Abstract
PURPOSE Adequate pain management is eminently relevant for elderly and more vulnerable patients with hip fractures in the setting of pre and postoperative pain. This study compares postoperative hip fracture patients treated with standard pain management with a variety of medications or an approach with only one option in each medication category (nonopioid: acetaminophen; opioid: fentanyl TTS 12,5 mcg/hour; rescue medication: piritramide) to simplify the treatment algorithm for nurses and improve patient well-being. DESIGN Double-blind randomized controlled trial. METHODS The sample was cognitively intact patients (N = 141) with hip fractures in a tertiary university hospital. Administration of fentanyl 12 mcg/hour transdermal therapeutic system was administered by the nurses in the postanesthesia care unit (PACU) to address basal wound pain to improve patient well-being and patient treatment in the PACU for 24 hours to better control for early complications. FINDINGS Well-being was equally increased in both groups in comparison to our preintervention data from 35.7% to over 60% and did not differ significantly between the intervention and control group. No statistically significant differences in numeric rating scale scores, rescue opioid dosage (piritramide i.v.) or in complications were present. CONCLUSIONS This one-size-fits-all simplified pain management approach did not improve patient well-being or any other outcome but highlighted the importance of adequate pain management and a sufficient nurse-to-patient ratio.

Abstract
Aims and background The efficacy of dexmedetomidine and propofol in preventing postoperative delirium is controversial. This study aims to evaluate the efficacy of dexmedetomidine and propofol for preventing postoperative delirium in extubated elderly patients undergoing hip fracture surgery. Materials and methods This randomized controlled trial included participants undergoing hip fracture surgery. Participants were randomly assigned to receive dexmedetomidine, propofol, or placebo intravenously during intensive care unit (ICU) admission (8 p.m. to 6 a.m.). The drug dosages were adjusted to achieve the Richmond Agitation Sedation Scale (RASS) of 0 to -1. The primary outcome was postoperative delirium. The secondary outcomes were postoperative complications, fentanyl consumption, and length of hospital stay. Results 108 participants were enrolled (n = 36 per group). Postoperative delirium incidences were 8.3%, 22.2%, and 5.6% in the dexmedetomidine, propofol, and placebo groups, respectively. The hazard ratios of dexmedetomidine and propofol compared with placebo were 1.49 (95% CI, 0.25, 8.95; p = 0.66) and 4.18 (95% CI, 0.88, 19.69; p = 0.07). The incidence of bradycardia was higher in the dexmedetomidine group compared with others (13.9%; p = 0.01) but not for hypotension (8.3%; p = 0.32). The median length of hospital stays (8 days, IQR: 7, 11) and fentanyl consumption (240 µg, IQR: 120, 400) were not different among groups. Conclusion This study did not successfully demonstrate the impact of nocturnal low-dose dexmedetomidine and propofol in preventing postoperative delirium among elderly patients undergoing hip fracture surgery. While not statistically significant, it is noteworthy that propofol exhibited a comparatively higher delirium rate.

Abstract
INTRODUCTION The effect of spinal versus general anesthesia on the risk of postoperative delirium or other outcomes for patients with or without cognitive impairment (including dementia) is unknown. METHODS Post hoc secondary analysis of a multicenter pragmatic trial comparing spinal versus general anesthesia for adults aged 50 years or older undergoing hip fracture surgery. RESULTS Among patients randomized to spinal versus general anesthesia, new or worsened delirium occurred in 100/295 (33.9%) versus 107/283 (37.8%; odds ratio [OR] 0.85; 95% confidence interval [CI] 0.60 to 1.19) among persons with cognitive impairment and 70/432 (16.2%) versus 71/445 (16.0%) among persons without cognitive impairment (OR 1.02; 95% CI 0.71 to 1.47, p = 0.46 for interaction). Delirium severity, in-hospital complications, and 60-day functional recovery did not differ by anesthesia type in patients with or without cognitive impairment. DISCUSSION Anesthesia type is not associated with differences in delirium and functional outcomes among persons with or without cognitive impairment.

Abstract
Purpose The primary aim of this study was to identify risk factors for delirium after hip fracture surgery. The secondary purpose of this study was to verify peri-operative clinical outcomes, adverse events and mortality rates in delirium patients after hip fracture surgery. Patients and Methods A prospective hip fracture database was used to obtain data. In total, 2051 patients older than 70 years undergoing a hip fracture surgery between 01-01-2018 and 01-01-2021 were included. A delirium was diagnosed by a geriatrician based on the DSM-V criteria. Results The results showed that 16% developed a delirium during hospital admission. Multivariable analysis showed that male gender (OR: 1.99, p<0.001), age (OR: 1.06, p<0.001), dementia (OR: 1.66, p=0.001), Parkinson's disease (OR: 2.32, p=0.001), Δhaemoglobin loss (OR: 1.19, p=0.022), pneumonia (OR: 3.86, p<0.001), urinary tract infection (UTI) (OR: 1.97, p=0.001) and wound infection (OR: 3.02, p=0.007) were significant independent prognostic risk factors for the development of a delirium after hip surgery. The median length in-hospital stay was longer in patients with a delirium (9 days) vs patients without a delirium (6 days) (p<0.001). The 30-day mortality was 7% (with delirium 16% vs with no delirium 6% (p<0.001)). Conclusion Significant independent prognostic factors associated with delirium after hip surgery were male gender, age, dementia, Parkinson's disease, Δhaemoglobin loss, pneumonia, UTI and wound infection.

Abstract
BACKGROUND There is limited evidence regarding predictors of functional trajectories after hip fracture. We aimed to identify groups with different trajectories of functional recovery the first year after hip fracture, and to determine predictors for belonging to such groups. METHODS This longitudinal study combined data from two large randomized controlled trials including patients with hip fracture. Participants were assessed at baseline, four and 12 months. We used the Nottingham Extended Activities of Daily Living (NEADL) as a measure of instrumental ADL (iADL) and Barthel Index for personal ADL (pADL). A growth mixture model was estimated to identify groups of patients following distinct trajectories of functioning. Baseline characteristics potentially predicting group-belonging were assessed by multiple nominal regression. RESULTS Among 726 participants (mean age 83.0; 74.7% women), we identified four groups of patients following distinct ADL trajectories. None of the groups regained their pre-fracture ADL. For one of the groups identified in both ADL outcomes, a steep decline in function was shown the first four months after surgery, and none of the groups showed functional recovery between four and 12 months after surgery. CONCLUSIONS No groups regained their pre-fracture ADL. Some of the patients with relatively high pre-fracture function, had a steep ADL decline. For this group there is a potential for recovery, but more knowledge and research is needed in this group. These findings could be useful in uncovering groups of patients with different functioning after a hip fracture, and aid in discharge planning.

Abstract
Additional variables for a nationwide hip fracture registry must be carefully chosen to prevent unnecessary registry load. A registry pilot in seven hospitals resulted in recommending polypharmacy, serum hemoglobin at admittance, and questions screening for risk of delirium to be used in case-mix correction and for development of quality indicators. PURPOSE Clinical registries help improve the quality of care but come at the cost of registration load. Datasets should therefore be as compact as possible; however, variables are usually chosen empirically. This study aims to evaluate potential variables with additional value to improve the nationwide Dutch Hip Fracture Audit (DHFA). METHODS An expert panel selected eleven new variables for the DHFA, which were tested in a prospective cohort of all hip fracture patients treated in 2018 and 2019 in seven pilot hospitals participating in the DHFA. The association of these eleven variables with complications, mortality, and functional outcomes at 3 months was analyzed using multivariable logistic regression analysis. Based on the results, a proposal for variables to add to the dataset of the DHFA was made. RESULTS In 4.904 analyzed patients, three tested variables had significant associations (p < 0.01) with outcomes: polypharmacy with complications (aOR 1.34), serum hemoglobin at admittance with complications (aOR 0.63) and mortality (aOR for 30-day mortality 0.78), and a set of questions screening for risk of delirium with complications in general (aOR 1.55), e.g., delirium (aOR 2.98), and decreased functional scores at three months (aOR 1.98). CONCLUSION This study assesses potential new variables for a hip fracture registry. Based on the results of this study, we recommend polypharmacy, serum hemoglobin at admittance, and questions screening for risk of delirium to be used in case-mix correction and for the development of quality indicators. Incorporating these variables in the DHFA dataset may contribute to better and clinically relevant quality indicators.

