Detection of delirium in older patients-A point prevalence study in surgical and non-surgical hospital wards. Scand J Caring Sci 2024; 38:579-588. [PMID: 38702945 DOI: 10.1111/scs.13270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 02/13/2024] [Accepted: 04/20/2024] [Indexed: 05/06/2024]
Abstract
AIMS AND OBJECTIVES To (i) determine the prevalence of delirium and identify delirium subtypes in surgical and non-surgical patients aged ≥65 years, (ii) determine whether certain precipitating factors affect the prevalence of delirium and (iii) review patients' medical records for description of delirium symptoms and the presence of International Classification of Diseases (ICD-10) coding for delirium in discharge summaries. METHODOLOGICAL DESIGN AND JUSTIFICATIONS Despite being a robust predictor of morbidity and mortality in older adults, delirium might be inadequately recognised and under-reported in patients' medical records and discharge summaries. A point prevalence study (24-h) of patients ≥65 years from surgical and non-surgical wards was therefore conducted in a tertiary university hospital. ETHICAL ISSUES AND APPROVAL The study was approved by the Data Protection Officer at the university hospital (2018/3454). RESEARCH METHODS, INSTRUMENTS AND/OR INTERVENTIONS Patients were assessed for delirium with 4AT and delirium subtypes with the Delirium Motor Subtype Scale. Information about room transfers, need and use of sensory aids and medical equipment was collected onsite. Patients' medical records were reviewed for description of delirium symptoms and of ICD-10 codes. RESULTS Overall, 123 patients were screened (52% female). Delirium was identified in 27% of them. Prevalence was associated with advanced age (≥85 years). The uncharacterised delirium subtype was most common (36%), followed by hypoactive (30%), hyperactive (24%) and mixed (9%). There were significant associations between positive screening tests and the need and use of sensory aids. Delirium symptoms were described in 58% of the patients who tested positive for delirium and the ICD-10 code for delirium was registered in 12% of these patients' discharge summaries. CONCLUSIONS The high prevalence of delirium and limited use of discharge codes highlight the need to improve the identification of delirium in hospital settings and at discharge. Increased awareness and detection of delirium in hospital settings are vital to improve patient care.

Decreasing the incidence of delirium via multi-sensory stimulation in patients receiving mechanical ventilation in the intensive care unit: A protocol for a randomized feasibility study. Contemp Clin Trials Commun 2024; 38:101263. [PMID: 38304570 PMCID: PMC10831177 DOI: 10.1016/j.conctc.2024.101263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 01/09/2024] [Accepted: 01/15/2024] [Indexed: 02/03/2024] Open
Abstract
Introduction Delirium is a common acute brain dysfunction syndrome in patients admitted to intensive care units (ICUs). Family engagement strategies, based on the theory of multi-sensory stimulation to ameliorate sensory deprivation in patients, may be an effective and scalable method to reduce the burden of delirium. Methods /design: This is a assessor-blinded, randomised controlled trial of the feasibility of multi-sensory stimulation (MS) in patients with delirium. A total of 72 mechanically ventilated patients (n = 24 in each group) admitted to the ICU will be randomised to routine non-pharmacological delirium care (control), family multi-sensory stimulation and nurse multi-sensory stimulation groups. All participants except the control group will receive multi-sensory stimulation, including visual, auditory, tactile and kinesthetic stimulation, for 5 days. Our primary aim is to determine the feasibility of the study procedure (recruitment, eligibility, retention and attrition rates, appropriateness of clinical outcome measures), feasibility, acceptability and safety of the intervention (adverse events, satisfaction and other). Our secondary objective is to assess the preliminary efficacy of the MS protocol in reducing the incidence, duration and severity of delirium. Sedation levels and delirium severity will be assessed twice daily. Enrolled participants will be followed in hospital until death, discharge or up to 28 days after treatment. Ethics and dissemination The current study was approved by the Ethics Review Board of Huazhong University of Science and Technology Union Shenzhen Hospital, China (KY-2023-031-01). The results of this study will be presented at scientific conferences and submitted for publication in peer-reviewed journals. Trial registration number ChiCTR2300071457.

Abstract
OBJECTIVE To investigate whether an assessment of delirium severity at diagnosis using the Delirium Observation Screening Scale (DOS scale) predicts adverse outcomes in hospital and on discharge. METHODS A prospective cohort study was conducted on a convenience sample of patients admitted to an acute geriatric ward with delirium over an eight-month period. DOS scale was administered to the patients within 48 h of delirium diagnosis to measure delirium severity. Univariate logistic regression analysis was performed to evaluate the correlation between DOS scale and adverse outcomes. RESULTS Fifty-nine patients were included in the study. There was a moderate correlation between increasing DOS scores and duration of delirium (r = 0.46, p < 0.001), as well as increasing DOS scores and decline in mobility on discharge (r = 0.35, p = 0.007). There was a weak correlation between increasing DOS scores and functional decline as measured by change in Katz Index from admission to discharge (r = -0.27, p = 0.04). No statistically significant correlations were found between DOS scores and in-hospital mortality, inpatient complication rates or discharge to higher level of care. CONCLUSION Delirium severity as measured by DOS scale may be useful in predicting delirium duration and decline in mobility and function on discharge. Further research with larger sample sizes is needed to establish if this finding can be replicated and whether delirium severity predicts additional adverse outcomes. Measuring delirium severity at diagnosis may be useful for communicating prognostic information to family members and setting expectations and treatment goals.

Abstract
AIMS This scoping review aimed to identify and map the available information on the nutrition care process in older adults with delirium to analyse and summarise key concepts, and gaps, including the barriers and enablers to providing nutrition care for this group. DESIGN Scoping review. METHODS This review was conducted in accordance with the JBI methodology for scoping reviews. Published and grey sources in English were considered. DATA SOURCES Databases searched were CINAHL, Medline, Embase, JBI Evidence-based Practice, Scopus, ProQuest and Google. The initial search was conducted from October 2021 to March 2022 and repeated in October 2023. RESULTS The database search identified 1561 articles, 186 underwent full-text review and 17 articles were included. The grey literature search identified eight articles. Malnutrition and delirium were identified as mutually reinforcing, and nutrition strategies were included as part of multicomponent interventions for delirium management. There was no mention of barriers or enablers to nutrition care and minimal descriptive or empirical data available to guide nutrition care processes in this group. CONCLUSION This scoping review revealed a need for further research into nutrition care processes in older patients with delirium, in particular the barriers and enablers, to inform appropriate management strategies in this vulnerable group. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE Providing nutrition care for older patients with delirium is important and further practical guidance could help patients, healthcare staff and families. IMPACT This scoping review yielded instructive data suggesting that delirium is an important risk factor for malnutrition and vice versa, which leads to poor patient and health service outcomes. REPORTING METHOD This scoping review adhered to relevant EQUATOR guidelines and used the Preferred Reporting Items For Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). PATIENT OF PUBLIC CONTRIBUTION No patient or public contribution.

