One key to addressing usability problems is to employ user testing and user-centered design.<\/jats:p><jats:p>To understand if redesigning an EHR-based navigation tool with clinician input improved user performance and satisfaction.<\/jats:p><jats:p>A usability evaluation was conducted to compare two versions of a redesigned ambulatory navigator. Participants completed tasks for five patient cases using the navigators, while employing a think-aloud protocol. The tasks were based on Meaningful Use (MU) requirements.<\/jats:p><jats:p>The version of navigator did not affect perceived workload, and time to complete tasks was longer in the redesigned navigator. A relatively small portion of navigator content was used to complete the MU-related tasks, though navigation patterns were highly variable across participants for both navigators. Preferences for EHR navigation structures appeared to be individualized.<\/jats:p><jats:p>This study demonstrates the importance of EHR usability assessments to evaluate group and individual performance of different interfaces and preferences for each design.<\/jats:p><jats:p>Citation: Hultman G, Marquard J, Arsoniadis E, Mink P, Rizvi R, Ramer T, Khairat S, Fickau K, Melton GB.
