Long-Acting Injectable Risperidone and Hospital Readmission: A Mirror-Image Study Using a National Claim-Based Database in Taiwan

J Clin Psychiatry 2009;70(1):141 [letter]

Letter to the Editor

Sir: Poor compliance with antipsychotic medication, which would potentially lead to disease relapse, has been challenging for psychiatrists when treating schizophrenia. Long-acting injection of antipsychotics is an appropriate alternative, since better compliance improves treatment outcomes. Mirror-image studies, in which each patient acts as his/her own control, of long-acting injection of conventional antipsychotics have shown significant decreases in numbers of hospitalizations and days of hospitalization.
