Multidimensional frailty as a predictor of mortality among older adults: a systematic review and meta-analysis.

OBJECTIVE: This systematic review examined studies that assessed the relationship between mortality risk and multidimensional frailty. The pooled risk of mortality was estimated via a meta-analysis. DESIGN: A systematic review and meta-analysis. METHODS: A systematic search for potentially eligible literature was conducted on January 2, 2023, using five electronic databases: Web of Science, CINAHL, PubMed, the Cochrane Library and Embase. This review included cohort or longitudinal studies examining the association between multidimensional frailty/prefrailty and mortality in older adults. The quality of the included studies was evaluated via the Quality in Prognosis Studies (QUIPS) tool. Two independent researchers identified eligible studies and extracted the data. The data analyses were performed via STATA, version 15.0. RESULTS: A total of 24 studies with 34,664 participants were included. The 24 studies were published between 2012 and 2022, with most studies being performed in Italy (n = 16). The sample sizes of the included studies ranged from 71 to 12,020. Most included studies were conducted in hospital settings. The QUIPS bias assessment results showed that the most frequent source of potential bias was study confounding. The meta-analysis results showed that multidimensional frailty was a significant predictor of mortality (HR = 5.48, 95% CI = 3.91-7.67, p < 0.001). In addition, multidimensional prefrailty was also a significant predictor of mortality (HR = 2.56, 95% CI = 2.17-3.02, p < 0.001). The results of the meta-analysis using the ORs revealed that multidimensional frailty was a risk factor for mortality in older people (OR = 4.59, 95% CI = 2.47-8.55, p < 0.05). CONCLUSIONS AND IMPLICATIONS: This systematic review of the relationship between multidimensional frailty and mortality found that multidimensional frailty/prefrailty is a predictor of mortality. More studies should be conducted in community dwelling populations and nursing homes.

A transitional care program in a technologically monitored in-hospital facility reduces the length of hospital stay and improves multidimensional frailty in older patients: a Randomized Clinical Trial.

BACKGROUND: Longer length of hospital stay (LOS) negatively affects the organizational efficiency of public health systems and both clinical and functional aspects of older patients. Data on the effects of transitional care programs based on multicomponent interventions to reduce LOS of older patients are scarce and controversial. AIMS: The PRO-HOME study aimed to assess the efficacy in reducing LOS of a transitional care program involving a multicomponent intervention inside a technologically monitored in-hospital discharge facility. METHODS: This is a Randomized Clinical Trial on 60 patients (≥65 years), deemed stable and dischargeable from the Acute Geriatrics Unit, equally assigned to the Control Group (CG) or Intervention Group (IG). The latter underwent a multicomponent intervention including lifestyle educational program, cognitive and physical training. At baseline, multidimensional frailty according to the Multidimensional Prognostic Index (MPI), and Health-Related Quality of Life (HRQOL) were assessed in both groups, along with physical capacities for the IG. Enrolled subjects were evaluated after 6 months of follow-up to assess multidimensional frailty, HRQOL, and re-hospitalization, institutionalization, and death rates. RESULTS: The IG showed a significant 2-day reduction in LOS (median days IG = 2 (2-3) vs. CG = 4 (3-6); p < 0.001) and an improvement in multidimensional frailty at 6 months compared to CG (median score IG = 0.25(0.25-0.36) vs. CG = 0.38(0.31-0.45); p = 0.040). No differences were found between the two groups in HRQOL, and re-hospitalization, institutionalization, and death rates. DISCUSSION: Multidimensional frailty is a reversible condition that can be improved by reduced LOS. CONCLUSIONS: The PRO-HOME transitional care program reduces LOS and multidimensional frailty in hospitalized older patients. TRIAL REGISTRATION: ClinicalTrials.gov n. NCT06227923 (retrospectively registered on 29/01/2024).

In Support of Multidimensional Frailty: A Structural Equation Model from the Canadian Positive Brain Health Now Cohort.

