The document discusses the handover process between different levels of care for patients, including prehospital care, care in the emergency department, and definitive care. It emphasizes providing only essential information during handovers, such as the patient's age, time and mechanism of injury, injuries, vital signs, treatments given, allergies, and medical history, rather than extraneous details. The handover process should include reviewing important information before providers leave to pass on to the next level of care.
