Electroconvulsive Therapy Credentialing for Psychiatrists-Review of Required Standards Across States and Territories in Australia.

ABSTRACT: Electroconvulsive therapy (ECT) is a complex medical procedure, the delivery of which requires specialist knowledge and skills. We reviewed the standards required for ECT credentialing in different jurisdictions in Australia. We reviewed the Chief Psychiatrist guidelines and statewide policy standards on ECT and focused on standards required for initial credentialing and ongoing privileging in ECT. We compared the credentialing requirements within these documents with the standards specified in the Royal Australian and New Zealand College of Psychiatrists professional practice guideline for ECT. Most of the jurisdictions had specific standards for initial credentialing and maintenance of this credentialing; however, there was significant variance in the credentialing process and standards required. It would be useful to have a minimum standard for credentialing for ECT psychiatrists and prescribers. This standard would be relevant for practice of ECT internationally. States and territories would have the responsibility for implementation of these standards. Appropriate training and establishing good clinical governance processes are essential to the provision of high quality ECT.

Prescribing electroconvulsive therapy for depression: Not as simple as it used to be.

In the last century, prescribing electroconvulsive therapy usually involved considering the relative merits of unilateral versus bilateral electroconvulsive therapy, with most other parameters fixed. However, research over the last 30 years has discovered that several parameters of the electroconvulsive therapy stimulus can have a significant impact on efficacy and cognitive side effects. The stimulus dose relative to seizure threshold was shown to significantly affect efficacy, especially for right unilateral electroconvulsive therapy, where suprathreshold doses in the vicinity of 5-6 times seizure threshold were far more efficacious than doses closer to threshold. However, this did not hold for bitemporal electroconvulsive therapy, where near-threshold stimuli were equally effective as suprathreshold stimuli. Then, changes in stimulus pulse width were found to also have a significant impact on both efficacy and side effects, with ultrabrief pulse widths of 0.3 ms having significantly fewer cognitive side effects in unilateral electroconvulsive therapy than standard brief pulse widths of 1.0 ms, with only slightly reduced efficacy. Therefore, choosing the optimum electroconvulsive therapy prescription for an individual patient now requires consideration of placement, pulse width and stimulus dose relative to seizure threshold, and how these three interact with each other. This viewpoint aims to raise awareness of these issues for psychiatrists involved in electroconvulsive therapy practice.

The place of non-invasive brain stimulation in the RANZCP clinical practice guidelines for mood disorders.

Clinical practice guidelines are important documents as they have the capacity to significantly influence and shape clinical practice in important areas of therapeutics. As such, they need to be developed informed by comprehensive and quality-based systematic reviews, involve consensus deliberations representative of the appropriate experts in the field and be subject to thorough critical review. A revised clinical practice guideline for the management of patients with mood disorders was recently published under the auspices of the Royal Australian and New Zealand College of Psychiatrists. However, this clinical practice guideline was not developed in a manner that reflects the appropriate standards that should apply to clinical practice guideline development and it has critical flaws, especially as it pertains to the use of repetitive transcranial magnetic stimulation treatment for patients with depression. The revision of the college clinical practice guideline has explicitly removed clear and unequivocal evidence-based recommendations that were found in a previous version of the clinical practice guideline and replaced these with consensus-based recommendations. However, the consensus-based recommendations were developed without consultation of the appropriate expert body within the college and contradict the scientific literature. There is substantive and unequivocal evidence supporting the antidepressant use of repetitive transcranial magnetic stimulation in the treatment of patients with depression and its use after a patient with depression has failed a limited number (typically around two) of antidepressant medication trials. Readers should refer to the college Professional Practice Guidelines for repetitive transcranial magnetic stimulation published in 2018 for thorough information about the use of this important new treatment.

Feasibility of the Audio Recorded Cognitive Screen in the Assessment of Individuals Undergoing Electroconvulsive Therapy.

