The document discusses the Hospital Incident Command System (HICS), which is an incident management structure used nationally in hospitals to provide a standardized chain of command and job descriptions for responding to emergencies. HICS provides an organizational framework for hospitals' emergency management plans. All hospitals in the DFW region have adopted HICS, as required by The Joint Commission. HICS can be used for drills, mass casualty incidents, large scale disasters, and internal incidents. It divides response activities into functional areas including planning, finance, logistics, and operations.
