RESUMEN
BACKGROUND: Malnutrition and sarcopenia significantly increase the risk of intra-hospital delirium, particularly among older adults. Given the potential correlation between calf circumference (CC) and these conditions, CC emerges as a promising predisposing factor for delirium. This study aims to investigate the independent association between delirium and anthropometric parameters, focusing on evaluating CC's predictive capacity for intra-hospital delirium risk. Additionally, it aims to compare CC's predictive performance with the widely used Mini Nutritional Assessment (MNA), while also considering potential gender disparities. METHODS: This is a retrospective study which enrolled patients aged ≥ 65 years from September 2021 to March 2022 at the Padova Hospital (Italy). Physical characteristics, intra-hospital delirium incidence, and body composition were assessed. Sarcopenia was diagnosed using the 2019 European Consensus criteria. RESULTS: Among 207 subjects, delirium affected 19% of patients. CC showed a significant association with intra-hospital delirium among the analyzed anthropometric parameters. ROC curves indicated that CC's predictive capacity for delirium onset was comparable to MNA (p = 0.98), particularly in women. In a multivariable logistic regression model, female gender and higher cognitive and CC scores emerged as protective factors against delirium onset, with each unit increase in CC associated with a 24% reduction in the odds of delirium. Conversely, sarcopenia did not significantly influence delirium onset. CONCLUSIONS: CC shows promise as a predisposing factor for intra-hospital delirium, similar to MNA, albeit with significant gender differences. CC could serve as a valuable tool for assessing delirium risk among female patients. Further validation of these findings is necessary through larger-scale studies.

OBJECTIVE: To explore the predictive value of leukocyte derived markers for postoperative delirium (POD) in patients undergoing cardiac valve surgery. METHODS: A prospective cohort study was conducted. The patients who underwent cardiac valve surgery admitted to Beijing Anzhen Hospital of Capital Medical University from October 2021 to March 2023 were enrolled. The demographic, baseline and perioperative data were collected, and the neutrophil to lymphocyte ratio (NLR) and platelet to white blood cell ratio (PWR) were calculated before operation and within 24 hours after operation. Delirium assessment was conducted twice a day for patients within 1-5 days after surgery or discharged within 5 days. According to the evaluation results, the patients were divided into delirium group and non-delirium group. The clinical indexes between the two groups were compared. Multivariate Logistic regression analysis was used to screen the independent risk factors of POD, and the POD predictive model was constructed. The predictive value of POD predictive model was evaluated by receiver operator characteristic curve (ROC curve). RESULTS: A total of 235 patients were enrolled in the analysis, of which 83 patients had POD (35.32%) and 152 patients did not have POD (64.68%). Compared with the non-delirious group, the patients in the delirious group had higher Charlson comorbidity index (CCI) score and lower mini-mental state examination (MMSE) score. In terms of perioperative data, compared with the non-delirium group, the patients in the delirium group had longer operative time, duration of cardiopulmonary bypass, length of intensive care unit (ICU) stay, duration of mechanical ventilation, and postoperative hospital stay, higher incidence of perioperative atrial fibrillation, and lower discharge life score. In terms of leukocyte derived markers, NLR within 24 hours after surgery in both groups were significantly higher than those before surgery, and PWR were significantly lower than those before surgery. The NLR within 24 hours after surgery, PWR difference and NLR difference in the delirium group were significantly higher than those in the non-delirium group. Multivariate Logistic regression analysis showed that CCI score [odds ratio (OR) = 1.394, 95% confidence interval (95%CI) was 1.038-1.872, P = 0.027], perioperative atrial fibrillation (OR = 3.697, 95%CI was 1.711-7.990, P < 0.001), duration of cardiopulmonary bypass (OR = 1.008, 95%CI was 1.002-1.015, P = 0.016), length of ICU stay (OR = 1.006, 95%CI was 1.002-1.010, P = 0.002), NLR difference (OR = 1.029, 95%CI was 1.009-1.050, P = 0.005) and PWR difference (OR = 1.044, 95%CI was 1.009-1.080, P = 0.013) were independently correlated with POD. POD predictive model was constructed by multivariate Logistic regression analysis result: POD predictive model index = -4.970+0.336×CCI score+1.317×perioperative atrial fibrillation+0.009×duration of cardiopulmonary bypass+0.006×length of ICU stay+0.030×NLR difference+0.044×PWR difference. ROC curve analysis showed that the area under the ROC curve (AUC) of NLR difference for predicting POD was 0.659 (95%CI was 0.583-0.735), the optimal critical value was 16.62, the sensitivity was 60.2%, and the specificity was 70.4% (P < 0.05). The AUC of PWR difference for predicting POD was 0.608 (95%CI was 0.528-0.688), the optimal critical value was 25.68, the sensitivity was 51.8%, and the specificity was 75.7% (P < 0.05). The AUC of POD predictive model for predicting POD was 0.805 (95%CI was 0.745-0.865), the optimal critical value was 0.39, the sensitivity was 74.7%, and the specificity was 79.6% (P < 0.05). CONCLUSIONS: The differences of NLR and PWR are independently related to POD, which has potential value in predicting POD after cardiac valve surgery.

