Empirical ratio of the combined use of S-ketamine and propofol in electroconvulsive therapy and its impact on seizure quality.

Electroconvulsive therapy (ECT) is an effective treatment for depressive disorders. In certain cases, ECT-associated anaesthesia can be improved by the use of ketofol (i.e., S-ketamine + propofol). We aimed to evaluate the empirical mixing ratio of ketofol in these cases for better clinical implementation. We retrospectively investigated n = 52 patients who received 919 ECT sessions with S-ketamine plus propofol as anaesthetic agents. Several anaesthesia and ECT-related parameters including doses of S-ketamine and propofol were analysed. The mean empirically determined S-ketamine/propofol ratio was 1.38 (SD ± 0.57) for 919 individual ECT sessions and 1.52 (SD ± 0.62) for 52 patients, respectively. The mean relative dose was 0.72 (± 0.18) mg/kg S-ketamine and 0.54 (± 0.21) mg/kg propofol. Higher propofol dose was associated with poorer seizure quality. Seizure quality and time in recovery room were significantly influenced by age. Ketofol could be an option to exploit the advantageous qualities of S-ketamine and propofol, if both doses are reduced compared with single use of S-ketamine or propofol. Patients with poor seizure quality may benefit from lower propofol doses, which are applicable by the addition of ketamine. An empirically determined mixing ratio in favour of ketamine turned out to be preferable in a clinical setting. Recovery time was primarily prolonged by higher age rather than by ketamine dose, which had previously often been associated with a prolonged monitoring time in the recovery room. These new findings could improve electroconvulsive therapy and should be replicated in a prospective manner.

Last Resort Interventions?: A Qualitative Study of Psychiatrists' Experience with and Views on Psychiatric Electroceutical Interventions.

Psychiatrists play an important role in providing access to psychiatric electrical interventions (PEIs) such as electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS). As such, their views on these procedures likely influence whether they refer or provide these types of treatments for their clinically depressed patients. Despite this, scholars have too infrequently examined psychiatrists' views about specific PEIs and have not yet examined their views across different PEIs. To gain insight into psychiatrists' views about PEIs, we conducted a qualitative study based on semi-structured interviews with 16 psychiatrists in Michigan. The majority of psychiatrists had a positive attitude towards PEIs in general. One-third reported cautionary attitudes towards PEIs; they did not reject the interventions but were skeptical of their effectiveness or felt they needed further development. The majority of psychiatrists consider ECT and TMS to be viable therapies that they would discuss with their patients after several failed medication trials. There was a lack of knowledge about surgical PEIs, such as deep brain stimulation. This study provides insights into how psychiatrists perceive PEIs. While broadly positive attitudes exist, this research highlights certain challenges, particularly lack of knowledge and ambiguity about the use of PEIs.

Electroconvulsive Therapy Practice Changes in Older Individuals Due to COVID-19: Expert Consensus Statement.

The ubiquitous coronavirus 2019 (COVID-19) pandemic has required healthcare providers across all disciplines to rapidly adapt to public health guidelines to reduce risk while maintaining quality of care. Electroconvulsive therapy (ECT), which involves an aerosol-generating procedure from manual ventilation with a bag mask valve while under anesthesia, has undergone drastic practice changes in order to minimize disruption of treatment in the midst of COVID-19. In this paper, we provide a consensus statement on the clinical practice changes in ECT specific to older adults based on expert group discussions of ECT practitioners across the country and a systematic review of the literature. There is a universal consensus that ECT is an essential treatment of severe mental illness. In addition, there is a clear consensus on what modifications are imperative to ensure continued delivery of ECT in a manner that is safe for patients and staff, while maintaining the viability of ECT services. Approaches to modifications in ECT to address infection control, altered ECT procedures, and adjusting ECT operations are almost uniform across the globe. With modified ECT procedures, it is possible to continue to meet the needs of older patients while mitigating risk of transmission to this vulnerable population.

Characterization of the Quality of Electroconvulsive Therapy Among Older Medicare Beneficiaries.

