Evolution of
CODES

CODES is a collaborative approach to generating medical and financial outcome information relating to motor vehicle crashes and using this outcome-based data as the basis for decisions related to highway traffic safety.

CODES evolved as the result of the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 which provided funds to the National Traffic Safety Administration (NHTSA) to report to Congress about the benefits of safety belts and motorcycle helmets for persons involved in motor vehicle crashes. For the first time, benefits were to be measured in terms of reductions in:

Death
Injury
Injury Severity
Health Care Costs
In order to define benefits in these terms, medical and financial outcome information for all persons involved -the uninjured, the injured including injury severity, and the fatailities- would be needed about the crash and injury events at the scene, en route, at the emergency department and after admission to a hospital. NHTSA determined that crash data alone could not provide all of the necessary information. Statewide crash and injury data would have to be linked. The linked data could then be used to make comparisons of those using and not using safety belts or motorcycle helmets by identifying and contrasting the characteristics of the injured and uninjured persons within each of the restraint use groups.
 

The CODES Report, Report to Congress on Benefits of Safety Belts and Motorcycle Helmets, Based on Data from the Crash Outcome Data Evaluation System (CODES), was delivered to Congress in February 1996 and is available for download as a pdf document.
