The economic burden of schizophrenia spectrum disorders: clinical and functional correlates and predictors of direct costs. A retrospective longitudinal study.

The economic burden of schizophrenia amounts for 1.5-3 % of healthcare expenses in developed countries, and ∼50 % derives from direct costs: 81 % of these are due to hospitalization, residential facilities and semi-residential facilities. Therefore, a better characterization of variables that influence direct costs represents a relevant issue. A total of 276 individuals with schizophrenia spectrum disorders receiving treatment from the Community Mental Health Centers of Brescia (Italy) were included in the study: for each participant socio-demographic, clinical and functional characteristics were assessed, and data related to the use of services in 2022 (then converted to costs) were collected. Regression analyses were performed to identify predictors of costs. A direct healthcare expenditure of 16477.23 (±32856.47) € per patient per year was identified. The main cost predictor was the PSP total score (p=0.005), followed by age of onset (p=0.020), and PANSS total score (p=0.033). Including PANSS sub-scales scores and PSP single items as potential predictors, the main predictor was the "socially useful activities" PSP item (p=0.002), followed by age of onset (p=0.011), and PANSS negative scale score (p=0.027). Our findings underline the need to implement rehabilitative intervention focused on the improvement of psychosocial functioning and negative symptoms, also to reduce healthcare expenses.

Long-acting Injectable Antipsychotics during the COVID-19 pandemic in schizophrenia: An observational study in a real-world clinical setting.

The COVID-19 pandemic is having an important impact on the practice of mental health services and on schizophrenia patients, and heterogeneous and conflicting findings are being reported on the reduction of long-acting injectable (LAI) antipsychotics use. Aims of the study were to assess the total number of patients treated with LAI, the start of novel LAI and the discontinuation of LAI treatments, analyzing register data of the first year of the pandemic, 2020, compared to a pre-pandemic reference year, 2019. Data from two outpatient centers were retrieved, for a total of 236 participants in 2020: no significant differences were observed comparing 2020 and 2019 when considering the total number of patients on LAI treatment (p = 0.890) and the number of dropouts (p = 0.262); however, a significant reduction in the start of LAI was observed (p = 0.022). In 2020, second generation LAI were more prescribed than first generation LAI (p = 0.040) while no difference was observed in 2019 (p = 0.191). These findings attest the efficacy of measures adopted in mental health services to face the consequences of COVID-19 and shed further light on the impact of the pandemic on the clinical practice of mental health services and on the continuity of care of people with schizophrenia.
