Delirium in the acute hospital setting: the role of psychiatry

In this overview we discuss the role of psychiatry in managing delirium in acute hospital admissions. We briefly discuss the role psychiatry can offer in four main domains: (a) assessment; (b) management; (c) recovery; and (d) paradigm, education and research. In the assessment section we discuss accurately detecting delirium in the context of comorbid mixed neuropsychiatric syndromes, including depression and dementia, and the clinical importance of delirium subtyping. The management section briefly outlines pharmacological and non-pharmacological approaches to delirium and their evidence-based rationale. The recovery section focuses on the effect delirium can have on cognitive decline, mental health and long-term health, including functional outcome and need for institutional care after hospital discharge. Finally, we outline the role of psychiatry in delirium research and education. We hope that this article will encourage clinicians to reflect on their current practice and consider holistic and evidence-based care for this vulnerable population in the acute hospital setting.</jats:p

Concepts of mental capacity for patients requesting assisted suicide: a qualitative analysis of expert evidence presented to the Commission on Assisted Dying

BACKGROUND: In May 2013 a new Assisted Dying Bill was tabled in the House of Lords and is currently scheduled for a second reading in May 2014. The Bill was informed by the report of the Commission on Assisted Dying which itself was informed by evidence presented by invited experts. This study aims to explore how the experts presenting evidence to the Commission on Assisted Dying conceptualised mental capacity for patients requesting assisted suicide and examine these concepts particularly in relation to the principles of the Mental Capacity Act 2005. METHODS: This study was a secondary qualitative analysis of 36 transcripts of oral evidence and 12 pieces of written evidence submitted by invited experts to the Commission on Assisted Dying using a framework approach. RESULTS: There was agreement on the importance of mental capacity as a central safeguard in proposed assisted dying legislation. Concepts of mental capacity, however, were inconsistent. There was a tendency towards a conceptual and clinical shift toward a presumption of incapacity. This appeared to be based on the belief that assisted suicide should only be open to those with a high degree of mental capacity to make the decision. The ‘boundaries’ around the definition of mental capacity appeared to be on a continuum between a circumscribed legal ‘cognitive’ definition of capacity (in which most applicants would be found to have capacity unless significantly cognitively impaired) and a more inclusive definition which would take into account wider concepts such as autonomy, rationality, voluntariness and decision specific factors such as motivation for decision making. CONCLUSION: Ideas presented to the Commission on Assisted Dying about mental capacity as it relates to assisted suicide were inconsistent and in a number of cases at variance with the principles of the Mental Capacity Act 2005. Further work needs to be done to establish a consensus as to what constitutes capacity for this decision and whether current legal frameworks are able to support clinicians in determining capacity for this group

Use of Immersive Virtual Reality in the Assessment and Treatment of Alzheimer's Disease: A Systematic Review.

BACKGROUND: Immersive virtual reality (iVR) allows seamless interaction with simulated environments and is becoming an established tool in clinical research. It is unclear whether iVR is acceptable to people with Alzheimer's disease (AD) dementia or useful in their care. We explore whether iVR is a viable research tool that may aid the detection and treatment of AD. OBJECTIVES: This review examines the use of iVR in people with AD or mild cognitive impairment (MCI). METHODS: Medline, PsycINFO, Embase, CINAHL, and Web of Science databases were searched from inception. PRISMA guidelines were used with studies selected by at least two researchers. RESULTS: Nine studies were eligible for inclusion. None reported any issues with iVR tolerability in participants with MCI and AD on assessment or treatment tasks. One study demonstrated capability for detecting prodromal AD and correlated with neuroanatomical substrates. Two studies showed iVR to have high accuracy in differentiating participants with AD from controls but were not hypothesis driven or with adequate controls measures. In a small validation study and two longitudinal case studies, iVR cognitive training was positively rated but did not demonstrate reliable benefit. CONCLUSION: iVR is emerging as a viable method of assessing older adults and people with AD. Strongest benefits were seen when closely integrated with theoretical models of neurodegeneration and existing screening methods. Further randomized controlled trials integrated with clinical populations are required. This will consolidate the power of iVR for assessment of MCI and clarify treatment efficacy beyond current applications in physical rehabilitation

Mortality in dementia with Lewy bodies compared with Alzheimer's dementia: a retrospective naturalistic cohort study.

