Abstract

BACKGROUND: The COVID-19 pandemic reshaped the healthcare system in 2020. COVID-19 infection has been associated with poor outcomes after orthopedic surgery and elective, general surgery, but the impact of COVID-19 on outcomes after trauma is unknown.

METHODS: We conducted a retrospective cohort study of patients admitted to Pennsylvania trauma centers from March 21-July 31, 2020. The exposure of interest was COVID-19 (COV +) and the primary outcome was inpatient mortality. Secondary outcomes were length of stay and complications. We compared demographic and injury characteristics between positive, negative, and not-tested patients. We used multivariable regression with coarsened exact matching to estimate the impact of COV+ on outcomes.

RESULTS: Of 15,550 included patients, 8,170 (52.5%) were tested for COVID-19 and 219 (2.7%) were positive (COV+). Compared to COVID-19 negative (COV-) patients, COV+ patients were similar in terms of age and sex, but were less often white (53.5% vs. 74.7%, p < 0.0001), and more often uninsured (10.1 vs 5.6%, p = 0.002). Injury severity was similar, but firearm injuries accounted for 11.9% of COV+ patients vs. 5.1% of COV- patients (p < 0.001). Unadjusted mortality for COV+ was double that of COV- patients (9.1% vs 4.7%, p < 0.0001) and length of stay was longer (median of 5 vs. 4 days, p < 0.001). Using coarsened exact matching, COV+ patients had an increased risk of death (OR 6.05, 95% CI 2.29, 15.99), any complication (OR 1.85, 95% CI 1.08, 3.16), and pulmonary complications (OR 5.79, 95% CI 2.02, 16.54) compared to COV- patients.

CONCLUSIONS: Patients with concomitant traumatic injury and COVID-19 infection have elevated risks of morbidity and mortality. Trauma centers must incorporate an understanding of these risks into patient and family counseling and resource allocation during this pandemic.
