Introduction

Traumatic brain injury (TBI) poses a significant public health challenge with profound impacts at individual, family, community, and societal levels. Early during the COVID-19 pandemic, the neighborhood of Elmhurst, Queens in New York City was a hotspot dubbed the “epicenter of the epicenter” of the crisis in the United States, requiring major changes in healthcare resource allocation. This study investigates how different phases of the COVID-19 pandemic affected the incidence, severity, and clinical outcomes of TBI in this geographical area.

Methods

TBI admissions to NYC Health + Hospitals/Elmhurst, a Level 1 Trauma Center, during the first six months of 2019, 2020, and 2021 were retrospectively analyzed. Data were grouped into three periods: pre-pandemic (1/1/19–6/30/19 and 1/1/20–2/29/20) [Group 1], first COVID-19 wave (3/1/20–6/30/20) [Group 2], and second COVID-19 wave (1/1/21–6/30/21) [Group 3]. Univariate analyses were conducted to explore factors potentially associated with TBI outcomes; variables that reached statistical significance (p < 0.05) were included in a binary logistic regression analysis dichotomized into good outcome (discharge to home or acute rehabilitation disposition) and poor outcome (discharge to skilled nursing facility/subacute rehabilitation, hospice, or in-hospital mortality).

Results

Analysis of 443 TBI patients (median age 56 [range 38, 73]; mean admissions/week 5.6 ± 2.7) demonstrated no significant variance in age (H = 0.92; p = 0.63), sex (χ2 = 1.4, p = 0.51), or ethnicity (χ2 = 17.1; p = 0.07) across groups. Group 2 had significantly fewer weekly admissions (3.9 ± 2.6) compared to Groups 1 (5.9 ± 2.2; p = 0.02) and 3 (6.1 ± 2.9; p = 0.01). Over the course of the pandemic, the proportion of uninsured patients decreased from 15 to 4%, while Medicaid and Medicare coverage rates rose from 25 to 41% and 20% to 28%, respectively (p < 0.001). A binary logistic regression model dichotomized by discharge outcome for all 443 TBI patients confirmed that increasing age (OR = 0.95; 95% CI 0.93–0.97; p < 0.001) and Injury Severity Score (OR = 0.88; 95% CI 0.83–0.93; p < 0.001) were inversely correlated with good outcome, while higher Glasgow Coma Scale (OR = 1.26; 95% CI 1.17–1.36; p < 0.001) was positively correlated. Of particular interest, Black/Hispanic ethnicity (OR = 0.36; 95% CI 0.19–0.66; p = 0.002) and public health insurance (Medicaid/Medicare) coverage (OR = 0.83; 95% CI 0.68–1.00; p = 0.05) were both associated with less favorable outcomes. Neither group designation, patient sex, COVID-19 status, or need for neurosurgical intervention was correlated with outcome (p > 0.05).

Conclusion

Despite the changes in TBI admission patterns throughout New York City during the COVID-19 pandemic, the quality of patient outcomes at our institution remained relatively consistent across the pandemic’s different phases, as assessed by discharge disposition. However, two important socioeconomic factors—ethnicity and health insurance status—were significantly associated with outcome, underscoring the need for systemic changes to address ongoing disparities in neurotrauma care.
