The effectiveness of a comprehensive geriatric assessment intervention program for frailty in community-dwelling older people: a randomized, controlled trial

Effectiveness of Community-Based Rehabilitation (CBR) Centers for Improving Physical Fitness for Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis

To synthesise the best available evidence for the effectiveness of interventions delivered in community-based rehabilitation (CBR) centers on physical fitness, for community-dwelling older adults living in Asian countries. This study is a systematic review and meta-analysis. Seven English and two Chinese electronic databases were searched for randomised controlled trials (RCTs) and quasi-experimental studies that were conducted by centers providing CBR. Independent reviewers screened, quality-appraised and extracted data. The primary outcome was physical fitness measured by validated assessment tools, including the Timed Up and Go Test (TUG), gait speed, hand grip strength, Functional Reach Test (FRT), and one-leg standing test. Assessments of activity of daily living and quality of life using tools including the Barthel Index, Short Form (SF)-12, and SF-36 were secondary outcomes. After screening 5,272 studies, 29 studies were included (16 RCTs, 13 quasi-experimental studies) from four countries. Meta-analyses found that CBR programs significantly decreased TUG time (mean difference [MD], -1.89 seconds; 95% confidence interval [95% CI], -2.84 to -0.94; I2=0%; Z=3.90, p<0.0001), improved gait speed (MD, 0.10 m/s; 95% CI, 0.01-0.18; I2=0%; Z=2.26, p=0.02), and increased one-leg standing time (MD, 2.81 seconds; 95% CI, 0.41-5.22; I2=0%; Z=2.29, p=0.02). Handgrip strength and FRT showed no statistically significant improvement in the meta-analyses. CBR may improve aspects of physical fitness for older adults in Asian countries. However, variability in intervention components and measurement tools reduced the ability to pool individual studies. Further trials are required with robust designs including standardised measures of physical fitness.

Reversing frailty in older adults: a scoping review

BACKGROUND

Individuals 65 years or older are presumably more susceptible to becoming frail, which increases their risk of multiple adverse health outcomes. Reversing frailty has received recent attention; however, little is understood about what it means and how to achieve it. Thus, the purpose of this scoping review is to synthesize the evidence regarding the impact of frail-related interventions on older adults living with frailty, identify what interventions resulted in frailty reversal and clarify the concept of reverse frailty.

METHODS

We followed Arksey and O'Malley's five-stage scoping review approach and conducted searches in CINAHL, EMBASE, PubMed, and Web of Science. We hand-searched the reference list of included studies and conducted a grey literature search. Two independent reviewers completed the title, abstract screenings, and full-text review using the eligibility criteria, and independently extracted approximately 10% of the studies. We critically appraised studies using Joanna Briggs critical appraisal checklist/tool, and we used a descriptive and narrative method to synthesize and analyze data.

RESULTS

Of 7499 articles, thirty met the criteria and three studies were identified in the references of included studies. Seventeen studies (56.7%) framed frailty as a reversible condition, with 11 studies (36.7%) selecting it as their primary outcome. Reversing frailty varied from either frail to pre-frail, frail to non-frail, and severe to mild frailty. We identified different types of single and multi-component interventions each targeting various domains of frailty. The physical domain was most frequently targeted (n = 32, 97%). Interventions also varied in their frequencies of delivery, intensities, and durations, and targeted participants from different settings, most commonly from community dwellings (n = 23; 69.7%).

CONCLUSION

Some studies indicated that it is possible to reverse frailty. However, this depended on how the researchers assessed or measured frailty. The current understanding of reverse frailty is a shift from a frail or severely frail state to at least a pre-frail or mildly frail state. To gain further insight into reversing frailty, we recommend a concept analysis. Furthermore, we recommend more primary studies considering the participant's lived experiences to guide intervention delivery.

Frailty as a Predictor of Outcomes in Subarachnoid Hemorrhage: A Systematic Review and Meta-Analysis

Frailty is an emerging concept in clinical practice used to predict outcomes and dictate treatment algorithms. Frail patients, especially older adults, are at higher risk for adverse outcomes. Aneurysmal subarachnoid hemorrhage (aSAH) is a neurosurgical emergency associated with high morbidity and mortality rates that have previously been shown to correlate with frailty. However, the relationship between treatment selection and post-treatment outcomes in frail aSAH patients is not established. We conducted a meta-analysis of the relevant literature in accordance with PRISMA guidelines. We searched PubMed, Embase, Web of Science, and Google Scholar using "Subarachnoid hemorrhage AND frailty" and "subarachnoid hemorrhage AND frail" as search terms. Data on cohort age, frailty measurements, clinical grading systems, and post-treatment outcomes were extracted. Of 74 studies identified, four studies were included, with a total of 64,668 patients. Percent frailty was 30.4% under a random-effects model in all aSAH patients (p < 0.001). Overall mortality rate of aSAH patients was 11.7% when using a random-effects model (p < 0.001). There was no significant difference in mortality rate between frail and non-frail aSAH patients, but this analysis only included two studies and should be interpreted cautiously. Age and clinical grading, rather than frailty, independently predicted outcomes and mortality in aSAH patients.

Case management for integrated care of older people with frailty in community settings

BACKGROUND

Ageing populations globally have contributed to increasing numbers of people living with frailty, which has significant implications for use of health and care services and costs. The British Geriatrics Society defines frailty as "a distinctive health state related to the ageing process in which multiple body systems gradually lose their inbuilt reserves". This leads to an increased susceptibility to adverse outcomes, such as reduced physical function, poorer quality of life, hospital admissions, and mortality. Case management interventions delivered in community settings are led by a health or social care professional, supported by a multidisciplinary team, and focus on the planning, provision, and co-ordination of care to meet the needs of the individual. Case management is one model of integrated care that has gained traction with policymakers to improve outcomes for populations at high risk of decline in health and well-being. These populations include older people living with frailty, who commonly have complex healthcare and social care needs but can experience poorly co-ordinated care due to fragmented care systems.

OBJECTIVES

To assess the effects of case management for integrated care of older people living with frailty compared with usual care.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, Health Systems Evidence, and PDQ Evidence and databases from inception to 23 September 2022. We also searched clinical registries and relevant grey literature databases, checked references of included trials and relevant systematic reviews, conducted citation searching of included trials, and contacted topic experts.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared case management with standard care in community-dwelling people aged 65 years and older living with frailty.

DATA COLLECTION AND ANALYSIS

We followed standard methodological procedures recommended by Cochrane and the Effective Practice and Organisation of Care Group. We used the GRADE approach to assess the certainty of the evidence.

MAIN RESULTS

We included 20 trials (11,860 participants), all of which took place in high-income countries. Case management interventions in the included trials varied in terms of organisation, delivery, setting, and care providers involved. Most trials included a variety of healthcare and social care professionals, including nurse practitioners, allied healthcare professionals, social workers, geriatricians, physicians, psychologists, and clinical pharmacists. In nine trials, the case management intervention was delivered by nurses only. Follow-up ranged from three to 36 months. We judged most trials at unclear risk of selection and performance bias; this consideration, together with indirectness, justified downgrading the certainty of the evidence to low or moderate. Case management compared to standard care may result in little or no difference in the following outcomes. • Mortality at 12 months' follow-up (7.0% in the intervention group versus 7.5% in the control group; risk ratio (RR) 0.98, 95% confidence interval (CI) 0.84 to 1.15; I2 = 11%; 14 trials, 9924 participants; low-certainty evidence) • Change in place of residence to a nursing home at 12 months' follow-up (9.9% in the intervention group versus 13.4% in the control group; RR 0.73, 95% CI 0.53 to 1.01; I2 = 0%; 4 trials, 1108 participants; low-certainty evidence) • Quality of life at three to 24 months' follow-up (results not pooled; mean differences (MDs) ranged from -6.32 points (95% CI -11.04 to -1.59) to 6.1 points (95% CI -3.92 to 16.12) when reported; 11 trials, 9284 participants; low-certainty evidence) • Serious adverse effects at 12 to 24 months' follow-up (results not pooled; 2 trials, 592 participants; low-certainty evidence) • Change in physical function at three to 24 months' follow-up (results not pooled; MDs ranged from -0.12 points (95% CI -0.93 to 0.68) to 3.4 points (95% CI -2.35 to 9.15) when reported; 16 trials, 10,652 participants; low-certainty evidence) Case management compared to standard care probably results in little or no difference in the following outcomes. • Healthcare utilisation in terms of hospital admission at 12 months' follow-up (32.7% in the intervention group versus 36.0% in the control group; RR 0.91, 95% CI 0.79 to 1.05; I2 = 43%; 6 trials, 2424 participants; moderate-certainty evidence) • Change in costs at six to 36 months' follow-up (results not pooled; 14 trials, 8486 participants; moderate-certainty evidence), which usually included healthcare service costs, intervention costs, and other costs such as informal care.

