A Study Based on the French National Health Insurance Database in Participants With Psychotic Disorders

Inclusion Criteria: * At least one discharge for psychiatric hospitalization with a diagnosis of a psychotic disorder between January 1, 2014 and December 31, 2020. * At least one long-term disease record (LTD), (which is a French administrative status allowing the full reimbursement of the cost of a chronic pathology) with a diagnosis of a psychotic disorder between January 1, 2014 and December 31, 2020. * Age of 18 years or older at index date (first date found in the previous conditions). Exclusion Criteria: • Due to data management constraint, the participants with multiple or temporary identifiers in the database (indistinguishable in database) will be excluded. This happens with twins or migrants, for example.