Abstract
Background Frail older persons with cognitive impairment (CI) are at special risk of experiencing delirium during acute hospitalisation. The purpose of this study was to investigate whether a dementia-friendly hospital program contributes to improved detection and management of patients with CI and risk of delirium at an acute-care hospital in Norway. Furthermore, we aimed to explore whether the program affected the detection of delirium, pharmacological treatment, 30-day re-hospitalisation, 30-day mortality and institutionalisation afterwards. Methods This study was part of a larger quality improvement project aiming at developing and implementing a new program for early screening and management of patients with CI. This study, evaluating the program are designed as a controlled clinical trial with a historical control group. It was conducted at two different medical wards at a large acute-care hospital in Norway from September 2018 to December 2019. A total of 423 acute hospitalised patients 75 years of age or older were included in the study. Delirium screening and cognitive tests were recorded by research staff with the 4 ‘A’s Test (4AT) and the Confusion Assessment Measure (CAM), while demographic and medical information was recorded from the electronic medical records (EMR). Results Implementation of the dementia-friendly hospital program did not show any significant changes in the identification of patients with CI. However, the share of patients screened with 4AT within 24 h increased from 0% to 35.5% (P < .001). The proportion of the patients with CI identified by the clinical staff, who received measures to promote “dementia-friendly” care and reduce the risk for delirium increased by 32.2% (P < .001), compared to the control group. Furthermore, the number of patients with CI who were prescribed antipsychotic, hypnotic or sedative medications was reduced by 24.5% (P < .001). There were no differences in delirium detection, 30-day readmission or 30-day mortality. Conclusions A model for early screening and multifactorial non-pharmacological interventions for patients with CI and delirium may improve management of this patient group, and reduce prescriptions of antipsychotic, hypnotic and sedative medications. The implementation in clinical practice of early screening using quality improvement methodology deserves attention. Trial registration The protocol of this study was retrospectively registered in the ClinicalTrials.gov Protocol Registration and Results System with the registration number: NCT04737733 and date of registration: 03/02/2021.

Abstract
Background: In patients with Alzheimer’s disease (AD), bacterial infections are often associated with a cognitive decline. Animal models of genuine acute infections with viable bacteria which induce deterioration of neurodegenerative diseases are missing. Objective: We assessed the effect of an intracerebral infection with E. coli in a mouse model of AD. Methods: 13-month-old Tg2576 +/- mice and transgene negative littermates (Tg2576 -/-) received an intracerebral injection with E. coli K1 or saline followed by treatment with ceftriaxone starting 41 h post infection (p.i.) for 5 days. For 4 weeks, mice were monitored for clinical status, weight, motor functions, and neuropsychological status using the Morris water maze. ELISAs, stainings, and immunohistochemistry in brains were performed at the end of the experiment. Results: Mortality of the infection was approximately 20%. After 4 weeks, spatial learning of infected Tg2576 +/- mice was compromised compared to non-infected Tg2576 +/- mice (p < 0.05). E. coli infection did not influence spatial learning in Tg2576 -/- mice, or spatial memory in both Tg2576 +/- and -/- mice within 4 weeks p.i.. Necrosis of hippocampal neurons was induced in infected compared to non-infected Tg2576 +/- mice 4 weeks p.i., whereas brain concentrations of Aβ1–40, Aβ1–42, and phosphoTau as well as axonal damage and microglia density were not altered. Conclusion: Here, we proved in principle that a genuine acute bacterial infection can worsen cognitive functions of AD mice. Mouse models of subacute systemic infections are needed to develop new strategies for the treatment of bacterial infections in patients with AD in order to minimize their cognitive decline.

Increased Serum Neuropeptide Galanin Level Is a Predictor of Cognitive Dysfunction in Patients with Hip Fracture. DISEASE MARKERS 2021; 2021:9141978. [PMID: 34925648 PMCID: PMC8683191 DOI: 10.1155/2021/9141978] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 11/17/2021] [Accepted: 11/23/2021] [Indexed: 11/30/2022]
Abstract
Background Hip fracture is a common occurrence in elderly populations and is frequently followed by various levels of cognitive dysfunction, leading to adverse functional outcomes. Risk stratification of hip fracture patients to identify high-risk subsets can enable improved strategies to mitigate cognitive complications. The neuropeptide galanin has multiple neurological functions, and altered levels are documented in dementia-type and depression disorders. The present study investigated the association of serum neuropeptide galanin levels in hip fracture patients with the occurrence of cognitive dysfunction during the first week of admission. Methods 276 hip fracture patients without preexisting delirium, cognitive impairment, or severe mental disorders were included in a cross-sectional study. Serum galanin levels were assessed by ELISA on the second day of admission. Routine clinical and laboratory variables were documented. MoCA was performed within 1 week, and those with a score < 26 were categorized with “cognitive decline.” Inferential statistics including multiple linear regression analysis were applied to determine the association of serum galanin level and cognitive status. Results 141 patients were categorized with “cognitive decline,” and 135 patients were categorized as “cognitively normal.” Serum galanin was highly significantly increased in the “cognitive decline” group (34.2 ± 4.8, pg/ml) compared to the “cognitively normal” group (28.9 ± 3.7, pg/ml) and showed significant negative correlation with MoCA scores (r = −0.229, p = 0.016). Regression analysis showed serum galanin as the sole significant independent predictor of lower MoCA scores (β = 0.231, p = 0.035) while age, gender, blood pressure, cholesterol, and blood glucose levels had no significant association. Conclusion Higher serum galanin predicted the development of cognitive dysfunction and worse MoCA scores in a cohort of hip fracture patients without preexisting cognitive impairment or delirium at admission, thus warranting large-scale studies investigating galanin as a candidate biomarker to identify hip fracture patients at risk of cognitive decline.

Abstract
AIM To determine associations between delirium and health outcomes using the Australia and New Zealand population-based hip fracture patient registry (ANZHFR). METHODS We performed a retrospective cohort study using data from the ANZHFR among hip-fracture surgery patients admitted to and discharged from hospital between 1 January 2017 and 31 December 2018. RESULTS Of the 4904 patients with complete data and included in the analysis, 1789 (36.5%) experienced delirium during their hospital stay. Patients with delirium also had a higher rate of in-hospital mortality (adjusted HR = 1.76; 95% CI = 1.24, 2.49; P < 0.001), a higher rate of long-term mortality (adjusted HR = 1.30; 95% CI = 1.15, 1.48; P < 0.001) and a higher odds of discharge to an aged care facility (adjusted OR = 1.24; 95% CI = 1.04, 1.48; P = 0.019). CONCLUSION A high rate of postoperative delirium exists among Australian and New Zealand hip fracture patients. Rates of hospital mortality, length of hospital stay and discharge to residential aged care are considerably worse in these patients.

Red Blood Cell Transfusion and Postoperative Delirium in Hip Fracture Surgery Patients: A Retrospective Observational Cohort Study. Anesthesiol Res Pract 2021; 2021:8593257.

Abstract
Background Patients having hip fracture surgery are at high risk for postoperative delirium. Red blood cell (RBC) transfusion may increase postoperative delirium risk by causing neuroinflammation. We hypothesized that RBC transfusion would be associated with postoperative delirium in patients having hip fracture surgery. Methods An observational cohort study was performed using the United States National Surgical Quality Improvement Program (NSQIP) participant use files for hip fracture from 2016 to 2018. Propensity score analysis and inverse probability of treatment weighting (IPTW) were used to reduce bias from confounding. An IPTW adjusted odds ratio for developing postoperative delirium was calculated for patients who received RBC transfusion during surgery or in the 72 hours after. Results There were 20,838 patients who had eligible current procedural terminology (CPT) codes for primary hip fracture surgery and complete study data. After employing strict exclusions to balance covariates and reduce bias, 3,715 patients remained in the IPTW cohort. Of these, 626 patients (16.9%) received RBC transfusion and 665 patients (17.9%) developed postoperative delirium. IPTW adjustment led to good covariate balance between patients who received RBC transfusion and those who did not. Patients who received RBC transfusion had significantly higher odds of postoperative delirium, IPTW adjusted odds ratio = 1.21, 95% CI = 1.03 to 1.43, and P = 0.02. Discharge location also differed significantly between patients who received RBC transfusion and those who did not (P < 0.001) with in-hospital mortality or referral to hospice occurring in 1.6% of patients who received RBC transfusion and 1.3% of patients who were not transfused. Conclusion RBC transfusion is associated with increased odds of postoperative delirium after hip fracture surgery and may be associated with worse clinical outcome.

