Predictors of Social Frailty and Depression in Brazilian Patients With Chronic Kidney Disease: A Cross-Sectional Study
Abstract: 
BACKGROUND: Social frailty is linked to adverse health outcomes, including depression, especially in older and chronically ill individuals. This study aimed to assess the prevalence and associated factors of social frailty in Brazilian CKD patients undergoing hemodialysis or kidney transplantation and to examine its predictive role in the development of depressive symptoms. 
METHODS: This cross-sectional, correlational, and comparative study included 284 patients with CKD from São Paulo, Brazil. Data were collected using validated instruments: HALFT Social Frailty Scale, Patient Health Questionnaire-9 (PHQ-9), and Medical Outcomes Study Social Support Scale (MOS). Two multiple linear regression (MLR) models were used to assess predictors of social frailty and depressive symptoms, adjusting for sociodemographic and clinical variables. 
RESULTS: Social frailty was significantly more prevalent among HD patients (51.2%) compared to TX patients (24%). Social support was negatively associated with social frailty (β = -0.40; p < 0.001). Other predictors of greater social frailty included lower income (β = 0.51 for ≤ 1 minimum wage), number of medications (β = 0.11), and lower education (β = -0.13). In turn, social frailty was the strongest predictor of depressive symptoms (β = 0.60; p < 0.001). TX status and male sex were associated with lower depression scores. 
CONCLUSION: Social frailty is highly prevalent in CKD patients, particularly those undergoing HD, and strongly predicts depressive symptoms. Strategies to enhance social support and reduce socioeconomic vulnerability may help mitigate mental health burdens in this population.

Frailty in Focus: A Scoping Review of Frailty Instruments from the Kidney Disease Aging Research Collaborative
Abstract: 
BACKGROUND: Frailty is a multi-system syndrome of decreased physiologic reserve with high prevalence, early incidence, and prognostic significance in kidney disease. Apart from the Physical Frailty Phenotype (PFP), less is known regarding psychometric properties of other instruments. We critically appraise the validity and reliability of frailty instruments across the kidney disease continuum, acknowledge limitations, and highlight knowledge gaps. METHODS: Following PRISMA-ScR guidelines, we searched PubMed, EMBASE, Cochrane, CINAHL, Web of Science, ClinicalTrials.gov, and PsycInfo from website inception through 9/2024. Eligible studies applied a validated frailty instrument apart from the PFP to a kidney disease population. 
RESULTS: We identified 136 articles after screening 4,048 initial results. The most commonly cited instruments were the Clinical Frailty Scale (CFS; N=56), FRAIL Scale (N=30), and Edmonton Frail Scale (N=16). Most studies included adults receiving hemodialysis (N=85) and with chronic kidney disease (N=39). Median age ranges were 53–83 years. Most frailty instruments demonstrated predictive validity for mortality and hospitalizations. Concurrent validity was most frequently demonstrated between frailty and older age, female sex, greater comorbidities, and lower albumin. Seven studies reported reliability. While some instruments were feasible (CFS, FRAIL scale), their measurement could result in higher frailty prevalence compared to the PFP. Existing instruments do not capture the full spectrum of psychosocial and physiologic domains of frailty. 
CONCLUSIONS: The CFS demonstrates the strongest validity, apart from the PFP, although its use may result in higher measured frailty prevalence. Further research should test the feasibility of screening for frailty in clinical practice; the psychometric properties (i.e., responsiveness) of frailty instruments in younger adults, those with acute kidney injury, kidney transplant recipients, and those receiving conservative kidney management; and whether adding psychosocial and/or physiological markers improves frailty measurement validity. Addressing these gaps will facilitate wider frailty measurement in kidney disease research and aid adoption into practice.

Patient-reported outcome measures (proms) and frailty in kidney transplant candidates
Abstract: 
BACKGROUND AND OBJECTIVE: Patient-reported outcomes (PROMs) are key tools for advancing patient-centered clinical practice, with proven benefits for health outcomes. Their application has been extended to different chronic diseases, but there are few studies involving patients with chronic kidney disease (CKD), a population that is aging and frail. The aim of this study was to assess the relationship between frailty and self-reported health-related quality of life in patients with advanced CKD who are eligible for kidney transplantation (KT). MATERIALS AND METHODS: KT candidates who were evaluated in the outpatient clinic were included in the study. The PROMIS-29® and PROMIS-Global Health® questionnaires were administered, and T-scores were calculated for each domain. Frailty was assessed using the Fried scale, categorizing participants as frail/pre-frail if FRIED > 0. Sociodemographic and clinical variables were also collected. 
RESULTS: 139 KT candidates were included in the study: 32% were women, the mean age was 63.5 years, 43.9% were on dialysis, and 64.5% were frail. 71.2% responded to the administered PROMIS. Overall, KT candidates reported their mental health as good (48 ± 7.4) and their physical health as fair (42.8 ± 7.3). T-scores for anxiety, fatigue, social functioning, sleep disturbance, pain, and depression were within the normal range compared to the general population. When comparing frail with robust patients, only the physical domain of PROMIS-Global Health® and physical function of PROMIS-29® were worse in the frail group. No differences were found in the other domains. 
CONCLUSIONS: Frail kidney transplant candidates report worse physical function when assessed using PROMs tools. The systematic implementation of PROMs might help to implement strategies to optimize access to the waiting list, improve postKT outcomes, and enhance overall patient care.

Risk Prediction Models for Frailty in Adult Maintenance Haemodialysis Patients: A Systematic Review and Methodological Appraisal
Abstract: 
BACKGROUND: Frailty affects over 35% of maintenance haemodialysis (MHD) patients globally-2-3 times higher than the general elderly-and is strongly linked to higher mortality, hospitalisation, and functional decline. Despite its clinical impact, frailty is often underdiagnosed in dialysis settings due to inconsistent assessments and limited resources. Existing prediction models vary widely in predictors and methods, requiring systematic review to guide clinical use and improve risk-stratified care. 
AIM: To systematically identify, describe, and evaluate the existing risk prediction models for frailty in patients undergoing MHD. 
DESIGN: Systematic review and Methodological appraisal. 
DATA SOURCES: A comprehensive search was conducted across multiple databases-PubMed, Web of Science Core Collection, Embase, Cochrane Library, CINAHL, China Biomedical Literature Database (CBM), Wanfang Database, VIP Database-covering studies up to November 1, 2024. 
REVIEW METHODS: Two researchers independently conducted literature searches, screening, and data extraction. They used the Prediction Model Risk of Bias Assessment Tool (PROBAST) to evaluate the risk of bias and the applicability of the included models. RESULTS: Fifteen studies (21 models) were analysed, with sample sizes 141-786 and frailty incidence 11.00%-59.57%. Model AUCs ranged 0.720-0.998 (potential overfitting at extreme values). Key predictors included age, serum albumin, gender, Charlson comorbidity index, and activities of daily living scores. Methodological appraisal using PROBAST revealed moderate applicability but high bias risks: 53% of studies used retrospective designs, 95% lacked external validation, and limitations included small samples, non-standard variable selection, and inadequate handling of missing data. 
CONCLUSION: While models demonstrate initial predictive utility, widespread bias and developmental-stage limitations hinder clinical application. Future research must prioritise TRIPOD-guided model development, emphasising large prospective cohorts, rigorous validation, and transparent reporting to enhance reliability and clinical utility in frailty risk stratification for MHD patients.

Frailty and pre-frailty prevalence in community-dwelling elderly with multimorbidity: A systematic review and meta-analysis
Abstract: 
BACKGROUND: The relationship between frailty/pre-frailty, and multimorbidity in the elderly is recognized, but specific prevalence among community-dwelling elderly with multimorbidity is unclear. This study aims to determine these rates, analyze subgroup, and identify sources of heterogeneity to bolster evidence-based interventions and health policies. 
METHODS: We searched nine databases from inception to November 16, 2023, for cross-sectional and cohort studies on community-dwelling elderly with multimorbidity. Data were extracted to calculate the prevalence of frailty and pre-frailty. Study quality was assessed using AHRQ and NOS tools. 
RESULTS: Fifteen studies encompassing 9,683 participants with multimorbidity were analyzed. The pooled prevalence of frailty and pre-frailty was 18.1 % and 48.9 %, respectively. Age-stratified analyses found 17 % frailty and 58.4 % pre-frailty in the 70-74 age group, and 16.7 % and 54.2 % in those above 75 years. Cross-sectional studies showed 18.8 % frailty and 48.1 % pre-frailty, while cohort studies showed 18.1 % and 50.5 %, respectively. Asia had higher rates (22.7 % frailty, 43.5 % pre-frailty) than the Americas (9.9 % frailty, 56.3 % pre-frailty). By sample size, frailty prevalence was 21.3 % (<500), 9.1 % (500-999), and 17.9 % (≥1000), with pre-frailty at 51.1 %, 45.6 %, and 47.7 %. The FP method yielded higher prevalence estimates (17.7 % frailty, 51.6 % pre-frailty) than the FS method (9.5 % frailty, 39.2 % pre-frailty). 
CONCLUSION: This study provides insights into the prevalence of frailty and pre-frailty among community-dwelling elderly with multimorbidity. Variations in prevalence rates may be attributed to differences in sample size and measurement tools, which also contribute to heterogeneity observed across subgroups.

A Mixed Methods Study of Risk Factors for Frailty in Peritoneal Dialysis Patients
Abstract: 
OBJECTIVES: This study uses a convergent mixed methods approach to investigate the frailty phenotypes and risk factors in peritoneal dialysis (PD) patients. DESIGN: A cross-sectional mixed methods research study was employed. 
METHODS: This study follows the MMR-RHS reporting guidelines. From November 2023 to August 2024, 213 patients were recruited from the PD centre of a tertiary hospital in Chongqing, China. Quantitative data were collected using a general information questionnaire and standardised scales, including Fried Frailty Phenotype (FFP), Charlson Comorbidity Index (CCI), Mini Nutritional Assessment-Short Form (MNA-SF), Montreal Cognitive Assessment (MoCA) and Hospital Anxiety and Depression Scale (HADS). Concurrently, 19 PD patients in pre-frail or frail states participated in semi-structured interviews. The quantitative and qualitative findings were then integrated for analysis. 
RESULTS: Amongst the 213 PD patients, 46.5% were non-frail, 41.3% were pre-frail and 12.2% were frail. Integrated analysis indicated that fatigue and low muscle strength were the primary frailty phenotypes amongst the patients. Age, sedentary behaviour, comorbidities, nutritional status, cognitive function, polypharmacy, psychological state and social connections were identified as risk factors for frailty in this patient population. 
CONCLUSION: Many factors influence the frailty of PD patients. Future research should further explore the complex interactions amongst these factors and effective modulation strategies to mitigate the frailty progression. Incorporating the patients' perspectives in designing comprehensive intervention programmes will help identify key challenges and focal points for intervention. 
IMPACT: This study identifies risk factors for frailty in PD patients, offering healthcare professionals a basis for designing targeted interventions. These factors encompass multiple dimensions, indicating the need for multidisciplinary collaboration in managing frailty. 
PATIENT CONTRIBUTION: The PD patients in this study provided valuable quantitative data and shared their frailty experiences, enhancing the research conclusions' practical value.

Frailty risk prediction models in maintenance hemodialysis patients: a systematic review and meta-analysis of model performance and methodological quality
Abstract: 
BACKGROUND: Frailty affects outcomes in maintenance hemodialysis (MHD) patients, highlighting the need for reliable predictive tools. Despite the rise of predictive models, the clinical validity and scientific quality of these models remain unknown. 
OBJECTIVE: The purpose of this systematic review is to assess the clinical usefulness, predictive accuracy, and methodological quality of the current frailty risk prediction models in patients with MHD. 
METHODS: Databases including PubMed, Embase, Cochrane Library, CNKI, and others were comprehensively searched until August 2024. Studies that created or validated frailty risk prediction models for adult MHD patients were considered. The Newcastle-Ottawa Scale (NOS) and PROBAST were used to measure quality. The meta-analysis examined common predictive factors. 
RESULTS: Twelve of the 824 papers that reported 14 prediction models satisfied the inclusion criteria. The most common method was logistic regression. Frailty prevalence ranged from 17.2% to 79.2%. Age, albumin, depression, and dietary condition were among the variables that were most often found. Model performance varied considerably, with area under the curve (AUC) ranging from 0.72 to 0.998. All studies had significant methodological deficiencies. CONCLUSIONS: Existing frailty risk prediction models demonstrate potential utility but currently suffer from significant methodological flaws and limited external validation, impairing their clinical applicability. Future models should emphasize rigorous study design, standardized statistical methods, and robust external validation. Clinicians should cautiously interpret existing models while focusing on critical predictors such as age, albumin, depression, and nutrition for frailty management in MHD patients.

