Crash Outcomes Data Evaluation System (CODES)

Link crash report data with health outcomes data; provide reports and technical information; present results at state and national conferences; maintain CODES website.

The purpose of the Peer to Peer Demonstration from September 1999 to September 2002 was to link computerized databases including crash reports, hospital discharge data, Medicaid and Medicare claims, and paramedic data, using AUTOMATCH probabilistic linking software.