Abstract
OBJECTIVES There is a lack of guidance on how to manage the multiple post-discharge issues of older people following minimal trauma hip fracture. We developed a geriatrician-staffed outpatient service for people aged ≥65 years admitted with a hip fracture who were not discharged to a nursing home. We aimed to evaluate the potential benefits of the addition of a dedicated hip fracture follow-up clinic by measuring the actions performed by such a clinic. METHODS We evaluated the potential benefit of the clinic through a retrospective review of the medical records of all those referred to the clinic over a 2-year period. RESULTS A total of 80 people were provided a clinic appointment, with 43 (54%) attending. The median age of clinic attendees was 81 years. A total of 40/43 (93%) of attendees received inpatient rehabilitation in a sub-acute facility before discharge. At the dedicated outpatient clinic, multiple issues were identified and managed including further fall reduction strategies (n = 12), commencement of anti-resorptive medications (n = 11) and medication deprescribing (n = 11). CONCLUSIONS We found that the introduction of a dedicated hip fracture outpatient clinic identified and managed a broad range of issues. It is unclear if these needs would have been met by previously existing services. Further work is required to clarify whether managing these issues translates into improved patient outcomes and whether a dedicated clinic is a cost-effective practice of achieving this.

Abstract
UNLABELLED Hip fracture patients often display an acute confusional state (delirium) which is associated with worse outcomes. In this observational study, we found that co-management of hip fracture patients by a multidisciplinary team including a geriatrician and an orthopaedic surgeon could reduce the incidence of delirium. INTRODUCTION Delirium after hip fracture is common and is associated with negative outcomes. We investigated if orthogeriatric co-management reduced the incidence of delirium in hip fracture patients. METHODS In this single-centre, prospective observational study, we compared the incidence of delirium and subsyndromal delirium (SSD) before (usual care group, n = 94) and after (orthogeriatric group, n = 103) the introduction of orthogeriatric co-management as an integrated care model. The outcome measure 'no delirium/SSD/delirium' was treated as an ordinal variable and analysed using the chi-squared test and multivariable ordinal logistic regression. RESULTS The groups had similar baseline characteristics except for a higher proportion of patients with pre-existing cognitive impairment in the usual care group (51% vs. 37%, p = 0.045). Fewer patients in the orthogeriatric group developed SSD or delirium (no delirium: 59% vs. 40%/SSD: 6% vs. 13%/delirium: 35% vs. 47%; p = 0.021). The number needed to treat (NNT) to avoid one case of SSD or delirium was 5.3 (95% CI: 3.1 to 19.7). In a multivariable analysis adjusted for age, sex, ASA class, pre-existing cognitive impairment, time to surgery, type of surgery, and medical or surgical complications, the odds ratio for the development of SSD/delirium was lower in the orthogeriatric group (OR = 0.46, 95% CI: 0.23-0.89, p = 0.023). CONCLUSION Orthogeriatric co-management as an integrated care model reduced the incidence of SSD/delirium in hip fracture patients.

Abstract
BACKGROUND Delirium is associated with an increased risk of incident dementia and accelerated progression of existing cognitive symptoms. Reciprocally, dementia increases the risk of delirium. Cerebrospinal fluid (CSF) concentration of the dendritic protein neurogranin has been shown to increase in early Alzheimer's disease (AD), likely reflecting synaptic dysfunction and/or degeneration. OBJECTIVE To elucidate the involvement of synaptic dysfunction in delirium pathophysiology, we tested the association between CSF neurogranin concentration and delirium in hip fracture patients with different AD-biomarker profiles, while comparing them to cognitively unimpaired older adults (CUA) and AD patients. METHODS The cohort included hip fracture patients with (n = 70) and without delirium (n = 58), CUA undergoing elective surgery (n = 127), and AD patients (n = 46). CSF was collected preoperatively and diagnostically in surgery and AD patients respectively. CSF neurogranin concentrations were analyzed in all samples with an in-house ELISA. Delirium was assessed pre-and postoperatively in hip fracture patients by trained investigators using the Confusion Assessment Method. Hip fracture patients were further stratified based on pre-fracture dementia status, delirium subtype, and AD fluid biomarkers. RESULTS No association was found between delirium and CSF neurogranin concentration (main analysis: delirium versus no delirium, p = 0.68). Hip fracture patients had lower CSF neurogranin concentration than AD patients (p = 0.001) and CUA (p = 0.035) in age-adjusted sensitivity analyses. CONCLUSION The findings suggest that delirium is not associated with increased CSF neurogranin concentration in hip fracture patients, possibly due to advanced neurodegenerative disease and age and/or because synaptic degeneration is not an important pathophysiological process in delirium.

Abstract
Introduction The Nottingham Hip Fracture Score (NHFS) was developed to predict 30-day mortality for patients with hip fracture. This study aimed to validate the NHFS in a cohort with sufficient statistical power. Methods Data were extracted from a prospective hip-fracture database (FAMMI). Patients were included between January 1, 2018 and January 11, 2021. All consecutively admitted patients ≥18 years of age with a hip fracture (ie, femoral neck fracture, intertrochanteric fracture, and subtrochanteric fracture) were included. Mann–Whitney’s U values were calculated to find potential miscalibration of the NHFS formula. Discrimination evaluation was performed using the concordance statistic as an equivalent to area under the receiver-operating curve. Results In total, 2,458 patients were included. Mean age was 80±12 years, and 66% were women (n=1,631). Median NHFS was 5 (4–6) and overall 30-day mortality 7.9% (n=195). Overall goodness of fit was tested with Pearson’s ?2 (11.8, df 10; P=0.297). No statistically significant signs of miscalibration were found (Mann–Whitney U, P=0.08). Discrimination was tested with area under the receiver- operating curve, which was 72.1% (95% CI 68.7%–75.4%). However, observed 30-day mortality in our population of hip-fracture patients was slightly higher than the NHFS prediction. Conclusion The NHFS seemed to predict 30-day mortality with reasonable accuracy for patients with a hip fracture in a population within the Netherlands.

Abstract
OBJECTIVES Patients with dementia follow different trajectories of progression. We aimed to investigate which factors at the time of diagnosis could predict trajectory group membership. DESIGN Longitudinal observational study. SETTING Specialized memory clinic, Oslo University Hospital in Norway. PARTICIPANTS Patients assessed at the memory clinic, between 12 January 2009 and 31 July 2016, who were registered in the Norwegian Registry of persons assessed for cognitive symptoms (NorCog) and diagnosed with dementia after the baseline examination period (n = 442). The patients were followed up to 3 years, with an average of 3.5 examinations. MEASUREMENTS Clinical Dementia Rating Scale Sum of Boxes (CDR-SB), Mini-Mental State Examination (MMSE), the Consortium to Establish a Registry of Alzheimer's disease (CERAD) 10-item word list delayed recall, the Clock Drawing Test, (CDT) Trail Making Test A (TMT-A), and Neuropsychiatric Inventory Questionnaire (NPI-Q). Based on changes in scores on the CDR-SB, we used group-based trajectory modeling (GBTM) to explore the presence of trajectory groups. Multinomial logistic regression was used to explore whether a set of baseline variables could predict trajectory group membership. RESULTS Three trajectory groups were identified, one with a slow progression rate and two with more-rapid progression. Rapid progression was associated with older age, lower cognitive function (MMSE and TMT-A), and more-pronounced neuropsychiatric symptoms (NPI-Q) at the time of diagnosis. CONCLUSIONS Our findings demonstrate the heterogeneity of dementia progression and describe risk factors for rapid progression, emphasizing the need for individual follow-up regimes. For future intervention studies, our results may guide the selection of patients.

