Systematically reviewing all the available evidence and then creating summary analyses of the pooled data is the foundation of evidence-based practice. Indeed, this evidence synthesis approach informs much of the care of older adults in hospital and community. It is perhaps no surprise that the journal Age and Ageing is a frequent platform for publishing research papers based on systematic review and synthesis. This research has evolved substantially from the early days of evidence-based medicine and the Cochrane Collaboration. The traditional approach would be a quantitative summary, calculated using pair-wise meta-analysis of randomised controlled trials of drug versus placebo, or a synthesis of observational studies to create summaries of prevalence, associations and outcomes. Methods have evolved and newer techniques such as scoping reviews, test accuracy meta-analysis and qualitative synthesis are all now available. The sophistication of these methods is driven in part by the increasingly complex decisions that need be made in contemporary older adult care. Age and Ageing continues to champion established and novel evidence synthesis approaches, and in the accompanying Collection exemplars of these differing methods are presented and described. Whilst there is marked heterogeneity in the techniques used, the consistent and defining feature of all these papers is the desire to comprehensively, and critically summarise the evidence in order to answer the most pertinent questions regarding older adult care.

Background and Aim The aim of this systematic review was to quantify the association between frailty and COVID-19 in relation to mortality in hospitalised patients. Methods Medline, Embase, Web of Science and the grey literature were searched for papers from inception to 10 September 2020; the search was re-run in Medline up until the 9 December 2020. Screening, data extraction and quality grading were undertaken by two reviewers. Results were summarised using descriptive statistics, including a meta-analysis of overall mortality; the relationships between frailty and COVID-19 mortality were summarised narratively. Results A total of 2,286 papers were screened resulting in 26 being included in the review. Most studies were from Europe, half from the UK, and one from Brazil; the median sample size was 242.5, median age 73.1 and 43.5% were female. In total, 22/26 used the Clinical Frailty Scale; reported mortality ranged from 14 to 65%. Most, but not all studies showed an association between increasing frailty and a greater risk of dying. Two studies indicated a sub-additive relationship between frailty, COVID-19 and death, and two studies showed no association. Conclusions Whilst the majority of studies have shown a positive association between COVID-19-related death and increasing frailty, some studies suggested a more nuanced understanding of frailty and outcomes in COVID-19 is needed. Clinicians should exert caution in placing too much emphasis on the influence of frailty alone when discussing likely prognosis in older people with COVID-19 illness. [ABSTRACT FROM AUTHOR]

Background Declines in cardiorespiratory fitness (CRF) and muscle mass are both associated with advancing age and each of these declines is associated with worse health outcomes. Resistance exercise training (RET) has previously been shown to improve muscle mass and function in the older population. If RET is also able to improve CRF, as it has been shown to do in younger populations, it has the potential to improve multiple health outcomes in the expanding older population. Methods This systematic review aimed to identify the role of RET for improving CRF in healthy older adults. A search across CINAHL, MEDLINE, EMBASE and EMCARE databases was conducted with meta-analysis performed on eligible papers to identify improvements in established CRF parameters (VO2 peak, aerobic threshold (AT), 6-minute walking distance test (6MWT) following RET intervention. Main eligibility criteria included older adults (aged over 60), healthy cohorts (disease-specific cohorts were excluded) and RET intervention. Results Thirty-seven eligible studies were identified. Meta-analysis revealed a significant improvement in VO2 peak (MD 1.89 ml/kg/min; 95% confidence interval (CI) 1.21–2.57 ml/kg/min), AT (MD 1.27 ml/kg/min; 95% CI 0.44–2.09 ml/kg/min) and 6MWT (MD 30.89; 95% CI 26.7–35.08) in RET interventions less than 24 weeks. There was no difference in VO2 peak or 6MWT in interventions longer than 24 weeks. Discussion This systematic review adds to a growing body of evidence supporting the implementation of RET in the older population for improving whole-body health, particularly in time-limited timeframes.

Background frailty is common in older adults and associated with poor outcomes following illness. Although stroke is predominantly a disease of older people, our knowledge of frailty in stroke is limited. We aimed to collate the literature on acute stroke and frailty to estimate the prevalence of pre-stroke frailty and its associations with outcomes. Methods paired researchers searched multidisciplinary electronic databases for papers describing frailty and acute stroke. We assessed risk of bias using Newcastle-Ottawa tools appropriate to study design. We created summary estimates of pre-stroke frailty using random effects models. We collated whether studies reported significant positive associations between frailty and clinical outcomes in adjusted models. Results we included 14 studies (n  = 27,210 participants). Seven studies (n  = 8,840) used a frailty index approach, four studies (n  = 14,924) used Hospital Frailty Risk Scores. Pooled prevalence of pre-stroke frailty was 24.6% (95% confidence interval, CI: 16.2–33.1%; low quality evidence, downgraded due to heterogeneity, bias). Combining frailty and pre-frailty (nine studies, n  = 23,827), prevalence of any frailty syndrome was 66.8% (95%CI: 49.9–83.7%). Seven studies were at risk of bias, from participant selection or method of frailty assessment. Pre-stroke frailty was associated with all adverse outcomes assessed, including longer-term mortality (positive association in 6 of 6 studies reporting this outcome; odds ratio: 3.75 [95%CI: 2.41–5.70]), length of admission (3 of 4 studies) and disability (4 of 6 studies). Conclusions despite substantial heterogeneity, whichever way it is measured, frailty is common in patients presenting with acute stroke and associated with poor outcomes. This has implications for the design of stroke services and pathways. [ABSTRACT FROM AUTHOR]

The frailty index (FI) quantifies frailty as deficit accumulation. It has been adapted to employ laboratory test data (FI-Lab). Our objective was to systematically review and meta-analyse the FI-Lab's ability to predict mortality. Secondary objectives were to review the FI-Lab's association with adverse health outcomes and whether FI-Lab scores differed between the sexes. A systematic literature search was carried out using six online databases to identify studies that measured the FI-Lab in humans. Hazard ratios (HRs) were combined in a meta-analysis to create a pooled risk estimate for mortality. Of the 1,201 papers identified, spanning January 2010 until 11 July 2022, 38 were included. FI-Lab scores per 0.01 unit increase predicted mortality overall (HR = 1.04; 95% confidence interval (CI) = 1.03–1.05) and for studies with a mean age of 81+ years (HR = 1.04; 95% CI = 1.03–1.05). The quality of evidence for these meta-analyses are moderate and high, respectively. Further, higher FI-Lab scores were associated with more frequent adverse health outcomes. Sex differences in FI-Lab scores varied, with no consistent indication of a sex effect. The FI-Lab is associated with mortality and with a variety of adverse health outcomes. No consistent sex differences in FI-Lab scores were observed, with several studies in disagreement. Notably, these conclusions were most relevant to older (65+ years old) individuals; further evidence in younger people is needed in both clinical and population representative studies.

Introduction Neuromuscular electrical stimulation (NMES) is a treatment to prevent or reverse acquired disability in hospitalised adults. We conducted a systematic review and meta-analysis of its effectiveness. Method We searched MEDLINE, EMBASE, Cumulative Index to Nursing & Allied Health (CINAHL) and the Cochrane library. Inclusion criteria: randomised controlled trials of hospitalised adult patients comparing NMES to control or usual care. The primary outcome was muscle strength. Secondary outcomes were muscle size, function, hospital length of stay, molecular and cellular biomarkers, and adverse effects. We assessed risk of bias using the Cochrane risk-of-bias tool. We used Review Manager (RevMan) software for data extraction, critical appraisal and synthesis. We assessed certainty using the Grading of Recommendations Assessment, Development and Evaluation tool. Results A total of 42 papers were included involving 1,452 participants. Most studies had unclear or high risk of bias. NMES had a small effect on muscle strength (moderate certainty) (standardised mean difference (SMD) = 0.33; P  < 0.00001), a moderate effect on muscle size (moderate certainty) (SMD = 0.66; P  < 0.005), a small effect on walking performance (moderate certainty) (SMD = 0.48; P  < 0.0001) and a small effect on functional mobility (low certainty) (SMD = 0.31; P  < 0.05). There was a small and non-significant effect on health-related quality of life (very low certainty) (SMD = 0.35; P  > 0.05). In total, 9% of participants reported undesirable experiences. The effects of NMES on length of hospital stay, and molecular and cellular biomarkers were unclear. Conclusions NMES is a promising intervention component that might help to reduce or prevent hospital-acquired disability. [ABSTRACT FROM AUTHOR]

