Transition vers la mobilité dans le monde médical : n'oubliez pas l'utilisabilité

There is an increasing pressure from caregivers to get ubiquitous access to clinical information. The use of ultra-mobile devices, such as smartphone, is getting increasingly high. However, there is a need for in-depth thinking regarding the best strategy to realize this transition. Too often, IT teams go for the most straightforward solution and may think that presenting the existing interfaces on the new devices will be an efficient solution. Unfortunately, this transition is not that simple. The tactile interaction paradigm makes the usability strongly dependant of the way Articles courts des 15es Journées francophones d’informatique médicale, JFIM 2014, pages 211–218 Fès, Maroc, 12–13 juin 2014 information is presented. In this article, we are looking at demonstrating this dependence through the results from a large study testing user performances when recording simple values through different interfaces on mobile devices. Users had to enter some vital signs measure through three different interfaces. The results showed clearly that the chosen solution influences significantly user performances as well as satisfaction. This is a clear message to the stakeholders that should clearly get aware of these issues before implementing mobile solutions.
