The frailty dilemma. Review of the predictive accuracy of major frailty scores

Effects of interactive boxing-cycling on dual-task walking and prefrontal cortex activation in older adults with cognitive frailty: A randomized controlled trial

Older adults with cognitive frailty often have impaired dual-task walking and prefrontal cortex (PFC) activation. Combining cycling with interactive boxing offers an innovative and interesting dual-task training to challenge both physical and cognitive skills. This study investigated the effects of interactive boxing-cycling on this population. Thirty-nine participants were assigned to the interactive boxing-cycling group (n = 20) or the stationary cycling group (n = 19) for 36 sessions over 12 weeks. The outcomes included dual-task walking performance, PFC activation, cognitive function, and frailty scores. Results showed the interactive boxing-cycling group had greater improvements in dual-task walking speed and cost and beneficially reduced oxygenated hemoglobin levels compared to the stationary group. Furthermore, both groups improved in frailty and cognition, but the interactive boxing-cycling group had better effects on general and specific cognitive function. Interactive boxing-cycling is an efficient intervention to enhance dual-task walking and PFC activation in older adults with cognitive frailty.

Not All Frailty Assessments Are Created Equal: Comparability of Electronic Health Data-Based Frailty Assessments in Assessing Older People in Residential Care

Objectives: To evaluate the comparability of frailty assessment tools - the electronic frailty index (eFI), retrospective electronic frailty index (reFI), and clinical frailty scale (CFS) - in older residents of care facilities. Methods: Data from 813 individuals aged 65 or older, with frailty and co-morbidities, collected between 2022 and 2023, were analysed using various statistical methods. Results: The results showed significant differences in frailty classification among the tools: 78.3% were identified as moderately to severely frail by eFI, 59.6% by reFI, and 92.1% by CFS. Statistical tests confirmed significant differences (p < .05) in their assessments, indicating variability in measurement methods. Discussion: This study advances the understanding of frailty assessment within aged-care settings, highlighting the differences in the efficacy of these assessment tools. It underscores the challenges in frailty assessments and emphasizes the need for continuous refinement of assessment methods to address the diverse facets of frailty in aged care.

Visualizing Worldwide Prevalence of Age-Related Dual Sensory Loss

Objectives: This study aims to create a first visualization of global prevalence of age-related dual sensory loss (DSL), significantly affecting older people's quality of life. Methods: Data from World Health Organization (WHO) regions, particularly African, American, and European, were analyzed. The study focused on DSL onset and prevalence, using adjusted life expectancy for regional comparison. Results: There were notable regional variations in DSL onset and prevalence. The African region showed consistent data, thanks to standardized methods from the World Federation of the Deafblind. However, global patterns varied when adjusted for life expectancy, hinting at possible DSL prevalence stabilization at older ages. Discussion: The study identifies a lack of standardization in DSL prevalence research regarding definitions, methodologies, and reporting. It calls for more uniform and thorough research methods for accurate global DSL understanding. The research highlights the complexity and challenges in determining DSL prevalence worldwide.

Comparing four frailty assessment tools against seven-year mortality in the Malaysian elders longitudinal research study

AIM

Several frailty assessment tools are currently used in clinics and research, however, there appears to be a lack of head-to-head comparisons between these tools among older adults in developing countries. This study compared the Cardiovascular Health Study, Study of Osteoporotic Fractures, the Tilburg Frailty Indicator and the Canadian Study of Health and Aging frailty assessment tools and evaluated performance of these individual frailty assessment tools with mortality.

METHODS

This prospective cohort study utilized stratified simple random sampling to recruit 1614 participants from the Malaysian Elders Longitudinal Research aged above 55 years within the Klang Valley region from 2013 to 2015. Individual items for the frailty tools, alongside baseline physical and cognitive measures were extracted from the initial survey. Mortality data up to 31 December 2020 were obtained through data linkage from the death registry data obtained from the Malaysian National Registration Department.

RESULTS

Data were available for over 1609 participants, age (68.92 ± 7.52) years and 57 % women, during recruitment. Mortality data revealed 13.4 % had died as of 31 December 2020. Five to 25 % of our study population fulfilled the criteria for frailty using all four frailty tools. This study found an increased risk of mortality with frailty following adjustments for potential factors of falls, total number of illnesses and cognitive impairment, alongside moderate to strong correlation and agreement between frailty tools.

CONCLUSION

Frailty was associated with increased mortality. All four frailty assessment tools can be used to assess frailty within the Malaysian older adult population. The four available tools, however, may not be interchangeable.

Handgrip strength as a diagnostic tool for frailty risk in elderly patients with moderate to severe asthma

OBJECTIVE

To evaluate handgrip strength (HGS) as a diagnostic tool for frailty risk in elderly patients with asthma, as well as to investigate the prevalence of frailty in this population.

METHODS

This was a cross-sectional study including 96 patients ≥ 60 years of age diagnosed with moderate to severe asthma and treated at a tertiary referral center in Brazil. We measured HGS using a calibrated hydraulic hand dynamometer. We used a frailty scale and the AUC to assess the diagnostic accuracy of the HGS test.

RESULTS

The median age of participants was 67 years. Most (78%) were women and non-White (91%) of low socioeconomic status. HGS identified those at risk for frailty, with an AUC of 71.6% (61.5-80.4%; p < 0.002), as well as a sensitivity of 73.58% and a specificity of 67.53%, on the basis of a cutoff of ≤ 19 kgf.

CONCLUSIONS

HGS appears to be a simple, reliable tool for clinicians to determine frailty risk in older asthma patients in a point-of-care setting.

Prevalence and factors associated with frailty in older hospitalized patients

OBJECTIVES

This study aimed to determine the prevalence and factors associated with frailty in older hospitalized patients.

METHODS

The point-prevalence study was completed on 263 patients aged 65 and over hospitalized in internal medicine and surgical clinics at a tertiary hospital in Türkiye. Data were collected between July 19th and July 22nd, 2021. A comprehensive geriatric assessment was performed on the participants. The Edmonton Frailty Scale (EFS) and FRAIL scale were used for frailty assessment.

RESULTS

The mean age of the individuals was 72.40 ± 6.42, 51.7% were female, and 63.9% were hospitalized in internal medicine and surgical units. The prevalence of frailty was 57.4% according to the FRAIL scale and 46.8% according to EFS. Factors affecting frailty were gender (OR 3.36, 95% CI 1.48-7.64), comorbidity (OR 1.29, 95% CI 1.01-1.64), polypharmacy (OR 0.33, 95% CI 0.13-0.80), history of falling in the last year (OR 3.54, 95% CI 1.34-9.35), incontinence (OR 5.93, 95% CI 2.47-14.27), and functional dependency (ADL, OR 0.65, 95% CI 0.46-0.92; IADL, OR 0.59, 95% CI 0.46-0.76). This model correctly predicted the participants' frailty at 70.5%.

CONCLUSIONS

The importance of frailty, which affects one out of every two hospitalized older persons, to the health care system should not be overlooked. Considering the increasing trend of the aging person population, national and global plans should be made to prevent and manage frailty.

Interaction between geriatric syndromes in predicting three months mortality risk

OBJECTIVES

Capturing frailty using a quick tool has proven to be challenging. We hypothesise that this is due to the complex interactions between frailty domains. We aimed to identify these interactions and assess whether adding interactions between domains improves mortality predictability.

METHODS

In this retrospective cohort study, we selected all patients aged 70 or older who were admitted to one Dutch hospital between April 2015 and April 2016. Patient characteristics, frailty screening (using VMS (Safety Management System), a screening tool used in Dutch hospital care), length of stay, and mortality within three months were retrospectively collected from electronic medical records. To identify predictive interactions between the frailty domains, we constructed a classification tree with mortality as the outcome using five variables: the four VMS-domains (delirium risk, fall risk, malnutrition, physical impairment) and their sum. To determine if any domain interactions were predictive for three-month mortality, we performed a multivariable logistic regression analysis.

