CODES (Crash Outcome Data Evaluation System) is a collaborative approach to obtain medical and financial outcome information related to motor vehicle crashes for highway safety and injury control decision making. It evolved as the result of the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 which provided funds to the National Highway Traffic Safety Administration (NHTSA) to report to Congress about the benefits of safety belts and motorcycle helmets for persons involved in motor vehicle crashes. To measure benefits in terms of reducing death, disability, and medical costs, NHTSA determined that statewide data were needed that included all persons involved in police-reported crashes -- those who were injured or who died as well as those who were not injured.

Wisconsin was one of seven states to receive a grant in 1992 from the U.S Department of Transportation (DOT), National Highway Traffic Safety Administration (NHTSA) to participate in the development of a Crash Outcome Data Evaluation System. The number of states involved in the national CODES project has increased to 20 States including Alaska, Connecticut, Hawaii, Iowa, Kentucky, Maine, Maryland, Minnesota, Missouri, Nebraska, Nevada, New Hampshire, New Mexico, North Dakota, Oklahoma, Pennsylvania, South Carolina, South Dakota, Utah, and Wisconsin.

As a result of this grant and additional funding provided by the Bureau of Transportation Safety within the Wisconsin Department of Transportation (WisDOT), Wisconsin has developed a computerized system for linking Wisconsin Hospital Discharge data with Wisconsin Crash data. Because personal identifiers are limited in the data, a probabilistic linking process was used to merge hospital discharge and crash data. Annual data from 1992 to 2002 is available from this study.
