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.

Detailed description

Introduction and Background: Horse-related activity (HRA) can be risky. The National Electronic Injury Surveillance System (NEISS) estimated that in 2006, 68,060 Americans went to a U.S. emergency room with horse-related injuries (HRI), of which 5,676 were hospitalized. However, Thomas et al estimated that 102,904 people each year from 2001 to 2003 were treated for HRI in emergency rooms nationwide. In Oregon, 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. In a survey of 679 Northwest equestrians in Oregon, Washington, and Idaho, 81% riders reported at least one injury during their career, and 1 in 5 equestrians required hospitalization, surgery, or sustained permanent disability as a result of a HRI. The long-term goal of our research is to develop a horse-related injury prevention program. Our preliminary study indicated that lower levels of experience were strong indicators of greater risk. The period of greatest danger appears to be during the initial 100 hours of HRA, with the incidence of injury nearly 8 times greater among novices as compared to instructors or professionals. The extent to which HRI is preventable is currently not clear, but it may be substantial. 64% of injured, experienced riders believed their incident was preventable and 47% altered their riding habits as a result. Rationale: There is a need to develop specific safety and prevention recommendations to reduce the number of HRIs. We intend to retrospectively determine what decisions, conditions, or other influential circumstances occurred that led to the subject's injury incident and to question the subject whether any measures could have prevented the incident from occurring. By interviewing injured equestrians, we may be able to determine patterns of decision-making and behavior from their collective experience and develop useful safety recommendations. The investigators will also interview injured equestrians to determine the impact that the injury has had on their quality of life. There is very little information in the literature on this subject. One study indicated that in the pediatric population, 41% of injured children and adolescents had residual complaints and were still hampered in their daily activities an average of 4 years after HRI. If we can document what we suspect will be a high impact of HRI on quality of life in both adults and children, the imperative to develop injury prevention measures will be further supported. 2\. Briefly summarize how participants are recruited. The Trauma Service at OHSU keeps a state-mandated registry of all patients admitted to the Trauma Service that can be searched by injury diagnosis code. Demographic, injury, and hospital outcome data can be easily obtained and matched. Consenting subjects who were treated at OHSU between January 1, 2001 and September 20, 2008 will be contacted by mail and asked to participate in this study. Potential subjects who are currently \> 18 years of age can be included in the study if a Child Assent Form has been completed and a legally authorized representative (LAR) provides consent for study participation. . Investigators will be available to answer any questions that subjects may have concerning the study. 3\. Briefly describe the procedures subjects will undergo. This study involves responding to an electronic survey that will be emailed to subjects agreeing to participate in this research study. Subjects will not undergo any physical procedures. The researchers may contact study participants by email or telephone if necessary, to clarify responses from the survey questionnaire. 4\. If applicable, briefly describe survey/interview instruments used. Study participants will respond to an equestrian survey that asks questions about the horse-related injury, including causes and circumstances surrounding the injury, experience and skill level at the time of injury, safety equipment used, ideas on how the injury might have been prevented, how it has impacted quality of life, and current health status, work status, and activity level. Study participants will also complete the Rand 36-Item Health Survey, a short survey that evaluates health status. A single survey, emailed to the subject, will include both the equestrian survey and the Rand 36. Completion of the survey will require approximately 30 minutes. 5\. Briefly describe how the data will be analyzed to address the purpose of the protocol. The responses to our study questionnaires will allow us to perform statistical analysis to determine the causes and circumstances surrounding the injury to see if safety prevention measures can be identified. It will also assess the impact of the injury on the quality of life.

Design outcomes

Primary

MeasureTime frameDescription
Injury Severity Score (ISS)2008-2011The 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.
