Perioperative Factors Associated With Postoperative Delirium in Patients Undergoing Noncardiac Surgery: An Individual Patient Data Meta-Analysis.

Importance: Postoperative delirium (POD) is a common and serious complication after surgery. Various predisposing factors are associated with POD, but their magnitude and importance using an individual patient data (IPD) meta-analysis have not been assessed. Objective: To identify perioperative factors associated with POD and assess their relative prognostic value among adults undergoing noncardiac surgery. Data Sources: MEDLINE, EMBASE, and CINAHL from inception to May 2020. Study Selection: Studies were included that (1) enrolled adult patients undergoing noncardiac surgery, (2) assessed perioperative risk factors for POD, and (3) measured the incidence of delirium (measured using a validated approach). Data were analyzed in 2020. Data Extraction and Synthesis: Individual patient data were pooled from 21 studies and 1-stage meta-analysis was performed using multilevel mixed-effects logistic regression after a multivariable imputation via chained equations model to impute missing data. Main Outcomes and Measures: The end point of interest was POD diagnosed up to 10 days after a procedure. A wide range of perioperative risk factors was considered as potentially associated with POD. Results: A total of 192 studies met the eligibility criteria, and IPD were acquired from 21 studies that enrolled 8382 patients. Almost 1 in 5 patients developed POD (18%), and an increased risk of POD was associated with American Society of Anesthesiologists (ASA) status 4 (odds ratio [OR], 2.43; 95% CI, 1.42-4.14), older age (OR for 65-85 years, 2.67; 95% CI, 2.16-3.29; OR for >85 years, 6.24; 95% CI, 4.65-8.37), low body mass index (OR for body mass index <18.5, 2.25; 95% CI, 1.64-3.09), history of delirium (OR, 3.9; 95% CI, 2.69-5.66), preoperative cognitive impairment (OR, 3.99; 95% CI, 2.94-5.43), and preoperative C-reactive protein levels (OR for 5-10 mg/dL, 2.35; 95% CI, 1.59-3.50; OR for >10 mg/dL, 3.56; 95% CI, 2.46-5.17). Completing a college degree or higher was associated with a decreased likelihood of developing POD (OR 0.45; 95% CI, 0.28-0.72). Conclusions and Relevance: In this systematic review and meta-analysis of individual patient data, several important factors associated with POD were found that may help identify patients at high risk and may have utility in clinical practice to inform patients and caregivers about the expected risk of developing delirium after surgery. Future studies should explore strategies to reduce delirium after surgery.

Barriers and facilitators for physical activity on acute geriatric and rehabilitation wards: a survey study.

OBJECTIVES: During hospitalisation, physical inactivity is common among older patients and is associated with adverse outcomes, e.g. functional decline. This study identified barriers and facilitators of physical activity with geriatric patients during hospital admission. METHODS: This is a cross-sectional descriptive study, on two acute geriatric units and one rehabilitation unit, using a researcher-administered survey methodology in patients 70 years or older. A new questionnaire was developed based on a literature review, and was administered bedside and face-to-face with the older patients. RESULTS: 72 patients, mean age 83.6 years, completed the questionnaire. 88.9% of the participants found physical activity important during hospitalisation. The main patient-related determinants were fear of falling and symptoms of current illness (e.g. pain). The main environmental-related determinants were the presence of medical devices, and the availability of walking aids. Half of the patients felt motivated by the hospital staff, and one out of six participants felt discouraged. Receiving more assistance for walking and having access to other types of physical activity was expected to increase physical activity. Additionally, motivation from family would be a facilitator for 44.4% of the participants. CONCLUSION: Promoting physical activity on acute geriatric units will require interventions at different levels. Most importantly, focusing on interpersonal motivators and positive reinforcement by hospital staff could be beneficial strategies to increase the physical activity of older hospitalised patients.

Prognostic factors and prediction model for 1-year mortality after proximal humeral fracture.

