In the event of an accident it is the responsibility of the public health service to attempt to save lives, and to reduce pain and permanent disability. This is done by a complex chain of actions by persons ranging from the provider of first aid to the rehabilitation team. Examination and treatment of the injured patient at the site of an accident and during transport may be very difficult. This is of major importance, however, in order to bring the patient to the hospital under optimal conditions for the hospital treatment. Paramedics, primary care doctors and specialized emergency care teams are all important collaborators in this field. The specific decisions that are made at the various stages of treating a patient with multiple injuries will always be of fundamental importance for the patient.
