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 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]

This systematic review evaluated the impact of oral probiotics on the immune response to vaccination in older people. A literature search was performed in three electronic databases up to January 2023. Randomised controlled trials (RCTs) conducted in older people (age ≥ 60 years) investigating oral probiotics and vaccine response outcomes were included. Characteristics and outcome data of the included studies were extracted and analysed and study quality was assessed using the Cochrane Risk of Bias Tool for randomised trials. Ten RCTs involving 1,560 participants, reported in 9 papers, were included. Nine studies involved the seasonal influenza vaccine and one a COVID-19 vaccine. All studies used lactobacilli, some in combination with bifidobacteria. Studies reported outcomes including anti-vaccine antibody titres or concentrations, seroconversion and seroprotection. When comparing antibody titres, seroprotection rate and seroconversion rate between probiotic and placebo groups expressed as a response ratio, the weighted mean values were 1.29, 1.16 and 2.00, respectively. Meta-analysis showed that probiotics increase seroconversion rates to all three strains of the seasonal influenza vaccine: odds ratio (95% confidence interval) 2.74 (1.31, 5.70; P  = 0.007) for the H1N1 strain; 1.90 (1.04, 3.44; P  = 0.04) for the H3N2 strain; 1.72 (1.05, 2.80; P  = 0.03) for the B strain. There was a low level of heterogeneity in these findings. Several studies were at high risk of bias due to missing outcome data. Lactobacilli may improve the vaccine response, but further research is needed to be more certain of this. [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.

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 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 Comprehensive geriatric assessment (CGA) has been in use for the last three decades. However, some doubts remain regarding its clinical use. Therefore, we aimed to capture the breadth of outcomes reported and assess the strength of evidence of the use of comprehensive geriatric assessment (CGA) for health outcomes in older persons. Methods Umbrella review of systematic reviews of the use of CGA in older adults searching in Pubmed, Embase, Scopus, Cochrane library and CINHAL until 05 November 2021. All possible health outcomes were eligible. Two independent reviewers extracted key data. The grading of evidence was carried out using the GRADE for intervention studies, whilst data regarding systematic reviews were reported as narrative findings. Results Among 1,683 papers, 31 systematic reviews (19 with meta-analysis) were considered, including 279,744 subjects. Overall, 13/53 outcomes were statistically significant (P  < 0.05). There was high certainty of evidence that CGA reduces nursing home admission (risk ratio [RR] = 0.86; 95% confidence interval [CI]: 0.75–0.89), risk of falls (RR = 0.51; 95%CI: 0.29–0.89), and pressure sores (RR = 0.46; 95%CI: 0.24–0.89) in hospital medical setting; decreases the risk of delirium (OR = 0.71; 95%CI: 0.54–0.92) in hip fracture; decreases the risk of physical frailty in community-dwelling older adults (RR = 0.77; 95%CI: 0.64–0.93). Systematic reviews without meta-analysis indicate that CGA improves clinical outcomes in oncology, haematology, and in emergency department. Conclusions CGA seems to be beneficial in the hospital medical setting for multiple health outcomes, with a high certainty of evidence. The evidence of benefits is less strong for the use of CGA in other settings. [ABSTRACT FROM AUTHOR]

Objective: to identify all published papers on risk factors and risk assessment tools for falls in hospital inpatients. To identify clinical risk assessment tools or individual clinical risk factors predictive of falls, with the ultimate aim of informing the design of effective fall prevention strategies. Design: systematic literature review (Cochrane methodology). Independent assessment of quality against agreed criteria. Calculation of odds ratios and 95% confidence intervals for risk factors and of sensitivity, specificity, negative and positive predictive value for risk assessment tools (with odds ratios and confidence intervals), where published data sufficient. Results: 28 papers on risk factors were identified, with 15 excluded from further analysis. Despite the identification of 47 papers purporting to describe falls risk assessment tools, only six papers were identified where risk assessment tools had been subjected to prospective validation, and only two where validation had been performed in two or more patient cohorts. Conclusions: a small number of significant falls risk factors emerged consistently, despite the heterogeneity of settings namely gait instability, agitated confusion, urinary incontinence/frequency, falls history and prescription of 'culprit' drugs (especially sedative/hypnotics). Simple risk assessment tools constructed of similar variables have been shown to predict falls with sensitivity and specificity in excess of 70%, although validation in a variety of settings and in routine clinical use is lacking. Effective falls interventions in this population may require the use of better-validated risk assessment tools, or alternatively, attention to common reversible falls risk factors in all patients.

Objectives The purpose of this paper is to investigate the utilisation of general practice Medicare Benefit Schedule (MBS) services aligned to Comprehensive Geriatric Assessment (CGA) within 6 months of an aged care eligibility assessment and its effects on mortality and transition to permanent residential aged care (PRAC). Design Retrospective cohort study from the Historical Cohort of the Registry of Senior Australians. Setting Community. Participants In total, 69,171 Individuals (aged 75+) receiving home care packages (HCPs) between 2011 and 2015. Outcome measures Mortality and transition to PRAC. Results The claims for a management plan with team care arrangement (TCA) within 3 months of the health assessment (i.e. CGA) was present in 5% and associated with 14% lower mortality (adjusted hazard ratio [aHR], 95%CI = 0.86, 0.80–0.93) compared to no claims, lower than that seen with partial CGA which was either health assessment claims only 7.0% (aHR, 95%CI = 0.93, 0.89–0.97) or management plan coupled with TCA claims only 9.0% (aHR, 95%CI = 0.91, 0.89–0.97). This pattern was seen in those frailer but not in those where the frailty index score was <0.21. Claims for management plans coupled with TCAs alone were associated with a 10% lower transition to PRAC (asHR, 95%CI = 0.90, 0.85–0.96) in those with FI score < 0.21 while this estimate was not significant in individuals with FI score ≥ 0.21. Conclusion It appears the conduct of a combination of interventions considered to be components of the CGA by GPs was associated with a lower risk of mortality that no claims or partial conduct of CGA.

