AbstractBackground:Antimicrobial resistance (AMR) causes worsening health, environmental, and financial burdens. Modelling complex issues such as AMR is important, however, how well such models and data cover the broader One Health system is unknown. Our study aimed to identify models of AMR across the One Health system (objective 1), and data to parameterize such models (objective 2) to inform a future model of the AMR in the Swedish One Health system. Based on an expert-derived qualitative description of the system, an extensive literature scan was performed to identify models and data from peer-reviewed and grey literature sources. Models and data were extracted, categorized in an Excel database, and visually represented on the existing qualitative model to illustrate coverage. The articles identidied described 106 models in various parts of the One Health system; 54 were AMR-specific. Few multi-level, multi-sector models, and models within the animal and environmental sectors, were identified. We identified 414 articles containing data to parameterize the models. Data gaps included the environment and broad, ill-defined, or abstract ideas (e.g., human behaviour). In conclusion, no models addressed the entire system, and many data gaps were found. Existing models could be integrated into a mixed-methods model in the interim.
