Why you should read this article: • To understand the complexity of the needs of people with delirium superimposed on dementia • To enhance your knowledge of second-generation activity theory • To recognise the consequences of the separation of physical health and mental healthcare. Background: Delirium superimposed on dementia (DSD) affects the physical, mental and cognitive well-being of the person. The separation of physical health and mental health means that the care of people with DSD is at odds with the multifaceted aetiology and presentation of the condition. There is a lack of research on DSD from a mental health perspective. Aim: To explore UK mental health nurses’ experiences of providing care for people with DSD. Method: Individual semi-structured interviews were conducted with seven mental health nurses from one NHS trust in England. Participants’ experiences were considered through the lens of second-generation activity theory. Data were analysed using framework analysis. Findings: Six themes were identified: awareness of guidance and tools; guidance or tools as ‘paper exercises’; knowing the patient; the multidisciplinary team; care burden; and mental health versus physical health. Conclusion: When providing care for people with DSD, mental health nurses use their skills in knowing patients as individuals. However, this aspect of ‘knowing’ cannot be readily translated into the use of a numerical scoring tool. An integrated approach is required to support the care of people with DSD.

Introduction Delirium and multiple long-term conditions (MLTC) share numerous risk factors and have been shown individually to be associated with adverse outcomes following hospitalisation. However, the extent to which these common ageing syndromes have been studied together is unknown. This scoping review aims to summarise our knowledge to date on the interrelationship between MLTC and delirium. Methods Searches including terms for delirium and MLTC in adult human participants were performed in PubMed, EMBASE, Medline, Psycinfo and CINAHL. Descriptive analysis was used to summarise findings, structured according to Synthesis Without Meta-analysis reporting guidelines. Results After removing duplicates, 5256 abstracts were screened for eligibility, with 313 full-texts sought along with 17 additional full-texts from references in review articles. In total, 140 met inclusion criteria and were included in the final review. Much of the literature explored MLTC as a risk factor for delirium (n  = 125). Fewer studies explored the impact of MLTC on delirium presentation (n  = 5), duration (n  = 3) or outcomes (n  = 6) and no studies explored how MLTC impacts the treatment of delirium or whether having delirium increases risk of developing MLTC. The most frequently used measures of MLTC and delirium were the Charlson Comorbidity Index (n  = 98/140) and Confusion Assessment Method (n  = 81/140), respectively. Conclusion Existing literature largely evaluates MLTC as a risk factor for delirium. Major knowledge gaps identified include the impact of MLTC on delirium treatment and the effect of delirium on MLTC trajectories. Current research in this field is limited by significant heterogeneity in defining both MLTC and delirium. [ABSTRACT FROM AUTHOR]

Background: Delirium is a serious neuropsychiatric syndrome with adverse outcomes, which is common but often undiagnosed in terminally ill people. The 4 'A's test or 4AT (www.the4AT.com), a brief delirium detection tool, is widely used in general settings, but validation studies in terminally ill people are lacking. Aim: To determine the diagnostic accuracy of the 4AT in detecting delirium in terminally ill people, who are hospice inpatients. Design: A diagnostic test accuracy study in which participants underwent the 4AT and a reference standard based on the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. The reference standard was informed by Delirium Rating Scale Revised-98 and tests assessing arousal and attention. Assessments were conducted in random order by pairs of independent raters, blinded to the results of the other assessment. Setting/participants: Two hospice inpatient units in Scotland, UK. Participants were 148 hospice inpatients aged ⩾18 years. Results: A total of 137 participants completed both assessments. Three participants had an indeterminate reference standard diagnosis and were excluded, yielding a final sample of 134. Mean age was 70.3 (SD = 10.6) years. About 33% (44/134) had reference standard delirium. The 4AT had a sensitivity of 89% (95% CI 79%–98%) and a specificity of 94% (95% CI 90%–99%). The area under the receiver operating characteristic curve was 0.97 (95% CI 0.94–1). Conclusion: The results of this validation study support use of the 4AT as a delirium detection tool in hospice inpatients, and add to the literature evaluating methods of delirium detection in palliative care settings.

Despite increasing early rehabilitation and mobilisation (ERM) in paediatric intensive care, current evidence for ERM of neonatal and paediatric patients receiving extracorporeal membrane oxygenation (ECMO) is limited. The proposed benefits of ERM in neonatal and paediatric ECMO patients are multifaceted, including reduced immobility related issues and maintenance of functional ability. However, ECMO presents additional safety and logistical challenges, and currently there are no published neonatal or paediatric guidelines. A consensus document was developed to provide guidance for ERM with neonatal and paediatric ECMO patients. The document was developed by specialist physiotherapists from nine ECMO centres within the UK and Ireland, together with the UK Paediatric Critical Care Society ECMO group and members of the multidisciplinary team. The document covers key considerations and practicalities for completing ERM in this population including, acuity level measurement, activity level guidance, safety and risk assessment, and goal setting. Risk assessment and safety checklist bedside tools are also included and designed to be adapted as required to meet specific unit policies and protocols. [ABSTRACT FROM AUTHOR]

Major depression (MD) is a well-recognized risk factor for delirium. However, observational studies cannot provide direct evidence of causality between MD and delirium. This study explored the genetic causal association between MD and delirium using two-sample Mendelian randomization (MR). Genome-wide association study (GWAS) summary data for MD were obtained from the UK Biobank. GWAS summary data for delirium were obtained from the FinnGen Consortium. Inverse-variance weighted (IVW), MR Egger, weighted median, simple mode, and weighted mode were used to perform the MR analysis. In addition, the Cochrane's Q test was used to detect heterogeneity in the MR results. Horizontal pleiotropy was detected using the MR-Egger intercept test and MR pleiotropy residual sum and outliers (MR-PRESSO) test. Leave-one-out analysis was used to investigate the sensitivity of this association. The IVW method showed that MD was an independent risk factor for delirium (P = 0.013). Horizontal pleiotropy was unlikely to bias causality (P > 0.05), and no evidence of heterogeneity was found between the genetic variants (P > 0.05). Finally, a leave-one-out test showed that this association was stable and robust. All participants included in the GWAS were of European ancestry. Due to database limitations, the MR analysis did not conduct stratified analyses for different countries, ethnicities, or age groups. We conducted a two-sample MR analysis and found the evidence of genetic causal association between MD and delirium. • A two-sample MR analysis was conducted to explore the causal effect between MD and delirium. • Inverse-variance weighted, MR Egger, weighted median, simple mode, and weighted mode were used to perform the MR analysis. • Heterogeneity and horizontal pleiotropy in the MR results were detected. • We found the evidence of genetic causal association between MD and delirium.