Background: ambulatory blood pressure monitoring (ABPM) may be helpful for the management of hypertension, but little is known about its tolerability in people with dementia. Objective: to review the published evidence to determine the tolerability of ABPM in people with dementia. Methods: English language search conducted in MEDLINE and EMBASE, using Ambulatory blood pressure' AND 'Dementia' (and associated synonyms) from 1996 to March 2015. Inclusion criteria: people diagnosed with dementia AND in whom blood pressure was measured using ABPM. The initial search was undertaken using title and abstract reviews, with selected papers being agreed for inclusion by two reviewers. Potentially eligible papers were assessed, and high-quality papers were retained. Two reviewers agreed the abstracted data for analysis. Meta-analysis was used to combine results across studies. Results: of the 221 screened abstracts, 13 studies (6%) met inclusion criteria, 5 had sufficient data and were of sufficient quality, involving 461 participants, most of whom had mild--moderate dementia. 77.7% (95% CI 62.2-93.2%) were able to tolerate ABPM; agreement with office BP was moderate to weak (two studies only--coefficients 0.3-0.38 for systolic blood pressure and 0.11-0.32 for diastolic blood pressure). One study compared home BP monitoring by a relative or ambulatory BP monitoring with office BP measures and found high agreement (ϗ 0.81). The little available evidence suggested increased levels of dementia being associated with reduced tolerability. Conclusions: ABPM is well tolerated in people with mild-moderate dementia and provides some additional information over and above office BP alone. However, few studies have addressed ABPM in people with more severe dementia. [ABSTRACT FROM AUTHOR]

Background: weak grip strength is a key component of sarcopenia and is associated with subsequent disability and mortality. We have recently established life course normative data for grip strength in Great Britain, but it is unclear whether the cut points we derived for weak grip strength are suitable for use in other settings. Our objective was to investigate differences in grip strength by world region using our data as a reference standard. Methods: we searched MEDLINE and EMBASE for reporting age- and gender-stratified normative data for grip strength. We extracted each item of normative data and converted it on to a Z-score scale relative to our British centiles. We performed meta-regression to pool the Z-scores and compare them by world region. Findings: our search returned 806 abstracts. Sixty papers met inclusion criteria and reported on 63 different samples. Seven UN regions were represented, although most samples (n = 44) were based in developed regions. We extracted 726 normative data items relating to 96,537 grip strength observations. Normative data from developed regions were broadly similar to our British centiles, with a pooled Z-score 0.12 SDs (95% CI: 0.07, 0.17) above the corresponding British centiles. By comparison, normative data from developing regions were clearly lower, with a pooled Z-score of -0.85 SDs (95% CI: -0.94, -0.76). Interpretation: our findings support the use of our British grip strength centiles and their associated cut points in consensus definitions for sarcopenia and frailty across developed regions, but highlight the need for different cut points in developing regions.

Background the prevalence of adverse drug reactions (ADRs) in hospitalised older patients, their clinical presentations, causative drugs, severity, preventability and measurable outcomes are unclear, ADRs being an increasing challenge to older patient safety. Methods we systematically searched PubMed, Embase, EBSCO-CINAHL, the Cochrane Library, 'rey' literature and relevant systematic review bibliographies, published from database inception to March 2020. We included any study reporting occurrence of in-hospital ADRs as primary or secondary outcomes in hospitalised older adults (mean age ≥ 65 years). Two authors independently extracted relevant information and appraised studies for bias. Study characteristics, ADR clinical presentations, causative drugs, severity, preventability and clinical outcomes were analysed. Study estimates were pooled using random-effects meta-analytic models. Results from 2,399 abstracts, we undertook full-text screening in 286, identifying 27 studies (29 papers). Final analysis yielded a pooled ADR prevalence of 16% (95%CI 12–22%, I 2 98%, τ 2 0.8585), in a population of 20,153 hospitalised patients aged ≥65 years of whom 2,479 patients experienced ≥ one ADR. ADR ascertainment was highly heterogeneous. Almost 48.3% of all ADRs involved five presentations: fluid/electrolyte disturbances (17.3%), gastrointestinal motility/defaecation disorders (13.3%), renal disorders (8.2%), hypotension/blood pressure dysregulation disorders/shock (5.5%) and delirium (4.1%). Four drug classes accounted for 57.8% of causative medications i.e. diuretics (19.8%), anti-bacterials (14.8%), antithrombotic agents (12.2%) and analgesics (10.9%). Pooled analysis of severity was not feasible. Four studies reported the majority of ADRs as preventable (55–95%). Conclusions on average, 16% of hospitalised older patients experience significant ADRs, varying in severity and mostly preventable, with commonly prescribed drug classes accounting for most ADRs.

Introduction Anticholinergic medications block the neurotransmitter acetylcholine in the brain and peripheral nervous system. Many medications have anticholinergic properties, and the cumulative effect of these medications is termed anticholinergic burden. Increased anticholinergic burden can have short-term side effects such as dry mouth, blurred vision and urinary retention as well as long-term effects including dementia, worsening physical function and falls. Methods We carried out a systematic review (SR) with meta-analysis (MA) looking at randomised controlled trials addressing interventions to reduce anticholinergic burden in older adults. Results We identified seven papers suitable for inclusion in our SR and MA. Interventions included multi-disciplinary involvement in medication reviews and deprescribing of AC medications. Pooled data revealed no significant difference in outcomes between control and intervention group for falls (OR = 0.76, 95% CI: 0.52–1.11, n  = 647), cognition (mean difference = 1.54, 95% CI: −0.04 to 3.13, n  = 405), anticholinergic burden (mean difference = 0.04, 95% CI: −0.11 to 0.18, n  = 710) or quality of life (mean difference = 0.04, 95% CI: −0.04 to 0.12, n  = 461). Discussion Overall, there was no significant difference with interventions to reduce anticholinergic burden. As we did not see a significant change in anticholinergic burden scores following interventions, it is likely other outcomes would not change. Short follow-up time and lack of training and support surrounding successful deprescribing may have contributed. [ABSTRACT FROM AUTHOR]

Background Depression is common in people with cognitive impairment but the effect of cognitive training in the reduction of depression is still uncertain. Aims The purpose of this paper is to evaluate the effect of cognitive training interventions in the reduction of depression rating scale score in people with cognitive impairment. Methods Literature searches were conducted via OVID databases. Randomized controlled trials (RCTs) evaluated the effect of cognitive training interventions for the reduction of depression rating scale score in people with mild cognitive impairment (MCI) or dementia were included. Mean difference (MD) with 95% confidence interval (CI) was used to combine the results of Geriatric Depression Scale (GDS). Standardized mean difference (SMD) was used to combine the results of different depression rating scales. Subgroup analyses were conducted according to the types of cognitive training and severity of cognitive impairment, i.e. MCI and dementia. Results A total of 2551 people with MCI or dementia were extracted from 36 RCTs. The baseline mean score of GDS-15 was 4.83. Participants received cognitive training interventions had a significant decrease in depression rating scale score than the control group (MD of GDS-15 = -1.30, 95% CI = -2.14–−0.47; and SMD of eight depression scales was −0.54 (95% CI = −0.77–−0.31). In subgroup analyses, the effect size of computerized cognitive training and cognitive stimulation therapy were medium-to-large and statistically significant in the reduction of depression rating scale score. Conclusions Cognitive training interventions show to be a potential treatment to ameliorate depression in people with cognitive impairment. [ABSTRACT FROM AUTHOR]

Background people in prison often experience poor health. Those aged 50 and over are the fastest growing age-group in prison and present particular challenges to criminal justice systems around the world. Non-communicable diseases (NCDs) account for two-thirds of deaths globally and no estimate of the prevalence of NCDs in this vulnerable population exists. Methods we searched PubMed, Medline, CINAHL, EMBASE and Global Health databases to identify original research papers that met our pre-defined inclusion criteria. No date or language restrictions were applied. Two authors undertook full-text screening as well as quality assessment and data extraction for all included studies. A random effects model was used to calculate pooled prevalence of any disease that was reported in two or more articles. Results the initial search identified 2,712 articles. 119 underwent full-text screening with 26 meeting the inclusion criteria. This provided prevalence data on 28 NCDs in 93,862 individuals from prisons in 11 countries. Pooled prevalence for the most significant NCDs was a follows; cancer 8% (95% CI 6–10%), cardiovascular disease 38% (95% CI 33–42%), hypertension 39% (95% CI 32–47%), diabetes 14% (95% CI 12–16%), COPD prevalence estimates ranged from 4% to 18%. Heterogeneity across studies was high. Conclusions those in prison over 50 years of age experience a high burden of NCDs which is often higher than younger prison and age-matched community peers. This health inequality is influenced by lifestyle, environmental and societal factors. Prison services should be adapted to serve the needs of this growing population. [ABSTRACT FROM AUTHOR]

Objective: hip fracture is a common and serious condition associated with high mortality. This study aimed to identify pre-operative characteristics which are associated with an increased risk of mortality after hip fracture surgery.Design: systematic search of published and unpublished literature databases, including EMBASE, MEDLINE, AMED, CINAHL, PubMed and the Cochrane Library, was undertaken to identify all clinical studies on pre-operative predictors of mortality after surgery in hip fracture with at least 3-month follow-up. Data pertaining to the study objectives was extracted by two reviewers independently. Where study homogeneity was evidence, a meta-analysis of pooled relative risk and 95% confidence intervals was performed for mortality against pre-admission characteristics.Results: fifty-three studies including 544,733 participants were included. Thirteen characteristics were identified as possible pre-operative indicators for mortality. Following meta-analysis, the four key characteristics associated with the risk of mortality up to 12 months were abnormal ECG (RR: 2.00; 95% CI: 1.45, 2.76), cognitive impairment (RR: 1.91; 95% CI: 1.35, 2.70), age >85 years (RR: 0.42; 95% CI: 0.20, 0.90) and pre-fracture mobility (RR: 0.13; 95% CI: 0.05, 0.34). Other statistically significant pre-fracture predictors of increased mortality were male gender, being resident in a care institution, intra-capsular fracture type, high ASA grade and high Charlson comorbidity score on admission.Conclusions: this review has identified the characteristics of patients with a high risk of mortality after a hip fracture surgery beyond the peri-operative period who may benefit from comprehensive assessment and appropriate management.PROSPERO Registration Number: CRD42012002107.

