to follow-up by a general practitioner for patients being at-risk or sick-listed with persistent post-concussion symptoms two months after a mild traumatic brain injury.

Randomised controlled trial.

One hundred fifty-one patients, 16-56 years.

Multidisciplinary outpatient rehabilitation with individual contacts and a psycho-educational group intervention at two outpatient rehabilitation clinics compared to follow-up by a general practitioner after the multidisciplinary examination. Primary outcome was sustainable return-to-work first year post-injury. Secondary outcomes were post-concussion symptoms, disability, the patient's impressions of change and psychological distress.

Days to sustainable return-to-work was 90 in the intervention and 71 in the control group (p = 0.375). The number of post-concussion symptoms were fewer in the intervention (6) compared to the control group (8) at 12 months (p = 0.041). No group differences were observed for disability (p = 0.193), patients impression of change (p = 0.285) or psychological distress (p = 0.716).

The multidisciplinary outpatient follow-up programme focusing on better understanding and reassurance of favourable outcome for mild traumatic brain injury did not improve return-to-work, but may have reduced the development of post-concussion symptoms. Additional studies should focus on which factors exhibit a direct impact on return-to-work.
