This monograph discusses the concept of an effective sports accident data system, various systems in existence at the state and national levels, and basic considerations for the development of such data systems in sports. The document is divided into six chapters providing a framework for investigating the "state of the art" of accident data systems. Chapter One, the introduction, presents a broad outline for the development of an effective reporting system, and the need for initiating this process. Chapter Two discusses national general data systems that include information on sports accidents, and Chapter Three investigates similar systems existing at the state level. Chapter Four surveys selected accident data systems specifically dealing with sports, including the National Athletic Injury Reporting System, annual surveys of football injuries, accident data available through statewide insurance benefit plans, and examples of specialized accident data studies for selected sports. Chapter Five examines basic considerations for developing accident data systems in sports including the following processes: organization, reporting, investigation, data summarization, and data analysis. Chapter six summarizes the value to be gained from instituting an effective accident data system. A bibliography of ninety-nine citations is appended. (MJB)
