Abstract
To the Editor-Clostridioides difficile infection (CDI) is the most common healthcare-associated infection in the United States. 1 CDI affects 13 in every 1,000 patients, and ~75% of cases are classified as hospital onset. Antimicrobial stewardship and compliance with hand hygiene and personal protective equipment (PPE) protocols are paramount in efforts to reduce horizontal CDI transmission. 2 As an epicenter of the coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), New York City hospitals saw a dramatic increase in admissions and ICU utilization. To understand the impact of COVID-19 on hospital-onset CDI, we examined antibiotic prescribing patterns, standardized infection ratios (SIRs), and baseline variables in hospitalized adult patients prior to and during the COVID-19 pandemic. We hypothesized that increased antibiotics exposure during the COVID-19 pandemic would lead to a higher incidence of CDI in hospitalized patients.