Iron metabolism disorder has been identified as a contributor to the pathogenesis and progression of multiple cognitive dysfunction-related diseases, including postoperative delirium. However, the association between preoperative iron reserves and postoperative delirium risk remains elusive. This retrospective cohort study aimed to explore the impact of preoperative serum ferritin levels on the risk of postoperative delirium in elderly patients undergoing non-neurosurgical and non-cardiac procedures. Conducted at the Chinese PLA General Hospital between January 2014 and December 2021, the study finally included 12,841 patients aged 65 years and above. Preoperative serum ferritin levels were assessed within 30 days before surgery, and postoperative delirium occurrence within the first seven days after surgery was determined through medical chart review. The analyses revealed that both low and high levels of serum ferritin were associated with an increased risk of postoperative delirium. Patients in the lowest quintile of serum ferritin exhibited an 81% increased risk, while those in the highest quintile faced a 91% increased risk compared to those in the second quintile. Furthermore, mediation analyses indicated that the direct effect of preoperative serum ferritin on postoperative delirium contradicted its indirect effect mediated by hemoglobin levels. These findings suggest that maintaining serum ferritin within moderate range preoperatively could be beneficial for managing postoperative delirium risk among elderly patients.

OBJECTIVES: To review current evidence on using the geriatric nutritional risk index (GNRI) in predicting postoperative delirium (POD) in elderly patients. METHODS: The literature search was performed in core databases to include all the cohort studies on the association between GNRI and risk of POD for further meta-analysis. RESULTS: A total of 6 studies with 4242 patients underwent this meta-analysis, which showed that the risk of POD was higher in patients with moderate and high GNRI than the ones with low GNRI (odds ratio [OR]=2.04, 95% confidence interval [CI] [1.58, 2.64], p<0.001), and moderate and high GNRI significantly increased the risk of POD in patients of 60 to 75 years or above [OR=1.98, 95%CI (1.49, 2.62), p<0.001; OR=2.79, 95%CI (1.38, 5.64), p=0.004, respectively]. CONCLUSION: Therefore, moderate and high GNRI increased the risk of POD in elderly patients.

BACKGROUND: Postoperative delirium (POD) is a serious and common complication. The aim of present study is to investigate the diurnal variation of POD and the effects of esketamine in elderly patients. METHODS: A randomized, double-blind, placebo-controlled clinical trial with factorial design was conducted. Patients (aged 65 to 85 years) with normal Mini-Mental State Examination (MMSE) score were stratified by age (≤70 vs. >70) and American Society of Anesthesiologists physical status classification (â ¡ vs. â ¢), then randomly assigned to either morning (08:00-12:00) or afternoon (14:00-18:00) noncardiac operation under general anesthesia with or without esketamine administration (0.2 mg/kg). The primary outcome was the incidence of POD (3-Minute Diagnostic Interview for Confusion Assessment Method-defined Delirium, 3D-CAM) on postoperative days 1, 3, and 7. The secondary outcomes were the scores of MMSE and Hospital Anxiety and Depression Scale. The intention-to-treat analysis of the outcomes were performed by generalized estimating equation. RESULTS: Six patients who did not receive an intervention because of canceled operation were excluded after randomization. The datasets containing 426 cases were analyzed following the intention-to-treat principle after handling missing data via multiple imputation method. The incidence of POD declined from about 55% on postoperative day 1 to 31 and 18% on postoperative days 3 and 7, respectively. Afternoon operation [B=-0.583, OR (95% CI) 0.558 (0.319-0.976); P=0.041], but not esketamine, significantly decreased the incidence of POD. Both esketamine and operation time failed to significantly affect MMSE, HAD, and NRS score. There was no interaction among operation time, esketamine, and follow up time. CONCLUSION: Elderly patients undergoing elective noncardiac surgery in the afternoon displayed lower POD incidence than those operated in the morning. A single low-dose of esketamine before general anesthesia induction failed to significantly decrease the risk of POD but decrease the risk of intraoperative hypotension and emergence agitation.

