Frailty as a Predictor of Future Falls Among Community-Dwelling Older People: A Systematic Review and Meta-Analysis

Is proactive frailty identification a good idea? A qualitative interview study

Background

In England, GPs are independent contractors working to a national contract. Since 2017, the contract requires GPs to use electronic tools to proactively identify moderate and severe frailty in people aged ≥65 years, and offer interventions to help those identified to stay well and maintain independent living. Little is currently known about GPs’ views of this contractual requirement.

Aim

To explore GPs’ views of identifying frailty and offering interventions for those living with moderate or severe frailty.

Design and setting

A sequential mixed-methods study of GPs in the East Midlands region of England — namely Derbyshire, Leicestershire, Lincolnshire, Nottinghamshire, and Northamptonshire — undertaken between January and May 2019.

Method

GPs were made aware of the study via professional organisations’ newsletters and bulletins, GP email lists, and social media, and were invited to complete an online questionnaire. Responses were analysed using descriptive statistics and, based on those survey responses, GPs with a range of GP and practice characteristics, as well as views on identifying frailty, were selected to participate in a semi-structured telephone interview. Interview transcripts were analysed using framework analysis.

Results

In total, 188 out of 3058 (6.1%) GPs responded to the survey and 18 GPs were interviewed. GPs were broadly supportive of identifying frailty, but felt risk-stratification tools lacked sensitivity and specificity, and wanted evidence showing clinical benefit. Frailty identification increased workload and was under-resourced, with limited time for, and access to, necessary interventions. GPs felt they lacked knowledge about frailty and more education was required to better understand it.

Conclusion

Proactively identifying and responding to frailty in primary care requires GP education, highly sensitive and specific risk-stratification tools, better access to interventions to lessen the impact of frailty, and adequate resourcing to achieve potential clinical impact.

Geriatric screening, fall characteristics and 3- and 12 months adverse outcomes in older patients visiting the emergency department with a fall

BACKGROUND

Falls in older Emergency Department (ED) patients may indicate underlying frailty. Geriatric follow-up might help improve outcomes in addition to managing the direct cause and consequence of the fall. We aimed to study whether fall characteristics and the result of geriatric screening in the ED are independently related to adverse outcomes in older patients with fall-related ED visits.

METHODS

This was a secondary analysis of the observational multicenter Acutely Presenting Older Patient (APOP) study, of which a subset of patients aged ≥70 years with fall-related ED visits were prospectively included in EDs of two Dutch hospitals. Fall characteristics (cause and location) were retrospectively collected. The APOP-screener was used as a geriatric screening tool. The outcome was 3- and 12-months functional decline and mortality. We assessed to what extent fall characteristics and the geriatric screening result were independent predictors of the outcome, using multivariable logistic regression analysis.

RESULTS

We included 393 patients (median age 80 (IQR 76-86) years) of whom 23.0% were high risk according to screening. The cause of the fall was extrinsic (49.6%), intrinsic (29.3%), unexplained (6.4%) or missing (14.8%). A high risk geriatric screening result was related to increased risk of adverse outcomes (3-months adjusted odds ratio (AOR) 2.27 (1.29-3.98), 12-months AOR 2.20 (1.25-3.89)). Independent of geriatric screening result, an intrinsic cause of the fall increased the risk of 3-months adverse outcomes (AOR 1.92 (1.13-3.26)) and a fall indoors increased the risk of 3-months (AOR 2.14 (1.22-3.74)) and 12-months adverse outcomes (AOR 1.78 (1.03-3.10)).

CONCLUSIONS

A high risk geriatric screening result and fall characteristics were both independently associated with adverse outcomes in older ED patients, suggesting that information on both should be evaluated to guide follow-up geriatric assessment and interventions in clinical care.

The balance function is associated with frailty in community-dwelling older women

Conditions underlying balance impairment should be identified to improve knowledge regarding clinical interventions for frail older adults. This study aims to explore the relationship between balance functions and frailty by using the brief balance evaluation systems test (BESTest), which can assess biomechanical constraints, stability limits/verticality, anticipatory postural adjustments (APAs), reactive postural responses, sensory orientation and stability in gait. A total of 75 community-dwelling older women were included in this cross-sectional study. We evaluated frailty by using the Kihon checklist and assessed the participants' balance functions by using the Brief BESTest. We performed the Mann-Whitney U test and receiver operating characteristic curve analysis to compare each balance function between frail and nonfrail participants. Twenty-two of the 75 (29.3%) participants were included in the frailty group. We noted significant differences between the frailty and nonfrailty groups with regard to stability limit, APAs, sensory orientation, and stability in gait (P = 0.010, 0.001, 0.008 and <0.001, respectively). In terms of determining frailty and nonfrailty, APAs and stability in gait were moderately accurate (the area under the curve = 0.730 and 0.713, respectively). APAs showed the highest sensitivity (0.864), whereas stability limits, sensory orientation, and stability in gait showed the highest specificity (0.943, 0.849 and 0.868, respectively). Thus, frail and nonfrail older adults showed significantly different balance functions, such as stability limits, APAs, sensory orientation and stability in gait. The Brief BESTest is useful for evaluating balance functions in relation to frailty.

The association between injurious falls and older adults' cognitive function: the role of depressive mood and physical performance

Background

The impact of falls on cognitive function is unclear. We explored whether injurious falls are associated with cognitive decline in older adults, and evaluated the role of changes in psychological and physical health as mediators of such association.

Methods

This prospective study involved 2267 community-dwelling participants in the Swedish National study on Aging and Care in Kungsholmen (≥60 years). Data on injurious falls (ie, falls requiring medical attention) during each 3-year time interval of follow-up were obtained from national registers. Assessment of cognitive function (Mini-Mental State Examination), depressive mood (Montgomery-Åsberg Depression Rating Scale), and physical performance (walking speed) were carried out every 3 or 6 years over a 12-year follow-up. The association between falls and cognition was estimated through linear mixed-effects models, and the mediating role of changes in depressive mood and physical performance was tested using mediation analysis.

Results

After adjusting for potential confounders, individuals who experienced injurious falls had a greater annual decline in Mini-Mental State Examination in the subsequent time interval (β = −1.49, 95% CI: −1.84; −1.13), than those who did not. The association increased with the occurrence of ≥2 falls (β = −2.13, 95% CI: −2.70; −1.56). Worsening of walking speed and depressive mood explained around 26% and 8%, respectively, of the association between falls and cognitive decline.

Conclusions

Injurious falls are associated with greater cognitive decline, and this association is partly mediated by worsening of physical performance and, in a lesser extent, of depressive mood. These findings suggest that physical deficits and low mood are potential therapeutic targets for mitigating the association between falls and cognitive decline.

Bibliometric Analysis on Research Trend of Accidental Falls in Older Adults by Using Citespace-Focused on Web of Science Core Collection (2010-2020)

The present study aimed to identify the trends in research on accidental falls in older adults over the last decade. The MeSH (Medical Subject Headings) and entry terms were applied in the Web of Science Core Collection. Relevant studies in English within articles or reviews on falls in older adults were included from 2010 to 2020. Moreover, CiteSpace 5.6.R5 (64-bit) was adopted for analysis with scientific measurements and visualization. Cooper Cyrus, Stephen R Lord, Minoru Yamada, Catherine Sherrington, and others have critically impacted the study of falls in older adults. Osteoporosis, dementia, sarcopenia, hypertension, osteosarcopenia, traumatic brain injury, frailty, depression, and fear of falling would be significantly correlated with falls in older adults. Multiple types of exercise can provide effective improvements in executive cognitive performance, gait performance, quality of life, and can also lower the rates of falls and fall-related fractures. Fall detection, hospitalization, classification, symptom, gender, and cost are the current research focus and development direction in research on falls in older adults. The prevention of falls in older adults is one of the most important public health issues in today’s aging society. Although lots of effects and research advancements had been taken, fall prevention still is uncharted territory for too many older adults. Service improvements can exploit the mentioned findings to formulate policies, and design and implement exercise programs for fall prevention.

Falls and fear of falling among older adults in an assisted-living facility: A qualitative and foundational study for intervention development in a developing country

BACKGROUND

Falls and fear of falling (FOF) have serious adverse effects for older adults. Culturally-specific and environmentally-tailored interventions may help address the problems of falls and FOF. No such interventions are however available for use in the African context.

OBJECTIVE

To explore falls and FOF among older adults in an assisted-living facility, as a foundation for developing interventions to address falls and FOF.

METHODS

This qualitative study involved purposefully recruiting nine older adults and four caregivers at an assisted-living facility in Southeast Nigeria. Focus group discussions were conducted separately for older adults and the caregivers. Data were analysed using an Inductive Approach.

