Clinical algorithms can divide sophisticated treatment concepts for blunt trauma care into logical, systematic and easy to follow sequences. The presented algorithm for prehospital management of major and suspected blunt trauma will assure appropriate trauma care within narrow time windows. The risk of over- or undertreatment is reduced for both, the suspected and confirmed diagnosis of polytrauma. Due to the lack of evident data the algorithm was confirmed via consent expert opinion of trauma surgeons, incorporating the ABC priorities and also the concept of the ATLS((R))-programme. The algorithm was validated in simulated scenarios and was by affirmed by the German Trauma Surgeons Task Force on Emergency Care under the regulations of a nominal group process via resolution.
