However, declines in physical function do not occur in isolation, and it is recognised that cognitive deconditioning (defined by delayed mental processing as part of a spectrum with fulminant delirium at one end) is commonly encountered by patients in hospital. Whilst the term 'deconditioning' is descriptive, it perhaps leads to under-emphasis on the inherent organ dysfunction that is associated, and also implies some ease of reversibility.

{"title":"Reimagining and rebranding advance care planning","authors":"Chetna Malhotra","doi":"10.1093/ageing/afae233","DOIUrl":"https://doi.org/10.1093/ageing/afae233","url":null,"abstract":"Advance care planning (ACP) has traditionally aimed at ensuring that patients’ end-of-life (EOL) wishes are understood and respected. However, recent literature raises concerns about its effectiveness, with many trials indicating that ACP does not significantly improve goal-concordant care, enhance quality of life or reduce healthcare costs. This is because patients’ future decisions are influenced by their transient preferences due to projection bias. To remain relevant, ACP requires a radical shift in perspective, implementation and branding. First, ACP’s mission must be redefined with a focus on: Educate, Share and Prepare. This perspective emphasises ongoing conversations about patient health and illness, sharing of patients’ current values and goals of care and preparation for the future, rather than making definitive future decisions. Second, ACP should be integrated into routine care, normalising these discussions. Simplifying ACP processes and shifting incentives to support shared responsibility among stakeholders can enhance integration. Last, rebranding ACP as ‘Advance Care Preparation’ can clarify its purpose, distinguishing it from EOL planning and increasing its uptake. This rebranding ensures that ACP meets the evolving needs of patients and their families, ultimately enhancing the quality of care and patient satisfaction. These changes in perspective, implementation and branding can transform ACP into a valuable tool for delivering compassionate, patient-centred healthcare, making it relevant to all individuals.","PeriodicalId":7682,"journal":{"name":"Age and ageing","volume":null,"pages":null},"PeriodicalIF":6.7,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142489743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fewer opportunities to take part in research, as well as assumptions made by others about their interest or wishes, creates challenges for residents’ inclusion in research. Early discussions about research preferences and wishes may be beneficial. This qualitative study aimed to explore stakeholders’ views about how care home residents can be supported to communicate their wishes about research participation. Method Semi-structured interviews were conducted with 25 stakeholders: care home residents (n = 5), relatives (n = 5), care home staff (n = 5), other health and social care professionals who work with care homes (n = 6), and care home researchers (n = 4). Interviews were conducted virtually or face-to-face and data were analysed using thematic analysis. Results Views about resident research participation, the barriers and facilitators to their inclusion, and the role of advance research planning were iteratively organized into three themes: (i) We’re of no value to research; (ii) Research is difficult; and (iii) Advance research planning: good in theory, challenging in practice. Subthemes were also identified, and findings were discussed with a Patient and Public Involvement group for additional reflections. Conclusions Stakeholders identified a number of barriers to including care home residents in research, including knowing their preferences about research. The development of interventions to facilitate communication that can be adapted to individuals’ requirements are needed to support discussions and decision-making with care home residents about wishes and preferences for future research participation.","PeriodicalId":7682,"journal":{"name":"Age and ageing","volume":null,"pages":null},"PeriodicalIF":6.7,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142489744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated different operationalizations of the WFG algorithm and compared its predictive performance to other screening tools for falls, namely: the American Geriatrics Society and British Geriatrics Society (AGS/BGS) algorithm, the 3KQ on their own and fall history on its own. Methods We included data from 1509 adults aged ≥65 years from the population-based Longitudinal Aging Study Amsterdam. The outcome was ≥1 fall during 1-year follow-up, which was ascertained using fall calendars. The screening tools’ items were retrospectively operationalized using baseline measures, using proxies where necessary. Results Sensitivity ranged between 30.9–48.0% and specificity ranged between 77.0–88.2%. Operationalizing the algorithm with the 3KQ instead of fall history yielded a higher sensitivity but lower specificity, whereas operationalization with the Clinical Frailty Scale (CFS) classification tree instead of Fried’s frailty criteria did not affect predictive performance. Compared to the WFG algorithm, the AGS/BGS algorithm and fall history on its own yielded similar predictive performance, whereas the 3KQ on their own yielded a higher sensitivity but lower specificity. Conclusion The WFG algorithm can identify patients at risk of a fall, especially when the 3KQ are included in its operationalization. The CFS and Fried’s frailty criteria may be used interchangeably in the algorithm’s operationalization. The algorithm performed similarly compared to other screening tools, except for the 3KQ on their own, which have higher sensitivity but lower specificity and lack clinical recommendations per risk category.","PeriodicalId":7682,"journal":{"name":"Age and ageing","volume":null,"pages":null},"PeriodicalIF":6.7,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142449495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet access barriers and ageist practices still prevail within many rehabilitation services. This commentary reflects on a report and recommendations published by the British Geriatrics Society in May 2024. As lead author for the report, I share my personal reflection on the key messages and take this opportunity to thank the multidisciplinary contributors. Reablement, Rehabilitation, Recovery: everyone’s business describes why rehabilitation matters to older people and their caregivers. It provides evidence and examples of practice at different care touchpoints and makes the case that rehabilitation is everyone’s business and knows no boundaries, whether by condition, profession, care setting or taxonomy. The report sets out 12 key actions for health and care systems to deliver effective and integrated rehabilitation as a right for all older people, wherever and whenever they need it. To realise that right, health and care professionals must work together, and with their local community partners, to build capacity and capability for reablement, rehabilitation and recovery across the whole workforce. With population ageing and many more people living with frailty or multimorbidity, there is an urgent need for greater investment in rehabilitation to prevent, delay or reduce disability, caregiver burden and demand for long-term care. This timely BGS report should be essential reading for all who plan, commission, provide or assure health and care services for older people.","PeriodicalId":7682,"journal":{"name":"Age and ageing","volume":null,"pages":null},"PeriodicalIF":6.7,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods Sixty-eight older adults (66–79 years, 56% women), not engaged in regular exercise, were randomised to 3 months of twice-weekly supramaximal HIT (20 minutes including 10 × 6-second intervals) or MIT (40 minutes including 3 × 8-minute intervals). Both groups performed the training on stationary bicycles in a group setting. Target intensity was watt-controlled, with standardised cadence and individualised resistance. Outcomes analysed with linear-mixed models included leg power (Nottingham Power Rig), hand grip strength (Jamar dynamometer), static and dynamic balance (One leg stance, 30-second step test), chair stand (30-second chair stand), and anaerobic cycling performance (modified Borg Cycle Strength Test). Results Baseline values were (supramaximal HIT/MIT, mean ± SD) leg power 198 ± 60/189 ± 53 W, hand grip strength 4.2 ± 1.0/4.3 ± 1.1 N/kg, static balance 64 ± 41/62 ± 41 s, dynamic balance 39 ± 7/38 ± 5 steps, chair stands 22 ± 6/22 ± 6 and anaerobic cycling performance 224 ± 60/217 ± 55 W. At 3-month follow-up, a between-group difference in favour of supramaximal HIT [95% CI] was observed in anaerobic cycling performance of 19[3;35] W. Within-group mean changes for supramaximal HIT/MIT were for leg power 8.4[0.9;15.8]/6.0[−1.3;13.3] W, hand grip strength 0.14[0.00;0.27]/0.13[−0.01;0.26] N/kg, static balance 11[3;20]/10[1;18] s, dynamic balance 1.6[0.3;2.8]/2.3[1.1;3.6] steps, 2.1[1.1;3.1]/1.4[0.4;2.3] chair stands and anaerobic cycling performance 31.3[19.6;43.0]/12.0[0.4;23.5] W.

