An accident, mishap, or, more archaically, misadventure, is an unforeseen and unplanned event or circumstance, often with lack of intention or necessity. It usually implies a generally negative outcome which may have been avoided or prevented had circumstances leading up to the accident been recognized, and acted upon, prior to its occurrence.
Experts[who?] in the field of injury prevention avoid use of the term 'accident' to describe events that cause injury in an attempt to highlight the predictable and preventable nature of most injuries. Such incidents are viewed from the perspective of epidemiology as predictable and preventable. Preferred words are more descriptive of the event itself, rather than of its unintended nature (e.g., collision, drowning, fall, etc.)
Accidents of particularly common types (crashing of automobiles, events causing fire, etc.) are investigated to identify how to avoid them in the future. This is sometimes called root cause analysis, but does not generally apply to accidents that cannot be deterministically predicted. A root cause of an uncommon and purely random accident may never be identified, and thus future similar accidents remain "accidental."
Physical and non-physical
Physical examples of accidents include unintended collisions or falls, being injured by touching something sharp, hot, or electrical, or ingesting poison. Non-physical examples are unintentionally revealing a secret or otherwise saying something incorrectly, forgetting an appointment, etc.
- Accidents during the execution of work or arising out of it are called work accidents. According to the International Labour Organization (ILO), more than 337 million accidents happen on the job each year, resulting, together with occupational diseases, in more than 2.3 million deaths annually.
- In contrast, leisure-related accidents are mainly sports injuries.
- Bike accidents
- Tram accidents
- Traffic collisions
- Train wrecks
- Sailing ship accidents
- Aviation accidents
Most common causes
Traffic accidents and falls are the most common causes of physical traumas or injuries leading to hospital care. According to a 2005 survey of injuries sustained at home, which used data from the National Vital Statistics System of the United States National Center for Health Statistics, falls, poisoning, and fire/burn injuries are the most common causes of death. The United States also collects statistically valid injury data (sampled from 100 hospitals) through the National Electronic Injury Surveillance System administered by the Consumer Product Safety Commission. This program was revised in 2000 to include all injuries rather than just injuries involving products. Data on emergency room visits is also collected through the National Health Interview Survey.