RESULTS

Four themes emerged: incidence of falls and fear of falling; factors associated with falls and fear of falling; health implications of falls and fear of falling; and coping strategies to deal with falls and fear of falling. Older adults were experiencing a high prevalence of falls and FOF perceived to be caused by both cultural/environmental/institutional-related factors (poorly lit environment at night; poor ambulatory surfaces; unwillingness to accept age-related changes in physical capacity; poor disposition towards walking aids; poor treatment of injuries; misconceptions; poor physical activity participation; and external perturbation) and intrinsic factors (psychological/emotional, concentration/attention, socio-demographic and morbidity-related).

CONCLUSION

The older adults were experiencing a high prevalence of falls and FOF which has a multifactorial origin of common and cultural/societal/institutional/environmental-related factors. The need for a multicomponent and culturally and environmentally-specific interventions to address falls and FOF in this sample is thus highlighted.

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.

Association between Frailty and Mortality, Falls, and Hospitalization among Patients with Hypertension: A Systematic Review and Meta-Analysis

OBJECTIVE

Chronological age alone does not adequately reflect the difference in health status of a patient with hypertension. Frailty is closely associated with biological age, and its assessment is clinically useful in addressing the heterogeneity of health status. The purpose of our study is to comprehensively examine the predictive value of frailty for negative health outcomes in hypertensive patients through a systematic review and meta-analysis.

METHODS

Multiple English and Chinese databases were searched from inception to 04.11.2020. All cross-sectional and longitudinal studies that examined the association between frailty and relevant clinical outcomes among hypertensive patients were included. The NOS was used to assess the risk of bias of studies included in the analysis. Hazard ratios (HRs), odds ratios (ORs), and 95% confidence intervals (CIs) were pooled for outcomes associated with frailty.

RESULTS

Six longitudinal studies and one cross-sectional study involving 17403 patients with hypertension were included in the meta-analysis. The risk of bias of all included studies was rated as low or moderate. The pooled HR of frailty related to mortality was 2.45 (95% CI: 2.08-2.88). The pooled HR of prefrailty and frailty-related injurious falls was 1.07 (95% CI: 0.83-1.37) and 1.89 (95% CI: 1.56-2.27), respectively. The pooled HR of prefrailty and frailty-related hospitalization was 1.54 (95% CI: 1.38-1.71) and 1.94 (95% CI: 1.17-3.24), respectively.

CONCLUSIONS

This systematic review suggests that frailty was a strong predictor of mortality, hospitalization, and injurious falls among patients with hypertension. Our findings indicate that assessment of frailty in patients with hypertension to guide their management may be necessary in clinical setting. However, our finding was based on very limited amount studies; thus, future studies are required to further validate the role of frailty in prediction of negative health outcomes in hypertensive patients as well as pay more attention to the following knowledge gaps: (1) the association between frailty and hypertension-related outcomes, (2) the significance of the association between different frailty models and relevant clinical outcomes, and (3) the predictive value of prefrailty for the negative health outcomes in people with hypertension.

Associations between sleep duration, midday napping, depression, and falls among postmenopausal women in China: a population-based nationwide study

OBJECTIVE

To explore the independent and joint associations of sleep duration, midday napping, and depression with fall accidents in Chinese postmenopausal women.

METHODS

A total of 2,378 postmenopausal women aged ≥ 45 years from the baseline survey of the China Health and Retirement Longitudinal Study were enrolled in the study. Each participant provided data on falls, sleep duration, midday napping by a self-reporting approach. We employed the Chinese version of the Center for Epidemiologic Studies Depression Scale to assess depression. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated to estimate the associations of predictor variables with falls using multivariate logistic regression.

RESULTS

Of the 2,378 postmenopausal women, 478 (20.10%) reported falls in the preceding 2 years. Compared with sleep duration of 7 to 8 h/night, sleep duration of 5 to 6 h/night (OR, 1.49; 95% CI, 1.03-2.15) and of ≤ 5 h/night (OR, 1.63; 95% CI, 1.18-2.25) were associated with a higher fall prevalence. However, no significant correlation was found between sleep duration of > 8 h/night and falls. Furthermore, participants with depression were more likely to report falls (OR, 1.78; 95% CI, 1.41-2.25) than their depression-free counterparts. The duration of midday napping was not independently associated with falls, but significant joint associations of sleeping ≤ 6 h/night and no napping (OR, 1.72; 95% CI, 1.07-2.76) or napping > 60 minutes (OR, 2.14; 95% CI, 1.18-3.89) with more falls were found. Similarly, a combined status of sleeping ≤ 6 h/night and depression was related to more falls (OR, 2.97; 95% CI, 1.86-4.74).

CONCLUSION

The present study demonstrates that short sleep duration and depression are independently associated with more falls among postmenopausal women in China. Moreover, short sleep duration combined with no or long napping, short sleep duration combined with depression are jointly correlated with more falls. Future longitudinal studies are warranted to confirm these findings.

Are There Any Red Flag Injuries in Severely Injured Patients in Older Age?

Introduction: Severely injured elderly patients pose a significant burden to trauma centers and, compared with younger patients, have worse prognoses and higher mortality rates after major trauma. The objective of this study was to identify the etiological mechanisms that are associated with severe trauma in elderly patients and to detect which injuries correlate with high mortality in elderly patients. Methods: Using a prospect cohort study model over an 11-year period, severely injured patients (ISS ≥ 16) were divided into two age groups (Group 1: 18–64; Group 2: 65–99 years). A comparison of the groups was conducted regarding injury frequency, trauma mechanism, distribution of affected body parts (AIS and ISS regions) and injury related mortality. Results: In total, 1008 patient were included (Group 1: n = 771; Group 2: n = 237). The most relevant injury in elderly patients was falling from low heights (<3 m) in contrast to traffic accident in young patients. Severely injured patients in the older age group showed a significantly higher overall mortality rate compared to the younger group (37.6% vs. 11.7%; p = 0.000). In both groups, the 30-day survival for patients without head injuries was significantly better compared to patients with head injuries (92.7% vs. 85.3%; p = 0.017), especially analyzing elderly patients (86.6% vs. 58.6%; p = 0.003). The relative risk of 30-day mortality in patients who suffered a head injury was also higher in the elderly group (OR: Group 1: 4.905; Group 2: 7.132). Conclusion: In contrast to younger patients, falls from low heights (<3 m) are significant risk factors for severe injuries in the geriatric collective. Additionally, elderly patients with an ISS ≥ 16 had a significantly higher mortality rate compared to severe injured younger patients. Head injuries, even minor head traumata, are associated with a significant increase in mortality. These findings will contribute to the development of more age-related therapy strategies in severely injured patients.

Physical activity level, fear of falling and quality of life: a comparison between community-dwelling and assisted-living older adults

Background

Physical activity (PA), fear of falling (FOF) and quality of life (QOL) are very important constructs in geriatrics. The interplay among these constructs may vary between community-dwelling and assisted-living older adults. However, studies comparing the wellbeing of community-dwelling older adults with those residing in the assisted-living facilities (ALFs) are rather rare especially from developing countries. This study was aimed at comparing PA, FOF and QOL between assisted-living and community-dwelling older adults and also determining the correlations amongst the constructs for each group.

Methods

This cross-sectional survey involved consecutively sampled 114 older adults (≥65 years, ambulant and well-oriented in time, place and person) residing in conveniently selected ALFs (11.3% males) and adjoining communities (54.1% males). PA, FOF and QOL were evaluated using the Physical Activity Scale for the Elderly, the Modified Fall Efficacy Scale and the Short-form Health Survey (SF-36) questionnaire respectively. Data was analysed using descriptive statistics, analysis of covariance and Spearman rank-order correlation test at 0.05 level of significance.

Results

Participants from the ALFs had significantly lower domain and overall PA (F=5.6–103.34; p< 0.05) and QOL (F=11.12–118.05; p< 0,05) scores than community-dwelling groups. FOF was significantly more prevalent in assisted-living group (p< 0.05). There were significant positive correlations (p< 0.05) between each pair of PA, FOF and QOL for both assisted-living and community-dwelling groups.

Conclusions

Older adults in the ALFs had lower PA and QOL scores with higher prevalence of FOF than their community-dwelling counterparts. Significant relationships existed between PA, FOF and QOL for participants in either group. Present results may be suggesting that ageing in place ensures better health outcomes than institutionalised ageing. Whenever possible, older adults should therefore be encouraged to age in place rather than moving into ALFs.

Association of Frailty Status with Risk of Fall among Middle-Aged and Older Adults in China: A Nationally Representative Cohort Study

OBJECTIVES

To investigate the association between frailty status and risk of fall among middle-aged and older Chinese people.

DESIGN

A nationally representative prospective cohort study.

SETTING AND PARTICIPANTS

The study included 13,877 community-dwelling participants aged 45 years and above from the China Health and Retirement Longitudinal Study.

METHODS

Frailty status was identified by the frailty index of health deficit accumulation. 34 variables at baseline were selected to calculate the frailty index. We excluded participants with incomplete information in construction of the frailty index at baseline. Falls were measured based on the respondents' self-report. We used a logistic regression model to estimate the associations between the frailty status and risk of fall, and subgroup analyses and sensitivity analyses were further conducted.

