American Trauma Society - Trauma Registrar Course - Distance Learning 

The American Trauma Society Trauma Registrar Course (TRC) introduces the student to the specialty of the trauma registrar and provides a standardized approach to the task of maintaining a trauma registry.  The TRC provides the student with national standard definitions and methodologies essential to a comprehensive trauma registry.  This course is available via distance learning.  The benefits of becoming a nationally trained trauma registrar include a standardized approach for valid data collection for use in supporting the trauma programs efforts in research, performance improvement & patient safety, and injury prevention.
