The overall aim of this study is to create development proposals for further development of the web-based learning tool Web Based Simulation of Patients (Web-SP). The tool is used in health care programs where students with digital help can link theoretical knowledge and practical actions to reach as close as possible to a true patient case. This study investigates whether the tool can be developed to apply to students in emergency and ambulance care. Hence, the study focus prehospital context and also solutions for a smoother use of the tool in line with user experience goals. Through contextual inquiry, interviews and focus group interviews, the development proposals have been reformed iteratively to better respond to new goals. The empirical results shows that parallel work is central to a prehospital patient case and how information architecture, navigation and structure should be reworked to better suit these conditions.
