Relapse after abrupt discontinuation of maintenance electroconvulsive therapy during the COVID-19 pandemic

Vagus nerve stimulation allows to cease maintenance electroconvulsive therapy in treatment-resistant depression: a retrospective monocentric case series

Context

The use of vagus nerve stimulation (VNS) to reduce or stop electroconvulsive therapy (ECT) in treatment-resistant depression seems promising. The aim of this study was to investigate the efficacy of VNS on the reduction of ECT sessions and mood stabilization.

Methods

We conducted a monocentric retrospective case series of patients who suffered from treatment-resistant depression, treated with ECT and referred to our center for VNS. We investigated the number and the frequency of ECT sessions before and after VNS implantation. Secondary criteria consisted in the Montgomery Åsberg Depression Rating Scale (MADRS) score, number of medical treatments, dosage of the main treatment and length of hospital stays before and after VNS. Additionally, we sent an anonymous survey to psychiatrists and other physicians in our institution to investigate their knowledge and perception of VNS therapy to treat treatment-resistant depression.

Results

Seven patients benefited from VNS: six (86%) were female (mean age of 51.7 +/- 16.0 years at surgery), and five (71%) suffered from bipolar depression (three type I and two type II). All patients were followed up at least 2 years post-implantation (range: 27-68 months). Prior to VNS, six patients were treated by maintenance ECT. After VNS, three (43%) patients did not require maintenance ECT anymore, and three (43%) patients required less frequent ECT session with a mean 14.7 +/- 9.8 weeks between sessions after VNS vs. 2.9 +/- 0.8 weeks before VNS. At last follow-up, 4 (57%) patients had stopped ECT. Five (71%) patients implanted with VNS were good responders (50% decrease relative to baseline MADRS). According to the survey, psychiatrists had a significantly better perception and knowledge of ECT, but a worse perception and knowledge of VNS compared to other physicians.

Conclusion

VNS is a good option for treatment-resistant depression requiring maintenance ECT dependence. Larger on-going studies will help broaden the implanted patients while strengthening psychiatrists' knowledge on this therapy.

Long-Term Effect of Maintenance Electroconvulsive Therapy in Patients With Depression-Data From a Small Randomized Controlled Trial

OBJECTIVES

This study aimed to compare the long-term effects of maintenance electroconvulsive therapy (M-ECT) with medication and medication only in patients with depression.

METHODS

A randomized controlled trial of 1 year of M-ECT with medication or medication only investigated relapse/recurrence among 56 patients in remission after electroconvulsive therapy (ECT) for depression was conducted. The results of the first year are published already and showed a significant advantage of M-ECT with medication.The current study was a long-term follow-up. When the randomized treatment allocation ended, medication was continued in both groups but M-ECT was terminated. Patients were followed for up to 10 years via Swedish national registers until the study endpoint of a new psychiatric diagnosis as an inpatient, suicide, suspected suicide, or death of another cause. Time to relapse was compared between the M-ECT with medication group and the medication-only group using Kaplan-Meier estimates.

RESULTS

The median follow-up time was 6.5 years for the M-ECT and medication group and 3.1 years for the medication-only group. One year after randomization 22 patients remained in the M-ECT and medication group, and 14 patients remained in the medication-only group. Relapse patterns between the treatment groups after the completion of M-ECT seemed to be similar according to visual inspection.

CONCLUSIONS

This long-term follow-up study suggests that most of the benefit achieved during the treatment period with M-ECT is maintained over several years, but the small sample size, with accompanying large statistical imprecision, makes the results uncertain. More long-term studies of M-ECT are required.Trial registration: ClinicalTrials.gov identifier: NCT00627887.

Etomidate versus propofol for electroconvulsive therapy: An intraindividual comparative study during the COVID-19 pandemic

OBJECTIVES

The Coronavirus disease 2019 (COVID-19) pandemic markedly influenced mental health care practices, notably regarding electroconvulsive therapy (ECT). This was due to the redistribution of anesthetic agents used during ECT such as propofol, for intensive care units. Because in our center propofol was switched to etomidate to avoid ECT activity discontinuation, we undertook this study in order to compare Propofol and Etomidate regarding electroencephalographic seizure duration and stimulus intensity.

