- 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.

Group Intervention Description Temporoparietal ECT Group Temporoparietal Ultrabrief Right Unilateral (UBRUL-TP) electroconvulsive therapy Participants will receive ultrabrief right unilateral ECT with the conventional temporoparietal placement of ECT electrodes.

- Primary Outcome Measures
Name Time Method Change in Depressive Symptoms as Assessed by Hamilton Rating Scale for Depression-17 From baseline to end of randomized acute treatment (typically 4 weeks) The Hamilton Rating Scale for Depression-17 has a range of 0-52. Lower scores represent mild depression to no depression at all.
- Secondary Outcome Measures
Name Time Method Suicidality score From baseline to end of randomized acute treatment (typically 4 weeks) Assessed by examining scores on item 3 (suicidality) of the Hamilton Rating Scale for Depression (which range from 0 to 4, where higher scores indicate more severe and/or persistent suicidality) and scores on the suicidal ideation subscale of the Columbia
Post ECT reorientation time After ECT sessions 3 and 6, which typically occur at the end of week 1 and week 2 in the randomised acute treatment phase. Post ECT reorientation time is the time taken to recover orientation immediately after ECT in randomised treatment phase.
Change in mean neuropsychological function From baseline to end of randomized acute treatment (typically 4 weeks) Assessed by a cognitive test battery.
Number of randomized ECT treatments given over the Acute Study Treatment Phase (RCT) From baseline to End of Randomized Acute Treatment (typically 4 weeks) Number of randomized acute ECT treatments received by participants during the Acute Study Treatment Phase (RCT), compared between the groups.
Mental Health Questionnaire-14 (MHQ-14) From baseline to end of randomized acute treatment (typically 4 weeks) The Mental Health Questionnaire-14 is a self-report quality of life instrument consisting of the mental health component of the Medical Outcomes Study questionnaire. This patient self-report measure contains 14 items in total, addressing symptoms of fatigue, anxiety and depression, and the impact of these symptoms on functioning. Scores on this measure range from 0 to 100, where higher scores indicate better quality of life.
Occurrence of adverse events and serious adverse events From baseline and up to 24-week follow-up Occurrence of adverse events (AEs) and serious adverse events (SAEs) compared between the groups, based on treating them as binary outcomes (no/yes, e.g., whether participants experienced any given side effect/adverse event at least once) and as count outcomes (number of occurrences).
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 The Hamilton Rating Scale for Depression-17 has a range of 0-52. Lower scores represent mild depression to no depression at all.
Clinical Global Impression-Improvement (CGI-I) Through the randomized acute ECT treatment period (typically 4 weeks) The Clinical Global Impression-Improvement is a measure where a clinician assesses how much the patient's illness has improved or worsened in comparison to baseline. The "improved" version being used in this trial (Kadouri, Corruble \& Falissard, 2007) is a 13-point scale with ratings which range from 6 ('ideal improvement') to -6 (maximum deterioration).
Autobiographical Memory Interview-Short Form (AMI-SF) Consistency Scores From Baseline to end of randomized acute treatment (typically 4 weeks) In the Autobiographical Memory Interview-Short Form, participants are graded on the consistency of their answers between baseline and subsequent time-points. The maximum consistency score is 100 percent, with lower percentages representing increasing inconsistency in retrospective autobiographical memory function.
Clinical Global Impression-Severity (CGI-S) From baseline to end of randomized acute treatment (typically 4 weeks) The Clinical Global Impression-Severity measure is a 7-point scale where a clinician rates the severity of a patient's illness in comparison to the clinician's experience with patients who have the same diagnosis. The ratings range from 1 indicating normal, not at all ill to 7 suggesting they are among the most extremely ill patients.
Number of responders From baseline to End of Randomized Acute Treatment (typically 4 weeks) Response is defined as a 50 percent reduction in depression severity from baseline, assessed using the Hamilton Rating Scale for Depression-17
Number of remitters From baseline to end of randomized acute treatment (typically 4 weeks) Remission is defined as a score of ≤ 7 on the Hamilton Rating Scale for Depression-17.
Number of participants switched from randomized treatment to another form of acute ECT After at least 8 randomized ECT treatments (typically after 3 weeks). Number of participants switched from randomized treatment to another form of acute ECT after receiving at least 8 randomized ECT.
