Abstract
OBJECTIVE: Overtreatment of asymptomatic bacteriuria (ASB) is a major cause of antibiotic overuse. We facilitated a nationwide implementation of an ASB antimicrobial stewardship intervention in 41 Veterans Affairs facilities. Twenty-one sites participated in a Virtual Learning Collaborative (VLC) with monthly webinars. We assess what VLC teams learned from one another in these webinars. METHODS: The bi-monthly VLC webinars featured expert presentations and spotlighted 1-2 site teams, asking them to discuss their barriers and facilitators for the intervention. Data come from analyses of descriptive field notes from the webinars and chat transcripts. Field notes were analyzed using the "sort and sift, think and shift" method. We sorted and labeled common strategies thematically, sifted through illustrative quotes, and iteratively discussed the results to reach consensus. RESULTS: Across 22 webinars (August 2023-April 2024), sites discussed different resources, team membership, and organizational structures. Sites had to "tailor swiftly" to their site needs and target audiences by adapting educational materials for timing, length, audience, and outreach location. Sites used five tailoring strategies to implement the antimicrobial stewardship program: Organizational and Structural Strategies, Recruitment Strategies, Data- and Information-Based Strategies, Interpersonal Strategies, and Resource Provision. CONCLUSION: VLC webinars allowed sites to share tips and strategies for the implementation of a nationwide antimicrobial stewardship program wherein rapid tailoring and local adaptations were effective. Our supportive approach to tailoring allowed implementation sites to adapt antimicrobial stewardship materials and intervention delivery to their different resources and organizational contexts.
