Face and content validity of a mobile delirium screening tool adapted for use in the medical setting (eDIS-MED): Welcome to the machine.

OBJECTIVES: Following a user-centred redesign and refinement process of an electronic delirium screening tool (eDIS-MED), further accuracy assessment was performed prior to anticipated testing in the clinical setting. METHODS: Content validity of each of the existing questions was evaluated by an expert group in the domains of clarity, relevance and importance. Questions with a Content Validity Index (CVI) <0.80 were reviewed by the development group for potential revision. Items with CVI <0.70 were discarded. Next, face validity of the entirety of the tests was conducted and readability measured. RESULTS: A panel of five clinical experts evaluated the test battery comprising eDIS-MED. The content validity process endorsed 61 items. The overall scale CVI was 0.92. Eighty-eight per cent of the responses with regard to question relevancy, usefulness and appropriateness were positive. The questions were deemed fifth grade level and very easy to read. CONCLUSIONS: A revised electronic screening tool was shown to be accurate according to an expert group. A clinical validation study is planned.

A narrative review of the development and performance characteristics of electronic delirium-screening tools.

BACKGROUND: Electronic delirium-screening tools are an emergent area of research. OBJECTIVE: The objective of this study was to summarise the development and performance characteristics of electronic screening tools in delirium. METHODS: Searches were conducted in Pubmed, Embase, and CINAHL Complete databases to identify electronic delirium-screening tools. RESULTS: Five electronic delirium-screening tools were identified and reviewed. Two were designed for and tested within a medical setting, and three were applied to intensive care. Adaptive design features, such as skip function to reduce test burden, were variably integrated into instrument design. All tools were shown to have acceptable psychometric properties, but validation studies were largely incomplete. CONCLUSIONS: Electronic delirium-screening tools are an exciting area of development and may offer hope for improved uptake of delirium screening.

Reduced cortical cholinergic innervation measured using [18F]-FEOBV PET imaging correlates with cognitive decline in mild cognitive impairment.

Dysfunction of the cholinergic basal forebrain (BF) neurotransmitter system, including cholinergic axon denervation of the cortex, plays an important role in cognitive decline and dementia. A validated method to directly quantify cortical cholinergic terminal integrity enables exploration of the involvement of this system in diverse cognitive profiles associated with dementia, particularly at a prodromal stage. In this study, we used the radiotracer [18F]-fluoroethoxybenzovesamicol (FEOBV) as a direct measure of cholinergic terminal integrity and investigated its value for the assessment of cholinergic denervation in the cortex and associated cognitive deficits. Eighteen participants (8 with mild cognitive impairment (MCI) and 10 cognitively unimpaired controls) underwent neuropsychological assessment and brain imaging using FEOBV and [18F]-florbetaben for amyloid-ß imaging. The MCI group showed a significant global reduction of FEOBV retention in the cortex and in the parietal and occipital cortices specifically compared to the control group. The global cortical FEOBV retention of all participants positively correlated with the BF, hippocampus and grey matter volumes, but no association was found between the global FEOBV retention and amyloid-ß status. Topographic profiles from voxel-wise analysis of FEOBV images revealed significant positive correlations with the cognitive domains associated with the underlying cortical areas. Overlapping profiles of decreased FEOBV were identified in correlation with impairment in executive function, attention and language, which covered the anterior cingulate gyrus, olfactory cortex, calcarine cortex, middle temporal gyrus and caudate nucleus. However, the absence of cortical atrophy in these areas suggested that reduced cholinergic terminal integrity in the cortex is an important factor underlying the observed cognitive decline in early dementia. Our results provide support for the utility and validity of FEOBV PET for quantitative assessment of region-specific cholinergic terminal integrity that could potentially be used for early detection of cholinergic dysfunction in dementia following further validation in larger cohorts.

A delicate balance: Psychotropic polypharmacy and anti-cholinergic use are correlated with fall incidence in Australian inpatients with dementia.

BACKGROUND: Persons with dementia commonly experience a range of behavioural and psychological symptoms, including agitation, aggression, perceptual disturbances, and depression. While psychotropic medications are regularly prescribed to mitigate these symptoms, these agents also carry a broad adverse effect profile. This study aimed to characterize psychotropic medication use in patients with dementia, as well as identify prescribing factors associated with falls in this cohort. METHODS: This retrospective study collected longitudinal demographic and medication data from all patients admitted to a neuro-cognitive unit at an Australian metropolitan hospital over a 2-year period. Psychotropic polypharmacy and psychotropic agent use per patient-fortnight were investigated for their association with inpatient falls. RESULTS: All patients (n = 147) were prescribed at least one psychotropic medication, with 96% receiving anti-psychotic medications and 90% receiving benzodiazepines. Patient fall rate was significantly associated with anticholinergic drug use (Incidence rate ratio: 2.2; P < .001), as well as concomitant use of ≥5 daily psychotropic agents (Incidence rate ratio: 3.1; P = .001). CONCLUSIONS: Patients with dementia are routinely prescribed a wide variety of psychotropic medications. Use of anticholinergic drugs and psychotropic polypharmacy are correlated with fall incidence in persons with dementia.

