Increased mortality among previously apprehended drunken and drugged drivers.
Most studies in the field of impaired driving have focused on the hazards imposed on society by the impaired drivers, whereas little attention has been paid to the future outcome of the drivers. The aim of the study was to identify mortality rates and causes of death among drunken and drugged drivers during the years after apprehension. Prospective cohort study on apprehended drunken and drugged drivers, follow-up period: 7.5 years, outcome variable: death. Apprehended drivers 20-39 years old who provided samples positive for alcohol (n=2531) or drugs other than alcohol (n=918) constituting the total national samples of these two driver categories in 1992. The mortality rate among male drunken drivers was higher than in an age-matched Norwegian population (standardised mortality ratio, SMR=3.7 (95% Cl 2.9-4.7). The SMR for drugged drivers was 18.1 (14.9-21.8) for men and 27.9 (14.4-48.8) for women. In a subgroup of male drugged drivers using heroin, SMR was 39.8 (28.8-53.6). The dominant causes of death among drunken and drugged drivers were drug poisoning/overdose, accidents and suicide. Apprehension for drunken or drugged driving and subsequent analytical verification, is an indicator of increased risk of future premature death in the age group 20-39 years, particularly for drugged drivers. To our knowledge this is a new finding, and studies to confirm it should be carried out in other countries. If verified, the results should lead to the consideration of new public health approaches towards apprehended impaired drivers.