Scope: it has been suggested that overweight/obesity as a risk factor for incident dementia differs between mid-life and later life. We performed a systematic review and meta-analysis ofthe up-to-date current literature to assess this. Search Methods: inclusion criteria included epidemiological longitudinal studies published up to September 2014, in participants without cognitive impairment based on evidence of cognitive assessment and aged 30 or over at baseline assessment with at least 2 years of follow-up. Pubmed, Medline, EMBASE, PsychInfo and the Cochrane Library were searched using combinations of the search terms: Dementia, Alzheimer disease, Vascular Dementia, Multi-Infarct Dementia, Cognitive decline, Cognitive impairment, Mild Cognitive Impairment/Obesity, Overweight, Adiposity, Waist circumference (limits: humans, English language). Handsearching of all papers meeting the inclusion criteria was performed. A random-effects model was used for the meta-analysis. Results: ofthe 1,612 abstracts identified and reviewed, 21 completely met the inclusion criteria. Being obese below the age of 65 years had a positive association on incident dementia with a risk ratio (RR) 1.41 (95% confidence interval, CI: 1.20-1.66), but the opposite was seen in those aged 65 and over, RR 0.83 (95% CI: 0.74-0.94). Conclusions: this systematic review and meta-analysis suggests a positive association between obesity in mid-life and later dementia but the opposite in late life. Whether weight reduction in mid-life reduces risk is worthy of further study. [ABSTRACT FROM AUTHOR]

Introduction The prevalence of frailty at population level is unclear. We examined this in population-based studies, investigating sources of heterogeneity. Methods PubMed, Embase, CINAHL and Cochrane Library databases were searched for observational population-level studies published between 1 January 1998 and 1 April 2020, including individuals aged ≥50 years, identified using any frailty measure. Prevalence estimates were extracted independently, assessed for bias and analysed using a random-effects model. Results In total, 240 studies reporting 265 prevalence proportions from 62 countries and territories, representing 1,755,497 participants, were included. Pooled prevalence in studies using physical frailty measures was 12% (95% CI = 11–13%; n  = 178), compared with 24% (95% CI = 22–26%; n  = 71) for the deficit accumulation model (those using a frailty index, FI). For pre-frailty, this was 46% (95% CI = 45–48%; n  = 147) and 49% (95% CI = 46–52%; n  = 29), respectively. For physical frailty, the prevalence was higher among females, 15% (95% CI = 14–17%; n  = 142), than males, 11% (95% CI = 10–12%; n  = 144). For studies using a FI, the prevalence was also higher in females, 29% (95% CI = 24–35%; n  = 34) versus 20% (95% CI = 16–24%; n  = 34), for males. These values were similar for pre-frailty. Prevalence increased according to the minimum age at study inclusion. Analysing only data from nationally representative studies gave a frailty prevalence of 7% (95% CI = 5–9%; n  = 46) for physical frailty and 24% (95% CI = 22–26%; n  = 44) for FIs. Conclusions Population-level frailty prevalence varied by classification and sex. Data were heterogenous and limited, particularly from nationally representative studies making the interpretation of differences by geographic region challenging. Common methodological approaches to gathering data are required to improve the accuracy of population-level prevalence estimates. Protocol registration PROSPERO-CRD42018105431.

Background the number of older people living in residential and nursing care homes is rising. Loneliness is a major problem for older people, but little is known about the prevalence of loneliness amongst older people living in care homes. Aim to undertake a systematic review of literature on the prevalence of moderate and severe loneliness amongst older people living in residential and nursing care homes. Design we systematically reviewed the databases Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, PsycINFO, Embase, Scopus, Cochrane and Allied and Complementary Medicine Database (AMED) from inception to January 2019. We included all studies reporting data on the prevalence of loneliness amongst older people living in care homes. A random-effects meta-analysis was conducted on all eligible data. Results a total of 13 articles were included, representing 5,115 participants (age range of 55–102 years, mean age 83.5 years, 68% female). There was a significant variation between studies in estimates of prevalence. The prevalence of moderate loneliness ranged from 31 to 100%, and the prevalence of severe loneliness ranged from 9 to 81%. The estimated mean prevalence of 'moderate loneliness' was 61% (95% confidence interval (CI): 0.41, 0.80). The estimated mean prevalence of 'severe loneliness' was 35% (95% CI: 0.14, 0.60). Conclusion the prevalence of both moderate loneliness and severe loneliness amongst care home residents is high enough to warrant concern. However, the significant variation in prevalence estimates warrants further research. Future studies should identify which interventions can address loneliness and promote meaningful social engagement to enhance quality of life in care homes. [ABSTRACT FROM AUTHOR]

Introduction Anticoagulation of elderly patients with Atrial Fibrillation (AF) and falls remains a domain of contention amongst clinicians. There is limited evidence to guide long-term anticoagulation decision in such patients. We performed a systematic-review and meta-analysis to guide anticoagulation decision. Methods We conducted a prospectively registered systematic-review and meta-analysis (PROSPERO: CRD42021228661). Studies investigating patients >65 years of age anticoagulated for AF at risk of falls were included. Outcomes included were stroke/systemic embolism (SSE), CNS bleeds, major non-CNS bleeds, and mortality. CENTRAL, MEDLINE, PsycINFO, CINAHL, DARE, Web of science and Scopus were searched. Two authors performed paper inclusion/exclusion, data extraction, risk of bias and GRADE assessment. Data was pooled quantitatively using random-effects models and expressed as Odds Ratio (OR) and 95% Confidence Intervals (95%CI). Results Nine studies were included and five were combined quantitatively. Studies had low to moderate risk of bias. Anticoagulated fallers were at higher risk of SSE (OR = 1.73, 95%CI:1.21–2.47, p = 0.003), CNS bleeds (OR = 1.67, 95%CI:1.25–2.23, p < 0.001), major bleeds (OR = 1.87, 95%CI:1.66–2.11, p < 0.001) and mortality (OR = 1.96, 95%CI:1.71–2.25, p < 0.001) compared to anticoagulated non-fallers. Anticoagulated fallers were at higher risk of major bleeds compared to fallers not on anticoagulation (OR = 1.69, 95%CI:1.03–2.77, p = 0.04). However, there was no statistically significant difference in SSE, CNS bleeds or mortality. In fallers, Direct Oral Anticoagulants (DOACs) have lower risk of CNS bleeds (OR = 0.19, 95%CI:0.09–0.041, p < 0.001) and major bleeds (OR = 0.78, 95%CI:0.60–1.01, p = 0.06) compared to warfarin. There was no statistically significant difference in SSE or mortality between the anticoagulants. Conclusion: (s) Falling on anticoagulation is associated with increased risk of complications. However, only risk of major non-CNS bleeds increases when anticoagulating fallers. In fallers, DOACs appear safer than warfarin for bleeding complications. There remains paucity of evidence about anticoagulation in fallers (GRADE certainty = very low—moderate). Further evidence is needed to help clinicians and patients regarding anticoagulation.

Objective to investigate the impact of the availability and supply of social care on healthcare utilisation (HCU) by older adults in high income countries. Design systematic review and meta-analysis. Data sources medline, EMBASE, Scopus, Health Management Information Consortium, Cochrane Database of Systematic Reviews, NIHR Health Technology Assessment, NHS Economic Evaluation Database, Database of Abstracts of Reviews of Effectiveness, SCIE Online and ASSIA. Searches were carried out October 2016 (updated April 2017 and May 2018). (PROSPERO CRD42016050772). Study selection observational studies from high income countries, published after 2000 examining the relationship between the availability of social care (support at home or in care homes with or without nursing) and healthcare utilisation by adults >60 years. Studies were quality assessed. Results twelve studies were included from 11,757 citations; ten were eligible for meta-analysis. Most studies (7/12) were from the UK. All reported analysis of administrative data. Seven studies were rated good in quality, one fair and four poor. Higher social care expenditure and greater availability of nursing and residential care were associated with fewer hospital readmissions, fewer delayed discharges, reduced length of stay and expenditure on secondary healthcare services. The overall direction of evidence was consistent, but effect sizes could not be confidently quantified. Little evidence examined the influence of home-based social care, and no data was found on primary care use. Conclusions adequate availability of social care has the potential to reduce demand on secondary health services. At a time of financial stringencies, this is an important message for policy-makers.