To investigate effectiveness of the ABCDEF bundle to manage and prevent delirium. BACKGROUND: ICU delirium is a common hospital problem that 80% of critically ill patients in the ICU experience. The ABCDEF bundle is one of the tools that included in Delirium guidelines to manage critically ill patients. RESEARCH DESIGN: Pre- and post intervention a quasi-experimental design was utilized in the present study. SETTING: This study was conducted in the intensive care units of Assiut University Hospital. METHODS: A total of 60 mechanically ventilated patients were recruited using inclusion and exclusion criteria. The ABCDEF bundle was implemented every day for the first 7 days of ICU admission, and patient sedation and delirium status were assessed using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). Sedation instrument measures were utilized in data collection. RESULTS: Significant differences were found in the incidence of delirium: 20% in the study group versus 70% in the control group. The increased mean of days without delirium ICU stay was 4.6333 in the study group and 1.1000 in the control group, with P value = .001. CONCLUSION: The mechanically ventilated patients exposed to the implementation of the ABCDE bundle experienced fewer delirium signs than before the ABCDE bundle was implemented.

OBJECTIVE: The surgical population is ageing and often frail. Frailty increases the risk for poor post-operative outcomes such as delirium, which carries significant morbidity, mortality and cost. Frailty is often measured in a binary manner, limiting pre-operative counselling. The goal of this study was to determine the relationship between categorical frailty severity level and post-operative delirium. METHODS: We performed an analysis of a retrospective cohort of older adults from 12 January 2018 to 3 January 2020 admitted to a tertiary medical center for elective surgery. All participants underwent frailty screening prior to inpatient elective surgery with at least two post-operative delirium assessments. Planned ICU admissions were excluded. Procedures were risk-stratified by the Operative Stress Score (OSS). Categorical frailty severity level (Not Frail, Mild, Moderate, and Severe Frailty) was measured using the Edmonton Frail Scale. Delirium was determined using the 4 A's Test and Confusion Assessment Method-Intensive Care Unit. RESULTS: In sum, 324 patients were included. The overall post-operative delirium incidence was 4.6% (15 individuals), which increased significantly as the categorical frailty severity level increased (2% not frail, 6% mild frailty, 23% moderate frailty; P < 0.001) corresponding to increasing odds of delirium (OR 2.57 [0.62, 10.66] mild vs. not frail; OR 12.10 [3.57, 40.99] moderate vs. not frail). CONCLUSIONS: Incidence of post-operative delirium increases as categorical frailty severity level increases. This suggests that frailty severity should be considered when counselling older adults about their risk for post-operative delirium prior to surgery.

Delirium has long been recognized within the adult intensive care world, but it is only within the past decade that its presence and prevalence in the context of pediatric intensive care has been studied. There is now a greater understanding of risk factors for delirium, a better selection of methods to recognize it, and treatment specifically directed to pediatric patients. An understanding of delirium is also relevant to pediatricians practicing outside of the intensive care unit, as delirium can present in other care environments, where it remains under-recognized. The purpose of this article is to review pediatric delirium by discussing its pathophysiology, the tools available to screen patients, and current prevention and management approaches.

