273 A Direct Domparative Analysis of Pediatric Traumatic Brain Injury Presentation and Outcomes in the United States and Uganda

INTRODUCTION: Pediatric traumatic brain injury (pTBI) is the leading cause of death and disability among children globally. However, few studies have explored pTBI in low- and middle-income countries (LMICs) compared to high-income countries (HICs). METHODS: Patient records were extracted from the Duke University Hospital subset of the National Trauma Data Bank (NTDB, n = 866) and a dataset at the Mbarara Regional Referral Hospital in Uganda (MRRH, n = 571). Descriptive statistics were performed to compare across settings. Logistic regression was used to quantify the odds of mortality in each setting given ICU utilization, admission GCS, and other factors. RESULTS: In-hospital mortality was higher in the LMIC versus the HIC (9.4% vs 2.9%, p < 0.001), while ICU utilization was lower in the LMIC (9.0% vs 33.4%, p < 0.001). Rates of surgical management did not differ significantly (15.8% vs 17.0%). More patients presented with moderate (27.8% vs 4.3%) and severe TBI (16.5% vs 11.8%) in the LMIC (p < 0.001). No deaths were reported among patients presenting with moderate or mild TBI in the HIC setting, whereas LMIC pTBI patients died in every TBI severity category. Over 50% of LMIC ICU patients died, versus 8.1% of HIC ICU patients. In a multivariate regression model of mortality, ICU placement was associated with mortality (OR: 6.7, 95% CI: 2.1-20.9), an association not seen in the HIC setting. CONCLUSIONS: Pediatric TBI mortality is greater in the LMIC vs the HIC setting. The LMIC setting also had a high prevalence of moderate/severe TBI and low ICU availability and effectiveness. Future work should involve the implementation and evaluation of interventions to assess these gaps in the LMIC setting.
