Objectives: Electroconvulsive therapy (ECT) is an effective and safe treatment of certain severe mental disorders, but there are some barriers to the implementation of continuation/maintenance ECT courses in some cases. Repeated difficulties in achieving intravenous access before each session may contribute to premature ECT discontinuation. The placement of a totally implantable venous-access device (TIVAD) could be an alternative to overcome these difficulties in certain subjects.
Methods: For the present study we retrospectively identified all patients treated with continuation/maintenance ECT in our facilities during a 13-year period to which a TIVAD was implanted, paying attention to specific factors related to clinical characteristics, treatment course, and ECT technique.
Results: We identified a TIVAD in 16 (3.33%) of 481 patients receiving ECT in our unit, of whom 87.5% were female. Half of the cases met the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) criteria for schizophrenia, 6 for bipolar disorder, and 2 for major depression disorder. Age of the study cases ranged from 17 to 87 years. A total of 1957 ECT sessions were registered in this group of cases during the observation period. Patients had undergone a mean of 124.06 ± 132.41 ECT sessions before the TIVAD was implanted, with the device mean time of utilization being 5.39 ± 3.46 years. In 2 cases, the device was removed after ECT discontinuation. Few incidents associated with the implantation and operation of the TIVAD were registered, comparable to the use of this device in other clinical contexts.
Conclusions: This case series suggest that a TIVAD placement can be an effective and safe solution for patients in continuation/maintenance ECT courses with difficult intravenous access. Future studies will need to carefully monitor the benefit and the potential complications of TIVAD placement in patients undergoing continuation/maintenance ECT programs.

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.
Objective: There are few studies that examine the effectiveness of Continuation/Maintenance Electroconvulsive Therapy (C/M-ECT) in schizophrenia, despite the documented effectiveness of acute ECT treatment. We aimed to investigate the clinical effectiveness of C/M-ECT for in-patients with Schizophrenia in a naturalistic setting. We examined the medical records of 46 in-patients who were diagnosed with Schizophrenia and had received C/M-ECT belonging to non-acute extended care service in a public psychiatry hospital in Sydney, Australia.

Effect of Continuation-Maintenance Electroconvulsive Therapy on Hospitalization: A Retrospective Mirror-Image Study.
Neuropsychiatr Dis Treat
June 2023
Department of Psychiatry, Faculty of Medicine, Ramathibodi Hospital, Mahidol University, Bangkok, Thailand.
Objective: To examine the effect of continuation-maintenance electroconvulsive therapy (ECT) on psychiatric hospitalization in Thai patients.
Methods: This retrospective mirror-image study reviewed medical records of Thai patients who received continuation-maintenance ECT at Ramathibodi Hospital, Bangkok, between September 2013 and December 2022. The initiation of continuation-maintenance ECT served as the index event, establishing pre-initiation and post-initiation periods.

Background: The transdiagnostic effect of continuation/maintenance ECT (CM-ECT) across mood and psychotic disorders on hospital psychiatric readmission risk and total direct cost remains unclear.
Methods: A naturalistic retrospective analysis of 540 patients who received inpatient acute ECT treatment from May 2017 to Mar 2021 in a tertiary psychiatric institution. Patients were assessed with validated clinical rating scales pre-ECT and after the first 6 treatments of a course of inpatient acute ECT.
