Background: The aim of the study is to present the health predispositions to drive, assessed during certifying people referred to the Regional Centre for Occupational Medicine in Kielce due to drunk driving or driving after using alcohol. The article mainly presents the results regarding the prevalence of alcohol dependence and other psychiatric disorders in this group. We analyzed health condition at 3 year intervals in the years 2004, 2007 and 2010, adding the population of those who were examined in 2011.
Material and methods: A total of 5701 people were involved, both men and women. Drivers test cards along with the results of biochemical tests and specialist consultations were analyzed. The analysis of the results was performed using the statistical package PQStat 18.104.22.1684.
Results: Certificates with health contraindications to drive were issued to 6.7% of investigated individuals. Very significant correlation between alcohol dependence syndrome and the level of γ-glutamyl transferase (GGT), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were confirmed. Alcohol dependence was diagnosed in 3.8% of the group.
Conclusions: The health state of the drivers met the required certification criteria necessary for obtaining a driving license in more than 93% of the group. The study revealed many diseases in the group of investigated drivers, including 3.8% of alcohol dependence and 5% of mental disorders. The threat of losing driving license has become an important factor motivating drivers to undertake therapy. However, it seems advisable to develop principles for treatment monitoring and exchange of information between the certifying physician and the treating psychiatrist or psychologist.
