Play, Learn, and Teach Outdoors-Network (PLaTO-Net): terminology, taxonomy, and ontology.

BACKGROUND: A recent dialogue in the field of play, learn, and teach outdoors (referred to as "PLaTO" hereafter) demonstrated the need for developing harmonized and consensus-based terminology, taxonomy, and ontology for PLaTO. This is important as the field evolves and diversifies in its approaches, contents, and contexts over time and in different countries, cultures, and settings. Within this paper, we report the systematic and iterative processes undertaken to achieve this objective, which has built on the creation of the global PLaTO-Network (PLaTO-Net). METHODS: This project comprised of four major methodological phases. First, a systematic scoping review was conducted to identify common terms and definitions used pertaining to PLaTO. Second, based on the results of the scoping review, a draft set of key terms, taxonomy, and ontology were developed, and shared with PLaTO members, who provided feedback via four rounds of consultation. Third, PLaTO terminology, taxonomy, and ontology were then finalized based on the feedback received from 50 international PLaTO member participants who responded to ≥ 3 rounds of the consultation survey and dialogue. Finally, efforts to share and disseminate project outcomes were made through different online platforms. RESULTS: This paper presents the final definitions and taxonomy of 31 PLaTO terms along with the PLaTO-Net ontology model. The model incorporates other relevant concepts in recognition that all the aspects of the model are interrelated and interconnected. The final terminology, taxonomy, and ontology are intended to be applicable to, and relevant for, all people encompassing various identities (e.g., age, gender, culture, ethnicity, ability). CONCLUSIONS: This project contributes to advancing PLaTO-based research and facilitating intersectoral and interdisciplinary collaboration, with the long-term goal of fostering and strengthening PLaTO's synergistic linkages with healthy living, environmental stewardship, climate action, and planetary health agendas. Notably, PLaTO terminology, taxonomy and ontology will continue to evolve, and PLaTO-Net is committed to advancing and periodically updating harmonized knowledge and understanding in the vast and interrelated areas of PLaTO.

The Impact of COVID-19 on Electroconvulsive Therapy: A Multisite, Retrospective Study From the Clinical Alliance and Research in Electroconvulsive Therapy and Related Treatments Network.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has led to reported change in electroconvulsive therapy (ECT) services worldwide. However, minimal data have been published demonstrating tangible changes across multiple ECT centers. This article aimed to examine changes in ECT patients and ECT service delivery during the pandemic. METHODS: We retrospectively assessed data collected on ECT patients within the Clinical Alliance and Research in Electroconvulsive Therapy and Related Treatments (CARE) Network during a 3-month period starting at the first COVID-19 restrictions in 2020 and compared data with predicted values based on the corresponding 3-month period in 2019. Mixed-effects repeated-measures analyses examined differences in the predicted and actual number of acute ECT courses started and the total number of acute ECT treatments given in 2020. Sociodemographic, clinical, treatment factors, and ECT service delivery factors were compared for 2020 and 2019. RESULTS: Four Australian and 1 Singaporean site participated in the study. There were no significant differences between the predicted and actual number of acute ECT courses and total number of acute ECT treatments administered in 2020. During 2020, there were statistically significant increases in the proportion of patients requiring ECT under substitute consent and receiving ECT for urgent reasons compared with 2019. CONCLUSIONS: This multisite empirical study is among the first that supports anecdotal reports of changes in the triaging and delivery of ECT during COVID-19. Results suggest that ECT was prioritized for the most severely ill patients. Further data assessing the impacts of COVID-19 on ECT are needed.

Use of ultrabrief pulse width electroconvulsive therapy to induce therapeutic seizures in an elderly patient with a high seizure threshold: a case report.

OBJECTIVE: This case report describes a 73-year-old man suffering from unipolar major depression with melancholic features, in whom treatment with electroconvulsive therapy (ECT) proved difficult due to inadequate seizure generation. METHODS: A number of augmentation strategies were trialled in an attempt to improve seizure quality. Pre-ECT and Post-ECT measurement of symptoms, quality of life and cognition were undertaken with a variety of validated scales. RESULTS: The single most efficacious strategy to elicit therapeutic seizures was the use of right unilateral (RUL) electrode placement with an ultrabrief pulse width. The patient subsequently had a resolution of his depressive illness, with a concomitant improvement in cognitive functioning. CONCLUSION: This case demonstrates that a number of ECT augmentation strategies can be used in routine clinical practice for patients with high seizure thresholds. It highlights that UB pulse width may be considered earlier in the treatment course for patients in whom conventional brief pulse ECT fails to generate effective seizures.

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.

The Clinical Alliance and Research in Electroconvulsive Therapy Network: An Australian Initiative for Improving Service Delivery of Electroconvulsive Therapy.

OBJECTIVE: There is currently substantial heterogeneity in electroconvulsive therapy (ECT) treatment methods between clinical settings. Understanding how this variation in clinical practice is related to treatment outcomes is essential for optimizing service delivery. The Clinical Alliance and Research in ECT Network is a clinical and research framework with the aims of improving clinical practice, enabling auditing and benchmarking, and facilitating the collection of naturalistic clinical data. METHODS: The network framework and clinical and treatment variables collected and rationale for the use of particular outcome measures are described. Survey results detailing the use of ECT across initial participating clinical centers were examined. RESULTS: The data are reported from 18 of 22 participating centers, the majority based in Australia. Melancholic unipolar depression was the most common clinical indication (78%). Right unilateral (44%) and bifrontal (39%) were the most commonly used electrode placements. Eighty one percent of the centers used individual seizure titration for initial dosing. CONCLUSIONS: There was substantial heterogeneity in the use of ECT between participating centers, indicating that the Network is representative of modern ECT practice. The Clinical Alliance and Research in ECT Network may therefore offer the opportunity to improve service delivery and facilitate the investigation of unresolved research questions pertaining to modern ECT practice.