Abstract
BACKGROUND Delirium is common in geriatric inpatients and associated with poor outcomes. Hospitalization is associated with low levels of physical activity. Motor symptoms are common in delirium, but how delirium affects physical activity remains unknown. AIMS To investigate differences in physical activity between geriatric inpatients with and without delirium. METHODS We included acutely admitted patients ≥ 75 years in a prospective observational study at a medical geriatric ward at a Norwegian University Hospital. Delirium was diagnosed according to the DSM-5 criteria. Physical activity was measured by an accelerometer-based device worn on the right thigh. The main outcome was time in upright position (upright time) per 24 h (00.00 to 23.59) on the first day of hospitalization with verified delirium status. Group differences were analysed using t test. RESULTS We included 237 patients, mean age 86.1 years (Standard Deviation (SD) 5.1), and 73 patients (30.8%) had delirium. Mean upright time day 1 for the entire group was 92.2 min (SD 84.3), with 50.9 min (SD 50.7) in the delirium group and 110.6 min (SD 89.7) in the no-delirium group, mean difference 59.7 minutes, 95% Confidence Interval 41.6 to 77.8, p value < 0.001. DISCUSSION Low levels of physical activity in patients with delirium raise the question if immobilization may contribute to poor outcomes in delirium. Future studies should investigate if mobilization interventions could improve outcomes of delirium. CONCLUSIONS In this sample of geriatric inpatients, the group with delirium had lower levels of physical activity than the group without delirium.

Abstract
Objectives Recognition of the cognitive status of patients is important so that care can be tailored accordingly. The objective of this integrative review was to report on the current practices that acute care hospitals use to identify people with cognitive impairment and how information about cognition is managed within the healthcare record as well as the approaches required and recommended by policies. Methods Following Whittemore & Knafl's five-step method, we systematically searched Medline, CINAHL, and Scopus databases and various grey literature sources. Articles relevant to the programs that have been implemented in acute care hospitals regarding the identification of cognitive impairment and management of cognition information were included. The Mixed Methods Appraisal Tool and AACODS (Authority, Accuracy, Coverage, Objectivity, Date, Significance) Checklist were used to evaluate the quality of the studies. Thematic analysis was used to present and synthesise results. This review was pre-registered on PROSPERO ( CRD42022343577). Results Twenty-two primary studies and ten government/industry publications were included in the analysis. Findings included gaps between practice and policy. Although identification of cognitive impairment, transparency of cognition information, and interaction with patients, families, and carers (if appropriate) about this condition were highly valued at a policy level, sometimes in practice, cognitive assessments were informal, patient cognition information was not recorded, and interactions with patients, families, and carers were lacking. Discussion By incorporating cognitive assessment, developing an integrated information management system using information technology, establishing relevant laws and regulations, providing education and training, and adopting a national approach, significant improvements can be made in the care provided to individuals with cognitive impairment.

Partnering with carers in the management of delirium in general acute care settings: An integrative review. Australas J Ageing 2023; 42:638-648. [PMID: 37528556 DOI: 10.1111/ajag.13229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 05/31/2023] [Accepted: 06/30/2023] [Indexed: 08/03/2023]
Abstract
OBJECTIVES Delirium is a common, preventable condition. However, delirium is poorly recognised and often missed because symptoms are misinterpreted, and risk factors overlooked by health-care professionals. Carers usually have intimate knowledge about the person they care for. Therefore, they are well placed within care teams to implement delirium prevention strategies, identify symptoms and support the early diagnosis of delirium. The aim of this integrative review was to synthesise findings from the published research reporting on partnering with carers in the management of delirium in general acute care settings. METHODS Five databases (Medline-EBSCO, PubMed, PsycINFO, ProQuest, CINAHL and SCOPUS) were searched to identify primary research regarding partnering with carers in the management of delirium in acute care settings, and results were synthesised. PRISMA guidelines were adhered to, and quality appraisal was conducted using the Mixed Methods Appraisal Tool. RESULTS All seven studies reported that partnering with carers was a viable strategy in the management of delirium to maximise outcomes for people at risk of or experiencing delirium and that increasing carers' knowledge of delirium was key. The synthesis of findings also identified two themes: Increasing knowledge and Effective partnerships. CONCLUSIONS A collaborative approach to increasing carers' and nurses' knowledge about the management of delirium, coupled with education on how to develop therapeutic nurse-carer relationships, is important for ongoing effective partnerships in the management of delirium. Good communication supported effective partnerships, which enabled both nurses and carers the opportunity to express their needs and concerns and negotiate collaborative involvement in the management of delirium.

Abstract
Background Unwarranted extended length of stay (LOS) increases the risk of hospital-acquired complications, morbidity, and all-cause mortality and needs to be recognized and addressed proactively. Objective This systematic review aimed to identify validated prediction variables and methods used in tools that predict the risk of prolonged LOS in all hospital admissions and specifically General Medicine (GenMed) admissions. Method LOS prediction tools published since 2010 were identified in five major research databases. The main outcomes were model performance metrics, prediction variables, and level of validation. Meta-analysis was completed for validated models. The risk of bias was assessed using the PROBAST checklist. Results Overall, 25 all admission studies and 14 GenMed studies were identified. Statistical and machine learning methods were used almost equally in both groups. Calibration metrics were reported infrequently, with only 2 of 39 studies performing external validation. Meta-analysis of all admissions validation studies revealed a 95% prediction interval for theta of 0.596 to 0.798 for the area under the curve. Important predictor categories were co-morbidity diagnoses and illness severity risk scores, demographics, and admission characteristics. Overall study quality was deemed low due to poor data processing and analysis reporting. Conclusion To the best of our knowledge, this is the first systematic review assessing the quality of risk prediction models for hospital LOS in GenMed and all admissions groups. Notably, both machine learning and statistical modeling demonstrated good predictive performance, but models were infrequently externally validated and had poor overall study quality. Moving forward, a focus on quality methods by the adoption of existing guidelines and external validation is needed before clinical application.

Aging Clin Exp Res 2023; 35:995-1003. [PMID: 37014618 PMCID: PMC10149476 DOI: 10.1007/s40520-023-02390-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 03/10/2023] [Indexed: 04/05/2023]
Abstract
BACKGROUND Postoperative delirium (POD) is a major complication following a surgical procedure. There is evidence that improving knowledge about POD could enhance POD care and patient outcomes. AIM The study aimed to evaluate whether the amount of delirium education among registered nurses working in post-anaesthetics care units (PACU) impacts on their self-reported confidence and competence in recognising and managing delirium as well as prior knowledge on factors that influence the risk of delirium onset for older people. METHOD The current study utilised an online survey on delirium care practice among registered nurses in PACUs. The survey consisted of 27 items. There were questions about confidence and competence in delirium care, knowledge about delirium risk factors, and ranked responses to two case scenario questions to evaluate the application of POD care. There were also demographic questions, including previous experience with delirium care education. RESULTS A total of 336 responses were generated from registered nurses working in PACU. Our findings found substantial variability among the respondents about their delirium care education. The amount of delirium education did not influence the PACU registered nurses' confidence or competence in delirium care. In addition, previous education did not have an impact on their knowledge about delirium risk factors. DISCUSSION AND CONCLUSION These findings suggested that the quantity of prior education about delirium did not improve the confidence, competence, knowledge, or case scenario questions of PACU registered nurses. Thus, delirium care education needs to be transformed to ensure it has a positive effect on delirium care clinical practice by registered nurses in PACU.