The goal was to investigate if patient characteristics can be used to predict 1-year post-fracture mortality after proximal humeral fracture (PHF). A clinical prediction model showed that the combination of 6 pre-fracture characteristics demonstrated good predictive properties for mortality within 1 year of PHF. INTRODUCTION: Proximal humeral fractures (PFH) are the third most common major non-vertebral osteoporotic fractures in older persons and result in an increased mortality risk. The aim of this study was to investigate if patient characteristics can be used to predict 1-year post-fracture mortality. METHODS: Retrospective study with 261 patients aged 65 and older who were treated for a PHF in University Hospitals Leuven between 2016 and 2018. Baseline variables including demographics, residential status, and comorbidities were collected. The primary outcome was 1-year mortality. A clinical prediction model was developed using LASSO regression and validated using split sample and bootstrapping methods. The discrimination and calibration were evaluated. RESULTS: Twenty-seven (10.3%) participants died within 1-year post-PHF. Pre-fracture independent ambulation (p < 0.001), living at home at time of fracture (p < 0.001), younger age (p = 0.006), higher BMI (p = 0.012), female gender (p = 0.014), and low number of comorbidities (p < 0.001) were predictors for 1-year survival. LASSO regression identified 6 stable predictors for a prediction model: age, gender, Charlson comorbidity score, BMI, cognitive impairment, and pre-fracture nursing home residency. The discrimination was 0.891 (95% CI, 0.833 to 0.949) in the training sample, 0.878 (0.792 to 0.963) in the validation sample and 0.756 (0.636 to 0.876) in the bootstrapping samples. A similar performance was observed for patients with and without surgery. The developed model demonstrated good calibration. CONCLUSIONS: The combination of 6 pre-fracture characteristics demonstrated good predictive properties for mortality within 1 year of PHF. These findings can guide PHF treatment decisions.

Association between preoperative anxiety and postoperative delirium in older patients: a systematic review and meta-analysis.

BACKGROUND: Postoperative delirium (POD) is a common postoperative complication associated with multiple adverse consequences on patient outcomes and higher medical expenses. Preoperative anxiety has been suggested as a possible precipitating factor for the development of POD. As such, we aimed to explore the association between preoperative anxiety and POD in older surgical patients. METHODS: Electronic databases including MEDLINE (via PubMed), EMBASE (via Embase.com), Web of Science Core Collection, Cumulative Index to Nursing and Allied Health Literature (CINAHL Complete; via EBSCOhost) and clinical trial registries were systematically searched to identify prospective studies examining preoperative anxiety as a risk factor for POD in older surgical patients. We used Joanna Briggs Institute Critical Appraisal Checklist for Cohort Studies to assess the quality of included studies. The association between preoperative anxiety and POD was summarized with odds ratios (ORs) and 95% confidence intervals (CIs) using DerSimonian-Laird random-effects meta-analysis. RESULTS: Eleven studies were included (1691 participants; mean age ranging between 63.1-82.3 years). Five studies used a theoretical definition for preoperative anxiety, with the Anxiety subscale of Hospital Anxiety and Depression Scale (HADS-A) as the instrument being most often used. When using dichotomized measures and within the HADS-A subgroup analysis, preoperative anxiety was significantly associated with POD (OR = 2.17, 95%CI: 1.01-4.68, I2 = 54%, Tau2 = 0.4, n = 5; OR = 3.23, 95%CI: 1.70-6.13, I2 = 0, Tau2 = 0, n = 4; respectively). No association was observed when using continuous measurements (OR = 0.99, 95%CI: 0.93-1.05, I2 = 0, Tau2 = 0, n = 4), nor in the subgroup analysis of STAI-6 (six-item version of state scale of Spielberger State-Trait Anxiety Inventory, OR = 1.07, 95%CI: 0.93-1.24, I2 = 0, Tau2 = 0, n = 2). We found the overall quality of included studies to be moderate to good. CONCLUSIONS: An unclear association between preoperative anxiety and POD in older surgical patients was found in our study. Given the ambiguity in conceptualization and measurement instruments used for preoperative anxiety, more research is warranted in which a greater emphasis should be placed on how preoperative anxiety is operationalized and measured.

Effectiveness of transmural team-based palliative care in prevention of hospitalizations in patients at the end of life: A systematic review and meta-analysis.

