  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 ]

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

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.

Estimated Enrollment: 4500
Study Start Date: September 2007
Estimated Study Completion Date: October 2011
Groups/Cohorts
1
randomly stopped drivers of motorised vehicles and bicycles
2
drivers of motorised vehicles and bicycles injured or killed in road traffic accidents
