OBJECTIVE: To investigate whether any specific acute care surgery patient populations are associated with a higher incidence of COVID-19 infection. BACKGROUND: Acute care providers may be exposed to an increased risk of contracting the COVID-19 infection since many patients present to the emergency department without complete screening measures. However, it is not known which patients present with the highest incidence. METHODS: All acute care surgery (ACS) patients who presented to our level I trauma center between March 19, 2020, and September 20, 2020 and were tested for COVID-19 were included in the study. The patients were divided into two cohorts: COVID positive (+) and COVID negative (-). Patient demographics, type of consultation (emergency general surgery consults [EGS], interpersonal violence trauma consults [IPV], and non-interpersonal violence trauma consults [NIPV]), clinical data and outcomes were analyzed. Univariate and multivariate analyses were used to compare differences between the groups. RESULTS: In total, 2177 patients met inclusion criteria. Of these, 116 were COVID+ (5.3%) and 2061 were COVID- (94.7%). COVID+ patients were more frequently Latinos (64.7% vs 61.7%, p=0.043) and African Americans (18.1% vs 11.2%, p<0.001) and less frequently Caucasian (6.0% vs 14.1%, p<0.001). Asian/Filipino/Pacific Islander (7.8% vs 7.2%, p=0.059) and Native American/Other/Unknown (3.4% vs 5.8%, p=0.078) groups showed no statistical difference in COVID incidence. Mortality, hospital and ICU lengths of stay were similar between the groups and across patient populations stratified by the type of consultation. Logistic regression demonstrated higher odds of COVID+ infection amongst IPV patients (OR 2.33, 95% CI 1.62-7.56, p<0.001) compared to other ACS consultation types. CONCLUSION: Our findings demonstrate that victims of interpersonal violence were more likely positive for COVID-19, while in hospital outcomes were similar between COVID-19 positive and negative patients.