Background computerised interventions have been suggested as an effective strategy to reduce potentially inappropriate prescribing (PIP) for hospitalised older adults. This systematic review and meta-analysis examined the evidence for efficacy of computerised interventions designed to reduce PIP in this patient group. Methods an electronic literature search was conducted using eight databases up to October 2017. Included studies were controlled trials of computerised interventions aiming to reduce PIP in hospitalised older adults (≥65 years). Risk of bias was assessed using Cochrane’s Effective Practice and Organisation of Care criteria. Results of 653 records identified, eight studies were included—two randomised controlled trials, two interrupted time series analysis studies and four controlled before–after studies. Included studies were mostly at a low risk of bias. Overall, seven studies showed either a statistically significant reduction in the proportion of patients prescribed a potentially inappropriate medicine (PIM) (absolute risk reduction {ARR} 1.3–30.1%), or in PIMs ordered (ARR 2–5.9%). However, there is insufficient evidence thus far to suggest that these interventions can routinely improve patient-related outcomes. It was only possible to include three studies in the meta-analysis—which demonstrated that intervention patients were less likely to be prescribed a PIM (odds ratio 0.6; 95% CI 0.38, 0.93). No computerised intervention targeting potential prescribing omissions (PPOs) was identified. Conclusions this systematic review concludes that computerised interventions are capable of statistically significantly reducing PIMs in hospitalised older adults. Future interventions should strive to target both PIMs and PPOs, ideally demonstrating both cost-effectiveness data and clinically significant improvements in patient-related outcomes.

Background community-based complex interventions for older adults have a variety of names, including Comprehensive Geriatric Assessment, but often share core components such as holistic needs assessment and care planning. Objective to summarise evidence for the components and effectiveness of community-based complex interventions for improving older adults' independent living and quality of life (QoL). Methods we searched nine databases and trial registries to February 2022 for randomised controlled trials comparing complex interventions to usual care. Primary outcomes included living at home and QoL. Secondary outcomes included mortality, hospitalisation, institutionalisation, cognitive function and functional status. We pooled data using risk ratios (RRs) or standardised mean differences (SMDs) with 95% confidence intervals (CIs). Results we included 50 trials of mostly moderate quality. Most reported using holistic assessment (94%) and care planning (90%). Twenty-seven (54%) involved multidisciplinary care, with 29.6% delivered mainly by primary care teams without geriatricians. Nurses were the most frequent care coordinators. Complex interventions increased the likelihood of living at home (RR 1.05; 95% CI 1.00–1.10; moderate-quality evidence) but did not affect QoL. Supported by high-quality evidence, they reduced mortality (RR 0.86; 95% CI 0.77–0.96), enhanced cognitive function (SMD 0.12; 95% CI 0.02–0.22) and improved instrumental activities of daily living (ADLs) (SMD 0.11; 95% CI 0.01–0.21) and combined basic/instrumental ADLs (SMD 0.08; 95% CI 0.03–0.13). Conclusions complex interventions involving holistic assessment and care planning increased the chance of living at home, reduced mortality and improved cognitive function and some ADLs.

Background Delirium is a common complication clinically and is associated with the poor outcomes, yet it is frequently unrecognised and readily disregarded. Although the 3-minute diagnostic interview for confusion assessment method-defined delirium (3D-CAM) has been used in a variety of care settings, a comprehensive evaluation of its accuracy in all available care settings has not been performed. Objective This study aimed to evaluate the diagnostic test accuracy of the 3D-CAM in delirium detection through a systematic review and meta-analysis. Methods We systematically searched PubMed, EMBASE, the Cochrane Library, Web of Science, CINAHL (EBSCO) and ClinicalTrials.gov published from inception to 10 July 2022. The quality assessment of the diagnostic accuracy studies-2 tool was applied to evaluate methodological quality. A bivariate random effects model was used to pool sensitivity and specificity. Results Seven studies with 1,350 participants and 2,499 assessments were included, which were carried out in general medical wards, intensive care units, internal medical wards, surgical wards, recovery rooms and post-anaesthesia care units. The prevalence of delirium ranged from 9.1% to 25%. The pooled sensitivity and specificity were 0.92 (95% confidence interval [CI] 0.87–0.95) and 0.95 (95% CI 0.92–0.97), respectively. The pooled positive likelihood ratio was 18.6 (95% CI 12.2–28.2), the negative likelihood ratio was 0.09 (95% CI 0.06–0.14) and the diagnostic odds ratio was 211 (95% CI 128–349). Moreover, the area under the curve was 0.97 (95% CI 0.95–0.98). Conclusions The 3D-CAM has good diagnostic accuracy for delirium detection in different care settings. Further analyses illustrated that it had comparable diagnostic accuracy in older adults and patients with dementia or known baseline cognitive impairment. In conclusion, the 3D-CAM is recommended for clinical delirium detection. [ABSTRACT FROM AUTHOR]

Introduction The incidence of major trauma in older people is increasing. Frailty is likely to be a factor that influences the outcomes of trauma. We conducted a systematic review aiming to investigate whether frailty affects major trauma outcomes in older people and whether it is more predictive than age. Methods Observational studies investigating frailty, major trauma severity and outcomes were eligible. We searched electronic databases (Ovid MEDLINE, PubMed, Ovid EMBASE and CINAHL) from 2010 to 01 January 2023. We used Joanna Briggs Institute software to assess the risk of bias and conduct meta-analyses of the relationships between frailty status and outcomes. We used a narrative synthesis to compare the predictive value of frailty and age. Results Twelve studies were eligible for meta-analyses. In-hospital mortality (odds ratio (OR) = 1.12, 95% confidence interval (CI) 1.05, 1.19), length of stay (OR = 2.04, 95% CI 1.51, 2.56), discharge to home (OR = 0.58, 95% CI 0.53, 0.63) and in-hospital complications (OR = 1.17, 95% CI 1.10, 1.24) were all associated with frailty. Frailty was found to be a more consistent predictor of adverse outcomes and mortality in older trauma patients than injury severity and age in six studies that reported multivariate regression analysis. Discussion Older trauma patients with frailty have higher in-hospital mortality rates, prolonged hospital stays, in-hospital complications and adverse discharge disposition. Frailty is a better predictor of adverse outcomes than age in these patients. Frailty status is likely to be a useful prognostic variable in guiding patient management and stratifying clinical benchmarks and research trials. [ABSTRACT FROM AUTHOR]

Background The 16-item Falls Efficacy Scale International (FES-I) is widely used to assess concerns-about-falling. Variants include 7-item Short FES-I, 30-item Iconographical Falls Efficacy Scale (Icon FES) and 10-item short Icon FES. No comprehensive systematic review and meta-analysis has been conducted to synthesise evidence regarding the measurement properties of these tools. Objectives To conduct a systematic review and meta-analysis of the measurement properties of four FES-I variants. Methods MEDLINE, Embase, CINAHL Plus, PsycINFO and Web of Science were searched systematically and articles were assessed for eligibility independently. The methodological quality of eligible studies was assessed using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist. The quality of measurement properties was assessed using COSMIN criteria for good measurement properties. Where possible, meta-analysis was conducted; otherwise, narrative synthesis was performed. Overall certainty of evidence was rated using a modified Grading of Recommendations, Assessment, Development and Evaluation system approach. Results The review included 58 studies investigating measurement properties of the four instruments. There was high-quality evidence to support internal consistency, reliability and construct validity of all instruments. Moderate- to high-certainty evidence suggests one-factor structure of FES-I with two underlying dimensions, one-factor structure of Short FES-I and two-factor structure of Icon FES. There was high-certainty evidence to support the responsiveness of FES-I, with further research needed for the other instruments. Conclusion There is evidence for excellent measurement properties of all four instruments. We recommend the use of these tools with healthy older people and people at a greater risk of falls due to conditions that might affect mobility and balance. [ABSTRACT FROM AUTHOR]

Introduction: Detection of delirium in hospitalised older adults is recommended in national and international guidelines. The 4 ‘A’s Test (4AT; www.the4AT.com) is a short (<2 min) instrument for delirium detection that is used internationally as a standard tool in clinical practice. We performed a systematic review and meta-analysis of diagnostic test accuracy of the 4AT for delirium detection. Methods: We searched the following electronic databases through Ovid: MEDLINE, Embase, and PsycINFO. Additional databases were searched: CINAHL (EBSCOhost), clinicaltrials.gov and Cochrane Central Register of Controlled Trials from 2011 (4AT publication) until 21 December 2019. Inclusion criteria: older adults (≥65) across any setting of care except critical care; validation study of the 4AT against a delirium reference standard (standard diagnostic criteria or validated tool). Two reviewers independently screened abstracts and papers and performed the data extraction. Pooled estimates of sensitivity and specificity were generated from a bivariate random effects model. Results: 17 studies (n = 3,701 observations) were included. Various settings including acute medicine, surgery, stroke wards and the emergency department were represented. The overall prevalence of delirium was 24.2% (95% CI 17.8–32.1%; range 10.5–61.9%). The pooled sensitivity was 0.88 (95% CI 0.80–0.93) and the pooled specificity was 0.88 (95% CI 0.82–0.92). The methodological quality of studies was mostly good. Conclusions: The 4AT is now supported by a substantial evidence base comparable to other well-studied tools such as the Confusion Assessment Method (CAM). The strong pooled sensitivity and specificity findings for the 4AT in this meta-analysis along with its brevity and lack of need for specific training provide support for its use as an effective assessment tool for delirium.