BACKGROUND: Team-based palliative care interventions have shown positive results for patients at the end of life in both hospital and community settings. However, evidence on the effectiveness of transmural, that is, spanning hospital and home, team-based palliative care collaborations is limited. AIM: To systematically review whether transmural team-based palliative care interventions can prevent hospital admissions and increase death at home. DESIGN: Systematic review and meta-analysis. DATA SOURCES: MEDLINE (Ovid), Embase (Ovid), CINAHL (Ebsco), PsychINFO (Ovid), and Cochrane Library (Wiley) were systematically searched until January 2021. Studies incorporating teams in which hospital and community professionals co-managed patients, hospital-based teams with community follow-up, and case-management interventions led by palliative care teams were included. Data was extracted by two researchers independently. RESULTS: About 19 studies were included involving 6614 patients, of whom 2202 received an intervention. The overall pooled odds ratio of at least one hospital (re)admissions was 0.46 (95% confidence interval (CI) 0.34-0.68) in favor of the intervention group. The highest reduction in admission was in the hospital-based teams with community follow-up: OR 0.21 (95% CI 0.07-0.66). The pooled effect on home deaths was 2.19 (95% CI 1.26-3.79), favoring the intervention, with also the highest in the hospital-based teams: OR 4.77 (95% CI 1.23-18.47). However, studies had high heterogeneity regarding intervention, study population, and follow-up time. CONCLUSION: Transmural team-based palliative care interventions, especially hospital-based teams that follow-up patients at home, show an overall effect on lowering hospital admissions and increasing the number of patients dying at home. However, broad clinical and statistical heterogeneity of included studies results in uncertainty about the effect size.

Identifying vulnerable older adults at risk for functional decline in cardiac care wards: time to shift the paradigm.

OBJECTIVE: To determine whether routine screening with the Flemish version of the Triage Risk Screening Tool (fTRST) is a valid approach to determine which patients on cardiac care wards are at risk for inhospital functional decline and would benefit from geriatric expertise consultation. METHODS: A secondary data-analysis of the G-COACH before-cohort, describing patient profiles and routine care processes, in 189 older adults on two cardiac care wards in the University Hospitals Leuven between September 2016 and June 2017. Inhospital functional decline was defined as an increase of at least one point on the Katz Index of Activities of Daily Living or death between hospital admission and discharge. RESULTS: Nine in 10 patients had at least one geriatric syndrome and one-third developed functional decline. Based on the fTRST proposed cut-off of ≥2, 156 (82.5%) patients were at risk for functional decline (sensitivity of 95.2%, specificity of 23.8%, negative predictive value of 90.9% and Area Under the Curve of 0.60). Of the 156 'at risk' patients, 43 (27.6%) received a consultation by the geriatric consultation team after a median of four hospitalization days. A positive fTRST was not significantly related to geriatric consultations (x2 = 0.57; p = 0.45). CONCLUSION: The fTRST has a low discriminative value in identifying older cardiology patients at risk for functional decline. Given the high prevalence of geriatric syndromes, we propose a new paradigm were all older adults on cardiac care wards undergo a needs assessment upon hospital admission.

Experiences with the implementation of remote monitoring in patients with COVID-19: A qualitative study with patients and healthcare professionals.