Screening for delirium in the intensive care unit using eDIS-ICU - A purpose-designed app: A pilot study.

INTRODUCTION: Delirium, a common complication of an intensive care unit (ICU) admission, is inconsistently diagnosed by clinicians. Current screening tools require specialist expertise and/or training. Some are time-consuming to administer, and reliability in routine clinical practice is questionable. An innovative app designed to enable efficient and sensitive screening for delirium without specialist training (eDIS-ICU) has recently been described. This pilot study compared the eDIS-ICU against the reference standard expert assessment using DSM-V (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) criteria and the Confusion Assessment Method for the ICU (CAM-ICU). METHODS: In this prospective, single-centre pilot study, a convenience sample of 29 ICU patients were recruited at a tertiary referral hospital between November 2018 and August 2019. After obtaining written consent, demographic and clinical data were collected, and the patients were screened for delirium using eDIS-ICU and CAM-ICU by two clinician researchers in random order. The patients were also assessed for presence of delirium independently by an expert clinician using a structured interview to diagnose as per DSM-V criteria. The results of screening and diagnosis were tabulated to allow comparison of screening tools against diagnosis; sensitivity and specificity of the tools were calculated. RESULTS: Seven participants were diagnosed with delirium as per DSM-V criteria. The eDIS-ICU tool correctly identified six of these participants compared with two identified by CAM-ICU. The sensitivity of the eDIS-ICU tool was 86% (95% confidence interval [CI] = 81.5-100.0) compared with 29% (95% CI = 5.1-69.7) for CAM-ICU (p < 0.05), and the specificity was 73% (95% CI = 81.5-100.0) versus 96% (95% CI = 75.1-99.8), respectively. CONCLUSION: The simple and novel eDIS-ICU delirium screening tool was noninferior to the CAM-ICU in detecting delirium as per DSM-V criteria. A definitive validation study is warranted.

Development and validation of an aetiology in delirium diagnostic support tool.

BACKGROUND: recognition of the multifactorial causes of delirium represents a clinical challenge. OBJECTIVES: to develop and show proof of principle of a diagnostic support tool (DST) for identification of causes of delirium. METHODS: stage 1-development of the aetiology in delirium-diagnostic support tool (AiD-DST); stage 2-validation of the AiD-DST against reference standard diagnosis, based on clinical assessment from two independent consultant geriatricians. RESULTS: a series of eight steps AiD-DST were formulated by an expert group to identify possible causes of delirium. Forty inpatients admitted to a general medical unit with a consultant physician/geriatrician diagnosis of delirium were recruited, consented and reviewed against the AiD-DST. Mean age was 85.1 (standard deviation 7.9) years and 26 (65%) of participants were female. Participants had multiple chronic co-morbidities [median Charlson Comorbidity Index 7; interquartile range (IQR 6-9)] and median number of medications was 8 (IQR 6-11.75). Median number of causes of delirium detected on AiD-DST was 3 (IQR 3-4) versus 5 (IQR 3-6) using the reference standard diagnosis, with sensitivity of 88.8% (95% confidence interval, 81.6-93.9%) and specificity of 71.8% (63-79.5%). CONCLUSIONS: the aetiology in delirium DST shows promise in the identification of cause(s) in delirium.

Consciousness and the rabbit holes of delirium.

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

Delirium Management: Anything's Possible.

