Assessment of Characteristics of State Data Linkage Systems[PDF - 3 MB]

In 2013, the Centers for Disease Control and Prevention and the National Highway Traffic Safety Administration (NHTSA) conducted a joint study to increase knowledge about state data linkage systems*, including NHTSA’s Crash Outcome Data Evaluation System (CODES).

Twenty-five states with linkage programs integrating crash data with medical injury data were surveyed about their programs and nineteen participated in follow-up focus groups. The study also assessed State Traffic Record Assessments and other secondary sources. Assessment of the results of the data collections resulted in facilitators and barriers to successful linkage programs.

*Data linkage systems link crash report data to medical data.