Background: Delirium affects over 20% of all hospitalised older adults. Delirium is associated with a number of adverse outcomes following hospital admission including cognitive decline, anxiety and depression, increased mortality and care needs. Previous research has addressed prevention of delirium in hospitals and care homes, and there are guidelines on short-term treatment of delirium during admission. However, no studies have addressed the problem of longer-term recovery after delirium and it is currently unknown whether interventions to improve recovery after delirium are effective and cost-effective. The primary objective of this feasibility study is to test a new, theory-informed rehabilitation intervention (RecoverED) in older adults delivered following a hospital admission complicated by delirium to determine whether (a) the intervention is acceptable to individuals with delirium and (b) a definitive trial and parallel economic evaluation of the intervention are feasible. Methods: The study is a multi-centre, single-arm feasibility study of a rehabilitation intervention with an embedded process evaluation. Sixty participants with delirium (aged > 65 years old) and carer pairs will be recruited from six NHS acute hospitals across the UK. All pairs will be offered the intervention, with follow-up assessments conducted at 3 months and 6 months post-discharge home. The intervention will be delivered in participants' own homes by therapists and rehabilitation support workers for up to 10 intervention sessions over 12 weeks. The intervention will be tailored to individual needs, and the chosen intervention plan and goals will be discussed and agreed with participants and carers. Quantitative data on reach, retention, fidelity and dose will be collected and summarised using descriptive statistics. The feasibility outcomes that will be used to determine whether the study meets the criteria for progression to a definitive randomised controlled trial (RCT) include recruitment, delivery of the intervention, retention, data collection and acceptability of outcome measures. Acceptability of the intervention will be assessed using in-depth, semi-structured qualitative interviews with participants and healthcare professionals. Discussion: Findings will inform the design of a pragmatic multi-centre RCT of the effectiveness and cost-effectiveness of the RecoverED intervention for helping the longer-term recovery of people with delirium compared to usual care. Trial registration: The feasibility study was registered: ISRCTN15676570 [ABSTRACT FROM AUTHOR]

Background: Post-operative delirium (POD) is an acute brain failure which may occur following major surgery, with serious implications for participants and caregivers. Evidence regarding optimal anaesthetic management for older participants at higher risk of POD is conflicting. We conducted a feasibility study of our protocol in 5 centres to guide sample size estimation and inform future recruitment strategies for a larger cohort study. Methods: Participants aged over 65 and scheduled for major surgery were recruited. They were assessed pre-operatively for delirium, cognitive impairment, depression, comorbidity, activity levels and alcohol use. Details of management during surgery, all medications and complications were recorded by a trainee-led research team. Participants were assessed for delirium in the immediate recovery period and then on post-operative days 1–4 using the 4 question attention test (4AT) with complications assessed at day 4 using the post-operative morbidity survey (POMS). Primary outcomes were the incident rates of POD. Secondary outcomes were number of eligible patients, recruitment rates and retention rates throughout the study, time required for data collection, preoperative risk factors assessment and daily postoperative delirium assessments. Also to assess the added value of employing the regional trainee research network (INCARNNET) to deliver the study. Specifically, what proportion of patient consent, data collection and post-operative testing is performed by anaesthesia trainees from this group, especially the success of weekend delirium assessment by trainees? A survey was completed at the end of the study by the trainees involved regarding their involvement in the study. Results: Ninety-five participants were recruited, of whom 93 completed the study. Overall, POD occurred in 9 patients. Of these, three were detected in recovery and six on post-op days 1–4. Median length of stay was 6 days. Recruitment rates were high in all but one site. 59 (62%) participants were consented by trainees and 189 (63%) of post op delirium assessments were performed by trainees. A total of six patients declined the study (in a follow up survey of trainees). Pre-existing cognitive impairment, depression and problem drinking were detected in 4(4.3%), 3(3.2%) and 5(5.37%) participants, respectively. Co-morbidity was common with 55(59%) in class three or four of the geriatric index of morbidity. Overall, from a total of 641 data points, levels of missing data were as follows, site A = 9.3%, B = 13.5%, C = 15.4%, D = 10.9%, E = 11.1% (data could not be completed retrospectively). Conclusions: A multi-centre observational cohort study of delirium carried out by UK trainee anaesthetists is feasible. Patients are content to undergo day of surgery consent and multiple short questionnaires pre-operatively. Proposed data, especially pharmacological, should be carefully considered for their relevance to modifiable mechanisms that can lead to POD. Future research to enable prognostic modelling of POD should involve large scale cohort studies of enriched populations to capture a higher POD incidence. POD remains a common complication in older persons undergoing major surgery in the UK and studies of interventions are urgently needed. Trial registration: All methods were carried out in accordance with relevant guidelines and regulations. The study was retrospectively registered with ISRCTN94663125 on 07/02/2018.

Objective: Delirium is a complex neurocognitive syndrome suspected to be bidirectionally linked to dementia. Circadian rhythm disturbances likely contribute to dementia pathogenesis, but whether these disturbances are related to delirium risk and progression to all‐cause dementia is unknown. Methods: We analyzed continuous actigraphy data from 53,417 middle‐aged or older UK Biobank participants during a median 5 years of follow‐up. Four measures were used to characterize the 24‐hour daily rest–activity rhythms (RARs): normalized amplitude, acrophase representing the peak activity time, interdaily stability, and intradaily variability (IV) for fragmentation of the rhythm. Cox proportional hazards models examined whether RARs predicted incident delirium (n = 551) and progression to dementia (n = 61). Results: Suppressed 24‐hour amplitude, lowest (Q1) versus highest (Q4) quartile (hazard ratio [HR]Q1 vs Q4 = 1.94, 95% confidence interval [CI] = 1.53–2.46, p < 0.001), and more fragmented (higher IV: HRQ4 vs Q1 = 1.49, 95% CI = 1.18–1.88, p < 0.001) rhythms predicted higher delirium risk, after adjusting for age, sex, education, cognitive performance, sleep duration/disturbances, and comorbidities. In those free from dementia, each hour of delayed acrophase was associated with delirium risk (HR = 1.13, 95% CI = 1.04–1.23, p = 0.003). Suppressed 24‐hour amplitude was associated with increased risk of progression from delirium to new onset dementia (HR = 1.31, 95% CI = 1.03–1.67, p = 0.03 for each 1‐standard deviation decrease). Interpretation: Twenty‐four‐hour daily RAR suppression, fragmentation, and potentially delayed acrophase were associated with delirium risk. Subsequent progression to dementia was more likely in delirium cases with suppressed rhythms. The presence of RAR disturbances before delirium and prior to progression to dementia suggests that these disturbances may predict higher risk and be involved in early disease pathogenesis.

Introduction: Delirium is an acute neuro‐psychiatric disturbance precipitated by a range of physical stressors, with high morbidity and mortality. Little is known about its relationship with severe mental illness (SMI). Methods: We conducted a retrospective cohort study using linked data analyses of the UK Clinical Practice Research Datalink (CPRD) and Hospital Episodes Statistics (HES) databases. We ascertained yearly hospital delirium incidence from 2000 to 2017 and used logistic regression to identify associations with delirium diagnosis in a population with SMI. Results: The cohort included 249,047 people with SMI with median follow‐up time in CPRD of 6.4 years. A total of 85,979 patients were eligible for linkage to HES. Delirium incidence increased from 0.04 (95% CI 0.02–0.07) delirium associated admissions per 100 person‐years in 2000 to 1.05 (95% CI 0.93–1.17) per 100 person‐years in 2017, increasing most notably from 2010 onwards. Delirium was associated with older age at study entry (OR 1.05 per year, 95% CI 1.05–1.06), SMI diagnosis of bipolar affective disorder (OR 1.66, 95% CI 1.44–1.93) or other psychosis (OR 1.56, 95% CI 1.35–1.80) relative to schizophrenia, and more physical comorbidities (OR 1.08 per additional comorbidity of the Charlson Comorbidity Index, 95% CI 1.02–1.14). Patients with delirium received more antipsychotic medication during follow‐up (1–2 antipsychotics OR 1.65, 95% CI 1.44–1.90; >2 antipsychotics OR 2.49, 95% CI 2.12–2.92). Conclusions: The incidence of recorded delirium diagnoses in people with SMI has increased in recent years. Older people prescribed more antipsychotics and with more comorbidities have a higher incidence. Linked electronic health records are feasible for exploring hospital diagnoses such as delirium in SMI. [ABSTRACT FROM AUTHOR]