Effects of Exercise on Sarcopenia and Frailty in Haemodialysis Patients: A Systematic Review 
Abstract: 
Background and Objectives: Chronic kidney disease is characterized by the progressive loss of functioning nephrons due to structural and functional alterations in the kidneys. It is clinically defined through the presence of a glomerular filtration rate below 60 mL/min/1.73 m(2) or persistent kidney damage lasting at least three months. Patients undergoing haemodialysis frequently present with sarcopenia and frailty. The aim of this study was to evaluate the effects of intradialytic exercise on sarcopenia and frailty in individuals with chronic kidney disease. Materials and Methods: A systematic review was conducted in accordance with PRISMA guidelines. Electronic searches were executed in PubMed, PEDro, Scopus, and Dialnet. Eligible studies included adults (≥18 years) on haemodialysis who engaged in exercise interventions compared with passive control groups. Exclusion criteria included any conditions conflicting with the inclusion criteria, systematic reviews, study protocols, and articles not meeting the PICO framework or contradictory to the inclusion criteria. Outcomes of interest were sarcopenia and frailty, assessed through measures of physical function and muscle strength. Methodological quality was appraised using the PEDro scale, and risk of bias was evaluated with the Cochrane Risk of Bias tool. 
Results: Fifteen studies met the inclusion criteria. Most interventions consisted of aerobic training, resistance training, or combined exercise programs. Across studies, exercise interventions consistently improved physical function and muscle strength, although no significant effects on body composition were observed. 
Conclusions: This systematic review provides evidence that intradialytic exercise may produce clinically relevant improvements in sarcopenia by enhancing muscle strength and functional performance, as measured by tests such as the sitting-to-standing test. These results suggest that intradialytic exercise could be beneficial for patients with chronic kidney disease.

Comparison of diagnostic characteristics of four frailty screening tools in maintenance hemodialysis patients
Abstract: 
BACKGROUND: A variety of frailty assessment tools are used internationally, and there is variation in the selection of frailty assessment tools for patients undergoing maintenance hemodialysis (MHD). The most suitable tool for this population remains unclear. This study compared the validity of four frailty assessment tools-the Fried Phenotype, FRAIL Scale, Clinical Frailty Scale (CFS), and Tilburg Frailty Index (T)-among MHD patients. The aim is to provide a reference for healthcare professionals selecting appropriate tools. 
METHODS: A convenience sample of 385 patients undergoing maintenance hemodialysis at two hemodialysis centers in Sichuan, China, from January to June 2025 was selected as the study population. All patients were assessed for frailty severity using four instruments. To minimize inclusion bias, the "leave-one-out" composite index (CI) was employed as the reference standard. Kappa statistics and McNemar's test were used to evaluate agreement between each tool and its corresponding CI. Diagnostic performance was assessed using receiver operating characteristic (ROC) curves, area under the curve (AUC), sensitivity, specicity, positive predictive value (PPV), negative predictive value (NPV), and accuracy. Decision curve analysis (DCA) evaluated clinical utility. 
RESULTS: The Fried Phenotype demonstrated the strongest agreement with its CI (Kappa = 0.789, P < 0.001), indicating excellent concordance and no signicant marginal heterogeneity (McNemar's P = 1.000). The CFS also showed good agreement with its CI (Kappa = 0.716, P < 0.001) without signicant marginal heterogeneity (McNemar's P = 0.074). In contrast, while the FRAIL and T showed moderate agreement with their respective CIs (Kappa = 0.705 and 0.537; both P < 0.001), McNemar's test indicated signicant marginal heterogeneity for both (P < 0.001). The AUC was highest for the Fried Phenotype (0.90), followed by CFS (0.85), T (0.84), and FRAIL (0.82). The Fried Phenotype achieved the best balance between sensitivity (93%) and specicity (86%). Decision curve analysis conrmed its superior net benet across most clinical threshold probabilities. 
CONCLUSION: The Fried Phenotype demonstrated the highest validity and diagnostic accuracy for frailty screening in MHD patients when benchmarked against a robust "leave-one-out" composite standard. The CFS also performed well with good agreement and discriminative ability. The FRAIL scale showed high sensitivity but lower specicity, while the T exhibited high specicity but poor sensitivity. Tool selection should be guided by clinical purpose-whether for screening, conrmation, or balanced assessment-to optimize frailty management in MHD patients and improve clinical outcomes.

Cognitive Frailty and Its Risk Factors Among Patients With Chronic Kidney Disease Receiving Hemodialysis: A Cross-Sectional Study
Abstract: Cognitive frailty can lead to an impaired functional capacity and a poor quality of life, especially in patients on hemodialysis. This study aimed to investigate cognitive frailty and its risk factors in patients with chronic kidney disease (CKD) receiving hemodialysis. A cross-sectional study was conducted between April and June 2021 involving 220 patients with CKD receiving hemodialysis at a hospital-based hemodialysis center in northern Taiwan. Data were collected using a structured survey covering demographics, cognitive function, physical frailty, depressive symptoms, physical activity, and nutritional status. Univariate and multivariate logistic regression models were used to identify risk factors for cognitive frailty. In total, 220 patients were recruited. Prevalences of cognitive impairment, physical frailty, depressive symptoms, and cognitive frailty were 46.8%, 10.0%, 52.3%, and 9%, respectively. Univariate and multivariate logistic regression analyses, adjusted for age, sex, and years of hemodialysis, identified malnutrition (aOR = 12.405; 95% CI = 3.29-46.81) and physical inactivity (aOR = 89.445; 95% CI = 5.87-1363.93) as significant risk factors for cognitive frailty. The study suggests the need for strategies to enhance physical activity and nutritional status to prevent cognitive frailty in patients with CKD receiving hemodialysis.

Multidimensional Determinants of Frailty in Haemodialysis Patients: The Overlooked Roles of Depression and Cognitive Function
Abstract: 
AIM: This study aims to examine the level of frailty in patients undergoing haemodialysis treatment and investigate the effects of sociodemographic, psychological and clinical variables on frailty. 
METHOD: A cross-sectional and correlational research design was employed with 386 haemodialysis patients over the age of 50. Data were collected using the Edmonton Frail Scale, Beck Depression Inventory, Standardized Mini-Mental Test and Eysenck Personality Questionnaire. 
RESULTS: The study revealed that 48.4% of haemodialysis patients fell into the 'apparently frail' category, and frailty levels were significantly associated with age, depression and cognitive functions (p < 0.05). However, no significant effect of gender, marital status, educational level, chronic diseases or personality traits on frailty was identified. CONCLUSIONS: Most haemodialysis patients were found to be apparently frail, with frailty levels increasing with age. Furthermore, frailty was linked to higher levels of depressive symptoms and lower cognitive function. Evaluating depression and cognitive function is crucial for alleviating frailty symptoms and improving quality of life.

Prevalence and Influence Factors of Cognitive Frailty in the Older Adult Patients Undergoing Maintenance Haemodialysis: A Multi-Centre Cross-Sectional Study
Abstract: 
AIMS: To examine the prevalence of factors of cognitive frailty in patients undergoing maintenance haemodialysis (MHD). 
DESIGN: A cross-sectional study. 
METHODS: From September 2023 to January 2024, 1023 patients undergoing MHD were recruited from 11 hospitals in Chengdu, China, using convenience sampling. The participants' sociodemographic and lifestyle factors, health information and laboratory indicators were assessed using a general information questionnaire. Cognitive frailty was assessed using the Fried Frailty Phenotype and Montreal Cognitive Assessment Scales. Multivariate logistic regression was used to examine the associations between cognitive frailty and sociodemographic and clinical characteristics. Independent variables for the multivariate logistic regression model encompassing age, sex, educational level, marital status, visual impairment, hearing impairment, falls within a year, depression, weight, height, Malnutrition-inflammation score and serum albumin, sodium, phosphorus, total cholesterol and creatinine levels. 
RESULTS: Among 1023 participants with a mean age of 69.52 years, 300 (29.3%) had cognitive frailty, with a predominance of older patients. Regression analysis showed that advanced age, low literacy and low serum creatinine, sodium and total cholesterol levels were positively correlated with cognitive frailty. Furthermore, 17.1% of the participants experienced depression, a risk factor for cognitive frailty, and malnutrition was an independent risk factor for cognitive frailty. 
CONCLUSION: Older adult patients undergoing (MHD) are at an increased risk of developing cognitive frailty. The aetiology of cognitive frailty in this cohort was multifactorial. Targeted interventions should be designed and implemented based on these factors, prioritising nutritional guidance and mood management to prevent or reverse cognitive frailty. REPORTING METHOD: The study adhered to the STROBE checklist. 
IMPACT: Older adult patients undergoing MHD are at increased risk of developing cognitive frailty. Cognitive frailty screening must be incorporated into the routine assessment of older patients undergoing MHD.

Frailty and Outcomes in Elderly ICU Patients: Insights from a Portuguese Cohort
Abstract: 
Background: Frailty is a key determinant of outcomes in critically ill elderly patients, but data from Portugal remain limited. To our knowledge, this is the first study to examine the prevalence and prognostic impact of frailty among elderly ICU patients in a Portuguese hospital setting. 
Objective: To determine the prevalence of frailty among elderly patients admitted to an intensive care unit (ICU) in southern Portugal and to examine its crude associations with illness severity, organ support, and mortality outcomes. 
Methods: We conducted a retrospective cohort study including 125 patients aged ≥ 65 years admitted to the polyvalent ICU of Hospital de Faro over the last six months of 2024. Data included demographics, comorbidities, Charlson Comorbidity Index (CCI), severity scores (SOFA, SAPS II, APACHE II), and frailty status assessed by the Clinical Frailty Scale (CFS). Outcomes were the need for organ support, ICU and hospital mortality, and length of stay. Results: Frailty (CFS ≥ 5) was identified in 30.4% of patients. Frail patients were older, had higher comorbidity burden (CCI), and presented with significantly higher severity scores at admission. They also required more invasive support, including vasopressors and invasive mechanical ventilation, while acute kidney injury (AKI) requiring renal replacement therapy (RRT) was similar between groups. ICU mortality was significantly higher among frail patients (50.0% vs. 31.0%), as was hospital mortality (76.3% vs. 33.3%). Length of ICU stay did not differ, although frail patients tended to have longer hospitalizations overall. 
Conclusions: Frailty was highly prevalent and strongly associated with increased severity, greater need for organ support, and higher mortality. Routine frailty assessment at ICU admission may enhance prognostic accuracy and support patient-centered decision-making.

Falls, Frailty and Quality of Life Among Individuals on a Regular Haemodialysis Programme: Implications for Rehabilitation Nursing
Abstract: 
BACKGROUND: Chronic kidney disease and haemodialysis treatment are associated with physiological and functional alterations that compromise postural stability, favouring frailty and the risk of falls. These conditions directly affect the quality of life and autonomy of people undergoing haemodialysis, constituting an important challenge for rehabilitation nursing. In this sense, the aim of this study was to analyse the relationship between falls, frailty and quality of life in people with chronic kidney disease on a regular haemodialysis programme, identifying implications for rehabilitation nursing care. 
METHODS: This was a quantitative, observational and cross-sectional study conducted with 62 participants from a haemodialysis unit in northern Portugal. The Tilburg Frailty Indicator and the Kidney Disease Quality of Life Instrument (KDQOL-SF™ 1.3) were applied. Statistical analysis used parametric and non-parametric tests, considering a significance level of p < 0.05. 
RESULTS: The prevalence of falls in the year preceding the data collection was 32.2%, and the prevalence of frailty was 40.3%. A significant association was found between frailty and falls (p = 0.038) and between sex and falls (p = 0.002). The dimensions Symptoms/problems and Effects of kidney disease on daily life showed lower scores among participants with falls (p < 0.001). 
CONCLUSIONS: Frailty and poorer illness perception were associated with the occurrence of falls and with lower quality of life. Comprehensive assessment and the implementation of rehabilitation programmes led by specialist nurses in rehabilitation nursing are essential to promote functionality, safety and autonomy in people undergoing haemodialysis.