INTRODUCTION: This study investigated how patients with COVID-19, telemonitoring (TM) teams, general practitioners (GPs) and primary care nurses in Belgium experienced remote patient monitoring (RPM) in 12 healthcare organizations, in relation to the patients' illness, health, and care needs, perceived quality of care, patient and health system outcomes, and implementation challenges. DESIGN: A qualitative research approach was adopted, including focus group discussions and semi-structured interviews. METHODS: Four different groups of participants were interviewed, that is, patients (n = 17), TM teams (n = 27), GPs (n = 16), and primary care nurses (n = 12). An interview guide was drafted based on a literature review. Interviews were transcribed verbatim, and NVivo was used for managing and analyzing the data. The QUAGOL method was used to guide the data analysis process and was adapted for the purpose of a thematic content analysis. RESULTS: All participants agreed that RPM-reassured patients. The overall perceived value of RPM for individual patients depended on how well the intervention matched with their needs. Patients who did not have the necessary language (Dutch/French speaking) and digital skills, who did not have the right equipment (smartphone or tablet), or who missed the necessary infrastructure (no internet coverage in their region) were often excluded. Remote patient monitoring also reassured healthcare professionals as it gave them information on a disease they had little knowledge about. Professionals involved in RPM experienced a high workload. All TM teams agreed that quality of data was a key factor to ensure an adequate follow-up, but they differed in what they found important. The logistic management of RPM was a challenge because of the contagious character of COVID-19, and the need for an effective information flow between the hospital team and primary care providers. Participants missed clarification about who was accountable for the care for patients in the projects. Primary care nurses and GPs missed access to RPM data. All agreed that the funding they received was not sufficient to cover all the costs associated with RPM. CONCLUSION: Healthcare professionals and patients perceive RPM as valuable and believe that the concept will have its place in the Belgium health system. However, current RPM practice is challenged by many barriers, and the sustainability of RPM implementation is low. CLINICAL RELEVANCE: Remote patient monitoring (RPM) was perceived as a valuable intervention for patients with COVID-19, but there were important concerns about unequal access to care. While the technology for RPM is available, the sustainability of implementation is low because of concerns with data quality, challenging logistics within projects, lack of data integration and communication, and a lack of an overarching guiding framework.

Prediction models for functional status in community dwelling older adults: a systematic review.

BACKGROUND: Disability poses a burden for older persons, and is associated with poor outcomes and high societal costs. Prediction models could potentially identify persons who are at risk for disability. An up to date review of such models is missing. OBJECTIVE: To identify models developed for the prediction of functional status in community dwelling older persons. METHODS: A systematic review was performed including studies of older persons that developed and/or validated prediction models for the outcome functional status. Medline and EMBASE were searched, and reference lists and prospective citations were screened for additional references. Risk of bias was assessed using the PROBAST-tool. The performance of models was described and summarized, and the use of predictors was collated using the bag-of-words text mining procedure. RESULTS: Forty-three studies were included and reported 167 evaluations of prediction models. The median c-statistic values for the multivariable development models ranged between 0.65 and 0.76 (minimum = 0.58, maximum = 0.90), and were consistently higher than the values of the validation models for which median c-statistic values ranged between 0.6 and 0.68 (minimum = 0.50, maximum = 0.81). A total of 559 predictors were used in the models. The five predictors most frequently used were gait speed (n = 47), age (n = 38), cognition (n = 27), frailty (n = 24), and gender (n = 22). CONCLUSIONS: No model can be recommended for implementation in practice. However, frailty models appear to be the most promising, because frailty components (e.g. gait speed) and frailty indexes demonstrated good to excellent predictive performance. However, the risk of study bias was high. Substantial improvements can be made in the methodology.

How to implement geriatric co-management in your hospital? Insights from the G-COACH feasibility study.

BACKGROUND: Geriatric co-management is advocated to manage frail patients in the hospital, but there is no guidance on how to implement such programmes in practice. This paper reports our experiences with implementing the 'Geriatric CO-mAnagement for Cardiology patients in the Hospital' (G-COACH) programme. We investigated if G-COACH was feasible to perform after the initial adoption, investigated how well the implementation strategy was able to achieve the implementation targets, determined how patients experienced receiving G-COACH, and determined how healthcare professionals experienced the implementation of G-COACH. METHODS: A feasibility study of the G-COACH programme was performed using a one-group experimental study design. G-COACH was previously implemented on two cardiac care units. Patients and healthcare professionals participating in the G-COACH programme were recruited for this evaluation. The feasibility of the programme was investigated by observing the reach, fidelity and dose using registrations in the electronic patient record and by interviewing patients. The success of the implementation reaching its targets was evaluated using a survey that was completed by 48 healthcare professionals. The experiences of 111 patients were recorded during structured survey interviews. The experiences of healthcare professionals with the implementation process was recorded during 6 semi-structured interviews and 4 focus groups discussions (n = 27). RESULTS: The programme reached 91% in a sample of 151 patients with a mean age of 84 years. There was a high fidelity for the major components of the programme: documentation of geriatric risks (98%), co-management by specialist geriatrics nurse (95%), early rehabilitation (80%), and early discharge planning (74%), except for co-management by the geriatrician (32%). Both patients and healthcare professionals rated G-COACH as acceptable (95 and 94%) and feasible (96 and 74%). The healthcare professionals experienced staffing, competing roles and tasks of the geriatrics nurse and leadership support as important determinants for implementation. CONCLUSIONS: The implementation strategy resulted in the successful initiation of the G-COACH programme. G-COACH was perceived as acceptable and feasible. Fidelity was influenced by context factors. Further investigation of the sustainability of the programme is needed. TRIAL REGISTRATION: ISRCTN22096382 (21/05/2020).

