Impact of MRV Injuries

Motorized recreational vehicle (MRV)- related injuries are an important public health problem in Ohio. State safety legislation, vehicle design changes and training of MRV users offer important opportunities to prevent these costly injuries.

This study describes the epidemiology and clinical and economic impact of MRV-related injuries in Ohio during 2002-2003. We analyzed probabilistically-linked statewide EMS and hospital inpatient data for individuals with a MRV-related E-code (E820-E825) in either the EMS or hospital database, or both.

  • 538 patients were hospitalized for MRV-related injuries who had linked EMS and hospital inpatient records
  • Median patient age was 32 years (range 3 to 93 years)
  • Nearly 80% of cases were male
  • The majority of linked cases occurred in an urban area (66%) and had commercial insurance coverage (61%)
  • 25% of cases occurred on a street or highway, and among these, 40% sustained a traumatic brain injury (TBI) compared with 22% for those that occurred at another location
  • A helmet was worn in 36% of cases, and there was a trend of decreasing helmet use with increasing patient age
  • Alcohol was involved in 23% of cases, and 21% of cases involving alcohol wore a helmet
  • The mean Injury Severity Score was 9.0, and severe injury (ISS≥16) was sustained by 17% of cases
  • There were seven fatalities during the two-year study period
  • The median hospital charge was $12,243 per patient, with two-year cumulative hospital charges of $11.6 million. Median length of hospital stay was 3.0 days, with a range of 1 to 52 days. Mean length of stay among patients covered by federal insurance (6.0 days) was significantly longer than among patients covered by other types of insurance (3.9 days), after adjusting for ISS (p=0.02)