The Effect of Frailty on Quality of Life in Older Patients Receiving Hemodialysis and Associations With Fear of Falling
Abstract: 
PURPOSE: This study investigated the effect of frailty and avoidance behavior due to fear of falling on the quality of life in older patients receiving hemodialysis treatment. 
METHODS: This study is cross-sectional and descriptive. The study was conducted between January 2 and 31, 2022, with 154 individuals aged 65 years and over receiving treatment in dialysis centers. The study data were collected using the Patient Information Form, Edmonton Frail Scale, Fear of Falling Avoidance-Behavior Questionnaire, and Quality of Life Scale (SF-12). 
RESULTS: The Mean Edmonton Frail Scale score was found to be 8.7 ± 3.36, the mean Fear of Falling Avoidance-Behavior Questionnaire score was found to be 33.17 ± 9.11, the mean SF-12 physical component score was found to be 34.32 ± 8.51, and the mean mental component score was seen as 41.77 ± 8.35. The Fear of Falling Avoidance-Behavior Questionnaire was an associated factor in the effect of the Edmonton Frail Scale on quality of life. It strengthened the negative impact of the Edmonton Frail Scale on quality of life. The predictive effect of these two variables in explaining quality of life was 59.3%. 
CONCLUSION: It was found that the participants had moderate levels of frailty, moderate levels of activity limitation, and participation restriction due to fear of falling, and low levels of physical and mental quality of life. It was determined that frailty had a direct impact on quality of life. Also, the indirect effect of frailty on quality of life was determined through the role of avoidance behavior due to fear of falling.

Quality of life experience in physically frail people on renal dialysis: A qualitative meta-synthesis on the difficulties and resources for better health care
Abstract: 
OBJECTIVE: This study aimed to summarize the quality of life experiences of individuals with physical frailty undergoing hemodialysis or peritoneal dialysis and to identify the difficulties and resources that enable better person-centered health care. 
METHODS: The study described is a qualitative meta-synthesis literature review. The search was performed in databases such as CINAHL, Scopus, PubMed, Web of Science, the Cochrane Library, and Cuiden Plus through Medical Subject Headings and free terms. Qualitative and mixed studies were included on individuals undergoing hemodialysis or peritoneal dialysis, 18 years of age or older, published in English or Spanish, between January 2013 and January 2024. The Mixed Methods Appraisal Tool was used to assess the methodological quality. The information was analyzed and coded through a socioecological model and the social determinants of health. 
RESULTS: Fourteen qualitative and two mixed articles were selected. A total of 256 individuals participated in the study. Seventeen themes and 25 sub-themes were identified and grouped into two blocks (difficulties and resources). The difficulties that stood out were a low tolerance for activities of daily living and physical activity, loss of self-control over life and social roles, and lack of community and public resources. As for the resources, the following was found: the positive meaning of dialysis, the safety offered by close individuals and the healthcare team, the activation of specific programs, and person-centered policies. 
CONCLUSIONS: The analysis and interpretation of the identified difficulties and resources revealed key elements to consider when designing and implementing health programs for individuals undergoing dialysis. Future research should explore these dimensions in diverse cultural and geographical contexts to enhance generalizability and support health equity.

Prevalence and risk factors of falls in people on hemodialysis: a systematic review and meta-analysis
Abstract: 
OBJECTIVES: This study aims to systematically quantify the prevalence of falls in people on hemodialysis and to assess risk factors associated with falls by synthesizing emerging best evidence. 
METHODS: A comprehensive search was conducted across ten databases from their inception to February 27, 2025. The research team independently conducted study selection, quality assessments, data extraction, and analyses of all included studies. Meta-analysis was performed using random-effects and fixed-effects models. The PRISMA guidelines were used to report the systematic review and meta-analysis. 
RESULTS: A total of 31 studies, comprising 191,800 individuals, were included in the analysis. The pooled prevalence of falls in people on hemodialysis was 27.1%. The meta-analysis of risk factors included 19 studies. After controlling for confounding variables, 12 risk factors were associated with falls, including older age, female gender, longer dialysis duration, diabetes mellitus, peripheral vascular disease, paralysis, antidepressant use, frailty, use of walking aids, malnutrition, intradialytic hypotension, and low hemoglobin levels. 
CONCLUSIONS: This study provides an updated, evidence-based assessment of the prevalence and risk factors of falls in people on hemodialysis, confirming their multifactorial etiology. Screening and interventions should be implemented promptly to mitigate the adverse outcomes of falls in people on hemodialysis.

  • The term, frailty, had unclear meaning for most participants but was commonly explained as weakness, dependence, and unmodifiable.
  • Knowledge of frailty assessment tools and the evidence to support their prognostic utility was low among clinicians.
  • Though patients and caregivers saw value in discussing frailty, the label of frailty was often viewed as pejorative.
Background: Frailty is highly prevalent among individuals with kidney failure and independently associated with poor health outcomes. Identifying and managing frailty can inform prognosis and care but stakeholders' understanding of frailty and their perspectives on how to detect and manage it in routine kidney care are unknown.
Methods: We recruited participants from four Canadian kidney programs in Alberta, Manitoba, and Nova Scotia from January 2021 to June 2023. We conducted focus groups and semistructured interviews with patients (50 years or older with dialysis-dependent or nondependent kidney failure), caregivers, allied health care professionals, and nephrologists. We used qualitative description and inductive thematic analysis to describe their perspectives.
Results: Ninety-one people participated: patients (N=31), caregivers (N=8), kidney allied health care professionals (N=38), and nephrologists (N=14). We identified three themes, each with subthemes: (1) What is frailty? All groups expressed uncertainty, but frailty was commonly described as physical, visible, inevitable, and fixed; (2) discussing frailty: the value of knowing what to expect with frailty, and frailty as a difficult topic to discuss; (3) frailty assessment and management: skepticism from patients and caregivers that frailty is measurable; support from clinicians for a systematic approach to identifying frailty but a lack of knowledge on multidisciplinary roles and potential interventions. For all groups, having actionable solutions after identifying frailty was key for acceptability and successful implementation.
Conclusions: Education on the nature and potentially modifiable aspects of frailty as well as the scope and potential benefits of frailty interventions is necessary for successful implementation of frailty detection and management in kidney care.

The Relationship Between Xerostomia, Nutrition, and Frailty in Older Patients Undergoing Hemodialysis
Abstract: Older adults receiving hemodialysis are at increased risk for xerostomia, poor nutritional status, and frailty, all of which significantly impact clinical outcomes and quality of life. This cross-sectional study examined interrelationships among xerostomia, nutrition, and frailty in patients aged 60 and older undergoing maintenance hemodialysis. Conducted between October 2022 and June 2023 in five dialysis centers, the study included 176 participants on hemodialysis for at least 3 months. Data were collected through face-to-face interviews using validated instruments: the Short Xerostomia Inventory, Mini Nutritional Assessment-Short Form, and Edmonton Frailty Scale. Pearson's correlation and path analysis using the Maximum Likelihood method were employed. Although xerostomia was reported at a low rate, many patients were at risk of malnutrition and showed varying degrees of frailty. Xerostomia was negatively associated with nutritional status and positively with frailty, while better nutritional status was linked to lower frailty. Path analysis revealed that xerostomia and nutritional status together explained nearly 50% of frailty variance. These findings underscore the importance of early identification and multidisciplinary management to reduce frailty and improve outcomes in older adults undergoing hemodialysis.

Prevalence and influencing factors of cognitive frailty in Chinese maintenance hemodialysis patients: a systematic review and meta-analysis
Abstract: 
OBJECTIVE: Chronic kidney disease (CKD) has become a major challenge in global public health, and China has one of the heaviest burdens of CKD in the world, approximately 89.5% of patients require hemodialysis. Cognitive frailty (CF) is a condition characterized by physical frailty and cognitive impairment while excluding Alzheimer's disease and other dementias. CF is associated with adverse clinical outcomes, including hospitalization, disability, and increased mortality. The purpose of this study was to explore the prevalence and influencing factors of CF in Chinese maintenance hemodialysis (MHD) patients through systematic review and meta-analysis. 
METHODS: We searched PubMed, Cochrane Library, Web of Science, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Scientific Journal Database (VIP) and Chinese Biomedical Database (CBM) for epidemiological data on CF in Chinese patients undergoing MHD from inception to December 2024. A random-effects model was used to estimate the overall prevalence of CF in Chinese patients undergoing MHD. Odds ratios (OR) and 95% confidence intervals (CI) were used to estimate factors associated with CF in Chinese patients undergoing MHD. Stata 15.0 software was used to conduct systematic review and meta-analysis of the prevalence and influencing factors of CF in Chinese patients undergoing MHD. 
RESULTS: A total of 16 studies with 5690 Chinese patients undergoing MHD were included. The results of this meta-analysis showed that the prevalence of CF in Chinese patients undergoing MHD was 25%. The results of subgroup analyses showed that the frailty assessment tool (TFI) and education level (≥ College) may be sources of heterogeneity in the prevalence of CF in Chinese patients undergoing MHD. The meta-analysis results indicate that age (> 60, > 75), female, depression (HADS scale), malnutrition, triglycerides, waist circumference, stroke history, fall history, complications, CCI, comorbidities and dialysis age were risk factors for CF. High education level, calf circumference and serum creatinine level were protective factors for CF. 
CONCLUSIONS: The prevalence of CF in Chinese patients undergoing MHD is high (25%). Therefore, this patient population necessitates early screening and targeted interventions with influencing factors.

Investigating the complex relationship and influencing factors of frailty on nutritional status in maintenance hemodialysis patients
Abstract: This review evaluates the effectiveness of nutritional supplementation combined with exercise training on frailty characteristics, physical function, and health-related quality of life in patients with chronic kidney disease (CKD). A systematic search of PubMed, Embase, Web of Science, and Scopus was conducted, identifying 7 articles (9 trials, 324 patients). Meta-analysis showed that combined interventions improved frailty characteristics, such as walking speed (mean difference: 0.09 m/s, 95% confidence interval (CI): 0.02 to 0.16) and physical functioning, including cardiorespiratory fitness (standardized mean difference: 0.56, 95% CI: 0.20 to 0.93) and lower extremity mobility (Timed Up and Go test: -1.11 s, 95% CI: -1.79 to -0.43). However, effects on body weight, fatigue, and health-related quality of life remain uncertain. Due to study heterogeneity and small sample sizes, findings should be interpreted cautiously. Larger, long-term studies are needed to confirm these results and explore additional health outcomes.

Cognitive frailty in maintenance hemodialysis: a scoping review
Abstract: 
PURPOSE: To conduct a scoping review of the related research on cognitive frailty (CF) in maintenance hemodialysis (MHD) patients, so as to provide a basis for early diagnosis, treatment and intervention of CF in MHD patients. 
METHODS: Utilizing a scoping review approach, we searched PubMed, Embase, The Cochrane Library, Web of Science, CINAHL, the China Biological Medicine Database (CBM), China National Knowledge Infrastructure (CNKI), Wanfang, and Weipu (VIP) for literature on CF in MHD patients up to October 20, 2024. Two researchers conducted independent screening and data extraction of the literature's fundamental characteristics. The study is registered in OSF (https://doi.org/10.17605/OSF.IO/H6Q89). 
RESULTS: The review included 21 articles, revealing a concerningly high prevalence of CF in MHD patients, ranging from 4.6 to 56.4%. Six diagnostic combinations were identified, with the combination of Frailty Phenotype (FP), Montreal Cognitive Assessment (MOCA), and Clinical Dementia Rating (CDR) scales being the most prevalent. Influencing factors were categorized into demographic and lifestyle, physical condition, disease-related and psychosocial aspects. Interventions included exercise, cognitive therapy combined with exercise, social support and predictive nursing, yet there remains a scarcity of intervention studies. 
CONCLUSION: The prevalence of CF in MHD patients is high; however, understanding of CF in MHD patients is insufficient. There are many types of assessment tools, but there is a lack of unified standards and specificity; the influencing factors are complex and diverse; and prevention and intervention studies are scarce.

