Detailed Description
Description of the use of Quetiapine Extended Release (XR) in real-life practice in France
Arms, Groups and Cohorts
- Main study population
- All eligible patients receiving Quetiapine XR for the first time in the inclusion period regardless the diagnosed disease or the patients’ age. Patients aged 18 years and over and diagnosed with bipolar disorder or schizophrenia according to DSM-IV criteria will be followed during 12 months.
- Schizophrenia SoC sample
- Patients would have to be prescribed for the first time with a new (not used during the preceding 3 months) atypical antipsychotic other than Quetiapine XR (irrespective this new atypical antipsychotic is preceded or not by another atypical antipsychotic).
- Bipolar SoC sample
- Patients would have to be prescribed a new (not used during the preceding 3 months) antidepressant [N06A], antipsychotic (other than Quetiapine XR) [N05A] or mood stabilizer (including lithium [N05AN], valproate [N03AG01], and lamotrigine [N03AX09].
Clinical Trial Outcome Measures
Primary Measures
- Descriptive analysis of variables related with how the drug is prescribed and used by the patient.
- Time Frame: At inclusion
- Variables related with how the drug is prescribed and used by the patient [doses in mg/day, titration (yes/no), time of administration (morning/middle of the day/afternoon/evening), concomitant treatments] are going to be described.
- Description of patient’s socio-demographics profile.
- Time Frame: At inclusion
- Age, gender, educational and professional status, co-habitation are going to be described.
- Descriptive analysis of medical history.
- Time Frame: At inclusion
- Diagnosis, family history of psychiatric disorders, number of suicidal attempts within the last 12 months, co-morbidities, treatments received during the last 12 months, laboratory and exam data will be included in the description.
- Severity of the disease measured by Clinical Global Impressions Scale – Severity (CGI-S).
- Time Frame: At inclusion
- The Clinical Global Impressions Scale – Severity (CGI-S) assesses the clinician’s impression of the current state of the patient’s illness. The following scores can be given: 1=normal, not at all ill, 2=borderline mentally ill, 3=mildly ill, 4=moderately ill, 5=markedly ill, 6=severely ill, and 7=among the most extremely ill patients.
Secondary Measures
- Change in Clinical Global Impressions Scale – Severity (CGI-S) during the treatment.
- Time Frame: From baseline to 12 months
- The Clinical Global Impressions Scale – Severity (CGI-S) assesses the clinician’s impression of the current state of the patient’s illness. The following scores can be given: 1=normal, not at all ill, 2=borderline mentally ill, 3=mildly ill, 4=moderately ill, 5=markedly ill, 6=severely ill, and 7=among the most extremely ill patients.
- Quetiapine XR and concomitant treatment stop, stop date, reasons to stop, restart, restart date, reasons to restart.

- Description of patterns of healthcare management resource use related with psychiatric disorders under investigation.
- Time Frame: From baseline to 12 months
- Change in Body Mass Index (BMI).
- Time Frame: From baseline to 12 months
- Laboratory tests- cholesterol.
- Time Frame: From baseline to 12 months

- Descriptive analysis of all adverse events.
- Time Frame: From baseline to 12 months
- Relapses (only for the schizophrenia subpopulation).
- Time Frame: From baseline to 12 months
- New psychiatric hospitalisation, deterioration of the CGI-S (Clinical Global Impressions Scale – Severity) by at least 3 points for a baseline score of 1, at least 2 points for a baseline score of 2 or 3, at least 1 point for a baseline score of 4.
- Laboratory tests- glycemia.
- Time Frame: From baseline to 12 months
- Blood test- glycemia.