RESULTS

Of 13,877 participants, 2310 (16.6%) had falls during the observation period. 9027 (65.0%) participants were classified as robust, 4019 (29.0%) participants were classified as pre-frail, and 831 (6.0%) participants were classified as frail. Our results indicated per 0.01 increment in the frailty index was significantly associated with an increased risk of fall among middle-aged and older participants (OR: 1.52, 95%CI: 1.45-1.60). Such association was stronger when frailty was presented as a categorical variable, with an OR of 1.75 (95%CI: 1.59-1.93) for pre-frail and 3.04 (95%CI: 2.60-3.56) for frail. The area under the curve of the logistic model was 0.612 (95%CI: 0.600-0.625). Each 0.01 increment of the frailty index was association with a higher risk of fall among middle-aged (45-59years) participants (OR: 1.44, 95%CI: 1.29-1.60) than among older (≥60 years) participants (OR: 1.28, 95%CI: 1.16-1.41) at baseline (p=0.015 for interaction).

CONCLUSION

Frailty was significantly associated with an increased risk of fall among community-dwelling middle-aged and older people in China. It is necessary to screen and recognize frailty status to prevent falls among middle-aged and older adults.

The Impact of Frailty on COVID-19 Outcomes: A Systematic Review and Meta-analysis of 16 Cohort Studies

BACKGROUND

Frail patients are increasingly vulnerable to stress, which is mainly manifested by a reduced physiologic reserve in metabolic and immune systems and neuromuscular system. Several studies found a significant association of frailty with COVID-19 severity to support the evidence for the application of frailty assessment. However, there were contradictory results in other studies. Thus we conducted a systematic review and meta-analysis to synthesize the current studies to investigate impact of frailty on COVID-19 outcomes and provide evidence-based decisions in clinical practice.

OBJECTIVE

We aimed to synthesize the current studies to investigate impact of frailty on COVID-19 outcomes and provide evidence-based decisions in clinical practice.

DESIGN

A systematic review and Meta-analysis of 16 cohort studies.

PARTICIPANTS

Patients with COVID-19.

METHODS

A systematic retrieving for potential literature was conducted in several public electronic databases, including Medline(OvidSP), EMBASE, Pubmed and Chinese databases(China National Knowledge Infrastructure,Wanfang and Weipu) on August 1, 2020.The literature research was updated on October 26, 2020. Newcastle Ottawa Scale for cohort studies was used for quality assessment. RevMan (Version 5.3) and Stata 14.0 were used to synthesize the pooled effects.

RESULTS

According to the predefined inclusion and exclusion criteria, sixteen studies of 4324 patients were included in the final analysis. Frailty was significantly associated with increased risk of all-cause mortality among patients with COVID-19, with pooled adjusted odds ratios of 1.81 (95% confidence intervals:1.48,2.21, I2=87.0%, P<0.001). The result was consistent in stratified analysis to according to age, patient source, definitions of frailty, study quality, and adjustment method. Frailty was significant associated with an increased risk of COVID-19 severity, admission to intensive care unit, application of invasive mechanical ventilation, long-length stay.

CONCLUSIONS

In this meta-analysis, we found frailty was significantly associated with an increased risk of clinical adverse events (all- cause mortality, COVID-19 severity, admission to the intensive care unit, application of invasive mechanical ventilation, long-length stay). Given the epidemic of COVID-19 and shortage of medical resources, paying more attention to screening frailty would contribute to disease management and resource allocation among patients with COVID-19.

Can the Timed Up & Go Test and Montreal Cognitive Assessment predict outcomes in patients waitlisted for renal transplant?

PURPOSE

Frail patients who undergo renal transplantation (RT) have more complications; however, little is known if these patients can sustain the wait to RT. We used the Timed Up and Go Test (TUGT) and Montreal Cognitive Assessment (MoCA) to determine outcomes of RT candidates.

METHODS

In this retrospective study, 526 RT candidates underwent TUGT and MoCA (2015-2019) and were divided into "favorable" (transplanted or remained on the list) or "unfavorable" (not listed, removed from list, or died) outcome. Demographics, education, language, comorbidities, dialysis type, use of a walking device, TUGT, and MoCA were compared by outcome.

RESULTS

Overall, 230 patients (43.7%) passed TUG, 268 (51%) passed MoCA, 133 (25.3%) passed both, and 161 (30.6%) failed both tests. Multivariate analysis demonstrated age ≥ 65 (OR 1.58, CI 1.03-2.43), cardiac disease (OR 3.09, CI 2.02-4.72), ≥36 months on dialysis (OR 1.80, CI 1.24-2.69), EPTS < 20% at time of MoCA (OR 0.26, CI 0.07-0.98), and failing TUGT (OR 2.14, CI 1.43-3.19) were associated with unfavorable outcome. Failing MoCA was not associated with outcome.

CONCLUSIONS

MoCA test results were not associated with RT waitlist outcomes; however, passing the TUGT was associated with receiving RT or remaining on the list. Additional studies are needed to validate this and determine outcome after RT.

The association between apathy and frailty in older adults: a new investigation using data from the Mapt study

INTRODUCTION

Apathy is a behavioral syndrome that has been suggested to share similar neuro-physiological pathways with frailty.

OBJECTIVE

To investigate the cross-sectional association between apathy and frailty using original data from dementia-free, community-dwelling older adults.

METHOD

A cross-sectional analysis was performed to test the association between frailty (according to Fried's frailty phenotype) and apathy (defined by three items from Geriatric Depression Scale) using data from MAPT, a 3-year, randomized, multicenter, placebo-controlled trial among community-dwelling, dementia-free participants (1.679 individuals with mean age of 75 years).

RESULTS

The ordinal logistic regression showed that apathetic individuals had a two-fold more probability to be rated as frail (OR 2.20, 95% CI 1.7-2.9), when adjusting for confounders. Apathetic individuals display a two-fold more likelihood to be rated as pre-frail (RRR 2.1; 95% CI 1.5-2.8) and a three-fold higher probability to be rated as frail (RRR 3.5, 95% CI 1.8-6.9) compared to robust participants.

CONCLUSION

Although data on the associations between apathy and frailty are scarce, these conditions potentially shares physiological mechanisms and were found to be closely associated. Temporal association between frailty and apathy deserve to be further investigated.

Cognitive frailty and falls in Chinese elderly people: a population-based longitudinal study

BACKGROUND AND PURPOSE

Falling is considered an important public health problem among older people. A recent cross-sectional study suggested that cognitive frailty (CF) is associated with falls. We aimed to explore whether CF is a risk factor for falls in a population-based longitudinal study.

METHODS

Using data from the Rugao Longevity and Aging Study, physical frailty was assessed according to the modified Fried's phenotype, and the 20% of participants with the lowest scores on the Revised Hasegawa Dementia Scale were defined as having cognitive impairment (CoI). Cognitive frailty (CF) was defined as the coexistence of physical frailty and CoI, but excluded severe CoI (revised Hasegawa Dementia Scale score ≤ 10). The outcome of number of falls in the previous 12 months was measured using a questionnaire.

RESULTS

At baseline, the prevalence of CF was 2.6% and the prevalence of two or more falls was 6.7%. Cross-sectional analysis found that two or more falls was associated with physical frailty without CoI (odds ratio [OR] 6.79, 95% confidence interval [CI] 3.17-14.56), pre-frailty with CoI (OR 4.54, 95% CI 2.44-8.44) and CF (OR 3.51, 95% CI 1.18-10.44). Slow gait with CoI was associated with two or more falls (OR 2.21, 95% CI 1.08-4.53). At 3-year follow-up, the prevalence of two or more falls was 10.6%. Logistic regression analysis showed that, compared with the robust and non-CoI elderly groups, the CF elderly group had a higher risk of two or more falls (OR 3.41, 95% CI 1.11-10.50).

CONCLUSIONS

Cognitive frailty was associated with two or more falls at baseline and might be a risk factor for two or more falls after 3 years. Early screening of CF might be beneficial in the prevention of falls.

Self-reported fatigue: A significant risk factor for falling in older women and men

OBJECTIVE

To determine whether fatigue may be a risk factor for falling in older men and women, independent of other components of the frailty phenotype, fear of falling, and physical performance.

DESIGN

Among 986 women and 485 men visiting a health resort (mean age 72.3 and 72.7, respectively), subjects with at least one fall in the previous year were compared with non-fallers using a multivariate logistic regression analysis. Age, fatigue and fear of falling over the previous month were assessed by visual analogue scale (VAS), and the past 7 days of activity were assessed using the International Physical Activity Questionnaire. The following parameters were also assessed: weight loss in the past year, maximum grip strength measured with a hand dynamometer, time to perform the 5-chair stand and the up and go tests, time to walk 4 m, time held on one leg, feet together, as well as in the semi-tandem and tandem positions.