INTRODUCTION: Given that social frailty is closely associated with adverse health outcomes among older maintenance hemodialysis (MHD) patients, this study aimed to investigate the prevalence of social frailty among older MHD patients, with an emphasis on its correlation with factors such as family functioning, self-care ability, depression, and physical frailty. METHODS: A multi-center cross-sectional investigation was conducted to recruit older patients with MHD between September and December 2024 from four hemodialysis centers in four tertiary hospitals in Sichuan Province, China. Self-report scales were employed to collect general information and assess the participants' social frailty, family functioning, depression, and physical frailty. Univariate analysis and binary logistic regression analysis were adopted to determine the predictors of social frailty. 
RESULTS: A total of 386 older MHD patients were included in the analysis. Of the participants, 205 (53.1%) were diagnosed with social frailty. Binary logistic regression analyses demonstrated that family functioning (OR = 0.863, 95% CI: 0.776-0.960, p = 0.007), self-care ability (OR = 3.527, 95% CI: 1.958-6.352, p < 0.001), depression (OR = 2.007, 95% CI: 1.180-3.415, p = 0.010), and physical frailty (OR = 2.261, 95% CI: 1.237-4.133, p = 0.008) were significantly associated with social frailty among older MHD patients. 
CONCLUSIONS: Social frailty is highly prevalent among older patients with MHD. In addition, family function, self-care ability, depression, and physical frailty were detected to be independently associated with social frailty. These findings could facilitate the refinement of daily care strategies for older patients with MHD to reduce or mitigate the negative effects of social frailty.

Frailty risk prediction models in maintenance hemodialysis patients: a systematic review and meta-analysis of studies from China
Abstract: 
OBJECTIVES: To systematically evaluate and meta-analyze the performance, validity, and influencing factors of frailty risk prediction models specifically developed for patients undergoing maintenance hemodialysis in China. 
METHODS: China National Knowledge Infrastructure, Wanfang Database, China Science and Technology Journal Database, SinoMed, PubMed, Web of Science, Cochrane Library, CINAHL and Embase were searched from inception to October 10, 2024. Two independent reviewers conducted literature screening, data extraction, and risk of bias assessment using the Prediction Model Risk of Bias Assessment Tool (PROBAST). Meta-analysis was performed to pool the incidence rates and identify independent predictors. 
RESULTS: Fourteen studies incorporating 16 distinct frailty risk prediction models were included. The predictive accuracy, measured by the area under the receiver operating characteristic curve (AUC), ranged from 0.819 to 0.998. Seven studies performed internal validation, one study executed external validation, and one study conducted both internal and external validation. All studies exhibited a high overall risk of bias. Pooled incidence of frailty among maintenance hemodialysis patients was 32.2% (95% CI: 26.9%-37.6%). Significant predictors of frailty included advanced age, hypoalbuminemia, poor nutritional status, female sex, comorbid conditions, and depression (p < 0.05). 
CONCLUSIONS: The pooled incidence of frailty among maintenance hemodialysis patients was notably high at 32.2%, with advanced age, hypoalbuminemia, poor nutritional status, female sex, comorbid conditions, and depression emerging as significant predictors. Existing frailty prediction models for maintenance hemodialysis patients demonstrated robust predictive capacity but exhibited substantial methodological limitations, high bias and limited external validation. Future research should prioritize multicenter, large sample, validation studies to enhance applicability and reliability.

Construction and Evaluation of a Novel Nomogram for Predicting Dual Dimensional Frailty in Older Maintenance Haemodialysis Patients
Abstract: 
OBJECTIVE: To construct and evaluate a novel nomogram for predicting the risk of dual dimensional frailty (comorbidity between physical frailty and social frailty) in older maintenance haemodialysis. 
METHODS: A cross-sectional investigation was conducted. A total of 386 older MHD patients were recruited between September and December 2024 from four haemodialysis centres in four tertiary hospitals in Sichuan Province, China. LASSO regression and binary logistic regression were employed to determine the predictors of dual dimensional frailty. The prediction performance of the model was evaluated by discrimination and calibration. The decision curve was utilised to estimate the clinical utility. Internal validation with 1000 bootstrap samples was conducted to minimise overfitting. 
RESULTS: In the overall sample (386 cases), a total of 92 (23.8%) of patients exhibited dual dimensional frailty. Five relevant predictors, including physical activity, self-perceived health status, ADL impairment, malnutrition, and self-perceptions of aging, were identified for constructing the nomogram. Internal validation indicated excellent discriminatory power and calibration of the model, while the clinical decision curve demonstrated its remarkable clinical utility. 
CONCLUSIONS: The novel nomogram constructed in this study holds promise for aiding healthcare professionals in identifying physical and social frailty risks among older patients on maintenance haemodialysis, potentially informing early and targeted interventions. RELEVANCE TO CLINICAL PRACTICE: This nomogram enables nurses to efficiently stratify dual-dimensional frailty risk during routine assessments, facilitating early identification of high-risk patients. Its visual output can guide tailored interventions, such as exercise programmes, nutritional support, and counselling, while optimising resource allocation. 
PATIENT OR PUBLIC CONTRIBUTION: Data were collected from self-reported conditions and patients' clinical information. 
REPORTING METHOD: STROBE checklist was employed.

Utilizing Frailty Assessment to Impact Nursing Care for Patients with End Stage Kidney Disease: A Quality Improvement Project
Abstract: Frailty is highly prevalent in patients with end stage kidney disease (ESKD) and predictive of morbidity. Nurses lack frailty education and face practical challenges to assessment, which prevent effective interventions to address frailty. A quality improvement project sought to determine if frailty education and utilization of a renal frailty index tool impacts telephonic case management nursing care of patients by improving knowledge, perception, identification, and assessment of frailty, thereby prompting nursing interventions. Positive impacts were seen across all outcomes influencing outreach and resource utilization by nurses. Limitations included a small sample size, time burden, and manual processes. Findings suggest the importance of embedding frailty care into daily practice, automation of frailty scoring, and expansion into advanced practice to improve quality of care and reduce cost of care.

BACKGROUND: The pooled prevalence of frailty in maintenance hemodialysis patients is increasing, and research on the effects of intradialytic exercise to improve frailty remains limited. 
OBJECTIVES: To analyze the effects of intradialytic exercise on frailty in maintenance hemodialysis patients through randomized clinical trials and quasi-experimental studies. METHODS: We performed a comprehensive literature search in PubMed, Embase, Web of Science, and Cochrane Library, and English-language publications were indexed from January 2010 to August 2024. Statistical analyses were performed using Review Manager V.5.3 and STATA 15.0. Statistical heterogeneity among studies was quantified using the Chi-square and I-square tests, and publication bias was evaluated using Egger's test and funnel plots. RESULTS: 31 studies involving 1,365 maintenance hemodialysis patients were included. The data from the meta-analysis showed that intradialytic exercise significantly reduced frailty score (MD = -0.98, 95%CI: 1.90 to -0.06, p = 0.04) and fatigue (SMD = -0.47, 95%CI: 0.72 to -0.23, p = 0.0001). Also, intradialytic exercise significantly increased grip strength (MD = 2.42, 95%CI:0.78 to 4.06, p = 0.004), 6-min walking distance (MD = 36.65, 95%CI:24.90 to 48.39, p < 0.0001), and step counts (SMD = 0.32, 95%CI:0.04 to 0.60, p = 0.03). However, no significant effects were found in body weight (MD = 0.71, 95%CI: 1.28 to 2.69, p = 0.48). CONCLUSION: Intradialytic exercise can significantly improve overall frailty and frailty indicators such as grip strength, 6-min walking distance, step counts, and fatigue. Thus, intradialytic exercises might be a viable strategy for frailty in maintenance hemodialysis patients.

A review of the impact of exercise on fall rates among community-dwelling older adults
Abstract: 
Background: The physical decrements of aging predispose older adults to falls and fall-related injuries. Consequences of falling place financial and logistical burdens on the health care system. With an aging population, mitigation of risk and reduction of harm are important objectives. Studies show that exercise can improve balance and build muscle mass. The challenge is prescribing safe and evidence-based exercise regimens to older adults.
Objective(s): The objective of this evidence review was to determine if an exercise program can reduce fall rates and prolong functional independence among older adults living in the community. 
Data sources: This review included 14 randomized control trials and one quasi-experimental interventional study, all published between 2014 and 2020.
Conclusion(s): The evidence suggests that a home- or community-based exercise program with formal instruction and health care provider involvement can be an effective fall-prevention and harm reduction strategy for community-dwelling older adults. 
Implications for practice: The evidence suggests that a home- or community-based exercise program may be an effective fall-prevention strategy for older adults living independently in the community. Health care providers should educate these patients about the benefits of exercise as a fall-prevention measure and assist patients in increasing participation in exercise programs by making referrals and promoting engagement in evidence-based exercise programs.

Impact of Nurses' Knowledge, Self‐Efficacy and Clinical Reasoning Competency on Difficulties in Caring for Patients With Delirium in the Intensive Care Unit: A Cross‐Sectional Study
Abstract: 
Aim: To examine the impact of critical care nurses' delirium knowledge, self‐efficacy and clinical reasoning competency on delirium care difficulties based on the information–motivation–behavioural (IMB) skills model from a behavioural perspective. 
Design: Cross‐sectional study. 
Methods: A total of 440 critical care nurses from five hospitals in China were selected using convenience sampling and invited to complete an online questionnaire for measurement. Data were collected in November 2024 and analysed using SPSS/AMOS with descriptive statistics, Pearson's correlation coefficient and multiple regression. Structural equation modelling was constructed to test the hypothesised relationships among the variables, with bootstrapping to assess mediation effects. 
Results: The level of delirium care difficulties was moderated. Delirium care difficulties were negatively correlated with delirium knowledge, self‐efficacy and clinical reasoning competency. Clinical reasoning competency partly mediated delirium knowledge and self‐efficacy with regard to delirium care difficulties. 
Conclusion: Delirium knowledge, self‐efficacy and clinical reasoning competency are essential for improving critical care nurses' delirium care competencies. The role of clinical reasoning competency in the relationship between the other two variables and delirium care difficulties was highlighted. Establishing multifaceted innovative delirium education programmes, emphasising individuals' sense of competence and enhancing clinical reasoning competency as behavioural skills were supported. Exploring these pathways using a nurse behaviour change‐based perspective is critical. 
Implications for the Profession and/or Patient Care: Critical care managers should value nurses' delirium care competencies. Enhancing continuing professional development through system‐level support with high reliability and multiform professional education, including innovative theoretical and practical training; advancing policies that increase work motivation and self‐planning to stimulate self‐efficacy; and exercising critical and reflective thinking to improve clinical reasoning competency may enhance nurses' delirium recognition and care competencies, including prioritisation, potentially improving delirium care dilemmas and patient outcomes. 
Reporting Method: The STROBE checklist was used as a guideline. 
Patient or Public Contribution: Nurses completed questionnaires.

The role of AI-driven communication in delirium prevention, detection, and care for critically ill ICU patients: A systematic review with inductive thematic synthesis
Abstract: Delirium remains one of the most consequential complications among critically ill patients in ICUs, exerting profound effects on morbidity, mortality, and annual healthcare costs exceeding $81 billion. Communication barriers between sedated or mechanically ventilated patients, their families, and multidisciplinary teams frequently delay recognition and impair management of delirium. This systematic review examines how AI-driven communication technologies can address these barriers, enhance early detection, and promote more integrated, patient- and family-centered delirium care. A systematic review of literature published between 2015 and 2025 was conducted across five electronic databases: Scopus, PubMed, Web of Science, Embase, and IEEE Xplore. The search strategy employed keywords as "delirium," "intensive care," "artificial intelligence," "AI-driven communication technologies", "natural language processing", "computer vision", "multidisciplinary clinical collaboration", and "family engagement". Studies were eligible for inclusion if they focused on AI-enhanced communication in ICU delirium care. The included studies were analyzed using an inductive thematic synthesis approach. From 87 screened records, 16 studies demonstrated AI's significant benefits across three clinical domains: 1) Prevention using AI-driven tools; 2) Early Detection via multimodal AI systems; and 3) Patient Care through Natural Language Processing (NLP)-powered support. An inductive thematic synthesis of these findings further delineated six core thematic domains: (1) inherent communication barriers; (2) AI as a multidirectional interface; (3) passive AI listening for early detection; (4) AI-enhanced family engagement; (5) AI-structured handovers for teamwork; and (6) ethical-regulatory-practical challenges. AI-driven communication tools effectively bridge critical gaps in ICU delirium care, facilitating early detection, prevention, and patient-centered management. By enabling proactive interventions and fostering a collaborative care environment, these technologies demonstrate direct potential to reduce delirium duration, decrease antipsychotic use, improve long-term cognitive outcomes, and alleviate the substantial economic burden on healthcare systems. These findings validate AI's role in transforming delirium care through enhanced multidirectional communication. ICU nurses are pivotal in utilizing AI tools through interpreting NLP-generated alerts, calibrating computer vision outputs, and facilitating family engagement to translate AI insights into empathetic, tailored bedside interventions, thereby reinforcing human-AI collaboration.