AUTHORS' CONCLUSIONS

We found uncertain evidence regarding whether case management for integrated care of older people with frailty in community settings, compared to standard care, improved patient and service outcomes or reduced costs. There is a need for further research to develop a clear taxonomy of intervention components, to determine the active ingredients that work in case management interventions, and identify how such interventions benefit some people and not others.

Circulating inflammatory biomarker responses in intervention trials in frail and sarcopenic older adults: A systematic review and meta-analysis

Consistent with the inflammaging concept, cross-sectional associations have been established between inflammatory biomarkers, frailty and sarcopenia. Less certain is the value of inflammatory markers in monitoring potential anti-inflammatory effects of therapeutic interventions targeted at frailty and sarcopenia. The aims of this systematic review and meta-analysis are to determine if there is a measurable change in inflammatory or immune biomarkers in interventions that improve frailty or sarcopenia and 2. To determine if there are specific inflammatory biomarkers with greater sensitivity to change. In total, 3051 articles were scanned with 16, primarily exercise and nutrition interventions, included in the systematic review and 11 in the meta-analysis. At least one of C reactive protein (CRP), interleukin-6 (IL-6) or tumour necrosis factor alpha (TNF-α) was reduced in 10 of the 16 review studies but only 3/13 studies reported reductions in multiple markers. CRP, IL-6 and TNF-α were individually sensitive to change in 5/11, 3/12 and 5/12 studies respectively. In meta-analyses, there was a positive effect favouring intervention conditions for CRP (SMD = -0.28, p = 0.05) and IL-6 (SMD = -0.28, p = 0.05) but not TNF- α (SMD = -0.12, p = 0.48). There were specific issues with the quality of these studies which were not designed with an inflammatory marker as the primary outcome. In conclusion, interventions that improve frailty and sarcopenia can also reduce CRP, IL-6 and TNF-α but the literature lacks consistency. We are unable to conclude any one marker as being superior to others.

Prediction of 30-Day Readmission in Hospitalized Older Adults Using Comprehensive Geriatric Assessment and LACE Index and HOSPITAL Score

(1) Background: Elders have higher rates of rehospitalization, especially those with functional decline. We aimed to investigate potential predictors of 30-day readmission risk by comprehensive geriatric assessment (CGA) in hospitalized patients aged 65 years or older and to examine the predictive ability of the LACE index and HOSPITAL score in older patients with a combination of malnutrition and physical dysfunction. (2) Methods: We included patients admitted to a geriatric ward in a tertiary hospital from July 2012 to August 2018. CGA components including cognitive, functional, nutritional, and social parameters were assessed at admission and recorded, as well as clinical information. The association factors with 30-day hospital readmission were analyzed by multivariate logistic regression analysis. The predictive ability of the LACE and HOSPITAL score was assessed using receiver operator characteristic curve analysis. (3) Results: During the study period, 1509 patients admitted to a ward were recorded. Of these patients, 233 (15.4%) were readmitted within 30 days. Those who were readmitted presented with higher comorbidity numbers and poorer performance of CGA, including gait ability, activities of daily living (ADL), and nutritional status. Multivariate regression analysis showed that male gender and moderately impaired gait ability were independently correlated with 30-day hospital readmissions, while other components such as functional impairment (as ADL) and nutritional status were not associated with 30-day rehospitalization. The receiver operating characteristics for the LACE index and HOSPITAL score showed that both predicting scores performed poorly at predicting 30-day hospital readmission (C-statistic = 0.59) and did not perform better in any of the subgroups. (4) Conclusions: Our study showed that only some components of CGA, mobile disability, and gender were independently associated with increased risk of readmission. However, the LACE index and HOSPITAL score had a poor discriminating ability for predicting 30-day hospitalization in all and subgroup patients. Further identifiers are required to better estimate the 30-day readmission rates in this patient population.

The measurements of frailty and their possible application to spinal conditions: a systematic review

BACKGROUND CONTEXT

Frailty is associated with an increased risk of postoperative adverse events (AEs) within the surgical spine population. Multiple frailty tools have been reported in the surgical spine literature. However, the applicability of these tools remains unclear.

PURPOSE

Primary objective is to appraise the construct, feasibility, objectivity, and clinimetric properties of frailty tools reported in the surgical spine literature. Secondary objectives included determining the applicability and the most sensitive surgical spine population for each tool.

STUDY DESIGN

Systematic Review.

PATIENT SAMPLE

Studies reporting the use of a clinical frailty tool with a defined methodology in the adult surgical population (age ≥18 years).

OUTCOME MEASURES

Postoperative adverse events (AEs) including mortality, major and minor morbidity, length of stay (LOS), unplanned readmission and reoperation, admission to the Intensive Care Unit (ICU), and adverse discharge disposition; postoperative patient-reported outcomes (health-related quality of life (HRQoL), functional, cognitive, and symptomatic); radiographic outcomes; and postoperative frailty trajectory.

METHODS

This systematic review was registered with PROSPERO: CRD42019109045. Publications from January 1950 to December 2020 were identified by a comprehensive search of PubMed, Ovid, and Embase, supplemented by manual screening. Studies reporting and validating a frailty tool in the surgical spine population with a measurable outcome were included. Each tool and its clinimetric properties were evaluated using validated criteria and definitions. The applicability of each tool and its most sensitive surgical spine population was determined by panel consensus. Bias was assessed using the Newcastle-Ottawa Scale.

RESULTS

47 studies were included in the final qualitative analysis. A total of 14 separate frailty tools were identified, in which 9 tools assessed frailty according to the cumulative deficit definition, while 4 instruments utilized phenotypic or weighted frailty models. One instrument assessed frailty according to the comprehensive geriatric assessment (CGA) model. Twelve measures were validated as risk stratification tools for predicting postoperative AEs, while 1 tool investigated the effect of spine surgery on postoperative frailty trajectory. The modified frailty index (mFI), 5-item mFI, adult spinal deformity frailty index (ASD-FI), FRAIL Scale, and CGA had the most positive ratings for clinimetric properties assessed.

CONCLUSIONS

The assessment of frailty is important in the surgical decision-making process. Cumulative deficit and weighted frailty instruments are appropriate risk stratification tools. Phenotypic tools are sensitive for capturing the relationship between spinal pathology, spine surgery, and prehabilitation on frailty trajectory. CGA instruments are appropriate screening tools for identifying health deficits susceptible to improvement and guiding optimization strategies. Studies are needed to determine whether spine surgery and prehabilitation are effective interventions to reverse frailty.

Understanding the implementation of interventions to improve the management of frailty in primary care: a rapid realist review

OBJECTIVE

Identifying and managing the needs of frail people in the community is an increasing priority for policy makers. We sought to identify factors that enable or constrain the implementation of interventions for frail older persons in primary care.

DESIGN

A rapid realist review.

DATA SOURCES

Cochrane Library, SCOPUS and EMBASE, and grey literature. The search was conducted in September 2019 and rerun on 8 January 2022.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We considered all types of empirical studies describing interventions targeting frailty in primary care.

ANALYSIS

We followed the Realist and Meta-narrative Evidence Syntheses: Evolving Standards quality and publication criteria for our synthesis to systematically analyse and synthesise the existing literature and to identify (intervention-context-mechanism-outcome) configurations. We used normalisation processes theory to illuminate mechanisms surrounding implementation.

RESULTS

Our primary research returned 1755 articles, narrowed down to 29 relevant frailty intervention studies conducted in primary care. Our review identified two families of interventions. They comprised: (1) interventions aimed at the comprehensive assessment and management of frailty needs; and (2) interventions targeting specific frailty needs. Key factors that facilitate or inhibit the translation of frailty interventions into practice related to the distribution of resources; patient engagement and professional skill sets to address identified need.

CONCLUSION

There remain challenges to achieving successful implementation of frailty interventions in primary care. There were a key learning points under each family. First, targeted allocation of resources to address specific needs allows a greater alignment of skill sets and reduces overassessment of frail individuals. Second, earlier patient involvement may also improve intervention implementation and adherence.

Health outcomes and implementation barriers and facilitators of comprehensive geriatric assessment in community settings: a systematic integrative review [PROSPERO registration no.: CRD42021229953]

Background

Comprehensive geriatric assessment (CGA) addresses the bio-psycho-social needs of older adults through multidimensional assessments and management. Synthesising evidence on quantitative health outcomes and implementation barriers and facilitators would inform practice and policy on CGA for community-dwelling older adults.

Methods

We systematically searched four medical and social sciences electronic databases for quantitative, qualitative, and mixed methods studies published from 1 January 2000 to 31 October 2020. Due to heterogeneity of articles, we narratively reviewed the synthesis of evidence on health outcomes and implementation barriers and facilitators.

