Abstract

Background and aim: Clostridioides difficile infection (CDI) is the leading cause of hospital acquired-infectious diarrhea in the USA. In this study, we assess the prevalence and impact of CDI in COVID-19 hospitalizations in the USA.

Methods: We used the 2020 National Inpatient Sample database to identify adult patients with COVID-19. The patients were stratified into two groups based on the presence of CDI. The impact of CDI on outcomes such as in-hospital mortality, ICU admission, shock, acute kidney injury (AKI), and sepsis rates. Multivariate regression analysis was performed to assess the effects of CDI on outcomes.

Results: The study population comprised 1581 585 patients with COVID-19. Among these, 0.65% of people had a CDI. There was a higher incidence of mortality in patients with COVID-19 and CDI compared with patients without COVID-19 (23.25% vs 13.33%, P < 0.001). The patients with COVID-19 and CDI had a higher incidence of sepsis (7.69% vs 5%, P < 0.001), shock (23.59% vs 8.59%, P < 0.001), ICU admission (25.54% vs 12.28%, P < 0.001), and AKI (47.71% vs 28.52%, P < 0.001). On multivariate analysis, patients with CDI had a statistically significant higher risk of mortality than those without (aOR = 1.47, P < 0.001). We also noted a statistically significant higher risk of sepsis (aOR = 1.47, P < 0.001), shock (aOR = 2.7, P < 0.001), AKI (aOR = 1.55, P < 0.001), and ICU admission (aOR = 2.16, P < 0.001) in the study population.

Conclusions: Our study revealed the prevalence of CDI in COVID-19 patients was 0.65%. Although the prevalence was low, its presence is associated with worse outcomes and higher resource utilization.
