INTRODUCTION: Patients with major depressive disorder (MDD) often fail to respond to first-line antidepressant treatments (ADTs); subsequent strategies include dosage increase, switch to a different ADT, or addition of another ADT or other drug. The objective of this prospective, case review study was to identify factors that influence the decision to prescribe adjunctive antipsychotics for patients with MDD and inadequate response to ADT.
METHODS: Psychiatrists or primary care physicians (n=411) based in the USA and Europe each completed an online survey for ten consecutive adults with MDD and inadequate response to ADTs, and for whom a treatment change was considered. A t test was used to compare survey responses between groups of patients.
RESULTS: The survey was completed for 4018 patients; an adjunctive antipsychotic was considered for 961/4018 patients (23.9%) and actually prescribed for 514/4018 (12.8%). Compared with patients not considered for an adjunctive antipsychotic, those who were considered for this treatment had more previous major depressive episodes (MDEs), longer duration of the current MDE, more severe illness both at ADT initiation and current consultation, and more treatment changes. Patients who were prescribed adjunctive antipsychotics had at baseline more functional impairment and absences from work than those considered for but not prescribed this treatment. Key symptoms that prompted physicians to consider antipsychotics were psychotic symptoms, psychomotor agitation, hostility, irritability, impulsivity, and anger bursts. Anxious mood and irritability were mentioned significantly more often by physicians who actually prescribed adjunctive antipsychotics. Obstacles to prescribing included a tendency to wait to see if symptoms improved and concern over side effects.
CONCLUSION: This real-world study suggested that the decision to prescribe an adjunctive antipsychotic for patients with MDD and inadequate response to ADT is influenced by a broad spectrum of factors, predominantly related to severity of illness, functional impairment, and symptom profile.
