Predicare, a Swedish company created in 2010, has developed the RETTS© (Rapid Emergency Triage and Treatment System) tool. This tool aims to quickly identify the care and treatment that the patient will need. Building on its leading position in the Scandinavian market, Predicare has succeeded in developing a scientifically validated tool at Sahlgrenska University Hospital in Sweden and then transformed the tool into a computerized solution to make it easier to use. RETTS© can be used both in hospital emergency departments and in ambulances. The decision tree allows a color code to be assigned to the patient, corresponding to the degree of urgency of care. Today, Predicare wants to equip even more hospitals and ambulances around the world.