RESULTS

A feeling of fatigue (VAS score ≥ 5/10 in women or ≥4/10 in men), a fear of falling (VAS score ≥ 4/10 in women or ≥2 in men), and poor balance (time held in semi-tandem position < 10 s in women and time held on one leg < 6.5 s in men) were the 3 independent parameters distinguishing fallers from non-fallers.

CONCLUSION

The present study suggests the interest of adding a VAS score of fatigue to that of fear of falling and balance measurements for screening men and women aged 65 or older who are at risk of falls.

Associations between Pet Ownership and Frailty: A Systematic Review

Frailty is defined as a state of increased vulnerability due to age-related decline in reserve and function across multiple physiological systems. Increasing physical activity level is considered to be a measure to counteract frailty. Some studies have indicated that pet owners are more engaged in physical activity than non-owners. We conducted a systematic review regarding associations between pet ownerships and frailty among community-dwelling older adults and critically assessed the findings. PubMed was searched in April 2020 according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines for cross-sectional or prospective studies examining associations between pet ownership and frailty in community-dwelling older adults with a mean age of 60 or above. A supplementary search was done using Google Scholar. Identified articles were reviewed by two investigators independently and assessed for methodological quality. The search identified 48 studies, among which three studies (two cross-sectional and one prospective) were included in this review. These studies suggested that pet ownership may be associated with a lower risk of frailty. This systematic review found only a limited amount of relevant research. More research is needed to establish the link between pet ownership and frailty as well as healthy aging and well-being.

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.

Falls, frailty, and metabolic syndrome in urban dwellers aged 55 years and over in the Malaysian elders longitudinal research (MELoR) study - a cross-sectional Study

OBJECTIVES

While metabolic syndrome, falls, and frailty are common health issues among older adults which are likely to be related, the potential interplay between these three conditions has not previously been investigated. We investigated the relationship between metabolic syndrome with falls, and the role of frailty markers in this potential relationship, among community-dwelling older adults.

METHODS

Data from the first wave Malaysian Elders Longitudinal Research (MELoR) study comprising urban dwellers aged 55 years and above were utilized. Twelve-month fall histories were established during home-based, computer-assisted interviews which physical performance, anthropometric and laboratory measures were obtained during a hospital-based health check. Gait speed, exhaustion, weakness, and weight loss were employed as frailty markers.

RESULTS

Data were available for 1415 participants, mean age of 68.56 ± 7.26 years, 57.2% women. Falls and metabolic syndrome were present in 22.8% and 44.2%, respectively. After adjusting for age, sex, and multiple comorbidities, metabolic syndrome was significantly associated with falls in the sample population [odds ratio (OR): 1.33, 95% confidence interval (CI): 1.03; 1.72]. This relationship was attenuated by the presence of slow gait speed, but not exhaustion, weakness, or weight loss.

CONCLUSION

Metabolic syndrome was independently associated with falls among older adults, and this relationship was accounted for by the presence of slow gait speed. Future studies should determine the value of screening for frailty and falls with gait speed in older adults with metabolic syndrome as a potential fall prevention measure.

Frailty and prediction of recurrent falls over 10 years in a community cohort of 75-year-old women

Background

Frailty captures the age-related declines in health leading to increased vulnerability, including falls which are commonplace in older women. The relationship between frailty and falls is complex, with one leading to the other in a vicious cycle.

Aims

This study addresses the gap in understanding how patterns of frailty and falls propensity interact, particularly in those who have not yet entered the falls-frailty cycle.

Methods

The Osteoporosis Risk Assessment cohort consists of 1044 community-dwelling women aged 75, with 10 years of follow-up. Investigations were performed and a frailty index constructed at baseline, 5 and 10 years. Falls were self-reported for each previous 12 months. Analysis was two-directional, firstly based on frailty status and second, based on falls status. Recurrent falls was the primary outcome.

Results

Baseline frailty was a significant predictor of recurrent falls after 5 and 10 years [(OR 2.55 (1.62–3.99); 3.04 (1.63–5.67)]. Among women who had no history of falls at age 75, frailty was a stronger predictor of falls at 5 years [OR 3.06 (1.59–5.89)] than among women who had previously fallen.

Discussion

Frailty is significantly associated with recurrent falls and most pronounced in those who are frail but have not yet fallen.

Conclusions

This suggests that frailty should be an integral part of falls-risk assessment to improve identification of those at risk of becoming fallers.

Helicobacter pylori Related Diseases and Osteoporotic Fractures (Narrative Review)

Osteoporosis (OP) and osteoporotic fractures (OFs) are common multifactorial and heterogenic disorders of increasing incidence. Helicobacter pylori (H.p.) colonizes the stomach approximately in half of the world's population, causes gastroduodenal diseases and is prevalent in numerous extra-digestive diseases known to be associated with OP/OF. The studies regarding relationship between H.p. infection (HPI) and OP/OFs are inconsistent. The current review summarizes the relevant literature on the potential role of HPI in OP, falls and OFs and highlights the reasons for controversies in the publications. In the first section, after a brief overview of HPI biological features, we analyze the studies evaluating the association of HPI and bone status. The second part includes data on the prevalence of OP/OFs in HPI-induced gastroduodenal diseases (peptic ulcer, chronic/atrophic gastritis and cancer) and the effects of acid-suppressive drugs. In the next section, we discuss the possible contribution of HPI-associated extra-digestive diseases and medications to OP/OF, focusing on conditions affecting both bone homeostasis and predisposing to falls. In the last section, we describe clinical implications of accumulated data on HPI as a co-factor of OP/OF and present a feasible five-step algorithm for OP/OF risk assessment and management in regard to HPI, emphasizing the importance of an integrative (but differentiated) holistic approach. Increased awareness about the consequences of HPI linked to OP/OF can aid early detection and management. Further research on the HPI-OP/OF relationship is needed to close current knowledge gaps and improve clinical management of both OP/OF and HPI-related disorders.

Frailty as a predictor of future falls and disability: a four-year follow-up study of Chinese older adults

BACKGROUND

Frailty, which is defined as aging-related multisystem impairments, can lead to adverse health outcomes. However, evidence for such a connection in Chinese older adults remains lacking. This study examined the association between frailty and future falls and disability among community-dwelling Chinese older adults.

METHODS

Data were obtained from the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study. Participants were aged 60 years and above at baseline in 2011 and completed the follow-up survey in 2015. Outcome measures were future falls, incident disability in activities of daily living (ADLs) and instrumental activities of daily living (IADLs), and worsening performance of ADLs and IADLs. A multivariate logistic regression was conducted to examine the association between frailty phenotype and falls, incident disability, and worsening disability during a four-year period.

RESULTS

We found that frail participants were at increased risk at follow-up for: falls (OR 1.54, 95% CI, 1.14-2.08); developing new ADL difficulties (OR 4.10, 95% CI, 2.79-6.03) and IADL difficulties (OR 3.06, 95% CI, 2.03-4.61); and worsening ADLs performance (OR 2.27, 95% CI, 1.27-4.06), after adjusting for potential confounders. Prefrailty was also significantly associated with future falls, incident disability in ADLs and IADLs, but with a lower magnitude of effect.

CONCLUSIONS

Frailty phenotype is an independent predictor of future falls, incident disability, and worsening performance in ADLs among Chinese older adults. The association suggests the need to pay special attention in caring for frail and prefrail elders and improving individuals' frailty status.

Association between frailty and risk of fall among diabetic patients

BACKGROUND

Several epidemiological studies have demonstrated the risk factors for fall, while few studies investigated the association between frailty and risk of fall in diabetic patients aged ≥45 years.

METHODS

In this multicity observational study, participants with type 2 diabetes aged ≥45 years were enrolled. Frailty status was measured by a frailty index (FI) of deficit accumulation. We used multivariable regression models to examine the relationship between frailty and fall in diabetic patients, and further investigated the associations between frailty and fall in varied subgroups.

RESULTS

A total of 2049 participants with type 2 diabetes were identified in our study. Our results showed a per-s.d. and a per-0.01 increment of FI were associated with an increased risk of fall, with a fully adjusted OR of 1.89 (95% CI: 1.50, 2.38), 1.06 (95% CI: 1.04, 1.09), respectively. The effects were magnified when frailty was considered as dichotomous, with an OR of 3.08 (95% CI: 2.18, 4.34). In further subgroup analyses, we found that the females, the older, rural residents, individuals with no sitting toilet, people with poor balance performance and those in poor health status were susceptible to fall. Especially, for the risk of fall in the older, a per-s.d. increase of FI corresponded to an OR of 2.46 (95% CI: 1.68, 3.62). When frailty was regarded as a binary variable, the effect increased to 4.62 (95% CI: 2.54, 8.38) in the older subgroup.