Results

We screened 14,151 titles and abstracts and 203 full text articles, and included 43 selected articles. Study designs included controlled intervention studies (n = 31), pre-post studies without controls (n = 4), case-control (n = 1), qualitative methods (n = 3), and mixed methods (n = 4). A majority of articles studied populations aged ≥75 years (n = 18, 42%). CGAs were most frequently conducted in the home (n = 25, 58%) and primary care settings (n = 8, 19%). CGAs were conducted by nurses in most studies (n = 22, 51%). There was evidence of improved functional status (5 of 19 RCTs, 2 of 3 pre-post), frailty and fall outcomes (3 of 6 RCTs, 1 of 1 pre-post), mental health outcomes (3 of 6 RCTs, 2 of 2 pre-post), self-rated health (1 of 6 RCTs, 1 of 1 pre-post), and quality of life (4 of 17 RCTs, 3 of 3 pre-post). Barriers to implementation of CGAs involved a lack of partnership alignment and feedback, poor acceptance of preventive work, and challenges faced by providers in operationalising and optimising CGAs. The perceived benefits of CGA that served to facilitate its implementation included the use of highly skilled staff to provide holistic assessments and patient education, and the resultant improvements in care coordination and convenience to the patients, particularly where home-based assessments and management were performed.

Conclusion

There is mixed evidence on the quantitative health outcomes of CGA on community-dwelling older adults. While there is perceived positive value from CGA when carried out by highly skilled staff, barriers such as bringing providers into a partnership, greater acceptance of preventive care, and operational issues could impede its implementation.

What long-term care interventions have been published between 2010 and 2020? Results of a WHO scoping review identifying long-term care interventions for older people around the world

OBJECTIVE

The global population is rapidly ageing. To tackle the increasing prevalence of older adults' chronic conditions, loss of intrinsic capacity and functional ability, long-term care interventions are required. The study aim was to identify long-term care interventions reported in scientific literature from 2010 to 2020 and categorise them in relation to WHO's public health framework of healthy ageing.

DESIGN

Scoping review conducted on PubMed, CINHAL, Cochrane and Google Advanced targeting studies reporting on long-term care interventions for older and frail adults. An internal validated Excel matrix was used for charting.Setting nursing homes, assisted care homes, long-term care facilities, home, residential houses for the elderly and at the community.

INCLUSION CRITERIA

Studies published in peer-reviewed journals between 1 January 2010 to 1 February 2020 on implemented interventions with outcome measures provided in the settings mentioned above for subjects older than 60 years old in English, Spanish, German, Portuguese or French.

RESULTS

305 studies were included. Fifty clustered interventions were identified and organised into four WHO Healthy Ageing domains and 20 subdomains. All interventions delved from high-income settings; no interventions from low-resource settings were identified. The most frequently reported interventions were multimodal exercise (n=68 reports, person-centred assessment and care plan development (n=22), case management for continuum care (n=16), multicomponent interventions (n=15), psychoeducational interventions for caregivers (n=13) and interventions mitigating cognitive decline (n=13).

CONCLUSION

The identified interventions are diverse overarching multiple settings and areas seeking to prevent, treat and improve loss of functional ability and intrinsic capacity. Interventions from low-resource settings were not identified.

Emergency room evaluation and recommendations for older emergency department users: results of the ER2 experimental study

PURPOSE

The study aims to examine whether the use of "emergency room evaluation and recommendations" (ER²) tool in daily ED practice reduces the length of stay in ED and hospital, and hospital admission in older patients visiting ED on stretcher.

METHODS

A total of 3931 older patients visiting ED of the Jewish General Hospital (Montreal, Quebec, Canada) on stretcher were recruited in this non-randomized, pre-post intervention, single arm, prospective and longitudinal open-label trial. ED staff and patients were blinded of the ER² score and patients received usual ED care over the observational phase, whereas ED staff were informed about the ER² score and patients had usual care plus interventions based on tailor-made geriatric recommendations during the interventional phase. The length of stay in ED and in hospital, and hospital admission were the outcomes.

RESULTS

The ER² recommendations were associated with increased length of stay in ED (β = 2.94 with P ≤ 0.001) and decreased length of stay in hospital (β = - 2.07 with P = 0.011). No effect was found for hospital admission (Odd Ratio (OR) = 0.92 with P = 0.182).

CONCLUSION

Emergency room evaluation and recommendations (ER²) tool had mixed effects. Shorter hospital stay has been reported for older ED users hospitalized, but increased ED stay and no effects on hospital admission were found.

Promoting neuroplasticity and neuropsychological functioning in frailty through an app-based sensorimotor training: study protocol for a randomized trial

BACKGROUND

Frailty is characterized by an age-related decline in multiple physiological systems, leading to a high vulnerability to stressors, adverse health outcomes, and low quality of life. Neuroscientific models of pathological aging emphasize the loss of sensorimotor stimulation and reduced neuromodulatory capacities as core processes in age-related cognitive and bodily decline, which may be associated with maladaptive plastic changes in the brain. We plan to increase sensorimotor stimulation in frail persons through a newly developed app-based training program and link the training trials to biological and psychological correlates of age-associated vulnerability and health indices.

METHODS

We will conduct a randomized trial, applying an app-based sensorimotor home training (N = 30) in people suffering from frailty. An app-based relaxation training will serve as an active control condition (N = 30). Both interventions will last for 90 days each. The sensorimotor training includes unimodal and multimodal sensory discrimination tasks in the visual, auditory, and tactile domain, as well as sensorimotor precision tasks. The tasks will be implemented using an adaptive training algorithm and enriched with motivational components embedded in a virtual training environment. We expect a pre-post reduction of frailty status and associated functional decline related to refinement of representational maps within the sensorimotor system and improved sensorimotor function such as extremity function. Secondary analyses will study the influence of BDNF genotype as moderating variable. Additional outcomes will include measures of perceptual and cognitive functioning, quality of life as well as BDNF serum levels. Measurements will take place before training (baseline), after 60 days (assessment 1), and at the end of the training after 90 days (assessment 2).

DISCUSSION

In our randomized trial, we aim to characterize a multidimensional concept of frailty and to target maladaptive behaviors and neuroplasticity using an app-based sensorimotor training. This type of intervention might provide further knowledge and new possibilities for preventing decline and preserving function in older adults.

Application of mesenchymal stem cell therapy for aging frailty: from mechanisms to therapeutics

Aging frailty is a complex geriatric syndrome that becomes more prevalent with advancing age. It constitutes a major health problem due to frequent adverse outcomes. Frailty is characterized by disruption of physiological homeostasis and progressive decline of health status. Multiple factors contribute to development of frailty with advancing age, including genome instability, DNA damage, epigenetic alternations, stem cell exhaustion, among others. These interrelated factors comprehensively result in loss of tissue homeostasis and diminished reserve capacity in frailty. Therefore, the aged organism gradually represents symptoms of frailty with decline in physiological functions of organs. Notably, the brain, cardiovascular system, skeletal muscle, and endocrine system are intrinsically interrelated to frailty. The patients with frailty may display the diminished reserves capacity of organ systems. Due to the complex pathophysiology, no specific treatments have been approved for prevention of this syndrome. At such, effective strategies for intervening in pathogenic process to improve health status of frail patients are highly needed. Recent progress in cell-based therapy has greatly contributed to the amelioration of degenerative diseases related to age. Mesenchymal stem cells (MSCs) can exert regenerative effects and possess anti-inflammatory properties. Transplantation of MSCs represents as a promising therapeutic strategy to address the pathophysiologic problems of frail syndrome. Currently, MSC therapy have undergone the phase I and II trials in human subjects that have endorsed the safety and efficacy of MSCs for aging frailty. However, despite these positive results, caution is still needed with regard to potential to form tumors, and further large-scale studies are warranted to confirm the therapeutic efficacy of MSC therapy.

The physical frailty syndrome as a transition from homeostatic symphony to cacophony

Frailty in aging marks a state of decreased reserves resulting in increased vulnerability to adverse outcomes when exposed to stressors. This Perspective synthesizes the evidence on the aging-related pathophysiology underpinning the clinical presentation of physical frailty as a phenotype of a clinical syndrome that is distinct from the cumulative-deficit-based frailty index. We focus on integrating the converging evidence on the conceptualization of physical frailty as a state, largely independent of chronic diseases, that emerges when the dysregulation of multiple interconnected physiological and biological systems crosses a threshold to critical dysfunction, severely compromising homeostasis. Our exegesis posits that the physiology underlying frailty is a critically dysregulated complex dynamical system. This conceptual framework implies that interventions such as physical activity that have multisystem effects are more promising to remedy frailty than interventions targeted at replenishing single systems. We then consider how this framework can drive future research to further understanding, prevention and treatment of frailty, which will likely preserve health and resilience in aging populations.

Management of Frailty: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials

OBJECTIVE

To analyze and determine the comparative effectiveness of interventions targeting frailty prevention or treatment on frailty as a primary outcome and quality of life, cognition, depression, and adverse events as secondary outcomes.

DESIGN

Systematic review and network meta-analysis (NMA).