Delirium in the Elderly
Abstract: Delirium is a common and serious neuropsychiatric syndrome in older adults, characterized by acute and fluctuating disturbances in attention, awareness, and cognition. It is associated with multiple adverse outcomes, including increased mortality, functional decline, long-term cognitive impairment, and institutionalization. This review synthesizes current knowledge on the pathophysiology, risk factors, clinical presentation, diagnosis, prevention, treatment, and prognosis of delirium in elderly patients. Delirium arises from complex interactions between predisposing vulnerabilities (such as dementia, frailty, and sensory deficits) and acute precipitants (including infections, medications, surgery, and environmental stressors), resulting in a transient but often severe breakdown of cerebral function. Diagnostic tools such as the Confusion Assessment Method (CAM) and 4AT improve detection, though challenges remain in hypoactive presentations and in patients with underlying dementia. Multicomponent non-pharmacological interventions - focused on orientation, sleep hygiene, mobilization, hydration, medication review, and sensory support - are the most effective preventive and therapeutic strategies. Pharmacological treatment, primarily with antipsychotics, is reserved for severe behavioral disturbances and does not alter the course of the syndrome. Delirium is a clinical red flag indicating systemic decompensation and should prompt both acute management and structured follow-up to mitigate long-term consequences. Greater integration of delirium screening and prevention into hospital protocols is essential to improve care outcomes in this vulnerable population.

The Prevention and Treatment of Postoperative Delirium in the Elderly: A Narrative Systematic Review of Reviews
Abstract: 
Objectives: Postoperative delirium (POD) is a common complication after major surgeries, posing significant challenges to patient recovery and outcomes, particularly among the elderly. A narrative systematic review was conducted to assess the clinical effectiveness and safety of interventions aimed at preventing and treating POD. 
Methods: A review of the literature from 2017 to September 29, 2023, was conducted using MEDLINE, EMBASE, and CINAHL. Systematic reviews, with or without meta-analyses, as well as practice guidelines, were included. Participants were adults, ≥60 years. The methodological quality of included reviews was appraised using AMSTAR 2. 
Results: After the search strategy identified 2295 references, 36 review studies were selected. Multicomponent interventions, incorporating both pharmacological and nonpharmacological approaches, demonstrate promise, particularly in hip fracture patients. Notably, dexmedetomidine emerges as a potential preventive measure, showing a notable reduction in delirium incidence following cardiac surgery. While several pharmacological interventions show potential, evidence remains inconclusive, necessitating further investigation. Similarly, varying anesthesia type and monitoring methods has mixed outcomes on delirium prevention. Despite methodological variations and quality appraisal limitations, this review underscores the importance of multicomponent interventions and the potential efficacy of dexmedetomidine in mitigating POD. Integration of evidence-based protocols into clinical practice is advocated to improve patient outcomes. However, the complex interplay between intervention components calls for further research to optimize delirium management strategies. 
Conclusions: The strength of evidence associated with multicomponent interventions and dexmedetomidine use should require a genuine commitment from health care institutions to support their integration into efficient strategies to prevent and treat POD. Ongoing research is vital to uncover their full potential and refine clinical protocols, ultimately enhancing patient care outcomes.

Cost-effectiveness of adopting a postoperative delirium risk prediction tool with nonpharmacological delirium prevention interventions for surgical patients
Abstract: 
Background Postoperative delirium (POD) arises among older surgical patients. Screening followed by prevention efforts are recommended. A risk prediction tool called PIPRA plus has been developed, yet its performance and whether adoption into health services is cost-effective are unknown. 
Objective To estimate the expected change to 'total costs' and 'health benefits' measured by quality adjusted life years (QALYs) from a decision to adopt PIPRA plus for screening purpose to find at-risk individuals who are then offered nonpharmacological interventions to reduce risks of POD. 
Design Cost-effectiveness modelling study that draws on a range of relevant data sources. Setting Swiss healthcare system. Subjects Surgical inpatients aged 60 or older, excluding cardiac and intracranial surgeries. 
Methods A decision tree model was used to capture the events likely to impact on cost and health outcomes. Information was harvested from a prospective before–after study done in Switzerland and augmented with other data. Probabilistic sensitivity analysis was undertaken to reveal the probability that adoption was cost-effective against a stated maximum willingness to pay threshold for decision-making in Switzerland. 
Results Patients in both phases of the study were similar. Costs were lower by 2898 CHF (SD 1050) per patient with the adoption of the risk screening tool and there was a modest gain to health benefits of 0.01 QALY (SD 0.026). There was a 99.7% probability that adoption would be cost-saving and 91% probability that adoption would be cost-effective. 
Conclusions We provide early-stage evidence that a decision to adopt the risk screening tool and offer risk-reducing interventions could be cost-effective.

Proportional Sedation for Persistent Agitated Delirium in Palliative Care: A Randomized Clinical Trial
Abstract: 
IMPORTANCE: Neuroleptic and benzodiazepine medications are often considered for patients with persistent agitated delirium in the last days of life; however, the risk-to-benefit ratio of these medications is ill-defined and benzodiazepine medications have not been compared to placebo. 
OBJECTIVE: To compare the effect of scheduled haloperidol, lorazepam, haloperidol plus lorazepam, and placebo on patients with advanced cancer and delirium and experiencing restlessness and/or agitation in the palliative care setting. 
DESIGN, SETTINGS, AND PARTICIPANTS: This multicenter randomized clinical trial was conducted at 3 acute palliative care units in Taiwan and the US with patients with advanced cancer experiencing persistent restlessness and/or agitation despite nonpharmacologic therapies and standard-dose haloperidol. Among 245 eligible patients, 111 were enrolled, and 75 received blinded treatments. Participants were randomized in a 1:1:1:1 ratio (stratified by site and Richmond Agitation-Sedation Scale [RASS] score). The study period was from July 16, 2019, to June 8, 2023, with a 30-day follow-up after medication administration. Data analysis was performed from October 10, 2023, to April 11, 2025. 
INTERVENTIONS: Scheduled intravenous haloperidol, lorazepam, haloperidol plus lorazepam, or placebo every 4 hours until discharge, death, or withdrawal from study. Medications in all 4 groups had identical volume and appearance. 
MAIN OUTCOMES AND MEASURES: Change in RASS scores during the first 24 hours. Secondary outcomes included the use of rescue neuroleptics or benzodiazepines for breakthrough restlessness or agitation during the first 24 hours, delirium severity, perceived patient comfort, and adverse events. 
RESULTS: The primary outcome was assessed in 72 patients (mean [SD] age, 64 [12] years, 42 male [58%]) with a median (IQR) MDAS score of 24 (18-29). The lorazepam group had significantly lower RASS scores than the haloperidol group (mean difference, -2.1; 95% CI, -3.4 to -0.9; P < .001) and the combination group had significantly lower RASS scores than the haloperidol group (-2.0; 95% CI, -3.2 to -0.8; P = .002); however, there was no difference observed between haloperidol and placebo groups (-0.5; 95% CI, -1.7 to 0.7; P = .42) nor between the combination and lorazepam groups (0.2; 95% CI, -1.1 to 1.4; P = .79). The combination and lorazepam groups required fewer rescue medications for breakthrough restlessness or agitation compared to the haloperidol and placebo groups (32%, 37%, 56%, 83%, respectively; P = .006). Adverse events or survival did not differ between groups. 
CONCLUSIONS AND RELEVANCE: The results of this randomized clinical trial indicate that proactive use of scheduled sedatives, particularly lorazepam-based regimens, may reduce persistent restlessness and/or agitation in patients with advanced cancer and delirium in the palliative care setting.

4AT screening for delirium in dementia: meta-analysis of diagnostic performance
Abstract: Delirium is frequently underdiagnosed in older adults, especially those with dementia, due to overlapping clinical features. In this meta-analysis, we evaluate the diagnostic performance of the 4 'A's Test (4AT) in detecting delirium specifically among dementia patients. Five eligible diagnostic accuracy studies were identified in a systematic search in six databases, comprising 1,304 older adults, including 482 with dementia. Pooled sensitivity and specificity were 88 and 79%, respectively, with a diagnostic odds ratio of 32.0, indicating strong discriminatory power. The 4AT high sensitivity supports its use as an initial screening tool to rule out delirium in dementia patients, especially in acute or resource-limited settings. However, moderate specificity highlights the need for confirmatory assessments in positive cases. In this review, we underscore the clinical utility of the 4AT for rapid delirium detection in complex geriatric populations and recommend further research on its performance across dementia subtypes and healthcare environments.

Misdiagnosing Urinary Tract Infections as Delirium in Older Adults: A Systemic Review of Evidence from Ireland and the UK...72nd Annual Scientific Meeting (ASM) of Irish Gerontological Society (IGS), October 2-4, 2025, Killlarney, Ireland
Abstract: 
Background: Delirium is a common, serious, and often under-recognized condition in older adults. Misdiagnosis as urinary tract infection (UTI) is widespread, particularly in institutional care settings, leading to inappropriate antibiotic use and poorer health outcomes. 
Methods: A systematic review was conducted according to PRISMA guidelines. Literature searches were done using the PubMed, EMBASE, Cochrane, and HSE Library databases, focusing on studies published between 2015 and 2025. The inclusion criteria were studies that assessed the diagnosis of urinary tract infections (UTIs) in adults aged 65 and older with delirium, conducted in Ireland or the UK, and reported clinical outcomes. Data extraction concentrated on study design, sample size, care setting, diagnostic tools use, and misdiagnosis rates. The quality of the studies was evaluated using the NewcastleOttawa Scale (NOS). A meta-analysis was carried out using a random-effects model in RevMan 5.4. 
Results: The misdiagnosis rate of UTIs in older adults with delirium was 36% (95% CI: 29–42%), with over one-third of delirium cases wrongly attributed to UTIs. Long-term care facilities had the highest misdiagnosis rate at 42%, followed by emergency departments at 35% and hospital wards at 28%. About 65% of misdiagnosed cases relied solely on positive dipstick results, causing frequent false positives. Only 40% of cases utilized standardized delirium screening tools. Empiric antibiotic therapy was prescribed in 37% of misdiagnosed cases without confirmatory urine cultures, raising concerns about antimicrobial overuse and associated risks such as adverse drug reactions and resistant infections. 
Conclusion: UTI misdiagnosis remains a major barrier to accurate delirium management in older adults. Our findings target urgent policy action to standardize delirium screening, restrict inappropriate antibiotic use, and train healthcare staff. Embedding tools like 4AT in EMR, enhancing clinical governance through audits, and aligning with HSE/NICE antimicrobial guidelines could reduce diagnostic error and improve outcomes in geriatric population.

A Focused Update to the Clinical Practice Guidelines for the Prevention and Management of Pain, Anxiety, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU
Abstract: 
RATIONALE: Critically ill adults are at risk for a variety of distressing and consequential symptoms both during and after an ICU stay. Management of these symptoms can directly influence outcomes. 
OBJECTIVES: The objective was to update and expand the Society of Critical Care Medicine's 2018 Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU. 
PANEL DESIGN: The interprofessional inclusive guidelines task force was composed of 24 individuals including nurses, physicians, pharmacists, physiotherapists, psychologists, and ICU survivors. The task force developed evidence-based recommendations using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Conflict-of-interest policies were strictly followed in all phases of the guidelines, including task force selection and voting. 
METHODS: The task force focused on five main content areas as they pertain to adult ICU patients: anxiety (new topic), agitation/sedation, delirium, immobility, and sleep disruption. Using the GRADE approach, we conducted a rigorous systematic review for each population, intervention, control, and outcome question to identify the best available evidence, statistically summarized the evidence, assessed the quality of evidence, and then performed the evidence-to-decision framework to formulate recommendations. 
RESULTS: The task force issued five statements related to the management of anxiety, agitation/sedation, delirium, immobility, and sleep disruption in adults admitted to the ICU. In adult patients admitted to the ICU, the task force issued conditional recommendations to use dexmedetomidine over propofol for sedation, provide enhanced mobilization/rehabilitation over usual mobilization/rehabilitation, and administer melatonin. The task force was unable to issue recommendations on the administration of benzodiazepines to treat anxiety, and the use of antipsychotics to treat delirium. 
CONCLUSIONS: The guidelines task force provided recommendations for pharmacologic management of agitation/sedation and sleep, and nonpharmacologic management of immobility in critically ill adults. These recommendations are intended for consideration along with the patient's clinical status.

