- The clinical distinction between schizophrenia and affective psychoses is often not clear-cut, and very little is known about the effectiveness of treatments among patients having both schizophrenia and affective symptoms.ObjectivesTo study the comparative real-world effectiveness of antipsychotic treatments among patients having schizophrenia and affective symptoms.MethodsWe studied the risk of all-cause rehospitalization during use of specific antipsychotics during 1996–2012 among all patients who had been previously hospitalized with both schizophrenia and mood disorder diagnoses in Finland since 1987 (n = 28,015). We linked nation-wide databases on hospitalization, mortality, and filled prescriptions. The primary analysis was within-individual analysis, in which each individual was used as his/her own control to eliminate selection bias. The effect of concomitant psychotropic medications, and the temporal orders of exposure and non-exposure periods were adjusted.ResultsWhen 22 specific antipsychotic treatments were compared with the most frequently used antipsychotic quetiapine, the lowest rehospitalization risks were observed during the treatment periods of olanzapine long-acting injection (LAI) (HR: 0.52; 95% CI: 0.34–0.80), risperidone LAI (0.67; 0.56–0.81), and clozapine (0.68; 0.63–0.74). The worst outcome was observed for periciazine (1.19; 0.96–1.48) and no antipsychotic use (1.09; 1.04–1.13).ConclusionsOlanzapine LAI, risperidone LAI, and clozapine use are associated with the lowest risk of rehospitalization among patients with schizophrenia and affective symptoms.Disclosure of interestJari Tiihonen has served as a consultant to The Finnish Medicines Agency Fimea, AstraZeneca, Bristol-Myers Squibb, Eli Lilly, F.