Abstract
Importance Delirium is associated with increased hospital costs, health care complications, and increased mortality. Long-term consequences of delirium on cognition have not been synthesized and quantified via meta-analysis. Objective To determine if an episode of delirium was an independent risk factor for long-term cognitive decline, and if it was, whether it was causative or an epiphenomenon in already compromised individuals. Data Sources A systematic search in PubMed, Cochrane, and Embase was conducted from January 1, 1965, to December 31, 2018. A systematic review guided by Preferred Reporting Items for Systematic Reviews and Meta-analyses was conducted. Search terms included delirium AND postoperative cognitive dysfunction; delirium and cognitive decline; delirium AND dementia; and delirium AND memory. Study Selection Inclusion criteria for studies included contrast between groups with delirium and without delirium; an objective continuous or binary measure of cognitive outcome; a final time point of 3 or more months after the delirium episode. The electronic search was conducted according to established methodologies and was executed on October 17, 2018. Data Extraction and Synthesis Three authors extracted data on individual characteristics, study design, and outcome, followed by a second independent check on outcome measures. Effect sizes were calculated as Hedges g. If necessary, binary outcomes were also converted to g. Only a single effect size was calculated for each study. Main Outcomes and Measures The planned main outcome was magnitude of cognitive decline in Hedges g effect size in delirium groups when contrasted with groups that did not experience delirium. Results Of 1583 articles, data subjected from the 24 studies (including 3562 patients who experienced delirium and 6987 controls who did not) were included in a random-effects meta-analysis for pooled effect estimates and random-effects meta-regressions to identify sources of study variance. One study was excluded as an outlier. There was a significant association between delirium and long-term cognitive decline, as the estimated effect size (Hedges g) for 23 studies was 0.45 (95% CI, 0.34-0.57; P < .001). In all studies, the group that experienced delirium had worse cognition at the final time point. The I2 measure of between-study variability in g was 0.81. A multivariable meta-regression suggested that duration of follow-up (longer with larger gs), number of covariates controlled (greater numbers were associated with smaller gs), and baseline cognitive matching (matching was associated with larger gs) were significant sources of variance. More specialized subgroup and meta-regressions were consistent with predictions that suggested that delirium may be a causative factor in cognitive decline. Conclusions and Relevance In this meta-analysis, delirium was significantly associated with long-term cognitive decline in both surgical and nonsurgical patients.

Abstract
Background Acute medical illnesses, surgical interventions, or admissions to hospital in older individuals are frequently associated with a delirium. In this cohort study, we investigated the impact of specific cognitive domains and depression before the occurrence of delirium symptoms in an 8-year observation of older non-hospitalized individuals. Methods In total, we included 807 participants (48–83 years). Deficits in specific cognitive domains were measured using the CERAD test battery, and depressive symptoms were measured using Beck Depression Inventory and the Geriatric Depression Scale (GDS) before the onset of a delirium. Delirium symptoms were retrospectively assessed by a questionnaire based on the established Nursing Delirium Screening Scale. Results Fifty-eight of eight hundred seven participants (7.2%) reported delirium symptoms over the 8-year course of the study. Sixty-nine percent (n = 40) of reported delirium symptoms were related to surgeries. In multivariate regression analysis, impaired executive function was an independent risk factor (p = 0.034) for the occurrence of delirium symptoms. Furthermore, age (p = 0.014), comorbidities [captured by the Charlson Comorbidity Index (CCI)] (p < 0.001), and depression (p = 0.012) were significantly associated with reported delirium symptoms. Conclusion Especially prior to elective surgery or medical interventions, screening for impaired executive function and depression could be helpful to identify patients who are at risk to develop delirium symptoms.

Abstract
OBJECTIVE Senile patients often experience neurocognitive disturbance after non-cardiac surgery. Several clinical trials have investigated if the perioperative intravenous use of dexmedetomidine has a positive effect on the prevention of neurocognitive dysfunction, but the results have been inconsistent. We performed a meta-analysis to investigate the effects of dexmedetomidine on neurocognitive disturbance after elective non-cardiac surgery in senile patients. METHODS The PubMed, Cochrane Library, EMBASE and China National Knowledge Infrastructure databases were comprehensively searched for all randomized controlled trials published before 1 February 2020 that investigated the efficacy of dexmedetomidine in the prevention of postoperative delirium (POD) or postoperative cognitive dysfunction (POCD). RESULTS Sixteen studies involving 4376 patients were included in this meta-analysis. Compared with the control (i.e., saline), the perioperative intravenous use of dexmedetomidine significantly reduced the incidence of POD and POCD. However, patients in the dexmedetomidine group were more likely to develop bradycardia and hypotension during the administration of dexmedetomidine than patients in the control group. There were no differences between the two groups in the incidence of nausea and vomiting or mortality rate. CONCLUSION Dexmedetomidine has a positive effect on the prevention of neurocognitive disturbance in senile patients after elective non-cardiac surgery.

Abstract
Background Delirium is common, distressing and associated with poor outcomes. Previous studies investigating the impact of delirium on cognitive outcomes have been limited by incomplete ascertainment of baseline cognition or lack of prospective delirium assessments. This study quantified the association between delirium and cognitive function over time by prospectively ascertaining delirium in a cohort aged ≥ 65 years in whom baseline cognition had previously been established. Methods For 12 months, we assessed participants from the Cognitive Function and Ageing Study II-Newcastle for delirium daily during hospital admissions. At 1-year, we assessed cognitive decline and dementia in those with and without delirium. We evaluated the effect of delirium (including its duration and number of episodes) on cognitive function over time, independently of baseline cognition and illness severity. Results Eighty two of 205 participants recruited developed delirium in hospital (40%). One-year outcome data were available for 173 participants: 18 had a new dementia diagnosis, 38 had died. Delirium was associated with cognitive decline (−1.8 Mini-Mental State Examination points [95% CI –3.5 to –0.2]) and an increased risk of new dementia diagnosis at follow up (OR 8.8 [95% CI 1.9–41.4]). More than one episode and more days with delirium (>5 days) were associated with worse cognitive outcomes. Conclusions Delirium increases risk of future cognitive decline and dementia, independent of illness severity and baseline cognition, with more episodes associated with worse cognitive outcomes. Given that delirium has been shown to be preventable in some cases, we propose that delirium is a potentially modifiable risk factor for dementia.

Abstract
Background and purpose - Unlike hip fractures, diaphyseal and distal femoral fractures in elderly patients have not been widely studied. We investigated the demographics, comorbidities and mortality of patients with femoral fractures at any anatomical level with a focus on early mortality.Patients and methods - We analyzed 11,799 patients ≥ 65 years with a femoral fracture registered in the Swedish Fracture Register from 2011 to 2014. The cohort was matched with the National Patient Register to obtain data on comorbidities classified according to the Charlson Comorbidity Index (CCI). Generalized linear models were fitted to estimate the adjusted relative risk of mortality.Results - Mean age of the cohort was 83 years and 69% were women. Patients with distal femoral fractures had the lowest degree of comorbidity, with 9% having a CCI of ≥ 3 compared with 14% among those with proximal and 16% among those with diaphyseal fractures. Unadjusted 90-day mortalities were 13% (95% CI 9.4-16) after fractures in the distal, 13% (CI 10-16) in the diaphyseal, and 15% (CI 14-15) in the proximal segment. The adjusted relative risk for 90-day mortality was 1.1 (CI 0.86-1.4) for patients with distal and 0.97 (CI 0.76-1.2) for patients with diaphyseal femoral fractures when compared with patients with hip fractures.Interpretation - Elderly patients with femoral fractures distal to the hip may have similar adjusted early mortality risks to those with hip fractures. There is a need for larger, preferably prospective, studies investigating the effect of rapid pathways and geriatric co-management for patients with diaphyseal and distal femoral fractures.

