Abstract
BackgroundThe introduction of clinical information systems has increased the amount of clinical documentation. Although this documentation generally improves patient safety, it has become a time-consuming task for nurses, which limits their time with the patient. On the basis of a user-centered methodology, we have developed a mobile app named BEDSide Mobility to support nurses in their daily workflow and to facilitate documentation at the bedside.ObjectiveThe aim of the study was to assess the usability of the BEDSide Mobility app in terms of the navigation and interaction design through usability testing.MethodsNurses were asked to complete a scenario reflecting their daily work with patients. Their interactions with the app were captured with eye-tracking glasses and by using the think aloud protocol. After completing the tasks, participants filled out the system usability scale questionnaire. Descriptive statistics were used to summarize task completion rates and the users’ performance.ResultsA total of 10 nurses (aged 21-50) participated in the study. Overall, they were satisfied with the navigation, layout, and interaction design of the app, with the exception of one user who was unfamiliar with smartphones. The problems identified were related to the ambiguity of some icons, the navigation logic, and design inconsistency.ConclusionsBesides the usability issues identified in the app, the participants’ results do indicate good usability, high acceptance, and high satisfaction with the developed app. However, the results must be taken with caution because of the poor ecological validity of the experimental setting.

Summary
Background The introduction of clinical information system in hospitals has impacted the workflow of nurses in several ways. Studies have reported that up to 30% of daily workload was spent on documentation [6] Until recently, all this clinical documentation was performed on desktop computers, which keeps nurses away from the patient bedside [7], induces http://mhealth.jmir.org/2018/3/e57/ XSLFO RenderX. 1 (page number not for citation purposes) transcription errors [8], and creates a delay in the availability of collected data within the electronic health record (EHR) To some extent, this problem has been addressed with the use of wireless networks and computers on wheels (COWs) [9], but mobility can be further increased by the use of smartphones and mobile apps [10,11].