Introduction: exposure to air pollution has been shown to increase risk of inflammatory processes and risk of cardiovascular mortality. Such exposure may therefore also be a risk factor for cognitive impairment/dementia. Method: a systematic review of the literature was conducted with databases searched using keywords for air pollution, cognitive decline and dementia. All identified abstracts and potentially relevant articles were double read. For those papers meeting the inclusion criteria, summary tables were prepared and papers quality assessed. Results: from 1,551 abstracts identified, 10 articles were retrieved of which two were rejected. Of the eight remaining six reported prevalent cognitive assessment with historical pollution exposure and two incident cognitive decline, also with historical pollution exposure. In general, an association was reported between exposure and poorer prevalent measures of cognitive function. Data were mixed for incident cognitive decline with one study finding an association and the other not. Reports were limited by a lack of detailed reporting, use of proxy measures of pollution exposure and a lack of clarity regarding cognitive testing methodology and analysis. Conclusion: this systematic review highlights that there is some evidence of a potential association between air pollution and subsequent cognitive decline. Further work is clearly required and longitudinal analysis of ongoing cohort studies or new research would add much needed clarity to this area. [ABSTRACT FROM AUTHOR]

Background COVID-19 has disproportionately affected older people. Objective The objective of this paper to investigate whether frailty is associated with all-cause mortality in older hospital inpatients, with COVID-19. Design Cohort study. Setting Secondary care acute hospital. Participants Participants included are 677 consecutive inpatients aged 65 years and over. Methods Cox proportional hazards models were used to examine the association of frailty with mortality. Frailty was assessed at baseline, according to the Clinical Frailty Scale (CFS), where higher categories indicate worse frailty. Analyses were adjusted for age, sex, deprivation, ethnicity, previous admissions and acute illness severity. Results Six hundred and sixty-four patients were classified according to CFS. Two hundred and seventy-one died, during a mean follow-up of 34.3 days. Worse frailty at baseline was associated with increased mortality risk, even after full adjustment (P  = 0.004). Patients with CFS 4 and CFS 5 had non-significant increased mortality risks, compared to those with CFS 1–3. Patients with CFS 6 had a 2.13-fold (95% CI 1.34–3.38) and those with CFS 7–9 had a 1.79-fold (95% CI 1.12–2.88) increased mortality risk, compared to those with CFS 1–3 (P  = 0.001 and 0.016, respectively). Older age, male sex and acute illness severity were also associated with increased mortality risk. Conclusions Frailty is associated with all-cause mortality risk in older inpatients with COVID-19.

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 older patients aged ≥65 years constitute the majority of the National Emergency Laparotomy Audit (NELA) population. To better understand this group and inform future service changes, this paper aims to describe patient characteristics, outcomes and process measures across age cohorts and temporally in the 4-year period (2014–2017) since NELA was established. Methods patient-level data were populated from the NELA data set years 1–4 and linked with Office of National Statistics mortality data. Descriptive data were compared between groups delineated by age, NELA year and geriatrician review. Primary outcomes were 30- and 90-day mortality, length of stay (LOS) and discharge to care-home accommodation. Results in total, 93,415 NELA patients were included in the analysis. The median age was 67 years. Patients aged ≥65 years had higher 30-day (15.3 versus 4.9%, P  < 0.001) and 90-day mortality (20.4 versus 7.2%, P  < 0.001) rates, longer LOS (median 15.2 versus 11.3 days, P  < 0.001) and greater likelihood of discharge to care-home accommodation compared with younger patients (6.7 versus 1.9%, P  < 0.001). Mortality rate reduction over time was greater in older compared with younger patients. The proportion of older NELA patients seen by a geriatrician post-operatively increased over years 1–4 (8.5 to 16.5%, P  < 0.001). Post-operative geriatrician review was associated with reduced mortality (30-day odds ratio [OR] 0.38, confidence interval [CI] 0.35–0.42, P  < 0.001; 90-day OR 0.6, CI 0.56–0.65, P  < 0.001). Conclusions older NELA patients have poorer post-operative outcomes. The greatest reduction in mortality rates over time were observed in the oldest cohorts. This may be due to several interventions including increased perioperative geriatrician input. [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.

Background: the care of older people with dementia is often complicated by physical comorbidity and polypharmacy, but the extent and patterns of these have not been well described. This paper reports analysis of these factors within a large, cross-sectional primary care data set. Methods: data were extracted for 291,169 people aged 65 years or older registered with 314 general practices in the UK, of whom 10,258 had an electronically recorded dementia diagnosis. Differences in the number and type of 32 physical conditions and the number of repeat prescriptions in those with and without dementia were examined. Age-gender standardised rates were used to calculate odds ratios (ORs) of physical comorbidity and polypharmacy. Results: people with dementia, after controlling for age and sex, had on average more physical conditions than controls (mean number of conditions 2.9 versus 2.4; P < 0.001) and were on more repeat medication (mean number of repeats 5.4 versus 4.2; P < 0.001). Those with dementia were more likely to have 5 or more physical conditions (age-sex standardised OR [sOR] 1.42, 95% confidence interval (CI) 1.35-1.50; P < 0.001) and were also more likely to be on 5 or more (sOR 1.46; 95% CI 1.40-1.52; P < 0.001) or 10 or more repeat prescriptions (sOR 2.01; 95% CI 1.90-2.12; P < 0.001). Conclusions: people with dementia have a higher burden of comorbid physical disease and polypharmacy than those without dementia, even after accounting for age and sex differences. Such complex needs require an integrated response from general health professionals and multidisciplinary dementia specialists. [ABSTRACT FROM AUTHOR]

