Objectives: To retrospectively analyse patients receiving maintenance Electroconvulsive therapy (ECT), patterns of ECT treatment administration and impact on hospitalisation before and during treatment, in a single New Zealand District Health Board catchment. We also asked other District Health Boards in New Zealand for annual data on their use of maintenance ECT.
Methods: Regional analysis: retrospective analysis of patient-level data over 9 years. National analysis: survey of maintenance ECT/year.
Results: Regionally, 14 patients received maintenance ECT over 9 years. Patients were 50% male, with mean age 59 years, and principal diagnoses included schizophrenia, bipolar disorder and major depressive disorder. The time between ECT treatments tended to be shorter for patients with schizophrenia compared with those with mood disorders. Duration of time in hospital during maintenance ECT, compared with pre-ECT, was reduced by 52% for all patients, with greater reductions for patients with mood disorders compared with those with schizophrenia. Nationally, 19.7% of all ECT treatments in New Zealand (range 4-57%) were for maintenance treatment.
Discussion: Regional and national use patterns of maintenance ECT in New Zealand resemble those reported internationally. The RANZCP section of neurostimulation is planning ECT standards which would assist with ensuring coherence and quality of High-dose contrast-enhanced computed tomography/modified electroconvulsive therapy practice in New Zealand.

Practice of Electroconvulsive Therapy in Catalonia in 2022: Results From a Large Cross-Sectional Survey.
J ECT

Bipolar and Depressive Disorders Unit, Hospital Clínic de Barcelona, Barcelona, Catalunya, Spain.
Introduction: The practice of electroconvulsive therapy (ECT) exhibits variability across various domains, both between regions, and between centers within the same region. The ECT Working Group of the Catalan Society of Psychiatry conducted a comprehensive survey in Catalonia, Spain, to assess the current status of those variables essential in the clinical practice of ECT.
Materials And Methods: The survey comprised 50 items, including various question types such as multiple-choice, numerical response, and open-ended questions.
Tardive seizure after electroconvulsive therapy: Prevalence and associated factors.

University of Tunis El Manar, Faculty of Medicine of Tunis, Department of Psychiatry D, Razi Hospital, Manouba, Tunisia.
Article Synopsis
- Tardive seizures are rare, spontaneous seizures that can occur after electroconvulsive therapy (ECT), potentially leading to severe complications like status epilepticus, and the risk factors and management are not well-defined.
- This study aimed to explore the prevalence of tardive seizures in patients undergoing ECT at Razi Hospital over seven years and to identify factors linked to this occurrence.
- The retrospective analysis included 1,931 ECT sessions from 157 patients, revealing a 4.45% incidence of tardive seizures among patients and a prevalence rate of 0.57% for individual sessions.
Relapse Following Electroconvulsive Therapy for Schizophrenia: A Systematic Review and Meta-analysis.
Schizophr Bull
October 2024
Department of Neuropsychiatry, Faculty of Medicine, Kansai Medical University, Osaka, 570-8506, Japan.
Article Synopsis
- There is limited evidence on schizophrenia relapse following electroconvulsive therapy (ECT), prompting a systematic review to gather more data on this issue.
- The study analyzed 29 research papers, finding that relapse rates for schizophrenia after acute ECT were 24% at 3 months, increasing to 55% by 24 months.
- Adding maintenance ECT along with antipsychotics significantly lowered the relapse rate to 20% at the 6-month mark, indicating the need for further research to improve treatment strategies post-ECT.

Importance: Large-scale evidence for the efficacy of continuation and maintenance electroconvulsive therapy (c/mECT) is lacking.
Objective: To provide an exhaustive and naturalistic insight into the real-world outcomes and the cost-effectiveness of c/mECT in a large dataset.
Design, Setting, And Participants: This cohort study included all patients in the Danish National Patient Registry who initiated treatment with ECT from 2003 through 2022.
