OBJECTIVE: The aim of this study was to determine how the COVID-19 pandemic affected patient demographics, injury mechanisms, interhospital transfers and mortality of patients with traumatic brain injuries (TBIs) treated in US emergency departments (EDs).
DESIGN: This cross-sectional study analysed 2016-2020 Nationwide Emergency Department Sample (NEDS) data.
SETTING: US EDs contained in the NEDS.
PARTICIPANTS: Participants were patients with moderate and severe TBI who visited the ED.
PRIMARY AND SECONDARY OUTCOME MEASURES: Probability sampling design and survey weights generated nationally representative estimates of ED visits by patient demographics, hospital characteristics and COVID-19 diagnosis and the top four leading TBI causes. To assess COVID-19 impact, we calculated the per cent change of estimated TBI ED visits and disposition outcomes from 2016 to 2019 and 2019 to 2020, and proportion and 95% CI of injury severity groups and admitted/transfer by hospital type and trauma centre level. A multivariable logistic regression model identified the mortality OR by patient demographics, injury severity, hospital characteristics and COVID-19 positive diagnosis.
RESULTS: In 2020, there were 527 123 ED visits nationally for TBI, 4.3% higher than 2016 but 1.0% lower than 2019. Patients with TBI transferring to short-term hospitals and other facilities increased by 16.0% and 18.2%, respectively, from 2016 to 2019 and were 3.7% and 14.1% higher in 2020 than in 2019. An estimated 3317 patients with TBI died (in ED or later in hospital) in 2020, which is 9.8% higher than 2019. Firearm-related TBI proportion was 15.1% higher in 2020 than in 2019. Patients with TBI with injury severity scores 25-75 were significantly higher at nontrauma (29.4% vs 31.9 %) and level III trauma centres (34.9% vs 38.2%) in 2020 than in 2019. Patients with TBI treated at rural hospitals had significantly higher odds of mortality (OR=1.95, CI=1.58-2.40) than those at urban hospitals.
CONCLUSIONS: TBI patient mortality was higher at all US hospital types and almost all trauma centre levels in 2020 than in 2019. Patients with TBI treated at rural hospitals had a significantly higher mortality risk.