Modified Frailty Index Independently Predicts Postoperative Delirium and Delayed Neurocognitive Recovery After Elective Total Joint Arthroplasty. J Arthroplasty 2021; 36:449-453. [PMID: 32863073 DOI: 10.1016/j.arth.2020.07.074] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 07/02/2020] [Accepted: 07/28/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Postoperative delirium (POD) and delayed neurocognitive recovery are 2 common subtypes of postoperative neurocognitive disorders that occur after total joint arthroplasty (TJA), associated with inferior surgical outcomes. The modified frailty index (mFI) reflects the status of physiologic decline and predicts adverse outcomes in various surgical patient cohorts. This study aims at examining the discriminatory value of the mFI to predict POD and delayed neurocognitive recovery after TJA. METHODS The study includes 383 participants admitted for primary elective TJA under general anesthesia combined with inhalation agents over the period from January 2018 to December 2019. POD and delayed neurocognitive recovery, based on the criteria provided by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (2013), were assessed for each enrolled patient. A multivariate logistic regression analysis was performed to screen potential risk factors for POD and delayed neurocognitive recovery. RESULTS The total incidence of POD and the delayed neurocognitive recovery of this cohort were 17.2% (66/383) and 24.8% (95/383), respectively. Our data from the multivariate logistic regression analysis indicated that a higher age (≥72 years) and a higher mFI level (≥0.18) were 2 independent risk factors for both POD and delayed neurocognitive recovery in elderly subjects after TJA. CONCLUSION The mFI may be a promising predictor for both POD and delayed neurocognitive recovery in elderly subjects following TJA. Preoperative mFI evaluation can be used for risk stratification and offers significant potential in clinical application.

Binocular Vision, Visual Function, and Pupil Dynamics in People Living With Dementia and Their Relation to the Rate of Cognitive Decline and Structural Changes Within the Brain: Protocol for an Observational Study.

Abstract
BACKGROUND Visual impairment is a common comorbidity in people living with dementia. Addressing sources of visual difficulties can have a significant impact on the quality of life for people living with dementia and their caregivers. Depth perception problems are purportedly common in dementia and also contribute to falls, visuomotor task difficulties, and poorer psychosocial well-being. However, depth perception and binocular vision are rarely assessed in dementia research. Sleep fragmentation is also common for people living with dementia, and binocular cooperation for depth perception can be affected by fatigue. Pupillary responses under cognitive load also have the potential to be a risk marker for cognitive decline in people living with dementia and can be combined with the above measures for a comprehensive evaluation of clinical visual changes in people living with dementia and their relation to changes in cognitive status, sleep quality, and cortical structure or function. OBJECTIVE This study aims to characterize the nature of clinical visual changes and altered task-evoked pupillary responses that may occur in people living with dementia and evaluate whether these responses relate to changes in cognitive status (standardized Mini Mental State Examination [MMSE] score), Pittsburgh sleep quality index, and cortical structure or function. METHODS This proposed exploratory observational study will enroll ≤210 people with recently diagnosed dementia (within the last 24 months). The following parameters will be assessed on 3 occasions, 4 months apart (plus or minus 2 weeks): visual function (visual acuity and contrast sensitivity), binocular function (motor fusion and stereopsis), task-evoked pupillary responses (minimum and maximum pupil size, time to maximum dilation, and dilation velocity), cognitive status (MMSE score), and sleep quality (Pittsburgh Sleep Quality Index). A subset of patients (n=30) with Alzheimer disease will undergo structural and functional magnetic resonance imaging at first and third visits, completing a 10-day consensus sleep diary to monitor sleep quality, verified by sleep actimetry. RESULTS This research was funded in February 2018 and received National Health Service Research Ethics Committee approval in September 2018. The data collection period was from October 1, 2018, to November 30, 2019. A total of 24 participants were recruited for the study. The data analysis is complete, with results expected to be published before the end of 2020. CONCLUSIONS Findings will demonstrate how often people with dementia experience binocular vision problems. If frequent, diagnosing and treating them could improve quality of life by reducing the risk of falls and fine visuomotor task impairment and by relieving psychosocial anxiety. This research will also demonstrate whether changes in depth perception, pupillary responses, and quality of vision relate to changes in memory or sleep quality and brain structure or function. If related, these quick and noninvasive eye tests help monitor dementia. This would help justify whether binocular vision and pupillary response testing should be included in dementia-friendly eye-testing guidelines.

Abstract
PURPOSE Cognitive impairment and dementia are common in older hip fracture patients. We describe new diagnoses of cognitive disorders (NDCDs) and associated factors in a two-year post-hip fracture follow-up including the use of the diagnostic facilities of a memory clinic. METHODS Data were collected on admission and at outpatient assessment 4-6 months post-hip fracture. Diagnoses of cognitive disorders followed the evidence-based Finnish national care guideline including internationally accepted criteria. NDCDs up to 2 years post-hip fracture were extracted manually from the patient files. Logistic regression models were computed to examine the associations between the pre-fracture factors and the domains of the outpatient geriatric assessment and NDCDs. RESULTS Of the 1165 hip fracture patients aged ≥ 65 years, 831 had no previous diagnosis of cognitive disorder. Of these, NDCD was documented in 23.3%. Alzheimer's disease (AD) with or without vascular cognitive impairment (VCI) was the most common diagnosis. Cognitive disorder was usually at a moderate stage. Age, higher ASA score and poor nutritional status on admission were associated with new cognitive disorders. At the outpatient follow-up, poorer activities of daily living and mobility disability were associated with NDCD. Patients with a NDCD were more likely to suffer greater mobility impairment, poorer nutritional status and to have more supported living arrangements at follow-up than in the pre-fracture situation. CONCLUSION NDCDs are common after hip fracture and associated with impaired rehabilitation outcomes and poor nutritional status. A post-hip fracture assessment co-organized in the form of a memory clinic seems to be feasible to detect previously undiagnosed cognitive disorders. Earlier diagnosis of cognitive disorders is warranted.

Abstract
OBJECTIVES This investigation clarified the relationship between a short physical performance battery (SPPB) that can comprehensively and safely evaluate balance function, walking ability, lower limb muscle strength, and postoperative delirium. METHODS This was a retrospective observational study performed at Kobe City Medical Center General Hospital. Patients who underwent surgery at the Kobe City Medical Center General Hospital Cardiovascular Surgery from August 1, 2016 to July 31, 2017 were included. Preoperative physical functions were obtained. Those showing positive results using the confusion assessment method for intensive care unit (ICU) during the ICU stay were considered as the delirium group, and the postoperative and non-postoperative delirium groups were compared. A multiple logistic regression analysis was performed with the presence or absence of onset of delirium as the dependent variable and the SPPB total score and age as dependent variables. RESULTS There were 193 subjects in this study (120 males and 73 females). Sixteen patients (8.4 %) had postoperative delirium. The age in the postoperative delirium group was significantly higher than in the postoperative delirium group (77.8 (7.0) years vs. 70.0 (11.1) years). BMI and SPPB total score were significantly lower in the postoperative delirium group. From the multiple logistic regression, the SPPB total score (OR: 0.754, 95 % CI: 0.643-0.883, p < 0.001) was extracted as a factor related to postoperative delirium onset. CONCLUSION It was illuminated that in patients with cardiovascular surgery, preoperative low physical function was not affected by age and became a risk factor of postoperative delirium onset.

Abstract
BACKGROUND Hip fracture represents a substantial acute inflammatory trauma, which may constitute a significant insult to the degenerating brain. Research suggests that an injury of this kind can affect memory and thinking in the future but it is unclear whether, and how, inflammatory trauma injures the brain. The impact of Acute SystematiC inflammation upon cerebRospinal fluId and blood BiomarkErs of brain inflammation and injury in Dementia: a study in acute hip fracture patients (ASCRIBED) explores this relationship, to understand the effect of inflammation on the progression of dementia. METHODS This protocol describes a multi-centre sample collection observational study. The study utilises the unique opportunity provided by hip fracture operations undertaken via spinal anaesthesia to collect cerebrospinal fluid (CSF) and blood, to investigate the impact of acute brain inflammation caused by hip fracture on the exacerbation of dementia. We will recruit 200 hip fracture patients with a diagnosis or evidence of dementia; and 200 hip fracture patients without dementia. We will also recruit 'Suitable informants', individuals in regular contact with the patient, to provide further proxy evidence of a patient's potential cognitive decline. We will compare these 400 samples with existing CSF and blood samples from a cohort of dementia patients who had not experienced a systemic inflammatory response due to injury. This will provide a comparison between patients with and without dementia who are suffering a systemic inflammatory response; with stable patients living with dementia. DISCUSSION We will test the hypothesis that hip fracture patients living with dementia show elevated markers of brain inflammation, as well as neuronal injury and Alzheimer-related plaque pathology, in comparison to (1) stable patients living with dementia and (2) hip fracture patients without dementia, as measured by biomarkers in CSF and blood. The findings will address the hypothesis that systemic inflammatory events can exacerbate underlying dementia and inform the search for new treatments targeting inflammation in dementia.

