| Popis: | Introduction Long-acting injectable (LAI) antipsychotics and community treatment orders (CTOs) are used in patients with schizophrenia to improve treatment effectiveness through adherence. Objectives Understanding healthcare resource utilization (HRU) and associated costs, and medication adherence in patients with schizophrenia overall and by CTO status before and after second generation antipsychotic (SGA) LAI initiation may guide strategies to optimize health. Methods A retrospective observational single-arm study using administrative data from Alberta was performed. Adults with schizophrenia who initiated SGA-LAI (index date) were included. Medication possession ratio (MPR) was determined; paired t-tests were used to examine differences in HRU and costs ($CDN) between the 2-year pre-index period and 2-year post-index period. Stratified analysis by presence or absence of an active CTO during the pre-post periods was performed. Results Among 1,211 patients who initiated SGA-LAIs, MPR was greater post-index (0.84) compared with pre-index (0.45; 95% confidence interval [CI] 0.36, 0.41). All-cause and mental health-related HRU and costs were lower post-index versus pre-index (p |