The objective of this study was to estimate the structure and relationships between four h ypothesized frailty dimensions (physical, emotional, cognitive, and social) and the extent to which personal and HIV-related factors and comorbidity associate with these frailty dimensions. This is a secondary analysis of an existing dataset arising from Positive Brain Health Now study (n = 856) in people aging with HIV (mean age: 52.3 ± 8.1 years). Structural equation modeling (SEM) models were applied to two cross-sections of the data: one at study entry and one at second visit, 9-month apart. Multidimensional frailty was modeled based on the combined Wilson-Cleary and International Classification of Functioning, Disability and Health framework. Four dimensions were operationalized with patient-reported and self-report measures from standardized questionnaires. The SEM model from the first visit was replicated using data from the second visit, testing measurement invariance. The proposed model showed acceptable fit at both visits (including no violation of measurement invariance). The final model for the first visit showed that sex, body mass index, HIV diagnosis pre-1997, current or nadir CD4 counts, and comorbidity did not associate with any frailty dimension; however, age (ß range: 0.12-0.25), symptoms (ß range: -0.35 to -0.58), and measured cognition (ß range: 0.10-0.24) directly associated with all frailty dimensions. The model remained stable across the two visits. This study contributes evidence for operationalizing multidimensional frailty. Evidence-based interventions are available for many of the measures considered here, offering opportunities to improve the lives of people with frailty in the context of HIV.

Prevalence of multidimensional frailty among community-dwelling older adults: A systematic review and meta-analysis.

OBJECTIVE: The aims of this systematic review were to explore the pooled prevalence of multidimensional frailty assessed by the Tilburg Frailty Indicator among community-dwelling older adults. DESIGN: A systematic review and meta-analysis. METHODS: A comprehensive literature search was conducted across multiple databases, including PubMed, Web of Science, Embase, the Cochrane Library, CINAHL and three Chinese databases. Two independent researchers selected the literatures, extracted the data and evaluated the quality. All statistical analyses were performed using STATA version 16.0. RESULTS: There were 66 studies with a total of 40,597 individuals that were eligible for the meta-analysis. Data from the meta-analysis revealed the pooled prevalence of 42 % for multidimensional frailty (95 % CI: 38 %-45 %, I2 = 98.9 %, T2 = 0.024, p < 0.001). Among the six studies that provided data for different age groups, the results demonstrated an increasing trend in the prevalence of multidimensional frailty with advancing age. The results of gender-stratified analysis proved that the pooled prevalence of multidimensional frailty in women (45 %, 95 % CI: 39 %-51 %, p < 0.001) was higher than that in men (33 %, 95 % CI: 28 %-39 %, p < 0.001). Based on different education levels, the prevalence of multidimensional frailty is highest in the primary elementary or illiterate group (41 %, 95 % CI: 30 %-52 %, p < 0.001). According to different marital status types, the pooled prevalence of multidimensional frailty in the married group was significantly lower (36 %, 95 % CI: 28 %-43 %) than that in the unmarried, divorced or widowed group (51 %, 95 % CI: 37 %-65 %). CONCLUSIONS: Through a comprehensive review, we identified that 42 % of elderly individuals living in communities exhibit multidimensional frailty, indicating that multidimensional frailty is relatively common in this population. Stratified analysis revealed that advanced age, female gender, lower education level and unmarried status were associated with higher rates of multidimensional frailty.

Health-related quality of life measures provide information on the contributors, components, and consequences of frailty in HIV: a systematic mapping review.

PURPOSE: Frailty in HIV is extensively explored in epidemiological and clinical studies; it is infrequently assessed as an outcome in routine care. The focus on health-related quality of life (HRQL) measures in HIV presents a unique opportunity to understand frailty at a larger scale. The objective was to identify the extent to which generic and HIV-related HRQL measures capture information relevant to frailty. METHODS: A systematic mapping review using directed and summative content analyses was conducted. An online search in PubMed/Medline identified publications on frailty indices and generic and HIV-related HRQL measures. Directed content analysis involved identifying contributors, components, and consequences of frailty from the frailty indices based on the International Classification of Functioning, Disability, and Health framework. Summative content analysis summarized the results numerically. RESULTS: Electronic and hand search identified 447 review publications for frailty indices; nine reviews that included a total of 135 unique frailty indices. The search for generic and HIV-related HRQL measures identified 2008 records; five reviews that identified 35 HRQL measures (HIV-specific: 17; generic: 18). Of the 135 frailty indices, 88 cover more than one frailty dimension and 47 cover only physical frailty. Contributors to frailty, like sensory symptoms and nutrition, are extensively covered. Components of frailty such as physical capacity, cognitive ability, and mood are also extensively covered. Consequences of frailty namely self-rated health, falls, hospitalization, and health services utilization are incomprehensively covered. HRQL measures are informative for contributing factors, components of frailty, and a consequence of frailty. CONCLUSION: HRQL items and measures show a strong potential to operationalize multidimensional frailty and physical frailty. The study suggests that these measures, connected to evidence-based interventions, could be pivotal in directing resources toward vulnerable populations to mitigate the onset of frailty.