CONCLUSION

Frailty was associated with a higher risk of fall in people with type 2 diabetes, and the effects were higher in vulnerable groups. This evidence suggested that more attention should be paid to vulnerable groups for fall prevention.

Care Professionals Manage the Future, Frail Older Persons the Past. Explaining Why Frailty Management in Primary Care Doesn't Always Work

Frailty management focuses on optimizing the physical and psychological functioning of older people with frail health through early risk identification and intervention in primary care. Such care programs demand a joint effort by primary care professionals and older persons, one in which professionals are expected to promote or facilitate self-management practices and older persons are expected to adhere to the professional advice. It is known that patients and professionals hold different perspectives on frailty, but we know little about how this may affect their cooperation in frailty management. In this article, we therefore study how different perspectives of older persons and their primary care professionals play a role frailty management in practice. Nine cases of frailty management were reconstructed through semi-structured interviews with older persons, their family doctor and practice nurse. Drawing from literature on managing complex problems, we analyzed how "factual" and "normative" orientations played a role in their perspectives. We observe that the perspectives of care professionals and older persons on frailty management were substantially different. Both actors "manage" frailty, but they focus on different aspects of frailty and interestingly, care professionals' rationale is future-oriented whereas older person's rationale past-oriented. Primary care professionals employed practices to manage the medical and social factors of frailty in order to prevent future loss. Older persons employed practices to deal with the psychological, emotional and social aspects of the different types of loss they already experienced, in order to reconcile with loss from the past in the present. These findings raise fundamental questions regarding the different perceptions of and priorities around not only care for frail older people in general, but also implied professional-patient relations and the value of a risk-management approach to care for older people with frail health. The distinction between these perspectives could help care professionals to better respond to older patients' preferences and it could empower older persons to voice preferences and priorities that might not fit within the proposed care program.

Preserving Mobility in Older Adults with Physical Frailty and Sarcopenia: Opportunities, Challenges, and Recommendations for Physical Activity Interventions

One of the most widely conserved hallmarks of aging is a decline in functional capabilities. Mobility loss is particularly burdensome due to its association with negative health outcomes, loss of independence and disability, and the heavy impact on quality of life. Recently, a new condition, physical frailty and sarcopenia, has been proposed to define a critical stage in the disabling cascade. Physical frailty and sarcopenia are characterized by weakness, slowness, and reduced muscle mass, yet with preserved ability to move independently. One of the strategies that have shown some benefits in combatting mobility loss and its consequences for older adults is physical activity. Here, we describe the opportunities and challenges for the development of physical activity interventions in people with physical frailty and sarcopenia. The aim of this article is to review age-related physio(patho)logical changes that impact mobility in old age and to provide recommendations and procedures in accordance with the available literature.

Analysis of the health profiles and prevalence of falls for patients over 65 years of age in a thermal environment

BACKGROUND

A falls prevention programme has been initiated in balneotherapy at Balaruc-les-Bains.

AIMS

To determine the health profiles of subjects who are at risk of falls, over 65 years of age and attending balneotherapy.

METHODS

Questionnaires were used to evaluate people on their fear of falling. Fatigue was assessed by visual analog scale as well as by functional status over the past 12 months. EQ-5D-3L, the IPAQ questionnaire and Fried's frailty scale were all used. Patients' functional capabilities were tested using the Unipedal stance test, the TUG test, the SPPB, the Tandem walking test and the isometric manual grip strength test.

RESULTS

Out of the 1471 patients (72.45 years ± 5.10), the women (67%) were tested. In the last 12 months, 485 of these 1471 patients fell (33%) and 37% of them suffered a severe injury. 45-50% of these subjects are now in good health. Women had a significantly higher impaired perception of their health than men (0.02 < p < 0.0001). According to Fried's criteria, 10.2% of the population is considered frail, with a significantly greater number of women (p < 0.0001). Static equilibrium was subnormal (less than 12 s during the TUG). The number of steps in tandem position discriminates individuals and gender as does the speed of moving from A to B and muscular strength.

CONCLUSIONS

More than one-third of the subjects (more women than men) aged 65 or older visiting the Balaruc-les-Bains health resort are pre-frail or frail. They all have a recent history of falls, suffer from impaired muscle strength, and have balance and gait disorders.

COVID-19 and associations with frailty and multimorbidity: a prospective analysis of UK Biobank participants

BACKGROUND

Frailty and multimorbidity have been suggested as risk factors for severe COVID-19 disease.

AIMS

We investigated, in the UK Biobank, whether frailty and multimorbidity were associated with risk of hospitalisation with COVID-19.

METHODS

502,640 participants aged 40-69 years at baseline (54-79 years at COVID-19 testing) were recruited across UK during 2006-10. A modified assessment of frailty using Fried's classification was generated from baseline data. COVID-19 test results (England) were available for 16/03/2020-01/06/2020, mostly taken in hospital settings. Logistic regression was used to discern associations between frailty, multimorbidity and COVID-19 diagnoses, after adjusting for sex, age, BMI, ethnicity, education, smoking and number of comorbidity groupings, comparing COVID-19 positive, COVID-19 negative and non-tested groups.

RESULTS

4510 participants were tested for COVID-19 (positive = 1326, negative = 3184). 497,996 participants were not tested. Compared to the non-tested group, after adjustment, COVID-19 positive participants were more likely to be frail (OR = 1.4 [95%CI = 1.1, 1.8]), report slow walking speed (OR = 1.3 [1.1, 1.6]), report two or more falls in the past year (OR = 1.3 [1.0, 1.5]) and be multimorbid (≥ 4 comorbidity groupings vs 0-1: OR = 1.9 [1.5, 2.3]). However, similar strength of associations were apparent when comparing COVID-19 negative and non-tested groups. However, frailty and multimorbidity were not associated with COVID-19 diagnoses, when comparing COVID-19 positive and COVID-19 negative participants.

DISCUSSION AND CONCLUSIONS

Frailty and multimorbidity do not appear to aid risk stratification, in terms of positive versus negative results of COVID-19 testing. Investigation of the prognostic value of these markers for adverse clinical sequelae following COVID-19 disease is urgently needed.

National prevalence of frailty in the older Japanese population: Findings from a nationally representative survey

BACKGROUND

Japan has the largest aging population in the world, thus, a focus on frailty is important in clinical geriatric practice. Using a nationally representative sample, this study provided national estimates of the prevalence of frailty among community-dwelling older Japanese people. We also examined variations in the prevalence by sociodemographic characteristics, health conditions, and geographical regions.

METHODS

Data came from the National Survey of the Japanese Elderly in 2012. The data were collected using a home visit and face-to-face interviews with trained interviewers. The sample consisted of 2206 adults aged ≥65 years. We used the widely accepted definition of physical frailty phenotype and calculated weighted estimates of the prevalence of frailty.

RESULTS

Overall estimated prevalence was 8.7 % (7.5 %-9.9 %) for frail, 40.8 % (38.7 %-42.9 %) for prefrail, and 50.5 % (48.4 %-52.6 %) for robust. Frailty was more prevalent in older groups, women, and those with lower socioeconomic status, which was measured by education and household income. Frail people tended to have worse health. We also observed a regional variation: frailty prevalence tended to be higher in eastern than western Japan.

CONCLUSIONS

This study provides important evidence on the prevalence of frailty in older Japanese people and found substantial disparities by sociodemographic characteristics, health conditions, and geographical regions.

Falls and visual impairment among elderly residents in 'homes for the aged' in India

We evaluated the prevalence of falls and their association with visual impairment (VI) in elderly residents in 'homes for the aged' in Hyderabad, India. Participants aged ≥ 60 years were recruited from 41 homes, and a comprehensive eye examination was conducted. Interviews were conducted to collect personal and demographic information, systemic health status, fear of falling, depression, and history of falls in the last year. VI categories included low vision (presenting visual acuity worse than 6/18 to 3/60) and blindness (presenting visual acuity worse than 3/60). The data of 1,074 participants were analysed. The mean age was 74.4 years (standard deviation:8.7 years); 63.9% were women, 19.4% had no formal education, 28.1% were diabetic and 56.9% were hypertensive. The annual prevalence of falls was 29.1% (95% CI: 26.4-32.0). Multivariable analysis showed those with VI had significantly higher odds of falls (Odds Ratio:1.47; p = 0.043). The prevalence of falls was higher among those with VI due to uncorrected refractive errors. We found a very high prevalence of falls in elderly individuals living in 'homes for the aged' in Hyderabad, India. Addressing VI can result in fewer falls and contribute to healthy aging in India.

Association between lifestyle behaviors and frailty in Atlantic Canadian males and females

PURPOSE

The aim of this study was to identify lifestyle factors in males and females that are associated with a greater degree of frailty in a Canadian cohort.

