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

Economic burden of frailty in older adults accessing community-based aged care services in Australia

AIM

To explore the utilization of permanent residential aged care (PRAC), healthcare costs, and mortality for frail compared with non-frail individuals following their first assessment by an aged care assessment team (ACAT) for a government-funded home care package.

METHODS

The study involved people aged 65 years and over who completed their first ACAT assessment in 2013 and were followed for up to 36 months. Frail and non-frail study participants were matched through caliper matching without replacement to adjust for potential unobserved confounders. Poisson regression estimated the impact of frailty on PRAC admission and mortality rates. Healthcare costs, encompassing hospital admissions, emergency department presentations, primary care consultations, and pharmaceutical use, from ACAT assessment to end of follow-up, PRAC entry or death were summarized monthly by frailty status.

RESULTS

13 315 non-frail controls were matched with up to three frail individuals (52 678 total). Frail individuals experienced higher mortality (incidence rate ratio [IRR] = 1.76; 95% confidence interval [CI] 1.70-1.83) and greater likelihood of entering PRAC (IRR = 1.73; 95% CI 1.67-1.79) compared with non-frail individuals. Total healthcare costs over the 3-year post-assessment period for 39 363 frail individuals were $1 277 659 900, compared with expected costs of $885 322 522 had they not been frail. The primary contributor to the mean monthly excess cost per frail individual (mean = $457, SD = 3192) was hospital admissions ($345; 75%).

CONCLUSIONS

Frailty is associated with higher rates of mortality and of entering PRAC, and excess costs of frailty are substantial and sustained over time. These findings emphasize the potential economic value of providing home care for older people before they become frail. Geriatr Gerontol Int 2024; ••: ••-••.

Profiles of physical frailty, social frailty, and cognitive impairment among older adults in rural areas of China: a latent profile analysis

Background

As China rapidly ages, it has now become a deeply aging society with the largest number of older individuals in the world. The issue is particularly severe in rural areas. With the aging population growing and the older population expanding, health problems are becoming more prevalent among older individuals, particularly frailty and cognitive impairments. This study aimed to identify the profiles of physical frailty, social frailty, and cognitive impairment among older adults and explore the influencing factors.

Methods

In this cross-sectional study, participants were recruited from six villages in four cities in Shandong Province, China from July to October 2023 through cluster random sampling. Latent profile analysis was used to determine the profiles of physical frailty, social frailty, and cognitive impairment. Chi-square tests and Mann-Whitney U tests were used for univariate analysis, while binary logistic regression was used to analyze the related factors.

Results

Seven hundred and sixty-nine older adult care in rural areas showed two profiles: the "high cognitive function and low frailty" group (73.7%, n = 567) and the "low cognitive function and high frailty" group (26.3%, n = 202). A binary logistic regression found that older people were more likely to be aged 80 or older (OR = 2.253, p = 0.029), have a low income level (OR = 1.051, p = 0.007), have one or two (OR = 2.287, p = 0.004), or more than three chronic diseases (OR = 3.092, p = 0.002), and report moderate (OR = 3.406, p = 0.024) or poor health status (OR = 9.085, p < 0.001) in the "low cognitive function and high frailty" group. Meanwhile, older adults who have completed high school (OR = 0.428, p = 0.005) or junior college and above (OR = 0.208, p = 0.009), and engage in adequate physical activity (OR = 0.319, p < 0.001) were more likely to be in the "high cognitive function and low frailty" group.

Conclusion

In the future, medical professors should increasingly prioritize promptly identifying and intervening in cognitive decline and frailty status in older individuals without delay.

Combating Barriers to the Development of a Patient-Oriented Frailty Website

Unlabelled

This viewpoint article, which represents the opinions of the authors, discusses the barriers to developing a patient-oriented frailty website and potential solutions. A patient-oriented frailty website is a health resource where community-dwelling older adults can navigate to and answer a series of health-related questions to receive a frailty score and health summary. This information could then be shared with health care professionals to help with the understanding of health status prior to acute illness, as well as to screen and identify older adult individuals for frailty. Our viewpoints were drawn from 2 discussion sessions that included caregivers and care providers, as well as community-dwelling older adults. We found that barriers to a patient-oriented frailty website include, but are not limited to, its inherent restrictiveness to frail persons, concerns over data privacy, time commitment worries, and the need for health and lifestyle resources in addition to an assessment summary. For each barrier, we discuss potential solutions and caveats to those solutions, including assistance from caregivers, hosting the website on a trusted source, reducing the number of health questions that need to be answered, and providing resources tailored to each users' responses, respectively. In addition to screening and identifying frail older adults, a patient-oriented frailty website will help promote healthy aging in nonfrail adults, encourage aging in place, support real-time monitoring, and enable personalized and preventative care.

What do primary care providers want to know when caring for patients living with frailty? An analysis of eConsult communications between primary care providers and specialists

BACKGROUND

Frailty is a complex condition that primary care providers (PCPs) are managing in increasing numbers, yet there is no clear guidance or training for frailty care.

OBJECTIVES

The present study examined eConsult questions PCPs asked specialists about patients with frailty, the specialists' responses, and the impact of eConsult on the care of these patients.

DESIGN

Cross-sectional observational study.

SETTING

ChamplainBASE™ eConsult located in Eastern Ontario, Canada.

PARTICIPANTS

Sixty one eConsult cases closed by PCPs in 2019 that use the terms "frail" or "frailty" to describe patients 65 years of age or older.

MEASUREMENTS

The Taxonomy of Generic Clinical Questions (TGCQ) was used to classify PCP questions and the International Classification for Primary Care 3 (ICPC-3) was used to classify the clinical content of each eConsult. The impact of eConsult on patient care was measured by PCP responses to a mandatory survey.

RESULTS

PCPs most frequently directed their questions to cardiology (n = 7; 11%), gastroenterology (n = 7; 11%), and endocrinology (n = 6; 10%). Specialist answers most often pertained to medications (n = 63, 46%), recommendations for clinical investigation (n = 24, 17%), and diagnoses (n = 22, 16%). Specialist responses resulted in PCPs avoiding referral in 57% (n = 35) of cases whereas referrals were still required in 15% (n = 9) of cases. Specialists responded to eConsults in a median 1.11 days (IQR = 0.3-4.7), and 95% (n = 58) of cases received a response within 7 days. Specialists recorded a median of 15 min to respond (IQR = 10-20), with a median cost of $50.00 CAD (IQR = 33.33 - 66.66) per eConsult.

CONCLUSIONS

Through the analysis of questions and responses submitted to eConsult, this study provides novel information on PCP knowledge gaps and approaches to care for patients living with frailty. Furthermore, these analyses provide evidence that eConsult is a feasible and valuable tool for improving care for patients with frailty in primary care settings.

Clinical practice guidelines for frailty vary in quality but guide primary health care: a systematic review

OBJECTIVES

To appraise the methodological quality, clinical applicability, and reporting quality of clinical practice guidelines (CPGs) for frailty in primary care and identify research gaps using evidence mapping.

STUDY DESIGN AND SETTING

We conducted a systematic literature search in PubMed, Web of Science, Embase, CINAHL, guideline databases, and frailty or geriatric society websites. Appraisal of Guidelines Research and Evaluation II, AGREE-Recommendations Excellence, and Reporting Items for Practice Guidelines in Healthcare checklist were used to evaluate overall quality for frailty CPGs as "high", "medium", or "low" quality. We used bubble plots to show recommendations in CPGs.

RESULTS

Twelve CPGs were identified. According to the overall quality evaluation, five CPGs were considered as high quality, six as medium quality, and one as low quality. The recommendations in CPGs were generally consistent and mainly focused on frailty prevention, identification, multidisciplinary, nonpharmacological, and other treatments. However, evidence was lacking in some areas, such as effective prevention strategies and implementation of recommendations.

CONCLUSION

The frailty CPGs vary in quality but have consistent recommendations that can guide clinical practice in primary care. This could point the way for future research to address existing gaps and facilitate the development of trustworthy CPGs for frailty.