Background frailty measurement may identify patients at risk of decline after hospital discharge, but many measures require specialist review and/or additional testing. Objective to compare validated frailty tools with routine electronic health record (EHR) data at hospital discharge, for associations with readmission or death. Design observational cohort study. Setting hospital ward. Subjects consented cardiology inpatients ≥70 years old within 24 hours of discharge. Methods patients underwent Fried, Short Physical Performance Battery (SPPB), PRISMA-7 and Clinical Frailty Scale (CFS) assessments. An EHR risk score was derived from the proportion of 31 possible frailty markers present. Electronic follow-up was completed for a primary outcome of 90-day readmission or death. Secondary outcomes were mortality and days alive at home ('home time') at 12 months. Results in total, 186 patients were included (79 ± 6 years old, 64% males). The primary outcome occurred in 55 (30%) patients. Fried (hazard ratio [HR] 1.47 per standard deviation [SD] increase, 95% confidence interval [CI] 1.18–1.81, P  < 0.001), CFS (HR 1.24 per SD increase, 95% CI 1.01–1.51, P  = 0.04) and EHR risk scores (HR 1.35 per SD increase, 95% CI 1.02–1.78, P  = 0.04) were independently associated with the primary outcome after adjustment for age, sex and co-morbidity, but the SPPB and PRISMA-7 were not. The EHR risk score was independently associated with mortality and home time at 12 months. Conclusions frailty measurement at hospital discharge identifies patients at risk of poorer outcomes. An EHR-based risk score appeared equivalent to validated frailty tools and may be automated to screen patients at scale, but this requires further validation. [ABSTRACT FROM AUTHOR]

Objective we aimed to investigate the association of smoking cessation with risk of all-cause mortality amongst oldest old people (aged ≥ 80 years). Design this was a prospective cohort study. Setting the Chinese Longitudinal Healthy Longevity Survey, implemented in 23 provinces of China. Participants a total of 28,643 community-dwelling oldest old people (mean age, 92.9 ± 7.5 years) were included. Methods in this community-based cohort study, Cox proportional hazards models were used to examine the association of smoking cessation with risk of all-cause mortality. Results during 136,585 person-years of follow-up from baseline to 1 September 2014, compared with never smokers, hazard ratios and 95% confidence intervals for all-cause mortality were 1.06 (1.02–1.10) for current smokers, 1.23 (1.09–1.39) for transient quitters (≤1 consecutive years since smoking cessation), 1.22 (1.12–1.32) for recent quitters (2–6 consecutive years since smoking cessation) and 1.11 (1.02–1.22) for long-term quitters (>6 consecutive years since smoking cessation). Cox models with penalised splines revealed an increased risk of all-cause mortality after smoking cessation; the highest mortality risk was observed within 2–4 years after smoking cessation and the risk gradually decreased with duration of smoking cessation. We further conducted subgroup analyses and sensitivity analyses to reduce the impact of reverse causation. Conclusions smoking is harmful to health in all populations. Our study findings indicated smoking cessation in late life to be associated with increased risk of all-cause mortality amongst oldest old people who have smoked for a long time.

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]

Background Following hip fracture surgery, patients from residential care are frequently excluded from inpatient rehabilitation. We aimed to assess the impact of place of residence and other factors such as frailty on rehabilitation outcomes after hip fracture surgery. Methods Retrospective cohort study. Outcome measures included Functional Independence Measure efficiency, discharge destination and recovery of pre-fracture mobility. Univariable and multivariable linear or logistic regression analyses were performed. Setting One general rehabilitation and two geriatric evaluation and management wards in a large public tertiary teaching hospital. Participants A total of 844 patients who underwent inpatient rehabilitation after hip fracture surgery from 2010 to 2018. Results There were 139 (16%) patients from residential care. Being from residential care was not an independent predictor of poor outcomes. Premorbid frailty (Clinical Frailty Scale) was the strongest independent predictor of poorer Functional Independence Measure efficiency, inability to recover pre-fracture mobility and return to community dwelling. Dementia and delirium were also independently predictive of poor outcomes across all measures. Age > 90 years was independently predictive of inability to recover pre-fracture mobility and return to community dwelling. Conclusion Being from residential care is not independently associated with poor outcomes following inpatient rehabilitation after hip fracture surgery and should not be the basis for excluding these patients from rehabilitation. Major predictors of poorer outcomes include premorbid frailty, dementia, delirium and age > 90 years. If able and motivated, those with potentially reversible functional limitations should be given the opportunity to participate in inpatient rehabilitation as even small gains can have a significant impact on quality of life.

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: while there is a trend towards a compression of disability, secular trends in physiological frailty have not been investigated. The aim of this paper was to report physiological frailty in two cohorts of 75-year olds examined in 1987 and 2005. Methods: a repeated cross-sectional study. Two population-based birth cohorts of community-dwelling 75-year olds from Gothenburg, Sweden, born in 1911-12 (n = 591) and 1930 (n = 637) were examined with identical methods in 1987 and 2005. Measures were three frailty criteria from Fried's frailty phenotype: low physical activity, slow gait speed and self-reported exhaustion. Results: seventy-five-year olds examined in 2005 were less frail according to the criteria low physical activity compared with those examined in 1987 (3 versus 18%, P < 0.001).This was seen both in women and in men, and among those with basic and more than basic educational level. Further, men with basic education were less frail in 2005 compared with those in 1987 in slow gait speed (non-significant when adjusted for body height) and low self-rated fitness, while no cohort differences were seen in men with more than basic education. Women with more than basic education were less frail in 2005 compared with those in 1987 in slow gait speed and self-rated fitness, while no cohort difference was seen in women with basic education. Conclusion: less 75-year olds were physiologically frail in 2005 compared with those in 1987, with the exception of women with low educational level, suggesting that this is a disadvantaged group that needs to receive particular attention with regard to physiological frailty.