Background: In 2010, a national enquiry into elderly patient outcomes after surgery identified that only 36% received 'good' care. Guidance was subsequently published by the Association of Anaesthetists of Great Britain and Ireland regarding perioperative care of the elderly and those with dementia; this study aims to assess current adherence to these guidelines in anaesthetic departments across Scotland. Methods: A web-based survey was sent to all Scottish departments. The questions assessed department patient demographic, access to specialist pre-assessment services, availability of multidisciplinary input, perioperative care of patients with cognitive impairment and departmental training on geriatric perioperative care. Results: Responses were collected from November-December 2020 with a 92.6% response rate. A total of 64% of departments stated that > 50% of their workload involved patients over 75. One department had a lead clinician for geriatric anaesthesia, whilst 20% could access a geriatric specialist when coordinating perioperative care. Specialist geriatric pre-assessment services operate in 20% of centres. A total of 60% of respondents used a clinical frailty score when pre-assessing patients over 75, with 48% specifically screening for cognitive impairment. The vast majority of centres, 76%, did not routinely provide information regarding post-operative delirium and 24% 'never or very rarely' invite caregivers to accompany patients with dementia into the department. Education sessions regarding perioperative elderly care had occurred in 56% of departments. Conclusions: Elderly patients represent a significant proportion of anaesthetic workload in Scotland. Despite this, adherence to recommended practice is low. The vast majority of centres lack access to specialist multidisciplinary input or specialist pre-assessment services which are essential to providing good care. Reported screening for frailty and cognitive impairment is variable, with opportunities for improvement in communication and education (patient and clinician) surrounding these conditions.

Background Studies investigating outcomes of delirium using large-scale routine data are rare. We performed a two-centre study using the 4 'A's Test (4AT) delirium detection tool to analyse relationships between delirium and 30-day mortality, length of stay and home time (days at home in the year following admission). Methods The 4AT was performed as part of usual care. Data from emergency admissions in patients ≥65 years in Lothian, UK (n  = 43,946) and Salford, UK (n  = 38,824) over a period of |$\sim$| 3 years were analysed using logistic regression models adjusted for age and sex. Results 4AT completion rates were 77% in Lothian and 49% in Salford. 4AT scores indicating delirium (≥4/12) were present in 18% of patients in Lothian, and 25% of patients in Salford. Thirty-day mortality with 4AT ≥4 was 5.5-fold greater than the 4AT 0/12 group in Lothian (adjusted odds ratio (aOR) 5.53, 95% confidence interval [CI] 4.99–6.13) and 3.4-fold greater in Salford (aOR 3.39, 95% CI 2.98–3.87). Length of stay was more than double in patients with 4AT scores of 1–3/12 (indicating cognitive impairment) or ≥ 4/12 compared with 4AT 0/12. Median home time at 1 year was reduced by 112 days (Lothian) and 61 days (Salford) in the 4AT ≥4 group (P  < 0.001). Conclusions Scores on the 4AT used at scale in practice are strongly linked with 30-day mortality, length of hospital stay and home time. The findings highlight the need for better understanding of why delirium is linked with poor outcomes and also the need to improve delirium detection and treatment. [ABSTRACT FROM AUTHOR]

Background: Delirium is a distressing neurocognitive disorder recently linked to sleep disturbances. However, the longitudinal relationship between sleep and delirium remains unclear. This study assessed the associations of poor sleep burden, and its trajectory, with delirium risk during hospitalization.Methods: About 321 818 participants from the UK Biobank (mean age 58 ± 8 years [SD]; range 37-74 years) reported (2006-2010) sleep traits (sleep duration, excessive daytime sleepiness, insomnia-type complaints, napping, and chronotype-a closely related circadian measure for sleep timing), aggregated into a sleep burden score (0-9). New-onset delirium (n = 4 775) was obtained from hospitalization records during a 12-year median follow-up. About 42 291 (mean age 64 ± 8 years; range 44-83 years) had repeat sleep assessment on average 8 years after their first.Results: In the baseline cohort, Cox proportional hazards models showed that moderate (aggregate scores = 4-5) and severe (scores = 6-9) poor sleep burden groups were 18% (hazard ratio = 1.18 [95% confidence interval: 1.08-1.28], p < .001) and 57% (1.57 [1.38-1.80], p < .001), more likely to develop delirium, respectively. The latter risk magnitude is equivalent to 2 additional cardiovascular risks. These findings appeared robust when restricted to postoperative delirium and after exclusion of underlying dementia. Higher sleep burden was also associated with delirium in the follow-up cohort. Worsening sleep burden (score increase ≥2 vs no change) further increased the risk for delirium (1.79 [1.23-2.62], p = .002) independent of their baseline sleep score and time lag. The risk was highest in those younger than 65 years at baseline (p for interaction <.001).Conclusion: Poor sleep burden and worsening trajectory were associated with increased risk for delirium; promotion of sleep health may be important for those at higher risk.

Background delirium is an acute severe neuropsychiatric condition associated with adverse outcomes, particularly in older adults. However, it is frequently under-recognised. Methods this multi-centre quality improvement project utilised a collaborative approach to implementation of changes at sites, with the aim to improve delirium screening, recognition and documentation on discharge summaries. Resources, including delirium guidelines and presentations, were shared between sites, and broad details of local interventions were collected. Three timepoints of data collection (14 March 2018, 14 September 2018 and 13 March 2019) were conducted to assess screening, recognition and documentation of delirium in unscheduled admissions of adults aged ≥65 years old. The impact of local interventions and site-specific factors was assessed using logistic regression analysis, adjusting for patient factors. Results a total of 3,013 patients (mean age 80.2, 53.8% females) were recruited across the three timepoints. Screening for delirium was associated with increased odds of recognition (aOR 4.75, CI 2.98–7.56; P  < 0.001); this was not affected by grade/profession of screener. Rates of screening, recognition and discharge documentation improved across the three timepoints of data collection. The presence of a local delirium specialist team was associated with increased rates of screening for delirium (aOR 1.75, CI 1.41–2.18; P  < 0.001), and the presence of a geriatric medicine team embedded into the admissions unit was associated with increased recognition rates (aOR 1.78, CI 1.09–2.92; P  = 0.022). Conclusion delirium screening is associated with improved recognition. Interventions that strive to improve screening within a culture of delirium awareness are encouraged. [ABSTRACT FROM AUTHOR]

Delirium is one of the most commonly occurring postoperative complications in older adults. It occurs due to the vulnerability of cerebral functioning to pathophysiological stressors. Identification of those at increased risk of developing delirium early in the surgical pathway provides an opportunity for modification of predisposing and precipitating risk factors and effective shared decision-making. No single delirium prediction tool is used widely in surgical settings. Multi-component interventions to prevent delirium involve structured risk factor modification supported by geriatrician input; these are clinically efficacious and cost effective. Barriers to the widespread implementation of such complex interventions exist, resulting in an 'implementation gap'. There is a lack of evidence for pharmacological prophylaxis for the prevention of delirium. Current evidence suggests that avoidance of peri-operative benzodiazepines, careful titration of anaesthetic depth guided by processed electroencephalogram monitoring and treatment of pain are the most effective strategies to minimise the risk of delirium. Addressing postoperative delirium requires a collaborative, whole pathway approach, beginning with the early identification of those patients who are at risk. The research agenda should continue to examine the potential for pharmacological prophylaxis to prevent delirium while also addressing how successful models of delirium prevention can be translated from one setting to another, underpinned by implementation science methodology.