Le délirium est un problème de santé majeur aux conséquences potentiellement graves. Malheureusement, la prise en charge de ce trouble est souvent sous-optimale. Nous considérons que les lacunes dans les soins offerts aux patients avec délirium sont liées aux particularités de cette condition, qui affecte la perception du « soi ¼ de la personne qui en souffre. Cette atteinte entraîne un comportement hors de contrôle chez la personne avec délirium et l'expose à une déshumanisation mécaniste. Une solution consisterait à favoriser une vision élargie du « soi ¼, inspirée de la philosophie et des sciences cognitives récentes, afin d'aider les cliniciens dans la compréhension du comportement pathologique en tant que manifestation de la perturbation de la pensée. Une approche centrée sur l'éthique des soins, intégrant un nouveau cadre pour la relation patient-soignant, est proposée. Considérées dans leur ensemble, les propositions novatrices émises pourraient faciliter l'élaboration d'un cadre de pratiques et de relations plus attentionnées et plus efficaces pour le traitement du délirium.Delirium is a major health care problem with potentially serious consequences. Sub-optimal management is an unfortunate but pervasive hallmark of the disorder. We argue that lapses in the care of delirious patients are related to the peculiarities of delirium as a disorder that affects the "self" of the sufferer. Therefore, corruption of self renders behaviour outside the control of the delirious individual and places the person at risk of mechanistic dehumanisation. A proposed solution is to foster an expanded view of the self, taken from recent philosophy and cognitive science, which would allow the clinician to understand pathological behaviour as indicative of disruption to thought. An ethics of care approach that reframes the patient/carer relationship is proposed. These unique propositions could, together, facilitate the development of a framework of more caring and effective practices and relationships for delirium treatment.

Outcomes for patients with delirium receiving hospital-in-the-home treatment: An Australian perspective.

OBJECTIVE: To evaluate the safety (mortality and readmissions) and efficiency (length of stay) of the hospital-in-the-home delirium pathway (THDP) compared with hospital-based care. METHODS: Patients admitted to THDP were compared against an age-matched cohort of patients with delirium managed entirely in hospital. Outcome data were obtained through retrospective chart review, and hospital coding was used to identify controls. RESULTS: Ninety-six patients were included in this study, of which 46 were managed on THDP. There was a significant frailty and co-morbidity burden with no differences in the demographic profile between groups. Inpatient length of stay was shorter on THDP (THDP mean 8 days, control 11 days; P = .02). One-month mortality was 13% in THDP compared with 24% in the control group (P = .2). One-month readmission was 30% in THDP and 18% in the control group (P = .23). CONCLUSION: The hospital-in-the-home delirium pathway is a promising alternative to in-hospital delirium care for selected patients.

e-Screening revolution: A novel approach to developing a delirium screening tool in the intensive care unit.

OBJECTIVES: Delirium is common in the intensive care unit (ICU), often affecting older patients. A bedside electronic tool has the potential to revolutionise delirium screening. Our group describe a novel approach to the design and development of delirium screening questions for the express purpose of use within an electronic device. Preliminary results are presented. METHODS: Our group designed a series of tests which targeted the clinical criteria for delirium according to Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5) criteria against predefined requirements, including applicability to older patients. RESULTS: Candidate questions, including tests of attention and awareness, were devised and then refined by an expert multidisciplinary group, including geriatricians. A scoring scheme was constructed, with testing to failure an indicator of delirium. The device was tested in healthy controls, aged 20-80 years, who were recorded as being without delirium. CONCLUSION: e-Screening for delirium requires a novel approach to instrument design but may revolutionise recognition of delirium in ICU.

Delirium care: Real-world solutions to real-world problems.

OBJECTIVES: Implementation research into delirium care is lacking. Exploiting known practice barriers to understand what management strategies work best in delirium is a means of prioritising care interventions. A consensus approach to determining priority interventions in delirium was derived and related to reference standards in health-care practice. METHODS: A workshop of 20 experts was held at the Australasian Delirium Association conference 2016. Structured small group work, iterative ranking and a 21-member check were undertaken to (i) explore research barriers in delirium care; (ii) explore how barriers related to individual items of multicomponent interventions; and (iii) rank multicomponent interventions in relation to each statement within the newly released Australian Commission on Safety and Quality in Health Care delirium standard. RESULTS: Top-ranking interventions included the following: education and training, comprehensive geriatric assessment, family partnerships, individualised care and multidisciplinary engagement. CONCLUSION: Delirium experts identified a minimum standard of any care intervention for delirium.

Consciousness, Functional Networks and Delirium Screening.

BACKGROUND: Consciousness, the medium of sentient thought, requires integrity of functional networks and their connectivity. In health, they function as a co-operative but mutually exclusive paradigm of introspection versus external awareness subserved via the Default Mode Network and Task Positive State, respectively. Higher thinking in the conscious state is then segregated according to need. There is research evidence to suggest that functional networks may be impacted in disorders of consciousness and conceptual support for a mechanistic role in delirium. This potentially central aspect of delirium manifestation is relatively unexplored. OBJECTIVE: This article describes the role of disrupted functional networks in delirium. How this relates to current understanding of delirium neurobiology and the ramifications for clinical diagnosis is discussed. METHOD: A review of the role of functional networks, particularly DMN and TPN, has been undertaken with respect to health and delirium. An exploration of how symptoms of delirium may be related to functional network aberrancy has been undertaken. Implications for research and clinical practice in delirium have been presented. RESULTS: In delirium, a disturbance of consciousness, the DMN is pathologically co-activated and functional cortical connectivity is compromised. The clinical correlate is of an experiential singularity where internal and external drivers become indistinguishable, reality and delusion merge and the notion of self is effaced. Our group propose that functional network disruption in conjunction with cortical disconnectivity is central to the mechanism of delirium. Clinical tools may exploit the neurobiology of delirium to improve its diagnosis and an example of such a simple screening instrument (SQeeC) is provided. CONCLUSION: Functional networks are critically disrupted in delirium and may be central to clinical features. A better understanding of the neurobiology of delirium will generate research opportunities with potential for therapeutic gains in detection, diagnosis, and management.