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]

Background: concern over the sustainability of the National Health Service (NHS) is often focussed on rising numbers of hospital admissions, particularly among older people. Hospital admissions are enumerated routinely by the Hospital Episode Statistics (HES) Service, but published data do not allow individual-level service use to be explored. This study linked information on Hertfordshire Cohort Study (HCS) participants with HES inpatient data, with the objective of describing patterns and predictors of admissions among individuals.Methods: 2,997 community-dwelling men and women aged 59–73 years completed a baseline HCS assessment between 1998 and 2004; HES and mortality data to 31 March 2010 were linked with the HCS database. This paper describes patterns of hospital use among the cohort at both the admission and individual person level.Results: the cohort experienced 8,741 admissions; rates were 391 per 1,000 person-years among men (95% CI: 380, 402) and 327 among women (95% CI: 316, 338), P < 0.0001 for gender difference. A total of 1,187 men (75%) and 981 women (69%) were admitted to hospital at least once; among these, median numbers of admissions were 3 in men (inter-quartile range, (IQR): 1, 6) and 2 in women (IQR: 1, 5). Forty-eight percent of those ever admitted had experienced an emergency admission and 70% had been admitted overnight.Discussion: It is possible to link routinely collected HES data with detailed information from a cohort study. Hospital admission is common among community-dwelling ‘young-old’ men and women. These linked datasets will facilitate research into lifecourse determinants of hospital admission and inform strategies to manage demand on the NHS. [ABSTRACT FROM AUTHOR]

Background: inpatient falls are a major patient safety issue causing distress, injury and death. Systematic review suggests multifactorial assessment and intervention can reduce falls by 20–30%, but large-scale studies of implementation are few. This paper describes an extended evaluation of the FallSafe quality improvement project, which presented key components of multifactorial assessment and intervention as a care bundle.Methods: data on delivery of falls prevention processes were collected at baseline and for 18 months from nine FallSafe units and nine control units. Data on falls were collected from local risk management systems for 24 months, and data on under-reporting through staff surveys.Results: in FallSafe units, delivery of seven care bundle components significantly improved; most improvements were sustained after active project support was withdrawn. Twelve-month moving average of reported fall rates showed a consistent downward trend in FallSafe units but not controls. Significant reductions in reported fall rate were found in FallSafe units (adjusted rate ratio (ARR) 0.75, 95% confidence interval (CI) 0.68–0.84 P < 0.001) in the 12 months following full implementation but not in control units (ARR 0.91, 95% CI 0.81–1.03 P = 0.13). No significant changes in injurious fall rate were found in FallSafe units (ARR 0.86, 95% CI 0.71–1.03 P = 0.11), or controls (ARR 0.88, 95% CI 0.72–1.08 P = 0.13). In FallSafe units, staff certain falls had been reported increased from 60 to 77%.Conclusion: introducing evidence-based care bundles of multifactorial assessment and intervention using a quality improvement approach resulted in improved delivery of multifactorial assessment and intervention and significant reductions in fall rates, but not in injurious fall rates.

Background: the worldwide population is ageing. One expected consequence of this is an increase in morbidity and an associated increased demand for long-term care. Physical rehabilitation is beneficial in older people, but relatively little is known about effects in residents of long-term care facilities.Objective: to examine the effects of physical rehabilitation on activities of daily living (ADL) in elderly residents of long-term care facilities.Methods: systematic review with meta-analysis of randomised controlled trials. We included studies that compared the effect of a physical rehabilitation intervention on independence in ADL with either no intervention or an alternative intervention in older people (over 60 years) living in long-term care facilities. We searched 19 databases including the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, AMED, Web of Knowledge and Google Scholar. Two researchers independently screened papers and extracted data. Outcomes of included studies were combined in a standardised mean difference random-effects meta-analysis.Results: thirteen of 14 studies identified were included in the meta-analysis. Independence in ADL was improved by 0.24 standard units (95% CI: 0.11–0.38; P = 0.0005). This is equivalent to 1.3 points on the Barthel Index (0–20 scale). No significant differences in effect were found based on participant or intervention characteristics. Larger sample size and low attrition were associated with smaller estimates of effect. All studies were assessed to be at risk of bias.Conclusions: physical rehabilitation may improve independence for elderly long-term care facility residents, but mean effects are small. It is unclear which interventions are most appropriate. [ABSTRACT FROM AUTHOR]

Objective: we estimated the cost-effectiveness of a community falls prevention service compared with usual care from a National Health Service and personal social services perspective over the 12 month trial period.Design: a cost-effectiveness and cost utility analysis alongside a randomised controlled trialSetting: community.Participants: people over 60 years of age living at home or in residential care who had fallen and called an emergency ambulance but were not taken to hospital.Interventions: referral to community fall prevention services or usual health and social care.Measurements: incremental cost per fall prevented and incremental cost per Quality-Adjusted Life Years (QALYs)Results: a total of 157 participants (82 interventions and 75 controls) were used to perform the economic evaluation. The mean difference in NHS and personal social service costs between the groups was £-1,551 per patient over 1 year (95% CI: £-5,932 to £2,829) comparing the intervention and control groups. The intervention patients experienced on average 5.34 fewer falls over 12 months (95% CI: −7.06 to −3.62). The mean difference in QALYs was 0.070 (95% CI: −0.010 to 0.150) in favour of the intervention group.Conclusion: the community falls prevention service was estimated to be cost-effective in this high-risk group.