METHODS

Data sources-Relevant randomized controlled trials (RCTs) were identified by a systematic search of several electronic databases including MEDLINE, EMBASE, CINAHL, and AMED. Duplicate title and abstract and full-text screening, data extraction, and risk of bias assessment were performed. Data extraction-All RCTs examining frailty interventions aimed to decrease frailty were included. Comparators were standard care, placebo, or another intervention. Data synthesis-We performed both standard pairwise meta-analysis and Bayesian NMA. Dichotomous outcome data were pooled using the odds ratio effect size, whereas continuous outcome data were pooled using the standardized mean difference (SMD) effect size. Interventions were ranked using the surface under the cumulative ranking curve (SUCRA) for each outcome. The quality of evidence was evaluated using the GRADE approach.

RESULTS

A total of 66 RCTs were included after screening of 7090 citations and 749 full-text articles. NMA of frailty outcome (including 21 RCTs, 5262 participants, and 8 interventions) suggested that the physical activity intervention, when compared to placebo and standard care, was associated with reductions in frailty (SMD -0.92, 95% confidence interval -1.55, -0.29). According to SUCRA, physical activity intervention and physical activity plus nutritional supplementation were probably the most effective intervention (100% and 71% likelihood, respectively) to reduce frailty. Physical activity was probably the most effective or the second most effective interventions for all included outcomes.

CONCLUSION AND IMPLICATIONS

Physical activity is one of the most effective frailty interventions. The quality of evidence of the current review is low and very low. More robust RCTs are needed to increase the confidence of our NMA results and the quality of evidence.

Association of Prediagnostic Frailty, Change in Frailty Status, and Mortality After Cancer Diagnosis in the Women's Health Initiative

IMPORTANCE

Understanding changes in frailty in relation to cancer diagnosis can inform optimal selection of cancer treatments and survivorship care.

OBJECTIVE

To investigate associations of prediagnostic frailty and change in frailty status with mortality after a cancer diagnosis.

DESIGN, SETTING, AND PARTICIPANTS

This multicenter, prospective cohort study included 7257 community-dwelling, postmenopausal women in the United States who had frailty assessed at the Women's Health Initiative (WHI) enrollment (1993-1998) and the 3-year visit who were subsequently diagnosed as having invasive cancer. The data were analyzed from January 7, 2019, to June, 8, 2020.

EXPOSURE

Frailty scores were defined from validated questionnaire items conceptually aligned with the Fried frailty phenotype, including at least 3 of the following characteristics: self-reported unintentional weight loss, exhaustion, low physical activity, and muscle weakness or impaired walking. Physical function components of the frailty score were updated a median of 10 (range, 1-18) times.

MAIN OUTCOMES AND MEASURES

Using multivariable-adjusted Cox proportional hazards models, this study examined associations of prediagnostic frailty (at the 3-year visit, before cancer diagnosis) and prediagnostic changes in frailty (from enrollment to the 3-year visit) with mortality. Women were followed up beginning from cancer diagnosis for mortality outcomes through March 2018. In linear mixed-effects models with frailty scores as a function of time since cancer diagnosis, this study evaluated whether the time slope, ie, the rate of change in frailty score, increased after cancer diagnosis.

RESULTS

This study included 7257 women in the WHI cohort who completed frailty assessments at enrollment and the 3-year WHI visit before cancer diagnosis and subsequently developed cancer. Cancer cases included 2644 breast cancers (36%), 822 lung cancers (11%), 691 colorectal cancers (10%), 445 endometrial cancers (6%), and 286 ovarian cancers (4%). At the 3-year visit, prior to cancer diagnosis, the mean (SD) age was 63 (7) years, and 1161 of 7257 (16%) of participating women met criteria for frailty; 2129 of 7257 (29%) were prefrail, and 3967 of 7257 (55%) were nonfrail. Over a median follow-up of 5.8 years after cancer diagnosis (range, 1 day to 19.9 years), 3056 women died. After multivariable adjustment, women who were frail (vs nonfrail) before cancer diagnosis had an increased risk of mortality after cancer diagnosis (hazard ratio [HR], 1.40; 95% CI, 1.26-1.55; P for trend <.001). Sustained frailty (21% [1537 of 7257] of women) or worsening frailty (22% [1578 of 7257]) vs being consistently nonfrail (45% [3266 of 7257]) before cancer diagnosis increased the risk of mortality after cancer diagnosis (HR, 1.25; 95% CI, 1.14-1.38 and 1.22; 95% CI, 1.11-1.34, respectively; P for trend <.001). In linear mixed-effects models, the rate of increase in physical frailty over time was statistically significantly higher after cancer diagnosis.

CONCLUSIONS AND RELEVANCE

Sustained and worsening frailty before cancer diagnosis was associated with an increased risk of mortality after cancer diagnosis in postmenopausal women. Furthermore, the rate of decline in physical function accelerated after cancer diagnosis. Frailty assessment could provide valuable information and perhaps prompt interventions to reduce and preempt worsening of physical frailty after cancer diagnosis.

Current evidence on the impact of medication optimization or pharmacological interventions on frailty or aspects of frailty: a systematic review of randomized controlled trials

Background

Frailty and adverse drug effects are linked in the fact that polypharmacy is correlated with the severity of frailty; however, a causal relation has not been proven in older people with clinically manifest frailty.

Methods

A literature search was performed in Medline to detect prospective randomized controlled trials (RCTs) testing the effects of pharmacological interventions or medication optimization in older frail adults on comprehensive frailty scores or partial aspects of frailty that were published from January 1998 to October 2019.

Results

Twenty-five studies were identified, 4 on comprehensive frailty scores and 21 on aspects of frailty. Two trials on comprehensive frailty scores showed positive results on frailty although the contribution of medication review in a multidimensional approach was unclear. In the studies on aspects related to frailty, ten individual drug interventions showed improvement in physical performance, muscle strength or body composition utilizing alfacalcidol, teriparatide, piroxicam, testosterone, recombinant human chorionic gonadotropin, or capromorelin. There were no studies examining negative effects of drugs on frailty.

Conclusion

So far, data on a causal relationship between drugs and frailty are inconclusive or related to single-drug interventions on partial aspects of frailty. There is a clear need for RCTs on this topic that should be based on a comprehensive, internationally consistent and thus reproducible concept of frailty assessment.

Exploring health-related quality of life and frailty in older adults based on the Korean Frailty and Aging Cohort Study

PURPOSE

The study aimed to analyze the association between frailty and health-related quality of life (HRQOL) based on the Korean Frailty and Aging Cohort Study.

METHODS

In this cross-sectional study, 2905 adults aged 70 to 84 years were enrolled. Frailty was determined according to the Fried frailty index. HRQOL was measured using the 5-level EuroQol questionnaire (EQ-5D-5L) and the 12-item Short-Form Health Survey version 2 (SF-12). Hierarchical linear regressions were conducted to examine the relationship between frailty and HRQOL and a logistic regression analysis was performed to estimate odds ratios of frailty status in the scores of the lowest quartiles in each scale.

RESULTS

Of the total respondents, 7.8% were frail, 47.0% were pre-frail, and 45.2% were robust. Frail respondents had significantly lower HRQOL scores than robust respondents, especially for EQ-5D-5L utility weights (0.74 vs 0.93). Frailty was strongly associated with decreased HRQOL in both physical and mental component summary of SF-12 (p < 0.001). Both pre-frail and frail states were related to greater odds of scoring in the bottom 25% of HRQOL scales compared to the non-frail state (p < 0.0001).

CONCLUSION

Frailty was associated with declined HRQOL in Korean older adults. This result recommends raising awareness about identifying and preventing frailty for better quality of life in the Korean elderly population.

Primary care interventions to address physical frailty among community-dwelling adults aged 60 years or older: A meta-analysis

Introduction

The best interventions to address frailty among older adults have not yet been fully defined, and the diversity of interventions and outcome measures makes this process challenging. Consequently, there is a lack of guidance for clinicians and researchers regarding which interventions are most likely to help older persons remain robust and independent. This paper uses meta-analysis to assess effectiveness of primary care interventions for physical frailty among community-dwelling adults aged 60+ and provides an up-to-date synthesis of literature in this area.

Methods

PubMed, CINAHL, Cochrane Register of Controlled Trials, and PEDro databases were searched, and RCTs, controlled pilot studies, or trials with similar study designs addressing frailty in the primary care setting among persons aged 60+ were chosen. Study data was abstracted following PRISMA guidelines, then meta-analysis was performed using the random effects model.

Results

31 studies with a total of 4794 participants were analysed. Interventions using predominantly resistance-based exercise and nutrition supplementation seemed to improve frailty status versus control (RR = 0.62 (CI 0.48–0.79), I² = 0%). Exercise plus nutrition education also reduced frailty (RR = 0.69 (CI 0.58–0.82), I² = 0%). Exercise alone seemed effective in reducing frailty (RR = 0.63 (CI 0.47–0.84), I² = 0%) and improving physical performance (RR = 0.43 (CI 0.18–0.67), I² = 0%). Exercise alone also appeared superior to control in improving gait speed (SMD = 0.36 (CI 0.10–0.61, I² = 74%), leg strength (SMD = 0.61 (CI 0.09–1.13), I² = 87%), and grip strength (Mean Difference = 1.08 (CI 0.02–2.15), I² = 71%) though a high degree of heterogeneity was observed. Comprehensive geriatric assessment (RR = 0.77 (CI 0.64–0.93), I² = 0%) also seemed superior to control in reducing frailty.

