Abstract

Multi-casualty incidents (MCI) are complex and dynamic situations during which the emergency medical dispatch (EMD) manager is required to monitor and control multiple and constantly changing elements. For the current study, the EMD of Magen David Adom, under the management of the shift supervisor, was considered as a case study for MCI management. The goal of the current study was to support the shift supervisor's situation awareness (SA) and performance during MCI management, by designing and testing a predictive situation display. The display designing phase included user research and task analysis and was followed by a conceptual and detailed design of the display. In order to test the display, seventeen participants were asked to monitor four MCI scenarios. Two of the scenarios were monitored using the predictive situation display, and two were monitored using a control situation display. Each display condition included a high and low workload level scenario and the participants’ SA and performance were measured. The results show that the participants' level 3 SA, namely their ability to project the future state of elements in the environment, was higher in the predictive situation display condition in comparison to the control situation display. In addition, the participants had a higher performance rate when using the predictive situation display under a high workload condition compared to the control situation display. In general, these findings support our main hypothesis which posits that the predictive situation display will facilitate level 3 SA and performance. These findings provide initial support to the theoretical connection between predictive displays and level 3 SA. They further support the known connection between predictive displays and performance as well as elaborate the connection to the MCI management field. On a practical level, a predictive situation display was designed and tested. The new display can be implemented in MDA’s EMD and provide real time support to MCI management.
