Compulsory blood alcohol testing of road crash casualties in Victoria: the first three years.

The history, rationale and implementation of legislation for compulsory blood alcohol tests on adult road crash casualties presenting at Victorian hospitals are reviewed. Drinking drivers admitted to casualty departments can now be identified and prosecuted; doctors can obtain blood alcohol test results on road crash casualties without threat of litigation; drinking drivers with alcohol problems may be directed to appropriate re-education or rehabilitation programmes; the opportunity also exists for treatment of non-driver casualties with alcohol problems. In the first three years of testing, 27.1% of 21,863 male driver casualties had blood alcohol concentrations in excess of the legal limit of 0.05 g/100 mL (11 mmol/L), and 13.7% had blood alcohol levels in excess of 0.15 g/100 mL (33 mmol/L); the blood alcohol levels in 8.7% of 9187 female driver casualties exceeded 0.05 g/100 mL, and in 3.7% exceeded 0.15 g/100 mL. Non-drivers had a slightly lower incidence of elevated alcohol concentrations. The implementation of further drink-driving countermeasures, expansion of services for the management of alcohol problems, and development of a national policy directed at prevention of alcohol abuse are recommended.