[PMID: 37109651 PMCID: PMC10141533 DOI: 10.3390/medicina59040693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 03/24/2023] [Accepted: 03/28/2023] [Indexed: 04/03/2023] Open
Abstract
Background and objectives: Delirium is the most prevalent psychiatric disorder in inpatient older people. Its presence is associated with higher rates of institutionalization, functional disability and mortality. This study aims to evaluate delirium in a hospitalized psychogeriatric population, focusing on which factors predict the appearance of delirium, the impact it generates and the diagnostic concordance between non-psychiatric physicians and psychiatrists. Material and methods: This is an observational, cross-sectional, retrospective, and comparative study. We obtained data from a sample of 1017 patients (≥65 years) admitted to general hospital and referred from different services to the consultation-liaison psychiatry (CLP) unit. Logistic regression was performed using delirium as the dependent variable. To estimate the concordance of the diagnoses, the Kappa coefficient was used. To assess the impact of delirium, an ordinal regression, Wilcoxon median test and Fisher’s test were performed. Results: Delirium is associated with a higher number of visits, OR 3.04 (95% CI 2.38–3.88), longer length of stay and mortality, OR 2.07 (95% CI, 1.05 to 4.10). The model to predict delirium shows that being >75 years old has an OR of 2.1 (95% CI, 1.59–2.79), physical disability has an OR of 1.66 (95% CI, 1.25–2.20), history of delirium has an OR of 10.56 (95% CI, 5.26–21.18) and no use of benzodiazepines has an OR of 4.24 (95% CI, 2.92–6.14). The concordance between the referring physician’s psychiatric diagnosis and the psychiatrist CLP unit showed a kappa of 0.30. When analysing depression and delirium, the concordance showed Kappa = 0.46. Conclusions: Delirium is a highly prevalent psychiatric disorder, but it is still underdiagnosed, with low diagnostic concordance between non-psychiatric doctors and psychiatrists from CLP units. There are multiple risk factors associated with the appearance of delirium, which must be managed to reduce its appearance.

[PMID: 37064025 PMCID: PMC10098316 DOI: 10.3389/fmed.2023.1071854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 02/10/2023] [Indexed: 04/18/2023] Open
Abstract
The burden of delirium in the intensive care setting is a global priority. Delirium affects up to 80% of patients in intensive care units; an episode of delirium is often distressing to patients and their families, and delirium in patients within, or outside of, the intensive care unit (ICU) setting is associated with poor outcomes. In the short term, such poor outcomes include longer stay in intensive care, longer hospital stay, increased risk of other hospital-acquired complications, and increased risk of hospital mortality. Longer term sequelae include cognitive impairment and functional dependency. While medical category of admission may be a risk factor for poor outcomes in critical care populations, outcomes for surgical ICU admissions are also poor, with dependency at hospital discharge exceeding 30% and increased risk of in-hospital mortality, particularly in vulnerable groups, with high-risk procedures, and resource-scarce settings. A practical approach to delirium prevention and management in the ICU setting is likely to require a multi-faceted approach. Given the good evidence for the prevention of delirium among older post-operative outside of the intensive care setting, simple non-pharmacological interventions should be effective among older adults post-operatively who are cared for in the intensive care setting. In response to this, the future ICU environment will have a range of organizational and distinct environmental characteristics that are directly targeted at preventing delirium.

Diagnostic accuracy of the 4AT for delirium: A systematic review and meta-analysis. Asian J Psychiatr 2023; 80:103374. [PMID: 36584541 DOI: 10.1016/j.ajp.2022.103374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 09/13/2022] [Accepted: 10/29/2022] [Indexed: 12/12/2022]
Abstract
INTRODUCTION Despite common, serious, costly, and often fatal conditions affecting up to 50 % of older patients, delirium is often unrecognized and overlooked. We examine the accuracy of the 4AT for detecting older patients with delirium. METHODS We performed a systematic search of PubMed, Web of Science, PsycINFO, and EMBASE databases from inception to April 2020 and updated to January 2022. Four independently reviewers extracted study data and assessed the methodological quality using the revised quality assessment of diagnostic accuracy studies tool (QUADAS-2). Pooled estimates of sensitivity and specificity were generated using a bivariate random effects model. All statistical analyses were performed with STATA version 15.1 and Meta-DiSc version 1.4 software. RESULTS Eleven studies with 2789 participants were included. The pooled sensitivity and specificity were 0.87 (95 % CI: 0.81-0.91) and 0.87 (95 % CI: 0.79-0.92), respectively, and the positive and negative likelihood ratios were 6.66 (95 % CI: 4.12-10.74) and 0.15 (95 % CI: 0.10-0.23), respectively. Deeks' test indicated no significant publication bias (t = 0.83, P = 0.43). Univariable meta-regression showed that patient selection and flow and timing significantly influenced the pooled sensitivity (P < 0.05), settings significantly influenced the pooled specificity (P < 0.05). CONCLUSION Our meta-analysis demonstrates that 4AT is a sensitive and specific screening tool for delirium in older patients. Its brevity and simplicity support its use in routine clinical practice, particularly in time-poor settings. Clinicians should come to a conclusion based largely on the 4AT findings in conjunction with clinical judgment.

Abstract
BACKGROUND Sepsis-associated encephalopathy (SAE) is a critical disease caused by sepsis. In addition to high mortality, SAE can also adversely affect life quality and lead to significant socioeconomic costs. This review aims to explore the development of evaluation animal models of SAE, giving insight into the direction of future research in terms of its pathophysiology and therapy. METHODS We performed a literature search from January 1, 2000, to December 31, 2022, in MEDLINE, PubMed, EMBASE, and Web of Science using related keywords. Two independent researchers screened all the accessible articles based on the inclusion and exclusion criteria and collected the relevant data of the studies. RESULTS The animal models for sepsis are commonly induced through cecal ligation and puncture (CLP) or lipopolysaccharide (LPS) injection. SAE can be evaluated using nervous reflex scores and sepsis evaluation during the acute phase, or through Morris water maze (MWM), open-field test, fear condition (FC) test, inhibitory avoidance, and other tests during the late phase. CONCLUSION CLP and LPS injection are the most common methods for establishing SAE animal models. Nervous reflexs cores, MWM, FC test, and inhibitory avoidance are widely used in SAE model analysis. Future research should focus on establishing a standardized system for SAE development and analysis.

Validation of Two Screening Tools for Detecting Delirium in Older Patients in the Post-Anaesthetic Care Unit: A Diagnostic Test Accuracy Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16020. [PMID: 36498093 PMCID: PMC9738308 DOI: 10.3390/ijerph192316020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/01/2022] [Revised: 11/28/2022] [Accepted: 11/29/2022] [Indexed: 06/17/2023]
Abstract
(1) Background: Delirium is a common complication among surgical patients after major surgery, but it is often underdiagnosed in the post-anaesthetic care unit (PACU). Valid and reliable tools are required for improving diagnoses of delirium. The objective of this study was to evaluate the diagnostic test accuracy of the Three-Minute Diagnostic Interview for Confusion Assessment Method (3D-CAM) and the 4A's Test (4AT) as screening tools for detection of delirium in older people in the PACU. (2) Methods: A prospective diagnostic test accuracy study was conducted in the PACU and surgical wards of a university-affiliated tertiary care hospital in Victoria, Australia. A consecutive prospective cohort of elective and emergency patients (aged 65 years or older) admitted to the PACU were recruited between July 2021 and December 2021 following a surgical procedure performed under general anaesthesia and expected to stay in the hospital for at least 24 h following surgery. The outcome measures were sensitivity, specificity positive predictive value and negative predictive value for 3D-CAM and 4AT. (3) Results: A total of 271 patients were recruited: 16.2% (44/271) had definite delirium. For a diagnosis of definite delirium, the 3D-CAM (area under curve (AUC) = 0.96) had a sensitivity of 100% (95% CI 92.0 to 100.0) in the PACU and during the first 5 days post-operatively. Specificity ranged from 93% (95% CI 87.8 to 95.2) to 91% (95% CI 85.9 to 95.2) in the PACU and during the first 5 days post-operatively. The 4AT (AUC = 0.92) had a sensitivity of 93% (95% CI 81.7 to 98.6) in the PACU and during the first 5 days post-operatively, and specificity ranged from 89% (95% CI 84.6 to 93.1) to 87% (95%CI 80.9 to 91.8) in the PACU and during the first 5 days post-operatively. (4) Conclusions: The 3D-CAM and the 4AT are sensitive and specific screening tools that can be used to detect delirium in older people in the PACU. Screening with either tool could have an important clinical impact by improving the accuracy of delirium detection in the PACU and hence preventing adverse outcomes associated with delirium.