PURPOSE: Despite the importance of measuring delirium severity in patients with Alzheimer's disease and related dementias (ADRD), no validated instrument currently exists. Our goal was to generate items for use in such an instrument. METHOD: An interdisciplinary expert panel developed items to assess seven domains and 21 subdomains of delirium severity. Nursing experts provided input on items. RESULTS: Experts achieved consensus on 21 items, including best respondents for each item, and appropriate look-back periods. Nursing experts emphasized the need for educating nursing staff and obtaining information from caregivers. CONCLUSION: Careful, nuanced identification of distinguishing features is key for generating items for measuring delirium severity in persons with ADRD. Once developed, engaging nurses will be essential to facilitate adoption and relevance of the tool. [Journal of Gerontological Nursing, 50(9), 24-30.].

ABSTRACT: BACKGROUND: Delirium is a common complication during hospitalization. Its consequences are severe, including reduced function, delayed rehabilitation, dementia, institutionalization, and death. Assessing delirium in neurological patients can be challenging due to the impact of neurological deficits. Therefore, the aim was to investigate the agreement between 2 delirium screening tools, factors associated with delirium, and assessing delirium in neurological patients. METHODS: This prospective observational study was conducted in 2 neurological units, using daily delirium screening. Intensive Care Delirium Screening Checklist and 2 versions of the Confusion Assessment Method were used to asses delirium in adult patients without baseline dementia, alcohol/drug detoxification, or palliative care. Descriptive analyses determined the number of delirium scores, and the analytical analyses were logistic regressions and a κ coefficient. RESULTS: The agreement between the screening tools was found to be substantial (κ = 0.71). Logistic regression analysis showed that the risk factors for a positive delirium screening were home care before admission (Confusion Assessment Method: odds ratio [OR], 4.21 [95% confidence interval (CI), 1.67-10.63]; Intensive Care Delirium Screening Checklist: OR, 6.14 [95% CI, 2.85-13.23]) and aphasia/dysarthria (Confusion Assessment Method: OR, 4.9 [95% CI, 1.32-6.81]; Intensive Care Delirium Screening Checklist: OR, 2.76 [95% CI, 1.3-5.87]). In total, 18.7% (n = 20/107) of the screening scores were positive. Specifically, the Confusion Assessment Method showed positive scores for 13.0% (n = 14/107) of participants, whereas the Intensive Care Delirium Screening Checklist showed positive scores for 16.8% (n = 18/107). CONCLUSION: The screening tools had a substantial degree of agreement. Therefore, nurses can use both screening tools to detect delirium in patients with neurological disorders. However, care should be taken in patients with aphasia to avoid misclassification with the Brief-Confusion Assessment Method. Moreover, special attention should be directed toward patients with language difficulties such as aphasia/dysarthria and those who received home care services before admission. These areas warrant further investigation in clinical practice and future studies.

OBJECTIVE: Validations of brief delirium tools have not included analysis of psychiatric disorders comorbidities or control groups. We validated the Delirium Diagnostic Tool-Provisional (DDT-Pro) in 422 geriatric inpatients with high incidence of depression and/or dementia. METHODS: Cross-sectional study using two delirium reference standards, DSM-5-TR and Delirium Rating Scale-Revised-98 (DRS-R98). We assessed concurrent and construct DDT-Pro validity too. RESULTS: There were 117 (27.7%) delirium cases using DDT-Pro, 104 (24.6%) per DSM-5-TR and 93 (22.0%) per DRS-R98; 133 patients (31.5%) had depression and 105 (24.9%) dementia, some comorbid with delirium. DDT-Pro accuracy (AUC under ROC curve) ranges were 88.3-95.9% vs DSM-5-TR and 92.7-95.0% vs DRS-R98 for whole sample and four diagnostic groups, without statistical differences. DDT-Pro ≤6 had the most balanced sensitivity-specificity for delirium diagnosis against both DSM-5-TR and DRS-R98 with similar specificity but higher sensitivity for DRS-R98 than DSM-5-TR delirium, with the highest values in patients with depression and dementia (≥92% sensitivity, ≥81% specificity). Positive and negative likelihood ratios support diagnostic strength. Concurrent validity was high reflected by significant correlations (p < 0.001) of DDT-Pro total and item scores with DRS-R98 and Delirium Frontal Index scores, highest in groups with comorbid depression and/or dementia. The DDT-Pro represented a single construct for delirium demonstrated by one factor with high item loadings and high internal consistency reliability of its items. CONCLUSIONS: The DDT-Pro demonstrated strong performance metrics in general hospital elderly inpatients with preexisting depression and/or dementia, which is unique among brief delirium tools. Its optimized cutoff score was the same as in other populations.