Enhancing Delirium Prediction in ICU Older Patients Through the 5-Factor Modified Frailty Index
Abstract: 
Background: Delirium and frailty are prevalent in the ICU, yet there is a paucity of research utilising frailty as determined by the 5‐factor modified frailty index (mFI‐5) to examine its correlation with delirium in intensive care unit (ICU) older patients. 
Aim: The aim of this research was to explore the association between the mFI‐5 and the occurrence of delirium in older patients admitted to the ICU, while assessing the mFI‐5's predictive value for delirium. Study Design: This study employed data extracted from the Medical Information Mart for Intensive Care IV database. The participants were classified into three groups based on their mFI‐5 scores: non‐frail (mFI‐5 = 0), intermediate frailty (mFI‐5 = 1) and high frailty (mFI‐5 ≥ 2). The predictive value of mFI‐5 for delirium was evaluated using the area under the curve, the net reclassification improvement and the integrated discrimination improvement metrics. Results: Delirium was observed in 9919 of the 30 280 patients included in the study. Patients with intermediate frailty (adjusted odds ratios OR]: 1.38, 95% CI: 1.28–1.48, p < 0.001) and high frailty (adjusted OR: 1.83, 95% CI: 1.69–1.97, p < 0.001) exhibited a markedly elevated risk of delirium in comparison to non‐frail patients. Furthermore, the incorporation of the mFI‐5 into the multivariate model markedly enhanced its predictive accuracy for delirium. Conclusions: Frailty as assessed by the mFI‐5 is strongly correlated with an elevated risk of delirium in older ICU patients. The incorporation of the mFI‐5 into delirium prediction models may enhance the predictive accuracy of these models. Relevance to Clinical Practice: The mFI‐5 is a valuable tool for identifying older ICU patients at higher risk of delirium, aiding in early intervention and tailored care.

Validation of the 4AT for assessing recovery from delirium in older hospital patients
Abstract: 
Background A crucial part of delirium care is assessing for recovery, yet there are no validated methods for this. The 4AT is a widely used delirium assessment tool, but its performance in assessing recovery remains unstudied. This study evaluated the 4AT's performance in assessing recovery from delirium. 
Materials and methods In this prospective diagnostic accuracy study, older hospitalised patients (≥70 years) with reference standard delirium on enrolment were assessed 2–4 times over ≤9 days. Paired researchers independently conducted blinded assessments of (i) a reference standard (Diagnostic and Statistical Manual for Mental Disorders, 5th edition), including the Delirium Rating Scale-Revised-98 and neuropsychological tests and (ii) the 4AT (index test, score ≥ 4 positive) plus brief measures of distress and psychotic symptoms. 
Results A total of 120 people with delirium participated median age 86.3, range 70–99, 67 (55.8%) female and 55 (45.8%) with dementia]. All of them completed the first two assessments, 103 (85.8%) completed three and 69 (57.5%) four. Reference standard delirium was present in 102/120 (85%), 72/103 (69.9%) and 53/69 (76.8%) cases at assessments two to four, respectively. In Receiver Operating Characteristic analyses, the 4AT's sensitivity for detecting delirium was 0.95 (confidence interval 0.91–0.99), 0.96 (0.91–1) and 0.94 (0.88–1), and specificity was 0.67 (0.13–1), 0.88 (0.71–1) and 1 (1–1) at assessments two to four. In total 18 (15%) participants recovered from delirium. Distress was common in delirium and decreased with recovery. 
Conclusion The 4AT maintains diagnostic accuracy on repeated admissions and may effectively assess delirium recovery in acute hospital settings. Fewer patients than expected recovered within 9 days, suggesting more studies on the natural history of delirium in different settings would be informative.

Melatonin for prevention of delirium in patients receiving mechanical ventilation in the intensive care unit: a multiarm multistage adaptive randomized controlled clinical trial (DEMEL)
Abstract: 
PURPOSE: To determine the dose of melatonin with an optimal pharmacokinetic profile and to test whether this dose reduces the prevalence of delirium in mechanically ventilated ICU patients as compared to placebo. 
METHODS: DEMEL, a multicenter adaptive phase 2b/3 randomized, placebo-controlled, double-blind trial included patients at 20 health centers in France from February 1st, 2019 through January 5th, 2021. Patients were randomized (1:1:1) to receive either placebo or low (0.3 mg) or high (3 mg) dose melatonin enterally at 9:00 p.m. for 14 consecutive nights or until death or ICU discharge, whichever came first. The interim primary endpoint (activity stage) was the percentage of patients who achieved an optimal melatonin pharmacokinetic profile 24 h after starting study treatment; the final primary endpoint (efficacy phase) was the percentage of patients who experienced delirium between randomization and day 14 (or until death or ICU discharge, whichever came first). Delirium was assessed twice daily using the Confusion Assessment Method for ICU. 
RESULTS: We randomized 355 patients and included 334 in the primary analysis. At the preplanned analysis of the activity stage performed in 75 patients, the low-dose melatonin group had the highest rate of optimal pharmacokinetic profiles (12/24, 50%) when compared with the high-dose melatonin group (6/25, 24%) and the placebo group (0/26). Therefore, the Steering Committee recommended that the high-dose melatonin group be discontinued and that the low-dose melatonin group be selected to continue in the efficacy phase along with the placebo group. At the end of the efficacy stage, there was no difference in the final primary outcome of delirium incidence between the low-dose melatonin group and the placebo group: 80/147 (54.4%) vs 85/154 (55.2%), risk ratio, 0.986 [95% CI 0.803 to 1.211]; key secondary outcomes were also similar between groups. These included sleep quality, delirium-free, coma-free, and ventilator-free days at day 28; ICU and hospital length of stay; mortality at day 28, in the ICU, and in hospital; as well as long-term outcomes such as quality of life and postintensive care syndrome at day 90. 
CONCLUSIONS: This randomized clinical trial found that the low-dose of melatonin (0.3 mg nightly) achieved a better pharmacokinetic profile than the high-dose (3 mg nightly), but did not change the incidence of delirium compared to placebo in mechanically ventilated critically-ill patients.

Social Disparities, Delirium Occurrence, and Related Outcomes Among Hospitalized Older Adults
Abstract: 
Background: Underlying socio‐economic and health burden may variably impact delirium presentation among older adults. We characterized differences in patient factors related to social marginalization and studied their effects on delirium occurrence and hospital outcomes. Methods: We conducted a 7‐year retrospective analysis of older adults (aged ≥ 70 years) who systematically underwent screening for delirium at an 8‐hospital healthcare system. Our primary exposure included patient characteristics related to demographics and social marginalization. Multivariable logistic regression models were built to identify factors associated with increased odds of delirium occurrence, either (1) present‐on‐admission (D‐POA) or (2) hospital‐acquired (HAD). Secondary outcomes included hospital length of stay, in‐hospital mortality, and discharge disposition. 
Results: A total of 260,200 older adults were screened for delirium (median IQR] age in years: 78.0 74.0–84.0]; female: 143,402 55.1%]; non‐Hispanic Black: 40,737 15.8%]; Hispanic: 30,760 11.9%]; median IQR] Area Deprivation Index: 4.0 2.0–6.0]; median IQR] Charlson Comorbidity Index: 10.0 8.0–13.0]). Rates of D‐POA were 25.5% across all screened patients. Among patients delirium‐free at admission, 10.4% later acquired HAD. In addition to known risk associations with older age and comorbidity burden, increased odds of D‐POA were observed for non‐Hispanic Black patients (aOR, 95% CI: 1.49, 1.44–1.54), Hispanic patients (aOR, 95% CI: 1.31, 1.26–1.36), higher ADI‐defined socio‐economic marginalization (aOR, 95% CI: 1.01, 1.00–1.01), and prior dementia (aOR: 6.53, 6.37–6.68). HAD risks were also higher for males (aOR, 95% CI: 1.07, 1.04–1.11), non‐Hispanic Black patients (1.39, 1.32–1.46), Hispanic patients (aOR, 95% CI: 1.28, 1.21–1.35), residence in higher ADI neighborhoods (aOR, 95% CI: 1.02, 1.02–1.03), and prior dementia (aOR, 95% CI: 2.44, 2.34–2.53). Effects of delirium on poor hospital outcomes did not differ by socio‐demographic sub‐groups. 
Conclusions: Delirium risks were higher among minoritized and socio‐economically marginalized older adults. These findings present an opportunity to consider social marginalization as an important factor in delirium risk stratification.

Time to routinely perform 4AT at the 'front door'; evidence informing policy and practice
Abstract: The article focuses on the use of the 4′A′s Test (4AT) as a screening tool for identifying delirium and dementia in older patients during hospital admissions. It advocates for a 'front door' triple assessment, which includes the national early warning score, clinical frailty score, and 4AT, for all patients over 65 presenting to emergency departments. A study involving over 75,000 older adult admissions found that while the 4AT is effective in identifying existing dementia and delirium, there are still instances of false negatives, highlighting the need for comprehensive clinical assessments. The article emphasizes the importance of embedding 4AT screening into routine care to improve early diagnosis and management of these conditions, ultimately enhancing patient outcomes and care transitions.

Using scores from the 4AT delirium detection tool as an indicator of possible dementia: a study of 75 221 older adult hospital admissions
Abstract: Introduction Overall dementia diagnosis rates are substantially below true rates. Hospital admissions of older people involve cognitive and functional assessments relevant to dementia diagnosis. These assessments could be harnessed to contribute to identifying patients for further assessment. Yet relationships of inpatient cognitive tests with known dementia are unclear. The 4AT (www.the4AT.com) assesses for delirium (Scores 4–12) and also cognitive impairment via embedded cognitive tests (Scores 1–3). We investigated relationships between 4AT scores and clinical dementia diagnoses. Methods We included participants aged ≥65 years admitted as a medical emergency to three hospitals from 4 January 2016 to 4 January 2020, who had the 4AT performed on admission. Clinical dementia diagnosis was ascertained from linked primary care, hospital discharge and community prescribing data. Results Of 75 221 admissions, 62 188 (82.7%; 33 625 unique patients; mean age 80.2 years; 55.8% female) had a 4AT on admission. Of these, 9948 (16.0%) had a recorded clinical dementia diagnosis at the time of admission, with a further 1197 (1.9%) receiving a new diagnosis at discharge. Of admissions with dementia, 9669/11 145 (86.8%) had a 4AT score ≥1 on admission, compared to 14 994/51 043 (29.4%) without dementia. 4AT ≥1 had a sensitivity of 0.87 (95% CI 0.86–0.87) and a specificity of 0.71 (0.70–0.71) in relation to clinical dementia diagnosis. 4AT ≥4 showed sensitivity of 0.50 (0.50–0.51) and a specificity of 0.88 (0.88–0.88). Conclusions 4AT scores were associated with clinically diagnosed dementia. These results suggest that routinely collected 4AT scores could be leveraged in conjunction with other clinical indicators to identify patients with possible undiagnosed dementia who could undergo further inpatient diagnostic assessment and/or post-discharge specialist follow-up.

