The Israeli emergency medical service (EMS), is a pre-hospital medical care provider that needs to be prepared for every scenario from routine emergency calls to terror attacks and regional wars. In those complex multi-casualty incidents (MCIs), medical work is characterized by working in distributed teams involving roles such as dispatch supervisor, commander at the scene and many paramedics, who all work together remotely as a distributed team in order to provide effective response and care. Transactive memory (TMS) is a construct that explains how groups process and share knowledge in order to achieve their collective goals. As distributed teams have constraints on face-to-face communication, team displays are a popular technological solution for supporting teamwork. The goal of the current project was to design and develop a team display based on TMS theory principles to assist distributed EMS teams in managing multi-casualty events. For that aim, an extensive user research consisting of interviews, observations and reviews of formal documentation was conducted. A conceptual and detailed design of the team display was created based on the user research and on transactive memory theory principles that were applied in the design process. Finally, the team display was developed and a small-scale investigation was performed in order to evaluate the effect of the display on team performance and transactive memory development. Several two-person teams participated in a simulation of a multi-casualty event management task with the display and without it. The results provide a preliminary support that using a team display can improve task performance and transactive memory compared to verbal communication only. The results are discussed in terms of their theoretical value for developing and maintaining transactive memory in computer-mediated environments as well as their practical significance in creating a functional simulator for MCI management that can be used both for training EMS personnel and as a platform for future empiric research.
