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.

Auto-injection devices must be easy and intuitive to use, especially in emergency situations. However, there are many reports of safety-related issues affecting auto-injectors and pen injectors, due to usability deficits. To minimize this type of problem, the identification of potential use errors is an important and critical task in usability engineering. The aim of this systematic, qualitative literature review was to identify and catalog use errors related to disposable auto-injection devices. The key terms "auto-injector", "usability", and "safety/errors" were used to search in the PubMed and Scopus databases for articles from peer-reviewed journals and conference proceedings published in English or French between 2000 and 2017. Use errors, close calls, and operational difficulties were identified, extracted and hierarchically classified. The analysis showed that of the 1415 initially identified publications, 38 met all the eligibility criteria. A qualitative analysis identified 232 instances of use errors and close calls, which were classified into 10 main categories and then 39 subcategories. The present results could be used to guide the design, evaluation and risk analyses of disposable autoinjection devices. Our approach is in line with the European Union's latest regulations on improving the safety of medical devices-especially those concerning transparency and traceability.

DOI: 10.12685/027.7-1-3-39Aus Anwendersicht sind für die Qualität bibliothekarischer Online-Angebote zwei Aspekte entscheidend. Einerseits müssen für sie relevante Inhalte zur Verfügung stehen. Andererseits sollte es mög­lichst einfach und intuitiv möglich sein, diese Inhalte zu finden und auf sie zuzugreifen. Die Themen Usefulness und Usability sind daher für Bibliotheken von grosser Bedeutung. Der Beitrag beschreibt wie diese beiden Aspekte evaluiert werden können und wie Bibliotheken anhand von BibEval und PECI selb­ständig ihre Angebote überprüfen können.From the users’ point of view two aspects are essential for the quality of library online services. On the one hand, relevant content must be available. On the other hand, it should be simple and intuitive to find and to access this content. Therefore, the topics usability and usefulness are of great importance for li­braries. This article describes how these two aspects can be evaluated and how libraries can use BibEval and PECI for assessments of their own services.
