Objective This study aims to investigate the sociodemographic characteristics, diagnosis and treatment distributions, age variability, and factors predicting multiple drug use among children and adolescents who applied to a private child and adolescent psychiatry outpatient clinic. Materials and methods The files of 718 patients who applied to the Psychiatry Institute for 12 months between March 2019 and March 2020 were evaluated retrospectively. Files of 25 patients were excluded due to missing data. During the first application to the outpatient clinic, an evaluation was made based on the semi-structured interview form and the psychiatric examination information made with the patient file. The information received from the family and the patient was processed. According to DSM V, psychiatric diagnoses were made by the child psychiatrist after an average of 50 minutes of a clinical interview. Results The data of 693 patients between the ages of 2-18 (8.4 ± 4.5) were evaluated. 38.3% of the patients were female, and 61.2% of them were male. The most common diagnoses were Attention Deficit and Hyperactivity Disorder (ADHD) (34.4%), normal mental examination, and Generalized Anxiety Disorder, respectively. The retrospective elimination method performed to predict the use of more than one psychiatric drug was performed with logistic regression analysis, and it was observed that the model was significant and male gender (OR: 2.61) and comorbid psychiatric disease (OR: 1.11) predicted the use of more than one psychiatric drug. Conclusion In our study, the sociodemographic characteristics, frequency of diagnosis, and drug treatments applied after examination of patients aged between 2 and 18 years who applied to a child, and adolescent psychiatry outpatient clinic were discussed. Similar studies of clinics in different geographical regions in our country will clarify the diagnosis and treatments frequently encountered.