Purpose: This essay was written as a university assignment for an expert dementia practice module as part of the Masters in Applied Professional Practice. This paper aims to provide a critical discussion of the recognition and management of delirium superimposed on dementia. Design/methodology/approach: The findings of this paper showed that the recognition of delirium superimposed of dementia is not well recognized, but early intervention and management can result in preferential outcomes. This requires the use of appropriate recognition tools and for all health-care staff to have specific training within this area. Findings: Education is imperative to improving delirium recognition. Research limitations/implications: Education is imperative to improving awareness. Practical implications: The research implications of this paper demonstrate that appropriate training and education of health-care staff is imperative for the timely recognition of delirium and the improvement of care. Originality/value: This paper was undertaken as an assignment for the University of Highlands and Islands. [ABSTRACT FROM AUTHOR]

Background: Contemporary environmental health investigations have identified green space as an emerging factor with promising prospects for bolstering human well-being. The incidence of delirium increases significantly with age and is fatal. To date, there is no research elucidating the enduring implications of green spaces on the occurrence of delirium. Therefore, we explored the relationship between residential greenness and the incidence of delirium in a large community sample from the UK Biobank., Methods: Enrollment of participants spanned from 2006 to 2010. Assessment of residential greenness involved the land coverage percentage of green space within a buffer range of 300 m and 1000 m. The relationship between residential greenness and delirium was assessed using the Cox proportional hazards model. Further, we investigated the potential mediating effects of physical activity, particulate matter (PM) with diameters ≤2.5 (PM 2.5 ), and nitrogen oxides (NO x )., Results: Of 232,678 participants, 3722 participants were diagnosed with delirium during a 13.4-year follow-up period. Compared with participants with green space coverage at a 300 m buffer in the lowest quartile (Q1), those in the highest quartile (Q4) had 15 % (Hazard ratio [HR] = 0.85, 95 % confidence interval [CI]: 0.77, 0.94) lower risk of incident delirium. As for the 1000 m buffer, those in Q4 had a 16 % (HR = 0.84, 95 % CI: 0.76, 0.93) lower risk of incident delirium. The relationship between green space in the 300 m buffer and delirium was mediated partially by physical activity (2.07 %) and PM 2.5 (49.90 %). Comparable findings were noted for the green space percentage within the 1000 m buffer., Conclusions: Our results revealed that long-term exposure to residential greenness was related to a lower risk of delirium. Air pollution and physical activity exerted a significant mediating influence in shaping this association., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Yueping Shen reports financial support was provided by National Natural Science Foundation of China.

Older adults constitute a large proportion of patients undergoing surgery and present with complexity, predisposing them to adverse postoperative outcomes. Inequalities exist in the provision of surgical care across the United Kingdom evidenced by increased waiting times in areas of social deprivation, a disparity in the provision of surgical care across geographic locations as well as a variation in the medical management of comorbidities in surgical patients. Addressing inequalities in the delivery of perioperative care for older adults necessitates a multi-faceted approach. It requires implementation of an evidence-based approach to optimisation of older surgical adults using Comprehensive Geriatric Assessment and optimisation methodology at scale, development of an age-attuned, flexible, transdisciplinary workforce, a restructuring of funding to commission services addressing the needs of the older surgical population and a change in culture and professional and public understanding of the needs of the older surgical patient.

Objectives: During the coronavirus disease (COVID-19) pandemic, patients with altered mental status (AMS: dementia, delirium and delirium superimposed on dementia) were profoundly affected by an abrupt transformation in healthcare systems. Here, we evaluated quality-care outcomes, including length of stay (LOS), in-hospital mortality, early readmission and mortality after hospital discharge, in older adults admitted for AMS during the pandemic and compared them to patients admitted prior to the pandemic., Methods: Chi-squared and Fisher's exact tests were used to examine changes to admissions for AMS before and during the pandemic, and their outcomes. Logistic regression analyses, with reference to pre-pandemic data, were conducted to examine the impact of the pandemic on outcomes., Design: Prospective data of 21,192 non-COVID admissions to an acute general medical department in a Surrey (UK) hospital were collected from patients admitted before (1st April 2019 to 29th February 2020) and during the pandemic (1st March 2020 to 31st March 2021)., Results: There were 10,173 (47.7% men) from the pre-pandemic and 11,019 (47.5% men) from the pandemic periods; overall mean age  =  68.3yr. During the pandemic AMS patients had significantly higher admission rates (1.1% vs 0.6%, P < 0.001). However, median LOS in hospital was shorter (9.0 days [IQR = 5.3-16.2] vs 15.5 days [IQR  =  6.2-25.7], P < 0.001) and thus were less likely to stay in hospital >3 weeks: adjusted OR  =  0.26 (95%CI  =  0.12-0.57). In-hospital mortality and readmission within 28 days of discharge did not change during the pandemic, but were less likely to die within 30 days of discharge: adjusted OR = 0.32 (95%CI = 0.11-0.96)., Conclusions: This combination of higher admission rate, shorter LOS, and an unchanging early readmission suggests a higher admission-discharge turnover of different patients with AMS and provides important insights into the potential impact of the COVID-19 pandemic on healthcare delivery to individuals with AMS., (© 2024 The Author(s).

Background: The objective of this study was to analyze the impact of a structured educational intervention on the implementation of guideline-recommended pain, agitation, and delirium (PAD) assessment., Methods: This was a prospective, multinational, interventional before-after trial conducted at 12 intensive care units from 10 centers in Germany, Austria, Switzerland, and the UK. Intensive care units underwent a 6-week structured educational program, comprising online lectures, instructional videos, educational handouts, and bedside teaching. Patient-level PAD assessment data were collected in three 1-day point-prevalence assessments before (T1), 6 weeks after (T2), and 1 year after (T3) the educational program., Results: A total of 430 patients were included. The rate of patients who received all three PAD assessments changed from 55% (107/195) at T1 to 53% (68/129) at T2, but increased to 73% (77/106) at T3 (p = 0.003). The delirium screening rate increased from 64% (124/195) at T1 to 65% (84/129) at T2 and 77% (82/106) at T3 (p = 0.041). The pain assessment rate increased from 87% (170/195) at T1 to 92% (119/129) at T2 and 98% (104/106) at T3 (p = 0.005). The rate of sedation assessment showed no signficiant change. The proportion of patients who received nonpharmacological delirium prevention measures increased from 58% (114/195) at T1 to 80% (103/129) at T2 and 91% (96/106) at T3 (p < 0.001). Multivariable regression revealed that at T3, patients were more likely to receive a delirium assessment (odds ratio [OR] 2.138, 95% confidence interval [CI] 1.206-3.790; p = 0.009), sedation assessment (OR 4.131, 95% CI 1.372-12.438; p = 0.012), or all three PAD assessments (OR 2.295, 95% CI 1.349-3.903; p = 0.002) compared with T1., Conclusions: In routine care, many patients were not assessed for PAD. Assessment rates increased significantly 1 year after the intervention. Clinical trial registration ClinicalTrials.gov: NCT03553719., (© 2023. The Author(s).)

This article critically analyses the prevalence, assessment and management of urinary tract infections (UTIs) in patients over the age of 65, in an urgent care out-of-hours service in order to enhance care. It is undertaken from the perspective of working as an Advanced Nurse Practitioner (ANP). A synopsis of UTI is presented, examining the epidemiology and aetiology. The process of assessment, diagnosis and management of UTI in older people is appraised based on current evidence. Difficulties associated with the recognition of UTI in elderly are evaluated. Finally, recommendations are made for the improvement of future practice as an ANP. [ABSTRACT FROM AUTHOR]