Background: two popular operational definitions of frailty, the frailty phenotype and Frailty index (FI), are based on different theories. Although FI was shown to be superior in predicting mortality to the frailty phenotype, no meta-analysis on mortality risk according to FI has been found in the literature. Methods: an electronic systematic literature search was conducted in August 2016 using four databases (Embase, Medline, CINAHL and PsycINFO) for prospective cohort studies published in 2000 or later, examining the mortality risk according to frailty measured by FI. A meta-analysis was performed to synthesise pooled mortality risk estimates. Results: of 2,617 studies identified by the systematic review, 18 cohorts from 19 studies were included. Thirteen cohorts showed hazard ratios (HRs) per 0.01 increase in FI, six cohorts showed HRs per 0.1 increase in FI and two cohorts each showed odds ratios (ORs) per 0.01 and 0.1 increase in FI, respectively. All meta-analyses suggested that higher FI was significantly associated with higher mortality risk (pooled HR per 0.01 FI increase = 1.039, 95% CI = 1.033-1.044, P < 0.001; pooled HR per 0.1 FI increase = 1.282, 95% CI = 1.258-1.307, P < 0.001; pooled OR per 0.01 FI increase = 1.054, 95% CI = 1.040-1.068, P < 0.001; pooled OR per 0.1 FI increase = 1.706, 95% CI = 1.547-1.881, P < 0.001). Meta-regression analysis among 13 cohorts with HR per 0.01 increase in FI showed that the studies with shorter follow-up periods and with lower female proportion were associated with higher mortality risks by FI. Conclusions: this systematic review and meta-analysis was the first to quantitatively demonstrate that frailty measured by the FI is a significant predictor of mortality. [ABSTRACT FROM AUTHOR]

Background and objective: the study analysed the effectiveness and safety of warfarin use compared with warfarin nonuse and non-vitamin K antagonist oral anticoagulants (NOACs) in atrial fibrillation (AF) patients aged ≥65 years. Methods: after searching PubMed and the Cochrane Library, 26 studies were included, with 10 comparing warfarin with warfarin non-use and 16 comparing warfarin with NOACs, in older AF patients (≥65 years). Results: warfarin use was superior to no antithrombotic therapy [relative risk (RR) 0.59, 95% confidence interval (CI) 0.51--0.76, I² = 12.3%, n = 8] and aspirin (RR 0.44, 95% CI 0.24-0.64, I² = 0.0%, n = 5) for stroke/thromboembolism (TE) prevention. Warfarin use was associated with a non-significant increase in risk of major bleeding compared with no antithrombotic therapy (RR 1.26, 95% CI 0.99--1.52, I² = 0.0%, n = 7) and aspirin (RR 1.20, 95% CI 0.91-1.50, I² = 0.0%, n = 5). NOACs were superior to warfarin for stroke/TE prevention [hazard ratio (HR) 0.81, 95% CI 0.73-0.89, I² = 56.6%, n = 9], and also were associated with reduced risk of major bleeding compared to warfarin (HR 0.87, 0.77-0.97, I² = 86.1%, n = 9). Conclusions: warfarin use was superior to warfarin non-use, aspirin and no antithrombotic therapy in reducing the risk of stroke/TE in older AF patients, but with a possible increase in major bleeding. NOACs were superior to warfarin for stroke/TE prevention, with reduced risk of major bleeding. [ABSTRACT FROM AUTHOR]

Background Gait impairment contributes to falls and frailty. Some studies suggest that cerebral small vessel disease (CSVD) is associated with gait impairment in the general population. We systematically reviewed and meta-analysed the literature on associations of CSVD with gait impairment and falls. Methods The protocol was published in PROSPERO (CRD42021246009). Searches of Medline, Cochrane and Embase databases were conducted on 30 March 2022. Cross-sectional and longitudinal studies of community-dwelling adults were included, reporting relationships between diagnosis or neuroimaging markers of CSVD and outcomes related to gait or falls. Partial correlation coefficients were calculated and pooled using a random-effects model for meta-analysis. Results The search retrieved 73 studies (53 cross-sectional; 20 longitudinal). Most studies reported an association between CSVD and gait impairments or falls risk: 7/7 studies on CSVD score or diagnosis, 53/67 studies on white matter hyperintensities (WMHs), 11/21 studies on lacunar infarcts, 6/15 studies on cerebral microbleeds and 1/5 studies on perivascular spaces. Meta-analysis of 13 studies found that higher WMH volume was mildly correlated with lower gait speed, in all studies (r  = −0.23, 95% confidence interval: −0.33 to −0.14, P  < 0.0001). However, there was significant heterogeneity between studies (I 2 = 82.95%; tau2 = 0.02; Q  = 79.37, P  < 0.0001), which was unexplained by variation in age, sex, study quality or if the study adjusted for age. Conclusions Findings suggest that CSVD severity is associated with gait impairment, history of falls and risk of future falls. Prevention of CSVD should be part of a comprehensive public health strategy to improve mobility and reduce risk of falls in later life. [ABSTRACT FROM AUTHOR]

Background Long-term care facilities (LTCFs) were high-risk settings for COVID-19 outbreaks. Objective To assess the impacts of the COVID-19 pandemic on LTCFs, including rates of infection, hospitalisation, case fatality, and mortality, and to determine the association between control measures and SARS-CoV-2 infection rates in residents and staff. Method We conducted a systematic search of six databases for articles published between December 2019 and 5 November 2021, and performed meta-analyses and subgroup analyses to identify the impact of COVID-19 on LTCFs and the association between control measures and infection rate. Results We included 108 studies from 19 countries. These studies included 1,902,044 residents and 255,498 staff from 81,572 LTCFs, among whom 296,024 residents and 36,807 staff were confirmed SARS-CoV-2 positive. The pooled infection rate was 32.63% (95%CI: 30.29 ~ 34.96%) for residents, whereas it was 10.33% (95%CI: 9.46 ~ 11.21%) for staff. In LTCFs that cancelled visits, new patient admissions, communal dining and group activities, and vaccinations, infection rates in residents and staff were lower than the global rate. We reported the residents' hospitalisation rate to be 29.09% (95%CI: 25.73 ~ 32.46%), with a case-fatality rate of 22.71% (95%CI: 21.31 ~ 24.11%) and mortality rate of 15.81% (95%CI: 14.32 ~ 17.30%). Significant publication biases were observed in the residents' case-fatality rate and the staff infection rate, but not in the infection, hospitalisation, or mortality rate of residents. Conclusion SARS-CoV-2 infection rates would be very high among LTCF residents and staff without appropriate control measures. Cancelling visits, communal dining and group activities, restricting new admissions, and increasing vaccination would significantly reduce the infection rates. [ABSTRACT FROM AUTHOR]

Background An optimal antithrombotic strategy for patients aged 80 years or older with atrial fibrillation (AF) remains elusive. Objective Using a systematic review with traditional and network meta-analysis, we investigated outcomes in AF patients ≥80 years treated with different antithrombotic strategies. Methods We searched eligible randomised controlled trials (RCTs) and observational studies from MEDLINE, EMBASE, Cochrane Library and Web of Science databases from inception to 16 December 2021. Research comparing treatment outcomes of novel oral anticoagulants (NOACs), aspirin, vitamin K antagonists (VKAs) or no oral anticoagulant/placebo therapy in patients ≥80 years with AF were included. Outcomes were stroke or systemic embolism (SSE), major bleeding, all-cause mortality, intracranial bleeding (ICH) and gastrointestinal bleeding. Traditional and network meta-analyses were performed. Net clinical benefit integrating SSE and major bleeding was calculated. Results Fifty-three studies were identified for analysis. In the meta-analysis of RCTs, risk of SSE (risk ratio [RR]: 0.82; 95% confidence interval [CI]: 0.73–0.99) and ICH (RR: 0.38; 95% CI: 0.28–0.52) was significantly reduced when NOACs were compared with VKAs. Network meta-analysis of RCTs demonstrated that edoxaban (P -score: 0.8976) and apixaban (P -score: 0.8528) outperformed other antithrombotic therapies by showing a lower major bleeding risk and better net clinical benefit. Both traditional and network meta-analyses from RCTs combining with observational studies showed consistent results. Conclusions In patients aged 80 years or older with AF, NOACs have better outcomes than VKAs regarding efficacy and safety profiles. Edoxaban and apixaban may be preferred treatment options since they are safer than other antithrombotic strategies. [ABSTRACT FROM AUTHOR]

Background regular physical exercise is essential to maintain or improve functional capacity in older adults. Multimorbidity, functional limitation, social barriers and currently, coronavirus disease of 2019, among others, have increased the need for home-based exercise (HBE) programmes and digital health interventions (DHI). Our objective was to evaluate the effectiveness of HBE programs delivered by DHI on physical function, health-related quality of life (HRQoL) improvement and falls reduction in older adults. Design systematic review and meta-analysis. Participants community-dwelling older adults over 65 years. Intervention exercises at home through DHI. Outcomes measures physical function, HRQoL and falls. Results twenty-six studies have met the inclusion criteria, including 5,133 participants (range age 69.5 ± 4.0–83.0 ± 6.7). The HBE programmes delivered with DHI improve muscular strength (five times sit-to-stand test, −0.56 s, 95% confidence interval, CI −1.00 to −0.11; P  = 0.01), functional capacity (Barthel index, 5.01 points, 95% CI 0.24–9.79; P  = 0.04) and HRQoL (SMD 0.18; 95% CI 0.05–0.30; P  = 0.004); and reduce events of falls (odds ratio, OR 0.77, 95% CI 0.64–0.93; P  = 0.008). In addition, in the subgroup analysis, older adults with diseases improve mobility (SMD −0.23; 95% CI −0.45 to −0.01; P  = 0.04), and balance (SMD 0.28; 95% CI 0.09–0.48; P  = 0.004). Conclusion the HBE programmes carried out by DHI improve physical function in terms of lower extremity strength and functional capacity. It also significantly reduces the number of falls and improves the HRQoL. In addition, in analysis of only older adults with diseases, it also improves the balance and mobility.