Long-term clinical outcomes of delirium after hospital discharge: a systematic review and meta-analysis
Abstract: 
Background Delirium has been linked to adverse health outcomes. There has not been a comprehensive attempt to synthesise these outcomes. 
Objective To synthesise evidence comparing post-discharge clinical outcomes in individuals who experienced delirium in hospital compared to those who did not. 
Methods A systematic electronic search was conducted in Medline, Embase, CINAHL, PsycINFO and Cochrane databases. Random-effects models were used to assess effect size differences between those who experienced delirium and those who did not: odds ratios (OR) for categorical outcomes and Hedges' g for continuous outcomes. Analyses were conducted for each outcome relative to ≤6 months, >6–12 months, 12+ months and collapsed across time post-discharge. 
Results Data were synthesised from 253 studies representing 29 814 participants who experienced delirium and 107 583 participants who did not experience delirium. The mean (SD) age of participants was 76.0 (9.3) years. Collapsed over follow-up period, results included, those who experienced delirium in hospital showed higher objective cognitive decline (OR = 1.58, P <.001), greater subjective cognitive impairment (OR = 2.11, P =. 041), greater functional decline (g = −0.43, P =. 001), lower quality of life (g = −0.44, P <.001), higher burden of poor mental health (OR = 1.69, P <.001), increased risk of dementia (OR = 5.37, P <.001), higher likelihood of institutionalisation (OR = 2.80, P <.001), greater rates of hospital readmission (OR = 1.70, P <.001) and increased mortality (OR = 2.55, P <.001) post-hospital discharge compared to those who did not experience delirium in hospital. Time-specific analyses did not reveal any consistent patterns of effects. 
Conclusions Older adults who experience delirium in hospital demonstrate significantly worse long-term clinical outcomes compared to those who do not.

Comparative effectiveness of delirium recognition with and without a clinical decision assessment system on outcomes of hospitalized older adults: Cluster randomized controlled trial
Abstract: Early recognition of delirium is essential for effective management, but it often goes unrecognized, resulting in adverse outcomes. Clinical decision support systems can enhance adherence to guidelines and improve patient outcomes. We developed a mobile-based clinical decision assessment tool (3D-DST) based on the 3-minute diagnostic interview for confusion assessment method-defined delirium (3D-CAM). Implementing the 3D-DST may enhance delirium recognition and adherence to interventions among healthcare professionals, potentially improving outcomes in older adults. To test whether improved recognition of delirium could lead to better clinical outcomes in older adults. A cluster randomized controlled trial with pair-matching. A tertiary geriatric hospital. Patients aged ≥ 65 years. Four general wards were paired and randomly assigned to the intervention group (two wards) or the control group (two wards). The intervention included routine delirium assessments by nurses using either the 3D-DST or the 3D-CAM, along with delirium prevention and intervention measures carried out by a multidisciplinary team. Outcomes measured included delirium incidence, duration, severity, length of stay, and adherence to the delirium assessment, prevention, and treatment protocol. A trained nursing researcher collected data on demographics, clinical characteristics, and primary and secondary outcomes. 211 eligible patients participated (106 in the intervention group and 105 in the control group), with 21 identified as delirium-positive using the 3D-DST. The median Charlson comorbidity index score among older adults in the intervention group was 1 (1–2), compared to 2 (1–3) in the control group (P = 0.032). Nurses' adherence to delirium assessment was significantly higher in the intervention group than in the control group (73 % vs. 31 %). The recognition rate of delirium among nurses was 89 % in the intervention group and 42 % in the control group. There were no statistically significant differences in delirium duration (6 3–9] vs. 7 2–14], P = 0.967), incidence (8.5 % vs. 11.4 %, P = 0.500), severity (2 1–3] vs. 2 1–4], P = 0.891) or length of hospital stay (15 14–18] vs. 18 13–22], P = 0.568) between the intervention and control groups. The 3D-DST enhanced adherence to routine delirium recognition by nurses. However, effective strategies are urgently needed to strengthen multidisciplinary collaboration and enhance adherence to delirium management among healthcare professionals.

OBJECTIVE: This systematic review aims to evaluate optimal early screening strategies, significant risk factors, and effective diagnostic and management approaches for delirium in critically ill geriatric surgical patients. 
DATA SOURCES: A comprehensive search was conducted across five databases: PubMed, Google Scholar, ProQuest, Embase, and Cochrane. 
STUDY SELECTION: Studies were included based on their relevance to early screening, risk factors, diagnostic accuracy, and management strategies for delirium in critically ill geriatric surgical patients. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. 
DATA EXTRACTION: A total of 31 studies met the inclusion criteria. Outcomes of interest included effective early screening/prevention strategies, significant risk factors, sensitive diagnosis tools, and effective management strategies. 
DATA SYNTHESIS: Early screening strategies, including advanced neural networks and E-PROD-NS, demonstrated high sensitivity and specificity (area under the receiver operating characteristic curve >0.76). Key risk factors included advanced age, renal dysfunction, cognitive impairment, prolonged intensive care unit length of stay (ICU-LOS), and mechanical ventilation time. Diagnostic tools such as the 4A's test and serum biomarkers exhibited superior accuracy compared to the ICU Confusion Assessment Method and Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) criteria. Management strategies effectively reduced delirium duration, including acetaminophen, environmental modifications, and family involvement. 
CONCLUSIONS: E-PROD-NS and the 4A's test were associated with early delirium detection and intervention. Risk factors for delirium included advanced age, renal dysfunction, and existing cognitive dysfunction. Mitigating mechanical ventilation and ICU-LOS duration, treatment with acetaminophen, and environmental modifications reduced delirium duration in critically ill geriatric surgical patients.

BACKGROUND: Delirium is a serious neuropsychiatric syndrome with adverse outcomes, which is common but often undiagnosed in terminally ill people. The 4 'A's test or 4AT (www.the4AT.com), a brief delirium detection tool, is widely used in general settings, but validation studies in terminally ill people are lacking. 
AIM: To determine the diagnostic accuracy of the 4AT in detecting delirium in terminally ill people, who are hospice inpatients. 
DESIGN: A diagnostic test accuracy study in which participants underwent the 4AT and a reference standard based on the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. The reference standard was informed by Delirium Rating Scale Revised-98 and tests assessing arousal and attention. Assessments were conducted in random order by pairs of independent raters, blinded to the results of the other assessment. 
SETTING/PARTICIPANTS: Two hospice inpatient units in Scotland, UK. Participants were 148 hospice inpatients aged ⩾18 years. 
RESULTS: A total of 137 participants completed both assessments. Three participants had an indeterminate reference standard diagnosis and were excluded, yielding a final sample of 134. Mean age was 70.3 (SD = 10.6) years. About 33% (44/134) had reference standard delirium. The 4AT had a sensitivity of 89% (95% CI 79%-98%) and a specificity of 94% (95% CI 90%-99%). The area under the receiver operating characteristic curve was 0.97 (95% CI 0.94-1). 
CONCLUSION: The results of this validation study support use of the 4AT as a delirium detection tool in hospice inpatients, and add to the literature evaluating methods of delirium detection in palliative care settings. TRIAL REGISTRY: ISCRTN 97417474.

Diagnostic Accuracy of the Recognizing Acute Delirium as Part of Your Routine (RADAR) Scale for Delirium Assessment in Hospitalized Older Adults: A Cross-Sectional Study
Abstract: Delirium is highly prevalent among hospitalized older adults and is associated with unfavorable outcomes. However, delirium often remains undiagnosed in the hospital context. Having a valid, simple, and fast screening tool could help in limiting the additional workload for healthcare professionals, without leaving delirium undetected. The aim of this study was to estimate the sensitivity and specificity of the Recognizing Acute Delirium As part of your Routine (RADAR) scale in an Italian hospital. An observational cross-sectional study was conducted. A total of 150 patients aged ≥70 years were enrolled. Receiver operating characteristic (ROC) curves using the Confusion Assessment Method (CAM) criterion-defined delirium as the gold standard were plotted to evaluate the performance of the RADAR scale. The cut-off suggested by previous research was used to estimate the sensitivity, specificity, and positive and negative predictive values of the RADAR scale. The involved patients were mostly females (60%; n = 90), with a median age of 84 years (I-III quartiles: 80-88). According to the CAM and the RADAR scale, 37 (25%) and 58 (39%) patients were classified as experiencing delirium, respectively. The area under the ROC curve of the RADAR scale was 0.916. Furthermore, the RADAR scale showed robust sensitivity (95%), specificity (80%), and positive (60%) and negative predictive values (98%). The RADAR scale is thus suggested to be a valid tool for screening assessment of delirium in hospitalized older adults.

The 4AT scale for rapid detection of delirium in emergency department triage
Abstract: 
AIMS: To assess the diagnostic accuracy and time impact of the 4AT scale in emergency department triage. 
METHODS: A Prospective diagnostic accuracy study was carried out. People aged ≥65 years presenting to the emergency department from 1 November 2021 to 30 June 2022 were included. Nurses opportunistically screened eligible patients using the 4AT scale during triage according to the Manchester Triage System Francesc de Borja Hospital emergency department, Gandía (Spain). Accuracy was compared with medical diagnosis of delirium. Time (seconds) spent in triage with and without screening was assessed. 
RESULTS: The study included 370 patients (55.1% men, mean age 81.8 years), of whom 58.4% (n = 216) were screened. A final diagnosis of delirium was made in 41.4% of those screened. The most frequently used presentational flow charts and discriminators were 'behaving strangely' (15%) and 'rapid onset' (33.3%). The highest accuracy was obtained for a score of 3 points or more (sensitivity 85.1%; specificity 66.9%; positive predictive value 52.8%; negative predictive value 71.7%). No significant differences were found in the time spent in triage according to the performance of screening. 
CONCLUSION: A score of 3 points or more on the 4AT scale enables rapid detection of delirium in emergency department triage, without consuming more time than conventional triage.

Diagnostic accuracy of the 4AT for delirium: A systematic review and meta-analysis
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.

AIM: To assess the feasibility of delirium screening with the screening tool 4AT conducted by stroke unit nurses. DESIGN: Observational. 
METHODS: Patients with confirmed acute stroke admitted to the stroke unit at Baerum Hospital, Norway, from March to October 2020, were consecutively recruited. Nurses performed delirium screening using the rapid screening tool 4AT within 24 h of admission, at discharge and when delirium was suspected, and filled out a questionnaire assessing their experiences with the delirium screening. A geriatrician validated the delirium diagnosis. RESULTS: In all, 62 patients were included, mean age 73.3 years. 4AT was performed according to protocol in 49 (79.0%) and 39 (62.9%) patients at admission and discharge respectively. Lack of time (40%) was reported as the most common reason for not performing delirium screening. The nurses reported that the felt competent to carry out the 4AT screening, and did not experience it as significant extra workload. Five patients (8%) were diagnosed with delirium. Delirium screening performed by stroke unit nurses seemed feasible and the nurses experienced that 4AT was a useful tool for this purpose.

Delirium assessment tools among hospitalized older adults: A systematic review and metaanalysis of diagnostic accuracy
Abstract: Delirium is a common neuropsychiatric syndrome that is often overlooked in clinical settings. The most accurate instrument for screening delirium has not been established. This study aimed to compare the diagnostic accuracy of the 4 'A's Test (4AT), Nursing Delirium Screening Scale (Nu-DESC), and Confusion Assessment Method (CAM) in detecting delirium among older adults in clinical settings. These assessment tools feature concise item sets and straightforward administration procedures. Five electronic databases were systematically searched from their inception to September 7, 2022. Studies evaluating the sensitivity and specificity of the 4AT, Nu-DESC, and CAM against the Diagnostic and Statistical Manual of Mental Disorders or International Classification of Diseases as the reference standard were included. Bivariate random effects model was used to summarize the sensitivity and specificity results. A total of 38 studies involving 7378 patients were included. The 4AT, Nu-DESC, and CAM had comparable sensitivity in detecting delirium (0.76, 0.78, and 0.80, respectively). However, the specificity of the CAM was higher than that of the 4AT (0.98 vs 0.89, P = .01) and Nu-DESC 0.99 vs 0.90, P = .003). Diagnostic accuracy was moderated by the percentage of women, acute care setting, sample size, and assessors. The three tools exhibit comparable sensitivity, and the CAM has the highest specificity. Based on the feasibility of the tools, nurses and clinical staffs could employ the Nu-DESC and the 4AT on screening out positive delirium cases and integrate these tools into daily practice. Further investigations are warranted to verify our findings.