BACKGROUND: Monitoring for cognitive deficits during a course of electroconvulsive therapy (ECT) is recommended, but cognitive assessment can be time consuming. The Audio Recorded Cognitive Screen (ARCS) is a cognitive test instrument with good psychometric properties that places minimal demands on clinicians' time, but until now, it has not been formally evaluated for monitoring cognition in the context of ECT treatment. OBJECTIVES: This study aimed to assess the feasibility/utility of using the ARCS in the assessment of depressed patients undergoing ECT. METHODS: Depressed patients undergoing ECT were tested with the ARCS and a comparison instrument, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), in counterbalance order immediately before any ECT and after the sixth ECT treatment episode. Apathy (Apathy Scale) and depression (Profile of Mood states Short Form) were measured on both occasions. Analyses compared performances on the 2 cognitive instruments and examined for associations with the measures of apathy or depression. RESULTS: Twenty-eight individuals (9 male, 19 female) aged 19 to 84 years underwent testing. Performances on the total ARCS were similar to those on the total RBANS, and both showed decline from baseline to follow-up. The total ARCS and RBANS measures correlated well (r = 0.75, P < 0.001). Neither apathy nor depression scores were significantly associated with scores on either the RBANS or ARCS. CONCLUSIONS: The ARCS was acceptable and convenient in the assessment of cognition in patients undergoing treatment with ECT. In light of its practical advantages, further evaluation of the ARCS for detecting cognitive impairment and tracking cognitive changes during ECT seems warranted.

Royal Australian and New Zealand College of Psychiatrists professional practice guidelines for the administration of electroconvulsive therapy.

OBJECTIVES: To provide guidance for the optimal administration of electroconvulsive therapy, in particular maintaining the high efficacy of electroconvulsive therapy while minimising cognitive side-effects, based on scientific evidence and supplemented by expert clinical consensus. METHODS: Articles and information were sourced from existing guidelines and the published literature. Information was revised and discussed by members of the working group of the Royal Australian and New Zealand College of Psychiatrists' Section for Electroconvulsive Therapy and Neurostimulation, and findings were then formulated into consensus-based recommendations and guidance. The guidelines were subjected to rigorous successive consultation and external review within the Royal Australian and New Zealand College of Psychiatrists, involving the full Section for Electroconvulsive Therapy and Neurostimulation membership, and expert and clinical advisors and professional bodies with an interest in electroconvulsive therapy administration. RESULTS: The Royal Australian and New Zealand College of Psychiatrists' professional practice guidelines for the administration of electroconvulsive therapy provide up-to-date advice regarding the use of electroconvulsive therapy in clinical practice and are informed by evidence and clinical experience. The guidelines are intended for use by psychiatrists and also others with an interest in the administration of electroconvulsive therapy. The guidelines are not intended as a directive about clinical practice or instructions as to what must be done for a given patient, but provide guidance to facilitate best practice to help optimise outcomes for patients. The outcome is guidelines that strive to find the appropriate balance between promoting best evidence-based practice and acknowledging that electroconvulsive therapy is a continually evolving practice. CONCLUSION: The guidelines provide up-to-date advice for psychiatrists to promote optimal standards of electroconvulsive therapy practice.

Effectiveness of left anterior right temporal electrode placement in electroconvulsive therapy: 3 case reports.

Unilateral and bitemporal electrode placement has been the dominant mode of delivery in electroconvulsive therapy. We report 3 patients receiving maintenance electroconvulsive therapy where the use of dominant electrode placements was ineffective. Changing to left anterior right temporal electrode placement resulted in marked clinical improvement. This supports the limited literature on this electrode placement.

Tivantinib for second-line treatment of advanced hepatocellular carcinoma: a randomised, placebo-controlled phase 2 study.

