Contextual determinants influencing the implementation of fall prevention in the community: a scoping review

BACKGROUND: Successful implementation of multifactorial fall prevention interventions (FPIs) is essential to reduce increasing fall rates in community-dwelling older adults. However, implementation often fails due to the complex context of the community involving multiple stakeholders within and across settings, sectors, and organizations. As there is a need for a better understanding of the occurring context-related challenges, the current scoping review purposes to identify what contextual determinants (i.e., barriers and facilitators) influence the implementation of FPIs in the community. METHODS: A scoping review was performed using the Arksey and O'Malley framework. First, electronic databases (Pubmed, CINAHL, SPORTDiscus, PsycINFO) were searched. Studies that identified contextual determinants that influence the implementation of FPIs in the community were included. Second, to both validate the findings from the literature and identify complementary determinants, health and social care professionals were consulted during consensus meetings (CMs) in four districts in the region of Utrecht, the Netherlands. Data were analyzed following a directed qualitative content analysis approach, according to the 39 constructs of the Consolidated Framework for Implementation Research. RESULTS: Fourteen relevant studies were included and 35 health and social care professionals (such as general practitioners, practice nurses, and physical therapists) were consulted during four CMs. Directed qualitative content analysis of the included studies yielded determinants within 35 unique constructs operating as barriers and/or facilitators. The majority of the constructs ( n  = 21) were identified in both the studies and CMs, such as "networks and communications", "formally appointed internal implementation leaders", "available resources" and "patient needs and resources". The other constructs ( n  = 14) were identified only in the . DISCUSSION: Findings in this review show that a wide array of contextual determinants are essential in achieving successful implementation of FPIs in the community. However, some determinants are considered important to address, regardless of the context where the implementation occurs. Such as accounting for time constraints and financial limitations, and considering the needs of older adults. Also, broad cross-sector collaboration and coordination are required in multifactorial FPIs. Additional context analysis is always an essential part of implementation efforts, as contexts may differ greatly, requiring a locally tailored approach

Prognostic value of screening instrument based on the Dutch national VMS guidelines for older patients in the emergency department

PURPOSE: It is important to identify which older patients attending the emergency department are at risk of adverse outcomes to introduce preventive interventions. This study aimed to assess the prognostic value of a shortened screening instrument based on the Dutch national Safety Management System [Veiligheidsmanagementsysteem (VMS)] guidelines for adverse outcomes in older emergency department patients. METHODS: A cohort study was performed including patients aged 70 years or older who visited the emergency department. Adverse outcomes included hospital admission, return emergency department visits within 30 days, and 90-day mortality. The prognostic value of the VMS-score was assessed for these adverse events and, in addition, a prediction model was developed for 90-day mortality. RESULTS: A high VMS-score was independently associated with an increased risk of hospital admission [OR 2.26 (95% CI 1.32-3.86)] and 90-day mortality [HR 2.48 (95% CI 1.31-4.71)]. The individual VMS-questions regarding history of delirium and help in activities of daily living were associated with these outcomes as well. A prediction model for 90-day mortality was developed and showed satisfactory calibration and good discrimination [AUC 0.80 (95% CI 0.72-0.87)]. A cut-off point that selected 30% of patients at the highest risk yielded a sensitivity of 67.4%, a specificity of 75.3%, a positive predictive value of 28.5%, and a negative predictive value of 94.1%. CONCLUSION: The shortened VMS-based screening instrument showed to be of good prognostic value for hospitalization and 90-day mortality. The prediction model for mortality showed promising results and will be further validated and optimized

The admission of very old patients to our intensive care units: a review

In this review, we discuss several aspects of the decision to admit very old intensive care patients (VOPs) and present national as well as international data concerning outcome of VOPs. A substantial proportion of VOPs will not survive hospitalisation (33 to 42% 30-day mortality) and various studies describe that up to 75% of the patients are suffering from a persisting or severe functional decline after hospital discharge. Many will not be discharged home. Moreover, many elderly patients prioritise ‘quality of life’ above ‘quantity of life’. Therefore, the available outcome data should be used to inform patients or their surrogate decision-makers and enable them to participate in shared decision-making concerning goals of care

