Abstract

Objective: Schizophrenia is a chronic, debilitating psychiatric disorder with a high risk of relapse. Nonadherence to medication is a significant contributor to poor outcomes. Although long-acting injectable (LAI) antipsychotics prevent the relapse of schizophrenia, several factors present obstacles to the use of LAI antipsychotics, and clinical guidelines for LAI antipsychotics remain limited. To provide clinical recommendations, the Taiwanese Society of Biological Psychiatry and Neuropsychopharmacology (TSBPN) developed consensus statements for the effectiveness, target populations, initiation timing, and particular clinical situations for the use of LAI antipsychotics in patients with schizophrenia. Methods: After a systematic literature review, a working group drafted consensus statements for the selected clinical topics and determined the levels of evidence-based recommendation based on the latest World Federation of Societies of Biological Psychiatry grading system. A scientific committee evaluated the draft statements and decided the final recommendations regarding the grades by anonymous voting after incorporating clinical experience and practice into the evidence from research. Results: The TSBPN proposed ten consensus statements for the application of LAI antipsychotics. The current evidence supported that LAI antipsychotics could be a treatment option for all schizophrenia patients, including first-episode patients. LAI antipsychotics could be initiated both during an acute psychotic episode and when patients are stable. The consensus also gave recommendations for particular clinical situations with insufficient scientific data, such as for use in elderly or adolescent patients, patients with treatment-resistant schizophrenia, and breakthrough psychosis, and strategies to assist patients/caregivers with decision making. Conclusions: The consensus statements developed by the TSBPN provide evidence-based clinical recommendations and could give clinicians more confidence when prescribing LAI antipsychotics to treat schizophrenia, thereby improving treatment outcomes.