Frailty in Patients with Chronic Graft-versus-Host Disease

Frailty is an increasingly recognized clinical diagnosis associated with high risk of disability and mortality. Frailty in patients after hematopoietic cell transplantation (HCT) is associated with increased nonrelapse mortality (NRM) and decreased overall survival (OS). Frailty has not been studied extensively in patients with chronic graft-versus-host disease (cGVHD). The objectives of the present study were to assess the prevalence and clinical correlates of frailty and the association of frailty with NRM and OS in patients enrolled in the Chronic GVHD Consortium. Patients were characterized as frail if they met the Fried definition of ≥3 of the following criteria at enrollment: unintentional weight loss, exhaustion, slow walking speed, low physical activity, and weakness. Frailty was assessed retrospectively using surrogate measures for the 5 domains of frailty. Frailty, cGVHD organ scores, and patient-reported outcomes were measured at the time of enrollment. The study included 399 patients from 9 centers in the United States, with 32% characterized as frail and 68% as not frail. The median duration of follow-up from enrollment was 9 years (interquartile range, 7 to 11 years). Frail patients were more likely to be older (P = .004), to have a lower Karnofsky Performance Status (P < .001), to have severe cGVHD (P < .001), and to have gastrointestinal (P < .001), liver (P = .04), or lung cGVHD (P = .002). In a multivariable analysis, older age, increased cGVHD global severity, and thrombocytopenia were statistically significantly associated with frailty when cGVHD organ involvement was excluded. A separate analysis excluding cGVHD severity and including organ involvement showed that lung and liver cGVHD and older age were associated with frailty. Neither corticosteroid use at the time of enrollment nor the maximum recorded dose of corticosteroids before enrollment was associated with frailty. Frail patients had higher NRM than nonfrail patients (P < .001), with a 10-year cumulative incidence of 41% (95% confidence interval [CI], 32% to 49%) versus 22% (95% CI, 17% to 28%). Reciprocally, frailty also was associated with a significantly lower OS (P < .001), with a 10-year OS of 43% (95% CI, 35% to 53%) in frail patients versus 63% (95% CI, 57% to 69%) in nonfrail patients. In multivariable analysis that included the individual domains of frailty, weakness, low physical activity, and slow walking speed were associated with survival. Frail patients also had worse scores on various measures of patient-reported outcomes, including the Short Form (SF)-36, the Lee Symptom Scale, and the trial outcome of the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation (FACT-BMT) index score. Frail patients with cGVHD have significantly worse outcomes than nonfrail patients. Such clinical features as older age and lung and liver cGVHD are associated with frailty. Earlier clinical recognition of frailty in patients with cGVHD may prompt interventions to counteract frailty that could be beneficial for this population.

Potential Factors Influencing Adoption of a Primary Care Pathway to Prevent Functional Decline in Older Adults

Introduction

To help recognize and care for community-dwelling older adults living with frailty, we plan to implement a primary care pathway consisting of frailty screening, shared decision-making to select a preventive intervention, and facilitated referral to community-based services. In this study, we examined the potential factors influencing adoption of this pathway.

Methods

In this qualitative, descriptive study, we conducted semi-structured interviews and focus groups with patients aged 70 years and older, health professionals (HPs), and managers from four primary care practices in the province of Quebec, representatives of community-based services and geriatric clinics located near the practices. Two researchers conducted an inductive/deductive thematic analysis, by first drawing on the Consolidated Framework for Implementation Research and then adding emergent subthemes.

Results

We recruited 28 patients, 29 HPs, and 8 managers from four primary care practices, 16 representatives from community-based services, and 10 representatives from geriatric clinics. Participants identified several factors that could influence adoption of the pathway: the availability of electronic and printed versions of the decision aids; the complexity of including a screening form in the electronic health record; public policies that limit the capacity of community-based services; HPs' positive attitudes toward shared decision-making and their work overload; and lack of funding.

Conclusions

These findings will inform the implementation of the care pathway, so that it meets the needs of key stakeholders and can be scaled up.

A global perspective on risk factors for frailty in community-dwelling older adults: A systematic review and meta-analysis

BACKGROUND

Frailty has become an important determinant of a series of adverse health outcomes. We explored the risk factors for frailty in older adults in the community from a global perspective and explore whether there are ethnic differences in these risk factors.

METHODS

The systematic review and meta-analysis (PROSPERO registration number: CRD42022323342) was searched using six electronic databases, including PubMed, Embase, the Cochrane Library, Web of Science, PsycINFO (EBSCO) and CINAHL (EBSCO) from inception to October 2021. We assessed study eligibility by inclusion and excluded criteria. Cohort studies included were assessed according to the Newcastle-Ottawa Scale. Cross-sectional studies were assessed by the bias risk evaluation standard recommended by the Agency for Health care Research and Quality. The results were reported by a narrative synthesis and pooled analyses. Statistical analyses were performed in Review Manager 5.3 software.

RESULTS

We reviewed 10870 studies, and 62 studies were included. The results showed a significant association between multidomain risk factors and the frailty of global older adults, including demographic factors, health-related factors, and physical factors. Marital status, depression, risk of malnutrition, history of falls and disease-related symptoms are also risk factors for frailty among older people in Asia.

CONCLUSION

Multiple domain factors were associated with frailty among older people around the world. Compared with the rest of the world, Asian populations are exposed to more risk factors for frailty. Therefore, health care providers should consider the characteristics of risk factors for frailty in this region when formulating intervention measures related to frailty.

Impact of frailty, mild cognitive impairment and cognitive frailty on adverse health outcomes among community-dwelling older adults: A systematic review and meta-analysis

Aims

This study analyzes the impact of frailty, mild cognitive impairment, and cognitive frailty on adverse outcomes in community-dwelling older adults.

Methods

This systematic review and meta-analysis were conducted using the PRISMA guidelines and MOOSE statement. We developed a specific search strategy for each electronic database and searched PubMed, Web of Science, MEDLINE, and Embase from initial records to July 2021. The studies on adverse outcomes of frailty, pre-frailty, mild cognitive impairment, and mild cognitive impairment with pre-frailty and cognitive frailty were included. Two researchers independently extracted data based on a spreadsheet and assessed the risk of bias. The primary outcomes were mortality, dementia, disability, and hospitalization. The second outcome included quality of life and falls. All analysis was conducted by using Review Manager (RevMan) 5.3 software.

Results

A total of 22 cohort studies (71,544 older adults with mean age ranging from 65.1 to 93.6 years) were included with a low risk of bias and high methodological quality with a NOS score ≥7. Compared to robust elders, individuals identified as frailty were associated with a higher risk of mortality (RR = 2.11, 95% CI: 1.57–2.83) and disability (RR = 5.91, 95% CI: 2.37–14.74). Mild cognitive impairment with pre-frailty was associated with mortality (RR = 1.74, 95% CI: 1.48–2.05) and dementia (RR = 4.15, 95% CI: 1.87–9.20). Pre-frailty was associated with a higher risk of mortality (RR = 1.29, 95% CI: 1.11–1.50). Cognitive frailty was associated with higher risk of incident mortality (RR = 2.41, 95% CI: 1.97–2.94), dementia (RR = 3.67, 95% CI: 2.81–4.78), disability (RR = 11.32, 95% CI: 4.14–30.97), and hospitalization (RR = 2.30, 95% CI: 1.60–3.32), as well as poor quality of life.

Conclusion

Cognitive frailty could be a comprehensive psychosomatic predictor for adverse outcomes among older people. Interactions between frailty, mild cognitive impairment, and cognitive frailty on adverse outcomes must be further explored.

Practitioner perceptions of the feasibility of common frailty screening instruments within general practice settings: a mixed methods study

BACKGROUND

Frailty is a highly prevalent clinical syndrome increasing older people's vulnerability to risk of adverse outcomes. Better frailty identification through expanded screening implementation has been advocated within general practice settings, both internationally and within Australia. However, little is known about practitioner perceptions of the feasibility of specific instruments, and the underlying motivations behind those perceptions. Consequently, the purpose of this study was to explore the attitudes and perceptions of a convenience and volunteer sample of Australian general practitioners (GPs) and practice nurses (PNs) towards common frailty screening instruments.

METHODS

The feasibility of several frailty screening instruments (PRISMA-7 [P7], Edmonton Frail Scale [EFS], FRAIL Questionnaire [FQ], Gait Speed Test [GST], Groningen Frailty Indicator [GFI], Kihon Checklist [KC] and Timed Up and Go [TUG]) to 43 Australian GPs and PNs was assessed. The study adopted a concurrent embedded mixed-methods design incorporating quantitative (ranking exercise) and qualitative (content analysis) data collection integrated during the analysis phase.

RESULTS

Practitioners assessed multi-dimensional instruments (EFS, GFI, KC) as having relatively higher clinical utility, better integration into existing assessment processes and stronger links to intervention over uni-dimensional (GST, TUG) and simple (FQ, P7) instruments.

CONCLUSIONS

While existing frailty screening instruments show promise as an initial step in supporting better care for older people, all the included instruments were associated with perceived advantages and disadvantages. Ultimately, clinicians will need to weigh several factors in their selection of the optimal screening instrument. Further translational research, with a focus on contextual fit, is needed to support clinical decision-making on the selection of instruments for frailty screening.

