Robert Eardley, CIO, Houston Methodist. Millions have been invested in EHRs but are they intuitive enough for physicians, nurses and others to complete their everyday tasks easily? In this teleconference, we’ll explore the science of usability. Usability science systemically observes user interactions and gives guidance on changes that can improve the System Usability Score (SUS). Robert discusses SUS, along with the implementation at Houston Methodist and lessons learned.