BACKGROUND/OBJECTIVES: Delirium is common in older adults, especially following hospitalization. Because low vitamin D levels may be associated with increased delirium risk, we aimed to determine the prognostic value of blood vitamin D levels, extending our previous genetic analyses of this relationship. DESIGN: Prospective cohort analysis. SETTING: Community‐based cohort study of adults from 22 cities across the United Kingdom (the UK Biobank). PARTICIPANTS: Adults aged 60 and older by the end of follow‐up in the linked hospital inpatient admissions data, up to 14 years after baseline (n = 351,320). MEASUREMENTS: At baseline, serum vitamin D (25‐OH‐D) levels were measured. We used time‐to‐event models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between vitamin D deficiency and incident hospital‐diagnosed delirium, adjusted for age, sex, assessment month, assessment center, and ethnicity. We performed Mendelian randomization genetic analysis in European participants to further investigate vitamin D and delirium risk. RESULTS: A total of 3,634 (1.03%) participants had at least one incident hospital‐diagnosed delirium episode. Vitamin D deficiency (<25 nmol/L) predicted a large incidence in delirium (HR = 2.49; 95% CI = 2.24–2.76; P = 3*10−68, compared with >50 nmol/L). Increased risk was not limited to the deficient group: insufficient levels (25–50 nmol/L) were also at increased risk (HR = 1.38; 95% CI = 1.28–1.49; P = 4*10−18). The association was independent of calcium levels, hospital‐diagnosed fractures, dementia, and other relevant cofactors. In genetic analysis, participants carrying more vitamin D–increasing variants had a reduced likelihood of incident delirium diagnosis (HR =.80 per standard deviation increase in genetically instrumented vitamin D:.73–.87; P = 2*10−7). CONCLUSION: Progressively lower vitamin D levels predicted increased risks of incident hospital‐diagnosed delirium, and genetic evidence supports a shared causal pathway. Because low vitamin D levels are simple to detect and inexpensive and safe to correct, an intervention trial to confirm these results is urgently needed. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 pandemic led to changes in the way that healthcare was accessed and delivered in the United Kingdom (UK), particularly during the peak of the first lockdown period (the "first wave") beginning in March 2020. In some patients, COVID-19 is associated with acute neuropsychiatric manifestations, and there is suggestion that there may also be longer term neuropsychiatric complications. Despite this, at the time of writing there are only emerging data on the direct effects of the COVID-19 pandemic on psychiatric care. Methods: In this retrospective study we analyzed referrals to an inpatient liaison psychiatry department of a large acute teaching hospital during the first wave of covid-19 in the UK and compared this data to the same period in 2019. Results: We saw a 40% reduction in the number of referrals in 2020, with an increase in the proportion of referrals for both psychosis or mania and delirium. Almost one third (28%) of referred patients tested positive for COVID-19 at some point during their admission, with 40% of these presenting with delirium as a consequence of their COVID-19 illness. Save delirium, we did not find evidence for high prevalence of new-onset acute mental illness in COVID-19 positive patients. Conclusion: Our data indicate decreased clinical activity in our inpatient psychiatry liaison department during the first wave of the COVID-19 pandemic, although a relative increase in relative increase in referrals for psychosis or mania, suggesting less of a relative decrease in more severe cases of mental illness. The reasons for this are likely multifactorial, including structural changes in the NHS and patient reluctance to present to emergency departments (ED) due to infection fears and Government advice. Our data also supports the literature suggesting the high relative prevalence of delirium in COVID-19, and we support integration of psychiatry liaison teams in acute general hospital wards to optimize delirium management. Finally, consideration should be given to adequate staffing of community and crisis mental health teams to safely manage the mental health of people reluctant to visit EDs. [ABSTRACT FROM AUTHOR]

The unexpected emergence and spread of coronavirus disease 2019 (COVID-19) has been pandemic, with long-lasting effects, and unfortunately, it does not seem to have ended. Integrating advanced planning, strong teamwork, and clinical management have been both essential and rewarding during this time. Understanding the new concepts of this novel disease and accommodating them into clinical practice is an ongoing process, ultimately leading to advanced and highly specific treatment modalities. We conducted a literature review through PubMed, Europe PMC, Scopus, and Google Scholar to incorporate the most updated therapeutic principles. This article provides a concise and panoramic view of the cohort of critically ill patients admitted to the intensive care unit. We conclude that COVID-19 management includes low tidal volume ventilation, early proning, steroids, and a high suspicion for secondary bacterial/fungal infections. Lung ultrasound is emerging as a promising tool in assessing the clinical response. Managing non-clinical factors such as staff burnout, communication/consent issues, and socio-emotional well-being is equally important. [ABSTRACT FROM AUTHOR]

Background: Atypical presentations of COVID‐19 pose difficulties for early isolation and treatment, particularly in institutional care settings. We aimed to characterize the presenting symptoms and associated mortality of COVID‐19 in older adults, focusing on care home residents admitted to secondary care. Methods: A retrospective cohort study of 134 consecutive inpatients over 80 years old hospitalized with PCR confirmed COVID‐19 in the United Kingdom. Symptoms at presentation and frailty were analysed. Differences between community dwelling and care home residents, and associations with mortality, were assessed using between‐group comparisons and logistic regression. Results: Care home residents were less likely to experience cough (46.9% vs 72.9%, P =.002) but more likely to present with delirium (51.6% vs 31.4%, P =.018), particularly hypoactive delirium (40.6% vs 24.3%, P =.043). Mortality was more likely with increasing frailty (OR 1.25, 95% CI 1.00, 1.58, P =.049) and those presenting with anorexia (OR 3.20, 95% CI 1.21, 10.09, P =.028). There were no differences in mortality or length of stay based on residential status. Conclusion: COVID‐19 in older adults often presents with atypical symptoms, particularly in those admitted from institutional care. These individuals have a reduced incidence of cough and increased hypoactive delirium. Individuals presenting atypically, especially with anorexia, have higher mortality. [ABSTRACT FROM AUTHOR]

Background: The literature contains limited information on the problems faced by dying patients with COVID-19 and the effectiveness of interventions to manage these. Aim: The aim of this audit was to assess the utility of our end-of-life care plan, and specifically the effectiveness of our standardised end-of-life care treatment algorithms, in dying patients with COVID-19. Design: The audit primarily involved data extraction from the end-of-life care plan, which includes four hourly nursing (ward nurses) assessments of specific problems: patients with problems were managed according to standardised treatment algorithms, and the intervention was deemed to be effective if the problem was not present at subsequent assessments. Setting/participants: This audit was undertaken at a general hospital in England, covered the 8 weeks from 16 March to 11 May 2020 and included all inpatients with COVID-19 who had an end-of-life care plan (and died). Results: Sixty-one patients met the audit criteria: the commonest problem was shortness of breath (57.5%), which was generally controlled with conservative doses of morphine (10–20 mg/24 h via a syringe pump). Cough and audible respiratory secretions were relatively uncommon. The second most common problem was agitation/delirium (55.5%), which was generally controlled with standard pharmacological interventions. The cumulative number of patients with shortness of breath, agitation and audible respiratory secretions increased over the last 72 h of life, but most patients were symptom controlled at the point of death. Conclusion: Patients dying of COVID-19 experience similar end-of-life problems to other groups of patients. Moreover, they generally respond to standard interventions for these end-of-life problems.

Background: Delirium is a common severe neuropsychiatric condition secondary to physical illness, which predominantly affects older adults in hospital. Prior to this study, the UK point prevalence of delirium was unknown. We set out to ascertain the point prevalence of delirium across UK hospitals and how this relates to adverse outcomes.Methods: We conducted a prospective observational study across 45 UK acute care hospitals. Older adults aged 65 years and older were screened and assessed for evidence of delirium on World Delirium Awareness Day (14th March 2018). We included patients admitted within the previous 48 h, excluding critical care admissions.Results: The point prevalence of Diagnostic and Statistical Manual on Mental Disorders, Fifth Edition (DSM-5) delirium diagnosis was 14.7% (222/1507). Delirium presence was associated with higher Clinical Frailty Scale (CFS): CFS 4-6 (frail) (OR 4.80, CI 2.63-8.74), 7-9 (very frail) (OR 9.33, CI 4.79-18.17), compared to 1-3 (fit). However, higher CFS was associated with reduced delirium recognition (7-9 compared to 1-3; OR 0.16, CI 0.04-0.77). In multivariable analyses, delirium was associated with increased length of stay (+ 3.45 days, CI 1.75-5.07) and increased mortality (OR 2.43, CI 1.44-4.09) at 1 month. Screening for delirium was associated with an increased chance of recognition (OR 5.47, CI 2.67-11.21).Conclusions: Delirium is prevalent in older adults in UK hospitals but remains under-recognised. Frailty is strongly associated with the development of delirium, but delirium is less likely to be recognised in frail patients. The presence of delirium is associated with increased mortality and length of stay at one month. A national programme to increase screening has the potential to improve recognition.