Abstract
Delirium- an acute disorder of attention and cognition- is the commonest complication following hip fracture. Patients with hip fracture are particularly vulnerable to delirium, and many of the lessons from the care of the patient with hip fracture will extend to other surgical cohorts. Prevention and management of delirium for patients presenting with hip fracture, extending along a continuum from arrival through to the post-operative setting. Best practice guidelines emphasize multidisciplinary care including management by an orthogeriatric service, regular delirium screening, and multimodal interventions. The evidence base for prevention is strongest in terms of multifaceted interventions, while once delirium has set in, early recognition and identification of the cause are key. Integration of effective strategies is often suboptimal, and may be supported by approaches such as interactive teaching methodologies, routine feedback, and clear protocol dissemination. Partnering with patients and carers will support person centered care, improve patient experiences, and may improve outcomes. Ongoing work needs to focus on implementing recognized best practice, in order to minimize the health, social and economic costs of delirium.

Abstract
BACKGROUND Each year, thousands of older adults develop delirium, a serious, preventable condition. At present, there is no well-validated method to identify patients with delirium when using Medicare claims data or other large datasets. We developed and assessed the performance of classification algorithms based on longitudinal Medicare administrative data that included International Classification of Diseases, 10th Edition diagnostic codes. METHODS Using a linked electronic health record (EHR)-Medicare claims dataset, 2 neurologists and 2 psychiatrists performed a standardized review of EHR records between 2016 and 2018 for a stratified random sample of 1002 patients among 40,690 eligible subjects. Reviewers adjudicated delirium status (reference standard) during this 3-year window using a structured protocol. We calculated the probability that each patient had delirium as a function of classification algorithms based on longitudinal Medicare claims data. We compared the performance of various algorithms against the reference standard, computing calibration-in-the-large, calibration slope, and the area-under-receiver-operating-curve using 10-fold cross-validation (CV). RESULTS Beneficiaries had a mean age of 75 years, were predominately female (59%), and non-Hispanic Whites (93%); a review of the EHR indicated that 6% of patients had delirium during the 3 years. Although several classification algorithms performed well, a relatively simple model containing counts of delirium-related diagnoses combined with patient age, dementia status, and receipt of antipsychotic medications had the best overall performance [CV- calibration-in-the-large <0.001, CV-slope 0.94, and CV-area under the receiver operating characteristic curve (0.88 95% confidence interval: 0.84-0.91)]. CONCLUSIONS A delirium classification model using Medicare administrative data and International Classification of Diseases, 10th Edition diagnosis codes can identify beneficiaries with delirium in large datasets.

A nurse-led intervention to reduce the incidence and duration of delirium among adults admitted to intensive care: A stepped-wedge cluster randomised trial. Aust Crit Care 2022:S1036-7314(22)00115-1. [PMID: 36182540 DOI: 10.1016/j.aucc.2022.08.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 07/24/2022] [Accepted: 08/06/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Delirium is an acute change in behaviour, characterised by a fluctuating course, inattention, and disorganised thinking. For critically ill adults in the intensive care, the incidence of delirium has been reported to be at least 30% and is associated with both short-term and long-term complications, longer hospital stay, increased risk of mortality, and long-term cognitive problems. AIM The objective of this study was to determine the effectiveness of a nurse-led delirium-prevention protocol in reducing the incidence and duration of delirium among adults admitted to intensive care. METHODS A hybrid stepped-wedge cluster randomised controlled trial was conducted to assess the effectiveness of the implementation and dissemination of the nurse-led intervention to reduce the incidence and duration of delirium among adults admitted to the four adults intensive care units in the southwest of Sydney, Australia. RESULTS Between May 2019 and February 2020, over a 10-month period, 2618 admissions, among 2566 patients, were included in the study. After an initial 3-month baseline period, each month there was a random crossover to the nurse-led intervention in one of the four intensive care units, and by the 7th month of the trial, all units were exposed to the intervention for at least 3 months. The incidence of acute delirium was observed to be 10.7% (95% confidence interval [CI] = 9.1-12.4%), compared to 14.1% (95% CI = 12.2-16.2%) during the preintervention (baseline) period (adjusted rate ratio [adjRR] = 0.78, 95% CI = 0.57-1.08, p = 0.134). The average delirium-free-days for these preintervention and postintervention periods were 4.1 days (95% CI = 3.9-4.3) and 4.4 days (95% CI = 4.2-4.5), respectively (adjusted difference = 0.24 days [95% CI = -0.12 to 0.60], p = 0.199). CONCLUSION Following the introduction of a nurse-led, nonpharmacological intervention to reduce the burden of delirium, among adults admitted to intensive care, we observed no statistically significant decrease in the incidence of delirium or the duration of delirium.

Abstract
OBJECTIVES Delirium commonly occurs during hospitalisation and is associated with increased mortality, especially in elderly patients. This study aimed to determine the demographic and clinical characteristics of patients with delirium in the Japanese real-world clinical setting using a nationwide database comprising claims and discharge abstract data. DESIGN This was an observational, cross-sectional, retrospective study in hospitalised patients with an incident delirium identified by a diagnosis based on International Classification of Diseases, 10th Revision codes or initiating antipsychotics recommended for delirium treatment in Japan during their hospitalisation. SETTING Patients from the Medical Data Vision database including more than 400 acute care hospitals in Japan were evaluated from admission to discharge. PARTICIPANTS Of the 32 910 227 patients who were included in the database between April 2012 and September 2020, a total of 145 219 patients met the criteria for delirium. PRIMARY AND SECONDARY OUTCOME MEASURES Demographic and baseline characteristics, comorbidities, clinical profiles and pharmacological treatments were evaluated in patients with delirium. RESULTS The mean (SD) patient age was 76.5 (13.8) years. More than half of the patients (n=82 159; 56.6%) were male. The most frequent comorbidities were circulatory system diseases, observed in 81 954 (56.4%) patients. Potentially inappropriate medications (PIMs) with risk of delirium including benzodiazepines and opioids were prescribed to 76 798 (52.9%) patients. Approximately three-fourths of these patients (56 949; 74.2%) were prescribed ≥4 PIMs. The most prescribed treatment for delirium was injectable haloperidol (n=82 490; 56.8%). Mean (SD) length of hospitalisation was 16.0 (12.1) days. CONCLUSIONS The study results provide comprehensive details of the clinical characteristics of patients with delirium and treatment patterns with antipsychotics in the Japanese acute care setting. In this patient population, the prescription rate of injectable haloperidol and PIMs was high, suggesting the need for improved understanding among healthcare providers about the appropriate management of delirium, which may benefit patients.