BACKGROUND: Electroconvulsive therapy (ECT) is an important therapy for treatment-resistant depression and is especially effective for elderly individuals with depression. This is the first US nationally representative description of ECT in the elderly. METHODS: Using 2014-2015 Medicare claims data, we compared elderly individuals with major depressive disorder (using ICD-9 and ICD-10 codes) who received ECT with those who did not on demographic and clinical measures. We characterized treatment patterns by setting and the proportion of individuals receiving index and continuation/maintenance courses, subtherapeutic courses of ECT, and post-ECT follow-up care. RESULTS: Of all Medicare beneficiaries aged 65 years and older diagnosed with depression in 2014-2015, 7,817 (0.41%) received 1 or more ECT sessions. Compared to the general population of elderly Medicare beneficiaries with depression, recipients of ECT were slightly younger and more likely to be male, non-Hispanic, and white and live in a zip code with a higher median income. Among those who received any ECT, 33.7% received < 5 total treatments. Of those who received an index ECT treatment, 33.7% received a continuation/maintenance course of ECT, while 60.9% received some form of post-ECT follow-up treatment (additional ECT or new psychotropic medication). Receipt of psychotherapy was the strongest predictor of those who received ≥ 5 ECT treatments (adjusted odds ratio = 1.43; 95% CI, 1.22 to 1.67). CONCLUSIONS: Despite substantial evidence of efficacy, ECT use remains rare among elderly patients with depression. Findings suggest a potential need for efforts to increase the proportion of patients receiving adequate courses of ECT and evidence-based post-ECT follow-up care.

[Recommendations for a gradual and controlled resumption of electroconvulsive therapy in France during the period of lifting of the containment and of the COVID-19 pandemic linked to SARS-CoV-2]. / Recommandations pour une reprise progressive et contrôlée de l'électroconvulsivothérapie en France en période de levée du confinement et de pandémie COVID-19 liée au SARS-CoV-2.

The COVID-19 pandemic has had major consequences for the organization of care. In France and around the world, centers practicing electroconvulsive therapy (ECT) have seen their activity decrease, or even stop for many reasons. In this context, maintaining or resuming this essential therapeutic activity for many patients suffering from psychiatric disorders requires material, human and logistical adaptations that should be supervised. The objective of this collective and national work is to offer simple recommendations that can be applied immediately by any healthcare establishment, public or private, practicing ECT. They are the result of feedback from multiprofessional and inter-establishment experiences. Declined in three stages, these recommendations are accompanied by a practical sheet which describes in detail the necessary conditions and prerequisites for any resumption of ECT activity.

Modified Anesthesia Protocol for Electroconvulsive Therapy Permits Reduction in Aerosol-Generating Bag-Mask Ventilation during the COVID-19 Pandemic.

INTRODUCTION: Electroconvulsive therapy (ECT) is a critical procedure in psychiatric treatment, but as typically delivered involves the use of bag-mask ventilation (BMV), which during the COVID-19 pandemic exposes patients and treatment staff to potentially infectious aerosols. OBJECTIVE: To demonstrate the utility of a modified anesthesia protocol for ECT utilizing preoxygenation by facemask and withholding the use of BMV for only those patients who desaturate during the apneic period. METHODS: This chart review study analyzes patients who were treated with ECT using both the traditional and modified anesthesia protocols. RESULTS: A total of 106 patients were analyzed, of whom 51 (48.1%) required BMV using the new protocol. Of clinical factors, only patient BMI was significantly associated with the requirement for BMV. Mean seizure duration reduced from 52.0 ± 22.4 to 46.6 ± 17.1 s, but seizure duration was adequate in all cases. No acute physical, respiratory, or psychiatric complications occurred during treatment. CONCLUSIONS: A modified anesthesia protocol reduces the use of BMV by more than 50%, while retaining adequate seizure duration.

[Electroconvulsive therapy in combination with psychotropic and non-psychotropic pharmacological treatments: Review of the literature and practical recommendations]. / Électroconvulsivothérapie en association avec des traitements pharmacologiques psychotropes et non psychotropes : revue de la littérature et recommandations pratiques.

