Crash Medical Outcomes Data

The Linked Crash-Medical Data come from the California Crash Medical Outcomes Data (CMOD) project, modeled on the National Highway Traffic Safety Administration (NHTSA) Crash Outcome Data Evaluation System (CODES). CMOD links data from police traffic crash records (i.e., scene investigations) to medical data (from emergency departments, hospitals, and, in a future update, death files). To learn more about CMOD data linkage, go to Help.

For 2007-2010, 55% of injury crash records linked to a medical record and 45% did not. There are valid reasons why some records do not link. Some crash victims are never treated in a hospital or emergency department, and thus there are no medical outcomes data to report. In other cases, records do not have enough information for a positive match. The value of a linked data set is that it can be used to show how a victim's medical outcome depends on the characteristics of the person (such as age) and the circumstances of the crash (such as the type of collision). Because linked data do not include all cases, they cannot be used to describe all crashes or all crash injuries. There are fewer linked cases for 2008 through 2010 than for 2007. This is consistent with a decrease in the number of crashes reported for 2008 through 2010. For describing all injuries, use EpiCenter’s other queries. For describing all crashes on California roadways, use the California Highway Patrol (CHP) SWITRS Reports CHP-SWITRS.

Funding for the CMOD Project and the online query is provided by a grant from the California Office of Traffic Safety through the National Highway Traffic Safety Administration.
