Atypical Antipsychotic Prescribing in Australian Children and Adolescents: A Survey of Medical Practitioners

Prescriptions for atypical antipsychotics in children and adolescents are increasing globally. However, a precise understanding of the clinical variables and evidence that prescribers consider before using these agents is lacking. While empirical literature on the long-term safety and efficacy of these medications is available, the literature concerning their use in these younger age groups is relatively sparse. In this study, we examined the current prescribing patterns of medical professionals employed by a public health service in Australia.

A survey examining their current practice when prescribing atypical antipsychotics to children and adolescents was completed by 103 physicians. Questions were asked about commonly prescribed atypical antipsychotics, indications, dose ranges, target symptoms, duration of treatment, and the evidence base(s) used when making treatment decisions.

Physicians prescribed atypical antipsychotics for a wide range of indications in this age group, with the most common agents being risperidone, quetiapine, and olanzapine. Adverse effects were reported as the main reason for treatment discontinuation. More than half of the respondents indicated that the most common source of guidance/evidence they referred to when initiating prescriptions were peers or expert opinion.

Children and adolescents were prescribed a number of atypical antipsychotics for a variety of indications, with variable perceived confidence and a relatively heavy reliance on "own or peer experience" as opposed to good quality evidence. Challenges exist for both prescribers and policymakers, and further "head-to-head" studies are needed in this age group to ensure that a balance is maintained between therapeutic benefit and safety.
