In their everyday work, health care professionals increasingly have to deal with people who, due to illness, are no longer able to articulate themselves well in spoken language. For professionals, communication with these people is not always easy; it takes a lot of time and can lead to misunderstandings. Within the framework of the project ProDigA - Digitally Supported Interaction Work the iso-Institut has now developed a Information brochure for professionals and managers in the health care sector. It is intended to raise awareness of communication barriers as well as provide tips for "good" interaction and therefore contribute not only to patient welfare but also to relieving the workload of staff. The project is supported by the Bundesministerium für Bildung und Forschung (BMBF) (German Federal Ministry of Education and Research (BMBF)) funded.
