Patterns and predictors of follow-up in patients with mild traumatic brain injury

This study was undertaken to identify factors that influence follow-up for patients with mild traumatic brain injury (MTBI).

One hundred and ninety-nine consecutive inpatients diagnosed with MTBI at a Trauma Centre (or TC) were monitored for establishment of care with a brain injury specialist after discharge. Bivariate statistics were calculated to determine subject characteristics impacting the decision to pursue TBI-related specialty care.

One hundred and nineteen patients (59.8%) followed up with the TC for routine post-injury care. Patients who followed up were older (age >40: OR = 2.48, p = 0.01, 95% CI = 1.03-8.96) and had longer hospital lengths of stay (LOS > 3 days: OR = 2.99, p < 0.001, 95% CI = 1.33-7.67). Upon follow-up, providers identified 20 patients (16.8%) with persistent neurologic symptoms, seven (3.5%) of whom saw a brain injury specialist. Lack of insurance significantly decreased the likelihood of follow-up with the TC and/or establishment of care with a TBI specialist. (OR = 0.76, p = 0.01, 95% CI = 0.62-0.95).

Being insured was strongly predictive for follow-up at the TC and for establishing with a brain injury specialist post-MTBI. The TC post-injury visit identified MTBI patients with persistent symptoms, suggesting post-acute TC follow-up is an important venue for MTBI sequelae screening and referral.