Background Incontinence is common in hospitalised older adults but few studies report new incidence during or following hospitalisation. Objective To describe prevalence and incidence of incontinence in older inpatients and associations with clinical outcomes. Design Secondary analysis of prospectively collected data from consecutive consenting inpatients age 65 years and older on medical and surgical wards in four Australian public hospitals. Methods Participants self-reported urinary and faecal incontinence 2 weeks prior to admission, at hospital discharge and 30 days after discharge as part of comprehensive assessment by a trained research assistant. Outcomes were length of stay, facility discharge, 30-day readmission and 6-month mortality. Results Analysis included 970 participants (mean age 76.7 years, 48.9% female). Urinary and/or faecal incontinence was self-reported in 310/970 (32.0%, [95% confidence interval (CI) 29.0–35.0]) participants 2 weeks before admission, 201/834 (24.1% [95% CI 21.2–27.2]) at discharge and 193/776 (24.9% [95% CI 21.9–28.1]) 30 days after discharge. Continence patterns were dynamic within the peri-hospital period. Of participants without pre-hospital incontinence, 74/567 (13.1% [95% CI 10.4–16.1) reported incontinence at discharge and 85/537 (15.8% [95% CI 12.8–19.2]) reported incontinence at 30 days follow-up. Median hospital stay was longer in participants with pre-hospital incontinence (7 vs. 6 days, P  = 0.02) even in adjusted analyses and pre-hospital incontinence was significantly associated with mortality in unadjusted but not adjusted analyses. Conclusion Pre-hospital, hospital-acquired and new post-hospital incontinence are common in older inpatients. Better understanding of incontinence patterns may help target interventions to reduce this complication. [ABSTRACT FROM AUTHOR]

Background Early in the COVID-19 pandemic, many experts pointed to potential adverse mental health effects for older adults. By contrast, many studies in young to middle-aged adults found older age to be associated with reduced mental burden. However, a systematic review on older adults is missing. Objectives To comprehensively assess the pandemic's mental health impact on older adults. Data sources We searched nine databases from December 2019 to April 2022. Study selection We included longitudinal and repeated cross-sectional studies assessing pre- and/or peri-pandemic mental distress and/or positive mental health indicators (e.g. wellbeing) on at least two occasions. Data synthesis We identified 108 studies comprising 102,136 participants (≥60 years). After removal of outliers, there was a small increase in mental distress from pre-to-peri-pandemic assessments, standardised mean difference (SMD) = 0.10, 95% confidence interval (CI) [0.01, 0.18]. Furthermore, a small peri-pandemic decrease in anxiety symptoms was observed, whereas other symptoms remained unchanged. For positive mental health indicators, wellbeing and quality of life showed an initial decrease, whereas overall positive mental health increased during the pandemic, SMD = 0.08, 95% CI [0.01, 0.15]. Being female was related to larger peri-pandemic increases in mental distress. Conclusions Based on many studies, this review demonstrated small decreases in mental health during early stages of the pandemic in older adults, with evidence for later recovery. These findings are similar to those for younger adults and correct earlier claims that older adults are at particular risk for negative mental health consequences. The results ask for further research into resilience and adaptation processes in older adults. [ABSTRACT FROM AUTHOR]

Background Long-term opioid use and associated adverse outcomes have increased dramatically in recent years. Limited research is available on long-term opioid use in older adults. Objective We aimed to determine the incidence and predictors of long-term or persistent opioid use (POU) amongst opioid-naïve older adults without a cancer diagnosis. Methods This was a retrospective cohort study using five national administrative healthcare databases in New Zealand. We included all opioid-naïve older adults (≥65 years) who were initiated on opioid therapy between January 2013 and June 2018. The outcome of interest was POU, defined as having continuously filled ≥1 opioid prescription within 91–180 days after the index opioid prescription. Multivariable logistic regression was used to examine the predictors of POU. Results The final sample included 268,857 opioid-naïve older adults; of these, 5,849(2.2%) developed POU. Several predictors of POU were identified. The use of fentanyl (adjusted odds ratio (AOR) = 3.61; 95% confidence interval (CI) 2.63–4.95), slow-release opioids (AOR = 3.02; 95%CI 2.78–3.29), strong opioids (AOR = 2.03; 95%CI 1.55–2.65), Charlson Comorbidity Score ≥ 3 (AOR = 2.09; 95% CI 1.78–2.46), history of substance abuse (AOR = 1.52; 95%CI 1.35–1.72), living in most socioeconomically deprived areas (AOR = 1.40; 95%CI 1.27–1.54), and anti-epileptics (AOR = 2.07; 95%CI 1.89–2.26), non-opioid analgesics (AOR = 2.05; 95%CI 1.89–2.21), antipsychotics (AOR = 1.96; 95%CI 1.78–2.17) or antidepressants (AOR = 1.50; 95%CI 1.41–1.59) medication use were the strongest predictors of POU. Conclusion A significant proportion of patients developed POU, and several factors were associated with POU. The findings will enable healthcare providers and policymakers to target early interventions to prevent POU and related adverse events. [ABSTRACT FROM AUTHOR]

Objective To develop a prognostic model of 1-year mortality for individuals aged 65+ presenting at the emergency department (ED) with a fall based on health care spending patterns to guide clinical decision-making. Design Population-based cohort study (n  = 35,997) included with a fall in 2013 and followed 1 year. Methods Health care spending indicators (dynamical indicators of resilience, DIORs) 2 years before admission were evaluated as potential predictors, along with age, sex and other clinical and sociodemographic covariates. Multivariable logistic regression models were developed and internally validated (10-fold cross-validation). Performance was assessed via discrimination (area under the receiver operating characteristic curve, AUC), Brier scores, calibration and decision curve analysis. Results The AUC of age and sex for mortality was 72.5% [95% confidence interval 71.8 to 73.2]. The best model included age, sex, number of medications and health care spending DIORs. It exhibited high discrimination (AUC: 81.1 [80.5 to 81.6]), good calibration and potential clinical benefit for various threshold probabilities. Overall, health care spending patterns improved predictive accuracy the most while also exhibiting superior performance and clinical benefit. Conclusions Patterns of health care spending have the potential to significantly improve assessments on who is at high risk of dying following admission to the ED with a fall. The proposed methodology can assist in predicting the prognosis of fallers, emphasising the added predictive value of longitudinal health-related information next to clinical and sociodemographic predictors.