Identifying Frail Patients by Using Electronic Health Records in Primary Care: Current Status and Future Directions

With the rapidly aging population, frailty, characterized by an increased risk of adverse outcomes, has become a major public health problem globally. Several frailty guidelines or consensuses recommend screening for frailty, especially in primary care settings. However, most of the frailty assessment tools are based on questionnaires or physical examinations, adding to the clinical workload, which is the major obstacle to converting frailty research into clinical practice. Medical data naturally generated by routine clinical work containing frailty indicators are stored in electronic health records (EHRs) (also called electronic health record (EHR) data), which provide resources and possibilities for frailty assessment. We reviewed several frailty assessment tools based on primary care EHRs and summarized the features and novel usage of these tools, as well as challenges and trends. Further research is needed to develop and validate frailty assessment tools based on EHRs in primary care in other parts of the world.

Rural Family Caregiving: A Closer Look at the Impacts of Health, Care Work, Financial Distress, and Social Loneliness on Anxiety

Even before the COVID-19 pandemic, earlier acute care patient discharges, restricted admissions to long-term care, and reduced home care services increased the amount and complexity of family caregivers’ care work. However, much less is known about rural caregivers’ experiences. Thus, our aim in this sequential mixed-methods study was to understand how COVID-19 affected rural family caregivers. Thematically analyzed interviews and linear regression on survey data were used to understand family caregiver stress. Fourteen rural caregivers participated in interviews. They acknowledged that they benefitted from the circle of support in rural communities; however, they all reported having to cope with fewer healthcare and social services. 126 rural caregivers participated in the online survey. About a third (31%) of these caregivers had moderate frailty, indicating that they could benefit from support to improve their health. In linear regression, frailty, social loneliness, financial hardship, and younger age were associated with caregiver anxiety. Contrary to the qualitative reports that people in rural communities are supportive, over two-thirds of the rural caregivers completing the survey were socially lonely. Rural family caregivers are vulnerable to anxiety and social loneliness due to the nature of caregiving and the lack of healthcare and social service supports in rural areas. Primary healthcare and home care teams are well-positioned to assess caregivers’ health and care situation as well as to signpost them to needed supports that are available in their areas.

[Frailty in primary care: Diagnosis and multidisciplinary management]

El envejecimiento poblacional se asocia a un mayor uso de recursos sociales sanitarios, asociados a la mayor morbimortalidad y discapacidad de este grupo etario. La fragilidad es un síndrome geriátrico previo a la aparición de la dependencia funcional, que permite la identificación de individuos de mayor riesgo de dependencia, institucionalización, efectos adversos de fármacos, mortalidad y otros eventos negativos de salud. Este síndrome es potencialmente reversible con una intervención multicomponente. La atención primaria de salud es el lugar preferente para el diagnóstico y seguimiento de la fragilidad, a través de escalas como la FRAIL scale, el fenotipo de Fried o modelos de acumulación de déficits. Para el seguimiento se precisa la intervención multidimensional y coordinada de diferentes profesionales sanitarios y sociales, con la implicación del paciente y su familia. Se debe fomentar la investigación para determinar las intervenciones más eficaces y los cursos clínicos más frecuentes.

Perspectives of older adults, caregivers, healthcare providers on frailty screening in primary care: a systematic review and qualitative meta-synthesis

Background

Screening is often recommended as a first step in frailty management. Many guidelines call to implicate frailty screening into practice in the primary care setting. However, few countries or organizations implement it. Understanding and clarifying the stakeholders’ views and issues faced by the implementation is essential to the successful implementation of frailty screening. However, the systematic review on stakeholders’ views of frailty screening in primary care is decidedly limited. Our objective was to explore the perspective of older adults, caregivers, and healthcare providers on frailty screening and determine the enablers and barriers to implementing frailty screening in primary care.

Methods

A systematic search of six databases and other resources was conducted following JBI’s three-step search strategy. The search resulted in 7362 articles, of which 97 were identified for further assessment according to the inclusion criteria. After the full-text screening, quality assessment and data extraction were carried out using the tools from Joanna Briggs Institute (JBI). Moreover, reviewers used the approach of meta-aggregative of JBI to analyze data and synthesis the findings.

Results

Six studies were included. A total of 63 findings were aggregated into 12 categories and then further grouped into three synthesized findings:1) capacity of healthcare providers and older adults; 2) opportunity in the implementation of frailty screening; 3) motivation in the implementation of frailty screening. These themes can help identify what influences the implementation of screening from the perspective of stakeholders.

Conclusions

This meta-synthesis provides evidence on the barriers and enablers of frailty screening in primary care, from the aspects of psychological, physical, social, material, etc. However, stakeholder perspectives of frailty screening have not been adequately studied. More research and efforts are needed to explore the influencing factors and address the existing barriers.

Self-reported Frailty Screening Tools: Comparing Construct Validity of the Frailty Phenotype Questionnaire and FRAIL

OBJECTIVES

We examined the construct validity of 2 self-reported frailty questionnaires, the Frailty Phenotype Questionnaire (FPQ) and FRAIL, against the Cardiovascular Health Study frailty phenotype (CHS-FP).

DESIGN

Cross-sectional data analysis of longitudinal prospective cohort study.

SETTINGS AND PARTICIPANTS

We included data from 230 older adults (mean age: 67.2 ± 7.4 years) from the "Longitudinal Assessment of Biomarkers for characterization of early Sarcopenia and Osteosarcopenic Obesity in predicting frailty and functional decline in community-dwelling Asian older adults Study" (GeriLABS 2) recruited between December 2017 and March 2019.

METHODS

We compared area under receiver operating characteristic curves (AUC), agreement, correlation, and predictive validity against outcome measures (Short Physical Performance Battery, 5 times repeat chair stand [RCS-5], Frenchay activities index, International Physical Activity Questionnaire, life-space assessment, Social Functioning Scale 8 [SFS-8], EuroQol-5 dimensions [utility value]) using logistic regression adjusted for age, gender, and vascular risk factors. We examined concurrent validity across robust versus prefrail/frail for inflammatory blood biomarkers (tumor necrosis factor receptor 1 and C-reactive protein [CRP]) and dual-energy x-ray absorptiometry body composition (bone mineral density (BMD); appendicular lean mass index [ALMI], and fat mass index [FMI]).

RESULTS

Prevalence of prefrail/frail was 25.7%, 14.8%, and 48.3% for FPQ, FRAIL, and CHS-FP, respectively. Compared with FRAIL, FPQ had better diagnostic performance (AUC = 0.617 vs 0.531, P = .002; sensitivity = 37.8% vs 18.0%; specificity = 85.6% vs 88.2%) and agreement (AC1-Stat = 0.303 vs 0.197). FPQ showed good predictive validity (RCS-5: odds ratio [OR] 2.38; 95% CI: 1.17-4.86; International Physical Activity Questionnaire: OR 3.62; 95% CI:1.78-7.34; SFS-8: OR 2.11; 95% CI: 1.64-5.89 vs FRAIL: all P > .05). Only FRAIL showed concurrent validity for CRP, compared with both FPQ and FRAIL for TNF-R1. FRAIL showed better concurrent validity for BMD, FMI, and possibly ALMI, unlike FPQ (all P > .05).

CONCLUSIONS AND IMPLICATIONS

Our results support complementary validity of FPQ and FRAIL in independent community-dwelling older adults. FPQ has increased case detection sensitivity with good predictive validity, whereas FRAIL demonstrates concurrent validity for inflammation and body composition. With better diagnostic performance and validity for blood biomarkers and clinical outcomes, FPQ has utility for early frailty detection in the community setting.

Influence of frailty and its interaction with comorbidity on outcomes among total joint replacement

BACKGROUND

Patients with frailty get more and more attention in clinical practice. Yet, no large-scale studies have explored the impact of frailty on the perioperative acute medical and surgical complications following TJA. what is more, comorbid diseases may lead, at least additively, to the development of frailty. There also no studies to find the possible interaction between comorbidity and frailty on the postoperative complications after TJA.

METHODS

Discharge data of 2,029,843 patients who underwent TJA from 2005 to 2014 from the National Inpatient Sample (NIS) database, which was analyzed using cross-tabulations and multivariate regression modeling. Frailty was defined based on frailty-defining diagnosis clusters from frailty-defining diagnosis indicator of Johns Hopkins Adjusted Clinical Groups.

RESULTS

Among patients who underwent total joint replacement surgeries, 50,385 (2.5%) were identified as frail. Frailty is highly associated with old age, especially for those over the age of 80, meanwhile females and black races have a high Charlson comorbidity index (CCI) of ≥ 3, together with emergency/urgent admission and teaching hospital. While comorbidity is associated with greater odds of acute medical complications, and frailty has a better predictive effect on in-hospital deaths, acute surgical complications. Furthermore, frailty did not show an enhancement in the predictive power of the Charlson comorbidity score for postoperative complications or in-hospital deaths but postoperative LOS and hospitalization costs.

CONCLUSION

Frailty can be used to independently predicted postoperative surgical and medical complications, which also has a synergistic interaction with comorbidity for patients who are preparing to undergo TJA.

Frailty Among Older Individuals with and without COPD: A Cohort Study of Prevalence and Association with Adverse Outcomes

Rationale

Frailty prevalence estimates among individuals with COPD have varied widely, and few studies have investigated relationships between frailty and adverse outcomes in a COPD population.