Aim: To reveal factors affecting 2-year mortality in geriatric patients hospitalized with COVID-19.Methods: Demographic characteristics, clinical and laboratory data, thorax computed tomography (CT) images, second-year survival status, and causes of death were analyzed.Results: The 2-year post-discharge mortality rate of 605 patients was 21.9%. Mean age of patients in the deceased group was 76.8 ± 8.1 years, which was shorter than the life expectancy at birth in Türkiye. Older age (≥85), delirium, some co-morbidities, and atypical thorax CT involvement were associated with a significant increase in 2-year mortality (p < 0.05).Conclusion: This is the first study to evaluate factors associated with 2-year mortality in older COVID-19 patients. Identifying risk factors for long-term mortality in geriatric COVID-19 patients is important.

OBJECTIVES: To evaluate the duration of subsyndromal delirium (SSD) in intensive care unit (ICU) patients and the factors associated with SSD duration. METHODS: This retrospective study included adult patients admitted to the ICU of Affiliated Hospital of Nantong University between December 2019 and June 2020. All patients with Richmond Agitation Sedation Scale scores of ≥-2 were evaluated every 8 h using the confusion assessment method of the intensive care unit (CAM-ICU) until the patients with SSD were negative, progressed to delirium, fell into a coma, died, or were discharged from the ICU. Multivariable Cox regression analyses were performed to determine the factors associated with SSD duration. RESULTS: Of the 388 patients, 53.6% had SSD, and 20.7% progressed from SSD to delirium. The duration of SSD ranged from 8 to 248 h, and the median duration was 48 h (interquartile range, 24-72). Age (hazard ratio [HR] = 0.985, 95% confidence interval [CI], 0.971-0.999, p = 0.035), surgery or not (HR = 0.514; 95% CI, 0.310-0.850; p = 0.010), duration of ventilation (HR = 1.003; 95% CI, 1.000-1.006; p = 0.044), duration of hypoxia (HR = 0.212; 95% CI, 0.103-0.438; p < 0.001), and adapted cognitive exam scores (HR = 1.057; 95% CI, 1.030-1.085; p < 0.001) were independently associated with the duration of SSD. CONCLUSIONS: The duration of SSD was associated with age, surgery, duration of ventilation, duration of hypoxia, and cognitive function. SSD has a high incidence among ICU patients, and many patients progress to delirium. PATIENT OR PUBLIC CONTRIBUTION: The study team met with public members of the evaluation teams throughout the project in a series of workshops. Workshops informed study design, data collection tools and data interpretation. RELEVANCE TO CLINICAL PRACTICE: ICU staff should pay attention to SSD patients with older age, history of surgery, longer duration of ventilation, prolonged duration of hypoxia, and lower ACE scores.

BACKGROUND: The Valve Academic Research Consortium (VARC)-3 definition for neurologic events after transcatheter aortic valve replacement (TAVR) lacks clinical validation. OBJECTIVES: This study sought to determine the incidence, predictors, and clinical impact of neurologic events following TAVR as defined by VARC-3 criteria. METHODS: This was a multicenter study including 2,924 patients with severe aortic stenosis undergoing TAVR. Based on Neurologic Academic Research Consortium (NeuroARC) classification, neurologic events were classified as NeuroARC type 1 (stroke), NeuroARC type 2 (covert central nervous system injury), and NeuroARC type 3 (transient ischemic attack and delirium). Baseline, procedural, and follow-up data were prospectively collected in a dedicated database. RESULTS: After a median follow-up of 13 (7-37) months, neurologic events occurred in 471 patients (16.1%), NeuroARC type 1, 2, and 3 in 37.4%, 4.7%, and 58.0% of cases, respectively, and the majority (58.6%) were periprocedural. Advanced age, chronic kidney disease, atrial fibrillation, major vascular complications, and in-hospital bleeding determined an increased risk of periprocedural events (P < 0.03 for all). Neurologic events occurring during the periprocedural time frame were independently associated with a substantial increase in mortality at 1 year after the intervention (HR: 1.91; 95% CI: 1.23-2.97; P = 0.004). However, although NeuroARC type 1 was associated with an increased mortality risk (IRR: 3.38; 95% CI: 2.30-5.56; P < 0.001 and IRR: 21.7; 95% CI: 9.63-49.1; P < 0.001 for ischemic and hemorrhagic stroke, respectively), the occurrence of NeuroARC type 3 events had no impact on mortality. CONCLUSIONS: Neurologic events after TAVR were associated with poorer short- and long-term survival. This correlation was related to the type of NeuroARC event defined by the VARC-3 criteria. Given the negative impact on clinical outcomes, every attempt should be made to reduce the risk of neurologic complications after TAVR.