Associations of individual chronic diseases and multimorbidity with multidimensional frailty.

OBJECTIVE: To examine the associations between individual chronic diseases and multidimensional frailty comprising physical, psychological, and social frailty. METHODS: Dutch individuals (N = 47,768) age ≥ 65 years completed a general health questionnaire sent by the Public Health Services (response rate of 58.5 %), including data concerning self-reported chronic diseases, multidimensional frailty, and sociodemographic characteristics. Multidimensional frailty was assessed with the Tilburg Frailty Indicator (TFI). Total frailty and each frailty domain were regressed onto background characteristics and the six most prevalent chronic diseases: diabetes mellitus, cancer, hypertension, arthrosis, urinary incontinence, and severe back disorder. Multimorbidity was defined as the presence of combinations of these six diseases. RESULTS: The six chronic diseases had medium and strong associations with total ((f2 = 0.122) and physical frailty (f2 = 0.170), respectively, and weak associations with psychological (f2 = 0.023) and social frailty (f2 = 0.008). The effects of the six diseases on the frailty variables differed strongly across diseases, with urinary incontinence and severe back disorder impairing frailty most. No synergetic effects were found; the effects of a disease on frailty did not get noteworthy stronger in the presence of another disease. CONCLUSIONS: Chronic diseases, in particular urinary incontinence and severe back disorder, were associated with frailty. We thus recommend assigning different weights to individual chronic diseases in a measure of multimorbidity that aims to examine effects of multimorbidity on multidimensional frailty. Because there were no synergetic effects of chronic diseases, the measure does not need to include interactions between diseases.

The importance of prognosis in geriatric patients attending the emergency department: a comparison between two common short geriatric assessment tools.

BACKGROUND: The use of short geriatric tools in the emergency department (ED) is increasing, but the literature is still conflicting. The aim of this study is to compare the precision and the accuracy of two short geriatric assessment tools to predict mortality in a cohort of older patients attending the ED. METHODS: A retrospective study was conducted including patients ≥ 65 years, attending the ED and transferred to a medical assessment unit from February to July 2022. Clinical Frailty Scale (CFS) and Brief Multidimensional Prognostic Index (Brief MPI) were administered. The association between Brief MPI and CFS and mortality was analysed via area under the curve (AUC) with its 95% confidence intervals (CIs), the C-statistics and a multivariate Cox's regression analysis, in the latter case reporting the data as hazard ratios (HRs) with their 95% CI. RESULTS: Among the 579 patients enrolled (mean age: 77 years), both Brief MPI and CFS showed a good accuracy in predicting mortality (AUC: 0.72; 95% CI: 0.61-0.83 for Brief MPI; 0.754; 95% CI: 0.65-0.83 for CFS). The discrimination of Brief MPI and CFS in predicting mortality was excellent, since the C-index of the Brief MPI was 0.85 and of CFS = 0.84. In the multivariate analysis, the risk for mortality was significantly increased for frailer subjects (HR 4.65; 95% CI: 1.45-15.00 for Brief MPI > 0.66; HR = 9.24; 95% CI: 1.16-76.90 for CFS > 6). CONCLUSIONS: Brief MPI and CFS showed a good accuracy/precision to predict mortality in older patients attending the ED. Considering that they are quick to perform, their introduction in ED clinical practice could be extremely helpful.

Accumulating awareness on the clinical significance and relevance of frailty in cirrhosis: Time to dig deeper into mechanistic basis!