Conclusion

Exercise alone or with nutrition supplementation or education, and comprehensive geriatric assessment, may reduce physical frailty. Individual-level factors and health systems resource availability will likely determine configuration of future interventions.

The application of artificial intelligence (AI) techniques to identify frailty within a residential aged care administrative data set

INTRODUCTION

Research has shown that frailty, a geriatric syndrome associated with an increased risk of negative outcomes for older people, is highly prevalent among residents of residential aged care facilities (also called long term care facilities or nursing homes). However, progress on effective identification of frailty within residential care remains at an early stage, necessitating the development of new methods for accurate and efficient screening.

OBJECTIVES

We aimed to determine the effectiveness of artificial intelligence (AI) algorithms in accurately identifying frailty among residents aged 75 years and over in comparison with a calculated electronic Frailty Index (eFI) based on a routinely-collected residential aged care administrative data set drawn from 10 residential care facilities located in Queensland, Australia. A secondary objective included the identification of best-performing candidate algorithms.

METHODS

We designed a frailty prediction system based on the eFI identification of frailty, allocating 84.5 % and 15.5 % of the data to training and test data sets respectively. We compared the performance of 18 specific scenarios to predict frailty against eFI based on unique combinations of three ML algorithms (support vector machines [SVM], decision trees [DT] and K-nearest neighbours [KNN]) and six cases (6, 10, 11, 14, 39 and 70 input variables). We calculated accuracy, percentage positive and negative agreement, sensitivity, specificity, Cohen's kappa and Prevalence- and Bias- Adjusted Kappa (PABAK), table frequencies and positive and negative predictive values.

RESULTS

Of 592 eligible resident records, 500 were allocated to the training set and 92 to the test set. Three scenarios (10, 11 and 70 input variables), all based on SVM algorithm, returned overall accuracy above 75 %.

CONCLUSIONS

There is some potential for AI techniques to contribute towards better frailty identification within residential care. However, potential benefits will need to be weighed against administrative burden, data quality concerns and presence of potential bias.

Implementation of Geriatric Recommendations by Doctors: A Comparison of Models of Geriatric Assessment for Mobile and Home-Ridden Patients

In the present study we assessed the rate of implementation of recommendations given following geriatric assessment for home-ridden patients; a retrospective review of medical records to evaluate the implementation of geriatric recommendations given to patients in the Home Geriatric Service (HGS) between 2015 and 2016. The patients were categorized into two groups: the HGS-clinic (HGS-C) group, in which the primary care physician was responsible for implementation of the recommendations, and the HGS-home care (HGS-H) group, in which the responsibility for implementation of the recommendations was on the geriatrician. The results were compared with the implementation of recommendations in other ambulatory models for mobile patients-Clinic-Based Geriatric Assessment Services (CBGAS). The study included 865 patients. The highest rate of implementation was in the HGS-H group (85.7%), compared with 66.6% in the HGS-C group and 52.7% in the CBGAS group (p < 0.0001). In the logistic regression model for prediction of patients with implementation rates above 75%, the only variable that entered the prediction model was affiliation with the HGS-H group (odds ratio [OR] = 4.8, 95% confidence interval [CI] 2.3-9.6, p < 0.0001) or the HGS-C group (OR = 1.7, 95% CI 1.0-2.9, p = 0.046). The implementation rate for geriatric recommendations is higher for home-ridden patients compared with mobile patients, with the maximum recommendation rate in the subgroup, where geriatricians implemented the recommendations themselves. These findings raise the possibility that the most successful model, in terms of the implementation of recommendations, is the model in which implementation is carried out by the same staff that conducted the assessment.

Effectiveness of interventions to prevent pre-frailty and frailty progression in older adults: a systematic review

OBJECTIVE

To summarize the best available evidence regarding the effectiveness of interventions for preventing frailty progression in older adults.

INTRODUCTION

Frailty is an age-related state of decreased physiological reserves characterized by an increased risk of poor clinical outcomes. Evidence supporting the malleability of frailty, its prevention and treatment, has been presented.

INCLUSION CRITERIA

The review considered studies on older adults aged 65 and over, explicitly identified as pre-frail or frail, who had been undergoing interventions focusing on the prevention of frailty progression. Participants selected on the basis of specific illness or with a terminal diagnosis were excluded. The comparator was usual care, alternative therapeutic interventions or no intervention. The primary outcome was frailty. Secondary outcomes included: (i) cognition, quality of life, activities of daily living, caregiver burden, functional capacity, depression and other mental health-related outcomes, self-perceived health and social engagement; (ii) drugs and prescriptions, analytical parameters, adverse outcomes and comorbidities; (iii) costs, and/or costs relative to benefits and/or savings associated with implementing the interventions for frailty. Experimental study designs, cost effectiveness, cost benefit, cost minimization and cost utility studies were considered for inclusion.

METHODS

Databases for published and unpublished studies, available in English, Portuguese, Spanish, Italian and Dutch, from January 2001 to November 2015, were searched. Critical appraisal was conducted using standardized instruments from the Joanna Briggs Institute. Data was extracted using the standardized tools designed for quantitative and economic studies. Data was presented in a narrative form due to the heterogeneity of included studies.

RESULTS

Twenty-one studies, all randomized controlled trials, with a total of 5275 older adults and describing 33 interventions, met the criteria for inclusion. Economic analyses were conducted in two studies. Physical exercise programs were shown to be generally effective for reducing or postponing frailty but only when conducted in groups. Favorable effects on frailty indicators were also observed after the interventions, based on physical exercise with supplementation, supplementation alone, cognitive training and combined treatment. Group meetings and home visits were not found to be universally effective. Lack of efficacy was evidenced for physical exercise performed individually or delivered one-to-one, hormone supplementation and problem solving therapy. Individually tailored management programs for clinical conditions had inconsistent effects on frailty prevalence. Economic studies demonstrated that this type of intervention, as compared to usual care, provided better value for money, particularly for very frail community-dwelling participants, and had favorable effects in some of the frailty-related outcomes in inpatient and outpatient management, without increasing costs.

CONCLUSIONS

This review found mixed results regarding the effectiveness of frailty interventions. However, there is clear evidence on the usefulness of such interventions in carefully chosen evidence-based circumstances, both for frailty itself and for secondary outcomes, supporting clinical investment of resources in frailty intervention. Further research is required to reinforce current evidence and examine the impact of the initial level of frailty on the benefits of different interventions. There is also a need for economic evaluation of frailty interventions.

Frailty Prevalence and Association with Health-Related Quality of Life Impairment among Rural Community-Dwelling Older Adults in Vietnam

Measuring health-related quality of life (HRQOL) is critical to evaluate the burden of frailty in the older population.This study explored the prevalence of frailty among Vietnamese older people in rural communities, determined the factors associated with frailty, and examined the differences in HRQOL between non-frail, pre-frail, and frail people. A cross-sectional study was conducted on older adults (≥60 years old) residing in Soc Son district, northern Vietnam. Non-frailty, pre-frailty, and frailty conditions were evaluated using Fried’s frailty criteria. The EuroQol-5 Dimensions-5 Levels(EQ-5D-5L) instrument was employed to measure HRQOL. Socioeconomic, behavioral, health status, and healthcare utilization characteristics were collected as covariates. Among 523 older adults, 65.6% were pre-frail, and 21.7% were frail. The mean EQ-5D-5L indexes of the non-frailty, pre-frailty, and frailty groups were 0.70 (SD = 0.18), 0.70 (SD = 0.19), and 0.58 (SD = 0.20), respectively. The differences were found between non-frailty and frailty groups (p < 0.01), as well as the pre-frailty and frailty groups (p<0.01). After adjusting for covariates, the estimated mean difference in the HRQOL between the non-frailty and frailty groups was −0.10 (95%CI= −0.17; −0.02) (R² = 45.2%), showing a 10% reduction of the maximum EQ-5D-5L index.This study emphasized the high prevalence of frailty among older adults in the rural communities of Vietnam. Frailty was found to be associated with a small reduction of HRQOL in this population.

Comprehensive Geriatric Assessment: Interprofessional Team Recommendations for Older Adult Women With Breast Cancer

BACKGROUND

Geriatric oncology incorporates comprehensive geriatric assessment (CGA) and traditional oncology care.

OBJECTIVES

The aims are to identify limitations reflected by mean scores on the CGA instruments and describe the CGA recommendations documented in the medical record.