Validation of the ADFICE_IT Models for Predicting Falls and Recurrent Falls in Geriatric Outpatients

Objectives: Before being used in clinical practice, a prediction model should be tested in patients whose data were not used in model development. Previously, we developed the ADFICE_IT models for predicting any fall and recurrent falls, referred as Any_fall and Recur_fall. In this study, we externally validated the models and compared their clinical value to a practical screening strategy where patients are screened for falls history alone. Design: Retrospective, combined analysis of 2 prospective cohorts. Setting and Participants: Data were included of 1125 patients (aged ≥65 years) who visited the geriatrics department or the emergency department. Methods: We evaluated the models' discrimination using the C-statistic. Models were updated using logistic regression if calibration intercept or slope values deviated significantly from their ideal values. Decision curve analysis was applied to compare the models’ clinical value (ie, net benefit) against that of falls history for different decision thresholds. Results: During the 1-year follow-up, 428 participants (42.7%) endured 1 or more falls, and 224 participants (23.1%) endured a recurrent fall (≥2 falls). C-statistic values were 0.66 (95% CI 0.63-0.69) and 0.69 (95% CI 0.65-0.72) for the Any_fall and Recur_fall models, respectively. Any_fall overestimated the fall risk and we therefore updated only its intercept whereas Recur_fall showed good calibration and required no update. Compared with falls history, Any_fall and Recur_fall showed greater net benefit for decision thresholds of 35% to 60% and 15% to 45%, respectively.Conclusions and Implications: The models performed similarly in this data set of geriatric outpatients as in the development sample. This suggests that fall-risk assessment tools that were developed in community-dwelling older adults may perform well in geriatric outpatients. We found that in geriatric outpatients the models have greater clinical value across a wide range of decision thresholds compared with screening for falls history alone.</p

Intracranial artery calcifications: Risk factors and association with cardiovascular disease and cognitive function

Background and aims: we know little about clinical outcomes of arterial calcifications. This study investigates the risk factors of intracranial artery calcifications and its association with cardiovascular disease and cognitive function. Methods: patients were recruited from a Dutch memory clinic, between April 2009 and April 2015. The intracranial internal carotid artery (iICA) and basilar artery were analysed on the presence of calcifications. Calcifications in the iICA were also assessed on severity and location in the tunica intima or tunica media. Using logistic regression, risk factors of intracranial artery calcifications were analysed, as well as the association of these calcifications with cardiovascular disease, cognitive function and type of cognitive disorder (including subjective cognitive impairment, mild cognitive impairment and dementia). Cognitive function was assessed with the Cambridge Cognitive Examination. Results: 1992 patients were included (median age: 78.2 years, ±40% male). The majority of patients had calcifications in the iICA (±95%). Basilar artery calcifications were less prevalent (±8%). Risk factors for cerebral intracranial calcifications were age (p < 0.001), diabetes mellitus (medial iICA, p = 0.004), hypertension (intimal iICA, p < 0.001) and basilar artery, p = 0.019) and smoking (intimal iICA, p = 0.008). iICA calcifications were associated with stroke and intimal calcifications also with myocardial infarction. Intracranial artery calcifications were not associated with cognitive function or type of cognitive disorder. Conclusion: the majority of memory clinic patients had intracranial artery calcifications. Cardiovascular risk factors are differentially related to medial or intimal iICA calcifications. iICA calcifications were associated with myocardial infarction and stroke, but not with cognitive outcomes

Amount and Distribution of Intracranial Calcification in Symptomatic and Asymptomatic Primary Familial Brain Calcification

