Abstract
BACKGROUND The 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 OBJECTIVE The 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 METHODS Nurses 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 RESULTS A 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 CONCLUSIONS Besides 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
