2042. Impact of the COVID-19 Pandemic on Healthcare-Associated Infections (HAI) by Race and Ethnicity in a Large Network of Community Hospitals: A Call to Action

Abstract

Abstract Background Inequities in healthcare among racial and ethnic minorities are globally recognized. The focus has centered on access to healthcare, equitable treatment, and optimizing outcomes. However, there has been relatively little investigation into potential racial and ethnic disparities in HAI. Methods We performed a retrospective cohort analysis of select HAI prospectively-collected by a network of community hospitals in the southeastern US, including central line-associated bloodstream infection (CLABSI), catheter-associated urinary tract infection (CAUTI), and laboratory-identified Clostridioides difficile infection (CDI). Outcomes were stratified by race/ethnicity as captured in the electronic medical record. We defined the pre-pandemic period from 1/1/2019 to 2/29/2020 and the pandemic period from 3/1/2020 to 6/30/2021. Outcomes were reported by race/ethnicity as a proportion of the total events. Relative rates were compared using Poisson regression. Results Overall, relatively few facilities consistently collect race/ethnicity information in surveillance databases within this hospital network (< 40%). Among 21 reporting hospitals, a greater proportion of CLABSI occurred in Black patients relative to White patients in both study periods (pre-pandemic, 49% vs 38%; during pandemic, 47% vs 31%; respectively, Figure 1a), while a higher proportion of CAUTI and CDI occurred in White patients (Figures 1b-c). Black patients had a 30% higher likelihood of CLABSI than White patients in the pre-COVID period (RR, 1.30; 95% CI, 0.83-2.05), which was not statistically significant (Table 1). However, this risk significantly increased to 51% after the start of the pandemic (RR, 1.51; 95% CI, 1.02-2.24). Similar trends were not observed in other HAI (Tables 2-3). Conclusion We found differences in HAI rates by race/ethnicity in a network of community hospitals. Black patients had higher likelihood of CLABSI, and this likelihood increased during the pandemic. Patient safety events, including HAI, may differ across racial and ethnic groups and negatively impact health outcomes. Disclosures Sonali D.
