Study population: 110 patients (>18 yrs.) with a depressive episode (unipolar MDD) who will start ECT and 110 patients (>18 yrs.) with a depressive episode (unipolar MDD) who will undergo treatment with antidepressants will be recruited from specialized clinics (academic hospital, general hospital and GGz-institute) and followed-up for one year to gather reliable data on efficacy including relapse rates, cost-effectiveness and quality of life.

Who may be able to join

  • adult patients (>18 years) with a major depressive disorder who will either start with ECT or medication
  • failed response to at least 1 adequate dose-duration trial with antidepressants
  • moderate or severe depression (HDRS-17 >16)

About this study

Prospective observational cohort study to determine cost-effectiveness of ECT compared to medication in the treatment of major depressive disorder (MDD) in the Netherlands.

Read the detailed description

Rationale:

Currently, detailed information on the cost-effectiveness of ECT based on real-world data is lacking, as well as the comparative cost-effectiveness with respect to medication. Reliable information on outcomes of ECT in comparison with antidepressant treatment and its cognitive side-effects is needed for patients and clinicians to make a balanced and shared decision regarding choosing or refraining from ECT.

Objective:

Primary Objective: determine (cost)-effectiveness of ECT compared to medication by determining the impact of treatment for MDD with ECT or TCA on remission rates using a one-year time horizon (trial-based economic evaluation)

Secondary Objective: determine side-effects of ECT compared to medication by determining the impact of treatment with ECT or medication on side-effects and quality of life during a one-year follow-up

Study design: Observational, parallel inception cohort study of patients who will undergo standard clinical care according to current guidelines.

Study population: 110 patients (>18 yrs.) with a depressive episode (unipolar MDD) who will start ECT (ECT group) and 110 patients (>18 yrs.) with a depressive episode (unipolar MDD) who will undergo treatment with antidepressants will be recruited from specialized clinics (academic hospital, general hospital and GGz-institute) and followed-up for one year to gather reliable data on efficacy including relapse rates, cost-effectiveness, quality of life and cognitive functioning.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effectiveness of treatment as measured by reduction on HDRS-17

    Depression severity measured by The Hamilton Depression Rating Scale 17 item version (HDRS-17)

    Measured: change from baseline at 3 months, 6 months and 12 months

Secondary outcomes (7)
  1. Cost-effectiveness as measured with The Trimbos Institute and iMTA Cost questionnaire for Psychiatry (TiC-P)

    Cost-effectiveness as measured with The Trimbos Institute and iMTA Cost questionnaire for Psychiatry (TiC-P)

    Measured: change from baseline at 3 months, 6 months and 12 months

  2. Quality of life as measured with the EuroQol-5D (EQ-5D-5L)

    Quality of life as measured with the EuroQol-5D (EQ-5D-5L)

    Measured: change from baseline at 3 months, 6 months and 12 months

  3. Cognitive functioning as measured by Montreal Cognitive Assesment (MoCA)

    Cognitive functioning as measured by Montreal Cognitive Assesment (MoCA)

    Measured: change from baseline at 3 months, 6 months and 12 months

  4. COLUMBIA UNIVERSITY - AUTOBIOGRAPHICAL MEMORY INTERVIEW SHORT FORM (CU-AMI-SF)

    Measured: change from baseline at 3 months, 6 months and 12 months

  5. Subjective Assessment of Memory Impairment (SAMI)

    Subjective Assessment of Memory Impairment (SAMI)

    Measured: change from baseline at 3 months, 6 months and 12 months

  6. 15 words test (15WT)

    (15WT; Saan \& Deelman, 1986)

    Measured: change from baseline at 3 months, 6 months and 12 months

  7. Verbal fluency test (e.g., Lezak et al., 2012).

    It typically consists of two tasks: category fluency (sometimes called semantic fluency; Benton, 1968) and letter fluency (sometimes called phonemic fluency; Newcombe, 1969). participants are given 1 min to produce as many unique words as possible within a semantic category (category fluency) or starting with a given letter (letter fluency).

    Measured: change from baseline at 3 months, 6 months and 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Depressive Disorder, Major, run by Radboud University Medical Center at 2 sites in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 21 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effectiveness of treatment as measured by reduction on HDRS-17 (time frame: change from baseline at 3 months, 6 months and 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Apr 2026.
