The Treatment of Children and Adolescents with Substance-Related Disorders in the German Health Care System - a Quantitative Study This study evaluates the minimum characteristics of OPS code 9-694 for specific treatment in special settings for substance-related disorders in children and adolescents. The research questions to be answered are the extent to which given minimum characteristics and potentials are assessed as practical, up-to-date, needs-oriented and necessary. The survey was conducted using a nationwide online survey in special wards of child and adolescent psychiatric clinics. Given minimum characteristics reflect everyday clinical practice and are assessed as practical, up-to-date and relevant. Nevertheless, setting- and method-specific potential for further development was identified, most of which has already been implemented in the clinics but has not yet been incorporated into the minimum characteristics. The topic has received little research attention to date. The findings of the original study can provide a basis for the optimization and adaptation of minimum characteristics and treatment offers for children and adolescents with substance-related disorders and lead to the further development of the OPS code. A theory-practice transfer tailored to the target group requires the networking of individual players in the help system as well as the health policy discussion and gradual adaptation of the content of given minimum characteristics and potential for change.