Abstract
BACKGROUND Postoperative delirium and postoperative cognitive dysfunction share risk factors and may co-occur, but their relationship is not well established. The primary goals of this study were to describe the prevalence of postoperative cognitive dysfunction and to investigate its association with in-hospital delirium. The authors hypothesized that delirium would be a significant risk factor for postoperative cognitive dysfunction during follow-up. METHODS This study used data from an observational study of cognitive outcomes after major noncardiac surgery, the Successful Aging after Elective Surgery study. Postoperative delirium was evaluated each hospital day with confusion assessment method-based interviews supplemented by chart reviews. Postoperative cognitive dysfunction was determined using methods adapted from the International Study of Postoperative Cognitive Dysfunction. Associations between delirium and postoperative cognitive dysfunction were examined at 1, 2, and 6 months. RESULTS One hundred thirty-four of 560 participants (24%) developed delirium during hospitalization. Slightly fewer than half (47%, 256 of 548) met the International Study of Postoperative Cognitive Dysfunction-defined threshold for postoperative cognitive dysfunction at 1 month, but this proportion decreased at 2 months (23%, 123 of 536) and 6 months (16%, 85 of 528). At each follow-up, the level of agreement between delirium and postoperative cognitive dysfunction was poor (kappa less than .08) and correlations were small (r less than .16). The relative risk of postoperative cognitive dysfunction was significantly elevated for patients with a history of postoperative delirium at 1 month (relative risk = 1.34; 95% CI, 1.07-1.67), but not 2 months (relative risk = 1.08; 95% CI, 0.72-1.64), or 6 months (relative risk = 1.21; 95% CI, 0.71-2.09). CONCLUSIONS Delirium significantly increased the risk of postoperative cognitive dysfunction in the first postoperative month; this relationship did not hold in longer-term follow-up. At each evaluation, postoperative cognitive dysfunction was more common among patients without delirium. Postoperative delirium and postoperative cognitive dysfunction may be distinct manifestations of perioperative neurocognitive deficits.

Abstract
BACKGROUND About one fourth of patients with hip fracture have cognitive impairment. These patients are at higher risk of surgical and medical complications and are often excluded from participating in clinical research. The aim of the present study was to investigate orthopaedic surgeons' ability to determine the cognitive status of patients with acute hip fracture and to compare the treatment given to patients with and without cognitive impairment. METHODS The cognitive function of 1474 hip fracture patients reported by the orthopaedic surgeons to the nationwide Norwegian Hip Fracture Register was compared with data registered in quality databases in two hospitals with orthogeriatric service on the same patients. Cognitive function registered in the quality databases was determined either by the short form of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) or by pre-fracture diagnosis of dementia. The information registered in the quality databases was defined as the reference standard. Cognitive function in the Norwegian Hip Fracture Register was reported as: Chronic cognitive impairment? "Yes", "Uncertain" or "No" by the orthopaedic surgeons. Sensitivity, specificity, negative and positive predictive values for chronic cognitive impairment reported to the Norwegian Hip Fracture Register by the orthopaedic surgeons was calculated. Baseline data and treatment of hip fractures in patients with and without cognitive impairment in the Norwegian Hip Fracture Register were compared. RESULTS Orthopaedic surgeons reported chronic cognitive impairment in 31% of the patients. Using documented dementia or IQCODE > 4.0 as the reference, this assessment of cognitive impairment by the orthopaedic surgeons had a sensitivity of 69%, a specificity of 90%, a positive predictive value of 78%, and a negative predictive value of 84% compared to information registered in the two hospital quality databases. There were no differences in type of hip fracture or type of surgical treatment by cognitive function. CONCLUSION The treatment of hip fractures was similar in patients with chronic cognitive impairment and cognitively well-functioning patients. The surgeons had an acceptable ability to identify and report chronic cognitive impairment in the peri-operative period, indicating that the Norwegian Hip Fracture Register is a valuable resource for future registry-based research also on hip fracture patients with chronic cognitive impairment.

Abstract
BACKGROUND Delirium is associated with new-onset dementia, suggesting that delirium pathophysiology involves neuronal injury. Neurofilament light (NFL) is a sensitive biomarker for neuroaxonal injury. METHODS NFL was measured in cerebrospinal fluid (CSF) (n = 130), preoperative serum (n = 192), and postoperative serum (n = 280) in hip fracture patients, and in CSF (n = 123) and preoperative serum (n = 134) in cognitively normal older adults undergoing elective surgery. Delirium was diagnosed with the Confusion Assessment Method. RESULTS Median serum NFL (pg/mL) was elevated in delirium in hip fracture patients (94 vs. 54 pre- and 135 vs. 92 postoperatively, both p < 0.001). Median CSF NFL tended to be higher in hip fracture patients with delirium (1,804 vs. 1,636, p = 0.074). Serum and CSF NFL were positively correlated (ρ = 0.56, p < 0.001). CONCLUSION Our findings support an association between neuroaxonal injury and delirium. The correlation between serum and CSF NFL supports the use of NFL as a blood biomarker in future delirium studies.

Abstract
OBJECTIVES To determine predictors of new activities of daily living (ADLs) disability and worsened mobility disability and secondarily increased daily care hours received, in previously independent hip fracture patients. DESIGN Retrospective cohort study. SETTING Academic hospital with ambulatory follow-up. PARTICIPANTS Community-dwelling adults 65 years or older independent in ADLs undergoing hip fracture surgery in 2015 (n = 184). MEASUREMENTS Baseline, 3- and 6-month ADLs, mobility, and daily care hours received were ascertained by telephone survey and chart review. Comorbidities, medications, and characteristics of hospitalization were extracted from patient charts. Models for each outcome used logistic regression with a backward elimination strategy, adjusting a priori for age, sex, and race. RESULTS Predictors of new ADL disability at 3 months were dementia (odds ratio [OR] = 11.81; P = .001) and in-hospital delirium (OR = 4.20; P = .002), and at 6 months were age (OR = 1.04; P = .014), dementia (OR = 9.91; P = .001), in-hospital delirium (OR = 3.00; P = .031) and preadmission opiates (OR = 7.72; P = .003). Predictors of worsened mobility at 3 months were in-hospital delirium (OR = 4.48; P = .001) and number of medications (OR = 1.13; P = .003), and at 6 months were age (OR = 1.06; P = .001), preadmission opiates (OR = 7.23; P = .005), in-hospital delirium (OR = 3.10; P = .019), and number of medications (OR = 1.13; P = .013). Predictors of increased daily care hours received at 3 and 6 months were age (3 months: OR = 1.07; P = .014; 6 months: OR = 1.06; P = .017) and number of medications (3 months: OR = 1.13; P = .004; 6 months: OR = 1.22; P = .013). The proportion of patients with ADL disability and care hours received did not change from 3 to 6 months, yet there were significant improvements in mobility. CONCLUSION Age, dementia, in-hospital delirium, number of medications, and preadmission opiate use were predictors of poor outcomes in independent older adults following hip fracture. Further investigation is needed to identify factors associated with improved mobility measures from 3 to 6 months to ultimately optimize recovery.

Abstract
Background The primary aim of the present study was to verify the potential risk factors for developing a delirium after hip fracture surgery. The secondary aim of this study was to examine the related clinical outcomes after a delirium developed post-hip fracture surgery. Patients and methods Data were extracted from a prospective hip fracture database and completed by retrospective review of the hospital records. A total of 463 patients undergoing hip fracture (hip hemiarthroplasty) surgery in a level II trauma teaching hospital between January 2011 and May 2016 were included. Delirium was measured using the Delirium Observation Screening Scale, the confusion assessment method, and an observatory judgment by geriatric medicine specialists. Results The results showed that 26% of the patients (n=121) developed a delirium during hospital stay with a median duration during admission of 5 days (IQR 3–7). The multivariable model showed that the development of delirium was significantly explained by dementia (OR 2.75, P=0.001), age (OR 1.06, P=0.005), and an infection during admission (pneumonia, deep surgical site infection, or urinary tract infection) (OR 1.23, P=0.046). After 1 year of follow-up, patients who developed delirium after hip fracture surgery were significantly more discharged to (semi-independent) nursing homes (P<0.001) and had a significantly higher mortality rate (P<0.001) compared to patients without delirium after hip fracture surgery. Conclusions The results showed that 26% of the patients undergoing hip fracture surgery developed a delirium. The risk factors including age, dementia, and infection during admission significantly predicted the development of the delirium. No association was confirmed between delirium and time of admission or time to surgery. The development of delirium after hip fracture surgery was subsequently found to be a significant predictor of admission to a nursing home and mortality after 1 year.

