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.