METHODS

We performed a retrospective and comparative study, each patient being its own control. We included patients with at least two courses of ECT on propofol and two others with etomidate over the period from September 2019 to April 2021, regardless of the psychiatric diagnosis. Our data collection process notably targeted stimulus intensity, seizure duration recorded using electroencephalography, and medication used for anesthetic induction.

RESULTS

Overall, we included 18 patients with a male: female ratio of 1:2.6 and a mean (and standard deviation) age of 62.7±13.4 years. We found that the mean intensity of stimulation was significantly lower with etomidate when compared to propofol (425.3±250.0 vs. 658.9±280.2 mC, P=0.001). The mean duration of electroencephalographic seizure was significantly higher with etomidate in comparison to propofol (53.5±16.6 vs. 35.0±12.2seconds, P<0.001).

CONCLUSION

By using each patient as its own control, our study found that etomidate, while compared to propofol, was related to a lower level of stimulatory intensity and a longer electroencephalographic seizure duration.

Impact on Electroconvulsive Therapy Services, Including Patient Relapse and Death, During the COVID-19 Pandemic: Quantitative Results From a Multinational Survey

OBJECTIVES

Electroconvulsive therapy (ECT) is important in the management of major, life-threatening, and treatment-resistant psychiatric illness. The COVID-19 pandemic has significantly disrupted ECT services. The need for new infection control measures, staff redeployment and shortages, and the perception that ECT is as an "elective" procedure have caused changes to, and reductions in, ECT delivery. The aim of this study was to explore the impact of COVID-19 on ECT services, staff, and patients globally.

METHODS

Data were collected using an electronic, mixed-methods, cross-sectional survey. The survey was open from March to November 2021. Clinical directors in ECT services, their delegates, and anesthetists were asked to participate. Quantitative findings are reported.

RESULTS

One hundred and twelve participants worldwide completed the survey. The study identified significant impacts on services, staff, and patients. Importantly, most participants (57.8%; n = 63) reported their services made at least 1 change to ECT delivery. More than three-quarters (81.0%; n = 73) reported that their service had identified at least 1 patient who could not access ECT. More than two-thirds (71.4%; n = 67) reported that their service identified patients who experienced a relapse in their psychiatric illness due to lack of ECT access. Six participants (7.6%) reported that their service had identified at least 1 patient who died, by suicide or other means, due to lack of ECT access.

CONCLUSIONS

All ECT practices surveyed were impacted by COVID-19 with decreases in capacity, staffing, changes in workflow, and personal protective equipment requirements with relatively little change to ECT technique. Lack of access to ECT resulted in significant morbidity and mortality, including suicide, internationally. This is the first multisite, international survey to explore the impacts of COVID-19 on ECT services, staff, and patients.

Changes in Inpatient Electroconvulsive Therapy Utilization Between 2019 and 2020: A National Inpatient Sample Analysis

OBJECTIVES

Electroconvulsive therapy (ECT) is an essential procedure for a range of psychiatric conditions. Multiple single-center studies have documented reduction in ECT administration in 2020 because of the coronavirus disease 2019 pandemic, but there have been little nationally representative data from the United States. The aim of this study was to examine the demographics of patients receiving ECT in 2019 and 2020 and to characterize temporal and regional variations in ECT utilization.

METHODS

The 2019 and 2020 National Inpatient Sample, an administrative database of inpatient hospitalizations in the United States, was queried for hospitalizations involving the delivery of ECT based on procedural codes. Overall number of ECT procedures was calculated based on the overall number of ECT procedural claims.