Patient-related risk factors for in-hospital functional decline in older adults: A systematic review and meta-analysis.

BACKGROUND: Functional decline (FD) is a common and serious problem among hospitalised older adults. OBJECTIVE: This systematic review and meta-analysis aims to identify patient-related risk factors for in-hospital FD in older adults. METHODS: Previous reviews on this topic (1970-2007) and the databases PubMed, Embase, and CINAHL (January 2007-December 2020) were searched. Reference lists of included articles were screened. Studies investigating patient-related risk factors for FD from (pre)admission to discharge in older adults admitted to an acute geriatric or internal medical unit were included. Study quality was assessed using the modified Newcastle-Ottawa Scale. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were estimated using random-effects models. The quality of evidence was assessed using GRADE. RESULTS: Twenty-nine studies met the inclusion criteria. Statistically significant risk factors were living in a nursing home (OR, 2.42; 95% CI, 1.29-4.52), impairment in instrumental activities of daily living (OR, 2.08; 95% CI, 1.51-2.86), history of falls (OR, 1.71; 95% CI, 1.00-2.92), cognitive impairment (OR, 1.83; 95% CI, 1.56-2.14), dementia (OR, 1.71; 95% CI, 1.23-2.38), delirium (OR, 2.34; 95% CI, 1.88-2.93), (risk of) malnutrition (OR, 1.76; 95% CI, 1.03-3.03), hypoalbuminemia (OR, 1.79; 95% CI, 1.36-2.36), comorbidity (OR, 1.09; 95% CI, 1.03-1.16), and the presence of pressure ulcers (OR, 3.33; 95% CI, 1.82-6.09). The narrative synthesis suggested prehospital FD, needing assistance with walking, and low body mass index as additional risk factors. CONCLUSIONS: Several patient-related risk factors for in-hospital FD were identified that can be used at hospital admission to identify older patients at risk of FD.

Care programs and their components for patients with idiopathic pulmonary fibrosis: a systematic review.

BACKGROUND: The multidimensional and complex care needs of patients with idiopathic pulmonary fibrosis (IPF) call for appropriate care models. This systematic review aimed to identify care models or components thereof that have been developed for patients with IPF in the outpatient clinical care, to describe their characteristics from the perspective of chronic integrated care and to describe their outcomes. METHODS: A systematic review was conducted using state-of-the-art methodology with searches in PubMed/Medline, Embase, CINAHL and Web Of Science. Researchers independently selected studies and collected data, which were described according to the Chronic Care Model (CCM). RESULTS: Eighteen articles were included describing 13 new care models or components. The most commonly described CCM elements were 'delivery system design' (77%) and 'self-management support' (69%), with emphasis on team-based and multidisciplinary care provision and education. The most frequently described outcome was health-related quality of life. CONCLUSIONS: Given the high need for integrated care and the scarcity and heterogeneity of data, developing, evaluating and implementing new models of care for patients with IPF and the comprehensive reporting of these endeavours should be a priority for research and clinical care.

Prediction models for hospital readmissions in patients with heart disease: a systematic review and meta-analysis.

