Psychiatric liaison service referral patterns during the UK COVID-19 pandemic: An observational study.

BACKGROUND AND OBJECTIVES: COVID-19 has had a profound effect on mental health. Liaison psychiatry teams assess and treat people in mental health crises in emergency departments (EDs) and on hospital wards. During the first pandemic wave, new Mental Health Crisis Assessment Services (MHCAS) were created to divert people away from EDs. Our objective was to describe patterns in referrals to psychiatric liaison services across the North Central London care sector (NCL) and explore the impact of a new MHCAS. METHODS: Retrospective study using routinely collected data (ED and ward referrals) from five liaison psychiatry services across NCL (total population 1.5 million people). We described referrals (per week and month) by individual liaison services and cross-sector, and patterns of activity (January 1st 2020 -September 31st 2020, weeks 1-39) compared with the same period in 2019. We calculated changes in the proportion of ED attendees (all-cause) referred to liaison psychiatry. RESULTS: From 2019-2020, total referrals decreased by 16.5% (12,265 to 10,247), a 16.4% decrease in ED referrals (9528 to 7965) and 16.6% decrease in ward referrals (2737 to 2282). There was a marked decrease in referrals during the first pandemic wave (March/April 2020), which increased after lockdown ended. The proportion of ED attendees referred to liaison psychiatry services increased compared to 2019. CONCLUSIONS: People in mental health crisis continued to seek help via ED/MHCAS and a higher proportion of people attending ED were referred to liaison psychiatry services just after the first pandemic wave. MHCAS absorbed some sector ED activity during the pandemic.

Awareness in severe Alzheimer's disease: a systematic review.

Objective: There is limited understanding about how people in the severe stages of Alzheimer's disease (AD) experience and demonstrate awareness. We synthesised all available evidence with the aim of understanding how awareness is preserved or impaired in severe AD and what evidence there is for different levels of awareness according to the levels of awareness framework.Method: A systematic search of the following databases: Embase, PsycINFO, MEDLINE and Web of Science was carried out. A narrative synthesis and analysis was conducted of all included studies. All studies were assessed for quality using the AXIS and CASP tools.Results: Our findings suggest that lower level sensory awareness is relatively maintained in severe AD. Findings for higher level awareness are variable and this may be related to the diversity of methods that have been used to explore awareness in these circumstances.Conclusion: Awareness is complex, heterogeneous and varies significantly between individuals. Environmental and contextual factors have a significant impact on whether awareness is observed in people with severe AD. Adaptation of the environment has the potential to facilitate the expression of awareness while education of caregivers may increase understanding of people with severe AD and potentially improve the quality of care that is received.

Experiences of advance care planning in Parkinson's disease and atypical parkinsonian disorders: a mixed methods systematic review.

BACKGROUND AND PURPOSE: Advance care planning allows people to plan for their future care needs and can include medical, psychological and social aspects. However, little is known on the use, experience of and attitudes towards advance care planning in patients with parkinsonian disorders, their family carers and healthcare professionals. METHODS: A systematic search of online databases was conducted in April 2019 using a narrative synthesis approach with thematic analysis and tabulation to synthesize the findings. RESULTS: In all, 507 articles were identified and 27 were included. There were five overarching themes: (i) what is involved in advance care planning discussions, (ii) when and how advance care planning discussions are initiated, (iii) barriers to advance care planning, (iv) the role of healthcare professionals and (v) the role of the family carer. This evidence was used to highlight eight effective components to support optimal advance care planning in parkinsonian disorders: advance care planning discussions should be individualized in content, timing and approach; patients should be invited to discuss advance care planning early and regularly; palliative care services should be introduced early; a skilled professional should deliver advance care planning; support to family carers should be offered in the advance care planning process; healthcare professionals should be educated on parkinsonian disorders and palliative care; advance care planning should be clearly documented and shared with relevant services; and healthcare professionals should be enabled to conduct effective advance care planning. CONCLUSIONS: These components can inform best practice in advance care planning in patients with parkinsonian disorders.

Healthcare utilization and monetary costs associated with agitation in UK care home residents with advanced dementia: a prospective cohort study.

