ABSTRACT
The aim of this study is to identify key usability requirements in telemedical services; in particular, services specialized on emergencies. To generate an optimal usercentered workflow, the communicative and organizational structure of an exemplary system was analyzed. We focused on the impact of new technologies, which are introduced to the medical workflow. The graying of societies implicates two 1najor consequences in this context: An increasing number of older people needing medical care and a shortage of medical staff in the next generation reveal a threatening supply gap concerning the security of people's health. To bridge this gap, it is necessary to develop alternative systems, which can guarantee an area-wide supply of emergency medical services, especially in rural regions with an insufficient infrastructure. Results show a high potential of telemedical emergency care, though the benefit critically depends on the given system's usability and the appropriateness of the workflow. On this basis, we introduce first guidelines, in both, communicative and ergonomic criteria, which should be carefully followed by medical practitioners, and designers, likewise.
