One Health Systems Assessment for Priority Zoonoses (OH-SAPZ)

The One Health Systems Assessment for Priority Zoonoses (OH-SAPZ) tool is a published methodology for assessing national and sub-national systems for communication and coordination between sectors for the prevention and control of priority zoonotic diseases. Piloted in Jordan and Egypt in 2013-2014, the team has since worked with the governments of Algeria, Iraq, and Guinea to implement the method and assist with One Health capacity building, in line with the International Health Regulations (2005) and Joint External Evaluation process. The methodology combines a collaborative, consensus-driven zoonotic disease prioritization step, involving relevant government ministries and potentially other pertinent partners, with a systems “mapping” that uses the identified priority zoonotic diseases as case studies to explore the existing linkages and gaps in coordination between human, animal, and environmental health at all levels of the health systems (see schematic below). The case study approach allows for a robust and detailed evaluation, grounded in real-life examples, of the processes supporting disease prevention, surveillance, diagnosis, case management, and response between and within sectors. Where possible, the methodology can also incorporate field site visits, table-top exercises, and other mechanisms to further explore systems capabilities and identify existing best practices as well as opportunities for additional capacity strengthening. 

A User Manual for the OH-SAPZ methodology is available for download below. Template facilitator guides, PowerPoint decks, and scenarios for discussion are available on request; please contact Dr. Erin Sorrell and/or Dr. Claire Standley for more information.
