Background: Self-inflicted poisoning is common in adolescents and is a risk factor for suicide. The aim of this study was to survey the circumstances surrounding hospitalisations due to acute poisoning in patients aged up to 18 years.
Material and method: All hospitalisations in the Departments of Paediatric and Adolescent Medicine, Sørlandet Hospital Trust (Arendal and Kristiansand) due to acute poisoning in the period 1 August 2014-31 July 2015 were prospectively recorded with the aid of a form completed during the admission.
Results: There were 88 hospitalisations distributed among 68 adolescents (mean age 15.5 years, SD 1.5) and 13 children (mean age 2.8 years, SD 2.8). The poisoning was categorised as self-harm behaviour in 32 (47 %) of the adolescents, and as substance misuse-related in 35 (52 %). In total, 37 (54 %) of the adolescents had been or were under treatment at the Department of Child and Adolescent Psychiatry. Fifteen (22 %) of the adolescents were deemed to be suicidal. Thirty (94 %) of the adolescents who reported self-harm as the intention behind their poisoning were offered further follow-up at the Department of Child and Adolescent Psychiatry, along with 7 (20 %) of the group with substance misuse-related poisoning.
Interpretation: Adolescents who reported self-harm as their intention were usually offered further follow-up, whereas adolescents with substance misuse-related poisoning were rarely offered follow-up.
