This post hoc analysis aimed to identify factors associated with improved clinical outcomes in patients switching to PP1M (75–150 mg eq.).Methods: The improved patient outcomes were observed as Positive and Negative Symptom Scale (PANSS, symptoms) score <70:66.7% (407/610), Personal and Social Performance (PSP, function) score >70:34.3% (199/581), and Involvement Evaluation Questionnaire (IEQ, caregiver burden) reduction ≥6:50.2% (270/538). Independent variables including demographics, disease duration, employment status, and clinical scores were screened individually using a univariate analysis and subsequently, variables (cutoff p<0.15) were analyzed using a multivariate regression analysis for association with better clinical outcomes at week 13.Results: The factors significantly associated with favorable clinical outcomes were reduction in PANSS at week 5 (odds ratio [OR]=1.14, 95% CI=1.11–1.17) with symptom reduction; baseline PSP total score (OR=1.07, 95% CI=1.05–1.10), PSP change at week 5 (OR=1.07, 95% CI=1.05–1.10), PANSS reduction at week 5 (OR=1.06, 95% CI=1.03–1.08) with functional improvement, reduction in PANSS at week 5 (OR=1.02, 95% CI=1.01–1.03), and total IEQ score at baseline (OR=1.09, 95% CI=1.07–1.11) with caregiver burden reduction.Conclusion: Thus, symptom and functional improvements with caregiver burden reduction were observed in patients, and PANSS reduction at week 5 was commonly associated with favorable outcomes.
