“…We included the question regarding this objective because the need to support individual task prioritization for providers and nurses was identified through the CSE analysis process. However, we did not design a display specifically to support this objective, because that objective was focused on the individual provider, rather than the ED as a whole (Guarrera et al, 2012). This is likely why the rating for this objective was lower than for other objectives.…”

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.

“…• represent patients as they moved through phases of care from triage to disposition both individually, and across all patients; • support quick assessment and comparison of waiting room patients; • support identification of bottlenecks in care (such as unusual waits for testing or delays in reassessing patients); and • support balancing workload across care providers.

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.

“…As reported in Guarrera et al, 2012 a cognitive systems engineering model -an abstraction hierarchy model of the ED work domain -was developed based on interviews of 15 ED personnel, four attending physicians, two resident physicians, four nurses, two technicians, and three clerical staff. The abstraction hierarchy illustrated higher-level goals of the ED as well as processes, constraints, and physical resources, and was used to identify system components and related information needs (Vicente, 1999).…”

This paper presents the results of a usability evaluation conducted of an electronic Emergency Department information system (EDIS) prototype that was designed using a cognitive system engineering (CSE) approach. Participants were asked to complete tasks using the EDIS prototype, while thinking aloud about their interactions with the displays. Participants also completed subjective assessments of the system that related to 1) cognitive performance support objectives, 2) usability, usefulness, and frequency of system use, and 3) qualitative feedback. Mean scores were calculated for cognitive performance support objectives as well as usability, usefulness, and frequency of use for each display. Mean scores for all cognitive performance support objectives were six or higher. The mean usability score was five or higher, and the mean usefulness score was six or higher. Displays that provided information on individual patient status had the highest scores. Results from this evaluation regarding positive ratings for the cognitive support objectives provide evidence that CSE design methods can be used to understand the goals and objectives of medical work domains.