Research on the severity and prognosis of sepsis with or without progressive delirium is relatively insufficient. We constructed a prediction model of the risk factors for 28-day mortality in patients who developed sepsis or sepsis-associated delirium. The modeling group of patients diagnosed with Sepsis-3 and patients with progressive delirium of related indicators were selected from the MIMIC-IV database. Relevant independent risk factors were determined and integrated into the prediction model. Receiver operating characteristic (ROC) curves and the Hosmer-Lemeshow (HL) test were used to evaluate the prediction accuracy and goodness-of-fit of the model. Relevant indicators of patients with sepsis or progressive delirium admitted to the intensive care unit (ICU) of a 3A hospital in Xinjiang were collected and included in the verification group for comparative analysis and clinical validation of the prediction model. The total length of stay in the ICU, hemoglobin levels, albumin levels, activated partial thrombin time, and total bilirubin level were the five independent risk factors in constructing a prediction model. The area under the ROC curve of the predictive model (0.904) and the HL test result (χ2 = 8.518) indicate a good fit. This model is valuable for clinical diagnosis and treatment and auxiliary clinical decision-making.

The visual attentional deficits in delirium are poorly characterized. Studies have highlighted neuro-anatomical abnormalities in the visual processing stream but fail at quantifying these abnormalities at a functional level. To identify these deficits, we undertook a multi-center eye-tracking study where we recorded 210 sessions from 42 patients using a novel eye-tracking system that was made specifically for free-viewing in the (ICU); each session lasted 10 min and was labeled with the delirium status of the patient using the Confusion Assessment Method in ICU (CAM-ICU). To analyze this data, we formulate the task of visual attention as a hierarchical generative process that yields a probabilistic distribution of the location of the next fixation. This distribution can then be compared to the measured patient fixation producing a correctness score which is tallied compared across delirium status. This analysis demonstrated that the visual processing system of patients suffering from delirium is functionally restricted to a statistically significant degree. This is the first study to explore the potential mechanisms underpinning visual inattention in delirium and suggests a new target of future research into a disease process that affects one in four hospitalized patients with severe short and long-term consequences.

BACKGROUND: Delirium is a common complication in intensive care unit (ICU) patients. It can lead to various adverse events. In this study, we investigated the effectiveness of combining the use of the PREdiction of DELIRium (PRE-DELIRIC) model for delirium risk assessment and the use of a multicomponent care bundle for delirium assessment, prevention, and care in terms of reductions in the incidence of delirium among surgical ICU patients. METHODS: This retrospective study included surgical ICU patients who had received PRE-DELIRIC-guided SMART/SmART care (SMART care: SmART bundle plus multidisciplinary team; SmART care: Sleep/sweet sense of home (creating a comforting and restful environment for patients), Assessment (regular and thorough evaluation of patient needs and conditions), Release (revised endotracheal tube care/removal, restraint device care, and immobility reduction for patient comfort), and Time (reorientation of time to optimize patient care schedules) in our hospital between May 2022 and March 2023 (intervention group) and individuals who had received usual care between January 2021 and April 2022 (historical control group). The SmART intervention involves providing care in the following domains: sleep/sweet sense of home, assessment, release, and time. Patients with a PRE-DELIRIC score of >30% received SMART care, which includes multidisciplinary (physicians, pharmacists, respiratory therapists, and physiotherapists) care in addition to SmART care. For the control group, usual care was provided following the guidelines for the prevention and management of pain, agitation, delirium, immobility, and sleep disruption. The primary outcome was delirium incidence during ICU stay, which was assessed using the Intensive Care Delirium Screening Checklist. The secondary outcomes were the duration of ICU stay, rate of unplanned self-extubation, and status of ICU discharge. RESULTS: The intervention and control groups comprised 184 and 197 patients, respectively; their mean ages were 63.7 ± 18.4 years and 62.4 ± 19.5 years, respectively. The incidence of delirium was significantly lower (p = 0.001) in the intervention group (22.3%) than in the control group (47.7%). CONCLUSION: Our findings suggest that the PRE-DELIRIC-guided SMART/SmART care intervention is effective in preventing and managing delirium among surgical ICU patients.

