Interoperable medical device GUI for SDC Workstations

Abstract

This paper investigates whether, within the framework of interconnected medical devices, a graphical user interface (GUI) that is developed based on standardized, machine-readable user-interface requirements (UI Profiles) can achieve the same level of usability and safety as commercially available High Frequency (HF) devices. The results of this study demonstrate that a GUI generated from a standardized UI Profile can be as safe and usable as established solutions on the market. The UI Profile-based GUI and two commercially available solutions (BOWA ARC 400, ERBE VIO® 3) were evaluated in a formative usability study by 17 clinicians at the University Hospital Aachen and University Hospital Essen, Germany. The task completion times and rates, user satisfaction, and learnability have been measured and evaluated. The UI Profile-based GUI performed well for all tasks and achieved similar performance levels compared to the established solutions. UI Profiles could provide a practical complement to medical device interoperability standards (IEEE 11073 SDC), enabling the exchange of usability-related data and commonly agreed device (type) specific human-machine-interface requirements.
