Methods: Data were derived from our statewide ATV injury surveillance database (2002-2009). Descriptive analyses were performed for demographics, risk factors (e.g., carrying passengers), crash mechanisms, and outcomes of injuries. Comparisons of categorical and continuous variables were performed.
Results: A total of 813 injured persons were included in the final analysis; 6% of victims were from OHV park crashes. Relative to outside the parks, a smaller percentage of park victims were under the age of sixteen (7% vs. 31%, p<0.01), a lower percentage were passengers (2.5% vs. 13%, p=0.07), and a dramatically higher percentage were helmeted (90% vs. 24%, p<0.0001). However, park crashes involved more jump-related injuries (34% vs. 5%, p<0.001). Mean injury severity scores were not different between the two locations, but 5% of victims outside the parks had severe brain injuries (GCS <8) as compared to no park victims.
Conclusion: OHV park crashes involved more jump-related events, suggesting that additional studies of individual parks may be necessary to identify high-risk areas and to improve park safety. However, park victims exhibited better compliance with ATV safety-related laws and regulations and suffered less severe brain injury outcomes. These findings support the hypothesis that ATV safety regulations accompanied by effective enforcement promote safe behaviors that may prevent injuries.