METHODS

CGA was administered and consisted of the Timed Up and Go Test, the Activities of Daily Living Scale, the Instrumental Activities of Daily Living Scale, grip strength, falls, pain, the Brief Fatigue Inventory, the Pittsburgh Sleep Quality Index, the Geriatric Depression Scale, the Mini-Cog, and the Mini Nutritional Assessment. CGA recommendations were obtained from the medical record. Descriptive statistics were used to analyze the data.

FINDINGS

Most recommendations were for general cancer treatment, followed by fall referral/education.

Occupational Therapy Interventions to Improve Activities of Daily Living for Community-Dwelling Older Adults: A Systematic Review

OBJECTIVE

This systematic review aimed to synthesize the effects of interventions within the scope of occupational therapy to improve performance of activities of daily living (ADLs) in community-dwelling older adults.

METHOD

Searches were conducted in CINAHL, the Cochrane Database of Systematic Reviews, MEDLINE, PsycINFO, and OTseeker. Empirical studies published between 1995 and 2015 were individually screened and appraised by two reviewers.

RESULTS

Forty-three studies met the review inclusion and exclusion criteria. Physical exercise was the most common intervention approach. Physical exercise interventions for frail older adults showed a moderate benefit, but no benefits were found for older adults without noticeable difficulty in ADLs. For older adults with difficulty in ADLs, there was a high benefit of using home-based intervention.

CONCLUSION

The findings of this systematic review highlight the importance of addressing older adults' living environment in intervention to promote independence in ADLs.

Generational Distinctions on the Importance of Age-Friendly Community Features by Older Age Groups

In 2006, the World Health Organization initiated an international movement to enhance active aging and the age-friendliness of communities by focusing efforts on the built, social, and service environment. The global model requires soliciting older adults’ preferences regarding community features although findings are typically aggregated across all aged respondents despite mounting distinctions between the generations. This study aimed to examine the differential salience of community features by older generational age groups including Baby Boomers ( n = 639) and Silent and Government or General Issued (GI) Generation ( n = 488) in an age-friendly community in which more than half of its residents are age 50 or older. Chi-square results indicate significant differences across the generational age groups in all domains with the greatest distinctions pertaining to preferences in housing, outdoor spaces, employment, and participation in varied social activities. The perceptions expressed by Boomer-aged adults portend implications ahead for multiple sectors and features of community life.

Effects of physical activity interventions in frail and prefrail community-dwelling people on frailty status, muscle strength, physical performance and muscle mass-a narrative review

Background

Frailty is a geriatric syndrome, which is highly prevalent in community-dwelling older adults and is associated with a variety of unwanted health outcomes, including dependency and institutionalization. Physical activity (PA) interventions may be of great importance in frail people to improve the frailty status, muscle strength, physical performance and muscle mass.

Methods

A narrative review of randomized-controlled trails was performed, including frail and prefrail community-dwelling older adults. Included were studies with different PA interventions, such as aerobic activity, strength and balance training, stretching, and a combination of these methods.

Results

Overall, 14 studies were included. The PA interventions led to a significant reduction in the frailty status (3/5 studies), to an increase in muscle strength (4/8 studies), to improved physical performance (7/11 studies), and to an increase in muscle mass (1/4 studies), when compared to the control group. The studies analyzed differed in various aspects of study protocols (training protocol, intensity, frequency, follow-up time, measuring tools) and delivery method of intervention (health professionals, lay volunteers, at home in health care institutions).

Conclusions

Although it was not consistently reported in the studies that PA interventions are successful in increasing muscle mass in frail and prefrail older people, the results support the effectiveness of PA interventions on the reduction of frailty, and the increase in muscle strength and physical performance.

The feasibility of assessing frailty and sarcopenia in hospitalised older people: a comparison of commonly used tools

Background

Frailty and sarcopenia are common amongst hospitalised older people and associated with poor healthcare outcomes. Widely recognised tools for their identification are the Fried Frailty Phenotype, its self-report version the FRAIL Scale, and the European Working Group on Sarcopenia in Older People (EWGSOP) criteria. We studied the feasibility of using these tools in a hospital setting of acute wards for older people.

Methods

Patients aged 70+ years admitted to acute wards at one English hospital were prospectively recruited. The Fried Frailty Phenotype was assessed through measured grip strength, gait speed and questions on unintentional weight loss, exhaustion and physical activity. The 5-item self-reported FRAIL scale questionnaire covering the same domains was completed. Agreement between the two tools was reported using the Cohen kappa statistic. The EWGSOP criteria (gait speed, grip strength and muscle mass) were assessed by additional bedside measurement of muscle mass with bioelectrical impedance.

Results

Two hundred thirty three participants (median age 80 years, 60% men) were recruited. Most (221, 95%) had their grip strength measured: 4 (2%) were unable and data were missing for 8 (3%). Only 70 (30%) completed the gait speed assessment: 153 (66%) were unable with missing data on 10 (4%). 113 (49%) participants had the bioelectrical impedance assessment. Muscle mass measurement was not possible for 84 (36%) participants: 25 patients declined, 21 patients were unavailable, 22 results were technically invalid, and 16 had clinical contra-indications. Data on 36 (15%) were missing.

Considering inability to complete grip strength or gait speed assessments as low values, data for the Fried Frailty Phenotype was available for 218 (94%) of participants; frailty was identified in 105 (48%). 230 (99%) patients completed the FRAIL scale; frailty was identified among 77 (34%). There was moderate agreement between the two frailty tools (Kappa value of 0.46, 95%CI: 0.34 to 0.58). Complete data for the EWGOSP criteria were only available for 124 (53%) patients of whom 40 (32%) had sarcopenia.

Conclusion

It was feasible to measure grip strength and complete the FRAIL scale among older inpatients in hospital. Measuring gait speed and muscle mass to identify sarcopenia was challenging in the acute setting.

Should we screen for frailty in primary care settings? A fresh perspective on the frailty evidence base: A narrative review

With older adults living longer, health service providers have increasingly turned their attention towards frailty and its significant consequences for health and well-being. Consequently, frailty screening has gained momentum as a possible health policy answer to the question of what can be done to prevent frailty's onset and progression. However, who should be screened for frailty, where and when remains a subject of extensive debate. The purpose of this narrative review is to explore the dimensions of this question with reference to Wilson and Jungner's time-tested and widely accepted principles for acceptable screening within community settings. Although the balance of the emerging evidence to support frailty screening is promising, significant gaps in the evidence base remain. Consequently, when assessed against Wilson and Jungner's principles, extensive population screening does not appear to be supported by the evidence. However, screening for the purpose of case-finding may prove useful among older adults.

Prediction of unplanned hospital admissions in older community dwellers using the 6-item Brief Geriatric Assessment: Results from REPERAGE, an observational prospective population-based cohort study

BACKGROUND

The 6-item Brief Geriatric Assessment (BGA) provides a priori risk stratification of incident hospital health adverse events, but it has not been used yet to assess the risk of unplanned hospital admission for older patients in primary care. This study aims to examine the association between the a priori risk stratification levels of the 6-item BGA performed by general practitioners (GPs) and incident unplanned hospital admissions in older community patients.

METHODS

Based on an observational prospective cohort design, 668 participants (mean age 84.7 ± 3.9 years; 64.7% female) were recruited by their GPs during an index primary care visit. The 6-item BGA was completed at baseline and provided an a priori risk stratification in three levels (low, moderate, high). Incident unplanned hospital admissions were recorded during a 6-month follow-up.

RESULTS

The incidence of unplanned hospital admissions increased with the risk level of the 6-item BGA stratification, the highest prevalence (35.3%) being reported with the high-risk level (P = 0.001). The risk of unplanned hospital admission at the high-risk level was significant (crude odds ratio (OR) = 5.48, P = 0.001 and fully adjusted OR = 3.71, P = 0.032, crude hazard ratio (HR) = 4.20; P = 0.002 and fully adjusted HR = 2.81; P = 0.035). The Kaplan-Meier's distributions of incident unplanned hospital admissions differed significantly between the three risk levels (P-value = 0.002). Participants with a high-risk level were more frequently admitted to hospital than those at a low-risk level (P = 0.001). Criteria performances of all risk levels were poor, except the specificity of the high-risk level, which was 98.2%.

CONCLUSIONS

The a priori 6-item BGA risk stratification was significantly associated with incident unplanned hospital admissions in primary care older patients. However, except for the specificity of the high-risk level, its criteria performances were poor, suggesting that this tool is unsuitable for screening older patients in primary care settings at risk of unplanned hospital admission.

Physical Frailty: ICFSR International Clinical Practice Guidelines for Identification and Management

OBJECTIVE

The task force of the International Conference of Frailty and Sarcopenia Research (ICFSR) developed these clinical practice guidelines to overview the current evidence-base and to provide recommendations for the identification and management of frailty in older adults.