METHODS

Cross-sectional data analysis from participants aged 30-74 yrs of the Atlantic PATH cohort. Inclusion criteria included completion of mental health questionnaires and ≥1 vital measure (n = 9133, 70% female, mean age 55 yrs). A frailty index was created based on 38 items with higher values indicating increasing frailty. The association between lifestyle factors and frailty was assessed by logistic regression.

RESULTS

805 participants had a high level of frailty (frailty index ≥0.30). There was a significant interaction among sex, age, and lifestyle factors such as smoking status (P < 0.001), alcohol consumption (P < 0.001), physical activity level (P = 0.005), time spent sitting (P < 0.001) and sleeping (P < 0.001) on frailty. Smoking was harmful whereas sleep was protective for both males and females (<60 yrs). Females (<60yrs) that sat for ≥4 h/day were more likely to be highly frail whereas females (all ages) that consumed alcohol at least occasionally were less likely to be highly frail. Males, but not females, that engaged in a high level of physical activity were less likely to have a high level of frailty.

CONCLUSIONS

Higher frailty is more prevalent among participants with unhealthy lifestyle behaviors related to smoking, alcohol consumption, sedentary and physical activity level, diet, and sleep. Differences in lifestyle behaviors of males and females of specific ages should be considered for managing frailty levels.

Lifestyle Activity Patterns Related to Physical Frailty and Cognitive Impairment in Urban Community-Dwelling Older Adults in Japan

OBJECTIVES

Investigating the lifestyle activity patterns of urban community-dwelling Japanese older adults, focusing on physical frailty and cognitive impairment.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

Participants comprised 8003 older adults (4489 women; mean age: 72.5 years, SD = ±6.1, range 60-95 years) from the National Center for Geriatrics and Gerontology Study of Geriatric Syndromes.

METHODS

Participants reported on their lifestyle activity status, including using public transport, grocery shopping, light exercise, gardening, money management, meeting friends, participating in events, and travel. Several potential confounding variables, such as demographic characteristics, were considered. We assessed their lifestyle activity patterns using a latent class analysis and defined physical frailty by either slow walking speed or poor grip strength. Cognitive impairment was defined by participants exhibiting more than 1 of the following symptoms: poor word list memory, poor attention, reduced executive function, and low processing speed test scores. We also examined the relationship between their lifestyle activity patterns and physical frailty and cognitive impairment.

RESULTS

The overall prevalence of robustness, physical frailty, cognitive impairment, and frailty and cognitive impairment was 54.6%, 21.4%, 13.3%, and 10.7%, respectively. We defined 4 classes using latent class analysis: greater engagement in multidomain activities, lower engagement in going-out activities, lower engagement in cognitive and physical activities, and lower engagement in multidomain activities. Moreover, physical frailty and cognitive impairment were independently associated with lower engagement in going-out activity, lower engagement in cognitive and physical activities, and lower engagement in multidomain activities, after adjusting for covariates.

CONCLUSIONS AND IMPLICATIONS

Considering an older adult's lifestyle activity patterns in their day-to-day practice, clinicians can deliver more older adult-centered care, which in turn might lead to better outcomes in the primary prevention of disease.

The Association Between Comorbidity, Frailty, and Outdoor Mobility Loss Among Community-Dwelling Individuals 60 Years of Age and Above in Moscow

To determine the prognostic value of frailty and comorbidity for outdoor mobility loss and mortality in the elderly. The retrospective study was conducted among outpatients aged ≥60 years. Patients with ≥3 chronic illnesses were treated by doctors who had undergone a 72-hour geriatric training. The outdoor low-mobility group comprised patients who failed to visit a doctor because of decreased outdoor mobility during the 3-year follow-up period. The outdoor high-mobility group comprised participants with no outdoor mobility loss. 5678 patients with a mean age of 71.0 ± 0.1 years were included in the study. The risk of outdoor mobility loss rose by 4% per year with men developing it 30% more than women. The effect of frailty was of particular importance because it increased the risk of developing outdoor mobility loss by 70%. Comorbidity was not associated with a higher risk of outdoor mobility loss, but the investigators did not take into account all possible illnesses, or the severity of disease. The loss of outdoor mobility was associated with increase in mortality. Early detection of frailty can help predict outdoor mobility loss and could reduce mortality among older people.

Prevalence and Correlates of Frailty in Community-Dwelling Older Adults with Chronic Pain: A Cross-Sectional Study

BACKGROUND

Frailty is a frequent health condition in older adults of decreased functional reserve that leads to vulnerability to internal and external stressors. It has been associated with chronic pain, which is a common, costly and incapacitating condition in older adults.

AIMS

To describe frailty status in a sample of community-dwelling older adults with chronic pain attending a primary health care centre.

DESIGN

Cross-sectional investigation.

PARTICIPANTS

Adults aged 65 years or older with chronic pain.

METHODS

The Survey of Health, Ageing and Retirement in Europe Frailty Instrument (SHARE-FI) was used to assess frailty status and a visual analogue scale to assess pain intensity. Descriptive and analytical statistics were performed.

RESULTS

Among 154 participants recruited, 20.1% were frail, 38.3% pre-frail and 41.6% robust. Women were more likely to be classified as frail or pre-frail (OR: 4.62, 95% CI: 2.23-9.59), as well as participants aged 75 years or older (OR: 3.41, 95% CI: 1.74-6.68) and participants reporting moderate and severe pain (OR: 4.20, 95% CI: 2.10-8.40). These results remained significant after adjustment.

CONCLUSIONS

There is an association between frailty status and other variables such as older age, female gender and higher pain intensity.

Physical Frailty and Fall Risk in Community-Dwelling Older Adults: A Cross-Sectional Study

Introduction

Frailty is a condition in older adults with decreased physical and cognitive performance that can affect health outcomes associated with fracture, disability, and falls. The aim of this study was to compare fall risk with different physical frailty statuses and investigate factors associated with fall risk in community-dwelling older adults.

Methods

The population studied included 367 older adults (mean age = 73.2 years ± 7.0; 237 females (64.6%) and 130 males (35.4%)) who live in Chiang Mai, Thailand. This study was of cross-sectional design. Fried's phenotype was used to screen the physical frailty status. The physiological profile assessment (PPA) was used to screen for fall risk. One-way ANOVA analysis was used to compare the fall risk between the different levels of frailty status. Linear regression analysis was used to assess the association between frailty status and fall risk.

Results

The prevalence of the frailty group was 8.7% and that of the prefrailty group was 76.8%. The three statuses of frailty identified were found to have different levels of risk of falling. The frailty group had a higher fall risk than the nonfrailty group and the prefrailty group. In addition, the nonfrailty group had a lower fall risk than the prefrailty group.

Conclusion

The frailty group had the highest fall risk in this cohort of older adults living in a community-dwelling facility. Therefore, it is important to assess the frailty status among older adults as it can be a predictor for fall risk. This assessment will therefore lead to a reduction in the rate of disability and death in the community.

Risk Prediction for Adverse Outcomes for Frail Older Persons with Complex Healthcare and Social Care Needs Admitted to a Community Virtual Ward Model

Purpose

Population ageing is challenging healthcare systems with limited resources, necessitating the development of new care models to address the needs of older, frail community-dwellers. Community Virtual Wards (CVW) reduce adverse events in these patients. We examined the effect of an established CVW on pre-defined health trajectories (between “stable”, “deteriorating”, and “unstable” states) and characteristics that increased the likelihood of adverse healthcare outcomes (hospitalization, institutionalization and death).

Patients and Methods

We collected prospective data on frail patients admitted to a CVW in a single centre in Ireland. Relationships between risk scores, health states and adverse outcomes at 30, 60 and 90 days after admission were examined using multinomial regression analysis.

Results

In total, 88 community-dwellers, mean (±SD) age of 82.8 ±6.4 years, were included. Most were severely frail on the Rockwood Clinical Frailty Scale (mean 6.8/9 ±1.33). Reaching stability (“stable” state) within 30 days was a predictor for stability at 60 and 90 days and remaining at home. Stability was also associated with fewer care episodes (<2) (p=<0.001), a requirement for fewer healthcare professionals (HCP) (<7) (p<0.001) and lower risk of delirium (p<0.001). By contrast, being “unstable” at 60 days increased the numbers of HCP referrals (>7) and was predictive of more acute episodes (>2) and institutionalization or death (p<0.001). Predictors of adverse outcomes of either institutionalization or death included frailty status, function, mobility, nutrition, pressure ulcer risk and cognition.

Conclusion

A CVW model can provide a framework for monitoring and case management to support older people to remain at home or identify those at risk of institutional care. The use of defined health states helped to stratify those at lower or higher risk in an already high-risk frail population. Level of frailty, function, mobility, nutrition, pressure ulcer risks and cognition were predictive of remaining at home and reaching a level of stability or instability/deterioration and institutional care.