BACKGROUND: Tivantinib (ARQ 197), a selective oral inhibitor of MET, has shown promising antitumour activity in hepatocellular carcinoma as monotherapy and in combination with sorafenib. We aimed to assess efficacy and safety of tivantinib for second-line treatment of advanced hepatocellular carcinoma. METHODS: In this completed, multicentre, randomised, placebo-controlled, double-blind, phase 2 study, we enrolled patients with advanced hepatocellular carcinoma and Child-Pugh A cirrhosis who had progressed on or were unable to tolerate first-line systemic therapy. We randomly allocated patients 2:1 to receive tivantinib (360 mg twice-daily) or placebo until disease progression. The tivantinib dose was amended to 240 mg twice-daily because of high incidence of treatment-emergent grade 3 or worse neutropenia. Randomisation was done centrally by an interactive voice-response system, stratified by Eastern Cooperative Oncology Group performance status and vascular invasion. The primary endpoint was time to progression, according to independent radiological review in the intention-to-treat population. We assessed tumour samples for MET expression with immunohistochemistry (high expression was regarded as ≥2+ in ≥50% of tumour cells). This study is registered with ClinicalTrials.gov, number NCT00988741. FINDINGS: 71 patients were randomly assigned to receive tivantinib (38 at 360 mg twice-daily and 33 at 240 mg twice-daily); 36 patients were randomly assigned to receive placebo. At the time of analysis, 46 (65%) patients in the tivantinib group and 26 (72%) of those in the placebo group had progressive disease. Time to progression was longer for patients treated with tivantinib (1·6 months [95% CI 1·4-2·8]) than placebo (1·4 months [1·4-1·5]; hazard ratio [HR] 0·64, 90% CI 0·43-0·94; p=0·04). For patients with MET-high tumours, median time to progression was longer with tivantinib than for those on placebo (2·7 months [95% CI 1·4-8·5] for 22 MET-high patients on tivantinib vs 1·4 months [1·4-1·6] for 15 MET-high patients on placebo; HR 0·43, 95% CI 0·19-0·97; p=0·03). The most common grade 3 or worse adverse events in the tivantinib group were neutropenia (ten patients [14%] vs none in the placebo group) and anaemia (eight [11%] vs none in the placebo group). Eight patients (21%) in the tivantinib 360 mg group had grade 3 or worse neutropenia compared with two (6%) patients in the 240 mg group. Four deaths related to tivantinib occurred from severe neutropenia. 24 (34%) patients in the tivantinib group and 14 (39%) patients in the placebo group had serious adverse events. INTERPRETATION: Tivantinib could provide an option for second-line treatment of patients with advanced hepatocellular carcinoma and well-compensated liver cirrhosis, particularly for patients with MET-high tumours. Confirmation in a phase 3 trial is needed, with a starting dose of tivantinib 240 mg twice-daily. FUNDING: ArQule, Daiichi Sankyo (Daiichi Sankyo Group).

Multicenter Development and Prospective Validation of eCARTv5: A Gradient Boosted Machine Learning Early Warning Score.

Rationale: Early detection of clinical deterioration using early warning scores may improve outcomes. However, most implemented scores were developed using logistic regression, only underwent retrospective internal validation, and were not tested in important patient subgroups. Objectives: To develop a gradient boosted machine model (eCARTv5) for identifying clinical deterioration and then validate externally, test prospectively, and evaluate across patient subgroups. Methods: All adult patients hospitalized on the wards in seven hospitals from 2008- 2022 were used to develop eCARTv5, with demographics, vital signs, clinician documentation, and laboratory values utilized to predict intensive care unit transfer or death in the next 24 hours. The model was externally validated retrospectively in 21 hospitals from 2009-2023 and prospectively in 10 hospitals from February to May 2023. eCARTv5 was compared to the Modified Early Warning Score (MEWS) and the National Early Warning Score (NEWS) using the area under the receiver operating characteristic curve (AUROC). Measurements and Main Results: The development cohort included 901,491 admissions, the retrospective validation cohort included 1,769,461 admissions, and the prospective validation cohort included 46,330 admissions. In retrospective validation, eCART had the highest AUROC (0.835; 95%CI 0.834, 0.835), followed by NEWS (0.766 (95%CI 0.766, 0.767)), and MEWS (0.704 (95%CI 0.703, 0.704)). eCART's performance remained high (AUROC ≥0.80) across a range of patient demographics, clinical conditions, and during prospective validation. Conclusions: We developed eCARTv5, which accurately identifies early clinical deterioration in hospitalized ward patients. Our model performed better than the NEWS and MEWS retrospectively, prospectively, and across a range of subgroups.

Development and Validation of a Machine Learning COVID-19 Veteran (COVet) Deterioration Risk Score.

BACKGROUND AND OBJECTIVE: To develop the COVid Veteran (COVet) score for clinical deterioration in Veterans hospitalized with COVID-19 and further validate this model in both Veteran and non-Veteran samples. No such score has been derived and validated while incorporating a Veteran sample. DERIVATION COHORT: Adults (age ≥ 18 yr) hospitalized outside the ICU with a diagnosis of COVID-19 for model development to the Veterans Health Administration (VHA) (n = 80 hospitals). VALIDATION COHORT: External validation occurred in a VHA cohort of 34 hospitals, as well as six non-Veteran health systems for further external validation (n = 21 hospitals) between 2020 and 2023. PREDICTION MODEL: eXtreme Gradient Boosting machine learning methods were used, and performance was assessed using the area under the receiver operating characteristic curve and compared with the National Early Warning Score (NEWS). The primary outcome was transfer to the ICU or death within 24 hours of each new variable observation. Model predictor variables included demographics, vital signs, structured flowsheet data, and laboratory values. RESULTS: A total of 96,908 admissions occurred during the study period, of which 59,897 were in the Veteran sample and 37,011 were in the non-Veteran sample. During external validation in the Veteran sample, the model demonstrated excellent discrimination, with an area under the receiver operating characteristic curve of 0.88. This was significantly higher than NEWS (0.79; p < 0.01). In the non-Veteran sample, the model also demonstrated excellent discrimination (0.86 vs. 0.79 for NEWS; p < 0.01). The top three variables of importance were eosinophil percentage, mean oxygen saturation in the prior 24-hour period, and worst mental status in the prior 24-hour period. CONCLUSIONS: We used machine learning methods to develop and validate a highly accurate early warning score in both Veterans and non-Veterans hospitalized with COVID-19. The model could lead to earlier identification and therapy, which may improve outcomes.