OBJECTIVES: To use routine clinical data to investigate survival in dementia with Lewy bodies (DLB) compared with Alzheimer's dementia (AD). DLB is the second most common dementia subtype after AD, accounting for around 7% of dementia diagnoses in secondary care, though studies suggest that it is underdiagnosed by up to 50%. Most previous studies of DLB have been based on select research cohorts, so little is known about the outcome of the disease in routine healthcare settings. SETTING: Cambridgeshire & Peterborough NHS Foundation Trust, a mental health trust providing secondary mental health care in England. SAMPLE: 251 DLB and 222 AD identified from an anonymised database derived from electronic clinical case records across an 8-year period (2005-2012), with mortality data updated to May 2015. RESULTS: Raw (uncorrected) median survival was 3.72 years for DLB (95% CI 3.33 to 4.14) and 6.95 years for AD (95% CI 5.78 to 8.12). Controlling for age at diagnosis, comorbidity and antipsychotic prescribing the model predicted median survival for DLB was 3.3 years (95% CI 2.88 to 3.83) for males and 4.0 years (95% CI 3.55 to 5.00) for females, while median survival for AD was 6.7 years (95% CI 5.27 to 8.51) for males and 7.0 years (95% CI 5.92 to 8.73) for females. CONCLUSION: Survival from first presentation with cognitive impairment was markedly shorter in DLB compared with AD, independent of age, sex, physical comorbidity or antipsychotic prescribing. This finding, in one of the largest clinical cohorts of DLB cases assembled to date, adds to existing evidence for poorer survival for DLB versus AD. There is an urgent need for further research to understand possible mechanisms accounting for this finding

Clinical Presentation, Diagnostic Features, and Mortality in Dementia with Lewy Bodies.

BACKGROUND: Dementia with Lewy bodies (DLB) is the second most common degenerative dementia in older people. However, rates of misdiagnosis are high, and little is known of its natural history and outcomes. Very few previous studies have been able to access routine clinical information for large, unbiased DLB cohorts in order to establish initial presentation, neuropsychological profile, and mortality. OBJECTIVE: To examine in detail, symptom patterns at presentation and their association with outcomes, including mortality, in a large naturalistic DLB cohort from a secondary care sample. METHODS: A retrospective cohort design was used to identify a DLB cohort (n = 251) from Cambridgeshire and Peterborough NHS Foundation Trust (CPFT). Information relating to first consultation, diagnosis, and DLB diagnostic features were extracted. RESULTS: A wide range of presenting complaints and differential initial diagnoses were identified for the cohort. Along with memory loss (27.1%) and hallucinations (25.4%), low mood (25.1%) was noted as a key presenting complaint among the DLB cohort. Rates of REM sleep disorder were considerably lower (8.4%) than would be expected. Deficits in non-amnestic cognitive domains were associated with reduced mortality compared with amnestic-only presentations. CONCLUSION: Individuals later diagnosed with DLB present initially to secondary care with a wide range of symptoms and complaints, some of which are not immediately suggestive of a DLB diagnosis. More examinations of large cohorts such as this are needed to further elucidate the complex presentation and clinical course of DLB, and to confirm whether amnestic-only presentation confers a worse outcome.Alzheimer's Society; CPFT; NIHR Cambridge Biomedical Research Centr

Evaluating process and effectiveness of a low-intensity CBT intervention for women with gynaecological cancer (the EPELIT Trial)

