ABSTRACT
OBJECTIVES: We aimed to assess the impact of the COVID-19 crisis on the occurrence of new hospital admissions for cases of psychosis in France. METHOD: We conducted a retrospective observational study from the French national PMSI database. We included patients hospitalized between 2018 and 2020 with a principal diagnosis of schizophrenia or delusional disorder with no history of psychosis in the previous 10 years. In total, we included 77,172 inpatients at crisis centers and/or in full-time hospitalization at 465 French hospitals. We assessed the number of inpatients during the year of the Covid crisis (2020) and the two years prior (2018, 2019). RESULTS: The number of inpatients in full-time hospitalization decreased gradually from 2018 to 2020 by 10.6%. This downward trend was observed in all age groups. In contrast, in crisis centers the number of inpatients increased by 13.4% between 2019 and 2020, while a 7.6% decrease was seen between 2018 and 2019. The greatest increase was observed in the 31-60-year age category, and particularly amongst 46-60-year-olds, i.e. 38.0%. CONCLUSION: The COVID-19 crisis was associated with an increase in the number of inpatients with a new episode of psychosis in crisis centers but not in full-time hospitalization. The profile of patients in crisis centers was different from that seen in preceding years and included more middle-to-late age adults. Particular attention should be given to this category of patients in the crisis environment to prevent the occurrence of new cases of psychosis in France.
