Background
The growing challenge of antimicrobial resistance (AMR) is increasingly understood to be driven by multiple factors including the misuse of antimicrobial products and environmental pollution. However, targeted AMR action in health facilities focuses primarily on antimicrobial stewardship, with limited or no consideration for environmental drivers limiting programme impact. This article seeks to describe how health facilities can expand action against AMR through collaborative One Health approaches, building on the World Health Organization (WHO) core components for infection prevention and control (IPC).
Methods
A rapid review was conducted on the integration of environmental sustainability, IPC and antimicrobial stewardship across six databases for articles published globally, along with a review of publicly available contemporary guidance documents linked to IPC and environmental sustainability. Current IPC and sustainability practices were then compared with opportunities for sustainability identified across the WHO core components for IPC. Finally, a theorized causal pathway for the implementation of this strategy was developed.
Results
Despite increased calls for health facilities to embrace a One Health approach to AMR, there is limited evidence in the literature for how to achieve this. However, significant overlap exists between IPC and sustainability objectives. As such, the authors propose: (i) a theorized causal pathway; and (ii) a strategy to integrate environmental sustainability systematically across the eight WHO core components for IPC.
Conclusion
Action against AMR can be accelerated if hospital IPC and sustainability programmes adopt One Health approaches. A framework for this is proposed using the WHO core components for IPC given their widespread use.
