Study typeObservational study
Brief description of the studyDepression is a common mental illness, which concerns 4.8% of the French population and is associated with a high psychological, social and economic burden. In 15 to 30% of the depressive episodes, the depression becomes resistant to treatment but these estimates are not accurate since the notion of treatment-resistant depression (TDR) is difficult to define precisely. Conventionally, TRD involves depression that fails to improve adequately after the use of 2 AD (whether or not they are from different pharmacological class) at doses and durations that would normally be effective, administered to a patient believed to be adherent (3). Patients suffering from TRD experience a disproportionate burden of illness with significant impairment, increased morbidity, and higher economic costs than those of a treatment responsive depression case (4). The global epidemiological situation and the clinical characteristics of TDR are thus poorly understood and require further study, especially in France. With the development of a new medication for the treatment of TRD, Janssen-France requests that the Bordeaux PharmacoEpi (BPE) platform, CIC Bordeaux CIC1401 of Bordeaux University, carries out a study in France to estimate the frequency of, the risk factors and the costs for TRD using the SNIIRAM nation-wide claims and hospital database.
