Brief Summary

Severe depression is devastating for those affected and is often associated with significant risk of suicide. Electroconvulsive therapy (ECT) is a highly effective acute treatment for severe depression, but its use and acceptability are limited by cognitive side effects. Of these, retrograde memory loss is most concerning, and can be long-term. The introduction of ultrabrief right unilateral (UBRUL) ECT into clinical practice has been an important step in reducing the risk of memory impairment, but significant deficits still occur. A new form of UBRUL ECT which utilises a Frontoparietal electrode placement represents a further development. Preliminary data suggest that Frontoparietal UBRUL has good efficacy and less cognitive side effects than UBRUL given using the conventional Temporoparietal electrode placement. Designed as a pivotal trial, this protocol will be the first RCT comparing these two forms of ECT, producing the rigorous efficacy and safety data required to change clinical practice/policy. This is a multicentre, parallel group RCT with 1:1 allocation ratio between Frontoparietal (intervention) and Temporoparietal (comparator) forms of UBRUL ECT. Participation will involve receiving randomised acute ECT under blinded conditions during the randomised acute treatment period (typically around 4 weeks), then completion of a 24-week follow-up period which commences after the cessation of all acute ECT. The study protocol aims to provide 12 randomised acute ECT treatments, though the number of treatments (and hence the length of the randomised acute treatment period) can be adjusted by the participant's own treating/admitting psychiatrist according to their clinical judgement.

Outcome Measures

Primary Outcomes (1)

  • Change in Depressive Symptoms as Assessed by Hamilton Rating Scale for Depression-17

    The Hamilton Rating Scale for Depression-17 has a range of 0-52. Lower scores represent mild depression to no depression at all.

    From baseline to end of randomized acute treatment (typically 4 weeks)

Secondary Outcomes (13)

  • Change in Depressive Symptoms as Assessed by Hamilton Rating Scale for Depression-17

    From end of acute ECT treatment up to 24-week follow-up

  • Autobiographical Memory Interview-Short Form (AMI-SF) Consistency Scores

    From Baseline to end of randomized acute treatment (typically 4 weeks)

  • Clinical Global Impression-Severity (CGI-S)

    From baseline to end of randomized acute treatment (typically 4 weeks)

  • Clinical Global Impression-Improvement (CGI-I)

    Through the randomized acute ECT treatment period (typically 4 weeks)

  • Suicidality score

    From baseline to end of randomized acute treatment (typically 4 weeks)

  • +8 more secondary outcomes

Study Arms (2)

Frontoparietal ECT Group

EXPERIMENTAL

Participants will receive ultrabrief right unilateral ECT with a frontoparietal placement of ECT electrodes.

Procedure: Frontoparietal Ultrabrief Right Unilateral (UBRUL-FP) electroconvulsive therapy

Temporoparietal ECT Group

ACTIVE COMPARATOR

Participants will receive ultrabrief right unilateral ECT with the conventional temporoparietal placement of ECT electrodes.

Procedure: Temporoparietal Ultrabrief Right Unilateral (UBRUL-TP) electroconvulsive therapy

Interventions

UBRUL-TP is the standard form of ultrabrief right unilateral ECT, using the conventional temporoparietal (d'Elia) electrode placement, where the anterior electrode is placed over the right temporal lobe. UBRUL-TP will be delivered using standard ECT devices.

Temporoparietal ECT Group

UBRUL-FP involves ultrabrief right unilateral ECT delivered using a novel frontoparietal montage, where the anterior electrode is shifted frontally to a position above the midpoint of the right eye to avoid temporal lobe stimulation (and reduce memory side effects). UBRUL-FP will be delivered using standard ECT devices.
