Age and ageing最新文献

Background: The aim of this study was to develop and validate a functional ability index (FAI) that incorporates aspects of intrinsic capacity and environmental factors of older individuals based on the World Health Organization framework of healthy ageing.

Methods: Data of 7016 participants ≥60 years participating in the baseline survey of China Health and Retirement Longitudinal Study was used for the development and internal validation of the FAI. External validation was performed in a separate cohort of 1295 older individuals aged ≥60 years. Functional independency was considered the primary outcome and additional proxies of healthy ageing were considered as secondary outcomes. Cluster dendrogram was used to identify the distinct hierarchical clusters of all included variables for inclusion in the FAI. Backward elimination logistic regression model was implemented to identify the most significant variables associated with independency to be included in the FAI.

Results: The FAI score ranged from 0 to 19 and individuals having FAI ≥ 12 were more likely to be independent and at lower risk of negative outcomes. For each unit increase in the FAI the risk of having independency increased by 30%-58% cross-sectionally in the two cohorts, whilst the 2-year risk of independency increased by 20%. The FAI demonstrated a C-statistic of 0.73 (95% confidence interval, 0.72 and 0.75) for the primary outcome.

Conclusions: The FAI we developed effectively measured the functional ability status of community dwelling older individuals. FAI could serve as a tool for evaluating older individual's functional ability in routine health assessment.

The 30th Olympiad took place in July 2024. At first glance, sports science and training of elite athletes may appear to be of little relevance to geriatric medicine. However, there are important parallels between the practice of geriatric medicine and elite sports and lessons that we can learn from our sports science colleagues. Elite athletes and older people are operating at the margins of physiological capacity. Both benefit from tailored, scientifically informed training programmes delivered and monitored by a multidisciplinary team. There are parallels between the comprehensive geriatric assessment and the philosophy of marginal gains pioneered by British Cycling. Insights into the biology of skeletal muscle function are beginning to translate into the development of clinical interventions and substances that offer an unfair advantage in sport by improving muscle strength and physical performance may be of therapeutic benefit in sarcopenia. The 2024 Olympics provide an opportunity for us to learn lessons for excellence in our research and provide an opportunity to promote exercise across the life course-important for healthy ageing.

Background: Postoperative delirium (POD) significantly impacts older surgical patients, necessitating effective prevention strategies.

Objective: To assess the effectiveness of the Pre-Interventional Preventive Risk Assessment (PIPRA) automated delirium risk prediction tool alongside non-pharmacological prevention strategies on POD incidence, hospital length of stay (LOS) and nursing time.

Methods: This quality improvement project, set in a 335-bed Swiss private hospital, employed a before-after design to evaluate the impact of PIPRA and preventive measures on POD, LOS and nursing time in non-cardiac and non-intracranial surgery inpatients aged 60 or older. The control phase focused on enhancing POD screening, whilst the intervention phase incorporated PIPRA for risk assessment and staff training to enable targeted non-pharmacological prevention in patients at risk.

Results: A total of 866 patients were included; 299 control and 567 intervention. The odds ratio of POD, comparing the intervention group to the control, was 0.71 [95% confidence interval (CI) 0.44-1.16] when adjusting for baseline patient characteristics. The intervention was associated with an LOS 0.94 (95% CI 0.85-1.05) and nursing time 0.96 (95% CI 0.86-1.07) times that of the control, adjusted for baseline patient characteristics. Medium risk patients (21.6% of patients) had an LOS 0.74 (95% CI 0.59-0.92) and required nursing time 0.79 (95% CI from 0.62-1.00) times the control, adjusted for baseline patient characteristics, equivalent to an LOS reduction of 1.36 days and nursing time saving of 19.3 hours per patient.

Conclusions: Medium risk patients in the intervention group had shorter LOS and nursing time compared to the control group, underscoring the importance of targeted prevention.

Background: Falls have high socioeconomic costs. Information and communication technologies may support provision and monitoring of multisensory (MSR) physiotherapy programmes. The HOLOBalance platform used augmented reality holograms to provide patient-centred, individualised MSR.

Objectives: To determine the platform's safety, acceptability and feasibility, investigate functional gait and dynamic balance benefits and provide data for a definitive trial.

