Brief Summary

Horse-related activity can be risky. Horses are the leading cause of animal-related fatalities in Oregon and Oregon's annual death rate from animals is 45% higher than the national rate. By interviewing injured equestrians, the investigators may be able to determine patterns of decision-making and behavior from their collective experience and develop useful safety recommendations. The investigators will also determine the impact that the injury has had on quality of life. The long-term goal of the investigators research is to develop safety and prevention recommendations and a horse-related injury prevention program to reduce the number of horse related injuries.

Outcome Measures

Primary Outcomes (1)

  • Injury Severity Score (ISS)

    The Injury Severity Score (ISS) is based upon the Abbreviated Injury Scale (AIS) and is calculated by dividing the body into 6 regions. Each region is scored on a scale of 1 (minor severity/better) to 5 (most severity/worse). ISS total score is calculated by squaring each of the 3 most severely injured body regions, then summing the three squared numbers. Total ISS score can range from 3 to 75.

    2008-2011

Other Outcomes (5)

  • Helmet Use

    2001-2008

  • Preventable Head Injuries
