Abstract
Delirium is a common complication in acute stroke patients, occurring in 15-35% of all stroke unit admissions and is associated with prolonged hospital stay and a poor post-stroke prognosis. Managing delirium in acute stroke patients necessitates an intensive and multiprofessional therapeutic approach, placing a significant burden on healthcare staff. However, dedicated practical recommendations for delirium management developed for the population of acute stroke patients are lacking. For this purpose, the Austrian Stroke Society, in cooperation with the Austrian Society of Neurology, the Austrian Society of Neurorehabilitation, and the Austrian Society of Psychiatry, Psychotherapy, and Psychosomatics has formulated an evidence-based position paper addressing the management of delirium in acute stroke patients. The paper outlines practical recommendations on the three pillars of care in stroke patients with delirium: (a) Key aspects of delirium prevention including stroke-specific delirium risk factors and delirium prediction scores are described. Moreover, a non-pharmacological delirium prevention bundle is presented. (b) The paper provides recommendations on timing and frequency of delirium screening to ensure early diagnosis of delirium in acute stroke patients. Moreover, it reports on the use of different delirium screening tools in stroke populations. (c) An overview of non-pharmacological and pharmacological treatment strategies in patients with delirium and acute stroke is presented and summarized as key recommendation statements.

Abstract
OBJECTIVES Postoperative delirium is an acute neurocognitive complication that can have adverse effects on outcomes of geriatric patients after undergoing hip fracture surgery. The objective of this study was to examine the efficacy of preoperative steroids in preventing postoperative delirium after hip fracture surgery. METHODS DATA SOURCES A systematic review and meta-analysis was performed using PubMed, SPORTDiscus, CINAHL, MEDLINE, and Web of Science from database inception until September 28, 2023. STUDY SELECTION Inclusion criteria were randomized controlled trials of patients who underwent surgical intervention for hip fracture, were examined for postoperative delirium, and used preoperative steroids. DATA EXTRACTION Data included the risk of postoperative delirium, postoperative all-cause infection, and postoperative hyperglycemia. Articles were graded via the Cochrane Collaboration's tool. DATA SYNTHESIS Statistical analysis included a random-effects binary model with relative risk, 95% confidence intervals along with a defined "number needed to treat" threshold (number needed to treat). RESULTS Four randomized controlled trials were included from 128 articles initially retrieved. Patients (n = 416; average age: 82.2 ± 2.2 years) underwent surgical intervention for hip fracture after receiving either preoperative steroids (n = 209) or control interventions (n = 207). There was a statistically significant decrease in the incidence of postoperative delirium among patients who received preoperative steroids (12.9%; 27 cases) as compared with patients who received control interventions (26.7%; 55 cases) after hip fracture surgery ( P < 0.001; RR: 0.84). The absolute risk difference was 13.8%, and the number needed to treat was 7.2 patients. There was no statistically significant difference in the risk of postoperative all-cause infection among patients who received preoperative steroids as compared with patients who received normal saline as placebo after hip fracture surgery ( P = 0.850; RR: 0.96). CONCLUSIONS The utilization of preoperative steroids seems to decrease the risk of postoperative delirium after hip fracture surgery in elderly adults. Furthermore, this decreased risk of postoperative delirium was not associated with a significant increase in postoperative infection, indicating possible safety of preoperative steroid administration. LEVEL OF EVIDENCE Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Delirium and dementia are two frequent causes of cognitive impairment among older adults and have a distinct, complex and interconnected relationship. Delirium is an acute confusional state characterized by inattention, cognitive dysfunction and an altered level of consciousness, whereas dementia is an insidious, chronic and progressive loss of a previously acquired cognitive ability. People with dementia have a higher risk of developing delirium than the general population, and the occurrence of delirium is an independent risk factor for subsequent development of dementia. Furthermore, delirium in individuals with dementia can accelerate the trajectory of the underlying cognitive decline. Delirium prevention strategies can reduce the incidence of delirium and associated adverse outcomes, including falls and functional decline. Therefore, delirium might represent a modifiable risk factor for dementia, and interventions that prevent or minimize delirium might also reduce or prevent long-term cognitive impairment. Additionally, understanding the pathophysiology of delirium and the connection between delirium and dementia might ultimately lead to additional treatments for both conditions. In this Review, we explore mechanisms that might be common to both delirium and dementia by reviewing evidence on shared biomarkers, and we discuss the importance of delirium recognition and prevention in people with dementia. In this Review, Fong and Inouye explore mechanisms that might be common to both delirium and dementia. They present delirium as a possible modifiable risk factor for dementia and discuss the importance of delirium prevention strategies in reducing this risk. Delirium and dementia are frequent causes of cognitive impairment among older adults and have a distinct, complex and interconnected relationship. Delirium prevention strategies have been shown to reduce not only the incidence of delirium but also the incidence of adverse outcomes associated with delirium such as falls and functional decline. Adverse outcomes associated with delirium, such as the onset of dementia symptoms in individuals with preclinical dementia, and/or the acceleration of cognitive decline in individuals with dementia might also be delayed by the implementation of delirium prevention strategies. Evidence regarding the association of systemic inflammatory and neuroinflammatory biomarkers with delirium is variable, possibly as a result of co-occurring dementia pathology or disruption of the blood–brain barrier. Alzheimer disease pathology, even prior to the onset of symptoms, might have an effect on delirium risk, with potential mechanisms including neuroinflammation and gene–protein interactions with the APOE ε4 allele. Novel strategies, including proteomics, multi-omics, neuroimaging, transcranial magnetic stimulation and EEG, are beginning to reveal how changes in cerebral blood flow, spectral power and connectivity can be associated with delirium; further work is needed to expand these findings to patients with delirium superimposed upon dementia.