Background Delirium is a common neurocognitive disorder in hospitalised older adults with vast negative consequences. The predominant method of subtyping delirium is by motor activity profile into hypoactive, hyperactive and mixed groups. Objective This systematic review and meta-analysis investigated how predisposing factors differ between delirium motor subtypes. Methods Databases (Medline, PsycINFO, Embase) were systematically searched for studies reporting predisposing factors (prior to delirium) for delirium motor subtypes. A total of 61 studies met inclusion criteria (N  = 14,407, mean age 73.63 years). Random-effects meta-analyses synthesised differences between delirium motor subtypes relative to 22 factors. Results Hypoactive cases were older, had poorer cognition and higher physical risk scores than hyperactive cases and were more likely to be women, living in care homes, taking more medications, with worse functional performance and history of cerebrovascular disease than all remaining subtypes. Hyperactive cases were younger than hypoactive and mixed subtypes and were more likely to be men, with better cognition and lower physical risk scores than all other subtypes. Those with no motor subtype (unable to be classified) were more likely to be women and have better functional performance. Effect sizes were small. Conclusions Important differences in those who develop motor subtypes of delirium were shown prior to delirium occurrence. We provide robust quantitative evidence for a common clinical assumption that indices of frailty (institutional living, cognitive and functional impairment) are seen more in hypoactive patients. Motor subtypes should be measured across delirium research. Motor subtyping has great potential to improve the clinical risk assessment and management of delirium. [ABSTRACT FROM AUTHOR]

Background older adults living in long-term care (LTC) commonly suffer from anxiety symptoms and disorders. We completed a systematic review and meta-analysis to identify efficacious treatments for anxiety symptoms for older adults living in LTC. Methods we searched five electronic databases (MEDLINE, Embase, PsycINFO, Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials) to identify treatments for anxiety that have been trialled in LTC. Included studies had to be randomised trials, include residents of LTC, and measure anxiety symptoms as an outcome. Results the electronic search returned 6,617 articles, 519 were reviewed in full text, and 80 were included in the descriptive synthesis. Limited studies were meta-analysed (n  = 10) due to differences in described treatment and comparator conditions. Limited clinically relevant evidence supporting the use of pharmacologic treatments for symptoms of anxiety in LTC was identified. Of the treatments trialled, music compared with usual care (standardised mean difference, SMD: −0.82; 95% confidence interval (CI): −1.31, −0.34), music compared with social interaction (SMD: −0.41; 95% CI: −0.72, −0.10) and massage compared with usual care (SMD: −4.32; 95% CI: −7.44, −1.19) were found to improve anxiety symptoms, however, significant heterogeneity was detected in two comparisons. Conclusions a range of non-pharmacologic treatments that improved anxiety symptoms were identified for use in LTC. Although limited evidence exists to support the use of particular treatments, most non-pharmacologic treatments were low-risk interventions that may be readily implemented. Further research is required to assess the treatment effect on residents of LTC with anxiety disorders or clinically relevant symptoms at baseline. [ABSTRACT FROM AUTHOR]

Objective: osteoarthritis is a leading cause of disability. This systematic review aimed to establish the prevalence of depressive symptoms and anxiety among people with osteoarthritis in comparison to those without osteoarthritis. Method: we systematically reviewed databases including AMED, EMBASE, MEDLINE, PsycINFO, BNI, CINAHL and the Cochrane database library from their inception to January 2015. Studies presenting data on depressive symptoms and anxiety in people with osteoarthritis were included. A random- and fixed-effect meta-analysis was conducted on all eligible data. Results: a total of 49 studies were included, representing 15,855 individuals (59% women; mean age 65.2 years). The evidence base was moderate in quality. The pooled prevalence of depressive symptoms in osteoarthritis was 19.9% (95% confidence intervals (CI): 15.9-24.5%, n = 10,811). The corresponding pooled prevalence was 21.3% (95% CI: 15.5-28.5%; n=1,226) for anxiety symptoms. The relative risk of depression among people with osteoarthritis was 1.17 (95% CI 0.69-2.00, three studies, n = 941) compared with people without osteoarthritis. The relative risk of anxiety was 1.35 (95% CI: 0.51-3.59; three studies, n = 733) compared with those without osteoarthritis. Conclusion: one-fifth of people with osteoarthritis experience symptoms of depression and anxiety. However, it is uncertain whether this is increased compared with those without osteoarthritis, with no direct evidence to support an increase in anxiety and depression in osteoarthritis.

The author discusses the paper "Is Orthostatic Hypotension Related to Falling? A Meta-analysis of Individual Patient Data of Prospective Observational Studies," published in a 2017 issue of "Age Ageing." He details the symptoms of orthostatic hypotension (OH), which he describes as a condition in which a significant blood pressure drop occurs on standing upright from a recumbent position. He also describes the two analysis options within the meta-analysis of individual participant data (IPD).

Background Falls remain a common and debilitating problem in hospitals worldwide. The aim of this study was to investigate the effects of falls prevention interventions on falls rates and the risk of falling in hospital. Design Systematic review and meta-analysis. Participants Hospitalised adults. Intervention Prevention methods included staff and patient education, environmental modifications, assistive devices, policies and systems, rehabilitation, medication management and management of cognitive impairment. We evaluated single and multi-factorial approaches. Outcome measures Falls rate ratios (rate ratio: RaR) and falls risk, as defined by the odds of being a faller in the intervention compared to control group (odds ratio: OR). Results There were 43 studies that satisfied the systematic review criteria and 23 were included in meta-analyses. There was marked heterogeneity in intervention methods and study designs. The only intervention that yielded a significant result in the meta-analysis was education, with a reduction in falls rates (RaR = 0.70 [0.51–0.96], P  = 0.03) and the odds of falling (OR = 0.62 [0.47–0.83], P  = 0.001). The patient and staff education studies in the meta-analysis were of high quality on the GRADE tool. Individual trials in the systematic review showed evidence for clinician education, some multi-factorial interventions, select rehabilitation therapies, and systems, with low to moderate risk of bias. Conclusion Patient and staff education can reduce hospital falls. Multi-factorial interventions had a tendency towards producing a positive impact. Chair alarms, bed alarms, wearable sensors and use of scored risk assessment tools were not associated with significant fall reductions. [ABSTRACT FROM AUTHOR]

Evidence-based decisions on clinical and cost-effectiveness of interventions are ideally informed by meta-analyses of intervention trial data. However, when undertaken, such meta-analyses in ageing research have typically been conducted using standard methods whereby summary (aggregate) data are extracted from published trial reports. Although meta-analysis of aggregate data can provide useful insights into the average effect of interventions within a selected trial population, it has limitations regarding robust conclusions on which subgroups of people stand to gain the greatest benefit from an intervention or are at risk of experiencing harm. Future evidence synthesis using individual participant data from ageing research trials for meta-analysis could transform understanding of the effectiveness of interventions for older people, supporting evidence-based and sustainable commissioning. A major advantage of individual participant data meta-analysis (IPDMA) is that it enables examination of characteristics that predict treatment effects, such as frailty, disability, cognitive impairment, ethnicity, gender and other wider determinants of health. Key challenges of IPDMA relate to the complexity and resources needed for obtaining, managing and preparing datasets, requiring a meticulous approach involving experienced researchers, frequently with expertise in designing and analysing clinical trials. In anticipation of future IPDMA work in ageing research, we are establishing an international Ageing Research Trialists collective, to bring together trialists with a common focus on transforming care for older people as a shared ambition across nations.

