Following the attacks of 11 September 2001, emergency preparedness within the U.S. Department of Health and Human Services, as well as at the Department of Defense and other federal agencies, received higher visibility, new mandates and increased funding. Emergency deployment teams increased the frequency of drills to enable better response to the health consequences of mass-casualty incidents. Interagency coordination has also continued to increase to more efficiently and effectively leverage federal resources toward emergency medical preparedness for both civilian and military populations.
