Comparison of Trauma Patient Injuries and Outcomes for ATV, Motorcycle, and Snowmobile Accidents


This retrospective study is being performed to inform and improve trauma care for ATV, motorcycle, and snowmobile accidents in the largely rural patient population of Essentia Health-St. Mary's Medical Center. The four specific aims of the study are to:

  1. Identify injury patterns from patients admitted with helmeted and non-helmeted ATV, motorcycle, and snowmobile accidents.
  2. Compare injuries and mortality rates between the three vehicle types, and with motor vehicle crashes.
  3. Identify risk factors for worse injury, modifiable risk factors, and injury prevention opportunities for decreased mortality and morbidity.
  4. For each of the above aims, evaluate for a change in injury pattern, vehicle crash type, mortality rates and associated risk factors during the COVID-19 pandemic.

Dr. Kristin Colling is the Principal Investigator. Melissa Harry, PhD, is the Co-Investigator.
