Within the Dutch Paediatric Surveillance System (NSCK), all paediatricians report adolescents and fill in a questionnaire, making use of a patient interview.Results in total 5893 adolescents were treated, mainly (4,678; 88%) related to severe alcohol intoxication; mean age was 15.4 years, and 52% were boys. BAC level increased during this period (1.82 in 2007 and 2.01 in 2016), and reduced consciousness lasted from 2.24 hours in 2007 till 3.12 hours in 2016). 11.4% Of the adolescents with alcohol intoxication had simultaneous drug usage.