RESULTS

We included 4,478 patients. (median age: 79 years; maximum age: 101 years; 44.8% male) The highest risk for three-month mortality included patients that were physically impaired and malnourished (23% (95%-CI 19.0-27.4%)). Subgroups had comparable three-month mortality risks based on different domains: malnutrition without physical impairment (15.2% (96%-CI 12.4-18.6%)) and physical impairment and delirium risk without malnutrition (16.3% (95%-CI 13.7-19.2%)).

DISCUSSION

We showed that taking interactions between domains into account improves the predictability of three-month mortality risk. Therefore, when screening for frailty, simply adding up domains with a cut-off score results in loss of valuable information.

Systematic review of the utility of the frailty index and frailty phenotype to predict all-cause mortality in older people

BACKGROUND

Current guidelines for healthcare of community-dwelling older people advocate screening for frailty to predict adverse health outcomes, but there is no consensus on the optimum instrument to use in such settings. The objective of this systematic review of population studies was to compare the ability of the frailty index (FI) and frailty phenotype (FP) instruments to predict all-cause mortality in older people.

METHODS

Studies published before 27 July 2022 were identified using Ovid MEDLINE, Embase, Scopus, Web of Science and CINAHL databases. The eligibility criteria were population-based prospective studies of community-dwelling older adults (aged 65 years or older) and evaluation of both the FI and FP for prediction of all-cause mortality. The Scottish Intercollegiate Guidelines Network's Methodology checklist was used to assess study quality. The areas under the receiver operator characteristic curves (AUC) were compared, and the proportions of included studies that achieved acceptable discriminatory power (AUC>0.7) were calculated for each frailty instrument. The results were stratified by the use of continuous or categorical formats of each instrument. The review was reported in accordance with the PRISMA and SWiM guidelines.

RESULTS

Among 8 studies (range: 909 to 7713 participants), both FI and FP had comparable predictive power for all-cause mortality. The AUC values ranged from 0.66 to 0.84 for FI continuous, 0.60 to 0.80 for FI categorical, 0.63 to 0.80 for FP continuous and 0.57 to 0.79 for FP categorical. The proportion of studies achieving acceptable discriminatory power were 75%, 50%, 63%, and 50%, respectively. The predictive ability of each frailty instrument was unaltered by the number of included items.

CONCLUSIONS

Despite differences in their content, both the FI and FP instruments had modest but comparable ability to predict all-cause mortality. The use of continuous rather than categorical formats in either instrument enhanced their ability to predict all-cause mortality.

Physical activity for chronic pancreatitis: a systematic review

BACKGROUND

Chronic pancreatitis (CP) is a progressive inflammatory disorder of the pancreas. Sarcopenia is a degenerative loss of skeletal muscle mass, quality, and strength and is commonly associated with chronic pancreatitis. Regular physical activity and adequate functional fitness have been found to ameliorate the risk and effects of sarcopenia in other chronic diseases. The objective of this systematic review was to collate all the published evidence which has examined any type of physical activity as an intervention in the chronic pancreatitis patient population.

METHODS

This systematic review was conducted in accordance with the PRISMA guidelines. The search strategy was designed by the medical librarian (DM) for Embase and then modified for the other search platforms. Two of the researchers (BM) and (AM) then performed the literature search using the databases Embase, Medline, CINAHL, and Web of Science.

RESULTS

An electronic identified a total of 571 references imported to Covidence as 420 when the duplicates (151) were removed. 420 titles were screened and 390 were removed as not relevant from their titles. 30 full text papers were selected and from these, only one full text paper was deemed suitable for inclusion.

CONCLUSIONS

There is currently insufficient evidence to advise physical activity in the chronic pancreatitis population. However, given the evidence to support physical activity in many other chronic diseases this review highlights the need for urgent investigation of physical activity as an intervention on this specific patient population.

Development of a Clinical Prediction Rule for Adverse Events in Multimorbid Patients in Emergency and Hospitalisation

(1) Background: There is currently a global consensus that the quality of comprehensive care for acutely hospitalised elderly people should include addressing functionality and mobility, cognitive status, prevention of pressure ulcers, urinary incontinence, falls and delirium, as well as pain control and medication-related problems. The aim of this study is to develop and validate a clinical prediction rule for multimorbid patients admitted to an acute care hospital unit for any of the five adverse events included in our vulnerability pentad: falls, pressure ulcers, urinary incontinence, pain and delirium. (2) Methods: Longitudinal analytical clinimetric study, with two cohorts. The study population will consist of multimorbid patients hospitalised for acute care, referred from the Emergency Room. A clinical prediction rule will be proposed, incorporating predictive factors of these five adverse outcomes described. This study has received funding, awarded in November 2020 (PI-0107-2020), and was approved in October 2019 by the Research Ethics Committee ″Costa del Sol″. (3) Conclusions: Preventing adverse events in hospitalised patients is particularly important for those with multimorbidity. By applying a clinical prediction rule to detect specific risks, an estimate can be obtained of their probability of occurrence.

Variability and agreement of frailty measures and risk of falls, hospital admissions and mortality in TILDA

Little is known about the within-person variability of different frailty instruments, their agreement over time, and whether use of repeat assessments could improve the strength of associations with adverse health outcomes. Repeat measurements recorded in 2010–2011 (Wave 1) and 2012 (Wave 2) from The Irish Longitudinal Study on Ageing (TILDA) were used to classify individuals with frailty using the frailty phenotype (FP) and frailty index (FI). Within-person variability and agreement of frailty classifications were assessed using ANOVA and kappa (K) statistics, respectively. Associations of each frailty measure (wave 1, wave 2, or mean of both waves) with risk of falls, hospitalisations and all-cause mortality were assessed using logistic regression. Among 7455 individuals (mean age 64.7 [SD 9.9] years), within-person SD was 0.664 units (95% CI 0.654–0.671) for FP and 2 health deficits (SD 0.050 [0.048–0.051]) for FI. Agreement of frailty was modest for both measures, but higher for FI (K 0.600 [0.584–0.615]) than FP (K 0.370 [0.348–0.401]). The odds ratios (ORs) for all-cause mortality were higher for frailty assessed using the mean of two versus single measurements for FI (ORs for mortality 3.5 [2.6–4.9] vs. 2.7 [1.9–3.4], respectively) and FP (ORs for mortality 6.9 [4.6–10.3] vs. 4.0 [2.8–5.635], respectively). Frailty scores based on single measurements had substantial within-person variability, but the agreement in classification of frailty was higher for FI than FP. Frailty assessed using the mean of two or more measurements recorded at separate visits was more strongly associated with adverse health outcomes than those recorded at a single visit.

Frailty and emergency abdominal surgery: A systematic review and meta-analysis

INTRODUCTION

Patients aged ≥65 years currently account for approximately 55% of all emergent operations. However, these patients account for 75% of post-operative mortality. Older age has long been associated with adverse outcomes from emergency surgery. However, old age is a heterogenous state. Recent studies have indicated that frailty may more accurately reflect true biological age and perioperative risk than chronological age alone in patients undergoing elective surgery. Few studies have evaluated the impact of frailty on post-operative outcomes in this setting.

METHODS

A systematic, electronic search for relevant publications was performed in November 2019 using Pubmed and Embase from 2009 to 2019. The latest search for articles was performed on February 16th, 2020. Articles were excluded if frailty was not measured using a frailty tool, or if patients did not undergo emergency general surgery (EGS).

RESULTS

The prevalence of frailty amongst patients undergoing emergency abdominal surgery was 30.8%. The all-cause mortality rate was 15.68%. The mortality rate amongst the frail undergoing EGS was 24.7%. Frailty was associated with an increased mortality rate compared with the non-frail (odds ratio (OR) 4.3, 95% CI 2.25-8.19%, p < 0.05, I² = 80%).

