Combined Expert and User-Driven Usability Assessment of Trauma Decision Support Systems Improves User-Centered Design.

Background: Trauma clinical decision support systems improve adherence with evidence-based practice but suffer from poor usability and the lack of a user-centered design. The objective of this study was to compare the effectiveness of user and expert-driven usability testing methods to detect usability issues in a rib fracture clinical decision support system and identify guiding principles for trauma clinical decision support systems.

Methods: A user-driven and expert-driven usability investigation was conducted using a clinical decision support system developed for patients with rib fractures.