Objective(s)

Describe frailty prevalence among individuals with and without COPD and examine associations between frailty and mortality and other adverse outcomes in the next two years.

Methods

This was an observational cohort study using Health and Retirement Study data (2006–2018) of community living individuals ages 50–64 and ≥65 with and without COPD (non-COPD). Frailty (Fried phenotype [5 items], and a modified Frailty Index-Comprehensive Geriatric Assessment [Enhanced FI-CGA] [37 items], and debility (modified BODE Index [4 items]) were assessed. Two-year post-assessment outcomes (mortality, ≥1 inpatient stay, home health and skilled nursing facility (SNF) use) were reviewed in a population matched 3:1 (non-COPD: COPD) on age, sex, race, and year using univariate and multivariate logistic regression (adjusted for morbidities). Area-under-the-curve (AUC) was used to evaluate regressions.

Results

The study included 18,979 survey observations for age 50–64, and 24,162 age ≥65; 7.8% and 12.0% respectively reporting a diagnosis of COPD. Fried phenotype frailty prevalence for age ≥65 was 23.1% (COPD) and 9.4% (non-COPD), and for the Enhanced FI-CGA, 45.9% (COPD) and 22.4% (non-COPD). Two-year mortality for COPD was more than double non-COPD for age 50–64 (95% CI: 3.8–5.9% vs 0.7–1.3%) and age ≥65 (95% CI: 11.9–14.3% vs 5.6–6.6%). Inpatient utilization, home health care use, or at least temporary SNF placement were also more frequent for COPD. Measures were predictive of adverse outcomes. In adjusted models, the Fried phenotype and modified BODE score performed similarly, and both performed better than the Enhanced FI-CGA index. AUC values were higher for morality regressions.

Conclusion

Frailty prevalence among individuals with COPD in this national survey is substantially greater than without COPD, even at pre-retirement (50–64 years). These measures identify patients with increased risk of poor outcomes.

Facilitating the planning and evaluation of narrative intervention reviews: Systematic Transparency Assessment in Intervention Reviews (STAIR)

Narrative reviews offer a flexible way to report intervention results and comprise the majority of reviews published in top medical journals. However variations in their transparency pose evaluation challenges, compromising their value and potentially resulting in research wastage. Calls have been made to reduce the number of narrative reviews published. Others argue narrative reviews provide an important platform and should even be placed on an equal footing to systematic reviews. We believe narrative intervention reviews can provide a vital perspective when transparent, and thus support Systematic Transparency Assessment in Intervention Reviews (STAIR). This research evaluates the transparency of 172 health-related narrative and literature reviews (K = 172), by assessing how they communicate information about the interventions they review. Eight points supporting transparency, relating to sample sizes, traceability, article numbers, and references, were assessed. Half of the reviews reported on at least four of the eight points, but 24% reported on none. Only 56% of the reviews clearly communicated full references. The STAIR* (Sample sizes, Traceability, Article numbers, Intervention numbers, References*) checklist comprises five sections, and nine points. It is proposed as a convenient tool to address STAIR and complement existing review guidelines to assist authors in planning, reviewers in evaluating, and scholars in utilising narrative reviews. The objectives of STAIR* are to: 1) encourage narrative review transparency and readability, 2) facilitate the incorporation of narrative reviews results into other research; and 3) enrich narrative review methodology with a checklist to guide, and evaluate, intervention reviews.

Perspectives on frailty screening, management and its implementation among acute care providers in Singapore: a qualitative study

BACKGROUND

COVID-19 pandemic has reminded how older adults with frailty are particularly exposed to adverse outcomes. In the acute care setting, consideration of evidence-based practice related to frailty screening and management is needed to improve the care provided to aging populations. It is important to assess for frailty in acute care so as to establish treatment priorities and goals for the individual. Our study explored understanding on frailty and practice of frailty screening among different acute care professionals in Singapore, and identify barriers and facilitators concerning frailty screening and its implementation.

METHODS

A qualitative study using focus group discussion among nurses and individual interviews among physicians from four departments (Accident & Emergency, Anesthesia, General Surgery, Orthopedics) in three acute hospitals from the three public health clusters in Singapore. Participants were recruited through purposive sampling of specific clinicians seeing a high proportion of older patients at the hospitals. Thematic analysis of the data was performed using NVIVO 12.0.

RESULTS

Frailty was mainly but inadequately understood as a physical and age-related concept. Screening for frailty in acute care was considered important to identify high risk patients, to implement targeted treatment and care, and to support decision making and prognosis estimation. Specific issues related to screening, management and implementation were identified: cooperation from patient/caregivers, acceptance from healthcare workers/hospital managers, need for dedicated resources, guidelines for follow-up management and consensus on the scope of measurement for different specialties.

CONCLUSION

Our findings indicated the need for 1) frailty-related education program for patients/care givers and stakeholders 2) inter-professional collaboration to develop integrated approach for screening and management of hospital patients with frailty and 3) hospital-wide consensus to adopt a common frailty screening tool.

Explaining the association between frailty and mortality in older adults: The mediating role of lifestyle, social, psychological, cognitive, and physical factors

•

Frailty in older adults is associated with adverse outcomes such as mortality.

•

Not much is known about underlying pathways of the frailty-mortality association.

•

We assessed the mediating role of a wide range of factors.

•

In both men and women, only polypharmacy was identified as explanatory factor.

•

Targeting polypharmacy in frail older adults could reduce their risk of mortality.

Frailty is associated with a higher risk of mortality, but not much is known about underlying pathways of the frailty-mortality association. In this study, we explore a wide range of possible mediators of the relation between frailty and mortality. Data were used from the Longitudinal Aging Study Amsterdam (LASA). We included 1477 older adults aged 65 years and over who participated in the study in 2008–2009 and linked their data to register data on mortality up to 2015. We examined a range of lifestyle, social, psychological, cognitive, and physical factors as potential mediators. All analyses were stratified by sex. We used causal mediation analyses to estimate the indirect effects in single-mediator analyses. Statistically significant mediators were then included in multiple-mediator analyses to examine their combined effect. The results showed that older men (OR = 2.79, 95% CI = 1.23;6.34) and women (OR = 2.31, 95% CI = 1.24;4.30) with frailty had higher odds of being deceased 6 years later compared to those without frailty. In men, polypharmacy (indirect effect OR = 1.21, 95% CI = 1.03;1.50) was a statistically significant mediator in this association. In women, polypharmacy, self-rated health, and multimorbidity were statistically significant mediators in the single-mediator models, but only the indirect effect of polypharmacy remained in the multiple-mediator model (OR = 1.16, 95% CI = 1.03;1.38). In conclusion, of many factors that were considered, we identified polypharmacy as explanatory factor of the association between frailty and mortality in older men and women. This finding has important clinical implications, as it suggests that targeting polypharmacy in frail older adults could reduce their risk of mortality.

Predictive value of intrinsic capacity on adverse outcomes among community-dwelling older adults

OBJECTIVE

To examine the predictive value of intrinsic capacity on one-year incident adverse outcomes among community-dwelling older adults.

METHODS

A total of 756 community-dwelling older adults aged ≥ 60 years were followed up after 1 year. Intrinsic capacity was assessed using the revised integrated care for older people screening tool. Adverse outcomes included incident disability, recurrent falls, hospitalization, emergency department visits, and poor quality of life. Multivariate logistic regression models were performed to evaluate the predictive value of intrinsic capacity domains on adverse outcomes.

RESULTS

Cognitive decline, limited mobility, visual impairment and depressive symptoms predicted incident disability. Visual impairment predicted recurrent falls. Cognitive decline and limited mobility predicted emergency department visits. Limited mobility predicted poor quality of life.

DISCUSSION

Intrinsic capacity could predict incident adverse outcomes among community-dwelling older adults. Assessing intrinsic capacity would facilitate early identification of older adults at high risk of adverse outcomes and prompt targeted interventions.

The effectiveness of nutrition interventions in improving frailty and its associated constructs related to malnutrition and functional decline among community-dwelling older adults: A systematic review

BACKGROUND

The present study aimed to evaluate the effectiveness of nutrition interventions on frailty and factors related to frailty, including malnutrition, sarcopenia and functional ability, among community dwelling older adults. A secondary aim was to synthesise current clinical guidelines for the identification and management of frailty, and then identify whether they aligned with the findings of the literature review.

METHODS

A systematic literature review was undertaken using four electronic databases to identify randomised controlled clinical trials that assessed the effect of nutrition interventions on frailty and outcomes related to frailty in community-dwelling older adults (PROSPERO #CRD42017069094). The quality of the included studies was appraised. A rapid review was conducted using the Google Scholar database to identify existing clinical recommendations relating to the second aim.