CONCLUSIONS

There is strong evidence to suggest that frailty in the older population predicts post-operative mortality, complications, prolonged length of stay and the loss of independence. Collaborative working with medicine for the elderly physicians to target modifiable aspects of the frailty syndrome in the perioperative pathway may improve outcomes. Frailty scoring should be integrated into acute surgical assessment practice to aid decision-making and development of novel postoperative strategies.

Web-based software applications for frailty assessment in older adults: a scoping review of current status with insights into future development

BACKGROUND

A crucial aspect of continued senior care is the early detection and management of frailty. Developing reliable and secure electronic frailty assessment tools can benefit virtual appointments, a need especially relevant in the context of the COVID-19 pandemic. An emerging effort has targeted web-based software applications to improve accessibility and usage. The objectives of this scoping review are to identify and evaluate web-based frailty assessment tools currently available and to identify challenges and opportunities for future development.

METHODS

We conducted a review with literature (e.g., using MEDLINE databases) and Google searches (last updated on October 10, 2021). Each of the identified web applications were assessed based on eight featured categories and assigned a rating score accordingly.

RESULTS

Twelve web-based frailty assessment applications were found, chiefly provided by the USA (50%) or European countries (41%) and focused on frailty grading and outcome prediction for specific patient groups (59%). Categories that scored well among the applications included the User Interface (2.8/3) and the Cost (2.7/3). Other categories had a mean score of 1.6/3 or lower. The least developed feature was Data Saving.

CONCLUSIONS

Web-based applications represent a viable option for remote frailty assessments and multidisciplinary integrated care of older adults. Despite the available web-based frailty assessments on the Internet, many missed certain needed features for professional use in healthcare settings. This situation calls for fully comprehensive web-based applications, taking into consideration a number of key functions linking graphical user interface and functionalities, and paying special attention to secure data management.

The state of frailty in research: A mapping review of its clinical applicability to practice

Research on frailty has expanded in the last decade, but direct evidence supporting its implementation in clinical practice may be limited. This mapping review synthesizes the contexts-of-use and overall clinical applicability of recent pre-COVID frailty research. We sampled 476 articles from articles published on frailty in PubMed and EMBASE in 2017-2018, of which 150 articles were fully appraised for the contexts-of-use, definitions, and interventions. A clinical applicability framework was used to classify articles as practice-changing, practice-informing, or not practice-informing. Of the 476 sampled articles, 31% (n = 150) used frailty in functions that could inform a clinical indication: predictor or mediator (26%, n = 125), selection criterion (3%, n = 15), and effect modifier (2%, n = 10). Articles spanned all health disciplines, and cohort studies comprised 91% (n = 137) of studies and trials 9% (n = 13). Thirty-eight frailty definitions using varied cut-offs and a wide range of interventions were identified. Among all articles, 13% (n = 63) of articles were practice-informing, 2% (n = 11) potentially practice-changing, and 0.2% (n = 1) clearly practice-changing. Lack of well-defined intervention and identifiable effect (96%) or originality (83%) were predominant reasons reducing applicability. Only a minority of recent frailty research provides direct evidence of applicability to practice. Future research on frailty should focus on translating frailty, as a risk factor, into a clinical indication and address definition ambiguity.

A narrative review of frailty assessment in older patients at the emergency department

Optimizing emergency care for the aging population is an important future challenge, as the proportion of older patients at the emergency department (ED) rapidly increases. Older patients, particularly those who are frail, have a high risk of adverse outcomes after an ED visit, such as functional decline, institutionalization, and death. The ED can have a key position in identifying frail older patients who benefit most from comprehensive geriatric care [including delirium preventive measures, early evaluation of after-discharge care, and a comprehensive geriatric assessment (CGA)]. However, performing extensive frailty assessment is not suitable at the ED. Therefore, quick and easy-to-use instruments are needed to identify older patients at risk for adverse outcomes. This narrative review outlines the importance and complexity of frailty assessment at the ED. It aligns the available screening instruments, including clinical judgment as frailty assessment, and summarizes arguments for and against frailty assessment at the ED.

The Emergency Surgery Frailty Index (EmSFI): development and internal validation of a novel simple bedside risk score for elderly patients undergoing emergency surgery

BACKGROUND

Frailty assessment has acquired an increasing importance in recent years and it has been demonstrated that this vulnerable profile predisposes elderly patients to a worse outcome after surgery. Therefore, it becomes paramount to perform an accurate stratification of surgical risk in elderly undergoing emergency surgery.

STUDY DESIGN

1024 patients older than 65 years who required urgent surgical procedures were prospectively recruited from 38 Italian centers participating to the multicentric FRAILESEL (Frailty and Emergency Surgery in the Elderly) study, between December 2016 and May 2017. A univariate analysis was carried out, with the purpose of developing a frailty index in emergency surgery called "EmSFI". Receiver operating characteristic curve analysis was then performed to test the accuracy of our predictive score.

RESULTS

784 elderly patients were consecutively enrolled, constituting the development set and results were validated considering further 240 consecutive patients undergoing colorectal surgical procedures. A logistic regression analysis was performed identifying different EmSFI risk classes. The model exhibited good accuracy as regard to mortality for both the development set (AUC = 0.731 [95% CI 0.654-0.772]; HL test χ² = 6.780; p = 0.238) and the validation set (AUC = 0.762 [95% CI 0.682-0.842]; HL test χ² = 7.238; p = 0.299). As concern morbidity, our model showed a moderate accuracy in the development group, whereas a poor discrimination ability was observed in the validation cohort.

CONCLUSIONS

The validated EmSFI represents a reliable and time-sparing tool, despite its discriminative value decreased regarding complications. Thus, further studies are needed to investigate specifically surgical settings, validating the EmSFI prognostic role in assessing the procedure-related morbidity risk.

The Accuracy of Four Frequently Used Frailty Instruments for the Prediction of Adverse Health Outcomes Among Older Adults at Two Dutch Emergency Departments: Findings of the AmsterGEM Study

STUDY OBJECTIVE

Older adults presenting to the emergency department (ED) are at high risk of adverse health outcomes. This study aimed to evaluate the accuracy of 4 frequently used screening instruments for the prediction of adverse health outcomes among older adults in the ED.

METHODS

This was a prospective cohort study in patients ≥70 years of age presenting to the ED in 2 hospitals in the Netherlands. Screening instruments included the acutely presenting older patient screening program (APOP) (providing 2 risk scores-functional decline [APOP1] and mortality [APOP2]), the International Resident Assessment Instrument Emergendy Department screener (InterRAI ED), the Identification of Seniors At Risk-Hospitalized Patients (ISAR-HP), and the safety management system (VMS). The primary outcome measure was a composite outcome encompassing functional decline, institutionalization, and mortality at 3 months after ED presentation. Other follow-up time points were 1 and 6 months. Analyses were performed to assess prognostic accuracy.

RESULTS

In total, 889 patients were included. After 3 months, 267 (31%) patients experienced at least 1 adverse outcome. The positive likelihood ratio ranged from 1.67 (VMS) to 3.33 (APOP1), and the negative likelihood ratio ranged from 0.41 (ISAR-HP) to 0.88 (APOP2). Sensitivity ranged from 17% (APOP2) to 74% (ISAR-HP), and specificity ranged from 63% (ISAR-HP) to 94% (APOP2). The area under the curve ranged from 0.62 (APOP2) to 0.72 (APOP1 and ISAR-HP). Calibration was reasonable for APOP1 and VMS. The prognostic accuracy was comparable across all outcomes and at all follow-up time points.

CONCLUSION

The frailty screening instruments assessed in this study showed poor to moderate prognostic accuracy, which brings into question their usability in the prediction of adverse health outcomes among older adults who present to the ED.

Influence of foot pain on frailty symptoms in an elderly population: a case-control study

BACKGROUND

Frailty is a condition that can increase the risk of falls. In addition, foot disorders can negatively influence elderly people, thus affecting their condition of frailty.

OBJECTIVE

To determine whether foot pain can influence a greater degree of frailty.

DESIGN AND SETTING

Cross-sectional descriptive study conducted at the University of Valencia, Valencia, Spain.

