Over a period of two weeks, full-scale simulations of a complete ICT-supported emergency prehospital stroke medical care chain were conducted for the first time, as part of the PrehospIT-Stroke project. Teams from various ambulance services tested use of the ICT support during the entire process and all stages were registered. The project aims to show the benefits of interacting ICT processes in a totally new way, but it also enables the study of the effect on work procedures and the interaction between the patient and other players in the healthcare chain. The results will be made available to the entire industry.