OBJECTIVE: To describe the discrimination and calibration of clinical prediction models, identify characteristics that contribute to better predictions and investigate predictors that are associated with unplanned hospital readmissions. DESIGN: Systematic review and meta-analysis. DATA SOURCE: Medline, EMBASE, ICTPR (for study protocols) and Web of Science (for conference proceedings) were searched up to 25 August 2020. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies were eligible if they reported on (1) hospitalised adult patients with acute heart disease; (2) a clinical presentation of prediction models with c-statistic; (3) unplanned hospital readmission within 6 months. PRIMARY AND SECONDARY OUTCOME MEASURES: Model discrimination for unplanned hospital readmission within 6 months measured using concordance (c) statistics and model calibration. Meta-regression and subgroup analyses were performed to investigate predefined sources of heterogeneity. Outcome measures from models reported in multiple independent cohorts and similarly defined risk predictors were pooled. RESULTS: Sixty studies describing 81 models were included: 43 models were newly developed, and 38 were externally validated. Included populations were mainly patients with heart failure (HF) (n=29). The average age ranged between 56.5 and 84 years. The incidence of readmission ranged from 3% to 43%. Risk of bias (RoB) was high in almost all studies. The c-statistic was <0.7 in 72 models, between 0.7 and 0.8 in 16 models and >0.8 in 5 models. The study population, data source and number of predictors were significant moderators for the discrimination. Calibration was reported for 27 models. Only the GRACE (Global Registration of Acute Coronary Events) score had adequate discrimination in independent cohorts (0.78, 95% CI 0.63 to 0.86). Eighteen predictors were pooled. CONCLUSION: Some promising models require updating and validation before use in clinical practice. The lack of independent validation studies, high RoB and low consistency in measured predictors limit their applicability. PROSPERO REGISTRATION NUMBER: CRD42020159839.

Geriatric co-management for cardiology patients in the hospital: A quasi-experimental study.

BACKGROUND/OBJECTIVES: Older patients admitted to cardiac care units often suffer functional decline. We evaluated whether a nurse-led geriatric co-management program leads to better functional status at hospital discharge. DESIGN: A quasi-experimental before-and-after study was performed between September 2016 and December 2018, with the main endpoint at hospital discharge and follow-up at 6 months. SETTING: Two cardiac care units of the University Hospitals Leuven. PARTICIPANTS: One hundred and fifty-one intervention and 158 control patients aged 75 years or older admitted for acute cardiovascular disease or transcatheter aortic valve implantation. INTERVENTION: A nurse from the geriatrics department performed a comprehensive geriatric assessment within 24 h of admission. The cardiac care team and geriatrics nurse drafted an interdisciplinary care plan, focusing on early rehabilitation, discharge planning, promoting physical activity, and preventing geriatric syndromes. The geriatrics nurse provided daily follow-up and coached the cardiac team. A geriatrician co-managed patients with complications. MEASUREMENTS: The primary outcome was functional status measured using the Katz Index for independence in activities of daily living (ADL; one-point difference was considered clinically relevant). Secondary outcomes included the incidence of ADL decline and complications, length of stay, unplanned readmissions, survival, and quality of life. RESULTS: The mean age of patients was 85 years. Intervention patients had better functional status at hospital discharge (8.9, 95% CI = 8.7-9.3 versus 9.5, 95% CI = 9.2-9.9; p = 0.019) and experienced 18% less functional decline during hospitalization (25% vs. 43%, p = 0.006). The intervention group experienced significantly fewer cases of delirium and obstipation during hospitalization, and significantly fewer nosocomial infections. At 6-month follow-up, patients had significantly better functional status and quality of life. There were no differences regarding length of stay, readmissions, or survival. CONCLUSION: This first nurse-led geriatric co-management program for frail patients on cardiac care units was not effective in improving functional status, but significantly improved secondary outcomes.

Adherence to recommendations of inpatient geriatric consultation teams: a multicenter observational study.

