The purpose of this study is to determine the transcranial direct current stimulation (tDCS) cost-utility in the depression therapy.
This is a 3 years medico-economics study with 1 year follow-up period involving patients with 1 or 2 depression treatment(s) failed.
Eligible subject will be randomized in 2 groups, usual care with tDCS cure (arm A) or only usual care (arm B).
Transcranial direct current stimulation is a non-invasive brain neuromodulation technique. tDCS can be a new therapy in depression.
This study focuses on tDCS cost-utility-analysis. Each patient is following during 12 months. Patients are randomized in 2 arms. Arm A usual care with tDCS cure or arm B usual care without tDCS.
Patient in arm A get a initial tDCS cure one week after randomization. If these patients are answering to the treatment, they can have a new cure in case of relapse. This new cure can start from the second month following initial treatment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Usual care and tDCS (Arm A) | Experimental | Arm A patient receives a first tDCS treatment in association with usual care (medication, psychotherapy...). If the patient is responding to tDCS, he can have other tDCS treatments in case of relapse. |
|
| Usual care without tDCS (Arm B) | Active Comparator | Arm B patient receives usual care: medication management and psychotherapy. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| tDCS associated with usual care | Other | A tDCS cure will be given to the group "tDCS", one week after their randomization. This will be done in association with usual care: medication and psychotherapy Parameters: Anodal stimulation on dorso-lateral prefrontal cortex left, 2mA current. Treatment will consist of 15 days with 30 minutes stimulation per day, 5 days a week for 3 weeks. |
| Measure | Description | Time Frame |
|---|---|---|
| Cost-utility ratio, according to collective perspective of tDCS use in depression compared to usual care without active tDCS. | The utility will be measured by : Quality Adjusted Life Year (QALYs) as estimated from responses to the Euroqol-5 Dimensions (EQ-5D) health-related quality of life questionnaire. The questionnaire focuses on 5 dimensions: mobility, personal autonomy, current activities, pain/discomfort and anxiety/depression. For each of these dimensions, 5 answers are possible. The costs will be measured by the addition of the following costs: Drugs dispensing via Health insurance database "National system of information of the French health insurance" (SNIIRAM), hospitalizations, work stoppages and care consumption collected in a declarative patient questionnaire. | 12 months |
| Measure | Description | Time Frame |
|---|---|---|
| Budget impact analysis of spreading the most efficient strategy for using tDCS | Comparison of intervention costs on the study sample and projection of these costs over 5 years, from the health insurance and hospital perspectives | 5 years |

Response is defined as follows: decrease of the MADRS score by at least 50% compared to baseline score. MADRS stands for Montgomery-Asberg Depression Rating Scale. It is used to measure the severity of depressive episodes in patients with mood disorders. The questionnaire includes questions on the following symptoms 1. Apparent sadness 2. Reported sadness 3. Inner tension 4. Reduced sleep 5. Reduced appetite 6. Concentration difficulties 7. Lassitude 8. Inability to feel 9. Pessimistic thoughts 10. Suicidal thoughts and each item yields a score of 0 to 6. The overall score ranges from 0 to 60. A score from 0 to 6 being normal/symptom absent and a score >34 being severe depression. |
| at baseline, at the end of each tDCS cure (for Arm A patients) through study completion (12 months) and at 12 months for all patients |
| Remission rate | Remission rate is defined as follows: MADRS score < 10 (see detailed description of MADRS in outcome 3) | 12 months |
| Relapse-free survival | Number of patients with no relapse. Relapse is defined as follows: MADRS ≥ 20 (see detailed description of MADRS in outcome 3) | 12 months |
| MADRS score | MADRS score (see detailed description of MADRS in outcome 3) | At Baseline, one month, 2 months, 6 months and 12 months. |
| Beck Depression Inventory (BDI) score | The BDI is 13-item multiple-choice self-report inventory, for measuring the severity of depression. The global score is an addition of each item's score and ranges from 0 (minimal depression) to 39 (severe depression). | At Baseline, one month, 2 months, 6 months and 12 months. |
| Clinical Global Impression (CGI) score | The Clinical Global Impression (CGI) rating scales are measures of symptom severity, treatment response and the efficacy of treatments in treatment studies of patients with mental disorders.
