Antimicrobial stewardship (AMS) programs in hospitals comprise coordinated strategies to optimise antimicrobial use. The COVID-19 pandemic had a significant impact on the healthcare system, including AMS. This study aimed to understand the work processes of AMS teams during COVID-19 hospital restrictions and the role technology played in supporting AMS. Observations and interviews were conducted with AMS teams at two hospitals in Sydney, Australia. Participants reported an increase in antimicrobial use, a loss of resources for AMS activities, and reduced in-person interactions. Meetings were performed through videoconferencing, which resulted in greater access to information but led to poorer communication and impacted interdisciplinary relationships. As COVID-19 restrictions recede, AMS program changes should be evaluated to understand the most effective strategies to facilitate evidence-based AMS practices.
