Name of journal: Applied ergonomicsAbstract: Copyright © 2016 Elsevier Ltd. All rights reserved.This article presents an evaluation of novel display concepts for an emergency department information system (EDIS) designed using cognitive systems engineering methods. EDISs assist emergency medicine staff with tracking patient care and ED resource allocation. Participants performed patient planning and orientation tasks using the EDIS displays and rated the display's ability to support various cognitive performance objectives along with the usability, usefulness, and predicted frequency of use for 18 system components. Mean ratings were positive for cognitive performance support objectives, usability, usefulness, and frequency of use, demonstrating the successful application of design methods to create useful and usable EDIS concepts that provide cognitive support for emergency medicine staff. Nurse and provider roles had significantly different perceptions of the usability and usefulness of certain EDIS components, suggesting that they have different information needs while working.All authors: Benda NC, Bisantz AM, Clark LN, Fairbanks RJ, Guarrera-Schick TK, Hegde S, Hettinger AZ, LaVergne DT, McGeorge NM, Perry SJ, Wears RLFiscal year: FY2017Digital Object Identifier: Date added to catalog: 2017-03-09