OBJECTIVE: Nearly half of care home residents with advanced dementia have clinically significant agitation. Little is known about costs associated with these symptoms toward the end of life. We calculated monetary costs associated with agitation from UK National Health Service, personal social services, and societal perspectives. DESIGN: Prospective cohort study. SETTING: Thirteen nursing homes in London and the southeast of England. PARTICIPANTS: Seventy-nine people with advanced dementia (Functional Assessment Staging Tool grade 6e and above) residing in nursing homes, and thirty-five of their informal carers. MEASUREMENTS: Data collected at study entry and monthly for up to 9 months, extrapolated for expression per annum. Agitation was assessed using the Cohen-Mansfield Agitation Inventory (CMAI). Health and social care costs of residing in care homes, and costs of contacts with health and social care services were calculated from national unit costs; for a societal perspective, costs of providing informal care were estimated using the resource utilization in dementia (RUD)-Lite scale. RESULTS: After adjustment, health and social care costs, and costs of providing informal care varied significantly by level of agitation as death approached, from £23,000 over a 1-year period with no agitation symptoms (CMAI agitation score 0-10) to £45,000 at the most severe level (CMAI agitation score >100). On average, agitation accounted for 30% of health and social care costs. Informal care costs were substantial, constituting 29% of total costs. CONCLUSIONS: With the increasing prevalence of dementia, costs of care will impact on healthcare and social services systems, as well as informal carers. Agitation is a key driver of these costs in people with advanced dementia presenting complex challenges for symptom management, service planners, and providers.

Key components of the delirium syndrome and mortality: greater impact of acute change and disorganised thinking in a prospective cohort study.

BACKGROUND: Delirium increases the risk of mortality during an acute hospital admission. Full syndromal delirium (FSD) is associated with greatest risk and subsyndromal delirium (SSD) is associated with intermediate risk, compared to patients with no delirium - suggesting a dose-response relationship. It is not clear how individual diagnostic symptoms of delirium influence the association with mortality. Our objectives were to measure the prevalence of FSD and SSD, and assess the effect that FSD, SSD and individual symptoms of delirium (from the Confusion Assessment Method-short version (s-CAM)) have on mortality rates. METHODS: Exploratory analysis of a prospective cohort (aged ≥70 years) with acute (unplanned) medical admission (4/6/2007-4/11/2007). The outcome was mortality (data censored 6/10/2011). The principal exposures were FSD and SSD compared to no delirium (as measured by the CAM), along with individual delirium symptoms on the CAM. Cox regression was used to estimate the impact FSD and SSD and individual CAM items had on mortality. RESULTS: The cohort (n = 610) mean age was 83 (SD 7); 59% were female. On admission, 11% had FSD and 33% had SSD. Of the key diagnostic symptoms for delirium, 17% acute onset, 19% inattention, 17% disorganised thinking and 17% altered level of consciousness. Unadjusted analysis found FSD had an increased hazard ratio (HR) of 2.31 (95% CI 1.71, 3.12), for SSD the HR was 1.26 (1.00, 1.59). Adjusted analysis remained significant for FSD (1.55 95% CI 1.10, 2.18) but nonsignificant for SSD (HR = 0.92 95% CI 0.70, 1.19). Two CAM items were significantly associated with mortality following adjustment: acute onset and disorganised thinking. CONCLUSION: We observed a dose-response relationship between mortality and delirium, FSD had the greatest risk and SSD having intermediate risk. The CAM items "acute-onset" and "disorganised thinking" drove the associations observed. Clinically, this highlights the necessity of identifying individual symptoms of delirium.

After the Liverpool Care Pathway--development of heuristics to guide end of life care for people with dementia: protocol of the ALCP study.

INTRODUCTION: End of life care guidance for people with dementia is lacking and this has been made more problematic in England with the removal of one of the main end of life care guidelines which offered some structure, the Liverpool Care Pathway. This guidance gap may be eased with the development of heuristics (rules of thumb) which offer a fast and frugal form of decision-making. OBJECTIVE: To develop a toolkit of heuristics (rules of thumb) for practitioners to use when caring for people with dementia at the end of life. METHOD AND ANALYSIS: A mixed-method study using a co-design approach to develop heuristics in three phases. In phase 1, we will conduct at least six focus groups with family carers, health and social care practitioners from both hospital and community care services, using the 'think-aloud' method to understand decision-making processes and to develop a set of heuristics. The focus group topic guide will be developed from the findings of a previous study of 46 interviews of family carers about quality end-of-life care for people with dementia and a review of the literature. A multidisciplinary development team of health and social care practitioners will synthesise the findings from the focus groups to devise and refine a toolkit of heuristics. Phase 2 will test the use of heuristics in practice in five sites: one general practice, one community nursing team, one hospital ward and two palliative care teams working in the community. Phase 3 will evaluate and further refine the toolkit of heuristics through group interviews, online questionnaires and semistructured interviews. ETHICS AND DISSEMINATION: This study has received ethical approval from a local NHS research ethics committee (Rec ref: 15/LO/0156). The findings of this study will be presented in peer-reviewed publications and national and international conferences.