Abstract
Hip fracture and dementia rates increase with age, and both groups of patients suffer increased morbidity and mortality and functional impairment. The management of these patients is a challenge for the orthogeriatric and rehabilitation team process, as despite the evidence on the benefit, the results analysed are still worse than in patients without cognitive impairment. For this reason, and due to the limitation in health resources, many of them have problems in accessibility to them, or are limited to a less intense rehabilitation. There are insufficient studies on the best rehabilitation interventions in this group of patients, but it is suggested: 1) to use a multidisciplinary rehabilitation model adapted to the patient with dementia, and 2) to redefine results of the rehabilitation of these patients not only in terms of functional improvement, without highlighting other concepts, such as quality of life, decrease in complications or improved social support.

Abstract
Introduction: Perioperative delirium in elderly hip fracture patients has been correlated with significant morbidity. The purpose of this study was to determine the preoperative risk factors for and short-term sequelae of postoperative delirium in geriatric hip fracture patients. Methods: We queried the American College of Surgeons National Surgical Quality Improvement Program to identify geriatric (≥65 years) patients who sustained operative hip fractures in 2016. Cohorts of patients with and without documented postoperative delirium were identified. Primary data on patient demographics and comorbidities were collected and correlated with postoperative complications and hip fracture outcome measures. Multivariate regression was used to compute risk-adjusted odds ratios (OR) of risk factors and sequelae of delirium. Results: In total, 8,439 geriatric hip fracture patients were identified of whom 2,569 patients (30.4%) had postoperative delirium. Age (OR 1.03 [1.02-1.04, p < 0.001), white race (OR 1.54 [1.19-2.00], p = 0.001), American Society of Anesthesiologists classification (OR 1.20 [1.07-1.36], p = 0.003), baseline dementia (OR 2.46 [2.11-2.86], p < 0.001), and preoperative delirium (OR 10.06 [8.12-12.45], p < 0.001) were independent risk factors for postoperative delirium in multivariate analysis. Patients with postoperative delirium had a significantly higher risk-adjusted 30-day mortality (12.0% vs. 4.8%, OR 2.22 [1.74-2.84], p < 0.001) and morbidity profile. Postoperative delirium was also independently associated with higher rates of discharge to (OR 1.65 [1.32-2.06], p < 0.001) and prolonged stay in (OR 1.79 [1.53-2.09], p < 0.001) an inpatient facility, hospital readmission (OR 1.94 [1.58-2.38], p < 0.001) and hospital length of stay (7.6 ± 5.0 vs. 6.1 ± 4.1 days, p < 0.001), as well as lower rates of immediate postoperative weight bearing (OR 0.73 [0.63-0.86], p < 0.001). Discussion: Postoperative delirium is a common occurrence in geriatric hip fractures with multiple risk factors. Delirium portends higher mortality and worse perioperative hospital-based outcomes. Conclusions: Multidisciplinary foreknowledge and management efforts are warranted to mitigate the risk of developing delirium, which strongly predicts perioperative morbidity, mortality, and hip fracture outcomes.

Abstract
OBJECTIVES The objectives of the study are to study daily hospital practice regarding detection and management and to study hyperactive and hypoactive delirium of older patients during their hospitalization. METHODS A retrospective cohort study evaluating care as usual for older hospitalized patients with delirium at Maastricht University Medical Center+, a university hospital in the Netherlands, was performed. Inclusion criteria were older hospitalized patients (65+ years), diagnosed with delirium between 1 January and 31 December 2014. Data were retrieved from the patients' medical files. Delirium was categorized as hyperactive or hypoactive. Primary outcome measures were prevalence and management (pharmacological, reorientation, screening for delirium and delirium consultations, and physical restraints). Secondary outcomes were short-term adverse outcomes. RESULTS Prevalence of delirium was 5% (N = 401), of which 77% (n = 307) was hyperactive and 23% (n = 94) was hypoactive. Significantly, more patients with a hyperactive delirium received medication to manage the delirium than patients with a hypoactive delirium (89% vs. 77%, respectively, p = 0.004). No other significant differences between the subtypes were found. CONCLUSION There was probably a strong under-recognition of delirium. Drugs were the main intervention of choice, especially for patients with hyperactive delirium. The two subtypes did not differ on non-pharmacological management. The retrospective nature of this study sheds light on the status quo of recognition, management, and care as usual for the different delirium subtypes in daily hospital practice, which may help in forming new guidelines and protocols for the detection and treatment of delirium for older patients in hospitals.

Abstract
OBJECTIVE In recent years, there has been a blossoming of studies examining cerebrospinal fluid (CSF) as a method of studying the pathophysiology of delirium. We systematically reviewed the literature for CSF studies in delirium and provide here a summary of the implications for our understanding of delirium pathophysiology. We also summarise the methods used for CSF analysis and discuss challenges and implications for future studies. METHODS In this systematic review, we screened MEDLINE, EMBASE, PsycINFO, Web of Science, PubMed and the Cochrane Library for articles on CSF biomarkers in delirium, published on 3 September 2016. Studies were required to use Diagnostic and Statistical Manual of Mental Disorders or International Classification of Diseases criteria for delirium or a validated tool. We excluded case reports. There were no other restrictions on study type. RESULTS We identified 3280 articles from our initial search, and 22 articles were included in this review. All studies were prospective, including over 400 patients with delirium and 700 controls. More than 70 different biomarkers were studied. Studies could not be compared with each other for meta-analysis because of their heterogeneity and varied widely in their risk of bias and quality assessments. CONCLUSIONS The 22 studies identified in this review reveal a small but growing literature, in which many of the important hypotheses in delirium pathogenesis have been examined, but from which few firm conclusions can currently be drawn. Nevertheless, the overall interpretation of the literature supports the vulnerable brain concept, that is, that biomarker evidence of, for example, Alzheimer's disease pathology and/or neuroinflammation, is associated with delirium.

Abstract
PURPOSE OF REVIEW The extrinsic risk factors for postoperative cognitive disturbance have been a source of concern during the perioperative period, and these risk factors remain the subject of controversy. This review of recent studies focuses on the effect of these factors on postoperative cognitive disturbance during the perioperative period. RECENT FINDINGS Impairment of cerebral autoregulation may predispose patients to intraoperative cerebral malperfusion, which may subsequently induce postoperative cognitive disturbance. The neurotoxicity of several volatile anesthetics may contribute to cognitive functional decline, and the impact of intravenous anesthesia on cognitive function requires further exploration. Multimodal analgesia may not outperform traditional postoperative analgesia in preventing postoperative delirium. Furthermore, acute pain and chronic pain may exacerbate the cognitive functional decline of patients with preexisting cognitive impairment. The nuclear factor-kappa beta pathway is an important node in the neuroinflammatory network. SUMMARY Several intraoperative factors are associated with postoperative cognitive disturbance. However, if these factors are optimized in perioperative management, postoperative cognitive disturbance will improve.

Abstract
Background Delirium in older hospitalised patients is a common and serious disorder. Polypharmacy and certain medications are risk factors for developing delirium. A medication review could benefit older hospitalised patients with delirium. Objectives (1) Evaluate the effects of medication review on length of delirium, length of hospital stay, mortality, and discharge destination; and (2) describe and analyse the proposed changes to medication and its implementation by the treating physician. Setting The study was conducted at Maastricht University Medical Centre+. Methods We compared two cohorts of older patients with delirium: the first cohort from before introducing the medication review, and a second cohort 5 months after introduction of the medication review. Data were extracted from the patients’ digital medical records. Results A significant interaction effect of cohort and number of medications taken by the patient was found for duration of delirium: patients from the second cohort taking between zero and six medications had significantly shorter delirious episodes than patients in the first cohort. This effect bordered on significance for patients taking between seven and 11 medications, but disappeared for patients taking 12 or more medications. No other statistically significant differences were found between the cohorts. The proposed changes in medication were implemented for 71% of the patients. Conclusion A medication review seems to significantly decrease the length of an older patient’s delirious episode. Given the clinical relevance of these findings, we advise medication reviews for all older patients who are delirious or are at risk of developing delirium.