BACKGROUND AND OBJECTIVES: In clinical practice, it can be difficult to differentiate between intracranial calcifications related to primary familial brain calcification (PFBC) or aging. Also, little is known about the consequences of the amount of intracranial calcifications in patients with PFBC. Therefore, we aimed to compare the amount and distribution of intracranial calcifications in persons with PFBC with controls and between asymptomatic and symptomatic PFBC cases. METHODS: This was a case-control study including patients with PFBC and controls. Controls received a CT of the brain because of a trauma and had at least some basal ganglia calcification. The Nicolas score and volume of calcification were used to quantify intracranial calcifications on the CT scans. Receiver operating characteristic curves were obtained to calculate optimal cutoff points to discriminate between cases and controls. Mann-Whitney U tests and logistic regression, adjusted for age and sex, were used to compare the amount of calcification. RESULTS: Twenty-eight cases (median age 65 years, 50.0% male) and 90 controls (median age 74 years, 46.1% male) were included. Calcification scores were higher in cases (median volume: 4.91 cm 3 against 0.03 cm 3, p < 0.001, median Nicolas score: 26.5 against 2.0, p < 0.001) than controls. Calcifications were also more diffusely distributed in cases. To differentiate between cases and controls, optimal cutoff points were ≥0.2 cm 3 for the calcification volume and ≥6.0 for the Nicolas score. Calcification was higher for symptomatic than asymptomatic cases (calcification volume: 13.62 cm 3 against 1.61 cm 3, p = 0.01, Nicolas score: 39.0 against 15.5, p = 0.02). After adjustment for age and sex, the Nicolas score remained significantly higher in symptomatic patients, and the calcification volume did not. DISCUSSION: Patients with PFBC had more severe intracranial calcifications, and these calcifications were more diffusely distributed through the brain compared with controls. Symptomatic patients with PFBC might have more intracranial calcifications than asymptomatic persons

Impact of geriatric co-management on outcomes in hospitalised cardiology patients aged 85 and over

OBJECTIVE: Cardiovascular disease and frailty are common among the population aged 85+. We hypothesised these patients might benefit from geriatric co-management, as has been shown in other frail patient populations. However, there is limited evidence supporting geriatric co-management in older, hospitalised cardiology patients. METHODS: A retrospective cohort study was performed in a large teaching hospital in the Netherlands. We compared patients aged 85 and over admitted to the cardiology ward before (control group) and after the implementation of standard geriatric co-management (intervention group). Data on readmission, mortality, length of stay, number of consultations, delirium, and falls were analysed. RESULTS: The data of 1163 patients were analysed (n = 542 control, n = 621 intervention). In the intervention group, 251 patients did not receive the intervention because of logistic reasons or the treating physician's decision. Baseline characteristics were comparable in the intervention and control groups. Patients in the intervention group had a shorter length of stay (-1 day, p = 0.01) and were more often discharged to a geriatric rehabilitation facility (odds ratio [OR] 1.97, 95% confidence interval [CI] 1.10-3.54, p = 0.02) compared with the control patients. Other outcomes were not significantly different between the groups. CONCLUSIONS: After implementation of standard geriatric co-management for hospitalised cardiology patients aged 85 and over, the length of hospital stay shortened and the number of patients discharged to a geriatric rehabilitation facility increased. The adherence to geriatric team recommendations was high. Geriatric co-management would appear to optimise care for older hospitalised patients with cardiac disease

Prevalence and Association of Basal Ganglia Calcifications and Depressive Symptoms in Patients With Mild Cognitive Impairment or Dementia