Skeletal Muscle Aging Atrophy: Assessment and Exercise-Based Treatment

In the ordinary course of aging, individuals change their body composition, mainly reducing their skeletal muscle mass and increasing their fat mass. In association, muscle strength and functionality also decrease. The geriatric assessment allows knowing the baseline situation of the patients, determines the impact of diseases, and defines specific treatments. There are various tools to evaluate the health condition of older people. These tools include the assessment scales of necessary Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL), physical and functional assessment scales, and instruments that assess the cognitive state of the person. There are several strategies that have been proposed to combat skeletal muscle atrophy due to aging, such as physical exercise, nutritional supplements, or drugs. Some researchers have highlighted the efficacy of the combination of the mentioned strategies. In this chapter, we will focus only on physical exercise as a strategy to reduce skeletal muscle loss during aging.

Number of Pregnancies and Trajectory of Frailty Index: English Longitudinal Study of Ageing

OBJECTIVES

Women are frailer than men across different populations and age groups. However, the mechanisms are still not fully understood. One possible cause is pregnancy and motherhood. The objective of this study was to examine trajectories of Frailty Index over time according to the number of pregnancies.

DESIGN

A prospective study with repeated measures over 14 years.

SETTING AND PARTICIPANTS

A total of 2060 community-dwelling older women aged ≥60 years in England.

METHODS

The number of pregnancies was calculated as a sum of the number of live births and the number of miscarriages, still-births, or abortions. The Frailty Index (FI) was constructed using 60 deficits and repeatedly calculated every 2 years over 14 years. Trajectories of FI according to the number of pregnancies were estimated by a mixed effects model.

RESULTS

Mean FI was 0.15 at baseline. A mixed effects model adjusted for age, smoking, alcohol use, education, and wealth showed that FI increased over time. A higher number of pregnancies were significantly associated with a higher FI (estimate = 0.0047, 95% confidence interval = 0.0020, 0.0074).

CONCLUSIONS AND IMPLICATIONS

The current study showed that a higher number of pregnancies were significantly associated with a higher degree of frailty at baseline and over time. Pregnancy and child rearing may explain some of the observed excess risk of frailty in women. Pregnancy-related factors, such as pregnancy loss, types of delivery, length of pregnancy, childbearing, and child rearing, should be examined in relation to frailty in future studies.

The diagnostic and predictive accuracy of the PRISMA-7 screening tool for frailty in older adults: A systematic review protocol

Background: Older adults are at risk of adverse outcomes due to frailty. A number of frailty screening instruments have been developed to identify older adults at increased risk of frailty. This systematic review and meta-analysis will look to examine the diagnostic accuracy of the Program of Research to Integrate the Services for the Maintenance of Autonomy 7 (PRISMA-7). Methods and analysis: A systematic literature search will be conducted from 2008-February 2020 in PubMed, EMBASE, CINAHL, EBSCO and the Cochrane Library to identify validation studies of the PRISMA-7 tool.  A pre-specified PRISMA-7 score of ≥3 (maximum score 7 points) will be used to identify frailty in older adults. Prospective or retrospective cohort studies, cross-sectional studies and the control arm of randomised controlled trials will be included that attempt to validate the diagnostic accuracy of the PRISMA-7 screening tool in older adults across all healthcare settings when compared to a reference standard. The predictive accuracy of the PRISMA-7 tool will also be explored. Study quality will be assessed by the QUADAS-2 tool. A bivariate random effects model will be used to generate pooled estimates of sensitivity and specificity. Statistical heterogeneity will be explored using validated methods. Ethics and dissemination: Formal ethical approval is not required as primary data will not be collected. The results will be disseminated through a peer-reviewed publication, conference presentation and the popular press. Protocol registration: Awaiting registration with the International Prospective Register for Systematic Reviews (PROSPERO).

The Burden of Frailty on Mood, Cognition, Quality of Life, and Level of Independence in Patients on Hemodialysis: Regina Hemodialysis Frailty Study

Background:

The prevalence of frailty is disproportionately increased in patients with chronic kidney disease (CKD) in comparison with non-CKD counterparts and is the highest in patients on hemodialysis (HD). While the cross-sectional measurement of frailty on HD has been associated with adverse clinical events, there is a paucity of data on longitudinal assessment of frailty and its relationship to outcomes.

Objective:

The objectives were to (1) evaluate changes in frailty status, level of independence, mood, cognition, and quality of life (QoL) over a 12-month period and (2) explore the relationship between frailty status and level of independence, mood, cognition, and QoL at 2 different time points (at baseline and at 1 year).

Design:

This is a prospective cohort study involving 100 prevalent HD patients.

Setting:

Regina General Hospital and Wascana Dialysis Unit in Regina, Saskatchewan, Canada, between January 2015 and January 2017.

Patients:

One hundred prevalent HD patients underwent frailty assessments using the Fried criteria at baseline and 1 year later.

Measurements:

Frailty was assessed using the Fried criteria, which included assessments of unintentional weight loss, weakness (handgrip strength), slowness (walking speed), and questionnaires for physical activity and self-perceived exhaustion. Cognition, mood, and QoL were measured using questionnaires (Montreal Cognitive Assessment [MoCA], Geriatric Depression Scale [GDS], and EuroQol [EQ-5D] utility scores and visual analog scale [VAS], respectively).

Methods:

Frailty status was reported as a binary variable: frail vs. nonfrail (prefrail and robust). Differences across baseline and 1-year groups were assessed using McNemar’s test or Wilcoxon signed-rank test, as appropriate. We assessed the differences between frail and nonfrail groups using the Mann–Whitney U test or chi-square test/Fisher’s exact test where appropriate.

Results:

Ninety-seven of the 100 patients had complete initial assessments. The median (interquartile range [IQR]) duration of dialysis at baseline was 35.5 (13.75-71.75 months). One year later, 22 had died, 10 refused assessments, and 3 had relocated. In comparison with baseline vs 1 year, the number of frail patients was 68.1% vs. 67.7%; prefrail 26.8% vs. 26.1%; robust 5.1% vs. 6.2%; MoCA ≥24, 69% vs. 64.5%; GDS score ≥ 2, 52.8% vs. 47.7%; median EQ-5D utility score 0.81 vs. 0.77; and median EQ-VAS 60 vs. 50. Similarly, in comparison with baseline vs. 1 year, the number of independent patients was 82% vs. 63%, independent with support 17% vs. 31%, and long-term care home 0% vs. 3.1%. Eighteen of the 22 patients (82%) who died were frail. At 1 year, the median (IQR) MoCA was 24 (19-25) vs. 25 (21-26; P = .039) and median (IQR) GDS was 2 (1-3) vs. 1(0-2; P = .034). Likewise, median (IQR) EQ-5D utility score was 0.78 (0.6-0.82) vs. 0.81 (0.78-0.85; P = .023). There were significant changes in self-care (27% vs. 0%), P = 0.006, and daily activities (68.2% vs. 38.1%), P = 0.021.

Limitations:

This is a single-center study, so direct inferences must be interpreted in the context of the demographics of the study population. Patients were undergoing dialysis for a median of 36 months before undergoing initial assessment.

Conclusions:

Frailty and prefrailty in our dialysis patients is near-ubiquitous and will need to be proactively addressed to improve subsequent health care outcomes.

Reliability and Validity of the Tilburg Frailty Indicator in 5 European Countries

OBJECTIVES

To assess the internal consistency, convergent and divergent validity, and concurrent validity of the Tilburg Frailty Indicator (TFI) within community-dwelling older people in Spain, Greece, Croatia, the Netherlands, and the United Kingdom.

DESIGN

Cross-sectional study.

SETTING

Primary care and community settings.

PARTICIPANTS

In total, 2250 community-dwelling older people (60.3% women; mean age = 79.7 years; standard deviation = 5.7).

METHODS

We assessed the reliability and validity of the full TFI as well as its physical, psychological, and social domains. Baseline data of the Urban Health Centers Europe project were used. The internal consistency was assessed with the Cronbach alpha. The convergent and divergent validity were assessed using Pearson correlation coefficients between the domains and alternative measures: the 12-item short-form, Groningen activity restriction scale, 5-item mental well-being scale of the 36-Item Short Form Survey, and the De Jong Gierveld loneliness scale. The concurrent validity was assessed by the area under the receiver operating characteristic curve with physically frail (Survey of Health, Ageing and Retirement in Europe-Frailty Instrument), loss of independence (Groningen activity restriction scale), limited function (Global Activity Limitation Index), poor mental health (5-item mental well-being scale of the 36-Item Short Form Survey), and feeling lonely (De Jong Gierveld loneliness scale) as criteria.

RESULTS

The internal consistency of the full TFI was satisfactory with the Cronbach alpha ≥0.70 in the total population and in each country. The internal consistency of the psychological and social domains was not satisfactory. The convergent and divergent validity of the physical, psychological, and social domains was supported by all the alternative measures in the total population and in each country. The concurrent validity of the full TFI and the physical, psychological, and social domains was supported with most area under the receiver operating characteristic curve ≥0.70 in the total population and in each country.

