• Abstract:
  Analyses of the benefits of safety belt and helmet use were undertaken for a Report that was sent to Congress February, 1996. NHTSA awarded grants to link crash and injury state data and perform the analyses upon which the report was based. The individual state estimates are reported in the Crash Outcome Data Evaluation System (CODES) Technical Report which describes the linkage and analytical processes used in the CODES project. The study employed probabilistic linkage methods whereby statewide data from police crash reports, emergency medical services, hospital emergency departments, hospital discharge files, claims, and other sources were linked so that those people injured in motor vehicle crashes could be followed through the health care system. Linkage of population-based state data enabled information for both the injured and uninjured to be used to determine the benefits of safety belts and helmets in motor vehicle crashes. It also provided access to financial information. This was the first time these databases were linked using a probabilistic computer algorithm. CODES demonstrated that linked comparable data could be generated to evaluate the benefits of belts and helmets in terms of medical and financial outcome. Data linkage enabled injury severity to be standardized among the CODES states. Of even more importance is the fact that the linkage identified previously unknown problems with missing and inaccurate data. Correcting these problems for the study improved the quality of the data in the permanent files.