RESULTS

The search strategy identified 13 studies. Multifactorial interventions with nutritional education and protein-energy supplementation improved frailty stratus and physical performance in 75% and 58% of studies, respectively. Weight and nutritional status improved in 80% of studies that used oral nutritional support. The recommended process for clinical management of frailty involves screening, followed by full assessment using validated instruments and the development of a comprehensive management plan with a multidisciplinary team.

CONCLUSIONS

Multifactorial interventions were found to be more effective than nutrition intervention alone for improving frailty and physical performance. Protein-energy supplementation tended to be effective only in malnourished older adults. The results were inconclusive for the use of micronutrient supplementation for frailty and outcomes related to frailty. Existing clinical guidelines are aligned with the evidence recommending comprehensive interventions to improve frailty.

Association Between Central and Peripheral Age-Related Hearing Loss and Different Frailty Phenotypes in an Older Population in Southern Italy

Importance

The association between age-related hearing loss (ARHL) and physical or cognitive frailty has been poorly explored. These associations could define new perspectives for delaying frailty-related processes in older age.

Objective

To examine whether peripheral ARHL and age-related central auditory processing disorder (CAPD) are independently associated with physical or cognitive frailty.

Design, Setting, and Participants

This cross-sectional study analyzed registry data from December 31, 2014, on 1929 older (≥65 years) participants of the Salus in Apulia Study (Southern Italy) who underwent audiologic, physical, and neuropsychological assessment. Data analysis was performed from December 12, 2019, to January 4, 2020.

Main Outcomes and Measures

Prevalence of peripheral ARHL in older individuals with physical and/or cognitive frailty and those without frailty assessed using the Fried criteria (physical) and the Mini-Mental State Examination (cognitive). Multivariable logistic regression models were used to assess associations of audiologic variables with frailty phenotype.

Results

Data from 1929 participants (mean [SD] age, 73.6 [6.3] years; 974 male [50.5%]) were eligible for the analyses. The prevalence of peripheral ARHL was higher in the physical frailty group (96 [26.6%]) than in the nonfrail group (329 [21.0%]) (difference, 5.61 percentage points; 95% CI, 0.63-10.59 percentage points) and in the cognitive frailty group (40 [38.8%]) than in the nonfrail group (385 [21.1%]) (difference, 17.75 percentage points; 95% CI, 8.2-27.3 percentage points). Age-related CAPD was more prevalent in the physical frailty group (62 [17.2%]) than in the nonfrail group (219 [14.0%]) (difference, 3.21 percentage points; 95% CI, -1.04 to 7.46 percentage points) and in the cognitive frailty group (28 [27.2%]) than in the nonfrail group (253 [13.9%]) (difference, 13.33 percentage points; 95% CI, 4.10-22.21 percentage points). In the multivariable models, age-related CAPD was associated with cognitive frailty in the fully adjusted model (odds ratio [OR], 1.889; 95% CI, 1.094-3.311). There was also an inverse association between the unitary increase in Synthetic Sentence Identification With the Ipsilateral Competitive Message scores, indicating a lower likelihood of this disorder, and cognitive frailty (OR, 0.989; 95% CI, 0.988-0.999). Peripheral ARHL was associated with cognitive frailty only in the partially adjusted model (OR, 1.725; 95% CI, 1.008-2.937).

Conclusions and Relevance

In this cross-sectional study of 1929 participants, age-related CAPD was independently associated with cognitive frailty. Whether the management of ARHL may help prevent the development of different frailty phenotypes or improve their clinical consequences should be addressed in longitudinal studies and, eventually, well-designed randomized clinical trials.

Association of frailty with health service utilisation and health care expenditure in sub-Saharan Africa: evidence from Côte d'Ivoire

Background

Frailty, a syndrome resulting in heightened risk of negative outcomes for older adults, is increasing across the globe. However, little is known about the health service impacts of frailty in low-income countries (LICs), and in particular, sub-Saharan Africa (SSA). This study explores the relationship between frailty and health service 1) utilisation and 2) expenditure within Côte d’Ivoire.

Methods

Participants aged 50 years and over participated in the Living Condition, Health and Resilience among the Elderly study. Frailty was assessed using a 30-item Frailty Index (FI). The association between frailty and self-reported health service utilisation was analysed for general practitioners (GPs), specialists, overnight hospitalisations, traditional practitioners and self-medication. Expenditure over the previous month included consulting, medications, hospitalisations and total expenditure.

Results

Among participants [n = 860, mean age (SD) = 61.8 (9.7) years, 42.9% female], 60.0% were frail, 22.8% pre-frail and 17.2% robust. The mean (SD) FI was 0.28 (0.17). Increased health service utilisation was associated with frailty for GP attendance, traditional practitioners and self-medication but not specialists or overnight hospitalisation. Pre-frailty and frailty were associated with increased total health service expenditure, with frailty also associated with aggregate consulting costs and medications.

Conclusions

Although frailty is associated with health service utilisation and expenditure in a variety of contexts, the study results suggest that such impacts may vary across the globe. The experience of frailty in LICs is likely to differ from that experienced elsewhere due to cultural traditions, attitudes to the health system, and accessibility, with more research needed.

Older Adults' Perceptions of Frailty Language: A Scoping Review

There is growing interest in conceptualizing and diagnosing frailty. Less is understood, however, about older adults' perceptions of the term "frail", and the implications of being classified as "frail". The purpose of this scoping review was to map the breadth of primary studies; and describe the meaning, perceptions, and perceived implications of frailty language amongst community-dwelling older adults. Eight studies were included in the review and three core themes were identified: (1) understanding frailty as inevitable age-related decline in multiple domains, (2) perceiving frailty as a generalizing label, and (3) perceiving impacts of language on health and health care utilization. Clinical practice recommendations for health care professionals working with individuals with frailty include: (1) maintaining a holistic view of frailty that extends beyond physical function to include psychosocial and environmental constructs, (2) using person-first language, and (3) using a strengths-based approach to discuss aspects of frailty.

A Contextual Analysis and Logic Model for Integrated Care for Frail Older Adults Living at Home: The INSPIRE Project

INTRODUCTION

Implementation science methods and a theory-driven approach can enhance the understanding of whether, how, and why integrated care for frail older adults is successful in practice. In this study, we aimed to perform a contextual analysis, develop a logic model, and select preliminary implementation strategies for an integrated care model in newly created information and advice centers for older adults in Canton Basel-Landschaft, Switzerland.

METHODS

We conducted a contextual analysis to determine factors which may influence the integrated care model and implementation strategies needed. A logic model depicting the overall program theory, including inputs, core components, outputs and outcomes, was designed using a deductive approach, and included stakeholders' feedback and preliminary implementation strategies.

RESULTS

Contextual factors were identified (e.g., lack of integrated care regulations, existing community services, and a care pathway needed). Core components of the care model include screening, referral, assessment, care plan creation and coordination, and follow-up. Outcomes included person-centred coordinated care experiences, hospitalization rate and symptom burden, among others. Implementation strategies (e.g., nurse training and co-developing educational materials) were proposed to facilitate care model adoption.

CONCLUSION

Contextual understanding and a clear logic model should enhance the potential for successful implementation of the integrated care model.

Care of frail and older adults: A content analysis of paramedic operational clinical practice guidelines

INTRODUCTION

Frailty rates are increasing with population ageing. In paramedicine, Clinical Practice Guidelines (CPGs) are essential documents that support decision making, yet little evidence exists regarding the support CPGs provide paramedics in the care of frail and older adults.

AIM

To investigate how CPGs support paramedics' care of frail and older adults.

METHODS

CPGs from nine Australasian paramedic services were collected in 2019. Content analysis was used to explore two hundred and thirty-seven individual CPGs for decision support information regarding frail and older adults.

RESULTS

Evidence-based content relating to older adults was sparse compared to paediatric content. Two overarching decision support domains were identified, patient assessment and management. Inconsistent age descriptors were widespread, particularly in pharmacological guidelines. Five service providers' CPGs contained validated assessment instruments for use with older adults.

CONCLUSION

Decision support documentation regarding frail and older adults varies across Australasian paramedic services. Frailty and older adult specific CPGs, and validated assessment instruments suitable to the paramedicine environment could improve paramedic decision making and minimise patient risk. A collaborative approach encompassing service providers and educational institutions is crucial to develop consistent, evidence-based CPGs relevant to older adults.