European palliative care guidelines: how well do they meet the needs of people with impaired cognition?

OBJECTIVE: Numbers of people dying with cognitive impairment (intellectual disability (ID), dementia or delirium) are increasing. We aimed to examine a range of European national palliative care guidelines to determine if, and how well, pain detection and management for people dying with impaired cognition are covered. METHODS: Questionnaires were sent to 14 country representatives of the European Pain and Impaired Cognition (PAIC) network who identified key national palliative care guidelines. Data was collected on guideline content: inclusion of advice on pain management, whether cognitively impaired populations were mentioned, assessment tools and management strategies recommended. Quality of guideline development was assessed with the Appraisal of Guidelines Research and Evaluation (AGREE) instrument. RESULTS: 11 countries identified palliative care guidelines, 10 of which mentioned pain management in general. Of these, seven mentioned cognitive impairment (3 dementia, 2 ID and 4 delirium). Half of guidelines recommended the use of pain tools for people with cognitive impairment; recommended tools were not all validated for the target populations. Guidelines from the UK, the Netherlands and Finland included most information on pain management and detection in impaired cognition. Guidelines from Iceland, Norway and Spain scored most highly on AGREE rating in terms of developmental quality. CONCLUSIONS: European national palliative care guidelines may not meet the needs of the growing population of people dying with cognitive impairment. New guidelines should consider suggesting the use of observational pain tools for people with cognitive impairment. Better recognition of their needs in palliative care guidelines may drive improvements in care.

The association between C-reactive protein and delirium in 710 acute elderly hospital admissions.

BACKGROUND: Delirium is a common neuropsychiatric syndrome associated with poor outcomes. Evidence supports a neuroinflammatory etiology, but the role of the inflammatory marker C-reactive protein (C-RP) remains unclear. We investigated the relationship between C-RP and delirium and its severity as well as interaction with medical diagnosis. METHODS: From an existing database (710 patients over 70 years old admitted to a Medical Acute Admissions Unit) we analyzed data which included C-RP levels, delirium (using the Confusion Assessment Method), and other clinical and demographic factors. Primary diagnoses were grouped (cardiovascular, musculoskeletal, infection, metabolic, and other). RESULTS: There was a strong association between elevated C-RP and delirium (t = 5.09; p < 0.001), independent of other potential risk factors for delirium (odds ratio (OR) = 1.32 (95% CI: 1.10-1.58) p = 0.003). There was no significant association between C-RP and delirium severity, and between C-RP and delirium in the populations with cardiovascular disease, infection upon admission, or from the metabolic group despite an OR of 2.24 (95% CI: 0.92-5.45). There was an association in the musculoskeletal group (OR 2.19 (95% CI: 1.19-4.02)). CONCLUSIONS: There is an association between elevated C-RP and delirium. This is strongest in patients admitted with musculoskeletal disease but not in others, implying that C-RP is involved in the genesis of delirium in musculoskeletal disease, but that other factors or processes may be more important in those with cardiovascular disease or infection.

Prospective cohort study of adverse events in older people admitted to the acute general hospital: risk factors and the impact of dementia.

BACKGROUND: Reported adverse events (RAEs) are relatively common in the acute hospital and are associated with significant mortality and morbidity. Dementia is increasing in hospital in-patients, however there have been few studies exploring risk factors for RAEs, in particular cognitive impairment and dementia. Our objective was to identify the prevalence of RAEs in older acute medical inpatients and associated demographic, clinical or cognitive risk factors. METHOD: A longitudinal cohort study set on acute medical wards in a large general hospital. We recruited 710 people aged over 70 years undergoing emergency medical admission. Dementia was diagnosed using operationalised DSM-IV criteria. Patients were assessed using standardised tools including the Confusion Assessment Method, mini-mental state examination, the Functional Assessment Staging scale, the APACHE scale and Charlson co-morbidity index. Data on adverse events was supplied independently by the hospital clinical risk department. RESULTS: 8.6% (95% CI 6.4-10.6) of patients experienced an RAE; 5.9% (95% CI 4.2-7.6) were patient-related and 2.7% (95% CI 1.5-3.8) system-related (incidence rate for all RAEs was 2.1 (95% CI 1.7-2.8)) per person year of hospital admission. Median length of admission was 8 days (inter-quartile range 4-17 days). Patient-related RAEs were associated with male gender, delirium, mild/moderate cognitive impairment and a FAST score of 2-6. Overall, 11.1% died during the admission-this was not associated with experiencing an RAE. Staff comments on incident forms indicated an apparent lack of understanding of the impact of cognitive impairment. CONCLUSIONS: RAEs were common and associated with risk factors identifiable at admission.

