Abstract
This study evaluated the prescription trends, patterns and associated factors of antipsychotic medication in children and adolescents. We conducted a retrospective study by using the database of outpatient health insurance files of a psychiatric center in Northern Taiwan from 2004 to 2013. A total of 173,209 outpatient health insurance files were included. The average age of the study patients was 11.3 (±3.9) years. Of all visits of the patients, 13.4% were prescribed antipsychotics. The prescription rate of all antipsychotic medication types in all the outpatients aged ≤18 years increased yearly by 0.6%. The prescription rate of first-generation antipsychotics decreased with an estimated average annual percent change of 5.6% (p < .001). By contrast, the prescription rate of second-generation antipsychotics increased with an estimated average annual percent change of 3.4% (p <.001). Multiple logistic regression analysis was performed to examine clinical factors (age, sex and diagnosis) associated with antipsychotic prescription. After adjusting for other variables, antipsychotic prescription was found to be increased by 1.31 times every year with age and by 1.06 times in the male patients. The patients with diagnoses other than schizophrenia appeared less likely to be prescribed antipsychotics. Antipsychotic medications are being increasingly prescribed to children and adolescents in recent years. T he efficacy and safety of antipsychotics in children and adolescents warrant clinical attention.
