Public communication about antimicrobial resistance (AMR) is widely acknowledged as a cornerstone of global, national, and regional strategies to tackle this urgent health threat. However, much like AMR itself, efforts to communicate about it are hindered by complex and intersecting challenges. This scoping review synthesises insights from 88 scholarly manuscripts published between 2015 and 2024 to explore critical issues in AMR communication and identify potential options to address them. We distil nine overarching themes that underpin effective public communication and engagement, with particular significance for engaging with disadvantaged and vulnerable communities. These themes encompass (1) social science theoretical frameworks, (2) varied sociocultural contexts, (3) public engagement and dialogue, (4) linguistic considerations, (5) messaging strategies, (6) media use and its impacts, (7) large-scale public campaigns, (8) creative communication approaches, and (9) evaluation. We discuss each theme and outline related recommendations, collectively advocating a re-imagining of AMR communication as a civic, cultural, and reflexive practice that is attuned to the complexities of diverse contexts and cultures, and designed to enhance societal relevance and impact.