METHODS

A sample older than 60 years (n = 52), including 26 healthy subjects and 26 foot pain patients, was recruited. Frailty disability was measured using the 5-Frailty scale and the Edmonton Frailty scale (EFS).

RESULTS

There were statistically significant differences in the total EFS score and in most of its subscales, according to the Mann-Whitney U test (P < 0.05). In addition, foot pain patients presented worse scores (higher 5-Frailty scores) than did healthy patients, regarding matched-paired subjects (lower EFS scores). With regard to the rest of the measurements, there were no statistically significant differences (P > 0.05). The highest scores (P < 0.001) were for fatigue on the 5-Frailty scale and the EFS, and for the subscale of independence function in EFS.

CONCLUSIONS

These elderly patients presented impairment relating to ambulation and total 5-Frailty score, which seemed to be linked to the presence of frailty syndrome and foot disorders.

Preoperative quality of life as prediction for severe postoperative complications in gynecological cancer surgery: results of a prospective study

PURPOSE

The aim of this study was to investigate preoperative quality of life (QoL) as a predictive tool for severe postoperative complications (POC) in gynecological cancer surgery.

METHODS

This is a prospective study of patients undergoing gynecologic cancer surgery at an academic center in Germany. QoL was assessed by the EORTC Quality of Life Questionnaire (QLQ-C30) and the NCCN Distress Thermometer (DT). Several geriatric assessment tools have been applied. POC were graded using Clavien-Dindo criteria. Using multivariable logistic regression models, we identified predictive clinical characteristics for postoperative complications.

RESULTS

Within 30 days of surgery, 40 patients (18%) experienced grade ≥ 3b complications including 9 patients (4%) who died. The dominant complication was anastomosis insufficiency with 13 patients (5.8%). In the multivariable stepwise logistic regression through all univariate significant variables, we found that impaired physical functioning was predictive of POC, defined by an EORTC score < 70 (OR 5.08, 95% CI 2.23-11.59, p < 0.001). Regarding symptoms nausea/vomiting assessed as an EORTC score > 20 (OR 3.08, 95% CI 1.15-8.26, p = 0.025) indicated a significant predictive value. Being overweight or obese (BMI > 25) were also identified as predictive factors (OR 5.44, 95% CI 2.04-14.49, p = 0.001) as were reduced Mini Mental State Examination (MMSE) results < 27 (OR 7.94, 95% CI 1.36-45.46, p = 0.02).

CONCLUSION

Preoperative QoL measurements could help to predict postoperative complications in patients with gynecological cancer. Patients with limitations of mobility, debilitating symptoms and cognitive impairment have an increased risk for developing severe POC.

Aging, Frailty, and the Microbiome-How Dysbiosis Influences Human Aging and Disease

The human gut microbiome is a collection of bacteria, protozoa, fungi, and viruses that coexist in our bodies and are essential in protective, metabolic, and physiologic functions of human health. Gut dysbiosis has traditionally been linked to increased risk of infection, but imbalances within the intestinal microbial community structure that correlate with untoward inflammatory responses are increasingly recognized as being involved in disease processes that affect many organ systems in the body. Furthermore, it is becoming more apparent that the connection between gut dysbiosis and age-related diseases may lie in how the gut microbiome communicates with both the intestinal mucosa and the systemic immune system, given that these networks have a common interconnection to frailty. We therefore discuss recent advances in our understanding of the important role the microbiome plays in aging and how this knowledge opens the door for potential novel therapeutics aimed at shaping a less dysbiotic microbiome to prevent or treat age-related diseases.

The reliability, validity, and sensitivity of the Edmonton Frail Scale (EFS) in older adults with foot disorders

The Edmonton Frail Scale (EFS) is an index employed to measure alterations related to frailty. The main objective in this research was to develop the EFS short-form (EFS-SF) and to evaluate its validity, reliability, and sensitivity to predict frailty disability outcomes in elderly patients with foot disabilities.

RESULTS

Exploratory factor analysis (EFA) of the EFS-SF revealed the presence of three components, as in the original EFA. There were significant differences (p < 0.05) in the study population for several of the EFS and 5-item FRAIL scale indicators. The highest correlation (Pearson R = 0.871; p < 0.001) was found for the first component of the EFS-SF. Finally, the Cronbach alpha was 0.864 which indicated a high level of internal consistency.

CONCLUSION

The EFS-SF is a reliable and valid instrument to measure frailty in patients with and without foot disabilities.

METHOD

A cross sectional descriptive study was carried out. The study population was aged over 60 years (n = 66) and comprised 29 men and 37 women. Frailty disorders were registered by using the EFS, 5-item FRAIL scale, and the Geriatricians' Clinical Impression of Frailty (GCIF) scale. EFA was employed to locate potential constituents of the EFS, with scores ranging from 0.596 to 0.946 for each of the sub scales: (1) cognitive and general health status; (2) medication and nutrition status; and (3) functional and physiological status, thus revealing that the EFS-SF comprised three components, a reduction compared to the nine in the original EFS.

Can Fried Frailty Score predict postoperative morbidity and mortality in gynecologic cancer surgery? Results of a prospective study

BACKGROUND

Aim of this study is to evaluate the predictive ability of Fried Frailty Score for surgical outcomes in patients undergoing gynecologic cancer surgery.

METHODS

This is a prospective cohort study at an academic gynecological cancer center from Oct 2015 through Jan 2017. We applied systematically numerous screening tools, geriatric questionnaires and single measurements which may provide predictions for surgical outcomes. We classified frailty according to the Fried definition and surgical complications were graded according Clavien-Dindo criteria. Using logistic regression analysis, we identified predictive clinical variables for postoperative complications (POC).

RESULTS

Overall 226 patients were enrolled (median age 59 years, range 18-87 years). The prevalence of frailty based on the presence of three or more frailty criteria was 14.2%, the presence of one or two frailty criteria was classified as prefrail with 59.4% and without any presence as robust with 26.5%. Within 30 days of surgery, nine (3.8%) patients have died and 40 (18.3%) experienced a grade ≥ IIIb complication. In the regression analysis obesity (OR: 5.37, 95% CI 1.99-14.49, p = 0.001) as well as ECOG >1 (OR: 4.32, 95% CI 1.28-1.55, p = 0.018) and Albumin<3.6 g/dl (OR: 3.88, 95% CI 1.37-10.98, p = 0.011) emerged as significant predictors of postoperative complications (POC). Fried Frailty Score (OR: 2.41, 95% CI 0.91-6.41, p = 0.077) showed no significant additional predictive value.

CONCLUSION

Fried Frailty Score could help the surgeon to estimate the risk for POC among patients undergoing gynecologic cancer surgery. But preoperatively determined ECOG, BMI and Albumin can predict severe POC in patients undergoing gynecologic surgery more precisely and should be assessed routinely.

Sex Differences in Frail Older Adults with Foot Pain in a Spanish Population: An Observational Study

Frailty is a condition that can increase the risk of falls. In addition, foot pain can influence older adults and affect their frail condition. The main objective was to measure the frailty degree in older adults in a Spanish population with foot pain from moderate to severe.

METHOD

This is a cross-sectional descriptive study. A sample of people older than 60 years (n = 52), including 26 males and 26 females, were recruited, and frailty disability was measured using the 5-Frailty scale and the Edmonton Frailty scale (EFS).

RESULTS

Spearman's correlation coefficients were categorized as weak (rs ≤ 0.40), moderate (0.41 ≤ rs ≥ 0.69), or strong (0.70 ≤ rs ≥ 1.00). There was a statistically significant correlation for the total score (p < 0.001) and most of the subscales of the 5-Frailty scale compared with the EFS, except for Mood (p > 0.05). In addition, females and males showed similar 5-Frailty and Edmonton Frail scales scores with no difference (p > 0.05).

CONCLUSION

Foot pain above 5 points, i.e., from moderate to severe, does not affect the fragility more in one sex than another.