Acta Psychiatr Scand 2022; 147:430-459.

Abstract
OBJECTIVE Little is known about the economic value of clinical interventions for delirium. This review aims to synthesise and appraise available economic evidence, including resource use, costs, and cost-effectiveness of interventions for reducing, preventing, and treating delirium. METHODS Systematic review of published and grey literature on full and partial economic evaluations. Study quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS). RESULTS Fourteen economic evaluations (43% full, 57% partial) across nine multicomponent and nonpharmacological intervention types met inclusion criteria. The intervention costs ranged between US$386 and $553 per person in inpatient settings. Multicomponent delirium prevention intervention and the Hospital Elder Life Program (HELP) reported statistically significant cost savings or cost offsets somewhere else in the health system. Cost savings related to inpatient, outpatient, and out-of-pocket costs ranged between $194 and $6022 per person. The average CHEERS score was 74% (±SD 10%). CONCLUSION Evidence on a joint distribution of costs and outcomes of delirium interventions was limited, varied and of generally low quality. Directed expansion of health economics towards the evaluation of delirium care is necessary to ensure effective implementation that meets patients' needs and is cost-effective in achieving similar or better outcomes for the same or lower cost.

Abstract
OBJECTIVES It is not known whether using propofol total intravenous anaesthesia (TIVA) to reduce incidence of postoperative nausea and vomiting (PONV) is cost-effective. We assessed the economic impact of propofol TIVA versus inhalational anesthesia in adult patients for ambulatory and inpatient procedures relevant to the US healthcare system. METHODS Two models simulate individual patient pathways through inpatient and ambulatory surgery with propofol TIVA or inhalational anesthesia with economic inputs from studies on adult surgical US patients. Efficacy inputs were obtained from a meta-analysis of randomized controlled trials. Probabilistic and deterministic sensitivity analyses assessed the robustness of the model estimates. RESULTS Lower PONV rate, shorter stay in the post-anesthesia care unit, and reduced need for rescue antiemetics offset the higher costs for anesthetics, analgesics, and muscle relaxants with propofol TIVA and reduced cost by 11.41 ± 10.73 USD per patient in the inpatient model and 11.25 ± 9.81 USD in the ambulatory patient model. Sensitivity analyses demonstrated strong robustness of the results. CONCLUSIONS Maintenance of general anesthesia with propofol was cost-saving compared to inhalational anesthesia in both inpatient and ambulatory surgical settings in the United States. These economic results support current guideline recommendations, which endorse propofol TIVA to reduce PONV risk and enhance postoperative recovery.