RESULTS

In the 2019 NIS, 14,230 inpatient hospitalizations (95% confidence interval, 12,936-15,524) involved the use of ECT, with a cumulative 52,450 inpatient ECT procedures administered. In 2020, the number of inpatient hospitalizations with ECT decreased to 12,055 (95% confidence interval, 10,878-13,232), with a 10.0% reduction in overall procedures to 47,180. Whereas January and February ECT hospitalizations were comparable in both years, ECT hospitalizations decreased by more than 25% in March through May 2020 relative to 2019 volume. There was regional variability in the change in ECT utilization between 2019 and 2020.

CONCLUSIONS

Electroconvulsive therapy use among general hospital inpatients declined between 2019 and 2020, with regional variability in the magnitude of change. Further study is warranted into the root causes and optimal responses to these changes.

Psychiatric Boarding in Emergency Departments and the COVID-19 First Wave: The New Hampshire Response

The COVID-19 pandemic forced unprecedented challenges for emergency department operations during the spring of 2020. Before the COVID-19 pandemic, psychiatric boarding in emergency departments required a substantial amount of staffing and administrative resources. This case study describes one state's efforts to rapidly decrease psychiatric boarding by 93% in 2 weeks with a multipronged approach, and simultaneously minimal effects observed on outcome measures of psychiatric hospital readmissions and suicide rates. Lessons learned are discussed regarding workflow adaptations and leadership implications.

Strategies from A Multi-National Sample of Electroconvulsive Therapy (ECT) Services: Managing Anesthesia for ECT during the COVID-19 Pandemic

Electroconvulsive therapy (ECT) is important in the management of severe, treatment-resistant, and life-threatening psychiatric illness. Anesthesia supports the clinical efficacy and tolerability of ECT. The COVID-19 pandemic has significantly disrupted ECT services, including anesthesia. This study documents strategies for managing ECT anesthesia during the pandemic. Data were collected between March and November 2021, using a mixed-methods, cross-sectional, electronic survey. Clinical directors in ECT services, their delegates, and anesthetists worldwide participated. One hundred and twelve participants provided quantitative responses to the survey. Of these, 23.4% were anesthetists, and the remainder were ECT clinical directors. Most participants were from Australia, New Zealand, North America, and Europe. Most were located in a public hospital, in a metropolitan region, and in a ‘medium/high-risk’ COVID-19 hotspot. Half of the participants reported their services made changes to ECT anesthetic technique during the pandemic. Services introduced strategies associated with anesthetic induction, ventilation, use of laryngeal mask airways, staffing, medications, plastic barriers to separate staff from patients, and the location of extubation and recovery. This is the first multi-national, mixed-methods study to investigate ECT anesthesia practices during the COVID-19 pandemic. The results are vital to inform practice during the next waves of COVID-19 infection, ensuring patients continue to receive ECT.

Provision of Electroconvulsive Therapy During the COVID-19 Pandemic: A Survey Among Clinics in Germany, Austria, and Switzerland

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic has had a marked impact on psychiatry. Capacity reductions also affected electroconvulsive therapy (ECT), even though ECT is an essential rather than an elective procedure. We sent a survey to all 197 clinics in Germany, Austria, and Switzerland with an ECT service between March and May 2021 to provide an overview of the changes made to ECT services in these countries during the acute phase of the COVID-19 pandemic. More than a quarter of the clinics (27.0%) reported a temporary suspension of all ECT treatments, and 28.2% of the clinics reported reductions of up to 75%. Maintenance ECT was suspended in 46.7% of the clinics and reduced by up to 75% in 30.6% of the clinics. At the time of the survey, 40.8% of the clinics still reported lower numbers of ECT treatments compared with the prepandemic situation. Reasons for the reduced number of ECT treatments included patient safety and testing measures, personnel shortages in the anesthesiology departments, and limited availability of rooms. The COVID-19 pandemic had and continues to have a marked negative impact on the provision of ECT in clinics in Germany, Austria, and Switzerland. To avoid negative consequences for patients, ECT clinics should urgently take steps to provide ECT services without disruptions.