CONTEXT: Electro-convulsive therapy (ECT) is the most effective treatment for treatment resistant mood disorders and catatonia. ECT also appears to be an effective treatment in combination with clozapine in the context of treatment resistant schizophrenia spectrum disorders. Although increasingly codified (guidelines on indications, contraindications, methods of implementation), the practice of ECT still lacks consensual protocols. The concomitant use of psychotropic and/or non-psychotropic medication is a common situation when ECT treatment is considered. To our knowledge, there is to date no summary of studies or case reports in France, nor any proposal for guidelines concerning the management of medication of the patient to whom ECT sessions are offered. Indeed, several particularities must be considered. This article proposes to specify for each pharmacological class the possible interaction between ECT and medication. A first section of this article will be devoted to non-psychotropic treatments, and a second section to psychotropic treatments. A practical summary table is also provided. METHOD: A review of the literature was conducted including all articles published prior to January 2019 referenced in Pub Med database, combining research with Medical Subject Headings "Electroconvulsive Therapy" and each following pharmacological class: "Cardiovascular Agents" "Bronchodilator Agents" "Bronchoconstrictor Agents" "Theophylline" "Anticoagulants" "Hypoglycemic Agents" "Insulin" "Potassium" "Benzodiazepines" "Valproic Acid" "Carbamazepine" "Lamotrigine" "Lithium" "Antidepressive Agents" "Antipsychotic Agents". RESULTS: After reading the titles, abstracts and whole articles, then searching for additional articles in the references, 50 articles were selected. A summary table summarizing the main risks and proposing a course of action has been produced. DISCUSSION: It is essential to take into account the specificity and the different physiological mechanisms involved in the ECT treatment in order to adjust the associated pharmacological treatments. The prescription for each molecule should be reviewed when ECT treatment is initiated.

Competency by Design for Electroconvulsive Therapy in Psychiatry Postgraduate Training: Face and Content Validation Study.

INTRODUCTION: Psychiatry is in the process of shifting curricula in postgraduate training to a competency-by-design approach. One core aspect of postgraduate psychiatry training is the knowledge and practice of electroconvulsive therapy (ECT). The aim of this study was to develop and validate the corresponding set of competencies that need to be developed during postgraduate training in psychiatry. METHODS: This study involves the proposal of a set of competencies by an ECT curriculum committee from the University Department of Psychiatry, based on the competency-by-design principles, followed by a modified Delphi process, to reach expert consensus on the proposed, modified, and added competencies. RESULTS: Six ECT experts meeting the preset criteria were recruited to the study from 6 academic centers across Canada and participated in the 2 Delphi rounds. Thirty-one competencies were proposed in the first round. Twenty-three proceeded to the second round by meeting 80% agreement on a score of ≥4 using a 5-point Likert scale. Three competencies required rewording based on qualitative feedback; accordingly, 10 new competencies were suggested. Thirty-five competencies were rated by experts and reached the threshold of agreement and rating. Cronbach α increased from 0.89 after the first round to 0.95 after the second iteration. DISCUSSION: Consensus was generated on 35 competencies that need to be achieved during postgraduate training in psychiatry. These competencies can serve as the basis for developing ECT curricula in postgraduate psychiatry training. The method used is feasible and can be adopted for the development of other competencies and curricula in psychiatry and other medical fields.

Intraclass correlations of seizure duration by wavelet transform, sample entropy, and visual determination in electroconvulsive therapy.

Although electroconvulsive therapy seizure duration has been shown to have limited relevance to efficacy, seizure duration remains important for clinically valid stimulus efficiency. There has been no report on seizure duration using sample entropy with Thymatron (Somatics, Inc), which is widely used in Japan. Furthermore, wavelet transform analysis is also suitable for a seizure because of the wide range of dominant frequencies. Therefore, in this study with Thymatron, the intraclass correlations of seizure duration determined by sample entropy, wavelet transform, and visual determination were investigated to determine whether these methods were applicable for clinical use. Wavelet transform, sample entropy, and the human rater had high intraclass correlations for seizure duration. The present results indicate that wavelet transform and sample entropy can be useful in the clinical electroconvulsive therapy setting, and they may also be suitable for clinical research into the mechanisms of the generalized tonic-clonic seizures related to the efficacy of electroconvulsive therapy.

Evidence-Based Education for Perianesthesia RNs to Increase Knowledge and Change Attitudes of Electroconvulsive Therapy.

PURPOSE: To increase perianesthesia registered nurses (RNs') knowledge and change attitudes of electroconvulsive therapy (ECT). DESIGN: A pretest/post-test design was used. METHODS: An interprofessional team collaborated in the development of a 1-hour teaching session, which included PowerPoint presentation, case studies, and online resources. The education was offered four times from December 2017 to April 2018. Data were collected on self-reported learning outcomes and the Questionnaire on Attitudes and Knowledge of ECT. FINDINGS: After the education, increased knowledge was reported. RNs (n = 25) were more likely to recommend ECT as a treatment option (P = .013) and believed that psychiatrists take other health care providers' views into account (P = .023). They were also more likely to believe that ECT should not be used as a last resort (P = .022) and should not be banned (P = .025). CONCLUSIONS: Self-reported knowledge increased, and some of the RNs' attitudes toward ECT changed after education.