Abstract
BACKGROUND Interprofessional geriatric consultation teams and multicomponent interventions are established models for delirium care. They are combined in interprofessional consultative delirium team interventions; however, insight into this novel approach is lacking. OBJECTIVE To describe the effectiveness and core components of consultation-based interventions for delirium. METHOD Ovid MEDLINE, EMBASE, PsycINFO, CINAHL, and ProQuest. Data on core intervention components, outcomes, facilitators, and barriers were extracted. RESULTS 10 studies were included. Core intervention components were systematic delirium screening, ongoing consultation, implementation of non-pharmacologic and pharmacological interventions, and staff education. Of the included studies, 1/6 found a significant reduction in delirium incidence, 1/2 a reduction in delirium duration, and 2/3 found a reduction in falls. Facilitators and barriers to implementation were discussed. CONCLUSION There was consistency in team structure and core components, however intervention operationalization and effectiveness varied widely. There is some evidence that this model is effective for reducing delirium and its sequelae.

Abstract
BACKGROUND Delirium is a common and serious neuropsychiatric syndrome, usually triggered by illness or drugs. It remains underdetected. One reason for this is a lack of brief, pragmatic assessment tools. The 4 'A's test (Arousal, Attention, Abbreviated Mental Test - 4, Acute change) (4AT) is a screening tool designed for routine use. This project evaluated its usability, diagnostic accuracy and cost. METHODS Phase 1 - the usability of the 4AT in routine practice was measured with two surveys and two qualitative studies of health-care professionals, and a review of current clinical use of the 4AT as well as its presence in guidelines and reports. Phase 2 - the 4AT's diagnostic accuracy was assessed in newly admitted acute medical patients aged ≥ 70 years. Its performance was compared with that of the Confusion Assessment Method (CAM; a longer screening tool). The performance of individual 4AT test items was related to cognitive status, length of stay, new institutionalisation, mortality at 12 weeks and outcomes. The method used was a prospective, double-blind diagnostic test accuracy study in emergency departments or in acute general medical wards in three UK sites. Each patient underwent a reference standard delirium assessment and was also randomised to receive an assessment with either the 4AT (n = 421) or the CAM (n = 420). A health economics analysis was also conducted. RESULTS Phase 1 found evidence that delirium awareness is increasing, but also that there is a need for education on delirium in general and on the 4AT in particular. Most users reported that the 4AT was useful, and it was in widespread use both in the UK and beyond. No changes to the 4AT were considered necessary. Phase 2 involved 785 individuals who had data for analysis; their mean age was 81.4 (standard deviation 6.4) years, 45% were male, 99% were white and 9% had a known dementia diagnosis. The 4AT (n = 392) had an area under the receiver operating characteristic curve of 0.90. A positive 4AT score (> 3) had a specificity of 95% [95% confidence interval (CI) 92% to 97%] and a sensitivity of 76% (95% CI 61% to 87%) for reference standard delirium. The CAM (n = 382) had a specificity of 100% (95% CI 98% to 100%) and a sensitivity of 40% (95% CI 26% to 57%) in the subset of participants whom it was possible to assess using this. Patients with positive 4AT scores had longer lengths of stay (median 5 days, interquartile range 2.0-14.0 days) than did those with negative 4AT scores (median 2 days, interquartile range 1.0-6.0 days), and they had a higher 12-week mortality rate (16.1% and 9.2%, respectively). The estimated 12-week costs of an initial inpatient stay for patients with delirium were more than double the costs of an inpatient stay for patients without delirium (e.g. in Scotland, £7559, 95% CI £7362 to £7755, vs. £4215, 95% CI £4175 to £4254). The estimated cost of false-positive cases was £4653, of false-negative cases was £8956, and of a missed diagnosis was £2067. LIMITATIONS Patients were aged ≥ 70 years and were assessed soon after they were admitted, limiting generalisability. The treatment of patients in accordance with reference standard diagnosis limited the ability to assess comparative cost-effectiveness. CONCLUSIONS These findings support the use of the 4AT as a rapid delirium assessment instrument. The 4AT has acceptable diagnostic accuracy for acute older patients aged > 70 years. FUTURE WORK Further research should address the real-world implementation of delirium assessment. The 4AT should be tested in other populations. TRIAL REGISTRATION Current Controlled Trials ISRCTN53388093. FUNDING This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 23, No. 40. See the NIHR Journals Library website for further project information. The funder specified that any new delirium assessment tool should be compared against the CAM, but had no other role in the study design or conduct of the study.

