Objective: In this study it's aimed to evaluate the sociodemographic characteristics, psychiatric diagnoses, treatment options and improvement levels of the patients who were treated in Child and Adolescent Psychiatry inpatient service. Methods: One hundred and forty-nine patients between who were treated in Ege University Child and Adolescent Psychiatry inpatient service between March 2013 and September 2014 were evaluated. The patients' files were used for data collection and Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime version (K-SADS) was used for appropriate patients. Clinic Global Impression Scale-Severity (CGIS-S) was used for all cases for determining the psychiatric disorder severity and Clinic Global Impression Scale-Improvement (CGIS-I) was used for evaluating the treatment effect. Results: The age mean was 14.2. % 63.1 of the patients were girls and % 36.9 boys. The common diagnoses were mood disorders % 57.7, attention deficit and hyperactivity disorder % 10.7, schizophrenia and other psychotic disorders % 8.1. The mean treatment duration was 24.4 days. It is founded that the longer duration of hospitalization has positive effect on CGI improvement scores. All patients get psychopharmacological medication during inpatient follow up. The most used medication were antipsychotics. First CGIS-S median level of the patients was 5 (markedly ill) (range: 3-7) and 3 when discharging. When we compare the hospitalization and discharge CGI-S score medians of patients', a statistically significant difference was founded. Results: Although there is a limited number of inpatient services for children, the positive contribution of inpatient services on children and adolescents' mental health is incontrovertible unquestionable. This study is a preliminary report for forthcoming studies with special inpatient services for children and adolescent.