We assessed the predictive ability of the HFRS regarding care consumption outcomes, frailty domain impairments and mortality among older adults with cancer, using the Geriatric 8 (G8) screening tool as a clinical benchmark. Methods This retrospective, linkage-based study included patients aged ≥70 years with solid tumor, enrolled in the Elderly Cancer Patients (ELCAPA) multicentre cohort study (2016–2020) and hospitalized in acute care within the Greater Paris University Hospitals. HFRS scores, which encompass hospital-acquired problems and frailty-related syndromes, were calculated using data from the index admission and the preceding 6 months. A multidomain geriatric assessment (GA), including cognition, nutrition, mood, functional status, mobility, comorbidities, polypharmacy, incontinence, and social environment, was conducted at ELCAPA inclusion, with computation of the G8 score.

Methods We analysed T1 brain MRI data of 771 old adults (69.8 ± 5.2 years) from the Whitehall II MRI substudy, with MRI data collected between 2012 and 2016. Social mobility was defined by SEP changes from their fathers’ generation to mid-life status. Brain structural outcomes include grey matter (GM) volume and cortical thickness (CT) covering whole brain. Global cognition was measured by the Mini Mental State Examination. We firstly conducted analysis of covariance to identify regional difference of GM volume and cortical thickness across stable high/low and upward/downward mobility groups, followed with diagonal reference models studying the relationship between mobility and brain cognitive outcomes, apart from SEP origin and destination. We additionally conducted linear mixed models to check mobility interaction over time, where global cognition was derived from three phases across 2002 to 2017. Results Social mobility related to 48 out of the 136 GM volume regions and 4 out of the 68 CT regions. Declined volume was particularly seen in response to downward mobility, whereas no independent association of mobility with global cognition was observed.

Frailty is a state of vulnerability to stressors, which is often characterised by impairment in the physical, psychological and/or social domain. Objective This study aims to examine the bidirectional association between loneliness and frailty across the different domains. Methods The study included 1735 older adults from the Urban Health Centres Europe project. Loneliness was assessed using the six-item De Jong Gierveld Loneliness Scale. Frailty was assessed by the Tilburg Frailty Indicator. Multivariate linear regression and cross-lagged panel models were used to explore the associations between the social and emotional loneliness dimensions and overall, physical, psychological and social frailty. Results A bidirectional association existed between overall loneliness and overall frailty (loneliness to frailty: β = 0.09, 95% CI: 0.03, 0.15; frailty to loneliness: β = 0.05, 95% CI: 0.004, 0.10). Higher levels of overall loneliness at baseline were associated with higher levels of psychological frailty at follow-up (β = 0.05, 95% CI: 0.00, 0.10). The reverse association was not significant.
