What Is Injury; Classification & Types Of Injuries

What Is Injury?

What is Injury – Injury, also known as physical trauma, represents damage to the body caused by external force; it is a general term that refers to harm caused by accidents, falls, hits, weapons, and more. It can range from Physical, Mental, and Psychological.

In the U.S., millions of people injure themselves every year. These injuries range from minor to life-threatening. Injuries can happen at work or play, indoors or outdoors, driving a car, or walking across the street.

In 2013, 4.8 million people world-wide died from injuries, up from 4.3 million in 1990. More than 30% of these deaths were transport-related injuries. In 2013, 367,000 children under the age of five died from injuries, down from 766,000 in 1990. Injuries are the cause of 9% of all deaths, and are the sixth-leading cause of death in the world.

Classification of injury

The World Health Organization (WHO) developed the International Classification of External Causes of Injury (ICECI). Under this system, injuries are classified by:

  • Mechanism of injury;
  • Objects/substances producing injury;
  • Place of occurrence;
  • Activity when injured;
  • The role of human intent;

These codes allow the identification of distributions of injuries in specific populations and case identification for more detailed research on causes and preventive efforts.

The United States Bureau of Labor Statistics developed the Occupational Injury and Illness Classification System (OIICS). Under this system injuries are classified by:

  • Nature,
  • Part of body affected,
  • Source and secondary source, and
  • Event or exposure.

The OIICS was first published in 1992 and has been updated several times since.
