Factors associated with direct health care costs in schizophrenia: Results from the FACE-SZ French dataset

International audienceINTRODUCTION: There is a lack of data on health care consumption of patients suffering from schizophrenia, as well as on the related health care costs. Factors associated with health care costs have not been widely studied, whereas knowledge on this topic would allow identifying risk factors and delineating strategies to improve patients' health and follow-up, likely to also decrease health care costs. The aim of this study was to estimate the average direct health care cost of patients with schizophrenia in France and to identify the factors associated with this cost. METHODS: The study population included patients with schizophrenia enrolled in the FondaMental Advanced Centers of Expertise for Schizophrenia cohort. We accounted for the costs directly related to the treatment of schizophrenia. They included the costs of hospitalizations (full- and part-time), psychiatric ambulatory consultations and medications. We studied three categories of factors potentially associated with direct health care costs: demographic, socioeconomic and clinical characteristics. RESULTS: Three hundred and ninety five patients with schizophrenia were included. The mean (median) annual direct health care cost per patient amounted to \texteuro14,995 (\texteuro3,435). A lower level of functioning and being single were associated with a higher cost. A significant association between the expert center of inclusion and the direct health care cost of schizophrenia was also highlighted. CONCLUSION: Our results highlighted the significant cost of schizophrenia and suggest that improvement in patient care, based on well-validated targeted therapeutic interventions such as psycho-education and cognitive rehabilitation, could reduce worsening in symptom severity and therefore decrease health care costs