'Stockholm syndrome': psychiatric diagnosis or urban myth?

OBJECTIVE: 'Stockholm syndrome' is a term used to describe the positive bond some kidnap victims develop with their captor. High-profile cases are reported by the media although the diagnosis is not described in any international classification system. Here we review the evidence base on 'Stockholm syndrome'. METHOD: Databases (PubMED, EMBASE, PsycINFO, CINAHL) were systematically searched. We compared features of cases widely reported in the English language media to identify common themes which may form a recognizable syndrome. RESULTS: We identified 12 papers that met inclusion criteria. The existing literature consists mostly of case reports; furthermore there is ambiguity in the use of the term. No validated diagnostic criteria have been described. Four common features were found between the five cases studied. CONCLUSION: There is little published academic research on 'Stockholm syndrome' although study of media reports reveals similarities between well publicized cases. This may be due to reporting and publication bias.

A systematic review of the scientific evidence for the efficacy of a palliative care approach in advanced dementia.

BACKGROUND: Patients with dementia often receive poor end-of-life care, with inadequate pain control and without access to the palliative care services that patients with cancer are offered. This has been identified as an area of need in recent UK. Government reports and by the Alzheimer's Society (UK). Our objective was to perform a systematic review of the scientific literature regarding the efficacy of a palliative care model in patients with dementia. METHODS: A systematic review was carried out to identify controlled trials that investigated the efficacy of palliative care in patients with dementia. Data sources included were Medline, EMBASE, PsycINFO, CINAHL, British Nursing Index, AMED, Cochrane Database of Systematic Reviews, Web of Science, Cochrane Central Register of Controlled Trials, International Standard Randomised Controlled Trial register, the NHS Economic Evaluation Database and the System for Information on Grey Literature in Europe. Other data was sourced from hand searches of papers identified on electronic databases and review articles. RESULTS: The search identified 30 review articles, but only four papers were eligible for full appraisal and only two of these met the full criteria for inclusion. These papers gave equivocal evidence of the efficacy for a palliative model of care in dementia. CONCLUSION: Despite the increased interest in palliative care for patients with dementia there is currently little evidence on which to base such an approach. This may in part be due to the ethical difficulties surrounding such research, prognostic uncertainty in clinicians and the lack of clear outcome measures for patients who are unable to express their needs or wishes. Further systematic research is urgently needed to educate an important and developing area of clinical practice.

EEG abnormalities in frontotemporal lobar degeneration.

The EEG appearances in patients with frontotemporal lobar degeneration (FTLD) were compared with those in patients with Alzheimer disease (AD). EEG abnormalities were found in 61% of FTLD patients, with the degree of EEG abnormality increasing with dementia severity. There was no significant difference in the severity of EEG abnormality between the FTLD and AD patient groups. These data suggest a need for reappraisal of the role of the EEG in the diagnostic differentiation of FTLD from AD.

Young onset dementia.

Young onset dementia is a challenging clinical problem with potentially devastating medical and social consequences. The differential diagnosis is wide, and includes a number of rare sporadic and hereditary diseases. However, accurate diagnosis is often possible, and all patients should be thoroughly investigated to identify treatable processes. This review presents an approach to the diagnosis, investigation, and management of patients with young onset dementia, with particular reference to common and treatable causes.

Vulnerability to neuroleptic side effects in frontotemporal lobar degeneration.

BACKGROUND: Frontotemporal lobar degeneration (FTLD) is commonly associated with behavioural disturbances such as disinhibition and aggression; these often result in the use of neuroleptic medication. METHODS: All available case notes of patients attending a specialist cognitive disorders clinic with a diagnosis of FTLD were selected. This gave 100 subjects (62 male, 38 female). RESULTS: In 61 patients significant behavioural disturbances were present. Of these patients, 24 had been prescribed neuroleptics. Significant extrapyramidal side effects were reported in eight patients (33%); in five patients these were severe enough to cause severe mobility problems and in one patient resulted in impaired consciousness. In some instances the extrapyramidal side effects took weeks to wear off. CONCLUSION: These results suggest that patients with FTLD may, as in Lewy body dementia, be particularly sensitive to the extrapyramidal side effects of neuroleptics. We suggest that neuroleptics should be used cautiously in FTLD and treatment should be started at low doses avoiding depot preparations until further prospective studies have been performed.