Background the aim of this systematic review and meta-analysis was to update and synthesise the totality of research evidence on the effectiveness of acute geriatric unit (AGU) care for older adults admitted to hospital with acute medical complaints. Methods MEDLINE, CINAHL, CENTRAL and Embase databases were systematically searched from 2008 to February 2022. Screening, data extraction and quality grading were undertaken by two reviewers. Only trials with a randomised design comparing AGU care and conventional care units were included. Meta-analyses were performed in Review Manager 5.4 and the Grading of Recommendations, Assessment, Development and Evaluations framework was used to assess the certainty of evidence. The primary outcome was incidence of functional decline between baseline 2-week prehospital admission status and discharge and at follow-up. Results 11 trials recruiting 7,496 participants across three countries were included. AGU care resulted in a reduction in functional decline at 6-month follow-up (risk ratio (RR) 0.79, 95% confidence interval (CI) 0.66–0.93; moderate certainty evidence) and an increased probability of living at home at 3-month follow-up (RR 1.06, 95% CI 0.99–1.13; high certainty evidence). AGU care resulted in little or no difference in functional decline at hospital discharge or at 3-month follow-up, length of hospital stay, costs, the probability of living at home at discharge, mortality, hospital readmission, cognitive function or patient satisfaction. Conclusions AGU care improves clinical and process outcomes for hospitalised older adults with acute medical complaints. Future research should focus on greater inclusion of clinical and patient reported outcome measures. [ABSTRACT FROM AUTHOR]

Objective Depressive disorders are common in long-term care (LTC), however, there is no one process used to detect depressive disorders in this setting. Our goal was to describe the diagnostic accuracy of depression detection tools used in LTC settings. Methods We conducted a systematic review and meta-analysis of diagnostic accuracy measures. The databases PubMed, EMBASE, PsycINFO and CINAHL were searched from inception to 10 September 2021. Studies involving persons living in LTC, assisted living residences or facilities, comparing diagnostic accuracy of depression tools with a reference standard, were included. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool was used to assess risk of bias. Results We identified 8,463 citations, of which 20 studies were included in qualitative synthesis and 19 in meta-analysis. We identified 23 depression detection tools (including different versions) that were validated against a reference standard. At a cut-off point of 6 on the Geriatric Depression Scale-15 (GDS-15), the pooled sensitivity was 73.6% (95% confidence interval (CI) 43.9%–76.5%), specificity was 76.5% (95% CI 62.9%–86.7%), and an area under the curve was 0.83. There was significant heterogeneity in these analyses. There was insufficient data to conduct meta-analysis of other screening tools. The Nursing Homes Short Depression Inventory (NH-SDI) had a sensitivity ranging from 40.0% to 98.0%. The 4-item Cornell Scale for Depression in Dementia (CSDD) had the highest sensitivity (67.0%–90.0%) for persons in LTC living with dementia. Conclusions There are 23 tools validated for detection of depressive disorders in LTC, with the GDS-15 being the most studied. Tools developed specifically for use in LTC settings include the NH-SDI and CSDD-4, which provide briefer options to screen for depression. However, more studies of both are needed to examine tool accuracy using meta-analyses. [ABSTRACT FROM AUTHOR]

Long-term care (LTC) facilities, in which older adults are institutionalised, have the responsibility to address their residents' rights, privacy and comfort in expressing themselves sexually in an acceptable manner. However, many older adults have reported barriers in their sexual expression, which is often a result of the care staff's attitudes in the facilities. This review synthesis evidence from qualitative studies on the challenges faced by care staff when supporting sexual expression of older residents in LTC facilities. The systematic review and meta-synthesis is reported according to the Enhanced Transparency in Reporting the Synthesis of Qualitative Research Statement. A systematic literature search for peer-reviewed studies was conducted on PubMed, Cochrane Library, EMBASE, Scopus, Web of Science, PsycINFO, CINAHL and ProQuest Theses and Dissertations from inception until December 2020. Sandelowski and Barroso's two-step approach was used to synthesise the evidence. Seventeen qualitative studies published between 2004 and 2020 were included. This review encapsulated the experiences and challenges of 4,387 care staff whose age ranged from 18 to 69 years. Through the meta-synthesis, four themes were identified: varying manifestations of sexual expression and situations encountered, a spectrum of care staff's attitudes, setting boundaries in dementia care and workplace support. Managing sexual expression can be challenging for the care staff, given the complex interplay between personal beliefs, social contexts, moral dilemmas, practical barriers and the lack of clear policies. This review highlighted the need to equip them with knowledge, skills and confidence in managing sexuality in LTC facilities. [ABSTRACT FROM AUTHOR]

Background Post-hospital falls constitute a significant health concern for older adults who have been recently discharged from the hospital. Objectives To systematically summarise existing evidence on the incidence and risk factors for post-hospital falls among older adults. Methods A systematic review and meta-analysis was conducted. Six electronic databases were searched to identify cohort studies investigating the incidence and risk factors for post-hospital falls in older adults. The incidence and risk factors for post-hospital falls were extracted. The meta-analysis was used to calculate pooled incidences and 95% confidence intervals (CI). The meta-regression and subgroup meta-analysis were conducted to explore sources of heterogeneity in incidence proportions across the eligible studies. A qualitative synthesis was performed for the post-hospital falls risk factors. Results Eighteen studies from eight countries (n  = 9,080,568) were included. The pooled incidence proportion of any and recurrent post-hospital falls was 14% (95% CI: 13%–15%) and 10% (95% CI: 5%–14%), respectively. Follow-up period, study quality, study country, setting, percentage of female subjects, percentage of subjects with previous falls and the primary data collection method for falls significantly contributed to the 64.8% of the heterogeneity in incidence proportions. Twenty-six risk factors for post-hospital falls were identified in the eligible studies, where biological factors were the most commonly identified factors. The highest risks were reported for previous falls, previous fractures, delirium and neurological diseases. Conclusion The findings of this study suggested future post-hospital falls prevention should prioritise the needs of older adults with the dominant risk factors. Further investigations into the period-specific incidence and socioeconomic and environmental risk factors for post-hospital falls are also required. [ABSTRACT FROM AUTHOR]

Objective this study aimed to investigate how sarcopenia has been defined and measured in the literature reporting its prevalence, and how different definitions and measurement tools can affect prevalence estimates. Design systematic review and meta-analysis. Setting and participants community-dwelling older people. Methods meta-analysis of data collected from observational studies. We performed an electronic search in five databases to identify studies reporting the prevalence of sarcopenia. We used descriptive statistics to present data pertaining sarcopenia definition and measurement tools, and the quality-effects model for meta-analysis of pooled prevalence. Results we found seven different operational definitions for sarcopenia and a variety of tools applied to assess the sarcopenic markers; muscle mass, muscle strength and physical performance. The prevalence of sarcopenia varied between the definitions with general estimates ranging from 5% based on the European Working Group on Sarcopenia in Older People (EWGSOP1) criterion to 17% with the International Working Group on Sarcopenia. According to the tool used to assess muscle mass, strength and physical performance, prevalence values also varied within definitions extending from 1 to 7%, 1 to 12% and 0 to 22%, respectively. Conclusion and implications the criteria used to define sarcopenia, as well as the measurement tools applied to assess sarcopenic markers have influence in the prevalence of sarcopenia. The establishment of a unique definition for sarcopenia, the use of methods that guarantee an accurate evaluation of muscle mass and the standardisation of measurement tools are necessary to allow a proper diagnosis and comparison of sarcopenia prevalence among populations.

Objective Exercise prevents falls in the general older population, but evidence is inconclusive for older adults living with cognitive impairment. We performed an updated systematic review and meta-analysis to assess the potential effectiveness of interventions for reducing falls in older persons with cognitive impairment. Methods PubMed, EMBASE, CINAHL, Scopus, CENTRAL and PEDro were searched from inception to 10 November 2020. We included randomised controlled trials (RCTs) that evaluated the effects of physical training compared to a control condition (usual care, waitlist, education, placebo control) on reducing falls among community-dwelling older adults with cognitive impairment (i.e. any stage of Alzheimer's disease and related dementias, mild cognitive impairment). Results We identified and meta-analysed nine studies, published between 2013 and 2020, that included 12 comparisons (N = 1,411; mean age = 78 years; 56% women). Overall, in comparison to control, interventions produced a statistically significant reduction of approximately 30% in the rate of falls (incidence rate ratio = 0.70; 95% CI, 0.52-0.95). There was significant between-trial heterogeneity (I2 = 74%), with most trials (n = 6 studies [eight comparisons]) showing no reductions on fall rates. Subgroup analyses showed no differences in the fall rates by trial-level characteristics. Exercise-based interventions had no impact on reducing the number of fallers (relative risk = 1.01; 95% CI, 0.90–1.14). Concerns about risk of bias in these RCTs were noted, and the quality of evidence was rated as low. Conclusions The positive statistical findings on reducing fall rate in this meta-analysis were driven by a few studies. Therefore, current evidence is insufficient to inform evidence-based recommendations or treatment decisions for clinical practice. PROSPERO Registration number: CRD42020202094.

Background dance is a mind–body activity that stimulates neuroplasticity. We explored the effect of dance on cognitive function in older adults. Methods we searched MEDLINE, EMBASE, CENTRAL and PsycInfo databases from inception to August 2020 (PROSPERO:CRD42017057138). Inclusion criteria were (i) randomised controlled trials (ii) older adults (aged ≥ 55 years), (iii) intervention—dance and (iv) outcome—cognitive function. Cognitive domains were classified with the Diagnostic and Statistical Manual of Mental Disorders-5 Neurocognitive Framework. Meta-analyses were performed in RevMan5.3 and certainty of evidence with GradePro. Results we reviewed 3,997 records and included 11 studies (N  = 1,412 participants). Seven studies included only healthy older adults and four included those with mild cognitive impairment (MCI). Dance interventions varied in frequency (1–3×/week), time (35–60 minutes), duration (3–12 months) and type. We found a mean difference (MD) = 1.58 (95% confidence interval [CI) = 0.21–2.95) on the Mini Mental State Examination for global cognitive function (moderate-certainty evidence), and the Wechsler Memory Test for learning and memory had an MD = 3.02 (95% CI = 1.38–4.65; low-certainty evidence). On the Trail Making Test-A for complex attention, MD = 3.07 (95% CI = −0.81 to 6.95; high-certainty evidence) and on the Trail Making Test-B for executive function, MD = −4.12 (95% CI = −21.28 to 13.03; moderate-certainty evidence). Subgroup analyses did not suggest consistently greater effects in older adults with MCI. Evidence is uncertain for language, and no studies evaluated social cognition or perceptual–motor function. Conclusions dance probably improves global cognitive function and executive function. However, there is little difference in complex attention, and evidence also suggests little effect on learning and memory. Future research is needed to determine the optimal dose and if dance results in greater cognitive benefits than other types of physical activity and exercise. [ABSTRACT FROM AUTHOR]

