Disasters are common events in the United States. They generally result in casualties and community hospitals play a critical role in caring for these victims. Therefore, it is critical that hospitals are prepared for disasters. There has been increased focus on hospital disaster preparedness in the United States because of events that have occurred in the 21st century. To determine the current state of disaster preparedness among community hospitals, a comprehensive review of the literature was conducted that focused on studies and other articles pertaining to disaster preparedness in U.S. community hospitals. The review showed mixed results as to whether hospitals are better prepared to handle disasters. Barriers to preparedness were identified. Opportunities for improvement may require additional study and involvement by federal and state governments, other agencies, and hospitals themselves to overcome barriers and assist hospitals in achieving a higher level of preparedness.
