Effect of tele-COVID rounds and a tele-stewardship intervention on antibiotic use in COVID-19 patients admitted to 17 small community hospitals

Antibiotic stewardship interventions are urgently needed to reduce antibiotic overuse in hospitalized COVID-19 patients, particularly in small community hospitals (SCHs), who often lack access to infectious diseases (ID) and stewardship resources. We implemented multidisciplinary tele-COVID rounds plus tele-antibiotic stewardship surveillance in 17 SCHs to standardize COVID management and evaluate concurrent antibiotics for discontinuation. Antibiotic use was compared in the 4 months preintervention versus 10 months postintervention. Interrupted time-series analysis demonstrated an immediate decrease in antibiotic use by 339 days of therapy/1000 COVID-19 patient days (p