Seizure threshold increases can be predicted by EEG quality in right unilateral ultrabrief ECT.

Increases in seizure threshold (ST) over a course of brief pulse ECT can be predicted by decreases in EEG quality, informing ECT dose adjustment to maintain adequate supra-threshold dosing. ST increases also occur over a course of right unilateral ultrabrief (RUL UB) ECT, but no data exist on the relationship between ST increases and EEG indices. This study (n = 35) investigated if increases in ST over RUL UB ECT treatments could be predicted by a decline in seizure quality. ST titration was performed at ECT session one and seven, with treatment dosing maintained stable (at 6-8 times ST) in intervening sessions. Seizure quality indices (slow-wave onset, mid-ictal amplitude, regularity, stereotypy, and post-ictal suppression) were manually rated at the first supra-threshold treatment, and last supra-threshold treatment before re-titration, using a structured rating scale, by a single trained rater blinded to the ECT session being rated. Twenty-one subjects (60%) had a ST increase. The association between ST changes and EEG quality indices was analysed by logistic regression, yielding a significant model (p < 0.001). Initial ST (p < 0.05) and percentage change in mid-ictal amplitude (p < 0.05) were significant predictors of change in ST. Percentage change in post-ictal suppression reached trend level significance (p = 0.065). Increases in ST over a RUL UB ECT course may be predicted by decreases in seizure quality, specifically decline in mid-ictal amplitude and potentially in post-ictal suppression. Such EEG indices may be able to inform when dose adjustments are necessary to maintain adequate supra-threshold dosing in RUL UB ECT.

Health Related Quality of Life after ECT for depression: A study exploring the role of different electrode-placements and pulse-widths.

INTRODUCTION: Prior research has shown large improvements in HRQOL after a course of ECT for depression. However, the effect of different types of ECT on HRQOL outcomes has not been explored. This is important due to the considerable range of ECT treatment modalities that currently exist in clinical practice. METHODS: HRQOL data from 355 depressed patients in three Australian clinical hospitals, who received ECT given with a range of treatment modalities (combinations of pulse-width and electrode-placement), were analysed. HRQOL was measured at baseline and after ECT, using the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF). The association between type of ECT and HRQOL after ECT was examined by regression analysis, controlling for variables that may affect HRQOL outcomes. RESULTS: There was a significant increase in HRQOL scores after ECT (p<0.0001; t=-23.4). The magnitude of change was large (54% increase, Cohen's d=1.43). Multiple regression analysis yielded a significant model (P<0.001, R2=0.18). Baseline HRQOL score (t=4.83; p<0.0001), age (t=2.75, p<0.01) and type of ECT received [Right Unilateral brief vs Bitemporal Ultrabrief (t=-2.99; p<0.01) and Right Unilateral brief vs Bifrontal Ultrabrief (t=-2.70; p<0.01)] were significant predictors of HRQOL after the ECT course. LIMITATIONS: Data was collected naturalistically from clinical services, thus ECT modality was not randomly assigned. Site could have confounded results. CONCLUSIONS: An acute course of ECT for depression produced statistically and clinically significant improvements in HRQOL. ECT treatment modality can substantially impact HRQOL outcomes, with the possibility of bilateral ultrabrief forms of ECT being less beneficial.

Need to titrate in ultrabrief electroconvulsive therapy--need for more evidence.

A recent audit on ultrabrief electroconvulsive therapy (ECT) at our hospital revealed that most of the patients had an increase in seizure threshold during their routine dose retitration at session 7. These patients subsequently received an increased dose to sustain a therapeutic dose of 6 times the seizure threshold. Our results raise the possibility that patients may be receiving inadequate doses before retitration in the setting of rising seizure thresholds, thus potentially affecting the efficacy of ultrabrief ECT. Further studies are needed to provide more insight into the need for retitration and in determining the optimal therapeutic dose in ultrabrief ECT.

Malingered psychosis leading to involuntary psychiatric hospitalization.

OBJECTIVE: To describe a patient with feigned psychosis who was admitted to an acute psychiatric unit under the Mental Health Act, and to discuss the clinical features of malingering in this treatment setting. METHOD: Case report. RESULTS: A 40-year-old man with no known past psychiatric history was brought by police to the Emergency Department. He gave a history of paranoia, hallucinations and bizarre behaviour and was admitted to a secure ward. Treatment with parenteral medication was required due to hostile and aggressive behaviour. Collateral history was inconsistent with his reported symptoms and, when confronted with this information, he acknowledged fabricating his symptoms in order to obtain a disability pension. CONCLUSIONS: It is important to consider malingering as a differential diagnosis in patients who present with atypical features and have clear external incentives for their behaviour. With improved health literacy and access to health information, individuals who are marginalized in society and have limited social and occupational opportunities may malinger symptoms for obvious personal gain. Inconsistency between reported symptoms and clinical observations, as well as contradictory collateral information from multiple sources, are helpful tools in diagnosing malingering. It is important for clinicians to identify malingerers early and limit unnecessary admissions.