CONCLUSIONS AND IMPLICATIONS

The TFI is a reliable and valid instrument to assess frailty in community-dwelling older people in Spain, Greece, Croatia, the Netherlands, and the United Kingdom.

Evaluation of an emergency department falls pathway for older people: A patient chart review

The number of older adults presenting to EDs following a fall continues to rise, yet falls management often ignores opportunities for secondary falls risk reduction. Advanced Nurse Practitioners (ANPs) in EDs have an important clinical leadership role in improving outcomes for this group of patients.

AIM

This study describes the development of an ANP led falls pathway in an ED to improve safe discharge. It evaluates compliance with the pathway and referrals to community falls prevention services. It also draws comparison with baseline practice as recorded in 2014.

METHODS

The Falls Pathway involves four steps: 1) screening at triage (3 questions), 2) risk stratification (low, medium, high), 3) risk assessment (lying and standing blood pressure (B/P), timed-up and go (TUG), 4-AT for delirium screening, polypharmacy), and 4) referral to community falls services. We undertook a 12-month chart review of all patients aged 65 years or older presenting following a fall to the ANP service in 2018. We compared data to a baseline audit in 2014; descriptive and Chi squared statistics were used to examine the data.

RESULTS

The 2018 audit involved 77 patients representing 27% of ANP caseload. A repeat fall occurred in 42% (32/77) of cases and 35% (22/77) reported a fear of falling. The Falls Pathway was initiated in nearly 80% (62/77) of patients and compliance with falls risk assessment ranged from 42% for lying and standing B/P to 75% for TUG. In 2014, a review of 59 patient charts showed 27% (16/59) experienced a repeat fall, but other risk factors such as fear of falling were not recorded. In 2018, the majority of patients (88%) discharged home were referred to community falls prevention services compared to 22% in 2014.

CONCLUSION

The Falls Pathway improved falls risk assessment in the ED, identified opportunities for risk reduction and optimised referral to community falls services. The pathway continues to be a valuable tool but requires resources for ongoing implementation among the wider ED team.

Is living alone a risk factor of frailty? A systematic review and meta-analysis

OBJECTIVES

To examine the association of living alone with frailty in cross-sectional and longitudinal studies by a systematic review and meta-analysis.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Community-dwelling older adults with a mean age of >60 years.

METHODS

A systematic search of the literature was conducted according to the PRISMA guidelines. We searched PubMed in February 2019 without language restriction for cohort studies that examined the associations between living alone and frailty. The reference lists of the relevant articles and the included articles were reviewed for additional studies. We calculated pooled odds ratios (OR) of the presence and incidence of frailty for living alone from cross-sectional and longitudinal studies.

RESULTS

Among the 203 studies identified, data of 44 cross-sectional studies (46 cohorts) and 6 longitudinal studies were included in this review. The meta-analysis showed that older adults living alone were more likely to be frail than those who were not (46 cohorts: pooled OR = 1.28, 95 % confidence interval (CI) = 1.13-1.45, p < 0.001). Gender-stratified analysis showed that only men living alone were at an increased risk of being frail (20 cohorts: pooled OR = 1.71, 95 %CI = 1.49-1.96), while women were not (22 cohorts: pooled OR = 1.00, 95 %CI = 0.83-1.20). No significant association was observed in a meta-analysis of longitudinal studies (6 cohorts: pooled OR = 0.88, 95 %CI = 0.76-1.03).

CONCLUSIONS/IMPLICATIONS

The present systematic review and meta-analysis showed a significant cross-sectional association between living alone and frailty, especially in men. However, living alone did not predict incident frailty. More studies controlling for important confounders, such as social networks, are needed to further enhance our understanding of how living alone is associated with frailty among older adults.

Examining fall risk among formerly homeless older adults living in permanent supportive housing

Although permanent supportive housing (PSH) has been credited with a decline in the number of chronically homeless adults in the United States since 2007, the extent to which PSH can accommodate the needs of a prematurely aging population, including reducing the likelihood of falls, is unclear. The objective of this study is to examine the prevalence and correlates of falls with a sample of 237 tenants (45- to 80-year olds) from two PSH programmes in Los Angeles from 1 January 2017 to 10 August 2017. We also explore the location and severity of fall-related injury using a subsample of 66 tenants. Standard surveys queried demographics, health status, history of homelessness and falls. Multivariable logistic regression assessed the correlates of falling in the past year. More than half of the sample had fallen and more than 40% had multiple falls in the past year. Functional impairment, frailty and persistent pain were all associated with increased fall risk. For the 66 tenants who provided more detailed fall information, more than 40% fell at home and of those nearly half fell in their bathroom. Fall-related injuries were common, with more than one-third of the subsample experiencing serious injury. These findings suggest that fall prevention is needed in PSH but that more research is needed to understand the degree to which individual and environmental risk factors are contributing to falls.

Validation of the Risk Analysis Index for Evaluating Frailty in Ambulatory Patients

BACKGROUND

Frailty is a marker of dependency, disability, hospitalization, and mortality in community-dwelling older adults. However, existing tools for measuring frailty are too cumbersome for rapid point-of-care assessment. The Risk Analysis Index (RAI) of frailty is validated in surgical populations, but its performance outside surgical populations is unknown.

OBJECTIVE

Validate the RAI in ambulatory patients.

DESIGN, SETTING, AND PARTICIPANTS

Observational cohort study of outpatient surgical clinics within the University of Pittsburgh Medical Center Healthcare System between July 1, 2016, and December 31, 2016. Frailty was assessed using the RAI. Current Procedural Terminology codes following RAI assessment identified patients with and without minor office-based procedures (eg, joint injection, laryngoscopy).

MAIN OUTCOMES AND MEASURES

All-cause 1-year mortality, assessed by stratified Cox proportional hazard models.

RESULTS

Of 28,059 patients, 13,861 were matched to a minor, office-based procedure and 14,198 did not undergo any procedure. The mean (SD) age was 56.7 (17.2) years; women constituted 15,797 (56.3%) of the cohort. Median time (interquartile range 25th-75th percentile) to measure RAI was 30 (22-47) seconds. Mortality among the frail was two to five times that of patients with normal RAI scores. For example, the hazard ratio for frail ambulatory patients without a minor procedure was 3.69 (95% confidence interval [CI] = 2.51-5.41), corresponding to 30-, 180-, and 365-day mortality rates of 2.9%, 11.2%, and 17.4%, respectively, compared to 0.3%, 2.3%, and 4.0% among patients with normal RAI scores. Discrimination of mortality (overall, and censored at 30, 180, and 365 days) was excellent, ranging from c = 0.838 (95% CI = 0.773-0.902) for 30-day mortality after minor procedures to c = 0.909 (95% CI = 0.855-0.964) without a procedure.

CONCLUSION

RAI is a valid, easily administered tool for point-of-care frailty assessment in ambulatory populations that may help clinicians and patients make better informed decisions about care choices-especially among patients considered high risk with a potentially limited life span.

Nutritional Status and Risk Factors for Frailty in Community-Dwelling Older People: A Cross-Sectional Study

OBJECTIVE

This study aims to assess the relationship that frailty has with nutritional status and functional risk factors in community-dwelling older adults.

METHODS

Cross-sectional study in community-dwelling older people, independent for walking and without impaired cognition. Frailty was assessed by Fried criteria. Nutritional status was analyzed by the Mini Nutritional Assessment Short Form (MNA-SF), biochemical markers (albumin, total proteins, cholesterol, lymphocytes, and hemoglobin); and anthropometric parameters (body mass index [BMI], body fat percentage, handgrip, and perimeters). A comprehensive geriatric assessment analyzed other risk factors: functionality, cognition, falls, comorbidity, polypharmacy, physical activity, and quality of life (QoL).

RESULTS

We included 564 elderly people with a mean age of 76.05 (standard deviation 3.97) years; 63.1% (n = 356) were women, and 83.9% (n = 473) were prefrail, and frail. The sample presented high functionality and a nutritional status with a predominance of overweight and obesity. Factors associated with frailty (R² = 0.43) were age over 75 years (odds ratio [OR] 3.31, 95% confidence interval [CI] 1.76, 6.21; p < 0.001), female gender (OR 2.37, 95% CI 1.24, 4.52; p = 0.009), anemia (OR 2.45, 95% CI 1.19, 5.02; p = 0.015), falls (OR 1.94, 95% CI 1.12, 3.25; p = 0.016) and the fear of falling (OR 4.01: 95% CI 1.76, 9.16; p = 0.001). Performing more than 3 weekly hours of physical activity was found to be a protective factor (OR 0.23, 95% CI 0.15, 0.35; p < 0.001).

CONCLUSIONS

The relationship between frailty and malnutrition in functionally independent community-dwelling older people is unclear. More studies are needed to know what nutritional markers are related to frailty, cognition, and functionality in order to discriminate the risk factors for community-dwelling older people at risk of malnutrition and dependency.