Abstract
INTRODUCTION Postoperative delirium is common in older cardiac surgery patients and associated with negative short-term and long-term outcomes. The alpha-2-adrenergic receptor agonist dexmedetomidine shows promise as prophylaxis and treatment for delirium in intensive care units (ICU) and postoperative settings. Clonidine has similar pharmacological properties and can be administered both parenterally and orally. We aim to study whether repurposing of clonidine can represent a novel treatment option for delirium, and the possible effects of dexmedetomidine and clonidine on long-term cognitive trajectories, motor activity patterns and biomarkers of neuronal injury, and whether these effects are associated with frailty status. METHODS AND ANALYSIS This five-centre, double-blind randomised controlled trial will include 900 cardiac surgery patients aged 70+ years. Participants will be randomised 1:1:1 to dexmedetomidine or clonidine or placebo. The study drug will be given as a continuous intravenous infusion from the start of cardiopulmonary bypass, at a rate of 0.4 µg/kg/hour. The infusion rate will be decreased to 0.2 µg/kg/hour postoperatively and be continued until discharge from the ICU or 24 hours postoperatively, whichever happens first.Primary end point is the 7-day cumulative incidence of postoperative delirium (Diagnostic and Statistical Manual of Mental Disorders, fifth edition). Secondary end points include the composite end point of coma, delirium or death, in addition to delirium severity and motor activity patterns, levels of circulating biomarkers of neuronal injury, cognitive function and frailty status 1 and 6 months after surgery. ETHICS AND DISSEMINATION This trial is approved by the Regional Committee for Ethics in Medical Research in Norway (South-East Norway) and by the Norwegian Medicines Agency. Dissemination plans include publication in peer-reviewed medical journals and presentation at scientific meetings. TRIAL REGISTRATION NUMBER NCT05029050.

[PMID: 35436596 DOI: 10.1016/j.ijnurstu.2022.104191] [Citation(s) in RCA: 42] [Impact Index Per Article: 21.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Revised: 01/24/2022] [Accepted: 02/04/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Pressure injuries are a leading hospital adverse event, yet they are mostly preventable. Understanding their financial costs will help to appreciate the burden they place on the health system and assist in better planning and management of health expenditures to prevent pressure injuries. OBJECTIVE To estimate the cost of pressure injuries in Australian public hospitals in 2020 demonstrating its economic burden in a well-resourced health system. METHODS A cost of illness study with a 12-month time horizon was conducted. Resource use for the treatment of pressure injuries and productivity loss due to pressure injuries were derived using a bottom-up approach. Parameters of the cost estimates were obtained from secondary sources and literature syntheses. A simulation with 10,000 draws was used to generate statistical properties of the cost estimates. RESULTS Based on a prevalence of 12.9%, the total cost of pressure injuries in Australian public hospitals was $9.11 billion [95% confidence intervals: 9.02, 9.21]. The two largest shares of costs were accounted for by the opportunity cost of excess length of stay of $3.60 billion [3.52, 3.68] and treatment costs of $3.59 billion [3.57, 3.60]. Productivity loss associated with pressure injuries amounts to $493 million [482, 504]. Hospital-acquired pressure injuries account for a total of $5.50 billion [5.44, 5.56], whereas pressure injuries present on admissions costed $3.71 billion [3.70, 3.72]. In terms of severity, Stage 2 pressure injuries contributed the most to total treatment costs, total excessive length of stay, and total loss of healthy life years. Australian society is willing to pay $1.43 billion [1.40, 1.45] to save 6,701 [6,595; 6,807] healthy life years lost by pressure injury. CONCLUSIONS Reducing preventable pressure injuries and stopping the progression of Stage 1 pressure injuries will likely result in an immense cost-saving for Australia and will likely have similar benefits for other countries with comparable profiles. TWEETABLE ABSTRACT Australian public hospital study provides comprehensive analysis of the cost of pressure injury, including estimates of direct and indirect medical costs, and indirect non-medical costs - such as productivity and quality of life.

Non-Pharmacological Nursing Interventions to Prevent Delirium in ICU Patients-An Umbrella Review with Implications for Evidence-Based Practice. J Pers Med 2022; 12:760. [PMID: 35629183 PMCID: PMC9143487 DOI: 10.3390/jpm12050760] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 05/02/2022] [Accepted: 05/05/2022] [Indexed: 02/06/2023] Open
Abstract
Delirium in ICU patients is a complication associated with many adverse consequences. Given the high prevalence of this complication in critically ill patients, it is essential to develop and implement an effective management protocol to prevent delirium. Given that the cause of delirium is multifactorial, non-pharmacological multicomponent interventions are promising strategies for delirium prevention. (1) Background: To identify and evaluate published systematic review on non-pharmacological nursing interventions to prevent delirium in intensive care unit patients. (2) Methods: An umbrella review guided by the Joanna Briggs Institute was utilized. Data were obtained from PubMed, Scopus, EBSCO, Web of Science, Cochrane Library, and Google Scholar. The last search was conducted on 1 May 2022. (3) Results: Fourteen reviews met the inclusion criteria. Multicomponent interventions are the most promising methods in the fight against delirium. The patient's family is an important part of the process and should be included in the delirium prevention scheme. Light therapy can improve the patient's circadian rhythm and thus contribute to reducing the incidence of delirium. (4) Conclusions: Non-pharmacological nursing interventions may be effective in preventing and reducing the duration of delirium in ICU patients.

Effects of non-pharmacological interventions for preventing delirium in general ward inpatients: A systematic review & meta-analysis of randomized controlled trials. PLoS One 2022; 17:e0268024. [PMID: 35522654 PMCID: PMC9075647 DOI: 10.1371/journal.pone.0268024] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 04/21/2022] [Indexed: 11/29/2022] Open
Abstract
The purpose of this study was to identify the types and contents of non-pharmacological delirium prevention interventions applied to inpatients in general wards, and to verified the effectiveness of the interventions on the incidence of delirium. We performed an extensive search of bibliographic databases and registries (CENTRAL, MEDLINE, EMBASE, CINAHL, ClinicalTrials.gov and WHO International Clinical Trials Registry Platform, PubMed and Google Scholar, and Korean DB such as RISS, DBpia, KISS, NDSL and KCI) using terms to identify delirium, prevention, and non-pharmacological. We searched all databases from their inception to January 2021 and imposed restriction on language of publication in English and Korean. We included studies if they were conducted as all types of randomized controlled trials (RCT), involving adult patients aged 19 years or more who were admitted to a general ward. We included trials comparing non-pharmacological intervention versus usual care. The entire process of data selection and extraction, assessment of risk of bias with ROB2.O was independently performed by three researchers. The estimated effect size was an odds ratio (OR) and 95% confidence interval. The fixed effects model and general inverse variance estimation method were adopted. The type of non-pharmacological delirium prevention interventions for inpatients in general ward was mainly multi-component intervention to correct delirium risk factors. The content and intensity of non-pharmacological interventions varied greatly depending on the characteristics of the patient and the clinical situation. As a result of the meta-analysis, non-pharmacological multi-component intervention was effective in reducing the incidence of delirium, and it was confirmed that it was effective in reducing the incidence of delirium in both the internal and surgical wards. It was confirmed by quantitative evidence that non-pharmacological interventions, especially multi-component interventions, were effective in preventing delirium in general ward inpatients.

Abstract
PURPOSE OF REVIEW Delirium is a common and important adverse event in the perioperative period. Older people with cancer are at significant risk, and outcomes are poor. There is increasing awareness of the effect of psychological distress and social support on pathogenesis and outcomes of delirium in this setting. This review aimed to describe recent research in this evolving area. RECENT FINDINGS Across six recent studies of postoperative delirium in older people with cancer, delirium incidence ranged from 8 to 19.8%. Poor social support and high levels of distress are implicated in the development of postoperative delirium. Distress can be related to negative emotional reaction to diagnosis, preconception of cancer diagnosis and interactions with the healthcare system. Prevention of delirium is key, and multicomponent interventions show evidence of effectiveness. 'Emotional distress' has been included in a new core outcome set for studies of interventions to prevent and/or treat delirium. SUMMARY Postoperative delirium in older adults with cancer is common and is associated with increased morbidity and mortality. Psychological distress and social support play an important role, but there are many unmet research needs in this area.