STUDY OBJECTIVE: To determine the diagnostic accuracy of the Montreal Cognitive Assessment (MoCA) in detecting cognitive impairment (CI) and assess the association of MoCA scores with adverse postoperative outcomes in surgical populations. DESIGN: Systematic review and meta-analysis. SETTING: Perioperative setting. PATIENTS: Adults undergoing elective or emergent surgery screened for CI preoperatively using the MoCA. MEASUREMENTS: The outcomes included the diagnostic accuracy of the MoCA in screening for CI and the pooled prevalence of CI in various surgical populations. CI and its association with adverse events including delirium, hospital length-of-stay (LOS), postoperative complications, discharge destination, and mortality was determined. MAIN RESULTS: Twenty-six studies (5059 patients, 18 non-cardiac studies, 8 cardiac studies) were included. With a MoCA cut-off score of <26, the prevalence of preoperative CI was 48% (95% CI: 41%-54%). The MoCA had 0.87 (95% CI: 0.79-0.93) sensitivity, 0.72 (95% CI: 0.62-0.80) specificity, PPV of 0.74 (95% CI: 0.65-0.81), and NPV of 0.86 (95% CI: 0.77-0.92) when validated against Petersen criteria, the Diagnostic and Statistical Manual of Mental Disorders, or the National Institute on Aging and the Alzheimer's Association criteria to identify CI. Using the MoCA as a screening tool, the LOS was 3.75 (95% CI: -0.03-7.53, P = 0.05, not significant) days longer in the CI group after non-cardiac surgeries and 3.33 (95% CI: 1.24-5.41, P < 0.002) days longer after cardiac surgeries than the non-cognitively impaired group. CONCLUSIONS: MoCA had been validated in the surgical population. MoCA with a cut-off score of <26 was shown to have 87% sensitivity and 72% specificity in identifying CI. A positive screen in MoCA was associated with a 3-day longer hospital LOS in cardiac surgery in the CI group than in the non-CI group.

BACKGROUND: Delirium is a common complication of older people in hospitals, rehabilitation and long-term facilities. OBJECTIVE: To assess the worldwide use of validated delirium assessment tools and the presence of delirium management protocols. DESIGN: Secondary analysis of a worldwide one-day point prevalence study on World Delirium Awareness Day, 15 March 2023. SETTING: Cross-sectional online survey including hospitals, rehabilitation and long-term facilities. METHODS: Participating clinicians reported data on delirium, the presence of protocols, delirium assessments, delirium-awareness interventions, non-pharmacological and pharmacological interventions, and ward/unit-specific barriers. RESULTS: Data from 44 countries, 1664 wards/units and 36 048 patients were analysed. Validated delirium assessments were used in 66.7% (n = 1110) of wards/units, 18.6% (n = 310) used personal judgement or no assessment, and 10% (n = 166) used other assessment methods. A delirium management protocol was reported in 66.8% (n = 1094) of wards/units. The presence of protocols for delirium management varied across continents, ranging from 21.6% (on 21/97 wards/units) in Africa to 90.4% (235/260) in Australia, similar to the use of validated delirium assessments with 29.6% (29/98) in Africa to 93.5% (116/124) in North America. Wards/units with a delirium management protocol [n = 1094/1664, 66.8%] were more likely to use a validated delirium test than those without a protocol [odds ratio 6.97 (95% confidence interval 5.289-9.185)]. The presence of a delirium protocol increased the chances for valid delirium assessment and, likely, evidence-based interventions. CONCLUSION: Wards/units that reported the presence of delirium management protocols had a higher probability of using validated delirium assessments tools to assess for delirium.