Abstract
INTRODUCTION Postoperative delirium (POD) is a common complication in elderly surgical patients. Patients undergoing hip fractures surgery who are often characterized by advanced age could be particularly prone to suffering POD. We performed a meta-analysis to assess the association between POD and mortality in elderly patients undergoing hip fractures surgery. This meta-analysis included twenty-one cohort studies, and the pooled outcomes demonstrated that approximated one-fourth of patients undergoing hipfracture surgery would develop POD, and delirium increased the mortality in these patients. METHODS We searched PubMed, Embase, Web of Science, and Scopus for studies that investigated the effect of POD on mortality in elderly patients undergoing hip fracture surgery. Two reviewers independently selected studies, assessed quality, and extracted data. Statistical analyses were performed by STATA 14.0 and RevMan 5.3. Risk ratios (RRs) with 95% confidence intervals (CIs) were derived using random or fixed-effects model. RESULTS Twenty-one cohort studies enrolling a total of 6288 patients were included, and the pooled prevalence (95% CI) of POD was 28% (23-34%). POD was associated with an increase in perioperative mortality (30-day or in-hospital mortality) [12 studies, 3123 patients, relative risk (RR) (95% CI) 2.79 (1.97-3.93)], 6-month mortality [6 studies, 1673 patients, 2.51 (1.99-3.16)], 1-year mortality [6 studies, 1896 patients, 1.98 (1.62-2.41)], and more than 1-year mortality [8 studies, 1926 patients, 2.06 (1.60-2.64)]. CONCLUSIONS Our meta-analysis demonstrated that approximated one-fourth of patients undergoing hip fracture surgery would develop POD, and delirium increased the short-term and long-term mortality in these patients.

Abstract
Perioperative interventions aimed at decreasing costs and improving outcomes have become increasingly popular in recent years. Anesthesiologists are often faced with a choice among different treatment strategies with little data available on the comparative cost-effectiveness. We performed a systematic review of the English language literature between 1980 and 2014 to identify cost-effectiveness analyses of anesthesiology and perioperative medicine interventions. We excluded interventions related to critical care or pediatric anesthesiology, and articles on interventions not normally ordered or performed by anesthesiologists. Of the >5000 cost-effectiveness analyses published to date, only 28 were applicable to anesthesiology and perioperative medicine and met inclusion criteria. Multidisciplinary interventions were the most cost-effective overall; 8 of 8 interventions were "dominant" (improved outcomes, reduced cost) or cost-effective, including accelerated, standardized perioperative recovery pathways, and perioperative delirium prevention bundles. Intraoperative measures were dominant in 3 of 5 cases, including spinal anesthesia for benign abdominal hysterectomy. With regard to prevention of perioperative infection, methicillin-resistant Staphylococcus aureus (MRSA) decolonization was dominant or cost-effective in 2 of 2 studies. Three studies assessing various antibiotic prophylaxis regimens had mixed results. Autologous blood donation was not found to be cost-effective in 5 of 7 studies, and intraoperative cell salvage therapy was also not cost-effective in 2 of 2 reports. Overall, there remains a paucity of cost-effectiveness literature in anesthesiology, particularly relating to intraoperative interventions and multidisciplinary perioperative interventions. Based on the available studies, multidisciplinary perioperative optimization interventions such as accelerated, standardized perioperative recovery pathways, and perioperative delirium prevention bundles tended to be most cost-effective. Our review demonstrates that there is a need for more rigorous cost-effective analyses in many areas of anesthesiology and that anesthesiologists should continue to lead collaborative, multidisciplinary efforts in perioperative medicine.

Abstract
PURPOSE This study is performed to identify risk factors for delirium in osteoporotic hip fractures and to evaluate the hospitalization cost and clinical outcomes of delirium in osteoporotic hip. METHODS A total of 221 patients with osteoporotic hip fractures were assessed for eligibility between 2010 and 2014. Among them, 37 patients with delirium were allocated into the delirium group (group D) and 37 patients without delirium were allocated into the non-delirium group (group ND) by matching demographic factors. Risk factors such as time between admission and operation, body mass index, American Society of Anesthesiologists status, cognitive impairment, preoperative urinary catheter, electrolyte imbalance, preoperative hemoglobin, polymedication (medications > 5), pneumonia, anesthesia time, operation time, estimated blood loss, and total amount of transfusion were evaluated for correlation with incidence of delirium. The hospitalization cost was evaluated, and clinical outcomes such as readmission, mortality, and activity level at 1-year follow-up were evaluated. RESULTS In multivariate analysis, polymedication ( p = 0.028) and preoperative indwelling urinary catheter insertion status ( p = 0.007) were related to the incidence of delirium in patients with osteoporotic hip fractures. Group D showed a significantly higher hospitalization cost compared to group ND. However, delirium did not have a significant effect on length of hospital stay, readmission rate, postoperative 1-year mortality, and activity level. CONCLUSIONS Polymedication and preoperative urinary catheter were related to perioperative delirium. In addition, delirium in osteoporotic hip fractures may not have a detrimental effect on clinical outcomes; however, hospitalization cost seemed to be increased due to delirium.