Response to endoscopic therapy for biliary anastomotic strictures in deceased versus living donor liver transplantation.

BACKGROUND: Endoscopic therapy has been successful in the management of biliary complications after both deceased donor liver transplantation (DDLT) and living donor liver transplantation (LDLT). LDLT is thought to be associated with higher rates of biliary complications, but there are few studies comparing the success of endoscopic management of anastomotic strictures between the two groups. This study aims to compare our experience in the endoscopic management of anastomotic strictures in DDLT versus LDLT. METHODS: This is a retrospective database review of all liver transplant patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) after liver transplantation. The frequency of anastomotic stricture and the time to develop and to resolve anastomotic stricture were compared between DDLT and LDLT. The response of anastomotic stricture to endoscopic therapy was also analyzed. RESULTS: A total of 362 patients underwent liver transplantation between 2003 and 2011, with 125 requiring ERCP to manage biliary complications. Thirty-three (9.9%) cases of DDLT and 8 (27.6%) of LDLT (P=0.01) were found to have anastomotic stricture. When comparing DDLT and LDLT, there was no difference in the mean time to the development of anastomotic strictures (98+/-17 vs 172+/-65 days, P=0.11), likelihood of response to ERCP [22 (66.7%) vs 6 (75.0%), P=0.69], mean time to the resolution of anastomotic strictures (268+/-77 vs 125+/-37 days, P=0.34), and the number of ERCPs required to achieve resolution (3.9+/-0.4 vs 4.7+/-0.9, P=0.38). CONCLUSIONS: Endoscopic therapy is effective in the majority of biliary complications relating to liver transplantation. Anastomotic strictures occur more frequently in LDLT compared with DDLT, with equivalent endoscopic treatment response and outcomes for both groups.

Patient time costs and out-of-pocket costs in hepatitis C.

BACKGROUND: Hepatitis C virus (HCV) infection is associated with substantial costs to patients, their caregivers and society. AIMS: We evaluated time costs (time spent seeking healthcare) and out-of-pocket (OOP) costs for patients with HCV and their caregivers. METHODS: We measured costs for 738 HCV outpatients in a tertiary-care clinic using a patient-completed questionnaire. Time and OOP costs were compared across disease stages and sociodemographic categories. We examined the association between cost and disease stage using linear regression adjusting for age, gender, marital status, education, income and Index of Coexistent Disease (ICED) comorbidity score. Costs were expressed in 2007 Canadian dollars. RESULTS: The mean annual time cost per patient was $2136 (98 h), and ranged from $281 (18 h) in individuals who had cleared the virus to $9416 in transplant recipients (420 h). Caregiver costs were reported in 10% of patients. The mean annual OOP cost per patient was $1326. Patients receiving active treatment and those with late-stage disease spent $2500-2800 per year on HCV-related healthcare, approximately 7% of their annual income. Patients who had cleared the virus had the lowest time and OOP costs. Low income and unemployed patients had higher costs. CONCLUSIONS: In HCV-infected individuals, OOP and time costs represent a significant economic burden and fall disproportionately upon those least able to afford them. The lower cost burden among those who were successfully treated suggests that wider use of antiviral therapy may reduce economic burden in addition to improving health outcomes.

Health utilities and psychometric quality of life in patients with early- and late-stage hepatitis C virus infection.