The article discusses the Scottish Intercollegiate Guidelines Network (SIGN) for risk reduction and management of delirium.

Effective analgesia and sedation in the paediatric intensive care unit (PICU) encompasses the provision of physical comfort and caring for the psychological well-being of critically ill children. In the UK the most commonly used sedative and analgesic agents for critically ill children are midazolam and either morphine or fentanyl. Consensus clinical practice guidelines for the provision of sedation and analgesia in critically ill children were published in 2006 by the UK Paediatric Intensive Care Society, and an ESPNIC position statement on clinical recommendations for pain, sedation, withdrawal and delirium assessment in critically ill infants and children was published in 2016: Despite this, considerable variation in practice persists. Pain experienced early in life may result in long-term changes in neurosensory function and there are also concerns that sedative and analgesic agents may themselves be associated with developmental neurotoxicity, particularly amongst neonates, and adverse psychological outcomes in survivors of critical care. Validated tools for assessment of withdrawal syndrome and delirium are available and this article will briefly discuss these and how to use them in clinical practice. The most important single factor in reducing avoidable psychological morbidity in survivors of PICU is to minimize the administered doses of sedative and analgesic agents. [ABSTRACT FROM AUTHOR]

• Cognitive decline (such as mild cognitive impairment and dementia) is a highly disabling mental disorder affecting 7%–25% of individuals worldwide. • Accumulating evidence supportes the associations between lower serum 25-hydroxyvitamin D (25(OH)D) concentration and dementia, mild cognitive impairment, and delirium. However, the association between 25(OH)D levels and the three diseases in the general population remains unclear. • The present study found that a lower serum 25(OH)D concentration was significantly associated with a higher risk of e dementia (including Alzheimer's disease and vascular dementia), mild cognitive impairment, and delirium. This study aimed to investigate the association between serum 25-hydroxyvitamin D (25(OH)D) levels and dementia, mild cognitive impairment (MCI), and delirium. Participants from the United Kingdom (UK) Biobank with complete information on serum 25(OH)D concentrations were enrolled. Dementia, MCI and delirium were defined using the UK Biobank algorithm. 443,427 participants with a mean (standard deviation) age of 56.8 (8.0) years were included in this study. Based on Cox regression models, serum 25(OH)D concentrations were inversely associated with the risk of dementia, MCI, and delirium in a dose-dependent manner after adjusting for demographics (P-trend <0.001). In comparison with 25(OH)D levels less than 32.4 nmol/L, participants with the highest 25(OH)D levels (i.e., >64.4 nmol/L) had the lowest risk of dementia (hazards ratio [HR]: 0.58, 95% confidence interval [CI] 0.49–0.69, P<0.001), MCI (HR: 0.55, 95% CI 0.37–0.84, P=0.005), and delirium (HR: 0.63, 95% CI 0.51–0.79, P<0.001). These results were consistent with the sensitivity analysis, in which participants with events occurring within the first two years of follow-up were excluded. This study found that a lower serum 25(OH)D concentration was significantly associated with a higher risk of dementia (including Alzheimer's disease and vascular dementia), MCI, and delirium.

Delirium is associated with significant adverse outcomes, including prolonged length of hospital stay, increased dependency and increased mortality but there is a paucity of data pertaining to the management of delirium superimposed on dementia (DSD) in dementia specialist services. Here, the authors discuss their results from measuring the current practice in the management of DSD in a UK dementia specialist unit and an older adult community crisis and home treatment team service and the subsequent action plan formulated to improve patient care.

Background Pain and delirium are common in people with dementia admitted to hospitals. These are often under-diagnosed and under-treated. Pain is implicated as a cause of delirium but this association has not been investigated in this setting. Objective To investigate the relationship between pain and delirium in people with dementia, on admission and throughout a hospital admission. Design Exploratory secondary analysis of observational prospective longitudinal cohort data. Setting Two acute hospitals in the UK. Methodology Two-hundred and thirty participants aged ≥70 years were assessed for dementia severity, delirium ((Confusion Assessment Method (CAM), pain (Pain Assessment in Advanced Dementia (PAINAD)) scale and prescription of analgesics. Logistic and linear regressions explored the relationship between pain and delirium using cross-sectional data. Results Pain at rest developed in 49%, and pain during activity for 26% of participants during their inpatient stay. Incident delirium developed in 15%, of participants, and 42% remained delirious for at least two assessments. Of the 35% of participants who were delirious and unable to self-report pain, 33% of these participants experienced pain at rest, and 56 experienced pain during activity. The odds of being delirious were 3.26 times higher in participants experiencing pain at rest (95% Confidence Interval 1.03–10.25, P = 0.044). Conclusion An association between pain at rest and delirium was found, suggesting pain may be a risk factor for delirium. Since pain and delirium were found to persist and develop during an inpatient stay, regular pain and delirium assessments are required to manage pain and delirium effectively. [ABSTRACT FROM AUTHOR]

Summary: What is known and objective: Drugs with anticholinergic properties increase the risk of falls, delirium, chronic cognitive impairment, and mortality and counteract procholinergic medications used in the treatment of dementia. Medication review and optimisation to reduce anticholinergic burden in patients at risk is recommended by specialist bodies. Little is known how effective this review is in patients who present acutely and how often drugs with anticholinergic properties are used temporarily during an admission. The aim of the study was to describe the changes in the anticholinergic cognitive burden (ACB) in patients admitted to hospital with a diagnosis of delirium, chronic cognitive impairment or falls and to look at the temporary use of anticholinergic medications during hospital stay. Methods: This is a multi‐centre observational study that was conducted in seven different hospitals in the UK, Finland, The Netherlands and Italy. Results and discussion: 21.1% of patients had their ACB score reduced by a mean of 1.7%, 19.7% had their ACB increased by a mean of 1.6%, 22.8% of DAP naïve patients were discharged on anticholinergic medications. There was no change in the ACB scores in 59.2% of patients. 54.1% of patients on procholinergics were taking anticholinergics. Out of the 98 medications on the ACB scale, only 56 were seen. Medications with a low individual burden were accounting for 64.9% of the total burden. Anticholinergic drugs were used temporarily during the admission in 21.9% of all patients. A higher number of DAPs used temporarily during admission was associated with a higher risk of ACB score increase on discharge (OR = 1.82, 95% CI for OR: 1.36‐2.45, P < .001). What is new and conclusion: There was no reduction in anticholinergic cognitive burden during the acute admissions. This was the same for all diagnostic subgroups. The anticholinergic load was predominantly caused by medications with a low individual burden. More than 1 in 5 patients not taking anticholinergics on admission were discharged on them and similar numbers saw temporary use of these medications during their admission. More than half of patients on cholinesterase‐inhibitors were taking anticholinergics at the same time on admission, potentially directly counteracting their effects. [ABSTRACT FROM AUTHOR]