PURPOSE: Inpatient geriatric consultation teams (IGCTs) provide recommendations for the care of older patients hospitalized on non-geriatric wards based on comprehensive geriatric assessment. The lack of adherence to their recommendations hinders the potential impact of IGCTs. We evaluated the adherence to IGCT recommendations and determined which team and recommendation characteristics are related to higher adherence rates. METHODS: Multicenter observational study in older adults aged ≥ 75 years admitted to an acute non-geriatric ward. Demographic and adherence data were collected for 30 consecutive patients. A cross-sectional survey mapped team and organizational characteristics of the participating IGCTs. RESULTS: Analyses were conducted in 278 patients (51.4% male, mean age 82.5 years, and median length of stay 10 days). There was a median number of 3 recommendations (range 1-13) per patient. The overall adherence rate was 69.7%. Recommendations related to 'social status' (82.4%) and 'functional status/mobility' (73.3%) were best adhered to. Recommendations related to 'medication' (53.2%) and 'nutritional status' (59.1%) were least adhered to. Adherence rates increased if recommendations were given to allied health professionals (OR = 6.37, 95% CI = 1.15-35.35) or by more experienced IGCTs (OR = 1.34, 95% CI = 1.04-1.72) and decreased when more recommendations were given (OR = 0.51, 95% CI = 0.33-0.80). CONCLUSION: Adherence rate to IGCT recommendations increased if given to allied health professionals or by more experienced IGCTs and when fewer recommendations were given. Study replication in an international multicenter study with a larger number of centers and evaluating the quality of the recommendations is suggested.

Is preoperative anxiety associated with postoperative delirium in older persons undergoing cardiac surgery? Secondary data analysis of a randomized controlled trial.

BACKGROUND: Although many studies have reported numerous risk factors for postoperative delirium, data are scarce about preoperative anxiety as a risk factor. The study aimed to investigate the association between preoperative anxiety and postoperative delirium in older patients undergoing cardiac surgery. METHODS: Secondary data analysis of a randomized, observer-blind, controlled trial. A total of 190 patients 65 years or older and admitted to the intensive care unit and cardiac surgery unit of a university hospital scheduled for elective on-pump cardiac surgery were included. State anxiety was measured preoperatively using the Amsterdam Preoperative Anxiety and Information Scale and the Visual Analogue Scale for anxiety. Incidence of delirium was measured during the first 5 postoperative days using the Confusion Assessment Method for Intensive Care Unit (when ventilated), or the 3 Minute Diagnostic Interview for Confusion Assessment Method (when extubated) and by daily chart review. RESULTS: Preoperative state anxiety was reported by 31% of the patients and 41% had postoperative delirium. A multiple step logistic regression analyses revealed no association between preoperative anxiety and postoperative delirium. Significant risk factors for postoperative delirium were age (OR = 1.10, 95% CI (1.03-1.18)), activities of daily living (0.69, 95% CI (0.50-0.96)), diabetes mellitus (OR = 3.15, 95% CI (1.42-7.00)) and time on cardiopulmonary bypass (OR = 1.01, 95% CI (1.00 to 1.02)). CONCLUSIONS: No relationship could be found between preoperative anxiety and postoperative delirium.

Predicting hospitalisation-associated functional decline in older patients admitted to a cardiac care unit with cardiovascular disease: a prospective cohort study.

BACKGROUND: Up to one in three of older patients who are hospitalised develop functional decline, which is associated with sustained disability, institutionalisation and death. This study developed and validated a clinical prediction model that identifies patients who are at risk for functional decline during hospitalisation. The predictive value of the model was compared against three models that were developed for patients admitted to a general medical ward. METHODS: A prospective cohort study was performed on two cardiac care units between September 2016 and June 2017. Patients aged 75 years or older were recruited on admission if they were admitted for non-surgical treatment of an acute cardiovascular disease. Hospitalisation-associated functional decline was defined as any decrease on the Katz Index of Activities of Daily Living between hospital admission and discharge. Predictors were selected based on a review of the literature and a prediction score chart was developed based on a multivariate logistic regression model. RESULTS: A total of 189 patients were recruited and 33% developed functional decline during hospitalisation. A score chart was developed with five predictors that were measured on hospital admission: mobility impairment = 9 points, cognitive impairment = 7 points, loss of appetite = 6 points, depressive symptoms = 5 points, use of physical restraints or having an indwelling urinary catheter = 5 points. The score chart of the developed model demonstrated good calibration and discriminated adequately (C-index = 0.75, 95% CI (0.68-0.83) and better between patients with and without functional decline (chi2 = 12.8, p = 0.005) than the three previously developed models (range of C-index = 0.65-0.68). CONCLUSION: Functional decline is a prevalent complication and can be adequately predicted on hospital admission. A score chart can be used in clinical practice to identify patients who could benefit from preventive interventions. Independent external validation is needed.

