  Purpose

Official Title: Retrospective Study of Unrequested Analytical Data in DUID-cases From a 2 Week Period

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

Primary Outcome Measures:
  • assessment of both alcohol and drugs in suspected DUI cases [ Time Frame: 2 weeks ] [ 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 ]

Biospecimen Retention:   Samples With DNA

Whole blood samples are collected for the study. However no DNA detection is done at any point in the study. The laboratory where the samples are analysed does not analyse DNA. DNA is not relevant for this study

Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
Groups/Cohorts
1
drivers of motorised vehicles suspected of driving under the influence of psychoactive drugs or alcohol
2
drivers stopped in police traffic controls and breathalysed positive for alcohol

Detailed Description:

There are 3 different possibilities for forensic analysis of suspected driving under the influence samples. Testing for alcohol or drugs only or testing for both alcohol and drugs.

Often if the primary suspicion of the apprehending police officer is of driving under the influence of drugs or alcohol then only laboratory analysis concerning that primary suspicion is requested.

The study aims to provide information about those 'missed cases' where only analysis for drugs or alcohol is carried out. Traffic police samples from a 2 week period are to be screened for both drugs and alcohol, even if the primary suspicion is only one of these.

The study is part of the EU-project DRUID. Altogether 13 European countries are participating in DRUID.