METHODS

These recommendations were formed using the GRADE approach, which ranked the strength and certainty (quality) of the supporting evidence behind each recommendation. Where the evidence-base was limited or of low quality, Consensus Based Recommendations (CBRs) were formulated. The recommendations focus on the clinical and practical aspects of care for older people with frailty, and promote person-centred care. Recommendations for Screening and Assessment: The task force recommends that health practitioners case identify/screen all older adults for frailty using a validated instrument suitable for the specific setting or context (strong recommendation). Ideally, the screening instrument should exclude disability as part of the screening process. For individuals screened as positive for frailty, a more comprehensive clinical assessment should be performed to identify signs and underlying mechanisms of frailty (strong recommendation). Recommendations for Management: A comprehensive care plan for frailty should address polypharmacy (whether rational or nonrational), the management of sarcopenia, the treatable causes of weight loss, and the causes of exhaustion (depression, anaemia, hypotension, hypothyroidism, and B12 deficiency) (strong recommendation). All persons with frailty should receive social support as needed to address unmet needs and encourage adherence to a comprehensive care plan (strong recommendation). First-line therapy for the management of frailty should include a multi-component physical activity programme with a resistance-based training component (strong recommendation). Protein/caloric supplementation is recommended when weight loss or undernutrition are present (conditional recommendation). No recommendation was given for systematic additional therapies such as cognitive therapy, problem-solving therapy, vitamin D supplementation, and hormone-based treatment. Pharmacological treatment as presently available is not recommended therapy for the treatment of frailty.

Delaying and reversing frailty: a systematic review of primary care interventions

BACKGROUND

Recommendations for routine frailty screening in general practice are increasing as frailty prevalence grows. In England, frailty identification became a contractual requirement in 2017. However, there is little guidance on the most effective and practical interventions once frailty has been identified.

AIM

To assess the comparative effectiveness and ease of implementation of frailty interventions in primary care.

DESIGN AND SETTING

A systematic review of frailty interventions in primary care.

METHOD

Scientific databases were searched from inception to May 2017 for randomised controlled trials or cohort studies with control groups on primary care frailty interventions. Screening methods, interventions, and outcomes were analysed in included studies. Effectiveness was scored in terms of change of frailty status or frailty indicators and ease of implementation in terms of human resources, marginal costs, and time requirements.

RESULTS

A total of 925 studies satisfied search criteria and 46 were included. There were 15 690 participants (median study size was 160 participants). Studies reflected a broad heterogeneity. There were 17 different frailty screening methods. Of the frailty interventions, 23 involved physical activity and other interventions involved health education, nutrition supplementation, home visits, hormone supplementation, and counselling. A significant improvement of frailty status was demonstrated in 71% (n = 10) of studies and of frailty indicators in 69% (n=22) of studies where measured. Interventions with both muscle strength training and protein supplementation were consistently placed highest for effectiveness and ease of implementation.

CONCLUSION

A combination of muscle strength training and protein supplementation was the most effective intervention to delay or reverse frailty and the easiest to implement in primary care. A map of interventions was created that can be used to inform choices for managing frailty.

Novel mHealth App to Deliver Geriatric Assessment-Driven Interventions for Older Adults With Cancer: Pilot Feasibility and Usability Study

Background

Older patients with cancer are at an increased risk of adverse outcomes. A geriatric assessment (GA) is a compilation of reliable and validated tools to assess domains that are predictors of morbidity and mortality, and it can be used to guide interventions. However, the implementation of GA and GA-driven interventions is low due to resource and time limitations. GA-driven interventions delivered through a mobile app may support the complex needs of older patients with cancer and their caregivers.

Objective

We aimed to evaluate the feasibility and usability of a novel app (TouchStream) and to identify barriers to its use. As an exploratory aim, we gathered preliminary data on symptom burden, health care utilization, and satisfaction.

Methods

In a single-site pilot study, we included patients aged ≥65 years undergoing treatment for systemic cancer and their caregivers. TouchStream consists of a mobile app and a Web portal. Patients underwent a GA at baseline with the study team (on paper), and the results were used to guide interventions delivered through the app. A tablet preloaded with the app was provided for use at home for 4 weeks. Feasibility metrics included usability (system usability scale of >68 is considered above average), recruitment, retention (number of subjects consented who completed postintervention assessments), and percentage of days subjects used the app. For the last 8 patients, we assessed their symptom burden (severity and interference with 17-items scored from 0-10 where a higher score indicates worse symptoms) using a clinical symptom inventory, health care utilization from the electronic medical records, and satisfaction (6 items scored on a 5-point Likert Scale for both patients and caregivers where a higher score indicates higher satisfaction) using a modified satisfaction survey. Barriers to use were elicited through interviews.

Results

A total of 18 patients (mean age 76.8, range 68-87) and 13 caregivers (mean age 69.8, range 38-81) completed the baseline assessment. Recruitment and retention rates were 67% and 80%, respectively. The mean SUS score was 74.0 for patients and 72.2 for caregivers. Mean percentage of days the TouchStream app was used was 78.7%. Mean symptom severity and interference scores were 1.6 and 2.8 at preintervention, and 0.9 and 1.5 at postintervention, respectively. There was a total of 27 clinic calls during the intervention period and 15 during the postintervention period (week 5-8). One patient was hospitalized during the intervention period (week 1-4) and two patients during the postintervention period (week 5-8). Mean satisfaction scores of patients and caregivers with the mobile app were 20.4 and 23.4, respectively. Barriers fell into 3 themes: general experience, design, and functionality.

Conclusions

TouchStream is feasible and usable for older patients on cancer treatment and their caregivers. Future studies should evaluate the effects of the TouchStream on symptoms and health care utilization in a randomized fashion.

Frailty Screening and Interventions: Considerations for Clinical Practice

Frailty is recognized as a cornerstone of geriatric medicine. It increases the risk of geriatric syndromes and adverse health outcomes in older and vulnerable populations. Although multiple screening instruments have been developed and validated to improve feasibility in clinical practice, frequent lack of agreement between frailty instruments has slowed broad implementation of these tools. Despite this, interventions to improve frailty-related health outcomes developed to date include exercise, nutrition, multicomponent interventions, and individually tailored geriatric care models. Possible strategies to prevent frailty include lifestyle or behavioral interventions, proper nutrition, and increased activity levels and social engagement.

Identifying acceptable components for home-based health promotion services for older people with mild frailty: A qualitative study

Mild frailty is common in later life, increasing the risk of hospitalisation, loss of independence and premature death. Targeted health promotion services may reduce adverse outcomes and increase quality of life; however, effective, well-developed theory-based interventions are lacking. We aimed to explore perceptions of health promotion behaviours undertaken by older people with mild frailty, barriers and facilitators to engagement, and identify potential components for new home-based health promotion services. We carried out 17 semi-structured qualitative interviews and six focus groups with 53 stakeholders, including 14 mildly frail older people, 12 family carers, 19 community health and social care professionals, and 8 homecare workers, in one urban and one semi-rural area of England. Transcripts were thematically analysed. Older people with mild frailty reported engaging in a variety of lifestyle behaviours to promote health and well-being. Key barriers or facilitators to engaging in these included transport, knowledge of local services, social support and acceptance of personal limitations. Older people, carers and professionals agreed that any new service should address social networks and mobility and tailor other content to each individual. Services should aim to increase motivation through focussing on independence and facilitate older people to continue carrying out behaviours that improve their well-being, as well as provide information, motivation, psychological support and practical support. Stakeholders agreed services should be delivered over a sustained period by trained non-specialist workers. New services including these components are likely to be acceptable to older people with mild frailty.

Efficacy of nurse-led and general practitioner-led comprehensive geriatric assessment in primary care: protocol of a pragmatic three-arm cluster randomised controlled trial (CEpiA study)

INTRODUCTION

Older patients raise therapeutic challenges, because they constitute a heterogeneous population with multimorbidity. To appraise this complexity, geriatricians have developed a multidimensional comprehensive geriatric assessment (CGA), which may be difficult to apply in primary care settings. Our primary objective was to compare the effect on morbimortality of usual care compared with two complex interventions combining educational seminars about CGA: a dedicated geriatric hotline for general practitioners (GPs) and CGA by trained nurses or GPs.

METHODS AND ANALYSIS

The Clinical Epidemiology and Ageing study is an open-label, pragmatic, multicentre, three-arm, cluster randomised controlled trial comparing two intervention groups and one control group. Patients must be 70 years or older with a long-term illness or with unscheduled hospitalisation in the past 3 months (750 patients planned). This study involves volunteering GPs practising in French primary care centres, with randomisation at the practice level. The multifaceted interventions for interventional arms comprise an educational interactive multiprofessional seminar for GPs and nurses, a geriatric hotline dedicated to GPs in case of difficulties and the performance of a CGA updated to primary care. The CGA is systematically performed by a nurse in arm 1 but is GP-led on a case-by-case basis in arm 2. The primary endpoint is a composite criterion comprising overall death, unscheduled hospitalisations, emergency admissions and institutionalisation within 12 months after inclusion. Intention-to-treat analysis will be performed using mixed-effects logistic regression models, with adjustment for potential confounders.

