This webinar, ‘A Transdisciplinary Approach to Co-developing an Infection Prevention and Control Training App for Veterinarians’, one of a series provided by the UKRI-funded PEOPLE AMR (antimicrobial resistance) Network, (develoPing and Evaluating multi-faceted evidence-based interventions to prOmote Prudent antimicrobiaL use in community contExts), describes the achievements of the AHRC-funded AMRSim (A Microbial Reality Simulator) and VIPVis (Veterinary Infection Prevention through Visualisation) studies, both led by Prof Alastair Macdonald, Senior Researcher School of Design at The Glasgow School of Art, and conducted in collaboration with the School of Veterinary Medicine at the University of Surrey. This is prefaced by a short presentation by Dr Abel Ekiri (Lecturer in Infectious Disease Epidemiology), from the School of Veterinary Medicine at the University of Surrey on the challenge of hospital acquired infections (HAIs) in human healthcare settings and in small animal practices. Macdonald describes the transdisciplinary co-development process leading to the proof of concept (AMRSIm) and the beta version app (VIPVIs) infection prevention and control (IPC) training tool for veterinary staff, using visualisation, ‘serious storytelling’, iterative prototyping, and highlighting the potential contributions that design can make in transdisciplinary studies relating to AMR, HAIs and IPC.
