Prevalence of frailty in older adults in outpatient physiotherapy in an urban region in the western part of Germany: a cross-sectional study

Effectiveness of physiotherapist-led tele-rehabilitation for older adults with chronic conditions: a systematic review and meta-analysis

BACKGROUND

Older adults live with chronic conditions worldwide. The aim of this systematic review was to determine the effectiveness of physiotherapist-led (PT-led) tele-rehabilitation on various health outcomes.

METHODS

Six databases were searched. Eligible studies were randomized controlled trials that included older adults (≥65 years) who had ≥1 chronic condition, and evaluated tele-rehabilitation (e.g., video, telephone) that was PT-led or overseen. Screening and data extraction were performed in duplicate. Meta-analyses were performed where appropriate. Cochrane's Risk of Bias 2.0 tool was used.

RESULTS

Fifteen studies were included. A meta-analysis of studies of knee osteoarthritis demonstrated that tele-rehabilitation is more effective than usual care for functional mobility (MD= -2.72, 95% CI= -3.56, -1.88, p < 0.001), quadriceps strength (MD= 15.54, 95% CI= 10.14, 20.95, p < 0.001), pain (MD= -1.2, 95% CI= -2.09, -0.39, p = 0.004) and physical function (MD= -5.95, 95% CI= -8.32, -3.58, p < 0.001). No clear differences were found between tele-rehabilitation and usual care or comparator interventions for outcomes related to physical activity level, gait speed, mental health, and quality of life.

CONCLUSIONS

PT-led tele-rehabilitation appears to be comparable to traditional methods at improving outcomes in older adults with various chronic conditions. However, high-quality trials are needed so future conclusions on the effectiveness of tele-rehabilitation can be made.

Gender-specific linkages: frailty, polypharmacy, anti-cholinergic burden, and 5-year mortality risk-a real-world analysis

Background

With higher age, frailty escalates the risk of falls, unexpected physical dysfunction, hospitalization, and mortality. Polypharmacy in the older population is a major challenge that not only increases medical costs, but also may worsen the risk of hospitalization and death. More importantly, the properties of anti-cholinergic drugs contribute various negative effects. This study aimed to investigate the sex difference in the association of polypharmacy, anticholinergic burden, and frailty with mortality.

Methods

Participants older than 65 years who attended the geriatric outpatient clinic of the study center between January 2015 and July 2020 were invited to participate in this retrospective study. Comprehensive geriatric assessment data were collected and the phenotype of frailty was determined by Fried's criteria. Cox regression and the Kaplan-Meier curve were used to identify risk factors of 5-year survival along with intergroup differences in the risks.

Results

Of the 2,077 participants, 47.5% were female. The prevalence of frailty and the rate of polypharmacy were 44.7% and 60.6%, respectively. Higher age, male sex, low body mass index, low Mini-Mental State Examination scores, low activities of daily living, frailty status, polypharmacy, and a high Charlson Comorbidity Index score, and greater anticholinergic burden were significant risk factors that were associated with the 5-year all-cause mortality. Male patients with frailty exhibited the highest risks of mortality compared with male patients without frailty and female patients with or without frailty. Polypharmacy was significantly associated with a higher 5-year mortality rate in the frail male group compared with the non-frail male. In frail female group, individuals with a higher anticholinergic burden (as indicated by the Anticholinergic Cognitive Burden Scale) from drug usage exhibited an elevated 5-year mortality rate.

Conclusions

Polypharmacy and greater anticholinergic burden, synergistically interacted with frailty and intensified the 5-year mortality risk in a gender-specific manner. To mitigate mortality risks, clinicians should prudently identify polypharmacy and anticholinergic burden in the older population.

Prevalence and health outcomes of polypharmacy and hyperpolypharmacy in older adults with frailty: A systematic review and meta-analysis

Polypharmacy is a prevalent issue in older adults, associated with a wide range of adverse health outcomes, amplified in those with frailty. This review aims to synthesize current literature on the prevalence and health outcomes of polypharmacy and hyperpolypharmacy in older adults with frailty. A systematic search was carried out within ten databases till December 2021. Data was extracted using a piloted data extraction form, and methodological quality was assessed using JBI critical appraisal checklists. Meta-analyses were conducted for prevalence, and narrative synthesis was conducted for the health outcomes of polypharmacy and hyperpolypharmacy in older adults with frailty. Heterogeneity was assessed using Chi² and I² statistics, with sensitivity and subgroup analyses performed to explore sources of heterogeneity. Sixty-six studies were included for this review. The overall pooled prevalence of polypharmacy and hyperpolypharmacy was 59% and 22% respectively. When stratifying the studies by setting, WHO regions, in eighteen frailty assessment instruments, and by its year of publication, subgroup analysis found the highest rates of prevalence in the hospital setting (71%), in the European region (68%), when Reported Edmonton Frail Scale was used (96%), and in studies published in 2015 (86%). Additionally, frail older adults with polypharmacy were less likely to experience an improvement in frailty states, had higher risks of mortality, were more likely to suffer adverse hospital-related outcomes, and required additional assistance compared to those without polypharmacy. Therefore, the high prevalence and poorer health outcomes urges the healthcare providers and health policymakers to develop and implement preventative and restorative measures targeted at the adverse outcomes associated with polypharmacy and hyperpolypharmacy in older adults with frailty.

Prevalence of Prefrailty and Frailty Among Older Adults in Germany: A Systematic Review, Meta-Analysis and Meta-Regression

Background

Various studies have identified the prevalence of prefrailty and frailty among older adults in Germany. Nevertheless, there is no review systematically synthesizing these studies. Thus, our aim was to close this gap in knowledge. Moreover, another aim was to perform a meta-analysis to synthesize the pooled prevalence of prefrailty and frailty. A further aim was to explore potential sources of heterogeneity based on a meta-regression.