Neurological Injury in Intermediate-Risk Transcatheter Aortic Valve Implantation.

BACKGROUND: The application of transcatheter aortic valve implantation (TAVI) to intermediate-risk patients is a controversial issue. Of concern, neurological injury in this group remains poorly defined. Among high-risk and inoperable patients, subclinical injury is reported on average in 75% undergoing the procedure. Although this attendant risk may be acceptable in higher-risk patients, it may not be so in those of lower risk. METHODS AND RESULTS: Forty patients undergoing TAVI with the Edwards SAPIEN-XT™ prosthesis were prospectively studied. Patients were of intermediate surgical risk, with a mean±standard deviation Society of Thoracic Surgeons score of 5.1±2.5% and a EuroSCORE II of 4.8±2.4%; participant age was 82±7 years. Clinically apparent injury was assessed by serial National Institutes of Health Stroke Scale assessments, Montreal Cognitive Assessments (MoCA), and with the Confusion Assessment Method. These identified 1 (2.5%) minor stroke, 1 (2.5%) episode of postoperative delirium, and 2 patients (5%) with significant postoperative cognitive dysfunction. Subclinical neurological injury was assessed using brain magnetic resonance imaging, including diffusion-weighted imaging (DWI) sequences preprocedure and at 3±1 days postprocedure. This identified 68 new DWI lesions present in 60% of participants, with a median±interquartile range of 1±3 lesions/patient and volumes of infarction of 24±19 µL/lesion and 89±218 µL/patient. DWI lesions were associated with a statistically significant reduction in early cognition (mean ΔMoCA -3.5±1.7) without effect on cognition, quality of life, or functional capacity at 6 months. CONCLUSIONS: Objectively measured subclinical neurological injuries remain a concern in intermediate-risk patients undergoing TAVI and are likely to manifest with early neurocognitive changes.

Describe the incidence of dehydration in older hospitalized patients. 2. Identify risk and management strategies related to dehydration in older hospitalized patients. DISCLOSURE STATEMENT Neither the planners nor the author have any conflicts of interest to disclose. The current exploratory study (a) assessed the prevalence of dehydration in older adults (age ≤60 years) with and without cognitive impairment (CI) admitted to the hospital; and (b) examined associations between dehydration, CI, and frailty. Forty-four patients participated and dehydration was assessed within 24 hours of admission and at Day 4 or discharge (whichever occurred first). Patients' cognitive function and frailty statuses were assessed using validated instruments. Twenty-seven (61%) patients had CI and 61% were frail. Prevalence of dehydration at admission was 29% (n = 12) and 21% (n = 9) [corrected] at study exit, and dehydration status did not differ according to CI or frailty status. However, within the non-CI group, significantly more frail than fit patients were dehydrated at admission (p = 0.03). Findings indicate dehydration is common among older hospitalized patients and that frailty may increase the risk for dehydration in cognitively intact older adults. [Journal of Gerontological Nursing, 42(5), 19-27.].

Frailty and Mobility.

Frailty represents a state of heightened vulnerability. Mobility impairment contributes to the construct of frailty and channels adverse events. While mobility disorder is universal at a high burden of frailty, neither mobility nor balance dysfunction is sufficient to fully define frailty. Frailty represents proximity to complex system failure, with higher-order disturbance, such as mobility and balance disturbance, as a consequence. Impairment of mobility and balance is a common manifestation of illness in the frail individual and is therefore a sensitive marker of acute disease, putatively also in delirium. Clinical measurement of mobility and balance should be prioritized. Consequently, assessment tools, such as the de Morton Mobility Index and the Hierarchical Assessment of Balance and Mobility, are being explored, with the sensitivity of the latter illustrated in the acute hospital setting. Walking with speed and under dual/multi-task conditions better differentiates healthier and frail ambulant adults, providing a basis for screening older adults for pre-emptive interventions. Specific mobility and balance interventions reduce falls risk. However, patients with dementia walk too fast for their level of frailty, creating an ethical dimension to rehabilitation and risk. Overall, there is no need for reduced mobility to reinforce the frailty stereotype; both are potentially modifiable and amenable to intervention strategies.