Abstract
Objective to evaluate the sensitivity, specificity and test–retest reliability of the Delirium Early Monitoring System-Delirium Observation Screening Scale (DEMS-DOSS). Design prospective diagnostic accuracy study of a convenience sample of admitted older adults with DEMS-DOSS and reference standard assessments. Setting 60-bed aged care precinct at a metropolitan hospital in Sydney, Australia. Participants 156 patients (aged ≥65 years old) were recruited to participate between April 2018 and March 2020. One hundred participants were included in the analysis. Measurements Participants were scored on the DEMS-DOSS. Trained senior aged care nurses conducted a standardised clinical interview based on the Diagnostic and Statistical Manual of Mental Disorder (DSM)-IV delirium criteria, within two hours of DEMS-DOSS completion. The senior aged care nurse undertaking the DSM-IV interview was blinded to the results of the DEMS-DOSS. Results Participants’ mean age was 84 (SD ±7.3) years and 39% (n = 39) had a documented diagnosis of dementia. Delirium was detected in 38% (n = 38) according to the reference standard. The DEMS-DOSS had a sensitivity of 76.3% and a specificity of 75.8% for delirium. The area under the receiver operating characteristics curve for delirium was 0.76. The test–retest reliability of the DEMS-DOSS was found to be high (r = 0.915). Conclusion DEMS-DOSS is a sensitive and specific tool to assist with monitoring new onset and established delirium in hospitalised older adults. Further studies are required to evaluate the impact of the monitoring tool on health outcomes.

Abstract
INTRODUCTION Delirium is a neurocognitive disorder common in older adults in acute care settings. Those who develop delirium are at an increased risk of dementia, cognitive decline and death. Electroencephalography (EEG) during delirium in older adults is characterised by slowing and reduced functional connectivity, but markers of vulnerability are poorly described. We aim to identify EEG spectral power and event-related potential (ERP) markers of incident delirium in older adults to understand neural mechanisms of delirium vulnerability. Characterising delirium vulnerability will provide substantial theoretical advances and outcomes have the potential to be translated into delirium risk assessment tools. METHODS AND ANALYSIS We will record EEG in 90 participants over 65 years of age prior to elective coronary artery bypass grafting (CABG) or transcatheter aortic valve implantation (TAVI). We will record 4-minutes of resting state (eyes open and eyes closed) and a 5-minute frequency auditory oddball paradigm. Outcome measures will include frequency band power, 1/f offset and slope, and ERP amplitude measures. Participants will undergo cognitive and EEG testing before their elective procedures and daily postoperative delirium assessments. Group allocation will be done retrospectively by linking preoperative EEG data according to postoperative delirium status (presence, severity, duration and subtype). ETHICS AND DISSEMINATION This study is approved by the Human Research Ethics Committee of the Royal Adelaide Hospital, Central Adelaide Local Health Network and the University of South Australia Human Ethics Committee. Findings will be disseminated through peer-reviewed journal articles and presentations at national and international conferences.

Abstract
Delirium is a common neurocognitive disorder in hospitalised older adults with substantial negative consequences. Impaired global cognition is a well-established delirium risk factor. However, poor performance on attention tests and higher intra-subject variability may be more sensitive delirium risk factors, given the disorder is characterised by a fluctuating course and attentional deficits. We systematically searched databases (Embase, PsycINFO, MEDLINE) and 44 studies satisfied inclusion criteria. Random-effects meta-analysis models showed poor performance in all cognitive domains except perception was significantly associated with incident delirium. Largest effects were for orientation (g=-1.20) and construction and motor performance (g=-0.60). These effects were no longer significant in the subgroup without pre-existing cognitive impairment, where executive functions and verbal functions and language skills were associated with incident delirium. A small, non-significant association between intra-subject variability and incident delirium was found (g=0.42). Cognitive domain specific tests may be quicker and more sensitive predictors of incident delirium. This pattern of neuropsychological findings supports the proposition that vulnerability for delirium manifests as a dysfunction of whole-brain information integration.

Abstract
Delirium is one of the common manifestations of acute brain dysfunction in critically ill patients. We aimed to evaluate the effect of family intervention on reducing the delirium incidence in patients hospitalized in the intensive care unit (ICU). We searched electronic databases for randomized clinical trials, cohort, and before-and-after studies up to September 2021 using the MeSH terms ("family" OR "family caregiver") AND ("delirium"). A total of 6 studies including 4199 patients were analyzed. Compared to the control group, the risk of delirium was 24% lower in the family intervention group (OR 0·76 [0·67-0·86], P = 0.20, I2 = 31%). Pooled data from two trials showed that family intervention was associated with fewer delirium days (SMD: -1.13, 95% CI: -1.91 to -0.34; P = 0.08; I2 = 67%;). However, there were no significant differences between the two groups in the length of ICU stay, mechanical ventilation duration, and mortality (ICU stay days: MD: -0.62 days; 95% CI: -1.49 to 0.24; P = 0.14; I2 = 72%; mechanical ventilation days: MD: -0.48 days; 95% CI: -2.10 to 1.13; P = 0.56; I2 = 0%; mortality: OR: 0.68, 95% CI: 0.22 to 2.09; P = 0.08; I2 = 67%). Current evidence supports the use of family intervention in reducing the delirium risk and delirium days in hospitalized ICU patients. However, its effects on reducing ICU stay length, ventilation duration, and mortality require further study. Future research should consider identifying the specific family intervention strategies and their duration.

Diagnostic accuracy and clinical applicability of the Swedish version of the 4AT assessment test for delirium detection, in a mixed patient population and setting. BMC Geriatr 2021; 21:568. [PMID: 34663229 PMCID: PMC8522056 DOI: 10.1186/s12877-021-02493-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Accepted: 09/23/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Delirium is common in older hospitalized patients. It has serious consequences e.g., poor health outcomes, mortality and increased costs. Despite that, many cases are undetected. Early detection of delirium is important in improving outcomes and use of assessment tools improves detection rates. The 4AT is a brief screening tool for delirium detection, which has not previously been translated into Swedish. The study aim was to evaluate diagnostic accuracy and clinical applicability of a Swedish version of the screening tool 4AT for delirium detection. METHOD This diagnostic test accuracy study used a quantitative and a qualitative approach and evaluated the patients' and the health care professionals' experiences of the tool. Study included 200 patients ≥65 years from a university hospital and a county hospital in two Swedish regions. Medical specialties were geriatric stroke/neurology, geriatric multimorbidity, severe cognitive impairment, orthopaedic, and urology. The translated 4AT was tested against the reference standard DSM-IV-TR criteria, based on the Organic Brain Syndrome scale and patient records. The 4AT was assessed simultaneously and independently by two assessors. Additionally, data was collected through patient record reviews, and questions about applicability to the patients (n = 200) and the assessors (n = 37). Statistical analyses, and qualitative content analyses were conducted. RESULTS By reference standard 18% had delirium, and by 4AT 19%. The overall percent agreement was 88%, AUROC 0.808, sensitivity 0.70 (95% CI 0.51-0.84) and specificity 0.92 (95% CI 0.87-0.96). In the ward for severe cognitive impairment (n = 63) the 4AT was less sensitive and less specific. In the other wards (n = 132) sensitivity was 0.77 (95% CI 0.50-0.93), specificity 0.93 (95% CI 0.87-0.97), and AUROC 0.848. Interrater reliability (Kappa) was 0.918, p = < 0.001 (n = 144). The 4AT was well tolerated by patients, easy to use for health care professionals, and took a few minutes to conduct. CONCLUSION The Swedish version of 4AT is an accurate and applicable tool to use in clinical practice for detecting delirium in hospitalized patients across different medical specialities, and to use by different professionals and levels of seniority. To improve patient outcomes, we recommend the 4AT to be incorporated in clinical practice in health care settings in Sweden.

