There are typically many contributing factors in motor vehicle crashes. Emergency Medical Services (EMS) play a critical role post-crash to reduce fatalities and serious injuries. Recent studies show that an effective emergency trauma care system can improve survival from serious injuries by as much as 25 percent and county-level coordinated systems of trauma care can reduce crash fatalities rates as much as 50 percent.

The Haddon Matrix (see Figure 1) applies basic principles of public health to motor vehicle-related injuries. The matrix looks at the factors in the pre-crash, crash...