Background intrinsic capacity (IC) is a construct encompassing people's physical and mental abilities. There is an implicit link amongst IC domains: cognition, locomotion, nutrition, sensory and psychological. However, little is known about the integration of the domains. Objectives to investigate patterns in the presentation and evolution of IC domain impairments in low-and-middle-income countries and if such patterns were associated with adverse outcomes. Methods secondary analyses of the first two waves of the 10/66 study (population-based surveys conducted in eight urban and four rural catchment areas in Cuba, Dominican Republic, Puerto Rico, Venezuela, Peru, Mexico and China). We applied latent transition analysis on IC to find latent statuses (latent clusters) of IC domain impairments. We evaluated the longitudinal association of the latent statuses with the risk of frailty, disability and mortality, and tested concurrent and predictive validity. Results amongst 14,923 participants included, the four latent statuses were: high IC (43%), low deterioration with impaired locomotion (17%), high deterioration without cognitive impairment (22%), and high deterioration with cognitive impairment (18%). A total of 61% of the participants worsened over time, 35% were stable, and 3% improved to a healthier status. Participants with deteriorated IC had a significantly higher risk of frailty, disability and dementia than people with high IC. There was strong concurrent and predictive validity. (Mortality Hazard Ratio = 4.60, 95%CI 4.16; 5.09; Harrel's C = 0.73 (95%CI 0.72;0.74)). Conclusions half of the study population had high IC at baseline, and most participants followed a worsening trend. Four qualitatively different IC statuses or statuses were characterised by low and high levels of deterioration associated with their risk of disability and frailty. Locomotion and cognition impairments showed other trends than psychological and nutrition domains across the latent statuses. [ABSTRACT FROM AUTHOR]

Background Anticholinergic medicines are associated with adverse outcomes for older people. However, little is known about their use in frailty. The objectives were to (i) investigate the prevalence of anticholinergic prescribing for older patients, and (ii) examine anticholinergic burden according to frailty status. Methods Cross-sectional analysis of Welsh primary care data from the Secure Anonymised Information Linkage databank including patients aged ≥65 at their first GP consultation between 1 January and 31 December 2018. Frailty was identified using the electronic Frailty Index and anticholinergic burden using the Anticholinergic Cognitive Burden (ACB) scale. Descriptive analysis and logistic regression were conducted to (i) describe the type and frequency of anticholinergics prescribed; and (ii) to estimate the association between frailty and cumulative ACB score (ACB-Sum). Results In this study of 529,095 patients, 47.4% of patients receiving any prescription medications were prescribed at least one anticholinergic medicine. Adjusted regression analysis showed that patients with increasing frailty had higher odds of having an ACB-Sum of >3 compared with patients who were fit (mild frailty, adj OR 1.062 (95%CI 1.061–1.064), moderate frailty, adj OR 1.134 (95%CI 1.131–1.136), severe frailty, adj OR 1.208 (95%CI 1.203–1.213)). Conclusions Anticholinergic prescribing was high in this older population. Older people with advancing frailty are exposed to the highest anticholinergic burden despite being the most vulnerable to the associated adverse effects. Older people with advancing frailty should be considered for medicines review to prevent overaccumulation of anticholinergic medications, given the risks of functional and cognitive decline that frailty presents.

Background Vitality is conceptually considered as the underlying capacity influencing other intrinsic capacity (IC) domains and being related to nutrition, physiological reserve and biological ageing. However, there is no consensus on its operationalisation. Objective To investigate the structure and magnitude of the association of vitality with other IC domains and functional difficulties using three operational definitions of vitality. Methods We included 1,389 older adults from the Multidomain Alzheimer Preventive Trial with data on Mini Nutritional Assessment (MNA), handgrip strength and plasma biomarkers (comprising inflammatory and mitochondrial markers). Using path analysis, we examined the effects of vitality on difficulties in basic and instrumental activities of daily living (ADL and IADL) exerted directly and indirectly through the mediation of other IC domains: cognition, locomotion, psychological, vision and hearing. We further explored the longitudinal association of vitality with IC domains, ADL and IADL over 4 years using linear mixed-effect regression. Results We observed significant indirect effects of vitality on IADL, mainly through cognitive, locomotor and psychological domains, regardless of the vitality measurement. Participants with higher vitality had fewer IADL difficulties at follow-up (MNA score: β [95% CI] = −0.020 [−0.037, −0.003]; handgrip strength: −0.011 [−0.023, 0.000]; plasma biomarker-based index: −0.015 [−0.028, −0.002]). Vitality assessed with the plasma biomarker-based index predicted improved locomotion over time. Conclusion Vitality was associated with disability primarily through the mediation of other IC domains. The three indicators examined are acceptable measurements of vitality; biomarkers might be more suitable for the early detection of locomotion decline. [ABSTRACT FROM AUTHOR]

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 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: 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]