[Clinical importance of the detection of frailty]

Frailty ist ein multidimensionales geriatrisches Syndrom, das durch einen Verlust an individueller Reservekapazität und eine erhöhte Vulnerabilität gegenüber internen und externen Stressoren gekennzeichnet ist. Frailty ist mit einem erhöhten Risiko für Stürze und einen Autonomieverlust sowie mit einer erhöhten Mortalität verbunden. Die Identifikation von Personen, die eine Frailty aufweisen, kann ein umfangreiches geriatrisches Assessment triggern und gezielte Therapieangebote begründen. Darüber hinaus können durch die Erfassung von Frailty jene Patient*innen identifiziert werden, die ein erhöhtes Risiko für ungünstige Behandlungsverläufe haben. Für die Erfassung von Frailty gibt es eine unübersichtliche Zahl an Instrumenten, wobei nur eine eingeschränkte Auswahl dieser Instrumente in einer deutschen Version vorliegt. Die Wahl des Instruments sollte sich am klinischen Setting und den vorhandenen Ressourcen orientieren.

Commonly Used Screening Instruments to Identify Frailty Among Community-Dwelling Older People in a General Practice (Primary Care) Setting: A Study of Diagnostic Test Accuracy

BACKGROUND

Rapid frailty screening remains problematic in primary care. The diagnostic test accuracy (DTA) of several screening instruments has not been sufficiently established. We evaluated the DTA of several screening instruments against two reference standards: Fried's Frailty Phenotype [FP] and the Adelaide Frailty Index [AFI]), a self-reported questionnaire.

METHODS

DTA study within three general practices in South Australia. We randomly recruited 243 general practice patients aged 75+ years. Eligible participants were 75+ years, proficient in English and community-dwelling. We excluded those who were receiving palliative care, hospitalized or living in a residential care facility.We calculated sensitivity, specificity, predictive values, likelihood ratios, Youden Index and area under the curve (AUC) for: Edmonton Frail Scale [EFS], FRAIL Scale Questionnaire [FQ], Gait Speed Test [GST], Groningen Frailty Indicator [GFI], Kihon Checklist [KC], Polypharmacy [POLY], PRISMA-7 [P7], Reported Edmonton Frail Scale [REFS], Self-Rated Health [SRH] and Timed Up and Go [TUG]) against FP [3+ criteria] and AFI [>0.21].

RESULTS

We obtained valid data for 228 participants, with missing scores for index tests multiply imputed. Frailty prevalence was 17.5% frail, 56.6% prefrail [FP], and 48.7% frail, 29.0% prefrail [AFI]. Of the index tests KC (Se: 85.0% [70.2-94.3]; Sp: 73.4% [66.5-79.6]) and REFS (Se: 87.5% [73.2-95.8]; Sp: 75.5% [68.8-81.5]), both against FP, showed sufficient diagnostic accuracy according to our prespecified criteria.

CONCLUSIONS

Two screening instruments-the KC and REFS, show the most promise for wider implementation within general practice, enabling a personalized approach to care for older people with frailty.

Predictive performance of 7 frailty instruments for short-term disability, falls and hospitalization among Chinese community-dwelling older adults: A prospective cohort study

BACKGROUND

Frailty becomes a great challenge with population aging. The proactive identification of frailty is considered as a rational solution in the community. Previous studies found that frailty instruments had insufficient predictive accuracy for adverse outcomes, but they mainly focused on long-term outcomes and constructed frailty instruments based on available data not original forms. The predictive performance of original frailty instruments for short-term outcomes in community-dwelling older adults remains unknown.

OBJECTIVE

To examine the predictive performance of seven frailty instruments in their original forms for 1-year incident outcomes among community-dwelling older adults.

DESIGN

A prospective cohort study.

SETTINGS

A total of 22 communities were selected by a stratified sampling method from one Chinese city.

PARTICIPANTS

A total of 749 older adults aged ≥ 60 years (mean age of 69.2 years, 69.8% female) were followed up after 1 year.

METHODS

Baseline frailty was assessed by three purely physical dimensional instruments (i.e. Frailty Phenotype, the Study of Osteoporotic Fracture and FRAIL Scale) and four multidimensional instruments (i.e. Frailty Index, Groningen Frailty Indicator, Tilburg Frailty Indicator and Comprehensive Frailty Assessment Instrument), respectively. Outcomes included incident disability, falls, hospitalization and the combined outcome at 1-year follow-up. The receiver operating characteristic curves were plotted to assess the predictive performance of frailty instruments.

RESULTS

The areas under the curves of seven frailty instruments in predicting incident outcomes ranged from 0.55 [95% confidence interval (CI): 0.51-0.60] to 0.67 (95% CI: 0.61-0.72), with high specificity (72.3-99.2%) and low sensitivity (4.0-49.6%). Four multidimensional instruments had much higher sensitivity (20.9-49.6% versus 4.0-11.7%) than three purely physical dimensional instruments. Overall, the Frailty Index was more accurate than some instruments in predicting incident outcomes, while several self-report instruments had comparable predictive accuracy to the Frailty Index for all (FRAIL Scale) or some (Groningen Frailty Indicator and Tilburg Frailty Indicator) of the incident outcomes.

CONCLUSIONS

All frailty instruments have inadequate predictive accuracy for short-term outcomes among community-dwelling older adults. The Frailty Index roughly performs better but self-report instruments are comparable to the Frailty Index for all or some of the outcomes. An accurate frailty instrument needs to be developed, and the simple self-report instruments could be used temporarily as practical and efficient tools in primary care.

Comparing the Performance of Different Instruments for Diagnosing Frailty and Predicting Adverse Outcomes among Elderly Patients with Gastric Cancer

OBJECTIVES

To examine the diagnostic performance of the Tilburg Frailty Indicator (TFI), 11-factor modified frailty index (mFI-11), and 5-factor modified frailty index (mFI-5) for frailty defined by Frailty Phenotype (FP), as well as to compare the predictive ability of TFI, mFI-11, and mFI-5 for adverse outcomes in hospital among elderly patients undergoing gastric cancer surgery.

DESIGN

A prospective cohort study.

SETTING

Hospitalization setting, Nanjing, China.

PARTICIPANTS

We recruited 259 elderly patients undergoing gastric cancer surgery from a tertiary hospital.

MEASUREMENTS

Frailty was assessed by the FP, TFI, mFI-11, and mFI-5 before surgery, respectively. The receiver operating characteristic (ROC) curves were plotted to compared the diagnostic performance of TFI, mFI-11, and mFI-5 using FP as the reference. ROC curves were used to examine the performance of TFI, mFI-11, and mFI-5 in predicting adverse outcomes. The area under the curve (AUC)>0.70 was regarded as an indicator of good performance.

RESULTS

The prevalence of frailty ranged from 8.5% (mFI-11) to 45.9% (TFI). The AUCs of TFI (AUC: 0.764, p<0.001) was significantly greater than that of mFI-11 (AUC: 0.600, p=0.033) and mFI-5 (AUC: 0.600, p=0.0311) in the detection of frailty defined by FP, with quite different sensitivity and specificity at their original cutoffs. TFI and mFI-11 both had statistically significant but similarly inadequate predictive accuracy for adverse outcomes in hospital, including total complications (AUCs: 0.618; 0.621), PLOS (AUCs: 0.593; 0.639), increased hospital costs (AUCs: 0.594; 0.624), and hypoproteinemia (AUCs: 0.573; 0.600). For the mFI-5, only the predictive ability for hypoproteinemia was statistically significant, with poor accuracy (AUC: 0.592, p<0.0055).

CONCLUSION

The TFI performed slightly better than mFI-11 and mFI-5 in our study. Moreover, future studies are needed to further determine an optimal frailty instrument with great diagnostic and predictive accuracy.

The Importance of Taking a Patient-Centered, Community-Based Approach to Preventing and Managing Frailty: A Public Health Perspective

Across the world, life expectancy is increasing. However, the years of life gained do not always correspond to healthy life years, potentially leading to an increase in frailty. Given the extent of population aging, the association between frailty and age and the impact of frailty on adverse outcomes for older people, frailty is increasingly being recognized to be a significant public health concern. Early identification of the condition is important to help older adults regain function and to prevent the negative outcomes associated with the syndrome. Despite the importance of diagnosing frailty, there is no definitive evidence or consensus of whether screening should be routinely implemented. A broad range of screening and assessment instruments have been developed taking a biopsychosocial approach, characterizing frailty as a dynamic state resulting from deficits in any of the physical, psychological and social domains, which contribute to health. All these aspects of frailty should be identified and addressed using an integrated and holistic approach to care. To achieve this goal, public health and primary health care (PHC) need to become the fulcrum through which care is offered, not only to older people and those that are frail, but to all individuals, favoring a life-course and patient-centered approach centered around integrated, community-based care. Public health personnel should be trained to address frailty not merely from a clinical perspective, but also in a societal context. Interventions should be delivered in the individuals' environment and within their social networks. Furthermore, public health professionals should contribute to education and training on frailty at a community level, fostering community-based interventions to support older adults and their caregivers to prevent and manage frailty. The purpose of this paper is to offer an overview of the concept of frailty for a public health audience in order to raise awareness of the multidimensional aspects of frailty and on how these should be addressed using an integrated and holistic approach to care.