Methods

A number of three electronic databases (PubMed, PsycINFO, and CINAHL) were searched (plus an additional hand search). The observational studies that determine the prevalence of frailty among older adults aged 65 years and above in Germany were included, whereas disease-specific samples were excluded. Data extraction included the description of the sample, operationalization of frailty, statistical analysis, sample characteristics and main findings. The established Joanna Briggs Institute (JBI) standardized critical appraisal instrument for prevalence studies was used for evaluating the quality of the studies. Important steps were performed by two reviewers.

Results

In sum, a number of 12 studies were included. The prevalence of frailty varied from about 2.4 to 25.6%. The pooled prevalence of frailty was 13.7% (95% CI: 9.0 to 18.5%). There was a significant heterogeneity among the studies (I² = 98.9%, p < 0.001). The pooled prevalence of prefrailty was 40.2% (95% CI: 28.3 to 52.1%; I² = 99.6%, p < 0.001). Some evidence of a publication bias exists. Meta-regressions showed that some of the heterogeneity was explained by the tool to quantify frailty and the average age of the respective sample.

Conclusion

Particularly, the high prevalence of prefrailty should be highlighted since it is important to prevent individuals in old age from developing to frail status. This knowledge is important for the German society as a whole and for relevant stakeholders.

Prevalence and associated factors of frailty in patients attending rural and urban geriatric clinics

OBJECTIVES

To investigate the prevalence and factors associated with frailty in rural and urban older outpatients in Vietnam.

METHODS

This cross-sectional study included 1084 outpatients (aged ≥60 years; mean age 71.7 ± 7.4 years; female 65%) from rural (n = 600) and urban (n = 484) geriatric clinics from December 2019 to July 2020. Frailty was assessed using Fried frailty phenotype. Factors associated with frailty were assessed using logistic regression.

RESULTS

Overall, frailty prevalence was 28% (rural, 26%; urban, 30%; p = 0.220). Factors associated with frailty were older age (odds ratio [OR] 1.16, 95% confidence interval [CI] 1.13-1.20, p < 0.001), being underweight (OR 1.88, 95% CI 1.10-3.27, p = 0.025) and limitations in activities of daily living (ADLs) (OR 6.04, 95% CI 1.63-22.41, p = 0.007) and instrumental ADLs (OR 5.83, 95% CI 3.74-9.08, p < 0.001). Higher education (OR 0.47, 95% CI 0.29-0.76, p = 0.002) and productive work (OR 0.39, 95% CI 0.21-0.71, p = 0.002) were protective factors against frailty.

CONCLUSIONS

In Vietnam, the prevalence of frailty in older outpatients was 28%, though not significantly different between urban and rural areas. Older age, being underweight and limitations in functional status can increase the odds of frailty, but higher education and productive work can reduce the odds of frailty.

Age-stratified differences of physical capacity in rural community-dwelling Taiwanese older women: A cross-sectional study

OBJECTIVES

Physical capacity decline may precede physical disability. We explored age-related physical capacity decline among rural community-dwelling Taiwanese older women to provide reference values and to identify indicators of early-onset decline in physical capacity.

METHODS

Older women aged 65-96 were recruited from rural community centers. Physical capacity was measured by handgrip strength (HS), gait speed (GS), five-times-sit-to-stand (5xSTS), timed up and go (TUG), and the Berg balance scale (BBS). Participants were stratified into four age groups: 65-69, 70-74, 75-79, and ≥80 years.

RESULTS

Of 137 participants, 61 % exhibited poor 5xSTS, 34-49 % showed low HS, poor TUG and BBS, and 26 % had slow GS. The mean values in GS, HS, 5xSTS, TUG, and BBS were 1.02 m/s, 17.8 kg, 14.5 s, 12.6 s, and 50 points, respectively. Abnormal mean values were first noted at age 70-74 years for 5xSTS, age 75-79 years for HS, TUG, and BBS, and age ≥80 years for GS. Also, more than half the participants exhibited the first poor 5xSTS at age 70-74 years; the first poor HS and TUG at age 75-79 years; and lastly, the first poor BBS and GS at age ≥80 years. At age 65-69 years, 14-41 % of participants reported poor performance in all measures except for GS.

CONCLUSIONS

Low HS and poor 5xSTS and TUG performance were more common and had earlier onset than slow GS. More attention should be directed toward the 5xSTS, TUG, and HS in rural community-dwelling Taiwanese older women.

Frailty Phenotype Prevalence in Community-Dwelling Older Adults According to Physical Activity Assessment Method

Introduction

Studies have described varying prevalences of frailty as determined by Fried’s frailty phenotype. Comparability may be limited due to frailty phenotype modifications, especially the low physical activity criterion.

Purpose

This study aimed to determine the variability of frailty phenotype prevalence according to the physical activity assessment method.

Patients and Methods

In a cross-sectional analysis, frailty phenotype prevalence was assessed in community-dwelling older adults. The low physical activity criterion of the frailty phenotype was determined by using five different questionnaires and an accelerometer, and three different cut-point models.

Results

In 47 participants, frailty phenotype prevalence varied between 14.9% and 31.9%, depending on the model used to assess physical activity.

Conclusion

The method of physical activity assessment and the choice of cut-points for low physical activity considerably impact frailty phenotype prevalence. More efforts to standardize and adhere to the low physical activity criterion seem warranted. The calculation of correction factors between commonly used sets of low physical activity criteria might allow better comparisons of published prevalence rates.