FRAIL scale: Predictive validity and diagnostic test accuracy

OBJECTIVE

To examine the predictive validity of the FRAIL scale for mortality, and diagnostic test accuracy (DTA) against the frailty phenotype (FP).

MEASUREMENT

Frailty was measured in 846 community-dwelling adults (mean age 74.3 [SD 6.3] years, 54.8% female) using a modified FRAIL scale and modified FP. Mortality was matched to death records.

RESULTS

The FRAIL scale demonstrated significant predictive validity for mortality up to 10 years (Frail adjHR: 2.60, P < .001). DTA findings were acceptable for specificity (86.8%) and Youden index (0.50), but not sensitivity (63.6%), or area under the receiver operator curve (auROC) (0.75). DTA estimates were more acceptable when a cut-point of ≥2 characteristics was used rather than ≥3 in the primary DTA analysis.

CONCLUSION

The FRAIL scale is a valid predictor of mortality. DTA estimates depend on FRAIL scale cut-point used. This instrument is a potentially useful frailty screening tool.

Frailty Assessment in Community-Dwelling Older Adults: A Comparison of 3 Diagnostic Instruments

OBJECTIVES

Compare the diagnostic performance of FRAIL against Fried Phenotype and Frailty Index (FI), and identify clinical factors associated with pre-frailty/frailty.

DESIGN

Cross-sectional analysis.

SETTING

Community-based screenings in Senior Activity Centres, Residents' Corners and Community Centres in northeast Singapore.

PARTICIPANTS

517 community dwelling participants aged >55 years and ambulant independently (with/ without walking aids) were included in this study. Residents of sheltered or nursing homes, and seniors unable to ambulate at least four meters independently were excluded.

MEASUREMENTS

The multidomain geriatric screen included assessments for social vulnerability, mood, cognition, sarcopenia and nutrition. Participants completed a battery of physical fitness tests for grip strength, gait speed, lower limb strength and power, flexibility, balance and endurance, with overall physical performance represented by Short Physical Performance Battery (SPPB). Frailty status was assigned on FRAIL, Fried and 35-item FI.

RESULTS

Prevalence of frailty was 1.3% (FRAIL) to 3.1% (FI). Pre-frailty prevalence ranged from 17.0% (FRAIL) to 51.2% (FI). FRAIL demonstrated poor agreement with FI (kappa=0.171, p<0.0001), and Fried (kappa=0.194, p<0.0001). A lower FRAIL cut-off ≥1 yielded significantly improved AUC of 0.70 (95%CI 0.55 to 0.86, p=0.009) against Fried, and 0.71 (95%CI 0.55 to 0.86, p=0.008) against FI. All 3 frailty measures were diagnostic of impaired physical performance on SPPB, with AUCs ranging from 0.69 on FRAIL to 0.77 on Fried (all p values <0.01). Prevalence of low socio-economic status, depression, malnutrition and sarcopenia increased significantly, while fitness measures of gait speed, balance, and endurance declined progressively across robust, pre-frail and frail on all 3 frailty instruments (p <0.05).

CONCLUSIONS

Our results suggest that different frailty instruments may capture over-lapping albeit distinct constructs, and thus may not be used interchangeably. FRAIL has utility for quick screening, and any positive response should trigger further assessment, including evaluation for depression, social vulnerability and malnutrition.

Inter-relationships between Gender, Frailty and 10-Year Survival in Older Italian Adults: an observational longitudinal study

Aim of the present study was to assess the impact of gender on the relationship between long-term mortality and clinical frailty. In an observational, longitudinal study on 10-year mortality, we examined 1284 subjects. The Frailty Staging System was used to assess frailty. The Cox model was employed to assess variables independently associated with survival using a backward stepwise algorithm. To investigate the possible interactions between gender and the selected variables, an extension of the multivariable fractional polynomial algorithm was adopted. Women were more likely to be older, have a higher disability, present with more comorbidities, consume more drugs, be frail and have a higher rate of survival at the follow-up than were men. At the Cox multivariate analysis only age (HR 2.26), female gender (HR 0.43), and number of drugs (HR 1.57) were significant and independent factors associated with all-cause mortality. In the survival analyses, only frailty (vs no frailty) showed significant interaction with gender (p < 0.001, HR = 1.92). While the presence of frailty reduced the survival rate in women, no effect was observed in men. Importantly, frail women showed higher survival rates than did both frail and no frail men. The main finding of the present study is that gender shapes up the association between frailty and long-term survival rates.

Description of frail older people profiles according to four screening tools applied in primary care settings: a cross sectional analysis

Background

Regarding the health care of older populations, WHO recommends shifting from disease-driven attention models towards a personalized, integrated and continuous care aimed to the maintenance and enhancement of functional capacities. Impairments in the construct of functional intrinsic capacity have been understood as the condition of frailty or vulnerability. No consensus has been yet reached regarding which tools are the most suitable for screening this kind of patients in primary care settings. Tools based on the measurement of functional performance such as Timed up and go test (TUG), Short Physical Performance battery (SPPB), self-completed questionnaires like Tilburg Frailty Indicator (TFI) and clinical judgement, as the Gerontopole Frailty Scale (GFS) may be adequate. The objective of this work is to describe and compare characteristics of community-dwelling individuals identified as vulnerable or frail by four tools applied in primary care settings.

Methods

Cross sectional analysis developed in primary care services in two regions of Spain.

Community-dwelling independent individuals aged 70 or more willing to participate were recruited and data was collected via face-to-face interviews. Frailty was assessed by TUG, SPPB, TFI and GFST. Also socio-demographic characteristics, lifestyle habits and health status data (comorbidities, polypharmacy, self-perceived health), were collected. Multiple correspondence analysis (MCA) and cluster analysis were used to identify groups of individuals with similar characteristics.

Results

Eight hundred sixty-five individuals were recruited, 53% women, with a mean age of 78 years. Four clusters of participants emerge. Cluster 1 (N = 263) contained patients categorized as robust by most of the studied tools, whereas clusters 2 (N = 199), 3 (N = 183) and 4 (N = 220) grouped patients classified as frail or vulnerable by at least one of the tools. Significant differences were found between clusters.

Conclusions

The assessed tools identify different profiles of patients according to their theoretical construct of frailty. There is a group of patients that are identified by TUG and SPPB but not by GFS or TFI. These tools may be useful in primary care settings for the implementation of a function- driven clinical care of older patients.

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.

Predictive Accuracy of Frailty Tools for Adverse Outcomes in a Cohort of Adults 80 Years and Older: A Decision Curve Analysis

OBJECTIVES

To compare the predictive performance of 3 frailty identification tools for mortality, hospitalization, and functional decline in adults aged ≥80 years using risk reclassification statistics and decision curve analysis.

DESIGN

Population-based, prospective cohort.

SETTING

BELFRAIL study, Belgium.

PARTICIPANTS

560 community-dwelling adults aged ≥80 years.

MEASUREMENTS

Frailty by Cardiovascular Health Study (CHS) phenotype, Longitudinal Aging Study Amsterdam (LASA) markers, and Groeningen Frailty Indicator (GFI); mortality until 5.1 ± 0.25 years from baseline and hospitalization until 3.0 ± 0.25 years; and functional status assessed by activities of daily living at baseline and after 1.7 ± 0.21 years.

RESULTS

Frailty prevalence was 7.3% by CHS phenotype, 21.6% by LASA markers, and 22% by GFI. Participants determined to be frail by each tool had a significantly higher risk for all-cause mortality and first hospitalization. For functional decline, only frail by GFI had a higher adjusted odds ratio. Harrell 's C-statistic for mortality and hospitalization and area under receiver operating characteristic curve for functional decline were similar for all tools and <0.70. Reclassification statistics showed improvement only by LASA markers for hospitalization and mortality. In decision curve analysis, all tools had higher net benefit than the 2 default strategies of "treat all" and "treat none" for mortality risk ≥20%, hospitalization risk ≥35%, and functional decline probability ≥10%, but their curves overlapped across all relevant risk thresholds for these outcomes.