AIM: The aim of this study is to investigate the association between basal ganglia calcification (BGC) and depressive symptoms within older adults with mild cognitive impairment (MCI) or dementia. METHODS: For this cross-sectional study, we included patients with MCI or dementia who visited the memory clinic between April 2009 and April 2015. All patients underwent a standard diagnostic workup, including assessment of depressive symptoms with the Geriatric Depression Scale and computed tomography imaging of the brain. Computed tomography scans were assessed for presence and severity of BGC. To analyse the association between BGC and depressive symptoms, binary logistic regression models were performed with adjustment for age, sex, cardiovascular risk factors, and cardiovascular diseases. RESULTS: In total, 1054 patients were included (median age: 81.0 y; 39% male). BGC was present in 44% of the patients, of which 20% was classified as mild, 20% as moderate, and 4% as severe. There were 223 patients (21%) who had a Geriatric Depression Scale score indicative of depressive symptoms. No association was found between the presence or severity of BGC and depressive symptoms. CONCLUSIONS: Although both BGC and depressive symptoms were common in patients with MCI or dementia, no association was demonstrated between the presence or severity of BGC and depressive symptoms

Assessment instruments in frail older patients:a call for more standardisation

OBJECTIVE: To determine the frequency and background of the use of assessment instruments for the Comprehensive Geriatric Assessment by clinical geriatricians and internists in geriatric medicine; the secondary aim was to make an inventory of the willingness to standardise the assessment instruments used.DESIGN: A descriptive questionnaire study.METHOD: In December 2016, we sent out a digital questionnaire (Survey Monkey) to all the hospitals in the Netherlands. Respondents were asked which instruments they used for specific domains of the Comprehensive Geriatric Assessment, what their choice of instruments was based on, if these instruments had added value, and if they were prepared to change the instruments they used.RESULTS: We received 66 responses (response: 82%). The most frequently-used instruments were: Mini Mental State Examination in combination with the clock drawing test (21%), Geriatric Depression Scale-15 (45%), Katz Index of Independence in Activities of Daily Living-6 (75%), Lawton and Brody (48%), Mini Nutritional Assessment(-short form) (outpatient; 56%) and Short Nutritional Assessment Questionnaire (inpatient: 36%), Experienced Burden Informal Care (46%), Charlson Comorbidity Index (35%), Timed Up and Go (76%), and the Safety Management System (VMS) fall risk question (21%). The most frequently used instruments were used in a large number of hospitals (35-97%).The variation of tests was the greatest in the domains of cognition, malnutrition, and mobility/physical functioning. Many respondents saw the added value of a consensus set of instruments (median: 70%; interquartile range (IQR): 50-86), and most were willing to change the instruments they use (median: 80%; IQR: 65-90).CONCLUSION: This inventory shows that the instruments used in most domains were reasonably uniform. Taking the willingness to change into account, a national set of basis instruments seems to be an achievable aim.</p

The Association between Intracranial Calcifications and Symptoms in Patients with Primary Familial Brain Calcification

(1) Background: Primary Familial Brain Calcification (PFBC) is a neurodegenerative disease characterized by bilateral calcifications of the basal ganglia and other intracranial areas. Many patients experience symptoms of motor dysfunction and cognitive disorders. The aim of this study was to investigate the association between the amount and location of intracranial calcifications with these symptoms. (2) Methods: Patients with suspected PFBC referred to our outpatient clinic underwent a clinical work-up. Intracranial calcifications were visualized on Computed Tomography (CT), and a Total Calcification Score (TCS) was constructed. Logistic and linear regression models were performed. (3) Results: Fifty patients with PFBC were included in this study (median age 64.0 years, 50% women). Of the forty-one symptomatic patients (82.0%), 78.8% showed motor dysfunction, and 70.7% showed cognitive disorders. In multivariate analysis, the TCS was associated with bradykinesia/hypokinesia (OR 1.07, 95%-CI 1.02-1.12, p < 0.01), gait ataxia (OR 1.06, 95%-CI 1.00-1.12, p = 0.04), increased fall risk (OR 1.04, 95%-CI 1.00-1.08, p = 0.03), and attention/processing speed disorders (OR 1.06, 95%-CI 1.01-1.12, p = 0.02). Calcifications of the lentiform nucleus and subcortical white matter were associated with motor and cognitive disorders. (4) Conclusions: cognitive and motor symptoms are common among patients with PFBC, and there is an association between intracranial calcifications and these symptoms
