Methods This was a 24-month multicenter prospective longitudinal observational study in patients with schizophrenia who were initiated on RLAT. Physicians could change treatment during the study as clinically warranted. Data were collected at baseline and subsequently every 3 months up to 24 months. Effectiveness outcomes included changes in illness severity as measured by Clinical Global Impression-Severity CGI-S scale functional scores as measured by Personal and Social Performance PSP scale Global Assessment of Functioning GAF and Strauss-Carpenter Levels of Functioning LOF and health status Medical Outcomes Survey Short Form-36 SF-36 . Life-table methodology was used to estimate the cumulative probability of relapse over time. Adverse events were evaluated for safety. Results 532 patients were enrolled in the study 209 39.3 completed the 24-month study and 305 57.3 had at least 12 months of follow-up data. The mean SD age of patients was 42.3 12.8 years. Most patients were male 66.4 and either Caucasian 60.3 or African American 23.7 . All changes in CGI-S from baseline at each subsequent 3-month follow-up visit were statistically significant p .0001 indicating improvement in disease severity. Improvements were also noted for the PSP GAF and total LOF indicating improvement in daily functioning and health outcome. Conclusions Patients with schizophrenia who were initiated on RLAT demonstrated improvements in measures .
