Assessment of Innovative Emergency Department Information Displays in a Clinical Simulation Center

Abstract

The objective of this work was to assess the functional utility of new display concepts for an emergency department information system created using cognitive systems engineering methods, by comparing them to similar displays currently in use. The display concepts were compared to standard displays in a clinical simulation study during which nurse-physician teams performed simulated emergency department tasks. Questionnaires were used to assess the cognitive support provided by the displays, participants' level of situation awareness, and participants' workload during the simulated tasks. Participants rated the new displays significantly higher than the control displays in terms of cognitive support. There was no significant difference in workload scores between the display conditions. There was no main effect of display type on situation awareness, but there was a significant interaction; participants using the new displays showed improved situation awareness from the middle to the end of the session. This study demonstrates that cognitive systems engineering methods can be used to create innovative displays that better support emergency medicine tasks, without increasing workload, compared to more standard displays. These methods provide a means to develop emergency department information systems-and more broadly, health information technology-that better support the cognitive needs of healthcare providers.

Usability evaluation of an emergency department information system prototype designed using cognitive systems engineering techniques

“…Also, as part of our larger research project, we collected additional measures regarding use of these displays, in separate studies. In particular, as reported in McGeorge et al (2015), we compared these displays to control displays which mimicked current systems being used by participants in a dynamic experimental task performed by two-person participant teams (a physician and nurse) in a clinical simulation environment (McGeorge et al, 2015). Objective measures of situation awareness (collected through the SAGAT technique) along with subjective workload measures and rating of cognitive support were collected.…”

Identifying nurse managers' essential information needs in daily unit operation in perioperative settings

“…One strength was that this study was done with participants who are experts and familiar in the management of perioperative settings. Developing a new information system to support daily unit operation should be done together with those who are the possible users (Gutenstein et al, ; McGeorge et al, ). Therefore, the participants were familiar with the topic and the content of the survey was not sensitive.…”

“…Studies concerning information processes suggest focusing more on knowledge management and knowledge use studies in addition to focusing on data science. It is recommended that research is done together with end‐users (Gutenstein et al, ; McGeorge et al, ).…”

Design and Evaluation of an Integrated, Patient-Focused Electronic Health Record Display for Emergency Medicine

“…21 Previous work of this research team used methods from cognitive systems engineering to design a suite of patient tracking and ED management-related displays and evaluated those displays in laboratory and clinical simulation settings. [22][23][24] There has not, however, been a focus on designing an integrated, patient-focused view that helps clinicians on the ED care team develop, communicate about, and maintain awareness regarding a patient's health status and progress through the plan of care.…”