Clinical Outcomes of Rate vs Rhythm Control for Atrial Fibrillation in Older People: A Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Atrial fibrillation (AF) is highly prevalent in older adults and has been associated with increased morbidity and mortality. To reduce this AF-related morbidity in older adults, antiarrhythmic drugs (AADs) are regularly used for rhythm control, assuming that increasing time in sinus rhythm reduces AF-related morbidity. However, whether AADs can improve clinical outcomes in older adults remains unclear because of the increased risk for adverse drug events compared with rate control. The aim of this study was to determine the impact of rhythm control versus rate control on clinical outcomes in older adults with AF. DESIGN AND METHODS: We conducted a systematic review and meta-analysis targeting patients aged ≥65 years with AF and using drugs to control rate or rhythm. Articles that met the following criteria were included: enrolled older patients (sample mean ≥75 years) with AF, compared pharmacological rate versus rhythm control, and reported all-cause mortality, cardiovascular mortality, or ischemic stroke. RESULTS: Five observational studies were included. In total, 86,926 patients with AF with a mean age ranging from 75 to 92 years were studied. No differences were found between rhythm and rate control for all-cause mortality (odds ratio [OR] 1.11; 95% confidence interval [CI] 0.78-1.59; I2 = 79.6%; n = 28,526; four studies) and cardiovascular mortality (OR 1.09; 95% CI 0.81-1.47; I2 = 0%; n = 2292; two studies). Rhythm control resulted in fewer strokes (OR 0.86; 95% CI 0.80-0.93; I2 = 0%; n = 59,496), although this was mainly determined by one study. CONCLUSION: All collected data were observational, which precluded making strong recommendations. Furthermore, all CIs were wide, increasing the uncertainty of the observed effects. As such, evidence was insufficient to recommend rhythm or rate control as the first-line therapy for AF in older adults. As AF is particularly prevalent in older people, more randomized controlled trials are needed in this population.

Impact of geriatric co-management programmes on outcomes in older surgical patients: update of recent evidence.

PURPOSE OF REVIEW: To determine the impact of geriatric co-management programmes on outcomes in older patients undergoing a surgical procedure. RECENT FINDINGS: Twelve programmes were identified. Time to surgery was decreased in two of four studies [pooled mean difference = -0.7 h (95% CI, -3.1 to 4.4)]. The incidence of complications was reduced in two of seven studies (pooled absolute risk reduction = -4% (95% CI -10 to 2%)). Length of stay was reduced in four of eight studies [pooled mean difference = -1.4 days (95% CI -2.7 to -0.1)]. In-hospital mortality was reduced in one of six studies [pooled absolute risk reduction = -2% (95% CI -4 to -0%)]. Unplanned hospital readmissions at 30 days follow-up was reduced in two of three studies [pooled absolute risk reduction = -3% (95% CI -5 to -0%)]. SUMMARY: There was a shorter length of stay, less mortality and a lower readmission rate. However, there was uncertainty whether the results are clinically relevant and the GRADE of evidence was low. It was uncertain whether the outcomes time to surgery and complications were improved. The evidence is limited to hip fracture patients.

The European Union's Ambient and Assisted Living Joint Programme: An evaluation of its impact on population health and well-being.

The Ambient Assisted Living Joint Programme, instituted in 2008 by the European Union, aimed to create better living conditions for older adults through the funding of information and communications technology projects. This review aimed to uncover what can be learned from the Ambient Assisted Living Joint Programme by determining (1) the target populations served, (2) technology-based interventions used and (3) effects on health and well-being outcomes. Information from the Ambient Assisted Living catalogue, project websites and deliverables and from papers in PubMed and EMBASE was reviewed. Overall, 152 projects from the first six rounds of funding were identified. Sensors, computers, phones, tablets and televisions were used for various purposes, that is, monitoring, feedback, coaching, reminders and communication. In total, 12 projects reported evaluating health and well-being outcomes; however, these evaluations demonstrated poor methodological quality. Only three projects reported exact values. For all other projects, published evidence on the effect of these projects on health and well-being outcomes was not available.
