Unexpectedly High Frequency of Enterococcal Bloodstream Infections in COVID-19 Patients
Coronavirus disease 2019 seemed to increase the frequency of bloodstream infections (particularly Enterococcus-related bloodstream infection) after ICU admission. This may have been due to enteric involvement in patients... read more
Long-Term Sustainability and Acceptance of Antimicrobial Stewardship in Intensive Care
An antimicrobial stewardship program implemented over a decade resulted in sustained suggestion and acceptance rates. These findings support the need for a persistent presence of audit-and-feedback over time with more frequent... read more
