Acta Psychiatr Scand 2022; 147:403-419. [PMID: 35996219 DOI: 10.1111/acps.13492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 07/30/2022] [Accepted: 08/13/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND Delirium is costly for patients, carers, and healthcare systems. In addition, non-pharmacological and pharmacological management of delirium is challenging. Electroconvulsive therapy (ECT) has been proposed and used as an anecdotal treatment of delirium in clinical practice. However, the efficacy and safety of this approach are not well understood. OBJECTIVE To synthesise and review the evidence relating to the safety and efficacy of ECT as a treatment for delirium. METHODS A systematic review was completed according to PRISMA guidelines using the PubMed, CINAHL, Cochrane Library, and PsycINFO databases. Studies were eligible for inclusion if modified ECT was used to treat delirium symptoms. ECT for delirium in people with neuroleptic malignant syndrome, catatonia, or confusional states associated with acute primary psychiatric conditions were excluded. All included records were first ranked using the hierarchy of evidence-based medicine; quality was then assessed using the Joanna Briggs critical appraisal checklists. Pooled data across the cases identified were analysed using descriptive statistics. RESULTS Of 1226 records screened, 10 studies met inclusion criteria: six case reports, three case series, and one quasi-experimental study. The literature base was of mixed quality. A single quasi-experimental study was assessed to be of 'fair' quality, the remainder of the case series and case reports were rated as 'poor' to 'fair' quality. A total of only 40 individual people with delirium who were treated with ECT were identified. In 33/40 cases, the aetiology of delirium was substance withdrawal. The number of ECT treatments administered ranged from 1 to 13. ECT was reported to positively contribute towards treatment of delirium in all cases, although objective measures of improvement were reported in only 6/13 patient cases from case reports and case series (46%). The singular quasi-experimental study reported a statistically significant decrease in duration of delirium, time spent in physical restraint, and in benzodiazepine requirement when ECT was used as an adjunct in benzodiazepine withdrawal delirium. When adverse events were described these included mild confusion and memory deficits; all were reported as time limited and reversible. Considerable limitations in the quality of the evidence base were identified, including the risk of selection, publication and reporting bias. Much data reporting on safety and efficacy of ECT in delirium was missing. CONCLUSION There is insufficient literature to support modified ECT as a clinical treatment for delirium. The few studies identified were generally of weak evidence lacking important data on safety and objective outcome measures, and not including populations with broad delirium aetiologies. Further research using more robust methodologies and broader populations (age, aetiology) of people with delirium treated with ECT is needed.

Knowledge, attitude, and practice toward delirium and subtype assessment among Chinese clinical nurses and determinant factors: A multicentre cross-section study. Front Psychiatry 2022; 13:1017283. [PMID: 36819944 PMCID: PMC9929153 DOI: 10.3389/fpsyt.2022.1017283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Accepted: 12/23/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Delirium, a confused transient state of consciousness, can be divided into hyperactive, hypoactive, mixed, and no motor subtypes, according to different clinical manifestations. Several studies have investigated delirium subtypes in the knowledge dimension, but few studies have investigated delirium subtype in the attitude and practice dimensions. The barriers, knowledge sources, and practice details regarding subtype assessment are unclear. OBJECTIVES This study had three objectives. First, we planned to investigate the KAP status regarding delirium and subtypes for nurses. Second, we wanted to identify factors affecting clinical nurses' KAP scores. Third, this study expected to explore more details regarding delirium and subtypes assessment, including assessment barriers, assessment instruments, and knowledge sources. METHODS This multicentre cross-section study was conducted in 10 tertiary hospitals in three provinces, China, from January to April 2022. We investigated 477 nurses from six departments with a high prevalence. The self-developed KAP questionnaire regarding delirium and subtypes assessment had four parts: knowledge, attitude, practice, and source. Its reliability and validity were verified effectively by 2-round Delphi expert consultation. RESULTS A total of 477 nurses from the general intensive care unit (ICU), specialty ICU, orthopedics, thoracic surgery, operating room, and geriatrics were 28.3, 22.4, 22.2, 10.5, and 5.2%, respectively. The total KAP score regarding delirium and subtypes assessment was 60.01 ± 6.98, and the scoring rate was 73.18%. The scoring rate for knowledge, attitude, and practice was 58.55, 83.94, and 51.70%, respectively. More than half (54.1%) were unaware of the delirium subtypes assessment instruments. A total of 451 (94.6%) participants recognized the importance of nursing work for delirium prevention. A total of 250 (52.4%) nurses occasionally or sometimes assessed delirium subtypes, and 143 (30.0%) never assessed for delirium subtypes. We found that age, department, technical title, familiarity with delirium, familiarity with delirium subtypes, delirium training, and subtype training affected the total KAP scores. ICU nurses achieved the highest scores. CONCLUSION Chinese nurses' KAP status regarding delirium and subtypes assessment were barely acceptable, and the attitude score was positive, but knowledge and practice needed improvement. Meanwhile, the department was one of the significant KAP factors, and ICU nurses did better in delirium and subtype assessment in knowledge and practice dimension than other departments. Systematic and scientific training processes including subtype content and assessment tools are required. Experience still drives nurses' assessments of delirium and subtype. Adding the delirium assessment into routine tasks should be considered.