Frailty corresponds to an emerging construct in the hepatology which is originally introduced as a validated geriatric syndrome regarding increased vulnerability to pathophysiological stressors. As for patients with cirrhosis, the presence of frailty is indicative of debilitating conditions that subjects are prone to deleterious acute insults and have difficulties to restore even if the underlying liver function partially returned to normal levels. Since this conceptual development, a variety of tools assessing frailty have been proposed and evaluated in the context of cirrhosis. A recent performance-based metric for frailty, designated as Liver Frailty Index, has broadly been applied in patients with cirrhosis and exhibited acceptable predictive ability in relation to disease progression, mortality and hospitalization. However, those functional tests measuring frailty may be impossible to perform in circumstance that patients are critically ill or undergoing detrimental events. An interesting modality indicates the use of alternative tests to evaluate frailty, which may be more adaptable and of choice for specific subgroups. The interrelation between frailty and various cirrhosis-associated pathological entities is of clinical importance and implication. Noticeably, it is imperative to clarify these complex linkages to highlight novel therapeutic targets or interventional endpoints. The efficient and effective management of frailty is still challenging, but many attempts have been made to overcome barriers of affordability and availability. Some clinical trials on small scale revealed that home-based exercise and individualized nutrition therapy show benefits in patients with cirrhosis, and high adherence to the treatment regimen may direct better efficacy and performance.

A multidimensional approach to older patients during COVID-19 pandemic: a position paper of the Special Interest Group on Comprehensive Geriatric Assessment of the European Geriatric Medicine Society (EuGMS).

PURPOSE: The COVID-19 pandemic has been a dramatic trigger that has challenged the intrinsic capacity of older adults and of society. Due to the consequences for the older population worldwide, the Special Interest Group on Comprehensive Geriatric Assessment (CGA) of the European Geriatric Medicine Society (EuGMS) took the initiative of collecting evidence on the usefulness of the CGA-based multidimensional approach to older people during the COVID-19 pandemic. METHODS: A narrative review of the most relevant articles published between January 2020 and November 2022 that focused on the multidimensional assessment of older adults during the COVID-19 pandemic. RESULTS: Current evidence supports the critical role of the multidimensional approach to identify older adults hospitalized with COVID-19 at higher risk of longer hospitalization, functional decline, and short-term mortality. This approach appears to also be pivotal for the adequate stratification and management of the post-COVID condition as well as for the adoption of preventive measures (e.g., vaccinations, healthy lifestyle) among non-infected individuals. CONCLUSION: Collecting information on multiple health domains (e.g., functional, cognitive, nutritional, social status, mobility, comorbidities, and polypharmacy) provides a better understanding of the intrinsic capacities and resilience of older adults affected by SARS-CoV-2 infection. The EuGMS SIG on CGA endorses the adoption of the multidimensional approach to guide the clinical management of older adults during the COVID-19 pandemic.

Effectiveness, satisfaction and meaningfulness of a 6-step detection and prevention program for frail community-dwelling older adults: a mixed-method evaluation.

BACKGROUND: As people age, the risk of becoming frail increases, often leading to negative outcomes and less well-being. Within the light of prevention, early detection and guidance to the right care and support is crucial. This study aimed to give an overview of the descriptive results of the D-SCOPE program and evaluate the process. METHODS: The D-SCOPE program was developed as a detection and prevention program for frail community-dwelling older adults. The program creates a continuum of care and support, consisting of 6 steps: (1) Targeted case-finding using risk profiles for purposeful selection, (2) Preventive home-visit by an older volunteer, (3) Home visits by a professional, (4), Warm referral, (5) Monthly follow-up and (6) Long-term follow-up by home visit. The effectiveness of this program, in terms of satisfaction and meaningfulness, was studied quantitatively by means of a randomized controlled trial amongst 869 people with a frailty risk profile and qualitatively by 15 focus groups interviews. RESULTS: The quantitative study revealed that 83.9% of the participants found the different home visits within the D-SCOPE program useful. The focus group interviews shed light on several issues and advantages: a more efficient case finding due to the applied risk factors for frailty, a more intensive tailor-made care and support due to the warm referral, the importance of both small-scaled and larger interventions based on the wishes irrespective of the state of frailty of the older persons, the focus on a strengths-based instead of a deficit-based approach and the follow up as being one of the greatest strengths of the project. However, to fully understand the benefits of the program a shift in mind from intervention to prevention is necessary. CONCLUSIONS: Our quantitative data show that most participants found the home visits meaningful and were satisfied with the intervention. The qualitative findings provided more insights into the experiences of the participants with the process. Based on these insights of the 6-step model of preventive home visits, municipalities and organizations can apply this model to carry out more targeted home visits. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov, on 30/05/2017, identifier: NCT03168204.