A study to improve delirium care. Int J Qual Health Care 2021; 33:6101164. [PMID: 33449113 DOI: 10.1093/intqhc/mzab006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 11/30/2020] [Accepted: 01/13/2021] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Delirium is commonly detected in older people after hip fracture. Delirium is considered to be a multifactorial disorder that is often seen post-operatively (incidence ranging from 35% to 65%). Hospitals in Australia are required to meet eight standards including the comprehensive care standard to be able to maintain their accreditation. The standard includes actions related to falls, pressure injuries, nutrition, mental health, cognitive impairment and end-of-life care. Delirium prevention was identified as an area for improvement in our Orthopaedic unit in a Level 1 University Trauma Centre in Australia. This implementation research project aimed to understand the efficacy of a delirium prevention intervention within an existing orthopaedic speciality care system. OBJECTIVE Implementation of the tailored intervention will increase adherence to National Safety and Quality Health Service Standards, thereby reducing rate of delirium. METHODS In this study, we used an interrupted time series design to examine changes in practice over time in people admitted to hospital with a hip fracture. Clinical staff caring for patients with hip fracture in an acute care setting in Adelaide, South Australia, participated in the project. In brief, intervention included education, environmental restructuring, change champions, infographics and audit feedback reports. The primary outcome of interest was rate of delirium. The secondary outcome was compliance with the use of delirium 4AT screening tool, duration of delirium and hospital length of stay. RESULTS The rate of change per month in patients with delirium decreased significantly by 19.2%. There was no significant change observed in trend for duration of delirium and length of hospital stay between pre-intervention and post-intervention phases. A significant increase in the use of screening tool was observed from 4.7% in the pre-intervention phase to 33.6% in the post-intervention phase. CONCLUSION Translation of evidence-based intervention model incorporating well-considered implementation strategies had a mixed impact on decreasing the rate of delirium. The scheduled hospital accreditation enhanced the use of validated screening tool to recognize delirium. This project highlights the importance of aligning implementation goals with the wider goals of the organization as well as making clinicians accountable by consistent auditing.

Abstract
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.

Abstract
Delirium occurring in a patient with preexisting dementia is referred to as delirium superimposed on dementia (DSD). DSD commonly occurs in older hospitalized patients and is associated with worse outcomes, including higher rates of mortality and institutionalization, compared to inpatients with delirium or dementia alone. This narrative review summarizes the screening, diagnosis, management, and pathophysiology of DSD and concludes by highlighting opportunities for future research. Studies were identified via Medline and PsycINFO keyword search, and handsearching reference lists. Conceptually, DSD could be considered an "acute exacerbation" of dementia precipitated by a noxious insult akin to an acute exacerbation of heart failure or acute on chronic renal failure. However, unlike other organ systems, there are no established biomarkers for delirium, so DSD is diagnosed and monitored clinically. Because cognitive dysfunction is common to both delirium and dementia, the diagnosis of DSD can be challenging. Inattention, altered levels of arousal, and motor dysfunction may help distinguish DSD from dementia alone. An informant history suggestive of an acute change in cognition or alertness should be investigated and managed as delirium until proven otherwise. The key management principles include prevention, identifying and treating the underlying precipitant(s), implementing multicomponent interventions to create an ideal environment for brain recovery, preventing complications, managing distress, and monitoring for resolution. Informing and involving family members or caregivers throughout the patient journey are essential because there is significant prognostic uncertainty, including the risk of persistent cognitive and functional decline following DSD and relapse. Furthermore, informal carers can provide significant assistance in management. Emerging evidence demonstrates that increased exposure to delirium is associated with neuronal injury and worse cognitive outcomes although the mechanisms through which this occurs remain unclear. Given the clinical overlap between delirium and dementia, studying shared pathophysiological pathways may uncover diagnostic tests and is an essential step in therapeutic innovation.

Abstract
Background Despite the prevalence and impact of delirium, its pathophysiology remains unclear. In order to advance this field of research, robust scientific methodology is required, yet quality of reporting in this field of research has been highly inconsistent. Delirium biomarker research poses several challenges, none of which have been documented in the literature before. The aim of this study was to explore the perspectives of delirium researchers about key methodological issues in delirium biomarker research. Methods Following a Delphi study with delirium experts resulting in 60 recommendations for reporting delirium biomarker studies, semi-structured interviews with international delirium researchers were conducted. Interviews were audio-taped and transcribed verbatim, followed by thematic analysis of the qualitative data. Results Fifteen participants were interviewed between August and November 2019. Most were male (n = 12; 75%), clinician researchers (n = 13; 86%), and had more than ten years’ experience in conducting delirium research (n = 9; 60%). Analysis revealed two major themes and ten sub-themes, outlining key considerations to advance the field of delirium biomarker research. The major themes were: 1) Practical and scientific challenges of delirium biomarker research: stagnation versus driving improved methods and reporting; and 2) Valuing delirium research through investment and collaboration. Conclusion Findings identified a range of factors that contribute to the practical and ethical challenges of conducting delirium biomarker research, which have not previously been explicitly acknowledged or reported. A clear vision for collaborative efforts to enhance research quality for improved impact was also presented by the delirium researchers. This work complements the preceding Delphi and together these studies provide an in-depth understanding of what is needed in the field to inform and improve methods and reporting of delirium biomarker research.

Abstract
Aim Investigate if 4AT score predicts 1 year mortality and explore the sensitivity and specificity of the 4AT when applied as part of a clinical routine. Findings 4AT score is one of several clinical characteristics predicting 1 year mortality. The 4AT has reasonable sensitivity and specificity to detect delirium in a clinical routine setting. Message The 4AT seems to be a useful tool for delirium screening and may predict mortality. Purpose Delirium is common and associated with poor outcomes, partly due to underdetection. We investigated if the delirium screening tool 4 A’s test (4AT) score predicts 1 year mortality and explored the sensitivity and specificity of the 4AT when applied as part of a clinical routine. Methods Secondary analyses of a prospective study of 228 patients acutely admitted to a Medical Geriatric Ward. Physicians without formal training conducted the index test (the 4AT); a predefined cut-off ≥ 4 suggested delirium. Reference standard was delirium diagnosed by two geriatricians using the Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5). We calculated hazard ratios (HR) using Cox regression based on the groups 4AT = 0, 1–3, 4–7 and ≥ 8, first unadjusted, then adjusted for the covariates age, comorbidity, and personal activities of daily living. We calculated sensitivity, specificity, and the area under the receiver operating curve (AUC). Results Mean age of patients was 86.6 years, 139 (61.0%) were female, 78 (34.2%) had DSM-5 delirium; of these, 56 had 4AT-delirium. 1 year mortality was 27.6% (63 patients). Compared to 4AT score 0, the group 4AT ≥ 8 had increased 1 year mortality (HR 2.86, 95% confidence interval 1.28–6.37, p = 0.010). The effect was reduced in multiadjusted analyses (HR 1.69, 95% confidence interval 0.70–4.07, p = 0.24). Sensitivity, specificity, and AUC were 0.72, 0.84, and 0.88, respectively. Conclusions 4AT ≥ 8 indicates increased mortality, but the effect was reduced in multiadjusted analyses. 4AT had acceptable sensitivity and specificity when applied as a clinical routine.