Psychotic disorders amid the COVID-19 pandemic: a consideration of risks and impacts

PURPOSE OF REVIEW

The COVID-19 pandemic has had a severe and widespread global impact but particularly for those with psychosis. This review summarizes recent evidence on the relationship between the COVID-19 pandemic and psychotic disorders, highlighting the risks faced by these individuals including the negative impacts on treatment services, complications from contracting COVID-19, and the acceptability of digital interventions.

RECENT FINDINGS

Mortality, morbidity, and infection outcomes are among the worst for individuals with psychotic disorders. Presentation rates for psychotic disorders are elevated at emergency departments compared with before the COVID-19 pandemic; demand for inpatient services has increased, and there have been complications in access because of pandemic restrictions. COVID-19 related stressors have led to the exacerbation and incidence of psychotic symptoms among individuals with and without preexisting psychotic diagnoses. Digital interventions may be an acceptable method for maintaining patient contact and treatment during extended isolation.

SUMMARY

More data is needed on the longitudinal trajectory for psychotic symptoms post-COVID-19 infection and pandemic restrictions to better support individuals with psychotic disorders. Development of a long-term pandemic management plan is needed to monitor and support psychiatric health across the population.

A comparison of the safety, feasibility, and tolerability of ECT and ketamine for treatment-resistant depression

INTRODUCTION

Treatment-resistant depression (TRD) is a problematic and prevalent public health and societal concern. Although electroconvulsive therapy (ECT) is the gold standard TRD intervention, the treatment evokes apprehension due to public perceptions, feasibility, and tolerability. Despite significant medical advancements, few medications have been approved by the U.S. Food and Drug Administration for TRD. In 2019, intranasal esketamine, the S-isomer of racemic ketamine, was approved for TRD, garnering significant excitement about the potential for the drug to act as an alternative treatment to ECT.

AREAS COVERED

The goal of this narrative review is to compare the safety, efficacy, and tolerability of ketamine and ECT; clarify whether ketamine is a reasonable alternative to ECT; and to facilitate improved treatment assignment for TRD. Empirical quantitative and qualitative studies and national and international guidelines these treatments are reviewed.

EXPERT OPINION

: The field awaits the results of two ongoing large comparative effectiveness trials of ECT and IV ketamine for TRD, which should help guide clinicians and patients as to the relative risk and benefit of these interventions. Over the next five years we anticipate further innovations in neuromodulation and in drug development which broadly aim to develop more tolerable versions of ECT and ketamine, respectively.

An Online Survey About Electroconvulsive Therapy in Japan During the COVID-19 Pandemic: Comparison of Early and Recent Stages

PURPOSE

To provide an overview of how electroconvulsive therapy (ECT) practice in Japan has changed as the coronavirus disease 2019 (COVID-19) pandemic continues.

PATIENTS AND METHODS

We surveyed healthcare institutions, primarily university and general hospitals, regarding changes in the number of patients undergoing ECT and infection control measures in the early (August 2020) and recent (August 2021) stages of the COVID-19 pandemic. Data for the early and recent stages were also compared between urban and non-urban areas.

RESULTS

Among 32 facilities, the number of patients undergoing ECT decreased in 11 facilities (34.4%) from April 2020 to March 2021 compared with the previous year, whereas the number increased in 12 (37.5%) from April to June 2021 compared with the previous year. As of August 2021, some facilities had ongoing restrictions. Compared with non-urban facilities, the number of patients undergoing ECT decreased more in urban facilities, which also had more ECT restrictions. Maintenance ECT was used at the same rate as before the pandemic for 23 (82.1%) of 28 institutions. Regarding infection control measures, many facilities considered polymerase chain reaction testing before ECT and required all staff to wear surgical masks and eye shields during ECT.

CONCLUSION

The COVID-19 pandemic in Japan greatly affected the use of ECT in 2020; however, by the summer of 2021, infection control measures were relatively well established, the number of ECT cases stabilized and increased, and the decision to use ECT was again possible.
