AbstractThe Hospital Emergency Incident Command System (Hospital Emergency Incident Command System), nowin its third edition, has emerged asa popular incident command system model for hospital emergency response in the United States and other countries. Since the inception of the Hospital Emergency Incident Command System in 1991, several events have transformed the requirements of hospital emergency management, including the 1995 Tokyo Subway sarin attack, the 2001 US anthrax letter attacks, and the 2003 Severe Acute Respiratory Syndrome (Severe Acute Respiratory Syndrome) outbreaks in eastern Asia and Toronto, Canada.Several modifications of the Hospital Emergency Incident Command System are suggested to match the needs of hospital emergency management today, including: (1) an Incident Consultant in the Administrative Section of the Hospital Emergency Incident Command System to provide expert advice directly to the Incident Commander in chemical, biological, radiological, nuclear (CBRN) emergencies as needed, as well as consultation on mental health needs; (2) new unit leaders in the Operations Section to coordinate the management of contaminated or infectious patients in chemical, biological, radiological, nuclear emergencies; (3) new unit leaders in theOperations Section to coordinate mental health support for patients, guests, healthcare workers, volunteers, anddependents in terrorismrelated emergencies or events that produce significant mental health needs; (4) a new Decedent/Expectant Unit Leader in the Operations Section to coordinate the management of both types ofpatients together; and (5) a new Information Technology Unit Leader in the Logistics Section to coordinate the management of information technology and systems.New uses of the Hospital Emergency Incident Command System in hospital emergency management also are recommended, including: (1) the adoption of the Hospital Emergency Incident Command System as the conceptual framework for organizing all phases of hospital emergency management, including mitigation, preparedness, response, and recovery; and (2) the application of the Hospital Emergency Incident Command System not only to healthcare facilities, but also to healthcare systems.Finally, three levels of healthcare worker competencies in the Hospital Emergency Incident Command Systemare suggested: (1) basic understanding of the Hospital Emergency Incident Command System for all hospital healthcare workers; (2) advanced understanding and proficiency in the Hospital Emergency Incident Command Systemfor hospital healthcare workers likely to assume leadership roles in hospital emergency response; and (3) special proficiency in constituting the Hospital Emergency Incident Command System ad hoc from existing healthcare workers in resource-deficient settings. The Hospital Emergency Incident Command System should be viewed asa work in progress that will mature as additional challenges arise and ashospitals gain further experience with its use.