Abstract
Importance Delirium is defined as an acute disorder of attention and cognition. It is a common, serious, and often fatal condition among older patients. Although often underrecognized, delirium has serious adverse effects on the individual's function and quality of life, as well as broad societal effects with substantial health care costs. Objective To summarize the current state of the art in diagnosis and treatment of delirium and to highlight critical areas for future research to advance the field. Evidence Review Search of Ovid MEDLINE, Embase, and the Cochrane Library for the past 6 years, from January 1, 2011, until March 16, 2017, using a combination of controlled vocabulary and keyword terms. Since delirium is more prevalent in older adults, the focus was on studies in elderly populations; studies based solely in the intensive care unit (ICU) and non-English-language articles were excluded. Findings Of 127 articles included, 25 were clinical trials, 42 cohort studies, 5 systematic reviews and meta-analyses, and 55 were other categories. A total of 11 616 patients were represented in the treatment studies. Advances in diagnosis have included the development of brief screening tools with high sensitivity and specificity, such as the 3-Minute Diagnostic Assessment; 4 A's Test; and proxy-based measures such as the Family Confusion Assessment Method. Measures of severity, such as the Confusion Assessment Method-Severity Score, can aid in monitoring response to treatment, risk stratification, and assessing prognosis. Nonpharmacologic approaches focused on risk factors such as immobility, functional decline, visual or hearing impairment, dehydration, and sleep deprivation are effective for delirium prevention and also are recommended for delirium treatment. Current recommendations for pharmacologic treatment of delirium, based on recent reviews of the evidence, recommend reserving use of antipsychotics and other sedating medications for treatment of severe agitation that poses risk to patient or staff safety or threatens interruption of essential medical therapies. Conclusions and Relevance Advances in diagnosis can improve recognition and risk stratification of delirium. Prevention of delirium using nonpharmacologic approaches is documented to be effective, while pharmacologic prevention and treatment of delirium remains controversial.

Abstract
BACKGROUND AND PURPOSE Delirium is common after hip fracture. Previous work has shown that a simple delirium risk factor tool, the Delirium Elderly At Risk instrument (DEAR), has a high inter-rater reliability in this population. Little research has looked at the ability of risk factor screening tools to identify patients at high risk of pre-operative delirium. This study investigates the ability of the DEAR to identify patients at high risk of pre-operative delirium, as well as reporting its performance in a post-operative validation sample. Associations between delirium risk factors and pre-operative delirium are explored. METHODS This prospective cohort study took place on an orthopedic in-patient service at a University-affiliated tertiary care hospital. Patients aged 65 and older who were admitted for surgical repair of hip fracture (N = 283) were assessed pre-operatively for 5 delirium risk factors (cognitive impairment, sensory impairment, functional dependence, substance use, age) using the DEAR. Patients were assessed for delirium using the Mini-Mental State Examination and the Confusion Assessment Method pre-operatively and on post-operative days 1, 3 and 5. Characteristics of patients who developed delirium were compared with the characteristics of those who did not. RESULTS Delirium was present in 58% (95% CI = 52-63%) of patients pre-operatively and 42% (95% CI = 36-48%) post-operatively. Individually, sensory impairment (χ(2) = 21.7, p = .0001), functional dependence (χ(2) = 24.1, p = .0001), cognitive impairment (χ(2) = 55.5, p = .0001) and substance use (χ(2) = 7.5, p = .007) were significantly associated with pre-operative delirium, as was wait-time for surgery (t = 3.1, p = .003) and length of stay (t = 2.8, p =.03). In multivariate modeling, the strongest association with pre-operative delirium was cognitive impairment. CONCLUSIONS The DEAR, a simple, delirium risk factor screening tool, can be used to identify hip fracture patients at risk of both pre-operative and post-operative delirium, which may allow targeted implementation of delirium prevention strategies.