CONCLUSIONS AND IMPLICATIONS

In a cohort of adults aged ≥80 years, 3 frailty tools based on different conceptualizations and assessment sources had comparable but unsatisfactory discrimination for predicting mortality, hospitalization, and functional decline. All showed clinical utility for predicting these outcomes over relevant risk thresholds, but none was significantly superior. Future research on frailty tools should include a focus on the specific group of adults aged ≥80 years, and the predictive accuracy for adverse outcomes of different tools needs a comprehensive assessment that includes decision curve analysis.

Association between non-invasive liver fibrosis scores and occurrence of health adverse outcomes in older people

BACKGROUND

The relation between liver fibrosis scores and health outcomes in older people has been barely investigated. We aimed to evaluate the association of four liver fibrosis scores (fibrosis-4 -FIB-4-, NAFLD fibrosis score -NFS-, BARD and aspartate aminotransferase/alanine aminotransferase ratio -AST/ALT-) with mortality and incident disability at 6 years in an older population.

METHODS

We studied 962 individuals aged ≥65 (mean age 74.4; female 55.5%) with a mean follow-up of 95.7 months, enrolled in the InCHIANTI study. The relationship between liver fibrosis scores and mortality and disability was assessed through Cox and log-binomial regressions.

RESULTS

NFS and FIB-4 were associated with higher overall (aHR ranging 1.38-1.78 for intermediate risk of fibrosis and 1.60-2.02 for high risk) and cardiovascular (aHR ranging 1.76-2.90 for intermediate and 2.22-2.42 for high risk) mortality. AST/ALT and BARD were only associated with overall mortality. Only NFS and FIB-4 high risk classes were associated with incident disability (aRR ranging 1.93-2.76). Despite poor sensitivity, all scores showed high specificity (ranging 0.88-0.95).

CONCLUSION

Higher risk of liver fibrosis is associated with higher risk of poor health outcomes. Liver fibrosis scores may help to stratify the risk and, mainly, identify elderly patients with favorable prognosis.

If my muscle could talk: Myokines as a biomarker of frailty

Frailty is a potentially reversible state of increased vulnerability to negative health-related outcomes that occurs as a result of multisystem biological impairment and environmental aspects. Given the relevance of this condition in both clinics and research, biomarkers of frailty have been actively sought after. Although several candidate biomarkers of frailty have been identified, none of them has yet been incorporated in the assessment or monitoring of the condition. Over the last years, increasing research interest has been focused on myokines, a set of cytokines, small proteins and proteoglycan peptides that are synthetized, expressed and released by skeletal myocytes in response to muscular contractions. Myokines may act in autocrine, paracrine, and endocrine manner and regulate several processes associated with physical frailty, including muscle wasting, dynapenia, and slowness. This review discusses the rationale to support the use of myokines as biomarkers of frailty in older adults.

Frailty and functional outcomes after open and endovascular procedures for patients with peripheral arterial disease: A systematic review

BACKGROUND

Frailty has been associated with postoperative complications and mortality across surgical specialties, including vascular surgery. However, the influence of frailty on postoperative functional outcomes is unclear. We sought to determine the influence of frailty on functional outcomes after open or endovascular vascular procedures in patients with peripheral arterial disease.

METHODS

This systematic review was conducted according to the PRISMA guidelines. Eligible articles were identified through database searches of Pubmed and EMBASE in April 2017. Studies reporting on frailty and functional outcomes after vascular interventions for peripheral artery disease (PAD) were included. Outcomes of interest were dependency in activities of daily living (ADL), dependent mobility, discharge destination, disability-free survival, and quality of life. Individual studies were assessed for quality and risk of bias using the Quality in Prognosis Studies tool.

RESULTS

Eight studies met the eligibility criteria and were included. The risk of bias was low in two studies, intermediate in three studies, and high in three studies. Methods for frailty assessment were different for each study. Frailty was a predictor for discharge to a higher level of care, dependent mobility, and dependency in ADL after vascular procedures for PAD. Both frailty models and individual frailty characteristics seem to be associated with these adverse functional outcomes.

CONCLUSIONS

Despite a limited amount of literature and an overall intermediate quality of the included studies, this systematic review shows an association between frailty and adverse functional outcomes after peripheral arterial procedures for PAD, including discharge to a care facility, dependent mobility, and a decline in ADL functioning.

What are the most effective interventions to improve physical performance in pre-frail and frail adults? A systematic review of randomised control trials

BACKGROUND

With life expectancy continuing to rise in the United Kingdom there is an increasing public health focus on the maintenance of physical independence among all older adults. Identifying interventions that improve physical outcomes in pre-frail and frail older adults is imperative.

METHODS

A systematic review of the literature 2000 to 2017 following PRISMA guidelines and registered with PROSPERO (no. CRD42016045325).

RESULTS

Ten RCT trials fulfilled selection criteria and quality appraisal. The study quality was moderate to good. Interventions included physical activity; nutrition, physical activity combined with nutrition. Interventions that incorporated one or more physical activity components significantly improved physical outcomes in pre-frail and/or frail older adults.

CONCLUSIONS

Physical activity interventions are key to maintaining independence in pre-frail and frail older adults. A lack of consensus regarding the definition of frailty, and an absence of core measures to assess this means any attempt to create an optimal intervention will be impeded. This absence may ultimately impact on the ability of older and frail adults to live well and for longer in the community.

Instruments for the detection of frailty syndrome in older adults: A systematic review

Frailty is a dynamic process in which there is a reduction in the physical, psychological and/or social function associated with aging. The aim of this study was to identify instruments for the detection of frailty in older adults, characterizing their components, application scenarios, ability to identify pre-frailty and clinimetric properties evaluated. The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), under registration number CRD42017039318. A total of 14 electronic sources were searched to identify studies that investigated instruments for the detection of frailty or that presented the construction and/or clinimetric evaluation of the instrument, according to criteria established by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). 96 studies were included in the qualitative synthesis: 51 instruments for the detection of frailty were identified, with predominantly physical domains; 40 were constructed and/or validated for use in the older adult community population, 28 only highlighted the distinction between frail and non-frail individuals and 23 presented three or more levels of frailty. The FRAGIRE, FRAIL Scale, Edmonton Frail Scale and IVCF-20 instruments were the most frequently analyzed in relation to clinimetric properties. It was concluded that: (I) there is a large number of instruments for measuring the same construct, which makes it difficult for researchers and clinicians to choose the most appropriate; (II) the FRAGIRE and CFAI stand out due to their multidimensional aspects, including an environmental assessment; however, (III) the need for standardization of the scales was identified, since the use of different instruments in clinical trials may prevent the comparability of the results in systematic reviews and; (IV) considering the different instruments identified in this review, the choice of researchers/clinicians should be guided by the issues related to the translation and validation for their location and the suitability for their context.

Obesity, Dietary inflammation, and Frailty among Older Adults: Evidence from the National Health and Nutrition Examination Survey

Knowledge related to the relationship between obesity and frailty is limited. This study aimed to investigate associations between obesity, dietary inflammation, and frailty among older adults. Study data came from National Health and Nutrition Examination Survey (2007-2014) examinations of adults age ≥60 years (n = 7182). Dietary inflammatory potential was determined using the Dietary Inflammatory Index (DII^®) derived from 24-h dietary recall. We analyzed independent and joint associations of obesity and DII with frailty to evaluate interaction. Multivariable logistic regression revealed that both obesity (Odds Ratio [OR] = 2.24, 95% CI: 1.68, 2.99) and moderately pro-inflammatory DII (OR = 1.68, 95% CI: 1.10, 2.58) were independently associated with greater frailty prevalence. A negative multiplicative interaction between obesity and highest pro-inflammatory diet also was found (adjusted odds in non-obese and obese were 2.07 and 2.37, respectively; p = 0.046). Results indicate the importance of considering obesity and dietary inflammatory potential when screening for frailty or developing treatments.