Natural Regression of Frailty Among Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVES

Frailty is a dynamic process with potential transitions over time. However, there is limited understanding of the patterns of frailty improvement. We conducted a systematic review and meta-analysis to estimate the natural rate of frailty regression among community-dwelling older adults aged at least 60 years.

RESEARCH DESIGN AND METHODS

Systematic searches for studies reporting frailty improvement were performed in 5 databases (Medline, Embase, CINAHL plus, Web of Science, and PsycINFO) from inception until January 2019.

RESULTS

Twenty-five studies from 26 countries were included. Among a baseline population of more than 50,000 individuals, the pooled prevalence of pre-frailty and frailty was 50.5% (95% confidence interval [CI] 47.8-53.3) and 12.8% (95% CI 9.1-17.0), respectively. During a median follow-up of 3.0 (range 1-10.0) years, 23.3% of surviving pre-frail individuals regressed to a robust state and 35.2% of surviving frail individuals reversed to a pre-frail or robust state. The pooled remission rates among people with pre-frailty and frailty were 80.4 (95% CI 61.7-104.6) and 135.3 (95% CI 98.1-186.5) per 1,000 person-years, respectively. Frailty and pre-frailty improvement rates varied by sex, diagnostic criteria, study region, and follow-up duration. The remission rates were significantly reduced when accounting for progressions to death. The heterogeneity of included studies was high which reflected considerable differences in methodological approach.

DISCUSSION AND IMPLICATIONS

Although frailty is highly prevalent in older people, natural remission is possible and common. Improved understanding of the factors that confer increased likelihood of frailty regression may support the design of interventions to reduce the burden of frailty.

Do European co-residential caregivers aged 50+ have an increased risk of frailty?

One important health challenge associated with ageing is frailty, which has been acknowledged as a new public health priority. However, only a few studies have explored the relationship between providing care at older ages and frailty. The main objective of this study is to assess whether there is an association between providing co-residential care and frailty, according to gender and from a European cross-sectional perspective, among the population aged 50+. Data from 17 European countries that participated in wave 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE) is used (N = 52,073). Multinomial logistic regressions were used to estimate caregivers' chances of frailty. The results show that the prevalence of pre-frailty and frailty differs according to the caregiver's status, gender and the European region. The highest prevalence of pre-frailty was found in the group of female caregivers from Northern countries (57.3%), and the highest prevalence of frailty was found in the group of female caregivers from Southern countries (29.3%). Providing co-residential care is positively associated with the risk of being pre-frail in women, in all European regions (Northern: OR 1.724, 95% CI 1.190-2.496; Central: OR 1.213, 95% CI 1.010-1.456; Eastern: OR 1.227, 95% CI 1.031-1.460; Southern: OR 1.343, 95% CI 1.103-1.634), and with being frail for both genders in the Southern region (female: OR 1.527, 95% CI 1.060-2.200; male: OR 1.644, 95% CI 1.250-2.164). The results of this study suggest that female co-residential caregivers are a greater risk of being pre-frail in all European regions except Southern Europe, where male and female co-residential caregivers are a greater risk of being frail, compared with non-caregivers. European policy makers should create political measures to prevent and reverse frailty among European co-residential caregivers.

Comparison of 6 frailty screening tools in diagnostic properties among Chinese community-dwelling older people

We aimed to compare the diagnostic test accuracy (DTA) of six frailty screening tools against comprehensive geriatric assessment (CGA) in the community. A total of 1177 community-dwelling older people were recruited. Frailty was assessed by purely physical tools including Physical Frailty Phenotype (PFP), FRAIL (fatigue, resistance, ambulation, illness and loss of weight), Study of Osteoporotic Fracture (SOF), and multidimensional tools including Tilburg Frailty Indicator (TFI), Groningen Frailty Indicator (GFI) and Comprehensive Frailty Assessment Instrument (CFAI). The receiver operating characteristic curve analyses were performed. The GFI, TFI and CFAI [areas under the curve (AUCs): 0.78-0.80] had better diagnostic accuracy than SOF, PFP and FRAIL (AUCs: 0.69-0.72) (χ²: 6.37-26.76, P<.05). The optimal cut-offs for the PFP, FRAIL and SOF were identical to their original prefrail cut-offs. These results implicate that the multidimensional tools are more effective to identify frailty in the whole community setting, while the self-report FRAIL may be used to identify the prefrail and facilitate early interventions particularly in the community setting with adequate healthcare resources.

Prevalence and associations of frailty in residents of Australian aged care facilities: findings from a retrospective cohort study

OBJECTIVES

Studies conducted among older people have shown that frailty is a common condition associated with an array of adverse outcomes. The aims of this study were to identify the prevalence and associations of frailty in older people residing in several aged care facilities located in Queensland, Australia.

METHODS

The database used for this study was drawn from the Aged Care Funding Instrument (ACFI) database of an Australian aged care provider, and contained data from ten aged care facilities in Queensland, Australia. A modification of an eFI originally developed by Clegg and colleagues and based on Rockwood's Frailty Index (FI) of cumulative deficits was used to identify frailty.

RESULTS

In total, 592 participants aged 75 years and over were included in the study (66.6% female). Median (IQR) age was 88.0 (9.0) years. Frailty prevalence among the sample was 43.6%, with 46.3% pre-frail and 10.1% not frail. In a multivariate logistic regression analysis incorporating three different models, frailty was significantly associated with three ACFI domains (Nutrition, Depression and Complex Health Care), along with facility size, consistently across two models. In the third model, frailty was also significantly associated with arthritis, diabetes, hypertension, osteoporosis and vision problems, along with male gender.

CONCLUSION

There is a need to develop frailty identification and management programs as part of standard care pathways for older adults residing in aged care facilities. Aged care facilities should consider regular frailty screening in residential aged care residents, along with interventions addressing specific issues such as dysphagia and depression.

Frailty, a multisystem ageing syndrome

The management of frail older people is a key component of aged care. There has been a plethora of tools developed for the diagnosis and screening of frailty. Some of these tools are entering routine clinical practice at a time when the higher healthcare costs involved in caring for older people who are frail have become a potential target for cost-cutting. Yet there is still only limited evidence to support the widespread adoption of frailty tools, and foundational factors impact on their accuracy and validity. Despite the acceptance of frailty as a valid term in research and clinical practice, older people believe the term carries stigma. Such issues indicate that there may be a need to reconsider current approaches to frailty. Recent advances in the science of ageing biology can provide a new framework for reconfiguring how we screen, diagnose, treat and prevent frailty. Frailty can be considered to be a multisystem ageing syndrome of decreased physiological and functional reserve, where the biological changes of ageing are seen in most tissues and organs and are the pathogenic mechanism for frailty. Likewise age-related chronic disease and multimorbidity are syndromes where ageing changes occur in one or multiple systems, respectively. This model focusses diagnostic criteria for frailty onto the biomarkers of ageing and generates new targets for the prevention and treatment of frailty based on interventions that influence ageing biology.

Knowledge and attitude of healthcare professionals to frailty screening in primary care: a systematic review protocol

INTRODUCTION

Frailty is an increasingly common condition in which physiological decline as a result of accumulated deficits renders older people more vulnerable to adverse outcomes. An increasing range of frailty screening programmes have been introduced in primary care to identify frail older people in order to deliver appropriate interventions. However, limited information on the knowledge and attitude of healthcare professionals (HCPs) with respect to frailty screening is known. The aim of this systematic review is to provide evidence on the knowledge and attitude of HCP in terms of frailty screening, and potentially identify barriers and facilitators to frailty screening to improve implementation of frailty screening in primary care.

METHODS/DESIGN

A systematic review of qualitative research will be conducted. Databases searched will be MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO and Web of Science from January 2001 to August 2019. Methods will be reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Population, interest, context and study design methodology was used to develop inclusion and exclusion criteria with HCPs as population, frailty screening as interest and knowledge or attitude of HCPs to frailty screening as context. Studies with a qualitative methodology or a mixed-method design where the qualitative component is analysed separately will also be included. Quality appraisal will be carried out using the Joanna Briggs Institute appraisal tool for qualitative studies. Data will be extracted from each selected study with thematic framework analysis used to synthesise findings.

ETHICS AND DISSEMINATION

This systematic review does not require ethical approval as primary data will not be collected. The findings will be disseminated at conferences and in a relevant academic journal. This review will assist HCPs and relevant stakeholders to tackle the challenges of frailty screening in primary care.

