Mass casualty incident defined

Define and distinguish the terms disaster and mass casualty incident (MCI) in relation to other major incidents or emergency situations. 

Mass casualty incidents (MCI) are defined as situations with a larger number of casualties produced in a relatively short period of time, usually as the result of a single incident such as accidents, natural disasters, or acts of terrorism. These events are also expected to exceed normal capacities of health care systems in terms of logistics, persormel, and maximum achievable individual care (Levi et al. 2002 Arnold et al. 2003).
