Prepare in advance for a natural disaster

Emergency preparedness – an overview


Emergency preparedness encompasses the planning and response to disasters. A disaster is defined by the World Health Organization (WHO) as a sudden phenomenon of sufficient magnitude to overwhelm the resources of a hospital, region, or location requiring external support.[1] Based on this definition, a disaster could be as massive as the terrorist attacks of September 11, 2001, or as small as a single patient with an infectious disease.

Defining a disaster ultimately depends on the type of event, timing, the severity of illness or injuries, local preparedness, and resources available. Disasters are either internal or external disasters. Internal disasters are events that occur within the walls of the hospital itself, such as an active shooter, power outage, or radiation exposure.[2]

External disasters occur at locations separate from the hospital, such as transportation incidents or industrial accidents. Disasters can be both internal and external disasters concomitantly, such as natural disasters that cause mass casualties as well as damage hospital structure.

Disasters can be acute or ongoing. Acute disasters have a general time of onset of the time of an event occurring. Acute disasters have a typical patient flow, which produces numerous low acuity patients presenting to the hospital, overwhelming the surge capacity, or the number of patients the facility can care for presenting at a single time. This surge event is followed by the majority of patients presenting by personal transport and later EMS or prehospital transport of the critically ill. Peak volumes in acute disasters are expected at two to three hours post-event. Evolving disasters such as infectious pandemics have a gradual progression to critical populations, but volumes and resource strain remain for extended periods.

Disaster types can further subdivide into categories such as natural disasters, chemical disasters, and bioterrorism; each subdivision produces a specific injury or exposure profile and individual strain on resources that can guide emergency preparedness planning and response …
