摘要: Abstract Objective The primary aim of this study was to compare the impact risperidone long-acting injectable (R-LAI) other antipsychotics on rates hospitalisation in real-life settings. Method Cohort for General Schizophrenia (CGS) followed 1859 patients diagnosed with schizophrenia (DSM-IV) from 177 psychiatric wards public and private hospitals across France over a mean period 12 months. These were ambulatory or had been hospitalised less than 93 days at entry. Recruitment stratified second-generation antipsychotic use. A multivariate Poisson regression adjusted confounding propensity scores allowing autocorrelation used calculation relative 95% confidence intervals. Results age participants 37.65 years, 68.3% male 36.7% Altogether, accumulated 796 hospital stays (53.4 per 100 person-years). R-LAI slightly younger more often past 12 months compared non-R-LAI users. analysis showed use be associated lower rate future hospitalisation: 0.66 [0.46–0.96] use, 0.53 [0.32–0.88] LAIs. Conclusion Use non-use R-LAI.
