Level IV and V Trauma Center
In the United States, a Level IV trauma center provides advanced trauma life support prior to patient transfer in remote areas in which no higher level of care is available. The key role of the Level IV center is to resuscitate and stabilize patients and arrange for their transfer to the closest, most appropriate trauma facility. Hospitals are designated as a Level IV trauma center by the American College of Surgeons for a period of three years. Level V trauma centers are not formally recognized by the American College of Surgeons, but they are used by some states to further categorize hospitals providing life support prior to patient transfer to higher level centers.
