Outpatient Follow-up After Pediatric Traumatic Brain Injury at an Urban Safety Net Hospital: A Retrospective Cohort Study.

Introduction: Traumatic brain injury (TBI) is the leading cause of pediatric disability. Most pediatric TBIs are mild but can result in long-term cognitive and functional impairments. Outpatient follow-up is essential to detect post-concussive symptoms and aid recovery.

Methods: All patients 3-18 years of age with positive TBI findings on CT or MRI from 2018-2024 were retrospectively reviewed. Follow-up was defined as an appointment with neurology, neuropsychology, neurosurgery, or physical medicine and rehabilitation within three months of discharge. Analyses were performed with appropriate Chi-squared, Fisher's exact, Mann-Whitney U, or t-tests.

Results: Fifty-seven patients (41 male, mean age 11.4 years) were identified, with mild TBIs (GCS 13-15) comprising 41/57 (71.9%). Four patients (7.0%) died from their injury. Of 53 surviving patients, 20 (37.7%) had follow-up appointments scheduled for them at discharge, seven (13.2%) were given a specific date and contact number, 17 (32.1%) received service referrals without a specific date, and eight (15.1%) received nonspecific directions or were directed only to follow-up with non-neuroscience services. Within three months, 32 (60.4%) patients followed up, though only 22/53 (41.5%) patients saw a non-surgical neuroscience discipline. Patients who followed up were more likely to have undergone neurosurgery (p = 0.007) or any surgical procedure at all (p = 0.007). They were also more likely to have a shorter hospital length of stay (p = 0.021). Discharge instruction type was significantly associated with follow-up (p = 0.0013); 62.5% of patients who followed up had an appointment scheduled for them or were given a specific date versus 33.4% of patients who did not follow-up. Conversely, 38.1% of patients without follow-up received nonspecific instructions or were told to follow-up with non-neuroscience specialties. This finding remained significant when excluding patients with severe TBI. Follow-up had no significant associations with demographics, injury severity, or insurance type.

Conclusion: Patient-centered discharge instructions with detailed service referrals increase access to critical follow-up care. Children with TBIs should have follow-up care arranged regardless of injury severity. Larger multicenter studies are needed to validate these findings.