[Prevalence and profile of the frail population in La Palma, Canary Islands]

INTRODUCTION

Population ageing requires that health and social systems focus their attention on identifying frailty in the elderly. In the Canary Islands, there are no studies to determine the prevalence of frailty among its population. The objective of this study is to determine the prevalence and profile of frailty in the island of La Palma, Canary Islands, Spain.

MATERIAL AND METHOD

A cross-sectional study was conducted to estimate the prevalence and the profile of frailty. The sample were residents over 70 years old, valued by the Fried criteria, and taking into account other related factors. The prevalence is offered with a confidence interval of 95% and is compared with that of other Spanish populations. To determine the profile, a simple comparison of variables was made, followed by using them in logistic regression models. All the tests were bilateral at a P≤0.05 level.

RESULTS

The prevalence of frailty in people over 70 years was estimated at 20% (17-23%). This prevalence shows differences with those of other Spanish populations. The factors that showed a relationship with frailty were, being female, widowed, living alone, low physical activity, cognitive impairment, depression, polymedication, and adverse clinical history. Multivariate analysis identifies factors associated with the frailty variables related to marital status, co-existence, polypharmacy, depressive states, and lack of physical exercise.

CONCLUSIONS

The elderly population of La Palma have greater frailty compared to that described in other regions of Spain, with their profile being that of a widowed person, with depression, polymedicated, living alone, and not exercising.

The ability of four frailty screening instruments to predict mortality, hospitalization and dependency in (instrumental) activities of daily living

The aim of this study was to assess the predictive ability of the frailty phenotype (FP), Groningen Frailty Indicator (GFI), Tilburg Frailty Indicator (TFI) and frailty index (FI) for the outcomes mortality, hospitalization and increase in dependency in (instrumental) activities of daily living ((I)ADL) among older persons. This prospective cohort study with 2-year follow-up included 2420 Dutch community-dwelling older people (65+, mean age 76.3 ± 6.6 years, 39.5% male) who were pre-frail or frail according to the FP. Mortality data were obtained from Statistics Netherlands. All other data were self-reported. Area under the receiver operating characteristic curves (AUC) was calculated for each frailty instrument and outcome measure. The prevalence of frailty, sensitivity and specificity were calculated using cutoff values proposed by the developers and cutoff values one above and one below the proposed ones (0.05 for FI). All frailty instruments poorly predicted mortality, hospitalization and (I)ADL dependency (AUCs between 0.62–0.65, 0.59–0.63 and 0.60–0.64, respectively). Prevalence estimates of frailty in this population varied between 22.2% (FP) and 64.8% (TFI). The FP and FI showed higher levels of specificity, whereas sensitivity was higher for the GFI and TFI. Using a different cutoff point considerably changed the prevalence, sensitivity and specificity. In conclusion, the predictive ability of the FP, GFI, TFI and FI was poor for all outcomes in a population of pre-frail and frail community-dwelling older people. The FP and the FI showed higher values of specificity, whereas sensitivity was higher for the GFI and TFI.

Predictive Capacity of Frailty Phenotype Toward Patterns of Disability Identified Using Latent Class Analysis

OBJECTIVES

Frailty phenotype (FP) has low sensitivity toward the identification of older people who will lose 1 or more activities of daily living. Nevertheless, the definition of disability in terms of activities of daily living may not resemble the pattern of functional impairment occurring during aging. The aim of this study was to examine the discriminative capacity of the FP toward the identification of patterns of disabilities in an extended list of tasks, identified among community-dwelling older people.

DESIGN

Longitudinal cohort study.

SETTING AND PARTICIPANTS

We included 997 persons age 65 years and older selected from the Invecchiare in Chianti (InCHIANTI) Study population.

MEASURES

Using latent class analysis, we assessed the pattern of 3-year changes in 24 functional tasks. Then, we calculated the discriminative capacity of the FP for each pattern of disability. Analyses were stratified by sex.

RESULTS

In both men and women, we recognized 3 classes: stable function; disability in complex tasks; and global functional disability. Among women, ability of FP to identify persons in global functional disability showed sensitivity = 0.42, specificity = 0.98, positive and negative predictive values 0.75 and 0.91; the corresponding values for prediction of disability in complex tasks were 0.13, 0.98, 0.68, and 0.75. Similar results were obtained among men.

CONCLUSIONS/IMPLICATIONS

Over 3 years, older people of the InCHIANTI population remained largely functional stable, some persons developed deficiency in complex tasks, and a minority developed global functional disability. Trying to predict these 3 patterns may be useful for the care of older people in order to promote individualized interventions to reduce the burden of disabilities and their consequences. To this purpose, FP showed a fairly good capacity to identify people at risk of functional decline, but further studies are needed to identify instruments with better prognostic capacity.

Development of a cardiac-centered frailty ontology

BACKGROUND

A Cardiac-centered Frailty Ontology can be an important foundation for using NLP to assess patient frailty. Frailty is an important consideration when making patient treatment decisions, particularly in older adults, those with a cardiac diagnosis, or when major surgery is a consideration. Clinicians often report patient's frailty in progress notes and other documentation. Frailty is recorded in many different ways in patient records and many different validated frailty-measuring instruments are available, with little consistency across instruments. We specifically explored concepts relevant to decisions regarding cardiac interventions. We based our work on text found in a large corpus of clinical notes from the Department of Veterans Affairs (VA) national Electronic Health Record (EHR) database.

RESULTS

The full ontology has 156 concepts, with 246 terms. It includes 86 concepts we expect to find in clinical documents, with 12 qualifier values. The remaining 58 concepts represent hierarchical groups (e.g., physical function findings). Our top-level class is clinical finding, which has children clinical history finding, instrument finding, and physical examination finding, reflecting the OGMS definition of clinical finding. Instrument finding is any score found for the existing frailty instruments. Within our ontology, we used SNOMED-CT concepts where possible. Some of the 86 concepts we expect to find in clinical documents are associated with the properties like ability interpretation. The concept ability to walk can either be able, assisted or unable. Each concept-property level pairing gets a different frailty score. Each scored concept received three scores: a frailty score, a relevance to cardiac decisions score, and a likelihood of resolving after the recommended intervention score. The ontology includes the relationship between scores from ten frailty instruments and frailty as assessed using ontology concepts. It also included rules for mapping ontology elements to instrument items for three common frailty assessment instruments. Ontology elements are used in two clinical NLP systems.

CONCLUSIONS

We developed and validated a Cardiac-centered Frailty Ontology, which is a machine-interoperable description of frailty that reflects all the areas that clinicians consider when deciding which cardiac intervention will best serve the patient as well as frailty indications generally relevant to medical decisions. The ontology owl file is available on Bioportal at http://bioportal.bioontology.org/ontologies/CCFO .

Multicomponent Frailty Assessment Tools for Older People with Psychiatric Disorders: A Systematic Review

OBJECTIVE

To review evidence evaluating the use of multicomponent frailty assessment tools in assessing frailty in older adults with psychiatric disorders.

METHODS

A systematic literature review was conducted to identify all multicomponent frailty assessment tools (ie, a tool that assesses two or more indicators of frailty). The items of each frailty assessment tool were compared with Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) diagnostic criteria for psychiatric disorders to assess construct overlap. Studies conducted in community, inpatient, and outpatient clinical settings were considered for inclusion.

PARTICIPANTS

Adults aged 60 years or older.

RESULTS

A total of 5639 records were identified following the removal of duplicates, from which 95 studies were included for review. Of the 48 multicomponent frailty assessment tools identified, no tool had been developed for, or validated in, older adult populations with a psychiatric disorder. Overall, 20 of 48 frailty assessment tools contained a psychological assessment domain, with 17 of 48 tools citing the presence of depressed mood and/or anxiety as a frailty indicator. Common areas of construct overlap in frailty assessment tools and DSM-5 diagnostic criteria included weight loss (29 of 48) and fatigue (21 of 48).

