  Purpose

The main purpose of the study is to determine the accident risk when driving under the influence of psychoactive substances, including alcohol (DUI). Other aims are to find out the prevalence of psychoactive substances in road traffic and to obtain information on the role of these substances in road traffic accident causations.

For the purposes of the study, drivers of motorised vehicles are randomly stopped and interviewed and breath alcohol is recorded. Also, an oral fluid sample is taken and psychoactive substances are investigated in the laboratory. For cases, drivers injured in traffic accidents are asked to participate to the study. A whole blood sample and, if possible, an oral fluid sample is taken and psychoactive substances are determined in the laboratory. Also, people diseased in road traffic accident are included in the study. The information required for these subjects are taken from a register database.

The study is part of an EU-project DRUID. Altogether 13 European countries take part to the study.


Condition
Prevalence of Psychoactive Substances in Road Traffic
Psychoactive Substances in Accident Involved Drivers
Relative Risk Estimation of Accident Involvement for Impaired Drivers

Study Type: Observational
Study Design: Observational Model: Case Control
Official Title: DRUID Work Package 2 - Epidemiology

Further study details as provided by National Institute for Health and Welfare, Finland:

Primary Outcome Measures:
  • relative risk estimation of accident involvement for drivers impaired by psychoactive substances [ Time Frame: three years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • prevalence of psychoactive substances in the general driving population [ Time Frame: three years ] [ Designated as safety issue: Yes ]
  • prevalence of psychoactive substances among accident involved drivers [ Time Frame: three years ] [ Designated as safety issue: Yes ]

Biospecimen Retention:   Samples With DNA

Whole blood and oral fluid are collected for the study. However, no DNA determinations are done at any point of the study. The laboratory where the samples are analysed does not analyse DNA. DNA is not relevant for this study.