BACKGROUND AND AIM: Hepatitis C virus (HCV) infection is associated with impairment in health-related quality of life (HRQOL). The purpose of this study was to evaluate HRQOL across the HCV disease spectrum using preference-based (utility) and non-preference-based (psychometric) methods, adjusting for sociodemographic factors and co-morbidity. METHODS: Hepatitis C virus patients (n = 751) were recruited from several tertiary care settings in Vancouver, Canada for this observational, cross-sectional cohort study. Patients completed the Health Utilities Index Mark 2/3, a self-administered time trade-off utility instrument, and the Hepatitis Quality of Life Questionnaire (SF-36 with HCV-specific items). We examined the association between HRQOL and disease stage using linear regression adjusting for age, education, marital status, income, and co-morbidities. RESULTS: Utility scores were low across disease stage and instrument, ranging from 0.51 to 0.80. On the SF-36, the mean Physical Component Summary score ranged from 37.2 to 49.2 across disease stage, and the Mental Component Summary score ranged from 39.7 to 45.7 (United States norms = 50). In general, patients with viral clearance had the highest scores, and those with late-stage disease (cirrhosis, liver cancer) had the lowest. Multivariable linear regression showed that the effect of disease stage was modest overall. Increasing age, lower income, unattached marital status, and high comorbidity were strongly associated with impairment in HRQOL. CONCLUSIONS: The effect of stage of disease on HRQOL is modest, although viral clearance is associated with higher HRQOL. HCV patients' HRQOL is strongly associated with concomitant illness and sociodemographic factors.

Electroconvulsive therapy training: can it be a model of an entrustable professional activity in a competency program?

OBJECTIVES: This paper gives an overview of the teaching and assessment process in electroconvulsive therapy (ECT) provided in the Hunter Region to see if it can be used as a successful example of competency assessment and training. We describe the process and practice of training and credentialing in ECT in the Hunter Region, and compare these with the requirements of an Entrustable Professional Activity (EPA) in particular and competency based training and assessment in general. CONCLUSION: The intensely supervised 'hands on' training and assessment in this program, and the entrusting of successful graduates to perform ECT and related activities with sufficient independence, demonstrate an 'Entrustable Professional Activity' as proposed for introduction in the Royal Australian and New Zealand College of Psychiatrists Competency Based Fellowship Program.

Relapse of multiple myeloma presenting with biliary obstruction.

Pancreatic infiltration is a rare feature of multiple myeloma. A case of a 74-year-old man presenting with symptomatic biliary obstruction two years after the original diagnosis of myeloma is described. Confirmation of pancreatic infiltration with myeloma cells was performed by endoscopic ultrasound-guided fine-needle aspiration. Biliary stenting was performed at endoscopic retrograde cholangiopancreatography. Resolution of the pancreatic mass and the associated biliary stricture was observed after radiation and chemotherapy.

Multimodal therapy for hepatocellular carcinoma: a complementary approach to liver transplantation.

OBJECTIVE: To evaluate the survival benefit of multimodal therapy for the treatment of HCC. BACKGROUND: Orthotopic liver transplantation (OLT) is considered the treatment of choice for selected patients with hepatocellular carcinoma (HCC). However, donor organ shortages and patients whose HCCs exceed OLT criteria require consideration of alternate therapeutic options such as hepatic resection, radiofrequency ablation (RFA), ethanol injection (EI), transarterial chemoembolization (TACE), and chemotherapy (CTX). This study was performed to evaluate the survival benefit of multimodal therapy for treatment of HCC as complementary therapy to OLT. METHODS: A retrospective review was conducted of HCC patients undergoing therapy following multidisciplinary review at our institution from 1996 . 2006 with a minimum of a 2 year patient follow-up. Data were available on 247/252 patients evaluated. Relevant factors at time of diagnosis included symptoms, hepatitis B (HBV) and C (HCV) status, antiviral therapy, Child-Pugh classification, portal vein patency, and TNM staging. Patients underwent primary treatment by hepatic resection, RFA, EI, TACE, CTX, or were observed (best medical management). Patients with persistent or recurrent disease following initial therapy were assessed for salvage therapy. Survival curves and pairwise multiple comparisons were calculated using standard statistical methods. RESULTS: Mean overall survival was 76.8 months. Pairwise comparisons revealed significant mean survival benefits with hepatic resection (93.2 months), RFA (66.2 months), and EI (81.1 months), compared with TACE (47.4 months), CTX (24.9 months), or observation (31.4 months). Shorter survival was associated with symptoms, portal vein thrombus, or Child-Pugh class B or C. HCV infection was associated with significantly shorter survival compared with HBV infection. Antiviral therapy was associated with significantly improved survival in chronic HBV and HCV patients only with earlier stage disease. CONCLUSION: Multimodal therapy is effective therapy for HCC and may be used as complementary treatment to OLT.