ETHICS AND DISSEMINATION

The protocol was approved by an appropriate ethics committee (CPP Ile-de-France IV, Paris, France, approval April 2015;15 664). This study is conducted according to principles of good clinical practice in the context of current care and will provide useful knowledge on the clinical benefits achievable by CGA in primary care.

Management of Frailty at Individual Level - Clinical Management: Systematic Literature Review

Introduction

To deliver quality management of a frail individual, a clinician should understand the concept of frailty, be aware of its epidemiology and be able to screen for frailty and assess it when it is present, and, finally, to recommend successful interventions.

Methodology

A systematic literature search was conducted in the following databases: PubMed, Cochrane, Embase, Cinahl and UpToDate. The criterion in selecting the literature was that articles were published in the period from 2002 to 2017. From 67432 initial hits, 27 publications were selected.

Results

Useful interventions to address frailty are supplementation of vitamin D, proper nutrition, multicomponent training, home-based physiotherapy and comprehensive geriatric assessment, particularly when performed in geriatric wards.

Conclusion

Comprehensive geriatric assessment is an effective way to decrease frailty status especially when performed in geriatric wards. Multicomponent physical training and multidimensional interventions (physical training, nutrition, vitamin D supplementation and cognitive training) are effective measures to reduce frailty.

The effect of complex interventions on supporting self-care among community-dwelling older adults: a systematic review and meta-analysis

Background

self-care is critical to enable community-dwelling older adults to live independently. Complex interventions have emerged as a strategy to support self-care, but their effectiveness is unknown. Our objective was to review systematically their effectiveness on both positive (increased scores in self-rated health, Activities of Daily Living, Instrumental Activities of Daily Living, quality of life) and negative aspects (increased incidence of falls, fear of falling, hospital and nursing home admission, increased depression score), and to determine which intervention components explain the observed effects.

Methods

CINAHL, MEDLINE, British Nursing Index, PsycInfo and Cochrane CENTRAL were searched from January 2006 to October 2016. Randomised controlled trials providing at least two of these components: individual assessment, care planning or provision of information were reviewed. Outcomes were pooled by random-effects meta-analysis.

Results

twenty-two trials with 14,364 participants were included with a low risk of bias. Pooled effects showed significant benefits on positive aspects including self-rated health [standardised mean difference (SMD) 0.09, 95% confidence interval (CI) 0.01-0.17] and the mental subscale of quality of life (SMD 0.44, 95% CI 0.09-0.80) as well as on the negative aspect of incidence of falls [odds ratio (OR) 0.60, 95% CI 0.46-0.79]. There was no significant improvement in ADL, IADL, overall quality of life, fear of falling, reduction in health service utilisation or depression levels. Meta-regression and subgroup analysis did not identify any specific component or characteristic in complex interventions which explained these effects.

Conclusion

based on current evidence, supporting self-care in community-dwelling older adults using complex interventions effectively increases self-rated health, reduces the occurrence of falls and improves the mental subscale of quality of life.

Rationale and design of the allogeneiC human mesenchymal stem cells (hMSC) in patients with aging fRAilTy via intravenoUS delivery (CRATUS) study: A phase I/II, randomized, blinded and placebo controlled trial to evaluate the safety and potential efficacy of allogeneic human mesenchymal stem cell infusion in patients with aging frailty

Frailty is a syndrome associated with reduced physiological reserves that increases an individual's vulnerability for developing increased morbidity and/or mortality. While most clinical trials have focused on exercise, nutrition, pharmacologic agents, or a multifactorial approach for the prevention and attenuation of frailty, none have studied the use of cell-based therapies. We hypothesize that the application of allogeneic human mesenchymal stem cells (allo-hMSCs) as a therapeutic agent for individuals with frailty is safe and efficacious. The CRATUS trial comprises an initial non-blinded phase I study, followed by a blinded, randomized phase I/II study (with an optional follow-up phase) that will address the safety and pre-specified beneficial effects in patients with the aging frailty syndrome. In the initial phase I protocol, allo-hMSCs will be administered in escalating doses via peripheral intravenous infusion (n=15) to patients allocated to three treatment groups: Group 1 (n=5, 20 million allo-hMSCs), Group 2 (n=5, 100 million allo-hMSCs), and Group 3 (n=5, 200 million allo-hMSCs). Subsequently, in the randomized phase, allo-hMSCs or matched placebo will be administered to patients (n=30) randomly allocated in a 1:1:1 ratio to one of two doses of MSCs versus placebo: Group A (n=10, 100 million allo-hMSCs), Group B (n=10, 200 million allo-hMSCs), and Group C (n=10, placebo). Primary and secondary objectives are, respectively, to demonstrate the safety and efficacy of allo-hMSCs administered in frail older individuals. This study will determine the safety of intravenous infusion of stem cells and compare phenotypic outcomes in patients with aging frailty.

Measuring frailty in clinical practice: a comparison of physical frailty assessment methods in a geriatric out-patient clinic

Background

The objectives of this study were to determine: 1) the prevalence of frailty using Fried’s phenotype method and the Short Performance Physical Battery (SPPB), 2) agreement between frailty assessment methods, 3) the feasibility of assessing frailty using Fried’s phenotype method and the SPPB.

Methods

This cross-sectional study was conducted at a geriatric out-patient clinic in Hamilton, Canada. A research assistant conducted all frailty assessments. Patients were classified as non-frail, pre-frail or frail according to Fried’s phenotype method and the SPPB. Agreement among methods is reported using the Cohen kappa statistic (standard error). Feasibility data included the percent of eligible participants agreeing to attempt the frailty assessments (criterion for feasibility: ≥90% of patients agreeing to the frailty assessment), equipment required, and safety considerations. A p-value of <0.05 is considered significant.

Results

A total of 110 participants (92%) and 109 participants (91%) agreed to attempt Fried’s phenotype method and SPPB, respectively. No adverse events occurred during any assessments. According to Fried’s phenotype method, the prevalence of frailty and pre-frailty was 35% and 56%, respectively, and according to the SPPB, the prevalence of frailty and pre-frailty was 50% and 35%, respectively. There was fair to moderate agreement between methods for determining which participants were frail (0.488 [0.082], p < 0.001) and pre-frail (0.272 [0.084], p = 0.002).

Conclusions

Frailty and pre-frailty are common in this geriatric outpatient population, and there is fair to moderate agreement between Fried’s phenotype method and the SPPB. Over 90% of the patients who were eligible for the study agreed to attempt the frailty assessments, demonstrating that according to our feasibility criteria, frailty can be assessed in this patient population. Assessing frailty may help clinicians identify high-risk patients and tailor interventions based on baseline frailty characteristics.

Vitamin D: Musculoskeletal health

Perhaps the role of Vitamin D supplementation has been most exhaustively studied in calcium absorption, skeletal wellbeing, muscular potency, balance and risk of falling. Nonetheless, new data has emerged and the recent research on sarcopenia makes the topic increasingly interesting. Given the socioeconomic burden of the musculoskeletal consequences of hypovitaminosis D it is vital to keep abreast with the latest literature in the field. The recommended Vitamin D supplementation dose should suffice to increase the serum 25 hydroxyvitamin D level to 30 ng/mL (75 nmol/L) and this level should be optimally maintained with a maintenance dose, particularly for those diagnosed with osteoporosis.

Health promotion interventions for community-dwelling older people with mild or pre-frailty: a systematic review and meta-analysis

Background

Mild or pre-frailty is common and associated with increased risks of hospitalisation, functional decline, moves to long-term care, and death. Little is known about the effectiveness of health promotion in reducing these risks. This systematic review aimed to synthesise randomised controlled trials (RCTs) evaluating home and community-based health promotion interventions for older people with mild/pre-frailty.

Methods

We searched 20 bibliographic databases and 3 trials registers (January 1990 – May 2016) using mild/pre-frailty and associated terms. We included randomised controlled and crossover trials of health promotion interventions for community-dwelling older people (65+ years) with mild/pre-frailty and excluded studies focussing on populations in hospital, long term care facilities or with a specific condition. Risk of bias was assessed by two reviewers using the Cochrane Risk of Bias tool. We pooled study results using standardised mean differences (SMD) where possible and used narrative synthesis where insufficient outcome data were available.

Results

We included 10 articles reporting on seven trials (total n = 506 participants) and included five trials in a meta-analysis. Studies were predominantly small, of limited quality and six studies tested group exercise alone. One study additionally investigated a nutrition and exercise intervention and one evaluated telemonitoring. Interventions of exercise in groups showed mixed effects on functioning (no effects on self-reported functioning SMD 0.19 (95% CI -0.57 to 0.95) n = 3 studies; positive effects on performance-based functioning SMD 0.37 (95% CI 0.07 to 0.68) n = 3 studies). No studies assessed moves to long-term care or hospitalisations.

Conclusions

Currently the evidence base is of insufficient size, quality and breadth to recommend specific health promotion interventions for older people with mild or pre- frailty. High quality studies of rigorously developed interventions are needed.