Abstract
COVID-19 has hit the entire world since late 2019 and is starting to be medically better known. Its clinical presentation is atypical in the elderly. Acute confusion is a sometimes unrecognized warning sign. It is also an element of severity of COVID-19. This viral infection should be systematically investigated for any confusional syndrome in the elderly population.

Abstract
This paper explores the purposeful use of conceptual and methodological tools provided by Cultural Historical Activity Theory (CHAT) to transform learning cultures and practices within and across diverse clinical learning environments. We describe how Change Laboratory methodology helped clinicians and others who support student, intern, and resident education to make changes collaboratively. A case study in undergraduate medical education shows how this created new forms of medical student placement and a postgraduate study shows how it addressed supervisors' undermining behaviour towards Obstetrics and Gynaecology residents. This empirical work illustrates ways of modifying the classical Change Laboratory process to fit local contexts, resources, and needs. We conclude with lessons learned and future directions for practitioner-researchers who wish to broaden the range of methodological tools they use to transform clinical learning environments.

Abstract
Delirium is a common disorder in hospitalized older adults and the defining characteristic is a disturbance of consciousness. Unfortunately, there are currently no testable measures of consciousness as pertains to its disruption in delirium. Not surprisingly rates of recognition of delirium suffer. Arguably, a greater understanding of the quantum of consciousness may improve delirium diagnosis through better diagnostic tools. Candidate dimensions of consciousness derived from fields of psychology, psychiatry, and philosophy are discussed and relevance to delirium explored. Based upon existing literature in the field of consciousness we identify the pre-reflective state, experiential awareness, and functional networks as candidate sites that may be affected in delirium. Opportunities for clinical instrument development and how these tools can be tested are discussed. We conclude that consciousness content may not hold to a unitary measurement, but facets of its integrity that are impacted in delirium are open to further exploration. Disorders in pre-reflective status, experiential awareness, and functional networks may represent the measurable "rabbit holes" of consciousness disturbance.

Abstract
Delirium, a syndrome characterized by an acute change in attention, awareness and cognition, is caused by a medical condition that cannot be better explained by a pre-existing neurocognitive disorder. Multiple predisposing factors (for example, pre-existing cognitive impairment) and precipitating factors (for example, urinary tract infection) for delirium have been described, with most patients having both types. Because multiple factors are implicated in the aetiology of delirium, there are likely several neurobiological processes that contribute to delirium pathogenesis, including neuroinflammation, brain vascular dysfunction, altered brain metabolism, neurotransmitter imbalance and impaired neuronal network connectivity. The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) is the most commonly used diagnostic system upon which a reference standard diagnosis is made, although many other delirium screening tools have been developed given the impracticality of using the DSM-5 in many settings. Pharmacological treatments for delirium (such as antipsychotic drugs) are not effective, reflecting substantial gaps in our understanding of its pathophysiology. Currently, the best management strategies are multidomain interventions that focus on treating precipitating conditions, medication review, managing distress, mitigating complications and maintaining engagement to environmental issues. The effective implementation of delirium detection, treatment and prevention strategies remains a major challenge for health-care organizations globally.