Aim: The determinants of cognitive impairment and delirium during acute illness are poorly understood, despite being common among older people. Anemia is common in older people, and there is ongoing debate regarding the association between anemia, cognitive impairment and delirium, primarily in non‐surgical patients. Methods: Using data from the Older Persons Surgical Outcomes Collaboration 2013 and 2014 audit cycles, we examined the association between anemia and cognitive outcomes in patients aged ≥65 years admitted to five UK acute surgical units. On admission, the Confusion Assessment Method was carried out to detect delirium. Cognition was assessed using the Montreal Cognitive Assessment, and two levels of impairment were defined as Montreal Cognitive Assessment <26 and <20. Logistic regression models were constructed to examine these associations in all participants, and individuals aged ≥75 years only. Results: A total of 653 patients, with a median age of 76.5 years (interquartile range 73.0–80.0 years) and 53% women, were included. Statistically significant associations were found between anemia and age; polypharmacy; hyperglycemia; and hypoalbuminemia. There was no association between anemia and cognitive impairment or delirium. The adjusted odds ratios of cognitive impairment were 0.95 (95% CI 0.56–1.61) and 1.00 (95% CI 0.61–1.64) for the Montreal Cognitive Assessment <26 and <20, respectively. The adjusted odds ratio of delirium was 1.00 (95% CI 0.48–2.10) in patients with anemia compared with those without. Similar results were observed for the ≥75 years age group. Conclusions: There was no association between anemia and cognitive outcomes among older people in this acute surgical setting. Considering the retrospective nature of the study and possible lack of power, findings should be taken with caution. Geriatr Gerontol Int 2018; 18: 1025–1030. [ABSTRACT FROM AUTHOR]

Aims: The aim of this study was to examine perceived barriers to assessment of delirium for critical care nurses, and the impact of education on their knowledge and practice. Background: Delirium is a significant problem in critical care, leading to increased morbidity and mortality. Many authors have found variations in assessment by critical care nurses, but there has been limited analysis of the reasons for this. Education on the topic improves knowledge and practice, but the best approach has not been examined. Design: A questionnaire survey design. Methods: A self-reported questionnaire was distributed to critical care nurses (n=31) at a district general hospital. Data were analysed with descriptive statistics. Results: Knowledge and practice were variable, but correlation was seen between nursing band and years of experience with better scores. Any type of education led to significantly improved scores. Several barriers to assessment were found, with the most common being lack of knowledge and difficulty in assessing intubated patients. Conclusion: It is essential to improve practice in delirium assessment and management. Education is vital to improve the knowledge and practice of critical care nurses regarding delirium.

Background: recognition of prevalent delirium and prediction of incident delirium may be difficult at first assessment. We therefore aimed to validate a pragmatic delirium susceptibility (for any, prevalent and incident delirium) score for use in front-line clinical practice in a consecutive cohort of older acute medicine patients. Methods: consecutive patients aged ≥65 years over two 8-week periods (2010-12) were screened prospectively for delirium using the Confusion Assessment Method (CAM), and delirium was diagnosed using the DSM IV criteria. The delirium susceptibility score was the sum of weighted risk factors derived using pooled data from UK-NICE guidelines: age >80 = 2, cognitive impairment (cognitive score below cut-off/dementia) = 2, severe illness (systemic inflammatory response syndrome) = 1, infection = 1, visual impairment = 1. Score reliability was determined by the area under the receiver operating curve (AUC). Results: among 308 consecutive patients aged ≥65 years (mean age/SD = 81/8 years, 164 (54%) female), AUC was 0.78 (95% CI 0.71-0.84) for any delirium; 0.71 (0.64-0.79), for prevalent delirium; 0.81 (0.70-0.92), for incident delirium; odds ratios (ORs) for risk score 5-7 versus <2 were 17.9 (5.4-60.0), P < 0.0001 for any delirium, 8.1 (2.2-29.7), P = 0.002 for prevalent delirium, and 25.0 (3.0-208.9) P = 0.003 for incident delirium, with corresponding relative risks of 5.4, 4.7 and 13. Higher risk scores were associated with frailty markers, increased care needs and poor outcomes. Conclusions: the externally derived delirium susceptibility score reliably identified prevalent and incident delirium using clinical data routinely available at initial patient assessment and might therefore aid recognition of vulnerability in acute medical admissions early in the acute care pathway.

The article focuses on perioperative management of patients with dementia. It mentions assessment of pain in the patient with dementia that may be complicated by communication difficulties related to dementia or visual and hearing impairments. It highlights efforts to reduce incidence of postoperative delirium that includes avoiding benzodiazepines and anticholinergic drugs, and titrating the dose of volatile and intravenous anaesthetic agents.

Introduction: in the United Kingdom dementia is generally diagnosed by mental health services. General hospitals are managed by separate healthcare trusts and the handover of clinical information between organisations is potentially unreliable. Around 40% of older people admitted to hospital have dementia. This group have a high prevalence of psychological symptoms and delirium. If the dementia diagnosis or symptoms are not recognised, patients may suffer unnecessarily with resulting negative outcomes. Methods: to understand areas of unmet need we have described the prevalence of dementia in over 75 year olds admitted to a general hospital, the accuracy of diagnostic recording, and the prevalence of recorded psychological symptoms and delirium. To achieve this we conducted a retrospective review of 116 patients admitted to hospital with known dementia. Psychiatric and medical notes were reviewed, identifying the accuracy dementia diagnosis recording by the hospital and all episodes of documented psychological symptoms and delirium. Results: the prevalence of documented dementia in the population was estimated at 15%; 74% of dementia diagnoses were recorded in the medical notes; 10% had documented psychological symptoms (depression 4%, anxiety 3%, hallucinations 3%, delusions 4%); and 11% had documented delirium. There were no associations between the specialty providing care and the recognition of dementia or the reporting of symptoms. Discussion: this work suggests an under reporting of dementia and symptoms associated with it in the general hospital. Improving this requires closer collaboration between metal health and hospital healthcare services and training for staff on how to access diagnostic information and recognise common psychological symptoms.

The article offers insights for emergency nurses on recognizing delirium and effectively managing it. Topics covered include the three delirium types of hyperactive, hypoactive, and a mix of both, and their symptoms, such common risk factors as dementia, aged over 65, and frailty, and such obvious causes as pain, infection, and constipation. Also noted are patient approaches by emergency nurses like avoiding unnecessary moves, actively treating conditions, and considering the environment.

