Victorian pilot data linkage: match rates and serious injury metrics sustained in on road transport crashes

A Victorian pilot project merging hospital, police and TAC data for one year was established. The dataset includes 68,639 cases of transport/road-related injury; 62% of which were from an on-road crash. Dataset linkage rates of cases showed 33% were police-reported crashes with no hospital data link; 10% were police-reported with a hospital admission; 10% were police-reported linked to an emergency only presentation and 45% had hospital data with no link to a police report. 14% of cases had MAIS2+ injury levels accounting for more than 81% of the total burden of injury.
