Demographics, Velocity Distributions, and Impact Type as Predictors of AIS 4+ Head Injuries in Motor Vehicle Crashes

This paper, from a conference on crash injury control, reports on a study undertaken to determine differences between the United States-based National Automotive Sampling System (NASS) and the Crash Injury Research Engineering Network (CIREN), compared to the Australian National In-depth Crash Study (ANCIS) databases. The authors focused on occupant-, crash-, and vehicle-related parameters for Abbreviated Injury Scale (AIS) 4+ head injuries in motor vehicle crashes. They analyzed the data to examine roles of the change in velocity (DV), crash type (frontal, far-side, nearside, rear impact), seatbelt use, and occupant position, gender, age, stature, and body mass in cranial traumas. Belted and unbelted non-ejected occupant (age older than 16 years) data from 1997-2006 were used for the NASS and CIREN datasets, and 2000-2010 for ANCIS. Vehicle model year, and occupant position and demographics including body mass index (BMI) data were also obtained. The researchers found that side impacts contributed to over one-half of the ensemble, implying susceptibility to head trauma in this mode. The odds of sustaining head injury increased by 4% per unit increase in DV; by 50% for belted compared to unbelted occupants. Risk for nearside, then far-side had significantly higher odds of sustaining head injury than frontal crashes; and no difference was found by gender or position (front-left, front-right). The authors conclude that these data support the call to revise the acceleration-based head injury criterion to include the angular component in an appropriate format for improved injury assessment and mitigation.