Screening in delirium: A pilot study of two screening tools, the Simple Query for Easy Evaluation of Consciousness and Simple Question in Delirium.

AIM: Delirium is poorly recognised and inadequately treated in medical settings. This research aimed to determine the psychometric properties of a newly developed tool, SQeeC against another emergent instrument, SQiD, in the screening of delirium. METHODS: The SQeeC was administered to 100 patients and SQiD administered to their informants in the general medical wards of a General Hospital. Data were compared with the reference standard geriatric consultant assessment of delirium. RESULTS: Compared with the reference standard, the SQeeC was found to have a sensitivity of 83% (95% CI 52-98%) and a specificity of 81% (95% CI 72-89%) with a negative predictive value of 97% (95% CI 90-100%) while the SQiD was found to have a sensitivity of 77% (95% CI 56-91%), a specificity of 51% (95% CI 37-64%) and a negative predictive value of 83% (95% CI 66-93%). CONCLUSION: The SQeeC and SQiD are simple and time efficient screening tools with encouraging psychometric properties.

The silent and apparent neurological injury in transcatheter aortic valve implantation study (SANITY): concept, design and rationale.

BACKGROUND: The incidence of clinically apparent stroke in transcatheter aortic valve implantation (TAVI) exceeds that of any other procedure performed by interventional cardiologists and, in the index admission, occurs more than twice as frequently with TAVI than with surgical aortic valve replacement (SAVR). However, this represents only a small component of the vast burden of neurological injury that occurs during TAVI, with recent evidence suggesting that many strokes are clinically silent or only subtly apparent. Additionally, insult may manifest as slight neurocognitive dysfunction rather than overt neurological deficits. Characterisation of the incidence and underlying aetiology of these neurological events may lead to identification of currently unrecognised neuroprotective strategies. METHODS: The Silent and Apparent Neurological Injury in TAVI (SANITY) Study is a prospective, multicentre, observational study comparing the incidence of neurological injury after TAVI versus SAVR. It introduces an intensive, standardised, formal neurologic and neurocognitive disease assessment for all aortic valve recipients, regardless of intervention (SAVR, TAVI), valve-type (bioprosthetic, Edwards SAPIEN-XT) or access route (sternotomy, transfemoral, transapical or transaortic). Comprehensive monitoring of neurological insult will also be recorded to more fully define and compare the neurological burden of the procedures and identify targets for harm minimisation strategies. DISCUSSION: The SANITY study undertakes the most rigorous assessment of neurological injury reported in the literature to date. It attempts to accurately characterise the insult and sustained injury associated with both TAVI and SAVR in an attempt to advance understanding of this complication and associations thus allowing for improved patient selection and procedural modification.

Predicting outcome after hip fracture: using a frailty index to integrate comprehensive geriatric assessment results.

INTRODUCTION: hip fracture is expensive in terms of mortality, hospital length of stay (LOS) and consequences for independence. Poor outcome reflects the vulnerability of patients who typically sustain this injury, but the impact of different comorbidities and impairments is complex to understand. We consider this in a prospective cohort study designed to examine how a patients' frailty index (FI) predicts outcome. METHODOLOGY: consecutive patients with low trauma hip fracture were assessed, excluding only those unfit for surgery. Comprehensive Geriatric Assessment (CGA) findings were used to derive a FI for each patient, which was examined alongside other assessment and outcome data from our National Hip Fracture Database (NHFD) submission for these individuals. RESULTS: we describe 178 patients; mean age 81 years, 73.5% female. The mean FI was 0.34 (SD = 0.16), and logistic regression identified abbreviated mental test score and FI as the strongest predictors of poor outcome. When patients were stratified by FI, 56 (31.5%) were in the low-frailty group (FI ≤0.25), 58 (32.5%) in intermediate (FI >0.25-0.4), and 64 (36%) in the high-FI group (FI >0.4). All the patients in the low-FI group returned to their original residence within a mean of 21.6 days. The mean LOS for the intermediate group was 36.3 days compared with 67.8 days in the high-FI group (P < 0.01) while 30-day mortality was 3.4% for the intermediate group compared with 17.2% for the high-FI group (P < 0.001). CONCLUSIONS: individual CGA findings proved disappointing as outcome predictors, while FI turned out to be a better predictor of mortality, 30-day residence and length of inpatient stay.