Abstract
OBJECTIVES To examine nationwide trends in delirium mortality in Australia and the United States between 2006 and 2016. METHODS Delirium mortality data for Australian and United States populations were obtained from World Health Organization Mortality Database. Mortality trends were assessed using joinpoint regression. RESULTS Age-adjusted delirium mortality increased by 16.35%/year and 4.04%/year in Australia and the United States, respectively. Average annual age-adjusted delirium mortality rate (per 1 000 000 population) was 2.90 in Australia, and 1.06 in the United States. Death rates from delirium increased with age. Mortality was consistently higher in men than women, but the rate of annual increase was greater in women. CONCLUSIONS Our study provided important population-level data on delirium and its outcomes in Australia and the United States. Reported death rates attributed to delirium increased over the 11-year period in both countries and were consistently higher in Australia than the United States. There were distinct age and sex differences in mortality trends.

Abstract
INTRODUCTION This review aims to systematically identify and appraise the methodological quality of claims on the cost of delirium; and discuss challenges and opportunities for improvements in the precision of the estimates. METHODS Searches of scientific papers and gray literature were performed up until June 2020. The Larg and Moss checklist was used to assess the methodological quality of the included studies. RESULTS After deduplication, the search identified 317 potentially relevant articles, of which 17 articles were eligible for inclusion. After adjusting for inflation and common currency, the cost of delirium ranged between $806 and $24,509 (in 2019 US$). DISCUSSION This review found significant variation among the cost estimates and methodological quality. There has been limited focus on dementia as a sequela of delirium in terms of economic implications, but recent evidence suggests cost implications of delirium may be 52% higher when dementia is considered.

Abstract
General anesthesia has been administered for over 150 years, and in that time, has become progressively safer. Improvements in outcomes have been driven by multiple advances, including the use of non-invasive monitors to assess cardiovascular and respiratory status. More recent advances have included the development and use of monitors to measure neurologic status by means of “processed” electroencephalography (pEEG), wherein the frontal EEG signal is analyzed by proprietary algorithms to produce a dimensionless number (scaled from 0 to 100), wherein low values are associated with deepening levels of sedation that progresses to loss of consciousness. Such monitors have been shown to enable anesthetic titration so as to expedite emergence and early recovery, and their use is advocated for the prevention of intraoperative awareness in the setting of administration of total intravenous anesthesia and neuromuscular blockade. Whether their use can minimize, or prevent, longer term adverse events is a matter of debate. In this narrative review of the most recent literature, we provide an assessment on the use of pEEG monitors in the prevention of a notable, and important, postoperative adverse outcome – delirium – in elderly patients. As we will discuss, the existing data do not support its routine use for the prevention of postoperative delirium in this, or any other, patient population.

Abstract
BACKGROUND Delirium is a frequently encountered complication, which is associated with increased mortality. Suvorexant, an approved agent for the treatment of insomnia, is recently suggested to be also effective for prevention of delirium by some authors. However, a consensus has yet to be reached. The goal of this study was to perform a meta-analysis to overall estimate the effectiveness of suvorexant in preventing delirium and its related consequences. METHODS Eligible studies were identified by searching online databases of PubMed, EMBASE, and Cochrane Library. The pooled OR was calculated for binary outcomes (e.g., the incidence of delirium, mortality, or adverse events), while standardized mean difference (SMD) were expressed for continuous outcomes (e.g., time to delirium onset, length of stay in hospital and ICU, time on ventilation). RESULTS Seven studies which comprised 402 suvorexant treatment patients and 487 patients with control treatment were included in this meta-analysis. Overall, pooled analysis indicated the incidence of delirium could be significantly reduced (OR, 0.30; P < .001) and time to delirium onset was significantly lengthened (SMD, 0.44; P = .006) in patients undergoing suvorexant treatment compared with controls. Suvorexant had no beneficial effects on the secondary outcomes [length of stay in hospital (SMD, -0.65; P = .161) and ICU (SMD, 0.34; P = .297), time on ventilation (SMD, 1.09; P = .318), drug-related adverse events (OR, drug-related adverse events (OR, 1.66; P = .319) and mortality (OR, 2.21; P = .261)]. Subgroup analysis also confirmed the benefit of suvorexant on the development of delirium, which was significant in any subgroup. CONCLUSION Suvorexant should be recommended for the prevention of delirium in clinic.

Abstract
BACKGROUND Delirium is a serious and distressing neurocognitive condition common in people with advanced illness. The understanding of delirium pathophysiology is limited and largely hypothetical. To accelerate empirical understanding of delirium pathophysiology, robust scientific methods for conducting and reporting delirium biomarker studies are urgently needed. The aim of this study was to develop international consensus on the core elements of high-quality delirium biomarker studies. METHODS A three-round modified Delphi survey was conducted from February to August 2019. Participants were international researchers experienced in conducting delirium studies from a range of settings (hospital, university, research centres). Round one commenced with open-ended questions developed from results from a prior systematic review and the REMARK (REporting recommendations for tumour MARKer prognostic studies) checklist. Responses were qualitatively analysed, and closed statements were developed. Participants then ranked the importance of these statements using a 5-point Likert scale in rounds 2 and 3. A priori consensus was defined as ≥70% participant agreement. Descriptive statistics for each item were computed including the mean Likert scores, SD and median participant scores. RESULTS Twenty-eight participants completed survey round one, 16 completed round two and 19 completed the final round. Consensus was achieved for a total of 60 items. CONCLUSION The Delphi survey identified items that expert researchers agreed were important in the conduct of delirium biomarker studies. These reporting items provide a strong platform for improved methodological quality and opportunities to synthesise future delirium biomarker studies.

Results from a register-based case-control study. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2020; 122:62-69. [PMID: 32302798 DOI: 10.1016/j.jormas.2020.04.002] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Accepted: 04/06/2020] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To identify risk factors for postoperative delirium (POD) after general oral and maxillofacial surgery. MATERIAL AND METHODS 2420 patients were screened postoperatively for POD using the Nursing Delirium Screening Scale (NuDESC) before discharge from the post anesthesia caring unit (PACU). Basic health data and risk factors were collected. For analysis the study group (n=41) was compared to a control group of 164 randomly selected patients (case-control-ratio=1:4). To identify risk factors for POD multivariable logistic regression models were used. To see whether estimations remain stable, regression analysis was repeated for the subgroup of patients not undergoing dentoalveolar surgery (n=105). To estimate the risk for dentoalveolar surgery a logistic regression model was performed. RESULTS Dementia was the only significant risk factor for POD (Odds ratio 41.5; 95% CI 5.48-314), also for patients undergoing other than dentoalveolar surgery (58.1; 1.70-1983). Patients undergoing dentoalveolar surgery were more often suffering from dementia (35.5; 2.85-441), other psychiatric and neurological disorders (3.15; 1.05-9.43), were of younger age (0.97; 0.94-1.00) and had higher anesthesiological risk (3.95; 1.04-14.9). CONCLUSION Patients with dementia are at higher risk to develop POD after oral and maxillofacial surgery. We found a strong interdependence between age, dementia, ASA-Score and dentoalveolar surgery.