Design and setting: Single-blinded pilot randomised controlled feasibility study. Interventions were conducted at clinical sites or participants' homes in three European countries.

Participants: Community-dwelling older adults (median age 73 years; 64.2% female) at risk of falls were enrolled (May 2020-August 2021).

Methods: Participants were randomised to an 8-week clinic or home-based telerehabilitation MSR or OTAGO (control group) programme. Compliance, satisfaction, and adverse events determined feasibility. Clinical outcomes, assessed (blinded) within one-week prior to and post-intervention, included functional gait assessment (FGA), Mini BESTest and cognitive function.

Results: Randomisation to completion rate was 76.15% with 109 participants recruited (n = 289 screened). Drop-out rate was similar between groups. Adverse events were reported (n = 3) in the control group. Sixty-nine percent would recommend the HOLOBalance intervention. Findings were similar for the home and clinic-based arms of each intervention; data was combined for analysis. FGA (95%CI [1.63, 4.19]) and Mini-BESTest (95%CI [1.46, 3.93]) showed greater improvement in the HOLOBalance group with a clinically meaningful change of 4/30 noted for the FGA.

Conclusions: HOLObalance was feasible to implement and acceptable to older adults at risk of falls, with FGA and Mini-BEST improvements exceeding those for the OTAGO programme. A definitive trial is warranted.

Background: Cognitive decline, a common process of brain ageing, has been associated with telomere length (TL). Delving into the identification of reliable biomarkers of brain ageing is essential to prevent accelerated cognitive impairment.

Methods: We selected 317 non-smoking 'Prevención con Dieta Mediterránea-Plus' (PREDIMED-Plus) participants (mean age, 65.8 ± 5.0 years) with metabolic syndrome from two trial centres who were following a lifestyle intervention. We measured TL and cognitive function at baseline and after 3 and 4 years of follow-up, respectively. Associations between baseline or 3-year changes in TL and baseline or 4-year changes in cognitive function were analysed using multivariable regression models.

Results: Baseline TL was not associated with baseline cognitive performance. Nevertheless, longer baseline TL was associated with improved 4-year changes in the Executive Function domain (β: 0.29; 95%CI: 0.12 to 0.44; P < 0.001) and the Global Cognitive Function domain (β: 0.19; 95%CI: 0.05 to 0.34; P = 0.010). Besides, a positive association was found between longer baseline TL and improved 4-year changes in the animal version of the Verbal Fluency Test (β: 0.33; 95%CI: 0.12 to 0.52; P = 0.002). By contrast, 3-year changes in TL were not associated with changes in cognitive function after 4 years.

Conclusions: Longer baseline TL could protect from cognitive decline and be used as a useful biomarker of brain ageing function in an older Mediterranean population at risk of cardiovascular disease and cognitive impairment.

Background: Evidence concerning tolerability of sodium-glucose co-transporter-2 (SGLT2) inhibitors in older adults is limited due to under-representation in clinical trials. Our study aimed to determine the extent to which SGLT2 inhibitor intolerance increases with age and explore additional factors associated with intolerance.

Methods: This retrospective observational study included patients in the Veterans Health Administration who initiated an SGLT2 inhibitor between 1 January 2013 and 31 December 2021. One-year discontinuation served as a proxy for intolerance. Relative risk (RR) for 1-year discontinuation was contrasted across age groups using log-binomial regression to adjust for confounding.

Results: Of 232 495 patients who initiated an SGLT2 inhibitor, 60 582 (26.1%) discontinued within one year. A difference was observed across age groups, <65, 65-74, 75-84 and ≥85 years, where 25.8%, 25.3%, 28.5% and 34.9% of patients discontinued, respectively (P < .001). After adjustment for confounding factors, patients 75-84 and ≥85 years were at 8% (RR = 1.08; 95% CI: 1.05, 1.10) and 21% increased risk (RR = 1.21; 95% CI: 1.15, 1.26) for discontinuation, respectively, relative to patients <65 years. Additional risk factors were identified: female (RR = 1.41; 95% CI: 1.37, 1.45), estimated glomerular filtration rate stage 4 (RR = 1.49; 95% CI: 1.39, 1.60), underweight (RR = 1.15; 95% CI: 1.03, 1.29), urinary tract infection history (RR = 1.25; 95% CI: 1.21, 1.30) and yeast infection history (RR = 1.39; 95% CI: 1.27, 1.51).

