Utilizing User-Centered EHR Design for Systematic Deep Brain Stimulation Data Collection.

This project aims to assess usability and acceptance of a customized Epic-based flowsheet designed to streamline the complex workflows associated with care of patients with implanted Deep Brain Stimulators (DBS). DBS patient care workflows are markedly fragmented, requiring providers to switch between multiple disparate systems. This is the first attempt to systematically evaluate usability of a unified solution built as a flowsheet in Epic. Iterative development processes were applied, collecting formal feedback throughout. Evaluation consisted of cognitive walkthroughs, heuristic analysis, and 'think-aloud' technique. Participants completed 3 tasks and multiple questionnaires with Likert-like questions and long-form written feedback. Results demonstrate that the strengths of the flowsheet are its consistency, mapping, and affordance. System Usability Scale scores place this first version of the flowsheet above the 70th percentile with an 'above average' usability rating. Most importantly, a copious amount of actionable feedback was captured to inform the next iteration of this build.
