Mapping One Health studies and practices that integrate the human, animal and environmental health dimensions: A scoping review protocol

The One Health framework highlights the interconnectedness of human, animal, and environmental health, requiring interdisciplinary and multisectoral collaboration to address complex global health challenges. This scoping review will systematically map how studies and policy initiatives have incorporated socioecological interconnections within the One Health paradigm (2004 to 2025), following Joanna Briggs Institute guidance and the PRISMA Sc checklist. Searches will be conducted in PubMed, Scopus, Web of Science, LILACS, Health Systems Evidence, Social Systems Evidence, and Google Scholar. The strategy, developed with librarian support and peer reviewed, includes terms in English, Portuguese, and Spanish; pilot searches retrieved 5,333 PubMed and 470 LILACS records. Eligible documents must explicitly present two or more One Health dimensions: food safety, zoonotic diseases, antimicrobial resistance, and environmental health. Data will be extracted using a standardized tool and synthesized in narrative, tabular, and graphical formats. The review will provide a comprehensive mapping of practices and policies, identifying achievements, barriers, and knowledge gaps to inform future strategies and strengthen global health governance.