Does Dexmedetomidine Ameliorate Postoperative Cognitive Dysfunction? A Brief Review of the Recent Literature. Curr Neurol Neurosci Rep 2018; 18:64.

Abstract
PURPOSE OF REVIEW Postoperative cognitive dysfunction (POCD) occurs in 20-50% of postsurgical patients with a higher prevalence in elderly patients and patients with vascular disease and heart failure. In addition, POCD has been associated with many negative outcomes, such as increased hospital length of stay, increased rates of institutionalization, and higher patient mortality. This brief review discusses select evidence suggesting an association between neuroinflammation and POCD and whether the use of dexmedetomidine, a short-acting alpha 2 agonist, may ameliorate the incidence of POCD. We review the recent evidence for neuroinflammation in POCD, dexmedetomidine's properties in reducing inflammatory-mediated brain injury, and clinical studies of dexmedetomidine and POCD. RECENT FINDINGS There is evidence to support the anti-inflammatory and immunomodulatory effects of dexmedetomidine in animal models. Several clinical investigations have demonstrated favorable outcomes using dexmedetomidine over placebo for the reduction of postoperative delirium. Few studies have used high-quality endpoints for the assessment of POCD and no demonstrable evidence supports the use of dexmedetomidine for the prevention of POCD. While evidence exists for the neural anti-inflammatory properties of dexmedetomidine, human trials have yielded incomplete results concerning its use for the management of POCD. Dexmedetomidine may reduce acute postoperative delirium, but further studies are needed prior to recommending the use of dexmedetomidine for the direct reduction of POCD.

Abstract
INTRODUCTION Few population studies have investigated whether longitudinal decline after delirium in mid-to-late life might affect specific cognitive domains. METHODS Participants from a birth cohort completing assessments of search speed, verbal memory, and the Addenbrooke's Cognitive Examination at age 69 were asked about delirium symptoms between ages 60 and 69 years. Linear regression models estimated associations between delirium symptoms and cognitive outcomes. RESULTS Period prevalence of delirium between 60 and 69 years was 4% (95% confidence interval 3.2%-4.9%). Self-reported symptoms of delirium over the seventh decade were associated with worse scores in the Addenbrooke's Cognitive Examination (-1.7 points; 95% confidence interval -3.2, -0.1; P = .04). In association with delirium symptoms, verbal memory scores were initially lower, with subsequent decline in search speed by the age of 69 years. These effects were independent of other Alzheimer's risk factors. DISCUSSION Delirium symptoms may be common even at relatively younger ages, and their presence may herald cognitive decline, particularly in search speed, over this time period.

Abstract
OBJECTIVES It remains unclear to what extent postoperative delirium (POD) affects the incidence of dementia in hip fracture patients, and the methods used to detect delirium and dementia require validation. The aim of this study was to investigate the development of dementia within 3 years of femoral neck fracture repair surgery, with a focus on POD as a potential predictive factor. METHODS Patients were assessed for cognition, delirium, depression, psychological well-being, and nutritional status during their hospitalization as well as 4, 12, and 36 months after the operation. Logistic regression models were used to analyse factors associated with POD and factors associated with the development of dementia. RESULTS The study sample consisted of 135 patients without a history of dementia, of whom 20 (14.8%) were delirious preoperatively and 75 (55.5%) postoperatively. Three years after their operations, 43/135 patients (31.8%) were diagnosed with dementia. A greater portion of patients diagnosed with dementia (39/43, 90.6%) than patients with no dementia (36/92, 39.1%) were included among the 75 patients who had experienced POD (P < 0.001). In a logistic regression model, after adjustment for covariates (age, sex, diabetes, delirium pre-and postoperatively, hyperactive delirium, days with delirium, urinary tract infection, and Mini Nutritional Assessment score), POD emerged an independent predictor for the development of new dementia (odds ratio, 15.6; 95% confidence interval, 2.6-91.6) within 3 years after the operation. CONCLUSION Geriatric hip fracture patients who exhibit POD should be monitored closely for the development of dementia.

Abstract
Little is understood about the use of person-centered care (PCC) for individuals with delirium superimposed on dementia (DSD), especially in the acute care setting. As part of a larger clinical trial, the purpose of the current exploratory study was to describe examples and qualitatively derived themes of nurse-facilitated PCC for hospitalized older adults with dementia and delirium. A total of 750 delirium rounds were analyzed across three diverse acute care sites. Qualitative derived themes of PCC included: (a) Knowing the Patient's Baseline; (b) Knowing the Patient's Interests and Values; (c) Enhancing Sensory Abilities to Communicate; (d) Individualizing Cognitive Stimulation; and (e) Enhancing Behavioral Approaches to Comfort and Sleep. Barriers included failure to see the patient as an individual and lack of time. Principles of PCC were effectively used, demonstrating the potential for PCC to ease the burden of DSD for all members of the health care team. [Journal of Gerontological Nursing, 43(12), 21-28.].

Abstract
BACKGROUND Delirium in hip fractured patients is a frequent complication. Dementia is an important risk factor for delirium and is common in frail elderly. This study aimed to extend the previous knowledge on risk factors for delirium and the consequences. Special attention was given to patients with dementia and delirium. METHODS This is a retrospective cohort study performed in the Amphia Hospital, Breda, the Netherlands. A full electronic patient file system (Hyperspace Version IU4: Epic, Inc., Verona, WI, USA) was used to assess data between January 2014 and September 2015. All patients presented were aged ≥70 years with a hip fracture, who underwent surgery with osteosynthesis or arthroplasty. Patients were excluded in case of a pathological or a periprosthetic hip fracture, multiple traumatic injuries, and high-energy trauma. Patient and surgical characteristics were documented. Postoperative outcomes were noted. Delirium was screened using Delirium Observation Screening Scale and dementia was assessed from medical notes. RESULTS Of a total of 566 included patients, 75% were females. The median age was 84 years (interquartile range: 9). Delirium was observed in 35%. Significant risk factors for delirium were a high American Society of Anesthesiology score, delirium in medical history, functional dependency, preoperative institutionalization, low hemoglobin level, and high amount of blood transfusion. Delirium was correlated with a longer hospital stay (P=0.001), increased association with complications (P<0.001), institutionalization (P<0.001), and 6-month mortality (P<0.001). Patients with dementia (N=168) had a higher delirium rate (57.7%, P<0.001) but a shorter hospital stay (P<0.001). There was no significant difference in the 6-month mortality between delirious patients with (34.0%) and without dementia (26.3%). CONCLUSION Elderly patients with a hip fracture are vulnerable for delirium, especially when the patient has dementia. Patients who underwent an episode of delirium were at increased risk for adverse outcomes.

Abstract
BACKGROUND Post-operative delirium and post-operative cognitive dysfunction (POCD) are both common but it has not been clarified how closely they are associated. We aimed to assess the possible relationship in a secondary analysis of data from the 'Surgery Depth of anaesthesia and Cognitive outcome'- study. METHODS We included patients aged ≥ 60 years undergoing non-cardiac surgery planned for longer than 60 min. Delirium was assessed according to the Diagnostic and Statistical Manual of Mental Disorders IV criteria in the post-anaesthesia care unit (PACU) as well as within the first week after surgery. Cognitive function was assessed with a neuropsychological test battery. Multivariable analysis of POCD was performed with consideration of predisposing and precipitating factors. RESULTS Of 1277 randomized patients, 850 (66.6%) had complete data. Delirium was found in 270 patients (32.9% of 850). We detected POCD in 162 (20.9% of 776) at 1 week and in 52 (9.4% of 553) at 3 months. In multivariable analysis (n = 808), delirium had no overall effect on POCD (P = 0.30). Patients with no delirium in PACU but with postoperative delirium within 7 days had an increased risk of POCD at 3 months (OR = 2.56 (95%-confidence interval: 1.07-6.16), P = 0.035). No significant association was found for the other subgroups. CONCLUSIONS There is no clear evidence that postoperative delirium is independently associated with POCD up to 3 months.