CONCLUSIONS

Significant construct overlap exists between the indicators of frailty as conceptualized in existing frailty assessment tools and DSM-5 diagnostic criteria for common psychiatric disorders including major depressive episode and generalized anxiety disorder that has the potential to confound frailty assessment results. Further research is necessary to establish a reliable and valid tool to assess frailty in this population. J Am Geriatr Soc 67:1085-1095, 2019.

Frailty in surgical patients

OBJECTIVE

To describe the current definitions, aetiology, assessment tools and clinical implications of frailty in modern surgical practice.

BACKGROUND

Frailty is a critical issue in modern surgical practice due to its association with adverse health events and poor post-operative outcomes. The global population is rapidly ageing resulting in more older patients presenting for surgery. With this, the number of frail patients presenting for surgery is also increasing. Despite the identification of frailty as a significant predictor of poor health outcomes, there is currently no consensus on how to define, measure and diagnose this important syndrome.

METHODS

Relevant references were identified through keyword searches of the Cochran, MEDLINE and EMbase databases.

RESULTS

Despite the lack of a gold standard operational definition, frailty can be conceptualised as a state of increased vulnerability resulting from a decline in physiological reserve and function across multiple organ systems, such that the ability to withstand stressors is impaired. Multiple studies have shown a strong association between frailty and adverse peri-operative outcomes. Frailty may be assessed using multiple tools; however, the ideal tool for use in a clinical setting has yet to be identified. Despite the association between frailty and adverse outcomes, few interventions have been shown to improve outcomes in these patients.

CONCLUSION

Frailty encompasses a group of individuals at high risk of adverse post-operative outcomes. Further work exploring ways to optimally assess and target interventions towards these patients should be the focus of ongoing research.

Frailty Index associates with GRIN2B in two representative samples from the United States and the United Kingdom

The concept of frailty has been used in the clinical and research field for more than two decades. It is usually described as a clinical state of heightened vulnerability to poor resolution of homeostasis after a stressor event, which thereby increases the risk of adverse outcomes, including falls, delirium, disability and mortality. Here we report the results of the first genome-wide association scan and comparative gene ontology analyses where we aimed to identify genes and pathways associated with the deficit model of frailty. We used a discovery-replication design with two independent, nationally representative samples of older adults. The square-root transformed Frailty Index (FI) was the outcome variable, and age and sex were included as covariates. We report one hit exceeding genome-wide significance: the rs6765037 A allele was significantly associated with a decrease in the square-root transformed FI score in the Discovery sample (beta = -0.01958, p = 2.14E-08), without confirmation in the Replication sample. We also report a nominal replication: the rs7134291 A allele was significantly associated with a decrease in the square-root transformed FI score (Discovery sample: beta = -0.01021, p = 1.85E-06, Replication sample: beta = -0.005013, p = 0.03433). These hits represent the KBTBD12 and the GRIN2B genes, respectively. Comparative gene ontology analysis identified the pathways ‘Neuropathic pain signalling in dorsal horn neurons’ and the ‘GPCR-Mediated Nutrient Sensing in Enteroendocrine Cells’, exceeding the p = 0.01 significance in both samples, although this result does not survive correction for multiple testing. Considering the crucial role of GRIN2B in brain development, synaptic plasticity and cognition, this gene appears to be a potential candidate to play a role in frailty. In conclusion, we conducted genome-wide association scan and pathway analyses and have identified genes and pathways with potential roles in frailty. However, frailty is a complex condition. Therefore, further research is required to confirm our results and more thoroughly identify relevant biological mechanisms.

The added value of health indicators to mortality predictions in old age: A systematic review

BACKGROUND

Numerous risk prediction models use indicators of health to predict mortality in old age. The added value to mortality predictions based on demographic variables is unknown.

OBJECTIVE

To evaluate the accuracy of health indicators in predicting all-cause mortality among individuals aged 50+ using area under receiver operating characteristic curve (AUC). Specifically, to assess the added value of health indicators relative to demographic variables.

METHODS

We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. There were no restrictions on study designs, follow-up duration, language, or publication dates. We also examined the quality of studies using the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies.

RESULTS

Out of 804 studies investigating all-cause mortality in older persons, 16 studies were eligible. In community-dwelling populations, the accuracy of demographic variables and health indicators combined ranged from AUC 0.71 to 0.82, indicating modest ability to predict mortality. Age contributed the most to mortality prediction (AUC 0.65 to 0.78) and compared to age and sex, the added values of genetics, physiology, functioning, mood, cognition, nutritional status, subjective health, disease, frailty, and lifestyle ranged from AUC 0.01 to 0.10. The lack of validation samples made it difficult to assess their true added value. Findings were similar in institutionalized populations. Heterogeneity of the studies prevented us from performing a meta-analysis.

CONCLUSION

Age and sex contributed the most to mortality predictions in old age while the added value of health indicators is likely to be limited.

Association Between Age and Patient-Reported Changes in Voice and Swallowing After Thyroidectomy

OBJECTIVES

Despite intact recurrent laryngeal nerves, patient-reported voice and swallowing changes are common after thyroidectomy. The association between patient age or frailty status and these changes is unknown. The aim of this study was to evaluate the impact of age and frailty on the incidence of voice and swallowing alterations after thyroidectomy.

METHODS

We performed an institutional review board (IRB)-approved retrospective review of consecutive patients who underwent total thyroidectomy with intraoperative recurrent laryngeal nerve (RLN) monitoring at a single institution between January 2014 and September 2016. Patients with RLN injury were excluded. After data extraction, a modified frailty index (mFI) was calculated for each patient. The association among risk factors, including age, mFI, prior history of neck surgery, frequent voice use, presence of malignancy or gastroesophageal reflux disease, and smoking status and reported voice and/or swallowing changes was examined.

RESULTS

Of 924 patients undergoing thyroidectomy, 148 (16.0%) reported only changes in voice; 52 (5.6%) reported only difficulty in swallowing; and 26 (2.8%) reported changes with both voice and swallowing. On multivariate analysis, we found a significant increase in voice or swallowing alterations up to the age of 50 years (5% increased odds per year), after which these changes plateaued. We found that mFI was not associated with voice or swallowing changes.

CONCLUSION

Age ≥ 50 years is independently associated with the development of voice or swallowing changes after thyroidectomy, despite intact RLN. Additional prospective studies are needed to validate these findings, further define this association, and identify risk factors for developing these changes.

Randomized controlled trial to evaluate a prevention program for frail community-dwelling older adults: a D-SCOPE protocol

BACKGROUND

Frail community-dwelling older adults, whom might experience problems regarding physical, cognitive, psychological, social and environmental factors, are at risk for adverse outcomes such as disability, institutionalization and mortality. People in need of help do not always find their way to care and support services and are left undetected. The aim of the D-SCOPE project is to detect frail community-dwelling older adults who previously went unnoticed and to improve their access to care and support. Goal is to increase their frailty-balance, quality of life, meaning in life, life satisfaction, mastery, community inclusion and ageing well in place.

METHODS/DESIGN

The study is a prospective, longitudinal randomized four-armed controlled trial with follow-up at 6 months. The study group aims to include 900 community-dwelling older adults aged 60 years and over from 3 municipalities in Flanders (Belgium). While selecting the study group, risk profiles for frailty will be taken into account. Participants will be randomly selected from the census records in each municipality. Data will be collected prospectively at baseline (T0) and at follow-up, 6 months after baseline (T1). At baseline, participants who are at least mild frail on one of the 5 domains of frailty (CFAI-plus) or feel frail based on the subjective assessment of frailty will be randomly assigned to (1) the study group or (2) the control group. A mixed method design with the inclusion of quantitative and qualitative data analyses will be used to evaluate the efficacy and experiences of the detection and prevention program on frailty.

DISCUSSION

The study will contribute to an innovative vision concerning the organization of care and support, and a timely and accurate detection and support of community-dwelling older adults at risk for frailty.