This document is the Accepted Manuscript version of a published work that appeared in final form in AMRC Open Research. To access the final edited and published work see https://doi.org/10.12688/amrcopenres.12971.1Background: Improving survival from gynaecological cancers is creating an increasing clinical challenge for long-term distress management. Psychologist-led interventions for cancer survivors can be beneficial, but are often costly. The rise of the Psychological Wellbeing Practitioner (PWP) workforce in the UK might offer a cheaper, but equally effective, intervention delivery method that is more sustainable and accessible. We aimed to test the effectiveness of a PWP co-facilitated intervention for reducing depression and anxiety, quality of life and unmet needs. Methods: We planned this trial using a pragmatic, non-randomised controlled design, recruiting a comparator sample from a second clinical site. The intervention was delivered over six-weekly sessions; data were collected from participants at baseline, weekly during the intervention, and at one-week and three-month follow-up. Logistical challenges meant that we only recruited 8 participants to the intervention group, and 26 participants to the control group. Results: We did not find significant, between-group differences for depression, quality of life or unmet needs, though some differences at follow-up were found for anxiety (p<.001). Analysis of potential intervention mediator processes indicated the potential importance of self-management self-efficacy. Low uptake into the psychological intervention raises questions about (a) patient- driven needs for group-based support, and (b) the sustainability of this intervention programme. Conclusions: This study failed to recruit to target; the under-powered analysis likely explains the lack of significant effects reported, though some trends in the data are of interest. Retention in the intervention group, and low attrition in the control group indicate acceptability of the intervention content and trial design; however a small baseline population rendered this trial infeasible in its current design. Further work is required to answer our research questions, but also, importantly, to address low uptake for psychological interventions in this group of cancer survivors

Epidemiologia kliniczna depresji w opiece paliatywnej i wartość predykcyjna objawów somatycznych &#8212; przekrojowe badanie ankietowe z 4-tygodniowym okresem obserwacji

Celem przedstawionego w niniejszej pracy przekrojowego badania ankietowego było określenie rozpowszechnienia i remisji depresji u pacjentów objętych opieką paliatywną oraz oszacowanie wartości predykcyjnej objawów somatycznych w ustalaniu rozpoznania wspomnianego schorzenia. Z 300 kolejnymi pacjentami przeprowadzono wywiady w ciągu tygodnia od pierwszej oceny diagnostycznej przez pielęgniarkę specjalistyczną z placówki zajmującej się stacjonarną i domową opieką paliatywną w południowym Londynie (Wielka Brytania). Oceny pod kątem występowania depresji dokonywano, korzystając z kwestionariusza PRIME-MD PHQ-9. Obecność objawów somatycznych ustalono na podstawie kwestionariusza oceny jakości życia EORTC-QLQ-C30. Kryteria rozpoznawcze dużego zaburzenia depresyjnego zostały spełnione w przypadku 58 pacjentów [19,3% (15,3&#8211;23,3%)], a kryteria dowolnego zespołu depresyjnego &#8212; w przypadku 109 pacjentów [36,3% (32,3&#8211;40,3%)]. Wśród chorych z dużym zaburzeniem depresyjnym więcej było osób płci męskiej, częściej notowano brak nowotworu złośliwego, dolegliwości bólowe, zły stan ogólny i pragnienie szybkiej śmierci. Spośród chorych z dużym zaburzeniem depresyjnym stwierdzonym na początku badania u 69% (27/39) pacjentów odnotowano remisję depresji 4 tygodnie później. Wśród chorych bez depresji na początku badania u 11% (19/174) osób stwierdzono spełnienie kryteriów tego schorzenia podczas wizyty kontrolnej. Wartości predykcyjne dodatnie zaburzeń snu, obniżonego łaknienia i zmęczenia były niskie (< 24%), natomiast wartości predykcyjne ujemne tych objawów &#8212; wysokie (> 89%). Duże rozpowszechnienie depresji wśród pacjentów objętych opieką paliatywną świadczy o konieczności dokonywania oceny psychologicznej tych osób i udzielania im wsparcia psychologicznego. Przebieg depresji u pacjentów objętych opieką paliatywną charakteryzuje się małą stabilnością, w związku z czym jej objawy powinno się uważnie monitorować

Simulating a Community Mental Health Service During the COVID-19 Pandemic: Effects of Clinician-Clinician Encounters, Clinician-Patient-Family Encounters, Symptom-Triggered Protective Behaviour, and Household Clustering.

