Abstract

Emergency departments collect large amounts of data to make decisions regarding patient care. Implementation of decision support tools with information visualization (IV) techniques in Emergency Department Information System (EDIS) is difficult to achieve and thus an evaluation of the techniques is needed. The purpose of this study is to conduct a usability study of various IV techniques in EDIS and provide recommendations for developers. Fifty-nine participants were recruited in this study. Results indicate the density chart, tree map, and network diagram have lower times, higher usability scores, and lower mental workload ratings than the 3D scatter plot, scatter plot matrix, and parallel coordinates. Findings of this study can provide insights for the development of information visualization tools to support decision making in an emergency department information system.