Electroconvulsive Therapy in Children and Adolescents: Clinical Indications and Special Considerations.

Electroconvulsive therapy (ECT) is a well-tolerated, well-established, and efficacious treatment in adults, particularly in the setting of severe mood and psychotic disorders. In children and adolescents, however, ECT is infrequently administered and likely underutilized. Results from older studies evaluating the utility of ECT in children and adolescents were mixed, but recent studies have supported ECT treatment success in these patients, with particularly high response rates for treating depression. In this Perspectives, we discuss the current clinical indications for ECT in managing mood and psychotic disorders in children and adolescents. We then review the pretreatment evaluation and management of patients receiving ECT and examine the efficacy of ECT for those indications. We also address issues unique to children and adolescents, versus adults, that need to be considered when determining whether treatment with ECT is appropriate for a patient in this age group. Included in this context are the distinct side-effect profile in children and adolescents, ethical issues regarding informed consent, incorporating the child into the decision-making process when developmentally appropriate, and the need to take into account differing state jurisdictional processes.

Etomidate improves seizure adequacy during electroconvulsive therapy.

The purpose of this study was to assess whether switching propofol to etomidate during an electroconvulsive therapy course improves seizure quality in convulsion-resistant patients. A retrospective study of paired cases included thirty-three patients. Seizure variables for each agent were assessed. A generalized linear mixed model (GLMM) for repeated measures was used for the analysis. Anesthesia with etomidate leads to greater seizure duration, improved seizure quality in the EEG register, and prevents further need for restimulation; although did not differ from propofol in the amount of energy delivered or in other automated parameters. These results suggest that this procedure appears to be an adequate strategy to improve seizure quality.

Developing and Implementing a Quality Assurance Strategy for Electroconvulsive Therapy.

BACKGROUND: The literature provides scant guidance in effective quality assurance strategies concerning the use of electroconvulsive therapy (ECT) for the treatment of psychiatric conditions. Numerous guidelines are published that provide guidance in the delivery of care; however, little has been done to determine how a program or facility might ensure compliance to best practice for safety, tolerability, and efficacy in performing ECT. OBJECTIVE: The objective of this project was to create a quality assurance strategy specific to ECT. Determining standards for quality care and clarifying facility policy were key outcomes in establishing an effective quality assurance strategy. METHODS: An audit tool was developed utilizing quality criteria derived from a systematic review of ECT practice guidelines, peer review, and facility policy. All ECT procedures occurring over a 2-month period of May to June 2017 were retrospectively audited and compared against target compliance rates set for the facility's ECT program. Facility policy was adapted to reflect quality standards, and audit findings were used to inform possible practice change initiatives, were used to create benchmarks for continuous quality monitoring, and were integrated into regular hospital quality meetings. RESULTS: Clarification on standards of care and the use of clinical auditing in ECT was an effective starting point in the development of a quality assurance strategy. Audit findings were successfully integrated into the hospital's overall quality program, and recognition of practice compliance informed areas for future quality development and policy revision in this small community-based hospital in the southeastern United States. CONCLUSIONS: This project sets the foundation for a quality assurance strategy that can be used to help monitor procedural safety and guide future improvement efforts in delivering ECT. Although it is just the first step in creating meaningful quality improvement, setting clear standards and identifying areas of greatest clinical need were crucial beginning for this hospital's growing program.

Pathway to Electroconvulsive Treatment for Minors.

The decision-making process of prescribing electroconvulsive treatment (ECT) to minors often extends outside of medicine. The legal arena is commonly involved in many jurisdictions, and some states have legislation governing the administration of this treatment in addition to hospital policies and regulations. Treatment failures, additional opinions, explicit consent, and legal tribunals are sometimes needed to deliver ECT to a minor in need. This article describes a process to which a provider can refer in navigating this confusing, and sometimes alien, pathway to provide ECT to his or her patient. Individual state statutes pertaining to ECT are provided.