Frailty Confers High Mortality Risk across Different Populations: Evidence from an Overview of Systematic Reviews and Meta-Analyses

We performed an overview of systematic reviews and meta-analyses to summarize available data regarding the association between frailty and all-cause mortality. Medline, Embase, CINAHL, Web of Science, PsycINFO, and AMED (Allied and Complementary Medicine) databases were searched until February 2020 for meta-analyses examining the association between frailty and all-cause mortality. The AMSTAR2 checklist was used to evaluate methodological quality. Frailty exposure and the risk of all-cause mortality (hazard ratio [HR] or relative risk [RR]) were displayed in forest plots. We included 25 meta-analyses that pooled data from between 3 and 20 studies. The number of participants included in these meta-analyses ranged between <2000 and >500,000. Overall, 56%, 32%, and 12% of studies were rated as of moderate, low, and critically low quality, respectively. Frailty was associated with increased risk of all-cause mortality in 24/24 studies where the HR/RRs ranged from 1.35 [95% confidence interval (CI) 1.05-1.74] (patients with diabetes) to 7.95 [95% CI 4.88-12.96] (hospitalized patients). The median HR/RR across different meta-analyses was 1.98 (interquartile range 1.65-2.67). Pre-frailty was associated with a significantly increased risk of all-cause mortality in 7/7 studies with the HR/RR ranging from 1.09 to 3.65 (median 1.51, IQR 1.38-1.73). These data suggest that interventions to prevent frailty and pre-frailty are needed.

Factors influencing communication about frailty in primary care: A scoping review

OBJECTIVE

To summarise the available evidence on the factors influencing communication about frailty in the primary care setting.

METHODS

We conducted a scoping review, searching five electronic databases (PubMed, Scopus, CINAHL, PsycINFO, and ProQuest) for studies addressing communication about frailty in primary care practice. Reference list and grey literature searching was conducted to identify additional articles. A narrative descriptive method was used to synthesise the findings.

RESULTS

The search identified 3185 articles and 37 were included in the review. We identified five categories of factors influencing communication about frailty at the consumer, healthcare provider, and system levels: (1) consumer perceptions, information needs, and communication preferences; (2) healthcare providers' knowledge, capacities, and attitudes; (3) clinical communication skills and training; (4) availability of information and communication technologies; and (5) care coordination, collaboration, and case management.

CONCLUSION

Findings offer considerations for the design and delivery of initiatives to improve communication about frailty in primary care both at the local clinical level and at the broader level of healthcare service delivery.

PRACTICE IMPLICATIONS

Healthcare providers and systems require practical, evidence-informed guidance regarding the development of a systematic approach to the quality and timing of communication about frailty in healthcare encounters.

Randomized trial results of alerting primary clinicians to severe weight loss among older adults in the Low Indexes of Metabolism Intervention Trial part A

AIM

To test whether alerting clinicians to severe weight loss in older patients leads to higher dietitian visit rates, to higher body mass index (BMI) levels and, mainly, to lower annual death risk.

METHODS

The randomized controlled trial included patients aged ≥75 years, with BMI ≤23 kg/m² that decreased ≥2 kg/m² during the previous 2 years. All participants received usual care. Additionally, an email alert was sent only to clinicians of participants assigned to the email alert group. The follow-up period was 12 months.

RESULTS

Among 706 participants (mean age 83 ± 6 years; mean baseline BMI 20.5 kg/m² ), the BMI record was updated in 541 (77%) participants, and 123 participants died. Dietitian visits were reported for 22 patients (6%) in the email group (n = 362) and 14 patients (4%) in the control group (n = 344; OR 1.5, 95% CI 0.8-2.9; P = 0.24). Measured BMI were raised by a mean of 0.69 (95% CI 0.43-0.95) kg/m² versus 0.79 (95% CI 0.48-1.1) kg/m² (P = 0.63). A total of 77 patients (21%) died in the intervention group versus 47 (14%) in the control group (P = 0.008; number needed to harm = 13; 95% CI 7-43).

CONCLUSIONS

In this trial, alerting clinical staff to severe weight loss in patients aged ≥75 years was not associated with higher visit rates to a dietitian or change in BMI, but was associated with a significantly higher death rate than usual clinical care. Geriatr Gerontol Int 2020; 20: 329-335.

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.

Prevalence of Frailty in Brazilian Older Adults: A Systematic Review and Meta-analysis

OBJECTIVES

Frailty is characterized by a functioning decline in multiple systems accompanied by an increase in individual's vulnerability to stressors. It appears to be higher in low and middle-income countries compared with high-income ones. This study aimed to evaluate the prevalence of frailty in non-institutionalized Brazilian older adults.

DESIGN

a systematic review and meta-analysis study.

SETTING

Cross-sectional and prospective data from Brazil.

PARTICIPANTS

non-institutionalized adults aged 60 and older.

METHODS

Electronic searches were performed in PubMed/MEDLINE, LILACS, SCOPUS and Web of Science, considering the studies published between March 2001 and July 2018, using a combination of the following terms and correlates: "elder" AND "frail" AND "prevalence" AND "Brazil". Two independent reviewers selected studies according to the inclusion criteria. Disagreements were resolved by a third reviewer (title/abstract) and by consensus. Studies with samples ≥221 subjects were considered for meta-analysis.

RESULTS

28 studies were included, while 18 had the data meta-analyzed. The majority of studies (61%) included older adults only from the Southeastern region. The number of subjects ranged from 53 to 5,532 individuals (N = 17,604) and the average age ranged from 65.6 to 85.5 years. The overall prevalence of frailty was 24%. When considering the different assessment methods, the prevalence was lower for frailty phenotype (16%) compared with other criteria (40%). Regarding sex, the prevalence of frailty was similar for women (28%) and men (25%). The prevalence of frailty was higher in older adults recruited from health care services (30%) compared to community ones (22%).

CONCLUSION

In Brazil, the overall prevalence of frailty in non-institutionalized older adults is higher than observed from more developed countries. However, it may vary according to the assessment methods and settings.

Diagnostic test accuracy of self-reported screening instruments in identifying frailty in community-dwelling older people: A systematic review

Against a backdrop of aging populations worldwide, it has become increasingly important to identify frailty screening instruments suitable for community settings. Self-reported and/or administered instruments might offer significant simplicity and efficiency advantages over clinician-administered instruments, but their comparative diagnostic test accuracy has yet to be systematically examined. The aim of this systematic review was to determine the diagnostic test accuracy of self-reported and/or self-administered frailty screening instruments against two widely accepted frailty reference standards (the frailty phenotype and the Frailty Index) within community-dwelling older adult populations. We carried out a systematic search of the Embase, CINAHL, MEDLINE, PubMed, Web of Science, PEDro, PsycINFO, ProQuest Dissertations, Open Grey and GreyLit databases up to April 2017 (with an updated search carried out over May-July 2018) to identify studies reporting comparison of self-reported and/or self-administered frailty screening instruments against an appropriate reference standard, with a minimum sensitivity threshold of 80% and specificity threshold of 60%. We identified 24 studies that met our selection criteria. Four self-reported screening instruments across three studies met minimum sensitivity and specificity thresholds. However, in most cases, study design considerations limited the reliability and generalizability of the results. Additionally, meta-analysis was not carried out, because no more than three studies were available for any of the unique combinations of index tests and reference standards. Although the present study has shown that a number of self-reported frailty screening instruments reported sensitivity and specificity within a desirable range for community application, additional diagnostic test accuracy studies are required.

Changes in frailty among ICU survivors and associated factors: Results of a one-year prospective cohort study using the Dutch Clinical Frailty Scale

PURPOSE

Frailty is an important predictor for the prognosis of intensive care unit (ICU) patients. This study examined changes in frailty in the year after ICU admission, and its associated factors.

MATERIALS AND METHODS

Prospective cohort study including adult ICU patients admitted between July 2016-December 2017. Frailty was measured using the Clinical Frailty Scale (CFS), before ICU admission, at hospital discharge, and three and 12 months after ICU admission. Multivariable linear regression was used to explore factors associated with frailty changes.

RESULTS

Frailty levels changed among 1300 ICU survivors, with higher levels at hospital discharge and lower levels in the following months. After one year were 42% of the unplanned, and 27% of the planned patients more frail. For both groups were older age, longer hospital length of stay, and discharge location associated with being more frail. Male sex, higher education level and mechanical ventilation were associated with being less frail in the planned patients.

CONCLUSION

One year after ICU admission, 42% and 27% of the unplanned and planned ICU patients, respectively, were more frail. Insight in the associated factors will help to identify patients at risk, and may help in informing patients and their family members.

Management of frailty: opportunities, challenges, and future directions

Frailty is a complex age-related clinical condition characterised by a decline in physiological capacity across several organ systems, with a resultant increased susceptibility to stressors. Because of the heterogeneity of frailty in clinical presentation, it is important to have effective strategies for the delivery of care that range across the continuum of frailty severity. In clinical practice, we should do what works, starting with frailty screening, case identification, and management of frailty. This process is unarguably difficult given the absence of an adequate evidence base for individual and health-system interventions to manage frailty. We advocate change towards individually tailored interventions that preserve an individual's independence, physical function, and cognition. This change can be addressed by promoting the recognition of frailty, furthering advancements in evidence-based treatment options, and identifying cost-effective care delivery strategies.