Objectives To investigate associations between leisure-time physical activity (LPA) and injurious falls in older women and explore modification of associations by physical function and frailty. Methods Women born during 1946–51 from the Australian Longitudinal Study on Women's Health, injurious falls (self-reported fall with injury and/or medical attention) and self-reported weekly LPA (duration and type). We undertook cross-sectional and prospective analyses using data from 2016 [ n  = 8,171, mean (SD) age 68 (1)] and 2019 surveys (n  = 7,057). Associations were quantified using directed acyclic graph-informed logistic regression and effect modification examined using product terms. Results Participation in LPA as recommended by World Health Organization (150–300 min/week) was associated with lower odds of injurious falls in cross-sectional (adjusted Odds Ratio (OR) 0.74, 95% CI 0.61–0.90) and prospective analyses (OR 0.75, 95% CI 0.60–0.94). Compared with those who reported no LPA, cross-sectionally, odds of injurious falls were lower in those who reported brisk walking (OR 0.77, 95% CI 0.67–0.89) and vigorous LPA (OR 0.86, 95% CI 0.75–1.00). No significant association was found between different types of LPA and injurious falls prospectively. Only cross-sectionally, physical function limitation and frailty modified the association between LPA and injurious falls, with tendencies for more injurious falls with more activity in those with physical limitation or frailty, and fewer injurious falls with more activity among those without physical function limitation or frailty. Conclusion Participation in recommended levels of LPA was associated with lower odds of injurious falls. Caution is required when promoting general physical activity among people with physical limitation or frailty. [ABSTRACT FROM AUTHOR]

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]

Background: Falls in older people are common and morbid. Prediction models can help identifying individuals at higher fall risk. Electronic health records (EHR) offer an opportunity to develop automated prediction tools that may help to identify fall-prone individuals and lower clinical workload. However, existing models primarily utilise structured EHR data and neglect information in unstructured data. Using machine learning and natural language processing (NLP), we aimed to examine the predictive performance provided by unstructured clinical notes, and their incremental performance over structured data to predict falls. Methods: We used primary care EHR data of people aged 65 or over. We developed three logistic regression models using the least absolute shrinkage and selection operator: one using structured clinical variables (Baseline), one with topics extracted from unstructured clinical notes (Topic-based) and one by adding clinical variables to the extracted topics (Combi). Model performance was assessed in terms of discrimination using the area under the receiver operating characteristic curve (AUC), and calibration by calibration plots. We used 10-fold cross-validation to validate the approach. Results: Data of 35,357 individuals were analysed, of which 4,734 experienced falls. Our NLP topic modelling technique discovered 151 topics from the unstructured clinical notes. AUCs and 95% confidence intervals of the Baseline, Topic-based and Combi models were 0.709 (0.700–0.719), 0.685 (0.676–0.694) and 0.718 (0.708–0.727), respectively. All the models showed good calibration. Conclusions: Unstructured clinical notes are an additional viable data source to develop and improve prediction models for falls compared to traditional prediction models, but the clinical relevance remains limited.

Background frailty is a condition of reduced function and health due to ageing processes and is associated with a higher risk of falls, hospitalisation, disability and mortality. Objective to determine the relationship between household wealth and neighbourhood deprivation with frailty status, independently of demographic factors, educational attainment and health behaviours. Design population-based cohort study. Setting communities in England. Subjects in total 17,438 adults aged 50+ from the English Longitudinal Study of Ageing. Methods multilevel mixed-effects ordered logistic regression was used in this study. Frailty was measured using a frailty index. We defined small geographic areas (neighbourhoods) using English Lower layer Super Output Areas. Neighbourhood deprivation was measured by the English Index of Multiple Deprivation, grouped into quintiles. Health behaviours included in this study are smoking and frequency of alcohol consumption. Results the proportion of respondents who were prefrail and frail were 33.8% [95% confidence interval (CI) 33.0–34.6%] and 11.7 (11.1–12.2)%, respectively. Participants in the lowest wealth quintile and living in the most deprived neighbourhood quintile had 1.3 (95% CI = 1.2–1.3) and 2.2 (95% CI = 2.1–2.4) times higher odds of being prefrail and frail, respectively, than the wealthiest participants living in the least deprived neighbourhoods Living in more deprived neighbourhood and poorer wealth was associated with an increased risk of becoming frail. Those inequalities did not change over time. Conclusions in this population-based sample, living in a deprived area or having low wealth was associated with frailty in middle-aged and older adults. This relationship was independent of the effects of individual demographic characteristics and health behaviours. [ABSTRACT FROM AUTHOR]

Background the mySupport advance care planning intervention was originally developed and evaluated in Northern Ireland (UK). Family caregivers of nursing home residents with dementia received an educational booklet and a family care conference with a trained facilitator to discuss their relative's future care. Objectives to investigate whether upscaling the intervention adapted to local context and complemented by a question prompt list impacts family caregivers' uncertainty in decision-making and their satisfaction with care across six countries. Second, to investigate whether mySupport affects residents' hospitalisations and documented advance decisions. Design a pretest–posttest design. Setting in Canada, the Czech Republic, Ireland, Italy, the Netherlands and the UK, two nursing homes participated. Participants in total, 88 family caregivers completed baseline, intervention and follow-up assessments. Methods family caregivers' scores on the Decisional Conflict Scale and Family Perceptions of Care Scale before and after the intervention were compared with linear mixed models. The number of documented advance decisions and residents' hospitalisations was obtained via chart review or reported by nursing home staff and compared between baseline and follow-up with McNemar tests. Results family caregivers reported less decision-making uncertainty (−9.6, 95% confidence interval: −13.3, −6.0, P  < 0.001) and more positive perceptions of care (+11.4, 95% confidence interval: 7.8, 15.0; P  < 0.001) after the intervention. The number of advance decisions to refuse treatment was significantly higher after the intervention (21 vs 16); the number of other advance decisions or hospitalisations was unchanged. Conclusions the mySupport intervention may be impactful in countries beyond the original setting. [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 emergency department (ED) visits have inherent risks for people with dementia yet increase towards the end-of-life. Although some individual-level determinants of ED visits have been identified, little is known about service-level determinants. Objective to examine individual- and service-level factors associated with ED visits by people with dementia in the last year of life. Methods retrospective cohort study using hospital administrative and mortality data at the individual-level, linked to health and social care service data at the area-level across England. The primary outcome was number of ED visits in the last year of life. Subjects were decedents with dementia recorded on the death certificate, with at least one hospital contact in the last 3 years of life. Results of 74,486 decedents (60.5% women; mean age 87.1 years (standard deviation: 7.1)), 82.6% had at least one ED visit in their last year of life. Factors associated with more ED visits included: South Asian ethnicity (incidence rate ratio (IRR) 1.07, 95% confidence interval (CI) 1.02–1.13), chronic respiratory disease as the underlying cause of death (IRR 1.17, 95% CI 1.14–1.20) and urban residence (IRR 1.06, 95% CI 1.04–1.08). Higher socioeconomic position (IRR 0.92, 95% CI 0.90–0.94) and areas with higher numbers of nursing home beds (IRR 0.85, 95% CI 0.78–0.93)—but not residential home beds—were associated with fewer ED visits at the end-of-life. Conclusions the value of nursing home care in supporting people dying with dementia to stay in their preferred place of care must be recognised, and investment in nursing home bed capacity prioritised.