Objectives: To identify risk factors of postoperative delirium among hip fracture patients with normal preoperative cognition, and examine associations with returning home or recovery of mobility., Design: Prospective cohort study., Setting and Participants: We used the National Hip Fracture Database (NHFD) to identify patients presenting with hip fracture in England (2018-2019), but excluded those with abnormal cognition [abbreviated mental test score (AMTS) < 8] on presentation., Methods: We examined the results of routine delirium screening performed using the 4 A's Test (4AT), to assess alertness, attention, acute change, and orientation in a 4-item mental test. Associations between 4AT score and return home or to outdoor mobility at 120 days were estimated, and risk factors identified for abnormal 4AT scores: (1) 4AT ≥4 suggesting delirium and (2) 4AT = 1-3 being an intermediate score not excluding delirium., Results: Overall, 63,502 patients (63%) had a preoperative AMTS ≥8, in whom a postoperative 4AT score ≥4 suggestive of delirium was seen in 4454 (7%). These patients were less likely to return home [odds ratio (OR), 0.46; 95% CI, 0.38-0.55] or regain outdoor mobility (OR, 0.63; 95% CI, 0.53-0.75) by 120 days. Multiple factors including any deficit in preoperative AMTS and malnutrition were associated with higher risk of 4AT ≥4, while use of preoperative nerve blocks was associated with lower risk (OR, 0.88; 95% CI, 0.81-0.95). Poorer outcomes were also seen in 12,042 (19%) patients with 4AT = 1-3; additional risk factors associated with this score included socioeconomic deprivation and surgical procedure types that were not compliant with National Institute of Health and Care Excellence guidance., Conclusion and Implications: Delirium after hip fracture surgery significantly reduces the likelihood of returning home or to outdoor mobility. Our findings underline the importance of measures to prevent postoperative delirium, and aid the identification of high-risk patients for whom delirium prevention might potentially improve outcomes., (Copyright © 2023 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Background and objectives: delirium is a distressing but potentially preventable condition common in older people in long-term care. It is associated with increased morbidity, mortality, functional decline, hospitalization and significant healthcare costs. Multicomponent interventions, addressing delirium risk factors, have been shown to reduce delirium by one-third in hospitals. It is not known whether this approach is also effective in long-term care. In previous work, we designed a bespoke delirium prevention intervention, called 'Stop Delirium!' In preparation for a definitive trial of Stop Delirium, we sought to address key aspects of trial design for the particular circumstances of care homes. Design: a cluster randomized feasibility study with an embedded process evaluation. Setting and participants: residents of 14 care homes for older people in one metropolitan district in the UK. Intervention: Stop Delirium!: a 16-month-enhanced educational package to support care home staff to address key delirium risk factors. Control homes received usual care. Measurements: we collected data to determine the following: recruitment and attrition; delirium rates and variability between homes; feasibility of measuring delirium, resource use, quality of life, hospital admissions and falls; and intervention implementation and adherence. Results: two-thirds (215) of eligible care home residents were recruited. One-month delirium prevalence was 4.0% in intervention and 7.1% in control homes. Proposed outcome measurements were feasible, although our approach appeared to underestimate delirium. Health economic evaluation was feasible using routinely collected data. Conclusion: a definitive trial of delirium prevention in long-term care is needed but will require some further design modifications and pilot work. [ABSTRACT FROM AUTHOR]

Background: delirium is under-recognised in comparison to other common and serious acute disorders. A 2006 survey of UK junior doctors (not undertaking specialist training) identified poor knowledge of the diagnostic criteria and treatment of delirium. We hypothesised that increased prominence accorded to delirium in the form of national initiatives and guidelines may have had an impact on understanding among junior doctors. Objective: we repeated a multi-centre survey of knowledge of and attitudes to delirium in junior doctors (not undertaking specialist training) assessing unselected acute medical presentations (the 'medical take'). Design: questionnaire-based survey in 48 acute hospitals in UK and Ireland. Methods: we used questionnaires designed to test understanding of delirium, including prevalence, knowledge of the DSM-IV diagnostic criteria, use of specific screening tools, association with adverse outcomes and pharmacological management. Results: one thousand two hundred and fifteen trainee physicians participated. Compared with the 2006 cohort, improvements were seen in 9 of 17 knowledge-based questions and overall score improved in the 2013 cohort. Nonetheless, significant deficits in knowledge, particularly for the diagnostic criteria for delirium, remained. Conclusions: despite improvements in some aspects of delirium knowledge, the diagnostic criteria for delirium remain poorly understood. Challenges remain in ensuring adequate training for junior doctors in delirium. [ABSTRACT FROM AUTHOR]

Background: delirium and dementia are common in the general hospital, being present in nearly 50% of older unselected admissions to hospital. Cognitive impairment is a risk factor for delirium, but the prevalence of previously undiagnosed cognitive impairment (dementia or mild cognitive impairment) in patients with delirium is unknown. Methods: we performed a prospective cohort study of people over 70 years admitted to hospital with delirium to establish the prevalence of previously unrecognised prior cognitive impairment. Delirium was diagnosed at baseline using the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Mild cognitive impairment and dementia were diagnosed 3 months following recruitment in survivors using the International Working Group on Mild Cognitive Impairment criteria and DSM- IV criteria, respectively. Results: delirium was identified in 17.9% of older patients, and 82 participants with delirium were assessed at 3 months: 5 (6%) had persistent delirium, 14 (17%) had mild cognitive impairment and 47 (57%) had dementia. In 17 participants with prior dementia and 14 with prior mild cognitive impairment, the diagnosis had been unrecognised, amounting to 31/82 (38%) of all patients with delirium having some form of previously undiagnosed cognitive impairment. Conclusion: given that over 1/3 of older patients with delirium were found to have a previously undiagnosed cognitive impairment, the development and evaluation of services to follow-up and manage patients with delirium are warranted.

Objectives To examine whether delirium in individuals with hip fracture is associated with high C-reactive protein ( CRP), interleukin-6 ( IL-6), and soluble IL-6 receptor ( sIL-6R) levels in the cerebrospinal fluid ( CSF). Design Prospective cohort study. Setting Two university hospitals in Oslo, Norway, and Edinburgh, United Kingdom. Participants Individuals admitted with acute hip fracture (N = 151). Measurements Participants were assessed for delirium pre- and postoperatively using the Confusion Assessment Method. Prefracture cognitive impairment was detected using the Informant Questionnaire on Cognitive Decline in the Elderly ( IQCODE). Serum was collected preoperatively and CSF just before the onset of spinal anesthesia. Cytokine levels in serum and CSF samples were determined using an enzyme-linked immunosorbent assay. Student t-tests or Mann-Whitney U-tests were used for between-group comparisons. Spearman rho was used for correlations. Results Sixty participants had prior cognitive impairment ( IQCODE score ≥3.44). Delirium was diagnosed in 46 participants (77%) with prior cognitive impairment and 25 (29%) without. In participants without prior cognitive impairment, CSF CRP levels were higher in participants with delirium (median 0.05 μg/mL, interquartile range ( IQR) 0.02-0.12 μg/mL) than in those without delirium (median 0.01 μg/mL, IQR 0.00-0.06 μg/mL) ( P = .01); there were no differences in participants with prior cognitive impairment. In secondary analyses, in participants with prior cognitive impairment, the concentration of CSF sIL-6R was higher in those participants who developed delirium than in the other subgroups, but this difference was not statistically significant. Serum levels of CRP, IL-6, and sIL-6R were not different according to delirium in participants with or without prefracture cognitive impairment. Conclusion High CSF levels of CRP and sIL-6R may be associated with delirium. Different pathophysiological mechanisms may operate in different subgroups, notably in relation to the presence of prior cognitive impairment. [ABSTRACT FROM AUTHOR]

Patients with dementia and delirium in acute hospitals can exhibit verbal agitation, but there is no research on rate of occurrence or how ward staff manage such behaviour. This service evaluation aimed to measure rate of occurrence of verbal agitation in confused older inpatients and understand the management strategies used by staff. An agitation inventory was completed daily by the nursing team for all verbally agitated patients on eight older person wards over two weeks. Six semi-structured interviews were conducted with staff and three hours of non-participant observations were undertaken. A mean 6% (13/223) of patients were verbally agitated each day. Management strategies included trial and error, distraction and engagement, reassurance, communication and familiarity. Staff did not adopt a systematic approach to care planning due to lack of training and support on the ward, as well as scarce resources in terms of staff, space and activities. Research is needed to develop and evaluate interventions that support staff to care for these patients. [ABSTRACT FROM AUTHOR]

Dementia is a common condition in the UK with around 25% of patients in acute hospitals having dementia. In the UK, there is national guidance on the assessment of cognitive impairment in acute hospitals. This article is a qualitative study of junior doctors' experiences as part of a dementia and delirium team involved in changing the care of patients with dementia in a hospital in the UK. It draws on data from a focus group and follow-up questionnaire in two hospital trusts. We examine what drives doctors to become involved in such projects and the effects of this experience upon them. We suggest a typology for getting junior doctors involved in projects generating change when working with patients with dementia. Being more actively involved in caring for and developing services for patients with dementia may represent the crossing of an educational threshold for these junior doctors. [ABSTRACT FROM AUTHOR]