Objective there may be age-related differences in the impact of weight change on health. This study systematically reviewed the evidence on the relationship between weight change and all-cause mortality in adults aged 65 years and older. Methods MEDLINE, EMBASE and CINAHL were searched from inception to 11 June 2020, PROSPERO CRD 42019142268. We included observational studies reporting on the association between weight change and all-cause mortality in older community-dwelling adults. A random-effects meta-analysis was performed to calculate pooled hazard ratios and scored based on the Agency for Healthcare Research and Quality guidelines. Results a total of 30 studies, including 1,219,279 participants with 69,255 deaths, demonstrated that weight loss was associated with a 59% increase in mortality risk (hazard ratio (HR): 1.59; 95% confidence interval (CI): 1.45–1.74; P  < 0.001). Twenty-seven studies that reported outcomes for weight gain (1,210,116 participants with 65,481 deaths) indicated that weight gain was associated with a 10% increase in all-cause mortality (HR: 1.10; 95%CI: 1.02, 1.17; P  = 0.01). Four studies investigated weight fluctuation (2,283 events among 6,901 participants), which was associated with a 63% increased mortality risk (HR: 1.66; 95%CI: 1.28, 2.15). No evidence of publication bias was observed (all P  > 0.05). Conclusion for community-dwelling older adults, weight changes (weight loss, gain or weight fluctuation) are associated with an increased risk of all-cause mortality risk relative to stable weight. Further research is needed to determine whether these associations vary depending upon initial weight, and whether or not the weight loss/gain was intentional. [ABSTRACT FROM AUTHOR]

Background a systematic review in 2015 showed kinematic gait and balance parameters which can discriminate patients with mild cognitive impairment (MCI) from cognitively healthy individuals. Objective this systematic review and meta-analysis aims to summarise and synthesise the evidence published after the previous review about the functional objective parameters obtained by an instrumented kinematic assessment which could discriminate patients with MCI from cognitively healthy individuals, as well as to assess the level of evidence per outcome. Methods major electronic databases were searched from inception to August 2019 for cross-sectional studies published after 2015 examining kinematic gait and balance parameters, which may discriminate patients with MCI from cognitively healthy individuals. Meta-analysis was carried out for each parameter reported in two or more studies. Results Ten cross-sectional studies with a total of 1,405 patients with MCI and 2,277 cognitively healthy individuals were included. Eight of the included studies reported a low risk of bias. Patients with MCI showed a slower gait speed than cognitively healthy individuals. Thus, single-task gait speed (d  = −0.44, 95%CI [−0.60 to −0.28]; P  < 0.001), gait speed at fast pace (d  = −0.48, 95%CI [−0.72 to −0.24]; P  < 0.001) and arithmetic dual-task gait speed (d  = −1.20, 95%CI [−2.12 to −0.28]; P  = 0.01) were the functional objective parameters which best discriminated both groups. Conclusion the present review shows kinematic gait parameters which may discriminate patients with MCI from cognitively healthy individuals. Most of the included studies reported a low risk of bias, but the grading of recommendations assessment, development and evaluation criteria showed a low level of evidence per outcome.

Background cognitive impairment is highly prevalent among older patients attending the Emergency Department (ED) and is associated with adverse outcomes. Methods we conducted a systematic review and meta-analysis to evaluate the diagnostic accuracy of cognitive screening instruments to rule out cognitive impairment in older patients in the ED. A comprehensive literature search was performed in MEDLINE, EMBASE, CINAHL and CENTRAL. A risk of bias assessment using QUADAS-2 was performed. Results 23 articles, examining 18 different index tests were included. Only seven index tests could be included in the meta-analysis. For ruling out cognitive impairment irrespective of aetiology, Ottawa 3 Day Year (O3DY) (pooled sensitivity 0.90; (95% CI) 0.71–0.97) had the highest sensitivity. Fourteen articles focused on screening for cognitive impairment specifically caused by delirium. For ruling out delirium, the 4 A's Test (4AT) showed highest sensitivity (pooled sensitivity 0.87, 95% confidence interval (95% CI) 0.74–0.94). Conclusions high clinical and methodological heterogeneity was found between included studies. Therefore, it is a challenge to recommend one diagnostic test for use as a screening instrument for cognitive impairment in the ED. The 4AT and O3DY seem most promising for ruling out cognitive impairment in older patients attending the ED. The review protocol was registered in PROSPERO (CRD42018082509). [ABSTRACT FROM AUTHOR]

Background Potentially inappropriate prescribing (PIP) may not have received as much attention in primary care settings (compared to tertiary hospital and nursing home settings), due to uncertainty about its prevalence in this healthcare setting. We conducted a systematic review with meta-analysis to summarise the prevalence of PIP specific to primary care settings and computed the population attributable risk (PAR) to estimate the impact of PIP in primary care. Method We searched PubMed, Embase, CINAHL, Web of Science, Scopus, PsycINFO and previous review articles for studies related to 'older persons', 'primary care' and 'inappropriate prescribing'. Two reviewers selected eligible articles, extracted data and evaluated risk of bias. Multilevel meta-analysis was conducted to pool the prevalence estimates across the included studies, while meta-regression was conducted to investigate the sources of heterogeneity. Results Of the 4,259 articles identified, we included 67 articles with 111 prevalence estimates and a total of 5,054,975 participants. Overall, PIP had a pooled prevalence of 33.3% (95% CI 29.7–37.0%). Based on population attributable risks, PIP explained 7.7–17.3% of adverse outcomes related to older persons in primary care. If current PIP prevalence is halved, 37–79 cases of adverse outcomes may potentially be prevented (per 1,000 adverse outcomes). Conclusions The findings demonstrate the relevance and potential impact of PIP specific to primary care settings. Given the increasingly central role that primary care plays in coordinating healthcare, the findings highlight the need to prioritise PIP intervention in primary care as a key strategy to reduce iatrogenic medication-related harm among older persons in current healthcare system.

Background Falls are a common occurrence and the most effective quality improvement (QI) strategies remain unclear. Methods We conducted a systematic review and network meta-analysis (NMA) to elucidate effective quality improvement (QI) strategies for falls prevention. Multiple databases were searched (inception−April 2017). We included randomised controlled trials (RCTs) of falls prevention QI strategies for participants aged ≥65 years. Two investigators screened titles and abstracts, full-text articles, conducted data abstraction and appraised risk of bias independently. Results A total of 126 RCTs including 84,307 participants were included after screening 10,650 titles and abstracts and 1210 full-text articles. NMA including 29 RCTs and 26,326 patients found that team changes was statistically superior in reducing the risk of injurious falls relative to usual care (odds ratio [OR] 0.57 [0.33 to 0.99]; absolute risk difference [ARD] −0.11 [95% CI, −0.18 to −0.002]). NMA for the outcome of number of fallers including 61 RCTs and 40 128 patients found that combined case management, patient reminders and staff education (OR 0.18 [0.07 to 0.47]; ARD −0.27 [95% CI, −0.33 to −0.15]) and combined case management and patient reminders (OR, 0.36 [0.13 to 0.97]; ARD −0.19 [95% CI, −0.30 to −0.01]) were both statistically superior compared to usual care. Conclusions Team changes may reduce risk of injurious falls and a combination of case management, patient reminders, and staff education, as well as case management and patient reminders may reduce risk of falls. Our results can be tailored to decision-maker preferences and availability of resources. Systematic review registration PROSPERO (CRD42013004151) [ABSTRACT FROM AUTHOR]

Background protein-energy malnutrition is a major health concern in home-dwelling older adults, particularly in the context of an ageing population. Therefore, a systematic review and meta-analysis was undertaken to determine the prevalence of malnutrition among older adults living independently in the community according to geographical region, sampling frame, rurality and sex. Methods six electronic databases were searched until September 2016. Original research studies which used the Mini Nutritional Assessment, Patient-Generated Subjective Global Assessment or Subjective Global Assessment to determine nutrition status in community samples with a mean age of ≥65 years were critically appraised and pooled using meta-analysis. Meta-regression was used to explore predictors of malnutrition prevalence in pooled statistics with high heterogeneity. Results 111 studies from 38 countries (n = 69,702 participants) were included. The pooled prevalence of malnutrition in the older community setting ranged from 0.8% (95% CI: 0.2–1.7%) in Northern Europe to 24.6% (95% CI: 0.0–67.9%) in South-East Asia. Of all sampling frames, participants receiving homecare services had the highest prevalence at 14.6% (95% CI: 9.9–20.0%). Malnutrition prevalence in rural communities (9.9%; 95% CI: 4.5–16.8%) was double that in urban communities (5.7%; 95% CI: 4.2–7.3%) and higher among females than males (odds ratio = 1.45 [95% CI: 1.27–1.66]; P < 0.00001). Conclusions the results of this review provide strategic insight to develop public and community health priorities for preventing malnutrition and associated poor health outcomes.