Conclusion: No clinically meaningful differences in SGLT2 inhibitor intolerance were observed in patients up to 84 years. Our findings support having closer follow-up when initiating in patients 85 years and older.

Background: Falls in hospital remain a common and costly patient safety issue internationally. There is evidence that falls in hospitals can be prevented by multifactorial programs and by education for patients and staff, but these are often not routinely or effectively implemented in practice. Perspectives of multiple key stakeholder groups could inform implementation of fall prevention strategies.

Methods: Clinicians of different disciplines, patients and their families were recruited from wards at two acute public hospitals. Semi-structured interviews and focus groups were conducted to gain a broad understanding of participants' perspectives about implementing fall prevention programs. Data were analysed using an inductive thematic approach.

Results: Data from 50 participants revealed three key themes across the stakeholder groups shaping implementation of acute hospital fall prevention programs: (i) 'Fall prevention is a priority, but whose?' where participants agreed falls in hospital should be addressed but did not necessarily see themselves as responsible for this; (ii) 'Disempowered stakeholders' where participants expressed feeling frustrated and powerless with fall prevention in acute hospital settings; and (iii) 'Shared responsibility may be a solution' where participants were optimistic about the positive impact of collective action on effectively implementing fall prevention strategies.

Conclusion: Key stakeholder groups agree that hospital fall prevention is a priority, however, challenges related to role perception, competing priorities, workforce pressure and disempowerment mean fall prevention may often be neglected in practice. Improving shared responsibility for fall prevention implementation across disciplines, organisational levels and patients, family and staff may help overcome this.

Background: End-of-life periods are often characterised by suboptimal healthcare use (HCU) patterns in persons aged 65 years and older, with negative effects on health and quality of life. Understanding care trajectories (CTs) and transitions in this period can highlight potential areas of improvement, a subject yet only little studied.

Objective: To propose a typology of CTs, including care transitions, for older individuals in the 2 years preceding death.

Design: Retrospective cohort study.

Methods: We used multidimensional state sequence analysis and data from the Care Trajectories-Enriched Data (TorSaDE) cohort, a linkage between a Canadian health survey and Quebec health administrative data.

Results: In total, 2080 decedents were categorised into five CT groups. Group 1 demonstrated low HCU until the last few months, whilst group 2 showed low HCU over the first year, followed by a steady increase. A gradual increase over the 2 years was observed for groups 3 and 4, though more pronounced towards the end for group 3. A persistent high HCU was observed for group 5. Groups 2 and 4 had higher proportions of cancer diagnoses and palliative care, as opposed to comorbidities and dementia for groups 3 and 5. Overall, 68.4% of individuals died in a hospital, whilst 27% received palliative care there. Care transitions increased rapidly towards the end, most notably in the last 2 weeks.

Conclusion: This study provides an understanding of the variability of CTs in the last two years of life, including place of death, a critical step towards quality improvement.

Background: Continuity of care is essential to older patients' health outcomes, especially for those with complex needs. It is a key function of primary healthcare. Despite China's policy efforts to promote continuity of care and an integrated healthcare system, primary healthcare centres (PHCs) are generally very underused.

Objectives: To explore the experience and perception of continuity of care in older cancer patients, and to examine how PHCs play a role in the continuity of care within the healthcare system in China.

Methods: A qualitative study using semi-structured interviews was conducted in two tertiary hospitals in Nantong city, Jiangsu province, China. A combination of deductive and inductive analysis was conducted thematically.

Results: Interviews with 29 patients highlighted three key themes: no guidance for patients in connecting with different levels of doctors, unmet patients' needs under specialist-led follow-up care, and poor coordination and communication across healthcare levels. This study clearly illustrated patients' lack of personal awareness and experience of care continuity, a key issue despite China's drive for an integrated healthcare system.

Conclusion: The need for continuity of care at each stage of cancer care is largely unmeasured in the current healthcare system for older patients. PHCs offer benefits which include convenience, less burdened doctors with more time, and lower out-of-pocket payment compared to tertiary hospitals, especially for patients with long-term healthcare needs. However, addressing barriers such as the absence of integrated medical records and unclear roles of PHCs are needed to improve the crucial role of PHCs in continuity of care.