Objectives: Face-to-face healthcare, including psychiatric provision, must continue despite reduced interpersonal contact during the COVID-19 (SARS-CoV-2 coronavirus) pandemic. Community-based services might use domiciliary visits, consultations in healthcare settings, or remote consultations. Services might also alter direct contact between clinicians. We examined the effects of appointment types and clinician-clinician encounters upon infection rates. Design: Computer simulation. Methods: We modelled a COVID-19-like disease in a hypothetical community healthcare team, their patients, and patients' household contacts (family). In one condition, clinicians met patients and briefly met family (e.g., home visit or collateral history). In another, patients attended alone (e.g., clinic visit), segregated from each other. In another, face-to-face contact was eliminated (e.g., videoconferencing). We also varied clinician-clinician contact; baseline and ongoing "external" infection rates; whether overt symptoms reduced transmission risk behaviourally (e.g., via personal protective equipment, PPE); and household clustering. Results: Service organisation had minimal effects on whole-population infection under our assumptions but materially affected clinician infection. Appointment type and inter-clinician contact had greater effects at low external infection rates and without a behavioural symptom response. Clustering magnified the effect of appointment type. We discuss infection control and other factors affecting appointment choice and team organisation. Conclusions: Distancing between clinicians can have significant effects on team infection. Loss of clinicians to infection likely has an adverse impact on care, not modelled here. Appointments must account for clinical necessity as well as infection control. Interventions to reduce transmission risk can synergize, arguing for maximal distancing and behavioural measures (e.g., PPE) consistent with safe care

Hospitalization in people with dementia with Lewy bodies: Frequency, duration, and cost implications

Introduction: Increased hospitalization is a major component of dementia impact on individuals and cost, but has rarely been studied in dementia with Lewy bodies (DLB). Our aim was to describe the risk and duration of hospital admissions in patients with DLB, and compare these to those in Alzheimer’s disease (AD) and the general population. Methods: A large database of mental health and dementia care in South London was used to assemble a cohort of patients diagnosed with DLB. These were 1:4 matched with patients diagnosed with AD on age, gender, and cognitive status. Results: Rates of hospital admissions in the year after dementia diagnosis were significantly higher in 194 patients with DLB than in 776 patients with AD (crude incidence rate ratio 1.50; 95% confidence interval: 1.28–1.75) or the catchment population (indirectly standardized hospitalization rate 1.22; 95% confidence interval: 1.06–1.39). Patients with DLB had on average almost four additional hospital days per person-year than patients with AD. Multivariate Poisson regression models indicated poorer physical health early in the disease course as the main driver of this increased rate of hospitalization, whereby neuropsychiatric symptoms additionally explained the higher number of hospital days. Discussion: Patients with DLB are more frequently admitted to general hospitals and utilize inpatient care to a substantially higher degree than patients with AD or the general elderly population. These data highlight an opportunity to reduce hospital days by identifying DLB earlier and providing more targeted care focused on the specific triggers for hospitalization and associations of prolonged stay

Mortality rates and proximal causes of death in patients with Lewy body dementia versus Alzheimer's disease: A longitudinal study using secondary care mental health records

BACKGROUND: Previous studies have shown reduced survival in Lewy body dementia (LBD) compared to Alzheimer's disease (AD), but the reasons for this are not known. We identified cause of death categories accounting for the reduced survival in LBD. METHODS: We linked cohorts of patients with dementia with Lewy bodies (DLB), Parkinson's disease dementia (PDD) and AD, with proximal cause of death data. We examined mortality by dementia group and hazard ratios for each death category by dementia group in males and females separately. In a specific focus on the dementia group with the highest mortality rate versus reference, we examined cumulative incidence to identify the main causes of death accounting for the excess deaths. RESULTS: Hazard ratios for death were higher in PDD and DLB compared to AD, for both males and females. PDD males had the highest hazard ratio for death across the dementia comparison groups (HR 2.7, 95% CI 2.2-3.3). Compared with AD, hazard ratios for "nervous system" causes of death were significantly elevated in all LBD groups. Additional significant cause-of-death categories included aspiration pneumonia, genitourinary causes, other respiratory causes, circulatory and a "symptoms and signs" category in PDD males; other respiratory causes in DLB males; mental disorders in PDD females; and aspiration pneumonia, genitourinary and other respiratory causes in DLB females. CONCLUSION: Further research and cohort development is required to investigate differences by age group, to extend cohort follow-up to the whole population and to investigate the risk-balance of interventions which may differ by dementia group