Background There is a need for effective primary care interventions that help older people combat frailty and build resilience. Objective To study the effectiveness of an optimised exercise and dietary protein intervention. Design Multicentre, randomised-controlled, parallel-arm trial. Setting Six primary care practices, Ireland. Methods Six general practitioners enrolled adults aged 65+ with Clinical Frailty Scale score ≤5 from December 2020 to May 2021. Participants were randomised to intervention or usual care with allocation concealed until enrolment. Intervention comprised a 3-month home-based exercise regime, emphasising strength, and dietary protein guidance (1.2 g/kg/day). Effectiveness was measured by comparing frailty levels, based on the SHARE-Frailty Instrument, on an intention-to-treat basis. Secondary outcomes included bone mass, muscle mass and biological age measured by bioelectrical impedance analysis. Ease of intervention and perceived health benefit were measured on Likert scales. Results Of the 359 adults screened, 197 were eligible and 168 enrolled; 156 (92.9%) attended follow-up (mean age 77.1; 67.3% women; 79 intervention, 77 control). At baseline, 17.7% of intervention and 16.9% of control participants were frail by SHARE-FI. At follow-up, 6.3 and 18.2% were frail, respectively. The odds ratio of being frail between intervention and control groups post-intervention was 0.23 (95% confidence interval: 0.07–0.72; P  = 0.011), adjusting for age, gender and site. Absolute risk reduction was 11.9% (CI: 0.8%–22.9%). Number needed to treat was 8.4. Grip strength (P  < 0.001) and bone mass (P  = 0.040) improved significantly. 66.2% found the intervention easy, 69.0% reported feeling better. Conclusion A combination of exercises and dietary protein significantly reduced frailty and improved self-reported health. [ABSTRACT FROM AUTHOR]

Background Previous research has shown older adults experience dynamic changes in frailty status. This study aimed to determine the occurrence of sustained frailty remission and how remission is associated with falls risk. Methods Participants who contributed data to the analysis were in the English Longitudinal Study of Ageing from Waves 1 to 8 (2002–2017). Frailty was defined across waves using the frailty index and categorised into robust, pre-frail and frail. We classified participants who improved their frailty category from Wave 1 (2002) to Wave 2 (2004) and sustained/improved category again into Wave 3 (2006) and compared them with those who were either robust or frail across Waves 1–3. Cox proportional hazard modelling was used to determine the risk of incident falls reported at Waves 4–8, with results expressed as hazard ratios and 95% confidence intervals. Results Of 2,564 participants, 389 (15·2%) improved frailty category and sustained this during Waves 2–3, 1,489 (58·1%) remained robust and 686 (26·8%) remained frail during Waves 1–3. During the 10-year period (Waves 4–8), a total of 549 participants reported a fall. Compared with those who remained frail during Waves 1–3, those who with sustained frailty remission had a lower risk of future falls (HR 0·41; 95% CI = 0·36–0·45). Conclusions Frailty remission is possible and can be sustained across 5 years. There is a lower risk of future falls in those who sustain frailty remission compared with those who remain frail.

Background Virtual wards are being rapidly developed within the National Health Service in the UK, and frailty is one of the first clinical pathways. Virtual wards for older people and existing hospital at home services are closely related. Methods In March 2022, we searched Medline, CINAHL, the Cochrane Database of Systematic Reviews and medRxiv for evidence syntheses which addressed clinical-effectiveness, cost-effectiveness, barriers and facilitators, or staff, patient or carer experience for virtual wards, hospital at home or remote monitoring alternatives to inpatient care. Results We included 28 evidence syntheses mostly relating to hospital at home. There is low to moderate certainty evidence that clinical outcomes including mortality (example pooled RR 0.77, 95% CI 0.60–0.99) were probably equivalent or better for hospital at home. Subsequent residential care admissions are probably reduced (example pooled RR 0.35, 95% CI 0.22–0.57). Cost-effectiveness evidence demonstrated methodological issues which mean the results are uncertain. Evidence is lacking on cost implications for patients and carers. Barriers and facilitators operate at multiple levels (organisational, clinical and patient). Patient satisfaction may be improved by hospital at home relative to inpatient care. Evidence for carer experience is limited. Conclusions There is substantial evidence for the clinical effectiveness of hospital at home but less evidence for virtual wards. Guidance for virtual wards is lacking on key aspects including team characteristics, outcome selection and data protection. We recommend that research and evaluation is integrated into development of virtual ward models. The issue of carer strain is particularly relevant. [ABSTRACT FROM AUTHOR]
