Synergising tools for capacity assessment and One Health operationalisation

Multisectoral, One Health collaboration is essential for addressing national and international health threats that arise at the human-animal-environment interface. Thanks to the efforts of multiple organisations, countries now have an array of One Health tools available to assess capacities within and between sectors, plan and prioritise activities, and strengthen multisectoral, One Health coordination, communication, and collaboration. By doing so, they are able to address health threats at the human-animal-environment interface, including emerging zoonotic and infectious diseases, more efficiently. However, to ensure optimal outcomes for the countries using these One Health tools, the partners responsible for implementation should regularly collaborate and share information such as implementation timelines, results and lessons learned, so that one process can inform the next. This paper presents a consensus framework on how commonly implemented One Health tools might align to best support countries in strengthening One Health systems. Twelve One Health tools were selected based on their high implementation rates, authors' experience with these tools and their focus on multisectoral, One Health coordination. Through a four-step process, the authors: a) jointly carried out a landscape analysis of One Health tools, using a Cloudbased spreadsheet to share the unique characteristics and applications of each tool; b) performed an implementation analysis to identify and share implementation dynamics and identify respective outcomes and synergies; c) jointly created a consensus conceptual model of how the authors suggest the tools might logically work together; and d) extrapolated from steps 1-3 an agreed-upon overarching conceptual framework for how current and future One Health tools could be categorised to best support One Health system strengthening at the national level. Highlighted One Health tools include the States Parties Annual Reporting Tool under the International Health Regulations (IHR), the World Organisation for Animal Health Performance of Veterinary Services (PVS) Pathway, the Joint External Evaluation process, IHR/PVS National Bridging Workshops, the Centers for Disease Control and Prevention One Health Zoonotic Disease Prioritization Tool, the Food and Agriculture Organization (FAO) Laboratory Mapping Tool, the FAO Assessment Tool for Laboratories and Antimicrobial Resistance Surveillance Systems, the FAO Surveillance Evaluation Tool, the One Health Systems Mapping and Analysis Resource Toolkit, the National Action Plan for Health Security, and IHR Monitoring and Evaluation Framework tools for After Action Reviews and Simulation Exercises. A new guidance document entitled, Taking a Multisectoral, One Health Approach: A Tripartite Guide to Addressing Zoonotic Diseases in Countries was also included as a framework that provides guidance to support the implementation of the outputs of the tools described.