PURPOSE: To assess the clinical implementation and barriers to completing the 4AT for delirium in general medical and geriatric patients over 75 years upon admission to Wellington and Kenepuru Hospitals during the first eight months of 2017, 2018 and 2019. METHODS: Retrospective data from electronic health records were analysed using an explanatory-sequential mixed-methods approach. The initial quantitative phase measured doctors' adherence to the 4AT and the rate of positive 4ATs (≥ 4). The subsequent qualitative phase identified doctors' main reasons for omitting the 4AT through conventional content analysis. 
RESULTS: The quantitative population included 7799 acute admissions (mean age 84, 58.2% female). There was good clinical implementation of the 4AT, evidenced by an overall adherence rate of 83.2% and a rate of positive 4ATs of 14.8% that is in keeping with expected delirium rates in similar settings. The qualitative sample consisted of 875 acute admissions (mean age 84, 56.3% female) with documented reasons for omitting the 4AT. The main barriers to completing the 4AT were: reduced patient alertness, communication barriers (language, deafness, aphasia and dysarthria), prioritising patients' wellness and comfort (addressing critical illnesses, symptoms, end-of-life issues and promoting sleep), pre-existing cognitive disorders, and unstructured delirium assessments. 
CONCLUSION: Adherence to the 4AT was high and sustainable in both hospitals. Most barriers to completing the 4AT were potentially avoidable. Education about the 4AT in relation to these barriers may improve its implementation.

A prospective study of remote delirium screening using the modified K-4AT for COVID-19 inpatients
Abstract: 
BACKGROUND: Delirium is a neuropsychiatric condition strongly associated with poor clinical outcomes such as high mortality and long hospitalization. In the patients with Coronavirus disease 2019 (COVID-19), delirium is common and it is considered as one of the risk factors for mortality. For those admitted to negative-pressure isolation units, a reliable, validated and contact-free delirium screening tool is required. 
MATERIALS AND METHODS: We prospectively recruited eligible patients from multiple medical centers in South Korea. Delirium was evaluated using the Confusion Assessment Method (CAM) and 4'A's Test (4AT). The attentional component of the 4AT was modified such that respondents are required to count days, rather than months, backward in Korean. Blinded medical staff evaluated all patients and determined whether their symptoms met the delirium criteria of the Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5). An independent population of COVID-19 patients was used to validate the 4AT as a remote delirium screening tool. We calculated the area under the receiver operating characteristic curve (AUC). 
RESULTS: Out of 286 general inpatients, 28 (9.8%) inpatients had delirium. In this population, the patients with delirium were significantly older (p = 0.018) than the patients without delirium, and higher proportion of males were included in the delirium group (p < 0.001). The AUC of the 4AT was 0.992 [95% confidence interval (CI) 0.983-1.000] and the optimal cutoff was at 3. Of the independent COVID-19 patients, 13 of 108 (12.0%) had delirium. Demographically, the COVID-19 patients who had delirium only differed in employment status (p = 0.047) from the COVID-19 patients who did not have delirium. The AUC for remote screening using the 4AT was 0.996 (0.989-1.000). The optimal cutoff of this population was also at 3. 
CONCLUSION: The modified K-4AT had acceptable reliability and validity when used to screen inpatients for delirium. More importantly, the 4AT efficiently screened for delirium during remote evaluations of COVID-19 patients, and the optimal cutoff was 3. The protocol presented herein can be used for remote screening of delirium using the 4AT.

Delirium screening with 4AT in patients aged 65 years and older admitted to the Emergency Department with suspected sepsis: a prospective cohort study
Abstract: 
PURPOSE: We aimed to study the use of The 4 'A's test (4AT), a rapid delirium screening tool, performed upon Emergency Department (ED) admission, and to characterize older patients admitted to the ED with and without sepsis in terms of delirium features. 
METHODS: In this prospective cohort study, we included patients aged ≥ 65 years, admitted to the ED with suspected sepsis. ED nurses and doctors performed delirium screening with 4AT within two hours after ED admission, and registered the time spent on the screening in each case. Sepsis and delirium during the hospital stay were diagnosed retrospectively, according to recommended diagnosis criteria. 
RESULTS: Out of the 196 patients included (mean age 81 years, 60% men), 100 patients fulfilled the sepsis diagnosis criteria. The mean 4AT screening time was 2.5 Minutes. In total, 114 patients (58%) had a 4AT score ≥ 1, indicating cognitive impairment, upon ED admission. Sepsis patients more often had a 4AT score ≥ 4, indicating delirium, than patients without sepsis (40% vs. 26%, p < 0.05). Out of the 100 patients with sepsis, 68 (68%) had delirium during the hospital stay, as compared to 34 out of 96 patients (35%) without sepsis (p < 0.05). CONCLUSION: Delirium screening upon ED admission, using 4AT, was feasible among patients aged ≥ 65 years admitted with suspected sepsis. Two out of three patients had at least one feature of delirium upon admission. The prevalence of delirium during the hospital stay was high, particularly in patients with sepsis. Delirium screening with 4AT in the Emergency Department.

Is the 4AT Score Accurate in Identifying Delirium in Older Adults?
Abstract: Take-Home Message
The 4 A’s Test (4AT) has good diagnostic accuracy for detecting delirium in patients aged 65 years or older across different hospital settings.
Methods
Data Sources
Two authors searched the Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, EMBASE, PsycINFO, Web of Science Core Collection, MEDLINE, Cumulative Index of Nursing and Allied Health Literature Plus, Database of Abstracts of Reviews of Effects, and ClinicalTrials.gov from 2011 at the release of the 4AT score to December 21, 2019. Authors used search terms to comprehensively capture 4AT scores, as well as organic causes of delirium. There were no language restrictions.
Study Selection
Authors included studies with the following criteria: study population comprised patients aged 65 years or older, evaluated the diagnostic accuracy of the 4AT score for delirium, referenced a standard delirium tool with diagnostic criteria or a validated tool, and used a cross-sectional, retrospective, or prospective cohort design. In studies assessing patients younger and older than the age threshold, the authors contacted the original study authors to obtain the data for only those older than the age threshold. They excluded patients with delirium tremens. Two authors independently assessed studies for relevance and resolved disagreements through discussion, arbitrated by a third author.
Data Extraction and Synthesis
Two pairs of investigators independently extracted data from included studies, with discrepancies resolved by a third author or discussion. The primary outcome was identification of delirium by the 4AT score. The authors stratified subgroup analyses by assessing sensitivity and specificity when including only studies at low risk of bias, excluding retrospective studies, and excluding stroke patients. Investigators estimated sensitivity and specificity with 95% confidence interval, using a bivariate random-effects model. Summary estimates of sensitivities and specificities were calculated with receiver operating characteristics plots. Risk of bias and applicability of each study were assessed with the Quality Assessment of Diagnostic Accuracy Studies-2 tool.

The delirium screening tool 4AT in routine clinical practice: prediction of mortality, sensitivity and specificity
Abstract: 
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.

Diagnostic accuracy of the 4AT for delirium detection in older adults: systematic review and meta-analysis
Abstract: 
OBJECTIVE: Detection of delirium in hospitalised older adults is recommended in national and international guidelines. The 4 'A's Test (4AT) is a short (<2 minutes) instrument for delirium detection that is used internationally as a standard tool in clinical practice. We performed a systematic review and meta-analysis of diagnostic test accuracy of the 4AT for delirium detection. 
METHODS: We searched MEDLINE, EMBASE, PsycINFO, CINAHL, clinicaltrials.gov and the Cochrane Central Register of Controlled Trials, from 2011 (year of 4AT release on the website www.the4AT.com) until 21 December 2019. Inclusion criteria were: older adults (≥65 years); diagnostic accuracy study of the 4AT index test when compared to delirium reference standard (standard diagnostic criteria or validated tool). Methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Pooled estimates of sensitivity and specificity were generated from a bivariate random effects model. 
RESULTS: Seventeen studies (3,702 observations) were included. Settings were acute medicine, surgery, a care home and the emergency department. Three studies assessed performance of the 4AT in stroke. The overall prevalence of delirium was 24.2% (95% CI 17.8-32.1%; range 10.5-61.9%). The pooled sensitivity was 0.88 (95% CI 0.80-0.93) and the pooled specificity was 0.88 (95% CI 0.82-0.92). Excluding the stroke studies, the pooled sensitivity was 0.86 (95% CI 0.77-0.92) and the pooled specificity was 0.89 (95% CI 0.83-0.93). The methodological quality of studies varied but was moderate to good overall. 
CONCLUSIONS: The 4AT shows good diagnostic test accuracy for delirium in the 17 available studies. These findings support its use in routine clinical practice in delirium detection. PROSPERO REGISTRATION NUMBER: CRD42019133702.

Diagnostic Test Accuracy of the 4AT for Delirium Detection: A Systematic Review and Meta-Analysis
Abstract: Under-recognition of delirium is an international problem. For the early detection of delirium, a feasible and valid screening tool for healthcare professionals is needed. This study aimed to present a scientific reason for using the 4 'A's Test (4AT) through a systematic review and meta-analysis of studies on the diagnostic test accuracy. We systematically searched articles in the EMBASE, MEDLINE, CINAHL, and PsycINFO databases and selected relevant articles on the basis of the predefined inclusion criteria. The quality of the included articles was evaluated using the Quality Assessment of the Diagnostic Accuracy Studies-2 tool. We estimated the pooled values of diagnostic test accuracy by employing the bivariate model and the hierarchical summary receiver operating characteristic (HSROC) model in data synthesis. A total of 3729 patients of 13 studies were included in the analysis. The pooled estimates of sensitivity and specificity of the 4AT were 81.5% (95% confidence interval: 70.7%, 89.0%) and 87.5% (79.5%, 92.7%), respectively. Given the 4AT's evidence of accuracy and practicality, we suggest healthcare professionals to utilize this tool for routine screening of delirium. However, for detecting delirium in the dementia population, further work is required to evaluate the 4AT with other cut-off points or scoring methods in order for it to be more sensitive and specific.

RADAR: A Measure of the Sixth Vital Sign?
Abstract: The objective of this study was to investigate the potential of RADAR (Recognizing Active Delirium As part of your Routine) as a measure of the sixth vital sign. This study was a secondary analysis of a study (N = 193) that took place in one acute care hospital and one long-term care facility. The primary outcome was a positive sixth vital sign, defined as the presence of both an altered level of consciousness and inattention. These indicators were assessed using the Confusion Assessment Method. RADAR identified 30 of the 43 participants as having a positive sixth vital sign and 58 of the 70 cases as not, yielding a sensitivity and specificity of 70% and 83%, respectively. Positive predictive value was 71%. RADAR's characteristics, including its brevity and acceptability by nursing staff, make this tool a good candidate as a measure of the sixth vital sign. Future studies should address the generalizability of RADAR among various populations and clinical settings.

Recognizing acute delirium as part of your routine [RADAR]: a validation study
Abstract: 
BACKGROUND: Although detection of delirium using the current tools is excellent in research settings, in routine clinical practice, this is not the case. Together with nursing staff, we developed a screening tool (RADAR) to address certain limitations of existing tools, notably administration time, ease-of-use and generalizability. The purpose of this study was not only to evaluate the validity and reliability of RADAR but also to gauge its acceptability among the nursing staff in two different clinical settings. 
METHODS: This was a validation study conducted on three units of an acute care hospital (medical, cardiology and coronary care) and five units of a long-term care facility. A total of 142 patients and 51 residents aged 65 and over, with or without dementia, participated in the study and 139 nurses were recruited and trained to use the RADAR tool. Data on each patient/resident was collected over a 12-hour period. The nursing staff and researchers administered RADAR during the scheduled distribution of medication. Researchers used the Confusion Assessment Method to determine the presence of delirium symptoms. Delirium itself was defined as meeting the criteria for DMS-IV-TR delirium. Inter-rater reliability, convergent, and concurrent validity of RADAR were assessed. At study end, 103 (74%) members of the nursing staff completed the RADAR feasibility and acceptability questionnaire. RESULTS: Percentages of agreement between RADAR items that bedside nurses administered and those research assistants administered varied from 82% to 98%. When compared with DSM-IV-TR criterion-defined delirium, RADAR had a sensitivity of 73% and a specificity of 67%. Participating nursing staff took about seven seconds on average, to complete the tool and it was very well received (≥98%) overall. 
CONCLUSIONS: The RADAR tool proved to be efficient, reliable, sensitive and very well accepted by nursing staff. Consequently, it becomes an appropriate new option for delirium screening among older adults, with or without cognitive impairment, in both hospitals and nursing homes. Further projects are currently underway to validate the RADAR among middle-aged adults, as well as in newer clinical settings; home care, emergency department, medical intensive care unit, and palliative care.
